Title: Chiral liquid crystal lamina with distinct regions
Inventor: DOBRUSSKIN CHRISTOPH
IPC: B44F1/14
Filed: 1993-09-22
Abstract: A chiral liquid crystal lamina comprises a region (6) in which the liquid crystal molecules are oriented such that the region is reflective to light in a given state of circular polarization in a given wavelength band, and a further region (5) in which the molecules are in a differently oriented or disordered or decomposed state such that the further region is not selectively reflective to light in a given state of circular polarization. A material may be made using a plurality of such laminae and a light transmissive medium with or without additional binders or pigments. This material may, for example, be used for security marking objects or decorative purposes, eg for packaging or for use as a cosmetic. <IMAGE>
Patent GB-2283361-A (GB)
Title: Refrigeration and electrical power generation
Inventor: ASPDEN HAROLD
IPC: H01L35/00
Filed: 1993-10-12
Abstract: The thermoelectric device disclosed in GB Patent No. 2,227,881 is developed by this invention to accentuate the Nernst Effect contribution. By using thin ferromagnetic metal laminations 1 of thickness commensurate with or smaller than the magnetic domain size (100 micron) and feeding current transversely through the laminations with heat flow in the laminar planes, the current, regardless of polarity, selects a passage through the lamination which traverses a magnetic domain polarization having a direction in which the Nernst EMF assists the current. This results in a conversion of heat into electricity. A superconducting polymer, oxidised polypropylene, may be used as a heat resistant filler between the laminations to provide the continuity for transverse current flow. Heat sinks 2 are insulated by coatings 3 and connections are made by conductors 4. <IMAGE>

Title: Spherulitic nitroguanidine
Inventor: THIEL KLAUS-DIETER
IPC: C07C277/08
Filed: 1994-09-28
Abstract: In the preparation of spherulitic nitroguanidine of high poured (bulk) and tapped density, nitroguanidine is brought into solution in dipolar aprotic solvents, e.g. DMF, DMSO, NMP or the like, by heating to above the saturation temperature ts and the supersaturated solution is cooled under a controlled temperature gradient ( DEG C/min), with crystal formation being aided by addition of particulate, spherulitic material. To obtain spherical nitroguanidine in high yield in a continuous process with reuse of the mother liquor, regularly spherical control particles having a diameter of from 5 to 500  mu m are added in an amount of from 0.05 to 5.00 % by mass to the solution while heating to above the saturation temperature ts, with the particle size being selected in such a way that, depending on the solution behaviour of the nitroguanidine used and its concentration, spherical control particles continue to be present in the specified amount in the supersaturated solution when the temperature drops below the saturation temperature.

The jaws (6a, 6b, 6c) each have screwthread engagement with an outer body (8). Rotation of the outer body (8) relative to the inner body causes the jaws to move. The surface of the outer body (8) is formed with three "flats" (14a, 14b, 14c) to aid grip of the chuck (2). This arrangement is particularly beneficial with spindle - locked drill/drivers.
Patent GB-2302818-A (GB)
Title: Rotating drum suction filter
Inventor: VIALS MICHAEL JOHN
IPC: B01D33/073
Filed: 1995-06-30
Abstract: A rotating drum filter 10, including replacable filter media 9 wrapped and sealed about the circumference, is partially submersed in dirty liquid 12. The filter supply pump 1 suction pipe 8, passes through otherwise solid end walls 7 via integral openings 5, to the clean liquid within the drum. The integral openings 5, also form the journal on which the drum rotates. Drawing off the filtered liquid increases the flow through the filter. A portion of the filtered flow is returned under pressure to backflush 6 the media. Additionally and where only part of the total flow is required filtered, the assembly can be arranged to filter less than the total flowrate and the excess bypassed over weirs 20 then returning to the main volume.

Patent GB-2299140-A (GB)
Title: Differential gearing preventing gear misalignment
Inventor: ISHIZUKA MAKOTO
IPC: F16H48/285
Filed: 1996-03-04
Abstract: A differential casing contains a pair of helical side gears 37, 39, as well as a pair of helical pinion gears 67, 69 accommodated in bores formed in the casing. When it is expected that the helix angle of the tooth trace of a helical pinion gear (e.g. 69) would be decreased by forward driving, the helical pinion gear is formed in advance so that the tooth depth gradually decreases from axial ends of the helical pinion gear toward the axial intermediate portion. Conversely, when it is expected that the helix angle would be increased by forward driving, the tooth depth gradually increases from the axial ends toward the axial intermediate portion. Alternatively, there may be a chamfered portion on the pinion gear. By these means, even if the helical pinion gear becomes slanted, it can be maintained in uniform contact with the bore over the whole tooth width, so that it is possible to prevent occurrence of eccentric abrasion and seizure.

The unit ( 211, Fig 6 ) has a second thickness less than the first thickness so that, when forced against the eye sockets of the wearer, flexing occurs.
Patent GB-2313189-A (GB)
Title: Pyrometer
Inventor: TAYLOR JOHN
IPC: G01J5/00
Filed: 1996-05-17
Abstract: A pyrometer arrangement for monitoring a temperature profile of a hot body eg a turbine blade (B) includes a point light source S which is arranged to transmit light through a window behind which the optical system, eg mirror M1 and lens L, is enclosed. Light reflected back through this window by a mirror M2 is detected by a photodetector D1 which generates a correction signal which compensates for changes in the transmissivity of the window due, e.g. to deposition of combustion products. To measure the temperature profile of a hot body of unknown temperature, the above optical system, excluding the mirror M2 can be advanced i.e. moved to the left to cause radiation-collecting mirror M1 to protrude from the casing C. In this mode the apparatus focuses incident radiation from the hot body onto the detector D1.

Patent GB-2302116-A (GB)
Title: Moling apparatus
Inventor: RODGER ALBERT ALEXANDER
IPC: E21B7/24
Filed: 1995-04-21
Abstract: A moling apparatus (2) comprises a housing (4) having a head (8) for penetrating ground, an anvil (16) disposed in the housing connected to the head, a hammer (18) disposed in the housing and spaced therefrom by resilient restraint means (20). A vibrator unit (42) is spaced from the hammer and arranged to transfer vibration to the housing and the hammer. In a first mode of the apparatus, vibration transmitted to the housing causes fluidization of the surrounding ground to allow progressive penetration of the apparatus. In a second mode, the braking effect of the ground on the head causes the hammer to move against the resilient means and impact the anvil thereby driving the head through the ground, said apparatus being operable at or between said modes.

IPC: E21B34/10
Filed: 1998-03-13
Abstract: A control system (50) is provided for controlling the flow of hydrocarbons out of a production well. The control system has a primary control circuit which is wholly hydraulic and a secondary control circuit which is wholly electrical. Hydraulic (64) and electrical (66) actuators associated respectively with the primary and secondary control circuits control the operation of chokes (60 and 62) located in the well. The downhole device controlled by the control system is switched from the primary circuit to the secondary circuit in the event of a failure occuring which prevents normal operation of the device by the primary circuit. The switching may be as a result of considerations other than failure such as a matter of choice by an operator or automated control system.
