Title: Improvements in or relating to focal plane shutters
IPC: G03B9/34
Filed: 1940-05-08
Abstract: 537,068. Photographic shutters. KODAK, Ltd. May 8, 1940, No. 8277. Convention ate, Aug. 3, 1939. [Class 98 (i)] A focal-plane shutter of the type having two curtains so arranged that, on release, one moves relatively to the other to form the exposure slit, whereupon both move together to make the exposure, is provided with a speed-setting dial coupled to the shutter mechanism so as to vary the width of the slit and with manuallyoperable means carried externally on the camera which is coupled to the setting dial to adjust it, and is uncoupled from it by means operating during the first part of the movement of the release trigger. The invention is described as applied to a shutter of the kind described in Specification 529,297, tapes 37 from the first curtain being wound on rollers 38 and the second curtain 32 being wound on a roller 39. The shutter is wound by rotating a gear 41 by a mechanism which may be of the type described in Specification 513,738. The speed-setting knob 6 is mounted on a shaft 8 passing through a slot 9 in the camera wall and carried by a pivoted arm 10, the shaft 8 carrying also a gear 14 which engages a gear 15 carried by the speed dial 16, when the parts are in the position shown, so that rotation of the knob 6 adjusts the dial. The arm 10 is latched in this position by a lug 30 on it which is engaged by a lug 29 on a pivoted arm 20. Depression of the release button 28 swings a bell-crank lever 26 anti-clockwise which, through a connecting- rod 25, moves the arm 20 clockwise, the initial movement unlatching the arm 20 which is then given a small movement by a spring 12 to withdraw the gear 14 from engagement with the gear 15 and to move the knob 6 so that its edge protrudes through an open portion of the side wall of a recess 5 in which it is mounted. Further movement of the arm 20 causes a lug 22 on it to engage a pawl 23 to release the first curtain, which as it runs down rotates the gears 55, 55<SP>2</SP>, 55<SP>1</SP>, 48, the dial 16 and a dial plate 42 which it carries beneath it. Movement is transmitted from the gear 48 to the plate 42 by a spring clutch 46, one arm 45 of which engages in radial notches in the plate, but allows the dial to be rotated to adjust the speed after winding the shutter. After a degree of movement determined by the initial setting of the speed dial, a pin 49 projecting downwardly from the dial plate strikes a lug 50 on an arm 51, causing it to rock the shaft 52 on which it is mounted, so that a pawl 53 on the same shaft is disengaged from a single-toothed ratchet 54 secured to the roller 39 of the second curtain, which is thus released. At the same time the pawl 53, which before its movement engages the tail of a pawl 56 on the ratchet disc 54, releases this second pawl, which then engages a tooth of a ratchet 61 secured to roller 38, thus latching the rollers 38, 39 together. Both curtains then move together with the previously-established slot between them,

Abstract: 116,528. Osborne, W. H. June 11, 1917. Spring devices.-In link-mounted spring forks for motor-cycles &c. so constructed as to provide for a substantially vertical movement of the fork and also for a substantially horizontal movement of the wheel, the same spring provision is used to intercept the vibrations in both actions of the fork and is arranged to operate directly between the steering-column and the fork. The horizontal movement of the wheel may be provided for by coupling either the lower or the upper link or links to an element pivoted to, or adapted to slide in relation to, the fork, and the spring provision may consist of one or more laminated springs. As shown in Fig. 1, a single spring b, anchored at its rear end to a lug a on the steering-column, is provided at its front end with a scroll c connected to one or more fixtures d on the fork e. A transverse member k, extending from one side of the fork to the other or constituting part of a stirrup pivoted to the fork, is adapted to come into contact with the under surface of the spring b. The front end of the spring b may, however, be of U- form with the upper limb coupled to the fork. Or a spring, anchored to the upper part of the steering-column, may be furnished at its lower end with a scroll secured to the fork; or the spring may be fixed at a mid-position to the fork and coupled at its lower end to the link g, the upper end being in the form of a scroll connected to a forwardly-extending lug in the column.

Title: Improvements in or relating to the recovery of sulphur from gases
Inventor: MARSH JOHN DAVID FRANCIS
IPC: C01B17/04
Filed: 1952-04-01
Abstract: In the continuous recovery of sulphur from hydrogen sulphide-containing gas by passing the gas after partial combustion through a first stage catalyst chamber at a temperature sufficiently high to prevent condensation therein of the sulphur produced, separately condensing the sulphur, and then passing the remaining gases through a second stage catalyst chamber at a temperature such that sulphur condenses on the catalyst, revivification being carried out during the process by employing at least two second stage catalyst chambers and revivifying one while the other is on stream by the passage therethrough of a gas at such a temperature as to vaporize the sulphur and passing the resulting gaseous mixture to the main process stream prior to the sulphur condenser, the ratio of hydrogen sulphide to sulphur dioxide in the gas stream after the sulphur condenser and before the second stage is continuously determined and restored to a predetermined value by adjustment of the total air employed for the partial combination.  The ratio is desirably such as to give the optimum yield of sulphur in the overall process, which ratio is found by experiment as that giving the lowest concentration of sulphur dioxide and/or hydrogen sulphide at the outlet of the second stage.  Alumina and compounds of titanium are preferably employed as catalysts in the second stage.  The catalyst may be present as a static bed, preferably of shaped pieces or broken granules of a size of for example 1/8 to 3/8 inch. Revivification may be effected using an oxygen free gas, for example gas from the main process stream at any point after the sulphur condenser, or by an oxygen-containing gas.  In the latter case part of the sulphur is burnt, the heat thereby produced assisting in the vaporization of the remainder, and the resulting gas is returned to the main process stream prior to the first stage.  The catalyst bed may be heated during revivification by electric heaters or heat transfer media.  In the latter case heat available from the first stage may be employed in the second stage.  A jet pump may be employed to recycle the gases for regeneration, using part of the momentum of the gases leaving the first stage reactor.  Specifications 622,324 and 695,496 are referred to.

Title: Improvements in or relating to an apparatus for preshrinking a web of fabric
IPC: D06C21/00
Filed: 1947-03-31
Abstract: 632,516. Shrinking fabrics. MUNSING- WEAR, Inc. March 31, 1947, No. 8617. Convention date, May 13, 1940. [Class 42 (i)] Apparatus for pre-shrinking a web of knitted fabric comprises a steam chamber through which the fabric is passed, a pair of endless elastic belts having adjacent runs between which the fabric is fed after steaming and means for positively driving the receiving ends of the belts relatively faster than the discharge ends. Drying means is preferably provided after the fabric has emerged from between the belts. The fabric is withdrawn from a roll 6, on a core 7, and supported on an idler roll 5 in a standard 4, and passes through a steam chamber 29. It is then received between the belts 21, 22, running over the rolls 9, 16, and 11, 17 respectively, and having adjacent runs 23, 24 in fabric-feeding contact. The rolls 9, 11 are positively driven at a greater peripheral speed than the rolls 16, 17 so that the belts 21, 22 contract as they enter the runs 23, 24. After emerging from the belts, the fabric passes through a drying chamber 41, and over a roll 46 driven at the same surface speed as the roll 16 by a chain 47, and is collected in a roll 42 rotating in contact with the roll 46. The differential peripheral speed of the rolls 9, 11 and 16, 17 may be obtained by making the former of greater diameter than the latter and driving them all at the same speed, or by the arrangement shown in Fig. 2 in which each pair of rolls is geared together, and a chain 36 drives sprocket 37 on the shaft 19 of the rotor 17 from a sprocket 38 which is mounted on the main drive shaft 31 of the apparatus. A gear 34 on the shaft 31 meshes with an intermediate gear 33 carried on a pivoted arm 32, a change-gear 35 removably secured to the shaft 13 of the roll 11 meshing with the gear 33 and permitting the speed of the rolls 9 and 11 to be varied. The rollers 25, 26, 27 and 28 may idle in contact with the belts 21, 22, or they may be positively-driven from the rolls 9 and 11 through a belt or chain drive at successively decreasing speeds, in order to render the contraction of the belts more gradual. They may be staggered, as shown, or arranged in opposed pairs.
