Abstract: 992, 694. Reading records photo-electrically; recording-apparatus; course recording apparatus. RAYTHEON CO. June 6, 1961, No. 20442/61. Headings G1A, G1F and G1J. [Also in Division H4] A ship's radar cathode-ray tube (C.R.T.) P.P.I. display 1 is recorded electrically by a stylus 23 on a chart 41 moving at a speed proportional to that of the ship by causing an optical system 28... 31 to rotate rapidly about an axis 35 in synchronism with stylus arm 22, axis 35 being caused to progress around the periphery of the C.R.T. and a photo-electric device feeding electrical signals to the stylus. Assuming that the ship is moving on a constant heading, on the chart a stationary object appears as a single mark e.g. 53, "own ship" track appears as a line of marks 55 and a ship moving on the same course and at the same speed appears as a line of marks 54. Stationary objects appear darker than moving objects, and the faster a moving object the lighter the track marks on the chart. The signals to the stylus may be periodically interrupted; the length of the segment of the track of a moving object is then a measure of its speed. To obviate tearing of the chart by the rapidly rotating stylus, shaft 21 may be slightly tilted from axis 35.

Title: Process for the production of shaped articles from highly polymeric materials
IPC: B29C48/395
Filed: 1966-05-10
Abstract: 1,103,123. Extruding polyethylene terephthalate &c. E.I. DU PONT DE NEMOURS & CO. 10 May, 1966 [10 May, 1965], No. 20714/66. Headings B5A and B5B. In a process for extruding highly polymeric material susceptible to hydrolytic and oxidative degradation such as linear polyesters, polycarbonates and in particular polyethylene terephthalate, the polymer in undried particulate form is fed from feeder 19 to extruder 12, which may be a heated twin-screw extruder, to join similar material in melt form which is moving through the extruder in an oxygenfree environment. As shown, blended melt thereafter passes through a filter 13 to a nozzle 14 and the extrudate, which may be a film, is received on a quenching device 15. An oxygen-free environment within extruder 12 is achieved either by applying vacuum to vent 22 or by circulation of a dry inert gas such as nitrogen. According to the invention, degradation, measurable as a decrease in intrinsic viscosity, is further prevented by the flow of melt through the extruder which is derived either from source 10, which may be a continuous polymerization unit or batch autoclave, or from initial melting of particulate material. In either case part of the melt is recycled via conduit 16. With such recycling, polymer from source 10 may only be used initially with subsequent 100% use of particulate material. The particulate material is preferably reclaimed waste and is not necessarily identical to the melt. A further feeder 21 is provided so that additives such as fillers, pigments, metallic particles, delusterants, anti-static agents and flame-retardants may be introduced. Seven examples are given and in one of these the particulate material differs from the melt, viz. a copolyester of ethylene terephthalate/neopentyl terephthalate is added to polyethylene terephthalate. Additives specifically mentioned are silicon dioxide, aluminium powder and a green pigment. Several examples relate to the production of film which may or may not be subsequently stretched.

Filed: 1927-08-09
Abstract: 301,943. Hall, F. H. Aug. 9, 1927. Hand and foot actuation; force-transmitting mechanism.-In hand or foot levers for operating vehicle brakes comprising upper and lower parts hinged together and a brake rod connected to the upper part so that in applying the brakes both parts move together until the brake is actually applied and the upper part then hinges on the lower part so as to apply the pressure at an increased leverage, the brake rod is arranged at such an angle to the lower lever as to ensure the lower part being inherently locked against return movement without the use of external abutments or constraining means. The lever 1 carrying the pedal 3 is hinged at 4 to the lever 2 mounted on a fixed pivot 5. The brake rod 8 is connected to the lever 1. A spring 7 may be connected to the two levers the inward movement of which is limited by abutments 6. The rod 8 is arranged at an angle not greater than 8‹ to the lever 2 when the brake is applied. When pressure is applied to the pedal the levers at first swing together about the pivot 5 and when by reason of the resistance offered by the rod 8 when the brake is applied, the movement of the lever 2 ceases, the lever 1 turns about the pivot 4. By arranging the lever 1 at an angle of 60-90‹ to the lever 2 the spring 7 may be dispensed with without preventing the initial collective movement of the two levers. A stop 10 for the lever 2 may be provided.

Title: Improvements in pulse counter or step wave voltage generating circuits
IPC: H03K25/00
Filed: 1946-07-12
Abstract: 624,705. Frequency dividing circuits; step wave generators. RADIO CORPORATION OF AMERICA. July 12, 1946, No. 20949. Convention date, Aug. 22, 1945. [Class 40 (vi)] A stepped sawtooth waveform is generated from a train of pulses by causing the pulses to unblock a valve having an integrating capacitor in its cathode circuit. The circuit may be used for frequency dividing, in which case the capacitor is discharged when the voltage across it reaches a predetermined value, or for controlling a multi-channel pulse communication system when the capacitor is discharged by a device responsive to a synchronizing pulse. Frequency dividing, first arrangement- (Fig. 1). Incoming pulses cause normally non- conducting valve A to conduct and charge capacitor 12 in step fashion until the voltage across it is sufficient to cause valve D, provided with a large cathode bias and having its grid connected to the capacitor, to conduct and thus apply a positive-going voltage change through a transformer E2 to the grid of a valve C which conducts heavily as its anode current flows through the same winding as that of valve D causing regeneration. The capacitor 12 is discharged through a valve B whose grid is connected to that of valve C so that it conducts when valve D conducts. The frequency divided pulses are taken from a winding 13 on E2. The division factor is adjusted by varying the cathode bias resistor R of the valve A and thus the charge applied to capacitor 12 per incoming pulse. Frequency dividing, second arrangement- (Fig. 4). Incoming pulses are applied to valve A and cause it to conduct charging capacitor 12 in step fashion until normally non-conducting regenerative coupled valve K conducts, discharging the capacitor and producing an output pulse across tertriary winding 13 on the feedback transformer. The division factor is controlled by varying cathode bias resistors R and R6. Application to multi-channel time-modulated pulse systems-(Fig. 3). Incoming pulses applied through a valve J to a normally non- conducting valve A cause it to conduct and charge a capacitor 12 in step fashion until a synchronizing pulse selected from the incoming pulse on a width basis and applied through a cathode follower stage G causes a valve B to conduct and discharge the capacitor 12. The stepped sawtooth waveform appearing across capacitor 12 is applied to pulse selector circuits through cathode follower stage 18. A valve Bl is arranged to conduct when valve B conducts so as to discharge stray capacitances appearing across the output circuit.

Class 65(1) [Also in Group XXXII] A mine car 10, Figs. 1 and 3 (Provisional 21020/54) has drop - bottom doors 12a, 12b, to which track wheels 11a, 11b are attached by springs 13 and hangers 14. Channels 15 are provided at the sides of the car for engaging rollers 16 carried on support means spanning a discharge pit, so that the weight of the car can be transferred from the wheels 11a, 11b to the rollers 16. The doors 12a, 12b are provided with triangular plates 18 with slots 19 allowing limited vertical movement of cross shafts 20 carried by links 22 which are pivoted at 21 to the plates 18. The links at their upper ends have projections for engagement with catch plates 24 to lock the doors when the cross shafts 20 are at the bottom of the slots 19. Each cross shaft 20 has rollers 23 which engage an abutment 28a on a guide 28 when the mine car approaches the discharge pit. This causes the cross shaft to be raised and the door to be unlatched. As the car moves further forward the weight of the door is transferred from the wheels to the rollers 23, which travel down an inclined part of the guide rail 28, allowing the door to open gradually. In the arrangement shown in Fig. 1 (Provisional 36615/54), the discharge pit D is spanned by members B provided with flanged wheels A which engage channel members 15 forming part of the mine car. Each member 15 has a latch plate 24 adapted to engage a latch 22 on a cross shaft 20 which passes through a slot 19 in a plate 18 carried by the drop-bottom door 12a. As the mine car approaches the discharge pit a tripper F engages a shoe F<SP>1</SP> on the shaft 20 to raise the shaft and cause unlatching of the latch 22 from the plate 24. Also a wheel 11a on the door 12a and a roller R on the shaft 20 run down one track rail 29 and the door opens gradually. The track rail 29 is disconnected from track rail 30 which is eventually engaged by the wheel 11a and roller R and the latch 22 reengages the latch plate 24. In a modification the end of the drop-bottom door is engaged by a latch on a cross shaft provided at the ends with cams which are operated by fixed plates carried by the members spanning the discharge pit.
