Title: Safety device for motor driven vehicles, the gas valve and brake of which are operated by one and the same pedal
Filed: 1933-04-13
Abstract: 404,183. Controlling motor vehicles; brakes. CRISTIANSEN, M. A. A. P., 12, Ole Olsens Alle, Hellerup, Denmark. April 13, 1933, No. 11189. Addition to 396,241. [Class 79 (v).] The depression of a pedal first closes the throttle and then applies a brake, and complete release of the pedal, after the throttle has been fully opened, puts the engine out of action and applies a brake unless a device for restricting the throttle opening has been brought into operation. In the construction shown in Fig. 1, the accelerator pedal 1, when depressed, actuates the brake pedal 8, but the brake pedal can be depressed to apply the brakes independently of the accelerator pedal. The pedal 1 is connected by a link 2 to an arm 3 on a shaft 4 which controls the throttle by mechanism not shown. A disc 5 fixed on the shaft 4 carries contact segments 6, M, S, adapted to be engaged by fixed brushes 7, 9. The shaft 4 is controlled by a spring 12 tending to raise the pedal 1 so as to open the throttle. As the pedal is depressed the throttle is closed and the brake pedal is depressed to apply the brakes. In the normal working positions of the pedal 1 the brush 7 is on the segment 6 and the ignition circuit of the engine is completed. If the pedal 1 is released the brush 7 first leaves the contact 6 so that the ignition circuit is broken, and then makes contact with M and completes a circuit through a buzzer 39 and a solenoid 28 having a lost-motion connection 26 with the brake pedal 8, the brakes being thereby applied. A warning signal 41 is energized by the brush 9 and contact S before the brush 7 leaves the contact 6. The safety device can be put out of action by means of a dashboard control 16 which limits the extent to which the accelerator pedal can rise. The control knob 16 is connected by a Bowden wire 13 to an arm 11 loose on the shaft 4 and having a stop adapted to be engaged by an arm 10 fixed on the shaft. The knob is normally pulled towards the dashboard by a spring 21, Fig. 4, so as to leave the accelerator pedal free to rise to the emergency position in which the ignition circuit is broken and the brakes are applied. When the knob is pulled away from the dashboard the arm 11 is rotated and forms a stop for the arm 10 on the shaft 4. A lug 20 on the stem of the knob works in a slot 17, 18, 19, the part 17, 18 being helical or sloping at such an angle that the knob will remain in any position in which it is left. Thus the accelerator pedal, when released, moves back to any desired position in which the throttle is partly open for starting and slow running. In a modification, the ignition circuit segment 6 is omitted and the throttle is closed, when the accelerator pedal is released beyond the open throttle position, by the cam and pin mechanism described in the parent Specification.

Filed: 1943-07-12
Abstract: 569,260. Gramophone reproducing circuits. RADIO CORPORATION OF AMERICA. July 12, 1943, No. 11267. Convention date, Sept. 23, 1942, [Class 40 (iv)] [Also in Group XL] In a gramophone reproducing or other system in which movements are translated into currents of the kind in which such movements effect frequency or phase-modulation of a current of higher frequency, modulation is effected in a multi -electrode tube with an oscillation-generating section having electron coupling with the output electrode. This tube is followed by a discriminator in the form of a circuit tuned to a frequency slightly different from the mean frequency of the oscillator, and a diode-triode tube for rectifying and amplifying the output of the discriminator circuit. All these elements may be mounted in the tone arm as shown in Fig. 3. In a modification, Fig. 5, only the frequency-modulating circuits are in the tone arm and the frequency-modulated oscillators are taken by a low impedance transmission line to a discriminator 40 associated with a diode-triode tube 22. In this case the leads from the pick-up pass through damping boxes.

Title: An improved method of and apparatus for forming plastic masses such as dough into shaped relatively thin forms
IPC: A21C3/00
Filed: 1944-06-15
Abstract: 594,821. Dough-shaping machines. GRAHAM, D., and GILLILAND, J. June 15, 1944, No. 11420. [Class 87 (ii)] Dough is made into thin shaped forms such as scones by apparatus comprising an intermittently-moving conveyer 4, a bottomless receptacle or pitching frame 29 by which the dough is located on the conveyer, a press 17, roll 31 and cutter 41. When the apparatus is in the position shown in Fig. 1, with the frame 29 resting on the stationary conveyer, dough is placed in the frame. A connecting rod 26 then rises, taking with it the press head 17 and frame 29 (which is secured to 17) leaving the dough on the conveyer. The conveyer carries the dough along to the press and stops, the dough being then flattened by descent of head 17 from the shape shown in Fig. 10 to that shown in Fig. 11. The head rises, and two more steps of the conveyer feed the dough to and through the rolling station, where it is rolled to the shape shown in Fig. 12. A fourth step feeds the dough beneath the cutter 41 which cuts a circular quartered disc from the dough (Fig. 13). This cutter is operated by linkages 45, 46, 47, from press 17: it may be omitted. The frame 29 has two of its corners filled in with blocks, to give the shape shown in Fig. 10. Another form of frame is described, having four holes therethrough. A.s the head 17 rises, it rocks a floursprinkling box 48 to sprinkle flour on to the dough. The operative parts of the head 17 and cutter 41 are adjustably and resiliently mounted on the head and cutter. A rotating perforated drum 49 dusts flour on to the pressed slab of dough to prevent the latter sticking to the roll 31, and a rotating brush 52 removes the dusting flour from the cut pieces.

Abstract: 1374031 Extruding ALLMANNA SVENSKA ELEKTRISKA AB 14 March 1972 [15 March 1971] 11736/72 Heading B3P A hydrostatic extrusion press for tubes has a mandrel 25 which is axially held relative to a die 4 by a spacer tube 8 and the enlarged rear end 26 of the mandrel is sealed in a liquid-tight manner to a plate 27 seated on the spacer tube. The sealing is achieved by seating the rear end 26 of the mandrel in a recess in the plate and by a seal ring 31 clamped by a flat ring 29 to the plate 27. The hydrostatic fluid pressure acts only on the mandrel on one side of its rear end, the other side being subjected to atmospheric pressure in a space 30, so that the resultant pressure opposes the frictional drag on the mandrel by the extruding tube and reduces the risk of fracture. In a second embodiment the mandrel is formed in two parts 43, 47, Fig. 4, sealed by a sleeve 48 and seals 49, 50.

Abstract: 658,705. Thermal switches; magnetic switches. RHEOSTATIC CO., Ltd. May 4, 1949, No. 11944. [Class 38 (v) ] In a differentially-expanding, rod-andtube type thermostat embodying the magnetic snap-switch disclosed in Specification 625,492, the rod 3 freely extends through a magnet support plate 6, a resilient movable contact-carrying member 7, and a fixed-contact carrying plate 8, all insulatingly mounted on posts 4, 4<SP>1</SP> on the base 1. The rod rigidly carries a collar 19 and a loose insulating block 16 having points 17, 17<SP>1</SP> which bear on the centre limb of the member 7 and a ridge B, B<SP>1</SP> on which bears a washer 22 positioned beneath the collar 19. The rod is insulated from the member 7 by a tube 23 slidable on the rod and urged against a recess in the underneath of the block 16 by a spring 24. On rise of temperature the tube 2 expands and the member 7 is moved down by the block 16 whereby a contact 14 on the member 7 disengages an adjustable fixed contact 15 with a snap-action produced by the interaction of the twin-armature unit 12, 13 with the magnet 11, this movement being limited by a stop 21. On subsequent decrease of temperature the pull of the magnet 11 on the armature unit 12, 13 recloses the switch. The thermostat is adjusted by rotating a knob 18 attached to the rod 3, the other end of which screws into the tube 2. Specification 632,904 is referred to.

Abstract: 1,043,806. Valves. BENDIX-WESTING- HOUSE AUTOMOTIVE AIR BRAKE CO. March 20, 1964 [March 26, 1963], No. 11963/64. Heading F2V. [Also in Division G3] A valve suitable for insertion in the line between a compressor and a receiver comprises an inlet chamber 12, a delivery chamber 14 and a check valve 60 allowing flow from the inlet to the delivery chamber. The check valve forms part of a piston 46 slidable in bore 47 and co-operating with a stop 48 carried by a spindle 42. The latter also carries an exhaust valve 36 loaded by a spring 54. When the pressure in the inlet chamber reaches a predetermined value it unseats the exhaust valve with a snap-action and the lowered pressure in the inlet chamber then allows the piston 60 to be driven downwardly by the receiver pressure until it engages stop 48, whereby the exhaust valve is retained open until the receiver pressure drops to a second, lower, predetermined value. In modifications, the piston and exhaust valve are rigidly interconnected, or the spindle 42 is rigid with the piston and the exhaust valve is slidable on the spindle with its loading spring in exhaust chamber 35. A filter may be provided in the inlet chamber upstream of the check valve. The latter comprises an annular gasket supported on a plate 64 retained by a snap-ring 66.

Abstract: 108,738. Ricardo, H. R. Aug. 23, 1916. Buffers; eccentric-actuated pumps; spring-actuated pumps; quick-return motions; stroke, varying; valveless pumps; multiple-delivery piston pumps; delivery pipes; regulating delivery by dash-pots; suction reservoirs.-A fuel pump for an internal-combustion engine comprises a cylinder A opening at one end to a supply reservoir B and communicating at the other end with a resilient delivery pipe C connected to the injection valve. The plunger E works in a guide D on the reservoir and is actuated relatively slowly on the out.stroke by an eccentric rod M provided with a trip finger M<1>, and quickly on the delivery stroke by a spring G compressed between the top of a casing F<1> and a dash-pot piston E<2> carried by the plunger. The piston E<2> works in a chamber F provided with two ports F<2>, F<3> open to the atmosphere. During the delivery stroke, the port F<2> is first covered and the trapped air then escapes by the port F<3>, which is regulable by the engine governor &c. so as to vary the rate of compression of the air and consequently the rate at which the plunger is retarded. When the port F<3> is covered by the piston E<2>, the compressed air quickly stops the plunger and causes it to rebound so that the injection valve closes sharply. The length cf stroke is regulated by the adjustment of the port F<3>. The effective stroke may be varied by mounting the cylinder A adjustably in the reservoir B. The pipe C may be made of metal with an oval cross-section, and its resilience ensures a substantially constant delivery pressure. Several pumps may be arranged in parallel in a tubular reservoir B, the eccentrics being all mounted on the shaft L.
