Title: Peristaltic pump
IPC: F04B43/00
Filed: 1975-06-20
Abstract: 1510814 Peristaltic pumps E MALBEC 20 June 1975 [25 June 1974] 26321/75 Heading F1U A peristaltic pump comprises a tube 8 wound at least once around axles 5 of wheels 4 which are mounted in radial slots 6 of a rotor 7, the tension in tube 8 serving to urge the wheels 4 into contact with a power driven shaft 2 so that rotation of shaft 2 rotates wheels 4 which thus orbit round the shaft 2 due to the frictional rolling contact of axles 5 with tube 8, and the axles thus sequentially compressing successive portions of tube 8 so as to pump fluid from inlet A to outlet R. The ends of tube 8 each extend through a hole 10 in a support 9, a projection 8a of the tube serving to hold it on the support under tension. This tension can be varied by having a plurality of projections 8a, and the volumetric capacity can be varied by changing the tube diameter in which case a different sized hole 10 in each support 9 is used.

Title: Improvements in or relating to paper coating machines
Filed: 1953-09-25
Abstract: 741,970. Coating paper webs. PAPER PATENTS CO. Sept. 25, 1953, No. 26455/53. Classes 96 and 140. A web of paper W is coated by a main roll 17 and, optionally also on the other surface by a main roll 78, the roll 17 being mounted on a frame 14 pivoted at 12 and carrying a subframe 21 pivoted at 22, and carrying a transfer roll 36, a metering roll 28, and a back-up roll 26, the rolls 28 and 36 being pivoted at 32 and 42 respectively, on the sub-frame ; all pivots being slightly off-set from a vertical line through the centre of gravity of their total respective loads so that on withdrawal of applied pressure (e.g. through failure of the mechanism), the roll 17 tends to move away from the paper W, and each roll tends to be spaced away from its adjoining rolls sufficiently to allow for cleaning &c. The pressure-applying mechanisms for the frame 14 and sub-frame 21 are as illustrated, the inter-roll pressures of the auxiliary train 19 being adjusted by introducing oil into cylinders 47 until the roll 26 nearly touches the roll 28, whereupon air is supplied'through inlets 58 to diaphragm assemblies until those rolls contact each other with the required pressure. Oil is then introduced into cylinders 98 so that the main frame turns clockwise, and final adjustment of the coating roll pressure is effected by supplying air to a diaphragm assembly 99, in which position very little of the weight of the roll assemblies acts against their pressureapplying mechanisms. Coating mixture is then supplied through a pipe 30 to the nip between rolls 26 and 28, unused mixture being recirculated by a pipe 40. A similar arrangement provides for coating the opposite surface of the web W.

A voltage-controlled change-over switch, particularly for selecting coarse or fine synchro control in a navigation system comprises a circuit arranged to control a pair of two-diode gates in such a way that two pairs of input terminals are respectively connected to output terminals depending whether or not the control voltage is above or below a predetermined level. As shown, the A.C. control voltage at et is rectified at D 1  and fed to a Schmitt trigger comprising transistors Q 1 , Q 2'  When the rectified output from D 1  is above a predetermined threshold, Q 1  is saturated so that Q 2  and Q 4  will be off and Q 3  on. The collector voltages at Q 3 , Q 4  arrange that diodes D 2 , D 3  will be off and D 6 , D 7  on, so that input terminals e 2  are effectively connected to the output terminal e 0 . The conductive states of all the components mentioned become reversed when the voltage from D 1  is less than the threshold, so that input terminals e 1  are then effectively connected to e 0 .

Abstract: 1429846 Storage cells WESTERN ELECTRIC CO Inc 7 June 1973 [9 June 1972] 27181/73 Heading H3T In a memory apparatus including a plurality of memory cells, each cell 12 comprises a bipolar transistor 32 and a field effect transistor 30 whose emitter and source electrodes constitute respectively the input, output terminals 14, 16 of the cell, the collector and gate electrodes of 32, 30 being coupled together and to a capacitance storage C and the base of 32 being coupled to the drain of 30 such that, in operation, binary information stored in the cells is non- destructively readable. A plurality of cells 12 are connected at each cross-over junction of word lines 18 and digit lines 20 coupled to control circuits (22, 24, Fig. 1, not shown) for the writing in or read out of a bit of information into or from each cell. In operation, a "1" bit is written into a cell by applying equal amplitude pulses along lines 18, 20. The source gate path of FET 30 becomes forward biased and the capacitance C charges up to a high level, the voltage pulse at terminal 14 preventing conduction of transistor 32. For reading out a "1", a lower amplitude pulse is applied along word line 18 with a reference or zero potential applied to the digit line. None of the transistors 30, 32 conduct and an output at the reference level is applied to conduction detectors (26, Fig. 1, not shown). A "0" is written in by applying the high amplitude pulse on word line 18 only so that transistors 30, 32 are driven into conduction and the charge on C falls to a low level. When a "0" is to be read out, a low amplitude pulse is applied on word line 18 and a high amplitude pulse is derived on line 20 as transistor 32 is fully conducting. Transistors 30, 32 are chosen to be complementary so that for a P channel FET, an NPN transistor is chosen.
