Filed: 1963-01-11
Abstract: 972,895. Feeding sheets. PITNEY-BOWES Inc. Jan. 11; 1963, No. 1408/63. Heading B6B. A mis-feed detecting system comprises a sensing device adapted to sense the presence or absence of a sheet at a predetermined location along the sheet feed path and mis-feed indicating means operable under the control of said sensing device for indicating the detection of a mis-feed whenever the sensing device continuously senses the presence of a sheet at said location throughout a predetermined time interval. Registering sheets.-In apparatus for separating feeding, sorting and stacking cheques such as described in Specification, 855,125, separated cheques are fed by a rotating disc 30 and cooperating rollers 32, to driven belts 38, 42 and rollers 40, 44. The cheques are spaced apart a set distance on reaching the belt 38 by means of a pair of spaced discs 100 mounted on shaft 98 and joined by paddles 102. The disc 30 rotates at faster rate than the discs 100 whereby each cheque in turn is fed up to a paddle 102 by the faster moving disc 100 and then, proceeds at the speed of the paddles, slipping relative to the disc 30. Controlling sheet-feeding mechanism &c.- Photo-electric cells 146, 146a are positioned along the sheet-feeding path to detect the passage of the cheques. A magnetic timing unit operated in response to rotation of the discs 100 is provided to emit two series of timing signals and the photo-electric cells are incorporated in a circuit adapted to produce a misfeed indicating signal whenever the photoelectric cells continuously sense the presence of a cheque at a predetermined location, from the time the first one of the two timing signals occurs until the second one of the two timing signals occurs The output of the magnetic timing unit may be shifted in time or fed through a one-shot multivibrator to adjust the spacing of the first and second timing signals, whereby the sensitivity of the mis-feed detection system can be varied. Hence the system may be adapted to detect a jam, a jam and overlapping cheques, or a jam, overlapping cheques and late arrival of a cheque at predetermined locations.

Abstract: 805,400. Jet-propulsion plant. DE HAVILLAND ENGINE CO. Ltd. Dec. 21, 1954 [Jan. 18, 1954], No. 1513/54. Class 110 (3). [Also in Group XII] An air-breathing jet-propulsion engine suitable for use at high altitudes is provided with means for injecting hydrogen peroxide decomposition products directly into a combustion zone in order to stabilize the flame. In the ram-jet engine shown in Fig. 1, an annular fuel injection ring 14 is located in front of the combustion zone 15; in a rocket motor 16 of the " cold " type, hydrogen peroxide is decomposed catalytically and the decomposition products issue from a nozzle 17 at the rear of the rocket motor and pass through the centre of the fuel injector ring 14. The injector nozzles of the ring 14 are slightly inclined towards the main axis so that sprays of fuel cross the path of hydrogen peroxide decomposition products which are hot enough to ensure effective ignition and combustion of the fuel. Instead of using a rocket of the " cold " type, a " hot type may be used wherein some fuel is injected into the rocket reaction chamber for combustion with some of the hydrogen peroxide decomposition products. Fig. 2 shows an after-burner for a turbo-jet engine; fuel from an injection ring 27 is sprayed on to a gutter-shaped stabilizing ring 30. Hydrogen peroxide decomposition products from a catalyst 32 are fed through pipes 31 to the ring 30. An ignition plug 34 is provided for use at low altitudes where the hydrogen peroxide system need not be used. In a modification, Fig. 3 (not shown), at least one pilot fuel injector is provided adjacent the outlet of one of the pipes 31. In a further modification, Figs. 4 and 5 (not shown), the reaction products from " hot rocket combustion chambers are discharged into the ring 30.

Abstract: 1,092,443. Sawtooth generating circuits. BENRUS WATCH CO. Inc. Jan. 13, 1966 [Feb. 16, 1965], No. 1758/66. Heading H3P. In a triggered sawtooth generator, spurious triggering is prevented by producing a complementary pulse in the intervals of time between triggering pulses and inhibiting triggering until the complementary pulse has persisted simultaneously with an end-of-sweep signal. Fig. 2 shows part of an oscilloscope in which synchronizing pulses 20, derived from the Y- deflection signal, are amplified and shaped at 22, 26 to form a main trigger pulse 28 which is fed via an AND gate 40 to the sweep generator 2. A further gate 46 provides a signal on line 44a which is initiated by the presence of a complementary trigger pulse 36 following the termination of end-of-sweep signal 4 and end-offlyback signal 16. The AND gate 40 can thus only provide a trigger for the sweep generator 2 upon coincidence of a main trigger pulse 28 and a signal on line 44. This ensures that triggering of the sweep circuit 2 is delayed until the leading edge of the next main trigger pulse 28 should signals 4, 16 terminate during the previous main trigger pulse 28.

Abstract: 906,084. Stamping; angular bending; shearing. SCOTT, N. April 19, 1961 [Jan. 19, 1960], No. 1814/60. Class 83 (4). A mounting for attaching interchangeable tools to a machine for cutting and working stiff sheet materials such as metal sheets consists of two substantially identical channel or L-sectioned members 10, 11, Fig. 5, which are mounted, with springs tending to hold them apart, on guide rods 14 by means of their flanges facing in opposite directions so as to limit relative sliding movement between the members, the member 10 being attached to the rods 14 and to the machine and the member 11 being slidable on the rods 14 and carrying a tool 15 which is made to engage the workpiece by depressing the member 11 against the resistance of the springs by means provided on the machine frame. Alternatively, instead of springs being inserted between the members 11, 12 they are interconnected by a screw-nut mechanism for operation in the manner of a Fly press. As shown in Fig. 2, the machine consists of an angle member 2 carrying a frame 7 at the front of which is a plate 8 to which the member 10 is secured by screws 8a. The member 11 is raised or lowered by a pivoted lever arm 25 carrying stirrups 24 in which are engaged rollers 23 fitted at the ends of the member 11. Alternatively, the member 11 may be actuated by rotating eccentrics or by a cam. The tool 15 consists of two parts 15a, 15b, Fig. 3, which provide a V-shaped edge for cutting a slot 27 in a metal sheet 26 as shown in Fig. 1. The metal sheet is supported on a pair of bars or cutters 20 mounted on a member 21 and spaced apart to receive the tool 15 between them. The member 21 is secured by screws 9 on a vice-jaw-like member 3 which slides on rods 4 relative to the member 2 when actuated by a screw mechanism 5, 6. When forming louvres 27a, Fig. 1, by bending, the tool 15 is replaced by a die 28, Fig. 2, which carries on each of its sides an inverted casing 30 in which is slidable a spring- pressed bar for gripping the metal plate when the die is lowered. The jaw 3 carries a tool 34 which is brought into register with the die. For press-brake bending a V-shaped or otherwise formed die is carried by the mounting and cooperates with half-cylindrical members which rest in similarly shaped supports on the jaw 3 so as to rotate about their own axes to accommodate themselves to the shape of the die. The mounting and the complementary tools may be incorporated in any of the machines described in Specifications 541,479, 567,943 and 830,278.
