Title: Adjustment movement indicator mechanism - uses markings on structural parts of valve to determine adjustment between components
Inventor: FISCHER GERHARD
IPC: G12B11/00
Filed: 1977-09-16
Abstract: The indicator mechanism uses structural parts (2, 4, 5) to monitor displacement movements between them. A marking (11) made on one of the two parts, preferably the stationary part (2), is designed as a scale which runs in the axial direction (A) and in the peripheral direction of the adjustable parts (5). Another marking (12) made on the other part in the form of a position indication, e.g. an arrow, is used to determine the relative position of the two structural parts. The scale marking may be made on a formable substrate fastened to one of the parts.

Title: Cylinder for cutting envelopes from paper strip - has cutter carrier and support cylinder on preloaded bearings preventing deflection
Inventor: HEYDEN GUENTER ING GRAD
IPC: B26F1/38
Filed: 1977-11-11
Abstract: The rotating cylinder press is used for punching out esp. letter envelope profiles from travelling paper strip.

Title: Wash-basin or bath outflow closure - has seal held by force dependent on pressure in overflow prevention system
Inventor: LANG GEORG
IPC: E03C1/242
Filed: 1978-06-14
Abstract: In the washbasing design is a seling unit acting in conjunction with the outflow, in the closing system for outflow from liquid containers, esp. wash-basins, bathtubs, shower troughs and similar, with an overflow safety device. This unit (24) is prestressed in the closing position, in the face of the direction of outflow, by a retaining force which can be overcome by pressure of a predetermined column of liq. attaining the overflow level. This has an impact effect on the sealing unit causing it to move automatically into the open position, where it is retained by the suction effect of the outflowing liquid. Retaining force may be adjustable in accordance with the prevailing overflow level. This is hygienically unexceptionable, and enables the sealing unit to form part of the overflow protection system.

Title: Large battery charging circuit - individually charges groups of cells at different times using transformer with several secondaries
Inventor: KOETHE HANS KURT DR ING
IPC: H02J7/00
Filed: 1978-06-24
Abstract: The charger comprises a transformer (7) with a number of secondary windings (8, 9, 14, 16). These windings are connected through rectifiers (10, 11, 15, 17) to separate groups of battery cells (1, 2, 3, 4). Switches (6, 13) in the leads are operated so that only two groups of cells are charging at any one time thus reducing the load demand and hence the size of the charger. The switches may be controlled by a timing device which selects each battery group in turn on a cyclic basis to ensure that the whole battery is always at an approximately uniform state of charge.

Title: Scanning and reproduction system for electronic copiers - uses multiple scanning of picture elements for improving signal=to=noise ratio
Inventor: KELLER HANS DR
IPC: H04N1/409
Filed: 1978-07-22
Abstract: The scanning system, esp. for electronic copiers, is designed to provide fast scanning and exposure times with good signal/noise ratio. The original is placed on a rotating drum and is scanned point-by-point and line-by-line via a lens. The scanner comprises a row of photo-diodes aligned with one picture line. The output signals from the diodes are passed to an electronic distributor comprising analogue multiplexers and demultiplexers. These are connected to integrators. The operation of the scanner and circuits is such that each picture element is scanned several times in succession and the respective signals are summed. The summing operation is synchronized to the relative movement between scanner and document.

Title: DC operated filament lamp - has built in rectifier and is operated in DC mode with rectification from AC supply
Inventor: HENGSTENBERG WERNER
IPC: H05B37/02
Filed: 1979-02-14
Abstract: An electric lamp with a built in rectifier allows the filament to be energised with a d.c supply, while coupled to the a.c mains. Experimental tests indicate that while the filament is subjected to a higher voltage with some 70% increase in current drawn, the developed illumination is increased by 170%. As a result of operating on a d.c. supply, the filament exhibits a greater load carrying capacity resulting in an improved operational life. In addition to the built-in rectifier is a transformer to allow the lamp to be operated at a lower voltage.

Title: Valve for carburettor slow running jet - has double action to prevent both overrunning and back-firing at different conditions
Inventor: BREITWIESER KARLHEINZ ING GRAD
IPC: F02M3/02
Filed: 1979-05-30
Abstract: The valve has a body with a nozzle in its end. A plunger is pressed by a spring against a seat on the nozzle to control the fuel flow. It is pulled against the spring by a membrane acted on by engine suction. When the engine is braking the vehicle the plunger is pulled to enrich the mixture which prevents backfiring. A sleeve round the plunger closes the fuel inlet through the body. It is pulled back against a spring by a solenoid energised from the ignition circuit. It thus shuts the fuel off when the ignition is turned off and prevents overrunning.

Title: Electric hair dryer - uses PTC heating element to limit temp. rise, and detachable waving slide with air holes
Inventor: NASSAU WERNER
IPC: A45D20/12
Filed: 1979-06-01
Abstract: Electrical hair dryer with add-on waver has self-regulating air throughput temp. when used with or without the waver stem. The hair dryer has a handle (1) containing the electric motor and blower fan. Air passes axially through the handle and passes over a heater (2) to an air outlet (3), the heater being made from a positive temp. coeff. material with output of 400-500W. An add-on stem (4) for waving hair can be fixed at the outlet (3) causing air to enter the stem and escape from radial outlet holes (5). Ordinarily, temp. would rise rapidly but since a P.T.C. heating system is used, this rise is severely limited and even without air flow, the temp. is not excessive.

The tappet has an annular shoulder forming the upper end of a cylindrical annular chamber subjected to the action of the inflowing working medium. The lower end of the chamber is formed by the annular surface enclosed by the valve seat in the body. The valve body (9) has an extension in line with the valve tappet (7) in the form of a bar (13) of the same cross-section as the tappet and the valve seat. A pressure equal to the suction pressure acts on the bar end face.

Patent DE-3008907-A1 (DE)
Inventor: ARREMANN HANS DR
IPC: H02M3/135
Filed: 1980-03-07
Abstract: A regulator has a main valve connected between a first terminal of a d-c source and a first terminal of a load. A first series circuit poled similarly to the main valve and including a commutating valve in series with a commutating capacitor is connected in parallel with the main valve. Another series circuit including the commutating valve, a reversing valve and a reversing choke is connected in parallel with the main valve and conducts current in the same direction. A swingback valve is connected in parallel with the reversing valve and poled oppositely. A second choke is connected in series with the capacitor in the first series circuit and the end of the second choke connected to the first load terminal is also connected to a second line terminal by a first bypass diode poled to carry the load current, and a second bypass valve is connected between the second load terminal and the end of the second choke connected to the capacitor and is also poled to be conductive to current flowing in the load when the main valve is non-conductive. With the main valve blocked, a very small voltage can thereby be impressed on the load without the occurrence of overvoltages at the capacitor.
