Patent EP-0072595-A2 (EP)
Inventor: WORSTER FREDERICK ERNEST
IPC: H04N3/233
Filed: 1982-08-11
Abstract: With television displays and especially with such displays for colour projection television it is quite possible to obtain a display raster which exhibits distortions on its vertical sides, namely tilt and bow distortions. These may be corrected by the present line deflection arrangement which comprises a line output switching transistor (TR1), a load inductor (L1), an '8' correction capacitor (C1) and the line deflection coil (Ly). The series arrangement of a current limiting inductor (L2) and diodes (D1 and D2) poled in opposite directions is connected in parallel with the deflection coil (Ly). A resistor (R1) and a transistor (TR2) are each connected in parallel with diode (D1) whilst a variable resistor (R2) is connected in parallel with diode (D2). A resistor (R3) shunts the base-emitter junction of transistor (TR2) whilst input terminals (10 and 11) are respectively connected to the base and collector of that transistor. In the absence of a signal at terminals (10 and 11) the circuitry shunting the deflection coils (Ly) acts as a centring circuit with a static offset current being produced through the deflection coils (Ly) which produces a static magnetic bias in the direction of line deflection. Transistor (TR2) operates in class A and is biased to its mid-conduction point so that it effectively provides a given impedance in parallel with resistor R1. To correct the geometric distortion the terminals receive a field frequency signal input which modulates the conduction of transistor (TR2) and hence its impedance at field frequency. To correct for tilt distortion this signal is a field frequency sawtooth whilst to correct for bow distortion this signal is a field frequency parabola, a combination of these signals being used to correct for a combination of these distortions. This modulation produces a modulated magnetic bias through the deflection coils (Ly).

Abstract: A loudspeaker is provided for high-quality and particularly stereophonic sound reproducing systems positioned close to a wall of a room. To reduce distortion due to that part of the reflected sound which arrives from substantially the same direction as the direct sound, the positioning of the sound radiating surfaces is such as to make the reflected sound from the wall arrive substantially in phase with the direct sound throughout a large frequency range, whilst at higher frequencies the reflected sound is attenuated by a sound absorber.The loudspeaker has a casing with a rear wall (5a). Loudspeaker units arranged to be the sound source for mid-range (12b) and/or high (14a) frequencies has the sound radiating surfaces (12b, 15a) at short distance (D2, D1) from the plane of the rear wall (5a) and facing slantwise forwards. A sound absorber (28a) at the side of the casing, in front of and near the plane of the rear wall (5a) and near the sound radiating surfaces (12b, 15a), serves to attenuate that part of the sound reflected by the room-wall which has wave-lengths shorter than eight times the shortest distance (D1, D2) of the sound radiating surfaces from the plane of the rear wall (5a).In stereophonic systems the left-hand and the right-hand loudspeakers form a mirror-image pair.

Abstract: A method for preventing interference between relatively moveable components of a computer controlled industrial machine in which the position of the moveable machine elements are controlled by a computer program. For each movement, the computer first determines a predicted path for the movement and thereafter determines whether the path will intersect a safe zone, a safe zone being defined as a zone containing an element which is to be protected from contact with the moveable element. If a predicted path intersects a safe zone, the machine operation is halted. Provision is made for manual moves, i.e., movements not directed by the computer up to the nearest intersection point with a safe zone.

Abstract: The present invention is directed to a method and apparatus for centrifugally separating substances of different atomic weights. The substances to be separated are positioned in an evacuated vessel (1) which has a longitudinal axis. A magnetic field is generated in the vessel (1) parallel to the longitudinal axis of the vessel and a target (7) consisting of the substances to be separated is positioned within the vessel at one end thereof. A collector (17) is positioned at the other end of the vessel. Pulsed laser energy is focused on the substances to be separated, thereby fully ionizing at least a portion of the substances and forming a plasma therefrom. Immediately following the focusing of the laser energy, a current is passed through the substances to be separated which causes further full ionization of the substances and thereby the formation of additional plasma. The ionized plasma is rotated and moved from the substances which are to be separated to a collector by the application of the magnetic field. At least a portion of the ionized substances are separated by the centrifugal force resulting from the rotation of the plasma by the magnetic field. At least one skimmer means (13) is positioned in the vessel in the path of a portion of the ionized plasma such that the portion of the ionized plasma strikes the skimmer means and is collected thereon. The remainder of the ionized plasma continues movina alona the vessel towards the collector.

Abstract: The gauge consists of two main electrodes, viz. a measuring electrode (M) and a compensation electrode (R) acting as reference-electrode, cooperating each with an earthed counter-electrode, so that two plate-capacitors with capacities C M  and C R  or two measuring cells with conductivities ε M  and  ER  can be formed. 
     An electronic circuitry determines the quotient of the capacities and conductivities respectively, said quotient being a measure for the liquid level and the liquid conductance respectively. In a first event the electrode surface area functions as variable, since the measuring electrode is formed as a rightangled triangle and the compensation electrode as a straight strip. In the second event the surface areas of measuring and compensation electrodes are kept equal, but functions the distance between measuring-electrode and counter-electrode as variable, in which the distance between main electrode and counter-electrode increases linearly, whereas that between compensation electrode and counter-electrode is kept constant.

Abstract: The disclosed frozen confection machine is provided with a series of mold bars each of which contains a plurality of cavities for containing confection material which is frozen in said cavities. The machine is provided with a mechanism for inserting sticks into the partially frozen confection material, means for defrosting the exterior of the cavities to facilitate removal of the frozen confections and a selectively operable device responsive to the inadvertent retention of confection material in one or more cavities to remove the retained confection material by inverting the mold bar and spraying hot water into the cavities to remove the confection material. Moreover the confection machine provides laterally opposed to chains circulating in a closed path in which one reach of the chain, the working reach, associated with filling, freezing, stick insertion and confection removal devices and a return reach. The working reach of the chains are collapsed crowding the series of mold bars in substantially abutting relationship to thereby provide a solid wall of mold bars. This arrangement substantially reduces the number of mold bars required for producing a given number of confections per unit time, substantially reduces contamination of its cavities with brine and substantially reduces the amount of water used since washing of the mold cavity is selective.
