Patent GB-2250067-A (GB)
Title: Sealing apparatus
Inventor: BOWERS NORMAN KENNETH
IPC: F16J15/46
Filed: 1991-09-17
Abstract: A seal assembly for sealing a space between a rotary shaft (44) and a stationary member (10) includes a housing (66) having a bearing (90) that maintains the housing (66) true on the shaft (44). Seal assemblies (103, 105 and 107) axially spaced along the shaft (44) are connected via pressure relief valves (134) (Fig. 2) so that e.g. pressure above a predetermined limit across a first ring (103) passes to a second ring (105) and when the threshold at ring (105) is exceeded, pressure passes to third ring (107). In this way, at high pressures all three seal assemblies (103, 105 and 107) are active. A normally inactive back-up seal (109) may be provided. The seal assembly may be water lubricated. A split lap-jointed structure for a sleeve (110) forming part of the seal assemblies (103 to 109) and the curvature of the sleeve (110) relative to shaft diameter are also described. <IMAGE>

Title: Inhalation apparatus
Inventor: BALACHANDRAN WAMADEVA
IPC: A61M15/00
Filed: 1992-04-08
Abstract: An inhaler 1 has a housing 2 defining a passageway 9 for inhaled air. An aerosol dispenser 3 is arranged to be responsive to an electrical actuating signal to dispense into the passageway a substance to be inhaled. A sensor 14 produces the actuation signal in response to inhalation and comprises a membrane 15 of a polymeric piezoelectric material, such as PVDF, arranged to produce a signal voltage in response to flexure. A support member 16 holds the membrane in position relative to the housing at a location such that the membrane flexes in response to a change of air pressure in the passageway. The inhaler is primarily intended for medical dispensing of inhaled substances. As shown in Fig. 1, the membrane 15 normally lies in contact with a side wall 17 defining the passageway 9. In another embodiment, (Fig. 4), the membrane (54) is bonded to and flexes with an elastomeric diaphragm (53) exposed on one side to ambient air and on the other to air within the passageway. <IMAGE>

Title: Towed multi-band decoy.
Inventor: TUCKER TREVOR W
IPC: F41J2/00
Filed: 1992-06-26
Abstract: A towed multi-band radar decoy or target comprises a collapsible, airstream-inflatable device for providing gunnery practise or electronic countermeasure protection for aircraft against radars and radar-guided missiles by being towed on a line behind the aircraft and offering a more attractive radar target than the aircraft. The decoy or target can be deployed while an aircraft is airborne. The decoy is comprised of a sleeve (5), fig 2, of radar-transparent fabric having a tapered cylindrical shape and an open mouth at a narrow end (7), and clusters 1 of orthogonal trihedral corners formed from flat conductive surfaces 17 fixed inside and to said sleeve which can be folded and collapsed into a small space, and once inflated, for providing a radar reflective signature which exceeds that of a towing aircraft over predetermined angular aspects. <IMAGE>

Title: Sol-gel composition containing hydrolysable silicic ester for producing glassy coatings
Inventor: PATEL BIPIN CHANDRA MULJIBHAI
IPC: A61K6/896
Filed: 1992-07-08
Abstract: Glassy coatings are made by curing in situ a coating of a sol gel, xerogel or heat-consolidated gel composition comprising a hydrolysable silicic ester, 1-4 moles water per mole of silicon and a solvent e.g. alcohol, filled with a filler such as kaolinite or with fiat plates (1-2 mu m x 10-5 mu m) of mica, which may be coated with TiO2, Cr2O3 or Fe2O3 applied by CVD. The silicic ester may be silicon tetrahalide or tetraalkoxysilicon. Further fillers are laponite, zeolite, talc, vermiculite. The mica or talc may be coated with silane. The composition may also contain a metal alkoxide capable of participating in forming glass structures with the silicic ester, e.g. alkoxides of Na, Zr, Al and Ti. The composition may be cured to form the glassy coating by the use of laser radiation or a butane gas flame. Use is made of very miniature flames so as to avoid vital tissue when curing on a tooth. Part of the silicic ester may be replaced with other glass formers such as boron-based sol gels. The coating may be applied to teeth as a dental fissure sealant or varnish to protect restorations, or as an inherently coloured cosmetic coating, or as a prophylactic coating. in an application for slow drug release the coating may be charged with a drug, eg for treating dentine hypersensitivity or peridontal disease.

Title: Tracked canopy door with motor driven opening and closing mechanism
Inventor: AUGER TIMOTHY JOHN
IPC: E05D15/22
Filed: 1995-12-19
Abstract: A tracked canopy door 1, for example for a garage, pivots during opening and closing of the door about a generally horizontal axis substantially in the plane of the door and intermediate the top and bottom thereof. The axis about which the door pivots is able to rise and fall substantially in the plane of the closed door as the door is opened or closed. The door incorporates an opening and closing mechanism comprising a horizontal axle 7 about which the door can pivots, having toothed gears 11 at either end engaging tracks 13 mounted on the door jam, and a housing 3 containing a motor which rotates the axle 7. The rotating axle causes the door to lift or lower via the gears 11 on their respective tracks 13 and, due to friction in the mechanism, the housing and thus the door also rotate in the opposite direction to the axle. Limit switches can be used to control the extremities of movement, and the motor can be operated by an radio or infra-red signal.

Title: Security door entry-phone
Inventor: RICHARDSON LESLIE FRANCIS HENR
IPC: G08B15/00
Filed: 1996-02-08
Abstract: The security door entry-phone system has a receiver that accepts a cassette tape. When a caller rings he will hear a voice say "hello", at that point a criminal would probably withdraw and the security phone has done it's job. The owner, however, can elaborate on this by leaving a gap in the tape for the caller to speak before giving his/her reason why it is not convenient to come to the door followed with a final good-bye] Voices overlapping would make it no less realistic since this often happens in reality with these systems.
