Patent DE-4218962-A1 (DE)
Title: Parting mechanism for wire - has cutters coupled to feed mechanism to give peripheral speed corresponding to feed speed of wire
Inventor: THEIS KLAUS DR
IPC: B21F1/02
Filed: 1992-06-10
Abstract: The wire is fed forward by a driven drawing disc, transport roller or straightening roller etc., and is parted off into bars, sections etc. The parting cutters (5, 7) are positively coupled to the feed mechanism (1), so that their peripheral speed corresponds to that at which the wire (6) is fed forward. The moment of inertia of the feed mechanism can be utilised to provide the necessary power at the time the cut is made. The parting mechanism can consist of two rotary cutter heads. Where the feed is by a straightening rotor, this can have a clutch and brake mechanism transmitting its moment of inertia when the cut is made. USE/ADVANTAGE - Simplicity of mfr. of wire parting mechanism.

Title: Decorative hologram panel - receives and reproduces holograms representing light sources at infinity
Inventor: WERNER WALTER DR
IPC: G03H1/22
Filed: 1992-11-04
Abstract: For receiving the holograms, the receiving plane contains a light sensitive medium (11). In this plane an objective beam (22,23) from a monochromatic source (1), e.g. a laser, is brought into interference with w reference beam (7). The latter may also be from the laser (1) and is coherent with the objective beam (22,23). On reaching the receiving plane, the objective beam (22,23) has substantially plane wave fronts. For reproducing the hologram, a holographic film (30) is brought into concise contact with one of the surfaces (32,33) of a flat, exposed, transparent substrate (31) or a glass plate. A monochromatic light source (34) emits light (35) at such an angle to the substrate (31) that the latter acts as a conductor for the light (35) due to total reflection at its surfaces (32,33). The total reflection is partially locally increased at the surface (32) contacting the film (300 in dependence on the hologram pattern. USE - Project images into narrow rooms to create illusion of more space, e.g. for decorating walls or corridors, subways, tunnels, etc. Also for use in theatres, concert halls, cinemas galleries, waiting room, etc.

Title: Method for producing patterned, coloured motifs and structures and colour image produced therefrom
Inventor: MARKOWSKY DIRK
IPC: B44D2/00
Filed: 1993-07-20
Abstract: The invention relates to a method of producing patterned, coloured motifs and structures and a colour image assembled from these motifs.   In order to produce coloured motifs and structures and a colour image which may be assembled therefrom, paints based on nitrocellulose or alkyl resin are applied, by a spraying method, to a liquid, untreated paint base, preferably water, and partially hardened to form a micro-paint layer which, after completion of the partial hardening, is transferred by mechanical means and/or by the application of solvents and/or by the application and partial hardening of further applications of paint, and subsequent skimming, onto a support material. The motifs or structures can be used for an individual representation or assembled to form a colour image, in which case, after drying of the support material, the applied design is fixed, for example, by application of a colourless coating layer.

Patent DE-4329215-A1 (DE)
Title: Rim brake for bicycles
Inventor: ENGEL ANDREAS
IPC: B62L1/12
Filed: 1993-08-31
Abstract: The invention relates to a rim brake for bicycles, in particular to the part concerned with the mounting of the two brake levers. The latter are mounted on a spindle which is arranged on a base part fixed on the frame and has a dihedron as a safeguard against rotation. This safeguard against rotation bears a retaining ring, the axial plane surfaces of which each have a groove which runs in the radial direction and in which in each case one spring end of helical springs can be placed in an exactly fitting manner in order to produce a locking form closure which, when the respective other spring ends are correctly fixed into brake levers which at this point have a hub, generates a spring preloading which moves the brake levers into their ready position against a stop provided by the Bowden cables. The advantage of the invention is simple assembly as well as the uniquely presettable ready position of the brake with sufficient play between the frictional partners of the rim and brake rubber. The use of an axially acting roller bearing avoids friction at the point of the largest rotational movement of components with respect to one another. Finally, a particularly effective seal against dirt at this point is achieved by means of a simple sealing ring or else by a plastic spherical holder which can be arranged outside the bearing as a sealing element between the hubs and has an increased diameter (Fig. 1). <IMAGE>

Title: Arrangement and process for reducing the water consumption in WC flushing cisterns
Inventor: PFEIFFER GUENTER DR
IPC: E03D1/14
Filed: 1993-09-25
Abstract: The invention relates to an arrangement and a process for reducing the water consumption in WC flushing cisterns. The object of the invention is to reduce the water consumption in WC flushing cisterns.   This object is achieved by a two-chamber flushing cistern, it being possible for the chamber volume in each of the two chambers to be different, but also the same. The installation of regulable main valves does not rule out this system and is advantageous. The two chambers are connected to one another via a connecting duct with a valve in one flow direction, with the result that either flushing water only flows out of one chamber - and thus only some of the entire water quantity is used - or, via the connecting duct, when the connecting valve is opened, the flushing-water quantity present in the two chambers is used. The advantage of this flushing cistern consists in that the water requirement for the flushing operation can be restricted and water can thus be saved.

Title: Brake pressure control system for car
Inventor: KOST FRIEDRICH DIPL ING
IPC: B60T8/40
Filed: 1993-12-01
Abstract: A brake pressure control system is described where the theoretical brake pressures are evaluated. From these, the valve control times are calculated and thereby, the actual brake pressure in the wheel cylinders is controlled. The wheel cylinder pressures are evaluated from the valve control times and the brake circuit pressure. These are utilised in the theoretical brake pressure evaluation. Additionally, there is a pump which makes it possible to generate higher pressures in the wheel cylinders than instigated by the driver. The brake pressures necessary for the theoretical brake pressure evaluation described above are evaluated using a computer model and measured pressures.
