Patent GB-2137348-A (GB)
Title: Ultrasonic liquid interface detector
Inventor: SCOTT-KESTIN COLIN BASIL
IPC: G01F23/296
Filed: 1984-03-30
Abstract: A sensor for detecting an interface of a liquid in a container comprises a transmitter (14) and a receiver (20) of ultrasonic waves, each situated outside the container, and coupled to the wall of the container by a strip waveguide. The transmitter (14) is arranged to cause surface acoustic waves e.g. Lamb waves to propagate through a portion of the wall, and the receiver (20) is arranged to detect waves derived from the transmitter (14). When the liquid is adjacent to the portion of the wall, mode conversion of the surface acoustic waves in the wall of the vessel into compression waves in the liquid causes a reduction in the amplitude of waves reaching the receiver (20). The embodiment of Fig. 2 uses two or more transmitter-receiver sets spaced apart along the container wall and may determine whether the interface is below, between or above the sets from the ratio of the amplitudes of the received waves. The embodiment of Fig. 3 uses transducers that extend over the expected distance of variation of interface position. These transducers may comprise several individual transducers and may be coupled directly to the container wall. <IMAGE>

Title: Cobalt-containing catalyst activation
Inventor: POST MARTIN FRANCISUS MARIA
IPC: B01J23/86
Filed: 1985-07-19
Abstract: During the activation of Co/Zr/SiO2 catalysts by contacting them with a H2-containing gas at a temperature between 200 and 350 DEG C and a H2 partial pressure between 0.001 and 75 bar, the H2 partial pressure is gradually or stepwise increased from an initial value (PH2)I to an ultimate value (PH2)u in such a way that (PH2)u >/= 5 x (PH2)I. The time required for the activation can be drastically reduced (to about 10 hours or less) by carrying out the activation as described hereinbefore as a result of which catalysts with an improved activity and selectivity are obtained for the conversion of a mixture of CO and H2 into hydrocarbon.

Title: Apparatus for advancing a stage loader
Inventor: HURT FRANK
IPC: B62D57/00
Filed: 1985-09-20
Abstract: Apparatus for advancing a stage loader conveyor along a mine roadway comprises a base framework (10) and an upper framework (12) interconnected by a pair of hydraulic rams (14,16). Rollers (24) mounted on the upper framework (12) in an inclined arrangement locate in respective inclined tracks on the base framework (10). When the rams (14,16) are extended the upper framework (12) is propelled along the inclined tracks by means of the rollers (24). The resultant upwards force on the stage loader beam produces a reduction in frictional resistance between the upstream end of the stage loader and the roadway floor. The framework (10) is maintained by the loading of the stage loader and cannot move rearwardly. When the rams (14,16) are retracted, the base framework (10) is caused to advance so as to complete the advancement of the stage loader conveyor. <IMAGE>

Title: Disposable sample cassette for high pressure chromatography
Inventor: GOOD THOMAS J
IPC: G01N1/40
Filed: 1985-10-14
Abstract: A cassette-like holder of a plurality of sample columns 32 for an automatic injection unit which sequentially and successively advances the cassette and removes each sample therefrom in accordance with the test to be conducted on the sample. The cassette-like sample carrier utilizes a plurality of sample columns 32 disposed in line with each other, with the body of the cassette being unsymmetrical (flanges 40, 42, and ribs 46) to prevent reversal thereof in the injection machine. The injection machine, automatically advances the cassette to the first sample column, connects the column to the chromatographic system, removes the sample therefrom, decouples the sample tube from the system and again advances the cassette to the next sample tube for processing. The injection apparatus engages the cassette by biting into area 36 to sequentially provide positive sealing and support for each sample tube so that high pressures may be used without requiring the cassette to support such pressures and without requiring additional special seals. <IMAGE>

Title: Cut and folded article
Inventor: CROUCHER ANTONY HARRY
IPC: A42B1/04
Filed: 1985-11-08
Abstract: It has been found that the rate limiting step in manufacture of a forage cap is the insertion of a male tube end within a female tube end, which is presently done by hand. It would be preferable, for reasons both of economy and hygene to automate this step. The present invention provides a method for the insertion of a laminar element within a lay-flat tube to form a sliding interference fit, wherein at least one re-entrant tab (4), hinged at a forward edge thereof is formed at or toward the leading edge of the laminar element to provide a point upon which a tongue or other laminar structure can be brought to bear and thus facilitate automation of the insertion of the laminar element within the tube. The invention further extends to a lay-flat tube for formation into a hoop, wherein at least one re-entrant tab, hinged at a forward edge thereof is formed at or toward one end of the tube. Assembly of the paper hoop is facilitated if the grain of the paper forming the tube is substantially parallel to the axis of the tube. <IMAGE>

Title: Method of decontaminating soils
Inventor: FRANCK HEINZ-GERHARD
IPC: B09C1/06
Filed: 1986-12-12
Abstract: Soils which have been affected with high-boiling or not easily decomposable organic pollutants are decontaminated by direct flame treatment in a rotating drum. The temperature is in the range 600-1,200 DEG C. Catalytic inserts of copper, vanadium or molybdenum steel in the drum stir the soil. Combustion or decomposition of the pollutants may be promoted by alkali, alkaline earth oxides, hydroxides or carbonates or by magnesium, aluminium iron or zinc powders. Adjusting the stoichiometric ratio of oxygen to fuel promotes either complete combustion or splitting of the pollutants into low molecular fragments for recovery from the flue-gas.

Abstract: A method for testing integrated circuits provided on a carrier. The circuits include a series input (22) and a series output (24) for test and result patterns. A mode control register (30) receives a mode control signal train via the serial input. Under the control of said mode control signal train the serial input and output can be shortcircuited to each other, or further registers (32, 34, 36) can be selectively filled and emptied. In this manner, both the interior of the integrated circuit and respective interconnection functions can easily be tested by a universal protocol. Integrated circuits and the carrier only require minor extension/adaptations.

Title: Substance for the sorption of oil and related compounds spilled on water and other substrates
Inventor: JONES JAMES ALFRED
IPC: C02F1/68
Filed: 1987-10-26
Abstract: The invention relates to a substance produced, typically, from the cork of the cork-tree (Quercus Suber.) by subjecting it to physical and chemical treatment to render it oleophilic and hydrophobic. Such a substance is reduced in size to give it optimum sorption capacity. The substance is used either as a loose powder, or contained in an oil-permeable packaging in the shape of a pillow, sock or blanket. Oil is removed from the surface of water or other substrates by sorption on the substance and can be subsequently recovered by pressure or centrifugal force or by solvent extraction and/or distillation. Alternatively the oil can be incinerated or biodegraded in situ or after removal. Oil can also be recovered from sand and/or shale deposits using the substance.
