Title: Improvements in and relating to valves
IPC: E02D5/52
Filed: 1920-09-15
Abstract: 173,035. Leevers, F. W. Sept. 15, 1920. Sluice valves; wedging or jamming.-In sluice valves having two oppositely-disposed valve members, which are jammed to their seats in the final closing movement, means are provided for preventing rotation of the valves until concentric with their seats and then moving the valves with a combined rotary and jamming action against their seats. The valve discs 1 are provided with two projections 11 so that they slide between guides 2 without rotation during the opening or closing movement. The discs are kept concentric with one another by means of an axial pin carried by one of them which projects into an axial aperture in the boss of the other. The bosses of the two discs are provided with helical coacting surfaces so that when the discs' are rotated relatively to one another, they are also separated axially. The discs are locked together when they are in a position not concentric with the valve seats by providing a dowel pin 13, Fig. 5, at the bottom of the helix formed on the boss of one disc which engages a hole in a corresponding position on the other disc. In a modification, interlocking notches 6<1>, Fig. 4, are provided. In another modification, the axial pin and its corresponding socket are screw-threaded. Each disc is provided with a projecting pin 7 which engages with a slot 8 in a carrier 9 operated by the spindle 10. When the spindle is operated to close the valve the discs slide between the guides 2 unti they reach their lowest position, whereupon they are free to rotate in the recess in the casing. Further downward movement of the carrier 9 rotates the discs in opposite directions by means of the pins 7, and the discs are simultaneously wedged outwards by the helical or screwed surfaces on the bosses. Specifications 6024/08 and 14863/09 are referred to.

Abstract: 885,693. Counting-apparatus; transfer 885,693. Counting-apparatus; transfer mechanism; zeroizing mechanism. OLYMPIA WERKE A.G. Aug. 18, 1958 [Sept. 12, 1957], No. 26453/58. Class 106 (1).  An electromagnetic counter comprises a plurality of numeral wheels rotatable on a shaft, a transmission mechanism between a drive gear on the shaft and the counter wheels and a zeroizing mechanism including a driven gear, the arrangement being such that when the transmission mechanism is in engagement with the counter wheels and drive gear, the zeroizing mechanism is out of engagement with those members, and vice versa. As shown, Fig. 1, an electromagnet 2 steps a ratchet wheel 6 through a pawl 5, the ratchet wheel 6 being connected to a driving gear 8 freely mounted on a shaft 23 carrying numeral wheels 20. Transfer pinions 13, adapted to co-operate with single teeth 22 on the lower wheels and driving gears 21 on the next higher wheels, are mounted on a shaft 12 carried by arms 10a, 11a of a bracket 9 which has arms 10b, 11b carrying a shaft 15 to which is fixed a driving gear 16, zeroizing pinions 17 being driven from the shaft 15 through slipping clutches 18. During counting the transfer pinions 13 are engaged and to effect zeroizing, a remote switch 32, Fig. 4, is depressed thereby cutting off the counting pulse input at f, and energizing a magnet 3 to rock the bracket 9 thereby engaging the pinions 16, 17 with the gears 8, 21 and disengaging the pinions 13. A relay arrangement A, B then supplies pulses over a contact e to the counter magnet 2 to step the numeral wheels 20 until individual stops 28 thereon contact a rail 25 pivoted on the arm 10a of the bracket 9.

Abstract: 764,075. Liquid-blast switches; switch contacts. ALLIS-CHALMERS MANUFACTURING CO. Sept. 16, 1954 [Nov. 3, 1953], No. 26899/54. Class 38(5) A stationary contact member for use in a liquid - blast switch comprises a plurality of segments 11a...11d grooved to form slots 17, 18 which provide contact surfaces for engaging movable contacts, the slot 17 extending from one end into the member transversely of its longitudinal axis and the slot 18 extending into the member substantially longitudinally of the longitudinal axis. The stationary contact is tubular and may have four segments (as shown) biased by springs 15 which provide loose pivotal mountings for the segments. The slot 17 is of rectangular cross-section and is engaged by the contact tip of a sickle-shaped pivoted contact member (not shown) which is so disposed that the contact tip wipes across the segments and separates from the segments 11a, 11b last. Thus the segments 11c, 11d are current carrying members and the segments 11a, 11b are arcing and current carrying members and may be of refractory material. The slot 18 is cylindrical and is engaged by a rod contact (not shown).

Abstract: 503,497. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Oct. 5, 1937, No. 26971. Convention date, Nov. 14, 1936. [Class 40 (iv)] [Also in Group XL] A receiving circuit for supervisory &c. signals in the form of 60-cycle modulated 1,000-cycle currents and selecting impulses in the form of unmodulated 1000-cycle currents comprises a circuit 1222, 1223 tuned to 1000 cycles and a circuit 1218 .. 1221, comprising series and shunt resonant circuits tuned to 1100 cycles, which peaks at 900 and 1100 cycles. The voltage developed across the coil 1223 is rectified by the right hand one of a pair of diodes 1212 and applied across a resistance 1229 in the grid circuit of an amplifier 1213 against the normal bias derived from the series heater circuit. Voltages developed across the coil 1221, when they are of sufficient amplitude to overcome a normal negative voltage on the anode, are rectified by the left-hand diode and applied to resistance 1230 in the grid circuit of 1213 in the same direction as the normal bias. By this means the response of the signal relays to wrong frequencies is prevented and the input to 1213 is subjected to a limiting action since very strong signals of 1000 cycles produce a big enough drop across 1221 to produce a biasincreasing voltage at 1230. The circuit forms part of a tone unit identical with that described in Specification 500,737.

A method of producing a row of locking members for a sliding clasp fastener comprises punching out a series of equally spaced transverse slots 2 from a flat strip 1 of flexible, elastic synthetic material to form a ladder-like blank, the rung portions 3 of which are enlarged adjacent each side of the longitudinal centre line of the strip, folding the blank about the longitudinal centre line, pressing the halves of the folded blank together so that the superimposed halves of the rung portions are combined to form a row of locking members 8 with enlarged heads and securing the row to a stringer tape. As shown in Figs. 1, 3 and 4 the flat strip 1 of synthetic elastic material is provided with longitudinally extending grooves 18, 19 and 20. A carrying strap 9 and cover strips 10 and 11 are secured by stitching and or glueing to the members 8, the cover strips being extended over the members 8 so that in the closed condition of the fastener, the members 8 are completely covered on both faces. In a modification, Fig. 5, the cover strips are replaced by a pair of bars 30 which are pressed closely on to the locking members and the carrying strap 9 and provide shoulders 31 on which the sliding clasp engages. In other arrangements, Figs. 6 and 7 (not shown), the cover strips 10 and 11 are constituted by a simple strip which encloses the adjacent edge of the carrying strap, Fig. 6 or the carrying strap is integral with one of the cover strips, Fig. 7.

At the required frequency gas bubbles cease to appear on the cathode. In depositing lead, 100- 125 reciprocations per minute may be made, enabling a current density of 100 amperes per square foot to be used. In an apparatus for producing metal strip the cathode b is supported by rollers d mounted on a frame c above the cell a. and is rotated by a chain-driven spring- mounted roller e co-operating with a spring- mounted roller f. The strip is peeled from the cathode, passing between trimming rollers k, k<1>, geared together and driven from the shaft of the roller e, and is wound on to a roller l on which bears a roller l<1> mounted on a frame m pivoted to a shaft m<1> and driven from the shaft by sprocket gear. The cathode is coated with a stripping solution by a pad n and is cleaned immediately afterwards by a pad n<1> before it enters the electrolyte. The deposit on leaving the electrolyte passes under a brush o, roller p, and washing tank q. A curved anode b<1> is employed. Trimmings from the rollers k, k<1> are removed by a shoot k<4>.
