Abstract: 1485041 Sorting sheets CROSFIELD BUSINESS MACHINES Ltd 17 Jan 1975 [23 Jan 1974] 03184/74 Heading B8R Documents such as banknotes are fed from a pile 30, Fig. 1, to a store 32 until a complete batch has entered the store, passing detectors 11a, 11b, 11c, which feed information respectively to a document counter 12, to a decoder 13 for the monetary value of a note, and to a register 31 to store information as to which way a note is facing. Signals from the counter and decoder are fed to a comparator 19 and compared with predetermined reference values, and any error signal passes to a batch sorter 130, while signals from the register pass to a document facer 33. The notes are removed one by one from the store 32 after the complete batch is in the store, and fed to the facer 33, which in response to signals from the register 31 reverses notes which are the wrong way round, and thence to the batch sorter. If there is an error signal in excess of a predetermined error tolerance the notes are fed to a stacker 17, otherwise they are fed to a sheet sorter 15, which directs each note to the requisite one of a plurality of stackers 24 in accordance with signals from detectors 20, 21, which sense the general condition and authenticity of each note. The store 32 comprises a rotating drum 50, Fig. 2, having a plurality of radial pockets 51, each to receive one note between a wall 49 and a retaining spring 52, while at the input station a vacuum brake 80 slows the movement of a note towards a stop 57, the members 80, 57 projecting between two parts of the wall 49 of the next pocket. At the input station, notes are fed into the store by a drum 53 and belt 54 co-acting with a stripper 90. At the output station P1, notes are extracted from the store by a vacuum belt 156 and passed to a vacuum drum 98 from which they are released when they reach a stopplate 99, being urged by nudging fingers 96 against a vacuum pad 74, Fig. 5, of the facer 33. In another form of store, Fig. 3, notes are fed by a vacuum drum 60 to a drum 62, and passed round the latter in overlapping formation, being held against the drum 62 by a belt 61. At the output station 8, the notes are extracted from the store by a drum 65 and a guide plate 66, pressed against the drum 65 by rollers 67, 69, and passed to a vacuum drum 68. In another form of store, Fig. 4, notes are stored and advanced in overlapping formation between belts 40, 41, and extracted by a vacuum pad 44, a stripper 45 and a vacuum feed wheel 43. Each note leaving the store 32 is presented to the vacuum pad 74, Fig. 5, of the facer 33, with one end resting against respective vacuum drums 76, 76, which are respectively actuated by energization of the vacuum supply according to whether or not a reversing signal is received from the register 31, so that the note is fed by either vacuum drums 76, 79 or 77, 78 to a position F and thence by the drum 79 to the batch sorter.

Filed: 1930-01-30
Abstract: 348,065. Coin-freed amusement apparatus. PINDER, P., 25, Oakington Manor Drive, Wembley, Middlesex. Jan. 30, 1930, No. 3217. [Class 27.] In a coin-freed amusement apparatus of the kind in which a percentage of the coins inserted are retained, the others being returned in varying quantitites according to an indicated sequence, an indicator drum 4 is provided with an integral toothed wheel 18, the teeth of which vary in height or are divided into segments of unequal numbers so as to impart a variable movement to a pointer 23 showing on a scale 24 the number of coins to be returned. As shown the teeth of the wheel 18 are of varying height. The pointer 23 is actuated through gear wheels 20, 21 by a lever 19 engaging the teeth on the wheel 18. The latter is rotated by a spring catch 32 on a coinholder 25, rotated after the insertion of a coin by a handle 33, depressing an arm 14b of a lever 14 pivoted at 14a. A spring-controlled lever 13 on the weighted arm 14c of the lever 14 is then raised and after the stroke of the handle 33 has been completed falls and rotates a ratchet wheel 12 integral with the drum. The coin falls from the holder 25 down the shoot 9 and by an arm 11, on a pivoted lever 8 which has a roller 10 engaging with cams 5, 6, on the drum, is either retained in the shoot 9 or deflected to a shoot 9a leading to a cashbox. When the roller 10 rides on the drum the arm 11 is rotated so that the coin if retained in the shoot 9 falls on to the drum. When sufficient coins have been inserted to rotate the drum so that one of the slots 7 therein comes underneath the shoot 9, these coins are returned to the player through a shoot 40. The movements of the pointer 23 may be predetermined by inspecting the colour on a rim 4a on the drum shown through an opening and comparing with a chart giving the results for a complete revolution of the wheel 18. A complete stroke of the handle 33 is ensured by a ratchet mechanism 37, 38. The movement of the drum is retarded by an oil dashpot 42 having its ram connected to the lever 14 by a rod 43. Coin action, mechanical-connection.-A coin inserted in a shoot 28 falls into a recess 26 in a pivoted coinholder 25. On rotating the handle 33 the holder is rotated through a crank 35 and rod 36, and the coin, engaging a bridge 31 on a locking member 30, lifts the latter so that a pin 29 on the holder engages its underside.

Title: Improvements in or relating to fuel injection equipment for internal combustion engines
IPC: F02M59/00
Filed: 1943-03-02
Abstract: 566,693. Injector systems ; valves and valve gear. AMERY, M. [Representative of AMERY, G.], and AMERY HOLDINGS, Ltd. March 2, 1943, No. 3411. [Classes 7 (iii) and 7 (vi)] In a fuel-injection system for an internalcombustion engine and including a distributer for fuel under pressure, partially balanced lift valves control fuel delivery to the conduits to which the fuel under pressure is to be distributed. Pistons 113, Fig. 2, of a threecylinder cam-actuated pump draw fuel through inlet passages 118, 117 and deliver it at injection pressure past lift valves 120 to an outlet pipe 12 communicating with each of the injectors, the pressure of the fuel in the injector acting on a piston therein to maintain the fuel admission in the closed position, for example, as described in Specifications 443,124, 468,372, [Group XXVIII], 501,588, 536,294, 546,598 or 566,692. The pipe 12, Fig. 1, also supplies fuel to the inlet pipe 31 of a distributer adapted successively to release the pressure on the pistons in the injectors to permit the fuel pressure to open the admission valves and inject fuel into the working cylinders. An internally-toothed wheel 105 on the cam-shaft 150 of the pump drives the main shaft 50 of the distributer and through spur gearing 49, 48 the shaft 50 rotates a cam wheel 137 supporting adjustable cam rollers 143 adapted to engage tappets 158 which lift valves 151 and permit pressure fuel to flow in turn from the inlet pipe 31 through a passage 164 to the injector pipes 24 ... 27, the pressure thus transmitted to the injectors causing the pistons therein to close the fuel admission valves and end the injection period. Each valve 151 comprises a stem portion of larger diameter than the port 153 closed by the valve which is formed with a reduced neck adjacent the port and an enlarged head 154 seating on the port. The passage 164 opens on to the neck of the valve and as the valve stem is wider than the port, the fuel pressure keeps the valve seated. When the tappet 158 moves away from the valve, the pressure above the valve closes it and then falls away as fuel leaks down an axial passage 156 in the valve, the passage being closed by the tappet 158 while it holds the valve open. To vary the period of the lift of the valve, a cam ring 139 in the cam 137 is angularly adjustable by a spiral gear 146 moved upwardly in a screwed sleeve 145 by a rod 47 operatively connected to the accelerator pedal 65 through a bell-crank lever 61, 63 which also varies the fulcrum 76 of a lever 75 determining the pressure at which a fuel pressure relief valve opens. At starting, the accelerator pedal 65, through the arm 63, engages a plunger 92 open to the pressure in a pipe 94 leading from the fuel pipe 31. As pressure builds up the plunger rocks the bell-crank lever 61, 63, moving the cam 137 into its operative position. A control rod 98 on the starter is adapted to stop the engine by putting the pipe 94 into communication with a drain pipe 95. Specification 556,140 also is referred to.

Abstract: 1,171,484. Digital transmission systems. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 24 Jan., 1967 [27 Jan., 1966], No. 3545/67. Heading H4P. In an error-correcting system each received code word is compared with at least some of the code words of the code. If any comparison shows a Hamming interval #(d-1)/2 (for odd values of d) or #(d-2)/2 (for even values of d), where d is the minimum Hamming interval between code words in the code, the code word received is presumed to be that code word then being compared. On reception of a code word a shift register word generator produces a series of code words with which the received word is compared. A magnetic core threshold unit receives the comparator output, which represents the Hamming interval between the words compared. If any comparison gives an interval within the defined levels the word from the generator is read to the receiver output. If no such interval is found a repeitition is requested. The generator may be divided into two or more sections. For example, when using telegraphic signals the generator will provide only those code words corresponding to upper case symbols in response to code words following a received Figure Shift code word. Alternatively, to speed the comparison the sections may be generated simultaneously so that a received word is compared with two or more words at a time.
