Patent GB-2239168-A (GB)
Title: Mascara brush
Inventor: FITJER HOLGER
IPC: A46B3/18
Filed: 1989-12-21
Abstract: The invention relates to a mascara brush with bristles bound by twisting in a twin-layer wire core (2), the bristles consisting of multiple fibres (3) bound by means of a solvent-soluble binding agent. Furthermore, the invention relates to a method of manufacture of the mascara brush, wherein the bound multiple-fibre bristles (3) are bound by twisting into the wire core (2) and, subsequently, the binding agent is dissolved out of the multiple fibres with a solvent, the bristles thereby being separated into individual fibres (4). In this way it is possible to obtain a dense array of fibres at the brush surface. <IMAGE>

Title: Hydraulic displacement system
Inventor: SOMERTON BRUCE EDWARD
IPC: F15B15/16
Filed: 1991-05-16
Abstract: A displacement system particularly for a domestic lift for disabled people has first and second single acting hydraulic cylinders with rams extending in opposite directions between points which are to be relatively displaced such as a part which is to be lifted fixed to the free end of the ram of the first cylinder and a fixed anchorage point for the free ends of the rams of the second cylinders. When fluid is displaced out of the first cylinder into the second cylinders all of the rams are drawn into the cylinders and the position of the cylinders themselves is displaced relative to the fixed point.

Patent GB-2251326-A (GB)
Title: Communication system
Inventor: GIBSON DAVID WARREN
IPC: H04B11/00
Filed: 1991-12-12
Abstract: A communication system, particularly suited for communication between divers, can transmit information in an echoing environment in discrete packets, timed so as to minimise distortion caused by echoes. A transmitting station sends a pulse to a receiving station. The receiving station times the interval between receipt (t0) of the pulse and of its first echo (t1) and the interval between receipt of the pulse (t0) and of its last echo (t2). The timing information is then sent to the transmitting station. The data is then transmitted in packets of duration less than the time interval to the first echo (t1-t0), and with an interval of t2-t0 between the end of a packet and the start of a further packet. If no echoes are detected then information signals may be transmitted continuously. In general, the system can transmit information bi-directionally. <IMAGE>
Patent GB-2261508-A (GB)
Title: Immunodiffusion or immunoelectrophoresis methods
Inventor: BRADWELL ARTHUR RANDELL
IPC: G01N37/00
Filed: 1992-04-03
Abstract: Invention relates to improvements in the detection of the presence of complementary agents in samples, particularly extractable nuclear antigens, by monitoring the formation of a precipitate or light scattering matrix. The method and apparatus are particularly concerned with the control of the application of the samples to a test body (11), normally a gel. By applying the samples to the surface of a test body and removing excess liquid, the permeation of particulate matter into the test body can be substantially eliminated. In conventional methods such matter can smother the results of a test. The careful control of the regions to which the samples are applied has further useful advantages in speed and improved detectability when the effective separation of the samples are reduced by interlocking the sample application regions. A mask (10) is proposed as the most advantageous method of controlling the regions of application. <IMAGE>

Title: Testing of fuel tanks and pipework. Valves.
Inventor: RISBRIDGER BARRY C
IPC: F17D5/02
Filed: 1993-04-01
Abstract: A method of testing the integrity of fuel lines 2 connecting a fuel tank 1 with a fuel dispensing pump 5 and vent lines 7 from the tank is described. In the case of a suction line 2 from the tank to the pump, the method involves temporarily plugging the inlet port of an elbow connector 3 from the tank to the pump, isolating the pump 5 from the suction line 2 and pressure testing the line by connecting a pressure testing device to a sealable access point at the elbow 3 or at an underpump valve 6. The tank is pressure tested by closing the vent line 7 with a shut off valve 8, closing the suction line 2 either at the elbow 3 or at the underpump valve 6 and introducing a pressure fluid into the vent line. Also described are specific valve constructions for facilitating the testing of fuel lines and fuel tanks (Figs 4, 5, 6). In Fig 3D, a filter element (113) is mounted in the elbow, a support flange (132) being spring-urged against a seat (32). The filter is removed while the fuel lines are tested. <IMAGE>

Title: A self-retaining device to facilitate the inhalation of gas to human beings and animals
Inventor: STEWART DAVID
IPC: A61M16/01
Filed: 1993-05-05
Abstract: A device for the delivery of gas including anaesthetic vapours particularly to children comprises a teat (6), body (1) and seal (2) closely applied to the face, sealing without excessive pressure around the nose to prevent the escape of gases towards the eyes. The seal may encircle the oral as well as nasal airway. The mask is largely retained by the child although straps may be provided. Due to the progressive change in the morphology of the face during the first 4 years of life, a range of masks is necessary to ensure an adequate seal. A port and connectors are provided to allow connection to all types of gas delivery tubing or monitoring equipment. An oropharyngeal airway may be substituted for the teat. <IMAGE>

Title: Determining nominal resistance and measuring current for temperature detection of electromagnetic coils.
Inventor: GRUENER MANFRED
IPC: B41J2/30

Title: Two part adhesive pack;connection of electrical wires.
Inventor: MAYES PETER ROBIN
IPC: B65D81/32
Filed: 1993-12-24
Abstract: A two-part adhesive pack comprises a sealed tubular capsule formed into an hour-glass shape body providing separate capsules, 3, 4 connected together by a hollow neck 2, into which pre-measured quantities of resin or paste and hardener adhesives compounds have been introduced, and which are separated by a fold (7, Figure 2) in the neck of the capsule body providing an air-tight seal. Mixing of the adhesive compounds can be accomplished in the still sealed capsule body by unfolding the neck and then alternate squeezing of each capsule, the mixed adhesive then being squeezed into one capsule. By cutting the neck of the capsule body (9, Figure 3), the adhesive can be applied to objects. Alternatively the sealed capsule is cut below the neck once the adhesives compounds have been mixed, and electrical wires 12, Figure 12 are inserted into the mixed adhesive contained in the capsule body, heat then being applied to the capsule body to shrink the capsule wall around the electrical wire conductors to connect them. The external surface of the capsule may be colour coded, the capsule being an integral unit of plastics material. <IMAGE>

Title: Shower Head
Inventor: LO MEI KAM
IPC: B05B1/16
Filed: 1994-11-04
Abstract: A multi-spray shower head comprises mist spray. When used with hot water this fine spray becomes steam. To prevent the user from scalding him- or herself immediately after using the mist spray with such hot water, the shower head includes a water operated safety pin assembly (60) which lock the shower head on the mist spray mode until the water pressure is reduced below a predetermined level. The mist spray is formed by passing water through mist channels (112) which have mist pins (114) which form spiralling water paths whereby water emerges from small diameter mist apertures (28) as a fine spray. Pulses may be provided by water-driven rotation of element (122). <IMAGE>
