Filed: 1974-01-25
Abstract: 1417825 Pipe couplings RIKEN SEIKI KK and RIKEN KIKI KK 25 Jan 1974 03607/74 Heading F2G In, e.g. tunneling apparatus utilizing an ultra high pressure jet of water to disentegrate bedrock, the fluid pressure in a rotary coupling acts on the end of a plunger 13 to force relatively rotatable end faces 19, 20 into butting and sealing engagement. The plunger 13 is rotated with the member 3 by dog clutch 27, 31. The rotation may be effected by a pulley 4. Contact pieces 16 and 9 are replaceable but may, alternatively, be formed integrally with the plunger and member 2, respectively.

Title: Improvements in or relating to stranding machines for textile material
IPC: D01H1/00
Filed: 1921-01-31
Abstract: 182,502. Piquet, J. Jan. 31, 1921. Spinning and twisting machines with twisting arrangements at delivery; winding-machines; spindle apparatus; thread guides; stop-motions. -Relates to machines for twisting and stranding twisted or untwisted threads of textile material of the kind in which a number of bobbins are rotated by frictional contact of pulleys thereon with an annulus or ring, and consists in driving the ring at variable speeds in either direction. As shown, the bobbins 1, Fig. 1, are mounted in carriers rotatable in spider frames 3, 4 on a driven central spindle 5, the bobbins being rotated about their axes by the frictional engagement of discs 11 on the carriers with a driven annulus 10, which is loose on the spindle and is driven by a belt from a multi-grooved pulley 31 geared by a second belt to a multigrooved pulley 7 fast on the spindle. The disc 11 of each carrier is connected by supports 13, Fig. 3 with a grooved disc 12, all the discs 12 being connected by a driving-belt to ensure equal rotation of the bobbins and to counteract the effect of centrifugal force. A spring-pressed plate 18 bears on each bobbin, and the thread is passed around the supports 13, beneath a pulley 21 on a spring-controlled plate 16, over a pulley 23, and around double pulleys 24, 25 to a pulley 26, and thence to a tubular member 28 and a sleeve 32. The double pulleys, 24, 25 are secured to worm-wheels 34, 35 in mesh with a worm 33 fast on the spider 3, so that rotation of the carrier draws the thread from its bobbin. The threads from the sleeves 32 pass to a guide-eye 30 on the spider 5, where they are twisted together, the resulting cord passing over a pulley 46 and a multi-grooved driven pulley 39 slidable on a sleeve on a shaft 36 to a belt-driven winding- on bobbin 41. When the bobbin 1 becomes exhausted, or if its thread breaks, the corresponding plate 16 is forced down by its spring, and a projection 52 on the plate comes into contact with the upper rim of the annulus 10. A finger 51 is secured to a rod 48 carrying the belt fork 47 and rest normally on the annulus. When the finger is engaged by the projection 52, the rod 43 falls and the belt is moved on to the loose pulley 9 to stop the machine.

Abstract: 345,033. Infusers. STOTT & CO. (ENGINEERS), Ltd., J. and SCHOFIELD, L., Lee Street, Oldham. Feb. 4, 1930, No. 3747. [Class 129.] Apparatus for infusing beverages comprises two chambers, one above the other, the upper containing the beverage and the lower the water, and a controlled method of transferring the hot water to the beverage. In the form shown, water is placed in the container 2 and coffee or tea &c. in the strainer 6 in the container 3. As the gas burner 15 heats the water, the ball float 7 rises causing the block 8 to close the hole 4 at the base of the container 3. The boiling water then rises in the container 2 and pours through the holes 5 on to the coffee. At the same time water enters the pipe 9, flows into the pipe 10 and lifts the float 12 of the thermostat 11 in the gas supply pipe 14 and regulates the gas supply. The strainer 6 may be dispensed with.

Title: Method of producing magnesium alloys with high creep resistance at elevated temperatures
IPC: C22F1/06
Filed: 1960-02-09
Abstract: 885,127. Working at specified temperatures; altering physical properties. FUCHS, H. J. Feb. 9, 1960 [Feb. 9, 1959], No. 4599/60. Drawings to Specification. Class 83 (4). A method of producing a workpiece from a magnesium alloy, said workpiece having high strength at room temperature and high creep resistance at elevated temperatures is characterized in that the workpiece is formed by a non-cutting process, e.g. extrusion or hot forming, above the recrystallization temperature of the alloy, is critically formed below the recrystallization temperature and is subsequently heat-treated at temperatures above the recrystallization temperature. In an example, a bar of 19 mm. diameter is extruded at 340‹ C. from a magnesium alloy containing 6.6% aluminium, 0.81% zinc and 0.13% manganese to produce a mean grain diameter of 0.019 mm. After cold stretching the bar to effect an elongation of 0.8%, then heating for 24 hours at 400‹ C. and subsequently quenching in water the mean grain diameter of the bar increased to 0.35 mm. In another example, a bar of 19 mm. is extruded at 330‹ C. from a cast block of a magnesium alloy containing 2.8% aluminium, 0.72% zinc and 0.14% manganese. The bar is cold stretched to give an elongation of 1.3%, then heated at 450‹ C. for 90 minutes and quenched in water to produce a bar having a mean grain size of 0.57 mm.

Title: Improvements in and relating to the manufacture of ferrochromium alloys
IPC: C21C5/28
Filed: 1922-02-16
Abstract: 197,733. Wild, R., and Wild, A. H. Feb. 16, 1922. Alloys.-In a process for the production of alloys containing iron and chromium, such as ferro-chrome or unstainable iron or steel of the type in which molten alloy containing oxidizable impurities is subjected to an oxidizing blow, the blow is performed in the presence of an element, such as manganese, which is more readily oxidizable than chromium, for the purpose of reducing the loss of chromium during the blow. In the case of alloys of the' type of unstainable iron or steel, the proportion of manganese is not less than about 2 per cent, or not less than about two-thirds of the oxidizable impurities; in the case of ferro-chrome, the proportion of manganese may be lower. The manganese may be introduced during the manufacture of the crude alloy by effecting the reduction in the presence of manganese or of a reducible compound thereof, or by using silico-manganese as the reducing-agent; or the manganese may be added, for example as ferro-manganese, to the already prepared alloy. The reduction of the chromium compound may be effected in a molten bath of carbon-free or low-carbon iron or steel, or ferro-chrome may be added to the molten iron or steel, the product in either case being blown under the above-described conditions; or ferro-chrome blown under these conditions may be added to iron or steel. The reduction-mixture may be used in the form of briquettes. The blast may be delivered to the metal through a wrought-iron pipe covered with fire-clay and it may carry in reagents such as chromite, or lime.

Title: Improvements relating to the synchronisation of saw-tooth wave generators
IPC: H04N5/12
Filed: 1948-02-18
Abstract: 643,911. Automatic frequency control systems. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Feb. 18, 1948, No. 4769. Convention date, Nov. 29, 1946. [Class 38 (iv)] [Also in Group XL (b)] A sawtooth generator is synchronized by periodic pulses such as are received from a television transmitter by applying the pulses directly to a free-running multivibrator, and by also applying them indirectly through a phase-sensitive system, the multi-vibrator being used' to trigger the sawtooth generator. As shown, the line synchronizing pulses derived from the pulse separator 6 of a television receiver are fed directly by a condenser 9 to the pulse-generating multi-vibrator 10 which is thereby rapidly brought into loose synchronism during the starting period. The pulse generator 10 controls the line frequency sweep generator 7 for the C.R. tube 4, and also controls an auxiliary sawtooth generator 33. The incoming pulses from 6 are fed through a cathode-follower valve 51 and transformer 42 across one diagonal of a diode bridge detector 35 in series with a biassing condenser-shunted resistor 40. Across the other diagonal of the bridge the output from the sawtooth source 33 is applied in series with an output resistanceshunted condenser 39. The voltage across the condenser 39 varies according to the phase difference between the incoming pulses and the sawtooth voltage, and is applied to a valve 26 functioning as a variable resistance in the grid-earth connections of the multi-vibrator 10, and adjusting its frequency so as to set up and maintain phase agreement with the incoming pulses. In a modified circuit (Fig. 3, not shown), the multi-vibrator 10 operates at a multiple of the incoming pulse frequency. It feeds a second multi-vibrator which operates at the pulse frequency and controls the sawtooth generator 33.
