Title: Pressurised fluid connection system - communicates between rotational body and machine parts using grooves, holes and tubular feeder, to release friction coupling
Inventor: BACHMEIR XAVER
IPC: F16B4/00
Filed: 1990-04-10
Abstract: The pressurised fluid communication system between a  rotational body (1) and a number of coaxial machine-parts (2, 3, 4) positioned on it (1), has a number of grooves (5, 6, 7) on the peripheral surface of the rotational body (1). A number of holes (8, 9, 10) run from the inside of the rotational body (1) to the grooves (5, 6, 7). All the holes (8, 9, 10) start from a single supply hole (11) inside the rotational body (1) parallel to its lengthwise axis. A tubular feeder (13) closed at one end and positioned in the supply hole (11) by means of positioning aids connects the holes (8, 9, 10) with the pressurised fluid source (12). USE/ADVANTAGE - The number of holes for introducing oil to the separate grooves into the cylindrical rotational body is reduced. Friction couplings between a central shaft and machine elements on the shaft may be released by feeding high-pressure oil to the interface between the shaft and the components.

Title: Two-stroke engine with double pistons - has smaller piston for combustion chamber operation, air intake low compression larger piston for combustion chamber with high compression
Inventor: WUERTH GUSTAV DR
IPC: F02B75/02
Filed: 1991-05-13

The larger piston takes-in fresh air, compresses it, and passes it via a conduit into the combustion chamber of the twin cylinder. The high compression takes place in the combustion chamber. There is fuel injection, and combustion is acc. to the Otto- or Diesel principle. ADVANTAGE - Low construction; increased air intake; high compression; longer service life.
Patent DE-4117503-A1 (DE)
Inventor: FISCHER ARTUR PROF DR
IPC: F16B13/12
Filed: 1991-05-29
Abstract: 2.1 Normally, plastic expanding dowels have a longitudinal slot which originates from the front end, and a longitudinal hole for the insertion of an attachment screw, which longitudinal hole, after a cylindrical section corresponding approximately to the external diameter of the screw, merges into a conical tapered section. 
<??>2.2 In order to reduce the screwing-in resistance, it is proposed that the cylindrical section (3a) of the longitudinal hole (3) taper at right angles to the plane of the slot down to the slot width, and that, in the plane of the slot, the diameter of the cylindrical section (3a) be approximately maintained in the region of the tapered section (3b).

Title: Preheating circuitry for cold-start of diesel engine - has sensor detecting occupancy of driver's seat in motor vehicle
Inventor: SMOLKA HELMUT
IPC: G08B21/22
Filed: 1991-06-28
Abstract: The driving position has an out of contact sensor for seat occupancy. As soon as the driving seat is coupled the sensor activates the glow-plug circuit to minimise the delay time in starting the vehicle. A simple IR sensor mounted under the steering column provides a reliable sensor. The IR sensor is fitted with an aperture to limit the field of scan to cover the width of the driving seat. This ensures that rear seat passengers do not cause premature activation of the glow-plug circuit. The circuit is further controlled by time and temp. with longer preheating applied in colder conditions. ADVANTAGE - Automatic glow-plug operation; reduces starting delay.
Patent DE-4124514-A1 (DE)
Inventor: SCHMID HANS-DIETER DIPL ING DR
IPC: H01H35/14
Filed: 1991-07-24
Abstract: In an acceleration sensor (10) for the automatic triggering of passenger protection devices in motor vehicles, a ball (15) acting as an inertia body is fitted in the base (13) of a chamber (14) with obliquely rising side walls (27) where it projects through an aperture (20) and is held in the basic position by a magnet (16). In addition, the ends of two mechanically prestressed contact springs (22, 23) bear on the side of the ball (15) facing the magnet (16). The contact springs (22, 23) are connected to leads for the measurement signal. When the ball (15) moves from the basic portion, the contact springs (22, 23) are opened so that an electric circuit is interrupted to trigger the passenger protection devices. The acceleration sensor (10) has a very short response time and is very economical to produce.

Inventor: ZEISER MANFRED P DR
IPC: A61C13/01
Filed: 1991-08-08
Abstract: A dental plate in plastic for the upper jaw of a person is produced in two successive stages by separate polymerisation processes. A silicone polymer cured in the mould is partially cut away and the cavity filled with cold or hot curing polymer or thermoplastic copolymer. After removal of the remaining silicone the cavity formed is again filled with plastic which cures in contact with the first part. USE/ADVANTAGE - The plate is used in dental work to rectify defects in the upper jaw, allows chewing after tooth loss and enables a very close fit to be achieved with the palate and avoids gaps around the edges

Inventor: BARTSCH ERHARD
IPC: B60H1/00
Filed: 1991-10-26
Abstract: The airflow through the heating/ventilation system of the vehicle has a main control flap (8) to divert a controlled flow past the heat exchanger (7) and to the facial jets.

The second control flap position is linked to the main control flap position, either by a direct mechanical linkage or by servo motors. A solar heating monitor (15) on the dashboard provides a control signal for increasing the cool air flow to the facial levels.
Patent DE-4201071-A1 (DE)
Inventor: GROTEPASS JOHANN
IPC: C21D9/573
Filed: 1992-01-17
Abstract: In a method for minimising the crop end losses of concrete ribbed bars during their edge treatment by controlled cooling at rolling temperature, cooling being carried out, after the emergence of the bar from a bar finishing block, in a cooling section having a plurality of cooling tubes in series between the finishing block and a downstream loop layer and the bar being introduced into the loop layer after edge treatment, a significant reduction in the crop end losses is achieved by virtue of the fact that the cooling for comparatively thin bar thickness of between 6 and 10 mm is shifted into an area of the cooling section nearest to the loop layer. <IMAGE>

Title: Pneumatic shears with adaptable transmission - has geometrically designed inner edges to cutter blades to act as guide for rollers fixed on end of piston
Inventor: MOESINGER HEINRICH DR ING
IPC: B26B15/00
Filed: 1992-04-27

Filed: 1992-04-29
Abstract: The optical equipment gives mono-axial alteration of a parallel laser beam cross-section for anamorphotic illustration. The beam from the source (1) diverges and passes through a positive lens (2). The beam is deflected by two successive grids or diffraction gratings (3, 4) including an angle. The equipment is achromatic in the vicinity of the mean wavelength of the laser beam.

Patent DE-4219201-A1 (DE)
Title: Keyless release mechanism for angle-grinder tool - has wedge thrust radially inwards to couple tool spindle to driving gear and prevent axial spindle movement
Inventor: SCHMIDT ALFRED DIPL ING
IPC: B24B45/00
Filed: 1992-06-12
Abstract: The tool is mounted on the flange of a spindle sleeve (4), against which it is clamped by a nut (10) on the spindle itself (8). A clamping coupling when released allows relative axial movement between spindle and sleeve, thus relieving the axial load on the nut, while when engaged both spindle and sleeve are driven by a gearwheel (3). The coupling is formed by one or more wedges (19) between an annular flange (15) on the spindle and the gearwheel. To engage the spindle with the gearwheel, with which the sleeve rotates, the wedge is thrust radially inwards by a clamping body (20). This fits in a ring (21) concentric to the spindle and which contains a recess (23), into which the body expands radially when released, allowing axial spindle movement. An actuating mechanism locks the ring in position. USE/ADVANTAGE - Easy tool removal from angle grinder without chuck key.
Patent DE-4221880-A1 (DE)
Inventor: WUNDERLICH JENS-CHRISTIAN
IPC: A61K9/14
Filed: 1992-07-03
Abstract: Active substances, such as drugs, which are not readily soluble in water, are converted to the dissolved (molecular-dispersed) state by dissolving them in a hydrophilic peptide with a molecular weight of more than 100 Daltons, such as a gelatin. This ensures the solubility of the drugs both during storage and when the preparation is used by the end-user or patient, without the need for organic solvents or for solubilizers with undesirable side-effects.
