Abstract: 1,037,682. Grippers for lifting articles. MOLINS ORGANISATION Ltd. Sept. 6, 1962 [Sept. 8, 1961], No. 32341/61. Heading B8H. The jaws 10, 11, Fig. 1, of a device for gripping and lifting irregularly shaped articles are provided with members 29 which are displaceable to a limited extent to compensate for the irregularities in the load. The gripper is rotated about an axis A-A by rams 5, 6 which operate a rack and pinion gear. The jaws 10, 11, which are attached to a member 17 by links 20, 21, are rotated about an axis B-B by rams 12, 13 (not shown), and closed by rams 22. The gripping heads are attached to the rod 46 of a piston 47, Fig. 3, which moves in an hydraulic cylinder 48. Conduits 52, 57 interconnect the cylinders through valves 53-56 and 58-61. If one of the rods 46 is moved to the left in Fig. 3 by contacting a load, fluid displaced from the left-hand side of the piston passes into the other three cylinders and moves their pistons to the right. This movement of liquid continues until all the members are gripping the load with equal pressure. Any of the gripping members may be isolated by closing appropriate valves. A pressure sensitive element which prevents further closure of the jaws may be incorporated in the conduit 57 to limit the pressure which can be applied to a load. In a further embodiment the jaws may be either fixed, or move towards each other in finite steps, the gripping members being moved towards and away from each other by a hydraulic ram which acts on all of them simultaneously.

Title: Production of dried meat
IPC: A23L13/70
Filed: 1958-10-13
Abstract: Dried meat which is easily cooked to a product having good odour and taste is obtained by treating the raw meat with a tenderizer, e.g. a proteolytic enzyme, embedding the meat in fat or a similar substance such as paraffin wax, heating in vacuo to remove water, and then removing the surplus fat or the like. Other additions to the meat may be sodium chloride, sodium glutamate, a fat antioxidant, an antibiotic.  The meat is exemplified by beef, veal, pork, chicken and fish, and is not restricted to muscle tissue.  The product is of particular use for soup preparations such as preserves of oxtail soup, pea and pork soup, fish bouillabaisse, mutton-containing scotch broth.  An example is concerned with soaking small pieces of beef for 10 minutes in a salt, papain and glucose solution, draining the meat and freezing it, incorporating molten fat, stirring the fat and meat for 2 1/2 -3 hours at 80 DEG  C. under a reduced pressure of 10 mm. of mercury to inactivate the papain and evaporate water, and then removing fat either by decanting, followed by centrifuging or by pressing.

Abstract: 1,253,794. Transistor gating and amplifying circuits. INTERNATIONAL BUSINESS MACHINES CORP. 7 July, 1970 [10 July, 1969], No. 32801/70. Heading H3T. A gating circuit and sense amplifier includes amplifiers 23, 24 receiving complementary inputs on lines 16 and having high impedance outputs 26, 27, which are connected both to an output circuit such as T33, T34 producing twice the input amplitude and also through respective windings 30, 31 to a voltage source V cc , the windings being by-passed (by T40, T41) when it is required to block the output. T40, T41 are turned on by a timer 18 to block the sense amplifier output when an inhibit pulse on lines 17 is sent (by a driver 12 controlled also by the timer 18) to a memory core line 10. T40 and T41 are turned off by the timer 18 when it is desired to sense a read-out pulse from the line 11 through cores 10, this pulse being very much smaller than the inhibit pulse (56, 52, Fig. 3, not shown). Diodes 21, 22 which protect amplifiers 23, 24 by blocking the inhibit pulse, are conductive over the range of the read out pulse which produces opposite voltage swings at the collectors of T72, T74 due to the impedance of the inductances 30, 31. The transistors T33, T34 drive a common output 35 when a stroke pulse on diode 63 goes positive; and a clamp diode 64 limits the negative voltage swing of the output. Capacitor and resistor 75 and 76 couple the feedback circuits of the two amplifiers 23, 24 for common mode rejection. When inductors 30, 31 are started by T40, T41 the collectors 26, 27 of T72, T74 are clamped to V cc .
