Filed: 1924-03-18
Abstract: 232,016. Dougall, J. March 18, 1924. Coin-slit closing-devices. - A safety device for coin-freed meter mechanism of the type described in Specification 214,077 comprises a shutter 11. Fig. 3, rigidly attached to the operating handle on the inside of the price-changing plate 3. The shutter works in a recess 10 in the face of the coin-carrier disc 4, Fig. 2, and itself forms the driving means for the coin-carrier. Anticlockwise movement of the handle causes the edge, 12 of the shutter to engage the edge 13 of the recess thereby moving the carrier 4 until a projection 14 thereon engages a stop 15 on the price-changer. The coin is then inserted and the first. movement of the handle in the clockwise direction causes the shutter to close the coin slot. Driving connection is established between the edge 16 of the shutter and the edge 17 of the recess 10. The edge 18 of the slot 2 in the price changer and the edge 16 of the shutter are chamfered to facilitate the entry of the coin into the coin carrier.

Title: Improvements in or relating to coil loaded submarine signalling cables
IPC: H02G15/14
Filed: 1932-03-08
Abstract: 398,206. Coil-loaded submarine cables. STANDARD TELEPHONES & CABLES, Ltd., RILEY, T. N., HUGHES, R. L., and COLE, R. A. L., Connaught House, Aldwych, London. March 8, 1932, No. 6963. [Classes 36 and 37.] The coil boxes of a coil-loaded submarine. cable are formed with a diameter equal to that of the cable core, so that the lead sheath and armouring of the cable may extend continuously over the coil boxes. The boxes, which are preferably formed with two flat sides to allow room for the passage of the coil leads, may be connected together in chain form by spring links, rubber spacers through which the connecting links pass being disposed between adjacent boxes. The end boxes of the chain are secured to the cable by connection to a plurality of insulated wires which are laid up round the centre component of the cable and extend throughout the entire length thereof or, at least, for a sufficient distance to get an adequate friction grip. The coil boxes, which may be of metal and coated with hard rubber, are preferably shaped, as shown in Fig. 1, being adapted to fit within the cable sheath with their longer dimension along the cable axis and are formed in halves b secured together by bolting. A cavity 6 is formed in .each half to accommodate the loading coil which is secured therein with its axis perpendicular to the flat sides 12 of the box by rubber bushes inserted in' apertures 1 which are formed in the sides 12 and through which the coil leads pass. The contacting faces of the halves are formed with recesses 3 to receive the ends of the spring connecting-links which are retained therein by bolts passed through holes 4. These bolts also secure the two halves of the box together. In order that the chain of boxes may be uniformly rigid in all directions, consecutive boxes may be given a twist around the cable axis so as to lie in helical form. The direction of the helix may reverse at intervals. Fig. 4 shows boxes 7, 8, 9 arranged helically within a sheath 13 and spaced by skewed rubber blocks 10, 11. The boxes are connected together by spring links 14. The squads of the cable are connected to the coil by small-gauge textile- or paper-insulated wires which are laid up in groups in the helical space between the coil boxes and the cable sheath. The whole joint is then padded out to the cable diameter, dried, and sheathed together with the attached cable lengths. The unloaded lengths are also dried and sheathed and jointed to the loaded lengths, the whole then being stripped and lead-sheathed in a continuous length.

Title: Improvements in "seal-off" air or gas blast electric circuit breakers
Inventor: ROXBURGH ALBERT
IPC: H01H33/32
Filed: 1959-02-27
Abstract: 936,797. Gas-blast switches. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Feb. 26, 1960 [Feb. 27, 1959], No. 6978/59. Class 38 (5). In a gas-blast circuit-breaker such as that described in Specification 821,069, wherein the contacts are maintained open by the gas pressure, the valve which exhausts the contact chamber for contact closing is pressure operated through a restricted passage so that it can be sealed off from the contact chamber by the final opening movement of the blast valve and it does not operate until the closing movement of the blast valve is completed. As shown, downward movement of the operating rod 18 moves the blast valve 11 to open ports 8, allowing pressure gas to flow from the receiver 1 into the contact chamber or chambers through an insulator 2. Gas also flows to a valve piston 23, but this is not operated since the flow is restricted by a passage 28 and the lower end of the valve 11 seats on an annular ring 27 to cut off this flow. When the rod 18 is moved upward the restriction of pressure build-up in the space 30 due to the passage 28 allows the ports 8 to be closed and sealed at 17 before the valve piston 23 is moved downward to open ports 9 to the atmosphere and discharge the interior of the valve 11 and the contact chamber. A spring 26 recloses the valve 23 as the pressure falls. A space 31 and passage 32 act as a dashpot for the valve 11.

Patent GB-818109-A (GB)
Title: Method for preparing butyl rubber emulsions
Inventor: HUNTER EDWARD ALLEN
IPC: C08J3/07
Filed: 1957-03-05
Abstract: Latices of butyl rubber are formed by emulsifying a solution of the rubber with water in the presence of a fatty acid soap containing 12 to 24 carbon atoms, polyvinyl alcohol and a polyoxyethylated alkyl phenol containing 5 to 12 ethylene oxide units and in which the alkyl group contains 8 or 9 carbon atoms, then removing the butyl rubber solvent by stripping under vacuum at a temperature above 100 DEG  F. The butyl rubber is a copolymer of isobutylene with a minor amount of a multiolefin, e.g. butadiene, isoprene, dimethyl butadiene, dimethallyl, myrcene or allo-ocimene, which is prepared at a low temperature in the presence of a Friedel-Crafts catalyst.  The solvent for the rubber may be hexane, heptane, octane, isooctane, nonane, decane, naphtha or aromatic hydrocarbon fractions, benzene, toluene, Varsol, cyclohexane, cyclohexene, carbon tetrachloride, trichloroethylene, carbon disulphide or methyl ethyl ketone.  The soap may be derived from oleic, palmitic, linoleic or stearic acid and sodium, potassium, lithium, rubidium, caesium or ammonium hydroxides and may be made in situ.  The composition is mixed in a suitable device, preferably a high-speed sonic mixer, at a raised temperature, and preferably in the presence of a small excess of hydroxide sufficient to raise the pH to 10 or 11.  In an example, resorcinol and formaldehyde were added to an emulsion of the above type and a rayon tyre cord was coated with the composition. Comparative examples are given of forming latices of butyl rubber in the presence of sodium lauryl sulphate, ammonium alginate, carboxymethyl cellulose, a polyoxypropylated glycol and a polyoxyethylated octyl phenol containing 4 ethylene oxide units together with one or two of the three essential components of the emulsifying system of the invention.

Title: Improvements in or relating to toy race courses
IPC: A63F9/14
Filed: 1925-03-19
Abstract: 241,099. Wade, H., (Mills Novelty Co.). March 19, 1925. Race games, mechanical.- Toy figures 1 . . 6 resembling race horses are mounted on parallel endless tracks B which may be undulated, and are propelled along the tracks by projections 1<a> .. 6a on a band C. The sets of projectors 1<a> . . 6a are arranged in varying sequence, so that when the horses are propelled beyond the upper reach of the band C and travel along the lower reaches 7a of the tracks B, the projections engage the horses in a different order so that the winner of a race is uncertain. The horses are propelled along the part of the track out of reach of the projections by means of a bar 13 extending across the tracks and carried by a band D, the supporting rollers of which are at a lower level than the rollers carrying the band C. The bands C, D are driven by a motor E, the drive of the band D being through a clutch. The apparatus is preferably set in motion simultaneously with an automatic musical instrument, which may be coin-freed. The electrical connections are shown in Fig. 7. A coin dropped into the shoot N<2> closes a switch N and so energizes an electromagnet K<1> so as to close the circuit of the motor E, which continues to operate until a member 23 on the band D closes a contact 21. The magnet K<2> is then operated so that the switch K breaks the motor circuit. The horses are on the upper reach of the tracks and visible through a window A<3> when the race starts and are carried by the projections 1<a> . . 6<a> to the left of the apparatus. After they leave the projections the bar 13 overtakes them and carries them along the lower reach 7a to the right of the apparatus. Meanwhile, the belt C may have been stopped momentarily owing to the circuit of a magnet J which operates the clutch F having been closed by the contacting of a strip 18 corresponding to one note of the instrument with a bar M. While the horses are in sight, the note-playing device is prevented from opening the clutch F by the projection 23 engaging a pivoted lever 25a to close contacts 24, 25 and so cause a magnet L<2> to open the switch L, putting the magnet J out of action. The switch L is adapted to remain in either its open or closed positions until next energized. When the horses are again driven by the projections on the belt C, their new order is uncertain, owing to the movement of the belt while the horses passed out of sight. The end of the race is caused by a projection 23 on the belt D striking a pivoted lever 22a to close contacts 21, 22. A magnet L<1> is simultaneously operated to bring the switch L to closed position on the stud 19. The switch L controls the magnet J, and thus the magnet has its circuit closed in readiness for the next operation. The machine frame A, which carries the contacts 22, 25 forms part of the electrical circuit. Specification 234,258, [Class 88 (ii), Music &c.], is referred to.

Abstract: 584,934. Soldering magnets &c. STANDARD TELEPHONES & CABLES, Ltd., GRACE, B. B., and MILLS, E. April 28, 1944, No. 7984. [Classes 83 (ii) and 83 (iv)] In soldering or brazing, one or more of the surfaces are coated with a metal or metal-containing compound and are then placed and maintained in contact under controlled pressure and subjected to a controlled cycle of electric heating and cooling, while adjacent parts remain at a temperature below which any desirable physical or mechanical properties thereof are permanently altered. The coating may consist of tin, cadmium, nickel, copper, zinc, or alloys such as tin-zinc-nickel or a number of coatings may be applied such as tin on nickel, tin on cadmium or silver on copper. The base material may be ferrous or non-ferrous, beryllium-copper or a non-metal such as a ceramic material. The coating may be applied to a metal base by electro-plating, or by a metallic paint reduced to metal by heat after application, or to a non-metallic base by a metallic paint such as by applying a silver salt solution and heating to a temperature at which the solution is reduced to a metallic film. The joint may be effected between two pre-coated bodies or between a pre-coated body and another body. The parts may be resistance heated between a pair of preferably water-cooled carbon graphite, or metal electrodes, or heated by electric induction. Permanent magnets of cast or sintered aluminium-nickel or aluminium-nickelcobalt for electric measuring instruments, moving coil or electro-magnetic microphones and receivers, telephone relays &c. may have their polepieces 3 and bodies 1 electroplated with tin, and then assembled in a jig of oxidized aluminium bronze and pressed between a pair of water cooled carbon electrodes at a temperature between 275‹ C. and 410‹ C. until a value of 750 lbs. per sq. in. is reached, pressure being applied prior to the heating cycle. When the temperature falls to a predetermined value, e.g. 150‹ C., the pressure is removed. According to the Provisional Specification an electroplated coating of tin may, prior to soldering, be coalesced by heat treatment at a temperature of 230‹ C. in a controlled atmosphere. The coating also may be applied by spraying. Soldering may be effected in an atmosphere of cracked ammonia, hydrogen or burnt town's gas.
