Title: Hydropneumatic suspension system for goods vehicle - uses spring reservoirs with non-overlapping pressure regions
Inventor: RUNKEL WALTER DIPL ING DR
IPC: B60G17/015
Filed: 1992-07-18
Abstract: The hydropneumatic spring system has a hydraulic spring strut (2) which acts against two hydropneumatic spring reservoirs (20, 22) hydraulically arranged in parallel. The reservoirs are effective in different pressure regions. The reservoirs are so dimensioned that their different pressure regions are spaced from each other without any overlapping. Each of the reservoirs is formed as a pressure converter in which the pneumatic pressure is less than the associated hydraulic pressure.

Title: Delivery unit for supply fuel from tank to IC engine of motor vehicle - has delivery set which includes internal gear pump driven by electric motor with its set of gears rotating in gear chamber formed by ring type plates.
Inventor: KRAUTER LOTHAR DIPL ING
IPC: F04C2/10
Filed: 1992-08-18
Abstract: The pump chamber(45)is formed by a ring type intermediate plate(36) and two cover plates, which are fitted respectively at the endfaces of the intermediate plate(36).

Inventor: HEIDT HEINRICH
IPC: F16D48/06
Filed: 1992-08-20
Abstract: The circuit monitors an electromagnetically operated clutch, in which the electromagnet winding is connected to a switchable voltage source (2). A measuring resistor (8), across which a voltage sensor is connected, is arranged in series with the winding of the electromagnet. The voltage source is a DC voltage source on which a cyclic AC voltage (U(AC)) is superimposed whose DC voltage component (U(DC)) has two defined levels as a function of an engaging and disengaging signal.The winding is connected to the voltage source in the engaged and disengaged state of the clutch. The voltage sensor is connected to an evaluation circuit (10) for the AC voltage applied to the measuring resistor.

Inventor: STIEL JUERGEN
IPC: B41F27/12
Filed: 1992-09-18
Abstract: In a device for supplying printing plates (27, 67) to a plate cylinder (2) and for carrying away the printing plates (27, 67) from the printing cylinder (2), the problem consists of exchanging plates in the narrowest space without causing components of the device to prevent access to the printing rollers or make it more difficult. For this purpose, chutes (9, 11) with plate exchange guiding elements (43, 44) can be swivelled in a rest position.
Patent DE-4234523-A1 (DE)
Inventor: HOELZL STEFAN
IPC: B61F5/24
Filed: 1992-10-13
Abstract: A process for controlling the wagon body of a vehicle may be used by itself or in combination with steel springs. This control of the height of the wagon body is characterised in that it has relatively small geometrical dimensions and a relatively low energy consumption. For that purpose, a further pressure accumulator (9) is connected in parallel to the hydraulic medium feed pump (8), and both work together against the pressure of the hydropneumatic spring accumulator (11). The pressure accumulator (9) may thus be loaded while the vehicle is travelling, so that the pump used need not be designed to withstand a rapid load change after a peak load.

Title: Automatic load coupling unit for crane - consists of crane tackle upper part with pivoted hook segments which enter bore of load mounted lower part and swing out to hook behind shoulder of bore
Inventor: LANDGRAF KARL
IPC: B66C1/66
Filed: 1992-11-28
Abstract: Forming part of the crane tackle is an upper part (1) with a ring of four hook segments (12) pivoted at the bottom on a radiused shoulder. A sliding retaining ring (15) normally holds the hook segments inwards. Attached to the load is a lower part (2) with a stepped bore (3) into which the upper part can be lowered. When the upper part enters the bore of the lower part the retaining ring (15) is left behind and the hook segments are able to swing outwards against the wall of the larger bore section (5). The load can now be raised because the hook segments seat behind the radiused shoulder (6). ADVANTAGE - Load can be handled solely by crane driver. Simple and convenient in use. Especially applicable in hazardous environments.

Patent DE-4308104-A1 (DE)
Title: Thread-cutting device
Inventor: SPITZER DANIEL
IPC: B23G1/26
Filed: 1993-03-15
Abstract: The invention belongs to the technical field of metalworking. The problem to be solved by the invention is that of abandoning the hitherto unsatisfactory guide characteristics on tools of such a type, in particular due to the actions of moments, and achieving a lubricant repository effect as well as nonetheless relatively high simplicity of the tool. The thread-cutting die (2) is interchangeably inserted into a one-piece die holder (1) made of steel and is retained by locking screws (5). The die holder (1) has a guide bore (4) having the dimensions 1.002 . z < x < 1.03 . z and 0.6 . z < y < 1.5 . z. The advantageous effects consist in particular in the fact that tilting moments are avoided, that the lubricant is held by the capillary action in the guide, and that work can be carried out over hollow spaces into which no chips are allowed to fall.

Patent DE-4332513-A1 (DE)
Title: Control valve for exhaust gas recirculation
Inventor: DISMON HEINRICH
IPC: F02M26/70
Filed: 1993-09-24
Abstract: Such a control valve is known in internal combustion engines but must have a constantly varying flow in order to rapidly attain a predetermined rate of exhaust gas recirculation. In order, for example in a diesel engine, to prevent smoking and load drops of the internal combustion engine, a more rapid switching of the valve is also necessary. For this purpose the new control valve has the characteristic feature that the valve part is formed from a flat slide and a flat seat interacting therewith, which each have a number of openings, the flat slide being part of a periodically oscillating, electro-magnetically excitable mass spring system with adjustable, variable amplitude. The new control valve permits rapid adjustment and switching.

Title: Method for selective obtaining of suitable quantities for continuous spatially resolved testing of the material parameters close to the surface for manufacturing control, and arrangement for carrying out the method
Inventor: KOESTERS HEINER DIPL CHEM
IPC: G01N27/90
Filed: 1993-09-30
Abstract: The invention relates to a method for selective obtaining of suitable quantities for continuous spatially resolved testing of the material parameters close to the surface for manufacturing control, and an arrangement for carrying out the method. This method combines the suitable micromagnetic quantities, such as induction, Barkhausen noise and eddy-current losses. This large number of parameters is evaluated after corresponding preprocessing by means of fuzzy logic, which is carried out according to the invention in such a way that the method can be matched simply to the corresponding technical testing problem by the user, without detrimental effect on the reliability of the method. The use of fuzzy logic furthermore makes it possible to distinguish between the individual material properties, even though there is not a complete mathematical model for describing the system. The arrangement for carrying out the method is essentially characterised by two magnetisation coils in a Helmholtz-like arrangement, which is combined with a movable sensor coil, arranged at right angles thereto, for scanning the surface. This sensor coil is guided at a defined separation from the sample surface, and the corresponding signals are fed to the fuzzifier via suitable filters and preamplifiers.

Title: Laser cutting head - with secondary annular nozzles surrounding the main booster gas nozzle.
Inventor: KAGA KUNIHIKO
IPC: B23K26/14
Filed: 1993-10-21
Abstract: The laser processing head incorporates a main booster gas nozzle (1) in the middle region of the head, and at least one annular secondary booster gas nozzle (2) surrounding the main nozzle (1). To increase the effect of pressure and flow variation of the main gas jet, the diameter of a jet exit (2a) of the secondary nozzle (2) is not made less than the diameter of the jet exit (1a) of the main nozzle (1). There are 20 variants of the cutting head, each with its preferred features. For example, the main nozzle (1) is provided with curved vanes running along its inner wall to produce circulatory gas flow. Alternatively, the nozzle inner wall is provided with twisting grooves. As a further alternative, there is a number of auxiliary jets entering into the main jet at a certain angle, etc. The gas flow rate and pressure are program-controlled. USE/ADVANTAGE - In laser cutting installations. The quality of the cut surface is improved and the rate of cut is increased as a consequence of optimisation of the booster gas supply.
