Title: Method and arrangement for producing lagging mats for mine support
Inventor: DICK JOACHIM DIPL ING
IPC: B21F27/12
Filed: 1987-09-16
Abstract: A method of producing lagging mats for mine support from a wire grid with welded cross bars and longitudinal bars, a glassfibre fabric being arranged between the cross bars and the longitudinal bars. Before being put on the cross bars, this glassfibre fabric is perforated in the areas of the intersections to be subsequently formed by the cross bars and longitudinal bars while forming fabric-free welding areas and thus does not subsequently get in the way of the welding operation so that a sound welded joint is obtained between the cross bars and the longitudinal bars, even though the glassfibre fabric is an insulator. <IMAGE>

Abstract: Active matrix addressed liquid crystal TV sets configurated in the way described by A.G. Fischer in US-Pat. 3,840,695 can be enlarged to monolithic square-meter-sized wall TV panels. The large-area thin-film-electronic matrix circuit needed to address the superimposed liquid crystal layer can be vacuum-deposited from a multiple source evaporator onto one coherent glass pane through a number of exchanged small reticulated perforated sheet metal masks which are held successively against a chosen reticle of the large glass pane, in exact registration with each other and neighbouring reticles. The large glass pane must be precision-shifted in X-Y-reticle-steps for repeated vacuum depositions, in exact registration. The novel machinery required is described.

Patent DE-3738952-A1 (DE)
IPC: A01G9/02
Filed: 1987-11-17
Abstract: Cross-section of plant troughs (1) for use on the tables in greenhouses is in general U-shaped, which plant troughs may dependent on the method used for watering the plants either be open at the ends so that water can run off the troughs (1), or they may have end walls (6) so that water will remain in the troughs (1). Hitherto such end walls have been produced separately out of metal or plastics and subsequently glued onto the troughs. This is a costly method whereas the method and apparatus according to the invention point towards a plant trough (1) where the end walls (6) are produced as an integral part of the plant trough (1), by folding the utmost part of the trough upwards into the end walls (6) which are watertight and remain connected to the trough walls throughout the entire life-time of the plant trough.

Title: Levelling wheel for portable drilling machines
Inventor: KNOCH ROLF
IPC: B25H1/00
Filed: 1988-07-01
Abstract: In the case of the portable drilling machines on the market, it is not possible to drill at an angle, except in the axial direction, without correcting assistance from a second person. This is to be achieved by a levelling wheel without external assistance. The levelling wheel consists of a round disc into which a spirit level is set in order to be able to optically orientate the machine. The wheel is attached laterally to the drilling machine in a locating opening for it in the housing of the drilling machine and is clamped in place by means of a wing screw. Limited by a stop pin guided in a groove, the levelling wheel can be turned through 180@. Pre-setting of any requisite inclination in the drilling direction is thereby guaranteed. This levelling wheel is suitable for angular drilling in all planes, not only in an overhead manner but also perpendicularly without external assistance, in particular during tapping.

Title: Water-jet propulsion for propelling and steering watercraft
Inventor: DRACHE HEINZ-J
IPC: B63H25/46
Filed: 1988-12-29
Abstract: In order to avoid an intake opening in addition to the discharge openings at a constant delivery direction of a water-jet generator and in order to utilise the intake force of the water-jet generator for the force acting on the watercraft due to the discharging water jet, a radial pump is coupled to a reversing member in which a control flap rotatable through 90@, in its end positions, separates the suction and pressure side of the radial pump from one another. By intermediate positions of the control flap, the force acting on the watercraft can be regulated from zero up to a maximum value attainable by the pump, which force is formed from the suction and pressure force of the water-jet generator.

Patent DE-3942962-A1 (DE)
Inventor: KISSLER HERMANN DIPL ING
IPC: A62D3/40
Filed: 1989-12-23
Abstract: To dispose of liquid and gaseous substances containing halogenated hydrocarbon compounds and/or mixtures thereof, said substances are introduced in front of or into the flame of a gaseous or gasified fuel which forms water vapour on burning. The fuel is chosen and the flow rate of fuel, oxygen and the substances to be disposed of are adapted to each other so that free hydrogen is present in the waste gas and a temperature of at least 850  DEG C is reached. Water is sprayed into the hot stream of waste gas before the temperature of the waste gas falls below 800  DEG C. The sprayed water chills the waste gas stream to a temperature below 350  DEG C. The water-soluble, halogenated reaction products are then removed, together with the water vapour, by condensation.
