IPC: F16K17/02
Filed: 1983-01-07
Abstract: In a valve for a compressed fluid line, having a valve housing (10) which contains a shut-off device between an inlet opening (15) and an outlet opening (16) and a second outlet opening (28), which line can be closed by a valve cone (24) connected to a valve stem (23) on which a compression spring acts, the compression spring (32) surrounding the valve stem (23) being supported on the outside of the valve housing (10) and on a flanged nut (55) which is screwed onto the valve stem (23) and is provided with a cap (57), a stop bush (60) is screwed into a central threaded hole (63) in the flanged nut (55), which stop bush (60) has a circumferential groove (61) which originates from its external circumference and has a rubber-elastic ring (62) inserted therein. In this way, a specific maximum pretensioning of the compression spring (32) can be set by screwing the flanged nut (55) onto the valve stem (23) into the position corresponding to the pretensioning, and can be fixed by subsequently screwing the stop bush (60) with the ring (62) into the threaded hole (59) of the flanged nut (55). Because of the self-locking effect of the ring (62), it is not possible to screw the stop bush (60) back out of the threaded hole (59), so that, if the flanged nut (55) is screwed off the valve stem (23) and is screwed on again, only the specific pretensioning of the compression spring (32) is achieved which, in the event of resting on the ...

Patent DE-3307337-A1 (DE)
Title: Antilock system for hydrostatic dual circuit brake systems
Inventor: LUEPERTZ HANS-HENNING PROF DR
IPC: B60T8/34
Filed: 1983-03-02
Abstract: A simplified antilock system for dual circuit brake systems especially in the case of diagonal splitting, with actuation by a conventional tandem master cylinder without hydraulic pump etc. is made possible in that only one of the circuits is ABS controlled, whilst the other is acted upon by the uncontrolled pressure of the master cylinder. A special pressure control device ensures that after shutting off brake fluid can flow out of the ABS brake circuit into the brake fluid reservoir of the master cylinder or into a low pressure hydraulic accumulator, electronically controlled on the basis of signals of a locking sensor on the front wheel of the ABS circuit. Limited feeding of brake fluid into the ABS circuit is possible. Should the non-ABS circuit fail, the ABS control in the ABS circuit is rendered inoperative by hydraulic controls.
Patent DE-3308814-A1 (DE)
Inventor: SCHMITT WALTER ING GRAD
IPC: H03M1/22
Filed: 1983-03-12
Abstract: A measuring system is described which includes a scale which defines a measuring graduation and an array of reference marks. The reference marks are positioned at predetermined absolute positions with respect to the graduation and are used to generate reproduceable electric reference control pulses. In order to identify each of the reference marks a serially allocated code mark is provided which is made up of at least one nonzero code mark segment. Each nonzero code mark segment agrees in spatial pattern with the nonzero associated reference mark in the measuring direction. In order to distinguish nonzero code mark segments from reference marks, the width of the nonzero code mark segments perpendicular to the measuring direction is made less than the width of the reference marks.
Patent DE-3308963-A1 (DE)
Title: Process for the continuous degassing and gas treatment of municipal and industrial waste waters, and flowing and stagnant waters and suspensions
Inventor: SCHINDELE OTTO
IPC: B01F3/04
Filed: 1983-03-14
Abstract: The degassing and gas treatment of the liquid is carried out in two vessels. The liquid to be degassed is introduced into the degassing vessel at the pressure connection branch, and passes through the piping to the rotating atomising disc of the atomiser unit. As a result of the rotation of the atomising disc, the liquid is divided into droplets in a surface-covering and space-filling manner. As a result, a large gas exchange surface is achieved. The degassing is supported by a vacuum applied in the degassing vessel. The exhaust gases are conducted away via a stack. The degassed liquid is pumped to the atomiser unit in the gas treatment vessel and finely atomised. The uptake of fresh gas is supported by fresh gas overpressure and by circulation of fresh gas via gas bubbling systems installed beneath the surface of the liquid.   Note: as a result of the treatment of the liquid according to the above process, an optimal improvement in quality with the highest possible economic efficiency is achieved. The finer the liquid atomisation, the greater the degree of efficiency. The process can be controlled and regulated and can be completely automated.

Patent DE-3340427-A1 (DE)
Title: Laser safety device
Inventor: KELLER GUSTL DIPL PHYS
IPC: H01S3/13
Filed: 1983-11-09
Abstract: In laser transmitters having an interface (optical output socket) which emits a light there is a risk of injury especially to the eyes when no transmission medium (light waveguide) is connected to the interface when the laser is running. A safety device cuts off the laser or reduces the laser output power when it does not confirm the reflective radiation originating in the connected transmission medium for correct termination at a specific point. For this purpose, the laser is modulated with a monitoring signal (pulse or binary correlation signal), and the reflected signal is sampled or correlated in an evaluation device with the monitoring signal which is delayed corresponding to the desired distance to the specific point.

Patent DE-3400987-A1 (DE)
Title: Self-supporting advancing equipment with compression-proof base plate
IPC: E01D21/00
Filed: 1984-01-13
Abstract: The invention relates to self-supporting advancing equipment with a compression-proof base plate for local production of single-span girders or continuous girders lying one behind another, in particular of reinforced or prestressed concrete bridges. After production of a construction section, the complete equipment is advanced by the length of a section to be used again. To move forward, known equipment has to fold down parts of the shuttering in order to produce a free passage for the columns standing in the way. High costs arise from the mechanical outlay and the work-intensive operation. In order to simplify the equipment, a compression-proof base plate is arranged, which is connected rigidly to all other parts of the equipment. On advancing, the base plate slides between the construction section just erected and the column, the load of the girder being introduced via a sliding bearing into the pressure plate and from there via a second sliding bearing directly into the column. The load of the equipment is likewise introduced directly into the column via the lower correspondingly enlarged sliding bearing. The arrangement of the equipment, of the construction section and of the column is shown in cross-section in Fig. 6. <IMAGE>

Title: Method for measuring luminance and device for carrying it out
Inventor: MUIGG PETER ING
IPC: G01J1/04
Filed: 1984-02-14
Abstract: When controlling the illumination of selected zones in interiors, for example of workplaces, use is made of the luminance of the regions of the sky and other surfaces of the external environment that are relevant for the lighting ratios. In this case, the external environment is subdivided into solid-angle regions, and the luminance of each component surface is individually measured. The measurement results separately transmitted to an evaluation unit are processed there and correction measures are taken in the event of deviation from the desired illumination situation. A measurement device suitable for this purpose has, for example, a measurement head (1) which is to be set up in the open and in which measurement cells (2) which are approximately hemispherical, are arranged radially in relation to the centre point, each measurement cell (2) embracing one solid-angle region. <IMAGE>

Patent DE-3423285-A1 (DE)
Title: Process and apparatus for removing nitrogen oxides from exhaust gases
Inventor: FUCHS UWE
IPC: B01D53/84
Filed: 1984-06-23
Abstract: The invention relates to a process and an apparatus for the biological purification of nitrogen oxide-containing exhaust gases. The nitrogen oxides are reduced to harmless nitrogen under anoxic conditions, in the presence of a substrate containing oxidisable organic carbon compounds, by microorganisms immobilised in the reactor on special support elements. Municipal or industrial waste waters are particularly advantageous as reduction substrates, since, in addition to the exhaust gas purification, waste water purification is also performed at the same time. Ultimately, two environmentally harmful products are neutralised with the aid of microorganisms. In contrast to some chemical processes, no new environmental toxins are therefore produced which would then in turn have to be disposed of.

Patent DE-3427702-A1 (DE)
Inventor: HIRT EDMUND
IPC: B65D77/20
Filed: 1984-07-27
Abstract: The package consists of a strip of plastics foil or sheeting and a strip of paper, whereby the two strips are sealed together at their margins, so as to permit opening by a peeling action. The seal consists of two groups of sealing elements. The sealing elements of group 1 are of small dimensions and ensure "sealability", while the sealing elements of group 2 are linear having a restricted width and which are arranged such that they run transversely to the direction of peel. The arrangement combines a high degree of mechanical strength with ease of peeling during which the tearing-out of fibres from the packaging is minimized.
Patent DE-3431652-A1 (DE)
Title: Hydraulic tool clamp
Inventor: SCHOEN HANS
IPC: B30B15/02
Filed: 1984-08-29
Abstract: This tool clamp can be designed as a push-in clamp in the conventional manner or as a fitted clamp for integrated fitting in particular in a press ram. As a push-in clamp, it essentially contains a housing block (12) which starts from a T-shaped foot (10) and accommodates the functional parts. These functional parts include a piston/cylinder arrangement which runs with its cylinder axis transversely to the tool bearing surface at the press bed or ram. In this arrangement the cylinder (14) is preferably movable on a fixed piston rod (13). At its free end it merges into an axial extension (24) in which the actual clamping piston (26) is guided in a transverse bore. After the extended position of the cylinder (14) is reached, the clamping piston (26) is automatically acted upon by the pressure medium from the piston/cylinder arrangement and is thus used for clamping the tool. The use of a clamping piston (26) which can be returned into a neutral position instead of a fixed clamping piston provides, among other things, the advantage that the tool clamp completely frees the tool in the release position. Unlike known tool clamps which enclose the clamping strip of the tool in a claw-like manner, the novel tool clamp permits a problem-free tool change without having to remove the tool clamp itself from the press bed or ram. <IMAGE>
