Title: Getter trap for removing hydrogen and oxygen from a liquid metal
Inventor: GRUNDY BRIAN ROYLE
IPC: B01J23/94
Filed: 1988-10-05
Abstract: A getter trap (1) to remove hydrogen and oxygen from a liquid metal, such as liquid sodium, includes an elongated, closed housing (3) having an inlet (5) at one end thereof and an outlet (7) at the other end. A getter material (9) is randomly disposed within the housing (3) and comprises a zirconium-containing substrate of hollow, tubular sections (11) having a coating (17) thereon of a gettering alloy of zirconium, vanadium and iron. As a liquid metal flows through the inlet (5) into the housing (3) through the getter material (9), and is discharged from the housing (3) through the outlet (7), hydrogen and oxygen impurities are removed from the liquid metal. The getter trap (1) is particularly useful in an improved liquid metal cooled nuclear reactor system (39). <IMAGE>

Title: Litter/leaves collecting device
Inventor: COCKING DAVID WILKINSON
IPC: E01H12/00
Filed: 1988-11-08
Abstract: A device for collecting litter and leaves from substrates comprises a drum 2 having an array of spikes 12 extending radially from the peripheral surface thereof. The drum is rotatably mounted in a frame 4 which also supports a comb 8 with tooth 10 which are laid tangentially against the drum surface between the spikes. The spikes 12 are arranged on the drum surface such that the drum 2 can rotate with the comb teeth 10 at the base of the spikes. In use, the drum 2 is rolled across a substrate such that the spikes 12 pierce the substrate and material deposited thereon and lift such material from the substrate. The orientation of the comb 8 is such that the teeth 10 strip such material from the spikes 12 and carry it away to a receptacle 14 also mounted in the frame. The spikes 12 may be mounted directly on the drum 2 or on a belt which extends around two or more such drums. The drum or drums may themselves support the frame on a substrate. Alternatively the frame may be self-supporting with the spacing between the spikes and the substrate adjustable thereon. <IMAGE>

Title: Magnetostriction type torque sensor with feature of temperature dependent error compensation
Inventor: MIZUNO MASASHI
IPC: G01L3/10
Filed: 1988-12-23
Abstract: Detector coils L1-4 spaced axially along a shaft 1 are so designed and arranged as to compensate influence of temperature, particularly the error caused by an axial temperature gradient in the shaft. At least one coil (L2) is adjacent a magnetic anisotropy section (4) formed in the shaft 1. Each coil establishes a magnetic loop extending through the shaft 1 for monitoring the magnitude of any magnetostriction caused by torsional deformation of the shaft due to rotational torque, each coil producing output signals including a temperature dependent noise component. The noise components are removed, and the rotational torque is derived on the basis of the output signals without the noise components. Numerous coil configurations and connections, e.g. feeding differential amplifiers or in bridge circuits. are described.

Title: A security document with a warning pattern and a method for the preparation thereof
Inventor: GRONHOLM ERKKI
IPC: G07D7/00
Filed: 1989-03-23
Abstract: The invention relates to a security arrangement for a printed product, a security, a document, or the like, which prevents the precise copying of the original product by identifying the copy as non-authentic, and which comprises a protective area 4, 11 and a warning word 1, 10, each printed with a specific line technique which is parallel in relation to the other such that the warning word in the original product is not distinguishable from the protective area to the unaided eye, but that the properties of a copying machine or a scanner cause the protective area and the warning word to copy in ways different from each other, whereby a difference in the degree of blackness or in tone is produced between them, bringing out the warning word in the copy. Furthermore, the invention relates to a method for producing the line pattern of the protective area and the line pattern of the warning word described above and for combining these line patterns into one line pattern image so that, at the outline between the protective area and the letters of the warning word, there is formed according to a specific line technique a transition area 12, where the higher-frequency and the lower-frequency line rulings interlock and where the density range gradually changes. <IMAGE>

IPC: F24C3/12
Filed: 1989-10-18
Abstract: In a gas fire of the kind incorporating radiant units 3 heatable by flames from a gas burner to produce a source of radiant heat, which heat is supplemented by passing the products of combustion through a heat exchanger 6 which is used to heat further air drawn through the fire by convection, a damper 11 is coupled to openable and closable doors 9 in front of the fire, in such a way as to cause the damper to open on opening of the doors and to close partially on closure of the doors. This results in safer operation of the fire and also increases the thermal efficiency of the fire with the doors closed. With just one of the two doors open, the damper 11 is intermediate the open and partially closed positions. <IMAGE>
