Title: A Method and Apparatus for Unbalance Correction
IPC: G01M1/30
Filed: 1980-04-23
Abstract: Material is removed from or added to a rotary workpiece to be balanced by a tool of which movement is controlled in dependence not only on the measured imbalance but also on the surface shape of the workpiece so as to blend the altered surface with the original surface. The tool is, therefore, jointly controlled by the imbalance to be reduced and parameters governing the area of the workpiece that can be engaged by the tool and the maximum penetration of the tool thereby. These parameters may be mechanically established by scanning, by means of a pin (4), a contoured body (1) corresponding to the workpiece being balanced or they may be electrically established. The body (1) is axially and angularly adjustable on a shaft (2) and is rotatable in synchronism with the workpiece. The tool (not shown) is controlled from the pin (4) by linkage (18, 19) and therefore its operation is governed by the angular and axial settings of the body (1) and the nature of the machining operation is dictated by the contour of the body (1). A template (15) may be provided to govern the manner in which machining is effected axially of the workpiece. <IMAGE>

Title: Direct Current Power Supply for an Electric Discharge Lamp
IPC: H05B41/00
Filed: 1980-06-05
Abstract: A circuit for supplying controlled DC power to an electric discharge vapor lamp during ignition, warm-up and normal operation has a bridge rectifier (30) and capacitor voltage doubler to convert AC line voltage into DC voltage of adequate magnitude to operate the lamp. The lamp (35) is connected in series with a semiconductor control circuit (100) across the DC supply. The control circuit operates as a resistive ballast whose effective resistance decreases as vapor pressure within the lamp increases during warm-up, thereby limiting lamp current to a safe value immediately after ignition while reducing the amount of power dissipated in the ballast circuit during normal operation for improved efficiency. The conductivity of the ballast circuit is controlled in response to variations in both lamp voltage and lamp current. In a further embodiment, Fig. 8 (not shown), controlled rectifiers in the bridge maintain a constant voltage drop across the ballast circuit and a self- oscillating source of firing pulses is employed to start the lamp. <IMAGE>

Title: Mercury holder for discharge lamps
IPC: H01J61/28
Filed: 1981-07-24
Abstract: A mercury holder 20 for electric discharge lamps, such as tubular fluorescent lamps 10, is mounted within the lamp envelope 11 so as to serve as a target for bombardment by electrons and ions originating within the envelope, eg. mounted on a lead-in wire 17 or on an anodic shield adjacent the cathode 13, whereby the mercury holder is heated until it bursts thus dosing the lamp with a required amount of mercury. The source of the bombardment may be the electrons emitted by one of the cathodes 13 which impinge on the holder 20 and which generate ions by collision with the gas fill in the lamp envelope 11. Alternatively, the source of the bombardment may be an arc discharge induced by a radio-frequency source across a gap between the holder 10 and a lead-in conductor 17. External focusing means 28 and beam-deflecting means 29 utilizing electromagnetic and/or electrostatic fields aid in targeting the particles at the holder 20.   <IMAGE>
