IPC: F04F5/52
Filed: 1969-10-02
Abstract: 1,237,039. Fluid-pressure servomotor systems; fluidic circuit elements. FOXBORO CO. Oct.2, 1969 [Nov. 1, 1968], No.48431/69. Headings G3H and G3P. A bellows 20 forming part of a servomotor system has a connection 26 with a Venturi device 13-16 which applies negative or positive pressure to the bellows according to the back pressure generated in line 25 by movement of nozzle 22 relative to deflector 23 by the bellows. Line 27 provides the output pressure from the system, and a screw 28 acting through a linkage 12 adjusts the datum position of the deflector which is indicated by a pointer 31. Fluidic circuit elements.-The Venturi device is formed as a slot in a lamination 37 Fig. 5 sandwiched between end-plates 35, 38 to form a circuit element approximately one inch long and one sixteenth of an inch in thickness.

Title: Solid state photosensitive device
IPC: H01L31/00
Filed: 1964-11-30
Abstract: 1,083,287. Photoelectric devices. WESTINGHOUSE ELECTRIC CORPORATION. Nov. 30, 1964 [Dec. 12, 1963], No. 48557/64. Heading H1K. A photo-cell comprises a non-superconducting layer in which hot electrons are generated by incident photons and a thin insulating layer through which they tunnel to a second non- superconducting electrode. Typically the lightsensitive layer is aluminium evaporated on a transparent substrate, the insulating layer aluminium oxide formed by oxidizing the aluminium and the second electrode an evaporated layer of silver, gold or platinum. To provide a device with voltage and power amplification a second thin insulating or N-type semi-conductor layer of higher resistance than the first layer is deposited between the second electrode, chosen to be thin enough to allow the hot electrons to penetrate, and a third electrode. In another modification a second layer of P-type semi-conductor, e.g. cadmium telluride with built-in trapping levels is used instead. This gives current amplification provided that the trap recombination time exceeds the whole transit time across the layer.

Title: Circuit arrangement for producing a definite number of pulses
IPC: H03K3/64
Filed: 1964-12-02
Abstract: 1,038,851. Transistor circuits. TELEFUNKEN PATENTVERWERTUNGSGESELLSCHAFT m.b.H. Dec. 2, 1964 [Dec. 3, 1963], No. 48975/64. Heading H3T. A transistor circuit for the production of a definite number of pulses by means of a pulsing relay has the relay coil 1 arranged in parallel with a capacitor C1 in the collector circuit of the transistor 5, with a further capacitor C2 in series with a break contact of the relay connected in a feedback loop between the collector and the base. When a switch 4 is closed to apply a voltage across the circuit current flow charges capacitors C1 and C2 and the current flow through the relay winding increases until the relay is operated. At this point capacitor C2 is either discharged slightly through resistor R9 by means of relay contact R8 or, if no resistor is present the capacitor is disconnected from the circuit. This causes current flow to cease through the transistor and capacitor C1 discharges through the relay winding until the current drops such that the relay releases and current again flows through the transistor causing the operation to commence. This continues until capacitor C2 is fully charged and prevents the current flow through the transistor. The number of pulses produced by the contact 3 of the relay switching from a positive to a negative potential supply can be varied by altering resistor R9.

Title: Improvements in or relating to metal plate shears
IPC: B23D15/14
Filed: 1964-12-07
Abstract: 1,067,920. Shearing. F. MOELLER and K. NEUMANN, [trading as VERWALTUNGSGESELLSCHAFT MOELLER and NEUMANN]. Dec. 7, 1964 [Dec. 5, 1963; Aug. 17, 1964], No. 49677/64. Heading B3W. In a plate shear the upper blade holder 2 is positioned by hydraulic cylinder assemblies 6, 8, 9 to suit the thickness of the plate to be cut and the lower blade holder 3 is given a rocking motion by hydraulic motors 12, 13 so that the curved edge of the blade rolls along a horizontal plane which passes through the edge of the upper cutter only when the upper cutter is in the position to suit the thinnest material which the shear is intended to cut. The path traversed by the curved edge of the lower cutter is always the same, so that when thick plates are being cut, the edges of the cutters do not overlap, but the depth of cut is sufficient to cause separation of the remainder of the thickness of the plate. Operation.-Fluid from a pump P1 is admitted to the end 12a of the motor 12 until the lower cutter touches the underside of the plate and raises it against the upper cutter to begin the cut at the left-hand side of the plate. Pressure fluid is then admitted to the end 12b of the motor 12, a valve 54 is opened, and the valve 52 closed so that fluid forced out of the end 12a can only pass to the end 13a of the motor 13. As a result the left-hand end of the cutter holder 2 is lowered and the right-hand end is raised. The path of the blade is also controlled by an outwardly inclined guide 20, Fig. 1 (not shown), formed in the left-hand side of the shear frame and a pivotable guide 23 mounted in the right-hand side of the frame and also outwardly inclined. In a first modification, Fig. 8 (not shown), the lower blade is immovable and the upper blade is driven by eccentrics on a shaft journalled in the lower part of the machine and connected by rods to a shaft which passes through the upper cutter holder. This latter shaft is eccentrically mounted in the upper cutter holder and in this embodiment the gap between the cutters is adjusted by rotation of the shaft, to suit the plate thickness. At each end of the upper cutter holder are rollers, one of which runs on a fixed outwardly inclined surface 220 formed on the machine frame, and the other of which runs on an outwardl yinclined surface pivoted to the other side of the frame and able to rotate about its pivot against the action of an hydraulic cylinder. In a second modification. Fig. 9 (not shown), the lower cutter is immovable, the upper cutter is driven by eccentrics mounted in the upper part of the machine, it is guided by one fixed and one pivotably mounted surface and the whole of the upper part of the machine is supported by nuts fitted on four vertical columns, the cutter gap being adjusted by simultaneous rotation of the nuts.
