Title: Appts for bending a steel plate - has formations of upper and lower punches hydraulically operated either side of plate
IPC: B21D11/20
Filed: 1974-01-11
Abstract: The apparatus is for bending a steel plate into any configuration having a compound curved surface. An upper punch group consists of at least three rows of punches aligning widthwise of the plate, disposed above it and adapted to form a curved surface for shaping the plate. A lower punch group consists of at least three rows of punches aligning widthwise of the steel plate and under it. The upper punch group is disposed so that the punches are individually adjustable in height, and the respective punch rows in the rows of punches can be arbitrarily preset in position w.r.t. the relative heights of the rows and the distances between the rows, as is the lower punch group.

Title: Eliminating nauseous gases from sewage treatment plant exhaust - by wet scrubbing plus adsorption with oxidising catalyst
IPC: B01D53/72
Filed: 1974-11-08
Abstract: In a process for destroying foul-smelling gases which have been extracted from a sewage treatment plant; the gases are eliminated by adsorption as they are carried through a porous element impregnated with an oxidising catalyst, e.g. pellets of aluminium charged with salts of Cr + Pt + Cu. Prior to the above oxidation, the gases are pref. wet-scrubbed in counter-current sprays of water containing organic matter and flowing at a rate of 1-10 l/s for every 5-10 I/s of gases. An addition of ozone is pref. made to the gases during the process, partic. at the point where the gases enter the scrubber. Used for purificn. of exhaust gases from sewage plants, e.g. 5-10 l/s arising from the sewage treatment plant for a town of about 20,000 inhabitants. Cost for destroying 98% of nauseous gases is low pre-scrubbing the gases prolongs catalyst life by two or three times.

Title: Electric field generating appts. - generates field whose vector is always vertical proving electrical-gravitational fields correlation
IPC: H02N1/00
Filed: 1975-11-25
Abstract: The method is designed to produce an electric field without a potential gradient. This gives rise to an electric field vector having a specifically vertical direction. An 'equipotential' or 'isopential field' is an homogeneous field where all the points in it are brought to the same potential. An equipotential or isopential field corresponds in fact to the characteristic of a 'homogeneous polarised field'. This means that the appearance of an electrid field vector with a specifically vertica direction in the space where there is an isopotential field has for consequence the modification of the value of gravitational acceleration G.

Abstract: Surface melting of solid materials or objects, esp. building elements, using an arc as a source of heat, the novelty being that a gas is fed through the arc so that the resulting directed plasma ensures the prodn. of the required heat. The arc is pref. generated using a low voltage direct current, the plasma source being located 2-80 mm from the surface being fused and the axis of the plasma jet is pref. at an angle of 10-90 degrees to the surface. The gas employed is pref. Ar, N2, air, a hydrocarbon, H2 or a mixt. thereof, and the surface may contain an inorganic pigment, esp. metal oxide. Several burners may be used in an automatic program, and a pref. burner design is claimed. Used e.g. for producing a glazed but porous surface on panels 12 m2 in 15 mins., the panels being used as facades in domestic or large industrial buildings using mass prodn. and pre-fabricated building elements. Using a value of 1 for the cost of facades produced by the invention, the use of coloured grey cement with limestone chips is 2.5. times more expensive, and the use of coloured plastics 4-6 times more expensive.

Title: Manual override control for vehicle air conditioning flap - has servo system valve flap moved by lever having two relatively pivotal parts
IPC: G05G7/04
Filed: 1976-03-17
Abstract: A lever (1) with a handle is fixed to a second shorter lever (2) by a pin (3). A spring (7) round the pin with its ends held against the two levers limits the relative rotation.

Title: Foam polyurethane base for suspended flooring - to key the flooring and absorb sound
IPC: E04F15/18
Filed: 1976-06-14
Abstract: Floor construction involving a solid foundation supporting pillars and beams for a suspended floor with space for heating conduits made of plastic tubing to run beneath the beams, where a layer of polyurethane foam is cast between the foundation and the suspended floor. The foam layer provides acoustic insulation and serves to anchor the beams to the foundation, acting throughout their length on three surfaces instead of requiring installation of mechanical or spot bonded anchorages at intervals, hence being relatively cheaply and quickly erected. The pipes are also secured, without being difficult to subsequently isolate and re-envelope with foam.
