Title: Improvements in or relating to the manufacture of brushes with an elastic bristle holder
IPC: A46B3/16
Filed: 1950-01-10
Abstract: 682,197. Brushes; bristles fixing; stocks. ROSSELL, G. Jan. 10, 1950, No. 613/50. Class 19. A method of manufacturing brushes having elastic bristle holders wherein doubled bundles of bristles are held in seatings, having at their bases narrow bores leading to the rear face of the bristle holder, by means of a wire which is passed round the middle of each of the bundles and through the bores is characterised in that the fastening is performed by means of individual separate pieces of wire for each individual bundle of bristles, each piece of wire being bent up into a U-shape and receiving a bundle of bristles folded together in the centre, both the halves of the piece of wire being twisted together in the manner of a loop and the end portions of the wire left free, the bristle bundles then being inserted in the seatings by pushing the twisted wires through the seatings and then through the bores until the free ends protrude at the upper face of the bristle holder and then bending the freeends outwardly at right angles. In the brush shown, the holder c provided with seatings a, bores d and a rabbet e is moulded from rubber in a single moulding operation. The bundles of bristles in their twisted wire loops are mechanically pressed into the seatings and the free end portion k of the wires bent outwardly by pressure against a backing plate. To further secure the bristles in their seatings, the tips l of the wire ends k are bent round in the form of hooks and pressed into the elastic material of the holder. A back cover plate g is further provided to ensure retention of the wire ends and this plate is removably secured to the back of the holder by means of the rabbet e. The plate g may be made of iron, wood or other rigid material.

IPC: A41H43/04
Filed: 1969-01-04
Abstract: 1,214,281. Laminated fabrics. G.E. CUSICK. 2 Dec., 1969 [4 Jan., 1969], No. 661/69. Heading B5N. An outer facing fabric is bonded to a backing fabric which is made from a thermoplastic naterial or has a thermoplastic or thermosetting material applied thereto by placing the outer facing fabric on a porous working surface of a hollow container, placing the backing fabric on the outer facing fabric so that the thermoplastic or thermosetting material is in contact with the outer facing fabric, covering the backing fabric and the facing fabric with a flexible, substantially non-porous sheet, developing a vacuum in the container under the porous working surface to apply suction to the non-porous cover sheet so that the backing fabric and facing fabric are pressed together and applying heat to the backing fabric and facing fabric to activate the thermoplastic or thermosetting materials to effect bonding. The flexible cover sheet which may be transparent may be of polyethylene terephthalate, silicone rubber coated glass cloth, silicone rubber foam or P.T.F.E. coated fabric. The outer facing fabric may be a woven, non-woven, knitted, braided or lace fabric made from wool, mohair, alpaca, cotton, silk, acrylic, modacrylic, polyester, viscose rayon, cellulose acetate or triacetate, nylon, spandex, polyethylene, polypropylene or glass fibres. The backing fabric may be a woven, non-woven or knitted fabric of cotton, viscose rayon, wool, silk, hair, acrylic, modacrylic, polyester, cellulose acetate or triacetate, nylon, spandex, polyethylene, polypropylene or glass fibres and may be coated with granules of polyethylene, polyvinyl acetate, polyamides, cellulose acetate, polypropylene, acrylic, polyester or polyurethane materials which may contain plasticizers and which may be applied through screens or from a vibrating container and heated and pressed to ensure good adhesion. Alternatively the backing fabric may be printed with globules of adhesive, e.g. vinyl chloride plastisol, in a discontinuous, intermittently-spaced predetermined pattern. Heating may be effected by conduction, convection or radiation using hot air, dielectric heating or laser beams through the platen. Steam may be applied to the materials before or after pressing. The porous working surface of the container may be of perforated metal, sintered metal, woven metal or metal sheet drilled with holes. Electrical heating means may be placed on top of this surface and covered by a cladding comprising cotton padding and a cloth cover.

Filed: 1941-01-17
Abstract: 574,972. Electron discharge apparatus. HILL, S. Jan. 17, 1941, No. 707. [Class 39 (i)] In an electron discharge device of the velocitymodulation type in which the electron stream after passing through a gap in a resonator is directed back through it by a reflector, the electrodes are so formed and arranged that by the application of suitable potentials the field gradient along the electron path is given a positive or zero value (measured from the resonator towards the reflecting electrode) over at least half the distance between the centre of the gap in the resonator and the zero equipotential surface set up between the resonator and the reflecting electrode, thus improving the efficiency of operation of the device. In the form shown, an electrode 6 is provided between a toroidal resonator 4 and a reflecting electrode 5. The resonator and the electrode 5 may be respectively at 1000 volts positive and 100-200 volts negative with respect to the cathode 2, and the electrode 6 at a potential, preferably negative, intermediate that of the resonator and the electrode 5. The electrode 6 sets up between the resonator and electrode 5 equipotential surfaces which are concave towards the resonator, and the field gradient has a positive value for at least half the distance between the middle of the gap 3 in the resonator and the zero equipotential surface set up between the resonator and reflecting electrode. The wall of the resonator adjacent the reflecting electrode is flat, and the reflecting electrode may be flat, as shown, or concave towards the resonator. The electrode 6 may be cylindrical, or a series of short cylinders or apertured diaphragms may be used. The invention may be applied to devices in which a ribbon-shaped beam is used, as described in Specification 574,512, the electrode 6 comprising a cylinder with an elongated cross-section, a diaphragm with an elongated opening, or a pair of flat strips lying parallel to the major axis of the section of the beam. It may also be applied to devices as described in Specification 577,037 in which the electron stream flows radially through an annular gap in a resonator, in which case the electrode 6 may comprise a pair of rings, one at each side of the beam.

Title: A device for typewriters, calculating machines or like machines
IPC: B41J3/50
Filed: 1961-01-09
Abstract: 954,993. Electric selective signalling systems. OLYMPIA WERKE A.G. Jan. 9,1961 [June 23, 1960], No. 841/61. Heading G4H. A device for providing a coded signal on a number of leads e.g. for a tape punch, from a typewriter or calculating machine keyboard includes a number of selector relay R 1 -R 5 , R 34 , R 35  having parallel, branched energizing circuits 22, 30, 31, 24, 25, 33, 34, 35, 36 in which are arranged a plurality of break contacts in series, the arrangement being such that when a character or function key is depressed one, or at most two, break contacts are opened to de-energize one or more of relays R 1 -R 35  and energize corresponding solenoids 55- 59 of the tape punch. For example key "E" opens contact E, Fig. 3 to de-energize R 1  and close contacts r 1 R 1 , r 2 R 1 , the former operating an impulse relay Imp and the latter completing the energizing circuit of solenoid 55. Key "B" opens contacts B 1 , Fig. 3 and B 2 , Fig. 2 so that relays R 1 , R 4 , R 5  are de-energized and solenoids 55, 58, 59 operated. Relays 34, 35 cause solenoids 57, 58 and 58, 59 to be energized together. De-energizing any of relays R 1 -R 35  completes the operating circuit of relay Imp which supplies current to the punch solenoids 55-59 selected over contacts r 2  Imp and energizes a single revolution clutch 66 of the punch over contacts r 3  Imp. Relays R 1 -R 35  are quick-to-release and slow to operate thereby giving a constant impulsing time for solenoids 55-59. The break contacts are preferably operated directly by a lever arm which is connected to a type-bar drive of the associated key.

Title: Lift groups control comprising a device for the down peak traffic control
Inventor: SCHROEDER JORIS DR ING DIPL
IPC: B66B1/20
Filed: 1988-03-17
Abstract: By means of the group control the average time losses for the passengers resulting from the waiting time at the floors and the return travel time are minimized. Therefore, the number of entering stops causing a minimum of time losses is determined per elevator car on the basis of calculations. The number of entering stops is stored in monitoring or control counters by means of which the allocation of down hall calls is limited to the number stored for each car. The down hall calls are combined by means of a switching circuit to form groups of chronologically inputted or incoming hall calls of a volume corresponding to the number of hall calls respectively stored in the monitoring or control counter. In the case of an increase in the hall calls, the earliest group of hall calls is first increased and the latest group of hall calls last. The increase of numbers in the group occurs by transfer of a hall call from the next later group of hall calls and the latest hall call is allocated to the latest group of hall calls. Thus, groups of hall calls are formed, each of which have the same size until the control counting state or level of the monitoring or control counter is reached. The groups of hall calls are allocated to the different cars such that the average time losses of the passengers become a minimum.

IPC: H04N1/00
Filed: 1981-01-06
Abstract: PURPOSE:To display various information while using a conventional device for the reception side, by transmitting video information added with managing information relating such as the transmission line. CONSTITUTION:When line connection in an exchanger 1 is completed, a line passing a number relating transmitted video information and managing information such as passing time are transmitted from the exchanger 1 to the transmission terminal. The transmission terminal stores the managing information once in a memory 13. In this case, a decoder circuit 18 converts the managing information into a video signal, which is applied to the memory 13. The transmission original is inputted to a transmission mechanism 11. When the mechanism 11 detects the start of the transmission original, a control circuit 16 is operative to read out the video signal from the memory 13. Thus, first, the managing information is transmitted. Succeedingly, the original is transmitted. The managing information is obtained without changing the reception end.

Title: Semiconductor laser element
Inventor: TANAKA TOSHIAKI
IPC: H01S5/042
Filed: 1989-01-06
Abstract: PURPOSE:To obtain a semiconductor laser element, which makes a laser oscillation possible in a current of a low threshold value and has a transverse mode which is controlled stably even at the time of injection of a high current, by a method wherein a layer having a conductivity type different from that of a specified optical waveguide layer is formed on the specified optical waveguide layer on the upper part of an active layer as a current constricting layer. CONSTITUTION:A P-type AlGaInP optical waveguide layer on the upper part of an active layer is made thin at an extent of 0.1 to 0.5mum and an N-type AlGaAs layer is formed on the upper part of the optical waveguide layer and is used as a current constricting layer. At this time, by adjusting the composition of the AlGaAs layer so that the band gap of the current constricting layer becomes larger than that of the active layer, a waveguide structure having little photo absorption and using a gain distribution is formed. By this gain waveguide structure, the lateral reactive current can be reduced. Therefore, a laser oscillation becomes possible in a current of a low threshold value. Moreover, by optimizing the stripe width of the current constricting layer at an extent of 3 to 6mum, the spread of a current to the lateral direction of the active layer can be made small and the stability in a transverse mode can be improved. Therefore, an oscillation in a longitudinal multimode using a gain waveguide can be expected up to a high output in a kink-free state.
