Title: Improvements relating to electric discharge lamps
IPC: H01J17/00
Filed: 1944-05-20
Abstract: 586,685. Discharge lamps. SIEMENS ELECTRIC LAMPS & SUPPLIES, Ltd., and ALDINGTON, J. N. May 20, 1944, No. 9784. [Class 39 (i)] An electric discharge lamp adapted to be operated by passage of currents of high intensity and short duration comprises a quartz or hard glass envelope filled with gas at pressure at least 100 mm. of mercury and enclosing a pair of electrodes, the seals being designed for steady currents of at least five times the continuous operating current of a lamp having the same dimensions. The electrodes should also be substantially heavier than for continuous running. With momentary. current densities of 1000 amps per sq. cm. of tube cross-section unactivated electrodes of tungsten may be used, provided they reach a temperature of 1000‹ C. in the course of a flash. With current densities of the order of 300 amps per sq. cm., an activated electrode, such as described in Specification 565,689, is preferably employed. The spacing of the electrodes and the gas pressure should be such that the break-down voltage between the electrodes is not less than 2000 volts. The lamp is preferably tubular with spherical enlargements about the electrodes. In an example, the tube is of 8 mm. bore with electrode spacing 60 mm., and a filling of krypton at 200 mm. of mercury. The electrodes are of tungsten rod 4 mm. diameter and 10 mm. long and the seals are of molybdenum foil capable of carrying 50 amps on continuous load. The lamp is operated by a bank of condensers of 40 mf. capacity, charged to 4000 volts. The break-down voltage of the tube is somewhat above 4000 volts ; it may be caused to break down at a somewhat lower voltage by means of a high-frequency field. Neon, argon or a mixture of gases may. be employed instead of krypton. The tube may be provided with a surround coated with fluorescent powder, or may itself be so coated on the exterior. Specification 569,267. also is referred to.

Title: Power transfer circuit including a sympathetic resonator
Inventor: BOSSI BURT JOSEPH
IPC: B42D15/10
Filed: 1996-07-11
Abstract: A power transfer circuit includes first and second windings (L1,L2) sharing a common magnetic core (101). Each winding (L1,L2) has associated with it a parallel capacitor (C1,C2) to thus form a pair of "tank" circuits. The first winding (L1) is connected at one end to a voltage supply and, at the other end, to ground through an FET switch (100,200). The switch (100,200) is turned on and off at a predetermined frequency and at a 50% duty cycle. The second winding (L2) and associated capacitor (C2) achieves parallel resonance at the predetermined frequency. Similarly the combined first and second windings (L1,L2) and associated capacitors (C1,C2) achieve parallel resonance at said predetermined frequency. The second winding (L2) need not be electrically connected to the first winding (L1) which transfers energy to it through the magnetic core (101). The transfer circuit efficiently couples power across a dielectric interface to a pickup coil (L3). One particularly good application of the power taansfer circuit is in connection with a contactless Smart Card.

Title: Head for attaching and detaching cover and cover attaching and detaching device using the same
Inventor: KATONO HISAO
IPC: B67B3/20
Filed: 1996-01-08
Abstract: PROBLEM TO BE SOLVED: To provide a small turning torque, in a head for tightening a circular plate- shaped cover having small height, in the initial stage of cover tightening by means of contact pressure with the cover and provide a sufficiently large torque in the final stage of cover tightening. SOLUTION: In a head 10, one end 12a of a mounting shaft 12 is mounted to a chuck at the forward end of a drive axis of an electric motor, and a supporting seat 16 and a contact member 18 are provided on the other end 12b of the shaft 12 successively from the side of the shaft 12. The member 18 is made from natural rubber or silicone rubber and formed into a circular plate-shape. While the member 18 is being turned about the shaft 12, a contact surface 18a of the member 18 is brought into contact with the top surface of the circular plate-shaped cover. Since a surface contact is provided between the contact surface 18a and the top surface of the cover, turning torque given to the cover can be adjusted by corresponding to the contact pressure between the surface 18a and the top surface of the cover. As a result, by using a simple mechanism for lifting or lowering the head 10, problems can be solved and hence construction of device for attaching and detaching a cover using the head 10 can be simplified, resulting in reduced cost.
