Title: Disc brake for vehicles
Inventor: BIEKER DIETER
IPC: F16D65/14
Filed: 1986-03-27
Abstract: The disc brake, suitable in particular for road vehicles, has a calliper 2, which has centrally, seen in the circumferential direction, a diaphragm actuator 15 with an axial direction approximately parallel to the radial plane of the brake disc. When acted upon by a pressure medium, the diaphragm actuator 15 acts on a rotary lever 4 to rotate an eccentric shaft 6, which is mounted rotatably in the calliper, parallel to the radial plane, and ends at both ends with eccentrics 7, which are able to press against spindle devices. The rotatable parts of the spindle devices are coupled to one another by means of driving pulleys 32 and a V-belt 35, so that only synchronous readjusting operations are possible. The drive for the readjusting device can be accomplished from the rotary lever 4 via a deflecting roller 36 for the toothed belt 35. A compact construction of the disc brake is obtained, pneumatic actuation of the diaphragm actuator 15 sufficing for adequate, uniform application of the disc brake. <IMAGE>

Title: Method of plugging (sealing) leaks in a system traversed by a liquid medium
Inventor: WARTUSCH JOHANN
IPC: F16L55/164
Filed: 1987-03-12
Abstract: Method of plugging leaks in a system through which a liquid medium flows. Examples of such systems are hydraulic regulation and control apparatus and cooling apparatus in which the medium flows under pressure. Pores in the lines and in the units themselves lead to a loss of liquid which may ultimately result in failure of the apparatus concerned or which renders expensive repair work necessary. To overcome these disadvantages the liquid medium contains an additive which forms, in a chemical conversion with water, a compound which is insoluble in the coolant and which deposits at the leakage site, thereby plugging it. Suitable additives are in particular silanes, but also titanates and esters of boric acid. To accelerate the reaction it is also possible to add a catalyst.
Patent DE-3709395-A1 (DE)
Title: Method and device for digitally determining a number proportional to rotational speed of a body
Inventor: REINERS DIETER DIPL ING
IPC: G01P3/489
Filed: 1987-03-21
Abstract: The subject matter of the invention is a method and a device for determining a number which is proportional to the rotational speed of a body by means of an angle sensor which generates digital signals during their rotation. The time is measured by counting the periods of a reference oscillation in cyclic sequence up to a prescribed maximum value. An angular position value is continuously updated in the case of changes in angular position of the body and stored, and the time value present up to the instant of the change is stored. The stored angular position value and the stored time value are read out at time intervals given by a constant interrupt interval. In each case, the angular position value read out in the preceding interrupt interval and the time value read out are subtracted from the read-out angular position value and the time value. The difference between the angular position values is divided by the difference of the time values and multiplied by a constant. <IMAGE>

Title: Device for testing electroplating baths
Inventor: CATALDI ANTONIO
IPC: H05K1/02
Filed: 1987-06-15
Abstract: A device is described for testing electroplating baths (electrolytes) which serve for metallising printed-circuit boards for electronic appliances. Increasingly, printed-circuit boards are used having holes which are plated through by electroplating. The test methods known hitherto for assessing an electroplating bath do not permit adequate quality assessments for printed-circuit boards of this type. Only improvements of known test devices make it possible, using a test cell having an angular shape, and by means of a suitable arrangement of two anodes, to assess unambiguously the bath quality (electrolyte) even when taking into account the metallised holes in a printed-circuit board.

Title: Boot, in particular ski boot
Inventor: GAUSRAB KLAUS
IPC: A43B5/04
Filed: 1987-08-13
Abstract: A spring arrangement (1) for shell parts (7, 13) of a shoe, which are movable in an articulated manner in relation to one another in the forward lean direction, has, completely surrounded in a housing (20), two groups of compression springs made of a closed-cell polyurethane elastomer (PUR) which have a very progressive spring characteristic line by virtue of the fact that only one group of springs is effective on a first part path and a second group can be connected on a second part path. The path-dependent response of both groups of springs can be adjusted separately and moreover all springs are designed as damped springs as a result of their material properties. As a result, an adjustable forward-lean springing, the hardness of which can be varied in a path-dependent manner, is possible for the boot shaft (5). <IMAGE>

Title: Control system on rolling mills
Inventor: STRACH LOTHAR
IPC: B21B33/00
Filed: 1987-11-02
Abstract: Rolling mills and calenders are operated by means of hydraulic cylinders to produce the rolling force. In the case of four-high sheet rolling mills, the rolling forces can be up to 8,000 t. Since the roll gap must always be controlled and adjusted under maximum rolling force, there is always the disadvantagage with hydraulic technology that the hydraulic system hinders itself in the achievement of fine adjustment due to the fact that maximum working pressure occurs simultaneously with maximum piston-sealing friction due to the working pressure. The use of a mechanical roll-gap adjustment system at maximum rolling force by means of toggle levers and ball screws and elements provided with rolling support considerably reduces the control forces required, allows finer adjustment and permits adjustments in the  mu m range.

Title: Axle suspension for motor vehicles, especially rear-axle suspension
Inventor: BUFLER ERNST DIPL ING
IPC: B60G11/40
Filed: 1987-12-17
Abstract: The invention relates to a rear-axle suspension for motor vehicles having flexurally and torsionally rigid longitudinal links which at one end carry wheel pivots and at the other end are articulated on the vehicle body pivotably about an axis extending transverse to the longitudinal direction of the vehicle and in a vertical plane, whilst the said longitudinal links, in the region of their body-side ends, either are connected to one another in the manner of a composite-link axle by means of a torsionally resilient transverse strut or each is independently prevented from tilting about its longitudinal axis by means of an additional axle link extending approximately transversely relative to the longitudinal direction of the vehicle. The vehicle springing takes place by means of a transverse leaf-spring arrangement which is rigidly fastened to the vehicle body in the middle of the vehicle and the free ends of which are articulated on the longitudinal links in the region of the wheel pivots, with especially designed rubber/metal bearings being interposed. In order to achieve a constraint-free constant-track straight guidance of the longitudinal links, the elastomeric elastomer elements of the rubber/metal bearings aligned with the bearing axis in the longitudinal direction of the vehicle are designed and connected to the outer and inner sleeves of the rubber/metal bearings in such a way that the outer sleeves are transversely displaceable relative to the inner sleeves during the compression and expansion of the springing of the vehicle wheels. <IMAGE>

Filed: 1987-09-24
Abstract: In order to improve a discharge channel for transverse-flow high-power lasers having a dielectric channel wall and having at least two mutually opposite electrode arrangements, between which a discharge space (through which a laser gas flow passes) is located and of which at least one has a metal core (which is held on the inside of the channel wall) and a dielectric covering body (which engages over said metal core and screens it from the discharge space) in such a manner that the discharge between the electrode arrangements is as uniform as possible, it is proposed that the metal core and the covering body be constructed such that a field strength is produced between the electrode arrangements which reduces in the laser gas flow downstream direction and leads to a constant discharge current density along the laser gas flow.
Patent DE-3805092-A1 (DE)
Inventor: WEID HELMUT
IPC: A01D34/73
Filed: 1988-02-18
Abstract: In a two-armed cutter bar (10) for a lawnmower with a vertically rotating shaft, the cutters (14) are fastened at each of the two ends by means of a respective single fastening bolt (36). The end portions of the cutter bar (10) have conical rotary guides (24), into which fit correspondingly conical rotary guides (38) of the cutter carrier plates (32). This ensures centering and rotary guidance. A positive junction between a rib (46) of the cutter carrier plate (32) and a bead (20) of the cutter bar (10) makes a positive connection which is broken under excessive stress when a stone or the like is struck, the result of this being that the cutter (14) can rotate. The positive connection can be broken in this way in the elastic or plastic range if the parts engaging in one another are resilient or if, for example when an expansion bolt is used, the length of the bolt is increased when excessive load occurs. <IMAGE>
