Title: Improvements in or relating to trimming machines for use in operating on shoes
IPC: A43D53/00
Filed: 1955-10-08
Abstract: 798,311. Shoe trimming machines. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). Oct. 8; 1956 [Oct. 8, 1955], No. 28724/55. Class 17(1) An inseam trimming machine has work feeding means, a rotary cutter 32 with a plurality of cutting blades 110 each having two cutting edges, a shearing edge to co-operate with one cutting edge and another shearing edge to co-operate with the other shearing edge, the arrangement being such that surplus material is cut off in small pieces. The first cutting edge lies parallel with the length of the inseam and co-operates with a rotary shear member 34, and the second cutting edge is substantially perpendicular to the first edge and co-operates with a fixed shear member 36. The shoe is located heightwise and laterally by engagement of rotor 22 in the inside channel 24 of the insole 12, and with the insole ribs 10, and is supported by a presser roll 28 engaged 'between the welt 20 and upper 16. Roll 28 is adjustable heightwise by means of an abutment screw 41 which determines the position of lever 35 and hence of lever 31 which carries the roll. Spring 43 normally engages the roll with the work, but on depression of the treadle a collar on the rod thereof swings lever 35 to lower the roll. Rotary shear member 34 is of tubular form with a flared upper end terminating in a frusto conical portion having an inner shearing edge 38, and outer teeth 40 to engage the welt and co-operate with rotor 22 to feed the work. To provide access to the cutter, rotor 22 with 80, 82, 88, may be swung forwardly and upwardly on arm 90, which may be held in any one of three positions by a pin 102 on arm 168 engaging in one of three holes 104 in a flange extending from the arm. The speed of cutter 32 is regulated in accordance with the number of blades it carries. Cutter 32 is adjustable horizontally and heightwise relatively to shear member 34 and shear block 36. Fan 160 acts via duct 162 and funnel 164 to remove the small separated chips. Specification 112,808 [Class 17 (i)] is referred to.

Title: Means for suppressing disturbances in ionic valves by grid-control
IPC: H02H7/127
Filed: 1935-10-18
Abstract: 464,765. Converting. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Oct. 18, 1935, No. 28811. Convention date, Oct. 22, 1934. [Class 38 (ii)] In a valve converter system in which the neutral of the grid transformer is either disconnected from the cathode or is connected thereto through a high resistance, provision is made whereby in the event of faults such as back ignitions, the voltage of the grid transformer is reduced and a voltage is applied between the cathode and grid transformer which renders the grids negative with respect to the cathode. The primaries 6 of the grid transformer are connected between the phase windings 4 of the main transformer associated with the anodes 2 and the neutral of the interphase transformer 5. The secondaries 8 are in two star-connected groups the neutrals of which are connected through high resistances 9 to the cathode 1. Across a part of the resistances 9 is connected a condenser 10 or other voltage source tending to maintain the grids negative with respect to the cathode. In the event of a fault causing a drop in voltage in the main transformer windings 4 and consequently a reduction of the grid transformer voltage, the voltage of the condenser 10 or other source which operates on a low resistance path through auxiliary rectifiers 11 is effective to maintain the grids negative. Moreover, the resulting change in current in the grid circuit causes operation of a relay 12 which is effective to short-circuit or otherwise de-energize the grid transformer (e.g. by saturating it) until the relay is reset either by hand or automatically after a time period sufficient for restoration of normal operation. Specification 412,773 is referred to.

Title: Improvements in grain cleaning machines
IPC: B07B7/08
Filed: 1922-10-25
Abstract: 206,346. Bentham, C., and Simon, Ltd., H. Oct. 25, 1922. Pneumatic separating.-In apparatus for cleaning grain by means of a current of air moving in a closed cycle, the air after passing through the grain is divided into two parts, the major part which is comparatively free from dust passing back direct to the stream of grain, and the smaller part which is heavily laden with dust passing first through dust depositing chambers and then joining the main current of air. In one construction, Fig. 1, the grain is fed through a pipe a to a centrifugal disc b and is subjected to a stream of air induced by fans g, k. The rotary movement imparted to the air causes the major portion of the dust to accumulate at the periphery and to be discharged with a small amount of air into a cyclone separator i where it deposits and is removed by any suitable device j. The major portion of the air comparatively free from dust is driven by the fan through the passage m to pass again through the grain and is joined by the air from the cyclone separator. The hopper e collects the heavier impurities from the grain. In a modification, the portion of air heavily laden with dust is first cleaned by passing through a settling chamber and a cyclone separator and is then passed through the stream of grain at a point after it has been subjected to the action of the main portion of the air from the fan k. Another modification is shown in Fig. 2, in which the fan g delivers the air into a passage h, curved at h' and provided with traps n, o which take the heavily charged air to a cyclone separator i. The main body of the air passes direct to the stream of grain and the air from the separator i is driven to the same point bv the fan k.

Abstract: 1,138,167. Toolholders. WARNER & SWASEY CO. 29 June, 1966 [30 June, 1965], No. 29113/66. Heading B3B. Means for securing and clamping a toolholder 40 to a turret 15 of a machine tool comprises wedge members 61, 62 positioned, one at each end, in the base of the toolholder which is shaped so as to be insertable in a slide 30-34 in the turret. The wedge members co-operate with tapered surfaces in the base of the toolholder and are movable by a threaded rod member 70 having a left and a right-hand thread at each end so that rotation of the rod causes movement of the wedges towards and away from each other in the direction of the axis of the rod. When the toolholder is positioned in the turret slide, the rod is rotated to effect clamping of the holder. Stop means 80 and 85 are provided for each wedge to limit the displacement thereof between predetermined limits.

Title: Process for the production of methane
IPC: C07C1/04
Filed: 1925-11-19
Abstract: Methane is prepared by the interaction of carbon monoxide and hydrogen-containing gases at atmospheric pressure over a nickel catalyst maintained at a temperature above 500 DEG  C.  To permit of the use of this temperature, which is substantially higher than that usually employed, the rate of flow of the gas mixture is adjusted to ensure rapid removal of the product from the reaction zone.  The gases may be passed over one or more catalysts arranged in series, or the process may be operated cyclically.  Examples are given.  The Specification as open to inspection under Sect. 91 (3) (a) states that the reaction may be carried out at a temperature of 400 DEG  C. or above.  This subject-matter does not appear in the Specification as accepted.

Abstract: 520,036. Wireless receiving apparatus. THORNTON, A. A. (Philco Radio & Television Corporation). Oct. 11, 1938, No. 29425. [Class 40 (v)] A mains energized receiver for either AC or DC and for either 120 or 240 volts has a resistance R6 in circuit with the anodes and screen grids of certain valves, whilst the anodes of the I.F. pentode amplifier 5 and of the pushpull pentode output amplifiers 8, 9 are supplied from the input side of the resistance R6. When used on 120 volts supply the resistance R6 is shorted by a plug switch 13, whilst when used on 240 volts supply the resistance is effective to drop the voltage to the same value or even slightly less than when used on 240 volt supply. The slight reduction is to reduce the screen grid voltage of the pentodes to compensate for the doubled anode voltage thereon. The switch 13 is also used to short part of the ballast resistance 12 in circuit with the cathode heaters 11.
