Title: Device for continuous production of cork soles for footwear
IPC: A43D8/00
Filed: 1973-11-23
Abstract: 1450552 Injection moulding shoe soles MACHINERY SERVICE & REPRESENTATION ETAB 23 Nov 1973 [24 Nov 1972] 54380/73 Heading B5A The invention relates to a machine for injection moulding a stiffening core of thermoplastic material in a two-layer cork sole for a shoe. The machine comprises a plurality of moulds 10, 10<SP>1</SP> (Fig. 3) carried by mould holders 6, 6<SP>1</SP> pivotally arranged around the edge of a rotary table 5, an injection device 23 (Fig. 4) comprising a plasticizing cylinder 27 with a pair of nozzles 28 which are movable vertically by a double-acting cylinder 32, ejector means and a belt conveyer 79 for removal of the finished soles. The moulds are opened and closed by cylinders 16, the two mould holders 6, 6<SP>1</SP> being interconnected by a pair of gears 9, 9<SP>1</SP>. At the injection station the mould is held closed by a piston 33. The moulds may be of different sizes, the quantity of material injected being determined by means of a limit switch 38 actuated by calibrated elements 39 which can be adjusted to the right or left. The elements 39 are mounted on a disc 40 which is rotated by means of a ratchet and toothed wheel 41 in step with the movements of the table 5. The table 5 is rotated step-wise by means of a self-braking motor 49 through a belt 50, pulley 51, and worm gear 52, 53. Gear 53 is on a shaft 54 on which is mounted a member 57 which engages in a series of radial slots 61 in the lower face of the table 5. The table may be provided with a casing 68 (Fig. 1) having two openings 69, 70, the latter having a safety gate 71 with a pair of proximity switches (72). The moulds may be cooled by a fan 73. The moulds are loaded through opening 70, and finished soles ejected through opening 69 on to conveyer 79. Thence the articles are delivered to a second conveyer 80 provided with obliquely arranged arms 83 for diverting the soles into appropriate containers 85. Arms 83 can be raised and lowered by cylinders (82) Fig. 7 (not shown). A storage unit 91 (Fig. 1) contains sole blanks of different sizes on support surfaces 93 which are moved in synchronism with the table 5, (see also Fig. 8, not shown). A pair of ejector rods (75, 75<SP>1</SP>) Fig. 9 (not shown) and a guide member (77) fit into three through holes (12, 12<SP>1</SP>, 12<SP>11</SP>) in the mould, and are operated by a double acting cylinder (78).

Filed: 1970-11-24
Abstract: 1335195 Electro-deposition, ultra filtration and ion exchange P P G INDUSTRIES Inc 24 Nov 1970 [25 Nov 1969] 55769/70 Heading C7B At least a portion of an electro-deposition bath comprising a synthetic resin ionically solubilized in an aqueous medium is subjected to ultrafiltration and the ultrafiltrate is contacted with an ion-exchange resin to raise or lower the pH of said ultrafiltrate depending on whether the ultrafiltrate is acid-containing or base-containing respectively. The ultrafilter may be microporous, a diffusive gel membrane, or preferably an anisotropic membrane and is designed for example to retain the vehicle resin and pass water and solutes of low molecular size. The process is batch or continuous, at a pressure of 10-150 p.s.i., the bath at the face of the filter being kept in motion by mechanical stirring or a force vector parallel to the filter surface to avoid clogging the filter. Retained matter from the ultrafiltration may be returned to the bath, optionally after reconstitution with water. The bath may comprise a synthetic polyacid resin solubilized with base; in this case the ion-exchange resin is a cation-exchange resin, e.g. of the carboxylic acid type or sulphonic acid type, or may comprise an acid-solubilized polybasic resin; the ion-exchange resin is then an anion-exchange resin of the polyamine or quaternary ammonium type. The ion-exchange process is batch or continuous, performed concurrently or intermittently with the ultrafiltration, a suitable apparatus being described.

Abstract: 1379758 Measuring magnetic fields MISHIMA KOSAN CO Ltd 3 Dec 1971 [3 Dec 1970] 56366/71 Heading GIN [Also in Division H3]  A magnetic modulator comprises a core having two windings 4, 12, each of which is provided with a respective capacitor 5, 13 and also with a respective A.C. bias circuit 6, 14. An A.C. driving source at the frequency to which the circuits 4, 5 12, 13 are tuned is coupled to terminals 1, 2 of an energizing winding, 3 and the windings are so arranged that, in the absence of any control signal, no signal is induced into windings 4, 5. Application of a control signal, either in the form of a signal applied to an additional winding, not shown, or a magnetic field to which the core is exposed, causes an unbalance which produces an output. The bias signals switch the polarity of this output and the relative instants of switching are determined by the magnitude of the control signal, so that if terminals 11, 19 are connected, pulses of the signal at 1, 2 appear at the output 10, 18, the width of the pulse depending on the magnitude of the control signal.

In a method of recovering a non-oxide compound of a metal having a melting point above 1650‹C. from an electrically conductive material in which metal compound is present, e.g. as a constituent of an alloy, the material is made anodic in an acidic or neutral, non-oxidizing electrolyte, using an electrolysing voltage such that a major part of the metal(s) not included in the metal compound is dissolved and a major part of the metal compound is not dissolved or decomposed. The metal compound may be a boride, carbide, silicide, nitride, phosphide or arsenide, and the metal of the compound may be chromium, molybdenum or tungsten. The material of the anode may be cast in plate form, or granulated and held in a titanium or an electrically and chemically inert container. A diaphragm may be used, the dissolved metal then being recovered by purification of the anolyte. The compound may initially be formed by treating the material containing the high melting point metal with a non-metal of Groups III, IV or V of the periodic table.

Title: Pressure vessel for a nuclear reactor

Filed: 1972-12-27
Abstract: 1412788 Reactor pressure vessels SIEMENS AG 27 Dec 1972 [23 Dec 1971 7 Aug 1972] 59687/72 Heading G6C A nuclear reactor pressure vessel comprises an inner, steel pressure container 1 having a cover 2, and an outer, open-topped, reinforced concrete container 3, and includes an arrangement of pivotable hooks 24 for retaining the cover 2 and/or the container 1 in position. In one embodiment (right-hand side of the Figure) the container 1 is supported within the container 3 by means of brackets 9 which rest below coolant unions 5. A lining 20 of steel, ceramic or other balls, which can be removed through a conduit 28, and cooled, insulating concrete 15 separate the walls of containers 1, 3. In the region of the bottom of the container 1, the balls are replaced by a steel liner 18. The cover 2, which is surmounted by a steel ring 26, is retained by means of the hooks 24 whose engagement portions coact with inclined surfaces on the ring 26 such as to be selflocking under the influence of axial pressure upwardly on the cover 2. A heat-insulating shield 34 is positioned above the coolant unions 5. In a second embodiment (left-hand side of the Figure) the container 1 is supported at its base by bolsters 7 around which cooling tubes are disposed. The container 3 comprises tubes in which reinforcements 31 extend axially to be secured to a top member 22. The hooks 24 can be pivoted hydraulically. In the cold state of the pressure vessel, a clearance exists between the engagement portions of the hooks and the inclined surfaces 27 of the ring 26; the clearance is less than the expected expansion of the container 1 during raising of its temperature to normal operating levels whereby, at such levels, the forced engagement between the hooks 24 and ring 26 causes stress loading of the reinforcements 31 via the member 22 on which the hooks are secured. The loading due to thermal expansion can be limited by means of openings. In another embodiment (not shown) two sets of supports 7 and 9 (as in the above embodiments) are provided for the container 1. In its cold state, the container 1 rests only on supports 9. As its temperature is raised to operating level, the downward expansion of container 1 first causes it to become supported, also, on supports 7. As further heating occurs, expansion causes the container 1 to lift off the supports 9 and subsequently to engage, via ring 26, with the hooks 24.

Symmetrical devices may be made by forming shorted-emitters on both sides of a semi-conductor body.
