Patent GB-2237872-A (GB)
Title: Temperature sensor
Inventor: NADEN JAMES MARK
IPC: G01K5/52
Filed: 1989-11-08
Abstract: A temperature sensor comprises a Fabry-Perot cavity formed between the end of the single mode fibre 14 and the surface of a silicon reflector 15 is formed as one sidewall of a channel 17 in a block of silicon 18. The other sidewall 19 of the channel 17 is of lesser height from the base of the channel and terminates a portion 20 of the block which provides an anchorage for the end of the fibre 14. Wavelength modulated light is propagated down the fibre and changes of temperature alter the optical path length of the cavity. The light reflected in the fibre will form interference fringes and the relative magnitudes of the harmonic components in the reflected light are detected and used to determine the temperature changes. The sensor may be formed as a bathythermograph. <IMAGE>

Title: A ticketing system
Inventor: PYE RAY ERROL
IPC: G09F7/04
Filed: 1991-10-07
Abstract: A ticketing system comprises a base plate 1 and a plurality of signs 2 carrying information relating to a product to be sold. In particular, there is provided, with each base plate 1, a set of signs 2 carrying numerals which can be combined to display any desired price for the product and letters which can be combined to produce the name of the product. The base plate 1 is made of metal and the signs 2 are magnetised. In this way, the desired signs can be placed on the defined areas of the base plate and will remain there due to magnetic attraction. In order to reduce the likelihood of the signs slipping down when the plate is 3 vertical, the areas 3, 4, S and 6 are each provided with a lip 7 upstanding out of the plane of the plate 1 to form an abutment against which the signs 2 can be placed. The lip 7 is preferably formed by deforming the plate 1 by punching from the back side thereof to produce a ridge. However, the lips 7 could, alternatively, be formed by thin rods of metal or other material fastened to the base plate 1 by any suitable means. <IMAGE>

Title: Oil-operated tensioner
Inventor: SUZUKI TADASU
IPC: F16H7/08
Filed: 1992-10-22
Abstract: A chain tensioner 10 utilizing oil as an operating fluid comprises a housing 12 having a vertical bore and a plunger 13 projecting upward through an opening at the upper end of the bore and urged by a spring 15 in the projecting direction. The plunger 13 has an internal oil reservoir 32 formed near its upper end, a passage 34 leading from the reservoir to a high-pressure oil chamber 14 formed by the housing and plunger, a check valve 38 preventing flow from the high-pressure chamber to the reservoir, and an opening 17 permitting flow of oil into the reservoir. A second oil reservoir 40, annular in shape, is formed in the housing 12 at the location of the opening to provide an oil seal between the plunger 13 and the wall of the bore. This oil seal prevents air from flowing between the plunger and the wall of the bore into the high-pressure chamber 14. In one embodiment, an auxiliary spring (42, Fig 2) is located in the second oil reservoir. <IMAGE>

Title: Anti-rotation wiper ring
Inventor: GAUCHER JOHN J
IPC: F16J15/32
Filed: 1992-12-21
Abstract: An anti-rotation wiper ring (40) for mounting in a pump equipment gland concentrically to the equipment pump rod, has a wiper lip for preventing debris from being carried on the rod retracting within the equipment. A structure prevents the ring from rotating inwardly toward the rod and possibly outwardly thereafter out of the pump. In one embodiment, the wiper ring flange (44) is held in the gland receiver groove via an anti-rotation anchor (70) on the flange bottom surface mating with a gland locking groove on the bottom surface of the gland receiver groove. Additionally, a stabilizer device (52) is formed on the ring ID and prevents the ring's inward rotation. The stabilizer has standoffs to allow the passing rod to glide by while a recession above the standoffs reduces drag. Reliefs between the standoffs harmlessly pass any pressure which may escape the pump piston seal. A static seal (42) keeps a potential leakage path closed in between the wiper ring OD and gland receiver groove ID. <IMAGE>
Patent GB-2263839-A (GB)
Title: Still video camera
Inventor: AOKI HARUMI
IPC: H04N5/77
Filed: 1993-03-16
Abstract: A still video camera has a pickup circuit 34 which receives a signal produced by an image sensor 32. In a record mode, an image record/playback circuit 35 processes the video signal for recording on a disc 37 via a magnetic head 36. In a replay mode, the record/playback circuit processes a played back signal from the disc for playing back via an AV output connector 26. When a record mode is selected, actuation of a release switch 20 initiates recording. When a replay mode is selected, actuation of the release switch 20 initiates the start of reproducing the recorded video signals, further actuation stops the reproducing. Thus, unnecessary power consumption is avoided. <IMAGE>

Title: Installation of battery cell in e.g a submarine
Inventor: MIETZ ECKART
IPC: H01M2/10
Filed: 1993-10-11
Abstract: For simple installation and shock-proof retention of a battery cell (1) in a submarine, the underside of the cell base 3, interrupted by a shoulder, is glued to a large-area hooked footing 4 made of steel, which is clamped to a ship's hooked rail 9 permanently welded to the hull of the ship. Compression forces are transmitted directly to the hooked footing in the centre-of-gravity line M. Tensile forces are transmitted via the container walls 2, 3 and are elastically absorbed by tapered sections 7 of the hooked footing in the boundary region of the base. The steel, one-piece hooked rail of the submarine reacts elastically to shock forces and plastically to overload and thus protects the ship's hull and the cell. <IMAGE>

Title: Improvements in hydraulic braking systems for vehicles
Inventor: FARR GLYN PHILLIP REGINALD
IPC: B60T8/42
Filed: 1993-10-29
Abstract: An hydraulic braking system for a vehicle comprises a front wheel brake (4), a rear wheel brake (6), inlet and outlet valves (13, 14 and 11, 12) associated with the wheel brakes, and a pump (20) and expander chamber (26). When front wheel (5) tends to skid (ABS), valve (13) closes and valve (11) opens and fluid is dumped to the expander chamber, and when it recovers valve (11) closes and pump (20) is energised to return fluid from the chamber. When the wheel (5) tends to spin (TC), valve (13) closes, valve (12) opens and the pump is energised and draws fluid from the circuit associated with the rear wheel (7). When the vehicle is facing up-hill, a sensor will cause the pump to be energised, inlet valves (13, 14) to be closed and outlet valve (12) to be opened, so that fluid is transferred from the rear brake (6) to the front brake (4). <IMAGE>
