Punches removing

Upper punch removal/dwell cams The upper punches are loaded and removed from the machine at this location. These cams typically reside directly above the material feeder. In many press designs, the upper punch dwell... 

After pressure appHcation, the top punch is removed and the compact is ejected from the cavity by the bottom punch. The cavity is then refilled and is ready for another charge. This cycle is repeated automatically at a rate that varies with the part and size and the complexity and dowabiUty of the powder. Pressing equipment producing relatively small, simple parts can operate at up to 200 parts/min. Rotary presses with multiple die sets are even faster. Table 5 gives the ranges of pressures used for various materials during die compaction. 

PREPROCESSOR - Modifies the FTAP punch file output for common cause and dependent analyses (conditional probabilities), removes complemented events, and corrects for mutually exclusive events. 

Pressing is carried out within a cemented carbide die between two steel or cemented carbide punches. In order to impart enough mechanical strength to the blank to permit further manipulation without risk, removable organic binders (camphor, natural or synthetic waxes, latex or synthetic rubber, methyl polymethacrylate, polyvinyl alcohol, carboxymethylcellulose, ammonium alginate) are mixed into the powder, dissolved in a convenient volatile solvent. Some of these also act as lubricants thus minimizing the wear on the die. 

Useful with icepick and narrow-deep boxcar scars that are excised with a 1.5-mm punch biopsy and sutured with a 6.0 or smaller suture. Nonabsorbable sutures are preferred to avoid inflammation and must be removed within 5 days. 

The silicon chip reactor was compressed between a top plate, for direct observation of the flows, gaskets with punched holes and a base plate with all fluid connections [13,14]. Thermocouples inserted between the two plates were located next to the micro reactor. A third inlet served for reaction quenching by introducing an inert gas such as nitrogen. Generally, heat removal is facilitated by the special reactor arrangement acting as a heat sink. 

The residue is removed from the leaf surface by shaking the leaf punch sample in an aqueous surfactant solution. This allows for removal of test substance residue from the leaf surface. It does not remove residue absorbed on the plant matrix that extraction and maceration in organic solvents would release. Generally, the extraction with aqueous surfactant is performed using a mechanical shaker for a 10-min interval and is repeated to increase transfer efficiency. 

The rinse water, steam/condensate, and residual agent bypass the AQS and go to the agent collection system. After the agent is removed from the warhead and the warhead has been steamed out, the rocket is rotated 90 degrees to minimize agent leakage from the punch holes. 

This work was done in collaboration with Professor Hiroshi Yoneyama of Osaka University [124], The procedure used to prepare the LiMu204 tubules is shown schematically in Fig. 21. A commercially available alumina filtration membrane (Anopore, Whatman) was used as the template. Alumina is especially suited for this application because of its high porosity, monodispersity of pore size, and the fact that it can be heated to high temperature without degradation. This membrane contains 200-nm-diameter pores, is 60 p,m thick, and has a porosity of 0.6. A 1.5 cm X 1.5 cm piece of this membrane was mounted on a Pt plate (2 cm X 2 cm) by applying a strip of plastic adhesive tape (also 2 cm X 2 cm NICHIBAN VT-19) across the upper face of the membrane. The Pt plate will serve as the current collector for the LiMn204 battery electrode material. The strip of tape, which will be subsequently removed, had a 1.0 cm circular hole punched in it, which defined the area of the membrane used for the template synthesis of the LiMn204. 

Enzyme-Immunoassay. Fish tissue samples for testing were cut into uniform 3mm thick slices with parallel razor blades mounted on a handle. Four discs were then punched out from each slice with a stainless steel borer, 3-mm in diameter, and each disc was placed in a well of a 96-well polystyrene microtiter plate (Flow Laboratories, Inc., Hamden, CT). Samples were washed once with 0.2 ml Tris buffer. After the wash solution was aspirated, each sample was fixed in 0.2 ml of 0.3% H O -methanol fixative for 30 min. at room temperature. Samples were then transferred to clean wells and 0.2 ml of a 1 100 dilution of sheep-anti-ciguatoxin-horseradish peroxidase conjugate in Tris buffer was added to each well. The plate was then incubated at room temperature for 1 hr. The sheep-anti-cigua-toxin-horseradish peroxidase was removed by aspiration, and the tissues were immersed for 5 min. in 0.2 ml Tris buffer. Each sample was transferred to clean wells and incubated for 5 min. at room temperature with 0.2 ml of 4-chloro-l-naphthol substrate. The final steps involved removal of the tissue and addition of 0.015 ml of 3 M sodium hydroxide to stop the enzymatic reaction. Absorbance readings at 405 nm of each well were obtained in the Titertek Multi-skan (Flow Laboratories, Inc., Hamden, CT). 

Pour 4 ml of molten Soln. B onto pre-coated slides (cf. Protocol 4.8.2). Punch wells according to Fig. 4.2 after gelation, and remove residues of agar from the wells. 

The operations of a punched-card calculator are determined by the wiring of a control panel. The panel, in effect, completes circuits between components in the machine so that desired operations are carried out. The panels may be removed from the machine and saved permanently. Thus several differently wired panels may be kept on hand for different types of problems, making it a simple matter to change the functions of the machine. 

After polymerization the polymer sheet is detached from the glass plates and cut into disks using a punch. Disks are washed in methanol for several days and then in 50/50 (v/v) methanol/water overnight to remove unreacted components and the sol fraction. Disks are then dried, first at room temperature for 24 h and then at 50 °C under vacuum for another 24 h. It has been confirmed that further drying steps leads to no measurable change in polymer weight. Elemental analysis of the copolymers reveals that the resulting polymer networks have the same comonomer content as the feed. 

Where wet adhesion was to be measured, discs 31 mm in diameter were punched from the panels and bonded in the same manner, except that all discs were kept water wetted until bonded, and the alignment jigs stored at 100% RH. Specimens were removed and tested with minimum delay to avoid drying out.
