Patent DE-3714028-A1 (DE)
Title: Method for determining correction values for the measured values detected by a displacement-measuring device of a numerically controlled manipulating or production machine
Inventor: DIETZ FERDINAND
IPC: B25J9/18
Filed: 1987-04-27
Abstract: The displacement-measuring devices (L, AK) of the movable axes of machine tools (WM) and robots are measured in a calibration phase with the aid of a precision measuring device (m, R). For this purpose, the parameterised displacement/time curve is prescribed for the approach to prescribed measurement positions (x1, x2, x3) within the possible travel path. When the displacement-measuring device (L, AK) of the machine tool (WM) or of the robot determines that a measurement position (x1, x2, x3) has been reached, a precision measuring device (M, R) measures the actual position. The difference between the results of the displacement measurements of the two displacement measuring devices leads to correction values which correct the measurement results of the displacement measuring device (L, AK) of the machine tool (WM) after termination of the calibration phase. <IMAGE>

Title: Device for avoiding flattening of tyres which are filled with an air or gas mixture and are mounted on vehicles which are left standing
Inventor: KUNDE DETLEF
IPC: B60T3/00
Filed: 1987-08-25
Abstract: Use of the invention prevents eccentricity of a tyre brought about by not using a vehicle over a relatively long period. The invention increases the contact area of the tyre several times over and its circular cutout shape prevents loss of shape (flattening owing to a vehicle being left standing) on the part of a tyre mounted on the vehicle. The invention is made of different materials depending on the model (possible use), so that it is guaranteed that the invention will not lose its shape owing to the weight on the tyre, plus a generous safety margin.

Title: Process and apparatus for replacing the pressurised liquid medium in a hydraulic press, in particular a capsule press, by a curing material
Inventor: POIER PETER
IPC: E04G23/06
Filed: 1987-10-27
Abstract: In a process and an apparatus for replacing the pressurised liquid medium in a capsule press by a curable material, the apparatus comprises a hydraulic cylinder (6), which is subdivided into two cylinder spaces (6', 6''). The pistons (7, 8) of each cylinder space are connected by a piston rod (9). Each cylinder space is subdivided as a result into a right-hand chamber (13, 14) and a left-hand chamber (11, 12). Mortar is introduced into the left-hand chamber of the first cylinder space (6'), whereas the right-hand chamber (13) is filled with the same liquid medium as that present in the capsule press (1). The right-hand chamber (14) of the second cylinder space (6'') is filled with a hydraulic fluid. An increasing of the pressure in the first cylinder space (6') up to the pressure in the capsule press (1) is performed by means of a first pump (26). A displacement of the pistons (7, 8) is performed by means of a second pump (30), so that the mortar is forced into the capsule press (1) and the liquid medium is discharged. <IMAGE>

Patent DE-3901652-A1 (DE)
Inventor: SMITH III ROBERT E
IPC: F16L29/04
Filed: 1989-01-20
Abstract: A pressure-balanced hydraulic coupling for use in undersea drilling and production operations, the coupling having radial passageways communicating between the male and female members such that substantial fluid pressure is not exerted against the face of either member during coupling or uncoupling or during the coupled state. Check valves in both the male and female members are opened when the male member probe is fully inserted into the receiving chamber of the female member. Mutually opposed valve stems extending from each check valve contact one another to effectuate the simultaneous opening of each check valve, and allow fluid to flow through a valve port and then radially through matching fluid passageways in the male and female members. The radial passageways of the male and female members match up at their longitudinal surfaces so that fluid pressure between the male and female members is in a substantially radial direction and is not exerted at the face of either member. Metal seals may be used to seal the annulus formed between the male and female members when they are coupled. The metal seals may be pressure-energized in response to fluid pressure in the coupling to enhance the sealing effect. In an alternative embodiment the seals may be either elastomeric or metal (Fig 2). <IMAGE>

Patent DE-3904831-A1 (DE)
Title: A universal homophonic coding method
Inventor: GUENTHER CHRISTOPH-GEORG DIPL
IPC: H04L9/00
Filed: 1989-02-17
Abstract: Most languages exhibit characteristic statistics. This has grave consequences for encryption since this characteristic can be used for breaking the code. The invention describes a systematic coding which maps symbols from the text alphabet A in symbols from the picture alphabet B in such a manner that the B-weighted pictures, up to a predeterminable degree of accuracy, become a sequence of statistically independent equally distributed random variables. The coding begins with an initialisation phase during which a sequence of coding tables is constructed on the basis of the relevant frequencies of symbol tuples. These tables are then used in the subsequent coding phase for coding the individual symbols from A by using random decisions. The decoding always remains unambiguous. In comparison with the Huffman data compression, this coding is distinguished by requiring much less (logarithmic) storage space whilst retaining the same accuracy.

Patent DE-3912676-A1 (DE)
Inventor: NOE OSKAR DIPL ING
IPC: B21D1/05
Filed: 1989-04-18
Abstract: The invention relates to a method for the continuous stretching of metal strips, according to which the respective strip runs through a set of braking rollers and a set of tension rollers and, in the course of its stretching in the plastic range, is subjected between the two sets of rollers to a stretching tension which corresponds to the yield strength of the strip material. In a pair of tension-stretching rollers inserted between the set of braking rollers and the set of tension rollers, the strip is subjected only to the stretching tension required for stretching it in the plastic range. The transverse strain in the course of the plastic stretching is thereby minimised, with the result that central troughs or, in the case of longitudinal strip division, lateral edges of unequal length no longer occur.
