Title: Safety lock with cobalt in screw shaft and nut - has push-in peg anchored by bolt in screw shaft and nut and includes barb on peg to stop nut turning and has lock end filling out screw slit
IPC: F16B41/00
Filed: 1991-11-30

Patent DE-4202149-A1 (DE)
Inventor: HORSCH WILFRIED
IPC: B23B41/16
Filed: 1992-01-27
Abstract: The present invention relates to a fine boring tool with a mounting shank (3), which has a flange (5), and a cutting-edge holder (11) for accommodating a cutting edge (13) which is arranged in the end area of the fine boring tool (1) opposite the mounting shank (3).

Title: X=Ray quantum pulse transmission spectrum measuring system - has reduced energy requirement for X=ray quanta
Inventor: HARDING GEOFFREY DR
IPC: G01N23/201
Filed: 1992-02-06
Abstract: A system, for measuring the pulse transmission spectrum of x-ray quanta, has a polychromatic x-ray emitter (20); a primary aperture arrangement (21), between the emitter and the test region, for stopping down a primary beam (28) passing through the test region on the generatrix of a cone; a detector array (D) for detecting x-ray quanta which have been elastically scattered in the test region; and a secondary aperture arrangement (27) which is located between the test region and the detector array (D) and which has slit openings (S1,S2) arcuately enclosing a system axis (24) passing through the emitter. The novelty is that the system design and the slit opening (S1,S2) arrangement are such that the scattered radiation can pass through each opening only from part of the test region to the detector array. Thus, scattered radiation from a test region portion (A-F) nearer the emitter is detected by detector elements (1-6) which are closer to the system axis than is the case for scattered radiation from a test region portion (G-L) further from the emitter. The test region portions, from which scattered radiation is detected through the openings by the detector array, do not overlap. USE/ADVANTAGE - The system is used e.g. for identifying (esp. crystalline) materials in luggage. The secondary aperture arrangement is relatively simple and the requisite x-ray quantum range can be reduced compared with than in EP-462658.

Abstract: The safety circuit, as in P4127421, has an actual and/or required parameter value subjected to a test oscillation with a monitoring comparator used to verify the function of all components of the safety circuit, which operates an automatic shutter upon failure. The self-testing oscillation is provided via the laser beam using a deflection system in the beam path, under control of a piezoelectric sensor element. Thus, in a laser operating tool with a laser scalpel, the laser can be automatically switched off when the scalpel strays from the operating field it has learnt to be safe. USE/ADVANTAGE - Esp. for surgical laser handled by operation robot with self-learning function. Extended range of application, including in aircraft, spacecraft or motorcar industries.

Patent DE-4235217-A1 (DE)
Inventor: ADOLPH ULRICH DR ING
IPC: B64D13/08
Filed: 1992-10-14
Abstract: The invention relates to a combined cooling and heating process for air-conditioning a compartment (8) and also to a device for carrying out the process, in particular for use in passenger train carriages. With this process and device, it is possible to either cool or heat a compartment (8). If the compartment (8) is no longer to be cooled but heated, according to the invention two valves (23, 24) are reversed, and the process air flows through the units required for cooling, heat exchanger (5) and regenerator (6), without heat exchange. The air heated by the compressor (2, 3) passes to the useful-heat exchanger (7) via a bypass pipe (31). The air cooled in the useful-heat exchanger (7) but still under pressure is conveyed via a further bypass pipe (22) to a turbine (4), where it is relieved of pressure and is released to the environment. The air of the compartment (8) to be heated is here sucked in by a pre-compressor. <IMAGE>

Patent DE-4305499-A1 (DE)
Title: Hydraulic hydroelectric power plant
Inventor: WUERTH GUSTAV DR
IPC: F03B17/02
Filed: 1993-02-23
Abstract: At great water depths, physical conditions prevail which differ from those at the surface of the earth. Such physical conditions can be transferred to the surface of the earth; they are known and can be mastered. The utilisation of these differences between water at depth and the surface of the earth open up a wide field and render it possible to obtain a relatively large amount of energy by using a small amount of energy. The present application is intended to develop one possibility for this. Patent Claim 1 is intended more for the purpose of expounding the theory, and Patent Claim 2 for its practice. According to Claim 1, a ball or the like is inserted at the bottom into a water column of, e.g., a water height of 100 m via a sealing device, with a specific weight of just below 1, by a cylinder with a movable piston. In order to compensate the pressure difference in front of and behind the piston, a helical spring preloaded to 10 atmospheric excess pressures (gauge pressure in atmospheres) is attached behind the piston. The cylinder space in front of the piston is filled, in a manner free from bubbles with low-pressure water (overrun water), and when the sealing device is opened the pressure is increased at once to 10 atmospheric excess pressures without the addition of high-pressure water. A water pressure of 10 atmospheric excess pressures thus prevails in front of the piston, and behind the piston the helical spring presses against the piston with the same pressure. There is now therefore a need for only a relatively slight pressure on the helical spring in order to press the ball with the surrounding water into the water column, where it then floats upwards owing to the smaller specific weight ...
