IPC: B21B39/08
Filed: 1963-06-04
Abstract: 1,080,842. Rolling. UNITED ENGINEERING & FOUNDRY CO. June 1, 1964 [June 4, 1963], No. 22141/63. Heading B3M. [Also in Division B5] A method of controlling the flatness of strip during reduction in a rolling mill comprises subjecting the strip to longitudinal tension which varies transversely of the strip to reduce different elongations of the strip across its width caused by the reduction. Strip 5 from the work rolls 11 of a four-high mill passes around bridle rolls 14 and 15, over a roll 25 and to a coiler 17. The roll 25, Fig. 3, has a working portion 26 mounted in bearings 22 and 23 on a rigid support 21. Further bearings 31 and 32 are movable vertically by means of hand wheel operated jacks 33 and 34, to cause bending of the portion 26 and to provide a consequent differential tension across the strip. A motor drives the roll at the same speed as the strip. In an alternative form the roll 25 is replaced by a roll pair between which the strip passes. The upper roll is convex and the lower once concave, the rolls being moved vertically as a unit so that the strip contacts one or other roll according to whether increased tension is desired at the centre or edges of the strip. The tension device may be positioned in front of the roll stand.

Vacuum tubes; Low-pressure metallic-vapour apparatus.-A vessel, such as a mercury-vapour rectifier, which is evacuated to a pressure of a few microns of mercury has a glow-discharge device mounted in or communicating with the vessel and provided with electrodes between which a discharge takes place only when the pressure within the vessel is within predetermined limits, the discharge device being connected with a relay controlling the main switch of the rectifier; a pressure-responsive device, such as a manometer gauge, is connected with the vessel and serves to open the main switch when the pressure in the vessel exceeds that at which the glow discharge can be maintained. As shown, the glow discharge device 13 has electrodes 17, 18 spaced by a tubular insulator 23 closely surrounding central projections 19, 20 on the electrodes. The electrode 18, which may be formed with the projection 20 separate from the remainder, extends into a pipe 14 leading to a mercury-vapour rectifier 4, and a tortuous channel connects the pipe 14 with the inside of the device. The device is connected with the secondary of a transformer the primary 29 of which is connected through the winding of a relay 40 of the wattmeter type with an alternating- current supply. When the pressure in the rectifier increases beyond the predetermined limit, a discharge passes in the device 13, and the relay 40 closes a contact 41 to energize the opening coil 10 of main switch 8 of the rectifier, and to energize the winding 42 of a relay so as to de-energize the closing coil 9 of the switch 8. The relay 40 may also trip the coil of a master controller, so that the rectifier cannot be started except by hand, or a manometer 47 may be provided which, at a pressure of one-half to one millimeter of mercury, completes the circuit between two columns of mercury so as to close the circuit of the relay 42. In the modification shown in Fig. 4, the discharge device consists of an electrode 60 surrounding a central electrode 61 which is enclosed in an insulating sleeve 62 and has a tip 63 of carbon or graphite.

Title: Manufacture of hydroxylamine hydrochloride
IPC: C25B1/26
Filed: 1938-07-27
Abstract: 517,436. Electrolytic production of hydroxylamine. I. G. FARBENINDUSTRIE AKT.-GES. July 27, 1938, No. 22350. Convention date, Aug. 17, 1937. Drawings to Specification. [Class 41] [Also in Group III] Hydroxylamine hydrochloride is obtained in the solid state following the electrolytic reduction of a mixture of nitric acid and hydrochloric acid in a diaphragm cell by continuing the reduction in the cell until the catholyte is nearly saturated with hydroxylamine hydrochloride removing the catholyte from the cell, and introducing gaseous hydrogen chloride into the catholyte, while cooling, whereby hydroxylamine hydrochloride separates in a solid state. The process may operate continuously the mother liquor remaining after the separation being reconducted to the cathode compartment of the cell after the consumed nitric acid has been made good. The small increase in volume of the catholyte formed during the cycle by the addition of the nitric acid, the addition of the washing lye for the separated product (if such is employed), or electric osmosis, may be separated and saturated with further hydrogenchloride while strongly cooling, until hydroxylamine hydrochloride has precipitated nearby completely, the remaining mother liquor being added to the anolyte with a corresponding removal of anolyte from the system.

In a carburetter comprising means defining an air passage, an air control valve in the air passage, a venturi or similar constriction for producing a low pressure region in the air passage downstream of the air control valve, at least one rich mixture producing carburetter delivering substantially its entire mixture into the low pressure region, the rich mixture producing carburetter comprising means defining a carburetter passage, a mixture producing stage in the carburetter passage, a fuel jet at the mixture producing stage and a throttle valve in the carburetter passage and means operatively connecting the air control valve and throttle valve for associated movement, the throttle valve comprises a movable apertured plate valve operatively associated with the carburetter passage providing a variable effective opening. In Fig. 3 rich mixture is formed in passages 67, 66 brought into operation alternately by means of a slotted plate valve 62 controlled conjointly with an air control valve 78. The idling arrangement comprises a passage 76 and adjustable needle valve 77. A simpler form of Fig. 3 is described in which there is one rich mixture passage only and the axis of the venturi is vertically disposed. The idling arrangement comprises an air inlet controlled by a thumb screw and a separate fuel nozzle. In Fig. 5 a slotted plate valve 91 controls the main air inlet 84 and an idling passage 89 and rich mixture passage 88. Figs. 6 and 7 show a further embodiment comprising a notched plate 108 which controls a main air inlet 102, and rich mixture passages 103, 104. An idling passage 105 is provided. The passage 104 includes an adjustable restriction 117 which is preferably controlled by the operator. When the valve 108 is rotated fully to the left all the passages except the passage 105 are closed. During idling fuel is drawn through the transverse passage 118 and mixed with air in the passage 105. For low load operation passage 109 is opened while for higher engine loads the rich mixture passage 111a is opened and at the same time air is permitted to flow through the passage 111. It is stated that the so called low load rich mixture carburetters may operate up to 70 per cent of the load. The restrictions in the idle and slow speed passages need not be venturis. Usual compensating mechanisms may be incorporated. The plate valve need not turn about an axis but could have a rectilinear motion. An additional valve could be provided anterior to the fuel jet or air control valve. The air and mixture control valves may be connected by compensating connections which may compensate for altitude and temperature changes &c. The carburetter may be supplied with air under pressure instead of drawing it from the atmosphere. There could be more than two rich mixture carburetters with a corresponding number of gate apertures.
