    • 583,145. Slicing-machine sharpeners. POWER, P. B., and JOLLY, T. Oct. 5, 1944, No. 19110. [Class 60] [Also in Group VI] A sharpener for a rotary knife 25 comprises a block 61 with pin 62 carrying a swivel head 63. A spindle 64 therein carries a pair of sharpening wheels 65, 65a. The swivel head 63 is held by two springs 66, 66a. By swinging one spring, for example 66a, about its pivot 67 clear of the swivel head 63, the other spring rocks the swivel head about the pin 62, thereby bringing wheel 65 in contact with the knife. Swinging the other spring 66 aside causes the other wheel 65a to contact the knife. The sharpening device can be located out of the way under its base plates 60 and inside an opening 75 covered by a closing plate 76 so that it is free from grease &c. To effect this, the sharpener is first slid to the right until the grooves 68 are disengaged from the casing, then turned over and slid back through the opening 75 in the casing. The opening 75 is closed by a back plate 76 which projects up from the base plate 60 when the sharpener is in the position of use but projects down from the plate 60 within the opening when out of use.

    • Maize gluten or like starch-containing prolamine is treated to render most or all of the starch content water-soluble, and the said starch content extracted with an aqueous medium. Zein may then be extracted from the prolamine residue with an aqueous alcoholic medium. Gluten meal may be treated in aqueous suspension with a hydrolysing agent such as hydrochloric acid or an enzyme preparation, e.g. malted barley extract. The protein residue is dried and extracted with aqueous alcohol to give a zein solution which may be treated with decolorizing carbon, filtered, and concentrated. The initial meal, the protein residue or the zein solution is freed from oil by extraction with a solvent such as toluene or separation of zein and removal of oil may be effected simultaneously using water, alcohol, and an oil solvent. Stable solutions are obtained. Salts or reagents improving stability such as formaldehyde may be incorporated. In examples, maize gluten is heated in suspension in water containing hydrochloric acid or sulphur dioxide for 3 hrs. at 100 DEG C. or for 50 mins. at 30 lbs. pressure, or with malt barley extract for 2 days at 74 DEG C., the product filtered, and the residue washed, dried, ground, extracted with toluene, dried, and extracted with methylated spirit at 60 DEG C.

    • 571,721. Automatic guns. BAKER, P. Oct. 17, 1941, No. 10484. [Class 92 (ii)] A cocking and reloading handle device for use with gas-operated guns having a piston-rod G and return spring K enables charging or jam-clearing operations to be effected without fully stressing the return spring. Fig. 4 shows the parts in the cocked or ready-to-fire position with the cocking handle D and its support C, which forms the rear abutment of the return spring, locked to a projection Q on the gun body. On release of the sear F from a floating bent A on the rod G, the post H moves forward to lock the breech block P and fire the cartridge S. The floating bent then attaches itself by a spring arm B to the support C. The gun then loads and fires normally until the trigger E is released to engage a bent M and stop the fire in the breechopen position. To use the cocking device, the handle D is raised from its locking recess Q and the parts moved without stressing the return spring to the position shown in Fig. 2, a guard C' preventing the sear F engaging the bent M. The parts are then moved forwardly to load the cartridge S from the magazine and, the handle D being again locked against a slight pressure of the return spring, the position shown in Fig. 4 is reached with the floating bent A engaged by the sear F.
