Patent GB-2122512-A (GB)
Title: Thermally isolated developer pump
Inventor: FAUCHER JEROME
IPC: G03G15/10
Filed: 1981-11-18
Abstract: In the liquid developing system (24) for an electrostatic copier (10), the liquid developer (26) is ordinarily pumped to the developer electrode (30) through a conduit (86) from a storage tank (28). Generally, the motor (50) for the liquid pump housing (82) is located in the storage tank (28) above the level of the liquid developer, with motor shafts extending down into the developer to the pump housing. In this type of arrangement, the heat generated by the pump motor (50) is transferred to the liquid developer thereby raising the temperature of the developer to the point that it produces an undesirable "halo" effect on the developed image. In order to eliminate this "halo" effect, the heat generating pump motor (50) of the present device is thermally isolated from the liquid developer tank (28) for the electrostatic copier. In one embodiment, the pump impeller (90), with a first magnet (92) fixed to it, is magnetically coupled to a second magnet (70) disposed outside the tank. In this embodiment, the second magnet (70) is coupled to a pulley (72) driven by a belt (94) which is coupled to the remote motor (50) by pulley (62). In another embodiment, the second magnet (130) is mounted on the motor shaft.

Title: Distributed sensors
Inventor: HANDEREK VINCENT ANDREI
IPC: G02B6/036
Filed: 1982-08-03
Abstract: An optical fibre sensor cable includes two closely-spaced waveguides each adapted to support a responsive mode. At intervals along its length the cable is adapted to provide sensing elements at which coupling between the modes can be achieved. In the case of a coaxial structure a rod guide (1) with cladding (3) is surrounded by a coaxial tube guide (2) having external cladding (4). At the sensing elements the external cladding (4) is of a refractive index which is variable in dependence on a perturbation to be sensed at the sensing element, for example pressure, and which is such as to permit optical power launched into one guide to be coupled to the other guide with a power distribution dependent on the perturbation. If each sensing element is such as to permit coupling at a different optical frequency then the sensing elements can be spatially resolved along the length of the cable. <IMAGE>

Title: Milk sampling device
Inventor: MILLAR THOMAS DOUGLAS
IPC: G01N1/20
Filed: 1982-09-14
Abstract: A milk sampling device for a milking machine is fitted in a milk tube between a set of teat cups and a milk line of the milking machine. The device includes a passageway 4 through which air and entrained milk pass, and a chamber 5 of larger volume than the passageway and milk tube. The chamber 5 is connected to the passageway 4 by means of an orifice, which can be sealed by valve member 8, a conduit 6 and a chamber 7. A sampling vessel 22 is connected to chamber 5 by means of a tapered rubber sleeve 21. The pulsating flow of milk and air causes variations of pressure as between the passageway and the chamber resulting in a lower pressure in the chamber which draws a sample of milk into this chamber and thence into the sampling vessel. <IMAGE>

Title: Balancing of interferometric optical fibre sensors
Inventor: EPWORTH RICHARD EDWARD
IPC: G01H9/00
Filed: 1983-10-05
Abstract: An interferometric sensor system able to null automatically the path difference between the sensor and reference fibre paths (2,3). A low level modulation (6) is applied to the laser drive current at frequency f1 to provide source intensity and wavelength modulation. The (piezo electric) fibre stretcher (5) is fed with two signals, one of which dithers the path difference at a relatively lower frequency f2, over a range of path difference of say half a wavelength. At the half peak intensity points on either side of the fringe, the intensity of the fluctuation at f1 is measured. These are compared (9) to identify the sign of the path difference between the arms, and an error signal is fed back to the fibre stretcher to balance the path differences. <IMAGE>

Title: Navigation system and method
Inventor: JOHANNESSEN ROLF
IPC: G01S5/10
Filed: 1985-09-13
Abstract: A mobile receiver determines its position from received hyperbolic terrestrial navigation system signals (e.g. Loran-C) and geostationary earth satellite signals, the latter being spectrum spread with a chipping code time locked to a standard such as the Loran-C signals, by time comparing the chipping code with the Loran-C signals. in the case of two Loran-C transmitters and one satellite the mobile receiver determines one line of position from the time comparison and another line of position from the received Loran-C signals assumption being made to the effect that the receiver is on the earth's surface. Integrating a terrestrial navigation system e.g. Loran-C with satellite signals in this manner effectively enhances the range of Loran-C without requiring high peak power pulses from the satellite. <IMAGE>

Inventor: DOI NOBUYOSHI
IPC: G05D7/01
Filed: 1985-10-08
Abstract: A branch valve for a toilet bowl with a showering nozzle has an inlet (18) communicating with a water source, outlets (12, 14) communicating with a water tank for flushing a toilet bowl and with the showering nozzle for a showering operation respectively, and a branch chamber formed within a valve casing (17) of the branch valve (11) which enables the inlet (18) and the outlets (12, 14) to communicate with each other therein.

Title: Sealant delivery system
Inventor: CLARK JOHN ROBERT GEORGE
IPC: B05B15/20
Filed: 1986-08-12
Abstract: A sealant delivery system has a reservoir (7) for air or other oxygen- containing gas, which is connected to a vessel (1) containing an anaerobic sealant (10). When the air is passed through valve (6) to a pipe (9) extending into the sealant (10), curing of the sealant (10) is inhibited, by the action of the air passing through the sealant (10). Furthermore, the air establishes a top-pressure in the vessel (1), forcing the sealant (10) from the outlet (2) and through a conduit (3) to an object to be sealed. In this way, curing of the sealant (10) before it reaches the object may be prevented. <IMAGE>
