Title: Improvements in or relating to apparatus and processes for treating and ageing fabrics
IPC: D06P1/22
Filed: 1929-08-29
Abstract: 334,069. Chapin, E. S., and Jacoby, A. H. Aug. 29, 1929. Gases and vapours, treating with. - In the treatment of material after vat dyeing or discharge printing, a fabric x, passing continuously over rollers 8, 9 in a tank 1, is aged or reduced in an atmosphere of steam vapour supplied from a mixing chamber 24 and admitted under a screen 10 bv perforrated pipes 34, the excess heat given off by the actions of the heat and moisture upon the fabric and the dyes being dissipated and varying circulation conditions at successive stages being obtained by a wider spacing of the rolls in the forward portion of the chamber where the generation of heat is more intense. Steam of the proper pressure, temperature. and water content, for use in the ager, is prepared in the mixing chamber by admitting steam and water through pipes 15 and 27 respectively, the supply of each being regulated by hand valves. Steam-heated plates or chests 7 prevent condensation of moistune at the top of the ager, whilst a suction device 4 carries away the steam that would tend to be discharged through the opening 3.

Abstract: 243,884. Baker, Ferhins, Ltd., and Prescott, W. E. Nov. 5, 1924. Cam-actuated pumps; drip, preventing; oscillating-cylinder pumps.-In a machine for making wafer biscuits, the batter supply is provided with an auxiliary pump which is operated, after a plate is filled, to draw the batter back from the nazzle and prevent dripping therefrom. In Fig. 4, the auxiliary pump is mounted on the oscillating system carrying the swinging nozzle arm which is secured to the flange 20 of the pump. The pipe 4 is oscillated by a reciprocating rack engaging a pinion on the pipe, and the auxiliary pump is oscillated therewith. The plunger 21 carries a roller 24 which engages a cam face 25 on a stationary cam member 26, the plunger being withdrawn for the suction stroke until the point 25a is reached. On the return oscillation the roller 24 moves along the face 26a and presses back a spring-pressed block 27a having an inclined face 27, the said bloelbeing urged out by the spring after the roller has passed. On the roller 24 moving again to the lelt, Fig. 4, it rides up a cam face 31 on the block 27a and is again placed into contact with the cam face. 25. Guides 23a for the plunger 21 are provided. In a modification, the invention is applied to the batter supplying device described in Specification 10000/06 in which the supply pump reciprocates bodily. The auxiliary pump is mountel on the reciprocating parts and its plunger contacts at the end of each stroke with adjustable stops.

Patent GB-1107307-A (GB)
Title: Process for separating straight-chain olefines
IPC: C10G25/03
Filed: 1965-06-24
Abstract: A process of separating straight chain olefins from hydrocarbon mixtures comprises adsorbing the olefins on a molecular sieve, suitably a zeolite, which has previously been saturated with ammonia or a C1-2-alkylamine, and then eluting the adsorbed olefins with ammonia or a C1-2-alkylamine.  The entire process is carried out in successive cycles at a uniform temperature of 20-200 DEG C, and preferably 100-180 DEG C.  In a particular embodiment, two beds of a 5  zeolite are used.  The hydrocarbon mixture is passed over one bed, while ammonia or amine is passed over the other to effect desorption of straight chain olefin adsorbed previously and to pretreat the bed for a subsequent adsorption cycle.  In another embodiment, three zeolite beds are operated cyclically.  Over the first is passed the gas mixture to be separated, over the second is passed ammonia or amine to desorb the straight chain olefins previously adsorbed, and over the third is passed treated gas from the first stage, thereby desorbing ammonia or amine and removing the remainder of the straight chain olefins from the treated gas. Particular applications include the separation of butene-1 and butene-2 from C4-hydrocarbon mixtures. Reference has been directed by the Comptroller to Specification 842,431.

Filed: 1929-09-05
Abstract: 318,633. Kodak, Ltd., (Assignees of Clarke, H. T., and Othmer, D. F.). Sept. 8, 1928, [Convention date]. Formic acid.-Aqueous formic is concentrated by mixing with n-propyl formate and distilling off a mixture of water and n-propyl formate at a temperature below the boiling point of water. Alternatively n-propyl alcohol may be added which will form n-propyl formate in situ. In the preferred form of apparatus, aqueous formic acid from a reservoir 38 is' fed into a fractioning column 41 and sprayed with npropyl formate from a nozzle 42. Water and n-propyl formate pass by a pipe 46 to a condenser 47 and the condensate separates into two layers in a vessel 49, the upper formate layer being confined by a downwardly depending partition 50. This layer is drawn off by a pipe 53 and recirculated to the nozzle 42. The aqueous layer is sprayed through a nozzle 71 into a column 72 wherein it is flashed " with steam to remove any residual n-propyl formate which is condensed in the condenser 75 and passed to the separator 49. The mixture of anhydrous formic acid and n-propyl formate collecting in the heater 44 is fed into a column 55 from which the vapours of n-propyl formate pass to a condenser 59 and are then recirculated in part to the nozzle 42 and in part to a refluxing nozzle 65. Anhydrous formic acid collecting in the stil bottom 56 is preferably refractionated in a further still 67. Specification 303,742 is referred to.

Abstract: 716,165. Television receivers. STANDARD TELEPHONES & CABLES, Ltd. Oct. 31, 1952 [Dec. 14, 1951], No. 27436/52. Class 40 (3) In a television receiver, the apparent definition of the received image is increased by adding harmonics derived from fundamentals occuring in the upper half of the video signal frequency band to the original video signal. Thus, as shown in the Figure, the output of the video detector 2 is applied to the cathode of the cathode-ray tube 5 through a 0-4 Mc channel comprising amplifier 3 and delay circuit 4, and also the grid through a second channel which selects components in the 2-4 Mc range and generates harmonics by distortion. The components are selected by bandpass amplifiers 6, and a biased valve stage 7 passes and squares only signals above a preset level. This has the effect of eliminating harmonics of signals in the 0-2 Mc range which are of smaller amplitude than fundamentals in the 2-4 Mc range. The output from stage 7 in the 4-8 Mc range is selected by filter 9 and passed to the C.R. tube grid: Circuit 4 introduces a delay equal to the propagation time of channel 6-9.
