Title: Improvement in and relating to the delivery of cigarettes from cigarette-making machines
IPC: A24C5/34
Filed: 1942-06-16
Abstract: 559,548. Testing physical qualities. AMERICAN MACHINE & FOUNDRY CO. June 16, 1942, No. 8242. Convention date, July 16, 1941. [Class 37] [Also in Groups VI and XL] A continuous-rod machine includes an ejecting device normally inoperative but movable transversely of the line of cigarettes issuing from the cutting mechanism of the machine to displace one or more cigarettes transversely, and mechanism for rendering the device inoperative in timed relation to the travel of cigarettes to cause it to displace a selected cigarette or cigarettes from the line of cigarettes. As shown, cigarettes L cut from a rod R are pushed through a guide 46 and normally fall on to a delivery belt 47 ; if faulty, they are deflected into a shoot 82 by the ejecting device 15. The rod R, prior to cutting, passes through a detector box D containing a pair of condenser plates 201, Fig. 6, for detecting overfiliing or under-filling or changes from the normal moisture-content of the rod. The plates 201 are connected, together with a variable and standard condenser 202, between a tuned coil 212 and respective opposite ends of the centretapped coil 206 of an oscillator valve 207 generating, say, 500,000-cycle oscillations, whereby equal and opposite currents are produced at the ends of the coil 206 and no voltage is impressed on the coil 212. In the event of a change of capacity between the plates 201, the resulting voltage across the coil 212 is amplified by a valve 213 and fed through a high-frequency transformer 215 to an electron-ray indicator valve 216 and a gas-filled output valve 217, the plate circuit of which includes the electromagnet 225 and contact 226. In setting up the device, the circuits are tuned to the desired frequency and the condenser 202 is adjusted for zero output of the valve 213, as measured by the valve 216, with a standard cigarette between the plates 201. The amount of permissible variation is adjustable up or down by varying the amplification of the valve 213 by means of a rheostat 230 and the bias on the grid of the valve 217. Specification 558,491 is referred to.

Title: Insecticidal and fungicidal compositions
Filed: 1940-05-08
Abstract: 541,048. Formaldehyde-aryldithiocarbamate condensation products. AINLEY, A. D., DAVIES, W. H., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. May 8, 1940, No. 8266. [Class 2 (iii)] [Also in Group VI] Insecticidal and fungicidal compositions are prepared by the incorporation of the re-action product of formaldehyde with an ammonium aryldithiocarbamate of the general formula R.NH.CS.S.NH 4  where R stands for phenyl, nitrophenyl, chlorophenyl, methoxyphenyl, tolyl or naphthyl with (a) an inert pulverulent diluent (b) an insect bate (c) an aqueous diluent together with an adjuvent. In addition sticking or dust binding agents, wetting, spreading or dispersing agents may also be added. Inert powders mentioned include talc, clay, chalk and kieselguhr. Insect bate materials include cereals and cereal husks, cellulosic materials such as paper or sawdust, cotton seed meal, and animal refuse. The bait may be made more attractive by the addition of molasses, amyl acetate and salt. The active ingredient may be prepared either by re-acting the already prepared dithiocarbamate with formaldehyde in aqueous solution, or by reacting an amine of the general formula R.NH 2  with carbon disulphide and ammonia in aqueous solution and then adding the formaldehyde. The products differ in composition not only according to the dithiocarbamate used, but also with the quantity-of formaldehyde used. The products show an increase in toxicity if more than 2 mols. of formaldehyde are used. In examples (1) the inter-action product of ammonium phenyl thiocarbamate and formaldehyde is mixed with talc and then made into a ground bait for poisoning locusts by mixing it with bran and molasses with sufficient water to make it a friable mass (2) the re-action product of carbon disulphide, ammonia, aniline and formaldehyde is mixed with bentonite, kieselguhr and salt. A highly sulphonated oleic acid is added as a dispersing agent to make a fungicidal foliage spray (3) ammonium pchlorophenyldithiocarbamate is reacted with formaldehyde and the product mixed with talc. The mixture is then further treated as in example (1). Tests are given to show the efficiency of the products.

Filed: 1965-02-26
Abstract: 1,025,399. Automatic brake adjusters. SVENSKA A.B. BROMSREGULATOR. Feb. 26, 1965, No. 8335/65. Heading F2E. An automatic slack adjuster for a vehicle brake linkage comprises a lever 1 which pivots about the axis of a brake-operating shaft (not shown), a worm-wheel 2 housed in the lever 1 and driven through a worm 6, and automatic worm driving means being connected through a lost-motion connection to a stationary bracket 21. Manual adjustment of slack is made by rotating the worm by means of a squared end 9 on a spindle 7 and automatic slack adjustment is made by a separate gear train 18, 17, 16, 13. During application of the brake the lever is rotated anticlockwise. A rack 17 on a spring-loaded slide member 15 causes a toothed arcuate segment 18 to move round a cut-out in the stationary bracket 21 until it reaches a stop 20. Further movement of the lever causes the slide 15 to move upwards relative to the lever against the action of a spring 23, a rack 16 on the slide member then rotating a gear 13 which is free to rotate on the spindle 7. When the lever returns to its original position the arcuate segment returns to a stop 19, and the spring returns the slide downwards relative to the lever, rotating the gear 13 which then turns the spindle 7 through a one-way clutch spring 14 to take up excessive slack.

Title: Apparatus for testing plastic materials
IPC: G01N3/40
Filed: 1935-03-21
Abstract: 431,456. Testing physical qualities of materials. BURMAH OIL CO., Ltd., 175, West George Street, Glasgow, and JACKSON, D. H., Britannic House, Finsbury Circus, London. March 21, 1935, No. 8828. [Class 106 (ii)] Apparatus for carrying out hardness and/or bending tests on plastic materials comprises a pendulum member suspended in a frame to contact without pressure against an indenting element, the frame being rotated through an angle to apply the test. The material is moulded on the serrated face 2 of a carrier member 1 within a mould 5 and when set is expelled together with the carrier by rotating a nut 4. For bending tests the specimen is clamped across a hollow in a carrier having a similar screwed shank 3 and nut 4. A pendulum 10 suspended within a frame 11 upon pivot pins 10<a> carries a steel ball 12 and may be loaded with exchangeable weights 13. One side of the frame has a hinged bridge piece 14 slotted to receive the shank of the carrier which is secured by the nut 4 and a washer 17, the latter and the slot being graduated so that any part of the surface of the specimen may be presented to the ball 12. The frame 11 is provided with a hollow hub 18 journalled in a bearing 19 at one side of a casing 20, a graduated disc 22 on the limb moving over a scale 22<a> on the frame. Relative movement between frame 11 and pendulum is transmitted by rack and pinion gear 24, 25, to a pointer 28 provided with a vernier scale. Pipes 36 serve for supplying heating or cooling fluid to the casing which is insulated. In use, the cover 34 of the casing is opened and the specimen inserted when the bridge 14 has been turned uppermost adjustment being made so that the specimen just fails to touch the ball 12. After return of the frame 11 to vertical position the nut 15<a> is adjusted against the influence of the spring 16 until the specimen just touches the ball which point is indicated by a slight movement of pointer 18. The frame 11 is now rotated to bring it to the zero point with the medium line horizontal and the bridge piece undermost when the full weight of the pendulum acts on the specimen. The depth of the indentation may be read off on a scale associated with the disc 22. As the longitudinal axis of pendulum 10 is no longer in line with the medium line of the frame, a correction indicated by the pointer 28 must be made. The bending test is made similarly by substituting the corresponding carrier. In this case it is usually not necessary to rotate the frame 11 through 90‹, and a detachable rack bar is used with a rear gear to give a reduced motion of the disc 22.

Abstract: 1,189,571. Change-speed control. CENTRE DE RECHERCHES DE PONT-A-MOUSSON. 26 Feb., 1968 [31 March, 1967], No. 9136/68. Heading F2D. An electrohydraulic automatic vehicle transmission includes an electrically-operated valve E v  for locking an engaged gear ratio, the valve having two parallel control circuits, one of which includes a manual override switch X, while the other includes a downshift switch Y in series with a switch Z controlled by a cam 10 on the accelerator pedal H. Circuit details.-As shown for a four-speed gear a stepped plunger 6 controls II-III and III-IV shift switches through an hydraulic diaphragm servo V<SP>1</SP> connected by a pipeline 3 to an output driven member P producing a speed-proportional pressure. The valve E v  is mounted in the line 3 and a second smaller servo V<SP>2</SP> in a branch line 9 controls the downshift switch Y. The shift switches are connected by leads 17, 20, 23 to solenoids E, F, G controlling distributers D for the shift actuators Q, R, S. A fuel control T and manual selector valve Sm are also provided. Operation.-As engine speed increases plunger 6 is raised by servo V<SP>1</SP> against a spring 7 to operate the shift switches and solenoids, of which latter F and G are energized for first gear, G for second, F for third, E for fourth, and E and F for reverse. Closing of the manual switch X causes valve E v  to close to cut off servo V<SP>1</SP> from pressure supply member P, thus holding plunger 6 locked to maintain the engaged ratio. At a predetermined speed the pressure in lines 3, 9 operates servo V<SP>2</SP> to close switch Y, which has no effect so long as the accelerator pedal H is depressed sufficiently to maintain switch Z open, but if the pedal is raised to close switch Z the valve E v  closes to hold the engaged ratio. With the pedal raised a reduction of speed causes reduced pressure in lines 3, 9 to open switch Y and valve E v , thus connecting servo V<SP>1</SP> to exhaust and moving plunger 6 to its lowest position, as shown, under which conditions solenoid G is effective to engage second gear.
