Title: A telescopic shock absorber
IPC: F16F9/06
Filed: 1956-10-12
Abstract: 808,934. Hydraulic shock absorbers. NSU WERKE A.G. Oct. 12, 1956 [Oct. 15, 1955], No. 31171/56. Class 108(3) A hydraulic shock absorber comprises a high pressure chamber 14 from which fluid is displaced through a piston 1 to a low pressure chamber 15, and a spring- loaded low-pressure storage chamber 6 for the reception of any leakage and of the surplus volume of the fluid, which is returned to the chamber 15 on piston movement in the opposite direction, the chamber 14 being disposed between the chambers 6 and 15. The chamber 15 is connected by a passage 5 in the piston rod 10, a transverse port 8, an annular space 17, and a transverse port 11, with the chamber 6.

Title: Improvements in valve devices for controlling gas flow
Inventor: THOMAS OTTO
IPC: F23N5/10
Filed: 1959-09-14
Abstract: 914,493. Valves. VAILLANT, H., [trading as JOH VAILLANT KOMM.-GES.]. Sept. 14, 1959, No. 31216/59. Class 135. A valve device for controlling gas flow to a gas heater comprises an electromagnet 28 energizable in response to heat provided by a pilot flame of the heater, an armature 18 arranged to be retained by the electromagnet when energized, a main gas valve having a closure member 15 for co-operation with a seat 5, and urged by a spring 16 to the closed position, a coupling 22, 25 connecting the valve member to the armature, and manuallyactuable means 7, 8 for opening the valve so that the valve member is retained in its open position by the electromagnet when energized, the coupling being manually releasable and the manually actuable means being arranged to act directly upon the armature to move the latter into contact with the electromagnet against the action of a further spring 20. As applied to a water heater, the valve member 15 is formed, on the downstream side, with an extension 14 in which a plunger 7 is slidably mounted, a slot 14<SP>1</SP> being provided for a guide key 11 secured to the plunger. An extension 23 is provided on the upstream side of the valve member for the reception of the hook 22 formed on the end of a non-rotatable armature pin 17; the hook is coupled to the extension 23 through a spring clip 25, Fig. 4a, located in a slot 24 in the extension. In operation, when the handle 8 is depressed, the end of the plunger 7 abuts a pin 27 which, in turn, abuts the hook end 22 thereby via the coupling, lifts off the valve member from its seat 5 and also presses the armature 18 against the poles of the electromagnet 28; gas now flows through an inlet 2 and an outlet 6 to a pilot jet, the main outlet 3 being closed by a valve 12. The electromagnet is then energized through a thermoelectric device associated with the pilot jet and, upon release of the handle, the valve 12 is opened and the valve member 15 retained in its open position by the electromagnet. To close the valve member 15 while the pilot jet is still slight, the handle is rotated through 90 degrees, thereby disengaging the coupling and allowing the valve to close under the action of the spring 16.

Abstract: 1,006,715. Spark gaps. LICENTIA-PATENT VERWALTUNGS G.m.b.H. Aug. 15, 1962, No. 31322/62. Heading H1X. [Also in Division H2] An excess voltage protection device or diverter comprises a stack of magnetic blow-out arc gap devices, in each of which straight portions of electrodes 3, 4 converge to form an ignition gap 6 and thereafter diverge at a wider angle before extending part way along parallel or substantially parallel side walls of an arc-quenching chamber. The latter is formed by a ceramic base 1 and a cover secured thereto, e.g. by rivets inserted in bores 5. Arc splitter plates 18 and exhaust openings 16 are provided. The top and bottom walls of the chamber may converge towards the openings 16 to increase the cooling effect, and may be of undulating form to increase the effective width of the chamber. The electrodes may be of square or round section and may be made of copper or brass. The base 1 of a modified device (Fig. 6, not shown), is circular in shape and the cover is formed by the base of the device immediately above in the stack. The orientation of the electrodes in successive chambers is staggered as determined by the position of a notch of each device which engages a recess in the adjacent device. Electrodes of adjacent devices are either soldered together externally of the stack or spring- pressed together inside the stack.

Abstract: 1278071 Continuous casting VEREINIGTE OSTERREICHISCHE EISENUND STAHLWERKE AG 20 June 1969 [23 Aug 1968] 31394/69 Heading B3F To obtain a more uniform cooling of continuously cast steel, a stream 15 of steel is directed to the region of the axis of the mould 1 to form the axial region of the casting while a coaxial outer stream 14 which is hotter, e.g. by 60-70 C., is directed to the outer region. The streams may be from the same ladle, the inner stream 15 being coooled on its way to the mould. As shown, a bar of round or square section is cast, the hotter stream 14 encircling a tube 11 which conducts the stream 15 from a cooler ladle 5 of steel through a tundish 3. The tube 11  may extend down only to the tundish outlet 10 so that the streams are in contact before they reach the mould.

Title: Improvements in or relating to holders for tubular electric lamps
IPC: H01R33/08
Filed: 1948-12-04
Abstract: 663,467. Lamp holders. SMART & BROWN (ENGINEERS), Ltd., and STEVENS, B. Dec. 5, 1949 [Dec. 4, 1948], No. 31454/48. Class 38 (i). In a holder for one end of a double-ended tubular lamp, socket contacts for receiving lamp pins, and an element comprising part of the holder are movable longitudinally against independently mounted springs so that subsequent to insertion of the lamp pins into the sockets, longitudinal movement of the lamp can be continued to enable the pins at the other end of the lamp to be aligned with and inserted in a similar holder by reverse longitudinal movement of the lamp. The sockets 1 are mounted, e.g. by soldering, in the ends of conical springs 5 and are loosely coupled by an insulating strip 2. The bases of the springs lie in recesses 12 in the holder base 4 and have leads connected to their bent-out ends. Alternatively the bases of the springs may lie in metal cups having radial lugs to which the leads are connected. A hood-like cover 6 constituting said element and having flared contact entry apertures 7 encloses and limits upward movement of the sockets and is capable of sliding movement along pillars 13 which hold together the base 4 and a circular casing 9. Springs 11 on said pillars urge the cover to its outermost position shown in which flanges 8 thereon engage flanges 10 on the casing 9. The pillars are hollow and tapped to receive mounting screws. Both the sockets and the cover are also capable of rocking and slight lateral movement to accommodate inaccuracy in the lamp construction. When both ends of the lamp have been inserted in the holders, an equilibrium position of each holder will be obtained wherein the sockets are pressed out of engagement with the cover 6 which will also be pressed in to some extent by the end of the lamp.

Abstract: 658,304. Rotary engines. ROSE. A. A. Dec. 10, 1948, No. 32073. [Class 110(ii)] A rotary internal-combustion engine has axially sliding vanes 25 and means to vary the timing of the ignition obtained from sparking plugs 47 initially, and hot-gas flashback when the engine is running steadily. Each vane is formed of a number of plates with springs which may press pairs apart radially, axially and circumferentially to secure efficient sealing. The volume of each expansion chamber is greater than each induction chamber. The rotor 22, carried on the shaft 21, is provided with sealing rings 39, Fig. 3, which have a series of staggered slots in their edges, Fig. 7 (not shown). Further sealing rings 40 prevent the escape of gas across the rotor periphery and are attached to the inner surface of the stator 20. The plug 47 is carried by a housing 48, rotatable in a side wall of the stator and the housing outlet port 55 is eccentric to the housing axis and exceeds in diameter the width of a vane unit. Rotation of the housing varies the timing of ignition of the gases in the working chambers. The housing is forced on to its seat 50 by gas pressure, and held in place by a locknut 51. Cooling and lubricating liquid is led into the engine through a duct 42 and eight radial ducts 43 leading to an annular groove 44 in the rotor periphery and a stator groove 45 having a discharge port 46.
