Title: Improvements in or relating to processes for the production of pattern effects, moreespecially, relief-like effects, on textile fabrics
IPC: D06Q1/00
Filed: 1950-06-02
Abstract: Relief patterns are produced on textile fabrics by first impregnating, either locally or uniformly, with a precipitating agent for a natural or synthetic resin or components thereof or for rubber latex, synthetic rubber or a cellulose derivative, which latter substance is subsequently applied, together with a dispersing agent, as an aqueous dispersion, the dispersion, containing also pigments and dyes, e.g. substantive and acetate dyes, being applied uniformly or locally, as by printing with deeply-engraved printing rollers, according to whether the precipitating agent is applied locally or uniformly respectively. The precipitated material may be an acrylic or methacrylic resin, a vinyl resin, e.g. polyvinyl chloride, polyvinylidene chloride, polyvinyl butyral and polystyrol, a chlorinated rubber lacquer, nitrocellulose, if desired modified with alkyd or aminoaldehyde ether resins, or acetyl cellulose.  Specified precipitating agents, which are preferably anionic if the dispersing agent is cationic and vice versa, are salts of polyvalent metals, such as aluminium sulphate, chloride and acetate, lead acetate, chromium chloride, iron chloride and sulphate, barium chloride, calcium chloride and zinc chloride and sulphate, as well as alumina, phosphotungstic acid, ferrocyanides, perchloric acid and aromatic sulphonic acids.  Fabrics of vegetable, animal and fully synthetic fibres, e.g. of cotton, regenerated cellulose, cellulose derivatives and superpolyamide fibres may be treated.  To the dispersion fillers, such as flock fibres, metal powders, titanium white and barium sulphate may be added.  The thickness of the deposit may be varied by local variation of the quantity of precipitating agent applied.  The deposits may be grained by boiling in soap/soda solution, and parchmentizing may be effected by treatment with sulphuric acid, followed by mercerizing with caustic soda solution.  Numerous examples are given, in one of which the precipitating agent for a polyacrylic resin dispersion is a cationic condensate from formaldehyde, urea and guanidine. The dispersing agents employed in the examples are oleic acid, triethanolamine, methyl cellulose, carboxymethyl cellulose, morpholine and soap.

Filed: 1948-05-25
Abstract: 649,960. Engine stop-gear. HEIDE, H.C. (Carrier Corporation). May 25, 1948, No. 14170. [Class 122(iv)] In a safety device for a refrigeration compressor 2 failure of lubricating oil pressure actuates a differential pressure mechanism 12 responsive to the difference between the lubricating oil pressure and crankcase pressure to permit electric current to pass through a heater coil 14 of a time delay relay 13 comprising the heater coil 14 and a switch 15, passage of current through the heater coil beyond a predetermined time interval causing actuation of the switch 15 to discontinue operation of the compressor. In operation a starter mechanism 11, to which the safety device is electrically connected, actuates the compressor motor 10, and energizes a transformer 16 and a current flows through the time delay switch 15, heater coil 14 and a differential pressure mechanism operated switch 12. If a predetermined oil pressure is created within a predetermined time interval the differential pressure switch 12 opens thereby preventing further current flow through the heater coil 14, the time delay switch 15 remains closed and operation continues through the circuit closed by switch 15. If the predetermined oil pressure is not created within the time interval or, if during normal running of the compressor the oil pressure falls and remains below the predetermined figure for more than the predetermined time interval, the current flowing through the heater coil 14 causes it to open the switch 15 and thereby open the motor circuit and discontinue operation of the compressor.

Title: Production of moulded articles by the compression of powders, granules, non-flowing doughs and the like
IPC: B30B11/02
Filed: 1952-06-10
Abstract: 722,133. Compression-moulding powder &c. MEYER, M. A. June 3, 1953 [June 10, 1952]. No. 14641/52. Class 87 (2). A press for moulding articles from powder, granules &c. comprises a fixed punch 3 and a movable punch 4 which compress the powder in a die 1 the members being so arranged that, during the working or compression stroke, the die moves in the same direction as, but at a lower speed than, the moving punch 4. The walls of the die diverge upward so that, during compression, a horizontal pressure component is exerted on the powder and the divergence also assists ultimate ejection of the article. The movable punch 4 is attached to a backing plate 6, Fig. 1, which is supported on suspension bolts 11 extending from the die-body 2. The die-body 2 is supported by linkages 15, Fig. 4, which are attached to the fixed top plate 5 carrying fixed punch 3. and to the bottom plate 10 attached to the movable bottom table 12 of the press, and are pivoted to the die-body by pins 18. The lever ratio is such that the die-body 2 moves up at the same time as the press-table 12 but at half the speed of the latter. The die-body in the position shown in Fig. 1 is filled with material 19 and the press closed. In so doing, the die-body 2 is moved upward to meet the top punch 3, carrying with it the bottom punch 4 until the bottom press table plate 10 contacts plate 6, Fig. 2. The compression stroke then begins and punch 4 moves upward at twice the speed of the die-body 2 to compress the material. The press is then opened, an ejecting member 23, Fig. 7 is interposed between the bottom plate 10 and the punch plate 6 and the press again closed sufficiently to eject the pressed article.

Title: Improvements in synchronising systems
IPC: H04L7/00
Filed: 1928-05-19
Abstract: 317,528. Beatty, W. E., (Bell Telephone Laboratories, Inc.). May 19, 1928. Synchronous movements and synchronism indicators.-Correction is initiated by the difference in strength of two impulses. Synchronizing impulses received over a line 14 are so shaped by an impedance 8 and a condenser 9 that, when a driving shaft 4 is in synchronism with a corresponding shaft at the transmitter, an equal portion of each synchronizing- impulse is applied by a distributor brush 3 to a contact connected to a conductor 1 and a contact connected to a conductor 2. If the shaft is not in synchronism the impulse is applied unequally to the contacts with the result that the grids of thermionic valves DT1 and DT2 are unevenly charged by electrons accumulating on the grids through the action of grid condensers 18, 19. The consequent difference in the plate current of the two valves causes a defection of a differential ammeter 34, and also causes windings 25, 26 to produce a differential magnetizing force in a core 28 and hence changes its permeability. This changes the impedance of a winding 29 in the reaction circuit of an oscillating valve DT which drives a phonic motor 5 through an amplifier AT and a relay 43. The inductance 29 with a condenser 39 controls the frequency of the oscillator and the change of inductance produced, as described above, by lack of synchronism alters the frequency of the oscillator to restore synchronism. According to modifications : a short-circuited winding 27 associated with the winding 29 is replaced by a condenser tuning the winding; the phonic motor is driven by a tuning-fork; correction is applied to a differential gear between the phonic motor and the synchronized distributors (Fig. 2, not shown); valves DT1, DT2 are replaced by twoelectrode valves.

Abstract: 550,477. Preparation of high octane gasoline. ANGLO-IRANIAN OIL CO., Ltd., and FAWCETT, E. W. M. Oct. 2,1940, No. 14801. Drawings to Specification. [Class 2 (iii)] Gasoline of high octane number is prepared from normally gaseous hydrocarbons boiling below 50‹C. in a 2-stage process in which a hydrocarbon fraction consisting of one or more normal alkanes is subjected to isomerization at a pressure within the range 1-500 atmospheres and a temperature of 250‹ 600‹C. in the presence of a catalyst comprising a metallic oxide and/or a sulphide of Group III with the possible addition of metallic oxides or sulphides of Group VIII, the isoalkane produced being subjected with an alkane to alkylation under moderately elevated pressure and at a temperature within the range - 50‹ to + 100‹C. in the presence of an alkylation catalyst. In the preferred form of the process the isoalkane is separated from the isomerization product before being passed to the alkylation stage, the unconverted materials being recirculated to the isomerization stage. The alkylation stage is followed by a similar fractionation, the unreacted isoalkane being re-cycled to the alkylation stage. An example is given of the treatment of a natural gas fraction containing n-butane and isobutane. Specifications 548,901 and 550,480 are referred to.
