Title: Process for the fine machining of gearwheels with a gearwheel-shaped tool, especially shaving cutter
Inventor: SCHAPP UDO DR ING
IPC: B23F19/00
Filed: 1984-11-10
Abstract: What is proposed is a process for the fine machining of gearwheels with a gearwheel-shaped tool, with crossed axes of the tool and workpiece, especially for gearwheel shaving, with a depth feed taking place by the plunge method and with a return stroke, and with a tangential feed of the tool relative to the workpiece taking place in between by the underpass or diagonal method. To achieve satisfactory machining results, the initially straight tooth flanks of the workpiece are to be maintained during the depth feed and a desired crowning be produced only during the tangential feed. For this purpose, a crossing angle of the axes, at which the process takes place, and if appropriate the diagonal angle must meet specific requirements.

Title: Linear interference position scanner
Inventor: JEHLICKA BOHUMIR
IPC: G01B9/02
Filed: 1984-11-28
Abstract: In the scanner, laser light is split by a splitter prism into a reference beam and a measurement beam, which falls onto a movable angular reflector and, after reflection, returns with a parallel displacement into the splitter prism, where it interferes with the reference beam, which is inclined relative to the measurement beam in such a manner that as a result of the interference a system of numerous fringes is created, into which system a phase mask is inserted, which has the form of a grating and exhibits lines which are parallel to the interference fringes and which exhibit the same density, this grating being split up into two or four fields, the lines of which are mutually displaced by 0, 1/2, and 3/2 line widths, and light-sensitive elements being fitted behind these fields. The entire system is encapsulated in a semi-enclosed hollow profile with an independent guide, the connection to the outer element to be measured being implemented by means of a swivel joint.

Title: Arrangement for digital division of an input cycle
Inventor: JENSEN PETER G
IPC: H03K23/66
Filed: 1985-06-13
Abstract: To implement an arbitrary division factor, set values for a counter which can be preset therewith and which is reset step by step by the input cycle to be divided, are stored in a table (T). Each time the initial setting is reached, a pulse of the output cycle occurs. At the same time, by appropriate addressing of the next memory position in the table, the set value held there for the counter (ET) is made ready and set. The process alternates between at least two set values, in different sequences. After a certain number of set values, the address sequence is repeated. This number corresponds to the lowest possible denominator of the fraction which represents the ratio of the input cycle to the output cycle with sufficiently close approximation. <IMAGE>
Patent DE-3521420-A1 (DE)
Title: Device for trimming the rig
Inventor: DEUTSCHER OSWALD DR ING
IPC: B63B35/79
Filed: 1985-06-14
Abstract: The invention relates to a device for trimming the rig in sailing boats and in particular in sailboards. The pulley blocks normally used when setting the stretchers take up too much space for smaller sailing boats, in particular in sailboards, and in addition also endanger the yachtsman or surfer. In order to avoid both these factors and likewise eliminate damage to the mast or boom by fastening additional accessories, the invention provides for the releasable connection of a curved shell on the mast or boom, in which the axis of curvature lies parallel to the mast or boom axis. Leading off from this shell in a radial direction is a pivot for a hand lever to which a directional clamp is fastened through which a trimming sheet adjoining the stretcher runs. By actuation of the hand lever, a considerable trimming force can be applied and passed virtually directly into the stretcher. If this is done for preparation on land, as in windsurfing, the tool can be left behind on the beach without endangering the surfer during sailing.
Patent DE-3523163-A1 (DE)
Inventor: GROETZINGER LOTHAR
IPC: B30B15/16
Filed: 1985-06-28
Abstract: The pressure-adjusting system for controlling and damping the starting and braking operations, which is adapted to the requirements of press operation by means of an electric control system (37, 38, 39) according to the travel, time or angle, prevents at each cycle restrictions in the feed line (3) between the safety valve (4) of the press and the actuation cylinder (5) and allows an optimum pressure pattern by a parallel line (15) which is inserted therein, through which, depending on the setting position of a distribution valve (23) fitted inside, the pressure can be decreased or increased to a pre-selected degree without a considerable loss of time. A pressure-maintaining system, which is itself independent of the position of the safety valve of the press together with a storage unit (19) and topping-up system permits not only the pressure relief to the tank (1), but also the additional pressure or a removal from the supply line (3) directly after the switching over of the magnetic setting elements (31, 33, 35) controlling the valves (4, 23), which are triggered by signal emitters (39), which mark the various partial strokes of the press.

Patent DE-3542599-A1 (DE)
Title: Process and apparatus for eliminating sparingly water-soluble and readily volatile impurities from an exhaust air stream or exhaust gas stream by biological oxidation
Inventor: BAEUERLE ULRICH DIPL ING
IPC: B01D53/22
Filed: 1985-12-03
Abstract: In addition to physicochemical methods for exhaust air purification, two biological processes - bioscrubbers and biofilters - are also known. These processes are characterised by a particularly inexpensive and environmentally friendly mode of operation. However, the efficiency of these biological exhaust air purification processes decreases markedly if the exhaust air to be purified contains sparingly water-soluble or readily volatile compounds, for example xylene or dichloromethane. The invention depicted in Fig. 1 is able to feed even such sparingly water-soluble or readily volatile substances to a microbial degradation. A chemically and biologically inert membrane serves as a mediator, to which the exhaust air constituents are first sorbed. They then migrate through this membrane and are biologically degraded on the other side by microorganisms, which are located there in an aqueous nutrient solution, or directly colonise the membrane surface.   As a result of this invention, the area of application of the biological exhaust air purification process is highly significantly expanded, since these same sparingly water-soluble or readily volatile substances are frequently used as industrial solvents.

The air bag is folded to form an air hose and the two opposite air hose ends which project over a gas generator are in each case guided along the inside wall and the floor of a container to the outside wall of the container and from thence are placed at a container packing level and back, so that the folded layers extend from the outside wall to the inside wall of the container.
Patent DE-3604313-A1 (DE)
Title: Power semiconductor module
Inventor: BAYERER REINHOLD DIPL ING DR
IPC: H01L23/495
Filed: 1986-02-12
Abstract: The invention proposes that external connections, for example control connections (13) and especially so-called externally located connections, be provided with a plug connection (10, 12). In consequence it is not possible to insert connecting elements (11) for external connections (13) into a housing (1) until a fitted and soldered substrate (2) has been inserted. As an alternative to this modular design, it is proposed to solder connecting elements (11) into the housing (1) at a relatively low soldering temperature, in a second soldering step, after the substrate (2) has been bonded in. <IMAGE>

Title: Control circuit for the magnet coil of an electromagnet
Inventor: STIGLMAYR ROLAND DIPL ING
IPC: H01F7/18
Filed: 1986-07-15
Abstract: Two solutions for a control circuit are described which allow a predetermined attraction force to be produced using an electromagnet which is of small construction and does not produce this attraction force at its rated voltage. A first solution comprises the operating voltage, which is equal to the rated voltage of the magnet coil at a load factor of 100 %, being raised to a considerably higher value during the attraction time, by means of a connected inductance and a charge capacitor (Figure 1). A second solution comprises reducing an operating voltage, which is significantly above the rated voltage of the magnet coil, to a value corresponding to the rated voltage of the magnet coil, after the attraction time, by periodic interruption using the inductance of the magnet coil as an energy store.

Patent DE-3710443-A1 (DE)
Inventor: JAENSCH MANFRED
IPC: G01M3/32
Filed: 1987-03-30
Abstract: In a method of testing the gas-tightness of walls defining a closed chamber a hollow member of resiliently flexible material is inserted into the chamber. A liquid is introduced into the hollow member until the hollow member substantially fills the chamber. A test gas is then introduced into the space defined between the hollow member and the chamber walls. Escape of any test gas from the chamber is then sensed by loss of gas pressure in the chamber or the presence of test gas outside the chamber. The presence of the liquid-filled hollow member reduces the amount of test gas needed and the associated risks and cost. The chamber may be defined between segments of oil well pipe casing connected by threaded sockets or it may be the space within a tank.
