Patent DE-3000297-A1 (DE)
Title: Underpressure heat pump for heating systems - has ambient air inlet port on cold side, with air filter, pressure reduction valve and expansion vessel with constant underpressure
Inventor: DERER ANDREAS
IPC: F25B30/00
Filed: 1980-01-05
Abstract: The pressure reduction valve can be a correspondingly dimensioned aperture, admitting only certain pressure in the expansion vessel (d). In the latter, the air pressure is lower than the atmospheric on the cold side. There is fitted a heat exchanger (e), coupled by a pipe line to the expansion vessel. The heat exchanger is mounted in a container (f) with inlet and outlet apertures. To the heat exchanger is connected an evacuator (g), such as a fan, an air pump, and a compressor etc. The evacuator delivers from the cold side, expanded air to the system hot side, against a pressure equal, at least, to atmospheric. On the hot side is provided an aperture (h), in front of which is connected a control valve (i), for delivery of air heated by the evacuation from the cold side, e.g. during a transition period. On the hot side is provided a second heat exchanger (k), coupled by a pipe to the evacuator.

Title: Shaft rotation limitation system - has stop sliding on disc driven via reduction gear and actuated by cams
Inventor: BERENS HEINRICH DIPL ING
IPC: F16D3/10
Filed: 1980-03-06
Abstract: The low-elasticity mechanical system limits the angle of rotation of a shaft through more than 360 deg., using sliding stops controlled by a reduction gear and acting directly on the shaft. One stop (9) is formed by a boss secured to the periphery of the housing so that it cannot turn in relation to the latter (3), while the other double one slides on a disc (8) turned about the centre of the shaft (1) via a reduction gear (5,6) at a lower angular velocity than the shaft. The double stop is thrust by cams (18,18') keyed (14,15) to the shaft radially against the first one (9) so as to limit shaft rotation. The equipment thus takes up little space in the axial direction, independently of the shaft diameter, the disc (8) indicating the shaft position.

Title: Moulded sail board with reinforcing inserts - has pattern of ties with perforated mats or fabric
Inventor: WINTERSBERGER LUTZ ALOIS
IPC: B63B35/79
Filed: 1980-06-18
Abstract: The moulded surf- or sail-board with reinforcing inserts has stiffening struts (51) running the length of the board, as well as surface reinforcement comprising perforated matting laid under the surface. The reinforcement is wire or rope and provides a strong, lightweight structure. Additional strength is obtained using a hollow structure with a central cavity (52) surrounded by the reinforced inserts. The tail fin is thus reinforced, while the centreboard is a separate fitting. The mast socket is strengthened to allow the use of otherwise low strength plastics for the board.

Title: Container for paper tissues - has inclined slot connected to two other slots arranged on alternate sides of pack to permit safe removal of one tissue
Inventor: VOGELSANG GEB KAPER
IPC: B65D83/08
Filed: 1980-09-18
Abstract: The container for paper tissues has an inclined slot with the slots (A and B) arranged on alternate sides. This ensures a safe gripping of the tissues folded alternately in different directions. The inclined slot ensures that the finger width slot obtained by the connection of the inclined slot with slots (A and B) extends transversely across the pack and thus above the tissues with their alternately folded grip folds. This facilitates the removal of any one tissue from the pack. The alternately sided slots also ensure that the slot remains stable and remains largely closed after removal of a tissue.

Title: Measuring electrical values of discrete semiconductor components - by varying reference value until minimal discrepancy is obtained
Inventor: SZTANKO JOZSEF
IPC: G01R31/26
Filed: 1980-10-23
Abstract: A method measuring electrical qualities of electrical components is esp. applicable to discrete semiconducting components. It involves the reference principle whereby an automatic 'Go - nogo' circuit is used. Currents in the nA range and even lower can be measured. A reference signal is varied so as to minimise the difference between the measured value and the reference signal. The reference value is successively varied to produce successive approximations until a minimal difference is achieved. When this has occurred the corresp. absolute value is generated and/or stored. The parasitic leakages parallel to the measured device are divided into two parts and a shunt formed to the measurement system ground.

Title: Exhaust turbocharger driving a compressor for an internal combustion engine operated at variable load and speed
Inventor: MANZ PETER WOLFGANG DIPL ING
IPC: F01D17/14
Filed: 1981-02-13
Abstract: In the case of an exhaust turbocharger driving a compressor for an internal combustion engine operated at variable load and speed the impeller is designed so that it functions on the constant pressure principle; in order to increase the charge pressure obtained in the lower speed range and to improve the response behaviour at least one pivoting flap is arranged in the housing of the turbocharger so that as it pivots it varies the circumferential area of the impeller against which the exhaust gases flow. The flap is connected to a control device which, sensing the charging pressure at any given time, in the event of low charging pressures swivels the flap so that the exhaust gases then flow only against a reduced circumferential area of the impeller and the exhaust flow cross section is accordingly reduced. <IMAGE>

Title: Variable conveyor belt loop on a travelling tripper of a reversible conveyor belt installation
Inventor: TSCHERNATSCH GUENTHER
IPC: B65G47/95
Filed: 1981-03-03
Abstract: In order to enable travelling trippers to be used both for unstorage operation and storage operation, the belt loop is generally released or reversed. To this end, one of the conventional solutions uses a vibrating support, carrying a deflector cylinder at each of its two ends, which is connected by alternately actuatable lifting devices to the travelling tripper. The object is to develop a travelling tripper with vibrating support in such a manner that the conversion of the belt loop can take place with optimum operational reliability and speed, the belt losses occurring being as low as possible and the belt tension forces loading the support system only for a relatively short time. According to the invention, the spindles of the deflector cylinders (8; 9) of the vibrating support (7) are guided in two opposite pairs of cranks (12, 13), arranged on the frame of the travelling tripper, and two additional deflector cylinders (16, 17) are each arranged to be invariable as to height, or one deflector cylinder (16), which is active during unstorage, is invariable as to height and the other deflector drum (17) is variable as to height. <IMAGE>

Title: Arrangement for damping a pendulum
Inventor: FEIST WIELAND DIPL ING DR
IPC: G01D11/10
Filed: 1981-04-24
Abstract: An arrangement for damping a pendulum, oscillating in at least one plane, for geodetic instruments. In these instruments, an irregularity of the pendulum, and thus of the image appearing in a telescope or reading microscope, frequently occurs in accordance with the external conditions, which causes measurement errors. To dampen this irregularity effectively, the pendulum is provided with a position detector and with a control circuit and an electrodynamic drive for each plane of vibration. For damping to occur direction-dependently and in dependence on the pendulum excursion independently of the respective equilibrium position, the control circuit contains circuit means, for example a capacitor, for segregating and suppressing the DC component from the signals obtained from the position detector.

Title: Air cooler with integrated pre-deduster and waste water treatment unit
Inventor: VITEK ROBERT DIPL ING
IPC: E21F3/00
Filed: 1981-10-14
Abstract: The air coolers used underground for cooling the mine air foul up after a relatively short period in operation, since the mine air is laden with dust which precipitates on the cooling tubes. By providing a pre-deduster upstream, a major part of the dust is precipitated. The spraying agent required for this purpose is kept low by circulating the spraying agent. The spraying agent is here first purified by means of a multi-hydrocyclone to such an extent that the overflow is available again as spraying agent. The underflow from the multi-hydrocyclone is aftertreated in a clarification tank with flocculants, and the overflow from the clarification tank can be used for other purposes or, under certain conditions, also re-used as spraying agent.
