Title: Aircraft with twin rudders on wings with trailing-edge flaps - has ventilating flaps forward of others in wing section inboard of rudders
Inventor: RANSOM STEPHEN
IPC: B64C9/20
Filed: 1980-04-23
Abstract: The aircraft of canard configuration with twin rudders has these on either side of the fuselage, mounted on the wings which also have trailing-edge flaps. In the wing (6) portions between the fuselage (3) and rudder fins (1,2) there are ventilating flaps (11,12) immediately forward of the trailing-edge flaps (13,14), hinged along their forward edge. When raised, each flap opens a duct through the wing discharging ahead of the rudder hinge-line. Both sets of flaps extend full-width between the fuselage and rudder fin, remaining in contact with the fuselage at all angles. This portion of trailing-edge flap operates also as a trimming flap.

Title: Hydrostatic displacement machine has ring compressed by pistons - each with strong plastics facing bearing directly against ring
Inventor: GRABOWSKI GUENTER ING GRAD
IPC: F04B49/12
Filed: 1980-12-23
Abstract: A hydrostatic displacement machine comprises one or more adjusting pistons of metal for adjusting the stroke-generating ring, the surface of the piston which bears against the ring consists of a plastics layer. This plastics layer is pref. a plate-shaped object, firmly bonded to the piston, for example by gluing, vulcanising or screwing. The plastics layer of the plate is also pref. locked physically with the piston, for example by the projecting spigot of the piston. Pref. material for the plastics layer is a duroplastics, or a plastics reinforced with carbon fibres. The layer is pref. relatively thick for example 20-30% of the piston dia. With this arrangement, the face of the piston can bear directly against the ring and no intermediate shoe is required. The elasticity of the plastics layer enables slight errors in alignment to be accommodated.

Title: Foot treatment device with an air pump and vibration-generating and ozone-generating element
Inventor: FRENKEL WALTER
IPC: A61H23/02
Filed: 1981-01-21
Abstract: The invention relates to a foot treatment device combining several treatment principles. Arranged securely on the underside of the tub housing (4), which itself is capable of vibrating, are a vibration pump unit, consisting of a motor part (2) and pump part (3), as well as a chamber for generating ozone or for generating negative ions. The motor part produces the vibrational movement and drives the pump part, which draws in outside air and passes this via tubes through the chamber generating ozone or negative ions to the air-outlet nozzles (1) on the base of the tub, from which the air which has been ozonised or enriched with negative ions flows into the bath water present in the tub housing. The feet treated in this way are acted upon by three components: vibrational movements which reach the feet directly and via the water, the action of small bubbles which has a mild stimulating effect on the skin, and ozone or negative ion charging of the bath water, which has a disinfecting effect and generally promotes healing and strengthens. <IMAGE>

IPC: B27G5/00
Filed: 1981-02-21
Abstract: The subject matter of the invention is a method of producing furniture parts, such as, for example, door frames, profiled strips and the like, in which the workpieces are in the form of veneered or coated panels. The workpieces are mitre-cut into individual parts (26, 27, 28), the cut being made by means of saws arranged in a V-shape or form cutters and the workpiece being cut through completely, the cutting pressure resulting from below against the coating and against the running direction of the workpiece. The individual parts (26, 27 and 28) are assembled in a special folding device, the two outer parts (26 and 28) being transported by means of suction bands (34, 35) and swung to the inside. After the parts (26, 27, 28) are assembled, the suction action of the lateral bands (34, 35) is interrupted and the assembled workpiece runs into a following press station, while the folding device is opened for the entry of a further workpiece. <IMAGE>

Title: Method for shaping workpieces without cutting
Inventor: KOYDL LADISLAV DIPL ING
IPC: B22C9/06
Filed: 1981-03-27
Abstract: The invention describes a method for shaping workpieces without cutting. In this process, a casting mould has an outline which corresponds to the negative of the final shape of the workpiece. A wear-resistant layer is first applied to this outline, and is then covered by a reinforcing layer if so desired. Furthermore, the body of the actual workpiece itself is preferably cast from an alloy with a low melting point. The method is especially well suited for manufacturing deep-drawing dies workpieces, ingot moulds and all workpieces which must have a wear-resistant surface. <IMAGE>

Patent DE-3138431-A1 (DE)
Title: Method for emitting acoustic traffic signals synchronous with light signals and signal sound generator therefor
Inventor: OSTKAMP ANTON
IPC: G08G1/005
Filed: 1981-09-26
Abstract: Light signals from traffic signal installations indicate freed or blocked traffic routes, and thus protect the road user; thus in particular, pedestrians are protected at pedestrian crossings controlled by lights. The visually handicapped or blind cannot receive these optical signals; they remain without protection. Acoustic signals emitted simultaneously with the light signals are suitable for protecting this class of person as well if the acoustic signals stand out clearly from the surrounding noise. Given a high level of traffic noise, it is therefore necessary for the acoustic signal to be radiated with a high output power; this leads to an undesired environmental disturbance at times when traffic is light. Consequently, the acoustic signal is controlled as a function of the environmental noise level in such a way that starting from a basic signal level the level of the acoustic signal is maintained in a further level range at virtually the same distance from the environmental level. In the case of a plurality of crossings, or else of divided crossings, the individual crossings (or crossing segments) are assigned pulse and/or frequency characters, which are impressed on the acoustic signal and permit anybody visually impaired or blind to co-ordinate unambiguously the acoustic signal and freed crossing or crossing segment.

Title: Electrical capacitor and method of producing it
Inventor: LEUPOLD GERHARD DIPL PHYS
IPC: H01L29/00
Filed: 1981-12-03
Abstract: The invention relates to an electrical capacitor whose ceramic body (1) has, in particular, the form of a porous cylinder having a multiplicity of channels (12) extending axially alongside one another in parallel. The outer and inner surfaces of the ceramic porous body (1), which is preferably composed of strontium titanate, are doped using an impregnating solution of bismuth nitrate and doping additives and by a defined firing so as to produce a surface barrier layer which acts as a dielectric. The reduced core is brought out at an end face of the ceramic body (1) and here contact is made to it without a barrier layer by means of a metal layer (4) which is spaced apart from a second metal layer (2) on the surface of the ceramic body (1) so that the two metal layers (2 and 4) form the coatings of the capacitor which has a very high capacitance per unit volume. <IMAGE>

Title: Method and apparatus for striking the arc in a partially or fully mechanised welding process with fusible electrode
Inventor: JUNG WERNER DIPL-ING
IPC: B23K9/067
Filed: 1981-12-23
Abstract: The invention relates to a method and an apparatus for striking the arc in partially or fully mechanised arc welding, in particular in MIG/MAG welding with fusible wire electrode. To obtain reliable striking of the arc even under difficult working conditions, the mechanically fed wire electrode (12) is moved up to the workpiece contact before the arc is struck, is then automatically pulled back from the workpiece (10) until the arc is struck and is moved towards the workpiece again after the arc is struck for performing the welding operation. The reversal of the electrode movement from advance to retraction and vice versa is preferably effected as a function of the voltage in the welding circuit, although it could also be effected as a function of the current in the welding circuit or as a function of an adjustable time. <IMAGE>
