Title: Contact sulphuric acid process
IPC: C01B17/78
Filed: 1929-05-27
Abstract: 314,858. Selden Co., (Assignees of Jaeger, A. O.). July 3, 1928, [Convention date]. Catalytic agents for the oxidation of sulphur dioxide comprise at least one diluted or undiluted leached permutogenetic body in which at least one catalytically active component is chemically combined in exchangeable or non-exchangeable form, with or without the presence of stabilizers or stabilizer promoters either chemically combined or physically associated with the base exchange body. The permutogenetic bodies mav be siliceous or non-siliceous, and may be prepared by methods such as those outlined in Specifications 279,466 and 286,212; they are leached with - acids or acid salts so as to remove part or all of the exchangeable and non-exchangeable bases. Diluents may be incorporated with the base-exchange bodies either during or after their manufacture; the diluents themselves may be base exchange substances. Alkali metal compounds may be added as stabilizers, and substances which are catalytically active but do not possess specific catalytic activity for the contact sulphuric acid process may be added as stabilizer promoters. The preferred catalytic element is vanadium. Specifications 290,316, 294,975, and 296,048 are referred to.

Title: Improvements relating to electric irons
IPC: D06F75/18
Filed: 1953-06-12
Abstract: 726,024. Hand-irons. HOOVER, Ltd. June 12, 1953 [June 27, 1952; Aug. 27, 1952], No. 16286/53. Class 138 (2). An electric steam iron has a sole plate 10 carrying or affording a flash boiler 12, a handle 17 and a cover shell 16 surmounting the sole plate, a reservoir 15 concealed by the shell 16 and communicating with the boiler 12 through a valve 28, a filler tube 37 secured to the top of the reservoir and having a forwardly facing filling opening 43 and a water port 42 opening into the reservoir near but short of the forward end thereof to enable the reservoir to be filled with the iron up-ended on its heel, and a venting port 61 opening from a point in the top of the reservoir forward of the water port to allow air to escape as water enters the reservoir through the water port. The capacity of the filler tube 37 may be substantially equal to the volume of air that will be trapped in the reservoir when the latter is filled to the maximum level A-A. Thus, when the iron is returned to the operating position the reservoir will be substantially full and the tube 37 substantially empty. As shown in Fig. 1, the outlet from the valve 28 may be below the maximum level A-A so that water may tend to flow into the boiler 12 if the valve is not closed. To prevent this a cupped fitting 70 having an outlet opening 71 above the level A-A is frictionally secured to a tubular flange 32 on the valve 28. Alternatively the valve orifice 30 may be of capillary dimensions. In a modification, Fig. 2 (not shown), the flange 32 is extended to a point above the level A-A, the fitting 70 being omitted. The valve 28 is closed by means of a valve stem 45 connected at 60 to an actuator 54.

Filed: 1937-06-11
Abstract: 488,965. Copying documents. RITZERFELD, W. June 11, 1937, No. 16288. [Class 100 (ii)] Relates to mirror-script duplicating-machines of the type in which an original mounted on a rotary drum 1 so that the lines of the script extend circumferentially is brought into contact with moistened copy sheets, and consists in mounting a counterpressing-device, such as a roller 8, and preferably also a damping- pad 6a, on a carriage 5 which is slidable parallel to the axis of the drum and is acted on continuously by a source of power tending to move it in one direction, and the movement of which is arrested either automatically in dependence on the rotation of the drum to allow equal movements of the carriage, or manually to allow either equal movements or any desired movement. The carriage 5 is constantly urged to the left in Fig. 2 by connection with a spring roller 10 and is brought back to starting position by turning a roller 12 also connected to the carriage. A rack 15 fixed to the carriage is engaged by a pawl 17b pivoted to a pawl 17a. When set for automatic movement of the carriage so that the script lines are copied in succession, a cam 33 on the drum 1 engages a lever 34 which moves a rod 21 to the left to move the pawl 17a up to the rack, the pawl 17b being meanwhile disengaged and a movement of the rack resulting owing to clearance between the pawl 17a and the teeth. The completion of the movement takes place when the pawls return to their former positions. The rod 21 may also be actuated by hand by depressing a lever 32a, and the pawl 17b may be actuated independently of the pawl 17a by pressing a lever 28a, the automatic device being disconnected in both cases.

Title: Improvements in or relating to electric projection lamps
IPC: H01J5/24
Filed: 1958-05-21
Abstract: 848,717. Making electric lamps. GENERAL MOTORS CORPORATION. May 21, 1958 [May 22, 1957], No. 16301/58. Class 39(2). A method of manufacturing a projection lamp having a reflector and a lens sealed thereto to enclose the lamp and surfaces on the lamp lying in a reference plane having a known orientation relative to the direction of light rays from the lamp, especially a vehicle headlamp of the " sealed beam " type, comprises mounting the reference plane surfaces on a fixed support, placing a control surface parallel to and spaced from the reference plane, maintaining the periphery of the lamp in a plastic state and deforming this until selected surfaces on the lamp lie in the control plane. The reference plane surfaces may constitute seating surfaces for the lamp when mounted on a support and are arranged for use with a geometrical aiming device. They may be in the form of bosses spaced around the periphery of the lens. For carrying out the process, lamps are indexed to successive stations for sealing and other operations in a turret machine and while the periphery is still in a plastic state reach a station at which the lamp is supported on a structure 54 having a finely ground surface 86. A double acting cylinder 64 then brings a spider 78 carrying an annular control ring 80 having a series of spacing pins 84 down on to the lamp until the pins 84 contact the surface 86. The control ring has a ground surface 82 and the, lamp lens has a set of aiming bosses integral therewith. Gas is then admitted to the lamp through a pipe 60 to stretch the seal until the bosses strike the surface 82. The pressure is then reduced and cooling air may be directed against the seal. The movement of the head, the supply of gas under pressure, the reduction of pressure, the supply of cooling air and the raising of the head are effected sequentially by magnetic valves 92, 94, 96, 89 operated by cams on a rotating shaft.

[Class 38 (iv)] [See also Group XL] Oscillation frequency.-In television, the line and frame frequency oscillations are derived from a common oscillator which is controlled by the phase relationship between the frame oscillation and an A.C. mains supply, so as to maintain a predetermined frequency and phase relationship with the A.C. mains supply. The A.C. mains supply also drives the film so that the scanning is correlated with the movement of the film. A blocking oscillator 15, Fig. 1, feeds a chain of similar oscillators 41, 43, 45, 47, each tuned to a sub-multiple of the oscillator 15 to produce oscillations of frequency 48 which control a sawtooth wave form generator 49 for controlling the slower deflection of the cathode ray beam. A similar generator 51, fed from the generator 15, controls the line frequency oscillation generator 53. The film 55 is intermittently driven by gearing from a motor 63 energized by the 60 c /sec. A.C. from the mains supply. The oscillator 47 feeds an oscillator 89 to produce a frequency equal to that produced by subdividing the mains frequency at 95. These two oscillations are then applied through wave shaping circuits 91, 97 to the input of a correcting circuit 71. This circuit comprises a valve 75 acting as a distorting amplifier or detector so that the current in the resistance 27 depends on the degree to which the two frequencies are out of phase. This current flow is used to bias the oscillator 15 to control its frequency.
