Title: Improvements in and relating to the separating of sheets from a pile and the feeding thereof to working machines
IPC: B65H3/56
Filed: 1936-11-30
Abstract: 465,866. Feeding sheets. SPIESS, G. Nov. 30, 1936, No. 32823. Convention date, Nov. 30,1935. [Class 100 (i)] In a sheet-feeding machine of the kind in which the sheets are separated by means of a suction or like separator acting on the rear edge of the pile 1 and are directed by guides 6 to feed rollers 3, 4, the front edges of the sheet are raised by means of movable pile guides, which prevent double feed and assist the transfer of the separated sheet to the feed rollers. As shown in Fig. 1, the pile guide 8 is carried by parallel levers 9, 10, and is raised at intervals by a cam 13 acting on the arm 12 of lever 9. A roller 15 is fitted at the top of the guide 8, or its upper end may be curved in the direction of the rollers 3, 4, and while the guide is raised the sheet may be acted upon by a reciprocating suction device engaging the front edge of the sheet. The guide 8 may be replaced by a pair of discs 16, Fig. 3, rotating in opposite directions and formed with flat surfaces over which the sheet is fed before the circular parts of the discs raise the front edge of the sheet 2. In a further modification, Fig. 6, guide rails 8 are connected by a transverse strip 20 to which are secured strips 21 in a grid-like manner, and an air blast conduit may be arranged to deliver air blasts through top openings 23 and side openings 24. In a further modification, Fig. 7, the curved guide rails 27 forming pile guides are reciprocated vertically and carry rollers 15 which co-operate with positively driven feed rollers 26 disposed above the rollers 15.

Abstract: 1356347 Transistor switching circuits FUJITSU Ltd 16 July 1971 [31 July 1970] 33626/71 Heading H3T A thresholding circuit comprises a differential amplifier, a transistor squaring stage 3 and an impedance reducing output stage 4, the squaring stage being held out of saturation by a feedback transistor 16 having its output path connected between the circuit output and the input of the squaring transistor. When transistor 3 is driven hard the emitter of the feedback transistor 16 is held negative of the collector of the squaring transistor by the diode drops of transistor 4 and diode 17 and this holds the collector-emitter potent voltage of transistor 3 above the saturation level. Zener diode 8 has the same voltage drop as diode 11 and as the base-emitter voltage drop of transistor 16 is equal and opposite to the drop across diode 18 the output terminal is maintained at earth potential. When the drive for transistor 3 is removed a potential derived from the output by a potentiometer 20 exceeds the voltage applied by a Zener diode 8 to the base of a transistor 8 whereupon the transistor conducts and clamps the output voltage at a level which is independent of supply voltage variations. It is stated that field effect transistors may be used and the common emitter resistor 7 may be a transistor.

IPC: G01K7/02
Filed: 1956-11-05
Abstract: 835,564. Measuring temperature. SMITH & SONS (ENGLAND) Ltd., S. Nov. 5, 1957 [Nov. 5, 1956], No. 33701/56. Class 40 (1). [Also in Group XXXVI] A thermocouple measuring system has a temperature-sensitive network adjacent to the cold junction to develop an E.M.F. to compensate for variations in the cold junction temperature, this E.M.F. being added in series with the thermocouple voltage and passed to an indicator having a non-linear scale. Fig. 1 shows a circuit suitable for measuring the temperature of gas flow in an aircraft gas turbine installation. A number of thermocouples 1 in parallel, are connected by short leads 2, 3 of the same material to the cold junctions 19, 20. The Zener diode 6 supplied with D.C. from 7, 8 provides a stabilized voltage between the points 9, 10 across a bridge the output of which is in series with the thermocouple voltage. The resistors 13, 14 have a high temperature coefficient so that the bridge output depends on the ambient temperature, which is the same as the cold junction temperature. A thermistor 22 is included to minimize variation of output impedance with temperature and thus preserve accuracy of calibration of the meter 26. The latter has a number of hair springs and corresponding fixed stops so that the sensitivity has different values for different parts of the scale. By this means the central part of the scale can be made more open over the range of greatest interest, e.g. 400-800‹ C. The voltage 7, 8 can be taken from the aircraft D.C. supply or from a transformer and rectifier from the A.C. supply. In a modification (Fig. 2, not shown) a lower series impedance is obtained by connecting the tops of the resistors 12, 13 to two separate Zener diodes each (with its series resistor) joined across the D.C. supply.
