Patent GB-843777-A (GB)
Abstract: 843,777. Feedwater heating; forced flow steam boilers. WALTHER & CIE A.G. July 2, 1956, No. 23659/59. Divided out of 843,776. Classes 64(1) and 123(2) [Also in Group XXVI]  In a steam turbine plant in which initial superheating and reheating of the live steam is effected by a heat carrier, the condensate is heated in the bled steam feed water heaters c and passed to the boiler feed pump d. It is then forced through the feed water preheater e into the boiler heating surfaces f. The steam then flows to the turbine. The heat carrier circulated by the pump i is heated in a preheater k and in contact heating surfaces m. The combustion air is heated in a high temperature heater q and a low temperature heater r. In a modification, Fig. 3 (not shown), the exhaust steam from the turbine is used first to heat the steam from the steam generator before it enters the initial superheater, then to heat part of the feed water leaving the boiler feed pump and finally to heat part of the feed water leaving.the condensate extraction pump which feed water is returned to the circuit at the boiler' feed pump suction.
Patent GB-2180232-A (GB)
Title: Optical fibre
Inventor: IRVEN JOHN
IPC: C03B37/018
Filed: 1985-09-13
Abstract: A method of manufacturing a rod preform from which polarisation maintaining optical fibre can be drawn, which method enables the achievement of stress anisotropy without geometrical asymmetry as in a conventional method. Following the formation of two orthogonal stripes of a stress cladding material in a substrate tube, a differential deposition process is employed first to fill the gaps between the stripes with inner cladding layer material and then to cover the filled gaps and exposed stripes with a uniform layer of inner cladding layer material. Core layers are subsequently deposited. During collapse of the substrate tube to a preform the asymmetric stress cladding causes stress anisotropy but without distorting the core layers as in the conventional method.

Title: Seat belt retracting device
Inventor: YOUNG KWON KYU
IPC: B60R22/44
Filed: 1987-08-14
Abstract: A seat belt retracting device, to be used in conjunction with seat belts which protect the occupants of vehicles, enables the tension in a seat belt 13 to be reduced once the belt 13 has been payed out to a required length and fastened. A meshing engagement of three gears 16, 19 and 23 controls the tension applied to the belt 13 by regulating the combined torque of two spiral springs 17 and 18, applied to a reel 11 around which the seat belt 13 is wound. A drum 26, in contact with the wound belt 13a, controls the engagement of gear 23 with gears 16 and 19, thereby determining the point at which the winding force exerted upon the belt 13 is to be increased as the belt 13 is retracted. <IMAGE>

Title: Densitometer
Inventor: BROWN NIGEL PEARSON
IPC: G01N23/12
Filed: 1987-11-11
Abstract: A scanning densitometer for measuring the density of a two-phase mixture in a pipe or container has a source 3 of radiation and a detector 4 which can be positioned on either side of the pipe or container and means 9 for moving the source and detector synchronously so that the radiation beam between the source and detector can pass through the two-phase mixture at different positions across the section of the pipe or container. The densitometer can thus measure the uniformity of density of a two-phase mixture in a pipe or container by passing a beam of radiation along a series of parallel chords, which can be horizontal, vertical or at any intermediate angle. The apparatus may be mounted on a pipe carrying coal slurry and comprise a radioactive X-ray source and a scintillation counter connected to move together by means of a bridge 8 pivoted at 7. <IMAGE>

Title: Nesting and stacking containers
Inventor: HOLLIDAY HUBERT JAMES
IPC: B65D21/04

Abstract: Opposed walls of a container each have, adjacent their base, an outwardly directed projection 9. The top of each wall has an outwardly cranked or directed portion 10 which continues into a further portion 11, the interior surface of which lies in a vertical plane which extends beyond the free end of the projection 9. The further portion 11 terminates in a platform 15 located immediately above the projection 9. If an identical container is lowered on to the container the projections 9 of the identical container engage the platforms 15 so that the containers are stacked. However, if an identical container is located beside the said container with the projections 9 at a level below the upper platform 15 but above the outwardly cranked portions 10 of the walls, the identical container can be moved into register with the first container and then lowered, the containers then being nested. <IMAGE>
