Title: A Method for the Correction of Unbalance Present in a Rotary Body
IPC: G01M1/30
Filed: 1979-05-22
Abstract: A method for the correction of unbalance present in a rotary body involves applying material to or removing material from a number of correction sites around the body, the correction sites being determined or limited by structural features of the body, for example as in rotors or armatures of electric motors. The measured unbalance for a given correction plane is analysed into a number of separate components corresponding to a maximum of half and a minimum of two of the correction sides, each component being equivalent to an integral number of standard unit weights. <IMAGE>

Title: A process for solidifying radioactive fission products
IPC: G21F9/16
Filed: 1979-07-17
Abstract: A highly radioactive fission product solution accumulated during the reprocessing of nuclear fuels is converted into a solid, non-crust-forming, free-flowing and pourable product by the addition of a surface-rich, capillary- active, glass-forming inorganic carrier substance so that the solid product can in turn be converted into a permanently storable form by embedding in a glass mass or other material. The surface- fich, capillary-active, glass-forming substance may be silicon dioxide, aluminium silicate and/or aluminium oxide, preferably in the form of a free-flowing and pourable, evenly formed granulate having a grain size of from 1 to 5 mm.
Patent GB-2058363-A (GB)
Title: A Method of Wiring Including Checking the Accurate Location of Individual Wires in a Wiring Layout
IPC: G01R31/04
Filed: 1979-08-31
Abstract: In assembling a wiring harness, a number of wires 2a, 2b, 2c etc. are laid into recesses in supports 3a, 3b, 3c, etc. The supports carry projecting spikes 8 (Figure 2) which are inserted into a harness board 1 at the respective desired location of connection of the wires 2a, 2b, 2c etc. in the wiring layout. By means of the supports 3a, 3b, 3c etc., the wires 2a, 2b, 2c etc. are conductively, inductively or capacitively coupled to the connection points which are connected by a ribbon or other wire 4 to a monitoring device 5. As assembly of the wires 2a, 2b, 2c etc. and the supports 2a, 3b, 3c etc. progresses, the sequence of electrical signals is sensed by the device 5 which issues a warning if the sensed sequence differs from a predetermined, desired sequence stored in the device 5. When these sequences correspond without error, the wires 2a, 2b, 2c etc. are removed from the supports 3a, 3b, 3c, etc. and permanently connected to the connection points on the wiring layout. <IMAGE>
Patent GB-2072006-A (GB)
Title: Roller and sliding system for applying flexible covers
IPC: E04H4/10
Filed: 1980-03-20
Abstract: A cover system for pools etc comprises roller tracks attached to two sides of the area to be covered, the tracks being fixed parallel to each other and to the top of the surround. A series of twin wheeled roller carriers is inserted into the tracks on each side and each roller carrier is attached to its opposite number by a rod or strap and also to an adjacent carrier by a strap of predetermined length. When the front pair of rollers is pulled along the tracks, a pair of roller carriers will follow at measured intervals dictated by the strap length. The flexible cover is attached to the front pair of roller carriers which, when pulled, cause the cover to follow, suspended by the framework of rods etc underneath. Thus the cover is supported at all times with most of its weight carried by the supporting framework and roller carriers. The edges of the cover are therefore unstressed and are trained to run inside a groove on the tracks to form a seal against dirt and debris and to provide security and safety in the case of swimming pools. The system may alternatively be used to secure a tarpaulin on open-top or open-sided container vehicles. <IMAGE>

Title: Minus-curve toric lens generator
IPC: B24B13/00
Filed: 1980-04-03
Abstract: A minus-curve toric lens generator has a mount (28) for a lens grinding, lapping or polishing tool (40) and a support (18) for a lens (107) or lens holder (106). The tool mount (28) and lens support (18) are so constructed and arranged that, when the generator is in use, the support is moved about a pivot 57 and a working zone of the tool (40) traces a line which is swept across the surface being ground, lapped or polished. The line lies in a plane or successive planes which are substantially perpendicular to that surface throughout the sweep. The lens support may be indexed through 180 DEG so that one half of the lens is machined and then, after indexing, the other half. The tool may be a point cutter moved to sweep in an arc across the lens, the arc being, in turn, swept across the lens. <IMAGE>

Title: Inclinometer
IPC: G01C9/12
Filed: 1980-04-18
Abstract: An inclinometer has a body 1 adjustably mounted to a cylindrical fluid-filled member 2. A pointer 4 is mounted on a shaft located on the axis of the member 2 and has a float 4a and pointer 4b arranged to traverse a circular scale 5. The scale 5 may be calibrated in degrees and/or percentage values from a true horizontal or true vertical position. The instrument operates by upthrust of the fluid on the float 4a to maintain the pointer 4b in a true vertical position. So as to compensate for pressure changes within the fluid, the member 2 and/or the pointer 4 may be formed of an elastically deformable material. <IMAGE>

Patent GB-2087250-A (GB)
Title: Catalyst preparation
IPC: B01J37/02
Filed: 1978-10-23
Abstract: The invention is concerned with providing substrates with coatings obtainable from sols, for example to protect the substrate (such as in nuclear reactors or hydrocarbon cracking plant) or to provide a carrier for catalytically active material. Hitherto, coatings obtained from sols have had a high porosity and high surface area so that they have not been entirely satisfactory for the above applications. In the invention, dense, low-porosity coatings are provided by contacting the substrate with a sol of refractory material (e.g. CeO2 or SiO2) convertible to a gel of density at least 40% of the theoretical density of the refractory material, and converting the sol to the gel. Optionally, the gel may be converted to a ceramic coating by firing.

Title: Pressure differential indicator
IPC: G01L9/14
Filed: 1982-05-17
Abstract: A brightly coloured signal body 20 having a ferrous part 22 is restrained against the forces of a spring 21 within a housing by a permanent magnet 10 carried by a piston 8. The signal body 20 and piston 8 are physically separated by a relatively thin wall, and opposite ends of the piston 8 are exposed to fluid pressures from two locations, e.g., at the input and output sides of a filter. The piston 8 is urged toward the signal body 20 by a second spring 15. When the pressure difference across the piston 8 is great enough the piston 8 moves away from the body 20, taking the magnet and letting the first spring 21 push the body 20 to an obvious protruding position. The piston carries a valve member 16 which closes passage 7 when excess pressure occurs thereby preventing contaminated fluid passing to the low pressure side via channel 12. <IMAGE>

Abstract: A cable-handler system for use with a face conveyor and a coal cutting machine 10 comprises a line 16 which conveys power to the machine 10 and which is connected at one end to a fixed point 17 and at its opposite end 18 to a machine 10. A line-storage trough extends alongside the conveyor and a line guide 21 engages with the cable 16 and moves along the trough to guide the insertion into, or removal from, the trough of portions of the cable 16. Relative movement of the machine 10 in a direction away from the fixed point 17 is accompanied by movement of the guide 21 in the same direction and by guidance of the cable 16 into the storage trough and relative movement of the machine 10 in a direction towards the point 17 is accompanied by movement of the guide 21 in the same direction and by progressive withdrawal of the cable 16 from the storage trough. Preferably, the line guide comprises a pulley block 21 which is drawn along the line storage trough in a direction away from the fixed point 17 by a haulage cable 20, and in the opposite direction by the cable 16. <IMAGE>
