Filed: 1973-10-23
Abstract: 1451095 Change-speed control CHRYSLER UNITED KINGDOM Ltd 22 Oet 1974 [23 Oct 1973] 49312/73 Heading F2D A plurality of axially slidable gear selector rails are interlocked by a disc lying in a plane normal to the axes of the rails and movable in that plane, in response to selection movement of one rail, to a position preventing movement of the other rail or rails, and the rails are releasably held in their various positions by an encircling spring ring. The selection mechanism shown has a reverse selector rail 33, a first/ second ratio selector rail 34 and a third/fourth ratio selector rail 35 arranged in a triangle with their axes parallel, as shown in Fig. 1, and surrounding a disc 37, Fig. 5, which coacts with slots 38, 39 in the rails and is contained within a circular housing 41, 45 secured to a face 36 of the gear-box casing. The slots are so shaped that axial movement of any one rail displaces the disc laterally to lock the other two rails. The rails are located in their neutral and ratio-selected positions by a spring ring 46 coacting with slots 47, 48, 50, 52, 53. An axially movable and rotatable selector shaft 11, Fig. 3, has secured it to a lever 13 and a member 14 coacting with a bell-crank lever 17, 18 and a member 17a secured to a boss 19, Fig. 1, which is slidable on a fixed shaft 21, the arrangement being such that rotary movement of the shaft 11 displaces the assembly 17, 18, 17a, 19 along the shaft 21 to select a particular rail, and axial movement of the shaft 11 turns the bell-crank lever to actuate the selected rail. The assembly is biased by springs 25, 26 to the position shown in Fig. 1 in which the end 54 of the bell-crank lever engages a cut-out 55 in a plate 56 fixed to the rail 35. Displacement of the bell-crank lever against the spring 26 brings it into engagement with a slot 59 of a striker fork 58 fixed to the rail 34, and displacement against the stronger spring 25 causes the bell-crank lever to engage a slot 60 of the reverse rail 33 which has an operative connection with a reverse selector lever 27 rotatably mounted at 28 on the shaft 21. A reversing light switch is operated by a rod 62 coacting with the selector rail 33.

Filed: 1975-12-22
Abstract: 1524730 Lasers SOC EUROPEENNE DE PROPULSION SA 22 Dec 1975 [31 Dec 1974] 52505/75 Heading H1C In a gas dynamic laser in which an energizing gas flow such as N 2  is thermally excited by chemical reaction or an electric discharge and its energy transferred in a resonant cavity to a secondary gas flow such as CO 2 , the energizing gas is preheated prior to excitation by circulating the gas as a coolant for a chamber where the energizing and secondary gases react, or by using a separate heating source. Both preheating methods are used in Fig. 1, in which N 2  from a vessel 4 is circulated by a pump 5 through secondary gas injection structures 21 and the walls of the reaction chamber 2, and is then passed through a heat exchanger 6 and a compressor 13 before entering the chamber 2 itself. Further heat is supplied to the N 2  energizing gas by the heat exchanger, the heat being generated by reacting kerosene and nitrogen peroxide from sources 8 and 10 in a combustion chamber 7. In the reaction chamber 2 the preheated N 2  is introduced through a duct 14 and reacts exothermically with two reactants such as nitrogen peroxide and C 2 N 2 , the reactants passing from respective storage vessels 10, 18 through pumps 11, 19 to injectors 16, Fig. 2. Each injector as shown comprises two rows of orifices directed towards each other to mix the reactant streams. Alternatively the reactant system may be omitted, an electric discharge between two electrodes within the chamber 2 being used instead for exciting the N 2  gas. The secondary CO 2  gas is supplied by a source 24, and is introduced into the resonant cavity 3 by a duct 23 and injectors 26, Fig. 3, where it produces a lasing reaction with the excited N 2  gas. Optical communication through the cavity walls with external resonator mirrors 29, 30 is provided by windows 27, 28, the mirror 29 being apertured to provide a lasing output. After lasing the exhaust gas is passed through a gas diffuser 31 having stepped wall portions 31a to start gas-recompressing shock waves. The exhaust gases may drive a turbine used to operate the pumps 5, 9, 11, 19 and compressor 13, andin the case of electric discharge excitation the turbine may drive a suitable generator. Both chemical heating and electric discharge excitation may be used simultaneously.

Abstract: 1426787 Mechanical game MARVIN GLASS & ASSOCIATES 20 Nov 1973 [20 Dec 1972] 53777/73 Heading A6H A game apparatus comprises a plurality of projectiles 12, a plurality of compartments 48a-48c each capable of receiving a given number of projectiles, overload means for automatically releasing a projectile when that number is exceeded and a launcher 20 for launching a projectile upwardly so that it may fall into a compartment. The discs 12 are inserted through a hole 30. Fortyeight printed discs are provided, equal numbers of which carry cherries, bells, and oranges. A chart is provided to indicate winning combinations. The launcher has a striker slide 76 pulled down against a spring 64 by a lever 70 until tripped. A rubber band returns the lever 70 to its upright position. Each compartment has one pin 108, Fig. 6, projecting through a hole at its lower left-hand side and two pins 102, 104 projecting through holes at the top and centre of the right-hand side. When a disc enters a goal it becomes wedged against the pin 108 and the right side of the compartment. When another disc enters the compartment it knocks the pin 102 and tilts the lever 96 so causing a projection 116 on the lever to tilt a second lever 94 carrying the pin 108, so releasing the previous disc. Released discs fall into a receptacle 124 which can be tilted back by a lever 142 against a spring to pull its lower edge away from the front face of the apparatus and release the discs into a chute 122. At the same time, the overload means are released by a bar attached to a horizontal arm engaging the levers 96, 46 so that all the discs fall into the chute.
Patent GB-538209-A (GB)
Abstract: 538,209. Toothed gearing; actuating electric switches. ROTHERHAM & SONS, Ltd., and LITCHFIELD, S. E. March 2, 1940, No. 3940. [Class 80 (i)] [Also in Group XXXVII] Relates to the toothed gearing of a time-lag device of the kind including a driving element, in a form of a rack or of a quardrant or a wheel with discontinuous teeth, which can engage with a pinion connected to the time-delay mechanism, e.g., a vane, escapement wheel eddycurrent brake or the like, and which will move out of mesh therewith during the operation, the final movement of the driving element being rapidly effected with a view, for example, to operating a switch. According to the inventon, means are provided for effecting rotational movement of the pinion on the return stroke of the driving element and co-relating it to the movement of the driving element so as to ensure proper meshing between the teeth on the return movement. Alternatively, the pinion may be retained in a definite angular position after the driving element has moved out of engagement with it. A continuously toothed wheel 11, Fig 1, and a quadrant 12 are mounted on the same axle and both gear with a pinion 13. The quadrant carries a pawl 14 engaging the teeth of both the wheel and the quadrant. When the quadrant moves from a back-stop 16, the wheel 11 is driven idly by pinion 13 until the quadrant has left the pinion, whereupon the pinion and wheel 11 remain stationary. On the return movement of the quadrant the pawl drives the wheel 11, thus correlating the quadrant and pinion and ensuring'correct meshing between them. The timedelay mechanism is driven from the pinion. Alternatively, the pawl may engage a ratchet wheel fast with the wheel 11; or two co-axial pinions spring-pressed into ratchet-like engagement may gear with the continuous wheel, and with the quadrant just before the latter has left the pinion. In a modification, Fig. 2, the pinion 13a has one tooth missing and the discontinuous wheel 12a has a peripheral portion 22 which engages the teeth on each side of the gap 21 to hold the pinion against rotation. The wheel 12a may be replaced by a rack. In Fig. 4, the rack actuates a pinion 13a fast with a ratchet wheel 41 which drives in one direction a gear 42 in mesh with a pinion fast with a gear 43 which drives the pinion 44 fast with the escapement wheel 45. A stop 32 is adapted to abut a sleeve 33 to ensure that the non-toothed part 31 of the rack does not move away from the teeth at the ends of the gap in the pinion teeth.
