Title: Apparatus for sorting and delivering cigarettes supplied by a cigarette-rod forming machine
IPC: A24C5/33
Filed: 1922-03-04
Abstract: 178,807. Universelle Cigarettenmaschinen-Fabrik J. C. M³ller & Co. April 21, 1921, [Convention date]. Cigarette-making machines.-Tipped cigarettes cut from a continuous rod are separated into two lines before delivery to a conveyer band by one or more plungers which displace axially alternate cigarettes while travelling in pockets c in a wide rotary drum d, driven by worm gearing on the drum-shaft e. In the form shown in Fig. 2, every alternate pocket c contains a plunger g fixed to a rod h passing through the drum. A roller o fixed to the rod h bears against the edge of a fixed cam k which is so shaped as to displace the plunger g against the action of the spring l further into the pocket during rotation of the drum and thus push the contained cigarette to the other end of the pocket. The cigarettes are delivered through a guide a and a slide b to the drum. Fig. 5 illustrates a modification in which one plunger only is used. This is slidably mounted in a sleeve o on one arm of a bell-crank lever, the other arm p of which carries a stud q working in a cam groove in a rotating disc s, thereby causing a travel with the drum of the plunger g during operation, and a quick return. The axial movement of the plunger is synchronous with that of the cutting mechanism which severs two cigarettes at a time. A shield fitting close over the pockets prevents the cigarettes from falling out.

Title: Improvements in or relating to thermionic valve amplifiers and circuits therefor
IPC: H03F1/50
Filed: 1933-03-03
Abstract: 415,796. Valve amplifying circuits. WILSON, J. C., and BAIRD TELEVISION, Ltd., 58, Victoria Street, London. March 3, 1933, No. 6565. [Class 40 (v).] In order that an amplifier may be free from amplitudedistortion and phase-distortion throughout the range of frequencies used in television, the decoupling circuits whereby either the plates or the grids of successive valves are decoupled from one another are replaced or supplemented by distortion-correcting circuits. Thus, a point on the anode resistance of each of the screenedgrid valves of an amplifier (Fig. 1, not shown), may be connected to earth through a decoupling circuit (9, not shown) which, in order that it may correct distortion, consists of an inductance and condenser in series. In a modification, several points on the anode resistance may be earthed through condensers of different sizes or through large condensers in series with resistances. Alternatively, the grid-decoupling circuit 17, 18, Fig. 3, may be shunted by the correcting circuit 19. The grid-bias battery 20 may be transferred to the place of the condenser 18 (Fig. 2, not shown). In other modifications, several tapping-points on the anode resistances of the valves may be earthed through condensers or tuned circuits. Specification 381,254 is referred to.

Title: Rotary vane pump
IPC: F04C3/06
Filed: 1966-03-29
Abstract: 1,145,622. Rotary pumps. TRANSFLO Inc. March 29, 1966 [March 29, 1965], No.6737/66. Heading F1F. A rotary vane pump comprises a hemispherical chamber 20, Figs.2, 3 formed by a hemispherical shell 22 and a flat back plate 24 having a central aperture through which extends a shaft 50 driven by an electric motor 40. The shaft 50 terminates in a rotor 52 having a convex hemispherical surface 54 and diametrally projecting pins 56, 57 which engage a semi-cylindrical recess 68 in an impeller 60 having a pair of semi-annular vanes 62, 64 with a dihedral angle therebetween. The vanes sealingly engage on their outer peripheries the inner wall of the shell 22 and on their inner peripheries the convex surface 54 so that with a frusto-conical member 70 adjustably connected to the shell the chamber 20 is divided into four variable volume compartments, two (A), (B) Fig. 5 (not shown) between the rear faces of the vanes and the back plate 24 and two (C), (D), Fig. 6 (not shown) between the front faces of the vanes, the shell 22 and the member 70. To make sure of sealing contact between the vanes and the member 70 the vanes are made of resilient material, e. g., rubber and the angle between the vanes is slightly less than the conical angle of the member 70 so that the vanes 62, 64 are flexed apart. Preferably however, the front faces of the vanes are provided with ramps conforming to the profile of the member 70. The pump is assembled on the end of a sleeve 36 connected to the motor 40 by means of a bail 30 and a knurled-headed screw 46. The member 70 may be adjusted from a position in which its axis is coaxial with the rotor axis when no pumping takes place to any position above or below the rotor axis to vary the amount of fluid pumped. Depending upon the direction of rotation of the rotor and the adjusted position, above or below the rotor axis, of the member 70, the flow of pumped fluid through ports 82, 84 in the shell 22 may be in either direction. The compartments (A), (B) are arranged out of phase by 90 degrees with respect to the compartments (C), (D) so that as a delivery compartment (C) or (D) is increasing in volume the associated delivery compartment (A) or (B) is decreasing in volume to keep pump delivery substantially constant and avoid turbulence. In a modified drive connection between the rotor 52 and impeller 60, instead of the pins 56, 57 and recess 68, the rotor is slotted on its convex surface to receive a projection formed on the impeller. A spring-loaded collar 96 urges the rotor into sealing contact with the vanes 62, 64.

Title: Production of glycol compositions and their use in the treatment of cellulosic materials
IPC: C07C29/80
Filed: 1966-02-16
Abstract: Mixtures of di- and poly-glycols are produced by diluting with water the distillation residue obtained in the production of ethylene glycol from ethylene oxide and water, and removing from the diluted residue the impurities which separate.  The mixture obtained contains mainly di- and triethylene glycol, the impurities removed being polymers which precipitate on addition of water and inorganic salts which separate when the water is subsequently distilled off.  The glycol mixture, which initially has a high pH, may be used, after neutralization and bleaching if desired, to impregnate wood to reduce its shrinkage.ALSO:A mixture of glycols obtained as a distillation residue in the production of ethylene glycol from ethylene oxide and water is purified by diluting with water and removing the impurities which separate, and may then be used to impregnate fine wood to reduce shrinkage and prevent the formation of checks.  The glycol mixture, which has a dark brown colour, may be bleached before use e.g. with hydrogen peroxide and may be used in association with a plastic binding agent, e.g. a phenol-formaldehyde or urea-formaldehyde resin.

Abstract: 1,071,633. Brake indicators; controlling brakes. GIRLING Ltd. March 12, 1964 [Feb. 22, 1963], No. 7169/63. Headings F2E and F2F. [Also in Divisions G1 and H3] Each of three or more valves or transistors, all fed from the same constant current source and all connected via diodes to a switching valve or transistor, is supplied with a signal I representing one of a plurality of physical variables such as the speeds of different axles of the bogey of a railway vehicle, and the switching valve or transistor conducts if the value of one variable departs from that of the remainder by more than a predetermined amount (indicating, e.g., slipping of a wheel during acceleration, or locking during braking). The total current flowing through three transistors T, for example, is set a P by varying the base voltage of a transistor T1, so that if the current through one transistor changes by a certain amount due to a change in its input, I, an opposite change of half that amount occurs in each of the other two transistors T. A sufficient rise in potential of one or more collectors causes the corresponding diode(s) to conduct and switch on the transistor T2 whose output O may operate an alarm circuit or reduce the power supply to a slipping wheel. A change in value of a variable in either direction may be sensed, while a change of all the variables in the same direction produces no output provided that the predetermined difference between them is not exceeded.
