Title: Improvements in electric overload circuit breakers
IPC: H01H77/10
Filed: 1920-04-13
Abstract: 165,563. Bolton, R. A. R. April 13, 1920. Automatic circuitbreakers; sparking, preventing. - In a circuit-breaker, the interaction of the currents in the movable and fixed parts tends to separate them and to blow out the spark between the contacts, which are constructed as arcing horns. A single-break form is shown diagrammatically in Fig. 1 and a doublebreak in Fig. 3. A partial magnetic circuit of iron may be arranged outside and adjacent to the loop formed by the fixed and movable current carrying members to augment the blow-out action. In the circuit-breaker shown in Fig. 4, the fixed contact is constituted by the turned-up end b of a strap conductor, which is bent into one or more coils wound round a three-sided core k. The movable conductor, pivoted at o and bent at its contact end to form a contact horn, is normally retained in the closed position by a spring-controlled magnetic latch q which is withdrawn on overload by the core u magnetized by the current in arc of the conductors. When released the contact arm is moved to the off position by the reaction between the coils, and the arc is blown out at the horns by the field produced by the loop and by the coils.

Title: Jointing thermoplastic-insulated cables
IPC: H02G15/196
Filed: 1944-06-01
Abstract: 587,580. Cable joints. TELEGRAPH CONSTRUCTION & MAINTENANCE CO., Ltd., DEAN, J. N., WILSON, H. F., and COOK, E. I. June 1, 1944, No. 10565. [Class 38 (i)] Two lengths of cable insulated with the same or different thermoplastic dialectric materials which are not wholly composed of polyisobutylene are joined together by a jointing medium consisting of or comprising polyisobutylene. Several examples are shown, such as that in Fig. 1, in which the insulation of the cables is respectively deresinated gutta percha G and polyethylene P. The insulation is pared down to a cone shape, or is heated and pulled back, and a layer of polyethylene tape 1 carrying an adhesive layer or layers of polyisobutylene is wound on the reduced portion and for about an inch on either side of the outer ends of the cones. Other examples describe methods for jointing different combinations of insulation, e.g., polyethylene to polyethylene, polyethylene to deresinated balata, &c. In another example, Fig. 5, in which gutta percha is joined to polyethylene, the gutta percha G is covered with a gutta percha-polyisobutylene tape 4 and the polyethylene P with a polyethylene-polyisobutylene tape 1. The whole is then covered with polyisobutylene tape 2, a layer of polyethylene-polyisobutylene tape 1 and an outer layer of polyethylene tape 31. Where commercial gutta percha or balata is to be joined to polyethylene, an intermediate section of deresinated gutta percha or balata respectively is placed between the two sets of insulation, Fig. 6 (not shown). The applied materials may be welded together by heating the joints by a spirit lamp or by covering the joint with a metal tube which is heated to between 130‹C. to 160‹C, and which, after cooling, is stripped off, Fig. 8 (not shown). In Fig. 9 (not shown), a number of joints are covered with hot lead which is stripped off when cool. In another method, Figs. 7, 7A, 7B (not shown), the joint is covered with proofed tape and is placed in a heated mould where a covering of polyethylene is applied. The ends of the mould are cooled gently, and the polyethylene and the proofing are removed.

Title: Improvements in or relating to directive radio systems
IPC: H01Q25/00
Filed: 1944-06-05
Abstract: 589,136. Wave guides; aerials. WESTERN ELECTRIC, CO., Inc. June 2, 1944, No. 10688. Convention date, June 5, 1943. [Class 40 (v)] In a directive radio system, a receiver or transmitter is connected through a switch to transmission channels connected to different points on an antenna system comprising at least one wave-guide for radiating and collecting waves. Fig. 1 shows a lobe switching arrangement for radar comprising a transceiver I connected by a coaxial line 2 to a main wayeguide 5, the end of which communicates by apertures 14 with two chambers 9, 10 separated by a partition 8 formed with an aperture 11 and rotatable detuning vane 12. Chambers 9, 10 communicate by apertures 21 with respective branch guides 16, 17 which connect with a guide 23 at points 29, 31 at a quarter wavelength from the ends. The guides 16, 17 and 23 are filled with polystyrene, and guide 23 is provided with transverse slots 26 to form a broadside antenna. The slot spacing is arranged to give a direction of maximum radiation at an angle # to the perpendicular to the longitudinal axis of the guide, # being positive or negative according to which end the energy enters or-leaves the guide. Thus, with chambers 9, 10 alternately detuned by rotation of vane 12, energy from transmitter 1 is alternately fed through guide 16 or guide 17 to opposite ends of guide 23 to give alternate lobes at an angle # to the broadside position. The reception pattern is similarly switched. The coaxial line 2 may include a flexible joint 37 to enable the antenna system to be rotated to face a target, this being indicated by the receipt of echo pulses of equal intensity. In Fig. 3, a transceiver 1 feeds through coaxial line 2 and main guide 5 to chambers 7 alternately detuned by rotating vane 12, which connect through guides 42 and coaxial lines 41 to opposite end of wave-guide antennas 23 similar to that in Fig. 1. The guides 23 are angularly displaced to give a desired angle between alternate lobes. Alternatively, the guides may be fed at adjacent ends. The Specification as open to inspection under Sect. 91 also includes the following matter. Fig. 5 (Cancelled) shows an antenna for simple broadside action, comprising a waveguide 45 filled with polystyrene and provided with transverse slots 26 arranged one wavelength apart, and facing a parabolic reflector 47. The antenna is energized by transmitter 1 through coaxial line 2. A similar broadside effect can be obtained by an air-filled guide having a longitudinal slot, and energized either at the middle or at one end, Figs. 6, 7 (Cancelled), not shown. Fig. 8 (Cancelled) shows an antenna for end-on effect comprising a wave-guide 80 filled with polystyrene and formed with a longitudinal slot 81, 82 in each side. This subject-matter is not contained in the Specification as accepted.

[Also in Division F1] A multiple injection manifold for a ram-jet unit or for a turbo-jet reheat burner comprises a ring made from two straight bars of the crosssection shown in Figs. 3 and 4, and drilled to form passages 11, 12. Each bar is then bent to form a half-ring 14, Fig. 9, and connected to the other by sleeves 14a and welds 15 to form a complete manifold ring. The ring is drilled and tapped to receive injectors 16, and a duct 17 or 18 is bored to communicate each injector with one of the passages 11, 12. Finally, the manifold ring is drilled to receive supply pipes 19, 20 which are welded to it. Fuel can be supplied independently through pipe 19 to those injectors which communicate with the passage 11 and through pipe 20 to those injectors which communicate with the passage 12. In a modification, the injectors are inserted into untapped holes and retained by caulking the margins of the holes over shoulders formed on the injectors. In an alternative construction, a ring 23, Fig. 12, is forged in a single piece and machined to provide annular channels 11, 12. The resultant annular walls 25, 26 and central partition 24 are initially parallel to each other but the walls 25, 26 are subsequently deformed by a tool 27 and welded at 28 to the partition to form annular passages 11, 12. Uniformly spaced holes are drilled and tapped to receive injectors (not shown), ducts 29, 30 being provided to communicate each injector with one of the passages 11, 12. Holes are drilled in the ring 23 to receive supply pipes communicating with the passages 11, 12. In the case of the supply pipe 31, Fig. 13, for passage 11, three holes are drilled, as shown, and the pipe is welded to the ring 23 at two of the holes, the third hole (which serves as an access hole during the welding) being subsequently closed by welding a plate 33 over it. Two manifold rings similar to the ring 23, one being of smaller diameter than the other, may be arranged coaxially with one another, with their respective passages 11, 12 connected in parallel to the fuel supply pipes.
