Title: Pharmaceutical or cosmetic aerosol spray - has medium and propellant aerosol kept separate before vaporisation of aerosol material
Inventor: SIEBERG ARNOLD
IPC: B65D83/14
Filed: 1975-09-11
Abstract: The aerosol device uses a normal aerosol container whose outlet valve is connected to a container for the spray material. The container is screwed to a nozzle piece, which can be pushed from above to operate the aerosol nozzle conventionally. The propellant passes up through a bore which at its upper end branches off to meet another bore for the spray material. The material which passes up the second bore is replaced by air entering the container through a narrow inlet bore. The propellant and spray material are thus stored and kept separately. The nozzle attachment can easily be removed from the container.

Title: Air foam tube orifice - has orifice from yielding material with opening smaller than first swirl orifice
Inventor: SCHICK PETER
IPC: A62C31/12
Filed: 1975-09-15
Abstract: A nozzle carrier (1) is connected to the foam supplying tube by strust (2) and contains a swirl orifice (3) with vanes (5). Behind the orifice (3) further orifice (6) is fitted made from elastic yielding material. The parts are kept in place by securing ring (7). During the operation the fluid pressure acting on the yielding material orifice reduces the wall thickness of the orifice to reduce its opening diameter, which results in pressure limiting. The additional orifice can be designed to be suitable for fitting to existing nozzles by an adaptor.

Title: Automatic reciprocal spooling unit - has proximity switch reversing movement of guide head on approaching drum flange
Inventor: KIND LOTHAR
IPC: B65H54/28
Filed: 1975-11-26
Abstract: The automatic spooling unit is for use with material wound onto a cylindrical former, the unit and the winding mechanism sliding to and fro in relation to each other for the width over which coiling takes place. To reverse this sliding movement, the unit (2) has an inductively or capacitatively operated proximity switch (8). On approaching the flange (9, 10) of the former or drum, this reverses the drive mechanism (3a). There can be separate proximity switches for each flange, or a single one working with both, and these can travel past the outside edge of the flange.

Title: Releasable connection for fixing inductor to transformer - has screw clamp moulding stem of inductive loop to angle bracket
Inventor: OVERKOTT FRANZ-JOSEF
IPC: H05B6/36
Filed: 1975-12-13
Abstract: The releasable connection, for fixing an inductor to a transformer, has the inductive loop (12) long stem clamped to an angle bracket (3,4) attached to the transformer connection piece (2). The clamp (15) consists of a ring that fits over the stem and one arm of the bracket and holds the two together by a screw-down block. The hole in the ring is shaped to follow the contours of the stem and bracket arm. Bracket arms and stem are divided into two insulated halves to provide 'to' and 'return' paths for the current. The advantage lies in the simple way in which the inductor can be changed.

Patent DE-2636668-A1 (DE)
Inventor: DAUMANN WINFRIED DIPL ING
IPC: H02M1/14
Filed: 1976-08-14
Abstract: An adjustment arrangement for a power converter system with a controllable semiconductor regulator to feed a DC current or DC voltage consumer or an intermediate DC voltage circuit of a converter from a DC voltage mains or a single-phase AC voltage mains while retaining essentially harmonic-free mains parameters contains, along with a first control circuit (30, 31, 32, 33) comprising a voltage controller (31) with a secondary current controller (33), a second control circuit comprising a selective filter (40) for the noise frequency and a proportional-action controller (42). The outputs of the first and second control circuits are fed to an adding station (34') whose output is connected to the control pulse former (50) of a control set to control the valves of the semiconductor regulator (14'). Due to the second control circuit, the noise frequencies are more accurately suppressed than with the use of purely passive elements. The control arrangement can be used in three-phase current drives of electric locomotives. <IMAGE>

Title: Mutual position determination of two or more strands - has strands rotated by little more than 360 degrees and then returned to initial position (NL 5.5.78)
Inventor: LANGOSCH HERBERT
IPC: H01B13/00
Filed: 1976-11-02
Abstract: The strands are parallel to each other, placed on a circle and of different colours. Their positions are detected by a stationery optoelectrical measuring device, with the strands rotated before the optical system about a fixed axis passing through the centre of the circle. The strands are rotated during a first step by a little more than 360 deg. The maximum value (2) appearing during this operation in the measuring device is stored. During a second step the strands are returned to their initial position, while an additional fixed value is applied to the measurement device. This ensures that the maximum value obtained during the first step is exceeded or not reached. This trips the signal determined by the measurement.

Title: Mixt. ratio regulator for IC engine - has oxygen sensor and integrating circuit with time constants preventing instability
Inventor: SCHNUERLE HANS
IPC: F02D41/14
Filed: 1976-11-19
Abstract: The fuel and air mixture regulator in an IC engine includes an oxygen sensor in the exhaust gas analysing system. The fuel is supplied by injection intermittently or continuously and is drawn in by the vacuum generated by the engine. The fuel can be supplied through an injection valve in relation to engine speed and the inlet air flow rate and can be supplied also in relation to a control pressure and continuously. Only a small number of switching elements are used in the control system. The sensor is connected directly to the inputs of the circuits. To the integration circuit (11) is connected a circuit for displacing the zero point of the output signal of the threshold value reference system at least in one direction for oxygen sensor signal. The integration circuit has two different time constants for rapid regulation of deviations and for preventing hunting in the regulation system at various rotating speeds of the engine.

Title: Leak detector using test gas - has set of parallel pipes and valves of different sizes and is connected to vacuum pump
Inventor: LENTGES GOTTFRIED DIPL ING
IPC: G01M3/20
Filed: 1977-03-28
