Title: Improvements in or relating to reducing the lustre of cellulose-ester or-ether materials
IPC: D06M13/248
Filed: 1932-10-19
Abstract: Cellulose-ester and -ether materials are delustred by subjecting them to the action of hot aqueous media or moist steam in the presence of an amide of a carboxylic or sulphonic acid. Examples of such amides are acetanilide, benzamide, phthalimide, benzanilide, diacetyl-p-phenylenediamine, diacetyl benzidine, oleic amide, stearic amide, p-toluene sulphonamide and its N-methyl or N-ethyl derivatives, xylene monomethyl sulphonamide, and p-toluene-sulpho-benzidine.  The amide may be dissolved in the hot aqueous medium, or dispersed therein by means of soap, turkey red oil, or the dispersing agents described in Specifications 219,349, 224,925, 242,393, 242,711, 269,960, 273,819, 273,820, 322,737, and 323,788, [all in Class 15 (ii)].  The dispersion may be assisted by means of solvents such as xylene or a halogen hydrocarbon. Alternatively, the materials may be first impregnated with the amide, as by padding, using a relatively concentrated dispersion, and thereafter passed through hot or boiling water.  In a modification, the materials are printed with the amides, and then subjected to the action of the hot aqueous media, whereby pattern effects are obtained.  If desired, the delustring baths may contain substances adapted to modify the action of the bath, as described, for example, in Specification 260,312, [Class 2 (ii)].  A further application is for the removal of " glaze marks " (e.g. marks produced by improper ironing) from cellulose acetate fabrics, without substantial delustring of the material taking place.  The following examples are given: (1) Cellulose acetate fabric is treated in a jig with a hot dispersion of p-toluene sulphonamide.  (2) A cellulose acetate garment containing " glaze marks " is treated in a hot bath comprising a dispersion of p-toluene sulphonamide.  (3) Cellulose acetate fabric is either treated with a hot dispersion of acetanilide, or is padded with a more concentrated dispersion of acetanilide, allowed to stand, and thereafter passed through a tank of boiling water.  Specifications 165,164, 266,777, [both in Class 2 (ii)], and 409,276 also are referred to.

Title: Process for the preparation of new crystalline glucosides from digitalis
Filed: 1931-10-21
Abstract: The glucoside preparation obtained from digitalis lanata by the process described in the parent Specification is separated into three isomorphous crystalline glucosides by means of a fractionating operation wherein it is dissolved in an organic solvent non-miscible with water together with an organic solvent miscible with water, the layers formed being separated after addition of water, and the operation repeated with each of these layers until the properties of the glucosides contained therein undergo no further change and give distinct colorations by Keller's reaction.  Suitable solvents non-miscible with water are chloroform and ethyl acetate, and as solvents miscible with water methanol, ethanol, or acetone may be employed.  When a solution of the original glucoside preparation in a mixture of chloroform and methanol is shaken with water, three layers are formed, the lower chloroform layer containing chiefly the glucoside A, the middle undissolved layer glucoside B, and the upper aqueous methanol layer glucoside C.  Each of the separated layers is separated and treated as before until sufficiently purified.  The first treatment may also be carried out with ethyl acetate instead of chloroform, the acetate solution containing only glucoside A, while the aqueous methanol layer contains chiefly glucosides B and C, and is extracted with chloroform until freed from glucosides A and B, the extracts being further fractionated by means of ethyl acetate.  Other combinations of solvents may be employed. Examples are given, and the properties of the three glucosides are described in detail.

A shoot 3, Fig. 4, for feeding electric lamp caps is tiltable about an axis A between a horizontal position in which a row of caps are taken up by the shoot and an inclined position in which the taken-up caps move down the shoot. The capsupporting portion of the shoot consists of rails 24, Fig. 5, attached to toggle levers 25 which are operable to vary the rail separation between an open position preparatory to taking up a row of caps and the position shown, in which the rails support the taken-up caps. Feed to shoot.-Fig. 1 shows a magazine 1 in which a stack of trays 2, each loaded with caps, is lowerable and the lowermost tray movable step-by-step horizontally. At each step of such horizontal movement the shoot 3 is operated to take up a row of caps from the projecting portion of the lowermost tray, and the shoot is then tipped about its axis A. When empty, this tray is taken by support 4, which is then lowered by one tray depth-by mechanism 6 actuated by microswitch 5. The next tray is then lowered by a combination of tilting, raising and lowering movement of tray-engaging levers 7, Fig. 3. Discharge from shoot.-Each row of caps fed to the shoot 3 passes by gravity to its lower end and thence on to fixed inclined rails 23<SP>1</SP> from which the caps are dispensed singly by the two-pronged rocking lever of Fig. 8, in which the two prongs 29 intersect the path of the caps in alternation and at locations separated by one cap diameter. Control system.-The presence of caps on the fixed rails 23<SP>1</SP> is sensed by a rockable feeler 33 which is urged towards the caps by a spring- loaded lever 37 every time the operating shaft 30 of the prongs 29 is rocked. When the absence of a cap is detected by the feeler 33 it actuates a microswitch 35 to cause the empty tilting shoot 3 to return to the horizontal and take up a further row of caps from the magazine, which is itself suitably actuated at the same time.

Abstract: 1,268,711. Alkylation of aromatic compounds. CANADIAN PATENTS & DEVELOPMENT Ltd. 10 June, 1969 [12 June, 1968], No. 29294/69. Heading C2C. [Also in Divisions C1 and C5] Alkylation, i.e. introduction of a substituted or unsubstituted alkyl or cycloalkyl group, of ring carbon atoms of an alkylatable aromatic compound is effected by reacting the aromatic compound with an aldehyde or ketone, or a compound generating an aldehyde or ketone under the reaction conditions, in the presence of a strong inorganic acid condensing agent and a reducing agent, the aromatic compound and the aldehyde or ketone being stable under the reaction conditions and the aromatic compound having at least one ring carbon atom bearing replaceable hydrogen or a substituent removable under the reaction conditions to yield a replaceable hydrogen atom, to form an intermediate which is reduced to the alkylated aromatic compound. Specified aromatic compounds are pyrrole and benzene and derivatives thereof. Specified aldehydes and ketones are aliphatic compounds which may be substituted by carboxy, carbalkoxy, aryl, amino, acyl, hydroxy and halo groups. Preferred reactants are formaldehyde and acetaldehyde which yield methylated and ethylated products and are used in the form of paraformaldehyde and paraldehyde. The ketone reactant may form part of the aromatic compound and alkylation proceeding with intramolecular ring closure. Specified acid condensing agents are HI, HBr, HCl and H 2 SO 4 . Reducing agents include HI solutions, Zn, Zn amalgam and stannous bromide or chloride. It is preferred to use HI in a dual role, especially in association with red phosphorus, phosphonium iodide or hypophosphorus which regenerates HI from by-product iodine. The reaction may be conducted at normal or elevated temperatures in the presence of a solvent, e.g., acetic acid. Alkylation normally proceeds to the peralkylated product. Examples describe the preparation pentamethylphenol and a wide variety of alkylated pyrroles, including carbalkoxy and acetyl derivatives thereof.
