Patent GB-2040549-A (GB)
Title: Improvements Relating to Laser Apparatus
IPC: B23K26/00
Filed: 1979-12-07
Abstract: A laser apparatus comprises a laser oscillator including a laser medium (1), positioned between a pair of oscillator mirrors (2, 3) defining an optical cavity, a laser amplifier including laser media (8, 14) positioned downstream from the output of the laser oscillator, an optical isolator (7, 12) downstream of the laser oscillator, and a narrow band transmission filter (10) in the laser amplifier tuned to the output frequency of the laser oscillator. The combination of the optical isolator (7, 12) to prevent the laser radiation resulting from the laser oscillator and the majority of any radiation of the preferred wavelength setting up oscillations in the amplifier, and the narrow band transmission filter (10) to prevent the transmission of laser radiation at any frequency other than the preferred wavelength in the laser amplifier, results in the suppression of all oscillation in the laser amplifier as a result of reflection from a work piece (16). <IMAGE>

Title: Radio pager with reduced power consumption
IPC: H04Q1/30
Filed: 1980-05-08
Abstract: A radio-paging receiver gives a signal responsive to the receipt of a predetermined sequence of tone signals. The sequence is identified by an identification number stored in and read out of a read-only memory (ROM), which is a high-power consumption circuit. The remainder of the radio-paging receiver is constructed from low-power consumption components. Other than the readout of the ROM, all other of the circuit operations are carried out by the circuits having low-power consumption components. The high-power drain read-only memory is operated only momentarily and then its output is stored in low-power consumption circuits, for future reference. This way, the high-power drain operations are restricted to extremely short periods, with no energy wasted in a waiting time.

Title: Storage tower for vehicle panels
IPC: B65G37/00
Filed: 1980-06-12
Abstract: Vehicle panels such as roofs 1 are stored in a closely spaced fashion in a vertical stack. In the illustration, they are fed into the tower from the bottom and removed from the top, but they could equally travel in the opposite direction. In the illustration, there are two sets of conveyors. First, a set 5 of four arranged near the corners of the stack which carry regularly spaced support members. Second, a set 7 of four transport conveyors arranged near the centre of the stack for lifting successive panels. The transport conveyors 7 lift each panel from a lower conveyor 2 and carry it up until a panel in the next highest position is sensed: the transport conveyors then reverse direction to pick up the next panel. The support members on the conveyors 5 pivot up clear of the panels as they rise through the stack and then drop back under gravity. The panels are removed from the stack by an upper conveyor 3. <IMAGE>

Patent GB-2108664-A (GB)
Title: Device for detecting inclination
Inventor: OKUYAMA SHIGEAKI
IPC: G01C9/20
Filed: 1982-01-12
Abstract: A machine body inclination detector device has a float 13 constructed such that the buoyancy of the float does not undergo a great change relative to the mass when the inclination of the liquid level varies. This is achieved by making it hollow and providing weights 16 so that the top of the float is close to the level of the liquid 17. Since the buoyancy changes are small the motion of the float is damped. Partition wall 20 in the float has a small bore to damp motion of the fluid. The position of the float relative to the casing 9a, 9b, 10 is detected by proximity switches operated by steel elements 14, the switches operating a control circuit 19, V, for cylinder 6 which will thus correct the inclination of the casing and the implement on which it is mounted (Fig. 1, not shown). <IMAGE>

Patent GB-2106313-A (GB)
Title: Emission-electron microscopy
Inventor: TURNER DAVID WARREN
IPC: H01J37/285
Filed: 1982-01-15
Abstract: An emission-electron microscope comprises an evacuated chamber (70) with a superconducting magnet (73) at one end generating a region of very high field strength. In this region a specimen is mounted and the surface of the specimen is irradiated with photons, typically x-ray or hard ultraviolet, from a source (75). As a result the specimen emits photo- electrons. The magnetic field is axially symmetrical along the length of the chamber (70) and emitted electrons spiral about the lines of force travelling down the chamber into a region of lower magnetic field controlled by electro-magnet coils (81). Transverse kinetic energy of the electrons is converted into energy along the lines of force of the magnetic field and the divergence of the magnetic field lines causes electrons to produce on a detector (79) an expanded electron image indicative of the distribution of electron flux across the surface region of the specimen. The emission- electrons may be produced by other stimulation methods, for example neutral atoms or heat (thermal electrons) and arrangements may be provided to permit only electrons of predetermined energy reaching the detector. <IMAGE>

Title: Hollow glazing panels
Inventor: CHERTON YVAN
IPC: E06B3/67
Filed: 1983-08-05
Abstract: A hollow glazing panel may be manufactured by adhering first and second vitreous sheets 10, 11 and a heat-shrinkable plastics foil 4 to marginal spacing means comprising first and second metal spacer frames 1, 6, the foil 4 being located with a marginal zone sandwiched between opposing faces of the frames and being heat shrunk at a stage after it has been firmly bonded to at least one of them, so that in the final assembly the foil is held taut between and in spaced relation to the sheets. The foil 4 is securely adhered to at least one of the frames by means of a thermosetting adhesive 5, 8 which forms a substantially rigid foil-to-frame joint. This foil adhesive is applied to the frame before being brought into contact with the foil 4 and is subsequently allowed or caused to set in contact with the foil 4 before the foil is heat-shrunk. For firmly jointing the vitreous sheets 10, 11 to the metal frames 1, 6 use is made of adhesive 12, 13 which when set forms joints which are more elastic than said foil- to-frame joint. <IMAGE>
