Title: A method of tin coating ferrous metals
IPC: C23C2/08
Filed: 1940-03-29
Abstract: 539,166. Coating metals. THORNTON, A. A. (Cleveland Graphite Bronze Co.). March 29, 1940, No. 5699. [Class 82 (ii)] . A method of coating ferrous metals such as iron or steel with tin comprises heating the metal in a non-oxidizing, reducing, or de-carburizing atmosphere to a temperature at or above the critical temperature of gamma iron formation, e.g. 1337‹ F., and then passing it, without contact with air, through molten tin. In the apparatus shown a steel strip 1 is passed through a tubular furnace 2 through which hydrogen or other gas is passed. The lower end of the furnace 2 is submerged in a bath of molten tin 6 which may be at a temperature between the melting point of tin and 1200‹ F., e.g. 500‹ F.

Title: Method for making zirconium boride
IPC: C01B35/04
Filed: 1961-02-16
Abstract: Zirconium boride is prepared by reacting at or approaching arc furnace temperatures a mixture comprising zircon (ZrSiO4), carbon, and a compound which is a source of and which contains boric oxide. The boric oxide source may be boric oxide itself, borax, colemanite, ulexite or kernite, and the carbon feed may be in the form of coal, coke, or graphite.  The mixture may comprise 40-70% by weight zircon, 15-35% by weight carbon, and sufficient boric oxide source to provide 15-35% by weight boric oxide, or the materials may be in stoichiometric proportions, or alternatively the mixture may comprise 40-60% by weight zircon, 15-25% by weight carbon, and sufficient boric oxide source to provide a stoichiometric excess of boric oxide. The reaction may be carried out in an arc furnace, and the feed to the furnace may include unreacted mixture from a previous batch.  Any hafnium present in the zircon is converted to hafnium boride during the reaction.

Filed: 1948-02-26
Abstract: 652,885. Temperature-responsive actuating-elements. ROBERTSHAW - FULTON CONTROLS CO. Feb. 26, 1948, No. 5752. Convention date, April 4, 1947. [Class 64(ii)] [Also in Group XXIX] A temperature-responsive element actuating a valve 56 controlling the flow of either a heating or a cooling fluid comprises a bellows 48 enclosing a chamber connected by rigid or flexible tubes 81, 85 to a bulb 82, which is exposed to the temperature to be controlled, and to a chamber in a device for manual adjustment of the temperature at which the valve is actuated. This adjustment is obtained by rotating a knob 97 thus moving a cylinder 108 to alter the volume of a chamber 107 which is open to the fluid from the thermostat 82. Should the temperature of this fluid increase when the valve member is seated, the pressure in the chamber 107 will increase and cause the cylinder 108 to rise against a spring 110, so protecting the bellows 52 from damage. The bulb 82 is finned and has at its end a threaded stud 84 by which it can be mounted.

Title: Improvements in and connected with apparatus for indicating the speed and direction of movement of engines or machines
IPC: G08B9/00

Abstract: 395,444. Speed and direction indicators. CHADBURN'S (SHIP) TELEGRAPH CO., Ltd. and BAMFORD, A. C., Cyprus Road, Bootle, Lancashire. Feb. 27, 1932, No. 5888. [Class 106 (iii).] Indicating visibly at a distance.-An engine or other speed-indicator of the periodic counter type as described in Specification 1989/15, [Class 106 (iii), Fares &c.], is associated with a main indicating instrument mechanically operated and a sub-indicating instrument electrically operated for indicating at a distance the speed and the direction of rotation. Fig. 1 shows the speed and direction indicating mechanism and Fig. 3 a wiring diagram of the system. The shaft 4 connected to the engine may be rotated in either direction, but rotates the gear wheel 8 on the main speedometer shaft always in the same direction. The wheel 8 drives the counting pointer 1, which forms part of the main indicating instrument for definite intervals of time through the clutch 8<x> operated by clock mechanism. The pointer 1 moves from zero to various positions and back to zero for each period of time. It controls the position of the sentinel pointer 2 which indicates the number of revolutions counted during the last period. The pointer 2 carries a contact 9 which moves over a coiled wire rheostat 10, thus varying the resistance in the circuit of the sub-indicating instrument 13 and adjusting the pointer 14 correspondingly to the pointer 2. The driving shaft 4 also operates a direction indicator 3 in the main indicator through a friction member 25 which also connects the contact 20 to the contact 19 when rotation takes place in one direction, thereby closing a circuit through the coil 18 in the indicator 13 so that the end of the lever 16 is pulled downwards and the " astern " indication given. The " ahead " indication is given when the coil is de-energized during reverse rotation of the shaft 14.

Abstract: 511,954. Semi-rotary compressors. NATIONAL GAS & OIL ENGINE CO., Ltd., BALMFORD, A. B., and BURN, W. S. Feb. 25, 1938, No. 6007. [Class 110 (ii)] A compressor for supplying scavenging or supercharging air to an internal-combustion engine comprises an oscillating member 9 having radial pistons 6, 7, which co-operate with valve members alternately cutting off suction and delivery ports 10, 11. An abutment 8 has pockets 23 communicating with ports 10, 11 controlled by oscillating plates 12 which alternately open and close suction and delivery ports. The member 9 and valves 12 may be driven from the engine crank-shaft by separate crank mechanisms, Air enters a chamber 19 through a filter 20, and passes by way of passages 21 and parts 11 through the suction ports to the chamber 3, and is delivered through similar ports 11 to a receiver 13 which communicates periodically with the engine cylinder or cylinders. The member 9 and valves 12 may be made of a light alloy with thin discs 24 of a different material separating them. The capacity of the chamber 3 may be increased axially by inserting a longer member 1 between the end walls 3, 4. In place of the valves 12, reed valves of single strip or multiple form may be attached at the inner end of the abutment which is divided centrally to form two compartments connected to suction and discharge passages respectively. In a further arrangement a single piston on the member 9 has reed valves in its surface closed during a compression stroke and opened by inertia effort on a return stroke.

Abstract: 1,019,621. Ultrasonic viewing devices; television. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Feb. 21, 1962 [Feb. 21, 1961], No. 6272/61. Headings H4D and H4F. Relates to apparatus in which an image of the point - by - point ultrasonic transmission characteristics of an object 4 immersed in liquid in a tank 3 and illuminated obliquely by an ultrasonic transmitter 1 is produced by focusing the waves passing through the object 4 on to the piezo-electric transducer plate 6 of an ultrasonic camera tube 7 whose output from an electrode 12 is applied to intensity modulate a display tube 14 scanned synchronously with the camera tube 7. If the object 4 is so large that the image on the transducer plate 6 corresponds to a portion only of the object 4 then in accordance with the present invention a displayed image on the tube 14 corresponding to the whole of the object 4 is produced by adjusting the amplitudes of the scanning waveforms for the display tube 14 so that the resultant raster covers only a small portion of the screen 15, cyclically moving the object 4 or the camera tube 7 in a plane parallel to the transducer plate 6 and cyclically displacing the raster on the display tube 14 in accordance with the movement of the object 4 or tube 7. As shown, vertical and horizontal movement of the object 4 is produced by rack-and-pinions 16, 17 and 19, 20 ganged to respective display shift potentiometers 18 and 21. The movement of the object 4 may be such as to effect a rectangular scan of vertically displaced horizontal lines or horizontally displaced vertical lines; in the latter case the vertical scanning of tubes 7 and 14 may be rendered inoperative. A record of the complete display may be produced by photographing the screen 15, the camera shutter being closed or the display being blanked during the retrace periods of the mechanical scanning; alternatively the tube 14 may comprise a direct viewing storage tube. The output from the ultrasonic transmitter 1 may be controlled automatically by a mean rectified output signal from the camera tube 7 to maintain the average ultrasonic power incident on the transducer plate 6 within predetermined limits.
