Patent DE-3103319-A1 (DE)
Title: Lip sealing ring
Inventor: JOHNEN ROLF
IPC: F16J15/3232
Filed: 1981-01-31
Abstract: A lip sealing ring is proposed, which interacts with a raceway and can be used in particular in the case of systems in which extreme operating conditions are present, such as a reduced pressure during operation and an excess pressure which occurs periodically when stationary. The seal has a membrane-like elastic extension which extends in the direction of the other race partner, originating from the raceway and/or from the housing of the lip sealing ring. When a pressure load is applied, said seal rests against the other race partner and hence protects the actual sealing lip against damage.

Title: Device for increasing the temperature of a heat carrier on the basis of the absorption and expulsion, evaporation and liquefaction of a coolant
Inventor: ZERWECK GUENTER DR
IPC: F28F21/04
Filed: 1981-04-01
Abstract: A device for increasing the temperature of a heat carrier on the basis of the absorption and expulsion, evaporation and liquefaction of a coolant, in particular an absorption heat pump or a heat transformer, has a multiplicity of heat transfer zones between the individual regions of the coolant circuit. In this case, a plurality of heat transfer zones are combined in a heat exchanger block (34, 35, 38) constructed as a counterflow plate heat exchanger. The single heat exchanger block (38) or the few heat exchanger blocks (34, 35) can be produced relatively easily from a suitable material of high corrosion resistance and thermal conductivity, e.g. a metal or a metal alloy, or even from a ceramic material, e.g. silicon nitrite. This renders it advantageously possible, e.g. in the case of absorption heat pumps, to make use of controllable oil burners and to utilise the flue gas heat as far as possible. Taking account of the respective optimum efficiency, the numerous heat exchange processes can therefore be substantially simplified, resulting in an economically justifiable practical implementation of such devices, in particular absorption heat pumps and heat transformers. <IMAGE>

Title: Roller pump for medical purposes
Inventor: MAHN DIETER ING GRAD
IPC: F04B43/12
Filed: 1981-04-08
Abstract: A roller pump for medical purposes comprises rolling bodies (6) which are mounted on a rotating support disc (5) and which can squeeze a conveying tube (1) locally in a working section (8) resting against a support wall (3) in order to cause a peristaltic conveying movement of the liquid in the conveying tube (1). In order to achieve a squeezing effect which is always sufficient for complete closure of the interior of the conveying tube (1) in the squeezed region (9), independently of production tolerances or the like, and on the other hand to rule out harmful excessive squeezing reliably, the support wall (3) is provided on a support part (2) movable in the supporting direction (arrow 23) and spring-loaded by a predetermined force in the direction toward the working section (8) of the conveying tube (1). As a result of this, the support part (2) can give way if increased squeezing pressures occur while it always produces exactly the squeezing pressure required. Furthermore, the support part (2) can be pulled down counter to the spring pressure into an assembly position in which the working section (8) of the conveying tube (1) is accessible for inspection and/or exchange. In this pulled-down assembly position the support part (2) can be locked, so that both hands are free for manipulating the conveying tube (1). Locking of the support part (2) in the assembly position can be cancelled by a release element (30) which is automatically pressed into its release position by the adjacent housing wall (12d) when the housing (12) of the roller pump is closed, so that it is ensured that the support part (2) is in its operating position when the housing is closed. <IMAGE>

Title: Control device having a control lever which can be displaced in two dimensions
Inventor: DUSCHKA HARTMUT ING GRAD
IPC: G05G9/047
Filed: 1981-06-24
Abstract: The invention relates to a control device having a control lever (2, 35), which can be displaced in two dimensions, for simultaneously controlling at least two different functions. In the case of different apparatuses, a series of control functions can be controlled simultaneously and the aim is to accommodate these functions in as few control devices as possible. To this end, the invention provides that the control lever be coupled to an actuating element (17, 39) which controls an electrical signal transmitter (15, 18, 24, 25, 26, 27, 28, 29, 50, 51). The actuating element may additionally be a plate which is slotted in accordance with a coded key and can be displaced between at least one light source (30 to 34) and an opto-electrical transducer (24 to 29, 50, 51), which is aligned with the light source, relative to the transducer. A control device according to the invention is particularly suitable for use on X-ray apparatuses. <IMAGE>

Title: Two-stage servo valve with mechanical feedback
Inventor: ITALY PAVEL DIPL ING
IPC: F15B9/08
Filed: 1981-06-25
Abstract: The invention relates to a mechanical/hydraulic two-stage servo valve with mechanical feedback. The essence of the invention consists in the fact that a shaft is mounted in a rotatable and displaceable manner in the longitudinal axis of the cylindrical slide valve, which is mounted in a rotatable and displaceable manner in the housing. A rotary slide valve is formed on the shaft. The rotary slide valve forms two control chambers which are connected to the spaces behind the guide extensions which are formed on the cylindrical slide valve, on which control extensions are also formed. In the centre part of the cylindrical slide valve, a choke opening connected to the waste chamber is formed at the location of the rotary slide valve. At the same time, an axially free and rotatably fixed bearing is formed on the cylindrical slide valve. A lever for the feedback is mounted on the bearing. The lever is led out of the housing of the servo valve. The servo valve can advantageously be used for the control of the geometric volume of hydrostatic transmissions.

Title: Method and arrangement for obtaining heating and/or cooling energy from the environment
Inventor: GLASER HORST
IPC: E04D13/18
Filed: 1981-08-19
Abstract: Individual ducts (8, 81) are formed for example into the two halves of an energy roof (2) designed as a ridge roof in such a manner that the air can enter at their lower end from openings (11) and at the upper end flow into two separate collecting ducts (141, 151) mounted in a ridge capping (131). From the central part of the collecting ducts, the air flows through intermediate ducts (17, 171) into a mixing chamber (23) before it is led through a heat exchanger (24) and/or a heat exchanger (31) of a heat pump (20). The passage cross-sections from the individual ducts (8, 81) into the collecting ducts (141, 151) and from these into the mixing chamber (23) can in each case be controlled in such a manner that an optimum and to a great extent uniform mixing temperature is achieved, which can be used directly or via a converter such as the heat pump (20) for heating or cooling. For controlling the temperature in the mixing chamber, use is made of outlet valves (25, 251) connected upstream of the latter, which are controlled by a control device (27) depending upon measurement values from temperature feelers (28, 281 and 29) in such a manner that always the air from the warmer intermediate duct (141 or 151) is preferably supplied. It is also possible, on entry into the collecting line (141, 151), automatically to throttle the flow, for example thermostatically, at least of individual ducts. In the case of given environmental conditions, the heat yield is improved by this selection and control. <IMAGE>
