Title: Improvements relating to liquid level or depth gauges
IPC: G01F23/18
Filed: 1928-03-20
Abstract: 313,662. Higginson, J. March 20, 1928. Indicators, alarm and signal.-In a liquid-fuel tank for a motor vehicle, from which fuel is drawn by suction, the withdrawal pipe is provided with a bell fitting extending to the bottom of the tank, and a pipe exending from the bell to an alarm or indicator to indicate the fall of the liquid below a predetermined level. A vacuum feed device a, Fig. 1, is connected to a pipe b terminating in a bell f dipping into the liquid. During suction, air is drawn in through pipe p open at the top, and mixes with the fuel, so that on the return flow of fuel down the pipe b this air is entrained and keeps the bell f full of air. The depth of fuel is indicated by a gauge n. A small aperture 4 is provided at the level of the end of the pipe b, so that when the fuel falls to that level, the gauge n reads zero at periods of non-suction, and below zero during periods of suction. In Fig. 2, the bell f is connected by a pipe g to a cylinder h having a piston i adapted to uncover a signal lamp j when suction is exerted on the pipe g due to fall of the level below the end of the pipe b. In a modification, Fig. 3, not shown, the movement of the piston i is utilized to complete the circuit of an electric lamp. In another modification, Fig. 4, not shown, a. whistle is placed in the outer end of the tube g. A pressure gauge n may be provided on the tube g to indicate the level, and a small hole q, Fig. 5, may be provided to admit air to the pipe b during the suction period, this entrained air being carried into the bell f during the return flow. The Provisional Specification describes also a modification in which the supply pipe has a non-return valve to prevent return flow, and a second pipe is provided with an air leak and with a valve which cuts off communication with the supply pipe during suction but not during the return flow. In other modifications, the second pipe may include a Venturi tube, or a small chamber may be connected to the supply pipe, into which air is dra.wn during suction and from which it is delivered into the bell during return flow. Specifications 179,966, 268,565, 279,282 and 284,594 are referred to.

Title: Tape dispenser
IPC: B65H35/00
Filed: 1950-04-11
Abstract: 678,741. Tape-dispensers. FRITZINGER, G. H. April 11, 1950, No. 8880/50. Class 18. To facilitate further withdrawal by projecting a length of pressure sensitive adhesive tape from a tape dispenser after each application, the length of tape between the pressure roller 19 at the exit of the dispenser and the supply roll is increased during the tape severing action whereby at the end of the severing action this excess length of tape is projected from the dispenser. In ore embodiment the actuating mechanism pivots mainly about a pin 41, and its operation is achieved by a finger depressable projection 23 on an arm 24 pivotally connected to a pin 25 mounting the roll of tape and being actuated to move the roll of tape away from the pressure roller 19. In so doing the arm 24 engages a lever 37 pivotally mounted on the pin 41 which lever deflects a second arm 47 carrying a guide roller 51 ensuring alignment of the tape for severing by a knife 39 on the end of the lever 37 and to which roller 51 the tape adheres so that upon release of the projection 23 it delivers the end of the tape through the exit opening in the dispenser. A spring 29 serves to return the mechanism to its normal position. In order to conceal and protect the end of the tape the mechanism may be retained in its operative position by a catch 56 on the projection 23 engaging a lip 57 on the casing of the dispenser. In an alternative arrangement the supply roll of tape may be retained stationary and a roller pivoted on an arm moved across the normal path of the tape so as to increase its length. Upon the return of the roller the excess tape is fed out of the dispenser.

Title: Improvements in or relating to crankshaft knuckle pins
IPC: F16H21/34
Filed: 1940-03-19
Abstract: 539,931. Bearings. UNITED AIRCRAFT CORPORATION. March 19, 1940, No. 8951/41. Convention date, March 21, 1939. Divided out of 539,822. [Class 12 (i)] [Also in Group XXVI] In an engine with one or more link rods pivotally connected with the master rod on the crankshaft, the knuckle or gudgeon pins are rotatable with limited freedom of axial movement relative to both link and master rods. A bearing element, interposed between the two relatively movable members and rotatable relative to one or both of them, has limited axial movement as described in Specification 539,822. The master rod 22, Fig. 1, has a sleeve 27 around the crank pin 12 retained by end plates 52, 54 having extensions interengaging with extensions on the sleeve 27. Pressure lubricant from the hollow crankshaft 16 is conveyed through aperture 72 in the crankpin, annular grooves 74, 76 in the sleeve, and channels 60 in the end plates, 52, 54 to recesses 58 in extensions 56 of the end plates which engage bushings 44, 46 to the gudgeon pin 38. The oil pressure forces the plates against the cheeks of the crankshafts, the plates and rod 22 having engaging flanges 66, 68, while the bushing 27 has limited axial movement between the plates. The bushings 44, 46 may comprise extensions of the pin 38 or separate members pinned at 48, 50 to the pin 38 and have oil passages leading to radial channels 84 in the pin for supplying lubricant to the bushing 42 of link rod 40.

Patent GB-1077254-A (GB)
Title: Process for preparing alkyl benzenes from petrol fractions
IPC: C07C15/02
Filed: 1966-03-01
Abstract: Alkyl benzenes are produced by alkylation, with a C2-16 olefin or C1-16 alkyl chloride in the presence of an acid catalyst or Friedel-Crafts catalyst, of an olefin-free benzene fraction obtained from either petrol formed in a pyrolysis plant or a plant for the catalytic recovery of aromatics from petrol.  It has been found that provided the olefins are removed the benzene fraction need not be pure, typical impurities being cyclohexane and isoparaffins.  The olefin removal is either conventional, e.g. by hydrogenation (in which diolefins and acetylenes are also removed), or may be achieved by a preliminary alkylation stage in which the olefins react with part of the benzene.  In the latter case the diolefins and acetylenes may be removed by moderate hydrogenation prior to the preliminary alkylation.  The main alkylation reaction is preferably carried out continuously using a molar excess of benzene over olefin or alkyl chloride, and, after appropriate fractional distillation of the product, unreacted benzene, polyalkyl benzenes and non - benzene components are recycled, usually after removal of a small cut to avoid undue build-up of nonbenzene components.  In examples the alkylating agents used are ethylene, propylene, tetrapropylene and dodecyl chloride, and the catalysts used are AlCl3, HF or polyphosphoric acid.

Title: Improvements in and relating to air compressors
IPC: F02P5/10
Filed: 1927-04-02
Abstract: 293,133. Pescara, R. P. April 2, 1927. Regulating compression. - A direct acting air compressor comprising a main internal-combustion cylinder in the two ends of which motor pistons work on the two-stroke cycle and are connected with compressor pistons synchronized mechanically, has means in the ignition circuit for varying the ignition according to the working of the compressor. The shaft 12, Fig. 1, driven by the oscillating synchronizing means described in Specification 268,773, carries an insulating distributor 13 on which is a pivoted pawl 14 adapted to contact with a screw 16. The pawl passes through a slotted bar 20 which moves the pawl into contact under centrifugal force and withdraws it under action of a spring 23 carried from a bell crank; tension of the spring may be regulated by screwing the cap 229 down on the crank. The periphery of the distributor carries contacts 24, 25 connected respectively with the screw 16 and the bell crank. The contacts overlap as shown in Fig. 3, and coact with brushes 29, 30 connected through alternative contacts 42, 43, and a third contact 41 with the primary circuit. The contacts are bridged by a brush 40 on a lever actuated by a coiled tube 34 connected with the air storage tank. A spring-pressed ball 48 bearing against a notched sector on the lever causes a rapid movement of the lever. The shaft 12 and contact 25 are earthed. When the distributor comes to rest in the position shown, the spring 23 retracts the pawl 14. and the circuit previously made through brush 29, contact 24, screw 16 and the pawl is broken, producing a spark. This position corresponds with the adjacent position of the pistons. The pistons are driven apart, causing the distributor to move in the direction of the arrow 61 towards the other arm of the angle a. When this position is attained, the brush 29 is in contact with the contact 25 and the separation of the parts 14, 16 by the spring produces no spark. If the distributor over-runs in the direction opposite to the arrow 61, a cam 33 pushes the bar 20 back and breaks the circuit. When the pressure in the tank increases sufficiently, the lever 38 is snapped over and the circuit is now completed through brush 30, replacing brush 29. As shown in Fig. 3, the brush 30 will be in contact with the earthed contact 25 in the terminal positions, and no spark will result. The amplitude of oscillation will diminish until the brush 30 is in contact with contact 24 in the terminal position, when a spark is produced and this occasional sparking continues regularly. Specification 294,967 is referred to.
