Patent GB-442843-A (GB)
Title: Improvements in and relating to the control mechanism of motor vehicles
IPC: F16H63/46
Filed: 1934-05-10
Abstract: 442,843. Controlling change - speed gearing ; Bowden mechanism. LEISSER, V., Langenlois, Kamptal, Lower Austria. May 10, 1934, No. 14181. Void [Abridged as open to inspection under Sect. 91 of the Acts, June 19, 1935]. [Classes 80 (ii) and 80 (iii)] Comprises means for opening the engine clutch 4, Fig. 1, upon a vehicle before the change-speed gear 3 is operated. There is lost motion between the upper part 7 of a ball change lever and the lower part 12, (Fig. 3, not shown), which effects the speed changes, so that the first movement of the part 7 only opens the clutch 4. This first movement through a linkage 16, 19, 20 raises a pivoted cam 21 which has a swell which thrusts a pin 26 to the right and so opens the clutch 4 against its engaging spring. In the arrangement of Fig. 6, the first movement of the lever part 7 moves a slide valve 42 so as to admit compressed air from a source 44 to behind a piston 47. A pivoted segment 37 is thus canted to the left until it engages a pin 38 on the clutch disengaging pedal 6, and so opens the clutch 4. In a form shown in Fig. 5, the clutch is disengaged by the thrusting downwards and outwards of an hydraulic plunger 33, the effort of which is derived from the effort of thrusting the change-speed lever 7 between two cam-ended plungers 30, 31 which in separating displace oil in an hydraulic chamber 32. In an arrangement shown in Fig. 8, it is the effort of grasping the handle of the ball change-speed lever 61 which effects the disengagement of the engine clutch. This grasping closes in two halves 72 of a knob, which motion separates two arms 72<a>, 72b, one acting on a Bowden wire 71 and the other on the sheath 74. A doubled relative displacement of the wire 71 is passed on and through a wedge 70 mounted to slide in a hollow in a guard hood 64 to a continuation wire 71<a>, which disengages the clutch. The wedge 70, which is biassed by a spring 69, passes through a spring plunger 65 which locks the gear lever 61 in gear positions by engaging holes 67 in a socket 63 which supports the ball 62 of the lever. As the wedge 70 is pulled upwards, it pulls the plunger 65 out, so freeing the lever.
Patent GB-371632-A (GB)
Title: Process for treating aluminium phosphates
IPC: C01F7/0673
Filed: 1931-05-13
Abstract: Aluminium phosphate, for instance the basic salt obtained by heating phosphate of lime with an acid solution of aluminium silicate under pressure, is dissolved in dilute caustic alkali by heating using sufficient excess alkali to keep the aluminium in solution as aluminate, and the solution supercooled say to -5 DEG  C. to precipitate trialkali phosphate quantitatively.  The residual aluminate liquor is treated with carbon dioxide to produce alumina and sodium carbonate, whilst the trialkali phosphate is dissolved in warm water and treated with carbon dioxide whereby on cooling say to -2 DEG  C. dialkali phosphate separates quantitatively, and sodium carbonate remains in solution.  Specification 363,909 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following subject-matter:--The production of alkali, for use in the process, by decomposing bauxite with sodium carbonate, extracting the product with water, and precipitating the bulk of the alumina by boiling under pressure; the fractional separation of alkali phosphates from alkaline solutions of beryllium, lead, or tin; carrying out the process by fractional crystallization at ordinary temperature followed by slight supercooling after addition of concentrated sodium aluminate solution; and the production of solutions for treatment by decomposing iron-aluminium phosphates or mixtures of ferrophosphorus and bauxite with sodium or mixed sodium and potassium carbonates or sulphates, followed by extraction with water.  This subject-matter does not appear in the Specification as accepted.

Filed: 1950-06-07
Abstract: 682,276. Automatic gramophones. McKELLEN, S. D. June 6, 1951 [June 7, 1950], No. 14206/50. Class 40 (ii) [Also in Group XXXIX] A gramophone-type alarm device (see Group XXXIX) sets up a telephone connection and transmits a recorded message. In operation in response to e.g. flood, fire, burglary, a relay 18 connects the device to an exchange line and releases the turntable catch 15. After the connection has been set up the pick-up is lowered on to the record under the control of a cam 22 on a shaft 11 driven by the gramophone motor. The turntable 17 rotates until an arm 21 on the shaft 11 operates contacts 86 to release the relay 18 which replaces the catch 15. Alternatively the contacts 86 may be operated when the motor slows down by a lever actuated by the governor. The alarm device is reset after re-winding by pressing a button which completes a circuit for relay 18 to restart the motor. The cam 22 lifts the pick-up support 72 and a projection 80 on the support engages an inclined fixed surface 83 to rotate the pick-up to the starting position in which a latch 84 secures the projection 80 until it and the pick-up are lowered when the alarm device operates.

Abstract: 495,876. Controlling aircraft. BROWN, D. B. W. May 22, 1937, No. 14323. Convention date, July 23, 1936. [Class 4] An aerodyne having a power-driven airscrew includes horizontal tail surfaces, selection means operable to determine whether the surfaces will be operated differentially or in unison and manual means to effect operation of the surfaces or means responsive to the airscrew-driving motor speed adapted, when the selection means is set for differential operation, to operate the surfaces automatically to counterbalance reactionary airscrew torque. As shown, concentric airscrews 26, 27 are driven, respectively, from engines 11, 12 through spurgearing. An additional power take-off for a rotor or road wheels is provided by a disconnectable gear-wheel 34. Spring-loaded centrifugal governors 44 have collars 40 secured to, and collars 41 slidable on, the engine shafts. The collars 41 actuate bell-crank levers 48 which are connected to a member 52 carrying, through a rod 54, the piston 57 of a hydraulic master-cylinder 58. The cylinder 58 is connected as shown through a valve 86 with slave cylinders 60 which contain pistons 62 connected to elevators 80, 81. As shown, movement of one end of the member 52 relatively to the other due to a change in engine speed, moves the piston 57 to operate the elevators 80, 81 differentially to counteract the reactionary torque on the aircraft. If the valve 86 is turned, the elevators are then actuated similarly. The piston 57 may be controlled manually through bell-crank lever 56. The elevators and associated tail planes may be concurrently operated in the same or opposite sense.

Title: A process for exerting an influence on chemical reactions
IPC: B01J19/08
Filed: 1950-06-13
Abstract: Chemical reactions in which inorganic materials are treated at high temperatures are assisted by the emission in the vicinity of the reaction of discontinuous electromagnetic oscillations, of one polarity, having steep fronts and a frequency of 10-100 cycles per second.  The term "steep front" means that the time during which the oscillation rises from its minimum to maximum value is small compared with the duration of the oscillation.  The oscillations are produced by silent electric discharges from an electrode to which is supplied a voltage varying in one direction only.  The varying voltage and the required waveform are produced by means of an electrical circuit, comprising a modulator, thyratrons, transformers, and rectifiers, and fed by alternating current.  A potential difference of 5000-100,000 volts may be used.  The application of the invention to the production of lime by burning limestone is described.  Specification 685,522 is referred to.
