Patent DE-3818945-A1 (DE)
Title: Delivery-flow control device for hydrostatic transmissions
Inventor: RAABE ULRICH
IPC: F16H61/46
Filed: 1988-06-03
Abstract: Delivery-flow control device for hydrostatic transmissions with delivery-flow cut-off to ensure an optimum energy saving and an associated reduction in the heating of the fluid, especially when used in motor-driven grabs. In accordance with the object, a delivery-flow control device with delivery-flow cut-off is designed in such a way that when an adjustable operating pressure is exceeded the delivery flow is, without an additional control pulse, set virtually to zero and that the operating pressure rises again when there is an undershoot. This regulation is achieved by virtue of the fact that the regulating spring acting counter to the regulating piston is supported on an axially displaceable abutment on which the operating pressure of the fluid acts via a control line. Fig. 1 shows the delivery-flow control device with hydraulic pressure-dependent delivery-flow cut-off. <IMAGE>

Title: Reactor for purifying industrial exhaust gases
Inventor: PRIEFER NORBERT
IPC: B01D46/34
Filed: 1988-09-09
Abstract: In a reactor for purifying industrial exhaust gases, at least one vertical row (6) of roof-shaped metal sheets (5) is provided, over which sorption granules (16) migrate. In order to improve the contact between the sorption granules (16) and the untreated gas, one vertical slot space (9, 10) each is formed on both sides in addition to the vertical row (6), which slot space is covered by means of baffles (13) against the entry of granules. The baffles (13) form filter surfaces (25) of the sorption granules (16) for the untreated gas. The untreated gas enters into the slot spaces (9, 10). Pure gas exits through orifices (8) of the spaces (7) on one side beneath the roof-shaped metal sheets (5). <IMAGE>

Abstract: A videophone has at least a telephone set, an image recorder and a video playback machine. This videophone allows pictures to be taken from one or several persons located in front of the telephone set, as well as from documents, in the most simple manner. For that purpose, images of documents (8) that can be set on a support (10) arranged underneath the screen (9) can be recorded and transmitted by unfolding a mirror (6) in front of the lens (7) of the camera (3). A very compact videophone is thus obtained, since the video playback (2), the image recorder (3) and a control monitor (4) for the images taken by the image recorder (3) and transmitted through the telephone lines can be all integrated in a housing (5).

Title: Circuit arrangement for switch-on (making) current limitation
Inventor: PUETHE HERMANN DIPL ING
IPC: H02H9/00
Filed: 1989-02-09
Abstract: A circuit arrangement is provided for limiting the switch-on current of modules (assemblies), which circuit arrangement is intended, in particular, to prevent interference through supply voltage dips when switching on (plugging in) such modules during operation. A MOS field-effect transistor (V12) is connected in parallel to a current-limiting resistor (R11) arranged in the supply voltage cable, which transistor provides low-ohmic bypass of the current-limiting resistor when the voltage drop across this resistor after extensive discharge of the module capacitors (CE) has fallen below a predetermined value and can no longer be used for switching through a first control transistor (V10) which short-circuits the gate-source path of the MOS field-effect transistor (V12). A second control transistor (V8) short-circuits the control path of the first control transistor (V10) after connection through of the MOS field-effect transistor and prevents switching-off of the MOS field-effect transistor in the event of brief current pulses. These pulses are limited by an additional identical but dynamically effective switch (R20, V21). By means of an optocoupler (optical isolator) (U9), intefering non-capacitive loads can be switched off during the current-limitation phase. <IMAGE>

Title: Appts. for filtering liquids - by flowing upwards through moving particulate filter bed, then re-directed to parallel filter when certain differential pressure is reached
Inventor: REUTER ROLF
IPC: B01D35/12
Filed: 1989-05-18
Abstract: The filter material is in the form of a circulating layer in a filter vessel through which the liquid to be filtered flows from below. The pressure in the vessel is monitored and when a certain pressure is reached the liquid flow is re-directed to a second parallel filter vessel. The turbidity of the liquid at the filter outlet is measured, and the filter vessels are  exchanged when a set value is reached. The filter vessels are back-washed until the turbidity of the liquid outlet falls below a certain value. A retaining device is provided near the outlet end of the vessels and a permeable floor at the inlet end, and the filter material is placed between these two elements. The vessels are vertical cylinders in shape with  conical lower sections. USE/ADVANTAGE - used in the design of filters using a particulate filter material such as activated carbon,  kieselguhr, or fibrous materials such as paper or cellulose. The proposed arrangement provides extended periods of operation even when particles which tend to coagulate are used requires no separate dosing system, can work under pressure and exposes the operating personnel to no hazardous situations.

Title: Adjustable lifting beam for containers - has shear member to limit force transmitted to hydraulic cylinders of adjusting mechanism
Inventor: KAUP OTMAR
IPC: B66C1/10
Filed: 1989-11-16
Abstract: The lifting beam has a middle section from each end of which extend telescopic sections having cross-beams engaging with the upper corners of the container. The beam is adjusted to suit different sizes of containers by hydraulic cylinders with rods pushing outwards from the middle section. If during movement of the container excessive force is transmitted to the cylinder by, e.g., contact with another container the cylinder can easily be damaged. To prevent damage occurring the piston rod (9) is fastened to the beam bracket (10) with a flanged shear bush (22,23) interposed. The shear bush has a groove (26) in the flange face which allows the cylindrical part (22) to shear from the flange (23) if a limiting force is exceeded, so that the rod (9) can pass through the bracket and damage to the cylinder unit is avoided. USE/ADVANTAGE - Reduced maintenance costs and downtime for adjustable lifting beam for containers.
