Patent DE-3001286-A1 (DE)
Title: Musical rhythm demonstrator - has circular disc with diametrically opposed peripheral edge portion and carrying striker
Inventor: BOISVERT ADRIEN J
IPC: G04F5/02
Filed: 1980-01-15
Abstract: The teaching aid for musicians has a circular disc eccentrically mounted on a motor-driven shaft which is rotatable at a constant, selected speed. The peripheral edge of the disc is eccentrically disposed with respect to the longitudinal axis of the shaft and portions of that edge provide a visual indication of musical rhythm or tempo as the disc rotates. A sounding device is associated with the disc to beat out time and augment the visual indication of tempo with an audible, repetitive sound. It also includes a striker carried by the disc, and a sounding device mounted in the path of travel of the striker to be struck once per revolution of the circular disc.

Title: Flat capacitor or resistor with metallised surface - has linear ridges on surface, not forming hindrance to capacitor, or resistor insertion
Inventor: SCHARRER WERNER
IPC: H01G2/06
Filed: 1980-01-19
Abstract: The flat components, e.g. disc-shaped, or trapezoidal, capacitors and resistors are particularly intended for application to printed circuit boards. The metallised surface of such components is intended for soldering onto such boards, or any other support member. The metallised surface is fitted with ridges (5), preferably linear, without any hindrance for mounting insertion. The ridges may intersect, or they can have additional punctiform formations. Alternately, both component surfaces (2,3) are metallised and fitted with such ridges. If the component is intended for insertion into a slot, the linear ridges extend approximately in the inserting direction. The ridges may also form a matrix. The angle elevation of the side edges of the ridges is typically 5 to 60 degrees.

Title: Ram-type test boring system - with leading point comprising concentric disc with diameters decreasing towards end
Inventor: MOLSNER HERMANN-DIETRICH
IPC: E21B10/40
Filed: 1980-02-20
Abstract: In a ram-type of test boring system the leading point consists of several concentric discs with diameters which decrease in steps towards the end. The periphery of each disc is designed as an annular cutting edge with a top rake and a clearance angle. Inclined grooves are arranged on each clearance face and the disc assembly can swivel relative to the drill rods. This eliminates the risk of conventional conical points of being deflected by rock and stressing the drill string to breaking point. The new leading point will not become wedged either.

Filed: 1980-03-12
Abstract: An apparatus for applying coatings possessing external projections onto continuous cores, e.g. for applying vinyl chloride coatings with discontinuous external projections onto a metallic pipe, consists of a discharge chamber attached to the outlet end of an extrusion cylinder. The pipe or core passes continuously through this discharge chamber, in which the coating is applied to it; the pipe and coating pass out from the chamber through an opening composed of a stationary extrusion mould (4) and a movable extrusion mould inside the chamber. The complete passage through these two extrusion moulds has a number of grooves formed in its surfaces so that as the movable mould (5) is rotated, these grooves may cone into alignment or out of alignment with each other. For coating of pipes and tubes and also for coating of timber or bamboo rods. The coating is for corrosion prevention and the apparatus enables serrations or ribs to be produced on its external surface, thus making it non-slip.

Title: Luminaire having a bulb-shaped gas discharge lamp
Inventor: HASEMANN FRED DR
IPC: F21V7/09
Filed: 1981-03-25
Abstract: In the case of a luminaire having a bulb-shaped gas discharge lamp which is suitable for lighting streets, it is possible to use both high-pressure sodium-vapour lamps and high-pressure mercury-vapour lamps. In order to achieve an evening out of the distribution of light intensity in the important planes of radiation to be considered here in the case of both lamp types, provision is made of light-directing and/or light-scattering sections at the high-gloss mirror reflectors in the regions of the maxima of light intensity in preferred planes. It is thus possible also to make use of high-pressure sodium-vapour lamps in luminaires which are designed for high-pressure mercury-vapour lamps. Preference is given to reflectors having sections with an appropriate saw-tooth profile, which lead, for example, to steeper exit angles with respect to the vertical in the preferred planes.

Title: Control device for a wind power converter
Inventor: GLOYER GERD ING GRAD
IPC: F03D7/02
Filed: 1981-11-28
Abstract: The invention relates to a control device for a wind power converter with adjustable rotor blades. The blade tips are pivotally mounted and under the effect of differing centrifugal forces assume different setting angles in relation to the rotor plane. The rotor shaft carries a displaceable synchronising device which acts against a force. The blade tip is likewise influenced by a force in its direction away from the rotor hub and the two forces are directed in opposition. The adjustment can be influenced by a control element regardless of the centrifugal forces. The blade tip is turned in a guide slot by means of a guide bolt in a plane which is attuned to the differing centrifugal forces. <IMAGE>

Title: Quick-action coupler on a three-point mounting device
Inventor: CONRAD ERNST
IPC: B60D1/04
Filed: 1981-12-07
Abstract: On a quick-action coupler on a three-point mounting device on agricultural machines, consisting of a hook on the lower link and of a coupling member in the form of a bush equipped with a frustoconical catchplate, the object to be achieved is to design the quick-action coupler so that no appreciable wear occurs either on the journal of the mounted appliance nor on the hook of the lower link and that the wear on the coupling member is also kept as low as possible. The invention achieves this object in that the outer face of the bush of the coupling member is cylindrical, in that the inner face of the bush of the coupling member has a hollow-spherical shape, in that this hollow-spherical space receives a spherically thickened tubular connection piece, and in that the bush carries a bead and/or a further catchplate on the side facing away from the catchplate. When this coupling member is used, wear on the journal of the mounting appliance and on the hook is largely prevented. But scarcely any wear can also be detected on the coupling member. This is because the hollow-cylindrical inner space of the tubular connection piece fits exactly onto the journal of the mounted appliance, and because the cylindrical outer face of the bush is located exactly in the hook of the lower link.
