Title: Metal dosing scoop, esp. for pressure or gravity die casting - where tiltable scoop can be moved horizontally and vertically between furnace and die casting machine
Inventor: BOLLAND OTTO DIPL ING
IPC: B22D39/02
Filed: 1979-03-26
Abstract: Vertical bar with a hexagonal cross-section can be driven vertically in a trolley which can be moved horizontally along a rail or girder. On the top end of the hexagona bar is a compressed air cylinder with its piston rod moving an axial rod to tilt a pouring and dosing scoop mounted on a pivot at the bottom end of the bar. Rod is fitted with an adjustable and spring-loaded limit stop which controls the angle through which the scoop is tilted and therefore amt. of molten metal pured from the scoop into a die etc. After supplying the dose, the scoop is pref. titled slightly towards the upright position before returning to a furnace to collect more molten metal.

Title: Motor for electrically driven vehicle - has inner and outer permanent magnets on drive shaft and armature windings between
Inventor: TESCH WERNER
IPC: H02K29/00
Filed: 1979-06-07
Abstract: The motor for an electrically driven vehicle has inner and outer sets of permanent magnets (1,2) mounted to rotate with a drive shaft (7) through the middle. The outer magnets (1) are mounted inside a cup-shaped carrier (6) and the inner magnets (2) are on a flanged sleeve (5) both mounted on the shaft. Between them are amative windings (3) wound onto radial supports (4) forming segments of the armature supported by a member (9) in the end wall of the housing (8). The flanged end of the sleeve and the outer carrier act as magnetic yokes for the permanent magnets. The windings are fed with pulses to form the drive using remote excitation, and the movement of the vehicle may be used by rotation of the magnetic field around the stator to recharge the batteries when used with a rectifier. The inner magnetic poles can be adjusted in position against the outer magnetic poles.

Title: Friction-twisting open=end spinning appts. - using inclined asymmetric hyperboloidal drums with differential airflow through perforated surfaces
Inventor: SCHIMINSKI HERBERT
IPC: D01H4/16
Filed: 1979-07-31
Abstract: In an open-end spinning device, the fibres are collected on the surfaces of two similarly-rotating perforated drums of asymmetric hyperboloidal form, and friction-twisted into a yarn in the gap between the drums. A suction device within each drum, in the vicinity of the twisting gap gives a suction at the outgoing surface which is four times that at the ingoing surface, pref. in the range 2000-3200 mm water and 200-800mm water respectively. The smallest clearance between the surfaces pref. 0.02-0.1 mm, is smaller than the yarn diameter, and increases in the direction of yarn withdrawal. The speed of the outgoing surface outgoing from the gap is greater than the speed of the ingoing surface by up to 10%. This arrangement gives a considerable saving in air consumption over the design described in the parent appln., whilst producing yarn of comparable quality and also permitting the production of a wide range of counts without necessitating extremely delicate and accurate adjustments.

Title: Solar collector and heat storage unit - has bell-shaped insulating jacket inside similar collector proper and having top and bottom openings to achieve thermo-siphon effect
Inventor: URBANEK AXEL
IPC: F24J2/34
Filed: 1979-12-21
Abstract: The solar collector is spherical or bell-shaped. It offers the same surface area to radiation from the sun no matter what the season or time of day. Its rear side can be undercut or cut back, e.g. for bordering on a wall or roof top. An insulating jacket of matching shape is mounted within the collector or allowed to float on the liq. medium, e.g. water. The jacket is open top and bottom to allow the medium to flow from the internal storage through the tubular intermediate space between collector and jacket to form a circulating system. This occurs through heating and the force of gravity. The medium flows slowly from the top so that a temp layer is formed in which it is heated. The jacket is always approx. 1 mm higher than the liq. medium level so that a current flowing in the opposite direction is prevented.
Patent DE-2954737-A1 (DE)
Title: Packaging staple fibre yarns or tows into bales - of high bulk density by intermediate compression in sacks and final compression in main press
IPC: B30B9/30
Filed: 1979-03-27
Abstract: Staple fibres or fibre tows are packaged into bales in a multi-stage process by intermediate compression of the fibres delivered by a discharge device in a compression container (3), conveying the compressed fibres in package form to a main press (4), which is supplied with compressed fibres from other discharge devices and compressing and packaging the intermediately compressed packages. Bales of high bulk density are produced and manner of packaging prevents contamination of fibres, e.g. by rust from steel tapes, during transport and storage.

Title: Optical information recording system - produces record of sum of projected image and interference raster of laser beam splits
Inventor: PANASJUK LEV M
IPC: G03H1/04
Filed: 1980-01-29
Abstract: The recording system of an optical information consists of projecting the image of an object, carrying the optical information, on a photosensitive thermoplastic carrier. At the same time, a raster grid with interfering beams is applied and the picture produced is fixed. The interfering beams are controlled in such a way that the recorded picture represents the sum of the projected image and of the superimposed raster grid. This creates a method of recording on a photosensitive thermoplastic carrier colour pictures or holograms of objects which are illuminated by non-coherent radiation.

Patent DE-3113992-A1 (DE)
Title: Rowing mechanism for model rowing boats
Inventor: WEDEMEYER ERWIN
IPC: A63H23/04
Filed: 1981-04-07
Abstract: A rowing process is composed in practice of two horizontal swivelling planes of the oar, one above and one in the water, and two vertical planes, namely from the one horizontal swivelling plane into the other. The invention relates to a rowing mechanism in which this sequence of movement is brought about, in a manner close to reality, solely by the reciprocating movement of the rower, produced by the crank disc of an electric motor. The reciprocating movement produces a moment of force in the shoulder joint, resulting in a horizontal and vertical movement of the arms or hands. These are holes and accommodate the oar handles. The oars are mounted on the oar spike (rowlock) using a hole in the shape of an oval funnel. The funnel angle corresponds to the vertical swivelling angle of the oars, this resulting in precise guidance in both horizontal planes. This rowing mechanism is designed as a unit and permits an economic modular construction system. The requirement for force and the speed in the rowing process are variable. A segment on the crank disc actuates a switch which adapts the driving voltage to the intervals of the rowing.

Title: Numerically controlled grinding machine with a dressing device
Inventor: PEROVIC BERLIN DR ING
IPC: B23G1/38
Filed: 1981-07-09
Abstract: In the case of a numerically controlled grinding machine, in particular a thread-grinding machine, the dressing device is, along with the technically simple construction, to be actuable by the numerical control itself. According to the invention, the dressing device itself is thus mounted in a stationary manner on the machine bed, the cross-slide can be displaced on the machine bed to the dressing device in order to move the grinding wheel into the position for dressing with the dressing tool, and the movements required for dressing the grinding wheel are effected by the numerically controlled cross-slide along two numerically controlled pins located at right angles with respect to one another. As a result, the movements required for dressing are carried out by the numerically controlled pins, already existing in the numerically controlled grinding machine, and guides.

Title: Device for producing a duct in bone cement for anchorage of an endoprosthesis
Inventor: BUSCHMEYER RALF
IPC: A61F2/46
Filed: 1981-08-08
Abstract: Numerous special instruments have been specified for removal of cement from the bone shaft on replacement of endoprostheses. However, the development in this field is far from being concluded. The main problem resides in removal of the solid cement plug deep in the bone. Whereas most authors provide windows in the bone shaft in order to reach the cement plug we choose access from the empty prosthesis seating. The forehead lamp serves as light source. We developed the device according to the invention for the purpose. A duct is to be driven into the solid plug along which the commercially available instruments already described can be guided.
