Title: Track laying vehicle with hydraulic tensioning device
Inventor: ILLIAN HARTMUT DIPL ING
IPC: B62D55/30
Filed: 1982-10-08
Abstract: The track laying vehicle has a hydraulic tensioning device for the tracks (1). The tensioning device contains a valve arrangement which keeps the hydraulic pressure in the chain tensioning cylinder (10) between a pretensioning pressure (p0) and a maximum admissible pressure (pmax). In order to be able to implement a plurality of pressure limits (pzul a, pzul b, pzul c), the valve arrangement has in one embodiment a plurality of pressure limiting valves (18a, 18b, 18c) which are connected to the chain tensioning cylinder (10) and whose pressure limits are adjusted in correspondingly different ways. At the same time, in each case one switch-off valve (23b, 23c) driven by a traction switch (21) is connected upstream of the pressure limiting valves (18b, 18c) which are assigned to the pressure limits (pzul b, pzul c) located below the maximum admissible pressure (pmax). In  a different embodiment, the valve arrangement has a separate pressure limiting valve (38) which can be adjusted by corresponding signals of the travel range switch (21) at any time. <IMAGE>
Patent DE-3241970-A1 (DE)
Title: Process and magnetic separator for the magnetic separation of particles
Inventor: GOOD JEREMY ANDREW DR
IPC: B03C1/035
Filed: 1982-11-12
Abstract: Process for the separation of relatively magnetic particles from relatively non-magnetic particles, in which a mixture of magnetic and non-magnetic particles can fall freely, at least under the force of gravity, in a three-dimensional stream on a common path near a wall of a channel S in the vicinity of the magnet 10. The magnet is arranged and constructed such that it generates a strong magnetic field in a horizontal direction, the horizontal component being greater than its vertical component which is smaller than the force of gravity. The free fall of the particles is interrupted when they pass near the magnet, in order to cause them to move away from the magnet, whereupon the magnetic particles are drawn in again by the magnet, while the non-magnetic particles are no longer diverted from their deflected path. The invention also provides a magnetic separator with elements to deflect the particles from the magnet. <IMAGE>

Title: Process for producing aseptic pure water
Inventor: MARQUARDT KURT
IPC: C02F1/78
Filed: 1982-11-26
Abstract: To produce aseptic pure water, a vacuum degasifier is used which reduces to a minimum the microbes contained in the water which is to be treated. To maintain the aseptic state, in cases where there is a low consumption or during shutdown or if there is a relatively large requirement for internal water quantities, care must be taken to maintain the aseptic state of the water, for example by providing downstream a reservoir under reduced pressure through which the water continuously flows. Conventional treatment plants which are operated with ion exchangers or reverse osmosis units can be converted for the production of aseptic pure water by the use of a vacuum degasifier. The pure water treated in such a manner satisfies the highest requirements, for example of the pharmaceutical or electronic industry.
Patent DE-3246790-A1 (DE)
Title: Crankshaft-hardening device
Inventor: FEUER DIETER
IPC: C21D9/30
Filed: 1982-12-17
Abstract: The invention relates to a device for hardening crankshafts, such as are used, for example, in internal-combustion engines. The aim here, is to heat the portion to be hardened to the hardening temperature uniformly and subsequently to cool it uniformly. The problem is that the crankshaft journals are not concentric with the shaft journals. The crankshaft consequently cannot be clamped in a conventional lathe. According to the invention, there is provided a crankshaft-grinding machine, on the machine bed of which a burner and a spray device are mounted. Crankshaft-grinding machines are in any case present in engine repair shops and are therefore cost-effective. Their design as a hardening device as a result of the installation of the burner and spray device does not signify a high outlay. The invention therefore permits an inexpensive hardening of crankshafts.

Title: Insulation-stripping pliers
Inventor: KLOSE ODO PROF
IPC: H02G1/12
Filed: 1983-03-08
Abstract: Automatic insulation-stripping pliers are proposed which have two handles and two intrinsically rigid clamping jaws which can be pressed on to the conductor insulation. The first clamping jaw is an integral part of the first handle and, with said handle, forms an apparatus body on which the second handle is held, such that it can pivot, by means of an associated bearing journal and, furthermore, the second clamping jaw is also held, at a distance therefrom, such that it can pivot by means of a pivoting bearing. Arranged within the two clamping jaws are a pair of cutting and insulation-stripping jaws which are held apart from one another by means of a spring element and are connected in an articulated manner to an operating element which displaces both together in the longitudinal direction of the clamping jaws. The first handle is assembled from two half shells as a hollow body and holds the first handle inside it, with guidance at the same time. Both handles run parallel to one another and together form a pistol grip which is long and wide at the same time, and can be gripped well. The insulation-stripping pliers have the shape of a pistol with a pair of handles which are bent away in a truncated manner opposite the pair of clamping jaws. The pliers are of light construction and consist of glass-fibre-reinforced polyamide.

Patent DE-3319294-A1 (DE)
Title: Gate
Inventor: REJC GABRIJEL
IPC: E06B3/80
Filed: 1983-05-27
Abstract: A gate is disclosed, which consists of a gate leaf with all-round frame. The frame is constructed of two sections, one of which is rigid and inflexible, the other of which is flexible, and further serves as mounting for a flexible gate filling. However, this flexibility only comes into play in the event of the action of a force greater than a given value so that damage by transport vehicles driving against the gate is excluded, but on the other hand the gate, in the closed state, cannot be opened by muscle force. Access of unauthorised persons is thus prevented.

Patent DE-3330015-A1 (DE)
Title: Universal seal
Inventor: HART JAMES E
IPC: F16J15/10
Filed: 1983-08-19
Abstract: A universal seal has at least one surface which is provided with a high concentration of sealing beads in order to attain a high load-bearing capacity per unit area and a seal which is effective in all directions between channels at the interface of adjoining plate parts. The highly concentrated sealing beads are arranged in a regular grid-shaped pattern of interconnected triangular or square closed geometrical figures. The maximum dimension between the beads of a predetermined geometrical figure is less than the minimally acceptable dimension of a surface which has to be sealed against leakage of a flow medium pressure. A seal of this type designed in standardised form produces an effective seal irrespective of differing channel forms, because at least one continuous sealing path is formed in one direction or other or in a path which has a plurality of seals.
