Title: Tripping mechanism
Inventor: DEVLIEG CHARLES BENJAMIN
IPC: H01H3/16
Filed: 1953-02-09
Abstract: 736,527. Linkwork. DE VLIEG CORPORATION. Feb. 9, 1953, No. 3602/53. Class 80 (3). A tripping mechanism particularly for operating the plunger 90 of a switch 87, Fig. 11, comprises a tripping lever 15 secured to a shaft 30 having a driving member 40 with a tooth 41 thereon co-operating with a driven member 57 with a tooth 58 on a shaft 43. The shaft 43 carries an actuating lever 53 with a contacting head 86 for engaging the switch plunger 90. The lever 15 and member 40 are biased by an overcentre spring 76a and the member 57 and lever 53 are acted upon by a spring 76 which acts in opposition to spring 76a to keep the parts in the position shown. A cam member 42 with cam surfaces 91, 92 is also mounted upon shaft 30 and co-operates with a roller 60 on the actuating lever 53. On the tripping lever 15 being engaged by an abutment to move it in a clockwise direction driving member 40 engages driven member 57 to pivot the latter and the actuating member 53 counter-clockwise to release the switch plunger 90. On continued movement of lever 15 the members 40 and 57 disengage but member 57 is prevented from return movement under its spring 76 by the cam surface 92 engaging roller 60 on lever 53. The lever 15 is maintained in its operated position by the spring 76a but on return movement thereof the cam surface 92 passes over roller 60 and finally releases the lever 53 to be restored by spring 76 to its original position. If the tripping lever 15 is moved counter-clockwise from the position shown, the spring 76a acts to retain it in such position without effecting any operation of lever 53. A further lever 48 secured to the shaft 43 is adapted to operate a dial gauge 63 for accurately positioning, for example, a tool or work slide of a boring or milling machine, the switch 87 being used to control approach and feed motor circuits.

Title: Improvements in and relating to means for energizing an electric winding, relay or the like, after a definite time lag
IPC: H01H43/30
Filed: 1924-02-12
Abstract: 233,767. British Thomson-Houston Co., Ltd., and Fitzgerald, A. S. Feb. 12, 1924. Thermal switches in which the time taken to heat up and cool down again is considerable are employed to give a time-delay action so that the energization of a winding takes place some time after a hand-controlled switch is closed. As shown in Fig. 1, in which the hand closure of the switch 11 is arranged to energize the winding 23 after a certain time, the closure of switch 11 energizes the primary 13 of a transformer through the normally-closed contacts 19 of an electromagnetic switch. The secondary of the transformer supplies current to a thermal strip 15 which rapidly heats up, leaves the contact 16 and engages the contact 17, thereby short-circuiting a resistance 22 through which the electromagnet has been feebly energized on the closure of switch 11. The electromagnet switch opens at 19 and prepares the circuit of the winding 23 at 24. It remains in this position, under the weak energization through the resistance 22, while the thermal strip cools down and finally completes the circuit of winding 23 by engaging the contact 16. The winding 23 may be weakly energized through an additional resistance when the contacts 24 are closed and effectively energized when the thermal element cools down, the weak energization being adequate to hold a core when once it has been attracted.

Title: An improved method of and means for charging internal-combustion engines
IPC: F02B33/00
Filed: 1931-02-06
Abstract: 372,369. Mixing and heating charge; regulating. LAUTOUR, F. DE, 155, Cholmley Gardens, London. Feb. 6, 1931, No. 3866. [Classes 7 (ii), 7 (iii), and 7 (vi).] Air or mixture is circulated by a compresser in a closed path 19, 20 over a valve 12 so that the valve is cooled and when it is opened the charge enters the cylinder 10 with a whirling motion. By providing a common wall 37 with the exhaust passage 17 the mixture is heated, and by making the passage 20 smaller in area than the passage 19, or by providing vanes on the cylinder head, the whirling is increased. The passages 19, 20 lead to the delivery and suction sides of a blower 21 which obtains its supply from a carburetter 29, or the atmosphere, through a throttle valve 27. A further valve 31, which may be connected to an aneroid device 34 or a speed-governor, controls the charging pressure, the arrangement being such that the charge either increases, or remains constant, as the speed increases. Quick opening of the valve 12 may be produced by a cylindrical mask rising above its face. Specification 266,144, [Class 7 (ii), Internal-combustion engines, Arrangement &c. of], is referred to.

Patent GB-911174-A (GB)
Title: Improvements in or relating to methods of precipitating waxy substances such as paraffin wax on fibrous substances
IPC: D21H17/60
Filed: 1959-02-04
Abstract: A positively charged, stabilized emulsion of paraffin wax in water is made by melting the wax with a primary alkyl amine, bringing the temperature of the melt to about 20 DEG C. above the melting point of the wax and slowly adding hot water containing an amount of acetic acid equivalent to the amine, accompanied by vigorous stirring.  The acetate of the primary alkyl amine which is formed functions as a cation-active emulsifying agent and can be decomposed, by heat, into a volatile portion and a solid hydrophobic portion.  A change from a water-in-wax to a wax-in-water emulsion occurs.  The emulsion is slowly stirred and cooled to 2 DEG  to 3 DEG C. above the melting point of the wax.  Water at 0 DEG C., e.g. ice water, is then added to lower the temperature of the emulsion, suddenly, to a value below the said melting point and the emulsion is allowed to cool to the ambient temperature. Emulsions of micro-crystalline waxes, vegetable waxes and polyethylene may be prepared by a similar method.  The method may be modified so that a quaternary salt, such as tribenzyl alkyl ammonium chloride or cetyl pyridinium chloride, is utilized as the emulsifying agent.ALSO:A size, from which a waxy substance is precipitated on to paper-making &c. fibres when the size is added to an aqueous suspension thereof, comprises a stabilized emulsion of the waxy substance, e.g. paraffin, microcrystalline or vegetable wax or polyethylene, in water containing a cation-active emulsifying agent, which, for example, completely neutralizes the negative charge on the fibres.  The fibres may be of unbleached cellulosic sulphate pulp, glass, asbestos or a plastic substance.  The emulsifying agent may be a quaternary salt such as tribenzyl alkyl ammonium chloride or cetyl pyridinium chloride or the acetate of a primary alkyl amine which, for example, on being heated, decomposes into a volatile portion and a solid hydrophobic portion.
