Title: Improvements appertaining to screw cutting tools
IPC: B23G5/06
Filed: 1929-06-26
Abstract: 335,578. Standard Telephones & Cables, Ltd., and Clarke, G. W. June 26, 1929. Screwing - dies; taps. - In a screwcutting die or tap the cutting angle varies over the length of the tool, and a single cutting- edge only may be provided. A tap is formed by cutting a full screw-thread on a tapered bar 1 and then removing a portion of the tapered part so as to form an oblique face 3 whose edges 4 - - 16, Figs. 1 and 3, constitute the cutting- edges of regularly increasing angle. The small diameter of the tap corresponds to the size of hole to be tapped and the large diameter to the finished thread. The first teeth cut a deep narrow groove which the succeeding teeth deepen slightly and widen whilst the teeth 12 - - 16 have a reaming or burnishing action. Alternatively, the screw-thread may be cut on a parallel bar and the tops of the first threads tapered as shown in Fig. 6, or the bar and the tops of the threads may each be slightly tapered. In another modification in which the depth of cut does not increase uniformly, the bar consists of alternate cylindrical and conical portions l, k, Fig. 11, and in this form the cutting angle may also be made to vary irregularly by cutting along a curved surface as shown in this Figure. The variation in cutting angle may also be produced by cutting a tapered flute in the tapered and threaded bar. A screwing die is formed from a block 73, Fig. 17, by providing a screwed bore tapered from n to p and then cutting away in an oblique plane n, q. The larger diameter of the bore is sufficient to allow the unthreaded work to penetrate as far as the first cutting tooth 76, and the variations of cutting angle and depth of cut are similar to those of the tap shown in Figs. 1 and 3. Alternatively, the bore may be parallel and the tops of the first cutting teeth tapered, or both the bore and the teeth may be tapered as shown in Fig. 21. In this Figure the block is cut away on a curved surface 74 similarly to the tap shown in Fig. 11. The other features of the tap may be incorporated in the die and a single curved or tapered flute may be provided. The tap or die may be modified in other ways, such as by omitting alternate threads over the whole or a portion of its length or several rows of cutting-edges, each having teeth of varying angles, may be provided. Specifications 8345/87, [Class 61, Hand tools &c.], and 7109/01 are referred to.

Title: Dishwashers
IPC: A47L15/42
Filed: 1973-04-26
Abstract: 1372164 Dishwashing machines GENERAL ELECTRIC CO 26 April 1973 [12 May 1972] 19795/73 Heading A4F In an automatic dish washing machine having means such as a pump 19, Fig.1 (not shown), and sprayer (25) for circulating washing liquid accumulated in a washing chamber, and means including a sump (20) for draining the washing liquid from the washing chamber, a soil removal receptacle 31 is provided independent of the sump and is arranged so that the circulating washing liquid fills it and overflows through a filler screen 32. The receptacle 31 receives through slots in a cover plate 37 washing liquid flowing down a wall of the washing chamber, which liquid impinges upon the upper side of the screen 32 and jars it thereby dislodging soil from its lower side. During a washing cycle soil passes from the receptacle 31 to a hopper 35. At the end of a washing cycle a valve is operated by electrcial control means to divert the output of the circulating pump from the sprayers to a conduit 27 and thence into the hopper 35 via an inlet valve 56 opened by liquid pressure, at the same time a further valve 57 on the valve stem 55 is closed to cut-off communication between the hopper 35 and the receptacle 31, so that pressure builds up in the hopper 35 to open a non-return valve 60 leading to a drain pipe 44 to which the soil in the hopper 35 is flushed by the liquid. During flushing of the hopper 35 the receptacle 31 is drained into the washing chamber by the opening of a valve 65 by the upward movement of the valve stem 55. Alternatively the hopper 35 is flushed by a jet pump.

Title: Improvements in and relating to the production of artificial filaments, films and similar materials
IPC: B29C48/08
Filed: 1937-07-19
Abstract: 501,197. Artificial filaments, films, etc.; artificial resins. DU PONT DE NEMOURS & CO., E. I. July 19, 1937, No. 19921. Convention date, Feb. 15. [Classes 2 (ii) and 2 (iii)] Artificial filaments, films, and similar materials are made from linear condensation polymers particularly polyamides, by processes wherein the hot or molten polymers are subjected to rapid chilling. The polymer may be chilled by immersing it in or spraying it with a non-solvent liquid, e.g. water, alcohols, ketones, ethers, esters, hydrocarbons, or chlorinated hydrocarbons. A cold inert gas may be used for the chilling step. The chilling treatment may be carried out on the formed filaments, films, or ribbons. Polyamides derived from diamine-dibasic acid mixtures or from monoamino monocarboxylic acids or their amide forming derivatives may be used. Other linear condensation polymers which may be used are polyesters, polyacetals, polyethers, and polyester-polyamides. Polyhexamethylene adipamide, polytetramethylene sebaoamide, polypentamethylene sebacamide, polydecamethylene adipamide, polydecamethylene p-phenylene diacetamide, poly-p-xylylene sebacamide or similar compounds derived from diamines and dicarboxylic acids may be used. Polyamides derived from 6-amino-caproic acid, 9-amino-nonanoic acid 11-amino-undecanoic acid, or similar monoamino. monocarboxylic acids may be used. Subsequently to the rapid chilling operation the filaments, films, and other materials may be subjected to colddrawing, if desired after a preliminary soaking in water or other non-solvent. The chilling process increases the toughness of the products and enables them to undergo bending without breaking, and it facilitates subsequent colddrawing treatments. Polyamides of high intrinsic viscosity may be used. Filaments or ribbons may be obtained by extruding the molten polyamide into cold water. In an example a molten polyhexamethylene adipamide is extruded directly from the autoclave in which it is made through a spinneret at high temperature and pressure into cold water so as to form tough bristles whichare subsequently cold-drawn. In another example, a solution of the polymer in formic acid is flowed on to a glass plate and the solvent is evaporated. The plate and the film thus formed are heated until the polymer has melted and become clear. The plate and film are then plunged into cold water. A clear transparent film is obtained. This may subsequently be subjected to stretching. The polyamide may contain additions of plasticizers, e.g. o-hydroxydiphenyl or diphenylolpropane, pigments, fillers, dyes, resins, oils, cellulose derivatives,- or disinfectants. Titanium dioxide, zinc oxide, or iron oxides, may be used as pigments. The filaments may be used as fish line leaders, tennis strings, musical instrument strings, surgical sutures, artificial hair, and dental floss. Specifications 461,236, 461,237 and 491,111 are referred to.
