Title: Process for steaming fabrics
Inventor: JAMIN GILLAUME WARD
IPC: D06B19/00
Filed: 1964-10-29
Abstract: Apparatus for steaming textile material comprising a chamber having a steam inlet and an opening to the exterior atmosphere, means for maintaining a temperature above 120 DEG C in the chamber and means for progressively advancing the material into and through the chamber.  In the preferred embodiment, Fig. 1 (not shown), the chamber comprises a cylindrical tower (1) having a centrally disposed heater (5) and an externally lagged jacket (3); the heater (5) and jacket (3) being heated by flow of heating fluid, electricity or other means.  The heating fluid is preferably pressurised steam which flows, for example, through spiral pipes 6.  The textile material is guided through the chamber in close proximity to the heater (5). Steam is introduced into the chamber by means of a perforated pipe (12), the steam being sprayed onto the walls of the chamber and is thus heated to a temperature above 120 DEG C.  In an alternative embodiment, Fig. 3 (not shown), a plurality of guide rollers (26), (27) and heating panels (29) are provided so that the textile material follows a zig-zag path between the panels.  A further embodiment, Fig. 5 (not shown), employs a plurality of guide rollers (46) and heating panels (51), (52) so arranged that the textile material follows a progressively decreasing circular path through the chamber.  Examples given of processes effected using the apparatus of the invention include the fixation of dye on textile material and the fixation of fluorescent brightening agents on cellulose, protein or synthetic textile materials.

Abstract: 1,205,142. Spray carburetters. FORD MOTOR CO. Ltd. Sept.18, 1968 [Sept.29, 1967], No.44265/68. Heading-F1B. The flow in the idling system is controlled by a valve 52, Fig. 1, operated by the suction downstream of the throttle valve. In Fig. 1, the valve 52, attached to a suction operated piston 48,controls the amount of bleed air flowing into the idling passage 24. As the throttle valve begins to open and the manifold suction decreases, valve 52 restricts the bleed orifice 28 to increase the suction in the idling passage and thereby increase the idling feed supply. The valve 52 may alternatively control the idle fuel orifice 32 or an orifice 35 in the idling passage 24.

Title: Heat exchangers
IPC: F28D7/02
Filed: 1960-12-28
Abstract: 924,970. Forced flow steam boilers. SULZER FRERES S.A. Dec. 28, 1960 [Jan. 29, 1960], No. 44510/60. Class 123 (2). In a vapour generator heated by a transfer fluid, for example pressurized helium used as the coolant of a nuclear reactor, and generating vapour at a high and a low pressure, the heating fluid flows serially through nested chambers disposed within a pressure vessel and in which are located the tubulous heating surfaces of the generator. The Figure shows the vapour generator of a marine nuclear power plant. It consists of pressure vessel 1 with helium coolant inlet and outlet ports 2, 12. Within the vessel are disposed concentric partitions 3, 5, 7, 9 dividing the interior into a central chamber a communicating with the inlet port 2 and annular chambers b, c, d, e, all of the same cross-sectional area. End baffles 4, 6, 8, 10, 11 cause the gas to flow serially through the chambers, the outermost chamber e communicating with the outlet port 12. Each chamber contains tube helices forming the boiler heating surfaces, the coil pitches increasing outwardly so that the tubes of all the helices are of the same length. The high pressure (170 atm.) liquid enters through a tube 13 connected to a header 14 and flows successively through coils 16 in chamber e, connecting tubes 17, coils 18 in chamber c, connectors 19, coils 20 in chamber b and a header 21 to a separator 23. Vapour flows from the separator to a header 25 and thence through superheater coils 26 to a header 27 whence a tube 28 conveys the high perssure vapour to the point of use. Low pressure (50 atm.) liquid enters through a tube 29 connected to a header 30 and flows successively through coils 31 in chamber e, connectors 32, coils 33 in chamber d and a header 34 to a separator 36. Vapour flows from the separator to a header 38 and thence through superheater coils 39 in chamber c to a header 40. From this header the vapour flows into an axial tube 42 whence it passes through a header 43 and connectors 44 to superheater coils 45 in chamber a. The coils 45 discharge into a header 41 whence a tube 47 conveys the low pressure vapour to the point of use.

Filed: 1976-10-26
Abstract: 1533770 Data processing INTERNATIONAL BUSINESS MACHINES CORP 26 Oct 1976 [12 Dec 1975] 44531/76 Heading G4A In a multiprogrammed system in which time slices are allocated to programs by chained index words, the functions of specified types of instructions in specified programs are varied if certain external and/or internal non-program conditions are satisfied. The index words are held in a store 34, each word comprising a pointer which identifies which of a number of microprograms in a control store 20 is allocated the current time slice and a link address which points to a location in a store 36 holding the address of the next index word in store 34. The number of time slices allocated to any given micro-program by the index words in store 34 may be varied. The pointer from the current word accesses a micro-program pointer from a store 38 and the micro-program pointer in turn accesses the address of the next instruction for the relevant micro-program from a store 32. The current micro-program pointer from store 38 is compared with a set of micro-program identifiers and the OP code of the next microinstruction read from the control store 20 is compared with a set of micro-instruction identifiers. If equality is detected from both comparisons and if predetermined processor internal and/or peripheral external status signals are present a function change control signal on line 11 is produced and modification information pointed to by micro-program (or possibly microinstruction) pointer register 25 is read out from a buffer 29. The decoded modification information may be used, for example, to modify the result from the ALU 51 by +1. The processor also includes a data local store 46 for A and B operands and ALU results. The store 46 may also be used for loading micro-program and micro-instruction identifiers into the comparison registers and modification information into buffer 29 under micro-instruction control. The modification arrangements allow for (micro)programming flexibility without increasing the size of the (micro-)instruction set.

Title: Process for the preparation of alcohol-free alkyl chlorides
IPC: C07C17/38
Filed: 1965-10-21
Abstract: Alcohol-free alkyl chlorides are prepared by counter-currently washing an alcohol-containing alkyl chloride with an aqueous solution of hydrochloric acid having a concentration not above 35% by weight, whereby the alcohol is dissolved in the hydrochloric acid solution and wherein the alcohol contains 1 to 6 carbon atoms.  The alcohol-containing alkyl chloride may be the raw esterification product obtained by the esterification of a C1 to C6 alcohol with hydrochloric acid and any alkyl ether contained in said raw product will also be present in the alcohol-free product.  The solution of alcohol in hydrochloric acid obtained in the process of the invention may be recycled to an alkyl chloride producing step and any hydrochloric acid in the alcohol-free product can be removed by distillation of said product in the presence of water, the acid so obtained being recycled, if desired, to the alkyl chloride preparation.
