Title: Improvements in processes of bleaching material
IPC: D06P1/00
Filed: 1922-04-01
Abstract: Material such as cotton, containing motes, shives, or leaf is bleached by treating in a hot bath having added thereto an acid dye, an acid and an alkaline oxidizing agent.  The preferred procedure is to wash the goods, say 100 lb., and pass them into a bath containing alkali blue, about 50 grains, at atmospheric temperature and leave them for 15 minutes.  Acetic acid about 2 lb. is added and allowed to act for a further 10 minutes to develop the colour, after which the bath is brought to a high temperature, preferably 170-180 DEG  F. About 7 lb. of the alkaline oxidizing agent is now added, such agent being preferably composed of about one half sodium peroxide and the other half caustic soda or a salt of an alkali metal, such as sodium chloride, soda ash, silicate of soda, phosphate of soda, or a mixture of these substances.  The bath is maintained hot for a considerable time, such as an hour and a half.  Specifications 103,445 and 158,531 are referred to.ALSO:Material such as cotton, containing motes, shives, or leaf is bleached by treating in a hot bath having added thereto an acid dye such as alkali blue, an acid, and an alkaline oxidizing agent.

Title: Improvements relating to ion-exchange processes for the treatment of liquids
IPC: C13B20/14
Filed: 1948-04-05
Abstract: 638,956. Purifying liquids. PERMUTIT CO., Ltd. April 5, 1948, No. 9492. Convention date, April 22, 1947. [Class 46] [Also in Group VI] In the ion-exchange treatment of liquids heavier than water such as sugar-bearing liquids in which the liquid is passed downwards through a bed 16 of ion-exchange material the normal flow of liquid during treatment is introduced e.g. from pipe 27 as by distributing pipes 17 beneath a stagnant body of water 19 maintained above the top of the bed 16 and when the bed 16 is to be regenerated the flow of the liquid under treatment is stopped, and water is introduced as by pipes 20 into the stagnant body to force the liquid in the bed downwards and out of the bed which is then subjected to a regeneration cycle including rinsing, and the liquid is re-introduced to displace the rinse water in the bed and thereafter to continue as normal flow. The effluent liquid first leaving the bed on the introduction of water e.g. via valve 22 into the stagnant body 19 prior to a regeneration cycle, being of satisfactory quality, is led to the same point of use 37 as the treated liquid in normal flow and the effluent liquid later leaving the bed and of not satisfactory quality is diverted to another channel such as 39. At the end of this stage of introducing water into the stagnant body when the specific gravity of the effluent liquid is practically that of water, the effluent liquid is diverted to another channel as e.g. pipe 41. When the recovery of this liquid is no longer economical valve 22 is closed and back wash water is supplied through valve 32 and discharged through valve 24. At the end of the back-wash stage, regenerating solution is supplied through valve 28 and pipe 17 and is discharged through valve 34 and the bed is then rinsed by water supplied through valves 22 and 30 and pipes 20 and 17 and is discharged through pipe 35. At the end of the rinsing stage the liquid under treatment again enters through pipe 17 and displaces the rinse water in the bed which water flows to waste through pipe 35 and when all this rinse water is displaced the normal flow of liquid treated is directed through pipe 37. Small amounts of water may periodically be introduced into the stagnant body as through distributing pipes 20 during normal flow of the liquid under treatment to cause the lowermost layer of the stagnant body 19 to be displaced into the liquid under treatment and while this displacement is happening it slightly dilutes the incoming sugar bearing solution and prevents the small amount of diffusion of the liquid into the bottom of the body 19 with consequent fermentation.

Title: Apparatus for producing synchronism between two or more machines
IPC: H02P5/46
Filed: 1963-03-11
Abstract: 1,032,192. Electric synchronized movements. ZEISS IKON A.G. March 11, 1963 [March 10, 1962; March 22, 1962], No. 9632/63. Heading H2L. Two machines to be operated in synchronism are driven by synchronous motors, one motor having a rotatably adjustable stator. Servomotor 18 adjusts the stator on starting to bring the machines into synchronism, and impulse generators, each coupled to a machine, control the servomotor to stop rotation of the adjustable stator when the machines attain synchronism. As shown, the impulse generators comprise rotary switches 5, 6; coupled to a camera and projector respectively, and associated with relay 10 shunted by capacitor 12 and in series with resistor 13. This relay controls switch 17 for motor 18. A lamp 19 indicates the attainment of synchronous movement, whilst signal lamp 21 is energized as long as the driving mechanisms do not operate synchronously. The lead 9 may be replaced by a radio link, and the impulse generators may each comprise a rotatable element co-operating with a coil or a perforated disc periodically interrupting a light ray directed upon a photo-cell. In another arrangement, a camera is started by actuating switch Ti to energize relay R1 whereby relay R2 connects camera-motor M to an A.C. source through resistor W. A stator brake St-B is energized to hold the stator stationary, the motor M rotating slowly to drive disc S1. The disc S2 is coupled to the master drive. Relay R6 is energized when contacts a, b of disc S1 engage, whereby relay R4 short-circuits resistor W, releases brake St-B, and operates rotor brake R-B. The stator now accelerates to full speed. Actuation of switch F1 energizes relay R5 to de-energize relay R4, the rotor being released, and the stator braked gradually by eddy-current brake W-B. As soon as the contacts a, b on discs S1 S2 are closed simultaneously, relay R7 responds to energize relay R3 and stop the stator.

Abstract: 107,810. Givler, R. C., and Givler, M. July 11, 1916. Kinematographapparatus. -Relates to cameras of the kind which includes mechanism whereby manipulation of an operating handle causes the film to be drawn out, and positioned relatively to the lens, and the shutter to be operated, intermittently, so that a succession of pictures showing different stages in the movement of an object may be obtained, and consists in a roll-spool camera in which the take-up spool may be manually operated inclependently of the shutter mechanism so that the film may be primarily positioned for the first exposure, or, if desired, a portion of the film utilized in making exposures in rapid succession followed by single exposures. The operating handle 70, Fig. 3, drives gearing 67, Figs. 1 and 3, by means of which the film spool is rotated and the shutter actuated. A multilated gear 71 prevents movement of the film while the cam 85 acting on the lever 86 operates the shutter. The shutter, Fig. 10, comprises a mutilated disk 22 having abutments 23 - - 28 and engaging a stop 29 to limit its oscillation. An escapement 31, attached to the lever 86, Fig. 3, carries a spring 32 which acts upon the disk 22. On oscillating the escapement, the spring 32 is strained and tends to move the disk 22. which movement is restrained until the wedge 33 on the escapement is removed from under the abutment 23 when the shutter will rotate until the stop 27 comes against the stop 29, during which movement the opening 35 moves past the lens c. The take-up spool 36, Fig. 1, is rotated by the gearing 36 and also may be rotated by means of the handle 43 when the mutilated part of the gear 71 is opposite the gear wheel 77. This position is indicated by means of indexes 95, 96. If single pictures are required, the gearing is set in this position and an exposure made by a slight movement of thehandle 70. The take-up spool 36 has a slot engaged by projections 91, Fig. 5, on the gearing and is supported at its lower end by a casing 40, Fig. 4, attached by ratchet gearing to the spindle 41 which carries the haudle 43. A carrier 60 engages flats 52 on the member 40 and holds the spool in position.

Abstract: 553,736. Moulding catalytic gels. HOUDRY PROCESS CORPORATION. Aug. 1, 1941, No. 9823. Convention date, Aug. 2, 1940. [Classes 1 (i), 1 (ii) and 1 (iii)] [Also in Group V] A continuous process for producing synthetic inorganic gels in granular form for use as catalysts consists in combining continuous streams of reacting solutions with agitation in a confined chamber, ejecting the mixture from the chamber as a substantially completely formed gel, drying the gel and forming into granules. As shown in Fig. 2, the solutions admitted at 11a, 11b may undergo primary mixing by an agitator 11c and then be injected tangentially into a chamber 10a into which a precipitating solution is admitted by circumferential ports 12a. The mixture is further agitated by the device 10b before leaving, this chamber. The gel is discharged on to a conveyer whereon it is drained and dried and after being broken up it is washed and if desired impregnated with suitable solutions of catalytic agents &c. After further drying and grinding the gel is moistened and subjected to mechanical' treatment to produce a paste, which is flowed into moulds and hardened therein. The moulds may be tapered holes in an endless belt 33a, Fig. 4, on to which the gel is spread in the form of a sheet by the action of mixing blades 101,. roller 102 and plate 113. A doctor blade 105 forces the sheet into the moulds and a second blade 105a removes surplus material from the lower surface of the belt and forces the contentsof the moulds upwards so as to protrude slightly from the upper surface, thus enabling the pellets, after drying, to be expelled from the moulds by the application of pressure to the protruding ends. The belt 33a circulates successively through a drying oven, under flexibleheating members which discharge the moulds, and through a washing device. Specifications 519,808 and 546,822 are referred to.
