Filed: 1951-08-11
Abstract: 777,922. Stacking-machines. SUTCLIFFE, SPEAKMAN &. CO., Ltd. Dec. 15th 1954 [Aug. 11, 1951], No. 36260/54. Divided out of 777,921. Class 94(1). A mechanism for moving a load carrier in steps includes an arm or arms 4 Fig. 1, which can be moved into and out of engagement with the load carrier 1 and swung through an arc. As illustrated two arms 4 serve to move a wheeled pallet 1 loaded with double rows of bricks as described in Specification 777,921. As each double row of bricks is pushed onto the pallet the pallet is moved through the width of a double row by a pair of arms 4 which engage in notches 5 on opposite sides of the pallet and are swung about pivots on arms 8 by connecting links 34 operated by cranks 32. A pneumatic ram 15 then acts through links 12, 8 to raise the levers 4 out of the notches 5 so that they may be returned for engagement with further notches 5. The cranks 32 are operated through a chain 30 and sprocket 27 from a double acting pneumatic ram 19 controlled by a relay valve J. As a double row of bricks on the pallet is completed the end brick operates a microswitch O, Fig. 4, or a suitable cam device, so that a pilot valve K controlling the relay valve J causes the ram 19 to move the lever 4 to move the pallet. At the end of the operative movement of the levers a projection 47 on the shaft carrying the cranks operates a pilot valve L controlling a relay valve H which causes the ram 15 to raise the levers 4. A projection 54 on a shaft in the linkage by which the levers 4 are raised then operates a pilot valve M to cause the relay valve J to retract the piston of the ram 19 and thus return the levers 4 : at the end of this motion the projection 47 operates a pilot relay N which causes the relay valve H to retract the piston of the ram 19 and thus lower the levers 4 into engagement with further notches in the pallet. A crank 51 fast on the same shaft 25 as the sprocket wheel 27 is connected to the piston rod of a hydraulic cylinder 59 which is connected through throttle valves 65 to a liquid reservoir 64 to serve as a dash-pot. Further throttle valves may be arranged in the pneumatic valves H. J. K. L. Adjustable stops (not shown) limit the movement of the crank 27 and the connecting rods 34 are connected to the levers 4 by clamps 35 adjustable along the length of the levers so that the stroke of the levers may be adjusted. A roller carried by a spring biassed lever 38, Fig. 1, engages in the notches of the pallet to hold it against movement while the levers 4 are being retracted. The relay valves H, J, K, L, illustrated have bleeds bored in their pistons so that they can be controlled by pilot valves K, L which serve only to connect one of the working spaces of the relay valve H, J, K, L to exhaust (or in an alternative arrangement to pressure). In an alternative construction, however, the pistons of the relay valves have no bleeds and the pilot valves K, L connect opposite ends of the relay valve to pressure and exhaust.

Abstract: 1,029,550. Cooling meat and fish. GORDON JOHNSON CO. Sept. 16, 1963 [March 18, 1963], No. 36319/63. Heading F4H. [Also in Division A2] A method for the preservation of meat and fish comprises quick-chilling the meat or fish to a temperature in the range 33‹ to 40‹ F. thereby to remove body heat, deep-chilling to such a temperature that the meat or fish tempers to a temperature in the range 28‹ to 32‹ F., and thereafter storing the meat or fish at a temperature in the range 28‹ to 32‹ F. Under preferred conditions of operation, the quick-chilling of the meat or fish is accomplished prior to the commencement of substantial spoilage and before appreciable physical and chemical changes therein, the quickchilling is effected by tumbling in a bath of low temperature water, the meat or fish is drained on leaving the water bath and is then packaged in a plastic bag or on a tray in order to retain the residual moisture and to prevent contamination and adulteration. The deep-chilling is carried out by immersion in or spraying with a refrigerated solution, by a blast of air at temperatures ranging from - 20‹ to - 40‹ F., or by subjecting the meat or fish, while being advanced along a belt or screw conveyer, to a shower of released carbon dioxide gas. In the case of poultry the final temperature reached should be such as to cause the water content of the poultry to freeze without freezing of the tissues and body fluids. Poultry packaged in plastic bags may be stored in shipping containers made from wood or cardboard. Meat and fish: ready-to-cook poultry such as chickens, turkeys, ducks, geese and guinea fowl, the meat of cattle and calves, sheep, swine, goats, game, wild animals and fish, and edible products derived from their carcasses.
