Patent GB-1324825-A (GB)
Title: Regulating devices for the flow of fuel in internal combustion engines
IPC: F02D1/12
Filed: 1970-12-30
Abstract: 1324825 Regulating I C engines SOC INDUSTRIELLE GENERALE DE MECHANIQUE APPLIQUEE 30 Dec 1970 [31 Dec 1969] 61856/70 Heading F1B [Also in Division G3] In a control mechanism for a fuel injection pump, centrifugal governor 4a Fig.9 responds to engine speed variations and pivots lever 23a about point 24 to displace a spool 22 controlling leakage at 50 from a large-area side of servopiston 32a whose half-area side is supplied by inlet 40a and accumulator 80 Fig.2 and connects with the fullarea side via orifice 41a. The servopiston thereby follows the spool movements to control the injection pump via rack 33a the movements of which are fed back to lever 23a by a lever 52, which pivots at 53, and a delay unit defined by piston 62 adapted to expel or draw fluid through restricted passage 75 when loaded by spring 68 through rod 65. The levers 23a, 52 return to parallel relation as the mechanism regains equilibrium. With pivot 53 on the same horizontal line as pivot 12a, the fullload engine speed equals the no-load speed, but by displacing the pivot 53 up or down in slot 57 the full-load speed will be respectively less than and greater than the no-load speed. In the practical embodiment of Figs.1 and 2, governor spring 10a is adjustable by axial adjustment of seat 13a by a toothed sector 16a, rotatable between stops (18a, 19a) corresponding to maximum and idling speeds, or by a shaft 48, rotatable by motor 49 or a handwheel. The lever 23a abuts the end of spool 22a and is also connected to the latter by spring 27a. Handle 28a allows manual over-ride control of the spool to move the rack leftwards to its minimum flow setting; as an alternative arrangement, a solenoid valve 102 Fig.7, (not shown) can be deenergized to prevent return flow via port 44a Fig.2 2 from the casing whereby the pressure builds up in servo-chamber 38a to displace piston 32a leftwards. In the idle position, the spool 29a abuts a stop 29a defining the fuel setting at start-up; this stop can alternatively be adjustable by a cam or an electromagnet Figs.5 and 6 (not shown). Plate 36a closing servo-chamber 38a is radially displaceable so that the spool 22a is guided solely by the servopiston.
Patent GB-766633-A (GB)
Abstract: 766,633. Grinding. LUX, H. G. March 14, 1953, No. 7126/53. Class 60 A grinding wheel has apertures in the form of slots, holes or the like, which extend from its working face through the wheel and the rate of rotation of the wheel is such that a persistant view can be obtained through the apertures of a workpiece during operation thereon by the grinding wheel working face. A disc wheel 1, Figs. 1 and 2 has radial slots 2 of different lengths so that at the circumference of any concentric circle approximately the same ratio exists between apertured surface area and working surface area. The side walls of the slots 2 may be inclined relative to the end faces of the wheel and the end faces 3 of the slots 2 may be inclined to the axis of the wheel; this promotes air flow. The wheel may be provided on one face with a plate 4, Fig. 6, having registering slots, the tongues between them being bent like propeller blades to produce an air stream through the slots. In a modification, Fig. 7, the wheel 1b may have three spiral rows of holes 5, the axis of each hole being on a circle concentric with the wheel and tangential to the circumference of the two adjacent holes; the wheel is held in a carrier 6 the face of which is similarly apertured. Two wheels 1 may be mounted on the ends of the shaft 10, Fig. 10, of an electric motor 7 carried by a trunnion 9 held in a bracket 8. A rod-shaped lighting fixture 11, Fig. 11, provided close to the wheel shaft 10 is covered by a conical shade 12 the rim 13 of which extends into a recess 14 in the wheel 1; alternatively the rim 13 may extend into a flange on a plate secured to the face of the wheel. The face of the wheel nearest the operator may have a dull black finish. The wheel may be a cup wheel.

Title: Constructional toys
IPC: A63H33/10
Filed: 1978-09-01
Abstract: A child's constructional toy kit made of resilient plastics material includes a plurality of panel members and a plurality of connecting members. The connecting members are of two kinds, one of which is basically an elongate rod and the other of which is a sphere. Both the rod and the sphere type of connecting members are grooved, and the edges of the panel members have beads joined by a lip of reduced section so that the beads can be slid longitudinally in the grooved elongate or spherical connecting members and be releasably gripped therein. The co-operating parts are so formed that when the members are in engagement with one another the connecting member is constrained to move along the bead of the panel and cannot be released transversely of that edge. <IMAGE>

Title: A Clutch for Conveying Rotary Motion
IPC: F16D17/00
Filed: 1979-03-13
Abstract: A clutch for conveying rotary motion between a first member 11 and a second member 12 comprises a hollow coupling body 10 splined to the member 12 for relative axial motion but not relative rotary motion. In the body 10 is an inner member 14 with an eccentric internal toothed ring in mesh with a gear wheel 17 secured to the member 11. The inner member 14 is located by balls 19 and 20 and a cover 21 held by a spring ring 22, but the inner member 14 is radially or tiltably shiftable in relation to the body 10. When the body 10 is raised (as shown in Figure 4) dogs 18 on the member 11 are freely accommodated in a recess 23 in the body 10, the gear wheel 17 drives the inner member 14 into forcible contact with the body 10, and then the clutch and the members 11 and 12 rotate in unison. When the body 10 is lowered the dogs 18 lock in recesses in the inner member 14 which is thereby caused to rotate with the member 11 relative to the body 10 and the clutch is therefore disengaged. <IMAGE>

Title: Pallet rack joint
IPC: A47B57/40
Filed: 1980-07-29
Abstract: A beam (3) is connected to a stanchion (5) by means of a connecting member (17) at the end of each beam (3) with hooks (20) to engage openings (14) in the stanchion (5). A part (21) of each hook (20) is inclined to vertical and engages an inclined edge (16) of the opening (14) with a wedging action, while a depending portion (22) of each hook (20) has an edge (24) inclined to the vertical in a plane normal to that of edge (16) to engage a lower edge (15) of the opening (14) with a wedging action. This prevents longitudinal and transverse movement of the beam (3) relative to the stanchion (5). A crank locking pin (25) engaging the connecting member (17) and the opening (14) in the stanchion prevents the beam (3) being accidentally detached from the stanchion (5). <IMAGE>

Title: Improvements in or Relating to the Production of Tin
IPC: C25C5/02
Filed: 1980-08-01
Abstract: The invention concerns the extraction of tin from cassiterite and other tin-bearing ores and wastes. In the present process, aqueous or solvent carried reducing agents are used to reduce the insoluble higher valency tin compounds to soluble lower valency stannous salts. The conditions, and choice of reagents are preferably such that a soluble stannous compound of tin is formed, and complete reduction to the metal does not occur. Preferred reducing agents are the divalent vanadium and divalent chromium ions. The metal may be recovered as a powder on a suitable electrochemical cell, such as any of those described in British Patent 1,505,736. The solution which has been depleted of tin may be electrochemically reduced to the active reducing agent before re- contacting a further batch of tin ore.
