Abstract: 767,477. Control systems for X-ray apparatus. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. March 23, 1955 [March 26, 1954], No. 8403/55. Drawings to Specification. Class 38 (4). Control voltages representative of the selected anode voltage, discharge current and exposure time of an X-ray tube are applied to a valve which, if the selected values are such as would result in the overloading of the tube, conducts and causes operation of a relay which prevents energization of the H.T. transformer of the tube, the control voltage representative of exposure time being modified by a further voltage proportional to heat stored in the tube as the result of previous exposures. The control voltages are obtained from potentiometers connected across a D.C. source and ganged with the tube voltage, current and time selectors, respectively. The control voltage representative of exposure time is in the case of a proposed relatively long exposure, obtained from a potentiometer fed over a valve which is variably biased in accordance with the heat energy stored in the anode of the tube as the result of previous exposures: A further valve may cause operation of a second relay to deenergize the tube if the stored heat energy exceeds a predetermined figure.

Title: Method and apparatus for feeding wheel disc blanks
IPC: B21H1/02
Filed: 1925-03-31
Abstract: 247,771. White, A. E., (Budd Wheel Co.). March 31, 1925. Rolling.-In a machine for rolling discs on a rotating table 11 by descending rolls 35 to make tapered wheel discs, a fresh blank is placed on a feeding carriage 102, 107, which is swivelled horizontally about a pivot 101 by handle 117 until the new blank engages and pushes aside the finished blank and itself becomes deposited on the work table. The blank B, Figs. 1 and 2, is placed between an upper and a lower spring plate 110, 108, and centred by swinging down a spring pressed pin 114. Plates 110, 108 are secured to the lever 107 so as to rock between adjustable stops in a vertical plane about a pivot 105 secured between arms 102 which can swing in a horizontal plane about the fixed pivot 101. A spring 129 partly counterbalances the weight of plate B about the pivot 105. In action when the rolls 35 have ascended after finishing the blank A the whole carriage carrying the blank B is swung about the pivot 101 towards the centre of the table 11 by the handle 117 so that the blank B first engages the raised edge of the disc A and squeezes itself between the disc A and the table 11 until the raised edge of A engages the handle 115 when the disc A is prised off the centring stud 18 of the work table by pressing down the handle 117 to raise the plate B by vertical rocking about the pivot 105. Further horizontal swinging of the carriage pushes the plate A aside and is continued until the notched end of the plate 108 comes in contact with the centring stud 18 when upward movement of the handle 117 about the pivot 105 brings the hole of the blank B down over the stud 18 which thereby pushes the spring pressed centring pin 114 out of the hole and enables the carriage to be swung aside leaving the blank B in position on the table to receive the next descent of the rolls 35. A stop 130 limits the horizontal swinging towards the work table. The pin 114 is partly cut away to permit of free swinging back while when it is entered in the hole of the blank it is kept there by a lever 112 I'ig. 2 pressed by a spring 111. In case the rolls should descend and engage the blank before the feeding carriage has been withdrawn the action of the rolls on the blank would tend to turn the carriage against great friction about an axis 103 so that it would be swung away from the table. Specification 247,772 is referred to.

Abstract: 490,956. Refrigerating. ELECTROLUX, Ltd. April 1, 1937, No. 9289. Convention date, April 1, 1936. [Class 29] Absorption systems.-Vapour expelled in the generator 12 is led by a conduit 17 to a vessel 19 in the circuit of the strong liquor flowing from the absorber 39 to the generator, and by a vapour-lift action causes a local circulation of the liquor, independent of that produced in the usual lift pipe 15 of the generator, between lower and upper parts of the vessel 19. The vapour is thereby analysed or rectified. The vessel has a cross partition 20 from which depends a conduit 25 and through which passes the lift tube 22 having a small perforation 23 near its open lower end for producing the vapour lift. The upper end of the lift tube is directed towards the wall of the vessel 19 to diminish the noise of splashing. The vapour passes on through an air cooled rectifier 27 to a condenser 31. The strong liquor inlet 48 to the vessel 19 has a small aperture 49 to facilitate flow from the absorber at starting. The generator is of the horizontal type with a stand-pipe 14, and the condenser is in two parts from which parallel streams of refrigerant are fed through liquid seals to upper and intermediate parts of an evaporator 34. An inert gas circulates between the absorber and the evaporator through the usual gas heat-exchanger 38, and the parts of the condenser are connected with a storage vessel 56 for inert gas.
