Hand press

In all the foregoing cases, the percentage of aldehyde or ketone is so high that the estimation by the above processes can be sufficiently accurately carried out on the original oil. With such oils as lemon, orange, hand-pressed lime, and citron or cedrat, however, the proportion of aldehydes is so small that it is not possible to satisfactorily determine it directly on the oil itself by absorption processes, and a preliminary concentration of the aldehydes in the oils by carefully fractionating out the hydrocarbons in vacuo has therefore been proposed by Burgess and Child who recommend the operation to be carried out as follows —... 

By this process lemon oils are found to contain some 2 5 to 3 per cent, aldehydes, hand-pressed lime oil 8 per cent., citron or cedrat oil 4 per cent., and orange oil 0 75 to 1 per cent, but more recent work has shown that these results are somewhat too low, due probably in part to some of the aldehydes distilling over with the terpenes, and for oils containing only a small percentage of aldehydes, a volumetric method, such as the hydroa lamine process, as modified by A. H. Bennet is much to be preferred, as being both simpler and more rapid to carry out, and also. more accurate.

A chemist needed isopropyl ether. He found a pint glass bottle. He unsuccessfully tried to open the bottle over a sink. The cap appeared to be stuck tightly, so he grasped the bottle in one hand, pressed it to his stomach and twisted the cap with his other hand. Just as the cap broke loose, the bottle exploded, practically disemboweling the man and tearing off several fingers. The victim remained conscious and, in fact, coherently described how the accident happened. The man was taken to a hospital and died within 2 hr of the accident of massive internal hemorrhage.

To determine built density (BD), extrudates or Hand Press Texturized products were dried to 5-7% moisture, and ground. Product passing through a U.S. No. 4 Sieve but retained on the U.S. No. 6 Sieve, was filled in 100 ml volumetric flasks, and tapped lightly for 20 times. Weight of the 100 ml sample was determined, and the built density was then expressed as grams per liter. 

FTIR Microspectroscopy.3 A microscope accessory coupled to a liquid-nitrogen-cooled mercury-cadmium-telluride (MCT) detector can be used to obtain an IR spectrum. This is possible in both the transmission and reflectance modes. Several beads are spread on an IR-transparent window (NaCl, KBr, diamond) and possibly flattened via a hand-press or a compression cell. The IR beam is focused on a single bead using the view mode of the microscope. The blank area surrounding the bead is isolated using an adjustable aperture, and a spectrum is recorded using 32 scans (<1 min). A nearby blank area of the same size on the IR transparent window is recorded as the background. 

Treatment of pulp with pectolytic enzymes has two additional benefits. Free-run juice is released more readily from the pulp and overall juice yield is increased. Studies with heated Concord pulp containing cellulose fibers have shown that from 1000-gram portions of pulp, free-run juice obtained 5 min after placing the pulp on an 8-mesh screen was increased from 337 ml for controls with no enzyme to an average of 387 ml for lots containing pectolytic enzymes (at a concentration equivalent to that used in commercial operations). This represented an increase of 15% in free-run juice. Total yield, combining both free-run and hand-pressed juice, increased by 3%. (Equivalent yield on a commercial basis would have been 193.6 gal/ton.)...

He moved towards the throne and stood upon the costly carpet. She took his hand, pressed it tenderly to her heavenly breast, and touched his shield. His armour rang, and a pervasive strength re-vitalised his body. His eyes flashed, and his heart could be heard as it beat against his breastplate. The beautiful Freya seemed happier, and the light streaming from her grew more intense.

Bare et al. (2006) described two cell designs, one for transmission XAFS and one for fluorescence measurements, whereby all of the critical components could be purchased commercially, with little machining required. The designs are simple, robust, and relatively low in cost. The basis of the designs is a quartz tube with windows fabricated from an appropriate material. The tube is heated by a clamshell furnace. The catalyst powder (with or without diluent) is hand-pressed into a quartz sample holder that is inserted into the quartz tube. Thus, a spectroscopically uniform sample is obtained without the high pressure compaction that is necessary to obtain a self-supporting wafer. The cell has been operated at temperatures from 80 to 1373 K, but the maximum working pressure is only approximately 1 bar.

Of the three techniques, the PUF roller most closely approximates the human hand press in the quantities of pesticide residues collected per unit area of surface sampled, although it collects several times as much as the dry palm of the hand. The pliable foam sampling material, especially when wetted, more closely resembles human skin than the cotton fabrics used by the drag sled and California roller. However, since the transfer rates for the latter two devices are much higher than that of the PUF roller, they are less prone to yield non-detectable results in the field. 

For sample collection, the hand was pressed ten times on the carpet, progressing from one end to the other of a 10-cm x 100-cm area framed by the template (total area sampled, 640 cm ). The PUF roller was used to sample adjacent areas of similar size. After pressing in each of three areas of the carpeted room, the hand was carefully rinsed with 70 mL of pesticide-quality 2-propanol, which was collected in a clean sample bottle. Only one hand press was performed per day.
