Title: Fluid pressure control valves
IPC: B60T8/18
Filed: 1974-05-08
Abstract: 1468821 Proportioning valves; load responsive braking AUTOMOTIVE PRODUCTS Ltd 8 May 1974 [15 May 1973] 23080/73 Heading F2F A vehicle braking system fluid pressure control valve 11 having a body 13 with an inlet 12 connected to a master cylinder and an outlet 14 connected to a rear wheel motor cylinders comprises a movable valve member 39 co-operable with a valve seat 41 to control communication between the inlet 12 and the outlet 14; the valve member 39 is screw-threadedly attached to a plunger 23 having a free end 59 engaged with resilient means (not shown) connected to an axle of the vehicle to apply a load to the plunger 23 which is related to the loading of the vehicle, and the actual load applied to the plunger 23 by the resilient means is determined by the position of an abutment (e.g. 53) the plunger 23 is urged by the resilient means towards the abutment 53 and the abutment 53 is movable with respect to body 13 whereby the operation of the control valve 11 can be modified by suitable positioning of the member. As shown in Fig. 1, the valve seat 41 is formed as part of a plunger 43 and the plunger 43 is urged by a compression spring 45 seating upon a shoulder 47 of plunger 23 into contact with the axial abutment 53 which is provided on a plug 49. The plug 49 is screwed into a bore 15 in the body 13 to an extent which affects the actual load applied to plunger 23 and carries a seal 57. In operation fluid pressure is initially transmitted from inlet 12 via a first chamber 61, a passage 35 in plunger 23, open valve 39, 41, radial slots 40 in valve member 39, and a second chamber 63 reaches a level sufficient to overcome the resilient means the plunger 23 moves away from plug 49 to close valve 39, 41 increased pressure in the first chamber 61 subsequently moves the plunger 23 to open valve 39, 41. In this way the outlet pressure is proportioned relative to the inlet pressure. In the embodiment of Fig. 2 the valve 11 has a plug 67 with an axial bore 69 containing a plunger 76 with a seal 84 abutting plunger 43. The position of the plunger 76 is alterable by means of a grub screw 78 provided with a lock nut 79. A shoulder 82 on plunger 76 proves an abutment for plunger 23. In the modification of Fig. 3 (not shown) the plug (86) is similar to plug 67 but a radial aperture (88) is provided to allow a feeler gauge to be inserted between the grub screw (78) and the plunger (76). A flexible boot (90) prevents ingress of dirt.

Abstract: 775,423. Toggle fasteners. K.A.C., Ltd. Dec. 10, 1953 [Sept. 16, 1952], No. 23269/52. Class 44. A toggle fastening secures two relatively movable parts by means of a toggle lever 24 connected to a primary part 1 by a link 30 and connectible to a recessed secondary part 2 be means of forked side cheeks 25 of the toggle lever which engage fulcrum discs 44 on the part 2, the toggle lever 24 having an extension arm 46 to provide additional purchase in moving the toggle into its locked position. The primary part 1 comprises two spaced L-shaped members 7 carrying pins 67 to align the part with the outwardly turned flanges 15 and 18 of the laminated housing comprising the secondary portion 2. The fulcrum discs 44 comprise the heads of bolts secured to the side walls of the portion 2 and are recessed about the inner portions of their peripheries to engage corresponding flanges 43 on the inner edges of the forks on the toggle lever 24. Pivotally connected between the side cheeks 25 of the toggle lever is the square head 37 of the link 30 the other end of which is pivotally mounted between the L-shaped members 7 of the primary part 1. The link 30 can be varied in length by an axially contained bolt sliding through the head 37 and threaded into the remainder, the head of the bolt being knurled and held by a spring detent 39. The extension arm 46 is pivoted at 27 to the free end of the toggle arm and is limited in rotation by a pin 26 and a projecting portion 47 of the extension lever which, when the toggle is locked, engages the lower edge of a spring-loaded catch plate 51 pivoted in the recess of secondary part 2. The lower edge of the catch plate is bevelled at its end portions so as to ride over and engage the bevelled ends of the toggle lever when this is forced against it. The catch plate 51, toggle arm 24 and lever 46 lie flush with the parts secured when the toggle is locked, and to effect disengagement it is necessary to push the catch plate inwards against spring 59 so that a projecting toe 64 on the plate automatically ejects the extension lever 46 from its stowed position in which a bulbous projection 50 is held by a spring clip 48. Once ejected the extension lever may be swung upwards so that a projecting portion 47 on the lever 46 bears against the arm 66 on which the catch plate is mounted and with a cam action forces the catch plate inwards to a disengaged position so that the toggle may be pulled outwards from its over deadcentre position. Specifications 644,699 and 681,949 are referred to.

Title: Improvements in and relating to golf and the like balls having an outer cover or shell of balata, gutta-percha, rubber or the like and the manufacture thereof
IPC: A63B37/00
Filed: 1932-08-26
Abstract: A process for making golf and other balls having a cover of rubber, gutta-percha, balata or the like moulded to a cover is characterized by diffusing into the cover after it is moulded one or more gaseous, liquid or solid agents essential to low-temperature vulcanisation. In one example a golf ball is moulded with a shell composed of gutta percha, a zinc compound such as zinc oxide, sulphur and a secondary amine such as dibenzylamine.  The moulded ball is then exposed to the vapour of carbon disulphide and afterwards to air and then stored at 38-45 DEG  C. during which partial vulcanization occurs. Alternatively a moulded ball containing 1 per cent sulphur is immersed in an alcoholic solution of zinc stearate and piperidine piperidine-1-carbothionolate containing about 10 per cent of each for one hour and after removal is kept at 40-50 DEG  C. for 24 hours. In another process a moulded ball containing 1 per cent zinc-isopropyl-xanthate (or zinc-diethyldithio-carbamate) and about 5 per cent zinc oxide is embedded in sulphur at 37-42 DEG  C. for 12 days.  In a further alternative moulded balls containing zinc oxide are embedded in a mixture of 95 parts sulphur and 5 parts zinc-diethyldithio-carbamate made into a paste with acetone and heated to 38 DEG  C. for about 72 hours.  Or, a moulded ball containing 5 per cent zinc oxide and 5 per cent sulphur is immersed in a 12 per cent solution of piperidine in alcohol for 20 minutes, then in a 12 per cent solution of carbon disulphide in alcohol for 20 minutes and afterwards heated at 20 DEG  C. for 20 minutes.

Abstract: 1311818 Carbon fibres and fabrics BAYER AG 19 April 1971 [14 March 1970] 23907/71 Heading C1A Carbon fibres are produced by heating a carbonizable fibre material to a temp. of between 150 and 400 C. in the presence of free oxygen in a first zone and subsequently carbonizing the material in a second zone at a temperature of 1000 C. or higher in an atmosphere of inert gas, hydrogen or a mixture thereof, the fibre material being passed between the said zones through a liquid which is inert to the fibre material and substantially free of water, the liquid forming a substantially gas-tight seal through which the fibre enters into the second zone. The preferred carbonizable fibre is polyacrylonitrile. The free oxygen containing material utilized in the first zone may be air and fibre material may be under tension. The liquid seal may be at 0 to 50 C. The liquid used may be a material that is liquid below 100 C. and may be benzene, heavy gasoline of b.p. 123 C. or a eutectic mix of diphenyl and diphenyl ether. An apparatus suitable for performing the process comprises a stock roll 1 (see Fig.) from which a fibre strand is drawn, via rollers 4, by a first pair of tension rollers 3, and a second pair of tension rollers 5 through a furnace 6 into which air is passed. The strand then passes via roller 10 and funnel 18 into trough 15 where it passes via rollers 19 through liquid 17, exiting by dip tube 20 and rod 21 it passes into tubular furnace 12. Here the strand is carbonized in an oxygen free atmosphere and is finally wound up on roll 14.
