Title: Improvements in rotary switches for use in automatic telephone systems
IPC: H01H67/06
Filed: 1950-12-13
Abstract: 672,011. Automatic exchange switches. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Dec. 13, 1950 [Dec. 16, 1949], No. 30435/50. Class 40 (iv). In a rotary switch, the contact bank 1 is fitted between two side plates 2 while the wiper carriage 9, which is rotatable about a shaft 6, is mounted between two other plates 3 together with its driving means so that when the switch is assembled each end of the shaft 6 is clamped between a plate 2 and a plate 3. The plates 2 carry a fixed arm 22 and a spring-urged rotatable arm 27 between which is held a stud 26 adjustably mounted on an arm 25 secured to the plates 3, the resultant force on the stud 26 being directed towards the shaft 6 so as to hold the two parts of the switch together. Resilient strips 19, 20 are secured to the shaft 6 and carry studs 21 which engage slots in the plates 3, allowing a limited movement of the shaft 6 relative to the plates 3. In a modification (not shown), the wiper carriages of a number of switches are selectively coupled to a common driving means.

IPC: B60G11/02
Filed: 1922-08-22
Abstract: 193,161. Stott, J. H. Aug. 22, 1922. Laminar springs.-A laminated vehicle spring is mounted so as to give easy springing when working alone during the earlier portion of its deflection and stiffer springing during the later portion when at one or more predetermined points it is controlled at one end by a continuous stop fixed to the chassis, and at the other end by a continuous stop connected to the chassis by parallel swinging links so as to follow the longitudinal movement of the spring. In a modification, a continuous stop may be carried by the spring itself at one or both ends thereof. The stops are of considerable length, such as a quarter or third of the length of the spring. The stop AB is fixed to the chassis J and the stop CD is connected to the chassis by parallel links CE, DF so as to follow the longitudinal movement of the spring from its unloaded position, Fig. 1, to the fully-loaded position, Fig. 3. In the modification shown in Figs. 6 and 8, the stops AB, CD are at one end attached to the spring eyes, and at the other end to points nearer the encastrement G by adjustable links BK, DH. The stops in this modification may be in two or more portions hinged together so as to come into operation at different points in the deflection, each hinge joint being connected to the spring by links similar to BK, DH; rubber-covered stops or spring buffers P, N on the chassis may come into action just before the position of maximum deflection as shown in Fig. 8. The stops may be straight or curved and may be formed with side flanges. Specifications 4412/07, [Class 52, Furniture &c.], and 14113/13, [Class 8 (i), Air and gases, Compressing &c.], are referred to.

Abstract: 299,730. British Thomson-Houston Co., Ltd., (Assignees of Kingdon, K. H., and Tonks, L.). Oct. 29, 1927, [Convention date]. Vacuum tubes.-In electron discharge devices, microphonic noises due to vibrations of helically coiled filamentary cathodes are prevented by so mounting the filament on its supports that a rubbing contact is produced between the filament and at least one of the supports at points between the ends of the filament which is rigidly secured at its end to the support. In the form shown in Fig. 2, the filament 4, formed by winding it on a 15 mil mandrel, is spot welded at its ends 19, 20 to nickel wires 14, 18, of about 10 mils in diameter, which project into the filament for a. short distance so that rubbing contacts are made therewith. In a modification, Fig. 3, thimbles 21, secured to the ends of the wires 14, 18, are made slightly larger internally than the filament spiral 4. In the valve shown in Fig. 1, the wires 14, 18 are carried by a leadin wire 15 and an extension 17 on a lead-in wire 16. The filament 4 is surrounded by a grid 3 carried by a plate 5, supported by wires 7, 8, and spaced from the anode 2 which is carried by wires 9, 10.

[Class 38 (v)] A thermal switch has a snap - action cantilever blade spring 10 which is slotted at 13, 14 and deformed so as to have two outer tension members and an inner bowed compression member 15. The thermal element consists of an outer metal tube 6 containing an inner low-expansion alloy rod 7 which are fixed together at their lower ends. The upper end of the tube 6 is screwed to the switch-base 8 and the upper end of the rod 7 carries a stirrup-like member 9 having an adjustable bolt 11 with an insulating part 12 which bears on the compression member 15. At the required temperature, the pressure of the part 12 causes the spring 10 to snap over and open the contacts 17, 18, Fig. 5, movement of the contact 17 being limited by a stop 21 so that when the temperature falls the spring snaps back again.

Abstract: 136,826. Rabbidge, P. Dec. 19, 1918, [Convention date]. Void [Published under Sect. 91 of the Act]. Transformers; commutator switching-arrangements.-Two or more transformers of the form shown in Figs. 1 and 2 are used in combination. The primary coils of each transformer are divided into sections D<1> - - D<6>, the current in each section being reversed separately for the purpose of varying and reversing the flux through the secondary coils E. In the arrangement shown in Fig. 3, three transformers are used, and the sections are connected in such a manner that the first section of the primary of transformer 1, the second section of the primary of transformer 2, and the third section of the primary of transformer 3 are reversed simultaneously, the other sections being reversed in corresponding order in succession. The primary sections are connected to commutator segments F<1> - - F<6>, which receive current from brushes H, H<1>. The sections E<1> - - E<6> of the secondary windings are connected to segments G<1> - - G<6> from which current is collected by brushes J, J<1>. On rotating the apparatus, the flux through the secondary sections of each transformer is reversed at successive moments in each half revolution. The same result may be obtained by rotating the brushes, three transformers of the form shown in Fig. 1 being used, or by supplying the primary sections with three-phase current without commutation.

Title: Improvements relating to cellulose derivative moisture-proofing compositions
IPC: C09D101/18
Filed: 1935-11-16
Abstract: A moisture-proofing composition particularly for cellulose, cellulose derivative, gelatine &c. films or foils, consists of a solution in an organic solvent of nitrocellulose or other cellulose derivative, a plasticizer, chlorinated rubber and a wax, the amount of the wax exceeding 10 per cent of the solid constituents of the composition. Amounts of wax of 14 per cent may be employed while still obtaining a transparent and glossy coating, and this amount may be considerably increased if a gum or resin is included in the composition, regard being then had to any wax brought in by the gum or resin.  The added wax may be paraffin or like hydrocarbon wax.  Suitable proportions of the constituents are: chlorinated rubber, 10--40 per cent of the wax; gum or resin, 80--250 per cent of the combined weight of wax and chlorinated rubber.  In preparing the composition, the nitrocellulose and the chlorinated rubber and wax are first dissolved separately, the wax being dissolved simultaneously with or subsequent to the chlorinated rubber; the gum or resin is usually dissolved and incorporated with the nitrocellulose or in the solvent for the chlorinated rubber either before or simultaneously with the wax; the solutions are finally mixed.  In examples, the following solutions are mixed together: nitrocellulose, dimethyl phthalate, diethyl phthalate, triphenyl phosphate, dammar resin, ethyl acetate and toluene, and a chlorinated rubber and wax in solution in toluene; nitrocellulose, triphenyl phosphate, dimethyl phthalate and ethyl acetate, and dammar resin, chlorinated rubber, wax in solution in toluene.
