Title: Improvements in and relating to the production and refining of metals or alloys
IPC: C22B9/00
Filed: 1937-02-19
Abstract: 496,041. Alloys; atomizing metals. FURNACE HOLDINGS, Ltd. (Buffalo Electric Furnace Corporation) Feb. 19, 1937, No. 5072. [Classes 82 (i) and 82 (ii)] An alloy containing iron is produced and simultaneously refined by forming a molten bath of metal containing an oxidizable impurity such as carbon, forming an oxidizing slag thereon and causing a finely divided metal which is to form a constituent of the alloy to impinge on the slag and pass in a dispersed and molten condition therethrough so dissolving or taking up an oxidizing reagent from the slag and transferring it to the metal bath to oxidize the impurity therein. An alloying metal 17, Fig. 1, fed through hollow electrodes 11, which may be rotated by means of gears 12, is formed into drops 18 or vapour by the arc and passes into an oxidizing slag 16 on a metal bath 15. Correctives 19 for adjusting the viscosity or permeability of the slag may be added thereto. In another form, Fig. 2, the alloying metal is more finely divided by passing a stream 26 of molten material through the bore 21 of a fitting 20 to which high pressure gas, e.g. steam, is fed, the gas issuing through the annular nozzle 24. In another form, a single vertical or inclined hollow electrode is employed, mounted above the slag layer. The metal rod or wire fed thereto may be coated with inert materials or with non-oxidizing materials required for the slag. As a further alternative, comminuted metal may be added mechanically, e.g. by shovelling. Comminuted carbon, silicon or silicides may be added with the alloying metal. The process may be employed for the decarburization of iron-chromium or iron-nickel alloys or ferro-manganese. Silicon and manganese may be removed, when necessary, by a preliminary deslagging. The process may be carried out in an atmosphere of carbon monoxide. Specification 472,038 is referred to.

Title: Improvements in or relating to circuits embodying passive-impedance quadripoles
IPC: H03H11/42
Filed: 1952-02-27
Abstract: 747,012. Impedance networks. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Feb. 27, 1952 [March 1, 1951], No. 5160/52. Class 40 (8). In order to obtain maximum transfer impedance two amplifying valves are connected by a passive impedance network 3 which includes a " gyrator," i.e. a quadripole circuit having unequal transfer impedances Z 12 , Z 21 . Such non- reciprocal quadripoles may have forward and backward transfer impedances whose moduli are equal but which have different signs. The following relations thus exist between the input and output currents and voltages s being the "gyration conductance." Gyrators are described in Specifications 645,905 and 716,257. Assuming that the transfer impedance is given as a prescribed function of frequency it is required that it should have a maximum possible modulus for given values of the capacities c 1 , c 2  which may be stray capacities or inter-electrode capacities. This problem is solved by Bode (Network Analysis and Feedback Amplifier Design, Ch. XVII) for an ordinary reciprocal network and it is shown that a network fulfilling the condition stated is theoretically required to be of an infinitely high class. In the Specification, Bode's method is applied to networks comprising gyrators and it is found that the condition for maximum transfer impedance is where the Rem and Xem are the real and imaginary parts of Zem. In contradistinction to the case of reciprocal networks where the right-hand side reduces to -R 21 - the quantity under the root sign now comprises the sum of two squares so that it may form the square of a positive rational function P of w<SP>2</SP> so that In this case the network becomes of finite class, since R 11 , R 22  must be capable of being expressed as the quotients of pairs of polynomials. It is shown in the Specification that a network has maximum transfer impedance Z 21  when where b 1 , b 2  ... are positive real constants or pairs of conjugate complex constants having positive real parts, Z(jw)=Z(-jw), and p stands for jw. A network in which Z 21  and Z 12  fulfil this condition also fulfils the other conditions so that it remains of finite class. As an example, the transfer impedance may be given by the equation The impedances Z 11  and Z 22  can then be worked out. The network can be constructed in the manner shown in Fig. 5 by making c 1 =c 2 , the gyrator being indicated by a pair of semicircles and a resistance R being shown as connected between one input and one output terminal of the gyrator. The values are The transfer impedance is several times greater than that obtained with a reciprocal network of finite class. The Specification gives several other examples.

Title: Machines for forming cones of pastry or like material
IPC: A21C11/16
Filed: 1951-03-03
Abstract: 703,004. Making pastry cones &c. BENTLEY, F. J., and BENTLEY, A. E. June 3, 1952 [March 3, 1951], No. 5200/51. Class 87 (2) A baking cone 34 is rotated by a holder 10 fixed to a horizontal or inclined shaft 11 driven by an electric motor 15. One or more projections 35 engage with one or more helical grooves 32 on the holder and the direction of rotation is such that during winding on of the pastry the grooves tend to force the cone on to the holder. A pastry guide comprising two rollers 55, 56, one of which dips into a water tank 62, is supported on a shaft 22 having a half-nut 19 engaging with a screw-thread on the shaft 11. In operation, a main switch 28 is closed, a cone fitted to the holder, and a switch 27 closed to start the motor to cause the pastry guide to move to the right (as shown) and the cone to rotate. A strip of pastry is fed to the rollers 55, 56 and wound on to the cone. When a collar 39 on the shaft 22 hits a bracket 13, movement of the shaft is stopped, but the block 21 carrying the half-nut 19 continues to move until a member 43 actuates a switch 25 to reverse the motor 15. The shaft 22 then moves to the left until the member 43 actuates a switch 24 to reverse the motor 15 and cause shaft 22 to move to the right again. During this leftward movement the cone is manually removed from the holder, the reversal of rotation of the shaft 11 assisting removal. When the shaft reaches its initial position a striker 53 on a bell-crank lever 45 actuates a switch 26 to stop the motor. During the leftward movement of the shaft 22 the bell-crank is moved by an abutment 51 to raise the striker above the switch, the striker being moved back again by an abutment 49. The next cycle is then started by closing the switch 27 again.

Abstract: 688,533. Gear-finishing machines. NATIONAL BROACH & MACHINE CO. March 1, 1949 [April 12, 1948], No. 5596/49. Class 83 (iii). [Also in Group XXX] A loading fixture for a gear-finishing machine comprises a loader 12 which supports a work gear W for rotation and is movable to advance the gear tangentially into mesh with a gearlike tool T, and brake means 51 to resist rotation of the work and assist meshing. Workgears W, having shafts S, are contained freely in a shoot 80, the lowest gear resting on a member 41 screwed to the loader 12. To the member 41 is pivoted at 45 a holder 40 which itself carries twin brake arms 51 pivoted at 54, the braking pressure being obtained by a spring 59. Initially, the loader 12 is retracted by a pneumatic device 25, causing a stop 85 to rotate an arm 61 against the pressure of the spring 59 and allow a gear to drop into a recess 49. The loader is then advanced to mesh the gear and tool until movement is stopped by the abutment of a member 15 with a stop 23 and a switch 38 is actuated to advance centres to grip the gear. Any resistance to meshing is taken up by a spring 46 and positioning of the gear is assisted by jaws 90. The loader is then withdrawn and a switch 39 is actuated to initiate rotation of the tool and relative traverse between the gear and tool. When the gear is finished the centres are retracted, the gear falls on to discharge rails 98 and the loader is again advanced. If correct positioning is not obtained, further automatic operation of the machine ceases. The rails have a diagonal break adjacent a support 99 to prevent cutting oil leaving the machine. The fixture is attached at 97 to a gear lapping or shaving machine. In a modification, gears W<SP>1</SP>, Fig. 6, without shafts, are moved by a hydraulicallyoperated slide 110 and braked by a member 115. On retraction of the slide, the brake is released by a pin 130 and a stop 126 is cammed upwardly to retain the remaining blanks in the shoot 125.

Title: Float operated liquid level indicator
IPC: G01F23/66
Filed: 1959-02-19
Abstract: 878,190. Indicating liquid levels. MEDINGER, VON W. Feb. 19, 1959 [Feb. 19, 1958], No. 5779/59. Class 123(1) A liquid level indicator comprises a float 1 containing a magnet 3 and slidably mounted on a closed tube 2 disposed vertically in the liquid container, an armature 4 which follows the movements of the magnet being disposed within the tube. The armature movements are transmitted by a chain 7 to a pulley 9 carrying a level indicating pointer 8, the chain passing over the pulley and being connected to a counterweight 10. To prevent the chain becoming jammed in the tube 2 if the float is lifted quickly, for example when the container is being cleaned, the chain is not connected positively to the armature but passes through a hole 6 therein and is connected to a weight 11 upon which the armature normally rests. If the float is lifted quickly the armature is raised from the weight 11 which continues to hold the chain taut and prevent jamming whilst the counterweight acts to wind the chain over the pulley until the weight 11 again comes into contact with the armature. In a modification a resistance thermometer is housed within the tube 2.
