Patent GB-1102943-A (GB)
Title: Separation of acidic gas constituents from gaseous mixtures containing the same
IPC: B01D53/52
Filed: 1966-01-11
Abstract: Acidic gas constituents such as hydrogen sulphide, carbonyl sulphide and carbon dioxide contained in gaseous mixtures e.g. ammonia synthesis gas are separated by contacting the gaseous mixture with a solution of an alkanolamine in a dialkyl ether of a polyalkylene glycol so as to effect absorption of the acidic gas constituent in the solution.  The solution containing absorbed gas is passed to a heated stripping zone, maintained at a pressure substantially lower than that during the absorption, in the presence of water, thus desorbing gas, and the stripped solution recycled.  The alkanolamine may be dissolved in a dimethyl ether of a polyethylene glycol or a mixture thereof.  The alkanolamine may be propanolamine, butanolamine, or diisopropanolamine.

Title: Improvements in mechanism for operating perforators, numbering or like devices on printing presses
IPC: B41F33/04
Filed: 1949-01-17
Abstract: 664,421. Printing-machines. LEECH, R. April 17, 1950 [Jan. 17, 1949], No. 1305/49. Classes 100 (i) and 100 (ii). In a mechanism for actuating and controlling the actuation of perforators numbering or like devices for use in a printing press of the kind in which an operating lever 3 depressed by the impression cylinder, or platen, slides a bar 12 for operating the device, and by means of a pawl 5 and ratchet 6 rotates periodically an exchangeable control wheel or cam wheel 13 controlling the operation of the device so that it is operated, as desired at each printing operation or after a predetermined number of printing operations, the operating lever 3 is provided with a tappet 11 which, under the control of the cam wheel 13, is moved into or out of operative position between the lever 3 and the sliding bar 12 so that when the tappet is in operative position the operating lever can make a direct thrust through it on the sliding bar, but when the tappet is in inoperative position the operating lever has no effect on the sliding bar. The tappet is normally held in its inoperative position by a spring 15 so that it slides above the bar 12 but is pressed down to its operating position whenever the end 14 of a spring-loaded bell crank 22 which engages its upper surface enters a depression in the cam wheel 13. The cam wheel 13 is secured to or integral with the ratchet 6 and the shaft 7 on which they are mounted can be removed from the device to enable the cam wheel to be changed.

Abstract: 1487653 Firearm BOFORS AB 14 Jan 1975 [15 Jan 1974] 1598/75 Heading F3C A device for supplying ammunition to a firearm 1, Fig. 1, comprises magazines 3, 4 to be arranged one on each side of the firearm as well as equipment for automatic loading of the firearm with rounds inserted in the magazines, each magazine 3 or 4 has holding members 9 for supporting rounds of ammunition, said holding members forming part of an endless chain and having their longitudinal axes parallel to each other and, in use, to the barrel of the firearm, feed out positions 10, 10<SP>1</SP>, and has a loading-car for transporting a round fed-out from the feedout position to a ramming position coinciding with the axis K of the bore of the firearm. The holding members 9, Figs. 4 and 5 each carry two rounds and are provided with guide rails 54, 55, stub shafts 56 and lugs 57, 58, 59, and coact with wheels 50, 51 on respective shafts 48, 49. Alternatively, the holding members are star-shaped wheels 86, Fig. 9, on respective axles 87. A longitudinal feed mechanism has a tubular unit 41, Fig. 6, which contains a piston 60 having a piston-rod 61 connecting to a feeding head 62. A feeding tooth 42 is carried by the feeding head 62 and extends through a slot 63 in the unit 41 in order to engage a flange 69 of a round 39<SP>1</SP> which is in the feed-out position. In an embodiment loading cars 11, 12, Fig. 1, are provided with a respective loading tube 21, 22 for holding a round fed-out from the magazine 3 or 4, the loading tubes each being displaceable in a longitudinal direction and each having a rammer head 33 mounted therein. Each loading tube has flaps for retaining a round therein while the latter is being transported from the feed-out position to the firearm. The loading tubes can be used alternatively. In operation the rammer head grasps the flange of the outer round which is in the feedout position and transfers it to its loading tube and the inner round is moved rearwardly to the position from which the outer round has been removed. The loading car of the loading tube is actuated in the longitudinal direction to the ramming position. When the loading tube is in alignment with the axis of the bore of the firearm it is displaced axially into engagement with the breech ring. The rammer head moves the round into the bore of the firearm, the breech block moves to its closed position and the rammer head, along with the loading tube, returns to the position where the loading car can move transversally to the feed-out position. At the same time as this takes place, a round is fed-out of the other magazine into the loading tube of the other loading car. The latter is now ready to move its inserted round to the ramming position as soon as the round already in the firearm has been fired and its cartridge case has been removed from the barrel; the loading continues alternatingly until the required amount of ammunition has been fired.

Filed: 1967-01-12
Abstract: 1,146,373. Photo-electric detection of defects. GENERAL ANILINE & FILM CORP. Jan. 12, 1967 [Jan.13, 1966], No.1685/67. Heading G1A. Defects in a moving web are detected using a "flying spot" scanning system utilizing a plurality of bent optic fibres oscillating or rotating to produce spots of light moving across the web, a further plurality of bent optic fibres, oscillating or rotating in alignment and synchronism with the first plurality, being used to view the light spots reflected or transmitted by the web and to transmit light to a common fixed detector. In an arrangement in which light is transmitted through the web, Fig. 3, two optic fibres 25 are mounted in a holder 84 having a disc shaped portion 90 and a neck portion 88. Light from a lamp is filtered to pass only infrared light, which is passed by an optic fibre to light guide 105 into a chamber 103 adjacent the ends of fibres 25. Light is transmitted by the fibres 25 and is formed by lenses mounted in holders 99 into spots on the web. A holder 109 carries other optic fibres whose ends nearer the web are directly opposite the ends of fibres 25. The other ends are bunched together and feed a photo-multiplier. The holders 109 and 84 are carried in bearings 82, 83 and are rotated in synchronism by a pulley system. As the web moves, while the holders rotate, the effective scan of the spots from the optic fibres 25 is in the form of a flat helix. In an arrangement for investigating the web material by reflection Fig. 4 (not shown), light directing and receiving optic fibres, mounted on the same side of the web, are oscillated back and forth in synchronism, instead of being caused to undergo complete rotation. The optic fibre may be a quartz fibre, a coated glass tube or a rod of transparent synthetic resin e.g. polystyrene, P.V.C. or polymerized acrylic acid esters.

Abstract: 372,712. Gear-cutting. AEPPLI, A., 219, Hardstrasse, Zurich, Switzerland. Jan. 20, 1932, No. 1800. Convention date, Jan. 20, 1931. [Class 83 (iii).] In an attachment 2 designed to render a gear-cutting machine, such as that described in Specification 109,256, [Class 83 (iii), Metals, Cutting], in which external gears are generated by means of a reciprocating rack-cutter 1a, applicable to the generating of internal gears 10, the rack-tool is replaced by a pinion-cutter 7 which is rotated in unison with the blank so that its pitch circle rolls on the blank pitch circle. The attachment is adjustably secured by screws to the ram 1 of the machine and has bearings for a shaft 3 on which is pivoted a housing 4 provided with bearings for a vertical shaft 6 carrying the pinion-cutter. The cutter position during operation is determined by a machined surface 5 on the housing which engages a corresponding surface on the attachment body. The work-table 11 is normal!y rotated from a shaft 16 through bevel gearing 15, change-wheels 14, shaft 36, and worm gearing 13. The pinion-cutter is driven from the shaft 16 through bevel gearing 19, vertical shaft 17, bevel gearing 18, shaft 3, and worm gearing 9. In working normally with a racktooth cutter the blank table is moved laterally in unison with its rotation by means of a shaft 22. When the attachment is used this lateral movement is not required and the gear 21 engaging one of the change-wheels 14 is accordingly disconnected. The generating movement is effected during the return stroke of the ram and in order to remove the tools from the work during the return the machine frame is fitted with friction-blocks 44 engaging a rod 26 connected by an arm 25 to a cam shaft journalled in the body of the attachment and carrying a cam 23. During the working stroke the arm 25 is dragged upwardly and forces the cam 23 against a projection on the housing so that its stop surface engages the surface of the attachment but during the return movement the cam engages a projection 42 on the housing 4 thus lifting the housing and the cutter away from the work.

[Class 100 (i)] [Also in Group XVII] In an apparatus for feeding paper, film, foil or other material to wrapping machines a controlling member moves into engagement with the leading edge of a wrapper, so as to control such edge during the feeding movement, an attractive force induced by a charge of static electricity, existing between the wrapper and controlling member to effect such control. Wrapping material in web form 11 is fed over a table 12 by feed rollers 14 towards a cutting device 13 beyond which the leading edge of the web is supported by the controlling member 17 having a surface layer 18 of material susceptible to a static charge. The member 17 moves with the same speed as the web 11 and in the same direction towards folders 22. When the web reaches the folding station the feeding motion is stopped and the cutting device 13 severs a wrapper 16. An article 19 supported on a platform 21 is moved upwardly into engagement with the wrapper 16 and into a pocket 23 of a member 24 rotatably mounted on a shaft 26. The controlling member 17 them moves into contact with a brush 27 to restore its static charge. The movements of the member 17 are controlled by cams 34 and 38. The web may be given a static charge in place of the surface 18 of the member 17.

Title: Improvements in or relating to electronic threshold circuits

Filed: 1971-01-14
Abstract: 1292562 Electric retroactive control of fuel feed to engine FIAT SpA 14 Jan 1971 [21 Jan 1970] 1855/71 Heading G3R Fuel feed to a vehicle diesel engine is controlled in dependence upon magnitude of exhaust temperature, by a circuit arranged to provide one of two output signals in dependence upon whether a temperature dependent control signal is, respectively, greater than a first threshold or less than a second threshold. The exhaust temperature is sensed by a thermocouple 8 the output of which is added to a voltage from pot divider R7, R8 and the sum is applied as a control signal to input 5 of a differential amplifier 1. A reference signal from R2, R3 is applied to input 4. When the thermocouple voltage is less than a predetermined value the output of the amplifier is high and positive feedback via R9, R10 keeps the reference voltage at 4 at a high level. There is thus determined a first threshold value for the control signal below which the amplifier output is maintained in a first state. When the thermocouple voltage exceeds a certain value the voltage input at 5 tends to exceed that at 4. The amplifier output thus decreases so that the positive feedback via R9, R10 tends to reduce the input at 4 thus establishing a second threshold value for the control signal. Zener diodes 12 stabilize the output voltage at point 13 and define precisely the value of variation of thresholds which operate via R10. Due to R9 the voltage at point 14 may be subject to variations although the voltage at 13 remains stabilized. Transients in the control signal due to interference are absorbed by the integrating effect of C11 in a negative feedback path, which affords a response delay. The circuit assumes simultaneously both bistable and integrating behaviour. A resistor R9 is such as to provide temperature compensation and to compensate for the thermal e.m.f. of the cold  junction of thermocouple 8.
