Abstract: 682,473. Stapling fibres. IMPERIAL CHEMICAL INDUSTRIES, Ltd. July 9, 1951 [July 10, 1950]. No. 17191/50. Class 120(iii) Continuous artificial filaments 4 are cut into short lengths (e.g. to form staple fibres or brush stock) by holding them in contact with the projections on a moving support 1, Fig. 1 and pressing the edge of at least one knife blade against a part of the filaments bridging the gap 2 between adjacent projections, the radius of the edge of the blade from its axis of rotation varying along the length of the blade so that when it is rotated in synchronism with the movements of the support 1 to cut through the filaments the point of contact between the blade and filaments moves in the same direction as the filaments. A tow of filaments 4 is held in a circumferential groove 10 in the wheel 1 by resilient fingers 13, Fig. 3, engaging slots 5 in the wheel 1 at, and to either side of, the cutting zone which is bounded by a and b in Fig. 1. The fingers are carried by a wheel 11 rotated by its shaft 12 which is inclined to the axis 3 of the wheel 1. The latter may be lined, wholly or partly, in the groove 10 with rubber or the like. The knife blades 6, 7, Fig. 2, which have sloping edges, are secured to a carrier 8 or formed integrally therewith, the carrier being rotated by its shaft 9 so that the thin end of the blade 6 starts a cutting operation at a as the thick end of the blade 7 is finishing a cut in the position b. The cutting position of the blades moves from a to b during the cutting operation. The carrier 8 may support, a single blade curled through more than 360 degrees, and the gaps 2 may be wider at the bottom than the top in order to clear the blade. The blades may also be arranged so as not to cut in every gap 2.

Title: Teleprinter control device
IPC: H04L12/12
Filed: 1963-05-06
Abstract: 970,606. Telegraphy. CREED & CO. Ltd. May 6, 1963 [May 4, 1962], No. 17777/63. Drawings to Specification. Heading H4P. A local control unit for a teleprinter is connected to the exchange, from which it receives its current, by a line, and includes a bi-stable circuit which on being switched in response to a signal from the exchange enables means for transmitting address signals. In the idle condition a low current flows in the line, which is increased when the teleprinter calls the exchange on depression of the Start switch. The exchange answers by interrupting the line current for a short period and then sending a low currentthis constitutes a " proceed to dial " signal and causes a transistor bi-stable unit to switch, resulting in the lighting of a " Proceed " lamp and the energization of a relay which connects in the line the dialling contacts. If the called subscriber is available the exchange reverses the line current and the local unit responds to this by lighting a " Connect " lamp, starting the teleprinter motor, and by connection of the printer selector magnets to the line, whereupon transmission takes place. If the called subscriber is not available, the exchange supplies a Busy signal comprising a reversal of current followed by reversion to idle current. On operation of a Stop switch at the teleprinter the line is broken, this being answered by reversal to low current by the exchange. Calling of the control unit by the exchange for receipt of a message comprises reversing the line current, thereby starting the printer motor. The printer may be disconnected from the line for the preparation of perforated tape, the control unit monitoring the line for incoming messages. Break-in.-When an incoming calling signal is detected a buzzer sounds, and the printer is connected to the line and disconnected from the tape perforator either by the operator or automatically.

Abstract: 548,795. Photographic reproduction of drawings. KODAK, Ltd. (Eastman Kodak Co.). Dec. 24, 1940, No. 18117. [Class 98 (ii)] [Also in Group XL] Designs such as engineering drawings, made by means of a fluorescent substance such as calcium tungstate or zinc silicate on a support opaque to visible light, are reproduced by placing in contact therewith a support carrying a photographic sensitive layer, and exciting the fluorescent substance by radiation passed either through the support of the design or through the photographic material, so that an image of the design is produced by the fluorescent light on the sensitive layer. The design may be made on a sheet of metal or wood as with a pencil made from a mixture of the fluorescent substance with carnauba wax and beeswax; or with an ink or paint containing the fluorescent substance and applied with a brush or spray ; or by scribing the surface and filling the lines with fluorescent material. Or the sheet may be coated uniformly with fluorescent material dispersed in a lacquer binder such as a mixture of butyl acetate, denatured ethyl alcohol, cellulose nitrate, dibutyl phthalate, and triacetin, and the design drawn thereon using a non-fluorescent substance which absorbs the fluorescent light from the coating and yields a reversed image on reproduction. The light-sensitive layer also may be coated on a metal sheet, and may be a gelatino-silver halide emulsion, or a coating of silver halide without gelatin. Preferably X-rays are used as the exciting radiation ; any overall fog produced in the light-sensitive layer thereby may be removed by a reducer. The layer may be developed directly or by reversal. Metals which may be used as supports for the design or sensitive layer are aluminium, lead (which may be coated as with aluminium), brass, copper, iron, stainless steel, nickel, silver, tin, and zinc ; and any deleterious effect of the support on an emulsion coated thereon may be avoided by interposing a non- fluorescent substratum such as a layer of white enamel.
