Patent DE-2611435-A1 (DE)
Title: Float for water surface hydrofoil - has float set under fuselage in front of wings to use bow wave to shield wings
IPC: B60V1/22
Filed: 1976-03-18
Abstract: The surface skimmer has the fuselage set forward of the main wing and extended downwards to form a floating hull when on the water. The main weight of the craft is supported on the water by the front edn as the speed is increased. The captured air cushion is contained by lateral bulkheads within side floats near the ends of the wing. The fuselage bow wave prevents waves from entering the air cushion. The craft is stable in waves, with the front of the fuselage pushing the waves aside. Spray and waves are detered from entering the air cushion so that a maximum lift effect can be achieved.
Patent DE-2613333-A1 (DE)
Inventor: HINTERMANN MARCEL
IPC: F24B1/188
Filed: 1976-03-29
Abstract: The method and the device serve to reduce the relative air humidity in a room heated with an open hearth fire. For this purpose, air is introduced from outside under pressure into a pipe system (8) lying in the region of the open hearth fire. In this, the air is heated by the fire heat, as a result of which its relative humidity value sinks. At the end of the pipe system, the heated air is delivered into the room again. The pipe system (8) covers a considerable part of the fire area (7) of the hearth, maintaining a distance from the inner hearth floor which is suitable for the supply of the oxygen of the combustion air from below. By means of this device, it is possible to influence the disadvantageous humidity values arising in rooms intended for living in for the better. <IMAGE>

Title: Electrophotographic copying with single-component developer - of high resistance produces clean toner picture and effective transference to paper
Inventor: SUZUKI KOHJI
IPC: G03G15/09
Filed: 1977-02-02
Abstract: An electrophotographic process consists of forming an electrostatic, latent image on a photosensitive component and then developing it using a single-component powder developer containing a single magnetic charge-free toner; a transfer or copying sheet is then brought into register with the visible powder or toner picture so that the picture is transferred onto the copying sheet by applying an electrical charge to the rear of the copying sheet by corona discharge. A single-component developer having an electrical resistance is not 1012 ohm. cm is used; the surface of the photosensitive component, typically a drum, possesses microscopic irregularities. A rotatable, non-magnetic tube contains a stationary magnet and is used for transferring the developer, temporarily held to the surface of the tube by the magnetic action, to the developer station. At the developer station, a magnetic toner brush is applied to the surface of the photosensitive component to cause development to occur. The magnet produces a magnetic flux density on the tube of is not 1,000 Gauss. By utilising a relatively high resistance of 1012 ohm. cm cf. is not 1011), an effective transfer of the developed picture is obtained. At the same time, the quality of the image developed and to be transferred is not impaired by the use of this higher resistance.

Title: Stepless variable speed drive for automobile - has split coned pulleys controlled by irreversible motor powered worm drive
Inventor: FALZONI GIANLUIGI
IPC: F16H37/02
Filed: 1977-06-15
Abstract: The power from the engine of an automobile is transmitted through a shaft and gear wheels to the shaft (4a) which carries the split coned pulley (5). A compression spring pushes the sliding half pulley towards the fixed half pulley and balances the axial component of the force due to the belt (18). The belt is of trapezoidal cross-section and drives a split pulley. The separating force due to the belt is resisted by a spring which acts on the rod (38), provided with a toothed rack which meshes with pinion drive from the electric motor through the worm and worm wheel. The speed ratio between the pulleys is thus controlled by the worm drive which is irreversible so that the speed ratio cannot change if the electric motor fails.

Title: Testing of computer controlled PBX - uses test equipment reading specific system data stored in memory, and derives from them parameters for PBX testing
Inventor: SEHR WERNER
IPC: H04M3/22
Filed: 1977-07-21
Abstract: The PBX extensions specific system data, such as numbers, system constants, call hierarchy etc., are stored in a memory, from which they are read out when required, e.g. for connection build-up. Test equipment, not connected exclusively for the respective PBX, is connected before testing through the PBX busbars to the memory. The data are read out from the memory and analysed by the test equipment. Thus, parameters are derived from the data and are used for activation of test processes required for the PBX in question. If the subscriber dates have not yet been written into the memory, they can be written manually into the tester memory and transfered to the main memory.

Title: Lubricant for rolling lead and tin foil solder - consists of polyglycol, which improves flowability of solder
Inventor: MESS HEINRICH
IPC: C10M107/34
Filed: 1977-09-13
Abstract: Pb or Sn foil, used as solder, is rolled using polyglycol as a lubricant during the rolling process.

Title: Pultruded glass reinforced plastic - coated filaments drawn successively through several pairs of heaters and cool dies and finally reeled
Inventor: STILES KENNETH MARTIN
IPC: B29C70/52
Filed: 1977-12-21
Abstract: Pultruded GRP components are produced by (a) coating numerous continuous filaments under tension with a liquid thermosetting resin at a temp. below its curing temp., and (b) passing them through successive radiant heaters, each with >=1 heated surface, at a distance from the coated material, then through >=1 relatively narrow cold die between successive heaters, the resin being heated each time sufficiently both to reduce its viscosity to below the level at which it entered the heater concerned and also to commence to cure. The coated filaments are drawn through each die and the dies are below the curing temp. At least one die follows the last heater and the resin here (or earlier) reaches its gel point. The process has low energy consumption, and the matl. is cleaned when entering into dies. It is suitable for various fibres and combinations, also for various profiles.
