Patent GB-131960-A (GB)
IPC: F41F3/10
Abstract: 131,960. Schneider et Cie. Jan. 17, 1918, [Convention date]. Launching torpedoes.-Consists in interlocking the mechanism for opening the front door of a torpedo tube with the mechanisms for releasing and ejecting the torpedo, so that the launching is performed automatically by the single operation of opening the door. In the form shown, the front door B is hinged at B<1> and is worked through a sector B<2> and a rack d by a piston C in a cylinder E supplied with compressed air under con'trol of a valve H. A tail rod F fixed to the piston C has a shoulder F<2> for tripping a bell-crank L, L<1> for removing a retaining catch L' from engagement with the torpedo Q in the tube A as the door reaches its open position. The tail rod has also a collar F' for tripping a launching lever j<1>, j<2> which actuates a valve i controlling the main valve I admitting compressed air from a tank I<1> to the tube A behind the torpedo Q as soon as the door is fully open. When the door is in the closed position, the tail rod is locked by a pawl M on the rod in conjunction with a spring-controlled lever N, N<1>; and this lever is in its turn locked by a bell-crank O, O<1> until the handle G of the valve H is swung to the left for supplying compressed air to the cylinder E behind the piston C and connecting the front end of the cylinder to exhaust for opening the door. Provision is made to work the apparatus by hand by means of (1) a spindle r geared by a sector R to a rack F<3> on the tail rod and (2) a handle S for the launching lever j<1>, j<2>; the collar F<1> is then preferably removed, and a ring s<1> is attached to the launching lever and embraces the tail rod F to prevent the opening swing of the launching lever until the front door is open when a notch F<4> in the tail rod comes opposite the ring s<1>.

Abstract: 420,958. Vacuum gauges. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET, Võsteras, Sweden. May 3, 1934, No. 13387. Convention date, May 4, 1933. [Class 106 (ii)] Comprises a resistance 1 located in the vacuum to be measured and formed from a strip of metal foil fed from a source 5 of alternating current and connected to an electrical measuring instrument 7, 8 through one or more transformers 4. A condenser 6 may be connected in parallel with either winding of the transformer, and, as shown, the instrument is of the iron ring type with a voltage coil 8 connected through a resistance 9. The instrument indicates the proportion between voltage and current and may be graduated in terms of vacuum. The current through the resistance 1 and the voltage across the latter may be transformed by separate transformers which may have one condenser each for compensating exciting currents, and further, the iron resistance for keeping the current constant may be arranged on different sides of the current transformer employed. A bridge method or other differential method may be used, or if the current is kept constant, a voltmeter. The resistance 1 of platinum or aluminium foil is made in two parts in order to make connections 11 at the same end. At the opposite end the two parts are connected by a guided metal body 12 which is held in good heat contact with the vessel 2 by springs 13.

IPC: H01H71/44
Abstract: 135,311. Fuke, F. C., and New Switch- Gear Construction Co. Nov. 22, 1918. Dash-pots.-In timelag devices of the dashpot type described for use with electric switches &c., the bottom of the fluid container or the piston or both are formed cupshaped with a slot or aperture in the wall of one part and a number of different sized slots in the other part so that by adjusting either the piston or the container rotatably or axially, the time of operation of the retarding device may be varied. As shown in Figs. 2 and 3, the fluid-container is adjustably secured as an extension of the guide tube of a solenoid core a to which a hollow plunger is secured depending into the container and slotted for engagement by a key on the cover of the container to ensure non-rotational movement. The lower closing-cap of the container is formed with an annular ridge constituting a cup, and the ridge is formed with a single slot p. The piston on the lower end of the plunger is in the form of an inverted cup, the wall of which is provided with a number of different sized slots. A disk resting on the top of the piston closes holes i in the piston in its upward movement, but permits free downward movement. By relatively rotating the piston and container, holes of different size in the piston may be made to coincide with the hole in the cup of the container, and consequently the time of operation of the dash-pot may be varied. This time may be varied also, by axially raising the piston. The piston may fit within the cup instead of around it, and both piston and cup may have double concentric walls. The cup may be constituted by a restricted portion of the container, the wall being slotted.

Abstract: 918,024. Endless conveyers; hydraulic jacks. BEUKENBERG, H., and BEUKENBERG, H., [trading as MASCHINENFABRIK GLUCKAUF G. KLERNER]. April 27, 1959 [April 25, 1958], No. 14372/59. Classes 78 (1) and 78 (3). [Also in Group XXIX] Two pairs of hydraulic props are used in advancing a conveyer towards a working face. As shown, an I-section guide beam 5 extends through a slide 9 connected to one end of the beam by a piston-and-cylinder motor 12. An hydraulic prop 8 is pivotally mounted on each end of the beam. Also associated with the beam is a base 16 provided with two hydraulic props 17, the beam and base being connected by a further piston-and-cylinder motor 18. A rigid arm 22 fixed to the beam and displaceably supported on the base 16 or on the side of the motor 18 causes the base to advance towards the working face when the slide 9 is advanced along the beam 5. The upper end of the conveyer is supported on a plate 15 extending from the slide. Assuming initially that the props 8 have been extended to secure the beam 5 and the props 17 are retracted, the motor 12 is now actuated and the slide 9, together with the base 16, is advanced towards the working face. The props 17 are then operated and the base pressed against the floor. Advantageously, before the extension of the props 17, the motor 18 is actuated so that the base 16 is moved to its maximum distance from the slide 9. When the props 17 are extended, the conveyer can be moved by the motor 18 towards the upper end of the wall 1, the props 8 having been retracted. During actuation of the motor 18 or immediately subsequent thereto, the motor 12 is again actuated and the beam 5 is advanced and then secured by extension of the props 8. Hydraulic prop construction.-In Fig. 7, an inner part 24 is guided in an outer part 23 and is moved upwardly by hydraulic medium supplied through a pipe 25, against the action of a spring 26. A head 27 is connected by a ball-and-socket joint to the inner part 24, and the outer part 23 is pivoted at 28 to the prop base. Springs 29 between the base and the outer part are adjusted so that the prop normally extends obliquely. In a modification, Fig. 8, the outer part 23 is connected through a ball-and-socket-like connection 30 to a baseplate 31. A ring 32 which may be of rubber, causes the prop to extend obliquely. An hydraulic system for actuating and controlling the props is described (see Group XXIX).
