Title: Improvements in or relating to electric communication cables
IPC: H01P3/02
Filed: 1944-10-20
Abstract: 584,153. Electric cables. STANDARD TELEPHONES & CABLES, Ltd., and SCOTT, T. R. Oct. 20, 1944, No. 20343. [Class 36] An inner conductor is separated from an outer conductor or sheath by air-spaced bodies of expanded organic insulating material. In Fig. 1, the inner conductor 1 and outer conductor 2 are separated by beads 3, of expanded polystyrene, polythene, polymerized 2.5 dichlorostyrene, or polytetrafluorethylene made in two portions and cemented together by polystyrene dissolved in monomeric styrene. The remaining space may be filled by gas, such as nitrogen or helium, at super-atmospheric pressure. In Fig. 3, the beads are replaced by three layers of tape, which may be trapezoidal in cross-section, made of expanded material and laid helically about the inner conductor 1, the spaces 7 being filled with gas. Alternatively the conductors may be separated by cords of the expanded material. Initially, the gas pressure is raised to the required amount, so that gas enters the honeycomb structure by diffusion through the thin partitions, and longitudinal channels may be provided in the insulation immediately adjacent to the conductors to facilitate permeation of the gas. When the invention is applied to a cable with an inner conductor and an outer sheath of lead or polyisobutylene loaded with carbon black, rubber or synthetic rubber, a layer of unexpanded material such as a polymer of ethylene or polytetrafluorethylene, a copolymer of styrene with butadiene or rubber, a copolymer of dichlorostyrene with butadiene or rubber, chloroprene, or butyl rubber is applied to the conductor by extrusion. Specifications 448,486 and 553,569 are referred to.

Title: An improved machine for sorting and issuing coins
IPC: G07D9/00
Filed: 1927-08-13
Abstract: 276,015. Prochazka, R. J. Aug. 13, 1926, [Convention date]. Coins and the like, separating and sorting; money-delivery apparatus. -A machine for sorting coins according to size, and for delivering a selected number of sorted coins on the actuation of one of a series of keys, comprises means for feeding the coins by a rotatable disc one by one to an inclined runway where the coins are deflected by projections to appropriate cylinders. The coin-delivery means is formed with a device for preventing accidental delivery of more than the required number of coins, and with a device for locking the ejectors when the cylinders are nearly empty. Coins are fed to a receiver 3 by a tiltable, table 1, the coins entering recesses 5 at the bottom of an inclined rotating disc 4 which carries the coins to a channel 6. The coins, discharged one by one into the channel 6, pass to a sloping plate 9 above which are arranged, projections 10 at different heights. The rolling coins are defected by the appropriate projections 10 into cylinders 11. Nested tongues 13', 13<11>, 13<111>, at the foot of each cylinder are actuated to discharge coins by keys 17<1>, 17<11>, 17<111>, each of which is carried by a separate lever 18 rotatable about a shaft, 19 and linked to a lever 21 and arms 22, as shown in Fig. 2. The arms 22 are connected to the tongues 13<1>, 13<11>, 13<111>, and the actuaton of a key 17<1> pushes forward the tongue 13<1>, the actuation of a key 17<11> pushing forward the tongues 13<1>, 13<11>, and the key 17<111> pushing forward the tongues 13', 13<11>, 13<111>, to eject one, two. or three coins respectively from a cylinder. To prevent accidental delivery of more than the required number of coins, a, pin 27, normally blocking the ejection of the coins, is formed with a slot 28 and is adapted to be raised by a pivoted lever 29 which is actuated by a cam on the ejector tongues 13<1>, 31<11>, 13<111>, so that the required number of coins can pass through the slot 28. The ejector tongues are locked, when a cylinder is empty, by a pivoted spring-controlled lever 36, Fig. 5, formed with a toe 35 which moves through a slot 34 in the cylinder wall when the number of coins in the cylinder falls to less than three. The movement of the lever 36 frees a pivoted spring- controlled arm 43 from a notch 42 in the lever 36. the arm 43 rocking to engage a pin 45 in openings 46 in the tongues 13<1>, 13<11>, 13<111>.
