Abstract: ANTENNA BEAM BOUNDARY DETECTOR FOR PRELIMINARY HANDOFF DETERMINATION          ABSTRACT OF THE DISCLOSURE         An antenna beam boundary detector for a sectorized cellular system is disclosed. The difference in signal level received by a main directional antenna and a broad beamwidth antenna is determined  by detecting a modulator signal locally impressed on the signal received by the broad beamwith antenna. The signal level difference factor is the directional  antenna beam boundary when the two antennas are correlated. Interferometer effects are cancelled by detecting both amplitude and phase modulation of the locally impressed modulation.

Abstract: Rail Vehicle for Transporting Road Semi-Trailers Abstract A rail vehicle has a body with a hollow centre section that accommodates the suspension and landing legs of a road semi-trailer thus enabling the combined vehicles to be transported on a rail system with a restrictive loading gauge.  The rail vehicle utilises a two axle suspension arranged around the road vehicle components to provide a rail vehicle of the shortest possible length.  Part of the centre section of the rail vehicle can be swung outward on a sliding bearing thus enabling a road trailer to be loaded or unloaded from the side by means of a conventional road tractor unit and obviating the need for expensive terminal equipment. the wagon frame joining the parts of the wagon carrying the rail suspension is prestressed to ensure that vertical bearing surfaces of the sliding bearing are maintained in contact thus improving the integrity of the wagon and ensuring operation.

Title: Flow selector device
Inventor: DAHLIN DALE D
IPC: B05B1/30
Filed: 1989-07-31
Granted: 1993-03-23
Abstract: Abstract A flow selector device makes use of an annular plate having a plurality of flow control orifices spaced about its perimeter. The plate is rotatably received within a housing that includes a first fluid conduit formed therein. The plate is selectively rotated to bring any one of the orifices therein into alignment with an open end of the first conduit by means of a removable cover on the housing. The conduit includes an annular seal bout its open end and against which the orifice plate is pressed to seal the selected orifice within a fluid flow passage. A second fluid conduit is also provided and is connected to a clamp device mounting an open end of the conduit and a second annular seal. A clamp device is manually operable to securely clamp the plate between the seals, securing the plate in position with the selected orifice in line with and connecting the fluid flow conduits. The clamp device is also operable to release clamping pressure and thereby allow selective rotation of the orifice plate to bring a selected orifice into alignment with the conduit openings. The plate includes two sets of orifices arranged so that the plate may be inverted to bring either of the sets of orifices into operative positions where they may be selectively rotated into alignment with the conduit openings.

Abstract: SPREAD SPECTRUM POWER LINE COMMUNICATION                  ABSTRACT OF THE DISCLOSURE          This invention is directed to various improvements in spread spectrum power line communications.  One aspect of the invention relates to collision avoidance between various "slave" unit transmitters trying to send messages to a single "master" unit receiver by detecting whether the transmission path is in use and refraining from transmitting if it is.  Other aspects of the invention relate to controlling the frequencies of spread spectrum data messages transmitted, the use of Gold'scodes and switching frequency bands on the power line to avoid frequencies where there has been a deterioration of transmission.

Abstract: (Dimethylaminoalkyl)carboxylic and -carbamic acid esters and (dimethylaminoalkyl) ethers and ureas are compounds which are especially suitable for use as amine curing agents for polyepoxide compounds. They impart longer curing times to the curable mixtures and thus good processing properties, especially when the mixtures are used as adhesives. In addition, the mechanical properties are often improved. Further, these compounds afford advantages when used as curing agents on account of their low volatility.

Abstract: The invention relates to an electrode intended, for example, for electrocardiogram examinations, and capable of being held in position by suction. Vacuum conditions are created through a hose or tube (8), through which a measuring conductor (7) is drawn. The electrode comprises an inflexible backpiece (3), an intermediate component (2) made of an elastomeric material, and an electrode plate (1), preferably made of a silver-coated plastics. The intermediate component (2) includes a relatively inflexible sealing ring (9) which, in the operative state of the electrode, supports against the skin of a patient via a sealing lip (13) and against the opposing side of the backpiece (3). The electrode plate (1) is firmly connected to the backpiece, while the sealing ring carried by the intermediate component (2) is movable and can be readily sprung away from the backpiece (via resilient means 17). When no load is exerted on the lip-side of the ring and the ring is thus urged outwardly, a vacuum valve is closed automatically through the intermediate component (2), and is re-opened when the electrode is pressed against the surface of the skin, whereupon the electrode is held firmly by suction.

Abstract: In order to achieve the spectrum economy and reduce the power consumption of a transmitter and reduce the error rate at a receiver and simplify receiver circuitry, at least one bit stream to be transmitted is quadrature modulated in a manner that the signal points do not define a trace on a complex amplitude plane which passes through the origin of the plane coordinates or in the vicinity thereof. The received signal is hard limited and frequency-discriminated to determine the instantaneous angular velocity of the received signal and is integrated to detect the phase variation between two consecutive received signals, and thereafter is decided with respect to the phase variation according to the decision threshold levels 0 and +/- pi  radians.

Abstract: On a web offset or web letterpress printing machine, to ensure ganging of the paper webs (P1 - P4) to be folded and cut into newspapers (16), the positions of the main and subsidiary registers (5, 7) are controlled by positioning motors (Ml - M4) in dependence on positioning signals (SM1 - SM4). Over each funnel inlet guide roll (10), four photo-cells (11) are arranged beside each other with uniform spacing and detect brightness signals (HAl - HD4) at a sampling frequency of 20 kHz from the printed surface of the paper webs. These brightness signals are subjected to Fourier analysis in a microprocessor. The fundamental vibration is evaluated, the vibration of greatest amplitude being selected from the four fundamental vibrations of each paper web. The phase position signal associated with the selected fundamental vibration is used to calculate one of the positioning signals (SM1 - SM4). In this way, the cutting position of the paper webs (P1 - P4) can be determined without registration marks being applied to them.
