Title: Veneer pressed and bonded onto three=dimensionally fluted surface - by progressive moulding with tools then distributed pressure on pressing membrane
IPC: B30B5/02
Filed: 1980-03-22
Abstract: The parent patent describes a method of fitting a decorative facing, esp. a veneer, round a workpiece possessing throats or fluting; this decorative layer is placed, with adhesive beneath it, onto the workpiece, the laminated structure is then placed below a flexible membrane and shaping tools force the membrane and decorative coating into the flutings of the workpiece. The membrane is then pressurised, so that the bonded joint is formed by the adhesive and sets. In the patent of addition, the method is improved for use on a workpiece where flutings oriented in different directions or planes meet at a corner or intersection. In a first step the membrane and veneer are pressed by a single tool at the intersection, causing a bulge to form on either side of the tool; in the second step further tools are pressed down onto membrane and veneer to transform the bulges into a series of undulations. Finally, distributed pressure is applied to the membrane thus flattening the veneer onto the three-dimensional workpiece and forming the bonding. A neat fit of veneer onto a three-dimensionally shaped workpiece is obtained.

Title: Status signal to indicate overload condition - uses oscillator gated to drive display and alarm if overload occurs
Inventor: STROMBERG BERNHARD
IPC: H02H3/04
Filed: 1980-04-14
Abstract: A status monitoring facility for use with electronic control systems provides indication of any danger level caused by a short circuit or overload condition. The system uses an oscillator (7) that has tuned frequency to drive a light emitting diode (12). At the same time a buzzer may be activated as an additional alarm. If a short circuit occurs on the coupled load a voltage drop occurs (13,14) to switch a bistable (4) that in turn causes transistors (1,9,17) to switch of the load unit. A further bistable (5) switches and the buzzer (6) is activated and at the same time the oscillator (7) is gated to activate the diode (12) at the tuned frequency.

Patent DE-3106665-A1 (DE)
Title: Hydrodynamic coupling
Inventor: EISENMANN SIEGFRIED DIPL ING
IPC: F16D33/04
Filed: 1981-02-23
Abstract: The prior art contains hydrodynamic couplings which operate on the Föttinger principle and in which the pump impeller and the turbine rotor form an axially displaceable unit in a completely closed housing (- at the same time, however, the impeller and the rotor can be rotated relative to one another). The blades of the pump impeller are fixed to one end wall of the housing and project to a greater or lesser extent into the pump impeller depending on the axial position of the said unit, thereby determining the torque which can be transmitted. The invention provides a cup which rotates with the turbine rotor and into which this rotor is pushed when the pump impeller has been moved out of the region of the pump impeller blades. The coupling thus acts as an automatic coupling and is particularly suitable as a starting coupling for motor vehicles with a power-shift transmission.

Title: Process for generating an SO3-containing gas for exhaust gas purification in the electrostatic precipitator
Inventor: BODE HANS-JUERGEN
IPC: C01B17/76
Filed: 1981-03-07
Abstract: SO3-containing gas is admixed to a steam-containing exhaust gas prior to purification in an electrostatic precipitator in order to improve the separation efficiency of the filter. The SO3-containing gas is generated by combustion of sulphur, an SO2-rich combustion gas initially forming which is converted by catalytic oxidation of SO2 to give SO3. Cold air can be admixed to the combustion gas which leaves the furnace in order to keep the temperatures for the catalytic conversion in the range from about 370 to 500 DEG C. The control of the temperature of the combustion air fed to the furnace and/or the flow rate of the cold air admixed prior to the catalytic conversion is controlled by temperature measurement at the inlet or outlet of the catalytic conversion or else by the sulphur feed rate.

Filed: 1981-07-04
Abstract: An x-ray crystal spectrometer consists of a device for producing an electron beam for irradiating a sample and has a chamber for receiving a crystal, a proportional counter and a semiconductor detector for detecting x-rays. The crystal and the semiconductor detector are approximately within the same polychromatic radiation, so that the evaluation can be carried out with a multichannel analyser taking account of a single geometrical position of the sample with respect to the crystal or the semiconductor detector. All in all, this simplifies the analysis and improves the quantitative evaluation.
Patent DE-3132487-A1 (DE)
Title: Handle for tennis/squash rackets
Inventor: DEUS HANS-JUERGEN
IPC: A63B49/08
Filed: 1981-08-17
Abstract: In the previously known tennis and squash rackets, the centre line of the racket and lower arm forms an obtuse angle in the normal racket-holding position. As a result, the lower arm is loaded with each stroke by a changing torsion moment. This can lead to so-called "tennis elbow". Furthermore, the racket surface is not located parallel to the palm of the hand. The invention is based on the object of preventing changing torsion moments in that the centre line of the racket and lower arm forms a straight line. The drawing shows the achievement of the object. The resting surface of the handle for the central section of the small, ring and middle fingers forms an angle alpha of 137 +/- 10 DEG  relative to the centre line of the racket. Due to the depression for the index finger, the latter is in a semi-extended position and, in conjunction with the cams which engage between the finger projections and with the resting surface for the ball of the thumb, prevent twisting of the racket. The resting surface of the joints, metacarpal bone/proximal phalanx of the fingers, is located parallel to the racket surface. It is not necessary to change the grip for forehand and backhand strokes. <IMAGE>
