Title: Tunnel current probe moving mechanism having parallel cantilevers
Inventor: KAJIMURA HIROSHI
IPC: B81B3/00
Filed: 1990-07-12
Abstract: A tunnel current probe moving mechanism includes a silicon substrate 1a to be placed in contact with a sample surface and having U-shaped notches 7a-c to form first cantilevers 2a, b, second cantilevers 3a, b and a probe cantilever 4a. The cantilevers are of PZT or other piezoelectric material and have drive electrodes to drive a probe group 1000a on the cantilever 4a in a scanning pattern parallel to the sample surface and to keep the probes at constant distance from the surface by a feedback circuit working from the tunnelling current. The cantilever arrangement gives a rectilinear rather than arcuate scan pattern and the whole device can fit between the sample and the lens of an optical microscope used for setting up. The device may include a data memory for the scan results from the multiple probes. <IMAGE>
Patent GB-2247990-A (GB)
Title: Antennas and method of manufacturing thereof
Inventor: MEADOWS BARRY
IPC: B29C65/20
Filed: 1990-08-09
Abstract: An antenna array is fabricated from an upper plate 1 consisting of an array of stepped horn elements 3 and a lower plate 2 comprising a waveguide structure 5. The two plates are attached tog et her by means of heat welding or solvent welding. In the case of heat welding the lower plate 2 is provided with a pattern of ribs (11, Figs 6 and troughs and grooves, the material of the ribs being caused to 7) and the upper plate 1 is provided with corresponding flow into the troughs following application of heat to the interface to the two plates, thus causing the two plates to become attached. In the case of solvent welding, the rib and trough formations are omitted. The mating surfaces of the plates are brushed with dichloromethane and brought into abutment, causing the plates to become attached together. Subsequent to attachment, the structure is immersed in an electroless copper plating bath so that a thin film of copper is deposited on the exposed surfaces of the structure. Thus any imperfections in the flatness of the mating surfaces which would otherwise cause undesirable leakage of microwave radiation are effectively compensated for by the copper film. Alternatively silver or aluminium may be used to plate the structure. <IMAGE>

Title: Optical memory using optical fibre waveguides as second harmonic generator
Inventor: KASHYAP RAMAN
IPC: G02F1/383
Filed: 1990-09-14
Abstract: An optical memory has an array of phosphorus-germania doped silica optical fibre waveguides 2-5 capable of self- seeding by an optical signal from a laser 6, at a first frequency coupled a fibre by lens 8 to provide second harmonic (SH) generation. The efficiency of the SH generation is dependant on the intensity of the laser seeding signal which determines the memory state of the seeded fibre. The memory state of a fibre is read by introducing a probe signal from the laser 6 into the fibre and detecting the intensity of the second harmonic by means of a photodetector 12 after focusing by lens 10 and filtering out the remnant probe signal with a filter 14. <IMAGE>

Patent GB-2270472-A (GB)
Title: Apparatus for applying compression to the limbs
Inventor: SCHILD ROLF
IPC: A61H23/04
Filed: 1993-07-07
Abstract: The apparatus comprises first and second inflatable means for enveloping regions of a limb means for sequentially inflating the said means directly from a common source and non-return valve means for preventing deflation of the first means during inflation of the second. Restrictor means may be located in the pressure line to the second inflatable means with a downstream bleed so that said means can reach a steady state pressure less than that of the source. The pressure in alternately inflating compression means on respective limbs can be monitored by connecting a differential pressure sensor therebetween and determining from the polarity of the differential pressure valve which of the compression means is being currently monitored. The operation of a limb-enveloping inflatable sleeve which is repeatedly inflated to a preset pressure and then deflated is monitored by monitoring the rate of pressure increase during inflation, comparing this rate with a predefined limit rate and providing an alarm if the rate falls outside said limit rate.

Patent GB-939753-A (GB)
Abstract: 939,753. Controlling gas burners. G. KROMSCHRODER A.G. July 4, 1962 [April 26, 1962], No. 25623/62. Addition to 904,179. Class 75 (1). A flame safety control system for a plurality of main burners 20, 20<SP>1</SP>, 20<SP>11 </SP>comprises a plurality of pilot burners 13, 13<SP>1</SP>, 1311 having thermocouples 15, 151, 1511 controlling relays 70<SP>1</SP>, 70, 10<SP>1</SP>, the arrangement being that if any one pilot burner is not burning its associated relay energizes an ignition transformer 11 and de-energizes a main gas valve 18. The contacts 8, 9; 76, 77; and 78, 79 of the relays 10<SP>1</SP>, 70, 70<SP>1</SP> are in parallel and connect the primary winding of the ignition transformer to the mains supply. The secondary winding is connected to sparking electrodes 12, 12<SP>1</SP>, 12<SP>11 </SP>at the pilot burners. The contacts 16, 17; 72, 73 and 75, 74 of the relays 10<SP>1</SP>, 70, 701 are connected in series and connect the electromagnetic main valve 18 to the mains supply. The circuit also includes a monitoring relay 30<SP>1</SP>, a thermal cut-off 7, a thermostat 4, a pressure switch 26 and a rectifier 56. The Figure shows the condition of the relays when all the burners are burning. On closing a mains switch 1 current passes through the exciter coil of the thermal relay 7 to contacts 35, 33 of the monitoring relay 30<SP>1</SP>, closed contacts 9<SP>1</SP>, 81 of relay 10<SP>1</SP>, contact 34 of the monitoring relay 30<SP>1</SP>, thermostat 4, pressure switch 26 and energizes the rectifier 56 so that the coil of the monitoring relay 30<SP>1</SP> is excited and its three contact sets 35-36, 31-32 and 33-34 close. The ignition transformer 11 and a pilot gas valve 14 are therefore energized through contacts 31-32. Contacts 35-36 cause a further current to pass through the exciter coil of the thermal cut-off 7 from a tapping 37 on the ignition transformer 11. This current causes the cut-off to de-energize the circuit after a predetermined time. Contacts 33-34 hold the monitoring relay 30<SP>1</SP> energized. The pilot burners ignite and their thermocouples actuate their relays 10<SP>1</SP>, 70, 70<SP>1</SP>. The last relay to operate energizes the main gas valve 18 to supply the main burners and de-energizes the ignition transformer. The further current through the coil of the thermal cut-off 7 is thus cut-off. If any of the thermoelectric currents should fail the associated relay shuts-off the main burners and initiates the ignition of all the pilot burners. The exciter coil of the thermal cut-off 7 again carries the current from the tapping 37 of the ignition transformer and shuts down the system if the thermoelectric current is not restored within the predetermined time.

Title: Retractable point system for a dart
Inventor: PICKUP JEFFREY
IPC: F42B6/00
Filed: 1993-08-05
Abstract: A novel dart (10) is equipped with a dart point contraction system which allows the dart point (14) to contract into the body (11) or barrel of the dart as when the dart point (14) impacts wire, or staples and the like which surmount boundaries of denominated regions of a dartboard. The dart body (11) defines a cylindrical cavity (33) into which the downstream end of the dart point (14) can reciprocatingly travel since it also is cylindrical and comes to rest against the dart body (11) at the end of its travel. It is as a result of the kinetic energy of flight that even though the dart point (14) may have impacted a boundary wire or even a denominated region of the dartboard, that "bounce-out" is inhibited by the cylindrical portion (20) of the dart point (14) travelling in the cylindrical cavity (33) of the dart body (11) when impact occurs. <IMAGE>
