Title: Mining apparatus
Inventor: BOLTON DOUGLAS HERBERT HEWLETT
IPC: E21D23/26
Filed: 1963-10-16
Abstract: 1,025,879. Advancing mining conveyers. DOWTY MINING EQUIPMENT Ltd. Oct. 7, 1964 [Oct. 16, 1963], No. 40892/63. Heading F1P. In a mining apparatus wherein a conveyer is advanced towards the receding working face by a series of fluid pressure operated jacks each jack has an associated valve assembly 9 (Fig. 2, not shown) including a pressure reducing valve 49 and is operable to cause pressurization of a line connected to the next valve assembly 9 to thereby trigger operation of the associated advancing jack, and fluid reduced in pressure by a predetermined amount by passage through the reducing valve 49 of the next valve assembly flows through the reducing valves 49 of successive valve assemblies to cause operation of their associated jacks until the pressure reaching a valve assembly is insufficient to cause operation of its associated jack. Each valve assembly 9 has a handle 16 movable in an anti-clockwise direction if valve assemblies to the right are to be pressurized, or clockwise if valve assemblies to the left are to be pressurized. Assuming the handle 16 of the extreme left valve assembly 9 is moved in an anti-clockwise direction to move a valve member 19, fluid from a pressure line 13 passes through chambers 23, 28, a line 31, and a non-return valve 34 into a line 15 connected to the next valve assembly 9. Pressurization of the line 15 opens a valve closure member 40 in the next valve assembly 9 to pressurize its associated line 12 and cause operation of the conveyor advancing jack controlled thereby. Pressure fluid in the line 12 then flows through the pressure reducing valve 49 where its pressure is reduced by a predetermined amount before pressurizing a further line 15 connected to the next valve assembly 9 which thereafter operates in an identical manner to the valve assembly described. Hence each successive valve assembly is supplied in turn with a reduced pressure supply, so that ultimately the pressure supplied to the line 12 associated with a particular valve assembly 9 is insufficient to operate valves A, B (Fig. 3, not shown) controlling operation of the advancing jack. Each assembly 9 also includes a non-return valve 34, a pressure reducing valve 48, a valve closeure member 44 and a valve member 18 arranged to allow the series of jacks to be operated in the opposite direction.

Title: Telephone dial tester
IPC: H04M1/24
Filed: 1975-10-16
Abstract: 1483007 Testing impulse transmitters STANDARD TELEPHONES & CABLES Ltd 16 Oct 1975 42446/75 Heading H4K To test a telephone dial the operations of wind-up and subsequent release to the rest position of its finger-wheel 1 are carried out and monitored automatically and repeatedly. The dial is mounted on a plate 3 and an artificial finger 18 is located in one of the finger holes. A motor-driven, continuously rotatable (about shaft 7) arrangement 6 carries a spring-loaded driving member 12 which may be set by a solenoid-operated device 23, 24 to a position of engagement with the finger 18. The (clockwise) rotation of arrangement 6 causes the dial to be wound-up until the resistance of the fingerwheel 1 to rotary motion overcomes the spring loading-15-of member 12. This normally occurs when the finger-stop is encountered. At this point the wheel normally returns to its rest position, and this return is detected by a position sensor 21. This sensor actuates a control circuit which then energizes the solenoid 23 to return member 12 to its engagement position. Sensor 21 may be a photo-cell arrangement operated when a vane 19 attached to the finger 18 enters a slit 22. The resulting control circuit output causes rotation of the solenoid arm 24 into a position where it can contact end 14a of a toggle 14 to which member 12 is attached. This member thereby resumes its engagement position. The wind-up/release sequence is repeated until either a pre-set count is indicated (by suitable circuitry) or the dial wheel becomes jammed. A second position sensor 25 may be provided adjacent the finger-stop so that the following may be tested for: (a) incomplete wind-up; (b) slow dial return; (c) fast dial return.

Abstract: 936,616. Membrane supports in electrodialysis cells. NEDERLANDSE ORGANISATIE VOOR TOEGEPAST - NATUURWETEN - SCHAPPELIJK ONDERSOEK TEN BEHOEVE VAN NIJVERHEID, HANBEL EN VERKEER. Dec. 16, 1960 [Dec. 17, 19 No. 42992/59. Class 41. An electrodialysis membrane separator and support is of corrugated or net-like organic polymeric material, has ion exchanging properties at least at its outer surface and is of a configuration to provide at least one free path for liquid between perm-selective membranes which it supports. The ion exchanging properties may be imparted to a preformed separator by chemically treating it or by adhering ion exchange particles to it. Alternatively, separators having the ion exchange properties may be formed directly from a mixture of an ion exchange powder and a binding agent, such as polyethylene powder, or from a monomeric substance containing ionic groups. Anion or cation or mixed exchanging properties may be provided. Many examples are specified, e.g. preformed separators of polyvinyl chloride or a copolymer of vinyl chloride and vinylidene chloride are treated with nitrogen containing compounds such as ethylene diamine, pyridine or pentamethyl guanidine; polyvinyl chloride is treated with sulphur-containing substances; polymer or copolymers of styrene may be treated with chlorosulphonic acid or sulphuric acid or with chloromethyl methyl ether, followed by aminating. Further, the supporting device may be treated with chlorine-containing reactants, with hydrogen peroxide, perchloric acid or phosphoric acid. The structure of the separator may be a perforated corrugated sheet or sheets as disclosed in Specification 736,888 or a sheet of expanded material as disclosed in Specifications 863,396 and 836,555. For example, in Fig. 2, two corrugated sheets 5, 6 of thermoplastic material charged with ion-exchange material, are perforated and have projections 2 which with an intervening sheet of fabric 7 prevent the supports from nesting together. In further modifications the assembled diaphragms and supports are illustrated with the corrugations of adjacent supports at right angles to each other. Specification 877,239 also is referred to.

Abstract: 434,564. Electromagnetic switches. LANDIS & GYR AKT.-GES., 1, Hofstrasse, Zug, Switzerland. Aug. 31, 1934, No. 25101. Convention date, Sept. 15, 1933. [Class 38 (v)] In a step-by-step switch, on successive energizations of an operating motor, the operating shaft of a contact device is moved through a definite angle in the same direction against the action of a spring which returns the rotor of the motor to a starting position after de-energization of the motor coil. As shown in Fig. 1 the motor drive comprises an induction disc 5 with driving magnet 4 which rotates toothed gearing 6 the large wheel of which is held against a flat plate 9 secured to a shaft 7 by a spring 8. The rotation of the gearing on energization of an operating motor rotates the shaft 7 against a spring 12 through an angle between fixed limiting stops 14 during which rotation a pawl 19 carried by a cranked member 11 secured to the shaft 7 engages a tooth of a three-toothed ratchet wheel 16 mounted on a contact-operating shaft 15 stepping round an operating cam 17 which in one of its operating positions engages a roller 27, Fig. 4, carried by a spring-supported contact arm 26 and brings contacts 25, 23 out of engagement. The cam member 17 is formed with two operating surfaces 29, 30 so that it may be removed from the contact shaft and reversed so varying the angular position at which operation of the contacts takes place. The contact shaft may be fitted with an external operating handle 18 so that the contact shaft may be rotated manually if the switch has failed to operate and thus fallen out of step with other switches which are energized simultaneously. On cessation of the operating current the shaft 7 and the driving disc are returned by the spring 12 to their initial positions the tooth 19 slipping over a tooth of the ratchet wheel on the contact shaft in readiness for a succeeding operation.
