Patent GB-2057218-A (GB)
Title: Detecting focussing error
IPC: G11B7/12
Filed: 1980-06-19
Abstract: An in-focus condition of an optical system 1, 2, 3, 4, 5, intended to focus a spot of light onto a surface 6, such as a video disc, is characterised in that light reflected from the surface 6 is caused to impinge upon a surface 11 set at a critical angle with respect to light reflected from the surface when the system is in-focus, whereby when the system is not in-focus reflected light impinges upon the surface 11 as either a convergent or a divergent beam, rather than as a parallel beam, and as a consequence half of the light impinging upon the surface 11 passes through it rather than being reflected by it. This loss of intensity of the light reflected by the surface 11 is detected by a split detector 12A, 12B, and used 13 to provide a signal indicating an out of focus condition. Numerous modifications are described. <IMAGE>

Patent GB-2069723-A (GB)
Title: Fuel pumping apparatus
IPC: F02D41/40
Filed: 1981-01-21
Abstract: A fuel pumping apparatus includes an injection pump to which fuel is supplied through an adjustable throttle 28 (see also Figure 1, not shown) and which includes a fluid pressure operable device 35 for controlling the timing of delivery of fuel by moving a cam ring as usual. In order to accurately control the timing in accordance with the speed and the amount of fuel supplied to the engine a transducer 45A is provided to sense the throttle position and a further transducer to measure the pressure upstream of the throttle. The signals from these transducers together with an engine speed signal are supplied to a circuit 47 which computes or on the basis of stored information, provides a fuel quantity output signal which is supplied to a further circuit 48 together with a speed signal which produces a desired timing output signal. This signal is utilized via an error amplifier 49 operating an adjustable throttle 50 to control the pressure applied to the device 35. Various modifications of the basic system are described with respect to Figures 7 to 12, not shown. To make the output signal ofthe transducer vary linearly with flow, the end of armature wings 46 coacting with pole pieces 47 are modified (eg as in Figure 5, not shown). Governor details are disclosed in Figure 1 (not shown). <IMAGE>
Patent GB-2071236-A (GB)
Title: Overload coupling
IPC: F16D7/06
Filed: 1981-03-10
Abstract: An overload coupling which normally couples together two rotary parts (1, 2) but which releases on excessive torque comprises a series of entrainment bodies (e.g. balls 3) which are urged by springs (4) into matching recesses (8, 9) in the parts (1, 2) to cause those parts to rotate together. Circulation tracks (10, 11) on one or each of the parts connect the recesses of the respective part. When the torque becomes excessive, the entrainment bodies are forced out of the recesses (8, 9), thus breaking the coupling, and relative movement of the parts (1, 2) occurs, with the entrainment bodies rolling on the circulation tracks between successive recesses. Either or both sets of recesses (8, 9) may be specially contoured to give a particular overload characteristic or to allow overload release in either direction of relative rotation (Figures 2 to 4 (not shown)). In further embodiments the balls 3 may be caged and the cage may be connected to a planet carrier of a planetary gear system driven by the parts 1 and 2, one set of recesses may be formed by a plurality of rotary cams, the entrainment bodies may be caged rollers, or one set of recesses may be formed by grooves inclined to the axial direction and the other set by radial projections (Figures 6 to 10 (not shown)). <IMAGE>

Title: Acid leach process for treating magnetic and non-magnetic nickel-copper mattes
Inventor: KERFOOT DEREK GEORGE EAGLAND
IPC: C22B23/00
Filed: 1982-10-18
Abstract: Magnetic and non-magnetic nickel- copper mattes are treated by an acid pressure leach in which the initial phase is leached out under oxidizing conditions until up to 70% of nickel values are extracted, at which time the leach is continued under non-oxidizing conditions. Copper values are converted from a basic copper sulphate formed during the oxidizing phase to a less acid-soluble form as digenite such that a resulting nickel-rich leach solution has reduced copper values permitting purification of the said leach solution by an atmospheric leach in which non- magnetic as well as magnetic nickel- copper mattes can be added for precipitation of dissolved copper and iron values. A further acid pressure leach is effected under oxidising conditions on the Cu-containing residue, copper recovered from this leach solution and the latter recycled to the first stage pressure leach to maintain the pH therein at 1.8 to 5.0. <IMAGE>

Title: Improvements in or relating to electroluminescent devices
Inventor: WAITE MICHAEL STUART
IPC: H05B33/22
Filed: 1982-11-30
Abstract: A thin non-planar layer 22 of non- conducting substance is interposed between the phosphor layer 14 and (preferably) a transparent electrode 18 of a direct current electroluminescent device. The non-planar layer is generally from 100 to 500 millimicrometre in thickness, and may be, for example silicon dioxide or germanium dioxide. The non-planar layer may have either an undulating cross section (Figure 1), or it may be in the form of closely spaced dots (Figure 2). In either case, the non-planar layer is applied by a vacuum evaporation process. This arrangement reduces the power expenditure in the forming process. <IMAGE>
