Title: Improvements in or relating to carburetters and vapourisers for internal combustion engines
IPC: F02M31/08
Filed: 1923-01-11
Abstract: 213,983. Marples, G. M., and Yorkstone, T. R. Jan. 11, 1923. Spray carburettors; vaporizers, external.-Mixture from a carburettor having an adjustable nozzle outlet and an adjustable choke tube is passed through an exhaust-heated chamber and enters a mixing chamber between a throttle valve and an extra air valve which are variablv inter-connected. Two carburettors may be used to supply different grades of fuel. The casing a forms the mixing chamber b and at its upper end has a throttle valve 5 and at its lower end an air valve 23 connected to the throttle valve, and another independently adjustable valve g. A plug j in the valve closes an opening to which a pipe may be connected for drawing off crankcase fumes. The valves 15, 23 are interconnected as shown in Fig. 5. A slot 18 in an arm 17 on the spindle of the throttle valve carries a block 19 which is connected to an arm on the air valve spindle and is adjustable, through a cable 20, in the slot 18 to vary the relative openings of the valve. The carburettor comprises a nozzle 5, Fig. 2a, with an adjustable needle valve 6 and a screwed choke tube 3 adjustable by inserting through the air inlets 10 a bar to engage holes 11 in the bottom of the choke tube. The mixture from the carburettor passes through a tube k which traverses the mixing chamber b, to a U-tube t enclosed in a chamber q to which exhaust gases enter at r and leave at s. The tube t contains grooved atomizing blocks u provided at their ends with tapped holes to facilitate removal. The mixture enters the mixing chamber b at o betwean the valves 15, 23. Fpr using two grades of fuel a branched piece 20, Fig. 8, fitted with a throttle valve 30 may be bolted to the flange n, Fig. 1a. Each branch has a sleeve 33 adapted to receive the upper end 2a, 2b of the carburettor jet chamber.

Title: Improvements in or relating to telecommunication systems
IPC: H04B3/10
Filed: 1943-01-20
Abstract: 562,990. Repeating systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., COWLEY, P. E. A., and WALLS, E. C. Jan. 20, 1943, No. 1037. [Class 40 (iv)] [Also in Group XL] A filter, the attenuating effect of which varies with temperature, is associated with an amplifier, the gain of which varies with temperature in such a manner as to compensate the filter' variations. In the amplifier shown, the (reverse) feed-back path includes a bridge comprising a resistance R of a copper-nickel alloy having a zero temperature-coefficient and a resistance S of iron: The bridge balances at a temperature higher than any likely to occur in the use of the system and the gain of the amplifier thus increases with temperature throughout the working range. The application described is to the arrangements for filtering a pilot current for controlling the gain of a carrier transmission system in which case the overall loss variation with temperature in the pilot-channel filter and amplifier is designed to be the same as the variation, if any, in the filter carrying only the communication currents.

Abstract: 674,347. Tentering fabrics. AKTIEBOLAGET SVENSKA FLAKTFABRIKEN. Jan. 16, 1950 [Jan. 15, 1949], No. 1079/50. Class 42 (i). The upper arm 6 of a tentering clip, which carries a pivoted clamping jaw 8 provided with feeling arms 17, is pivotally mounted at 9 on the link 5 and is rotatable against the action of a spring 12 to the working position shown in which it is locked by a releasable locking device 23. As shown, spring 12 urges arm 6 clockwise, and the arm is retained in the lower position by engagement of a cross-bar 6c beneath a nut 25 on locking device 23 which is pivoted to the link at 24 and is urged clockwise by a spring 26. The lower arm 7 of the clip is covered by a stainless plate 14 and has recesses 15 to receive feeling arms 17. By adjustment of nut 25, the operative position of arm 6 can be raised or lowered to accommodate fabrics of varying thickness. To release fabric from the clip, the tenter is provided with a controlling device past which the clip moves and which turns device 23 counter-clockwise to release arm 6 which then springs to a vertical position, movement of arm 6 being limited by a stop 27 thereon engaging the link. For reengaging fabric, arm 6 is moved by another controlling device from the vertical to the position shown where it is automatically engaged and retained by device 23. Each tenter chain moves in a vertical plane, lateral displacement of the clips for engaging and disengaging the fabric being made unnecessary by the movement of arm 6.

Title: Improvements in devices for taking up wear in brakes and the like
IPC: B60T7/04
Filed: 1927-01-17
Abstract: 265,179. Ainsworth, H. M., Wilde, A. H., and Soc. Anon. des Anciens Etablissements Hotchkiss et Cie. Jan. 28, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Compensating for wear.-A device for taking up wear automatically in brakes and the like comprises two " free wheel " mechanisms 23, 27. Figs. 1 and 2, acting in the opposite direction one to the other and located, the first between a brake, pedal 7 and a brake rigging lever 11, and the second between the lever 11 and a stop ring 17. The boss 15 of the brake pedal 7 is provided with teeth 25 and is loosely mounted on a sleeve of the lever 11 which is mounted on a spindle 8 of a casting 10 secured on the vehicle. The boss 13 of the lever 11 is provided on one side with teeth 26 which engage with the teeth 25 on the boss 15 of the brake pedal and on the other side with teeth 28 which engage with teeth 29 on the ring 17 which has a limited rotary movement through a pin 21 and a slot 20 in a lug 19 projecting from the ring. The teeth are pressed into engagement by a spring 30 and the position of the brake pedal 7 is maintained by a spring 24 and stop 34. When the pedal 7 is depressed the lever 11 is rotated and the pressure of the spring 30 causes the ring 17 to follow with it until the bottom of the slot 20 contacts with the pin 21. Should the brake be not fully applied due to wear of the parts, the teeth 28 of the lever 11 will slip over the teeth 29 on the ring 17, and on the return stroke of the pedal 7 the teeth 25 of the pedal will slip over the teeth 26 of the lever 11 by a corresponding amount and thus take up the slackness automatically. In a modification, the members 15, 13 and 17 may be concentric bushes, the member 17 having a limited rotary movement on the shaft whilst the inner circumferences of the members 15 and 13 are provided with inclined slots and balls which bear on the outer circumferences of the members 13 and 17 respectively to form " free wheels " acting in opposite directions. The slack may be taken up longitudinally by means of serrated plates 15<b>, 13b, 17<b> and 36 Fig, 6. The plate 15b is connected by a rod 7<b> to the brake pedal and the plate 13<b> bv a rod 2 to the brake and a recess 20b is made in the plate 17b for a stop 21b on the plate 13b. The plates are pressed together by a spring 30<b>. The stop 21b may be replaced by the stem 21<a> working in a slot cut in the cover plate 10<b>, the plates 13<b> and 17<b> being integral in this modification. In a further modification, the teeth between the plates 17b and 36 are spaced to have a lost motion equivalent to the travel of the pin in the slot.
