[Also in Division F2] A method of making endless drive belts or conveyer belts includes a first step wherein a narrow bat of one or more carded webs with their fibres, some of which are meltable fibres, orientated in the longitudinal direction of the bat, is needled in a needling machine, and a second step wherein the bat 7 is wound over two rollers 3, 4 either straight or, as shown, with a lead equal to a fraction of the bat width, the overlapped windings being needled together in a needling machine 5, after which hot air is blown through the windings to melt together said meltable fibres to dimensionally stabilize the web. The 'thin edges 16 of the web are trimmed off and the main web is sliced longitudinally into separate belts. The bat may receive hot air treatment additionally during the first step. Transverse strength of the belts may be improved by applying to one or both sides of the belts produced by the second step, bats having transversely oriented fibres. These are needled on to the belts and further hot air treatment, or impregnation with synthetic resin, applied.

Filed: 1971-05-04
Abstract: 1346846 Transponder apparatus SOC DE FABRICATION D'INSTRUMENTS DE MESURE 4 May 1971 [5 May 1970] 12995/71 Heading H4L In an apparatus for identifying passing vehicles, an interrogator comprises a microwave transmitter 1 which is frequency modulated by a frequency of 100 KHz and coupled via a duplexer 3 to an aerial 2. The transponder on a vehicle comprises an aerial 9 connected to a short-circuited line or waveguide 10 containing a diode 16 where the received signal is modulated by a frequency of 100 Hz from a source 12. A portion of this modulated signal is demodulated at 13 and via amplifier 14 triggers the transmission at 15 of a binary code formed by frequencies F1, F2 identifying the vehicle, which modulates the received carrier which is reflected by the short circuit and retransmitted to the interrogator station. At the interrogator, the received signal is detected at 4 and frequencies F1, F2 are selected by filters 17, 18, the resulting code being supplied to a store 7 which is interrogated by a central station 8 co-operating with a number of interrogation stations. It is stated that by modulating the wave transmitted by the interrogator with a frequency which is at least equal to one thousand times the modulation frequency of the reflected wave, loss of signal due to the formation of standing waves is avoided.

Title: Improvements in or relating to locks
IPC: E05B29/00
Filed: 1945-05-24
Abstract: 597,247. Lock mechanism. BIALKOWSKI, L. S. May 24, 1945, No. 12996. [Class 44] A lock mechanism comprises members such as balls c movable radially by insertion of a suitably profiled key and imparting movement to longitudinally movable members such as rings b which are to be moved to predetermined positions in order to release the lock. As shown, an outer casing n open at one end and with a closure and external flange at the other end, is fixed to a door &c. by screws s. A cylindrical sleeve p fixed in a bore of casing n by set-screws o has a longitudinal slot g and a number of suitably spaced circumferential slots h (four shown). Within sleeve p is rotatably mounted a sleeve a open at one and with a closure and external flange at the other, the flange serving to retain the sleeve in place by abutment against the end of sleeve p. The end closures of sleeves a, n have registering keyhole r. Slidably housed within sleeve a are a number of annular members b (four shown) with radial projections e slidably guided in the slots f, g, these members, being urged to the left by spring d and retained in sleeve a by an abutment member l fixed in the end of the sleeve. Normally, projections e are out of register with the circumferential slots h, so that sleeve a is held against rotation. The members b have recesses housing pairs of balls c, each pair being held in contact along the axial line by the inclined walls of the recesses. The balls engage in shallow radial grooves in the plane faces of the members b. The insertion of the key k, Fig. 4, moves the balls outwardly and causes axial movement of the members b against the action of the spring d, the movement of each of the members being the sum of the moves of all the preceding members (counting from the end of the lock opposite the end at which the key is inserted), plus its own axial movement caused by the radial movement of the associated balls. The axial movement of the members b brings the projections e into register with the circumferential slots h, allowing the sleeve a to be turned by the key to release the lock. In modified constructions, rollers or levers c<2>, Fig. 7A, pivotally mounted in sliding blocks b<2> so as to be engaged and partially rotated by the key k<2> are used in place of the balls. Two sets of circumferential slots h may be provided, one on each side of the longitudinal slot g, each set requiring a separate key, or slots h<3>, h<4>, h<5>, Fig. 10, leading into short longitudinal slots g<3>, g<4>, g<5> and to further circumferential slots may be provided so that the successive use of two keys is required.

Abstract: 356,223. Screwing die-heads. JACKSON, L. MELLERSH-, 28, Southampton Buildings, London.-(Jones & Lamson Machine Co. ; Springfield, Vermont, U.S.A.) April 2, 1930, No. 13038/31. [Divided on 356,185 under which a Specification was laid open to inspection under Sect. 91 of the Acts, April 4, 1930.] [Class 83 (iii).] Chasers.-In a screw-cutting die-head chasers are movable longitudinally in the holders and are secured in an adjusted position therein by means of transverse serrations on the chasers and on plungers mounted in the holders. The holders 14 are slidable in radial dove-tailed grooves in the head 10 by means of cams 15 and have dove-tailed recesses for receiving similar projections 17 on the chasers 20. The rear ends of the dove-tails 17 are provided with transverse ratchet serrations 24 for engagement with similar teeth on plungers 26 located in housings in the holders 14 and pressed against the chasers by springs 28. Plugs 30 are secured in the holders and carry conically-ended heads 35 at the ends of shanks 34 which pass through slots 38 in the plungers 26. By unscrewing the plugs 30 the heads 35 are drawn into the apertures 38, thereby withdrawing the plungers and allowing the chasers to be removed for grinding or adjustment. Annular shoulders 32 on the plugs 30 fit loosely in apertures in the plungers 26 to allow the latter to adjust themselves on the racks 24 but prevent disengagement. In regrinding the chasers an amount equal to the distance between the serrations in the racks is removed so that by advancing them one tooth the chasers may be reinserted with their cutting edges at the same points. In a modified method of adjustment the plungers 46, Fig. 4, are eccentrically mounted in rotatable housings 50 provided with index notches 62 for co-operation with spring plungers 60 so as to enable the chasers to be adjusted by rotation of the housings. Plugs 53, secured by spring rings 56, engage slots 55 in the sides of the plungers 46 to prevent rotation of the plungers with the housings during adjustment, but a slight amount of rotation is permitted to allow the serrations on the plungers to accommodate themselves to those on the chasers. Specification 356,228 is referred to.
