Patent DE-3707768-A1 (DE)
Title: Vacuum heat insulation
Inventor: HENSBERG FRIEDRICH
IPC: E04B1/80
Filed: 1987-03-11
Abstract: Two metal panels are connected at their edges by plastic profiles with a low degree of thermal conductivity, with the result that a vacuum space is fully enclosed between the profiles and the metal panels, in which vacuum space there are located partially interconnected plastic supports with low thermal conductivity which intercept pressure on the vacuum. Located in the vacuum is a very thin fibrous material which extends to the greatest possible extent in the plane of the metal panels and is slightly permeable to radiation heat. The profiles are permanently sealed on their outer side by means of a thin-walled, gas-tight band with low thermal conductivity. This invention achieves an extremely good, cost-effective and permanent heat insulation, in particular for buildings.

Patent DE-3716443-A1 (DE)
Title: Apparatus for collecting seepage water from landfills
IPC: B09B1/00
Filed: 1987-05-16
Abstract: The apparatus serves to collect seepage water from landfills, the landfill body of which is underpinned by a sealing platform. The apparatus has a seal on the upper side and it forms the cover of an accessible monitoring area. In order to collect problematic seepage water, the upper side of the sealing platform is subdivided in the form of a grid. Since the sealing platform itself, however, runs continuously, damaged platform regions can be repaired or exchanged only with great difficulty. The apparatus is thus to be configured such that, in the event of repair, the corresponding regions of the sealing platform can be easily exchanged. The sealing platform is subdivided into individual shaped parts, above which optional carrying elements are arranged. They transfer the load of the body of the landfill, when the platform elements are being exchanged, to neighbouring platform elements. The individual platform elements can easily by exchanged in the event of damage. On exchange, the optional carrying elements located above the platform elements transfer the load of the body of the landfill to the neighbouring platform elements, which therefore do not have to be supported. The apparatus is suitable for collecting seepage water from landfills.

Title: Method for dividing bent round-timber to form curved boards, planks or squared timber
IPC: B27B1/00
Filed: 1987-05-26
Abstract: A method for dividing bent round-timber 1 to form boards, planks or beams which are curved in accordance with the principle curvature of the latter is specified. The known methods require, for their performance, a very high structural expenditure with, in some cases, excessive space requirements, and they do not produce the necessary dimensional accuracy in the cut products. In contrast, the method according to the invention enables, by means of special steps, a wood division of this type or such wood cutting, while using a normal sawing installation for straight cutting of round timber 1 which, in a conventional arrangement for this purpose, has a chipper 3 for lateral flattening of the timber 1, saws 4 for dividing the timber 1, there between a set of rollers 5 for lateral guidance of the timber 1, and aligning-arm pairs 6 for centring the timber 1 ahead of the chipper 3. <IMAGE>

Title: Five-phase synchronous motor with flat airgaps
Inventor: CORNIDES BOLDIZSAR
IPC: H02K29/06
Filed: 1988-12-06
Abstract: The invention relates to a five-phase synchronous motor with flat airgaps, and consequently a high-current machine with high-speed rotor (a multiple of the mains-synchronous revolution speed), and a current converter to form individual drive pulses. The motor is equipped with three main elements having the same diameter: the two heavy field spiders (N and S) made of heat-treated cast steel, on a common flux-conducting shaft (Ft), and the stationary ring armature (A), which is wound from iron strip with the DC excitation winder (G) fastened therein. All the pole pieces (Pn; Ps) of one field spider (N; S) have the same polarity. Winding ends, divided into five phases and labelled with the letters S-Y-N-O-R, are fitted in the radial slots of the ring armature (A). For restricted demands, a mechanical current converter is provided. This has a stationary synchroniser ring and a rotating switch element having sliding contacts. The fully-electronic pulse formation ensures reliable drive with very high precision. On the edge of a synchronously running timing disc, contactless transmission elements which indirectly drive semiconductor switches are fixed. Peak rotational speeds occur as a result of the reduced time constant of the air-cored armature disc (in the form of a flat winding), resting in the airgap of the two field spiders. The rectified mains current is chopped by switching transistors or thyristors into overlapped drive pulses ... Original abstract incomplete.
