Title: Improvements in sockets for electric lamps and the like
IPC: H01R33/22
Filed: 1935-03-19
Abstract: 448,576. Two-part couplings. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and EASTAUGH, H. W. C., c/o General Electric Co., Ltd., Wembley, Middlesex. March 19, 1935, No. 8558. [Class 38 (i)] A socket to receive the cap of an electric lamp, discharge device, or the like, comprises a member adapted directly tc engage the cap and to grip it and another member adaptec to be fixed to a support, botl of the members comprising spherically shaped surfaces adapted to engage each other and to move relatively to each other, so that they form a cup-and-ball joint. In the example, a metal socket 1 is screw-threaded at its upper end to receive the cap of a discharge lamp, its lower portion 4 being convex and conforming to a portion of the surface of a sphere. The member 1 is surrounded by a porcelain cylinder 2 which has a part-spherical concave portion 6 and an internally screwthreaded lower end 8 to attach it to a porcelain support 9. The latter member is recessed to receive a terminal block 11 attached to a tag on the metal shell 4 and a terminal block 12 attached by a strip 13 to a centre contact 16. A spring 14 is located within a recess 15 and bears upon the rear of the contact 16. When a lamp cap is screwed into the socket 1 the reaction between the parts is such that the spherical portions 4, 6 are forced into engagement with each other, but the socket can rotate over a range limited by its screwthreaded end 3 bearing against the member 2. The arrangement may be modified by providing the concave portion on the socket and the convex portion on the member which is attached to the support.

Title: Improvements in and relating to inks and other pigmenting and like compositions
IPC: C09D11/02
Filed: 1921-03-19
Abstract: 183,513. Waele, A. de. March 19, 1921. Ink. - Inks and other pigmenting and like compositions for printing, duplicating, &c. comprise as the vehicle for the colouring-matter an emulsion or emulsoid in the form of a plastic solid, of which the yield value, (defined as the finite pressure it is necessary to apply before any flow through a capillary orifice takes place), is materially greater for the emulsion than for its components, the yield value of the components being, for example, zero. The composition may have the property of breaking down when brought into contact with paper or other porous material, one of the components being absorbed thereby. One of the components may be an oleaginous material, such as Yorkshire grease, wool fat, wool wax, or adeps lanae, a wax such as Japan wax or bees-wax, or a soap insoluble in water, and the other component may be water, the components being emulsified with or without the use of emulsifying agents. The water forms the internal phase, and preferably acts as the sole solvent for the colouring-material, which must be of such a nature as not to break down the emulsion or reverse the relationship of the phases. Pigments such as graphite, which are selectively wetted by the external phase, may also be used. The oleaginous material may be mixed with a thinning-agent. A thickening- agent such as gum or starch may be dissolved in the water, but the addition of a substance to delay evaporation is unnecessary. A salt of a polyvalent metal may also be added. Three examples are given, as follows :-(1) Yorkshire grease is dissolved in a light mineral oil and the solution incorporated with a ten per cent solution of nigrosine in water; (2) aluminium stearate is treated with a light mineral oil and emulsified with a five per cent solution of nigrosine in water; (3) a mixture of Turkey red oil, glycerine, and castor oil, with a pigment such as graphite, lamp black, or hydrated alumina, is emulsified with water.

Title: Electrical protective relays
Inventor: HOEL HANS
IPC: H02H7/26
Filed: 1964-03-02
Abstract: 1,090,862. Protective systems. ENGLISH ELECTRIC CO. Ltd. Feb. 26, 1965 [March 2, 1964], No. 8628/64. Heading H2K. A protective system comprises a distance relay at each end of a protected section, each relay including a non-directional element 17 initiating the transmission of a control signal to the other relay upon a fault occurring within a distance which embraces all of a number of zones of protection extending from both relays, the zones of each relay being provided by a directional element 10 and together extending over the whole of the protected section. On the receipt of a control signal, electromagnetic switches 21, 14 and 22, 23 extend the initial zone of the relay and prevent the tripping of the circuit breaker at that end. The directional element 10 has contacts 16 for interrupting the transmission of the control signal and contacts 15 for tripping the circuit-breaker when a control signal is not received. If a fault occurs in the protected section within the initial zones, i.e. zone 1, of both relays, both elements 10, 17 in each relay respond, the elements 10 closing contacts 15 to trip the circuit-breakers before the transmission of the control signals can prevent such tripping. If the fault occurs in the protected section in zone 1 of one relay (A) and in zone 2 of the other relay (B), the elements 17 cause the transmission of the control signals, but element 10 in relay (A) responds sufficiently quickly to trip the associated circuit-breaker before the incoming signal can prevent it. The transmission of control signals from relay (A) ceases so that contacts 23 at relay (B) reclose but as the electromagnetic switch 21, 14 has a delayed drop-off, the contacts 14 remain open for a short period extending zone 1 of this relay so that the element 10 operates to trip the associated circuit-breaker. For a fault outside the protected section neither circuit-breaker will trip. The element 17 also controls the operation of a further electromagnetic switch 26, 13 which operates with a time delay to change the operation of the element 10 from zone 1 to zone 2 so that tripping is obtained for a zone 2 fault should the transmission arrangements fail. Semi-conductor switching devices may be used instead of the electromagnetic switches.

Filed: 1947-03-31
Abstract: 646,705. Process and apparatus for treating bristles. MORER, A. March 31, 1947, No. 8710. [Class 19] A process of treating bristles, including horse-hair and natural 'fibres, for brushes and brooms, by boiling or steaming in bundles and subsequently dry in g and cooling, is characterized by compressing the bristles against flexing and preventing endwise movement by applying clamping means circumferentially around each bundle for substantially its full length and end covers on each bundle and maintining the clamping means and end covers in situ throughou the treatment. Suitably, the bundle of bristles is housed in a receptacle having a semi-cylindrical bottom, end spaced apart sufficiently to receive the bundle and prevent substantial end movement of the bristles, a curved lid to fit over the bundle, means for clamping the lid down on the bundle so that the bundle is firmly held circumferentially and openings in the receptacle permitting entry and flow therethrough of the boiling water or steam and drying air. The bundles may be used in the form as received from the suppliers. As shown, the lid 18 fits over the bundle of bristles and between the walls 13, 14 ; a length of flexible material such as a cord is bound round the lid and receptacle utilizing the provided slots 20. The bundle itself may be tied by a cord 11. Other Figures (not shown) show similar receptacles provided with two and three pairs of slots and designed to accommodate longer bristles. The Provisional Specification states that the bundles of bristles received from suppliers may be broken up into small bundles and similarly treated in a receptacle wherein the walls and bottom are flat.

Abstract: 550,723. Making films of thermoplastic substances. MONSANTO CHEMICAL CO. July 16, 1941, No. 9008. Convention date, July 31, 1940. [Class 2 (ii)] Thermoplastic substances such as cellulose esters or ethers or vinyl resins are made into webs, sheets or ribbons by extruding the substance in the form of a self-sustaining web and directly thereafter imparting polish or other surface finish to the web, first to one face thereof and then to the other face, without the use of calender or ironing rolls or the like ; the web may then be seasoned if required. Thus, the substance is extruded as a web between an adjustable die blade 25 and a highly polished roll 20, and passes around the roll, whereby its under surface is polished. ]t then passes around a highly polished take-off roll 36, whereby its upper surface is polished, and is led by a roll 62 to a seasoning or drying point. The point at which the web is stripped from the roll 20 may be so chosen that a loop 63 forms, whereby (a) any strains and stresses resulting from the direct stripping from the roll 20 are reduced to a minimum and (b) the loop allows access of solvent vapours to the web and roll 36 to facilitate polishing. The rolls, or the roll 36 only, may be replaced by a polished belt. Solvent vapours may be directly applied to the upper surface of the web, or to the polishing surfaces, or a casing 64 may enclose the rolls. The rolls 20, 36 are preferably positively driven, are hollow, and are watercooled by means of axial passages 60, 61. Water jackets 50; 51, 52 heat the extrusion head.
