Abstract: 524,737. Waterproofing textiles: SOC. OF CHEMICAL INDUSTRY IN BASLE. Nov. 3, 1938, Nos. 5606/40, 5607/40, 5608/40 and 5609/40. Convention dates, Nov. 5, 1937, Jan. 4, 1938, Feb. 3, 1938 and Oct. 14, 1938. Divided out of 523,396. [Class 140] [Also in Groups IV and III] An N-methylol or N-chlormethyl compound of a carboxylic acid amide is condensed with a carboxylic acid halide, anhydride or salt. In a modification, a carboxylic acid amide is condensed with a halogenmethylether of an alcohol. When the starting materials and products do not contain a water-solubilizing group viz, a sulphonic, sulphuric acid ester or thiosulphuric acid ester group, an onium group, or an amino, imino or residue containing an amino or imino group (in salt form) a halogen atom or a hydroxy group must be present and the halogen atom is replaced by a thiosulphuric acid ester group, an onium group or an amino, imino or residue containing an amino or imino group (in salt form) or the hydroxy group is sulphonated. The watersolubilizing group is so situated in the molecule that there are at least two carbon atoms between the water-solubilizing group and the nitrogen of the amide group or the oxygen of the ester or ether group. Products containing an aliphatic or cycloaliphatic residue of high molecular weight form salts which are decomposed by heating or saponifying, insoluble products being formed. By decomposing the salts on textiles the latter are rendered waterproof. The products may be used in association with sodium acetate or other salts, solvents, soaps, colloids and loading, softening and wetting agents. In an example stearic acid methylolamide is condensed with benzoic acid sulphorchloride in pyridine; the product dissolved in formic acid may be used for treating textiles ; cotton &c. after treatment, drying and ironing becomes water repellant; salts, e.g., aluminium formate or magnesium sulphate, starch or paraffin may be added to the treating liquor.

IPC: G05D13/10
Filed: 1920-02-25
Abstract: 164,090. Eastwood, W. Feb. 25, 1920. Dash-pots. - In apparatus for stabilizing governors as described in Specification 23217/12, the dash-pot cylinder a, the spindle on which slides the floating piston b, and the bearing plate or plates for the equalizing spring or springs, or some of such parts, have permissible movement such as will enable them to take up the requisite relative positions to compensate for inaccuracies of alignment. In one form, the cylinder a is pivoted on a pin h mounted in a ring i carrying external pins journaled in an outer ring k connected by rods l to the governor. The spindle e is universally jointed to the abutment o of the spring c and to a rod m connected to a fixed casing f. The peripheries of the spring abutments o, o<1> are rounded and out of contact with the casing. In another form the piston b has permissible movement about a spherical enlargement slidable in the spindle e, which is directly connected to the casing f, and the plates o, o<1> can tilt about spherical enlargements on the spindle e. In the form shown in Fig. 3 the piston slides on the spindle e, and the upper end of the spindle has a gimbal or like mounting. In another form, applicable to a shaft governor and comprising two coaxial dash-pot cylinders, the spindle common to the two dash-pots has a transverse bore in which slides a block carrying a pin, which is fixed in a hole in the governor shaft. In another form one of the plates o, o<1> is connected by a gimbal ring &c., to the casing f, and the other is connected by a gimbal ring &c. to the piston. In another form. one end of the spring bears on a fixed plate on a cylinder f and the other end is fixed to the centre of the piston. In another form, the gimbal mounting for the lower end of the cylinder is dispensed with, and the rod l is thinned or flattened in two directions at right-angles to each other.

Abstract: 881,945. Printing on ceramic ware. SERVICE (ENGINEERS) Ltd. Feb. 20, 1958 [Feb. 20, 1957], No. 5670/57. Class 100(2) An offset printing apparatus, particularly for printing on ceramic ware, comprises an offset member 14 having two opposed deformable pads 16, 18 thereon which are joined together by rods slidable in holes in a shaft 8, and a flat circular plate 50 carrying two or more engraved designs thereon, whereby the member 14 may be depressed against the action of springs to enable the bottom pad to engage one of the designs on the plate 50. The plate 50 is connected by gearing 52, 54, 56, 60, 48 to the shaft 8, and the shaft 8 is adapted to be driven through a slip clutch comprising a disc 36 fixed to the shaft, and a power-driven disc 40 on a sleeve which is rotatable on the shaft. The disc 36 has notches in its periphery adapted to be engaged by one end of a latch 66 pivoted on the frame at 68: the other end of the latch has a spring-retained pawl 76 pivoted thereon which co-operates with abutments 32, 34 on the offset pads. Inking means (not shown) applies ink to the designs on the plate 50. In operation, assuming the top pad 16 has picked up an inked impression from the plate 50, an article to be decorated is pressed on to the pad 16. This printing operation causes the pad 18 to descend and contact an inked design on the plate 50, the abutment 34 on that pad flicking past the pawl 76 and not disturbing the latch 66. On removal of the decorated article, the member 14 moves upwardly, the abutment 34 trips the latch 66, the shaft 8 is rotated through an angle of 180 degrees, determined by an opposed notch on the disc 36, in which case the pad 18 is not uppermost. A device for presenting plate blanks to the offset pads comprises a ring-shaped support of rubber mounted on slides, the plate and support being urged downwardly by an elastic pad against the action of springs. The elastic pad may be pneumatically operated. Specification 763,572 is referred to.

Fig. 4 shows a trefoil structural arrangement of the coils L1, L3, L4, mounted on a carrier or casing b provided with a plug connection h. One end of each coil is taken to the common junction m and the other ends are led respectively to the earth-plug e<1>, the grid socket g<1>, and the aerial terminal a<1>. The three coils may be wound jointly as a continuous single or multi-layer coil, either in cylindrical, slab, or air-spaced form. Fig. 5 shows such a coil diagrammatically, the continuous winding being cut at the dotted lines z, and re-connected as shown. The coil L4 comprises two adjacent sections in inductive opposition, while the coil L3 has means d for short-circuiting some of its turns adjacent the coil L4.
