Patent GB-2179603-A (GB)
Title: Motorcycle rear wheel suspension
Inventor: PALMER PAUL JOSEPH
IPC: B62K25/04
Filed: 1985-08-22
Abstract: A motorcycle has lateral stiffness obtained by a laterally rigid linkage interconnecting the main frame 12 and the rear wheel sub-frame 18. The linkage comprises a leaf spring 38 having one end securely anchored to the main frame 12 and the other end pivotally connected to the rear wheel sub-frame 18 through a rigid shackle 40. The main-frame 12 is pivotally connected to the sub-frame by a horizontal bearing pintle journalled in two bearings spaced apart laterally of the cycle. These two journal bearings and the shackle pivots permit the main frame 12 and the sub-frame 18 to pivot relative to one another about the horizontal axis of the pintle and this rocking movement is accompanied by flexure of the leaf spring and pivotting of the shackle, but any relative movement about a vertical axis, eg sideways or lateral swinging movement of the rear wheel sub-frame relative to the main-frame, is positively prevented by the lateral rigidity of the leaf spring/shackle linkage. The leaf spring 38 may be replaced by conventional shock absorbers (82, Figure 9A). <IMAGE>

Title: Process for self-hydrogenation
Inventor: RAMOS JOSE GERALDO FURTADO
IPC: C10K1/20
Filed: 1985-11-27
Abstract: A process for the self-hydrogenation of the olefins, present in refinery gases, at levels of 6-15% by volume or higher, whereby, after separating liquid from the refinery gases stream, a portion of said stream which makes up the feed of the ammonia unit, is admixed to saturated cooled recycle gas and compressed under controlled pressure and the mixture feed-recycle gas is hydrogenated in the fixed bed hydrogenation reactor, so as to reduce the olefin levels to less than 0.3% by weight, and at the same time COS is hydrogenated into H2S, a portion of the hydrogenated gas is carried to a zinc oxide reactor in order to remove H2S, the olefin-free and sulphur-free gas is injected in the steam reformer, another portion of the hydrogenated gas from the hydrogenation reactor is returned to a heat exchanger in order to give heat to the feed, said gas is cooled in another exchanger and the hydrogenated gas is injected in the compressor intermediate stage. <IMAGE>

Title: Security seal
Inventor: DE LIMA CASTRO NETTO EDUARDO
IPC: G09F3/03
Filed: 1985-12-13
Abstract: A security seal comprising a capsule and an element 22 to be retained within the capsule, as well as resilient means operable between the capsule and the element to permit insertion but to prevent removal of the element from the capsule. The capsule comprises two distinct inner 21 and outer 20 parts which, when assembled, define a cavity having an inlet aperture for receiving the element 22. The inner part includes a detent 30 which cooperates with a formation or opening 25 in the outer part to maintain the capsule in its assembled condition. In such condition and with the element inserted in the capsule, the element prevents retraction of the detent and thus also separation of the two capsule parts from each other. The inner capsule part may be transparent to permit inspection, through an opening 25 in the outer part of the region where the capsule cooperates with said element so as to permit one visually to check the physical integrity of the internal structure. <IMAGE>

Title: Mineral insulated thermocouple cable
Inventor: HALLIDAY KENNETH DAVID
IPC: G01K7/02
Filed: 1986-11-28
Abstract: A hot junction 8 is formed at any position intermediate of the ends of a mineral insulated thermocouple cable by locally removing the sheath 4 and mineral insulation at a position intermediate of the ends of the cable to expose a limited length of each conductor 2, 3 and by brazing or welding the positive conductor to the negative conductor to form a hot junction. The hot junction 8 and the exposed limited lengths of conductors 2, 3 are embedded in a refractory cement 9 which is cured by the application of heat, and a metal sleeve 10 is applied over the insulated hot junction so that the sleeve overlaps the neighbouring parts of the cable sheath 4. The sleeve 10 is then brazed or otherwise permanently electrically connected to the neighbouring parts of the sheath 4. The method enables the hot junction to be accurately positioned. <IMAGE>

Filed: 1987-06-04
Abstract: A method of deploying a cable or other line (34) in a fluid transportation pipeline (10) whilst in normal operation full of and transporting a fluid (12) under a positive pressure. A collapsible centralising device (62,64) is attached to the leading end of the cable (34) and is then fed in a collapsed state into the pipeline (10) via a first fluid sealing means (30) at the cable entry position (14).

Title: Power steering system and rotary valve
Inventor: RAYNER ALAN
IPC: B62D5/083
Filed: 1990-06-15
Abstract: A power assisted vehicle steering system has a servo motor ram 1, fluid flow from a pump 8 to which is controlled by an open centre rotary valve 4 responsive to a steering input. Flow through the valve 4 is controlled by circumferential displacement of axially extending control edges 201 on the valve rotor 5 relative to axially extending control edges 200 on the rotor housing. When the rotary valve is actuated to increase fluid pressure to one of the ram chambers 2 or 3 the pressurised ram chamber 3 is progressively closed to communicate with a reservoir 9 by way of two partial pressure drops over control edge pairs G and I. The successive partial pressure drops experienced by the fluid flow over the control edges G and I alleviates noise in the valve. On the low pressure side of the pressure drop at control edges G and on the high pressure side of the pressure drop experienced at the control edges I, a housing recess 12 communicates by way of a by-pass 90, 100 and a vehicle speed responsive valve 101 with the reservoir 9. <IMAGE>
