Title: Adjustable centre-board for sail-board - has foot-operated slider and includes side guide slots
Inventor: MARKER HANNES
IPC: B63B35/79
Filed: 1980-09-02
Abstract: The centreboard is located in the slot in the board by an axle (5) firmly fitted to the board and set between two grooves (4) in the sides of the slot. The groove has a vertical extension at one point to allow the centreboard to be extracted. Cable drives (11,12) attached to the centreboard are linked to two sliders (16,17) to allow foot operation to set the angle of the centreboard. A toothed profile for the top edge of the centreboard (8) meshes with a fixed rack (9) cut over the slot. This stabilises the centreboard setting and imparts a translational control when the angle of the centreboard is set.

Title: Extra flashing warning light for vehicle - fits against inside of raised bonnet or boot lid
Inventor: MACK WILHELM
IPC: B60Q1/48
Filed: 1980-12-04
Abstract: The warning light is located on the inside of the vehicle's bonnet or boot lid and flashes visibly when the bonnet or boot lid is raised. Two such lights may be present, one at each corner of the bonnet or boot lid. The lights are concealed when the bonnet or boot lid is closed. These extra warning lights make it less likely that the stationary vehicle will be overlooked by approaching traffic -- the normal flashing warning lights lower down on the bumper could be obscured e.g. by clothing.

Title: Method for cleaning curtains or the like, and machine for carrying out the method
Inventor: BENGEZ ZELJKO
IPC: D06F11/00
Filed: 1981-02-04
Abstract: A method of cleaning a curtain left in its hanging state is shown. For this purpose, the curtain to be cleaned is partially gathered together and moved at its upper hung-up end between a spraying device (30) and a suction device (20) mounted with spacing from the spraying device. The cleaning apparatus formed by the spraying device (30) and the suction device (20) is then moved downwards along the hanging direction of the curtain. During this movement, continuously successive portions of the curtain are soaked by a cleaning fluid which is discharged from spraying nozzles (34) of the spraying device (30) and, subsequent to the passage through the curtain, is sucked away by suction slots (24) of the suction device (20). <IMAGE>

Title: Hand-operated tool for cutting pieces of metal strip to length, in particular for producing pipe clamps or pipe fasteners
Inventor: DICK MATTHIAS
IPC: B21D5/02
Filed: 1981-02-27
Abstract: The invention starts from a hand-operated tool with a cut-off blade (6) which is rigidly fastened to a pressure arm (5), one end of which is pivotably connected to a base plate (1) and the other swing-out end of which is connected via a strap (9) to a hand lever (8) pivotably mounted on the base plate (1), and which interacts with an opposing cutter (15) supported against the base plate (1). So that true-to-size pieces of strip can be cut to length and provided with fastening holes in one operation, for example on a building site, by means of a hand-operated tool of this type, the cut-off blade (6) has cutting edges on both sides which interact with two opposing cutters (15) supported against the base plate (1). Furthermore, punches (10) are arranged on both sides of the cut-off blade (6) at an equal distance from its cutting edges. The punches (10) are fastened to the pressure arm (5) in such a way as to be pivotable about a pivot axis (11) parallel to the pivot axis (4) of the pressure arm (5), are displaceably guided in guide blocks (12) perpendicularly to a guideway for the strip material (17), and interact with dies (13) having cutting holes and supported against the base plate (1). <IMAGE>
Patent DE-3107798-A1 (DE)
Title: Printed imitation of strips of natural wood and method of producing impressions
Inventor: FISCHER WALTER
IPC: B44F9/02
Filed: 1981-02-28
Abstract: The printed imitations of strips of natural wood have pore-like impressions which are true to nature. In order to produce the impressions in the printed imitations, the imitations are unwound to pass over a roller, during which a matrix provided with embossings is brought into contact, continuously or at intervals, with the printed imitation, so that impressions having pores completely identical to the structure of the strips of natural wood are produced. The matrix is formed either by a rotating roller matrix or by a stamp matrix. Since the impressions are applied, corresponding to the natural wood structure, with identical pores and faithfully to nature, it is difficult even for a person skilled in the art to distinguish these embodiments from solid woods. The printed imitations are advantageously usable for interior decoration and for furniture.

Title: Digital signal transmission system, in particular for satellite broadcasting
Inventor: KLANK OTTO DIPL ING
IPC: H04H60/74
Filed: 1981-07-08
Abstract: Digital signal transmission system, in particular for satellite broadcasting. Bit words allocated to different programmes are transmitted in temporal succession within a master frame. A code bit is transmitted in each case after n programmes to identify the programme type. The code bits are evaluated in the receiver in a time-selective manner and are combined to form a sub-frame which has the same structure and the same number of bits as the master frame. The same synchronous word identification circuits and demultiplexer circuits can thus be used as for the master frame.

Patent DE-3135051-A1 (DE)
Title: Spring bracket
Inventor: KREID FERDINAND
IPC: H05K13/02
Filed: 1981-09-04
Abstract: In the case of electronic components which are provided with supply lead wires, the supply lead wires must be directed, bent and cut off for installation of the components. This is done in processing machines to which the components are supplied via supply strips. The previous brackets, in the form of hairpins, on such supply strips were unsatisfactory. A spring bracket is thus proposed according to the invention which consists of a two-layer limb which forms a sliding support for a moving limb, which is loaded by a spring, such that the supply lead wires are always gripped reliably virtually independently of their position within the spring bracket. <IMAGE>

Title: Transfer film, in particular for durable embedding of toner images
Inventor: HADERSBECK HANS ING GRAD
IPC: G03G7/00
Filed: 1981-10-02
Abstract: In connection with X-ray electrography, toner images must be transferred onto a transparent base by means of an extremely fine-grained powder and with very flat gradation, and durably embedded therein. This is carried out by means of a transfer film comprising a commercially available polyethylene terephthalate film onto which a gelatin coating has been applied with high adherence. Just before the toner image is transferred, the gelatin coating is temporarily softened, and the transfer coating prepared in this way is pressed onto the toner image using moderate pressure.

Filed: 1981-12-08
Abstract: The turn-and-tilt window or turn-and-tilt door has a wing which is equipped with a wing frame (2) and which is selectively rotatable about a vertical axis and tiltable about a horizontal axis. To this wing is assigned a fixed frame (1), the vertical spars (5) of which have at least one C-shaped or U-shaped anchoring groove (4) opened to the chamber (3) limited by the fixed frame and the wing frame. The turn-and-tilt window or turn-and-tilt door is equipped with a device (7) for setting intermediate openings between the closed position and the maximum tilt position of the wing. This device (7) has a fastening foot (6) which is mounted slidably in the anchoring groove (4) and bears positively against two mutually opposite groove walls and from which a cantilever (15) extends outwards from the chamber through the gap between the wing frame. The cantilever (15) is equipped outside the chamber with a coupling piece (17) which can be coupled to the wing frame (2) and which, in the coupling position, receives the stop edge (16) of the wing frame (2). The device (7) can be adjusted continuously along the anchoring groove (4) and thereby influences the opening position of the tilted wing. <IMAGE>
