Title: Data processing systems
IPC: G06F9/48
Filed: 1971-11-12
Abstract: 1348936 Program interruption SIEMENS AG 12 Nov 1971 [16 Dec 1970] 52534/71 Heading G4A A data processing system includes a priority exchange register whose contents indicate the priority level of the highest priority program awaiting execution, a priority status register whose contents indicate the priority of the program currently being executed, an interrupt register, and two comparators, the arrangement being that after each command of the current program has been executed a priority level is set in the interrupt register and that in order for the current program to be interrupted the priority stored in the exchange register must be greater than that in the status register and greater than or equal to that in the interrupt register. The system allows the effective priority level of the current program to be varied during its execution to prevent important sections from being interrupted. When an interrupt occurs an interrupt indicator is set and status data relating to the interrupted program and the previous state of the interrupt indicator (i.e. an indication of whether the program being interrupted has itself interrupted a further program) are stored in a storage region associated with the priority of the interrupted program. The priority of the interrupted program and its current interrupt limit are also stored but in a storage region associated with the priority of the interrupting program. The priority of the interrupting program is transferred to the priority status register and the interrupting program is executed. When a program finishes the interrupt indicator is examined. If this is set indicating that the program just finishing caused an interruption the priority and interrupt limit of the program which was interrupted are accessed from the storage region associated with the priority of the program which has just finished. The priority of the highest priority applying program is then compared with the accessed priority and interrupt limit. If the applying program has priority the accessed priority and interrupt limit are returned to store in a region associated with the priority of the highest priority applying program which is then run. Otherwise the status data and interrupt indicator are accessed from the storage region associated with the priority of the program which was interrupted by the program which has just finished and the previously interrupted program is run.

Abstract: 1357020 Gyroscopic apparatus SPERRY RAND CORP 12 Nov 1971 [19 Nov 1970] 52653/71 Heading G1C A gyroscope for sensing the rate of turn of a vehicle with respect to two orthogonal axes x, y, comprises a disc-shaped rotor 10 which, when rotated by a motor 21' about its spin or symmetry axis SA, floats within an enclosed cavity 11 containing fluid. The shape of the rotor 10 and cavity 11 causes the dynamic forces generated by the rotation to restrict rotor movement along the axes x, y. Movement of the rotor 10 along axis SA is restricted by raised spiral areas 50 on the otherwise flat surfaces of the cavity walls 15, 16. These areas 50 generate a pressure profile 49, the pressure being greatest along the axis SA. The rotor 10 may constitute the operative element of electric pick-offs which supply outputs proportional to tilting about the axes x, y. The pickoffs comprise pairs of capacitor plates, plates 30, 31 for example detecting tilting about the x axis. The rotor 10 may also constitute the armature of electric torque motors, the gyroscope being provided with pairs of coils which simulate tilting. Coils 40, 41, for example, simulate tilting about the y axis. This facility enables self-testing and calibration of the gyroscope.

Abstract: 1069740 Vibration dampers LORD CORP 31 Dec 1964 [6 Jan 1964] 53076/64 Index B2P 3B P9G  In a vibration damper 8 for suppressing vibrations in directions radial to the axis of rotation of a shaft 6, e.g. of a centrifuge 1, a non-rotating weight 10 is supported by a tension wire 71 to vibrate in radial directions with a natural frequency tuned to correspond with variable shaft speed frequency or a multiple thereof. A damper 8 is fitted to the centrifuge at each end of the shaft 6 which is driven by a motor (4), Fig. 1 (not shown), is journalled in bearings (7), and has a rotor (5) the wire 11 being anchored at one end to the casing 8 and at the other end to a disc 12 fixed to a bearing housing 13 slidable within a bore 14 in the housing 9. A key 15 in a slot 16 prevents the housing 13 from rotating the housing accommodating a ball bearing 17a the inner race 18 of which is fixed to a stub-shaft 19 connected to the shaft 6 by pivoted links 21 carrying centrifugal weights 22. As the shaft rotates the centrifugal force of the weights 22 applies an end thrust to the bearing housing 13 to tension the wire 11 with a force proportional to the square of the speed of rotation and since the vibration of the weight 10 has a natural frequency proportional to the square root of the tension in the wire 11 the natural frequency of the weight is directly proportional to the change in speed or rotation of the shaft. The wire 11 has negligible bending stiffness and the weight is substantial so that the frequency of vibration of the absorber weight is substantially proportional to the tension in the wire 11. In a modification, Fig. 3 (not shown), an impellor (23) on the shaft (6) develops a fluid pressure, which is proportional to the square of the speed of the shaft, and which is applied to the enclosed space between two parallel diaphragms (25), (26) the lower (25) of which has a greater area. The two diaphragms have their centres connected to the lower end of the wire 11. In a further modification, Fig. 4 (not shown), a vibration pick-up (27) is mounted upon the centrifuge (1) and has an output which is fed through a D.C. converter (28) and a D.C. amplifier (29) to feed a coil (30) and produce, in a force coil (31) connected to the wire 11, a force which is proportional to the square of the vibration frequency of the centrifuge.

Abstract: 1409716 Alarm systems MOVALARM Ltd 16 Nov 1972 [16 Nov 1971] 53251/71 Heading G4N [Also in Division H3] In an alarm system in which a television camera C provides an output video signal in response to changes in a scene under surveillance to operate an alarm device, the video signal is fed to a filter which removes information at line repetition rate and the output from the filter is fed to a resonant circuit having a resonant frequency which is higher than the field repetition rate to reject large areas of uniform brightness and also fine detail from transitions between bright and dark areas or vice versa so that only transitions from reasonably large objects will produce an output. The video signal is fed to a " sliding window " amplifier 3 which passes only a limited part of the signal, the part sliding up and down to accept small changes in bright and dark areas. The output from amplifier 3 is then fed to the filter and resonant circuit 4. In order to obviate the effect of synchronization pulses, the output from circuit 4 is gated off during field synchronizing pulses by a signal derived from circuit 5. The output from 4 is fed via an amplifier 6 to an average detector 7 to produce a signal which fluctuates in dependence on any disturbances detected in the field of view of the camera. This signal is fed via a bandpass amplifier, which eliminates very slow or very rapid changes, to a detector and indicator 9, 10. The output of 9 may connect one of a number of cameras to a common monitor, or a number of monitors may be employed.
