Title: Improvements in flexible conduit
Inventor: DAGGETT FREDERICK KIMBALL
IPC: B29D23/00
Filed: 1963-05-10
Abstract: 965,640. Flexible conduits. FLEXIBLE TUBING CORPORATION. May 10, 1963, No. 18647/63. Heading F2P. A flexible conduit comprises a helix 10 of wire having a coating 11 and covered with a helical wrapping 12 of elastomeric strip material, the coating and the plies being fused together. The elements are wrapped about a mandrel, tension, heat or solvents, or all three, being applied during the wrapping. Heating is by induction from the mandrel or external radiant heat. As shown, the pitch of the wire helix and that of the covering strip are the same and the strip is wide enough to cover five turns of the helix, whereby the cover is five plies thick. The coating becomes flattened as shown at 11<SP>1</SP>, resulting in a smooth inside surface of the conduit. The wire 10 is pre-curved before use by an amount to result in desired conditions of compressibility and extensibility of the conduit. The plies of the fabric fuse together only partially and so the tension in the covering strip varies across its width and results in increased flexibility of the conduit.

Abstract: 854,883. Nuclear reactors. ENGLISH ELECTRIC CO. Ltd. June 7, 1957 [June 15, 1956], No. 18708/56. Drawings to Specification. Class 39(4). In a reactor having a core comprising layers of graphite blocks in which fuel element channels extend perpendicular to the layers, the channels receiving a plurality of fuel elements arranged end-to-end, the pitch of the layers equals the pitch of the fuel elements. Since the fuel elements either have support means co-operating with recesses in the channels as disclosed in Specification 854,882 or have electric contact means co-operating with contacts in the channels as disclosed in Specification 835,410, the pitch relationship permits similar blocks to be used in the several layers. Reference has been directed by the Comptroller to Specification 781,648.

Abstract: 978,321. Electric switches. TUNG-SOL ELECTRIC Inc. May 25, 1961 [Feb. 6, 1961], No. 18969/61. Heading H2B. A hot-wire-actuated snap switch comprises a resilient rectangular plate 2 having two longitudinal slots 4 defining a waisted central vane 6, the plate being deformed adjacent each vane end 14, 16 to bias it outwardly from the plane of the strips 8 on the outsides of the slots, each strip being shortened relative to the vane by crimps 10. The plate is welded or otherwise affixed, at one end, to a conducting frame 18 in which a contact 32 is insulatedly mounted so as to co-operate with a vane contact 20, whilst an L-shaped anchor member 22 secured on the convex frame mounted vane part is connected by a thermally extensible control-currentcarrying wire or ribbon 28, to an upstanding frame portion 26, the member 28 being mounted in an insulating bead 24, at the vane end, and so tensioned as to bow the vane central portion oppositely to its biased ends, the co-operating contacts being " made " when the control current causes a reduction in tension of the member 28. During operation of the switch the radii of curvature of the vane parts vary, but no alteration of sign occurs. The above snap switch may be combined with a magnetic relay on a common insulated pin mounted base, so as to form a lamp flashing device. Thus, when the wire 21 is cold and hence the contacts 20, 32 are open, a current flows through frame 26, the wire 28, a ballast resistor 30, a relay winding 34, and a lamp 36 intended to be flashed. Due to resistor 30, the current will be insufficient to energize either the relay 34 or lamp 36, but will heat the wire 28, causing it to expand and hence close the contacts 20, 32. Both the wire 28 and the resistor 30 are now shorted so that, the relay 34 will close contact 38 to light a pilot lamp 40, the lamp 36 will light, and the wire 28 will cool, so opening the contacts 20, 32 to repeat the cycle. The ballast resistor 30 may be shielded from the wire 28 by a mica plate. A " stop " for the member 9 in its de-energized position may be utilized as a contact which co-operates with a further vane mounted contact if a thrust over contact configuration is required.

The inner portion of the stud is oblong in cross section and the inner bore of the sleeve is formed with two internal diagonally located axially extending ribs 21, 21a which prevent the stud from rotating through more than 90 degrees in the socket. The inner bore is also formed with two diagonally located stops 22, 22a which prevent accidental rotation of the stud back from the fastening position. The fastener can be used for attaching a backboard to a radio or television cabinet and in such use the sleeve is received in a bore in the cabinet so that when the stud is rotated the wall of the outer bore is compressed between the lugs and the bore in the cabinet to retain the fastener in position. The stud extends through an aperture in the back panel and rotation of the sleeve relative to the cabinet is prevented by a straight edge 24 of the flange which abuts a rib of the cabinet.
