Patent GB-2182736-A (GB)
Title: A variable drive assembly
Inventor: STIDWORTHY FREDERICK MICHAEL
IPC: F01L1/352
Filed: 1986-11-06
Abstract: A variable drive assembly comprises a first rotatable member (1) carrying a first coupling element (b) which is rotatable with the first member and engages a second coupling element (a) rotatably mounted on a carrier (5, 6, 7) which is rotatable with a second member (2). Rotation of the second coupling element (a) by the first coupling element (b) is precluded so that rotation of the first coupling element (a) causes rotation of the carrier (5, 6, 7) and the second member (2) rotatable therewith. Adjusting drive means (9) are mounted on the carrier (5, 6, 7) for rotating the second coupling element (a) via gears (c and d) to vary the coupling between the first and second rotatable members.

Title: Object identification system
Inventor: OSWALD JOHN MATTHEW
IPC: G01S17/74
Filed: 1987-03-17
Abstract: A reflector (13) is carried on an object to be identified and is operable to reflect incident electromagnetic radiation. Modulating means (14) connected to the reflector (13) modulate the reflectivity of the reflector continuously in a predetermined manner which uniquely identifies the reflector. A receiver (12) receives radiation reflected by the reflector (13) and includes detector means (15) to decode the reflected radiation to determine the identity of the reflector and hence of the object on which it is carried. The radiation may be optical, and the code may be a binary sequence or sequence of audio codes. <IMAGE>

Title: Method for the estimation of reduced pyridine nucleotides and use of the method for estimation of co-a and antibiotics
Inventor: ATKINSON ANTHONY
IPC: C12Q1/48
Filed: 1989-11-03
Abstract: Method for the estimation of an analyte which can be acylated which includes acylating the analyte with an acylcoenzyme A to liberate Co A, causing the Co A to react with 2-oxoglutarate in the presence of NAD and 2-oxoglutarate dehydrogenase to form NADH, and causing the NADH to reduce a further compound, the amount of reduction being measured. Preferably the acylation is an acetylation and the further compound is a tetrazolium salt which is reduced to a formazan. The method is suitable for the estimation of antibiotics which can be acetylated, e.g. thiamphenicol, chloramphenicol and gentamicin. A preferred tetrazolium salt is 2-(2'-benzothiazolyl)-5-styryl-3-(4'-phthalhydrazidyl)-tetrazolium chloride reduced in the presence of 1-methoxy-phenazinium methosulphate.

Title: Apparatus and method for testing transmission synchronizing devices
Inventor: STREHLER RICHARD
IPC: G01M13/02
Filed: 1990-01-18
Abstract: In contrast to a known device for testing synchronizing devices in which only one rotating transmission gearwheel or the synchronizing cone thereof cooperates with a non-rotating synchronizing ring, in the present testing device a complete synchronizing device 1 comprising two transmission gearwheels 2, 3, two synchronizing rings 8, 9 and a gearshift sleeve 10 with a hub 11 can be tested. One transmission gearwheel 3 is securely connected to a rigid frame 25, and the other transmission gearwheel 2 is connected to the drive by way of a driving shaft 14 and a toothed or V-belt 70. A flywheel (29) is mounted on driving shaft 14. The hub 11 together with the gearshift sleeve 10 is mounted on one end of a coaxial driven shaft 16 which is provided with a flywheel mass (30) at the other end. For testing, the gearshift sleeve 11 is moved to the right to couple the driven shaft 16 and its flywheel to the rotating shaft 16 and its flywheel so that the driven shaft 16 is accelerated to the driving speed. The speed of the driving shaft 14 is measured by a tachogenerator. When the driving shaft 16 and flywheel mass (30) are revolving at the driving speed the gear shift sleeve 11 is moved to the left so that the driven shaft is coupled to the gearwheel 3 or its clutchring which are fixed to the frame 25 and the driving shaft 16 is decelerated to a standstill. This procedure can be repeated. Axial force on the fixed gearwheel 3, is measured by a sensor and the torque occurring in the synchronizing device is measured. …<IMAGE>…

Patent GB-2250148-A (GB)
Title: Conversion between analog and digital signals
Inventor: FRINDLE PAUL
IPC: H03M1/66
Filed: 1990-11-15
Abstract: In a digital-to-analog conversion system, an input digital signal D is separated into first and second signals, one of which is the inverse of the other. A digital random noise signal R is then added to the direct and inverse signals to form combined digital signals R-D, R+D which are converted into analog form by two identical D/A converter devices 20, 22 to provide analog signals R-D+E1, R-D+E2 (E1 and E2 representing the errors introduced in the conversion process), and these are then subtracted by a subtractor 24 to form an analog output 2D-EI+E2. Thus the random noise components are removed from the analog output, and also the errors E1 and E2 tend to cancel each other leading to a reduction in distortion. Moreover, any remaining distortion is randomised and thus harmonic distortion is reduced. When the injected random noise signal has a greater resolution than the converter devices, there is also an overall increase in data resolution. A similar technique may also be applied to analog-to-digital conversion systems. <IMAGE>

Patent GB-2245514-A (GB)
Title: Tube fabrication with reusable mandrel
Inventor: SIEMERS PAUL ALFRED
IPC: C23C4/18
Filed: 1991-04-24
Abstract: A method for forming a multiplicity of ring structures having essentially the same internal diameter is taught. A first step in the process is the provision of a mandrel (10) of relatively high thermal coefficient of expansion and the deposit of a layer of un-reactive oxide (14) on the surface of the mandrel. Following the oxide coating of the mandrel surface, a layer (22) of a matrix metal of relatively low thermal coefficient of expansion is deposited thereon to form a ring structure on the mandrel. The coefficient of thermal expansion of the mandrel metal and that of the matrix metal are sufficiently different that there is a spontaneous separation of the deposited matrix metal ring structure from the mandrel as the mandrel and deposited layer cool to room temperature. Following the cooling, the matrix metal ring structure can be removed from the mandrel and the mandrel is then re-coated and thus rendered suitable for repetition of the process to deposit yet another matrix ring structure thereon. <IMAGE>
