Patent GB-2074764-A (GB)
Title: Multiprocessor computer system
IPC: G06F15/16
Filed: 1981-04-08
Abstract: A multiprocessor computer system comprises a plurality of data processors (121, 123) connected to a common data bus (124). In order to effect an arbitration operation should more than one processor require access to the data bus at the same time each processor is provided with an arbitration element (120, 122) which is also connected to the data bus, the data bus being used as an "arbitration bus" when an arbitration operation is being carried out. Each processor has assigned to it a unique priority number which determines its priority in the hierarchy of processors and, when a given processor requests access to the bus, it activates a request line (136, 140) to the relevant arbitration element. The element responds by applying the corresponding priority number to the bus, the system being such that, if more than one priority number is fed to the bus at the same time, the bits of the number actually occurring on the bus are the AND or the OR functions of the corresponding bits of these priority numbers. Each active arbitration unit then (a) compares the number on the bus with its own priority number and (b1) declares itself the winner and activates an acknowledge line (138, 142) if the two correspond, (b2) withdraws its own priority number from the bus if the most significant bits of the two differ, or (b3) returns to step (a) if these two bits are the same but no processor is declared as the winner. Steps (a) and (b) alternate until a winner is declared, the significance of the bits considered in successive operations (b2) and (b3) being reduced by 1 each time. <IMAGE>

Patent GB-2106254-A (GB)
Title: Vehicle wheel alignment testing
Inventor: MILLS DOUGLAS PEARSON
IPC: G01B7/315
Filed: 1982-09-20
Abstract: A vehicle wheel alignment testing apparatus comprises a movable floor plate (10) and a remote display indicator (12). Lateral movement of the floor plate causes arcuate movement of a head (18) mounted at one end of a pivotable arm (14) and this co-operates with a series of pick- up elements (20) to produce an output indication for the display. The pick-up unit (18, 20) avoids the use of mechanical switching elements and functions magnetically or electro- magnetically. The movement of the floor plate (10) is transmitted to the arm (14) by a system of rollers and link members to ensure that the floor plate moves laterally without twisting and that the thickness dimension of the unit is very small, typically about 30 mm. The pick-up unit may include reed switches or an array of coil pairs whose electromagnetic coupling is rendered a maximum or a minimum by the presence of the head (18) e.g. of iron or copper. <IMAGE>

Patent GB-2133738-A (GB)
Title: Improvements in or relating to disc record preparation
Inventor: STRAUSFELD HERMANN
IPC: B29C43/02
Filed: 1983-01-18
Abstract: A disc record press suitable for moulding video discs comprises a pair of opposing mould blocks, (20,21) to which stamper plates (24,25) are affixed, assembled between flat and parallel rams (30,31). The mould block surfaces facing the stamper plates are normally slightly convex and the mould block surfaces facing the rams (26,27) are normally slightly concave such that when the press is retracted, the stamper plate pressing surfaces (28,29) are slightly convex. During disc pressing, the high pressing force causes the mould blocks and stamper plates to elasticably deform to have flat and parallel surfaces. As the press retracts, parting of the stamper plates from a moulded disc takes place gradually from the disc periphery towards its centre with an arcuate motion, thereby substantially avoiding damage to the disc modulations due to differential shrinkage and air influx. <IMAGE>
