Patent DE-3735000-A1 (DE)
Title: Device for testing the tightness of drainage pipes
Inventor: SCHAEFER FRIEDRICH
IPC: G01M3/02
Filed: 1987-10-16
Abstract: Drainage pipes which, in operation, are subjected to a raised dynamic pressure, must undergo tightness testing in sections at the time of installation or during alteration work. It is to be possible to carry out this testing with little outlay and, as far as possible, without additional components. A cover is proposed for this, with which the drain-valve housing or inspection housing, which is present anyway, can be closed. The cover contains two connection holes for delivering pressure medium or deaerating the pipe section and for a pressure indicator. To fix the cover, use is made of fastening elements provided in any case on the drain-valve housing, e.g. setscrews on the clamping flange, or the cleaning aperture in the immersion wall.

Title: Method of constructing a trench wall
IPC: E02D29/02
Filed: 1988-02-19
Abstract: In a trench wall which is only to perform a sealing function in the lower area and is also to perform a load-bearing function in the upper area, the method provides for suitable coarse-grained filling material (7) to be poured into the trench (4), filled over the entire height with sealing suspension (5) during the construction, up to the level of the area (6) in which the trench (4) is only to have a sealing action, and then for the suspension (5) to be displaced by high-quality concrete (9) in the remaining trench area (8) above the filling material. <IMAGE>
Patent DE-3806466-A1 (DE)
Inventor: ILLUM NILS
IPC: B41F31/14
Filed: 1988-03-01
Abstract: Arrangement for dosing the supply of a liquid, in particular damping solution or ink, to the printing plate cylinder of an offset printing press. Damping solution is conventionally supplied to the printing plate cylinder of an offset printing press either by film damping systems without ductors or by spray damping systems. The film damping systems do not permit selective, variable adjustment of the supply of solution to relatively narrow areas; in the case of spray damping systems, the image of the jet is often visible on the printed image. An adjustable supply of ink to individual areas is obtained using rollers subdivided into separately adjustable partial rollers. These damping systems are expensive andprone to failure. The new arrangement is simple and reliable and ensures a uniform, easily reproducible supply of damping solution or ink, even in small quantities and different from one area to another, to the printing plate cylinder. This is achieved by the use of a roller with an elastic casing, the diameter of which can be varied from inside the roller by a fluid or gaseous hydraulic medium supplied in a controlled manner from the exterior.

Title: Method for threat analysis for an army anti-aircraft system
Inventor: ANDRE DIETER DR RER NAT
IPC: F41G5/08
Filed: 1988-05-31
Abstract: In the case of the fire-control calculation in the command vehicle of the battery command loop of an army anti-aircraft system, the threat analysis makes optimum target assignment proposals and target returns, with the allocation of engagement areas, on the basis of the air situation, the engagement quality of the weapon systems, and the tactical rules. In this case, in contrast to the situation in the past, the engagement area is not assumed to be the circular weapon effectiveness area assigned to each weapon system but the system furthermore takes into account the fact that each weapon system (WaSystl) possibly has available only a sector (S1) of this area as an engagement area. The method according to the invention can be used in the case of army anti-aircraft systems. <IMAGE>
Patent DE-3821717-A1 (DE)
Title: Loading truck
IPC: A01D90/04
Filed: 1988-06-28
Abstract: For the simple production and power-saving operation of a cutting frame of a loading truck, the said cutting frame being movable into a lateral trailing position, it is proposed to design the cutting frame so as to be pivotable out of the free space underneath the loading truck on a lateral pivot bearing. As a result of this pivotability on a lateral pivot bearing, very low operating forces are to be achieved. Moreover, the outlay in terms of construction is very small. <IMAGE>
Patent DE-3828828-A1 (DE)
Title: Motor vehicle rear axle
Inventor: WINTER INGO DIPL ING
IPC: B60G21/05
Filed: 1988-08-25
Abstract: In hitherto usual composite link rear axles the wheels, under the effect of lateral forces, go more or less markedly into >>toe-out<< owing to unavoidable axle elasticity, as a result of which the vehicle has a tendency to over-steer. In order to reduce or even reverse this tendency, track-correcting bearings are frequently used as link pivot bearings. The new composite link rear axle is intended to produce a >>toe-out tracking<< of the wheels even without such track-correcting bearings. The longitudinal links, connected to one another in the area of their body-side pivot bearings by a torsionally soft and flexurally rigid transverse strut, are torsionally rigid and designed flexurally soft in response to lateral forces acting on them. On a level with their wheel-carrying axle journal they have a rigid spigot trunnion extending towards the centre of the vehicle, on which trunnion one end of a support link pivotably acts at a distance a from the longitudinal link, the other end of which support link acts pivotably on the transverse strut at a distance b from the longitudinal link which is greater than the distance a. <IMAGE>
Patent DE-3828933-A1 (DE)
Title: Method for monitoring a hydraulic system
Inventor: BURGDORF JOCHEN
IPC: F04B51/00
Filed: 1988-08-26
Abstract: A method for monitoring a brake system is proposed. The brake system is capable of carrying out antilock and/or antislip control. For this purpose it is equipped with an electronic controller. For the purpose of monitoring, a volume and/or pressure pulsation image is acquired by means of a sensor (18) and passed on to the electronic controller (4) via a signal line (19) in the form of electric signals. A volume and/or pressure pulsation image which represents satisfactory functioning of the brake system is stored electronically in the electronic controller (4). The current volume and/or pressure pulsation images which are recorded by the sensor (18) are compared with the standard image stored in the electronic controller (4). In the event of one or more current images deviating from the standard image, a signal which indicates a fault is produced by the electronic controller (4). The method supplies a comprehensive, reliable, cost-effective monitoring, in particular of the pump action. <IMAGE>

Title: Linear rolling bearing and method for its production
Inventor: KIRSCH REINHARD DIPL ING
IPC: F16C33/61
Filed: 1988-09-19
Abstract: Linear rolling bearings are known with two track rails, each of which can be inserted into a receiving groove and between which rolling elements can be arranged. The receiving grooves must here be produced separately for each track rail. For simple production of linear rolling bearings (1), both receiving grooves (4, 5) are formed by a single receiving hole (10); they can therefore be produced in a single operation. <IMAGE>

Title: Processing device for preparing the web end of a roll of a material web
Inventor: SOLLINGER HANS-PETER DR
IPC: B65H19/10
Filed: 1988-10-08
Abstract: There is provided a cutting table 1 with a work surface 8 having a groove 6 with a cutting edge 6', along which the web end is straightened with a smooth straight cut as a result of the movement of a knife 14, with the result that the web end also assumes an exact position. This is fixed in that adhesive forces emanate from the work surface 8, either by means of a vacuum applied on the other side of the work surface or by means of electrostatic forces of attraction. Since the material web is primarily a paper web, electrostatic forces of attraction have a very good effect. The adhesive tape can be affixed to the web end by an automatically movable adhesive-tape rolling device.

Title: Method for producing a double-faced colour-patterned knitted fabric
Inventor: RILLING KURT
IPC: D04B1/10
Filed: 1988-10-18
Abstract: Method for producing a double-faced colour-patterned knitted fabric on knitting machines. Multi-coloured patterned knitted articles can even be produced by conventional knitting methods, but there is a great risk of dropped stitches and jump-offs on account of the thread tensions occurring, particularly in the case of finely drawn patterns or motifs. These disadvantages are to be avoided in the new method. In the new method, in the region of a needle bed necessary for the coloured pattern, a first stitch row is knitted 1/1 with the thread of the corresponding colour, the second stitch row is knitted in a full row, the third stitch row is once again knitted 1/1 on the needles not occupied in the first stitch row and a fourth stitch row is knitted in a full row. Knitting method.
