Patent DE-2651196-A1 (DE)
Title: Switching power supply unit for TV receiver - has switch whose closing time in stand-by state is shortened, preventing frequency becoming audible
Inventor: OHE WILFRIED V D
IPC: H04N3/185
Filed: 1976-11-10
Abstract: The unit has a transformer with an electronic switch connected to its primary winding, periodically made conducting by a threshold element. A circuit controls the ON time by a rectified transformer pulsed voltage, thus controlling operational voltages are dervied from the transformer secondary winding. For standby operation a very low impedance can be connected to the secondary winding, so that operational values are no longer sufficient for the set operation. In stand-by operation with a transformer switch closed, the control circuit is so switched over that the ON period of the electronic switch is shorted in comparison with normal operation, preventing drop of operational frequency to the human audible range.

Title: System for producing cleansing foam - having twin piston pneumatically operated to pump liquid followed by air injection
IPC: B08B3/00
Filed: 1976-09-24
Abstract: Foam is produced in liquids esp. water to which chemicals have been added using a pair of cylinders joined by a common piston. These pumps from a ring main via non-return valves which allow suction and exhaust into a common main. Air is then injected into this main to create the foam. The piston action is controlled by air valves on a compressed air distribution system. Limit switches sense the motion of the piston and arrange for the air signal to turned over by a slide valve. The reciprocating action ensures a smooth delivery since each cylinder discharges alternately as the other draws in a charge. For use in preparing a jet of cleansing foam esp. for cleaning butcheries and butcher's implements to remove fatty deposits and odorus materials. The system provides continuous jet without the use of injectors.

Title: Washing machine motor control circuit - has tachogenerator whose voltage is added to reference voltage to give nominal speed signal
Inventor: WALTER BERNHARD DIPL ING
IPC: H02P25/14
Filed: 1977-04-07
Abstract: The motor is a single phase asynchronous motor with pole changing and a capacitor for different speeds. The asynchronous motor drives a tachogenerator and there is a bidirectional electronic switch in series with the motor. The tachogenerator supplies a summator which adds the tachogenerator voltage and a DC voltage corresponding to the motor nominal speed. The summator output is applied to an amplifier allocated to a capacitor charge circuit and a threshold switch is inserted between the control electrode and the capacitor, switched by the capacitor voltage during each half-period of mains voltage. When switched it delivers an ignition pulse to the electronic switch control electrode; a switch is connected in parallel with the capacitor, switching at zero crossings of main voltage. It short-circuits the capacitor.

Title: Radiation procedure to brown skin - using long-sleeved glove with openings closed by flaps to determine pigmentation grade before radiation stage proper
Inventor: MUTZHAS MAXIMILIAN FRIEDRICH D
IPC: A61N5/00
Filed: 1977-10-07
Abstract: The radiation procedure produces direct or indirect pigmentation of the skin within a short radiation time without erythema. The effective rays are of higher intensity than naturally arise in the earth's atmosphere and react with the browning skin particles. A test radiation can precede the radiation proper. This can be directed to the curve of the forearm. The latter can be covered by a long-sleeved glove of good reflective material in the U.V. wavelength. Openings are made in the glove which can be closed by flaps. A colour scale can be used to determine the grade of pigmentation.

Title: Quick-acting optical cut=off - has vacuum or gas layer between glass components to reflect to side when gap exceed 0.2 mm
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: G02F1/19
Filed: 1978-01-27
Abstract: A quick-acting optical cut-off obviates a material shutter as the opaque blocking medium. Instead, it uses a vacuum or gas layer transparent to the extent that it operates according to the refraction principle when the angle of incidence (V1) exceeds a critical value. Bridging surfaces (3, 4) in the same plane on the glass components (1, 2) of the cut-off effect its closure by distancing of the refraction layer's thickness (h greater than O). The refraction constants of the components (1, 2) are equal and selected so that by bridging from one direction (S1) in the vacuum or gas layer effects a total reflection at right angles (S3). When h = O it travels straight through to appear at (S2, S4).

Title: Tablet dispenser requiring no ejector element - with dispensing recesses on rim of rotatable storage drum
IPC: B65D83/04
Filed: 1978-05-24
Abstract: A tablet dispenser consists of a storage drum which lies rotatably inclined in a housing with its open end downwards and its closed end designed as a knurled knob. The rim of the open drum end has several individual recesses to accept a flat tablet. Turning the knob transports a tablet to an outlet through which the tablet is dispensed. This requires no ejector element or other moving parts in which the tablets may jam. The new dispenser has thus a higher functional reliability and is simpler to operate and to fill.
