Title: Improvements relating to vulcanizing presses for recapping pneumatic tyres
IPC: G05F1/563
Filed: 1957-05-08
Abstract: 860,001. Retreading tyres. FROHLICH, A. H., and HARRIS, E. J. May 8, 1957 [May 9, 1956; July 9, 1956], No. 14653/57. Class 87(2). A bagless vulcanizing press for recapping pneumatic tyres comprises a pair of relatively movable mould sections 11, 14 having opposed bead seats and defining when closed an annular tyre cavity, a sealing ring 16 received between the opposed bead seats and providing within a tyre received in the cavity a substantially closed chamber 100, means for delivering a vulcanizing medium into the chamber, and means for removing condensate from the chamber during vulcanization, the mould sections being so movable on opening of the press that the cured tyre is automatically stripped therefrom. As shown, the upper mould section 14 is pivtoally carried by arms 48, 49 which are journalled on the ends of a connecting rod 55. This rod 55 is slidable in slots 56 in side plates 12, 13 of the press by means of toggle links 58, 35. Thus to open the press a rod 37 connecting the toggle links is moved to the left in Fig. 3, by means of a threaded shaft 62 movable axially by means of an electric motor 63 pivotally mounted on the press at 64. The arms 48, 49 are guided by means of an idler roller 70 on one side and a spring-loaded roller 71 on the other. During upward movement of the mould section 14 a lug 80 carried by arm 48 engages a concave free end of a spring loaded lug 74 pivoted at 75 to the side plate 12. This engagement produces a single transverse oscillation of mould section 14 with respect to mould section 11 to facilitate removal of the tyre. The sections 11 and 14 are connected by a telescopic link member 38 which causes tilting of the upper section when the press is fully open. A safety bar 81 if contacted by a person during closing of the press will pivot to operate a solenoid which produces reversal of the motor 63. The annular bead ring 16 has serrated edges 83, 84, Fig. 4, adapted to engage the internal bead surfaces of a tyre and a diametral member 85 having internal conduits 86, 87 communicating with plugs 27, 28 respectively. These plugs fit into flared open ends of adaptors 25a, 26 supported by a bracket 23. Fluid under pressure can thus be supplied to the interior of the tyre T through adaptor 26, plug 28 and conduit 87, and condensate removed through a flexible conduit 88, conduit 86, plug 27 and adaptor 25a. Figs. 7 to 9 (not shown) illustrate modified supply and exhaust valve arrangements, while in Fig. 10 (not shown) the press incorporates a superheater.

Title: Improvements relating to propulsion apparatus for trolley buses and like electric locomotives

Filed: 1934-05-18
Abstract: 438,442. Propulsion apparatus for electric vehicles. STONE & CO., Ltd., J., Deptford, and PRESTIGE, J: T., 1a, Cockspur Street, both in London. May 18, 1934, Nos. 15015/34 and 1512/35. [Class 104 (iii)] In an electric vehicle having an auxiliary installation comprising a motor-generator set 1, 2 and a battery 4, emergency means 9, 10 are provided for coupling the motor-generator set to the traction wheels and for supplying the set with current from the battery. The generator 2 or both the motor 1 and generator may be used as the emergency drive, and in the latter case the motor 1 may be cut out after the vehicle has started. The control mechanism 10 of the coupling means 9 closes a switch 11 and so energizes a relay 12 to open the circuit of a relay 13 and open the isolating switch 8 of the main supply 19. The closing of the switch 11 also energizes a switch relay 14 to close a circuit from the emergency starting switch 15 to the armature of the generator 2. When the switch 15 is on contact a, it connects the field 16 of the generator to the battery, and the armature to the battery through a resistance 17. As soon as the vehicle begins to move, the switch 15 is moved to contact b, thus connecting the armature directly across the battery. A proportion 3<1> of the lamps may be cut out by a relay 18 controlled by the switch 11. In a modification a circuit is provided between the battery and motor 1 to enable both motor and generator 2 to drive the vehicle so long as the starting handle is on contact a.

Title: New automatic system for dynamically anchoring a floating installation

IPC: G05D1/02
Filed: 1968-03-28
Abstract: 1,219,942. Automatic position control. INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS. March 28, 1968 [March 29, 1967], No.15018/68. Heading G3R. Electrical position-correcting signals controlling at least two propulsion units of a waterborne installation, and produced when the deviation exceeds a predetermined value, increase with respect to time until the deviation or its rate of change are suitably modified and cancelled when the deviation or its rate of change are further suitably modified. As described, the position of a ship or drilling rig relative to horizontal perpendicular axes is determined by tiltmeters associated with a line tethering the vessel to the sea bed. Signals from these meters are compared at D, Fig.3, with signals from potentiometers X o , y o  representing the desired position of the vessel. Deviation signals so derived, such as #X relative to one axis, are then applied, e.g. to a comparator 1, so that if they exceed, in either sense, predetermined values set on potentiometers AX o , an output renders a generator 2 operative to apply pulses to a counter T 1  or T 2  according to the sense of deviation. The counter thus produces an increasing signal which is applied through an amplifier A 1  or A 2  to a computer "Calc" which automatically corrects the position of the vessel by appropriately varying the magnitude and direction of thrust of two propulsion units on the vessel. Signals similarly derived from deviations relative to the other axis, Y, and/or from heading deviations, O, are also applied to the computer to assist correction. The propulsion units may be propellers adjustable about vertical axes or fixed in direction with adjustable pitch. When the deviation has been reduced below the value #X o  no further pulses are produced by generator 2 and the correction signal is maintained constant until the vessel reaches its desired position whereupon the operative counter T 1  or T 2  is reset to zero through line 9 so that correction ceases. The deviation signal applied to comparator 1 may be made intermittent by a continuous interrupter 14. In a modification, a signal derived by differentiating the deviation signal is utilized to render generator 2 inoperative when the deviation ceases to increase or when a predetermined time interval has elapsed thereafter. The magnitude of the correction signal may be stepped to a higher value when the deviation ceases to increase. The counters may be reset before the vessel reaches the desired position or when the rate of decrease of the deviation exceeds a predetermined value. The frequency of generator 2 or the gain of amplifiers A 1  A 2  may be automatically varied in dependence on the rate of change of the deviation.

Title: New quaternary ammonium salts and process for making them
Filed: 1953-05-29
Abstract: The invention comprises quaternary ammonium compounds of the formula <FORM:0741112/IV(a)/1> where R1-R4 are C1-C3 alkyl, R5 and R6 are methyl, ethyl or aralkyl and A is an anion. These are made by known methods from 4 : 41-diamino-dibenzyl or its N-substitution derivatives, e.g. by treatment with alkyl halides, dialkyl sulphates or esters of alkyl- or arylsulphonic acids.  The resulting quaternary salts may be converted into the corresponding hydroxides by treatment with anion exchangers, silver oxide (A=halide) or barium hydroxide (AA=sulphate), and from the hydroxides organic and inorganic salts may be prepared. The chlorides and bromides can also be obtained by treating the iodides with the corresponding silver halides.  In the examples the following salts are prepared: (1) R1-R4=methyl: R5 and R6=methyl (chloride, iodide, methosulphate), ethyl (iodide), propyl (iodie, p-toluenesulphonate), benzyl (bromide, iodide), m - methylbenzyl (bromide), p - methylbenzyl (bromide), p-nitrobenzyl (bromide), p-chlorobenzyl (chloride) and p - methoxybenzyl (bromide); (2) R1-R4=ethyl: R5 and R6= methyl (iodide), ethyl (iodide and chloride) and chloride) and benzyl (bromide).  4 : 41 - Bis - diethylamino - dibenzyl and 4 : 41 - bis - propylamino - dibenzyl are obtained by reacting 4 : 41-diamino-dibenzyl with ethyl iodide and propyl bromide respectively.
