Patent DE-3317598-A1 (DE)
Title: Rebedding device
Inventor: SAARINEN EERO
IPC: A61G7/14
Filed: 1983-05-14
Abstract: Rebedding of bed-ridden patients requires aids in order to relieve the nursing staff and to expose the patient to as little pain as possible. Conventional lifting devices have failed to prove their worth. Another conventional device essentially comprises a very large carrying cloth which, however, is bulky and not very pleasant for the patient. The rebedding device according to the invention comprises a handy, easily transportable transfer device by which a cloth, on which the patient is bedded, for example the bedlinen, can simply be drawn onto a couch standing beside the bed. The device can be operated by a nurse without difficulties, and the patient is always supported by the cloth during rebedding.

Inventor: DRESPA GERD
IPC: A24F1/28
Filed: 1983-06-10
Abstract: Ein papierloses Rauchen ist mit Hilfe einer Zigarettenspitze möglich, bei der in dem Gehäuse der Zigarettenspitze ein in das Mundstück übergehendes Saugrohr angeordnet ist, auf dem ein über eine sich gegen das Mundstück abstützende Druckfeder belastetes, verschiebbar angeordnetes und endseitig eine Schubscheibe tragendes Schubrohr geführt ist. Dieses Schubrohr mit der Schubscheibe wird bei entsprechend gleichmäßiger Entlastung der Druckfeder in die auf das Gehäuse aufschiebbare Hülse geschoben, so daß der darin befindliche Tabak kontinuierlich zum freien Ende hin vorgeschoben wird, wo der Abbrand wie bei Zigaretten bisher üblich entfernt werden kann. Nach dem völligen Aufrauchen des Tabaks und dem Ausdrücken des letzten Restes an Asche kann durch Zurückziehen des Schubrohres mit Hilfe eines Schiebers die Druckfeder wieder vorgespannt und die Hülse anschließend mit Tabak erneut gefüllt werden.

Title: Method for mixing a plurality of materials of different aggregate states
Inventor: SCHLADOFSKY LEOPOLD DIPL ING
IPC: B01F5/04
Filed: 1983-07-08
Abstract: In order to mix a plurality of materials of different aggregate states, particularly for preparing high-grade solids/liquid mixtures up to colloidal systems, the materials, suitably proportioned, are fed to an injector nozzle, which is actuated by compressed air and which has an annular compressed-air nozzle, an internal intake tube and an annular intake chamber. The mixture, which emerges from a mixing/outflow tube of the injector nozzle, is passed, so as to achieve an unpressurised offtake of the air used for actuating the injector nozzle, directly into an air expansion vessel having deflector bodies and collection devices for the solids/liquid mixture.

Title: Circuit arrangement for the starting and brightness control of fluorescent lamps
Inventor: LUDWIG JUERGEN DIPL ING
IPC: H05B41/04
Filed: 1983-07-28
Abstract: A circuit arrangement for the starting and brightness control (dimmer mode) of fluorescent lamps is intended to be designed to lead to a stable operation and reliable starting even in low environmental temperatures and, in particular, also to make possible a dimmer mode, even in the case of modern, power-saving, thin fluorescent tubes. For this purpose, an interrupter switch (9) is connected in series with the heating circuits (6) and hence in parallel with the fluorescent tube starting electrodes (5), which interrupter switch (9) can be driven from a phase shifter (depending on the desired operating brightness). In that the inductive heating current (i3 = i1) via the series connection of the heating circuits (6) and the switch (9), which is initially closed, is opened abruptly, a starting voltage (uZ) is set across the switch (9), and hence across the starting electrodes (5), which is very steep and very high, determined by the preceding heating current, and which leads to reliable starting and stable light operation in every light time interval (a) which is predetermined by the phase shifter (8) and even when the fluorescent tube (2) is at very low operating temperatures.

Abstract: Drum-type washing machine for domestic use, the laundry drum (2) of which is arranged rotatably in a tub (1) provided with a feed orifice (3). The laundry drum (2) is provided on its entire cylindrical surface with perforations for the passage of water or washing liquor. The drum-type washing machine is equipped with a pump (14) for conveying the washing liquor and the rinsing water and has a fresh-water inflow (11) and a washing-liquor and rinsing-water flow-off (17) following the pump (14). So that it is possible to wash with a minimum amount of water, there is provided underneath the tub (1) a heated water vessel (6) which is connected to the tub and to which the fresh-water inflow (8, 11) and a water flow-off (15) leading to the pump (14) are connected. The outlet line (16) of the pump (14) is divided into the washing-liquor and rinsing-water flow-off (27) and a wetting line (19) leading to the laundry drum (2) and having a valve (20).

Title: Hydraulic drive arrangement
Inventor: NIKOLAUS HEINRICH PROF DR ING
IPC: F04B49/00
Filed: 1984-02-09
Abstract: The invention relates to a hydraulic drive arrangement with a hydrostatic working machine with adjustable displacement volume, to which a hydrostatic tacho-generator is coupled. The adjusting cylinder of the working machine is actuated by a multi-way servo valve which can be adjusted depending upon a control pressure and in the opposite direction by a servo pressure. The control pressure is generated by the tacho-generator which provides a control flow corresponding to the actual speed value of the working machine and an adjustable throttle for the control flow. For the selection of the direction of rotation of the working machine, an individual adjustable throttle is provided for each direction of rotation and the hydraulic tacho-generator works in the closed circuit so that, in any direction of rotation, the delivered control flow is delivered back into the line by the tacho-generator via the adjustable throttle, from which line the control flow has been removed, that is to say either back to the tank or into a servo pressure line. The working machine can consequently work in both directions as a motor or a pump, that is to say in four-quadrant operation, energy losses in the control circuit being avoided. <IMAGE>

Title: Electronic ballast for fluorescent lamps
Inventor: MERTENS FERDINAND DIPL ING
IPC: H05B41/285
Filed: 1984-04-06
Abstract: Since the DC voltage of the DC voltage source (9) builds up only slowly after switching on, in the case of the electronic ballast, the push-pull switch arrangement (12, 13) is not activated until the DC voltage has reached a specific minimum value. As the DC voltage builds up, it charges an energy store (24) whose charging time constant is much shorter than the time constant of the build up in the DC voltage (Ug). When a threshold value is reached at the output (29) of the energy store (24), the switching element (30) (diac) switches on and switches the transistor (12) into the conductive state. The fluorescent lamp (19) is initially pre-heated by the oscillations of the operating tuned circuit (LC) and is then reliably started. Flickering during starting of the fluorescent lamp is prevented. <IMAGE>
