Title: Improvements in or relating to the supply of electric power by means of discharge apparatus
IPC: H05G1/40
Filed: 1947-07-18
Abstract: 640,026. Controlling current by discharge apparatus. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. July 18, 1947, No. 19307. Convention date, April 1, 1941. [Class 38 (iv)] [Also in Group XX] To ensure ignition early in the anode voltage cycle of ignitrons 17, 18 interconnecting an A.C. source 15, 16 and a high power factor load, such_ as the high voltage transformer 12 for an X-ray tube 10, and thereby to reduce Bucky grid shadows on an X-ray plate and to permit a more accurate interpretation of dosemeter indications, the normal voltage in the ignition circuit (i.e. the voltage across the anode-cathode space) is boosted by a transformer 34, the primary winding of which is excited by the anode-cathode voltage. Energization of the load for a predetermined and adjustable period may be controlled by a timer 35 comprising camoperated switches 45, 46, 57 actuated by a motor 36 and which interrupt the ignition circuit of the ignitrons when the predetermined period expires. Upon closure of the initiating switch 63 relay 65 is energized over contact 64 and completes the circuit from source 15, 16 to an autotransformer 66 for feeding the high voltage transformer. Contact 71, associated with the initiating switch, subsequently closes and energizes magnet 59 to clutch the cam-shaft 38 to the motor 36 ; cam 39 immediately closes contact 45 and the ignitrons conduct due to completion of their ignition circuit at contact 45. Contacts 46, which are in series with contact 45, are normally closed, but are opened in succession as the cam-shaft rotates. Upon opening of one contact 46, selected by a tapping arrangement 47-53, 55, the ignition circuit is interrupted and the load current terminated. Further rotation of the cam-shaft closes contact 57, thereby energizing relay 58 which then holds in and interrupts the supply to the clutch magnet 59. To provide for balanced operation of the ignitrons variable resistors 261, 271, allow adjustment of heating current applied to each igniter 21 by a transformer 25. In a modified arrangement the ignitrons are disposed in the connection between the autotransformer 66 and the primary winding 13 of the high-voltage transformer, a second boosting transformer injecting into the ignition circuit a voltage which compensates for the variations in the main voltage boost consequent upon change of the tapping point 67. A resistor may shunt the winding 13.

Title: Method of manufacturing pin fin surface
IPC: B21D53/02
Filed: 1949-07-22
Abstract: 666,025. Making heat-exchangers. AIR PREHEATER CORPORATION. July 22, 1949 [July 23, 1948], No. 19318/40. Class 83 (ii). [Also in Group XIII] A method of forming a finned heat-transfe r element for a heat-exchanger comprises forming in a plate 10, a number of spaced perforations 11 disposed in parallel rows 12, bending the plate along lines A-A for raising from the plate surface the halves 15, 16 of the strips 13 which. are then pressed together and welded or brazed to form unitary fins. The plate 10 (Fig. 1), is also bent in an upward direction along lines B-B and C-C. By narrowing the width of the strips 13 the fins 20 become pinlike. The finned elements may be stacked upon each other (with or without brazing) and inserted in the fluid passages of a regenerative heat exchanger or brazed to intervening plates 21 having channel fins 22 (Fig. 3). In another embodiment the plate 30 (Fig. 4), has perforations 31 and is creased on the lines F-F. Thus the bend line is at the base of the ligaments 34, 35 and the plate is bent upwardly' along lines G-G and H-H so that the entire ligaments 34 and 35 are brought into contact to form fins 40 (Fig. 5). For use in a heat exchanger of annular cross-section the bend lines G-G, H-H are slanted and the width of the perforations gradually increased so that the fins will be progressively longer along the core radius and one side of the finned strip will be tapered to accommodate the radial flow passages of the annular core. The rows of perforations in the plate may be offset to stagger the pin-fins.

Title: Method of manufacturing micro-circuit structures
IPC: H01L21/288
Filed: 1970-04-24
Abstract: 1311684 Semi-conductor devices KOGYO GIJUTSUIN 24 April 1970 [15 Oct 1969] 19791/70 Heading H1K A small diffusion width is determined by forming a substance layer on a semi-conductor substrate and changing the composition of the substance surface layer, e.g. by oxidation, to a desired depth, forming a hole in the changed surface layer, dissolving out the unchanged substance via the hole, and diffusing an impurity into the substrate on both sides of the surface layer, using the surface layer, where it abuts the substrate, as a diffusion mask. In an embodiment aluminium is used to form a substance layer 200A and oxidized to form layer 201A. The aluminium is dissolved in NaOH solution, and an impurity of the opposite type to the substrate diffused into the substrate, from the gas phase, to form regions 101A and 103A, separated by a width which is determined by the thickness of the oxide layer 201A and the diffusion conditions. The device may be a field effect or bilateral transistor. In a second embodiment, following the formation of the oxide layer, a silicon oxide or nitride coating containing an impurity of the opposite type to the substrate is deposited on the aluminium oxide layer. A hole is formed through the layers and the aluminium removed by dissolution. Subsequently heat is applied to form diffused regions (102A), Fig. 3 (not shown), in the substrate. A second diffusion, of an impurity of the same type as the substrate, takes place, a region (101A) being formed in the substrate below the surface originally occupied by the aluminium layer and forming a heavily doped region (101A), and second regions (103A) are formed in the first regions (102A). The invention may also be used to mask metal plates, e.g. of platinum.

IPC: B65H63/06
Filed: 1956-06-28
Abstract: 861,225. Photo-electric gauging. LASTEX YARN & LACTRON THREAD Ltd. June 26, 1957 [June 28, 1956], No. 19998/56. Class 40 (3). The variations in diameter of a thread or other filamentary material 22 moving over an aperture 24 in a screen 23 are detected by a phototransistor unit 26 which receives light via the aperture from a source 25. The A.C. component of the phototransistor output signal, which has an amplitude which varies with the variations in thread diameter, is applied with a superimposed 3 kc/s. signal from the oscillation 28 to an amplifier 32 which is biased to limit signals exceeding predetermined positive and negative valves (waveform 33). The amplifier output is applied to a H.P. filter 34 which removes the original photo-transistor signal whereby its output consists of a 3 kc/s. signal which drops to zero when a variation in thread diameter produces a signal exceeding the value which produces a limiting action in the amplifier 32. This signal is amplified and rectified in a voltage doubling circuit 38. The circuit 38 provides a negative output which is applied with a fixed positive bias to the grid of a trigger valve 40 which fires when the 3 kc/s. signal drops to zero. The trigger valve operates a neon indicator, an audible alarm or stops the thread processing line and continues to conduct until manually reset.
