Title: Method for improving the strength and impermeability of soils and engineering structures
Inventor: CSANDA FERENC
IPC: C09K17/46
Filed: 1985-04-22
Abstract: Method for improving the strength and impermeability of soils and engineering structures by forming a hydrogel composed of silicic acid and a cross-linked swellable organic polymer in or on the soil or structure treated. According to the invention an aqueous solution of a silicic acid gel precursor is contacted with a water-soluble gel-forming vinyl monomer in the presence of a redox polymerization catalyst system; a cross-linking agent for the polymer obtained; an organic polycarboxylic acid; optionally an additive which modifies the structure of the gel formed and optionally a filling agent. By the method of the invention a homogeneous, stable, strong and elastic gel is obtained.

Title: A method for manufacturing a semiconductor device having a layered structure
Inventor: JOYCE BRUCE ARTHUR
IPC: H01L21/20
Filed: 1987-04-06
Abstract: A method of manufacturing a semiconductor device is described in which gaseous material is supplied into a reaction chamber containing a substrate to cause a first epitaxial layer of a first material to grow on the substrate and switching means are then operated to alter within a predetermined period the supply of gaseous material into the reaction chamber to cause a second eitaxial layer of a second material to grow on the first layer. During the predetermined period a radiant heat source is activated to radiantly heat the surface of the first layer so as to smooth the first layer on an atomic level before growth of the second layer is commenced. The radiant heat source may be a laser capable of directing one or more laser pulses at the surface to be radiantly heated.

Title: Hydropneumatic suspension for motor vehicles
Inventor: KNECHT HEINZ
IPC: F16F9/50
Filed: 1987-09-09
Abstract: In a hydropneumatic suspension system for motor vehicles at least two telescopic spring strut cylinders (1) are arranged in the region of the vehicle wheels between the vehicle structure and the axle, and each cylinder is connected through a pressure fluid pipe (16) to a pressure accumulator (7) and is divided into two working chambers (4) and (5) by a damping piston (3) secured on a piston rod (2). In order to achieve an additional influence on the damping force through the pressure fluid pipe (16) and at the same time maintain a positive coupling relationship under all operating conditions, in particular on rapid outward movement of the piston rod (2) (extension stroke), the cross-sectional area for flow in the pressure fluid pipe is influenced by a damping element (8) and a valve (9) is arranged in a bypass (17) in parallel to the damping element. The valve comprises a valve closure surface which is engageable with a seating (15) which is exposed to the pressure of the accumulator (7). The valve closure surface is arranged to be displaced off the valve seating (15) so as to open the bypass when the pressure in the working chamber (4) falls below a predetermined value. The damping element (8) and valve (9) can be combined in a single component (Fig. 6). <IMAGE>

Title: Envelope and form assemblies
Inventor: JEFFERSON THOMAS FREDERICK
IPC: B42D5/02
Filed: 1987-11-04
Abstract: A combined form set and envelope therefor includes a front sheet (12), a back sheet (13) and a plurality of intermediate sheets (14a, 14b, 14c). The front and back sheets are secured directly together along one pair of opposite edges and all the sheets are adhesively joined together along the other pair of opposite edges. Adjacent one of these edges, each of the sheets is perforated to form a tear-off stub allowing access to the intermediate sheets. The lines of perforation are progressively closer to this edge from the front intermediate sheet to the back sheet, thereby exposing each intermediate sheet to view for individual extraction once the stub has been torn off. <IMAGE>

Title: Improvements in or relating to the control of articles
Inventor: WIGNALL DAVID
IPC: B65G7/00
Filed: 1988-05-11
Abstract: Barrels are lowered into a cellar by rolling the barrels over the top edge of a wall 12. The barrels fall part of the way down the passage until they jam between the opposed surfaces of a gate 22 and a ladder 16 whereupon their rate of descent is checked, and the barrels then move slowly downwards as the ladder 16 pivots in the clockwise direction about hinges 18 against the action of a spring 26 and an associated damper 28. The barrels continue to move downwards gradually until they reach the lower opening 20 whereupon they either roll slowly out of the opening or are removed manually through the opening. The barrels may be hauled back up the ladder by a winch attached to a platform (30, Fig 2, not shown). In a further embodiment (Figs 3, 4, not shown), a pivotally-mounted retarder (42) near the bottom of a fixed ladder-like structure can be held in different intermediate positions. <IMAGE>

Patent GB-917641-A (GB)
IPC: G03G5/14
Abstract: 917,641. Electrophotographically produced printing plates. KALLE A.G. Dec. 20, 1960 [Dec. 29, 1959], No. 43764/60. Class 98 (2) [Also in Groups III and XXXVI] An electrophotographic printing plate is made by coating a conducting support first with an alkali-soluble resin and then with an alkalisoluble organic photo-conductor, charging the coating, exposing to form a latent image, developing and fixing the image, and dissolving away the image-free parts of the resin and photo-conductive layers by treatment with an alkaline liquid. If the developer contains two oppositely-charged toners, the one of opposite polarity to the image must be alkali-insoluble while the other must be alkali-soluble. The fixed image may be lacquered before treatment with the alkali, as the latter will remove the lacquer from the image-free areas. The alkaline liquid may be an alkali or alkaline earth metal hydroxide, an alkali metal phosphate, sodium metasilicate, an organic amine or polyamine, an amino-alcohol or a substituted lower acid amide. These may be used in solution in water or an oxygenated organic solvent, or the organic bases can be undiluted. A macromolecular thickening agent may be added. The hydrophilic properties of the plate can be increased by after-treatment with an acid such as phosphoric, or by incorporating a silicate in the alkaline liquid. The support may be metal (e.g. aluminium, copper, brass, zinc), paper, regenerated cellulose, polyvinyl alcohol, polyamide, polyurethane, cellulose ester, polyester, polycarbonate or polyolefine, rendered conductive, if necessary, by coating or impregnation. The resin is preferably one containing carboxylic, sulphonic or sulphonamide groups, and may be of the polyvinyl, maleic, alkyd, styrenemaleic or colophony type.
