Patent EP-0048629-A2 (EP)
Inventor: EDGERLEY CHRISTOPHER JOHN
IPC: H05B6/20
Filed: 1981-09-23
Abstract: A channel induction furnace, particularly for melting aluminium has a pair of U-shaped channels (11, 12) extending downwardly from the bath (10). The channels have a radial width, measured outwardly from the axis of the core (13), which is several times the penetration depth in the molten metal for a current of the energising frequency and the channel section is tapered so that the channel is wider near the core and narrower away from the core. The planes containing the axes of the channels are skewed about an axis of skewing normal to the axis of the core. The large radial width gives a non-uniform current distribution resulting in flow patterns across the channel. The tapering provides an unbalanced electromagnetic pressure between the base of the loop and the bath and generates a further flow pattern whilst the skewing produces unidirectional flow through the channel. The combined effect enables high power to be put into the inductor without causing any pinch effect resulting in breaking of the metal path along the channel.

Abstract: Disclosed is a fixed data reading system which comprises a read only memory (2) for storing program data and fixed data, a random access memory (4) for storing non-program data, a program counter for specifying a location of the read only memory (2), an incrementer for incrementing the contents of the program counter (8), and a program counter input register (24) for supplying the incremented program counter contents to the program counter at a predetermined timing. The random access memory (4) includes a data counter area for storing an address specifying a location of the read only memory (2) in which the fixed data is stored. When the instruction for reading fixed data in the read only memory (2) is decoded, an address is supplied from the data counter area allocated in the random access memory (4) to the program counter (8). When executing an ordinary instruction, the corresponding address is supplied from the program counter input register (24) to the program counter (8).

Abstract: An incremental path measuring instrument is disclosed which includes a plurality of reference marks R1 . . . Rn which are interposed between respective code marks C1 . . . Cn. The reference marks and code marks are applied alternately and serially to the reference track included on the measuring scale. A scanning unit is included in the measuring device for scanning in series the reference marks and the code marks. Each of the code marks is unique, and only one of the two adjacent code marks and the respective reference mark must be scanned by the scanning unit in order to identify the reference mark unambiguously. When absolute position values are allocated to respective individual reference marks, the incremental path measuring device can operate in a quasi-absolute mode of operation, since then the position of each of the reference marks is established with respect to a predetermined zero point. Preferably, the code marks each contain beginning of block and end of block symbols in addition to the identifying information needed to identify the respective reference marks. The disclosed path measuring device includes an evaluation circuit which includes a circuit which automatically adapts the trigger threshold required for signal evaluation to the actual amplitudes of the signals.

Abstract: The improved dwell and depth attachment includes an elongate housing that is attached to a drill motor and has an output shaft that is movable longitudinally and rotatably in the housing for rotating a drill bit. A drive spindle is connected with the output shaft and extends through the housing. An elongated sleeve encircles the spindle and has an end that is engageable with the work piece. An adjustable depth control located within the housing is connected for movement with the spindle. A first portion of the control includes a threaded interior and has ten circumferentially spaced, radially extending holes therein. The control also includes a second portion that has a threaded exterior mating with the first portion and has ten slots equally spaced about the exterior. The threads are selected to be loose fitting so that the portions of the control can "float" relative to each other. A stop screw or the like is removably located in one of the radial extending holes in engagement with a radial surface on the second portion. The holes and slots are arranged so that rotation of the second portion relative to the first portion by one slot changes the drilling depth by one-tenth of the screw amount caused by full rotation. Further, movement of the stop screw from one hole to the next changes the drilling depth by one-hundredth of the amount caused by one full rotation.
