Patent DE-2408565-A1 (DE)
Title: Spring winch with breakage protection - has drum catch normally held retracted by spring engaging with housing ribs
Inventor: HEINEMANN ALBERT
IPC: B66D5/00
Filed: 1974-02-22
Abstract: The winch is particularly for handling heavy tools, the spring counteracting the weight of the load on the rope. To protect against spring breakage there is inside the periphery of the drum a pivoting catch, with which the outer end of the winch spring engages so as to hold it in the retracted position. Outside the drum periphery and clear of the retracted catch there are inwards-protruding ribs in the housing. If the spring breaks the catch swings outwards and engages with one of the ribs. A recess can be provided in the drum to accommodate the catch, which can have a chamfer working with a mating ramp face in the drum recess.

Title: Dislocation-free (silicon) semiconductor monocrystal prodn. - with low carrier lifetime zones by hole and recombination centre prodn.
Inventor: KELLER WOLFGANG DR
IPC: C30B31/06
Filed: 1974-05-07
Abstract: In the prodn. of dislocation-free semiconductor monocrystals, esp. of si, with zones of low carrier lifetime, zones with an elevated hole density are formed first by partial destruction of the crystal lattice and then defects of foreign atoms forming recombination centres are diffused into the lattice. alternatively, the foreign atoms are diffused into the crystal first and then partial destruction of the crystal lattice is carried out. The zones of elevated hole density can be produced by irradiating the crystal lattice with high-energy particles, pref. non-doping ions, esp. nitrogen, rare gas and/or halogen ions, alpha rays or neutron radiation, using an absorber screen, esp. of Cd, Gd or B, or high-energy x-rays, with a Pb screen. Alternatively, these zones can be produced by non-crucible zone melting of a Si monocrystal by the use of a strong radial temp. gradient at the solid/liquid phase boundary. Starting material for special integrated power elements with zones of varying carrier lifetime can be made reproducibly.

Title: Absorber of solar radiation energy - consists of pipe surrounded by transparent sheet of glass or plastic
Inventor: LOBSCHAT HELMUT
IPC: F24S10/40
Filed: 1974-08-14
Abstract: The absorber is formed by a pipe or tube (2) which has a matt black coating on the outside to absorb radiation. It is supported on a slab (3) of hygroscopic insulating material and surrounded by a semi-circular sheet of transparent material (1) which allows solar radiation to pass through it but does not transmit low temperature radiation from the pipe. There is an air gap between the pipe and the transparent sheet. The insulating slab is hygroscopic in order to absorb any condensation occuring in the air gap. The circular construction enables radiation to be absorbed equally efficiently at all angles of incidence and therefore at all positions of the sun throughout the day.

Title: Concrete building component reinforcing mesh layer spacer - with end footed loops, one V bent, and resistance spot welded at inter-sections
Inventor: MERRETTIG PAUL
IPC: E04C5/18
Filed: 1974-09-04
Abstract: In the interval-preserver for reinforcing-inlays in concrete building components, esp. for maintaining the distance between two superimposed reinforcing meshes, there are two loop shackles (1, 2) which intersect, or which are in contact with each other, in the interior of the spacer, one of these being bent into a V shape at any appropriate angle. These shackles have feet (3) at their outer ends, directed towards the surface on which they are being set up, and the one which is not V-bent also has a foot (4) at its inner end directed towards this surface. Where they come into contact with each other (5), the two shackles are connected by resistance spot welding. The varying height of the spacer is determined by the length of the feet and the loop shackles may be made of wire.

Title: Reverberatory furnace for melting scrap metal - collects hydrocarbon emissions and supplies them to the gas burners
Inventor: HABAYEB KHALED M
IPC: F27B17/00
Filed: 1974-12-10
Abstract: Reverberatory furnace has bottom, end, top and side walls with a melting chamber portion in the lower region. The chamber portion extends beyond the second end wall to form a charging well. The first end wall has a discharge stack from which combustion products leave the furnace. The gas burners are also mounted in the end wall. An enclosure surrounds the charging well and includes a dome for collecting hydrocarbon emissions given off by contaminated metal charged into the charging well. The emission together with air are drawn through the duct and conveyor to a blower then to the gas burners as combustion air. The hydrocarbons are completely burned and the solids passing from the furnace via the stack are small. Metal is charged into the furnace from a lift truck or the like which passes through an opening in the enclosure. An air curtain prevents the escape of emissions from the enclosure via the opening. Atmospheric pollution is reduced and the hydrocarbonsemitted are converted into useful heat energy.

Title: Fly wheel powered transmission - has movable bearings to reduce friction on shafts when stationary
IPC: H02K7/02
Filed: 1975-03-17
Abstract: The flywheel transmission has two sets of flywheel assemblies in a common housing and supported on movable bearings. These can be relaxed when the vehicle is stationary to reduce the drag on the flywheel support shafts, and tightened to brace the flywheel suspension when the vehicle is moving. the flywheel is run up from an external shaft by a friction coupling through coupling flanges. The two flywheels rotate in opposing directions and are linked by electric motor/generators which equalise the rotational speeds of the two wheels and provide a stable system. Epicyclic gearing couples the flywheels and the transmission, with the gearing mounted in the same housing as the rest of the system.

Title: Candle wick erecting tongs - for subsequent gripping of wicks by clamps prior to candle dipping e.g. for colouring
Inventor: HERRHAMMER ALFRED
IPC: C11C5/02
Filed: 1975-07-23
Abstract: The candle wick-erecting device can pivot in either direction on its axial journals.

Title: Positive-displacement vacuum pump for liq. filter - preventing inadequate vacuum due to dry running
Inventor: MILLER PETER ANTHONY
IPC: B01D29/09
Filed: 1975-10-16
Abstract: Vacuum pump appts. for a chamber-type liquid filter consists of a single positive-displacement pump which is provided with a collecting tank on the pressure side of the pump. The collecting tank is arranged in such a way that liq. is always present on the suction side of the pump by force of gravity and be means of a suitable pipe which allows partial return of the filtrate. In this way the pump is always provided with sufficient lubricant or sealing liq. This system avoids the disadvantages of conventional positive-displacement pump systems in which due to wear, dry running of the pump cannot be carried out, or due to the presence of dead space, dry running of the pump does not generate an adequate vacuum.
