Title: Improvements in or relating to the manufacture of high pressure mercury discharge lamps
IPC: H01J9/38
Filed: 1955-10-06
Abstract: 798,631. Discharge lamps. SYLVANIA ELECTRIC PRODUCTS, Inc. Oct. 6, 1955 [Oct. 6, 1954], No. 28546/55. Drawings to Specification. Class 39(1). A method of manufacturing a high pressure mercury discharge lamp to have a pre-determined operating voltage, the lamp comprising an envelope having an elongated exhaust tube extending therefrom and having within it electrodes and a quantity of mercury and argon at 8 mms. pressure, comprises passing a current between the electrodes to vaporize the mercury and heating the exhaust tube in the region near the envelope whilst allowing the remainder of the exhaust tube to remain-cool, the passage of the current and the heating of the exhaust tube being continued until the voltage between the electrodes has risen to a maximum and has begun to fall, discontinuing the passage of current and heating of the exhaust tube when the voltage has fallen to the desired value, allowing the lamp and exhaust tube to cool and subsequently sealing off the exhaust tube at a point such that the mercury condensed in the exhaust tube is sealed out of the lamp. Apparatus for carrying out the method includes means for supporting the lamp horizontally, an electromagnet for keeping the arc horizontal, an envelope enclosing the lamp to reduce heat losses, and means for projecting air on to the envelope in the cooling step. An electrical resistance heater can surround part of the exhaust tube during the passage of current. During the operations residual contaminants diffuse into that portion of the exhaust tube which is ultimately sealed-off. General lamps being dealt with can be positioned in cubicles in a container.

Abstract: 1513817 Recognizing shapes AGENCY OF INDUSTRIAL SCIENCE & TECHNOLOGY 7 July 1975 [8 July 1974] 28602/75 Heading G4R A shape having at least a plurality of straight sides is determined by projecting the shape on to a fixed plane, e.g. using a video camera, to provide a series of projection values. The values are differentiated to determine where the junctions between the sides occur so that the signal shown in Fig. 2c represents the slope of the outline of Fig. 2a. The differentiated valves are then further differentiated. The shape or the camera is rotated and the angle of rotation measured. The angle is noted when the second differentiation indicates that a side of the shape is parallel to the fixed plane. The different angles detected and the length of each side, determined when it is parallel to the plane, can be compared with a list to determine which shape has been detected, or can be displayed.
