Abstract: 1,167,973. Spray carburetters. BRITISH MOTOR CORP. Ltd. June 18, 1968 [July 6, 1967], No. 31151/67. Heading F1B. In a motor vehicle fuel system, the fuel tank and the float chamber of a constant-suction type carburetter are sealed to preclude uncontrolled evaporative loss of fuel, and the fuel vapour produced from them is trapped in a canister containing a bed of activated granular charcoal which adsorbs the fuel vapour; permanent communication is established between the engine air cleaner and the top of the canister; and a pipe leads from the base of the canister to an outlet in the carburetter body adjacent the choke, this outlet being obturated by the carburetter piston whenever the engine is operating under the smaller power output conditions of any legislatively imposed atmospheric pollution test cycle, but whenever the engine is operating at conditions requiring a greater power output, the outlet becomes uncovered by the piston so that the absorbed fuel becomes entrained by the induced air flow and is discharged into the choke region of the carburetter. Fuel vapour produced in the fuel tank 12 and the float chamber 8 is conveyed by respective pipes 15, 16 to corresponding perforated rings 15A, 16A at the top of the charcoal bed in the canister 14. Whenever the engine is operating at a greater power output than under the conditions of a legislatively imposed atmospheric pollution test cycle, an outlet 19 from a pipe 18 is uncovered by the shank of the carburetter piston 4, whereby air can flow from the engine air cleaner (not shown) to the outlet 19 via a pipe 17, the canister 14 and the pipe 18, thereby entraining the absorbed fuel and discharging it into the region of the choke 6.

Title: Improvements in means for guiding fabrics into stentering and other machines
IPC: D06C3/00
Filed: 1921-11-25
Abstract: 192,836. Durrant, G. Nov. 25, 1921. Feeding webs.-In devices for guiding fabrics into stentering, mangling, or other machines, of the kind in which pairs of rollers engage the selvedges of the fabric and are caused to grip or release the fabric by the action of feeder devices engaged by the selvedges, one roller of each pair is positively driven by a device which allows overrunning of the roller if the speed of the fabric exceeds the driving speed of the rollers, and an improved construction of feeler control is provided. The lower roller 3; Fig. 1, of each pair 3, 36, is driven by a ratchet clutch device which may consist of a ring 6, Fig. 3, secured to the roller 3 and provided with internal ratchet teeth engaged by spring pawls carried by a member 9 fixed to the driven shaft 2. A ballbearing is arranged between the parts 6 and 9. Fig. 4 shows an alterntive driving device consisting of a ratchet faced disc 14 fixed to the roller 3 and loose on the shaft 2 and a co-operating spring-pressed ratchet faced disc 16 slidably keyed on the shaft. The selvedge of the fabric moves normally beneath a pivoted feeler lever 28 which is connected by a link 25 to a pivoted pawl 22 adapted to coact with ratchet teeth 21 on a lever l oscillated by a link k from an oscillating lever h, which is moved in one direction by a cam g on a rotating gear wheel f, and in the other direction by a spring p attached to a lever m having a pin and slot connection o with the lever h. This laver m, by its oscillating movement, reciprocates a cam disc q which rotates with the gear f and engages between a pair of rollers u on a lever t carrying a plate v adapted to engage a roller on a bracket w adjustable on a shaft 30. This shaft is fixed in a pivoted support 31 carrying a shaft 32 on which is mounted an adjustable tappet 34 adapted to coact with the pivoted bracket carrying the upper roller 36. While the selvedge of the fabric is beneath the feeler 28, the pawl 22 is held clear of the teeth 21 on the lever l, which oscillates freely, the cam disc q also reciprocating freely between the rollers u. When the selvedge moves from beneath the feeler 28, the pawl 22 drops into engagement with the teeth 21, and the return movement of the lever and thus of the levers h, m and the disc q, is prevented. The rotation of the disc q then moves the lever t, raising the shaft 30 and depressing the shaft 32 so that the tappet 34 presses the upper roller 36 on to the fabric, and causes the latter to return to its normal position; thus again releasing the lever l. The provision of a series of teeth 21 on the lever l allows for automatic taking up of wear upon the teeth. Specification 19300/12 is referred to.

Abstract: 489,166. Optical inspection apparatus. BENZOL-VERBAND GES. Nov. 18, 1936, Nos. 31639 and 31640. Convention dates, Nov. 18, 1935 and Nov. 28, 1935. [Class 97 (i)] In a device for inspecting interior or inaccessible parts of machinery &c., approximately parallel light rays are projected on to the part to be inspected and inspection is simultaneously effected in the direction of the projected rays, without the projected rays dazzling the observer, owing to the use of screening to prevent light reaching the eye except by reflection from the observed object. In the form shown in Figs. 1 and 3, parallel tubes 1, 11 are joined to a third tube 2. The tube 11 contains the holder of the lamp 9 whose centre is located on the axis of the tube 2 and roughly at the focus of the concave aluminium mirror 10 which is cut from large diameter rod. The beam thus produced is reflected from the mirror 7 (see also Fig. 4), also cut from aluminium rod, and the illuminated object is viewed through an aperture 5 in the centre of this mirror. The collar 8 prevents stray light from entering the viewing opening. Cooling grids 14 are provided. A set of attachments 16, Fig. 5, with mirrors 17 at various angles, may be used for objects offset from the axis of the instrument. Each may have a protective cover 19. In another attachment 20, a lens 21 is provided, set at an angle to the light beam to avoid reflection from its surfaces. Either of these devices may be attached at right-angles to the axis of the main instrument by interposing the elbow shown in Fig. 9, containing either a mirror 22 or a reflecting prism 22<1>, Fig. 11. Either may be removed for cleaning by moving the sliding collar 25. If desired, a telescope or a system of telescopic tubes without lenses, may be attached to the observation end of the instrument with or without the interposition of an elbow of the type shown in Fig. 9.
