Title: Roadside embankment earth and undergrowth clearing vehicle - with wormgear conveyor at rear on verge side and rotating broom
Inventor: RUPPERT WILHELM
IPC: E02F3/76
Filed: 1975-02-24
Abstract: The function of the vehicle is the clearing and removal of earth collected or piled up on the roadside verge or embankment, for which purpose it is equipped with a loading device mounted in front. At the rear, in the direction of travel, it is equipped with a clearing mechanism (3), operating continuously on the right-hand (or verge) side may be in the form of a wormgear conveyor. A rotating broom may also be mounted behind the clearing mechanism, and both may be driven, with the aid of gearing (8, 9), by a drive shaft (10) on the tail. With the wormgear conveyor working on the verge side the driver can follow the direction of road traffic, both clearing the unwanted material at the side of the road and moving it to the side. The rotating broom can clear the road surface at the same time, and no further vehicles are needed.

Title: Sheet metal verge for gable end of tiled roof - made in one piece by blanking and pressing
Inventor: BEIER KURT
IPC: B21D37/08
Filed: 1975-06-19
Abstract: Sheet metal verge for fixing a layer of roof tiles and covering the outer edges of the tiles on the gable end of the roof, has a side screen and a top surface which is bent downwards at one end to match the eave. The novelty is that the verge, including the downward bend in the top surface and the rounded curve where the bend blends into the side screen, is made in one piece from a flat sheet of metal without using a welded seam. The verge is blanked and pressed to shape without using any welding process, reducing the mfg. cost.

Title: Tights with open crutch at centre seam instead of gusset - with high elasticity, preventing inflammation due to irritation
Inventor: WILBERG CHARLOTTE DR MED
IPC: A41B11/14
Filed: 1975-06-30
Abstract: Tights have an open crutch at the centre seam instead of a gusset, with the centre seam remaining open 20-30 cm. from the front edge and 40-50 cm. from the rear edge, according to the size of the tights. The open crutch allows the tights to be stretched tight when pulled on, while maintaining high elasticity to allow freedom of movement at the hips and knees. It also prevents irritant phenomena such as eczema of the skin, or even inflammation of the lower abdomina organs, which are caused by perspiration and moisture because of the tights are knitted of synthetic fibre material which is non-absorbent.

Title: Ignition system for IC engines - has alternator as signal generator and threshold switch interrupting DC in primary winding
Inventor: WERNER PETER DIPL ING
IPC: F02P3/055
Filed: 1975-07-24
Abstract: The threshold switch has a controlled electronic switching paths. The ignition coil primary winding d. c. is controlled by the threshold switch, in turn controlled by a transistor with a storage component between the two, whose stored energy decreases when the engine speed increases. A further transistor forms with the control transistor a second threshold switch, as in 24 34 788. A control capacitor is charged by the d. c. voltage source and discharged by one of the two threshold switches. A control switch gradually interrupts the current through the ignition coil primary winding, when the engine is idle, depending on the control capacitor charge.

Title: Clear plastic screen for vehicle lights - is fitted as cassette to move clean plastic over lens
Inventor: AMANN PETER MARIO
IPC: B60S1/56
Filed: 1975-08-06
Abstract: The vehicle lights and the numberplate are fitted with hinged plastic frames which have special cassette holders at one end. Into these are fitted double spool cassettes of clear plastic foil. One spool is the supply reel and the other the take-up reel. A motor drive transports the foil periodically over the lens or numberplate in order to ensure a clear cover at all times. The one sided mounting of the cassette, with a return loop roller at the other side of the frame enables the system to be fitted in a confined space. The cassette is covered with a tear-off envelope which allows the film loop to be pulled out and looped over the return roller. This allows a speedy, simple replacement of the casette.
Patent DE-2542311-A1 (DE)
Title: Electrostatic dust precipitator - with increased precipitating field strength at positions between corona discharge points
Inventor: TASHIRO KOJI
IPC: B03C3/40
Filed: 1975-09-23
Abstract: In an electrostatic dust precipitator carrying discharge electrodes with corona discharge points and precipitation electrodes, the distance between the corona discharge points and the precipitation electrodes is greater than the shortest distance between the discharge electrodes and the precipitation electrode. i.e. the pptn. plate is corrugated while the discharge electrode is straight. This enables a higher field strength to be applied to the dust to be removed, with a shorter distance to the pptn. plate.

Title: Cyclising of polyacrylonitrile fibres by alkaline treatment - carried out continuously after spinning, etc.
Inventor: FESTER WALTER DIPL CHEM DR
IPC: D01F11/06
Filed: 1976-01-28
Abstract: Cyclising of polyacrylonitrile fibres by treatment with basic material followed by heating, in which the treatment is carried out before the end of the 'healing' process (closing of pores and elimination of internal cavities in the fibres.). The cyclising is pref. carried out during the continuous process of wet spinning, stretching, washing and healing, and may be simultaneous with the latter. Chemical treatment is performed before oxidn. and carbonisation to produce carbin fibres. Exothermic heat and damage to the fibres during subsequent heating are much reduced by a simple and economic continuous process which is suitable for both filament and staple yarns.

Title: Mine support linkage between roof and floor members - acts with telescopic ram to ensure balance between forward forces
Inventor: BUELL HANS ING GRAD
IPC: E21D23/00
Filed: 1976-04-17
Abstract: The mine roof support has two floor supports and roof supports interconnected by telescopic hydraulic rams. An advancing system is mounted on the floor supports behind a scraper conveyor, with the front part of the roof supports overhanging the conveyor. A set of swinging arms are between a lower pillar and a telescopic ram controlling the position of the roof supports. These arms describe an elliptical path to ensure the correct alignment of the roof supports as they are moved forwards or backwards, or angled. This control ram is divided into compartments interconnected with the hydraulic circuit so that the horizontal force component on the roof supports is always greater than on the floor supports during advance.

Title: Suitcase with reinforcement peripheral frame - has flat section strip and metal band with beading to cover join between base and lid
Inventor: LEHMANN KARL G
IPC: A45C5/02
Filed: 1976-12-23
Abstract: The suitcase comprises an upper part and a lower part which are reinforced around their opposing edges by a peripheral frame (12) of wood or chipboard. To this is attached a flat plastics strip (13) which is designed to take a metal band (11). Opposite the free edge side the strip is a board web (14) which forms a fastening surface having a bead (15) to cover the join.
