Title: Improvements in or relating to electrical induction furnaces
IPC: H05B6/24
Filed: 1929-01-08
Abstract: 324,789. Davis, N. R., and Associated Electrical Industries, Ltd. Jan. 8, 1929. Induction furnaces.-The lining or lagging of a coreless induction furnace is dried out by enclosing within said material a metallic body which is heated by eddy currents when the furnace coil is energized. The metal body is subsequently rendered sufficiently discontinuous to prevent circulation of eddy currents therein during the ordinary operation of the furnace. The metal body comprises a cage formed of strips 1 riveted at the top to a ring 2 and turned inwards at the bottom and riveted to a discontinuous annular plate 3. The parts 5 of the ring 2 between the strips 1 and the parts 9 of the bottom portions of the strips 1 are of reduced cross-section. The ends of the ring 2 are separated by insulation 7. The cage is inserted in the inductor and zircon sand or other lagging material is rammed into the space between them. Ganister is packed between the strips 1 to prevent the sand escaping. The inside of the cage is then lined with silica or magnesite with or without tar. A metal pot may be inserted in the cage and the lining rammed therearound. The cage melts at the restricted portions 5, 9 after the drying out is effected and a vent may be provided to allow the molten metal to escape. The metal pot also melts and is poured out with the melted charge. The remaining portions of the cage may be connected to earth to form a protective screen as described in Specification 323,561. The cage is made of non-magnetic steel or cast iron. A formula is given for the width of the strips.

Abstract: 696,417. Copy milling. ROLLS-ROYCE, Ltd. Jan. 1, 1951 [Jan. 11, 1950], No. 780/50. Class 83 (iii). [Also in Group XXIII] In a copy-milling or copy-grinding machine, for turbine or compressor blades 29 with inclined surfaces 29c on either or both the root or tip platforms 29a, the blade and the tool 32 are traversed relative to each other by causing angular movement of the blade or tool about an axis 20 which is contained in the plane of the tool and does not pass through the blade. If the platforms have inclined surfaces at one end only, the axis 20 lies in the plane of the inclined surface, but if both platforms have inclined surfaces, it lies on the intersection of the planes of these surfaces, so that the whole of the blade profile, including the parts near the inclined surfaces, can be machined at one setting. A slide 12 is vertically movable in the machine frame 10 and carries another slide 13 which is horizontally reciprocable by an electric motor 18 and crank drive 19. The work-carrier or carriers 11 and the carrier 22 for the pattern 30 are oscillated on vertical pivots 20, 23 on the slide 13 by a motor 26, crank 25 and link 21. A follower 31 is mounted for limited vertical movement in the frame so that it controls vertical movement of the slide 12 in the opposite direction by an electric motor 15 and skew drive 16 or by hydraulic or mechanical means. The angular traverse, indicated by arrows 35 in Fig. 3, may be rapid and the linear traverse (arrows 36), slow so that the cuts are substantially circular arcs, or the angular traverse may be slow and the linear traverse rapid, so that the cuts are substantially along radial lines from the axis 20. The linear traverse and the copying movement may be applied to the tools instead of to the blades and an equivalent to the linear traverse may be obtained by rotating the blades and the pattern about corresponding axes remote from and parallel to their spanwise axes.

Title: Optical communication device
Inventor: KURIBAYASHI AKIRA
IPC: H04W52/10
Filed: 1998-01-06
Abstract: PROBLEM TO BE SOLVED: To change the current flowing in a light-emitting element of a transmitting side of an optical communication device, corresponding to the distance between optical communication devices and to reduce the current consumption of a transmitting device by providing a constitution such that a control means outputs a control signal to a current control means, based on the signal outputted from an amplifying means and the current control means controls the current flowing in a light-emitting means based on the control signal. SOLUTION: The current flowing in an infrared-ray emitting element 6 is controlled at execution of communication. In other words, the control signal that is supplied to a current control circuit 8 for controlling the current flowing into the element 6 is outputted from a control part 1, based on the output of an cooperator circuit 4 or an A/D converter circuit 5. Although the current flowing into the element 6 is controlled based on the state of the control signal, since the intensity of the infrared rays is determined by the current flowing into the element 6, it is possible to vary the infrared-ray intensity through the control of the current flowing into the element 6.
