Title: Improvements in or relating to earth leakage protective devices
Inventor: ANDERSON JAMES
IPC: H02H3/16
Filed: 1962-05-25
Abstract: 1,058,181. Protective arrangements. ANDERSON MAVOR Ltd. Aug. 15, 1963 [May 25. 1962; March 9, 1963; May 15, 1963], Nos. 20119/62; 9462/63 and 19229/63. Heading H2K. An earth-leakage protective and lock-out arrangement comprises a transductor having control windings C1, C2 and balancing windings C3, C4 separately connected to the supply lines, a bias winding C6, A.C. operating windings L1, L2 in series with relay means REL1, REL2 controlling a contactor operating circuit or a circuit-breaker tripping circuit, and a lock-out winding C5 energized on the closing of a switch S1 when the contactor or circuitbreaker is opened. In the arrangement shown, under normal conditions, the effect of the control windings C1, C2 is cancelled by the balancing windings C3, C4, lock-out winding C5 is not energized and the effect of the bias winding C6 is such that sufficient current flows in the winding L1, L2 to energize the relay REL1 which completes the contactor operating circuit. Should an earth fault occur, the leakage current to earth through impedances Z1 .. Z3, rectifier B1 and the control windings C1 C2 unbalances the windings C1, C2 and C3, C4 and the resulting modification of the flux in the transductor core causes a reduction in the current through the windings L1, L2 so that the relay REL1 opens the contactor operating circuit. On the opening of the contactor, switch S1 closes so that D.C. flows from a rectifier B3 through the lock-out winding C5, switch S1, balancing winding C4, rectifier B2, impedances Z4 ... Z6 returning via impedances Z1 . . . Z3, rectifier B1 and control winding C2. If no earth fault exists, the currents in windings C4. C2 balance and the current in winding C5 is balanced by the increased current flowing in the bias winding due to the closing of a switch S2. Should an earth fault exist some current in the lock-out circuit will return through the fault path so unbalancing the effects of the windings C2, C4 and increasing the current in the winding C5. This results in an increase of the current through windings L1, L2 and relay REL2 is sufficiently energized to open its contacts in the contactor operating circuit to prevent the closing of the circuitbreaker. In a modified arrangement, Fig. 2 (not shown), the lock-out winding is directly connected to the supply lines through starconnected impedances and auxiliary switches. Each of these arrangements may be provided with a further relay having operating windings connected in series with the control windings C1, C2 and responding to an increase in voltage on the supply lines due to a faulty supply transformer to open contacts in the contactor operating circuit, Figs. 3 and 4 (not shown). The rectifiers may be, or include, Zener diodes.

Title: Improvements in and relating to brick-making and like machines
IPC: B28B5/08
Filed: 1943-12-03
Abstract: 573,126. Moulding and pressing bricks &c. HEWITT, J. B. Dec. 3, 1943, No. 20228. [Class 87 (ii)] To dispense with a second press in a brickmaking or like machine, whilst producing highquality bricks by a pressing action of comparatively long duration, a single press is used which operates at half the speed at which the clots are moulded and is designed to press simultaneously twice the number of clots that are made in one operation of the moulding machine. For this purpose, the clots are discharged from the moulding machine to the press simultaneously from two moulds or two groups of moulds at the end of two successive movements of the mouldcarrying member. The invention is described with reference to a horizontal rotary table machine. A table 1 has moulds 2, each mould of a pair of moulds being spaced equidistantly from a radial line 4. The table revolves intermittently so that each mould 2 comes in turn under the charging point 3. A pusher 5 operates on two moulded clots ejected simultaneously from two adjacent moulds, once at the end of each two intermittent movements of the table, the clots being pushed into moulds 7 in a press 6 operating at the same speed as the ejecting mechanism. The pressed bricks are ejected from the press by the incoming clots. The pusher may have projecting arms provided with resilient heads which trim the pressed bricks.

Patent GB-422960-A (GB)
Title: Manufacture of improved textile elements and applications thereof
IPC: D06M15/693
Filed: 1933-07-18
Abstract: A textile element, obtained by assembling two or more rovings, each twisted in the same sense to such a degree that it can no longer readily be drawn out, and twisting the assembly in the opposite sense to such a degree that each roving is largely opened up, is subjected to treatment, without tension, with an acid or an alkali, preferably caustic soda, whereby the fibres are swollen and contracted in length, and such treatment may be applied before or after the elements have been woven or otherwise combined together or with elements of another type.  The elements so treated may then be impregnated with a suspension, dispersion or solution of an elastic or plastic substance such as rubber or balata.  Specified textile fibres treated are cotton, jute, flax, hemp and ramie.  In examples (1) a roving of cotton fibre of specified dimensions is given a twist of 200 turns per metre (80 turns ordinary + 120 turns supplemental twist) to the right, a second similar twisted roving is placed parallel thereto and the assembly is given a twist of 200 turns per metre to the left; the whole is then soaked for 5--30 minutes in dilute caustic soda solution at 8--18 DEG  C. and tables are given showing the increases of tensile strength and elasticity of the products obtained with the use of various strengths of caustic soda solution, temperatures and durations of treatment; (2) an assembly of 15 rovings of cotton of specified dimensions each having an ordinary twist of 800 turns and a supplemental twist of 690 turns in the same sense, is given a twist of 350 turns in the opposite sense; (3) an assembly of 2 rovings of cotton of specified dimensions, each having a twist of 140 turns per metre to the right, is given a twist of 140 turns per metre to the left.  Impregnation of the textile elements or of the webs or fabrics prepared therefrom.  The impregnation with rubber or other elastic or plastic material may be effected by application with a brush or in a calendering machine or by soaking, with or without the use of vacuum or pressure.  In the case of rubber it is preferred to apply natural or concentrated latex containing all the ingredients necessary for vulcanization, e.g. by immersion, for about 4 hours at about 20 DEG  C., and the latex is coagulated on the material by a volatile acid such as acetic acid, dried and vulcanized; tables are given showing the tensile strengths and elasticities of the impregnated products.  The impregnated materials are applicable for making ropes, cords, fabrics, webbing, transmission and conveyer belts, hose and brake tubings, tarpaulins, sacks, fishing nets, shoe laces, card clothing, packings, brake blocks, pneumatic tyres, shoe soles, flexible transmission couplings, &c.

Abstract: 1,165,617. Syringes. S.A.C. CONSULTANTS Ltd. April 23, 1968 [May 3, 1967], No.20596/67. Heading F1R. A dispenser, for dispensing paste from a cartridge having a nozzle at its forward end and containing a sliding plunger behind the paste, comprises a body to receive the cartridge and providing a gas-tight working space behind the plunger of the cartridge, an inlet for admitting successive pulses of gas under pressure to the working space, and means for maintaining the volume of the working space substantially constant notwithstanding advance movement of the plunger in the cartridge. Workpieces 52, Fig. 9, to be soldered are carried in succession by a conveyer 51 beneath the dispenser 50, which deposits through a nozzle 10 an accurately metered volume of solder paste on to each workpiece. The solder paste is contained in a removable cylindrical cartridge 2, Figs.2 and 3, of polyethylene which is closed with a tightly fitting plunger 4 of polyethylene. An adaptor 6 screwed into the cartridge carries the nozzle 10. To permit insertion of the cartridge, the body of the dispenser is divided into two parts 12, 15 locked together by a thumb screw 40. A hollow piston 16 is inserted into the body to rest under its own weight against the plunger 4. A timer T controls a solenoid valve 54 to supply pulses of compressed air of predetermined duration through a line 56 leading via a valve 20 into the hollow piston 16. Each pulse acts on the plunger 4 to extrude a corresponding amount of solder paste through the nozzle 10, upward movement of the hollow piston 16 being prevented by a ball ratchet 24, 26. At the end of the pulse, the valve 20 opens a vent E 2  to vent the hollow piston 16 to atmosphere, and the hollow piston then drops under its own weight to the new position of the plunger 4 so that the volume of the working space above the plunger remains substantially constant. Distension of the wall of the cartridge 2 during application of pressure and subsequent dribbling from the nozzle 10 while the wall is recovering from the distension are prevented by equalizing the pressures inside and outside the wall by means of a compensating hole 38. For operation in other than a vertical position, the hollow piston 16 may be spring-loaded.
