Patent DE-2156172-A1 (DE)
Title: Yarn winding traverse - by two eccentric discs with yarn following their edges
IPC: B65H54/28
Filed: 1971-11-12
Abstract: The two eccentric discs, extending in a line parallel to the rotary axis of the bobbin being wound, have a gap between them for the yarn to pass through, the yarn being fed through a slotted yarn guide. The action of the edge of the eccentric discs on the yarn causes it to move across the line of the bobbin to give the required winding action to develop a cylindrical, conical or spherical yarn package. The reciprocal winding speed is increased by eliminating the problems of accelerating and decelerating a traversing mass at the extremes of the throw with conventional traverse linkages.

Title: Dehumidifying system for habitable rooms or drying chambers - removes moisture by cooling heat exchange with outdoor air
Inventor: BURGARD GUENTER
IPC: F24F3/147
Filed: 1973-12-03
Abstract: Air is drawn from the space being treated by a fan and passed through a cross flow heat exchanger in which it is cooled by heat exchange with outdoor air so that the moisture in it is condensed. The dehumidified air then returns to the room behind low level room heaters. The warmed outside air also passes into the room. The outdoor air is supplied by its own fan and a third fan exhausts a quantity of room air equal to the quantity of fresh air brought in. The amount of cooling and therefore dehumidification is controlled by variation of the speed of the outdoor supply fan and the exhaust fan speed is varied with it.

Title: Method of charging batteries and accumulators - charging is stopped when charging voltage increase stops
Inventor: BECHTOLD LEANDER ING GRAD
IPC: H02J7/00
Filed: 1974-06-26
Abstract: The charging system for individual accumulators or banks of such is intended to provide optimum charging, avoiding damage to the batteries and achieving the charge in the minimum time. The charging time, during which the full charging voltage is applied across the batteries is determined and controlled by an auxiliary voltage charging a capacitor to some value set automatically within fixed limits. This auxiliary voltage is always less than the charging level. The main charging voltage is removed using a relay circuit when its level falls below that of the capacitor, this being supplied from a constant current, variable frequency pulsed source.

Title: Domestic coffee maker with ready indicatotaator - incorporating bimetal strip to trigger signal when contents have been brewed
Inventor: BOLDT UDO
IPC: A47J31/54
Filed: 1974-06-27
Abstract: A cold water container is connected to an electric through-flow heater (1) controlled by a diaphragm pressure switch (3) which responds to the hydrostatic pressure of the fresh water column. An electrically heated bimetal strip (5) which is designed to trigger a signal is mounted parallel to the heating element for the through-flow heater whilst the diaphragm pressure switch (3) is provided with a reversal contact (4). When the cold water container is full of cold water, in the switch position (11) the through-flow heater (1) is switched on whilst in the circuit position (1) when the water container is empty, the heating for the bimetal strip (5) is switched on. Thus when all the cold water has been brewed up the bimetal strip is heated to bend and release the signal which shows that the drink is prepared and is being kept warm on the hot plate. Since the signal indicates there is no water in the cold water container it also prevents the machine from accidentally being operated dry.
