Title: Cut staple fibre removal system - has a turbulence-free airstream passing through the radial cutting blades
IPC: D01G1/04
Filed: 1974-02-21
Abstract: The construction of a continuous cutting unit for wound strands of continuous filaments, to reduce them to staple fibres by radial cutting blades to slice through against the pressure of rollers on the strands, has a cut fibre removal system with an airstream through a ring channel leading to openings in the end wall of the cutting unit. The system ensures an efficient extraction of the cut staple fibres between the cutting blades, without developing any turbulence in the extraction path.

Title: Material compression mechanism in mould - has pestle with taper-faced pressure disc rotating on crank pin
Inventor: HAEBERLE WILHELM
IPC: B28B1/04
Filed: 1974-03-22
Abstract: The mechanism particularly for compressing concrete used in the manufacture of slabs and similar components. Each pestle has a rotary pressure disc or plate (23) with a tapered head surface towards the material to be compressed. The disc is inclined, and coupled by a crank (24) to a driving shaft (28). When producing flat slabs, the disc can be so mounted that the surface bearing against the material is always at right angles to the drive shaft axis. Disc and mould can be equipped with servos acting in the direction of the disc axis, typically in the form of jacks. The external form of the pestle can be matched to the internal form of the mould and the disc can run on ball-bearings on the crank.

Title: Bolt connector for circular sections - uses nut and bolt with sealed washer for providing watertight joints in corrugated and circular sections
Inventor: FUCHS WOLFGANG DIPL ING
IPC: E04D3/365
Filed: 1974-04-18
Abstract: The bolt type connector is used for connecting cylindrical water pipes or corrugated sections together. The bolt used has a dished inside head face which fits to the outer face of the pipe section. The bolt shank is fitted with a deep hollow section washer which has a spherical face which fits against the inside of the curved section, the top face is flat and locates against the locking nut. A loose rubber sealing ring which protrudes above the spherical face is fitted inside the washer. When forced against the inside of the curved surface by the action of the nut the rubber sleeve is forced onto the space between the bolt shank and the clearance hole. A watertight seal is thus obtd. between the two sections. An annular sealing ring can also be placed between the two mating surfaces.

A first pair of transport rolls is arranged to grip and transport the sheet with continuous motion response to the leading edge of the sheet being seen by a first reflected light sensor. When the leading edge reaches a second such sensor a sheet stepping device effects stepwise movement of the sheet through the printing station for printing a predetermined number of lines. Thereafter, a second pair of rolls takes over the removal of the sheet from the printing station.
Patent DE-2447220-A1 (DE)
Title: Large propellers and rotors for aircraft - are made from sheet metal layers to prevent spread of local fracture
Inventor: LEHMANN HANS
IPC: B64C27/00
Filed: 1974-10-03
Abstract: To localize fractures in helicopter rotors and large propellers, the rotor blades are manufactured from a large number of metal sheets. At the rotor root, the sheets are stacked together to form a solid shaft. Further out from the root the sheets are spread to form a typical propeller profile. They are held in position by laterally orientated clamping elements. A fracture in a propeller blade element will not spread, thus propeller failure is prevented. The plane of the metal sheets may run clockwise, and steps may be taken to ensure that the propeller blade or rotor blade has a smooth surface.

Title: Electronic control for windscreen washer and wiper - has monostable multivibrator to allow short wipe operation for clearing spray
Inventor: NEUFFER KLAUS
IPC: B60S1/48
Filed: 1975-12-06
Abstract: The windscreen washer/wiper system is controlled by an electronic circuit in which the action of the wipers is retarded for a set time interval to allow the washers to wet the windscreen. This is achieved using an impulse generator. In order to allow instant wiping action to clear a wet screen the washer control is briefly tapped. This operates the wipers for a few wipes only. A monostable multi-vibrator has its inputs parallel to the washer impulses while the output signal begins with the negative slope of the washer pump pulse, and remains for a set period to energise the wiper motor. The system enables the driver to instantly clear the windscreen of spray etc. on fast roads, without having to wait for the delay period in the normal wiping action.

Title: Automatic system to hold boat course in channels - using two alternating phase shifted magnetic fields and detectors on board
Inventor: BALL KENNETH H
IPC: G05D1/02
Filed: 1976-02-27
Abstract: The method is for automatically holding an object such as a boat in a shallow channel on course using two alternating out of phase magnetic fields and suitable onboard detection equipment, and is relatively insensitive to signal amplitude variations. Two long electromagnetic loops (16, 17) are laid along the required path or course of the boat (15), on the bed of channel, to produce overlapping magnetic fields, out of place by 90 degrees when driven with suitable power amplifiers and transformers (41, 42). A power saving link of capacitances (43, 44) and resistances (45, 46) between the loops is also used. On the boat, two detection coils (11, 12) mounted at right angles, detect the overlapped alternating fields and produce signals amplified, (27, 28), fed to a phase detector (31) and used to drive a motor (33) attached to the boat rudder.

Title: Wire length cutting machine - has two discs with interlocking teeth cutting through wire at every revolution
Inventor: HOEWING JUERGEN
IPC: B23D25/12
Filed: 1976-04-26
Abstract: The wire (1) tobe cut, is stored on a coil (2) from which it is removed by a drive at constant speed. The wire is first passed through a straightener (3) after which it runs through a set of cutters (4). The cut wires are fed into a rotating wire holder. After each cut, the holder rotate a step so that a wire can drop into a container (8). The pair of cutters consists of discs which each have a radially extending cutting edge. The two cutting edges face one another. While the wire runs between the discs, the cutting edges are located away from the wire. At a particular point in time, which depends on the required lengths, the discs are rotated and accelerated over half a turn until they reach the same speed as the wire. At this point, the cutting edges on the discs slide past one another and cut the wire.
