Title: Method for producing a linear Fresnel lens and/or a Fresnel lens matrix, and device for carrying out the method
Inventor: NAWRATH PETER
IPC: B29D11/00
Filed: 1981-04-11
Abstract: In this method for producing a linear Fresnel lens, the workpiece to be machined is held on a support which can be moved in a revolving fashion about an axis of rotation. The plate-shaped workpiece is guided at least partially in each case parallel to the axis of rotation of the support, and in order to produce the refractive surfaces of the Fresnel lens the forming tool is moved in a displacement movement which is parallel to the axis of rotation. The device for carrying out the method comprises a workpiece holder which either is constructed as a hollow cylinder or is configured in the shape of a band, the workpiece being arranged on the lateral surfaces of the support. In this case, the forming tool can be displaced parallel to the lateral surface of the revolving body in order to produce the refractive surfaces. Fresnel lenses can be produced in a cost effective manner using the method and the device. In addition, the individual refractive surfaces can also be machined more cleanly than in the case of previously known Fresnel lenses.

Title: Centrifugally operated freewheel device
Inventor: ROITZHEIM ARNO
IPC: F16D43/16
Filed: 1981-07-08
Abstract: The purpose of this device is to connect two components or rotating bodies, such as the flywheel and clutch bell of a centrifugal clutch, in one direction of rotation until centrifugal forces on one of these components, in this case on the flywheel of a centrifugal clutch, occur. The engine of a vehicle which has a centrifugal clutch with a centrifugally operated freewheel device can be started simply by pushing the vehicle. For as long as the flywheel of the clutch is rotating, there is no connection between it and the clutch bell, and the clutch shoes of the centrifugal clutch represent the only power transmitting elements. The application of the device is, however, not restricted solely to a centrifugal clutch. The construction of a centrifugal clutch with a centrifugally operated free wheel device is illustrated in an exemplary embodiment shown in Figs. 1 and 2, Fig. 2 showing the shoes (component 7) being pressed against the outer rim of the flywheel (component 5) by the centrifugal force. <IMAGE>

Abstract: A valve rotation device, by means of which the valve disc is rotated uniformly at each stroke has a freewheel mechanism assigned to the bottom spring plates or the cylinder head and a two-part rotary section. The two parts of the rotary section are connected to one another by way of a ball rotatably arranged in a ball track or shell and influence one another in as much as the turning ring is at any time locked in one direction of rotation by the freewheel mechanism so that it then rotates the upper part of the rotary section assigned to the upper spring plate so that the valve is turned as required. Turning ring and freewheel mechanism are held on the cylinder head by a bearing plate enclosing both of them so that automatic centring is obtained when they are assembled. <IMAGE>
Patent DE-3129890-A1 (DE)
Title: Method for measuring the diameter of linearly moving strand-shaped material
Inventor: KRIEGER JOERG DIPL ING
IPC: G01B11/10
Filed: 1981-07-29
Abstract: Circuit arrangements for measuring the diameter of linearly moving strand-shaped material are known in various forms. They operate either by means of optical scanning with a mirror which is moved mechanically and with the use of light from incandescent lamps or a laser, or by scanning by means of a television camera. All the methods have the disadvantage that they have wearing parts and lead to defective measurements even in the case of slight contamination. The aim of the invention is to avoid these disadvantages. This is achieved by illuminating the measurement material at the rear using infrared light with a wavelength of 900 nm to 1100 nm and using the output signal of an electronic raster in order to determine the diameter of the measurement material and, via a peak value rectifier and a PI controller, to control the infrared radiator.

Patent DE-3135675-A1 (DE)
Title: Internal combustion engine and related assemblies, and auxiliaries therefor
Inventor: EICKMANN KARL
IPC: F02B3/06
Filed: 1981-09-09
Abstract: Superchargers, compressors, expansion systems, pumps, and in particular internal combustion engines are improved by the invention. A solution according to the invention lies in the fact that statically compressing and supercharging assemblies do not allow combustion to occur in the same cylinder space but perform compression, combustion and expansion with the output of work in different chambers, which are interconnected by lines. The combustion chamber is thereby arranged outside the compressor and expansion chambers. A plurality of compressors and expansion systems can thereby function together with a common combustion chamber in which continuous combustion can then also take place. According to one exemplary embodiment feed devices and cleaning arrangements for the combustion of solids, dust or the like such as coal or coal dust or coal sludge are assigned to the combustion chamber. Another solution of the invention is the production of solid carbon fuel blocks and their support and combustion in the combustion chamber of the invention. The aims of the invention are achieved in particular by advantageous design of the individual parts, in which the creation of assemblies with a low clearance volume is achieved, for example, by the shaping of head faces and end faces of the piston, cylinder head and valves. On the basis of a mathematical analysis the engine can be operated for a working cycle under economic medium pressure to high pressure. New axial piston and radial piston designs of compressor and expansion system contribute to the especial compactness of the engine. By means of parts according to the invention, conventional engines can be converted to the new system, in particular by replacing the cylinder covers. The pistons and crankshafts of conventional engines, however, can be retained in these. The advantage lies in the fact that a continuous combustion unit such as a gas turbine is created, which however functions more with static pressures than with purely dynamic pressures and can therefore be used for speed ranges, of which gas turbines are incapable.

Patent DE-3205819-A1 (DE)
Title: Method of producing a high-capacitance busbar having layer-type construction
Inventor: MOSS LEE C
IPC: H01P3/08
Filed: 1982-02-18
Abstract: The capacitance of a laminated busbar or a busbar having layer-type construction is substantially increased by separating each conductor pair by means of a thin, flexible dielectric insulation layer which, in a cutout portion, comprises a thin disc-type ceramic capacitor which may be composed of a barium titanate composition which forms a thin substrate. The opposite sides of the substrate are metallised or coated with a thin metal layer. After introducing the insertion piece into the cutout portion, the insulation strip is partially cured, as a result of which some of the synthetic resin coating on the insulation flows into contact with the insertion piece and fixes it in the cutout portion of the insulation. As a result, the partly cured insulation can be manipulated during its introduction into a busbar assembly, in which it is placed between two strip conductors. The assembly is then laminated in a dielectric sheath in such a way that opposite sides of each dielectric ceramic insertion piece are in contact with the opposite surfaces of adjacent strip conductors. Each insulation layer, which separates adjacent strip conductors from one another in each case, may have any desired number of insertion pieces; for example, strip conductors which alternate in succession can be connected together by means of their projecting connections so that the capacitance between different strip conductors in a busbar can be selectively increased.
