Title: Detecting Faults in Buried Cables
IPC: G01R31/08
Filed: 1980-08-12
Abstract: A signal of a predetermined frequency is injected into the served (insulated) sheath of an underground cable and the resultant magnetic @ field generated is monitored using two pick-up coils 62 and 63 aligned along the length of the cable. The phase difference between the emfs induced in the two coils is a measure of the @ field gradient and a sharp change in phase accompanied by a change in emf. magnitude indicates a fault. The same two coils turned through 90 DEG transversely to the cable can be used to locate the cable by scanning transversely to the cable. As the coils pass over the cable the relative phase of the induced emf signals in the coils reverses. Alternatively, three or four coils may be used arranged in two orthogonal pairs with the coils of one pair being aligned in use along the cable and the coils of the other pair transverse to the cable. <IMAGE>

Title: Solid Electrolyte Oxygen- sensing Element of Laminated Structure
IPC: G01N27/416
Filed: 1980-12-08
Abstract: An oxygen sensing element (10) for use in a device to detect oxygen concentration in a gas atmosphere or to detect air/fuel ratio in an internal combustion engine based on the oxygen concentration in the exhaust gas. The element is a lamination of generally flat and relatively thin layers including a shield layer (12) of a ceramic material, first solid electrolyte layer (14), inner electrode layer (16), second solid electrolyte layer (18) and outer electrode layer (20) laid one upon another in the mentioned order. The second solid electrolyte layer (18) and the two electrode layers (16, 20) constitute a concentration cell. The first solid electrolyte layer (14) is formed of essentially the same material as the second solid electrolyte layer (18), so that there is no or little difference in thermal expansion coefficient between the two layers (14, 18) which tightly sandwich the inner electrode layer (16) therebetween. Hence, the inner electrode layer (16) does not tend to separate from either of the two solid electrolyte layers (14, 18) even when the element (10) is subjected to great and repeated changes in temperature.

Title: Solar water heater
IPC: F24S23/77
Filed: 1981-02-10
Abstract: A solar water heater comprises a box 1 blackened on the inside and having a window 2. Inside the box a plano-convex lens 6 is formed by passing water to be heated along a trough made up of a sheet 3 of flexible transparent plastics material. Sun's rays 7 enter the box via a pivotable mirror and window 2 and are converged to a focus by means of the lens 6. A blackened pipe 8 is connected to receive water leaving the trough, said pipe being arranged coincident with the focus to receive heat resulting from the focussing of the sun's rays. A mirror may be used to reflect the convergent beam so that the focus lies immediately beneath the lens, and not far below as would otherwise be the case. Water passing through the heater is heated in three ways: firstly in the reservoir due to passage of the sun's rays therethrough, secondly in the heat exchanger pipe 8 due to concentration of the sun's rays at the focus of the lens, and thirdly in the reservoir and heat exchanger due to straightforward conduction from the air in the box whose temperature is maintained at a high level due to the "greenhouse" effect. <IMAGE>
Patent GB-2073129-A (GB)
Title: Coin Wrapping Paper
IPC: B65D85/58
Filed: 1981-03-06
Abstract: Stacked coins are wrapped with a predetermined length of wrapping paper to form a bundle of wrapped coins. The wrapping paper is in the form of a strip having transverse rows of perforations b. The longitudinal distance L between two adjacent rows B is predetermined so that it is equal to the circumference of the coins to be wrapped. Hence when the wrapping paper A is wound around the stacked coins, two rows B of perforations b are superimposed one on another. Furthermore, no perforation is provided on the opposite edge portions 4, 5 of the wrapping paper A to be crimped about the ends of the stack of coins. Consequently, when the bundle of wrapped coins is twisted by hands at opposite ends, it is opened along the rows 18 of perforations b except for the crimped portions, so as to provide access to the individual coins for taking them out of the opened bundle. <IMAGE>

Title: Hydraulic seal for pit prop
Inventor: LITHERLAND JAMES ALBERT FRAZIE
IPC: F16J15/32
Filed: 1982-07-20
Abstract: An elastomeric seal (1), particularly for mining roof supports, has a circumferentially extending primary sealing ridge (4) for sealing against the cylinder wall at both low and high pressure differentials. In order to provide lubrication of the primary sealing ridge, a series of fluid reservoirs (10) are defined adjacent to opposite sides of the primary sealing ridge by a respective web (5) of secondary sealing ridges, each web consisting of a circumferential ridge (6) and a series of axial ridges (7). The secondary ridges (6, 7) are dimensioned such that at low fluid pressure differentials across the piston there is a radial clearance between the secondary ridges and the cylinder wall, to reduce seal friction at low pressures, but at high pressure differentials the portion of the seal adjacent to the low pressure chamber is elastomerically deformed to bring the web of secondary ridges at that end into sealing engagement with the cylinder walls, to provide a secondary seal and to trap fluid in the reservoirs. The seal may be arranged to be single- acting or double-acting. <IMAGE>

Title: Supported heterogeneous catalyst and process for its manufacture
Inventor: MOSKOVITS MARTIN
IPC: C10G49/04
Filed: 1982-12-17
Abstract: Catalysts for use in promoting heterogeneous chemical reactions, such as hydrogenation, cracking, dehydrogenation and Fischer-Tropsch reactions, are prepared by depositing a catalytically active metal such as nickel onto an anodized aluminum substrate in such a manner that the metal particles are deposited in micro- particulate form to enhance their catalytic activity. The aluminum substrate is prepared by cleaning and anodizing it, so as to deposit thereon an aluminum oxide surface film having micro porosity. Then the substrate is immersed into an electrolysis bath of solution of salt of the metal to be deposited, and subjected to alternating current electrolysis to cause the required deposition. Prior to use, the catalysts so prepared should be heated to remove absorbed gases from their porous surfaces.
