Abstract: 953,792. Feeding tobacco. D. W. MOLINS, J. E. MORRIS, and MOLINS MACHINE CO. Ltd. April 14, 1960 [April 17, 1959], No. 13189/59. Heading A2C. In a continuous rod cigarette making machine an airflow, passed through cut tobacco moving between the hopper and the garniture of the machine, is conditioned to result in desired characteristics of the tobacco (e.g. moisture content). As shown a carded conveyer drum 10 receives cut tobacco in bulk and carries it past a refuser roller 11. A picker roller 13 impels the tobacco across a guide plate into the entrance of a duct 19. Suction means consisting of a perforated cylinder 16 rotating about two fixed members 17, 18, turns the tobacco stream into the duct 19. A perforated conveyer band 26 is provided at the top of duct 19 above which is a suction chamber 22. The band 26 and chamber 22 extend further (perpendicular to the plane of the Figure) than the width of the duct 19 so that air drawn into chamber 22 by a pump 32 flows partly through duct 19 and partly from atmosphere. A pump 23 draws air into a duct 15 through cylinder 16. Louvred plate 36 deflects dust and shorts into a pipe 39 connected to the inlet end of pump 32, and interposed in the pipe is a cyclone dust extractor 40. A dust extractor 37 and dust extracting cyclone 38 are provided at the outlet of pump 32. Air is discharged from a diffuser 47 and is drawn, together with some air from atmosphere, through a perforated plate 25 partly into the duct 19 and partly into duct 15. The airflow up duct 19 deposits the cut tobacco on to the band 26 to form the tobacco filler. Due to the work done on the airflow by the pumping means the air will be heated. Air conditioning means in the form of an electrical heating element 46 and a heat exchanger 41 connected to a refrigerator 42 are provided. The refrigerator 42 and the element 46 are controlled by a thermostat 48 through a relay device 52 to maintain the air passing through the duct at any desired temperature. If it is desired to increase the moisture content of the tobacco, water or any other liquid may be injected into the airflow by a carburetter or wick device. If desired the refrigerator 42 could be replaced by a radiator. Specifications 895,733 and 909,222 are referred to.

IPC: H03K23/82
Filed: 1959-04-20
Abstract: 885,458. Electronic counting-apparatus. PYE Ltd. April 19, 1960 [April 20, 1959], No. 13402/59. Class 106 (1). [Also in Group XL (c)] An electronic counter comprising a plurality of separate cold cathode tubes also includes an additional cold cathode tube which is connected so that it strikes upon switching on the circuit and thereby ensures that all other tubes are non-conducting, and a particular tube is primed to be the first to operate upon receipt of a counting pulse. A bi-stable circuit comprising cold cathode valves V1, V2 has a third valve V3 connected in parallel with V1. The trigger electrode of this valve is taken to a tapping point on a potential divider R5, R6 across the H.T. supply, so that on switching on the trigger potential is sufficient to cause V3 to strike and thus ensure that the initial output is that from R2, giving a " 0 " output. In operation, counting pulses cause V2, V1 to strike alternately to give either a " 1 " or a " 0 " output from R2<SP>1</SP> or R2 respectively, and the circuit can be reset to " 0 " at any time by applying a reset pulse to the trigger of V3. A ring counter may be used in place of a bi-stable circuit.

A driven pinion within the carrier 3 engages a rack formed on all sections 2 connectable together to form the tower, the upper pulley 6 being supported on either a sliding form 11 above the tower top, or the top section of the tower. The cable 5 depending from the pulley 6, passes through a passage in the counterweight 4, to a tensioning drum 7 at the tower base, which drum 7 is provided with a constant torsional moment from a motor through an hydraulic coupling. The passage in the counterweight 4 is formed by tapered jaws 9 movable through rollers 20 within a tapered aperture in the counterweight, under the control of screw-threaded hub 15 reacting between a holder 16 on the counterweight and cap springs 17 below the jaws 9. The hub 15 is apertured permitting the cable 5 to pass therethough. To wove the counterweight along the cable 5, the counterweight is locked to the tower 1, the counterweight is then disconnected from the cable 5 whilst the load carrier is re-positioned. Power is supplied to the hoist machinery by a power cable 10.

Title: Control devices for pest scarers
Inventor: SPINDLER JOHN EDWARD
IPC: A01M29/20
Filed: 1956-05-10
Abstract: 857,022. Pest scarers. BLANCH & CO. Ltd., A. B. Jan. 16, 1957 [May 10, 1956 ; July 13, 1956 ; Aug. 7, 1956], Nos. 13588/59, 13589/59 and 13590/59. Divided out of 857,021. Class 6(2). [Also in Group XXXVIII] Fig. 1 shows a pest scarer in which a generator 5 containing calcium carbide and water produces acetylene gas which passes through tube 6 via a T-piece 7 to a control mechanism 9 and a control device 11. The control mechanism 9 is connected to an ignition chamber 13 and expansion chamber 14 which are supported by a stand 15 on the ground. The control device 11 is provided with spikes 17 which enter the ground so that it is supported independently of the main part of the pest scarer. The pest scarer may be as described in Specification 734,175. The control mechanism 9 comprises a piston or diaphragm upon which the acetylene gas acts so that the diaphragm is displaced to open a valve and allow the gases to pass to chamber 13. The diaphragm also controls an ignition such as a flint sparking device so that when the gas passes to the ignition chamber 13 the diaphragm is spring returned and thus actuates the sparking mechamism to ingite the gases. As shown in Fig. 3 the control device 11 comprises a clockwork mechanism 18 carried by a plate 19 welded to the lid 20 of a casing, the lid closing a pot 21 having a sealing ring 22 of rubber. The lid 20 is sealed tightly by means of the stud and wing nut 23, 24. The clockwork mechanism 18 drives via gearing a pair of plate like cam members 32 and a clock dial member 33 the members 32 may be angularly adjusted. A cam follower 34 controls a gas valve 37 so that during a period determined by the setting of the clock dial gas escapes through port 39 to the atmosphere, instead of to the ignition chamber. In a modification, Fig. 4 (not shown), the cam members control a flap valve via a lever which when open permits the gas to escape to the atmosphere. The gas valve may also act as a pressure release valve to permit discharge of the gases when a predetermined pressure is reached. The valve may be of the ball cup or piston type Figs. 1-6 the third Provisional Specification (not shown).

Abstract: 956,425. Step by step conveyers. DONKA APPARATENFABRIEK N.V. April 9, 1962 [July 3, 1961], No. 13639/62. Heading B8A. [Also in Division G2] A film-processing apparatus may be arranged to carry out either of two separate processes, having certain common stages, by a device comprising slide bars 15 mounted on carrier bars 12, both pairs of bars 12, 15 being movable vertically simultaneously and each slide bar 15 being movable horizontally with respect to its carrier bar 12 so that a support 21 on the slide bar 15 moves progressively round a predetermined closed path having horizontallyspaced vertical portions. Photographic films 42 on suspension elements 41 are conveyed through tanks of various solutions on conveyers 43, 44, and may be lifted over a dividing wall into the next tank by the elements 41 being picked up by supports 20 attached to the carrier bars 12. Each carrier bar 12 is attached at each end to synchronized endless chains 5, 6 to provide the required path. Such a path may be as shown in Fig. 7 from tank 55 to tank 56. Each slide bar 15 is attached at 18 to an endless chain 11 driven so that points 13, 14, 18 all rise and fall synchronously. When the carrier bars 12 reach their highest or lowest positions the drive to chains 5, 6 is switched-off so that the slide bars 15 may move horizontally under the action of chain 11, the effect being to carry a support 21 mounted on the slide bar 15 over a closed path similar to that of chain 11. As shown in Fig. 7, such a path enables films being processed to miss a tank by jumping, e.g. from tank 56 over tank 57A into tank 57B. The horizontal motion of slide bars 15 may be generated by a lever linkage (Fig. 5, not shown), or by a reversible electric motor or pneumatic cylinder, instead of by chain 11. The horizontal motion of supports 21 on the slide bars 15 may be limited by stops 22, 22<SP>1</SP>, one of which may be adjustable, in conjunction with a telescoping end (Fig. 6, not shown), for the slide bar 15.
