Patent DE-2456424-A1 (DE)
Title: Self levelling suspension - with single height monitor in centre of control rod linked to wheels of one axle
Inventor: BUFLER ERNST DIPL ING
IPC: B60G17/02
Filed: 1974-11-29
Abstract: The self levelling suspension is simplified by having only one axle adjustable, namely that axle which does not carry the weight of the engine. The wheels are supported by main springs which are height adjustable and by subsidiary springs, which are not adjustable and which are in series with the main springs. The single height monitor is mounted in the middle of the axle and is operated by a lever attached to a torsion rod which links the two wheel supports at points between the two sets of springs. This greatly reduces the hydraulic control system for the axle.

Title: Capacitor control of voltage converters - is arranged so that only one switching transistor is active at any one time while others are at zero or infinite resistance
IPC: H02M3/07
Filed: 1975-03-15
Abstract: The voltage converter is intended to modulate the output voltage shape at the same time as effecting an upwards transformation. Capacitors are charged in parallel from a d.c. source and then connected into series by switching transistors. The modulation with high efficiency is achieved by operating only one transistor in the dynamic region whilst the others are at zero or infinite resistance. The diodes in parallel with the capacitors and transistors provide the path to the HT terminals bypassing the blocked transistors, and also assist in forcing voltage sharing between the series connected elements. The modulation is controlled by the time at which successive transistors are switched.

Patent DE-2710644-A1 (DE)
Inventor: ROTHENBERGER JAKOB
IPC: F16K31/06
Filed: 1977-03-11
Abstract: In solenoid valves for the control of high-pressure fluid, experience has shown that an adhesion force arises between the spool (2) and the housing bore (3) after a certain time at rest and this force is greater than that which would correspond to the normal frictional resistance to be overcome at the beginning of a spool stroke. In order to be able to overcome this adhesion force more easily, the spool (2) is, in one end position, partially relieved of the axial pressure arising in service. This can be accomplished by means of a spring (10) which holds the spool (2) virtually in a floating condition. Spool-controlled branch conduits (14, 15) can also be provided, these being used to bring about hydraulic pressurisation of differential annular spool faces (16, 17). <IMAGE>

Title: Warming cabinet for paraffin wax packs - with perforated vertical partitions at ends of grid decks for packs
Inventor: BERGER RAIMUND DR
IPC: B01L7/00
Filed: 1977-04-27
Abstract: A warming cabinet for paraffin wax packs has to keep a temperature accurate to within one-tenth of one degree Centigrade if the patient is to receive the maximum benefit over the longest time for a pack application. This has been achieved by providing vertical perforated partitions at both ends of the decks of grids on which the paraffin wax packs in their trays are supported. The rows of perforations lie halfway between the decks so that the air which enters at a pressure passes the packs with a slight turbulence. This reaches all uneven spots on both surfaces of the packs and ensures a uniform temp. A thermostat controls the temperature. The clearance between decks is made twice the height of a tray. The preferred diameter of the perforations in the partitions is 10 mm.
