Abstract: 1,041,671. Trueing grinding wheels. W. FERD. KLINGELNBERG SOHNE G.m.b.H. Feb. 12, 1965 [April 2, 1964], No. 6113/65. Heading B3D. A tracing device for the grinding wheel of a tool-sharpening machine comprises a cylinder 4 adapted to be secured to the guard hood 1 of the grinding wheel, a piston having a rod 5 protruding from both ends of the cylinder, a template 14 arranged parallel to the axis of the cylinder, and a trueing diamond 12 and a feeler pin 10 carried on arms 11, 9 secured to the rod, rotation of the rod during its longitudinal movement causing the same deflection of the trueing diamond as the deflection of the feeler caused by the template. The feeler pin 10 is urged into engagement with the template by a spring urged pin acting between a post 15 and the arm 9 and the pin is carried for adjustment in the arm by a fine-pitched screw. During reciprocation of the piston in its cylinder, the rod is caused to rotate by the pin and template to cause a corresponding movement of the diamond. The template may be formed by the grinding wheel which may be conical and is initially accurately trued by a known rollertrueing device. The template may be concave to produce a domed profile on the grinding wheel which is used for sharpening the teeth of a cutter.

Abstract: 1,063,361. Converting ground polythene particles to spherical form. PERMUTIT CO. Ltd. Feb. 2, 1965 [Feb. 13, 1964], No. 6118/64. Heading BSA. Ground particles of polythene are converted to spherical form by passing them through a heating zone at such a rate that fusion occurs, while preventing coalescing of the particles during the heating and cooling. As shown, polythene chips 2 pass into a grinder (1) from which ground particles are carried in a current of air along a pipe (5) into an air separator (6), the air being drawn off through a pipe (7) while the ground particles fall under gravity down a tube (9) through a heated zone (11) and into a fluidized bed of particles overflowing from a container (12) into another container (13) from which cooled particles are delivered through a pipe (16). The bed is fluidized by air introduced through a pipe 14 and some of the fluidizing goes up the tube (9) to delay downward passage of the particles. The heating zone may be by infra red, gas flame, radiant heaters or otherwise. The polythene chips may be ground to a size which will yield spheres of average dimension 1,000 microns or less after fusion. An embodiment is described in which the ground particles pass upwards through the heating zone.

Title: Improvements in copying telegraph systems
IPC: H04N1/00
Filed: 1936-03-02
Abstract: 468,864. Copying telegraphy. FARNSWORTH TELEVISION, Inc. March 2, 1936, No. 6266. Convention date, March 27, 1935. [Classes 40 (iii) and 40 (v)] Each line of a picture 1 is scanned a plurality of times to produce successive identical trains of impulses, and from each of the successive trains, impulses are selected for transmission which are within a different amplitude range. An electron image of the picture is scanned five times horizontally by a deflecting coil 14, which is energized from a saw-tooth oscillator 19 controlled by a twenty-cycle generator 28, before the image is moved vertically to the next line by a coil 20, energized through variable resistances 37, 38, 39, which are stepped in value by an amplified impulse from a four-cycle generator 27. Amplified signals are applied negatively to a gas-discharge tube 49, which is given a positive bias by 56, and positively to a tube 51, which is given a negative bias by 57. The plates of the tubes are energized by a two-thousand cycle generator 58. One or other of the tubes will conduct except for an amplitude range in the signals which overcomes the bias on 49, but not that on 51. When this occurs, the current through a resistance 70 is sufficient to overcome the bias of an over-biassed high-frequency amplifier (not shown) in a transmitter 71 and a signal, which is of constant amplitude and duration, is transmitted. A different range of signals is selected on each successive scanning of each line by varying the bias on the tubes 49, 51 by amplified current through resistances 88, 89 from a photo-electric cell 83, which is illuminated through a variable transparency 80 on the same shaft 25 as the generators 26, 27, 28. A synchronizing signal is transmitted by connecting leads 30, carrying the twentycycle pulse, through an amplifier to the keying resistance 70. Receiver, Fig. 4. The signals are applied to a cathode-ray tube 103 with a fluorescent screen having a large time lag to give a visual image, and to a cathode-ray tube 105 with an instantaneous screen, the light from which is focused on light-sensitive material 106. The light intensity is varied in stages by the bias given to electrodes 130<1>, 131<1> by the effective part of a resistance 130. At the end of the first scanning of a line, an amplified impulse from a scanning oscillator 116, which is controlled by the synchronizing signals, is applied to a winding 147 to short a portion of the resistance and lock the relay over an arm 148. This arm also operates a winding 150 after a delay due to the charging of a parallel capacity 151, which permits the impulse from the amplifier 146 to die away first. The relay shifts the output of the amplifier to a winding 152 in a second bias relay, and so on at each synchronizing signal.

Abstract: 488,227. Aerating liquids. PETERZEN, C. F. L. March 4, 1937, No. 6416. Convention date, March 5, 1936. [Class 14 (i)] Relates to a system of carbonating liquids wherein the liquid is first de-aerated and then is maintained under an atmosphere of carbondioxide while it is cooled, passed to a heatinsulated container, and finally taken to a carbonating apparatus. The de - aerating apparatus comprises a chamber 1 with windows 2, an outlet 8 for de-aerated liquid, an inlet 16 for liquid and a pipe 15 with connections to a vacuum pump and a source of carbon-dioxide under low pressure. The pipe 8 includes a valve which opens when the chamber I is filled with liquid and closes when it is empty. The pipe 16 is controlled by a valve 51 and delivers to spray pipes 53 54. The pipe'15 includes two chambers 18, 19, the chamber 18 being connected to the source of carbondioxide. Movable in the pipe 15 is a piston 29 which is linked to a lever 45 and is urged by a spring 64 to the position shown, in which passages 38 in it connect the chamber 18 to the chamber 1. At this time, carbon-dioxide enters the chamber, and de-aerated liquid is discharged by the pipe 8. When the chamber 1 is emptied, a float 12 engages a lever 49 to rock the lever 45 to raise the piston 29 and open the valve 51. The chamber 1 is now connected to the vacuum pump through the chamber 19 and ports 40, 27, 28, 30, and the supply of carbon-dioxide is cut off. The lever 45 is locked in this position by a lever 59. Liquid discharged into the chamber 1 as a fine spray by the pipes 53, 54 is do-aerated as a result of the evacuation of the chamber 1, and collects in the chamber. The float 12 rises until it engages a member 63 to trip the lever 45 and lower the piston 29, and the cycle is then repeated. A splash guard 57 is provided above the pipes 53, 54.
