Title: Method of and machine for injection moulding
IPC: B29C45/72
Filed: 1943-05-24
Abstract: 568,050. Automatic control systems. TUCKER, W. R. May 24. 1943, No. 8228. [Class 38 (iv)] [Also in Groups V, XI and. XIII] Material for injection-moulding is heated by a body of substance which is maintained substantially at the temperature at which it is changing phase, e.g. undergoing fusion. The substance may be metals, sulphur, chemical compounds, e.g. salts, and eutectic mixtures, many examples being given, and may be heated by eddy currents or by immersion or other heater elements. Fig. 1 shows an arrangement in which a bath 10 of molten metal &c. surrounds the injection cylinder 1. The bath is electrically heated by an element 11 disposed between heat insulation 13 and heat conduction 9a. The temperature of the bath is' indicated and controlled by an instrument 17, 18. The modifications : (1) Fig. 2 (not shown). The bath 10 is in three separate zones, each having its own heating element and each being controlled by an instrument 17, 18. (2) Fig. 3. The bath 24 is such that it is electrically conductive when molten, but non-conductive when solid, and may be a fused salt, a crystalline hydrate at the temperature at which it loses water. When the outer part of the bath melts, current passes below contacts 27, the switch 31 is opened to the position shown by solenoid 30, and heating of the bath stops. When the outer part of the bath re-solidifes, current cannot bridge contacts 27, switch 31 closes, and heating recommences. (3) Fig. 4 (not shown). The bath is in two electrically-heated parts, one large and one small. The large part has 1 heater turn per unit length, whereas the small part in which the. controlling thermostat is mounted has 1 ¢, and is kept at 4‹ C. above the bath melting-point, the large part being accordingly kept at a lower temperature. (4) Fig. 5 (not shown). The bath is a material which expands on melting, and this expansion moves a piston to open a switch to stop the heating.

Title: Improved method of making permeable sheet materials, and products resulting therefrom
IPC: F16J15/10
Filed: 1922-03-21
Abstract: 177,778. Gibbons, W. A., and Ritter, H. W. March 31, 1921, [Convention date]. Fabrics with multiple superposed coatings; single coatings; compound fabrics and sheet materials.-Artificial leather &c. is made by mixing a plastic material such as a rubber mixing or nitro-cellulose composition with a filler holding a liquid' or gaseous pore-producing agent, sheeting the mix, expelling all or part of the poreproducing agent, and setting the sheet in a pliable, permeable condition. The. sheet is preferably made on or applied to a fabric backing. Several examples are given, of which the following is typical : 100 parts of pale crepe, 10 parts of zinc oxide, 4 parts of p-toluidine, 2 parts of sulphur, 4 parts of dibutyldixanthic-disulphide. are mixed with sufficient solvent naptha to produce a pasty mass. 100 parts of cotton fibre saturated with water are mixed with this composition. The mass is sheeted or calendered on to a fabric which has been thinly coated with rubber. The sheet may be embossed, varnished, &c., and is then heated to expel the water and so form minute pores, and to vulcanize the composition, a temperature of 200 F. for 10-30 minutes being sufficient. The accelerator may be added more safely at a later stage of the mixing. Other fibres may replace the cotton, and other non-solvent liquids the water. Dry fibres or substances such as magnesium carbonate may be employed in some instances, the air entrapped in their interstices being sufficient on heating to produce pores. In such cases, the amount of air may be increased by blowing it into the mixture. A suitable nitro-cellulose composition consists of pyroxylin 12 gm., castor oil 12 gm., cotton fabrics (wet) 10 gm., amyl acetate 200 cc., benzol 125 cc., and carbon black 1 gm. The mixture is spread on fabric, and dried at about 100 C. between coats. The invention also includes blended nitro-cellulose and india-rubber composition permeable sheets, and sheets of superposed layers of nitro-cellulose and india-rubber compositions.

Title: Improvements in gearing for starting motors and electrical generators as used on internal-combustion engines
IPC: F02N15/04
Filed: 1921-03-17
Abstract: 179,032. Armstrong Siddeley Motors, Ltd., and Smith, F. R. March 17, 1921. Turning-gear.-An electric starter for internalcombustion engines is of the kind in which an electric motor B drives the engine through planetary gearing at starting, the gearing being afterwards locked by an axial movement of the sun pinion G so that the motor is driven as a generator at engine speed. The sun pinion G is arranged for direct clutching engagement with the sprocket wheels F, toothed gear, or the like connected with the engine. In the form shown, a sun pinion G is mounted upon a quick thread A<2> on the motor shaft A, and carries between thrust bearings the planet-pinion carrier H. The planet pinions M have two sets of teeth, engaging respectively the sun pinion G and a second sun pinion N integral with the chain-wheel F geared to the engine to be started. At starting, the rotation of the shaft A moves the pinion G to the right and brings a clutch face J on the carrier H into engagement with a clutch face K on the casing, so that the shaft A drives the engine through the planetary gearing. When the engine overruns the motor, the pinion G moves to the left and brings clutch faces G<2>, 0 into engagement, locking the pinions G, N together, so that the gearing rotates solidly at engine speed. The starter casing E is mounted eccentrically about a part Y of the engine, so that rotation of the casing may be used to tighten the sprocket chain Z.

Title: Improvements relating to magnetic crack-detecting apparatus
Inventor: WALLEY JAMES WILLIAM
IPC: G01N27/84
Filed: 1952-04-02
Abstract: 711,521. Magnetic tests. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. March 30, 1953, [April 2, 1952; June 4, 1952.] Nos. 8423/52 and 14099/52. Class 37. Apparatus for examining ferrous metal parts for cracks by magnetizing the part and painting with a magnetic powder of fluid to make the cracks visible is characterized by the use of two adjustable head stocks for locating the metal part, at least one of which has a magnet whose position relative to the test part is adjustable to a position where it induces magnetism in the test piece, or to a position where its poles are bridged by a keeper. As shown (Fig. I) two aligned mild steel head stocks 1, 2 are adjustable mounted on a base plate 3 with one head stock electrically insulated from the base plate by suitable insulation 4. The left hand member I comprises a steel cylinder 6, a non-magnetic metal ring 7 and a steel end cover 8 having an annular ring 9. A permanent magnet I2 with pole pieces I3 is located inside the rings, and is attached to a rod I6 having a handle I4 whereby the magnet may be moved axially inside the rings 6, 7, 9. The other headstock 2 carries a cylindrical block I8 spring- loaded by a spring 20 to hold the test piece between the end faces of the headstocks which are covered by copper braid pads I0, IO<SP>1</SP> to give good electrical contact. The position of the magnet I2 determines the strength of longitudinal magnetization of the test piece, to enable transverse cracks to be shown, and may be indicated by a scale on the extreme part of the rod I6, a running nut 22 on a threaded portion of the rod facilitating the exact repetition of the position of the, magnet I2 by limiting the movement of the magnet to the right. Circumferential magnetization, to locate longitudinal cracks, may be obtained by passing current directly through the test piece. In an alternative arrangement the magnet I2 moves in a cylinder which is spring-biased axially to hold the test piece, movement of the handle I4 in one direction causing withdrawal of the outer cylinder against the spring to allow the test piece to be inserted, and movement of the handle I4 in the other direction causing the magnet to go forward to the test position. Both headstocks may contain magnets, and the magnetic powder may be used with the residual magnetism after magnetization. Specification 668,73<SP>2</SP> is referred to.

Title: Trichloroacrylyl chloride
IPC: C07C51/58
Filed: 1953-03-30
Abstract: Trichloroacrylyl chloride is made by reacting at an elevated temperature hexachloropropene with one or more oxides of iron. Ferrous, ferric and ferrosoferric are specified oxides of iron. Naturally occurring ores, e.g. hematite and magnetite, may be used but should not be hydrated.  Reactants are preferably used in stoichiometrical quantities.  Inert diluents, e.g. aliphatic hydrocarbons and chlorinated hydrocarbons of little or no unsaturation and I.B.P.'s of above 200 DEG  C. such as paraffin oils, kerosenes and keryl chlorides, may be present.  Excess chloropropene also acts as a diluent.  Temperatures specified for reaction are 110-300 DEG  C. especially 140-220 DEG  C., and particularly 160-, 200 DEG  C.  Atmospheric, sub- or super-atmospheric pressure may be applied.  The reactants should be mixed gradually generally the oxide being added to the propene. Thus a slurry of oxide in the propene may be added to a quantity of the propene pre-heated to about 190 DEG  C. with subsequent reaction at 170 DEG  C.  Trichloroacrylyl chloride may be distilled off as formed from the reaction mixture or recovered after reaction has ceased.  Examples are provided in which ferric and ferrous oxides are used.
