Title: Device for attaching a component to an anchoring point
Inventor: WEMAN PER OLOF
IPC: B60R22/26
Filed: 1982-05-18
Abstract: A device for attaching a belt lock (1) to an anchoring point (8) in a vehicle, a sudden pushing or pulling force on the belt lock (1) being absorbed in a damping fashion. In order to attach the belt lock to the anchoring point, not, however, in the simple rigid manner but rather in such a way that the lock is movable and yet, in the event of a sudden application of force, is held rigidly at the anchoring as if rigidly attached, there is provision according to the invention for a tubular element (9) to be permanently attached to the anchoring point (8), a lock bar (2) which secures the belt lock (1) being arranged in the said tubular element (9) so as to be displaceable counter to a resistance, and for the lock bar (2) also to be attached to a first securing device, for example a screw (4) which can break more easily. <IMAGE>
Patent DE-3221098-A1 (DE)
Title: Fluid-flow machine, in particular as a prime mover
Inventor: SCHATTA MARTIN
IPC: F01D23/00
Filed: 1982-06-04
Abstract: If a slightly concavely curved sheet-metal panel is held as a drag surface, for example having a length of 1,000, width of 200, and thickness of 1 mm, on edge against a flow, the theoretical pressure drag on its front edge is approx. a two hundredth part of the value for the vertical position of the panel. The invention makes use of this physical effect, i.e. a rhythmically oscillating longitudinal movement, to mechanise reciprocal 90 DEG  rotations of the ends of drag surfaces, or to control them via an appropriate automatic drive mechanism so that, inter alia, a torque is produced for generators. The figures represent the fluid-flow machine particularly as a prime mover, which consists in its basic construction of, on the one hand, floating toothed rods or drive cables which always engage with back gears, reversing/speed-change gear mechanisms, a flywheel, and a generator, which are arranged on the fixed floating platform, and their front ends accommodate drag surfaces which can be swivelled by 90 DEG . As a result, it is not a rotationally symmetrical but a longitudinal acquisition of large forces that is converted at low speed into a torque in surf, ocean currents, fjords and rivers.

Title: Clamping bracket
Inventor: MEZ GEORG
IPC: F16L23/14
Filed: 1983-03-19
Abstract: Air conditioning ducts consist of duct elements which are prefabricated at the works and, at their abutting edges, support special frame flanges. The duct elements are arranged in a row at the building site. In this arrangement, in each case two frame flanges are located on one another in mirror-image symmetry. Clamping brackets, which are placed over the frame flanges, are used for rapid assembly. Clamping brackets are mass-produced articles, and their production must be extremely simple and cheap. It must be easy to fit the clamping brackets to the frame flanges. According to Fig. 4, the clamping bracket 11 consists of a bracket 12 and a clamping lever 13. The bracket 12 is formed by two plates, and the clamping lever 13 is also flat like a plate. The clamping lever 13 is supported between the plates on a bearing bolt 27, such that it can pivot. The clamping lever 13 is made up of a lever arm and a stud. Initially, during pivoting in the direction of the arrow 66, the stud presses continuously against the oblique wall 54. In consequence, the frame flanges 44 and 46 are aligned with respect to one another. After this, the stud presses against the compression wall 52. It can be pivoted into a stable beyond top-dead-centre position without any sudden change in force. The frame flanges 44 and 46 are connected rigidly and securely. <IMAGE>

Patent DE-3320591-A1 (DE)
Title: Slide lining for chimney soot doors
Inventor: PFANNKUCHEN ERNST
IPC: F23J13/08
Filed: 1983-06-08
Abstract: In multi-shell chimneys, thermal expansion movements occur between the inner pipe and the chimney casing, imposing special requirements on the lining of the cleaning doors. In contrast to hitherto known products, the slide lining for chimney soot doors fulfils all requirements, since, with a connection piece placed in the inner pipe and with the front plate of the slide lining sliding on a frame in each phase of movement it covers the expansion gaps in the casing brick and seals the inner pipe if the cleaning space cross section is constant. Even horizontal movements and settling phenomena are compensated for by the slide lining. Clamping bars fastened to the frame hold the slide lining, in whose front plate the door shoulder profile is embossed, in the slide plane and in the connection to the chimney. The frame with cleaning connection edges is screwed to the casing brick and fixes the casing brick recess. A cover, which can be flush-fitted by plastering, forms an visual closure, acts as an additional seal and protects from soiling. All the parts can be mounted rapidly and in dry form, without auxiliary materials, and are maintenance-free and can later be interchanged without consequential damage. The slide lining for chimney soot doors is provided as an overall unit in a plurality of sizes to fit existing soot door sizes, preferably for the 13.5 x 30 cm, 20 x 30 cm and 25 x 30 cm doors, or for chimneys with more than six full floors, with correspondingly larger slide surfaces.

Title: Method for the contactless, emissivity-independent radiation measurement of the temperature of an object and device for carrying out the method
Inventor: TANK VOLKER DIPL ING
IPC: G01J5/00
Filed: 1983-06-16
Abstract: A method and a device for the contactless, emissivity-independent radiation measurement of the temperature T of a natural or artificial object is provided, in which the radiation measurement is carried out in two or more limited spectral regions in which the transmittance tau of the atmosphere is at least approximately equal to one. In order to determine the temperature T and/or the emissivity  epsilon of the object, a radiance curve which passes through the measured intensities is calculated for the intensities measured in a single measurement operation in the various spectral regions. For this purpose, iterative calculation is used with the aid of Planck's Radiation Law to calculate this radiance curve in such a way that it is the sum of the radiance of the object (with the temperature TObj and the emissivity  epsilon ) and the radiance of the surroundings (with the temperature TUmg), reflected at the object (with the reflectance of the object).
