Title: Improvements in or relating to the handling of sheets of glass carried on a conveyor
IPC: B23D36/00
Filed: 1963-05-22
Abstract: 1,035,669. Conveyers. COMPAGNIE DE SAINT-GOBAIN. May 22, 1963 [May 22, 1962], No. 20426/63. Heading B8A. Strips of glass of different sizes 4, 5, 6 cut from a sheet 3 on rollers 1 by conventional means A are conveyed in the direction of an arrow f 1  by feed rolls 2. Adjacent a side conveyer 8, with centre axis xy the leading edge 12 of a sheet of glass 12 (Fig. 3) engages a stop 13 on a slide 15 linked by a cable 17 to a slide 16 carrying a contactor 14 so that when the slide 15 is moved by the sheet 11 the slide 16 moves in the opposite direction at the same speed. In the initial position (Fig. 2) the stop 13 and the actuator are a distance e apart, the axis XY bisects the distance e. If the length of the sheet is a the contactor 14 reaches the trailing edge of the sheet 11 when the sheet has moved a-e/2 after engaging the movable stop 13. The transverse centre line at this instant is aligned with the axis xy and as the contactor 14 clears the trailing edge of the sheet it passes a signal to means 10 which may transfer the sheet 11 to the side conveyer 8. Actuation of the means 10 is also controlled by a measuring device consisting of a wheel 25, on a spindle 26, engaging the bottom of the sheet 11 and driving a perforated wheel 27 the holes 28 passing in front of a light 29, the light passing through the holes 28 being received by a photo-electric diode 30 generating pulses amplified by an amplifier 31 and counted by a counter 32. A contactor 24 in the vertical plane containing the axis xy, which also contains the axis of the spindle 26, energizes the measuring means when the leading edge 12 reaches it so that a train of pulses proportional in number to the distance of forward travel of the strip is counted by counter 32. At a predetermined number of pulses (effectively measuring the strip length) a signal is emitted by the counter 32 and if this coincides with the signal from contactor 14 as the trailing edge of the sheet 11 clears it means 10 is actuated to transfer the sheet 11 to the side conveyer 8. When the two signals are not synchronized the sheet 11 is not transferred and continues along the feed rolls 2. Slide 15 comes into contact with a fixed stop 23, the stop 13 is depressed by the conveying force against a spring 22 so that the sheet 11 passes on while slides 15, 16 are returned to their initial position by a counterweight 20. The measuring device 25 to 32 may be set upstream of the axis xy in which case (Fig. 4, not shown) a memory store is provided for the signal from the counter 32. Fig. 5 (not shown) illustrates a modification in which the movable stop 13 and the slide 15 are replaced by a drive from one of the conveyer drive shafts 34. The slide 16 derives its motion from the drive shaft 34 through an electromagnetic clutch 39 operated by the contactor 14 when depressed by the leading edge of the sheet 11 to connect the drive to a drum 36 which winds up a cable 37 to move the slide 16 as in the previous embodiment described with reference to Fig. 3.

Filed: 1961-06-12
Abstract: 982,987. Parametric devices. SPERRY RAND CORPORATION. June 12, 1961 [Oct. 11, 1960], No. 21142/61. Heading H3B. In a parametric amplifier or parametrically excited resonator, the magnetic vector of a thin film is oscillated by pumping and signalling frequencies the amplitudes of which are together insufficient to reverse the magnetic vector. Magnetic bias enables the operating frequency to be raised. A number of amplifiers may be connected in cascade in a transmission line. Amplifier.-A thin magnetic film 10, Fig. 1, of 10,000 A thickness or less has pumping and signalling windings 18, 16 perpendicular respectively to the easy axis 12 and the transverse axis of the film. The pumping source 28 operates at twice the frequency of the signal generator 20. Bias may be applied by a permanent magnet or by a battery. The battery may be in the pumping circuit or in a separate biasing circuit. Cascade arrangement.-Windings 16 on film elements 10 constitute the series inductance elements of a transmission line, Fig. 6, with shunt capacitors 38. Windings 42 are connected in series to a pump source 40 and delay elements 44 compensate for signal delays in the transmission line. The signal from source 36 is amplified as it is transmitted from section to section along the line. Parametrically excited resonator.-The pumping circuit includes a switch 48, Fig. 7, a biasing battery 58 and a filter 56 decoupling the pump source 28 from subharmonic oscillations in winding 16. A condenser 48 tunes the winding 16 to a subharmonic of the pumping frequency. A signal source 46 and a switch 50 can be used to set the subharmonic oscillation in the desired one of two possible phases separated by 180 degrees. Specification 793,799 is referred to.

Title: A device for producing output signals representing distinct ranges of variation of avariable input quantity
IPC: H03K3/2893
Filed: 1961-06-13
Abstract: 933,361. Electric selective signalling systems. BENDIX CORPORATION. June 13, 1961 [June 28, 1960], No. 21284/61. Class 40 (1). In a system for digitizing an angular displacement and providing a marking on a selected one of a plurality of output leads to represent the extent of angular displacement either a disc 11, Fig. 1, carrying staggered marks 12, is attached to the shaft and as the shaft rotates photo-cells 13 are successively illuminated to successively mark leads 16 or a potentiometer 29, Fig. 4, is attached to the shaft and the voltage so produced is applied a plurality of threshold devices, with different thresholds, and gates to mark a single output lead 35. Both embodiments have the feature that only a single output lead can be marked at any one time, even when the input passes transitionally through the digitizing points. In Fig. 1 this ambiguity preventing is achieved by supplying each photo-cell with a positive potential via the transistor amplifier of the previous stage. Thus the second photo-cell 13b receives its positive potential via a resistor 18a in the first stage so that when the first photo-cell is receiving light, and the first stage transistor is conducting, only too low a positive potential is supplied to the second photo-cell for its transistor amplifier to conduct.

Patent GB-479438-A (GB)
Title: Improvements in the production of acetylene
IPC: C07C11/24
Filed: 1936-08-04
Abstract: Acetylene is made by subjecting normally liquid hydrocarbons to thermal decomposition in two successive steps, the first step being effected at 600--1000 DEG  C., preferably at 800--900 DEG  C., and the second step being effected at above 1000  DEG  C., preferably at 1100--1400 DEG  C.  The process may be effected at any desired pressure, but is preferably effected at below atmospheric pressure and/or with the addition of a diluent, e.g. hydrogen.  The apparatus may comprise a series of tubes, or a single tube heated to the necessary temperatures over different parts of its length. The tubes may contain baffles adapted to cause a turbulent flow of the hydrocarbon vapour, and in this event the temperature in the second step may be reduced to about 950 DEG  C.; various forms of baffle and various methods of mounting the baffles are indicated. The process may be applied to heavy, medium or light oils, such as are obtainable from heavier oils by cracking, with or without hydrogenation; it may be applied also to liquid products obtained from coal by hydrogenation, or by extraction with a solvent followed by hydrogenation of the extract.  In an example, a vaporized light hydrocarbon oil mixed with hydrogen is passed through a set of parallel steel tubes lined with chromium; the first half of each tube is kept at 850 DEG  C. and the second half at 1200 DEG  C.; the products leaving the tubes are rapidly cooled, and the acetylene produced is separated in any suitable way.  The Provisional Specification states that the process may be applied p  to normally gaseous hydrocarbons, and refers to the treatment of propane and butane.
