Patent DE-3900058-A1 (DE)
Title: Hydrodynamic starter for motor vehicles
Inventor: GYOERY KALMAN
IPC: F02N5/02
Filed: 1989-01-03
Abstract: Hydrodynamic starter for motor vehicles, comprising a compression cylinder provided with a pressure piston driven by compression or tension springs, and furthermore consisting of a plurality of working cylinders which are mounted in the pressure pistons and in the end plates and are each equipped with a working piston mounted on a free-running shaft provided with two opposite coarse threads. At their ends, each of the shafts has a fixedly mounted gearwheel which, owing to the spring stress, exerts pressure on the hydraulic fluid in the pressure cylinder by means of the pressure piston likewise situated in the pressure cylinder. When required, the hydraulic fluid transmits the pressure exerted to an unlocked working cylinder. The working piston, which is provided with longitudinal guide grooves corresponding to the guide rails on the internal wall of the working cylinder can be moved only in direction A or B. By means of the movement brought about by the pressure, the working piston brings about a rotary motion in direction A or B at the shaft. The pinion and, as a result, the ring gear of the engine flywheel, is thereby set in motion by means of an interposed clutch and the engine started. Recovery of the energy expended is accomplished in exactly the opposite sequence, the hydraulic transmission of force likewise being reversed. Control is preferably effected electronically.

Title: Screw-free connection of the handle shells of a double-shell housing for an electric tool
Inventor: GEIS WILHELM DIPL ING
IPC: H01M50/247
Filed: 1989-01-21
Abstract: The connection of the two shell halves forming the handle part is effected, as a rule, by means of screws in the case of electric tools. To mount and detach the two handle shells, tools are required. The new connection does not require any screws and thereby enables a shortening of the mounting time and optimal shaping of the handle part. One handle-shell half (1) has at least one resilient tongue (3, 4) which projects beyond the separating plane (6), is equipped with a snap-in lug (2, 3) and is assigned a snap-in opening (14, 15) formed on the other shell half. Furthermore, centring means (11, 11') which correspond to one another are provided on both handle shells (1, 1').   <IMAGE>

Title: Colour printer for computers to produce prints with constant colour transitions
Inventor: REICHEL HILMAR
IPC: B41J2/21
Filed: 1989-07-10
Abstract: The optical impression of colours in colour printers is produced by a plurality of colours, e.g. red, yellow, blue and black, being positioned against one another to form an image pixel. As in the known screen printing, for example on paper, different colour impressions of the individual image parts are brought about by mixing the colours within the pixels and doing so over the entire image by their arrangement in terms of their colour, type and density. Needle printers with ink ribbons, ink film separation methods, thermal processes and the ink jet process are used for this purpose. The subject-matter of the invention is to provide means which already make any desired hue perceptible for the human eye in every individual pixel by dividing the surface of the individual partial colours.

Title: LF generator with binary coding switch - acts on first digital memory for frequency divider ratios
Inventor: BECKER PETER
IPC: H04H20/67
Filed: 1990-11-22
Abstract: The generator coding switch (10) selects a frequency from a series of frequencies (fO1-On), which are derived from a reference frequency (fR) by an adjustable frequency divider (15). The coding switch acts on a first digital memory (13) storing the dividing ratios for the frequency divider. The frequencies from the divider energises a bit counter (20), transmitting the read-out clock pulse (fT) for a second digital memory (23). In the latter the voltage stages (ST) of the frequencies, selectable by the coding switch, are deposited as a frequency-voltage table. The digital values from the second digital memory are converted in D/A converter (35) into analog voltage values. ADVANTAGE - Derivation of LF from only single reference frequency, without need for any filters.
Patent DE-4039100-A1 (DE)
Title: Adjustable-angle bus or aircraft seat - keeps leg-rest at comfortable angle in all positions
Inventor: NEUMANN ERWIN
IPC: B60N2/90
Filed: 1990-12-07
Abstract: The seat is particularly for a bus or aircraft, having a seat-cushion support adjustable for angle on a transverse axis, and to whose forward end a leg-rest is attached. A first drive adjusts the seal angle, and a second that of the leg-rest by means of a spindle slid in its lengthwise direction. The second drive mechanism is mounted on a slide (21) working in a guide (18) coupled to the seat structure between end postions in the direction of movement of the spindle (25). The slide is coupled to the seat-support (1) and leg-rest (2) so that when the latter swings out through a predetermined angle into one working position, it moves towards the leg-rest. When the support angle is reduced and that of the leg-rest simultaneously, the slide is moved away from the latter when the seat-support angle is above a predetermined second value. USE/ADVANTAGE - Ensures leg-rest slopes downwards sufficiently in all positions.

Patent DE-4102135-A1 (DE)
Inventor: SCHMIDT HEINZ
IPC: E03C1/044
Filed: 1991-01-25
Abstract: An electrically operated sanitary mixer tap system comprises a hollow piston (17) for adjusting the temperature, which in particular may be a rotary piston. The hollow piston (17) moves in a chamber (21) of the housing (1) of the mixer tap system, into which the flow paths (22, 23) for cold and hot water open. A particular structure (27) on the outside of the hollow piston (17) cooperates with the openings of the flow paths (23, 27) and thus determines the mixing ratio of the mixed water flowing out of the fitting. Its further path to the outlet of the sanitary fitting leads at least in regions through the interior of the hollow piston (17). Located at this point are (at least) the closing members (30, 34) of an electrically operated valve, which in this way controls the flow of mixed water to the outlet of the fitting. This arrangement of the closing members (30, 34) radially inside the hollow piston (17) facilitates a particularly space-saving construction (FIG. 4).
