Patent DE-19545693-A1 (DE)
Title: Efficiency verifying method for catalyst in IC engine
Inventor: STAUFENBERG ULRICH
IPC: F01N11/00
Filed: 1995-12-07
Abstract: The method involves forming the ratio of the output signals from lambda probes (5,6) arranged before and after the catalyser (2) and comparing the ratio with a threshold value. If the threshold is exceeded the catalyser is categorised as faulty. An extreme value for the probe output signal is determined for each probe after the probe has been changed. Extreme values are obtained from continuous difference formation of successively sampled output signals of each lambda probe, whereby after a sign change the differences from positive to negative and from negative to positive are detected respectively as a maximum and a minimum.

Title: Cycled transporting of moulds holding refrigerator or freezer cabinets during insulation foaming
Inventor: GIESLER KARL DR
IPC: B29C33/36
Filed: 1996-01-12
Abstract: In a process for moving moulds in cycles on a horizontal conveying system the moulds (3) pass along a mould servicing zone (1) with stations (1.1-1.5) for different operations and through a temperature-controlled polymer curing section (2) before returning to the servicing section (1). Open tools (3.1) move through the servicing section (1) at a high speed and with a large spacing between them, of preferably 1.1-3 times mould width. At the end of the servicing zone (1) the closed moulds (3), including cabinets, transfer to the curing zone (2) and both their speed and spacing, are reduced, the spacing being 1.0-1.1 times the mould width. Moulds (3.2) continue through the curing zone (2) at this lower speed and gaps (12) between moulds can be opened or closed as required. Mould speed and spacing increases again just prior to reentering the mould servicing zone (1). During long breaks in operation the moulds (3) are moved from the servicing zone (1) into the gaps(12) between moulds (3) in the curing section (2)  to maintain their temperature. Process plant includes two long parallel transporting sections (9) each connected at both ends by a lateral transporting section(10). The long sections (9) are divided into several separately-driven sections, the drive (4) for the sections in the mould servicing zone (1) running at a higher speed than the drives (4) for each section of the curing zone (2) and the transition sections at the start of and end of the curing zone (2) have variable speeds. Sensors (14) for halting mould movement in the servicing zone (1) have the larger spacing of moulds in this zone and similarly sensor spacing in the curing zone (2) corresponds to the smaller mould spacing. In the latter the sensors (14) are switched on and off to open or close gaps (12) between moulds (3).

Title: Table preferably used as playing table
Inventor: THON SIEGFRIED
IPC: A47B25/00
Filed: 1996-02-15
Abstract: There is a mechanical coupling of a table plate (2,2') with a case (3,3'). Through the movement of the case plate relative to the underframe, a lifting and/or lowering of the case's means of mechanical movement transformation follows. In an elevated position, the access opening of the case is covered through the table plate. The table plate may be rotatably mounted about a vertical axis. The case may be designed case-shaped such that the access opening can be provided in the region of the upper cover surface. The movement transformer elements (7,8) may have means of converting a rotation motion of the table plate to a vertical lifting motion of the case.
Patent DE-19613175-A1 (DE)
Title: Complex measuring method of thread characteristics at external and internal threads
Inventor: BECK CHRISTIAN DR ING
IPC: G01B5/20
Filed: 1996-04-02
Abstract: The measuring method is carried out and the thread profile is determined at one side in a scanning process. A symmetry line (S) of the external or the internal thread of the test specimen (1) is formed. This additionally about the distance (A*) characterises the respective type of thread, which corresponds to the half desired flank diameter (d 2soll), is shifted in the axis section in the thread contour (1.G) of the test specimen. At least one measurement of the actual thread gauge (B ist) is measured, between the intersection points (Z) of the symmetry line (S) with the thread contour (1.G). In addition the actual pitch (P 1st), also the flank angle (alpha ist) or the actual part flank angle (alpha ist/2) are determined. Emanating from this, the half actual triangle height (H ist/2), determines the position of the actual flank diameter (d 2ist), the flank diameter deviation (A d2 = d 2ist - d 2soll) from the measurement values (B ist), (P ist) and (alpha ist) or (alpha ist/2), according to the formula:

Title: Adjuster for internal combustion engine gas valves
Inventor: SCHEIDT MARTIN DR ING
IPC: F01L1/344
Filed: 1996-04-17
Abstract: The adjuster comprises a pressure medium, to place the adjuster piston (6) in its starting position, which enters along annular channels (25,27) acting as distribution spaces joined up via offset transition bores (28,29). The two pressure spaces (13,14) defined by the piston should be sealed from one another. The two channels lie in two sleeve elements of the valve adjuster (1), notably a seal support and a guide bushing (26). The transition bores should be offset 120 deg, one bore permanently lined up with a vertical axis of the adjuster (1) on assembly. The sealing ring (39) between the pressure spaces (13,14) is positioned on the bushing (26) so the sealing lip bears on the inside of the switching sleeve (7) concentric to the bushing. The two rotation-symmetrical seal support and bushing should both be exactly positioned. The angle of the bushing to the seal specified can be obtained by means of a twist preventer composed of a toothed ring boss to fit into a bore provided in the seal support.

Title: Tractor hitch for ploughing
Inventor: HESSE HORST DR
IPC: A01B63/112
Filed: 1996-09-26
Abstract: The plough (12) is supported on the three point hitch, with the traction force split between the two lower points of the hitch. Sensors (15,16) on the lower hitch points measure the separate traction forces and enable the driver to balance the forces by adjusting the angle of the plough frame. This is achieved by a servo motor (19), or a hydraulic ram, between the hitch frame and the plough frame. The adjustment can be manual, using two indicators on the driving position, or automatic using an automatic control (29). The reference value for the two traction forces is computed from the mean value of the two forces and is used to correct the balance.

Title: Real=time fluid flow measurement method using non=orthogonal heating wire and hot film probes
Inventor: LAGIES ARRASCH UWE
IPC: G01P13/02
Filed: 1997-02-06
Abstract: The involves using hot wire and hot film anemometry. The standard values of the probe are reversed before the measurement and are sorted so that the memory addresses can be calculated with the measurement. The use of non-orthogonal hot wire arrangements is possible, which have a large measurement range that need not be accurately constructed, and which are smaller and thus allow point type measurements. The probes must be recalibrated after a basic calibration only when needed at fewer calibration points. The probe calibration is divided into a basic calibration and a subsequent calibration. The basic calibration must be always carried out but the later calibrations are reduced to fewer points. The later calibrated points are then used to correct all values of the basic calibration.
