Title: Clasp for snow chain on tyre - has interlocking hook and eye operated by linked chain pull
Inventor: GLATZ LUDWIG
IPC: B60C27/10
Filed: 1975-08-27
Abstract: The end of one section of the snow chain is fitted with an S-shaped hook (2) with a tensioning chain (4) fitted to the end. The chain is looped through an eye (6) at the other end of the chain section and leaving a length of the tensioning chain (4) for the operator to grip. Pulling the chain clips the two ends of the snow chain together. When in use, the tensioning chain is laid along the side of the wheel and is not subjected to any tension. To release the snow chain the tensioning chain is pulled again at a differential angle. Fitting and removal of the snow chain can be performed in a short time.

Title: Optical system to determine focal plane - produces periodically modulated photo-electric signals and uses pair of interacting diaphragm apertures
Inventor: HOCK FROMUND DIPL PHYS
IPC: G01B11/02
Filed: 1975-08-30
Abstract: The focussing plane determination in an optical system is by producing periodically modulated photo-electrical signals during the movement of an object plane image using pair of interacting diaphragm apertures. Each image of an image pair of the diaphragm apertures is produced by the light of only one diffraction order of the grating without over-lapping adjacent images. The object plane with the moving object (11), for example a moving surface, the sag of which is measured, is illuminated by the light source (14) via the deflection prism (16) and objective (13) which acts as a collimator. The scattered beams pass into the plane of the diaphragm apertures (17, 18).

Patent DE-2621810-A1 (DE)
Title: Multicomponent foam mixing head - having central air vortex generator and needle valve to prevent clogging
Inventor: RASCHI LUDWIG
IPC: B05B7/12
Filed: 1976-05-15
Abstract: Foam gun for producing a multicomponent plastics foam by low-pressure mixing comprises a mixing head, mounted on a support, and containing an air duct and at least two component ducts. Air inlet duct leads to a coaxial needle valve centrally placed between the component ducts. The air inlet duct contains a twist-inducer, for imparting a rotary motion to the air before it reaches the needle valve, and the material ducts each contain a closure member, which is so controlled that is not opened until the needle valve has also been opened. Although initmate mixing of the components and air is achieved, the discharge duct does not become clogged after the gunning operation has been completed. When gunning has been completed, the feed of materials to the mixing head is discontinued, but air supply continues for a short time, thus clearing the ejection duct. Conversely, when starting up, the air supply is first commenced in order to induce a sub-atmospheric pressure in the air vortex causing the materials to be drawn in.
Patent DE-2633608-A1 (DE)
Title: Multi-blade isolating damper for ventilation ducts - has each blade turned by linkage mechanism from operator
Inventor: RUFER PAUL
IPC: F24F13/15
Filed: 1976-07-27
Abstract: The damper has several blades (8,10,12) each turning on its own pivot (2,4,6). An arm (30,32,34) rigidly connected to the pivot is freely pinned to a lever (36, 38,40). The lever is in turn freely pinned to a lever (42,44,46) which has a slot through which a fixed pin projects so that the lever slides over the pin. The pin (48,50,52) between the two levers is attached to an operating arm (54) to which the corresponding pins of the other blades are also attached. This operating arm is moved by the damper actuating motor. The mechanism gives a large angle of rotation of the blades and provides a large closing force which presses the bades tightly against the fixed sealing strips (22,24,26) to give tight shut off.

Title: Fault current protective switch - keeps flux in transformer core constant by current in coil, used as criterion for disconnection
Inventor: GATH NIKOLAUS
IPC: H02H3/33
Filed: 1976-09-21
Abstract: A fault current protective switch is so used. It is so designed that the induction flux which is normally induced by the fault current in the core of a sum current transformer is maintained either at zero, or at different but constant value. The flux which is required for this purpose is generated by a current flowing through a transformer coil. Disconnection for protection of personnel from electric shock depends directly or indirectly on the current, or a value derived from it.

Title: Screw conveyor for removing forged bolt blanks - has hood enclosure with exhaust vent to remove fumes from press operation
IPC: B21J13/08
Filed: 1976-12-10
Abstract: The press which forges the heads of bolts or screws delivers the forged blanks by a chute. The blanks fall onto the chute of the screw conveyor (10). The screw conveyor is enclosed in a cylindrical hood (22) and is rotated by a belt drive from an electric motor (14). A duct (24) in the side of the hood is connected to a fan which sucks out any fumes emitted by the heated oil which covers the blanks. Any liquid oil drips through holes in the upper chute onto the lower chute and runs into the collector tank (13). By extracting the oil fumes from inside the hood any risk to the health of the operator is reduced.

Title: Extended capacity cartridge magazine - uses two sets of tension springs arranged on both sides of cartridge stack
Inventor: BEYER GUSTAV
IPC: F41A9/70
Filed: 1976-12-15
Abstract: A cartridge magazine for hanad weapons holds an increased number of stacked cartridges by utilizing space normally occupied by a spring at the bottom of the clip. The cartridges are stacked between double walls with a space in which tension springs are fitted. To obtain springs with a constant characteristic over a long path, the springs are arranged in two legs with free ends hooked on pins and the two legs doubled back over similar pins fitted inside the space. The pins are connected to the cartridge carrier lug on which the lowermost cartridge rests when the magazine is charged. The springs on both sides of the magazine exert a constant pull on the lug forcing the stack of cartridges towards the chamber.

Title: Drawer guide with axle-mounted rollers - has different axle diameters. for two rollers mounted in series for smooth running of drawer
Inventor: GRASS ALFRED ING
IPC: A47B88/14
Filed: 1977-01-19
Abstract: The drawer guide includes axle-mounted rollers (8) where one end of the axle (7) supports the roller which runs in a guide groove in the drawer whilst the other end transfers the load to the shell (1) via a guide slot and at least two rollers are provided one behind the other and have different axle dias.
