Abstract: 1348329 Plug and socket fastenings VOLKSWAGENWERK AG 28 Sept 1971 [13 Oct 1970] 45083/71 Heading E2B [Also in Division F1] A releasable connection for a spark plug or ignition device, insertable in a wall of a cylinder 1, comprises a sleeve 7 screw threaded into the recess 6 and provided with a crosssection which cooperates with that of a portion 3 of the plug so that the plug may be inserted into the sleeve, until conical portion 15 engages a corresponding portion of the wall, and then rotated by a spannner acting on a separate portion 4, 5 so that the plug is retained by the sleeve. Sleeve 7 has lugs 9, 10, 11 defining axial recesses 12, 13, 14 and axially projecting lugs 17, 18. The plug has lugs 3 which cooperate with the sleeve to form a bayonet fitting. When the plug is inserted it is rotated relative to the sleeve until the lugs 3 engage those 17, 18 on the sleeve. Subsequent rotation of the plug causes the sleeve to be screwed into the recess thereby clamping the plug. A ring 19 or a pin which engages lugs 17, 18 are provided to prevent the sleeve being unscrewed when the plug is removed. The conical part 15 of the plug may be provided by a screw on member 16.

Abstract: 1437182 Counting vehicles or other flowing Objects INDUSTRY SECRETARY OF STATE FOR 25 Sept 1973 [2 Oct 1972] 45257/72 Heading G4D An apparatus for counting objects moving in an interrupted flow includes a counter which is read and zeroized during each interruption of the flow. As described a pneumatic road tube operates contacts 10 operating a relay 11 to trigger a monostable 13. Output pulses, one per axle of each passing vehicle, are divided by two by a bi-stable 14 and counted in an 8-bit binary counter 15. A relay 17 is operated at the start of a green phase of traffic lights and resets the counter 15 to zero, via a monostable 19, before the first vehicle crosses the road tube (placed after the lights). An A/D converter 16 delivers a voltage proportional to the instantaneous count in counter 15. The counter is interrogated before resetting, e.g. by telemetry over G.P.O. land lines. The road tube may be replaced by optical, electrical or magnetic sensing means and the apparatus may also be used to count objects on a conveyer.

Abstract: 982,512. Variable-slip clutches. GENERAL TIME CORPORATION. Nov. 18, 1963 [Nov. 20 1962], No. 45494/63. Headings F2C, F2D and F2L. [Also in Division D1] A constant speed driving arrangement for a knitting machine (see Division D1) includes an electromagnetically operated variableslip disc clutch, of which one of the discs is formed with a series of radial grooves serving for the passage, under the effect of centrifugal force, of oil to provide a shear film between the faces of the discs and for cooling purposes. In the arrangement shown the driving shaft 24 carrries a rotor in the form of annular pole members 135, 136 separated by a non-magnetic annulus 137, and with an outer annulus 143 to which a ring of friction material 145 is secured. The actuating solenoid 165 is mounted within a U-sectioned magnet 160. The armature disc 150, in which the sharp-edged radial oil slots 171 are provided, is splined to a hub member 151 secured to the driven shaft 26. The clutch casing is half filled with oil which, as the clutch rotates, is drawn through an annular passageway 181 between the magnet 160 and the hub 131 carrying the rotor disc, through a series of holes 182 in the latter, from which it passes to the radial slots 171 in the armature disc 150. The oil is cooled by the passage of air from a fan 185 on the driving shaft 24 over ribs 101, 102 on the exterior of the clutch casing. Clutch control.-The driven shaft 26 has an associated tachometer generator 190 in a control circuit, Fig. 9, connected to two of the supply lines L 2 , L 3  for the main drive motor M, the circuit including a step-down transformer 200, bridge rectifier 210 and filtering capacitor 204. The output from tachometer 190 is converted to an A.C. feedback voltage through a bridge rectifier 230, and a selectable reference voltage is provided from a voltage source 210 regulated by potentiometers 215, 217. The tachometer and reference circuits are connected in parallel to the input terminal 236 of an amplifier stage including transistors 241, 242 in series with the clutch actuating coil 165, so that any unbalance in the circuits due to clutch speed variation results in automatic variation of coil current to restore the clutch to the desired speed. U.S.A. Specification 2,422,568 is referred to.

Abstract: 1,142,084. Character generation system for printer. STANDARD TELEPHONES & CABLES Ltd. 12 Oct., 1967, No. 46534/67. Heading G4H. [Also in Division H4] A character generating system for printing or displaying comprises a store 2 or 3 in which a line of characters are stored in coded form, a register 5 into which the characters are entered in turn, decoding circuits 6-10 giving an output on one of 64 leads to identify the character, a translation matrix 11 in which each of 64 character wires are threaded through an appropriate pattern of cores, and an interrogation unit for applying interrogation pulses to the translation matrix in order to read out part of the character formed therein, which signals are passed to the appropriate channels of character forming means. A line consists of twenty characters and each is coded as six binary bits. The stores 2 and 3 are used alternately. At the output of register 5 the character bits are recorded in two threes and after amplification at 8 and 9 are combined at 10. Each character is to be formed by a raster of dots having 9 columns and 15 rows. The rows are read out in turn by the row counter 17 the value in which is recoded to produce marks successively on one of fifteen leads. Each lead is pulsed twenty times, once for each character in a line. After reading out the top row of dots, the next character is placed in the register 5 and the top row of this pattern is read out in the same way. When all the top rows are read out the first character re-enters register 5 and the second row is read out and so on. The contents of the rows are transmitted over nine leads via gates 19, where two blank spacing bits are added, then via stores 20 and amplifiers 21 to a diode matrix 22. Eleven of the 220 outputs of the matrix are switched to the appropriate eleven write heads of the printing machine by inputs from the character counter 24. The groups of bits representing the rows of the separate characters are applied simultaneously or successively to the diode matrix and the corresponding dots are written on the paper passing over roll 26. There may be provision for the input of facsimile signals to gates 19 from input B. Means may be provided for indicating the width of the character and a corresponding signal passed to step counter 24 so that desired spaces are left between characters as printed. The lines may be justified by suitable control of the spaces between characters.
