Title: Improvements in or relating to electrical heating elements of the panel type
IPC: H05B3/16
Filed: 1955-12-22
Abstract: 801,654. Electric heating panels. DULRAE, Ltd., STEELE. W. H., and LEA, N. J. Dec. 22, 1955, No. 36792/55. Class 39(3) A heating panel comprises two layers of rigid asbestos cement board united by a thin layer of a resin bonded asbestos, or other resin bonded material activited to unite the boards with sinuous lengths of resistance wire or tape between and insulated from the asbestos cement. Two resin bonded asbestos sheets may form the insulation or the resistance wire is insulated e.g. by layers of glass silk or a coating of enamel or plastic e.g. nylon. The ends of the wire are connected to flat terminal strips or tags held between the rigid boards. The resin-bonded material may be laid along the margins only of the opposed boards, the sinuous wires between the margins being then insulated either by insulations thereon or by layers of insulation e.g. glass silk or paper impregnated with resin between the boards. A number of panels thus assembled may be stacked in a single or multi-daylight heated press, if necessary interleaved with heaters of the panel type and subjected to heat and pressure to cure the resin-bonded material and reduce its thickness from 1/16 in. to 0.016 in. The boards are flat or corrugated before assembly. Specification 661,155 is referred to.

Abstract: 1316215 Data keyboards NATIONAL CASH REGISTER CO 5 Aug 1971 [14 Sept 1970] 36820/71 Heading G4H A keyboard 10 and read in system is adapted such that data from a particular key may be read in before the preceding key(s) have been released and comprises 16 keys K1-K16 each associated with a stage B1-B16 of a first shift register 12, the last stage B16 of which is connected to the first stage C1 of a second shift register 14 having stages C1-C16, the apparatus being operable cyclically under the control of a clock 15 and a strobe signal marking the starts of successive cycles and being coincident with every 16th clock pulse, the outputs of the stages C16 and B16 being taken to a logic circuit 19 producing an output only when the stage B16 is in a "1" state and C16 a "0" state, this output enabling AND gates 18 to read into a store 22 the instantaneous values in a 4-bit recycling counter 16 incremented by the clock 15, and to cause the contents of the store to be applied as input to the computer 33. The strobe signal is derived from the "all zero" state of counter 16 via circuit 17 and in operation when a key is depressed a binary "1" is applied to, e.g. the nth stage of register 12 upon the next strobe pulse and this "1" bit is moved through the stages until after (16- n) instants it is inserted at B16 when the conditions at 19 are satisfied and the code presently in the counter 16 is read out. If the key remains depressed during a subsequent cycle, after (32-n) instants it may be seen both B16 and C16 are in the "1" state and the key depression is ignored.

Abstract: 1,031,219. Umbrellas. A. KORTENBACH, H. J. WORRING, T. SCHULTES, F. WORRING, K. KORTENBACH, D. WORRING. Sept.18, 1963 [Oct. 6, 1962], No. 36826/63, Heading A4P. Telescoping stick members of a pocket umbrella are held n extended and collapsed position by a locking pawl 23 which is displaced from lockng position to release positon and vice versa, and retained in these positions, by a release member 28 longitudinally displaceable within the stick. A circular end 22 of the pawl is loosely mounted .n a similarly shaped slot 20 in an end piece which may be if plastic and which is inserted in the inner stick section. On movement of the member 28 towards the handle an edge 24 of the pawl is engaged by a web 27 of the release member and a projection 26 is entered into superposed apertures in the outer and inner stick members and locked therein. On movement of the member 28 away from the handle a sloping edge 25 is engaged by a projection 29a and withdraws the projection 26 from the apertures and the web 27 is, simultaneously, raised to permit pivotal movement of the pawl. The release member is moved by a pull rod 31 having bent ends 32, 34 engaged in bores 33, 35 in the release member 28 and in a plunger 36 which is displaceably mounted in the inner stick member, has a slot 39 and which may be of plastic extruded round a pressure pin 37. A pin 40 to which a handle may be attached is secured in opposite sides of the inner stick member and passes through the slot 39 to limit movement of the plunger 36. A compression spring 41 bears on the member 10 through an intermediate member 42 (Fig. 1, not shown) to hold the locking parts in locked position and the plunger 36 is operated against the action of the spring for release of the locking parts in telescoping the stick parts. A locking nose on the slide bears against an end 44 of a slot 43 when the umbrella canopy is closed, rotation of the stick parts is prevented by an indentation in the outer stick part engaging a groove in the inner stick part, and separation of the stick parts is prevented by a spring- urged stop pin in a bore in the inner stick part engaging the end of the indentation through openings in both the stick parts. In a modification the slot 43 is replaced by a shorter opening and the intermediate member is displaceably mounted, is connected to the plunger by a second pull rod, and has a bevelled edge for engagement through the shorter opening with the locking nose of the slide when the canopy of the umbrella is closed. In a further modification the pawl 23 is pivotally mounted by a pin in a plastic end piece and the stop pin is urged by a leaf spring.
