Patent DE-3809494-A1 (DE)
Title: Apparatus and method for handling compression springs
Inventor: WAGNER GUENTHER DIPL ING
IPC: B21F3/00
Filed: 1988-03-22
Abstract: Compression springs, which, as randomly ordered parts, become entangled in one another, have hitherto been separated manually or by means of air-blast disentangling apparatuses. The new method is intended, with the aid of suitable devices, to maintain the order present in the production of the spring, until the said part is processed further. The parts can also be supplied individually and automatically at the correct time and in the correct position. In production, compression springs are produced from an endless wire of small diameter and placed in a container as a continuous strand by means of an apparatus. During further processing, the continuous strand is fed to an apparatus which removes the central wire and delivers the springs individually at a defined point. The method is intended for use in the automatic installation of compression springs and for automatic feeding of the springs to spring-end grinding machines.
Patent DE-3826829-A1 (DE)
Title: Suspension for a vehicle seat
Inventor: SAKAMOTO TAKAO
IPC: B60N2/52
Filed: 1988-08-06
Abstract: The suspension for a vehicle seat, having a lower frame (11) which is mounted on the vehicle, an upper frame (12) on which the seat is mounted, a vertically extensible/contractable mechanism, for instance a pair of X-shaped linkages (13a, 13b) which is arranged between the lower frame (11) and the upper frame (12), and a flexible damping element (31) for limiting the lowering range of the upper frame (12). The flexible damping element (31) is arranged such that it lies opposite the movable end portions of a vertically extensible/contractable mechanism. A force directed vertically onto the seat is transmitted as a horizontal load via the vertically extensible/contractable mechanism to the flexible damping element (31). This leads to a reduction in an impact which occurs when the upper frame (12) is lowered onto the lowermost plane, and causes the seat to be set down gently. <IMAGE>

Title: Process for thermal disposal of waste materials containing elements which pollute the environment
Inventor: WEIGEL HORST
IPC: C10B53/00
Filed: 1988-09-06
Abstract: For the thermal disposal of waste materials containing elements which pollute the environment and mineral constituents, such as, for example, ashes, sewage sludge or the like, with fusion of the materials, it is proposed according to the invention to adjust the composition of the starting blend of the waste materials which are to be fused in such a way that the elements contained in the waste materials and polluting the environment are converted into mineral compound and are immobilised in the melt, so that they are sufficiently resistant to elution in neutral and acidic aqueous media, that is to say that the capacity of the melt for leach-resistant immobilisation of the elements polluting the environment is kept very high. <IMAGE>

Filed: 1988-09-09
Abstract: The closable container consists of a container body (1) made of a hard plastic and of a covering (2) for covering the opening of the container body, which covering is likewise made of a hard plastic. Provided in the container body (1) and/or the covering (2) in the contact region is a seal (3) which is integrated in the container body or the covering and is in sealing contact with the respective other element. The closable container thus has fewer parts and can be handled more easily. <IMAGE>

Title: Circuit arrangement and control method for a power inverter having impressed intermediate-circuit voltage
Inventor: STILL LUDWIG DIPL ING
IPC: H02M5/45
Filed: 1988-09-13
Abstract: There are known power inverters which have two branch pairs connected in series between the poles (P, N) of an intermediate circuit, the branch pairs each consisting of a triggerable and resettable semiconductor switch (G1, G2) and an antiparallel-arranged reverse-power diode (D1, D2). In order to reduce the harmonic currents, it is proposed to connect the common connection point of the two branch pairs, which point forms the AC voltage terminal (A), via a branch pair consisting of two antiparallel-arranged thyristors (T1, T2), to the mid-point (M) of the intermediate circuit, which produces a 3-point arrangement. For using the power inverter in a three-phase rail vehicle, the mains-protection thyristors of a four-quadrant controller are connected to the mid-point of the intermediate circuit. The releasing of the thyristors is carried out, observing their hold-off intervals, by triggering and resetting the triggerable and resettable semiconductor switches. <IMAGE>

Title: Device and method for the automatic dosing of dry pigments into a concrete or mortar mixer
Inventor: BAUER KLAUS-DIETER
IPC: B28C7/04
Filed: 1988-10-07
Abstract: A device for the automatic dosing of dry colouring pigments as concrete or mortar additive has essentially the pigment drum in the form of a storage silo and an outlet pipe (8) which can be connected to a storage container (6) for the colouring pigment. The outlet pipe (8) conducts the colouring pigment via a coarse dosing (14) and a fine dosing (16) system into a weighing container (18). From the weighing container (18), the colouring pigment passes, after dosing has been carried out, into a conveying device (30), from where the weighed or dosed pigment is conveyed pneumatically via a tube (36) to the desired consumer. The outlet hopper/weighing container/transport vessel connections are enclosed. Pigments which are difficult to convey are conveyed with sand as transport aid. The device prevents the escape of pigment dust and thus works without damage to the environment. <IMAGE>

Title: Heat treatment process for improving the resistance of hardenable steels of high chromium content to pitting and intergranular corrosion by the application of double hardening
Inventor: STUEDEMANN HANS DR ING
IPC: C21D6/00
Filed: 1988-11-09
Abstract: In a heat treatment process for improving the resistance to pitting and intergranular corrosion in hardenable stainless steels highly alloyed with chromium, the object of double hardening is to reduce, by diffusion, the concentration of alloy elements enriched around the carbides during the first hardening, as compared with the matrix. At the same time, owing to the lower hardening temperature of the second hardening, the precipitation of carbides during cooling in gaseous media can also be prevented or reduced.

Inventor: AHLBORN GUENTER
IPC: B61F5/30

Abstract: The invention relates to the connection of two running gears with multiple axles to a group of running gears for railway vehicles with low-lying loading bridge (10), the running gears having at least two wheel sets (4) of small wheel base and a running gear frame, comprising side cheeks (1) and transverse beams (2) between two axles in each case, the wheel sets (4), being fixed in the running gear frame by means of axle bearings (3) and each running gear being connected to the loading bridge without king pins, merely by means of in each case a laminated bearing spring (6), lying longitudinally at the side in front of each side cheek (1), and a link suspension. The object of the invention was to combine running gears of the type mentioned at the beginning into groups of running gears and to arrange them underneath the vehicle frame or the loading bridge (10) in such a way that the exact turning angle of each running gear and of each group of running gears when travelling around a bend is ensured without enforcement and that an exact axle load balancing of the running gears of each group of running gears is ensured. This object is achieved by the running gears of each group of running gears being connected to one another by a connecting beam arranged in the longitudinal centre of the running gears and mounted on them in a jointed manner, the connecting beam (13) being arranged centrally with play between guide brackets (14) of the loading bridge (10). In this arrangement, the facing ends of each laminated bearing spring (6) of the running gears of each group of running gears are connected to each other via their links by a compensating lever, which is mounted on a bracket of the weighing bridge. <IMAGE>

The working direction of a vibration remover is horizontal, and the dampening body is a ball. The recoil pressure is formed by angled surfaces on the inner wall of the housing, tapering downwards and inwards to a preset acute angle at the housing centre, for the ball to roll. The dampening body can be quadrilateral or cylindrical body, connected to opposite walls of the housing by springs in the working direction (W), with a given spring characteristic. The body can also be connected to one housing wall by a given spring type, and by a piston/cylinder assembly to the other housing wall.
