Title: Process for the improvement of dyeings on cellulosic fibres with substantive dyestuffs
IPC: C09B39/00
Filed: 1934-08-02
Abstract: Azo dyes, forming on the material; printing.--Dyeing on cellulosic fibres with azo dyestuffs of the general formula R[--NH--CO--R<1>--N = N--Py]n wherein R represents the residue of an aromatic amine or of an aminoazo compound not containing the residue Py, R<1> represents a residue of the benzene series, Py represents the residue of a 1-aminoaryl - 5 - pyrazolone - 3 - carboxylic acid (or ester) coupling component, and n is 1 or 2, the whole dyestuff being so constituted that only the aminoarylpyrazolone residue is capable of further coupling with a diazo component, are after-treated with a diazotized base free from water-solubilizing groups, e.g. diazotized m- or p-nitraniline or 4- or 5-nitro-2-anisidine, to improve the fastness to washing.  Compared with the dyeings similarly produced from the dyestuffs specifically referred to in Specifications 14315/09 and 7303/13, [both in Class 2(iii)] the resulting dyeings are of an improved dischargeability to a pure white.  The following examples are specified: (1) Cotton, dyed from a Glauber's salt-soda bath with the reduced dyestuff from tetrazotized di - (4<11> - aminobenzoyl) - 4 : 4<1> - diaminodiphenylurea - 3 : 3<1> - disulphonic acid (1 mol.) and 1-(3<1>-nitro)phenyl-5-pyrazolone-3-carboxylic acid (2 mols.), is after-treated with diazotized p-nitraniline to obtain a dyeing of good fastness to light and dischargeable to a pure white.  (2) Cotton, similarly dyed with the dyestuff obtainable by reducing the nitro group of p-nitrobenzoyl-p-phenylene diamine --> 1-phenyl-5-pyrazolone-3-carboxylic acid, diazotizing, coupling with 1 - (m-nitro)phenyl - 5 - pyrazolone - 3 - carboxylic acid and reducing the nitro group, is after-treated with diazotized p-nitraniline.  (3) Cotton, similarly dyed with the dyestuff obtainable by saponifying the acetylamino group of acetyl - p - phenylenediamine --> salicylic acid, condensing with p-nitrobenzoyl chloride, reducing the nitro group, diazotizing and coupling with 1 - (m - or p - amino)phenyl - 5 - pyrazolone - 3 - carboxylic acid, is after-treated with diazotized p-nitraniline or 4- or 5-nitro-2-anisidine.  (4) Cotton, similarly dyed with the dyestuff, 2-aminobenzoic acid --> (alkaline) p - aminobenzoyl - 2 - amino - 5 - naphthol - 7 - sulphonic acid --> 1-(m-amino)phenyl-5-pyrazolone-3-carboxylic acid, is after-treated with diazotized p-nitraniline.  (5) Cotton, similarly dyed with the dyestuff, m-aminobenzoyldehydrothiotoluidinesulphonic acid --> 1-(m-amino)phenyl - 5 - pyrazolone - 3 - carboxylic acid, is similarly after-treated.

Title: Improvements in or relating to stabilizing arrangements
IPC: G01C9/12
Filed: 1954-08-04
Abstract: 760,866. Clinometers. SUREL, H. J. Aug. 4, 1954, No. 22645/54. Class 97(2) A pendulum-type clinometer similar in construction to that in Specification 712,504 has ratchet and pawl means which operate to lock the pendulum if the latter undergoes excess swinging dueto sudden changes in the inclination of the apparatus. The pendulum weight 62 is mounted on the hub 60 to rotate about the collar 58. It carries a small pendulum weight 76 on the arm 75 pivoted at 74. The pendulum weight 62 has an internal part-cylindrical surface 86 over which a trolley 87 can run. The pendulum 76 and trolley 87 are urged towards their mean positions with respect to pendulum weight 62 by springs 78 and 95 respectively. Any sudden rotational movement of the apparatus causes one of the pairs of contacts 83a, 83b and/or one of the pairs of contacts 94a, 94b to make. Contacts 83a and 94a are arranged to energize solenoid 101a to cause its associated pawl 120 to engage ratchet teeth 100 on the pendulum weight 62, while engagement of contacts 83b or 94b energizes solenoid 101b and operates the other pawl 120. By this means, pendulum weight 62 is prevented from excess swinging. As in Specification 712,504, the pendulum 62 is connected by link 65 to a member 51 which is freely rotatable on bearing 15 and carries rotatable planet gear wheels 56, mounted on pins 55. These wheels engage a fixed internally-toothed gear ring 43 and also an internally-threaded gear 47. The internal threads of the latter engage the threaded portion 46 of a spindle 14 which is slidable in its bearings but cannot rotate due to the pin 44. The apparatus is bolted by the bosses 123 to a vertical surface whose inclinations are to be measured, and any angular rotation in a vertical plane results in relative movement of pendulum 62, which movement is transmitted via link 65 and planet wheels 56 to gear 47 which causes axial movement of spindle 14. The latter is coupled at 70 to spindle 19 and axial movement of the latter causes it to rotate also, due to its helical groove 20 engaging the pin 21. The apparatus is so constructed that this rotation is equal and opposite to the rotation of the apparatus with respect to pendulum 62 so that the end platform 34 of the spindle 19 will always remain horizontal. The platform 34 supports a wheel 33 attached to the indicating arm 31, which is also connected via plate 30 and link 38 to a second pendulum 28. Both pendulum 28 and plate 30 rotate together about bearing 22 and thus maintain the indicator 32 vertical. The indicator 32 then indicates the inclination of the apparatus on a scale 35 fixed to the casing. Specification 692,342 also is referred to.

Abstract: 933,853. Rolling. ENGLISH ELECTRIC CO. Ltd. Oct. 6, 1959 [July 15, 1958], No. 22669/58. Class 83 (4). In an electric control system for a strip rolling mill 10, a gauge 16 or 17 produces an electric signal dependent on the thickness of the strip passing into the mill, a potentiometer 25 provides an adjustable thickness reference signal, and an amplifier 22 with a control winding 22a responsive only to an excess of the thickness signal over the reference signal, energizes a coil 28a of a relay 28 so that the mill is stopped to prevent strip of excess thickness entering the mill. Strip 11 is fed back and forth through the mill by coilers 12, 13 which are also controlled by the relay 28 the thickness signal being produced by the gauge 16 or by the gauge 17 according to the direction of movement of the strip. At the end of each pass the mill is stopped by the excess thickness of the part of the strip retained on the coilers.

Abstract: 747,572. Forging; extruding. BOSCH GES., R. Aug. 19, 1953 [Sept. 30, 1952], No. 22825/53. Classes 83 (2) and 83 (4). A hollow member with stepped walls, more particularly a sparking plug casing 17, is produced by pressing a hollow cylindrical blank, having a conical bore, in a die 13, Fig. 4, by means of a ram 15 to cause an enlarged head to be formed at one end by combined backward extrusion and radial spreading without endwise restraint. Simultaneously the forward end of the blank is extruded between an extension 16 of the ram and the die. The enlarged head is of hexagonal shape. An ejector plunger 18 removes the casing from the die. A solid cylindrical blank of 0.1 per cent carbon steel which has been annealed is first inserted in a die 2, Fig. 2, and pierced by a conical ram 3. A recess 6 is formed on the blank by a ram 7 which also ejects the blank from the die. The remaining core 12 of the blank is then removed by a further punch and die to form the blank 11, Fig. 3 (not shown). The casing 17, produced in the die 13, is annealed and is then " sized " in a die 19, Fig. 5. This operation produces end lips 22, 23 which are eventually removed by machining. All of the pressing operations and the shearing of the initial solid blank from a length of rod may be performed in a multipledie press.

Title: A method of preparing quick-cooking and non-glutinous cereals
Inventor: RUTGERS REIJER
IPC: A23L7/196
Filed: 1955-08-09
Abstract: In a method of preparing quick-cooking cereals, e.g. from rice or groats, the grains, unhusked if necessary, are cooked with a moderate amount of water at a temperature up to 130 DEG C. preferably under a superatmospheric pressure up to 2 atmospheres, until they have a final moisture content of at most 60 per cent., and are dried in two stages, viz., a rapid drying above 130 DEG C. to form porous grains, and an after-drying below 130 DEG C.  The cooking, which substantially gelatinizes the grains, is such that a loose granular mass is obtained, e.g. by keeping the mass in movement and by supplying steam directly only in the later cooking stage. Drying is by means of a hot gas, such as air, in a drum drier, or the grains may be dried in vacuo.  A thin coating of starch or talc applied to the grains on drying separates them from each other and from the wall of the drying vessel.  The grains may be weakly crushed, preferably after the cooking, without causing the formation of flakes; if crushed prior to cooking the grains are soaked in water below 50 DEG C. until 30-50 per cent. of water is absorbed, they are then slightly crushed, cooked with a small amount of added water and with steam and dried in two stages as described above.  Tempering treatments may be applied to the grains at any stage of the process to prevent the grains from caking together.  The colour of the final product may be improved by cooking in the presence of a little acid, e.g. hydrochloric, sulphuric, tartaric or citric acid, or vitamin C. Flavourings such as sugar solution and/or malt extract may be added. Salt, minerals and vitamins as nutritives can also be added.
