Title: Large door with textile stretched over horizontal beams - has common spindle compensating for electric cable cords varying revolution rates
Inventor: KNITTEL KLAUS W
IPC: E06B3/01
Filed: 1980-08-29
Abstract: Tiered beams or girders, with flexible material stretched over them, are connected by belts or chains, and moved into an opening or closing position by outside drive units, in a door for closing large openings in industrial layouts. Raising and lowering of the unit is effected by a series of independently operating electric cable cords, with a shared spindle to compensate for different revolution rates. Belts bearing the beams are held at such an interval that parts of the stretched material cannot be clamped into the resultant spaces, and the bottom beams act in conjunction with stabiliser devices. These may be box-shaped components, acting in conjunction with guiderails. This can be very tall and wide, with no risk to the stretched covering during raising and lowering, and no need for floor anchorage.

Title: Speed dependent control for engine ignition power - uses alternator supplied additional power, fed to ignition coil or transformer
Inventor: PANEK ROBERT RICHARD
IPC: F02P3/045
Filed: 1980-08-30
Abstract: The control is intended for engines with current supply provided by an alternator. In the engine ignition system is incorporated an ignition coil or a transformer. In addition to the supply voltage fed to the ignition coil or transformer is added a voltage from the alternator, which is speed dependent and rising in proportion to the speed. A frequency dependent voltage transformer element has a series connected rectifier for adding the alternator voltage to the ignition coil supply. The polarising of the rectifier actually transmits the additional d.c. voltage to the ignition coil. The voltage transformer may be formed by a frequency filter with a three-phase transformer coupled to the alternator. To its secondaries are series-connected capacitors. Alternately a resonance element, coupled between the alternator voltage outputs and the rectifier inputs may be used for this purpose.

Abstract: The chuck for a drill with a body (3) with an externally threaded top (10) for insertion into a holder of a drilling machine, has a circular hole (4) at the bottom, for the drill shank (21). Between is a circular part (5) of a smaller diameter, which is divided into sections by slots (7) across it, enabling it to be locked onto the shank when compressed. The top (23) of the shank is square, to prevent rotation, and an adjusting screw inside the chuck can be rotated to apply pressure to this end. This enables the drilling depth to be adjusted as required. The region above the slots has two flat faces (26) which grip the square part between them. The slotted end is compressed by pressure on its sloping external surface (2) when locked in position inside the drilling machine holder.
Patent DE-3034284-A1 (DE)
Inventor: HUEBNER MAX
IPC: A23B4/28
Filed: 1980-09-11
Abstract: In an injection-pickling machine (1) the travel of the injection needles (5) which move in an oscillating manner is varied in accordance with the thickness of the pieces of meat (3, 4) to be treated. In a drive, which consists of a crank lever (25) and a connecting rod (26), to impart an oscillating motion to the needles, the end of the connecting rod (26), e.g. in order to adjust the travel, is hinged on a hinge block (27) which can be moved along a pivoted lever (28). One end of the pivoting lever is mounted in a pivoted manner in a bearing (30) and the other end, which moves up and down, of the pivoted lever is linked to the injection needles (5) via a linkage member (31). For the purpose of adjusting the travel, the hinge block (27) is moved along the pivoted lever (28) by a motor (34) by means of a threaded spindle (33). If the distance between the hinge block (27) and the bearing (30) is small, the travel of the injection needles is large, decreasing as the distance of the hinge block from the bearing increases. The servomotor (34) for the threaded spindle (33) is controlled by a device which scans the thickness of the pieces of meat and which consists, e.g., of a scanning roller (40) at the end of a pendulum arm (41) and a potentiometer (42). <IMAGE>

Title: Surface of bearing ring is plastics coated - by spreading powder then heating under pressure
Inventor: ELGES HARTMUT
IPC: B29C70/78
Filed: 1980-10-10
Abstract: A method of lining the bearing surface of a bearing ring, esp. the outer ring of a pivoting thrust bearing, consists of applying powdered plastics pref. a PTFE-polyester mixt. onto this bearing surface, then applying heat and pressure to compact and bond it to the surface. Pref., the bearing surface is previously roughened. Sintering may be carried out after the powder is applied, or already sintered plastics powder may be used. In partic. a mould corresp. to the negative form of the bearing ring is used to form the coating. This mould may itself be the complementary component of the bearing ring. The method is simpler than that of using a plastics, esp. PTFE foil applied and fused onto the surface.

Title: Method for the disassembling and assembly of gearbox, clutch and engine units
Inventor: HOENEMANN RUDOLF
IPC: F16D13/50
Filed: 1981-06-11
Abstract: In order to reduce the space required for the replacement of a clutch in a motor vehicle and hence also the spaces needed for installation of the gearbox, clutch and engine units, the clutch is detached from the flywheel of the engine and the gearbox from the latter, so that gearbox, clutch and the clutch disk provided on the gearbox input shaft can be disassembled from the engine as a constructional unit and also reassembled in a similar way. A method of disassembling or assembly of this type has the advantage that the required distance by which the engine unit and the constructional unit comprising the gearbox, clutch and clutch disk have to be separated from one another is shortened by the extent to which the gearbox shaft projects into the overall axial dimensions of the clutch when the clutch is fitted on the flywheel.
