Patent DE-3434878-A1 (DE)
Title: Load projectile
Inventor: LEEKER JUERGEN DIPL PHYS
IPC: F42B12/62
Filed: 1984-09-22
Abstract: Warheads 12 arranged in layers and stacked one above the other in a column-like manner are transported over a target zone by a spin-stabilised load projectile and are ejected there. Because of a differing radial spacing, a differing centrifugal force acts on the warheads 12 and, during the ejection process, leads to sharply deviating flight attitudes of the warheads which are to encounter the target zone in a specific preferred attitude. This disadvantage is overcome in that a rigid connection between the warheads 12 stacked one above the other in a column-like manner is made by means of a disc 17, so that the warheads 12 are first ejected as a warhead layer 12' before they separate from one another. <IMAGE>

Title: Multispeed gear hub for bicycles or the like
Inventor: BERGLES EDUARD ING
IPC: B62M11/16
Filed: 1984-11-02
Abstract: The invention relates to a multispeed gear hub for bicycles or the like, having a gear shift in which a planetary gear can be engaged by means of a locking catch system, and the shifting of the locking catches being capable of being controlled by axial displacement of at least one coaxial component via a shifting block, such that the axially displaceable component is constructed as a shifting ring and is elastically coupled to the shifting block and such that, as a result, the driver can alternately be coupled either to an axially securing coaxial planetary wheel carrier or to the associated hollow wheel which is arranged so as to be axially displaceable counter to spring stressing. By means of this design, a multispeed gear hub for more than three speeds and having a back-pedalling brake device is obtained. The gear shift is carried out here with a single shift element from one side of the hub axle. The back-pedalling brake acts independently of the respective shift position of the hub gear with unchanged braking force (Fig. 1). <IMAGE>

Title: Vehicle wheel with improved emergency running properties
Inventor: HOWIND VOLKER
IPC: B60C17/04
Filed: 1984-12-20
Abstract: The invention relates to a vehicle wheel with bound beads of its pneumatic tyre, the zenith part of the tyre being supported during emergency running on a counter bearing between the beads. In order to ensure that the tyre can still transmit considerable forces even during emergency running without having to fear premature destruction of the tyre, according to the invention the binding of the beads can be eliminated at certain points by means of an axial and/or radial adjustment of the wheel body or of the parts of the wheel body which bring about the binding of the beads. This adjustment takes place as a function of the internal pressure of the tyre. Expediently, the binding of the beads is effected with a ring on which the tyre rests laterally on the outside and can be displaced laterally outwards for the purpose of releasing the binding.

Title: Piston pump without inlet and outlet valves
Inventor: BUECHNER HEINZ
IPC: F04B53/12
Filed: 1985-08-16
Abstract: The advantages of the piston pump without inlet and outlet valves compared to the conventional one- or two-valve pumps are obvious and include the following points:   1. Because the mechanical conventional valves are dispensed with, simple and extremely small pump bodies can be manufactured. 2. The uncomplicated casing bodies have a beneficial effect on the cost of manufacturing the tools required for production. 3. Because the mechanical valves are no longer present, the susceptibility to faults is considerably reduced, which in turn results in a reduced potential maintenance effort. 4. Because of the possibility of a presettable water-stop function without additional booster valves, there is a further not inconsiderable cost reduction in manufacture, especially for long-stroke, high-capacity pumps. 5. Owing to this additional possible water-stop functionality, the appliances can be started when water discharge has been stopped, without overloading the motor. As a result, the water discharge can be started from the nozzle holder by pressing a button or pushing a lever, and the intensity of the water jet can be regulated or controlled. This possibility obviates a regulating device at the appliance itself, and thus a sometimes complex mechanism, which contributes to a further cost reduction in manufacture. t

Patent DE-3543690-A1 (DE)
Title: Device for vulcanizing or for cross-linking profile strands produced from elastomers
Inventor: REIMANN GEORG DIPL ING
IPC: B29C35/04
Filed: 1985-12-11
Abstract: In continuous devices for the pressureless vulcanization of profile strands under the effect of microwaves, the hot air flowing around the strands becomes enriched with evaporating plasticizer proportions and must therefore either be cleaned for reuse or, in the case of exhaust-air operation, the plasticizer must be subsequently burnt off. In view of the large quantities of air required, relatively extensive post-treatment systems are necessary for this. According to the invention, the volume, through which the profile strands pass, of the devices is split up into a smaller air current flowing directly around the strands and a larger air current indirectly surrounding them. As a consequence of this the quantity of air to be post-treated is much lower, so that the capacity of the post-treatment systems can be considerably reduced.
