Title: Improvements relating to hydraulic brake devices for vehicles of a train
IPC: B60T11/10
Filed: 1939-08-12
Abstract: 533,518. Hydraulic brakes. GALLUSSER, H. Aug. 12, 1939, No. 23299. [Class 103 (i)] In a hydraulic system for a train of vehicles, each vehicle is provided with an electrically controlled valve which supplies pressure liquid from a tank on the vehicle to the brake cylinders, the pressure in the cylinders depending on the current strength, mechanical means being provided for operating the valves automatically in the event of a breakage of a coupling. The equipment on a motor vehicle includes a pump 11 driven by an electric motor 19 supplied by a dynamo 7 and battery 21 and which pumps liquid from a tank 12 to a pressure reservoir 10, the pump being automatically disengaged at a predetermined pressure. A control valve device 14 connected to the tank 12, reservoir 10, and brake cylinders 16 at 30, 33, 39 respectively comprises a piston 22 connected to an electromagnet 40 and engaging a second piston 23 which cooperates with a valve 34. The end of the valve device is closed by a bellows 26 attached to the piston 22 and the casing 14 and oil can escape from the bellows to the tank 12 as the piston moves downwards, by passages 31 and recess 27. The magnet 40 is connected across conductors e, f connected respectively to the battery and to a contact 9 on the pedal 17 which co-operates with a resistance 8. The conductors e, f and also conductors c, d for the pump motor 19 extend to the trailer vehicles the equipment on which is the same as on the motor vehicle with the omission of the pedal switch and current source. Normally the cylinders 16 are connected to the exhaust tank 12 by passages 33, 28, 29, 30. Depression of the pedal 17 by energizing the magnet 40 engages the piston 23 with valve 34 thus closing the exhaust passage 28 and then depressing valve 34 to supply pressure liquid from the reservoir 10 to the cylinders 16 by passage 39, chambers 37, 32, passage 33. When the pressure in the cylinders and chamber 32 acting on the piston 23 is sufficient to overcome the force of the magnet the piston returns sufficiently to permit closure of the valve 34 on its seat 36 to cut off the supply. To effect automatic application of the brakes when a coupling breaks, a cable 44 extending between a pair of vehicles is connected at its ends respectively by pins 50, 51, plungers 48, 54, linkage 43 to levers 42 connected to the valves 14 of the two vehicles. The plunger casings 45, 52 are respectively secured to the vehicles. The pin 51 is connected to the plunger 54 by a multi-part nut 57 held to engage a toothed part of the pin by annular springs 56. A pull on the cable due to breakage of the coupling thus operates the valves 14 and the pin 51 then pulls out of the nut. Spring bolts 49, 58 engage behind the pistons to lock them and the valves in the operated position.

Title: A quick action device for actuating barrel type switches provided on electrically driven tools
IPC: F22G1/00
Filed: 1933-08-22
Abstract: 406,287. Snap - action switches. SIEMENS - SCHUCKERTWERKE AKT.- GES., Siemensstadt, Berlin. Aug. 22, 1933, No. 23388. Convention date, Aug. 22, 1932. [Class 38 (v).] A snap-action mechanism for a barrel type switch particularly for electrically driven tools comprises a handle 18 loosely mounted on a switch spindle 14 which has keyed to it a sleeve 20. A coiled spring 22 surrounds the spindle 14 and is held in place by a washer 23 so as to be enclosed by the sleeve 20 and have its ends projecting through a gap in the sleeve. The ends of the spring also p oject into a recess 24 in the handle. The lower end 13 of the switch member has keyed to it a spindle 15 formed with four depressions which reacts with a pair of spring- pressed balls 17 to hold the switch spindle in each of its four operative positions and to restrain it while the actuating spring is being strained. In operation when the handle 18 is turned, one face of the recess 24 engages the corresponding end of the spring 22 which is thus strained and tends to rotate the spindle by means of the reaction of the other end of the spring with the gap in the sleeve 20. When the restraining force of the balls 16 is overcome the spindle moves rapidly to the next position.

Title: An improved fastening device for use with bolts and like threaded members
IPC: F16B5/06
Filed: 1939-08-15
Abstract: 522,938. Bolting ; nuts. TINNERMAN, G. A. Aug. 15, 1939, No. 23504. [Class 89 (i)] A sheet metal fastener made by stamping from strip metal has thread engaging formations 12, 13, weakening notches 15 in the part that will form the shank portion, prongs 18 that spring out to engage the underside of the part 16 to be secured and prevent withdrawal of the fastener and ends 17 that form flanges acting as a head. On insertion the fastener takes the form Fig. 2, the notches 15 causing the shank to collapse as Fig. 3 when the screw is tightened. In a modification the thread engaging aperture is circular with a lateral slot that enables the edge of the aperture to be offset to helical form. Fig. 5 shows a modification with longer prongs 30 that are doubly bent to extend round the opening in the part 16. In a further modification the notches and prongs are omitted and the shank part of the strip is bent up substantially to circular form. Fig. 11 shows a further form of blank the projections 40 forming the head portion. In a modification disengagement by mere rotation in the opposite direction is rendered difficult by forming the thread-engaging portion of the fastener to a helical form different from that of the bolt, causing the fastener to cut into the bolt thread.

Title: Fluid pressure motor, particularly for automobile propulsion
Inventor: PEDRICK ARTHUR PAUL
IPC: F01B1/06
Filed: 1970-05-15
Abstract: 1,255,915. Radial cylinder engines. A. P. PEDRICK. May 15, 1970, No. 23590/70. Headings F1B, F1M and F1S. A radial cylinder engine comprises one or more pairs of generally triangular rotors having arcuate sides 5, each pair being mounted one at each end of a bar 9 connected with an output shaft 10, the rotors being arranged to roll upon the inner ends of pistons 6 radially movable in bores of a drum, the pistons after having been moved radially outwardly by a rotor being then urged inwardly by fluid-pressure, the rotors being thereby continually rotated producing an output torque in shaft 10. The fluid-pressure applied to the piston may be derived from compressionignition of a fuel/air mixture, Fig. 6 (not shown), or by compressed air or other gas, Fig. 8 (not shown), or by spark ignition of a mixture of air and gaseous fuel, Fig. 7. In Fig. 7 inward movement of piston 6 blocks off exhaust ports 11 and then by action of the rotor surface 5 against the ends of spindles 21 opens valves 20 to allow an air/fuel mixture from a carburation device to enter the combustion space below the piston through ports 22. Further movement of rotor 5 causes sleeves 23 of spindles 21 to block off entry of the mixture and spark plug 24 then ignites the mixture in the combustion chamber. After ignition the exhaust gases pass through ports 11.

Title: Three-film superconducting signal translating device
IPC: G11C11/44
Filed: 1963-06-14
Abstract: 1,003,780. Super - conductive devices. SPERRY RAND CORPORATION. June 14, 1963 [June 27, 1963], No. 23706/63. Heading H1K. A gate circuit comprises three metallic films 1, 3, 2, separated by insulating layers 4, 5, the middle film 3 at least being super-conductive to provide an energy gap which normally prevents passage of electrons (by tunnelling through the insulating layers), but permits such a passage when a suitable signal is applied to the middle layer. As shown Fig. 2, the device is normally biased so that the Fermi level a of the film 1 is opposite the forbidden band b, c of the middle film. When a positive pulse is applied to the middle film however the energy levels of the middle film are depressed and electrons immediately below the level a in film 1 may then tunnel to film 3 and thence to film 2 to produce a negative output pulse at terminal 11. Fig. 4 illustrates an arrangement analogous to a pentode, pairs of films 1, 2 and 2, 2<SP>1</SP> having interweaving films 3, 3<SP>1</SP> with energy gaps b, c, b<SP>1</SP>, c<SP>1</SP>. Positive pulses must be applied to both 3 and 3<SP>1</SP> to produce an output at 11<SP>1</SP>. An output terminal 11 may also be provided, an output thereat being provided when only film 3 is pulsed. Fig. 5 illustrates a further embodiment in which a plurality of strips 3 are located between films 1 and 2. Pulsing of any of the strips 3 produces an output at terminal 11. The materials of films 1 and 2 may also be super-conducting if desired. Suitable materials may be gold for film 1, lead for film 3 and aluminium for film 2. Alternatively three lead films may be used. The insulating material may be aluminium oxide, silicon monoxide or a resin known under the Registered Trade Mark " Formvar ".

Title: Process and apparatus for utilising and measuring variations of illumination
IPC: G01J1/54
Filed: 1936-08-31
Abstract: 469,636. Photometric apparatus. CHILOWSKY, C. Aug. 31, 1936, No. 23775. Convention date, Aug. 31, 1935. Addition to 463,994. [Class 97 (i)] [Also in Group XXXVII] Comprises modifications of the apparatus according to the parent Specification, for measuring or utilizing variations in illumination by electrolyzing HC1 and subjecting the mixture of hydrogen and chlorine to the light which causes them to recombine at a rate depending on the intensity of illumination. According to Figs. 1 and 1a, the apparatus comprises three distinct parts, namely a reaction chamber 107 containing the HC1 and electrodes 2, 2<1>, a diaphragm chamber 150, and a U-tube 110 containing mercury. The chamber 150 contains a flexible glass &c. membrane 100 between plates 105, 106 which provide a free space on each side of the membrane, these spaces communicating by tubes 108, 109 with the chamber 107 and tube 110 respectively. Thin glass blades 101, 102 are cemented to the plates 105, 106, and the membrane 100 and blades 101, 102 are secured together. The movement of the mercury in the tube 110 may be caused by means of a contact 37 to control the illumination of a lamp 10. The tube may also carry contacts 70, 71 connected to resistances 72, 73 in circuit with the electrodes 2, 2<1> so that when the mercury covers the contact 70 the electrolytic current is increased and when it lies between contacts 70, 71 the current diminishes. When the mercury is depressed below the contact 71 the circuit is broken. Fig. 10 shows a form in which light' is concentrated by a lens 91 on a small area of the glass reaction chamber 92, the rest of which is silver-plated on the outside. Fig. 12 shows a form consisting of chambers 122, 124 connected by a tube 125 and mounted on a pivot 121. Movement of the liquid along the tube causes turning movement about the pivot and consequent actuation of a mercury switch &c. 120. In another form, the rapid variation of volume or of pressure resulting from the heating or cooling of the gases under the action of a sudden variation in light intensity, is utilized to provide an indication or to close a circuit.

Patent GB-993352-A (GB)
Title: Article handling machine, particularly for loading articles on a pallet
IPC: B65G57/00
Filed: 1961-07-05
Abstract: 993,352. Packaging-machines. FMC CORPORATION. July 5, 1961 [July 8, 1960], No. 24219/61. Heading B8C. The control mechanism of the machine described in Specification 993,353 is re-designed in order to stack articles on pallets. Articles are fed into the machine on a conveyer DC carrying pushers 164, the leading article operating a switch to stop the conveyer DC and start an accumulator conveyer AC. Further switches, corresponding to the number of rows in each layer of articles when stacked, are provided between rollers 140 of the conveyer AC in order to alternate the movement of conveyers DC and AC. The last row of articles on the conveyer AC operates a circuit to lower a stop 280, thereby releasing the assembled articles on to a reciprocable transfer carriage TC. When the first row of articles abuts a stop plate 205 the under-surface of the articles forms a stationary pressure surface above rollers 40 of the carriage TC which are frictionally rotated anti-clockwise through V-belts. The pressure of the articles causes the rollers 40 to move rearwards against the resistance of springs 95. The articles are dropped on to a pallet P which has been raised on a table T. When the conveyer TC is retracted, it operates a switch to lower the table T sufficiently to receive a further layer of articles. Lowering of the table T to its fullest extent energizes a conveyer C to remove a loaded pallet to the rear of the machine, i.e. to the right in Fig. 2. An empty pallet, fed in from the front of the machine, operates a switch when at a position above the table T to raise the table. When in raised position, an arm on the table T causes the motor raising the table to be de-energized and starts the motor operating the feed conveyer DC.
