Nov. 11, J930, No. 33977. Convention date, Nov. 12, 1929. [Class 53.] The elements of a thermocouple consist of tantalum carbide and graphite. The Figure shows a couple in which the graphite element is in the form of a tube 1 within which is a wire 2 of tantalum carbide, the end 3 forming the hot junction. An insulating spacer 4 of thoria or zirconia may be inserted in the open end of the tube which may be kept cool by water flowing through several turns of copper tubing 5. Connection to the graphite tube may be made through the medium of the tubing 5 as shown at 6.

Title: Method of producing centrifugal cast hollow bodies, in particular of steel
IPC: B22D13/10
Filed: 1936-12-10
Abstract: 469,368. Making pipes. BUDERUS' SCHE EISENWERKE. Dec. 10, 1936, No. 34004. Convention date, Dec. 10, 1935. [Classes 83 (i) and 83 (ii)] Casting composite articles.-Before casting a steel pipe &c. in a centrifugal mould a thin layer of a metal of lower melting point, such as iron, is poured in. As the iron layer, though wholly or partly solid, is at a high temperature it becomes fused to the steel and the outer layer of steel can shrink without stress. The inside of the steel casting may be cooled by gas from a set of radial nozzles moved longitudinally. The casting may be annealed and the outer layer may be machined away. One trough, two separate troughs, or a divided trough arranged to pour tangentially and heated ladles may be used. Although sand lined moulds may be used water-cooled chills are preferred.

Abstract: 499,429. Venturi and Pitot tubes for aircraft. WALLIS, H. C. Dec. 13, 1937, No. 34430. [Class 69 (i)] To prevent the entry of dust, water, and other foreign matter into a Venturi or Pitot tube 10 used on an aircraft, a movable closure 18 is provided for the air-reception end which tends to move to closing position and is controlled in accordance with the air-speed so that when this is above a predetermined limit it moves to the open position. In the construction shown, the closure 18 is formed at one end of a lever pivoted to a clamp 11 secured to the tube 10, the other end 16 of the lever being formed as an aerofoil which, on the predetermined speed being attained, causes the lever to rock and lower the closure 18 from the mouth of the tube.

Abstract: 380,313. Rotary pumps. EKELOF, J., Liding÷, Sweden. Dec. 11, 1931, No. 34437. [Class 110 (ii).] Fixed-abutment type.-A gyratory annular piston 5, Figs. 1 and 2, of a rotary pump or compressor is mounted so as to be capable of free axial and radial movements, within limits, within an annular cylinder 5<1> provided with a radial transverse wall 16 and having a cover disc 6 which forms part of the piston structure and which is maintained against one end face of the cylinder by fluid pressure acting on its outer face 14. This arrangement permits close contact between the piston and cylinder walls to be effected by centrifugal force and permits the pump to be coupled direct to an electric driving motor, means such as springs being provided to relieve the centrifugal force, if necessary. The piston 5 and cover disc 6 may be rotatably mounted on a boss 9 capable of sliding axially and radially on a driving crank pin 7 in a plane through the axes of the piston 5 and driving shaft 7<1> and one of the lines of contact between piston and cylinder wall. An abutment on the boss 9 may engage a pin or other means on the driving shaft 7 to limit its angular movement relatively to the crank to prevent the piston assuming such a position as to effect the efficiency of the pump. The boss may alternatively be mounted eccentrically and rotatably on a driving crank pin coaxial with the piston 5.

Hot granular material discharged from flash roasters, sintering machines or cyclone furnaces, is cooled during passage down a vibratory, helical, stepped grate 2 supplied with air from a fan 6 through a central tube 4 and ports 7 opening below the grate steps. The latter have forward slots with ports on one or both surfaces, Figs. 4-7 (not shown), and the central tube is vibrated. The steps are disposed on a helical floor 8, parallel to which is a deflecting plate 9 channelling the cooling air, with an adjustable member 9a controlling the gap between the plate 9 and the tube 4. Spent air escapes via a cyclone separator 11 and an offtake 12, and cooled material is discharged through a shoot 5. In a modification, Figs. 8 and 9 (not shown), the cooler forms part of a sinter plant, and is preceded by a rotary classifier and a screen. Hot sinter is separated into fines below a grain size of 10-30 mm., which are cooled as above, and coarse material cooled on a conventional moving grate. Preferably the cut between the screened fractions is made at 10-12 mm. grain size. The fine material is returned to the feed end of the sinter plant.

Title: Improvements in and relating to metal surfaces
Inventor: WELSH NORMAN CLIFFORD
IPC: B23K11/00
Filed: 1956-11-14
Abstract: A method of treating an electrically conductive surface comprises using an electro-sparking process for adding one or more substances to the material of this surface, wherein one or more of the substances to be added are in powder form.  By the term "electro-sparking" is meant a plurality of discharges of electric energy of very short duration occurring simultaneously with each other and also in succession between an electrode and the conductive surface to be treated which forms the other electrode, the spark being produced in a medium which may be liquid or if gaseous is at atmospheric pressure.  The powder may be suspended in a gas, liquid, or paste, or it may form part of a sparking electrode in the form of a metal graphite compact or it may be in the form of a tube containing the powder.  The powder may be one or a combination of high melting point metals such as chromium, tungsten, tantalum, which may also combine chemically with the graphite of the electrode to form a carbide on the surface being treated.  The powder may be dispersed in a carbonaceous carrier such as wax, grease or mineral oil.  When the work piece is steel, a hard carbide layer may be formed on its surface.  Specification 749,486 is referred to.

Abstract: 1,108,863. Railway buffers. GODWIN WARREN ENGINEERING Ltd. 12 Aug., 1966 [13 Aug., 1965], No. 34823/65. Heading B7L. A retractable buffer stop assembly for arresting vehicles, e.g. mine cars, moving in a downhill direction along track rails, comprises a buffer stop 1, Fig. 1, slidably mounted on a pair of rail sections 7, the latter and the stop 1 forming part of a pivotal unit movable from an inoperative position (within a pit 14 below the track) in which the stop 1 is clear of vehicles passing along the track, to an operative position (shown in full lines) in which the rail sections 7 are aligned end-to-end with fixed ancillary rails 10 positioned between and parallel to the track rails (not shown), the rails 10 having brake shoes 15 frictionally engaging therewith as described with reference to Fig. 3 (not shown), and in which position the stop 1 is engageable by an out-of-control vehicle moving in the downhill direction so as to be moved along the sections 7 and on to the rails 10 where the shoes 15 coact with the stop 1 to arrest the vehicle motion. The stop 1 comprises a pair of spaced trestles 3, each carrying a buffer plate 2 and having a slide 4 with guides 5 engaging a rail section 7, the trestles being connected by a roller 20 over which a mine car haulage cable runs. The sections 7 are mounted on a platform 9 having supports 9a pivoted at 12 to the rails 10, the pivotal unit having a counterweight 11 which biases the unit to the operative position. The stop unit is movable to the inoperative position in the pit by an air or hydraulic cylinder 13 and retained therein by a catch 21. The latter is releasable when necessary by remotely controlled hydraulic or pneumatic means. The stop unit is normally in the operative position so that mine cars moving up the inclined track, strike the trestles and deflect the unit, which thereafter returns to the operative position by the influence of the counterweight. In another embodiment, the buffer stop unit is provided with a buffer beam connecting the trestles and the roller is dispensed with. The unit is normally retained inoperative by the catch which is releasable automatically by a signal received from a detecting device, e.g. a vehicle speed detector.
