Patent GB-2049325-A (GB)
Title: Tuning a trap circuit
IPC: H04N5/44
Filed: 1980-04-11
Abstract: A network for attenuating the adjacent channel sound carrier signal in a television receiver includes first (60) and second (70) trap circuits intermediate the R.F. mixer (30) and the first I.F. amplifier (100). The trap circuits are tuned to frequencies in the vicinity of and above and below respectively the nominal frequency of the adjacent channel sound carrier and are mutually coupled to produce a composite response curve exhibiting maximum attenuation in the vicinity of the nominal frequency location of the adjacent channel sound carrier. The trap circuits provide attenuation in excess of that required to eliminate adjacent channel sound carrier interference over a bandwidth sufficient to encompass expected carrier deviation due to frequency modulation, carrier mislocation, and trap mistuning. A method of tuning at least one of the trap circuits to the nominal frequency is provided by comparison in a process controller 20 which adjusts inductors of the network until the null frequency of the trap circuit is aligned with the nominal frequency so as to provide the required network characteristic. <IMAGE>

Patent GB-2102755-A (GB)
Title: Flettner rotors for ship propulsion
Inventor: WAGNER CLAUS
IPC: F03D3/00
Filed: 1982-06-07
Abstract: A wind drive for a ship comprises a Flettner-rotor 1 and an sail 3 which is symmetrical and rotatable about its pitch axis 4. In operation the Flettner-rotor 1 is rotated about its axis 2 and this gives rise to a high flow velocity and a low pressure region where the surface of the rotor is moving with the wind, and a low flow velocity and a high pressure region where the surface of the rotor is moving against the wind. The high and low pressure areas cooperate to generate a propulsive thrust. The sail, which can be a rigid sail 3 or a cloth sail is positioned so that it does not affect the flow processes at the rotor but still profits from the higher flow velocities. The sail thus also generates a propulsive thrust. <IMAGE>

Title: Valve rotating device for an internal-combustion-engine valve
Inventor: MAY ARNOLD
IPC: F01L1/32
Filed: 1982-12-15
Abstract: The device includes a circular array of rolling bodies (2) disposed in sloping pockets formed in a base member (3). An annular spring disc (1) normally presses the rolling bodies (2) fully down into their pockets. In use of the device, a valve spring so stresses the spring disc (1) during valve opening, as to result in the rolling bodies (2) being relieved of loading by the disc (1); under the urging of springs (8) housed in the pockets, these bodies (2) now move up to the shallower ends of the pockets. As the valve closes, the rolling bodies (2) are loaded again by the disc (1) and the resultant rolling of the bodies (2) down into their pockets causes the base member (3) to rotate relative to the spring disc (1). Further rolling elements (6) are interposed between the spring disc (1) and base member (3), intermediate the rolling bodies (2) and the zone of action (7) of the valve spring on the disc (1). <IMAGE>
