Title: Method and apparatus for regulating the pressure and flow rate of a material
IPC: B29C48/395
Filed: 1973-01-11
Abstract: 1422654 Screw conveyers INTERNATIONAL BASIC ECONOMY CORP 11 Jan 1973 [14 Jan 1972] 1584/73 Heading B8A [Also in Divisions G3 and F4] In an expander-dryer for polymeric materials, polymeric material containing about 5 to 20% water is supplied through hopper shoot 17, Fig. 1B, and advanced along conduit 10a, Figs. 1A and 1B, by rotating feed worms 12 whereby the material is compacted by the decreasing pitch of the worms and is heated by a wall 16 which, in turn, is heated by a steam jacket or electrical wiring. Breaker bolts 18 prevent the polymer from rotating and increase the compaction thereof. The pressure in conduit 10a is maintained such that moisture in the polymer remains in its liquid state. The pressure is controlled by controlling the back pressure in the conduit by means of an adjustable throttling assembly (see Division G3) comprising an enlarged collar 33 and adjustable regulating elements (42), Fig. 2 (not shown). Heated polymer issuing from the downstream end of the throttling assembly expands and thereby causes the water to flash into vapour to reduce the water content to about 0À5%. Any fines produced during the expansion are confined by conduit 61 and are transferred together with the dried polymer to outlet 64 by compaction worms 63. Outlet plate 70 may be fitted to create a small back pressure to assist in the agglomeration of the fines.

Abstract: 261,579. Woodford, J. C. Jan. 25, 1926. Electrically-actuated valves.-In apparatus for supplying compressed air to tyres or other articles, an electric circuit controlling the actuation of a supply-valve is broken (to close the valve) by the air-pressure in a piping system when a predetermined pressure is reached. In the apparatus shown, compressed air passes from the container 1 to a chamber 3 fitted with a spring-pressed valve 4, the rod 7 of which pro-- jects to co-operate with a tappet 10 on the pivoted armature of an electromagnet 9. When the magnet is energized, the valve 4 is opened and compressed air passes through the pipe 2 to the tyre 23 through a branch 20 fitted with a cock 19. The pipe 2 leads to a chamber 16 in which is fitted all adjustable diaphragm 21 carrying a bracket 22' with an adjusting-screw 22 controlling the arm 14 of a switch 14, 15. This switch is in the circuit of a solenoid relay 13, the armature 12 of which is in the shunt circuit of the magnet 9. A lamp 46 and bell 47 are arranged in other shunt circuits also controlled by the switch 14, 15. The spindle 29 of the core 27 carries collars 30, 31 which, in the raised position of the core, close the circuits of the magnet 9 and the signal devices 46, 47. The core 27 extends into a dashpot 40, containing oil 41, and is fitted with a perforated plate 36 with a spring-pressed disc bearing on its underside. This device serves to retard the fall of the core and. in consequence, the closing of the valve 4 when the relay circuit is broken.

Title: Improvements in or relating to the refining of silicon in a ferrosilicon material
IPC: C01B33/02
Filed: 1959-01-20
Abstract: Metallic constituents are leached from comminuted ferrosilicon by treatment at elevated temperature with aqueous hydrochloric acid solution containing reducible metal ions, said solution having a pH of less than 5 and containing at least one mol/l. of chloride ions. The solution may contain up to 100 gm./l. of ferric ions and up to 25% of hydrogen chloride.  The reaction may be effected at a temperature of above 100 DEG C.  A solution containing 5% of hydrogen chloride and 80 gm./l. of ferric ions boils at 115 DEG C.  The ferrosilicon may have a particle size of 8-25 mm.  The leaching solution may be regenerated during or after leaching by oxidation with chlorine, oxygen (e.g. in the form of air), nitric acid, a chlorate, or by electrolysis and addition of further acid.  The hydrogen chloride may be initially produced by chlorination of ferrosilicon in the presence of an aqueous solution of various metal salts.  The resulting silicon is washed with water.  Washings from a later stage may be used in an earlier stage.  Washings from an earlier stage may be combined with the leaching solution.

Title: Improvements relating to adjustable thermostatic control mechanisms for electric bread toasters
Inventor: LAWSER JOHN JACOB
IPC: H05B1/02
Filed: 1957-01-21
Abstract: 805,866. Electric toasters. PROCTOR ELECTRIC CO. Jan. 21, 1957, No. 2160/67. Class 28 (1). [Also in Group XXXVII] A thermostatic control switch has a thermostatically - actuated contact and a normally stationary co-operating contact mounted on an adjustable member with an inclined face engaged by a movable cam which in addition to its primary movement can have its point of engagement along the inclined face changed, so moving the adjustable member and stationary contact to a different position where the primary adjustment of the cam will be through a different angle. The bread carriage 11 is manually lowered by knob 12 and is held by a latch until it is released by a thermostat 13 which responds to the surface temperature of a bread slice 14. The toaster has a crumb tray 15 and a colour selector finger-piece 16 with an adjustment screw 17. Thermostat 13 is mounted on a central channel support 18 forming part of the chassis of toaster 10. The thermostat comprises an L-shaped support arm 19 held with bus-bar 22 by screws 20, 21 in channel 18 being insulated from the latter by strips 23, 24 located by ears 25, 26 in channel 18. Welded to the top of arm 19 are a U- shaped bimetal 27 and a shield element 28 which co-operates with an extension 29 of support 19 to shield strip 27. Strip 27 has a short wide compensating leg 30 and a long narrow primary leg 31. Secured to the lower end of leg 31 is an L-shaped extension 32 whose end portion 33 carries a wire contact 34 to engage a relatively stationary and preferably silver contact 35 protected by a porcelain shield 36 secured to a metallic support 37. Contact 35 has a threaded extension 38 by which it is secured to L-shaped support 37 from which it is insulated by a shoulder of the porcelain shield and an insulating washer 39. Extension 38 forms a terminal for a wire 40 which with bus-bar 22 is included in the energized circuit. Support 37 is fastened to a leafspring member 41 riveted to an extension 44 of support 18 and is biased to the left, Fig. 2. A cam follower lobe 45 with a sloping face on support 37 is engaged by a manually-operated cam 46 with a narrow face extending transversely of the face of follower 45. Cam 46 is preferably formed on a spring steel member 47 secured to an arm 48 pre-biased downwardly and slotted at 50 to receive adjusting screw 17. This screw threads into the hollow rivet 49 and forms a pivotal support for arm 48, washers 51 being provided one of which is a spring washer to provide resistance to the pivotal movement of arm 48. Movement of finger-piece 16 pivoting cam 46 about rivet 49 effects adjustment of contact 35. Cam 46 may be adjusted vertically by screw 17 if the markings indicating the positions of piece 16 for different degrees of toasting prove to be incorrect.
