Patent EP-0523422-A1 (EP)
Inventor: SANFORD GARY GEORGE
IPC: H01Q21/06
Filed: 1992-06-26
Abstract: A directional scanning antenna includes a circular array of a plurality of antenna elements extending several wavelengths in diameter. The number of antenna elements are sufficient to form a plurality of directionally-oriented subsets of active antenna elements and associated subsets of parasitic antenna elements. An antenna feed system provides connections to each one of the plurality of antenna elements that include connections to electronically variable reactances and connections to a source or receiver of electromagnetic energy. The antenna feed system is controllable to provide connections between the subsets of active antenna elements providing wave propagation and reception in one or more directions and to provide connections between a plurality of the remainder of antenna elements in associated subsets of parasitic antenna elements to assist the directionality of the antennas.

Abstract: 2.1. A known device of this kind having a movement screw requires a considerable installation length in the direction of the axial movement of the member because the change in the free length of the movement screw is equal to the axial movement. 2.2. To reduce the requirement for installation length while simultaneously retaining detectability of axial movement of the member which has occurred, the invention proposes to arrange on the movement screw (7) a second threaded region (6) of opposite hand with which the member (4) to be moved is in engagement and to guide the latter in a manner fixed against relative rotation. 2.3. One area of application of the invention is in the release apparatus of a spring cylinder such as that which is customary in the field of vehicle brakes. <IMAGE>

Abstract: The device serves for sealing closing an aperture (TO) having a plane floor region (FB) on all sides. The aperture is limited by a surround (TE; LP, RP, OT) without threshold. A sheet-like covering (AT) is pushed onto or pulled off from the surfaces (KT; LP, OT, RP) of the surround (TE) rectilinearly and laterally by displacement means (FS, KR, T; QR1, QR2, LS; AK, S, M, MT). At the same time, the displacement means are arranged at an acute angle (W) relative to the surfaces (KT) of the surround. Furthermore, the covering, rotated through the acute angle (W), is mounted on the displacement means, in such a way that, when it has been pushed on or pulled off, it assumes an approximately parallel position relative to the surfaces (KT) of the surround (TE) and is thus easily pushed on or away obliquely from the side. Finally, lifting means (EM1, EM2), which set the covering down on the floor (FB) in front of the aperture, are provided. For this purpose, lower supporting rollers (QR1, QR2) move into entry troughs (EM1, EM2) in a manner preferably guided via a running rail (LS). <IMAGE>

Abstract: The present invention describes an air-floated apparatus for use as a lawn mower or vacuum cleaner. In one embodiment, the apparatus comprises a housing (12) having an outer shroud and an inner shroud, the outer shroud surrounding a predetermined portion of the inner shroud to define a pressure chamber between the inner and outer shrouds and a vacuum chamber within the inner shroud. A drive mechanism includes a motor (18) having a rotatable shaft (15). A single impeller (14) is supported in the pressure chamber and rotates on the shaft for exhausting air from the vacuum chamber to erect grass underlying the opening while simultaneously pressurizing air in the pressure chamber to float the apparatus above the grass. Airborne cut grass clippings are vacuumed into and through the impeller (14) for distribution into the soil for recycle and recut. According to the invention, an adjustment assembly is provided for adjusting a position of the housing relative to a center-line auxiliary wheel assembly. The air-floated wheeled apparatus may include an edger and a trimmer.

Abstract: The method and apparatus provides a parity bit for every m multiples of b bits, a group of b bits being the smallest number of bits that can be manipulated by the CPU. The parity bit is computed for the entire m x b bits during a write operation, even if only a subset of the m multiples of b bits is being stored. The write operation is implemented as a read-modify-write operation of the entire m x b bits, with parity error reporting suppressed for the read portion of the operation. However, the parity bit is set factoring in whether a parity error is detected during the read portion of the operation. The parity bit for the entire m x b bits is checked during a read operation, even if only a subset of the m multiples of b bits is needed. Any detected parity error is reported to the CPU. As a result, hardware cost is substantially reduced with minimal degradation to data integrity. Furthermore, the method and apparatus is completely transparent to the CPU and the operating system.

Abstract: The disclosure relates to high purity (95 - 99.5 percent) red, orange and yellow filters (10) which comprise a periodic stack of relatively low index of refraction dielectric material (L) such as SiO₂ or MgF₂ and absorbing relatively high index material such as silicon or Fe₂O₃. Together, the low and high index materials provide a high index ratio (typically 1.7 to 2.5). The filters (10) are fabricated according to designs such as (H/2 L H/2) n , typically using only 5 to 7 layers. Despite the very small layer count, these filters provide overall optical performance which is at least the equivalent of all-dielectric filters of 30 or more layers, with color purity that is unachievable by all-dielectric filters and simple low cost design. In addition, the filters have inherently low stress levels and absorb and reflect unwanted light such as blue light. As a conequence, the filters are ideally suited for coating on flexible substrates such as plastics and for coating on lamp envelopes to form red or yellow bulbs which are ideally suited, for example, for use as automobile tail light bulbs, side marker bulbs and turn signal bulbs.

Abstract: The flue gas flows through a reaction space (20, 20') in an axial direction (arrow A). In the direction of flow there are arranged one after the other a plurality of groups of nozzles (15 to 18; 15' to 18'), via which ammonia is introduced into the flue gas by means of a carrier medium. Each group has at least two nozzles essentially uniformly distributed over the periphery of the reaction space, which nozzles are provided in a shared plane extending transversely to the direction of flow of the flue gas. The nozzles are arranged in such a way that the carrier medium exiting from them generates a rotary flow about the flow axis of the flue gas, the rotary flow of the nozzles (15; 15') of one group being in the opposite direction to the rotary flow of the nozzles (16; 16') of the adjacent group. <IMAGE>

Date Oct. 15, 1992The invention relates to a method for determining the transmission characteristics (H(jf)) of an electric line (2) in an ISDN system, in which a test signal (m(t)) is applied to the line (2) at one end, and at the other end of the line (2) the received signal (g(t)) produced owing to the test signal (m(t)) is evaluated. In order to be able to carry out such a method using a test signal having a crest factor of one with relatively little cost, use is made as test signal of a binary, bipolar random number sequence signal (m(t)) having the crest factor of one, and during a time interval corresponding to the period of the test signal (m(t)) the received signal (g(t)) is scanned and subjected to a Fourier transformation to obtain a spectral signal (G(jf)); the latter is complexly multiplied by a reference spectrum Mi(jf) to obtain an output signal (H(jf) which represents a measure of the transmission characteristics of the line (31).
