Title: Field effect transistor circuits
IPC: H01L27/07
Filed: 1971-01-14
Abstract: 1314503 Shift register INTERNATIONAL BUSINESS MACHINES CORP 14 Jan 1971 [28 Jan 1970 (3)] 1789/71 Heading G4C [Also in Divisions H1 and H3] A F.E.T. T1 has a capacitor between source and gate, and a control pulse P applied to its source appears at the drain regardless of whether any other input is applied to its gate. The drain pulse is stored on a capacitor CO of a further similar arrangement of a F.E.T. T2 and capacitor; and this stored charge is discharged or not according to whether a data input then turns on T1, thus giving an inversion. Occurrence of a clock pulse # turns on T2 and charges an output capacitance C2 accordingly. A plurality of these stages may be combined in a shift register, Fig. 5, using a four phase clock source for four successive stages, and two control pulse sources P1, P2 to supply the power for charging the gate-source capacitors of respective pairs of stages; P1 and P2 may be # 3  and # 1  respectively. Two such shift registers are effectively combined for apparently two-directional operation (Figs. 8A, 8B, not shown). The capacitor CO of Fig. 2 may be omitted, and the clock pulses arranged to overlap the appropriate control pulses P1, P2 (Fig. 11, not shown) so as to hold T2 conducting during the P1 or P2 pulse to charge the output capacitance (C2) directly. Shift registers using this circuit are also described (Figs. 12, 13, not shown). An output or input stage uses the Fig. 2 (or Fig. 11) circuit and adds a diodeconnected F.E.T. or a Schottky diode across T1 (Figs. 10, 15, not shown) to boost the output.

Title: Method and apparatus for continuously manufacturing cheese
IPC: A23C19/064
Filed: 1964-01-16
Abstract: 1,013,722. Cheese curd. B. E. BUDAHN. Jan. 16, 1964 [May 3, 1963 (2)], No. 2034/64. Heading A2B. In making cheese from slabs of cheese curd in a continuous operation, slabs of curd are milled substantially continuously, the milled curd is conveyed at once continuously away from its point of milling to a tumbling and hooping station, a predetermined proportionate amount of salt is continuously added to the curd as it is so conveyed, the milled curd and salt are tumbled until the salt has coated the curd evenly, the curd and salt are subjected to live steam as they are tumbled, and the salted curd is charged, as it is so conveyed, into containers at the hooping station for subsequent pressing of the curd into cheese. In preferred operations, the milled curd is conveyed to the tumbling and hooping station in a uniform layer of one to two inches thickness, 65-85 lbs. salt are added for each 2,000 lbs. curd, the curd and salt are tumbled for approximately 20-30 seconds, and live steam is released from pressures of about 60 lbs. per sq. in. in such quantities as to maintain the curd at a temperature between 96‹ and 106‹F., preferably 102‹F., while it is tumbled. Curd, milled in a power driven milling apparatus 10 is uniformly deposited by a vibrator 11 upon a rubber belt conveyer 14. Upon reaching the upper end of the conveyer 14, the milled curd discharges through a shoot 37 into a tumbling drum 38 held about a pivot 55a by a link 57 adjustable in position by rotation of a threaded shaft 58. Salt fed from a bin 28 by an auger conveyer 27 operated at a uniform rate, falls through shoots 35 and 36 to be mixed with the milled curds discharged off the conveyer 14. It is arranged that the motor 24 for the auger conveyer 27 operates only so long as a blade 23 is deflected off the vertical position by the flow of the milled curd. In the tumbling drum the salted curd is carried around and is rolled by two sets of blades, Fig. 2 (not shown), and is heated by direct injection of steam supplied through a line 67 when curd is being received within the drum. Escape of the steam from the drum is restricted by an adjustable cover 42. The tumbled and salted curd discharges through a shoot 60 into a hoop 66. A pneumatically operated gate 61 closes when the desired weight of curd has been received in the hoop and opens again after a predetermined period of time allowing for replacement of the filled hoop by an unfilled one.

Jan. 22, 1934, No. 2123. [Class 28 (ii).] In a slicing-machine wherein the substance is fed step by step across a support by a guided substance engager, an auxiliary support is provided to relieve the frictional drag on the main support, the auxiliary support being pivotally and slidably mounted on a guide and the substance engager being pivoted relative to the auxiliary support for use as a clamp or pusher. As shown in plan in Fig. 2, the main support 11 has an upstanding wall 11<a> and the auxiliary support 12 has an upstanding wall 12<a>. The substance engager 16, 17 is carried by a bracket 18 having a boss 20 which is secured to a sleeve 21 slidable on a guide 22 attached to a bracket 10<a> on the reciprocating under carriage. The wall 12<a> of the support 12 is provided with a sleeve 23 which is revoluble on the sleeve 21 but is prevented from moving endwise by the boss 20 and a collar 24. In a modification, Fig. 4, the substance engager is movable relative to the support 12 to occupy either a forward position or a position more remote from the knife. In this construction, the sleeve 21 is provided, along the middle part of its length, with keys 31 to one of which the wall 12<a> is secured at 30, e.g. by welding. The boss 20 has corresponding keyways 32 one of which is open sided at 33, to permit the passage of the part 30. By raising the bracket 18, the keys 31 and the keyways 32 are aligned and the substance engager is then free to be slid along the sleeve 21 to its other position when, owing to the keyways 32 leaving the keys 31, the substance engager may be again swung down to its operative position. The reciprocation and feed of the substance is effected by the handle 19. The main support 11 may be provided with longitudinal ribs to reduce the friction between the supports 11, 12, and the support 12 may be provided with substance-engaging pins.

Title: Improvements in or relating to pumps for viscid substances
IPC: F04B53/14
Filed: 1958-01-22
Abstract: 822,133. Reciprocating pumps. KASTNER, O. M. Jan. 22, 1958 [May 23, 1957; Oct. 4, 1957], No. 2226/58. Class 102(1). [Also in Group XXIX] A piston is reciprocated in a cylinder by hydraulic fluid under pressure and suction acting on one side of the piston while the cylinder space on the other side of the piston acts as a pumping chamber for a viscid substance. The valve controlling the hydraulic fluid and the inlet and outlet of the pumping chamber are actuated by electric switches which are themselves controlled by the position of the piston. Fig. 2b shows one embodiment where the right hand side of the piston 2 moving in a cylinder 1 is the pumping chamber and the left hand side is under hydraulic pressure and suction. In the position shown left hand side is under suction and as the piston continues to move to the left a rod 35, attached to the piston, pushes a member 30 to actuate switch 37 this causes the valve gear controlling the hydraulic supply to feed pressure to the left hand side of the piston and also open the pump outlet valve and close the inlet valve. The piston 2 now moves to the right until a cord 36 tightens and pulls the member 30 to actuate switch 38 when the valve positions of the hydraulic supply and pump are reversed. In a modified form a permanent magnet is attached to the piston which actuates armatures controlling the switches positioned along the cylinder 1. In a further modification the piston presses a spring loaded lever at the left hand end of the cylinder to actuate one switch and the piston then moves to the right until it engages a stop. The hydraulic fluid causes an increase in pressure in the cylinder which moves on diaphragm to actuate the second switch. Two diaphragm actuated switches may be employed and in all cases the switches may be arranged inside the cylinder. Specification 755,677 is referred to.
