Patent GB-552050-A (GB)
Title: Improvements in extrusion devices, for example for extruding raw doughnuts
IPC: A21C3/00
Filed: 1941-07-18
Abstract: 552,050. Valves. LOWE CORPORATION, J. July 18, 1941, No. 9105. Convention date, May 20. [Class 135] [Also in Group V] In a doughnut machine of the cutter-sleeve type in which the batter is sucked from a hopper into the extrusion chamber by vacuum and expelled therefrom by compressed air, the cutter sleeve acts as a valve to open and close both the outlet and inlet of the extrusion chamber. The sleeve 25 slides between the walls 20a of the central opening in the hopper 11 and a fixed depending tube 16 which constitutes the extrusion chamber. When the sleeve is in its lowermost position and suction is being applied through a pipe 14, batter passes from the hopper through openings 18 in the tube. As compressed air enters from the pipe 14 the sleeve rises to its middle position and covers the openings 18, as shown. Later, while compressed air is still being applied, the sleeve rises to its uppermost position, allowing egress of the batter, and finally descends to cut off the batter, which falls into a frying kettle. The movement of the sleeve and the passage of air through the pipe 14 are both controlled by a disc 41 comprising a box cam 39 and a peripheral cam 40. The cam 39 moves the sleeve by means of rocker arm 36, rod 34 and lever arm 32. The cam 40 moves a follower 43 to control a make-and-break switch 44 which energizes a solenoid 71 of which the core has an extension 97 upon which are mounted valve plungers 78 and 81 which control air pressure inlet 80 and vacuum outlet 83. The port 84 is connected to pipe 14. In a modification, the cam 40, follower 43 and switch 44 are replaced by a metal interrupter ring having an insulated segment.

Title: Improvements relating to dynamo electric machines of the heteropolar inductor type
IPC: H02K47/24
Filed: 1954-03-29
Abstract: 756,495. inductor machines. SELECTRA, Ltd., and KREBS, E. W. March 14, 1955 [March 29, 1954], No. 9185/54. Class 35. In an inductor-type motor, generator or converter having S1 stator slots and S2 rotor slots, and having mutually non-inductive stator windings wound for P1 and P2 pole-pairs respectively, the number of rotor slots S2, or the difference in the slot-numbers (S1-S2) or (S2-S1), is equal to P1+P2. As shown, the machine has twelve stator slots 11 carrying three-phase exciting and output windings 12, 13 wound for four and two poles respectively, the rotor having three slots 15. Thus S2 = P1 + P2. The machine may act as a three-phase alternator producing a frequency 3n where n is the rotor speed. If three-phase current is supplied to the exciting winding the machine acts as a frequency changer. If the machine is fed with A.C. and D.C. it will run as a synchronous motor. The functions of the two windings may be interchanged. For single-phase operation it is useful to excite the D.C. winding using two phases in parallel or across two phases with the other shorted, thus providing damping on the quadrature axis. A modification is described in which the two stator windings have the same pole numbers but are in quadrature to prevent mutual inductance. Alternatively the stator winding may comprise two separate star-connected windings whose phases are connected in parallel at the output terminals, the D.C. excitation being applied between the two star points. Other arrangements comprising tappings on a single winding are mentioned.

Title: Treatment of silicon
IPC: C30B13/14
Filed: 1959-03-18
Abstract: <PICT:0870408/III/1> Silicon is melted by induction in a non-conducting container maintained at a temperature below the melting point of silicon, e.g. 700-800 DEG C., by a non-conducting fluid coolant.  The process is carried out in a vacuum or inert atmosphere, e.g. of argon, helium, hydrogen, or reaction product gas from the production of silicon from silicon tetrachloride and hydrogen.  The non-conducting container may be of silica, alumina, mullite, p  zirconia, or thoria.  The non-conducting fluid coolant may be water, liquid nitrogen, air, or air-fluidised powdered silica. The coolant may pass through a jacketed container, or around a non-jacketed container.  Heating may be by a water-cooled copper high-frequency induction coil.  The melting-zone may be cylindrical and may have a diameter of 3/4 -3 inches or above.  The silicon may be preheated other than by induction inside or outside the non-conducting container.  An ingot of silicon may be preheated in the container to e.g. 900 DEG C. by radiation from a graphite rod heated by an induction coil to e.g. 2000 DEG C.  The graphite rod may then be replaced by particulate silicon, and the induction coil raised, after melting the initial ingot, to form a zone-refined rod. Instead of adding particulate silicon, a portion of the melted ingot may be withdrawn under vacuum into a silica tube and allowed to solidify therein.  A second ingot may be added to the residual melt, melted by induction, and a portion withdrawn as before.  The silicon may be doped.  As shown an induction coil 4 is moved up around a water-jacketed silica tube 1 to form a zone refined silicon rod 5 from an initial preheated silicon ingot and subsequently added particulate silicon 2 in an inert gas supplied through a pipe 10.
