Title: Sheet cutting
IPC: B21D43/28
Filed: 1973-11-10
Abstract: 1406551 Feeding sheet material MOELLER & NEUMANN GmbH 10 Nov 1973 52270/73 Heading B3W For cutting a predetermined length from a sheet 22 advanced through a transverse shear 1, 2 on to a tiltable table 5, the actual length downstream of the shear is measured and compared with the predetermined length. If an error signal occurs indicating that the actual length is shorter than the predetermined length, the sheet is clamped to the table, e.g. by magnets 23 moved against the underside of the sheet by hydraulic cylinders 25, and the table is displaced longitudinally away from the shear by cylinder 18 until the control length equals the predetermined length. The shear is then actuated. Measuring rollers 4 are supplemented by rollers 28 for use when the trailing edge of the sheet has left the rollers and before the predetermined length is reached. The table 5 has drivable rollers 11 which take over the sheet feeding from two laterally spaced pairs of drive rollers 3 and are stopped when the sheet is clamped to the table 5. Tie rods 10 moving in synchronism with the upper blade holder 1 pivot levers 9 to tilt the table end nearer the shear downwardly, the other end running on rollers 6 on a track 7. A section 13 of a delivery table bridging the gap between the tiltable table 5 and a fixed section 12 is downwardly pivotable by cylinders 17 to allow the longitudinal displacement of the tiltable table 5. The tiltable table is also moved longitudinally to allow scrap lengths to fall on to a shoot 20. A mechanical drive may be provided in addition to the hydraulic cylinder 18, both being disconnectible to allow the other to operate alone. The supply of pressure for the longitudinal displacement of the table may be automatically stopped when the predetermined feed length is achieved.

Abstract: 1409895 Transistor gating circuits; automatic exchange systems; negative impedance repeaters LICENTIA PATENT-WERWALTUNGS GmbH 13 Nov 1972 [12 Nov 1971] 52279/72 Headings H3T H4K and H4R A gating circuit suitable for use in a telephone one or two wire cross point switching arrangement, Fig. 3 (not shown), comprises a negative impedance arrangement, e.g. cross coupled transistors Ts1, Ts2, Fig. 4, which compensate for attenuation in the signal path when the gating circuit is in its conductive state.

Resistor R0 in the biasing circuit may be an FET, and Ts1, Ts2 may be a single four electrode device. Two similar circuits may be used in a balanced arrangement, Fig. 5 (not shown).

Title: Optical scanning system
Inventor: STEWART DAVID JOHN
IPC: H04N3/08
Filed: 1965-12-09
Abstract: 1,127,178. Local-copying. K. S. PAUL & ASSOCIATES Ltd. 9 Dec., 1966 [9 Dec., 1965], No. 52419/65. Heading H4F. The Specification describes a local copying system whereby a flat opaque or transparent object 12 can be photographically reproduced at 19, with any desired degree of enlargement or reduction. A gas laser 1 produces a continuous narrow light beam which passes via an intensity modulator 3 to an oscillating mirror 4 moving in such a manner that the reflected light beam describes a raster scan. The scan is focused on an intermediate plane 6 by a lens system 5 comprising the output half of a double-gausse lens. Part of the scan is deflected by semi-reflector 11 on to the object 12, the focusing being carried out by lens 9. For an opaque object the light reflected by the object is integrated in cavity 15 and detected by photo-cell 16. For a transparent object the light passed by the object is integrated in cavity 13 and detected by photo-cell 16. The part of the scan passing through micron 11 is focused by lens 10 on to the photosensitive means at 19, via a possible screen 20. Modulator 3 therefore modulates the light beam under the control of the output of a computer such that the object is correctly reproduced at 19. The signal produced by photo-cells 14 or 16 must therefore be corrected for this modulation. The modulation is therefore detected by a photo-cell 17 fed by a semi-reflecting mirror 18 and its output fed, together with that of the photo-cells 14 and 16, to the computer. For focusing adjustments and for the setting of the desired degree of enlargement or reduction by lenses 9 and 10, a light source 21 and mirror 23 are provided.

Title: Improvements relating to shift registers

IPC: G11C19/18
Filed: 1968-11-08
Abstract: 1,239,948. Shift register. FERRANTI Ltd. 3 Nov., 1969 [8 Nov., 1968], No. 53001/68. Heading G4C. [Also in Division H3] A shift register operates as a three-phase static shift register below a certain pulse repetition rate and as a two-phase dynamic shift register above that repetition rate. The register comprises a series of binary cells, each cell being connected to its neighbour by a first switch S1, each cell comprising two inverters I 1 ,I 2  joined by a second switch S2 and a third switch S3. The inverters and switches are made of insulated gate field effect transistots (IGFET'S), possibly in integrated circuit form. Each switch S1 S2, S3 is actuated by a corresponding pulse train # 1 , # 2 , # 3  and the magnitude of # 3  depends on the repetition rate of one of the trains # 1 , # 2 , by causing the charging and discharging of a capacitance (Fig. 3, not shown). When the repetition rate is relatively low each cell acts as a bi-stable using the two invertors. However, at a threshold frequency, the capacitance between the gate and source of an IGFET in each inverter can store a bit. The switch S3 becomes unnecessary and at this frequency the magnitude of # 3  is arranged to be insufficient to switch S3 and the register operates as a twophase dynamic device.

Title: Arrangement for the monitoring of intermediate repeaters in a carrier-frequency transmission installation
IPC: H04B17/40

Abstract: 1,145,038. Unattended repeaters. FELTON & GUILLEAUME CARLSWERKE A.G. 24 Nov., 1967 [9 March, 1967], No. 53509/67. Heading H4R. In an arrangement for monitoring unattended repeaters in which a test signal of a frequency allotted to each repeater is extracted and fed back to the line changed in frequency, as in Specification 828,061, the test signal is selected by a filter formed by a crystal Q and the high impedance winding W of a transformer of which the low impedance winding is part of the highpass T-network 6 of the current supply circuit. The crystal filter thus has a low input impedance in relation to the characteristic impedance of the line. A resistance R, and if desired, an LC filter may be provided in the input to the frequency-converter U, which may double the frequency. The transmission characteristics of the repeater may be observed at the end from which the test signals are sent, and the noise may be measured at the other end.

Suitable components, e.g. ethylene, are recovered from gas mixtures containing them, e.g. coke oven gas, by passing the gas mixture first through a layer of active coal carbon and then through a layer of active wood carbon, e.g. in a fluidized bed, on which the ethylene is selectively adsorbed. The active coal carbon, which is suitably obtained by steam treating a coal, adsorbs the higher alkenes and may be used as a fuel after use, while the wood carbon, being more expensive, is regenerated by desorbing the adsorbed ethylene with steam.

Abstract: 1401825 Hydraulic control circuits WABCO WESTINGHOUSE GmbH 24 Nov 1972 [24 Nov 1971] 54383/72 Heading F1P In the circuit shown with a control lever 11 in the position illustrated, oil from a reservoir 1 is circulated by a pump 2 through a line 5, passages 7, 8 and grooves 20, 19 in plungers 18, 17 and a line 22 to the reservoir. Tapered flow valves 32, 33 are equally spring loaded by springs 30, 31 to close ports 34, 35. To move a piston in a cylinder 43 to the left the lever 11 is moved in the direction of arrow I. Grooves 19, 20 are moved out of alignment with the passages 7, 8 thereby blocking the return to the reservoir. The fluid-pressure now rises until it reaches the limit set by a valve 46. Spring pressure on the valve 32 is reduced when the plunger 17 moves upwards and pressure on the valve 33 is increased by downward movement of the plunger 18. When the pressure on valve 32 drops below the circuit pressure the valve 32 opens, causing a pressure drop in line 39 as a result of flow through a diaphragm valve 40. Pressure in a line 41 remains the same so the piston in cylinder 43 is displaced. If the lever 11 is moved in the direction II the piston will move in the opposite direction. Centering springs in the cylinder 43 return the piston. Four valves may be controlled by moving the lever 11 in two orthogonal directions.
