Title: Improvements relating to the dyeing and similar liquid treatment of textiles and similar materials
Inventor: WALSH JOHN
IPC: D06B3/10
Filed: 1961-09-22
Abstract: 945,421. Treating fabrics. F. SMITH & CO. (WHITWORTH) Ltd. Sept. 13, 1962 [Sept. 22, 1961], Nos. 33949/61 and 36147/61. Heading D1L. In liquid treatment of textile materials, paper &c., said material is caused to travel on a concave supporting belt so as to be carried through a quantity of liquor held at a controlled level in the concavity of the belt and the belt with the material thereon is then caused to pass through the nip of a padding mangle almost immediately after leaving the liquor. In the embodiment shown endless belt 15. is looped around rollers 10 and 14 and is of sufficient length to assume a concave arc at zone 16, being constrained to that formation by roller 17 and by convex lower edges 18 of vertical side walls 19, the latter being adjustable with regard to their distance apart. Liquid is sprayed, via pipe 25, into the concavity formed by the belt and the side walls, to form a pool 26 and the level of this pool can be controlled by any suitable known means. In operation a bath 27 is delivered from endless conveyer 28 on to belt 15 and thence to and through pool 26. As the fluid leaves pool 26 it is taken almost immediately through the nip between rollers 9 and 10 where surplus liquid is expressed and it is then separated from belt 15 in the region of an adjustable doctor 23. Roller 10 is driven through variable gear 12 from motor 13 and the same drive means may be used to drive the input feed belt 28 so that the two speeds can be synchronized. Alternatively there can be separate drive means with suitable synchronizing mechanism incorporated. The belt 15 may also be used to convey the material through further treatment apparatus.

Title: Improved process for the preparation of solutions containing sodium hydroxide
IPC: C01D1/20
Filed: 1946-11-15
Abstract: Solutions containing caustic soda are prepared by reacting hydrated lime with sodium sulphate in a medium of water under such conditions that a double salt, Na2SO4.CaSO4 (Glauberite) is formed, and separating Glauberite together with other solid substances from the resulting solution of caustic soda.  The concentration of sodium sulphate may exceed the minimum concentration at which Glauberite can be stable in the same medium and at the same temperature by at least 10 per cent; and the reaction may be carried out at a temperature much higher than the lowest temperature at which the Glauberite can be stable, and if desired at a temperature at which increased pressure is necessary. Hydrated sodium sulphate may be crystallized from the resulting solution by cooling and further sodium sulphate may be precipitated by the addition of a substance which reduces its solubility in the solution, e.g. ammonia or alcohol.  Sodium sulphate may be recovered from the precipitate formed during the reaction by leaching.  The medium in which the reaction takes place may consist partly in the mother lye from an evaporation plant for salt making. The solutions obtained, preferably after crystallization and removal of hydrated sodium sulphate, may be used directly for the opening of straw, watersoftening or purifying solutions such as brine.  The solutions may also be evaporated to produce concentrated and even solid caustic soda.ALSO:Solutions containing caustic soda, prepared by reacting hydrated lime with sodium sulphate (see Group III), are used for water-softening.  Such a solution, according to one example, contains 25 grams of NaOH and 22 grams of Na2SO4 per litre.

Title: Magnetic core storage apparatus
IPC: G06F3/08
Filed: 1954-11-24
Abstract: 760,562. Electric digital - data - storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 24, 1954 [Nov. 27, 1953], No. 34059/54. Class 106 (1). [Also in Group XVI] Data-storage apparatus, particularly for use in a record-card interpreter, comprises a matrix arrangement of magnetic cores, information being entered into the matrix (from cardsensing means) along the columns and being read out (to control apparatus for printing on the card) column by column successively. The cards shown have 80 columns and upper and lower decks each bearing information in a six-point code. As the card passes downwardly through sensing means, Fig. 3, the rows of either deck (selected by a relay) are sensed successively, and an emitter, Fig. 6, correspondingly selects the rows of a 6 by 80 matrix of magnetic cores. The card then passes to a printing mechanism having two type bars spaced by 40 columns, the cards being stepped laterally while 40 characters are printed successively by each of the two type bars. The type bars are each controlled by six de-coding magnets controlled by the storage matrix. For this purpose, each column of the matrix comprises series connected read-out windings, an emitter pulsing the column circuits successively in pairs spaced by 40 columns. For each group of 40 columns in the matrix, six output tubes 30, Fig. 8, connected to the printing control magnets, are also connected to corresponding row leads 40 to which output windings 24 of the cores are connected through diodes. Diodes are also connected in series with the input coils 12, Fig. 6, of the matrix.

Abstract: 1, 069, 680. Particle size distribution determination. HITACHI SEISAKUSHO KABUSHIKI KAISHA. Aug.21, 1964, No.34264/64. Heading G1A. To determine the particle size distribution of a powder the particles are suspended in a liquid and what is initially a homogeneous suspension 2 placed in a parallel-sided transparent-walled cell 2. At a time t after sedimentation has begun the suspension is scanned in the depth direction by a light source 3 and lens combination producing a thin beam of parallel light which is directed through the sample to photo-detector 4. From the scan is derived a photo-electric output voltage I and at each instant of the scan an equivalent voltage h from potentiometer circuit 5 representing the corresponding depth. The factors I, h and l are fed to computing circuits which determine and plot the particle size distribution curve. A mathematical explanation based on Stoke's Law, of two ways in which the computation may be performed is given.

Abstract: 1,159,061. Treating exhaust gases; spray carburetters. B. WALKER. Aug.3, 1966, No.34748/66. Heading FIB. [Also in Division G1] Exhaust gases are passed through a by-pass 27, Fig. 1, containing an exhaust treating apparatus 28 at idling or deceleration. The exhaust gas flow through the main exhaust pipe 2a and bypass 27 is controlled by valve 20 actuated by a suction operated diaphragm 16 controlled by a valve 14 operated from the throttle linkage. A valve 24 in the by-pass 27 may be linked to the valve 20. During normal running valve 20 is wide open and most of the exhaust gases flow through the main pipe 2a to silencer 5. When the throttle valve is closed lever 10 operates valve 14 to connect intake manifold suction pipe 13 to pipe 15 to operate device 16 to close valve 20 and by-pass the exhaust gases through the treating device 28, which may include a filter, absorbents, chemical agents, or catalysts. The exhaust gases in the by-pass 27 are also cooled by a finned device 26. In Fig. 6 (not shown) the by-passed gases are cooled by an evaporative cooler (36), comprising a cotton wick supplied with water from a device (37b) under the control of a suction operated valve (39) and solids are separated in a centrifugal separator (34) prior to entering the treating device 28. In Fig. 7, the suction in pipe 15 is also transmitted through pipe 75 to a device 73 which actuates a valve 72 controlling an air bleed into the carburetter idling passage 66 to cut off the idling fuel during over-running. The passage 75 is cut off when engine speed drops to idling by a speed-operated valve 75a to avoid stalling. In Fig. 9 a time-delay device 112 is associated with the valve 14 to ensure that opening of the valve 20, Fig. 1, is delayed during opening of the throttle valve. At full throttle a stop 119 on the throttle linkage ensures immediate opening of the valve 20. In Fig. 8 (not shown) a speed responsive device (76) operated from the vehicle speedometer ensures treatment of the exhaust gases in a low speed range as well as at idling.
