Title: Improvements in hard metal bodies forming cutting edges in percussive rock drilling tools
IPC: C22C29/08
Filed: 1951-03-06
Abstract: A sintered hard metal insert for percussive drills consists of at least 85 per cent. of tungsten carbide or tungsten carbide and molybenum carbide, 6-10 per cent. of an auxiliary metal or alloy, e.g. iron, nickel, cobalt, copper or silver, and up to 5 per cent. of one or more further carbides or nitrides, silicides, borides, or diamond, the hard particles having a mean grain size of 2.4-6m determined on polished and etched sections.  When cobalt is used as the auxiliary metal, the larger the grain size of the hard particles the lower the cobalt content may be.

Title: Improvements in and relating to Submarine Mines.
Inventor: RILEY GERARD BROOK
IPC: F42B22/10
Filed: 1916-04-13
Abstract: 124,810. Riley, G. B., and Mock, H. O. April 13, 1916. Dash-pots.-A dash-pot for use between a submarine mine and its anchor comprises a cylinder 1 with perforations 11 exposed to the surrounding water, a piston 2 with a ball valve 12, and a spring 3. The cylinder is attached to the anchor cable by an eyelet 7; and the piston-rod 4 is attached by swivelling shackle 9 to the mine or to a short length of cable connected to the mine. The perforations 11 decrease in diameter upwards, and are spaced at progressively increasing distances apart. Before the mine is laid, the dashpot is filled with viscous liquid such as thick oil, grease, or soap; this material is extruded when the spring is first compressed by the buyancy of the mine after laying; the dash-pot then works by pumping the surrounding water in and out of it. The valve 12 may be dispensed with; the cylinder is then tapered, the upper end being of smaller diameter making a tight fit with the piston.

Abstract: 564,819. Sirens. LEAR AVIA, Inc. April 6, 1943, No. 5498. Convention date, Feb. 21, 1942. [Class 13] [Also in Group XXXIII] An aircraft is fitted with one or more sirens normally mounted so as not to add substantially to the aerodynamic resistance of the aircraft, but adapted to be exposed to the airflow when it is desired to produce sound during flight. In one form, a dive-bomber is fitted with a number of sirens 24, 25 of different pitch in the braking flaps 21 which are normally netted in recesses beneath the wings, but are turned down into the airflow during a dive. In another form, the sirens are mounted in discs having streamlined edges 55, Fig. 10, mounted on rods 57, projecting through the fuselage skin, the rods being rotatable through 90 degrees to bring the discs from a position in which they are edge-on to the airflow into the position shown. In another form, the sirens are extended and retracted through holes in the fuselage which are closed by plates carried by the siren casings 'when the latter are retracted. In another form, Fig. 9, the sirens are each mounted in the throat of a venturic passage 41 arranged just within the fuselage skin, the forward end of the passage having a hinged scoop 37 by which the passage is opened to the airflow or completely closed, a flap 38 completing the external contour of the fuselage when the scoop is withdrawn.

Abstract: 724,952. Coating wires. CONNOLLY'S (BLACKLEY], Ltd. March 2, 1953, No. 5787/53. Class 140. A wire carrying surplus coating liquid is drawn continuously upward through a wiping die comprising a chamber divided into upper and lower compartments 1 and 2 by a partition 3. The wire passes in succession through an aperture 5 which permits some coating liquid to be drawn into the compartment 2, a guide aperture 6 in the partition 3 through which the wire passes with minimum clearance, and an outlet aperture 4, smaller than aperture 5, which determines the thickness of the coating. Additional apertures 7 in the partition 3 permit coating liquid drawn by the wire into the lower compartment 2 to pass through into the upper compartment 1 which is thus kept full of coating liquid. The die is mounted in a freely pivoted bracket engaging groove 11.

Abstract: 742,600. Heating liquids electrically. GENERAL ELECTRIC CO., Ltd., and SMITH, R. Feb. 26, 1954 [March 4, 1953], No. 6023/53. Class 39(3). [Also in Group XIII] An instantaneous steam generator consists of an inner container 2 of corrosion-resisting steel covered with insulating material 4 and housed in an outer casing 1, the container 2 being three parts filled with a loosely piled mass 3 of heat storage material preferably consisting of short lengths 5 of round cast iron bar or alternatively of pieces of flint or concrete and being provided with a water inlet and drain pipe 9 and a steam outlet pipe 12. Two or more sealed tubes 6 project horizontally into the mass 3 and form pockets for electric heaters 7 e.g. one kilowatt each. In operation, the mass 3 is heated to 500‹ to 600‹C. over a period of several hours. When steam is required, water is fed to the bottom of the container through a valve 11 and flashes into steam as it contacts mass 3. As the lower bars 5 are cooled, the water level rises and water, which is preheated by the residual heat in the lower bars, is evaporated by those above. After use the water in the container is drained off through a valve 10 and the mass 3 reheated.

Abstract: 1,063,012. Automatic control of speed. SHAPE AIR DEFENCE TECHNICAL CENTRE. Feb. 13, 1964 [Feb. 14, 1963], No. 6081/64. Heading G3R. To reproduce the movements of a first shaft (not shown), e.g. that of a radar aerial, there are generated a first train of pulses indicative of shaft speed, a second train indicative of its angular position, and a third train indicative of the angular position of the reproducing disc 16, the last two trains being compared to effect an aligning operation. As shown, the two pulse trains from the first shaft have been magnetically recorded so that its movements are reproduced at a later date. The first train comprises equispaced pulses which drive a stepping motor 7 connected to the reproducing disc 16. The pulses pass through "AND" gate 1, and "OR" gate 4, the arrangement being such that, if the reproducing disc be fast the pulses are blocked at 1 and the motor temporarily stopped, while if it is slow extra pulses, obtained by passing the first train through a time delay circuit 5, are switched in by a second "AND" gate 2 and interspace with those from gate 1, thus providing a pulse doubling effect which temporarily speeds up the motor 7. The reference pulses (the second and third trains) are irregularly spaced to avoid ambiguity and are compared in a logic circuit 17. For recording on a single tape channel the two trains of transmitted pulses are merged Fig. 3 (not shown) and, after playback, separated Fig. 4 (not shown).

Title: Tunnel diode circuits
IPC: H03K17/58
Filed: 1963-02-14
Abstract: 1,021,735. Tunnel-diode bi-stable circuits. RADIO CORPORATION OF AMERICA. Feb. 14, 1963 [March 2, 1962], No. 6118/63. Heading H3T. In a bi-stable circuit comprising a tunnel diode supplied from a constant-current source or through a further tunnel diode, the load for the tunnel diode is constituted by a tunnel rectifier and the tunnel diode is so biased by a voltage source and the tunnel rectifier is so poled that the tunnel rectifier presents a load line intersecting the tunnel diode characteristic to give two stable operating points and such that the greater of the two switching-signal amplitudes required to switch the circuit from one state to the other is considerably less than would be the case if a load presenting a straight load line were used. In the circuit of Fig. 1, tunnel diode 10 may be switched between its two stable states by pulses applied through tunnel rectifiers 16, 20. The circuit is shown as coupled to monostable circuits 22, 23, 24 (comprising, for example, tunnel diode 32, constant current source 33, inductive load 36 and tunnel rectifier 35) through respective tunnel-rectifier loads 25, 26, 27. The tunnel diode 10 is supplied from a constant current source I 1  and biased by a positive voltage source V 1  so that the inverted characteristic in the third quadrant is displaced to the fourth quadrant as shown in Fig. 4, and is intersected by the inverted tunnel-rectifier characteristic 62 as shown. It will be seen that while the vertical displacement of the load line needed to switch from point 66 to point 72 is not much greater than it would be if the load line were straight, the displacement needed to switch from point 72 to point 66 is considerably reduced. In the circuit of Fig. 2 (not shown), the constant-voltage source is replaced by a further tunnel diode having a lower peak than that of tunnel diode 10; Fig. 5 (not shown), illustrates the resulting composite characteristic.
