Title: Infrared irradiation device for medical purposes
IPC: H01K7/00
Filed: 1976-10-25
Abstract: Arranged in sandwich configuration in the upper part of a device housing (1) is a support layer (4) of a good heat-radiating material. Situated on the inner side of the support layer is an electrically conducting heating film with pad electrodes (9), to which an electricity lead (10) is connected. The heating film is formed by applying a plastic dispersion with added carbon black onto the support layer. The space between the heating film and the closed upper part of the device housing is filled with an electrically insulating and heat-insulating layer (6) of rigid polyurethane foam. The lower part (1b) of the device housing projects beyond the support layer, so that there is a safety distance between the area to be treated and the support plate radiating the heat. The edge of the lower part of the device housing is provided with a padding (2). This radiation device permits a uniform surface radiation of the areas to be treated. <IMAGE>

A heat shield comprising ceramic members 119, 118, 117 extends over the tube 10 and member 37, the inner part of which is shielded by a ceramic plug 84 spring-loaded against member 76. The slanting sides of the face member 90 may also be thermally insulated by ceramic coatings (171), (172), Fig. 4 (not shown). The plug may be replaced by a water-cooled ceramic coated metal cap member (151), Figs. 3, 5 (not shown), electrically insulated from member (90). In another embodiment, Fig. 6 (not shown), the tube (10) is replaced by coaxial water-cooled sleeves (224), (235), the ceramic heat shield (232) is reinforced by wires (233), and the coil comprises eight turns separated by insulation (283) and disposed in P.T.F.E. resin. Each turn contains a fluid passageway (282) and fluid flows to and from the coil in hollow leads (207), (208). The electrode may be used with 3-phase A.C. or D.C.; the coil is supplied with D.C. The electrode may be used in direct, indirect and submerged arc furnaces, e.g. for melting of para- or ferromagnetic materials.

Abstract: 1,115,658. Control of A.C. motors. INTERNATIONAL STANDARD ELECTRIC CORPORATION. 5 Nov., 1965 [5 Nov., 1964], No. 46974/65. Heading H2J. [Also in Division G3] A squirrel-cage induction motor 1 has a fourpole A.C. stator winding supplied through silicon-controlled rectifiers 2a-2c shunted by diodes 3a-3c, the triggering of the controlled rectifiers being phase-regulated in accordance with the deviation of the motor speed from a set value. A sixteen-pole stator winding is supplied with D.C. from transformer through controlled rectifiers 5a, 5b and diodes 6a, 6b, for braking. Trigger pulses are supplied to the rectifiers 5a, 56, from control unit 8, which, like the control unit 4, compares a reference voltage with the output of tachometer generator 9. If the speed of the motor is excessive, controlled rectifiers 2a-2c are blocked whilst the rectifiers 5a, 5b are triggered for braking. The motor may drive a lift, a deceleration programme being nitiated by closure of a contact in the lift shaft whereby a voltage varying with time is added to the tachometer voltage. This provides a steady reduction of speed. In another arrangement, the starting operation of the lift is time-controlled in a similar manner, the change-over between the acceleration and retardation programmes being effected smoothly by a diode selector circuit. The rotor is provided with high-resistance rods which are insulated to prevent transverse current between adjacent rods. This allows the motor to have a smooth, non-peaking, speed-torque characteristic for the braking operation.
