Title: Improved elastomeric products
IPC: C08L23/02
Filed: 1958-11-24
Abstract: Fibre reinforced elastomeric articles are made by applying to a substantially saturated hydrocarbon elastomer, fibres of a highly crystalline, linear, high molecular weight polymer of an alpha-olefin of the formula CH2=CHR where R is an alkyl group, mixed with one or more polymerizable hydrocarbons which contain at least one ethylenic double bond in the molecule and an activator acting with a free radical mechanism and heat-curing the fibre-reinforced elastomer to unite and cross-link the components of the article.  The hydrocarbon elastomer may be natural rubber, polybutadiene, butyl rubber, or a copolymer of ethylene and propylene.  The preferred polymer of an alphaolefin is polypropylene.  The fibres may be in the form of fabrics or cords. The articles are preferably made by applying a solution of all p  the ingredients to a fabric.  The fibres may be peroxidized after spinning.  The monomer used is preferably divinyl benzene in admixture with ethylvinylbenzene.  The exemplified activators are dicumyl peroxide, and tert. butyl perbenzoate.  The mixture to be cross-linked may also contain carbon black, and a plasticizer such as an unsaturated hydrocarbon obtained from acid petroleum sludge.

Title: Device for measuring camber and casters
IPC: G01B5/255
Filed: 1975-09-15
Abstract: 1456970 Measuring caster and camber of vehicle wheels A ROME GmbH 15 Sept 1975 [16 Sept 1974] 37871/75 Heading G1X The camber and caster angles of a vehicle wheel are measured by a device comprising a body 4, a spirit level 14 pivotally mounted thereon about an axis which, in use, is parallel with the plane of the wheel, and a manually rotatable member whose rotation is arranged to pivot the level. A stationary caster scale 26 is carried by the body 4, and a camber scale rotates with the rotatable member. An indicator 22 is rotatable at choice relative to or together with the rotatable member, and extends to the caster scale 26. As described, the rotatable member comprises a knob 20 and threaded spindle 28, a disc 24 carrying the camber scale also being rigidly mounted on the rotatable member. A head 40 co-operates with the screw thread of spindle 28 to pivot a lever 42 about spindle 44, a spring 46 forcing a carrier 16 for the level 14, which is mounted for pivotal movement about the spindle 44, against an adjustment screw 18 carried by the lever 42. A spring washer 32 in a groove 34 of knob 20 frictionally engages the indicator 22 with the disc 24. A peg 8 engages within an aperture in a jig Fig. 3 (not shown), that is secured to the vehicle wheel by clamps, screws, spring clips, or magnets. The camber angle is obtained by turning knob 20, and hence scale disc 24, until the bubble of level 14 is centred. The zero mark 60 then indicates the camber on scale disc 24 (2‹ 30' as shown). The caster angle is obtained by centering the bubble as above for the wheel turned approximately twenty degrees outwards, turning the indicator 22, but not the disc 24 to point to mark 60, and then turning the wheel inwards by twenty degrees. Rotation of the knob 20, and hence disc 24 and indicator 22, until bubble is centred allows the indicator to give the caster angle on scale 26 (+ 6‹ as shown).

Title: Process for the recovery of concentrated sulphuric acid from salt-containing dilute waste acids
IPC: C01B17/90
Filed: 1960-11-03
Abstract: Concentrated sulphuric acid is recovered from dilute waste acids containing more than 0,3% aluminium sulphate and possibly other metal salt impurities by concentrating the waste acids at 140-160% to 55-65% by weight sulphuric acid, ageing the concentrate, with precipitated salts at 120 DEG -150 DEG C. for up to 10 hrs., cooling by evaporation under vacuum at 90 DEG -100 DEG C., ageing again at 50 DEG -100 DEG C. for at least 6 hrs., filtering and further concentrating.  The first concentrate may be filtered before the second ageing step and seed crystals added to the filtrate which is then aged for a further 10-20 hrs.  Alternatively the first concentrate is evaporated under vacuum, aged at 50-100 DEG C. for not more than 2 hrs., filtered, and seed crystals added to the filtrate, which is then aged for a further 10-20 hrs.  The waste acid may be that obtained from the breaking up of titanium-containing ores by concentrated sulphuric acid after hydrolysis of the titanium sulphate solution and filtration of the titanium dioxide hydrate.  The seed crystals may initially be obtained from a portion of the filtrate from the first filtration step by cooling to room temperature to precipitate the salts and redissolving by heating to 100 DEG C. and recrystallizing by cooling to 60 DEG C.  Subsequent seed crystals are obtained from the filter cake of the second filtration step.

Title: Braking systems
IPC: B60T8/30
Filed: 1974-09-02
Abstract: 1485959 Load responsive brakes BLEREAUPEG 2 Sept 1974 [5 Sept 1973] 38336/74 Heading F2F  The braking of a fork lift truck is regulated by means of the pressure of the fluid in the hydraulic jack 1A supporting the load. The brake assembly includes a master cylinder 8A supplying pressure fluid to a wheel cylinder 10A operating shoes 12A in a drum 11A and a valve 7A in the circuit also receives fluid from a pressure multiplier or reducer 4A acted upon by fluid pressure from the jack hydraulic circuit via a valve 2A automatically opened when the brakes are applied, the valve 7A being responsive to the relative pressures from the two sources so that the braking is modulated in response to the load on the fork lift jack. The valve 7A accepts the highest pressure so that the automatic operation can be over-ridden manually. The braking can be arranged to come into action as soon as the vehicle has a movement in a direction opposite to that selected by the driver. It can also be arranged to apply to an inner wheel when the vehicle is cornering so it is initiated as from a predetermined angle of the bend or from a predetermined threshold speed, or it may be combined with electro-dynamic braking.
