Title: Improvements in or relating to cigarette feeding arrangements
IPC: B65B19/24
Filed: 1963-10-23
Abstract: 1,043,267. Feeding cigarettes. A. SCHMERMUND. Oct. 14, 1964 [Oct. 23, 1963], No. 41801/63. Heading B8A. A block of cigarettes drops from hopper 12 into distributer 14 and is then pushed to position 13 by pusher 11 carried by slides 22 which move along rods 23 carried by frame 24 and operated by lever 28 influenced by a cam. Frame 24 also carries the guide 15 and is pivoted at 25 and the pivotal movement is caused by lever 33 operated through followers 37 and 38 by cams 41 and 42 (not shown). Operation.-As the cams rotate, slides 22 move forward along rods 23 so that pusher 11 moves horizontally to push the block of cigarettes through the now stationary guide 15 to position 13. When pusher 11 reaches the end of its forward movement lever 33 operates to cause frame 24 to pivot about 25. Thus both pusher 11 and guide 15 move downwards. The pusher 11 then moves backwards along rod 23 operated by lever 28 being in its lowered position and when it reaches the end of its backward movement frame 24 is caused to pivot again so that both pusher 11 and guide 15 are raised to the original position as shown to complete the cycle of movement. Second embodiment, Fig. 3 (not shown).- Two pushers 111 and 211 are shown which are caused to move along a rod 123 by lever 173 operated through lever 170 by crank 160 operated by disc 158. Likewise frame 124 is pivoted at 125 and is caused to pivot therearound by lever 168 operated via shaft 157 by cams 137, 138. In this way frame 124 and pushers 111 and 211 operate as before. In addition, the cigarette guides 153 and 253 are carried by member 115 which is carried by sleeves 162 on rods 161 and is caused to move forward as the cigarettes move forward to assist in guiding the cigarettes, being operated via lever 182 from cams 174, 175. Since pushers 111 and 211, and guides 153, 253 are all carried by the pivoting frame 124 they all perform a cyclic movement.

Title: Improvements relating to compressor control mechanism
IPC: F04D27/02
Filed: 1961-11-24
Abstract: 1,005,663. Axial-flow compressors. GARRETT CORPORATION. Nov. 24, 1961 [Nov. 25, 1960], No. 42202/61. Heading F1C. [Also in Division G3] Control mechanism for a compressor comprises a vent valve which is actuated in accordance with the speed of the compressor such that the vent is open over a certain speed range but is closed at a predetermined speed. The control mechanism comprises a housing fed with air tapped from the compressor through a pipe 34 which passes through a filter and orifice member 66 to a chamber 65. The air flows through a nozzle 68 and passes to exhaust through an outlet 75. The flow through the nozzle is controlled by a valve member 77 slidable in a shaft 81 which rotates at a speed proportional to the compressor. The shaft carries weights 95 on spring arms 91, 93, the arm 93 being connected to a sleeve 84 axially slidable in the shaft. Movement of the sleeve is restricted by a pin 84 movable in a slot 83. When the speed increases above a predetermined value the pin moves in the slot and thus moves the spindle of valve 77 to restrict flow through the nozzle 68. The consequential rise in pressure in chamber 65 moves a piston 55 against a spring loading 61 to move a valve 40 from its seat 38 to a seat 43. This movement of the valve 40 permits flow from pipe 34 to a pipe 24 which leads to an actuating device, such as a diaphragm, of the vent valve to close this valve. When the speed is below the predetermined value the valve 40 is in the position shown and the pipe 24 is connected to atmosphere through outlet 48 to allow the vent valve to be open. The nozzle 68 is axially adjustable by ring 71 and is positioned such that the valve 72 does not seat on the nozzle when moved towards it thus avoiding wear.

Title: Counting apparatus
IPC: H03K21/08
Filed: 1972-09-12
Abstract: 1402118 Counting apparatus TEXAS INSTRUMENTS Ltd 12 Sept 1972 42299/72 Heading G4A An arrangement, e.g. a digital clock, for counting electric pulses comprises a matrix store 12 having a plurality of addresses, each address being able to store a number representing the state of one order of a count and means for selectively incrementing the numbers in the store. As shown the store has ten addresses each able to store a 4-bit binary number. A control circuit 4 selects each address in sequence, transfers the stored number to a register 5 where it may be incremented and then transfers it back to the same position in the store. The arrangement counts clock pulses at 10 kHz; between consecutive pulses all addresses of the store are selected and incremented as required. When the lowest order number is selected the register 5 adds one clock pulse to the count; if this causes the count to exceed the capacity of that order a carry pulse is stored at 10. When other orders are selected the number is incremented by any stored carry pulse from the previous order. In order that a display 2 should show seconds, minutes and hours the capacities of the various order must be respectively 10, 10, 10, 10, 10, 6, 10, 6, 10, 10. The variation is achieved by altering feedback circuits 11 at each step of the control 4 so that the register 5 is reset to zero by the next pulse after counting 9 and 5 respectively. If the clock is to display time of day the two highest orders may be adjusted to count to 12 or 24 instead of 100 hours. The matrix 12 may comprise four ten-stage shift registers operated in parallel or may be a random or sequential access memory. Since the numbers are read out and restored cyclically and continuously the matrix need be designed for temporary storage only.

Abstract: 976,783. Angular displacement transducers. GENERAL PRECISION Inc. Nov. 9, 1962 [Nov. 27, 1961], No. 42493/62. Heading G1N. [Also in Division H1] A transducer for measuring angular displacement utilizing the Hall effect, comprises a cylindrical permanent magnet mounted on a shaft, co-operating with a semi-conductor element, the shapes being such that angular rotation of the permanent magnet produces a linear variation of the Hall voltage output from the semi-conductor element. As shown (Fig. 2), a generally cylindrical permanent magnet rotor 11 with one pole on its inner surface adjacent a shaft 13 on which it is mounted, and the other pole on a spirally shaped outer surface 11c, is supported inside a coaxial housing 15. A semi-conductor crystal 23 is located on the inner wall of the housing, and is supplied with a control circuit to produce a Hall plate voltage in conjunction with the magnetic flux from the rotor 11. Due to the cam shape of the rotor and the corresponding shape of the magnetic field, the Hall voltage from the semi-conductor element 23 varies linearly with angular displacement of the rotor. In another embodiment (Fig. 5), the permanent magnet rotor 43 is a regular cylinder with a wedge shaped outer peripheral surface. The output voltage will vary linearly, or as any other desirec function depending on the manner in which the edge surface of the rotor 43 is varied. In a further embodiment (Fig. 3), the rotor 25 is a regular cylinder diametrically magnetised, and the semi-conductor element 34 is wedge shaped, covering 359 degrees of the inner surface of the housing 29.

[Also in Division F4] In melting polymeric thermoplastic material a heater for melting the material is controlled by the pressure of the material on the heater such that when the pressure exceeds a given value the heater is heated to a temperature sufficient to melt the material in contact therewith and the molten material thereby produced is induced to pass away from the heater as soon as it becomes molten. Fig. 1 shows a portable dispenser formed of a tubular housing 10 and having a heater 11 at its outlet end with a nozzle 12 on the outlet side of the heater. A solid rod 13 of hot melt adhesive is placed in the container and is held in contact with the heater 11 by a spring loaded plunger 14 the application force of which is controlled by trigger 21. A spring loaded switch device 18, Fig. 2, is arranged between the housing 10 and the heater 11 such that electric current only flows to heater 11 when the rod 13 exerts sufficient pressure on the heater 11 to overcome the spring 19 to close contacts 20. As the rod 13 melts due to contact with the heater the melt is forced to flow out of the nozzle 12 by the pressure exerted by plunger 14. The heater 11 may be in the form of a rod element bent back and forth (Fig. 3, not shown) and the housing 10 may be of skeleton form.
