Title: Improvements in the treatment of cellulosic textile materials
IPC: D06P5/12
Filed: 1935-01-17
Abstract: Pattern effects are obtained upon a textile material by locally impregnating it with a synthetic resin produced by reaction on the material between an aliphatic or aromatic amine or amide or derivative thereof (other than a partial condensation product with an aldehyde) and an aldehyde applied thereto together or separately and applying a dyestuff locally or otherwise after the application of such reagents.  The dyestuff may have affinity for either the impregnated or non-impregnated material.  Specified amines, amides and derivatives thereof are urea, thiourea, guanidine, dicyandiamide, aniline, methylaniline, diphenylamine, benzylaniline, b -naphthylamine and aromatic sulphonamides, e.g. p-toluenesulphonamide and their N-alkyl derivatives and specified aldehydes are formaldehyde, acetaldehyde and benzaldehyde.  The textile materials may be of cellulosic fibres, e.g. cotton, linen, jute, ramie or artificial silks of the viscose, cuprammonium or nitrocellulose types or may be of cellulose esters or ethers or of natural silk or other animal fibres.  The following examples are specified.  (1) A fibre or fabric of cellulose or cellulose derivative is printed or otherwise locally impregnated with a mixture of thiourea, formaldehyde, formic acid and water, dried for 1--2 hours at 80 DEG  C. until a condensation product insoluble in boiling water is formed, and, in the case of a cellulosic material, dyed with a direct dyestuff with addition to the bath of the usual assistants, e.g. sodium sulphate or a wetting agent such as a sulphonated higher fatty alcohol; the untreated areas are coloured, while the treated areas remain white; in the case of either a cellulosic or a cellulose derivative material, if an acid dyestuff without affinity for cotton is used, the treated areas are coloured, while the untreated areas remain white and if a basic dyestuff is used the treated areas are more deeply coloured than the untreated areas; plasticizers or softeners such as glycerine, oils or sulphonated fatty oils may be present in the resin-forming mixture, also latex or other agent for increasing the fixation.  (2) A similar fibre or fabric is printed or otherwise locally impregnated with a mixture of dicyandiamide, ammonium sulphocyanide and 40 per cent formaldehyde and dyed as in (1).  (3) A similar fibre or fabric is printed or otherwise locally impregnated with a mixture of urea, dicyandiamide, glycerine, an alkaline or alkaline earth sulphocyanide and 40 per cent formaldehyde and dyed as in (1).  Further effects are obtainable if the fabrics contain also silk, wool, or other animal fibres.  Lists are given of suitable direct, acid and basic dyestuffs.  According to the Provisional Specification the aldehydes may be replaced by ketones.

Title: Thermally sensitive capacitive circuit element
IPC: G05D23/20
Filed: 1962-03-20
Abstract: 998, 534. Measuring temperature electrically. INTRON INTERNATIONAL Inc. March 20, 1962 [March 27, 1961], No. 10599/62. Heading G1N. [Also in Divisions G3 and H1] A positive temperature coefficient capacitor with a polyvinyl fluoride dielectric is used in measuring temperature and controlling in accordance with changes in temperature. Its response rate is determined by mounting it in a housing of predetermined heat capacity or in association with a slug of high heat capacity e.g. of lead. In a circuit providing remote indications of temperature the frequency of a Hartley oscillator is determined by such a capacitor in its resonant circuit. The variable frequency signal is transmitted to a remote station where it is converted to a visual indication. Alternatively, the transmitter comprises a two stage transistor-oscillator (Fig. 12) including a Wien bridge including temperature sensitive capacitors 1300<SP>1</SP> and 1300<SP>11</SP> in parallel arms with ganged frequencyselector resistors 1335<SP>1</SP>, 1335<SP>11</SP> and amplitude controlling rheostat 1380. In another system for setting off an alarm or e.g. throttling a fuel supply in response to an abnormal temperature condition at a remote station a control signal of variable frequency is transmitted to a parallel resonant circuit including the temperature sensitive capacitor at the station. The threshold temperature at which a relay connected across the circuit is tripped is thus determined by the frequency of the control signal. In another arrangement the capacitor is used (Fig. 6) to switch off electric motor 720 if it overheats. The output of bridge 733 is fed via transistor amplifier 737 to a phase comparator 740 the output of which operates relay 732 when the motor temperature exceeds a preset level. In an alarm system (Fig. 8 not shown), the capacitor forms part of a series resonant circuit controlling the firing point of a controlled rectifier in the alarm circuit while in another arrangement (Fig.9,not shown),for switching off the electroplating current when the electrolyte temperature falls too low it is in a parallel resonant circuit controlling the voltage across a relay.

Abstract: 746,100. Stencilling apparatus. VALIELA, J. Jan. 21, 1954, No. 1871/54. Class 100 (2). In a machine for printing an article having non-planar surfaces by applying the design by a silk-screen stencil to an elastic offset diaphragm which is then pressed on to the article by fluid pressure, the diaphragm-carrying section of the machine table is hinged to the recessed article-supporting section, e.g. as described in Specification 646,394, but the stencil frame is slidable along the table to and from a position over the diaphragm. Two stencil frames sliding in directions at right angles to each other may be used with a single diaphragm for two-colour printing. In Fig. 1 the stencil frame 13 is fixed by bolts and wing-nuts to a metal or other frame 14 slidable by handles 16 along guide grooves 20 in the top of the table 11, from the inoperative position shown to its printing position in which an adjustable bolt 22 contacts a fixed stop 23; a squeegee with two handles 18 is provided. The rubber &c. offset diaphragm 25 is stretched over a circular foraminate plate 26 by a clamping ring 33, the plate forming one surface of a hollow metal block 27 hinged at 40 to the table 11 so that the diaphragm 25 may be turned over the article 60 to be printed, and then forced into contact therewith by compressed air admitted through a conduit 31 to the interior of the block 27, the latter being isolated by a cross-tube 38 from a light floating tube 36 open to atmosphere and leading to a small reinforced opening 35 in the diaphragm 25, whereby air trapped between the diaphragm and the article 60 may escape, and whereby after printing air may re-enter to allow the diaphragm to retract. The ceramic article 60, such as a plate, is supported by an exchangeable frame 51 having an inclined part 52 and a cylindrical part 53 containing an adjustable platform 55; to centre the plate three sliding radial fingers spaced at 120 degrees around the outer part of the frame 51 are simultaneously moved inwards against the rim of the plate by a handle 70 which rotates a spring- biased ring 63 having cam channels engaged by pins on the radial fingers; for small plates an inner ring 71 may be inserted to provide extended support slots for the radial fingers. The lock to hold the diaphragm block 27 in position during printing, consisting of a roller 76 and handle 77 at the top of a rotatable post 75, may be coupled to a control valve 79 which connects a conduit 82, leading to the conduit 31, either to a source of compressed air at 81 or to atmosphere. Fig. 4 shows an ejector for lifting the printed plate 60 to facilitate removal by hand: a rod 65 is projected through an opening in the inclined part 52 of the frame 51 by a spring- loaded plunger 91 carrying a sliding block 87 to which the rod 86 is pivoted.

Abstract: 478,771. Spray carburetters. STEWART-WARNER CORPORATION. Jan. 23, 1937, No. 2041. Convention date, Jan. 28, 1936. [Class 7 (iii)] [Also in Groups XI and XIII] Fuel is supplied to the carburetter of an automobile heater from the float chamber 104 of the engine carburetter. The chamber 104 is connected by a T-piece 116 directly to the carburetter and to a chamber 122 which before use becomes full of fuel. The limb of the T-piece connected to the chamber 104 contains filters and a very constricted passageway, and the end of the T-piece connected to the chamber 122 contains a passageway 132 constricted but considerably larger than the other constriction. A tube 128 extends into the chamber 122, and contains a small opening 130. When the valve 238 is opened, owing to the relative sizes of the constrictions, more fuel is drawn from the chamber 122 into the carburetter than from the float chamber 104. The level of the fuel in the chamber 122 falls until fuel is drawn from the chamber 122 only through the opening 130 and finally, when the chamber 172 is heated up, the fuel is drawn only from the float chamber 104, and is mixed with air coming from the chamber 122. In the carburetter, the fuel passes through openings 150 into a Venturi-tube 142 into which air passes through the screen 146 and throat 144. Further air is admitted .through openings 152. A shield 154 is provided.

Abstract: 178,538. Pfeiffer, A. F. Jan. 15, 1921. Spray carburettors.-A number of air inlets 3, 5, 6, some of which are provided with fuelnozzles 7, 9, are arranged around a casing 1 containing a ported valve 13 capable of axial movement by a rod 15 and of rotary movement by an arm 26, strap 18, projection 19, and groove 21. The valve has ports such as 23, 25 to bring the air inlets into action successively as the valve is raised, and a port 22 for co-operation with the inlet 6. At any axial position of the valve, rotation from some standard position in one direction opens the air inlets, such as 6, which have no nozzles, without reducing the areas of the inlets 3, 5, which may be already open. This weakens the mixture, or, if the valve is in its lowest position, admits air only. Rotation in the opposite direction reduces the areas of the inlets 3, 5 whilst keeping the inlet 6 closed, thus giving a richer mixture. One side of the port 22 may be inclined as shown at 29. The mixing chamber may be heated by a jacket 28. The nozzles are fed from an annular fuel chamber supplied through a conduit 10 and in which plugs 11, 12 are provided to gain access to the nozzles, which are placed near the valve opening to be at the point of highest air velocity.
