Title: Overload protection in gearing units for use with mining apparatus
Inventor: BOHLE WERNER
IPC: E21C35/04
Filed: 1984-06-07
Abstract: A gearing unit with planetary gearing 3 employs a load sensor in the form of a stationary pin 34 provided with a strain gauge 33 easily accessible via a bore 40 in its casing 28. The pin 34 bears on a rotatable component 27 of the planetary gearing 3 to hold this component 27 stationary during operation and is subjected to force proportional to dynamic loading on the gearing 3. On overload detected by the gauge 33, drive is stopped, eg. by actuation of an electromagnetic valve to supply pressure fluid to release a clutch, or the mineral winning machine driven by the gearing unit is withdrawn from the mineral face. <IMAGE>

Title: Method and apparatus for eliminating boundary layer separation from flight vehicles
Inventor: CLARK DR JAMES
IPC: B64C21/10
Filed: 1984-09-19
Abstract: The wing of an aircraft is coated with a layer (26) of material emitting alpha and/or beta particles. Emission is controlled by the signal applied to superimposed semiconductor layers (28, 30). A probe is mounted in the surface of the aircraft wing and may consist of 1,000 turns of fine wire on a ferrite rod. The probe detects electromagnetic radiation generated in the presence of turbulence. The amplified signal from the probe controls a switching circuit (Fig. 2) providing the controlling signal to the semiconductor layers (28, 30), whereby particle emission is enabled on detection of turbulence, thereby to reduce skin friction and reduce the turbulence. The use of the probe to cause energisation of a warning device in the aircraft cockpit to indicate inpending stall is also disclosed. <IMAGE>

Patent GB-2191292-A (GB)
Title: Measuring equipment
Inventor: ALLEN THOMAS JAMES
IPC: G01K15/00
Filed: 1986-06-07
Abstract: The forward voltage drop at constant current is used as a measure of the temperature of sensing diodes embedded in concrete. In a calibration process, the response of the sensing diodes to temperature is measured and memorized at two known temperatures. A constant current is passed from an FET 1 having a filtering capacitor 2 and a pair of protection diodes 3 to a sensing diode 4. Another constant current is passed through a standard resistor 5 from a second FET 6. A series of incremental resistors 7 are switchable into circuit parallel with the resistor 5 via switches 8. The difference between the voltage across the diode 4 and that across the resistors 5,7 is amplified in a variable gain amplifier 9 and the output signal is passed via an analog to digital converter 10 to a central processor unit 12. The diode 4 is subjected to two known temperatures and two corresponding voltages are developed across it by the constant current. Memory 12 is used to memorize the results subject to the full range of multiplication increments of the amplifier 9. The best fit of the differences is selected to calculate the slope and offset of a linear voltage-temperature characteristic which is used in the subsequent measurement. A number of diodes are thus readily calibrated and may be used as disposable temperature sensors.   <IMAGE>

Patent GB-2180094-A (GB)
Title: Discharge tube arrangements
Inventor: MAITLAND DR ARTHUR
IPC: H01S3/097
Filed: 1986-08-21
Abstract: A discharge tube arrangement includes a gas-filled discharge tube 15, coaxially surrounded by a capacitor 20 and by a switch which is a toroidal discharge tube 16. Initially, the toroidal discharge tube 16 is non-conducting, and a potential is applied at 26 to charge the capacitor 20. When it is desired to trigger the first discharge tube 15, a pulse of high frequency energy is applied to a coil 23 wound around the outer circumference of the toroidal discharge tube 16. This initiates a glow discharge within the toroidal tube 16, thus lowering its breakdown potential. Because of the potential difference applied between two circular ring electrodes 17 and 18 within the toroidal tube, breakdown of the gas filling occurs to give an annular discharge, and it becomes conducting. The stored charge of the capacitor 20 is discharged principally through the discharge tube 15 causing breakdown of its gas filling and establishment of a discharge. The coaxial symmetry of the arrangement gives a low inductance circuit and an arrangement which is physically compact. In another embodiment of the invention an annular discharge is arranged to cause excitation of a laser active medium. <IMAGE>

Abstract: Apparatus for determining the prospective short circuit current between any two points in an electrical installation (not shown) comprises a micro-processor (11) for comparing the voltage at the peak value (14) of a half cycle of the operating voltage before and after the switching of a thyristor (3), the switching causing a test current to flow between the two points by way of two terminals (1,2) and an impedance (20). The voltage is pre-sampled at a predetermined pre-sampling point (16) during the half-cycle and a variable gain amplifier (5) amplifies the voltage signal with again depending on the value of the voltage at the pre-sampling point (16). The micro-processor (11) estimates, from the value of the voltage at the pre-sampling point (16), the likely value of the voltage at the peak value (14), and adjusts the gain of the amplifier (9) to make the change in voltage at the peak value (14) greater than a pre-set threshold value. <IMAGE>

Title: Solenoid valves
Inventor: KESSLER DE VIVIE ACHILL
IPC: F16K31/06

Abstract: A tank ventilation valve for the metered admixture of volatilised fuel from the tank to the fuel-air mixture for an internal combustion engine comprises a valve housing (10) with inflow and outflow nipples (11, 12), between which is arranged an electromagnetically actuable valve (21). The inflow nipple (11) is connectible with the ventilation nipple of a fuel tank and the outflow nipple (12) with the induction duct of the engine. To prevent running-on of the engine after switching-off the ignition, the valve (21) is constructed so that it is closed when solenoid (16) is de-energised. For this purpose, the valve (21) is formed as an annular passage (23) which defines an annular double seat (22). The valve member has the form of an annular washer (26) of magnetically conducting material and is loaded by a spring (33) acting in the valve closing direction. The annular washer at the same time forms the armature of the electromagnet (13).
