Patent GB-2104292-A (GB)
Title: Time switch
Inventor: DUNNING GEORGE ERNEST
IPC: G04C23/14
Filed: 1981-05-14
Abstract: A magnet 4 is attached beneath the hour-hand of a conventional analogue clock so as to sweep in close proximity to a reed contact unit 1, secreted beneath the surface of the clock face. Thus at a fixed time every 12 hour cycle, contacts of the unit 1 are changed over to the N/O position to cause a motor 5 to turn a cam 6. The cam 6 actuates a microswitch 2 to the N/O position causing the motor 5 to be turned off until the magnet 4 has moved sufficiently far away from the contact unit 1 for its contacts to change back to the N/C position. The motor 5 is driven again until the cam 6 actuates the microswitch 2 to the N/C position. The motor 5 then remains stationary until the hour hand once again reaches the contact unit 1 whereupon the cycle is repeated. A 12 hour clock is thus transformed into a 24 hour time switch. <IMAGE>

Title: A process for the advance indication of breakdowns or faults in a tribological (lubrication) system
Inventor: FODOR JOZSEF
IPC: G01M99/00
Filed: 1982-08-31
Abstract: After the machinery has been run in samples are taken from the lubricant and the quantitative values of the wear products and external contaminants in normal use of the tribological system are determined and the particle number characteristics of the wear products and contaminants of this normal wear are determined. These values are then treated as the permissible values for normal operation and in an operating tribological system samples are taken periodically and analysed to monitor whether the quantity and particle size of the wear products and contaminants remain within the range of permissible values. Should the range of permissible values be exceeded a particle morphological analysis is performed and the system is classified as faulty in the presence of spherical fatigue particles and/or chip shaped particles characteristic of abrasive wear.

Patent GB-826418-A (GB)
Abstract: 826,418. Gyroscopic apparatus. SPERRY GYROSCOPE CO. Ltd. May 11, 1951 [May 16, 1950], No. 12186/50. Class 97(3) [Also in Group XXXV] In a navigational computing system in which the aircraft polar co-ordinates are derived with respect to the Earth's centre, the electric outputs from three gyrostabilized accelerometers are employed to precess the associated horizontal and.vertical gyroscopes so as to maintain them aligned with the local horizontal and vertical axes as the craft progresses round the Earth. The processional forces are applied from a platform having three degrees of freedom about three mutually perpendicular axes, automatically controlled so as to maintain alignment between the gyroscopes and the platform. The navigational system, the accelerometers and the gyroscopes are those described in Specifications 740,349, 804,847, 804,849 and 826,417 [all in Group XXXVIII]. As shown, the vertical and horizontal gyroscopes 10, 11 are mounted in a common frame 7, Fig. 2, together with the accelerometers 45, 46, 91. The latter, in association with the computer 100, derive the craft co-ordinates and supply voltages w 1 , w 2 , w 3 , the first of which is applied to the torque motor 41<SP>1</SP> which precesses the azimuth gyroscope 11 in the horizontal plane, while w 2 , w, react through the torque motors 41, 40 on the gyro-vertical 10 to maintain it in both the North-South and East-West vertical planes. The speeds of precession determined by w 2 , w 3  are such as to allow for the craft movement and the Earth's rotation and thus maintain the gyroscope axes parallel to the local co-ordinate axes. Frame 7 is mounted in the gimbal system 8, 9 which is rotated about the mutually perpendicular axes by the servomotors 30, 32, 34; 32, 34 control the gimbals about the horizontal axes HG, JK in response to signals from the pick-off 5, 6, on the gyrovertical 10, which are passed through the mixer-resolver 20. Motor 30 controls the gimbals about the vertical axis EF in response to signals from pick-off 6<SP>1</SP> on the azimuth gyroscope 11. Pick-off 5<SP>1</SP> controls torque motor 40<SP>1</SP> to maintain the rotor axis of gyroscope 11 horizontal. Specifications 826,419 and 826.420 also are referred to.

Title: Method and apparatus for projecting a liquid steam with entained particles
Inventor: KNIGHT DESMOND MARVIN
IPC: F04F5/10
Filed: 1983-01-07
Abstract: Apparatus for projecting a stream of liquid and particles onto a body to effect treatment of the body comprises a cylindrical chamber (10) which defines an axis (12). A liquid inlet tube (14) defines an inlet passage (15) for the passage of liquid into the chamber, a second passage (19) provides a path along which abrasive particles can be fed to the chamber. A longitudinal centreline of the passage (19) does not intersect the axis (12) and does not intersect between the open end of the first passage and the chamber outlet so that particles are not projected directly towards the stream of liquid. When the apparatus is in use, liquid is supplied under high pressure so that a pressure in the chamber is established which is below that of the atmosphere. Particles which enter the chamber are drawn along the outside of the tube (14) due to the pressure differential and are entrained only in the outer parts of the stream of liquid so that the stream is not significantly disrupted. <IMAGE>
