IPC: B22D29/00
Filed: 1943-03-16
Abstract: 575,478. Electric heating. GENERAL MOTORS CORPORATION. March 16, 1943, No. 4236. Convention date, March 20, 1942. [Class 39 (iii)].; [Also in Groups II, XII and XXII] Relates to the removal of moulded objects fromcores, particularly porous metal objects from - permanent cores, and consists in the utilization. of different thermal expansion of the object and core to effect the loosening. In the manufacture of tubular articles from metal powder a mould 22 fitted with a core 24 is filled with metal powder. After sintering the article 26 shrinks from the mould and on to the core which is then removed carrying the article with it, and is supported in an inverted position in an opening in an electric furnace having an element 36 surrounding the article to heat it by induction or in the case of a non-metallic article by radiation from a resistor. The furnace preferably has a water seal at 40 and inert or reducing gas is supplied at 44. When the article is heated sufficiently it falls from the core and is cooled or quenched. In the case of steel aricles, particularly those cast from molten metal, the falling may be delayed until the correct temperature for hardening has been attained. The tank 42 may be filled with oil for the impregnation of porous articles. In a modified furnace the heating is effected by gas burners 54 Fig. 7 arranged to deliver the flame tangentially to the article. The mould may be of ceramic material, of oxidized chromium steel, or of steel lined with graphite or alumina.

Patent GB-373141-A (GB)
Title: Improvements in or relating to the covering of wire thread-like or filamentary material and the like with india rubber, gutta-percha, balata or similar materials or compounds thereof and apparatus therefor
Filed: 1931-02-16
Abstract: The process for coating wire, thread-like and filamentary materials with india-rubber, gutta-percha, balata or like material claimed in the parent Specification is modified by passing the wire &c. through a bath containing an aqueous dispersion of the rubber or other material, causing it to emerge therefrom coated uniformly with the dispersion, coagulating the coating by contacting it with a gaseous or liquid coagulant before allowing it to come into contact with any solid body, and finally drying the coagulated coating.  The coagulant may be in the form of a spray or a current of gas or vapour.  A number of coatings may be applied, each being coagulated or set before the next is applied. Setting or dehydrating media may be used instead of coagulating media.  The dispersions may consist of or contain rubber, gutta-percha, balata or similar vegetable resins, occurring naturally or artificially obtained.  Artificial dispersions may include those of coagulated, vulcanized or synthetic rubber, or waste or reclaim.  Any known compounding and vulcanizing ingredients may be included.  Concentrates such as are described in Specifications 219,635 and 290,313, [both in Class 70, Indiarubber &c.], may be used.  The coagulating current of gas or vapour may be for example cold or heated acetic or formic acid. Setting media may be for example the liquids described in Specification 303,544, [Class 70, Indiarubber &c.].  In one example, cotton yarn or thread is passed round a pulley immersed in a bath containing a latex mixing prepared as described in Specifications 290,313 and 307,315, [both in Class 70, Indiarubber &c.], having a total solid content of 68 per cent and comprising rubber, sulphur, tetramethyl-thiuram-disulphide, zinc oxide, transformer oil, and carbon black.  The yarn emerges from the bath through a tube of the kind described in the parent Specification and passes through a small chamber where it is sprayed with a 20 per cent solution of acetic acid.  The tube is inclined at an angle of about 30 DEG  to the vertical in order to counteract the tendency of the coagulant to run down the thread.  The chamber is also inclined and provided with means to catch excess coagulant. During the short travel of the thread after leaving the spray chamber, the coating is set sufficiently to prevent distortion and sticking to the pulleys.  In another example, cotton yarn or thread is passed round a pulley immersed in a bath containing a latex mixing of 30 per cent solid content and comprising rubber, sulphur, tetramethyl-thiuram-disulphide, zinc oxide, mineral oil, and pigment. The yarn emerges directly from the surface of the bath and passes into a vertical tube through which hot air is blown.  At the bottom of the tube a slow additional current of air charged with acetic acid vapour is injected, the air being bubbled through glacial acetic acid.

Filed: 1940-03-14
Abstract: 539,669. Glass manufacture. BRIDGES, E. G. March 14, 1940, No. 4831. [Class 56] A glass-working machine of the rotary type is connected to the driving shaft by means of a clutch, and is provided with pneumatically operated means for disengaging the clutch and stopping the 'rotation of a mould should it not complete its opening or closing movement at the correct time. Manually operated devices are placed at different parts of the machine to enable the operator to stop it from any one of a number of positions. Fig. 1 illustrates a machine of the double table type in which a parison mould table 10 and a finishing mould table 12 are interconnected, and are rotated intermittently by a Geneva wheel 14 the rotor of which is driven by a' shaft 16. This shaft is connected to the main driving shaft 18 through a clutch 17 which is opened and closed by a lever 65 actuated by a pneumatic cylinder 62. The parison moulds 11 are opened by a stationary pneumatic cylinder 20 having a slide 23 which engages a roller 24 on a yoke 25 linked to the mould. When a mould is opened fully, a button 40, Fig. 4, adjustably secured to the piston rod 22 of the cylinder 20, engages the stem 37 of a valve 35. Similar valves are operated when the finishing moulds 13, Fig. 1, are opened at the transfer position by a cylinder 26 and at the discharging position by means of a cylinder 32. The valves 35 are connected in series by pipe lines with a valve 46 and with the main air supply conduit M. The valve 46 is also connected to the conduit M and to the main timing- device 53 driven by the shaft 16. If one of the pistons of the cylinders 20, 26 and 32 fails to open to its inactive or closed position, or to remain in that position, its associated valve 35 will remain closed and compressed air is admitted to the cylinder 62 to disengage the clutch 17 and prevent further movement of the mould tables. If a finishing mould piston 33 completes its movement without opening the mould, the roller 30 which should be engaged by the piston rod engages the stem of a valve 35a and operates the clutch cylinder 62. Another valve 78 also opens the clutch if engaged by an unopened mould. The valve 78, if operated, also operates a valve 80 to cause a cylinder 84 to apply a brake 87 to the mould table. A hand-operated trip valve 90 releases the brake when machine is to be started again. Other hand-operated valves 95, placed in selected positions around the machine, enable the operator to open the clutch and stop the machine in cases of emergency. Specification 386,012 is referred to.
