Filed: 1930-05-23
Abstract: 354,880. Induction pipes. AVERNS, R. D., Field View, Skipton Avenue, Fartown, Huddersfield, and WHATMOUGH, W. A., 3, Norman Court, Station Road, New Barnet, Hertfordshire. May 23, 1930, No. 15978. [Classes 7 (ii), 7 (iii), and 7 (vi).] To reduce pulsation of the charge in the induction manifold of a multicylinder engine, the bore of a pipe 1 decreases from a branch leading to a remote pair of cylinders up to a point A adjacent branches 2, 7, leading to another cylinder and the carburetter. The pipe 1 is rectangular in cross section and the taper is produced by inclining the roof 6 at between 2‹ and 10‹. A flat bottom 11 causes any deposited fuel to be revaporized. A hot spot is produced by an exhaust pipe in a gap 10 adjacent the connections 2, 7 which are arranged to deflect the greater part of the charge into the passage 1. The period of vibration of the manifold is the same as, or a harmonic of the period of pulsation of the charge therein at normal engine speed ; plungers in extensions 4 of the passage, moved simultaneously with the throttle, or by a speed governor, effect this at other speeds.
Patent GB-380053-A (GB)
Title: Improvements in or relating to the manufacture of transparent foils, films, wrappingmaterials and the like from regenerated cellulose
IPC: B29D7/00
Filed: 1931-06-02
Abstract: <PICT:0380053/IV/1> <PICT:0380053/IV/2> Foils, films, wrapping material, and similar sheet materials are obtained from viscose, cuprammonium cellulose, and other cellulose solutions in a continuous process wherein the solution is poured from a slot on to a roller rotating in a coagulating liquid, and the film is passed through successive treatment and washing baths, washing water from a tank following a treating bath being fed back to a washing tank preceding the treatment bath so as to prolong the action of the treating agent on the material.  A series of tanks are provided for each treatment and baffles, weirs, or troughs may be provided to ensure adequate mixing of the liquid in the tanks.  The liquid in a series of treating tanks may be caused to flow in counter-current to the film by arranging them in cascade fashion and providing weirs, baffles or troughs through or over which liquid discharges from one tank to the preceding tank. The incoming liquid may be received by a pipe which directs it to the bottom of the tank, or a baffle placed across the tank at the middle may cause the current of liquid to pass from the top to the bottom, beneath the baffle, and up again to the overflow. As shown in the drawings, tanks A, B are filled with coagulating liquid which flows in countercurrent to the film which passes over rollers I, C.  A baffle D placed across the middle of tank A and leaving a small clearance at the bottom of the tank ensures adequate mixing of the liquid.  The level of liquid in tank A is maintained by the weir E over which liquid is discharged into tank B.  The level of liquid in tank B is maintained by a trough F provided with weirs G which are at a little lower level than the lip of the trough.  In the event of an abnormal flow of liquid, the level in tank B rises to the lip of trough F and the whole length of the trough acts as a weir. The liquid passes from the trough to a strainer box H which in addition to the normal outlet pipe has an overflow lip which further aids in the maintenance of a constant level.  The treatments which may be carried out on the film include desulphurizing with sodium sulphite, bleaching with hypochlorite, dyeing, and plasticizing with glycerine, ethylene glycol, or other polyhydric alcohol.  Treatment with plasticizer is preferably carried out at raised temperature so as to reduce the time required for the subsequent drying operation. During the bleaching process, the hypochlorite treatment may be followed by treatment with hydrochloric acid, the acid being washed out with ammonia, or sodium or ammonium carbonate solution.

Title: Improved means for reversing internal combustion engines
IPC: F01L13/00
Filed: 1919-06-26
Abstract: 150,854. Petters, Ltd., and Brooks, H. June 26, 1919. Reversing.-The invention relates to engines of the kind in which fuel is injected into the cylinder by a pump at or near the end of the compression stroke, and in which for reversing, the fuel pump is first put out of action to cause the engine to slow down and then an increased stroke is given to the pump to supply a larger charge, thus giving a premature impulse. According to the invention the fuel pump continues to be operated as in normal running, but for slowing down the engine means is provided for rendering the stroke of the pump ineffective. In the construction shown, the pump plunger 2 is operated by a rocking lever 5 actuated by an eccentric rod 6 and having at the part engaging the pump plunger 2 a laterally adjustable distance piece 3 formed with two diameters and normally held by a spring 4 in such a position; that the smaller diameter strikes the pump plunger. The injection of fuel is stopped by opening the suction valve of the pump by a plunger 8 which is lifted by a lever 9 when one arm of a forked reversing-lever 14 is pressed against a rotating cam 12 by means of a handle 19. When the engine has slowed down sufficiently, an inertia governor 26 displaces a cam spindle 23, thereby returning the lever 9 by means of a rod to allow the suction valve of the pump to regain its normal position and rocking a laterally movable lever 27, which displaces the distance piece 3 to bring its larger diameter opposite the pump plunger. Reversal results from the earlier explosion obtained by the increased charge. The invention may be applied to multicylinder engines having the device described in Specification 121,511, [Class 7 (iii), Internal-oombustion engines, Carburetting-apparatus &c. for], whereby fuel delivered from the pump corresponding to one cylinder can be diverted to one of the other cylinders.

Title: Improvements in or relating to Work Supports for Boot or Shoe Machines.
IPC: A43D71/02
Filed: 1917-11-06
Abstract: 120,420. British United Shoe Machinery Co., (United Shoe Machinery Co.). Nov. 6,1917. Work-supports.-In a jack for a nailing or other machine for use in the manufacture of boots and shoes, the upper end of the jack spindle is slotted to receive a pivoted member 8 of the last pin holder, the lower end of the member being serrated for locking engagement, after angular adjustment, with a device mounted in the spindle. The shank 16 of the last pin 13, which is formed with a shoulder 15 to support the cone of the last, passes through an axial bore in a ball-shaped bearing 23 and its lower spherical end rests on a concavo-convex member 19 movable in a lower spherical bearing of a socket 18. A spring plunger 28 engaging an annular grooved portion 30 of the shank 16 normally holds the last pin tilted outwards, to facilitate the removal of the shoe. The plunger 28 is held in place by a threaded sleeve 27, while the bearing 23 is held in place by a threaded cap 26. In use, the last pin is tipped universally in its holder about the centre of the bearing 23 to present the work properly to the machine, and this movement causes the member 19 to adjust its position to the spherical end of the last pin in the socket 18. When pressure is exerted longitudinally of the last pin, as during the driving of the nails, the member 19 acts as a wedge and automatically locks the pin against lateral movement. Specification 18512/98, [Class 17, Boots &c.], is referred to.
