Title: Fixed word storage arrangement with interpolation facilities
IPC: G06F17/17
Filed: 1973-12-19
Abstract: 1444819 Interpolator SIEMENS AG 19 Dec 1973 [23 Jan 1973 25 May 1973] 58719/73 Heading G4A [Also in Division F1] The value of a function Z of one or more independent variables is obtained for values of the variable(s) by interpolation using values of Z for certain possible values of the variable(s) stored in a read only memory. The arrangement is for controlling an internal combustion engine, see Division F1. Signals x 0  and y 0  representing engine speed and throttle setting are fed to A-D converters 29 and 30. The most significant bits MSB(x 0 ), MSB(y 0 ) of the resulting digital words x 0 , y 0  are used together to address a read only memory 24 storing the values of a function Z = F (x, y), e.g. ignition timing data for the engine, for those values of x and y given by all the combinations of the most significant bits of x and y. A counter 28 has a number of bit positions equal to the number of the remaining least significant bits of x 0  and y 0 , LSB (x 0 ), LSB (y 0 ) and is incremented through a complete cycle for each interpolation. For each value of the counter contents the least significant bits of x 0  and y 0  are compared with respective groups of bits in the counter. If the least significant bits are greater than their associated group of counter bits the corresponding most significant bits are incremented by one and used to address the memory 24. If the least signaificant bits are less than or equal to their associated group of counter bits the corresponding most significant bits are used unchanged to address the memory 24. The values of Z read out of store 24 are accumulated in register 21, the final contents of the register being divided by the number of values through which the counter contents have passed, e.g. by a shift operation, to give the final interpolated value of Z for the input values of x 0  and y 0 . The final value of Z is fed to a D-A converter 21 whose output is used to control the engine. In a modification two read only memories are provided storing ignition timing and fuel injection duration, the two memories being used alternately to provide data to control the ignition timing and fuel injection duration. The arrangement may also be used for functions of three (or more) variables.

Patent GB-630966-A (GB)
Abstract: 630,966. X-ray apparatus. PHILIPS LAMPS, Ltd. June 26, 1946, No. 19078. Convention date, May 13, 1942. [Class 98 (i)] Apparatus for medical examination of the kind in which the X-ray tube is movable parallel to the plane of the screen or other receiver of rays is characterized by the provision of means including a coupling between the tube and screen which causes the central ray always to strike the screen at substantially the same point upon displacement of the X-ray tube relative to the screen in the longitudinal direction of the support for the patient and brings about a simultaneous movement of the X-ray tube and screen in the same sense, parallel to and in the transverse direction of the said support. As shown, the table 3 is mounted in a frame 1, rotatable about an axis 4 by hand or by a motor in a casing 5, and also supporting pillars 6, 7 on which carriages 8, 10 travel. The carriage 8 has a sliding support 12 for the X-ray tube 9, and the carriage 10 carries the screen 11 or its equivalent on telescopic rods 14, 15. Counterweights (not shown) may assist the movement of the carriages 8, 10 when the table 3 is vertical, or the movement of the support 12 when the table 3 is horizontal.. The tube 9 is carried by a shaft 20 axially slid able in bearings on the support 12. A bush 22, which rotates with but slides axially on the shaft 20, and is held between the bearings, is fastened to a telescopic rod 23, the other end of which rests in a bush 32 pivoted by pins 25 on an axis passing through the centre of the screen 11. When the relative position of the carriages 8, 10 alters, the rod 23 takes up a new inclination and rotates the bush 22 and therewith the tube 9, so that the principal ray always strikes the centre of the screen 11. The telescopic rod 23 rotates as a whole in bearings in the bushes 22, 32 and carries at the tube end a gear-wheel 29 engaging a rack 30 fixed to the sliding shaft 20. A similar gear-wheel 33 on the screen end engages a rack 34 sliding in a bearing 35 attached to the bush 32. The end of the rack 34 engages a slot 36 in a bracket 37 on the screen carrier, and is fixed thereto by a boss 38. This arrangement allows freedom of movement when the inclination of the rod 23 changes, but also enables the rack 34 to control the horizontal sliding movement of the screen 11 in a frame 27 on the carriage 10. The same result may be achieved by connecting the rack to the screen by a crank, by providing a crank at right-angles to the shaft 23 with a link fastened by a universal joint to the screen carrier, or by providing gear-wheels linked by a flexible shaft and engaging a rack fixed to the screen. These arrangements may also apply to the lateral shift of the tube. The rod 23 or the screen 11 may have handles for controlling the movements.
