Title: Transducer for measuring and controlling laser beam wavelengths - uses prism through which beam can be directed at slightly different angles
Inventor: GRASSME WOLFGANG DIPL PHYS
IPC: G01J3/28
Filed: 1977-05-09
Abstract: The transducer is designed for producing a voltage output dependant on the wavelength of the light in a laser beam, for use in controlling the wavelengths produced by a laser, partic. for certain dyestuff a applications. A laser beam (1) is divided into two separate beams (7, 11) by a half silvered mirror (3) the position of which is adjustable. One half beam is fed via a mirror (8) and filter (9) to a photo multiplier (10) and the output of this can be used to hold the laser output intensity constant. The other half beam is fed through a spectrum separating prism and lens array (2) and thence via a filter (5) to a photosensitive plate (6). Together with the position of the first mirror (3), the output of this represents the wavelength of the laser beam.

Title: Pneumatic repair tool for dented body panel - applies vacuum suction to restore original panel shape
Inventor: KLEIN GERHARD DR
IPC: B21D26/02
Filed: 1977-06-16
Abstract: A hand tool (1) which is used to repair dented body panels on cars, is operated by vacuum. The tool has a hollow body (2) to which an external handle is attached (14). The contact side of the repair tool (1) has a sealing ring (4) which encircles the dented panel area (16). As a vacuum is applied to the hemispherical chamber on the tool, the resulting pulling force reverses the dent in the panel to its orignal shape. An interchangeable support plate (3) inside the body chamber, which has the correct curvature, ensures that the panel obtains the required shape.

Title: Cutting device for extruded clay blanks - has batch separator and blank cutter preventing sideways movement and deformation
Inventor: HAESSLER ANDREAS ING GRAD
IPC: B28B11/16
Filed: 1977-07-05
Abstract: The extruded lengths cut are cut further into blanks in the extrusion direction. At least two cutting movements are used. The blanks are moved by a pushing arrangement through the blank separator cutter. The blanks and waste ends cut form total length which corresponds to given blank row length on the blamk supports. The gap formed in row after removal of waste end coincides with the changeover instant and space needed for moving of different rows. The cutting can deal wiht small extruded cross sections. Accurate cut lengths can be ensured also when several strands are simultaneously extruded.

This still residue is then rectified at a still temp. of 52-60 degrees C to obtain highly pure ethylene; the still residue is further rectified to obtain ethane and the residue obtd. rectified again to obtain highly pure propylene. Sepn. of thje ethylene, ethane and propylene is effected in separate rectifying columns. A suitable plant is described. Economy in energy and cost is achieved; no compressors are needed. Ethylene and proplene are obtd. in purities of up to 99.9 vol. %.

Title: Reinforced ribbed belt mfr. - by pressing a belt blank against a grooved drum and vulcanising it in that position
Inventor: RICHMOND KENNETH D
IPC: B29D29/10
Filed: 1979-02-13
Abstract: An endless power transmission belt, of the type having a central reinforcing layer between an outer tension layer and an inner compression layer having longitudinal ribs, is made by tensioning a green belt strip over a grooved heated vulcanising drum, pressing the tensioned strip onto the drum to cause the inner layer of the strip to mould into the grooves, and finally curing the strip so moulded. The curing step is pref. effected whilest the strip is still under tension and compression upon the drum. Sufficient rubber is employed in making belt sleeve to fill groove roller during forming so that load-carrying cord is continuous across sleeve. Cord is not cut into individual belt widths or compressed into belt-body which would result in distortion.

Title: Wind current compression air turbine - has double wheel drive actuated by increased compression to produce energy
Inventor: SCHNEIDER SEN NIKOLAUS
IPC: F03D3/02
Filed: 1979-06-13
Abstract: The turbine has two drive wheels mounted on separate drive shafts, these shafts driving by suitable couplings, two generators for producing current. The prevailing wind drives the wheels by impingement producing an increased pressure and driving wheel (N1) in one direction and driving wheel (N2) in the other with increased power. An air funnel ensures the exact flow of wind into the turbine and strengthens the drive on turbine wheel (N1). The swallow-tail at the rear of the turbines regulates the direction of the whole ensuring that the air funnel always faces the wind direction. The machine can be constructed in any size and is particularly successful in hill and mountainous regions.

Title: Electromagnetic material testing by self-stimulated oscillation - using coil, e.g. commercial magnetic head, with low coercivity core
Inventor: LAMBECK MARTIN PROF DR ING
IPC: G01N27/90
Filed: 1979-07-20
Abstract: The electromagnetic material test method involves a coil producing self-stimulating oscillations in combination with an amplifier. It uses a coil with a core which is smaller than the coreless coil used in DE2919983. This does not require other changes in circuit components. The core is a cylindrical coil core with its base placed on the object or a U-shaped core or used in a line transformer, with an air gap in which the test object is placed. Alternatively, the coil is a commercial magnetic head as found in commercial audio or video equipment in whose air gap the test specimen is arranged. The core material is of high initial permeability, low coercive field strength and low conductivity.
