Title: Transversely radiating coil aerial - has extra conductor starting at coil beginning and extending at opposite direction to coil
Inventor: STEFFEN FRIEDRICH DIPL ING
IPC: H01Q11/08
Filed: 1991-06-26
Abstract: The coil aerial has a coaxial feed line (3), whose inner conductor (5) leads to a feed point at the start (7) of one turn (4). The outer conductor is electrically coupled to a metal support mast (1). An extra conductor (6) starts at the beginning of the coil turn and extends in opposite direction to the latter. The extra conductor is so long that an approx. circular radiation diagram in a plane is obtained, with the plane extending orthogonally to the coil axis through the aerial. Pref. two oppositely wound, coaxial coils (4, 4') with a common feed point are used. The coils may be symmetrical to a plane orthogonal to the coil axis. ADVANTAGE - Low material expenditure for required circular radiation diagram.
Patent DE-4128456-A1 (DE)
Inventor: RODRIQUEZ ANDRES MIQUEL
IPC: A47J43/044
Filed: 1991-08-28
Abstract: The invention relates to a comminuting device (2) for comminuting foods. The comminuting device (2) has an operating tool (3) which is mounted rotatably in a container (1) on a bearing pin (37) and is formed by an output shaft (31) and a knife (35), in which the output shaft (31) can be coupled via a coupling device (17) to a drive motor of a kitchen appliance, in particular a hand mixer. Constructed in the operating tool (3) is a brake (33) which interacts with the bearing pin (37) and can be switched on or switched off upon axial displacement of the operating tool (3) relative to the bearing pin (37). Axial displacement of the operating tool (3) is initiated when the lid (5) is placed on or removed from the container (1), i.e. as soon as the lid (5) has been removed, the operating tool (3) is decelerated. As a result, continued running of the knife (54) after the container (1) has been opened is avoided, thus reducing the risk of accidents. <IMAGE>

Patent DE-4134704-A1 (DE)
Inventor: KEPPLER MANFRED
IPC: B44C1/175
Filed: 1991-10-21
Abstract: Patterns are applied on a foil by a printing or photocopying process and the thus obtained composition is transferred onto permanent substrates made of various materials. The use of thin, soluble or porous foils allows the modifications required for each application to be obtained. Foil base materials and solvents are provided whose combination increases the solubility of the foil above that of the applied inks or toner. The solubility gap between the foil and the toners/inks is further enlarged by the use of porous and particularly thin foils. This process allows all kinds of patterns to be transferred onto any sufficiently solid surface; the edge of the foil is barely perceptible and adherence is very strong. The disclosed process and foils are particularly useful for transferring patterns generated by colour or laser photocopiers and in at least one variation are environmentally and occupationally safe.

Title: Control of warp moisture in sizing machine - using controllers acting on heat supply rate and speed to keep conditions between optimum limits
Inventor: NAKADE KIYOSHI
IPC: F26B13/06
Filed: 1992-05-23
Abstract: The moisture content of a warp (2) in a sizing machine is controlled by the forward speed (V), which is always kept below an upper limiting value, by a speed controller (23).
