Filed: 1945-03-02
Abstract: 611,036. Boring earth and rock. DUFFIELD, C. F. March 2, 1945, No. 5207. Convention date, Aug. 16, 1943. [Class 85] Means for obtaining cores in diamond or rotary drilling comprises a bit 1 with a tapered bore 11 adapted to co-operate with an outwardly tapered split ring 8 initially encircling the lower apertured end of a core tube 4 and slidably guided by lugs 5. At the upper end of the core tube is a non-return valve 45 allowing passage of water &c. and an adjustable threaded stem 6 which bears against a slidable valve member 7 pressed by a spring 30 and adapted to co-operate with a valve member 25. When short cores are required, a stop comprising a split tube 36 is locked at the desired height in the core tube by a screw 37 and a wedge member 38. Above the parts shown, a strainer is arranged in the drill tubing. In use, when the core sticks or contacts the stop or the end of the core tube, downward movement of the core tube stops. Drilling continues until the valve members 7, 25, contact to cut-off the supply of flushing water and so give an indication above ground; just before this, lugs 5 push the split ring 8 off the core tube, and on raising the drill string, the spring 30 acts through parts 7, 4, to press the split ring into the tapered bore 11 to cause the core to break.

Title: Method and apparatus for controlling the discharge of contaminants from ships
IPC: B63B13/00
Filed: 1976-02-13
Abstract: 1501332 Discharging contaminants from ships KEENE CORP 13 Feb 1976 [24 Feb 1975] 5753/76 Heading G3N A computer system monitors and controls the rate of discharge of contaminants, e.g. oil, from a ship to prevent the rate exceeding a predetermined value. Pump 14 transfers oily water 12 from bilge or ballast tank 10, via flow sensor 18, flow meter 20 and control valve 22, to the point of discharge from the ship. Centrifugal pump 26 samples the water and it passes it, emulsified, via optional filter 28 for solids, to detector 30 whose discharge goes into the sea or back to tank 10 via valve 34. If the oil content is too high for discharge, valve 22 is closed. The detector 30 measures the oil concentration in a known manner by projecting light through the liquid to a photo-cell while a second photo-cell receives light scattered within the sample by the oil, comparison of the two photo-cell outputs giving the concentration which is displayed on meter 36 with an audible alarm. It is also passed via wire 42 to computer 44 which can directly control the discharge from the ship or actuate a recorder 56 which keeps a record of the degree of contamination of the discharged water. A signal from meter 20 gives the liquid volume which passes to computer 44, via line 46, which combines volume and oil concentration to give total oil discharge which is charted. A signal on line 48 gives the vessel speed and the computer controls recorder 56 to give the quantity of oil discharged/unit distance of ship movement on a chart. A power control unit 52 puts the system in operation when flow sensor 18 is actuated. The computer has various controls for calibration, and controlling printout of voyage number, allowable oil discharge, total miles and total oil Fig. 3 (not shown). This printout can then be submitted to the authorities to confirm that the legal requirements have been met.

Title: Improvements in or relating to methods of life testing electric discharge devices
Inventor: BAKER BASIL OFFOR
IPC: H01J9/42
Filed: 1956-02-27
Abstract: 821,530. Cathode materials. GENERAL ELECTRIC CO. Ltd. Feb. 27, 1957 [Feb. 27, 1956], No. 6055/56. Class 39(1). In a method of life-testing discharge tubes having an emissive cathode coated with alkaline earth metal oxides, including barium, the tube is run for a specified time, and then the concentration of barium oxide remaining in the coating is measured ; from the fall in the concentration, the eventual life is estimated, since emission failure occurs at a known minimum concentration. In a specific example, the tubes tested were triodes, the cathode having a coating of mixed barium, strontium, and calcium oxides, in the molecular proportions 49 : 44 : 7. A specimen 5% of the total number were run for 1,000 hours under specified conditions. The cathodes were removed from the tubes in a nitrogen atmosphere, and coated with wax to prevent contamination. The remaining concentration of barium oxide was then measured by X-ray diffraction methods. It is necessary to establish a correlation between time and fall in concentration, which in the case of the above specific example was assumed from experimental results to be a linear relationship.

Filed: 1920-02-28
Abstract: 164,106. Mitchell, F. G. Feb. 28, 1920. Tipping-apparatus; lifting-cradles.-Wagons are tipped by raising them bodily on a cradle suspended by chains, and then tilting the cradle endways or sideways by manipulation of the winding- gear. The cradle is wheeled and adapted to be run under the wagon to be lifted while such wagon is stationary in contradistinction to a cradle on to which the wagon has to be run. Fig. 1 shows the construction adapted for end-tipping. A pair of cross-braced side bars a fitted with lugs for engaging and retaining one axle c' of a wagon, are run under the wagon on wheels a<1>. The hooked ends of the bars at each end of the cradle are connected by bridles f which in turn are connected by pairs of chains to other bridles m carrying a pair of pulleys. Winding ropes from independent drums driven by separate motors u are reeved round the pulleys of each bridle. The truck is raised to the required height by driving both winding drums at the same speed and is tipped by stopping or reversing one or other of the drums. For side-tipping, hooks v, Fig. 6, arranged on the sides of the bars a, are connected directly by chains to the bridles m. The axleengaging lugs in this case bear against the inner surface of the bosses of the adjacent wheels during the tipping-operation. The supporting-chains wrap round the side of the wagon on the tipping side of the cradle, as shown, and assist in preventing the wagon leaving the cradle. The wind. ing-drums may be mounted on a weighing-platform carried at the head of a wheeled crane or staith.
