Title: Woodworking machine for the tenoning and longitudinal-profiling of wooden frame members
Inventor: HAENSLER GEORG
IPC: B27M3/18
Filed: 1981-10-17
Abstract: The invention relates to a woodworking machine for the tenoning and longitudinal-profiling of wooden frame members, in particular of wooden frame members for window frames, consisting of a work table with stand, on which a plurality of vertical spindles with cutting tools for tenoning and mortising or longitudinal-profiling are arranged. The essential feature of the novel woodworking machine lies in the fact that the table top (2) of the work table is of octagonal design and each of the eight table sides has a workplace (5-12) with a tool spindle (21-28). This makes it possible to perform a different operation on the wooden frame members on each table side, so that virtually all working possibilities required in window-frame production are provided on a single work table. Furthermore, the work table has a stationary vertical central column (13). The work table can be pivoted, as desired, by an adjusting motor (19) about this central column (13), for which purpose it is supported by supporting wheels (20) on the floor (13). The individual tool spindles are provided, besides their two normal bearings (29, 30) in their upper ends (24a), with an additional further bearing arrangement (33) which is seated on a pivoting arm (34) supported on the central column (13). This ensures quiet running of the spindle even at high speed. <IMAGE>
Patent DE-3143677-A1 (DE)
Title: Memory circuit
Inventor: FREITAS MARIA LUCIA CIRSTOVAO
IPC: G08B13/00
Filed: 1981-11-04
Abstract: Storing the position of a mechanical contact (K) by a circuit arrangement is performed by a PNP transistor and an NPN transistor, which turn on when the contact (K) is opened. In this case, the memory circuit is independent of the supply arrangement within wide ranges, because two series-connected diodes (D1, D2) always generate a voltage of at least 1.4 V, which is sufficient for turning on the NPN transistor (T2). In addition, the setting delay of the memory circuit can be set by a timing element (R4, R5, C1). The contact (K) may be substituted by a filter circuit, comprising coil (L1), capacitor (C2) and piezoelectric crystal (KR). <IMAGE>
Patent DE-3145259-A1 (DE)
Title: Sack, preferably made of plastic film, which can be used as a packaging means for bulk materials
Inventor: BUESCHERHOFF BERND
IPC: B65D30/24
Filed: 1981-11-14
Abstract: The invention relates to a sack, made of material which is impermeable to air, preferably plastic film, which can be used as a packaging means for bulk materials, in particular fine-grain and powdery bulk materials. In sacks made of material which is impermeable to air, there is the problem that the conveying air used when the sack is filled with powdery or fine-grain materials cannot escape. The sacks remain inflated like a balloon, such that no firm stable piles can be formed from filled sacks. It is known to form holes in the sack covers, from which the air can escape. In this case, it is disadvantageous that materials can also escape from the holes. Additionally, moisture can penetrate into the material through the holes, which poses problems in the case of moisture-sensitive salts, for example fertilisers. According to the invention, air-permeable regions, for example holes or slots in the sack cover, are covered at least on one side by a filtering material. The filtering material allows the air to escape from the sack without the material being able to escape with it. The regions covered by filtering material can be arranged in the sack in such a way that the material is also optimally protected against moisture.

Title: Synchronous machine control via a split machine model
Inventor: GRUMBRECHT PETER DIPL ING
IPC: H02P25/02
Filed: 1981-12-11
Abstract: For a method for controlling a synchronous machine, which can be operated from the mains via a controllable converter, according to Patent... (Patent Application P 3045032.9), the object exists of finding an arrangement in which modules which can be matched better can be used by implementing the non-inverse relationships. This object is achieved in that the rotor-oriented inverse submodel (2) consists of a non-inverse machine model in a first part (L1) with the input variables iF, iSd, iSq and the output variables  psi hdx and psi hq, in that furthermore, in a second part (L2) the variable delta  and a control value  psi hqw are determined from the values psi h and  psi hq on the basis of the relationships in the right-angled triangle, and in that this machine model is located in the feedback of a control variable regulator R for the field current iF to which the control variable  psi hdw and the value  psi hdx are supplied. <IMAGE>
Patent DE-3150976-A1 (DE)
Title: Pneumatically driven double diaphragm pump
Inventor: BUDDE DIRK DIPL ING
IPC: F04B43/073
Filed: 1981-12-23
Abstract: A double diaphragm pump with a novel compressed air reversing device is described, on which a mechanical energy storage device is assigned to a valve control piston in order to reverse the compressed air fed to the two air chambers of the diaphragm pump, which storage device mechanically drives the control piston at the reversal point in such a way that the valve is rapidly reversed by the stored mechanical energy even in very slow pump operation, so that undefined intermediate positions with possible compressed air losses cannot occur. By virtue of this measure, in conjunction with new types of sealing devices for the movable parts, the pressure losses are reduced and the efficiency of the pump thereby increased, whilst also avoiding the need, in particular, for lubricating devices.

Title: Retroactively attached water guide on facades
Inventor: DARTSCH BERNHARD DIPL ING
IPC: E04B1/70
Filed: 1982-01-09
Abstract: To avoid an uncontrolled flow of water over facade surfaces - in particular over smooth concrete and plastered faces - in the case of rain and the ensuing undesired formation of stripes and streaks, suitable profiles are retroactively attached to the facades. These profiles preferably serve as drip edges and for water guidance and use the physical properties of water (surface tension etc). The precise position of the profiles is set, depending on the object, in harmony with the architecture of the building. <IMAGE>

Title: Clamping head of a metal sheet stretcher with a centring device
Inventor: KUTZ HEINRICH
IPC: B21D25/04
Filed: 1982-02-20
Abstract: A clamping head of a metal sheet stretcher is equipped with a centring device which serves to centre a metal sheet to be stretched in the clamping head before the clamping and stretching operation. The centring device comprises two centring arms, the edges of which move against the longitudinal sides of the sheets and which are displaced synchronously in opposite directions at right angles to the stretching axis. Since the sheets require a certain entry depth into the clamping heads, depending on the sheet thickness, in order to be clamped in an optimum way with the minimum waste, it was hitherto necessary for a second operative to guide the control operative accordingly. To provide optimisation and automation, guide bars with drivers sliding on the latter are provided on the centring arms parallel to the stretching axis. At the head, the said drivers have hook-shaped stops against which the end face of the sheet presses in the course of the insertion operation. A displacement measuring device is provided on the centring arm, the said device having a cable drum and a potentiometer on the same shaft. The end of the cable is secured on the driver. It is thereby possible to measure and control the insertion path via the potentiometer.

Title: Increasing the strength characteristics of metal and plastics sheets and bodies
Inventor: ROZSA GYOERGY DIPL ING
IPC: C21D7/00
Filed: 1982-07-20
Abstract: According to the invention, on the one hand, when manufacturing metal or plastics sheets by rolling, impressions are stamped into these sheets, which are produced by elevations on the surface of one of the rollers of a roller pair, it being possible for the elevations to have a variety of shapes: flat prisms, pyramids or truncated cones arranged in row or honeycomb form; grooves with semicircular or sinusoidal cross-sectional profile. Correspondingly, in other processes (compression moulding; mould casting, diecasting or centrifugal casting; deep drawing; blow moulding; stretching) the described elevations are applied to the inner surfaces of the top dies, bottom dies, stamps, patterns, moulds, casting dies or on the cores used, with the impressions resulting in negative form in the sheets or bodies produced. With the aid of exemplary calculations it is illustrated that sheets and bodies stamped according to the invention achieve:   - an increase in the strength characteristics (moment of inertia and section modulus) for the same volume, - a reduction in the material volume for the same moment of inertia and section modulus. There is thus the possibility of ensuring the same strength characteristics with a lower material consumption. t

Title: Novel toothbrush shapes: brushes lying transverse to the handle (transverse brushes)
Inventor: MEHEMDI HUSSAIN DIPL ING
IPC: A46B7/02
Filed: 1982-08-03
Abstract: Intensive brushing of the teeth is made possible by the brush lying transverse to the handle, especially since the bristles can better penetrate the interdental gaps during the longitudinal movement of the brush relative to the tooth and remove food remnants. The arched brush shape is adapted to the arched shape of the jaw, especially from the inside, and thus guarantees removal or prevention of a brown discoloration of the teeth caused by tartar, consumption of beverages, smoking and the like. In addition, the rotatable arrangement of the brush relative to the handle, with three engagement positions, enables the brush to be used for transverse and longitudinal movements relative to the teeth.

Title: Diaphragm for optical systems or devices
Inventor: DOST WILLIBALD
IPC: G03B9/02
Filed: 1982-10-07
Abstract: The invention relates to a diaphragm with a diaphragm aperture which can be adjusted in stages. For this purpose, the diaphragm comprises a liquid crystal element (1) with a central, circular flat element (3) and concentric circular rings (4, 5) which can be individually electrically activated and which allow light to pass through when a control signal is applied. Through activation or de-activation of the flat element (3) and the circular rings (4, 5), the diaphragm aperture can thus be adjusted in stages. An electrically controllable aperture diaphragm is thus obtained, which is resistant to mechanical stresses (e.g. shocks) and which requires only a low electric control power. The electro-optical diaphragm according to the invention is suitable for use as an aperture diaphragm for radiation limitation in optical systems, e.g. for adjustment of the beam divergence of the receiver of a laser range finder. <IMAGE>

Title: Composite drive for switching elements or actuation elements
Inventor: HAEUSSERMANN GERHARD DIPL ING
IPC: G05G9/047
Filed: 1982-10-14
Abstract: A composite drive for actuating at least two mutually independent switching elements or actuation elements, which has a hand lever which can be swivelled about two axes which intersect and engages at one end with two slides which can be displaced in planes which are parallel to one another in directions which are perpendicular to one another, said slides themselves being operatively connected to at least one switching element or actuation element in each case, is given a particularly simple and space-saving design by providing the slides (13,14) in each case with at least one linear switching path (42,43,44,50) which extends in their displacement direction and interacts with a switching element or actuation element (46 and 52, respectively). In this arrangement, the switching paths can be constructed in particular as cam paths (42,43,44) against which the sensing element (45) of a microswitch (46) rests, whilst other switching paths serve to generate a signal which is characteristic of the momentary position of the hand lever (3). In this arrangement, known analog and digital signal generators can be used. For example, a toothed rod (50) can serve as the switching path with which a toothed wheel (53) arranged on the shaft of a potentiometer (52) engages (Fig. 5). <IMAGE>
Patent DE-3239872-A1 (DE)
Title: Encapsulation composition for electronic components
Inventor: HEIDEGGER PETER DR RER NAT
IPC: C08K3/22
Filed: 1982-10-27
Abstract: Electronic components, in particular semiconductor components, must withstand changes in temperature of, for example, -60 DEG C to +150 DEG C. Conventional encapsulation compositions (embedding compositions) tend to crack during these temperature variations. In order to avoid cracks, a flexible encapsulation composition is used whose resin contains epoxidised cyclohexane rings, each carrying a methyl group. The bond between each pair of rings is formed by a single ester group. Quartz (silica) powder and, for example, aluminium hydroxide powder are added, as fillers, to this resin.

Title: Temperature regulation system for central heating systems
Inventor: LEVEN DIETRICH DR ING
IPC: F24D19/10
Filed: 1982-07-21
Abstract: The invention includes processes and devices which allow the central reversal of thermostat valves on room radiators between two preselectable temperature levels (regulating levels). In this connection, the central control signal as well as the necessary reversal energy is transmitted via the heating medium by selection of the forward run temperature. Therefore, no additional connections between central control unit and the thermostat valves are necessary.   For the functioning and the design of the reversible thermostat valves, various solutions are indicated, which can be implemented both with commercially available thermostat valves in association with special valve combinations and with commercially available thermostat valves in association with special preheating elements.

IPC: B62M1/24
Filed: 1983-01-10
Abstract: The tread levers (14) only carry out swinging movements, which is correspondingly also the case for: the cable pulleys 1, 2, 3, 4, 5, 6, the shafts 7, 8, the axle 9, the belts 10, 11, 12, 13, the lamellar levers 15, the switching rods 16 and the lamellar frames 17. The lamellas 18 serve as slider elements (Fig. 3) and are drawn through the water by lamellar frames 17 in the direction : vehicle front - rear in slider position. When returning in the direction : vehicle rear - front, the lamellas 18 fit tightly against the lamellar frame 17 (Fig. 4). The lamellar frames 17 swing in opposite directions in order to obtain a continuous slider effect of the lamellas 18. The lamellar system can also be driven by motors or rotors. For this purpose, the lamellas 18 are mounted on crawler tracks or the like in a non-foldable rigid fashion. The crawler track system in accordance with my patent application of 15.3.1980 - P 3010046.0 for infinitely variable transmissions with lever drive for bicycles could also be used for the manual drive. The entire surface of tread levers (Fig. 6) can be used as a pedal so that during the pedalling process the racing cyclist can set his feet on the tread levers 14 at the positions which are most convenient for him in each case. <IMAGE>
