Pillow shape

Sodium cyanide is sold as granular or powder, pillow-shaped briquettes of 15-g and 30-g sizes, tablets of 30 g, and 30% aqueous solution. List price in 1991 was 1.85/kg. 

Almost 100 million pounds of starch are now being used to bond charcoal dust into easy-to-handle, pillow-shaped briquettes. In order to get the proper strength characteristics, from 5% to 8% of the charcoal weight must be starch and to be an effective binder, the starch must be cooked-out before addition to the charcoal. Thus, it may be either a pregelled starch that has been cooked and dried by the starch manufacturer, or it may be a granular starch that the briquetter must paste. Unmodified cornstarch processed through a jet cooker has proven to be the most effective binder for this market. 

The characteristics of the chosen gum base that is used depends not only upon the chewing properties of the finished product but also upon the type of gum being made. For example, chewing gum that is being pan coated has to be more rigid than gum that is being presented as a stick. If too soft a gum base is used on a pan-coated gum, instead of the product being presented as a neat pillow shape it will be distorted. 

The detailed release geometry. This is governed by the pocket shape. A pillow shape with the axis of its partial cylinder across the rollers and conical sides of wide angle will probably be the best. It is suggested that at no point on the cup surface should the normal to the surface differ in direction from the roll radius by more than 65° (Figure 224). 

Probably the most common briquette forms are egg, almond, and pillow shapes. Other forms are tear drop, walnut, and lentil as well as bar or stick shapes. If the pocket configuration does not approximate a regular polygon, the land area between the cups becomes relatively large, which increases the amount of web between the briquettes and wastes compaction pressure.

The most economical pressure agglomeration method, which is also applicable for a wide range of capacities, uses roller presses (see Section 4.2.2.4). Depending on the surface configuration of the rollers, either compacted sheets are produced which are subsequently crushed and screened into a granular product or, if the rollers are pocketed, briquettes are formed. For waste treatment and the production of secondary raw materials (recirculation of valuable components) the latter is often preferred. Briquettes are usually pillow shaped and almost monosized, featuring a volume that may typically range between 20 and 100 cm3. 

The female then spins a pillow-shaped silk egg sack, into which she lays over lOO eggs. She cleans and turns the egg sack several times during incubation and will defend it vigorously if disturbed. The spiderlings hatch about three weeks later, and stay with the mother for a few months. After two molts, they leave her burrow, eventually making their own burrows. Juvenile males will stay in their burrows until their final adult molt, after which they will become wanderers. Funnel webs mature in about two to four years, with the females living to ten or more years, and the males dying about six to nine months after maturity.

Since relatively small, briquetted, almond or pillow-shaped ice can be easily poured and metered, it became a superior cold-packing material. Roller presses were preferred for this operation because the thermal contraction of machine parts does not cause operational problems. Dry ice, compressed and shaped solid COj, is an even better material for cold packing because it evaporates rather than melts and its cooling capacity is almost three-times higher than that of water ice. Dry ice compacts are typically made with hydraulic presses and are still used today. 

Fig. 6.9-8 depicts three typical hot briquetting systems for DRI. Hot feed in the form of reduced pellets and/or lumps and/or fines is forced by a vertical screiv feeder into the nip between two counter-rotating rollers with matched pockets [B.48, B.97]. The briquettes are pillow shaped, 90-140 mm long, 50-60 mm wide, about 30 mm thick, and weigh 450-800 g each (Fig. 6.9-9). Although the rollers are set closely together, a distance of 2-3 mm is maintained between their surfaces to make sure that there is...

The briquettes curved outer surface (pillow shape) insures sufficient voids in the furnace charge and does not prevent the free flow of hot gases during melting. 

Drying the gypsum to < 1% moisture content and pressing and shaping it into finished, pillow-shaped briquettes with roller presses (Chapter 5, Fig. 5.11, lower right). 

These problems are resolved by briquetting. The DMT flakes are readily densified and bonded under moderate pressure in a roller press that is equipped with a screw feeder and pillow shaped pockets. The briquettes have high density and are well formed. During a screening operation they are separated into singles and leakage and land areas that surround the briquettes and are rubbed-off on the screen, are recirculated to the press. The briquettes have a volume of about 4cm, are about 20 mm square and 14 mm thick, pack, store, and handle well, and can be easily metered and remelted. 

The most common agglomeration technology for the conversion of sodium cyanide into a safe product is briquetting with roller presses. Almond- or pillow-shaped compacts are made. The systems are completely enclosed, equipped with highly effective dust collection systems to safeguard the operators, and executed in stainless steel to keep corrosion in check. The discharge from the roller press is screened within the enclosed system, fines are recirculated internally to the briquetter feed bin, and dean product is immediately packed into sealed containers. 

The character of qnasiparticles in CeRu2Si2 varies quite strongly over the Fermi snrface. There are three Z-centered hole ellipsoids with rather light qnasiparticles. The states on the pillow-shaped Z-centered hole surface displayed in fig. 16, however, have predominantly f-character and therefore yield the dominant contribntion to the specific heat Experimentally, one finds heavy and light qnasiparticles coexisting on the multiply-cormected sheet... 

The validity of the Fermi liquid picture is concluded from a comparison of the effective masses on the fourth pillow-shaped sheet as given in table 2. From the large linear specific heat the renormalized band scheme deduces a characteristic energy kT 10 K which in turn implies heavy masses of the order of w / w 100. This value was confirmed by experiments (Albessard et al., 1993 Aoki et at, 1993 Tautz et al., 1995) where the ijr orbit vnth m /m 120 was observed. The corresponding Fermi surface cross section is in agreement with estimates from the renormalized band theory. This proves that the heavy quasiparticles...

The two faces created are then attached together along all four sides, and an isolating thread is used to hold the three-dimensional shape also called pillow shape as shown in Fig. 23.3. The transmission channel is formed using a mbe-like stmcture made from nonconductive threads, and a single conductive thread coming from the electrode is inserted in the tube-like stmcmre (Begriche, 2015). 

A nonuniform pillow-shaped expansion with open structure, such as potato cubes produced by microwave-enhanced spouted bed drying, restructured blue honeysuckle snacks containing starch produced by MWVD, and microwave-expanded imitation cheese (Arimi et al, 2008 Yan, 2011 Liu et al, 2009).
