Abstract: 1,181,117. Foot covering. W. W. ARTZT. 26 June, 1967 [1 May, 1967], No. 29312/67. Heading A3V. The foot portion e.g. of children's pyjamas, tights &c. comprises a seamless sole 28 a straight toe 26 formed by folding the end 24 of a blank (10), Fig, 1 (not shown), a tapering upper portion 24 and triangular portions 30, 32 folded along edges 34, 36 and seamed to the portion 24 at 38, 40. A blank of knitted fabric has the wales running longitudinally thereof and the seams 38, 40 are therefore on the bias relative to the wales. The girth of the foot portion can be reduced by folding the portions 30, 32 outwardly along lines 46, 48 and sewing the edges of the darts so formed at (50) (Fig. 3 not shown) to the edge 16 of the foot opening 42 to which a leg portion of a garment is sewn. Instead of a one-piece blank, an initially separate portion 24 may be sewn to the remainder of the blank along the line at which the blank is folded to form the straight toe 26.

Title: Reversible cinematograph apparatus
IPC: G03B1/18
Filed: 1948-11-12
Abstract: 667,372. Kinematograph apparatus. DEBRIE, A. V. L. C. Nov. 12, 1948, No. 29491/48. Class 97 (i). A film feeding mechanism comprises upper and lower film sprockets with between them, a curved film guide in which the gate aperture is formed, and, between the guide and the lower sprocket, a pivoted beater member which is moved downwards periodically in synchronism with the sprockets to feed the film intermittently. A detachable film feed spool and a non-detachable take-up spool are used. The projector shown has a lamp 23, condenser 22 and projection lens shown dotted at 21. The film is wound by sprockets 3, 11 and passes through the film guide 6 and round rollers 5, 8. The latter is pivoted on an arm 9, pivoted at 27 and carrying a laterally projecting cam portion 20 which is struck periodically by one of a number of pins 25 carried by a gear-wheel 17 on the shaft of the sprocket 11. The roller 8 is thus moved downwards to enlarge the film loop 24 at the expense of the loop 26<SP>1</SP> and feed a frame of film through the channel 6 past the aperture 7. The pivot 27 may be adjustable, for example by slide-and-screw mechanism, to maintain accurate framing. The gear-wheel 17, and the similar gear 16 driving the sprocket 3, are driven from a common pinion 18. After projection the film is rewound on to the upper spool merely by reversing the drive to the mechanism. During this movement no loop is formed at 26<SP>1</SP> so that the roller 8 remains in its lowest position and the pins 25 do not strike the cam 20. The detachable feed spool has a circular hole in the centre of one flange, to engage its spindle, and a smaller square hole in the other flange to provide a driving engagement with a squared portion at the outer end of the spindle. Lightening holes are formed in one flange only so that the flanges are distinguishable by touch.

Class 43 [Also in Group XVIII] In a jewel mounting a jewel is mounted on a support to which movement is imparted by a mechanism located in a case concealed by the jewel and associated ornamental elements and the mechanism .is wound by a winder driven by toothing, rigid with the jewel assembly support, when the ornamental elements; rigid with the mechanism case, are acted upon the connection between the case and the support for the jewel assembly being effected through a member rotatable in the support. In the arrangement shown in Fig. 2 a base plate 1 provided with a brooch pin 2 has a circular rack 3 welded on its upper surface. A mechanism case 5 mounted in an enclosing member 4 rotatably mounted in an aperture in the base plate 1 has a winder 6 engaging the circular rack 3, the enclosure member 4 being held in position by a plate 20. A cover 8 of the enclosure 4 is provided with lugs 11 to which another cover 9 is secured by screws 10 on which cover 9 are mounted ornamental elements 13.

Title: Improvements in or relating to siliceous products
IPC: C08K3/36
Filed: 1947-11-12
Abstract: Siliceous compositions are obtained by hydrolysing a hydrocarbon-substituted halogenosilane to form the corresponding siloxane in the presence of finely-divided anhydrous silicon oxide in the form of an aerosol obtained by the combustion of a combustible silicon compound, e.g. silicon tetrachloride, and separating from the reaction mixture as product a composition of the silicon oxide and the siloxane.  The yield of siloxane is greater than that obtained in the absence of silicon oxide. Preferably the silanes used as starting materials contain 1.7 to p  2.3 organic substituents (e.g. methyl, ethyl, benzyl) per silicon atom.  The products may be liquids, greases or solids, and may be used as plastics or waterproof coatings for electrical apparatus. Products obtained from dibenzyl silicon dichloride may be incorporated in cellulose acetate or polyvinyl acetate.  In examples (1) a mixture water is gradually added to a mixture of dimethyl silicon dichloride and silica obtained by combustion of silicon tetrachloride, and the product, after removal of water, is heated in a vacuum at 150-250 DEG  C.  The gel obtained, after malaxation resembles petroleum jelly and yields a colloidal dispersion in hydrocarbons; (2) the process of (1) is repeated, the product is washed with methyl alcohol, and a thixotropic gel is obtained.  Specifications 605,036 and 640,162 are referred to.ALSO:Waterproof compositions of silicon oxide and a siloxane are obtained by hydrolysing a hydrocarbon - substituted halogenosilane in the presence of silica obtained by combustion of, e.g., silicon tetrachloride.  The products may be used to coat electrical apparatus or wire.  In hydrocarbons or other solvents they give stable colloidal solutions.

Abstract: 324,116. Gee, F. W. Oct. 19, 1928. Fats, extracting.-Waste food from hotels, restaurants, and the like is fed without previous treatment into a hopper 10, whence it is carried bv a bucket elevator 11 into the middle cone 12 of a rotary grading and washing machine. This machine comprises a series of concentric rotatable perforated cones, the cone with the coarsest apertures being innermost. The machine has a steam heating jacket 16 and hot water is introduced to the innermost cone through a pipe 17. The wash water carrying the greater part of the free fat is discharged through an outlet 18 into settling tanks 19, 20, 21, from which the fat is discharged into a clarifier 22. The small quantity of food material that escapes the sieves settles in the tanks 19, 20, 21 and can be discharged into another tank 23. From here it may be passed through a filter press and subsequently be treated with the other residues. The oversize material from each of the sieves is discharged through shoots 24 on to conveyers 27, 28. Foreign matter is picked out as the material moves along these conveyers. The solid fat matter thus isolated is crushed or minced and the ordinary methods of dry rendering are employed to extract the fat and to utilize the residues for poultry and animal foods. The water separated from the fat in the tanks 19, 20, 21 is bye-passed to a tank 34 in which it is reheated and then pumped back to the washing machine. Specification 324,117 is referred to.
