Title: Fire alarm system
Inventor: YAMAUCHI YUKIO
IPC: G08B17/00
Filed: 1984-02-20
Abstract: A fire alarm system which detects a change in the physical phenomena of the surroundings caused by the occurrence of a fire, in an analogue form by a detector (1a, 1b... 1n), and samples the detection data periodically by a central signal station (10) to make determination of fire is disclosed.

Patent GB-2156044-A (GB)
Title: Control valve
Inventor: BOWER LEWIS ROBERT BARNES
IPC: F16K11/16
Filed: 1984-03-20
Abstract: A control valve has at least one valve arrangement (13, 14, 23, 26) located in a first valve body (10) with a supply port (16), exhaust port (30), and a delivery port (25), and is normally biassed to a position connecting the delivery port (25) and the exhaust port (30), while the supply port (16) is closed. The valve is manually displaceable, to close the connection between the delivery port (25) and the exhaust port (30) and upon further displacement to open connection between the delivery port (25) and the supply port (16). Also a valve arrangement located in a second valve body is provided with an inlet port connectable to a source of hydraulic fluid, an exhaust port, and a delivery port connected to the supply port (16) of the or each first valve body (10). The second valve arrangement is biassed to a position connecting the delivery port and the exhaust port, while the inlet port (16A) is closed. Manual displacement causes closure of the connection between the delivery port and the exhaust port, and upon further displacement, opens connection between the inlet port and the delivery port, to make fluid available to the supply port (16) of the or each first valve body (10). Hence a hydraulic pressure is only transmitted from the control valve when both valves, are actuated. <IMAGE>

Patent GB-2141821-A (GB)
Title: Pressure sensor
Inventor: SIKORA EDMUND SERGIO ROBERT
IPC: G01L1/24
Filed: 1984-04-25
Abstract: A pressure sensor comprises a first set of optical fibres (5) disposed in generally parallel planar relationship, a second set of optical fibres (7) disposed in generally parallel planar relationship overlapping the first set of fibres and extending transverse thereto, and means (15 - 25) for determining the light transmission loss of each fibre. In use of the sensor, the application of pressure on the sensor causes a slight bending of the fibres at the or each cross-over point of the two sets of fibres in the region of application of the pressure, with a resulting change in the light transmission loss of such fibres, thereby indicating that pressure has been applied. By identifying the particular fibres in the two sets whose light transmission losses have been changed, an indication of the location of the region of application of pressure may be obtained. Applications to keyboards, and to indicate the shape of the object applying the pressure, are mentioned. <IMAGE>

Title: Pipe connection/repair device
Inventor: NIMKE HELMUT E
IPC: F16L13/00
Filed: 1984-07-24
Abstract: A connecting device 10 for connecting together tubular members 18,20 is comprised of a resilient sheet member 12 in the form of a coil having at least partially overlapping surfaces 14. The inner diameter of the sheet member coil is less than the outer diameter of the members to be joined.

Title: Assembling an optical fibre connector
Inventor: CUTLER ALBERT ERNEST
IPC: G02B6/38
Filed: 1984-12-18
Abstract: A method for assembling a connector comprising two end members and a plurality of strands 1,2,3 of a deformable material extending between the end members, the strands having a substantially circular cross section, and the ends of the strands being attached to the end members so as to define a cage-like structure into which optical fibres may be inserted through the end members. The strands are positioned by arranging them within an external restraint such as a tube 4 and around a wire 8 of greater diameter than that of fibres to be connected together. The wire 8 and external restraint 4 are dimensioned such that the strands are forced to assume predetermined positions around the wire, the strands then being secured to the end members whilst held in said predetermined positions. Finally the wire 8 is withdrawn from between the secure strands 1,2,3 to leave a passageway between the strands into which fibres to be connected can be inserted. Spacer rods 5,6,7 are also shown. <IMAGE>

Title: Vehicle weighing apparatus
Inventor: HEWITT STEVEN JOHN
IPC: G01G19/02
Filed: 1985-07-24
Abstract: Apparatus for measuring weight transmitted by a vehicle wheel includes a pair of laterally spaced beams (12) with vertical webs (30) and upper and lower horizontal flanges (31,32) to provide lateral and torsional stiffening, tubular cross members (19) connecting the beams, and supports (13) for the ends of the beams. A load platform (10), with ramps (11) for the wheel, is carried on the cross members. During weighing, strains in the vertical webs (30) of the beams between the supports (13) and the cross members (19) are measured by semiconductor straing gauges (34,35) bonded to a flat surface (36) in the web. A stiffening box section (14) around the strain gauges reduces horizontal and torsional strain. Cut-outs (41,42) in the web above and below the strain gauges concentrate the vertical shear forces. Two mutually perpendicular strain gauges at 45 DEG  to the vertical compensate for torsion. A Wheatstone bridge circuit measures resistance changes, enabling the load on the apparatus to be determined after preliminary calibration. <IMAGE>

Title: Side by side concrete rafts with chamfered edges
Inventor: KENNEDY LESLIE JOSEPH
IPC: E01C5/08
Filed: 1986-04-04
Abstract: The concrete raft (10 Fig. 1) is a generally cuboid block of reinforced concrete having a flat upper surface 11. Each side face 13 of the block is chamfered at its upper and lower surfaces 14, 15. The block has a central vertical portion 16 between the chamfered portions, which abuts a similar vertical portion 16 of an adjacent block 10 when laid adjacent thereto. Rafts 10 are usually laid side by side to form a continuous surface for forming emergency runways for airports, or for providing docks or similar temporary surfaces. Typically rafts are laid on a bed of sand, which collects between the edges of the rafts and prevents accurate abutment of the side faces. Lower chamfered portions 15 ensure that this does not happen and upper chamfered portions 14 reduce the tendency of the raft upper surfaces to crack or the upper edges to spall. <IMAGE>
