Title: Anti-locking braking system
IPC: B60T8/50
Filed: 1973-03-08
Abstract: 1417921 Anti-lock braking systems AUTOMOBILES CITROEN 8 March 1973 [9 March 1972] 11349/73 Heading F2F A valve 1 is operable by a wheel lock detecting device to disconnect a conduit 12 connected to a fluid pressure source from a conduit 13 connected to a brake cylinder 2, and connect conduit 13 to an exhaust pipe 14. A branch 14a of exhaust pipe 14 is connected to a distributer 9 contained in conduit 13, and fluid pressure exhausted through pipe 14 acts via branch 14a to move a slide 10 in the distributer 9 and thereby cut off communication between valve 1 and cylinder 2 via a groove 15 in the slide 10; if the valve 1 thereafter is actuated to reconnect conduits 12, 13 pressure is supplied to the brake cylinder 2 via a conduit 13a containing a flow limiter 17 and branched on either side of distributer 9. Thus a rapid rise in pressure leading to immediate relocking of the wheel is avoided and the conduit 13a is used for the passage of fluid pressure during the remainder of the braking operation. In the embodiment of Fig. 1 conduit 12 contains a filter 20 and a branch 12a connects with distributer 9. Release of pressure from cylinder 2 when wheel-lock is sensed takes place mainly via a conduit 13b containing a non-return valve 25: pipe 14a contains a non-return valve 23 which allows exhausting fluid pressure to enter a chamber 16 where it acts directly on slide 10 to move it rightwards. Slide 10 contains channels 10a and as the slide 10 is moved rightwards pipe 13 is closed and channels 10a are disconnected from an exhaust pipe 27 and connected to branch 12a. Thus fluid from the pressure source can enter chamber 16 and maintain the slide 10 in its rightwards position. As shown, conduit 26 contains a restriction 27 to prevent too quick an escape of fluid from chamber 16 when the slide 10 is in its leftwards position, this restriction could also be located in channels 10a. In the embodiment of Fig. 2 the chamber 16 contains a piston 11 dividing it into secondary chambers 16a, 16b. Pressure from branch 14a acts in chamber 16b to move piston 11 to thereby move slide 10.

IPC: B60C25/02
Filed: 1954-04-21
Abstract: 789,723. Tyre-removing tools. DUNLOP RUBBER CO., Ltd. April 6, 1955 [April 21, 1954], No. 11431/54. Class 144 (1). A tyre-removing tool comprises a mild steel bar 2 with a cast hook 1 at one end, secured by an adjustable-length chain 4 to a wheel-engaging anchor hook 3, the end 6 of the cast hook 1 having a short flat inner rim flange-engaging surface 7 and a convex tyre-engaging outer surface to provide a tapering tip to engage between a tyre bead and its adjacent rim flange. As shown, the chain 4 is secured at one end to a shackle 5 bolted to the cast hook 1, and its other end passes through a keyhole slot 9, 10 in the shank of the anchor 3, the enlarged portion 9 of the slot allowing free passage of the chain. The anchor 3 is locked in any desired position along the chain by engaging a desired link of the chain within the slot portion 10 of the slot, Fig. 1, so that the depending link abuts the recessed undersurface 11 of the anchor. Alternatively the keyhole slot may be formed in the hook 1 of the bar 2. In operation, with the anchor 3 hooked to a suitable anchorage on the wheel, the chain 4 is adjusted to permit operation of the bar 2 at a point diametrically opposite the anchorage to insert the hook 1 between the tyre bead and rim flange and prise the bead away from the rim. For detachable rim wheels not providing an anchorage for the hook 3, a pair of pincer-like rim-engaging, spring- loaded, mutually pivoted claws may be provided, the anchor 3 being attached to the free end of one of the claws so that operation of the bar 2 tightens the grip of the claws. Specifications 350,652, [Group II], and 789,724 are referred to.

Abstract: 230,313. Soetman, G., Vorster, B. C. A., Soer, H., Grond, A. J. K., and Elias, C. A., (trading as Syndicaat Soetman, C. S.). March 19, 1924, [Convention date]. Weft inserters not carrying bobbins, cops, and the like, looms with.-In looms wherein a weft inserter or main shuttle hving a through vertical groove inserts a loop of weft into the shed, one thread 16, Fig. 1, of the loop thus lying above the other 15, the selvedge or anchor thread 4 is furnished by a pirn in a receptacle 3 held in a recess in a holder 1 supported on a pin on a stepped block, which is screwed to the pin of the loom temple. The receptacle 3 is held resiliently in the holder by a blade spring 5 or a plate 6, Fig. 4. During the first forward movement of the lay, the thread 16 passes under the spring 5 &c. and is guided by the inclined upper face of the receptacle 3 in an upward direction. The thread is thus caused to slip behind and partly under the receptacle, so that when the lay returns and the main " shuttle " moves back, the thread 16 passes under the receptacle. The lay then beats up again, and the thread 16 is looped around the anchor thread 4 whereby it is secured at the selvedge. The receptacle 3 may have a nose or projection to ensure that the weft thread passes underneath it. The holder may be connected by a strap to the breast beam. Specification 21516/04 is referred to. The invention is also applicable in the case where one weft thread is behind instead of above the other.

Patent GB-238825-A (GB)
Title: Process of manufacture of acetic anhydride and aldehyde
IPC: C07C45/54
Filed: 1925-05-05
Abstract: Halogen compounds of zinc are used as catalysts in the thermal decomposition of ethylidene di-acetate to produce acetaldehyde and acetic anhydride.  In an example, a small amount of an acetic acid solution of zinc chloride is added to ethylidene di-acetate which is then slowly introduced into a flask provided with a column.  On heating, the vapours meet zinc shavings, ribbon &c. in the column whereby most of the escaping halogen is returned to the flask. The vapours pass through a second column in which a mixture of ethylidene di-acetate and acetic anhydride is condensed. Acetaldehyde is condensed from the residual vapours by cooling with ice and salt. The mixture of ethylidene di-acetate and acetic anhydride is fractionated as well as the liquid remaining in the distillation flask, a substance, for example potassium acetate, being added to the latter before distillation to prevent further catalytic decomposition.  Compounds such as acetyl chloride or bromide which form halogen derivatives with zinc may be used in place of the halogen derivatives themselves.
