Title: Improvements in or relating to the treatment of fibrous textile materials
IPC: D06M13/188
Filed: 1938-06-15
Abstract: 515,908. Waterproofing textiles ; estertfication processes. DEUTSCHE HYDRIERWERKE AKT.-GES. June 15, 1938, No., 17840. Convention date, June 15, 1937. [Class 2(ii)] [Also in Group VIII] Fibrous textile materials of animal, vegetable or artificial origin are subjected to surface treatment in a bath containing one or more high molecular fatty or wax acids, e.g., palmitic, stearic or montanic acid, and one or more anhydrides of non-soap-forming organic acids. Suitable anhydrides are those of chloracetic acid, bromacetic acid, cyanacetic acid and benzoic acid, and the mixed anhydride of benzoic acid and aliphatic acid. A solvent such as benzine, carbon tetrachloride or benzene is present, and if desired also small quantities of free acid or organic base, particularly a tertiary amine. The anhydride may also be applied in aqueous emulsion. In an example, artificial silk satin is treated in a bath consisting of a solution of 1 per cent. each of montanic acid and chloracetic anhydride in benzene. In another example, cotton material is treated in a bath containing 10 parts stearic acid, 9 parts bromacetic anhydride and 1 part bromacetic acid in 1,000 parts of benzine.

A mine roof anchor bolt comprises a rod 12, screw-threaded at one end, an expandible shell divided into a plurality of segments 15 of arcuate cross-section having ridges 16 on their outer surfaces, the cross-section of each ridge being substantially an isosceles triangle, and butting at ends 25 on a support 22, each segment having a number of different thicknesses A 1 , A 2 , A 3  measured at locations between adjacent ridges, which become progressively greater proceeding away from the tip of the one end, and being formed with a slot 19 extending from the end adjacent the tip to almost the other end of the segment, a frusto-conical expander member 14 of circular cross-section with a screwthreaded bore corresponding to the rod, having ribs 18 to locate in the slots 19 and prevent relative turning as it is drawn into the shell by the rod 12 to expand to segments. The segments are made from malleable cast metal, with rounded corners at 24, and are bound together by a plastics sleeve 23. The inner surfaces of the segments correspond to the external surface of the expander, except that they have an angle of 5 degrees, which is about 2 degrees less than that of the expander, to reduce friction.

Abstract: 1393787 Asbestos-cement pipes; coating EVERITUBE 18 April 1972 [21 April 1971] 17946/72 Heading F2P [Also in Division B2] A method of producing asbestos-cement products e.g. pipes, comprises after forming the products applying on all the faces of the product a waterproof coating at a moment before the end of hardening and after the start of setting, as soon as the products have a dimensional stability sufficient to permit handling and so long as the amount of water contained in the products permits optimum hydration of the products. As shown pipes are formed on a mandrel at 1, passed into a hardening stove 2, immersed in a tank of water 3, cut and machined at 4, 5 and fed to coating station 6. The coating is applied as soon as any surface water has evaporated. For applying the coating e.g. bitumen, coal tar or pitch, the tube T<SP>1</SP> is supported on rollers 8 at coating station 6 which consists of a carriage 10 mounted for reciprocating motion and having tubes 11, 12 extending therefrom and having at their ends nozzles 15. The tubes 11, 12 communicate with reservoirs 16, 17 in the carriage, the reservoirs being fed by conduits 18, 19 connected by flexible conduit 20 to a fixed tank 21 maintained under gaseous pressure. The tube is rotated on rollers 8 and the carriage reciprocated to apply coating material to the inside and outside surfaces of the tube.

Title: Improvements relating to cooking stoves
Inventor: HICKS ANTHONY MICHAEL
IPC: F24C15/10
Filed: 1957-06-07
Abstract: 871,371. Electric cooking stoves; grease guards. SIMPLEX ELECTRIC CO. Ltd. June 9, 1958 [June 7, 1957], No. 18125/57. Classes 39(3) and 126. In a cooking stove having one or more hot plate units 14 associated with a hob plate 13, the or each hot plate unit is constructed to discharge spillage peripherally on to the hob plate and the hob plate has a depressed area 36 which surrounds the hot plate unit or units 14, in the latter case being common to at least some of the units, is of sufficient dimensions to afford access for the mopping up of spillage and has no outlet for spillage except over its outer boundary. The area 36 is defined by ribs 37-42, a lower rib 37 being at any accessible side of the stove. The hob plate 13 may continue substantially imperforate beneath the units 14, reinforced by ribs 49, and is formed with upstanding ribs 43, Fig. 2, surrounding the area underlying the units. Alternatively, there may be an aperture (not shown) beneath each unit defined by an upstanding flange similar to the outer wall 51 of the ribs 43 and spanned by a beam. The or each unit is rendered impermeable to spillage by the incorporation of either an imperforate body plate 30, Fig. 6, or a barrier plate 19, Fig. 2, in association with a sheathed electric element 18, the unit having a peripheral flange such as 34 or 20 which overlaps the rib 43 or flange 51. Each unit carries a headed stud 21 which passes through a hole 45 in the hob plate and a slot in a bowed metal strip 55, a neck 23 on the stud engaging the edges of the slot to retain the unit in position. In the embodiment shown in Fig. 2, the element 18 may be supported by a plate 25 with a dark upper surface bearing ribs which contact the coils of the element or by a spider of open form, in which case the plate 19 has a bright upper surface. Holes are formed in the plate 19 to receive the ends 27 of the element 18, the flanges 29 formed by plunging the holes being sealed to the sheath of the element by brazing. If both the plate 25 and the spider are omitted, the plate 19 may carry ribs and have a turret portion, to receive the ends of the element 18, which is rotatable relative to the rest of the plate 19 and sealed thereto so that the element 18 can be swung aside in its own plane. In the embodiment shown in Fig. 6, the body plate 30 has grooves housing heating elements 32 and the flange 34 is secured as an insert during casting of the plate. Alternatively, the flange may be integral with the plate or may be welded to or pressed into engagement as an interference fit with the outwardly directed face of the plate 30. Specification 871,372 is referred to.

Title: Improvements in and relating to the manufacture and production of delustred rayon
IPC: D01F2/08
Filed: 1932-06-29
Abstract: The lustre of artificial silk is reduced by incorporating in the spinning solution a chlorinated diphenyl.  In the case of viscose or cuprammonia solutions, a solid chlorinated diphenyl may be ground and introduced directly into the solution, or may be dissolved in a suitable solvent and then mixed with the spinning solution, preferably together with an emulsifying agent, e.g. p  Twitchell's reagent.  As solvent there may be used a volatile material which is subsequently removed by evaporation, for example isopropyl ether, or a non-volatile solvent which is immiscible with the alkaline spinning solution but is extracted by the coagulating or other bath, for example dimethyl aniline.  The lower chlorinated diphenyls are liquid and do not require the use of a solvent.  The process is applicable also to artificial silk of cellulose acetate or nitrate, and where the chlorinated diphenyl is sufficiently soluble in the solvent used to dissolve the cellulose derivative, it may be introduced directly into the solvent before or after the addition of the cellulose derivative.

The tongues 30 of one electrode are arranged to be at right-angles to the tongues of the other electrode to form, in effect, a two-dimensional array of transducers at those locations where the two sets of tongues intersect. This reduces the capacitance of the transducer and increases its impedance to facilitate matching of the transducer with associated circuitry. In another embodiment, Figs. 5, 7, one electrode 36 of a transducer has an array of protuberances 38 and the overlying piezoelectric wafer 12 is similarly-shaped, the other electrode 40 being in the form of a single sheet. In a modification of Fig. 7, the wafer 12 is planar and abuts the protuberances 38 (Fig. 8, not shown).
