Title: Method for the production of a reinforcing element
Inventor: BUCHER FRANZ
IPC: E04C5/02
Filed: 1988-07-26
Abstract: Reinforcing elements with at least two parallel reinforcing bars (1, 2) are welded together in contact with one another by means of pieces (8) of wire inserted between them, which melt to form welding beads (7). In order to remove each resolidified welding bead (7), either the supply (3) of wire is pulled back (Z1) before the next advance of the reinforcing rods (1, 2), the insertion device (5) for the supply (3) of wire accelerated (Z2) in the feed direction (A) of the reinforcing rods (1, 2), or the reinforcing rods (1, 2) pulled back (Z3) counter to their feed direction (A). This prevents bending of the reinforcing element despite the jerk associated with the breaking off of each welding bead (7). <IMAGE>

Title: Gearing with one or more simultaneously acting constant transmission ratios, preferably reduction ratios
Inventor: BACHMANN OTTO DIPL ING
IPC: F16H49/00
Filed: 1988-09-02
Abstract: In a gearing for machine construction, one or more simultaneously acting reduction ratios of up to i = 200 and a multiple thereof are achieved with high efficiency, with an uncomplicated, lightweight and quiet-running construction by virtue of the fact that an endless annular band (6) embodied as a toothed belt with different toothings (19, 20) or an endless annular band (6) with a profiled inner surface (1) which, by virtue of its cross-section, has different effective diameters, is non-positively connected to two or more coaxially, independently mounted gears (1, 2) or internal gears with smaller or larger effective diameters, so that these gears (1, 2) or internal gears execute relative rotations when a roller (7) mounted on a revolving eccentric (15) or a plurality of rollers secured on revolving web run round the inside of the annular band (6). In this arrangement, radial incisions (24) allow the annular band (6) to execute an elliptical orbit. The annular band (6) can also be designed as a link chain, the links of which have teeth which roll on the circumference of the smaller of the two coaxially mounted gears (1, 2). <IMAGE>

Title: Flying object as a harvesting apparatus, and a method for stabilising the flying object
Inventor: TEMPLE BERNHARD E R J DE PROF
IPC: B64C31/024
Filed: 1988-09-22
Abstract: The invention relates to a robust flying object having vertical take-off and landing characteristics, which is used predominantly as a harvesting apparatus. Using it, fir cones on high fir trees are harvested and collected manually. In addition, the seeds of deciduous trees can be blown off with it, and items worthy of harvesting are sought over enclosed wooded regions. The inherent flight-attitude stability of the flying object, which is much heavier than air, is based on the vibration-damping effect of a catamaran-like balloon system (5) and a propellor pendulum (2), which is equipped with a control surface (8) and is combined with a heavy and long pilot's pendulum (1). All flight manoeuvres in order to harvest or blow off fruits on trees are carried out using the steerable air jet which is produced by a drive motor (6) and a single airscrew (7). The flying object lands in inaccessible terrains, is of relatively simple construction and therefore has much lower operating and maintenance costs than a helicopter which, as trials have shown, cannot be used for this purpose. <IMAGE>

Title: Switching piece for a vacuum switch, and a method for producing such a switching piece or a correspondingly procured component
Inventor: EGLI WALTER
IPC: C23C24/10
Filed: 1988-12-21
Abstract: The switching piece for the vacuum switch is formed from a contact support (1) made of a material such as copper having a good electrical heat-dissipation capability, on which an arc contact layer (2) is applied consisting of a material having a lower heat-dissipation capability, such as chromium or tungsten. The melting behaviour and vapour-sealing behaviour of such a switching piece are intended to be improved so that a vacuum switch constructed using it has a high dielectric strength after the current zero crossing. This aim is achieved in that the arc contact layer (2) has a thickness (D) in the case of which the melting depth during a switching process is reduced as a result of the increased heat dissipation through the contact support (1), and the cooling-down of the surface is accelerated with respect to a switching piece in the case of which the arc contact layer (2) is so thick that the contact support (1) has no significant influence on the melting depth and cooling-down of the arc contact layer (2). <IMAGE>
