Title: Noise reduction for three plate circulator - uses chamfered microwave ferrite discs in inner conductor region
Inventor: GOLOMBEK WERNER DIPL ING
IPC: H01P1/387
Filed: 1979-12-15
Abstract: The circulator, as used in microwave communications systems as a transmit-receive switch, of three plate junction type comprises outer conductors (4) of non-magnetic material which carry the permanent magnet inserts (3) and soft iron pole shoes (5) which connect with the microwave ferrite discs (7). The inner conductor (6) is sandwiched between the discs. Where the inner conductor crosses the edges of the discs these are chamfered. Typically the chamfer covers between a third and three-quarters of the disc thickness, and has an angle between 10 and 40 degrees to the disc plane. The arrangement results in an improvement in signal to noise ratio of from 9dB to 7dB. In circulators without pole shoes the chamfering faces the outer conductors.

Title: Large hangar type opening roof - has upper element sliding across lower element weighted towards closure
Inventor: HAESELBARTH WERNER
IPC: E04B7/16
Filed: 1979-12-19
Abstract: Root elements displaceable downward in the slope for opening, are incorporated in the roof, esp. for a hangar-type building with a spacious interior. On one side of the ridge, at least, an upper roof element (24) is movable over at least one lower movable one (20, 22).

Title: Pressure roller bending correction - has pressure pockets to eliminate friction contact
Inventor: SCHIEL CHRISTIAN
IPC: F16C32/06
Filed: 1980-03-26
Abstract: There is a central hydrostatic pressure pocket on the sliding surface of the pressure section facing the roller mantle, with a pressure zone between the flexible carrier and the pressure section, with a connection to a pressure source. There are at least four additional pockets grouped around the central pressure pocket on the sliding surface, with a rim round the whole pressure pocket zone. The central pocket is profiled to give extensions along the line of the pressure roller axis, as far as the rim, while the additional pockets lie diagonally to the pressure roller axis. Designed to correct the bending movement of a flexible pressure roller, for handling paper and other web materials, there is a better performance by eliminating any friction contact between the pressure section and the roller mantle.

Title: Safety switch for electrically operated equipment - incorporating switch handle in machine steering or guiding handle, with switch connected in motor circuit
Inventor: ROTTENKOLBER LUDWIG DIPL ING
IPC: F02B3/06
Filed: 1980-04-30
Abstract: The typical application of the safety device is to hand guided motor driven choppers or riddles. Attached to one of the guiding or operating handles (2) of the machine is a lever handle (16) with a spring return (8). This handle (16) engages with an electrical switch (10). Leads (11) from the switch go to an electrical interlock on the motor driving the machine. In order to operate the machine the lever handle must be depressed (18) towards the main handle (2). The normal action is to hold both handles at the same time in one hand. If an adjustment has to be made, or an obstruction cleared, then letting go of the main handle automatically trips the drive and the operation can be conducted in safety.

Title: Gas-fluid spray generation method - regulates proportions by varying passage cross=sections in mixer
Inventor: WILD WALTER DR MED
IPC: B05B7/12
Filed: 1980-06-30
Abstract: The method generates a gas/fluid spray from a nozzle and is esp. for oral hygiene. A gas is directed by a passage into a mixer with a vessel for the fluid, the latter being pressurised via a tapping from the passage and delivered back to the latter for mixing with the remaining gas. In the mixer (3), the proportion of gas to fluid (7) is regulated by altering the cross-sectional area of the passages (5,11,12) for gas and fluid passing through it. There can be a throttle (13) in the gas passage (5) causing gas back-pressure and thus increasing gas pressure on the fluid via the tapping (11) leading to the vessel (8) containing the latter.

Filed: 1980-08-01
Abstract: A bubble pack is formed from two sheets welded or heat sealed together, the bubbles forming medicament (25) accommodating chambers (8). The strength of the resulting package is such that a child can neither force a pill from its chamber (8) nor breach the chamber by tearing the package inwardly from its edge, manually. Along an edge of the package is a row of notches formed by intersecting edge portions (9, 10), each notch optionally having an inwardly-directed incision (11) at the root (12) thereof. The notches assist tearing of the package which will yield to a force an adult can muster but not musterable by a child. <IMAGE>
