Title: Improvements in or relating to Gas Burners.
Inventor: TURNER ERNEST
IPC: F23D14/10
Filed: 1917-01-29
Abstract: 108,502. Turner, E. Jan. 29, 1917. Perforated-tube and like multiple-jet burners. - In a multiple-jet burner in which gaseous mixture is supplied, to an internal tube or casing having apertures on the side opposite the flame orifices, the internal tube or casing is mounted, so that the position of its outlet apertures relatively to the imperforate surface of the outer tube or casing can be varied. Fig. 1 shows the application to a perforated-tube burner closed at its end by a cap b and provided with cross-slots a<1> having in some cases gauze or like metal coverings. The perforated inner tube f is mounted on trunnions i and rocked by means of a screw k in conjunction with a spring l. In a second form, the axis of the inner tube f may be inclined to the axis of the outer tube, and the inner tube may be eccentrically mounted. In a third form, the inner tube f, Fig. 4, is adjustable longitudinally by means of a screw o, and its inner end is provided with an orifice m and with a star-shaped guiding- member n to allow the passage of the gaseous mixture.

Title: Improvements in or relating to mechanism for intermittently rotating a shaft or other rotatable element
IPC: G04C13/11
Filed: 1921-04-11
Abstract: 186,089. Metcalfe, M. D. April 11, 1921. Electric clocks; clock movements.-Mechanism is provided for intermittingly rotating a shaft &c. comprising means for rotating the shaft through an angle less than 180‹ from the point at which the first means became operative, and is particularly applicable for driving electrical secondary clocks. The mechanism shown in Figs. 5 and 6 comprises an armature 14, on which is supported a closed tube 17 of mercury. On the energization of the electromagnets 15 by the impulse from the master clock, the armature is rotated into the position shown in Fig. 6 and the mercury then flows down the tube 17 and completes the half-rotation of the armature 14 when the magnets are deenergized. To prevent oscillation of the armature and tube after the rotation through 180‹, the flow of the mercury is retarded by means of flap valves 18 having apertures 19, Fig. 3. Fig. 1 shows an arrangement whereby such driving- mechanism is arranged to operate two sets of hands on opposite faces. The sets of hands are driven through shaft 12 and sleeve 38 respectively and these latter are interconnected by means of crown-wheels 37, 39 and pinions 43.

Abstract: 412,368. fluid meters. TONGUE, H., Chemical Research Laboratory, Teddington, Middlesex. April 8, 1933, No. 10609. [Class 54.] A piston valve 14 controlling the flow of fluid to and from a metering chamber 2 containing a displacement piston 1 is operated to reverse the direction of flow of the fluid through the pipes 9 by the piston at each end of its stroke engaging an insulated contact 4 and thereby completing the circuit to one of two solenoids 36 adapted to bring into operation servomechanism to operate the valve. The servo-mechanism may consist of a clutch element 25, which is continuously oscillated by an electric or other motor on a spindle 22 connected by a crank 21 and link 20 to the valve spindle, and clutch elements 29 which are feathered on the spindle 22 and are movable into engagement with the clutch element 25 by levers 34 connected to the cores 35 of the solenoids 36. The apparatus shown is particularly suited for metering gas at high pressure, the number of strokes made by the piston being indicated on a counter.

Title: Improvements in or relating to processes for the production of selenium rectifier elements
IPC: H01L21/103
Filed: 1952-05-01
Abstract: A selenium rectifier is produced by coating a base electrode with selenium and a non-halogen containing additive for increasing the crystallisation rate of the selenium, both the selenium and the additive being deposited simultaneously from the vapour state.  The additive is applied at least during the initially applied portion of the layer, but the amount may be varied throughout the layer.  The additive may be mixed with the selenium before vaporization, or the separate vapours may be mixed.  Suitable additive materials are ammonia and its derivatives, amines such as triethylamine, or organic compounds containing sulphur or selenium such as mercaptans e.g. alkyl mercaptans and sulphides and polysulphides e.g. dialkyl sulphide and dialkyl disulphide and the corresponding selenium compounds. Specifications 482,239, 486,073, 554,822, 623,459 [all in Group XXXVI], and 629,896 are referred to.ALSO:A selenium rectifier is produced by coating a base electrode with selenium and a non-halogen containing additive, for increasing the crystallisation rate of the selenium, both the selenium and the additive being deposited simultaneously from the vapour state.

Abstract: 669,353. Severing by tearing. LAMSON PARAGON SUPPLY CO., Ltd. (Moore Business Forms, Inc.). April 28, 1949, No. 11327/49. Class 31 (i). A machine for feeding continuous strips and severing the strips along longitudinally-spaced transverse lines is provided with a plurality of strip-feeding means spaced longitudinally of the strip path, means whereby the strip is fed first by one of said feeding means and then by another so that the combined action produces a continuous feeding of the strip, and additional feed means spaced from the first-mentioned feed means and operating so as to apply tension to the portion of the strip between the two sets of feed means so as to sever the strip transversely against a blade located between the two sets of feed means and adapted to engage the strip at a transversely weakened line thereof. As shown in Fig. 4, strip material S is fed to two pairs of feed rolls 17, 18, and 19, 20, and past a severing member 67 to a pair of snatch rolls 48, 50 which rotate at a higher speed than the feed rolls. The material is torn, along weakened lines, against the edge of member 67, the tear originating simultaneously at opposite sides of the strip and being completed in the centre. The feed rolls 18, 20, Fig. 6, have depressed portions 35, 36, along their surfaces so that although the strip is fed continuously, each pair of rolls feeds intermittently. The rolls are driven by a motor 56 through a chain 60. A guide 73 is provided to guide material from the feed rolls into the grip of the snatch rolls, which latter rolls are adjustable longitudinally of the machine.
