Patent DE-3048344-A1 (DE)
Title: Vertical swivelling venetian blind slats electric motor drive - has central shaft through hole in epicyclic gear providing extra translatory movement
Inventor: TIPPMANN HEINRICH
IPC: E06B9/36
Filed: 1980-12-20
Abstract: Provision separate from swivel drive is made for horizontally sliding slits, with transition from one form of movement automatically controlled. A reversable intermediate member connects the motor as appropriate to sliding components or to swivel spindle, in a venetian blind with vertical swivelling and sliding slats . Here additional translatory movement into slow motion for activation of the swivelling spindle (18) is brought about via epicyclic gearing (78,79,81). The central shaft (72) is led through a hole in the centre of this, so that drive from the motor (1) and the two down-drives are coaxial with each other. The intermediate member may be activated by an electromagnet; or mechanically by lever and bolt. Drive is compact enough for building into a confined space.

Title: Panic lock device - has lever disengaged using electromagnet to temporarily eliminate panic function
Inventor: HINZ MANFRED ING GRAD
IPC: E05B47/06
Filed: 1980-08-26
Abstract: The panic lock has a catch (31) and a bolt (29) locked by a linking mechanism. The mechanism comprises a collar (28), an arm (28') and a panic lever (26). The panic lever can slide and is acted on by the armature (25) of an electromagnet (20'). The armature is spring loaded (21') and moves the panic lever into and out of contact with the linking mechanism's arm. The armature acts as a coupling slide that keeps the panic lever engaged with the arm when the electromagnet is not excited. When the electromagnet is excited, the slide disengages the lever from the arm. The advantage lies in being able to temporarily put the lock's panic function out of operation in a simple manner.

Title: Hydraulic switching arrangement for lopping machines
Inventor: BERTHOLD RAINER
IPC: A01G23/097
Filed: 1981-03-30
Abstract: The invention relates to a hydraulic switching arrangement for lopping machines and units, the movable lopping cutters of which are pressed on the tree trunk by hydraulic working cylinders. The aim of the invention is, while maintaining a good lopping quality, to lower the drive power required for the lopping procedure. It is the object of the invention to lower the advancement force required for pulling the tree trunk through the cutter system in that the contact-pressure force of the lopping cutters in the branch-free trunk regions is to be lower than in the case of direct cut-off of the branches, it being intended to achieve, at the same time, a mutually independent adjustability of the two contact-pressure-force stages. This is achieved in that a pressure control valve and a non-return valve, connected in parallel thereto, are arranged in the discharge line of the hydraulic working cylinders coupled to the movable lopping cutters. <IMAGE>

IPC: G03G21/10
Filed: 1981-05-25
Abstract: A toner recovery device is specified which is provided with a filter, which is arranged in the track of toner gathered from an image carrier, and with a device which is used to exert through the filter onto the gathered toner a force which causes the gathered toner to pass through the filter, as well as to exert a force which causes the gathered toner to move along the filter.

Title: Air-suspension classifier
Inventor: RAATZ WINFRIED DIPL ING
IPC: B07B7/083
Filed: 1981-07-01
Abstract: The invention relates to an air-suspension classifier with a bar cage having a vertical axis, for separating solid particles contained in a gas stream into coarse and fine fractions. The aim and object of the invention are, by means of a different arrangement of the bars on the rotary body (bar cage), to improve the screening effect and the throughput capacity of the air-suspension classifier with the same, or reduced, energy consumption. This object is achieved by the fact that the bars of the bar cage, diverging upwardly with respect to the axis of rotation, are arranged inclined in the direction of rotation or are designed curved along the circumferential line of the bar cage.

Title: Hydraulic buffer
Inventor: BITTEL KARL DR-ING
IPC: F16F9/44
Filed: 1981-11-26
Abstract: The invention relates to a hydraulic buffer for the acceptance of relatively large shock loads. In this arrangement, a new kind of valve is used for damping. The invention is intended to achieve minimum dimensions of the hydraulic buffer for a maximum damping force or work absorption, in order thereby to reduce the costs for materials and manufacture and obtain short overall lengths. It is the object of the invention to employ a considerably increased pressure for the damping force by reducing the pressure required for the return force. This is achieved by connecting the working space of the hydraulic buffer to the compensating space of the hydraulic buffer via a pressure relief valve designed as a liquid spring.

Patent DE-3209562-A1 (DE)
Inventor: SCHLENK MANFRED DIPL ING
IPC: G01R19/145
Filed: 1982-03-16
Abstract: A circuit arrangement detects and stores power line faults. The occurrence of sporadic faults as represented, for example, by inadmissibly long network collapses, which could lead to shut-down of a current supply and, therefore, to downtime of a computer are generally difficult to detect because the faults disappear given a return of the network, as does, therefore, the prerequisite for detecting the cause of such faults. For the purpose of detecting the cause of the fault, the rectified power line voltage is supplied to a comparison circuit followed by a signal circuit. The signal circuit is connected to a memory which influences a display. As a result, power line faults remain stored despite the return of the power line input voltage. The circuit arrangement is particularly suitable for use in power supply systems for data processing devices.
