Filed: 1919-11-11
Abstract: 158,970. Denne, M. T. Nov. 11, 1919. Trimming.-Rotary knives or cutters, particularly adapted for use with inseam-trimming machines, are corrugated before being ground so that a sinuous cutting edge is produced, the different parts of which, in 'the case of a disc, are situated at different distances from the axis of rotation thereof and, in the case of a cylindrical knife, are located in different planes of rotation. The knife blank may be corrugated by being cramped in a holder, or the corrugations may be permanently formed therein during manufacture, the cutting edge being produced by an inclined grinding surface. In the form shown in Fig. 2, a disc 17 is cramped between a conical holder 13, secured to a shaft 16, and a disc 18, alternately situated projections 20, 14, carried respectively by the parts 13, 18, serving to corrugate the disc when the parts are forced together by a nut 19. When ground upon an inclined grinding wheel 12 a sinuous cutting edge is formed, the depth of the undulations being shown by the lines c, d. The application to a cylindrical cutter is shown in Fig. 4 where a hoop 27 is loosely mounted on a carrier 22 secured to a shaft 23. Screwed on the lower part of the carrier is a dished piece 26 the inclined edge of which is adapted to force out sliding studs 25, carried by the part 22, when the member 26 is screwed inwards, thus forcing the band 27 into corrugations. The cutting edge is produced by a grinding wheel 28, the depth of the undulations produced being indicated by the lines e, f.

Title: Joining polyvinyl chloride sheets
IPC: B29C65/48
Filed: 1946-09-17
Abstract: 624,631. Seaming tape. GREENWICH LEATHERCLOTH CO., Ltd., and CZECZOWITZKA, R. H. Sept. 17, 1946, Nos. 27898/46 and 7217/47. [Class 42 (i)] Sheets consisting of, or containing, or coated with, a polymer or copolymer of vinyl chloride are joined by interposing between two such sheets a seaming tape having a continuous surface of a composition containing a low molecular weight polymer or copolymer of vinyl chloride, the composition being compatible with and having a lower softening point than that of the sheets to be joined, and applying pressure and such heat as will raise the seaming tape composition to a temperature above its softening point and as will not raise the sheets to a temperature above their softening points. The necessary heat and pressure may be applied by passing the sheets through heated rollers, or by passing a heated roller over the two sheets, and it is advantageous to remove the heat at once by means of a cool roller or rollers. The seaming tape may consist of a film of said composition, or of a tape or fabric, or other material coated with the same composition and the tapes are preferably made self-adhesive to assist in locating them in the desired position. It is preferred to use a seaming tape composition having a softening point some 30 to 40‹ C. lower than that of the sheets to be joined. The composition preferably contains a plasticiser, and a polymer or copolymer of vinyl chloride of lower molecular weight than the one present in the sheets to be joined. In examples : (1) an interlayer material comprising a polyvinyl chlorideacetate copolymer (M. Wt. 22,000) is coated on both sides with polyvinyl chloride-acetate copolymer (Mt. Wt. 16,000), polymethyl methacrylate, and tricresyl phosphate mixture dissolved in a benzene-acetone mixture and used as a seaming tape to join two pieces of the original sheeting ; (2) an interlayer formed by impregnating light cambric cotton fabrics with a composition containing polyvinyl chlorideacetate copolymer (M. Wt. 10,000), polymethyl methacrylate and dioctyl phthalate is made self-adhesive by applying a coumarone resin, dioctyl phthalate composition and then used as a seaming tape to join pieces of sheeting made from the same copolymer as the sheeting of the first example.

Title: Mobile cordless switchboard
IPC: H04M3/60
Filed: 1962-07-20
Abstract: 987,475. Semi-automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. July 20, 1962 [July 27, 1961], No. 28064/62. Heading H4K. In a mobile cordless switchboard suitable for use on aircraft incoming lines terminate in rotary switch modules 26-30 which are controlled by markings applied by keys in a common control circuit 32 to make connection with an allotted link such as 42. The lines are 4- wire and those shown include a carrier terminal 38, a normal subscriber's station B, an operator's station C and a radio station D. An additional 2-wire line connects to recording equipment R. On the occurrence of a call, a line lamp lights and the operator actuates a corresponding line select key, e.g. K1-K4, and a key associated with an idle link, whereupon the switch of the calling line steps into engagement with that link. Operation of more than one switch at a time is precluded in the control circuit 32. The operator connects her station C to the same link in a similar way, learns the caller's requirements, and then actuates the line key, e.g. 45, of the wanted line and the link key to connect that line to the link. Means are provided for switching over the transmit and receive channels of the called line to ensure proper 2-way transmission. The operator may release the connection to her station, the switch 28 being driven home. When the call is finished all the lines connected to the link may be released by actuation of one only of the line keys and a common release key, the corresponding switches going home. The recording line may be connected up at the request of the subscribers, and may be released individually. Conference calls are set up over links 43 which terminate in a conference circuit 33 provided with amplifiers, these links being accessible over later positions of the switches. In order to maintain balanced bridges, the lines participating in a conference are inserted in successive positions of the corresponding switches under the control of a sequence switch in the conference circuit. All the lines appear as calling lines and thus there is no switching over of the transmit and receive channels. The lines may be released individually, and means are provided for indicating the participants in the conference call.

Filed: 1960-08-12
Abstract: Organosilicon polymers are made by reacting a polymerisable organic compound containing at least one aliphatic double or triple bond with an organo-polysiloxane containing at least one H atom bonded to Si and composed of RxHzSiO 4-(x+z)/2 units, in which R is a hydrocarbon radical, x is 0, 1, 2 or 3, z is 0, 1 or 2 and the sum x+z is not more than 3, in the presence of a catalyst system comprising (A) a compound of a metal of Group VIII (of Mendel<e>aef's Periodic System), or of a metal of subgroups A of Group III to VII or of a metal of Group IIIb, which compound is soluble in or wetted by a solvent which is an aliphatic or aromatic hydrocarbon or ether, and (B) a metal of Group VIIa, VIII or Ib, or a compound thereof which under the reaction conditions is reduced to the metal. If desired, the reaction can be effected in a solvent. Preferably the monomer, siloxane and component (A) are first mixed together in an inert solvent and the whole is then mixed with a solution of (B), the reaction being allowed to proceed at room or elevated (i.e. up to 200 DEG C.) temperature. Monomers specified are:  ethylene, propylene, butadiene, styrene, acetylenes, vinyl-acetate and -chloride, vinyl butylether, acrylic and methacrylic acids and esters, acrylo- and methacrylonitriles, and propiolic acid. The siloxanes may contain as additional units, R3SiO0-5, R2SiO, RSiO1.5 and SiO2.  Catalysts disclosed are: (A) carbonyls of Fe and Co.; Mn(OOC.CH3)3; ReCl3, Mo3Cl6, MoCl5, VOCl3, VCl4; TlOC2H5, Cr(OC2H5)3, W(OC6H5)4(C2H5), Ti(OmC4 H9)4, Mn(OC2H5)2, Re(OC2H5)3, Fe(OC2H5)3, Co(OC2H5)2, Ni(OC2H5)2; Cr(OC2H5).Cl2; aceto-acetic ester chelate of Co; and the acetyl-acetonates of Co, Ni, Fe and Mn; (B): OsO4, H2OsCl6, H2IrCl6, H2PtCl6, H3RRCl6, H2PdCl6, H2MnCl6 and HAuCl4.

Title: Method and apparatus for actuating an electric circuit
IPC: H04B5/00
Filed: 1973-06-13
Abstract: 1428685 Anti-theft alarms T F THOMPSON 13 June 1973 28099/73 Heading G4N [Also in Divisions H3-H5] A tuned circuit attached to an article to be identified or protected from theft is subjected to an intermittent electric field, and its resulting ringing detected only after the field has been given time to decay fully. The electric field may be electrostatic, applied to a protected enclosure by plates 10, 12, Fig. 1, or electromagnetic applied by coils (100, 102, Fig. 6, not shown), or radio applied by an aerial (140, Fig. 8, not shown). The circuits which produce the intermittent field and the receiver 58 which detects the ringing are controlled by squared waves from clippers such that the receiver is actuated only after collapse of the field is complete, leaving the latter part (T4, Fig. 2, not shown) of the decaying ringing oscillation to be detected. In addition, the electrostatic arrangement has its plates 10, 12 shorted out by valve 40 to assist field collapse. The radio system (Fig. 14, not shown) uses transistor oscillator and receiver circuits, the receiver output being blocked by a gate (280, Fig. 15, not shown) while the oscillator is transmitting. The tuned circuit (Figs. 3, 4, not shown) consists of a metal loop (66) between paper sheets (62, 64) and an insulated overlapping segment (68) to form the capacitor. A fusible link (72) enables the circuit to be disabled by application of a strong A.C. field, when a purchased article is to be removed from a shop. Polyiron particles (78) increase the inductance. Three tuned circuits may be used (Fig. 10, not shown) and a receiver with three tuned stages (174, 176, 178, Fig. 9, not shown) employed for improved identification. Two differently tuned circuits (Fig. 11, not shown) enable different frequencies for transmitter and receiver to be used, one tuned circuit causing the other to resonate. A tuned circuit may have its frequency raised or lowered by destroying a fused link in one of two appropriate connections (Figs. 12, 13, not shown).
