Filed: 1938-08-26
Abstract: 521,942. Thermionic valve circuits. THORNTON, A. A. (Philco Radio & Television Corporation). Aug. 26, 1938, No. 25122. [Class 40 (v)] The cathode or filament of a valve is rendered electron emitting in reduced time by initially applying an excess voltage or by the discharge of a condenser. Fig. 1 shows an arrangement in which the high tension voltage B is momentarily applied while switch arm S engages contact 1 before the application of the normal voltage A. The filament may be entirely energized from the high voltage source by repeated short applications of high voltage, Fig. 2 (not shown). Fig. 4 shows an arrangement in which heating is effected by the successive discharging of condenser C which is charged through a resistance R. In a modification, Fig. 3 (not shown), closure of the switch discharges the condenser and heating is maintained by the battery and resistance in series. Alternatively the initial heating may be by condenser discharge and the heating be maintained from a low voltage source, Fig. 5 (not shown).

Abstract: 706,805. Making capsules. AMERICAN CYANAMID CO. Nov. 1, 1951 [Nov. 3, 1950], No. 25563/51. Class 87 (2) In making capsules by a method that includes the step of sucking a gelatin &c. sheet into the cavities of a die roll, the waste part of the sheet, i.e. that part of,the sheet that is not sucked into the cavities, also is sucked on to the surface of the die roll to keep it still. Figs. 1 and 2 show a die roll 11 having staggered cavity-forming inserts 12 fitted into slots 13. Through the bottom of each insert extend two capsuleejecting pistons 18 disposed in cylinders 16 connected by manifold 19 to vacuum chest 22. The vacuum is applied to the underside of the gelatin sheet 15 through the gaps between the pistons and the contiguous die roll parts, and sucks the sheet into the cavity, as shown. At the same time the parts 15<1> of the gelatin sheet that lie outside the cavities are sucked onto the surface of the die roll by vacuum through passages 24 formed in the walls of the slots 13. The cavities may be circular in shape. The vacuum may be appliedto only certain parts, of the waste (Fig. 3, not shown). In a modification (not illustrated) independent passages may extend from the manifold 19 to the surface of the die roll beneath parts 15' of the sheet. In a further modification, Fig. 5, the two suction supplies, are separate from each other viz., one to the cavities via manifold 19 and one to the parts 15<1> by passages 26. The vacuum line 23 that serves the cavities is separate from the vacuum line 28 that serves the waste parts 15<1>, and the waste may be sucked on to the roll before, whilst or after the sheet is sucked into the cavities.

Abstract: 1304995 Wells &c BYRON JACKSON INC 19 April 1971 [20 April 1970] 25886/71 Heading E1F Apparatus for cementing casing C2 in a subaqueous wellbore W2, includes a mandrel M supporting cementing plugs TP, BP by shear pins 35. The mandrel has an annular piston 74 which when the bore of the plug TP is closed is slidable downwardly in a chamber 72 under the effect of mud pressure to press against the plug TP and assist the pressure on the plug in shearing the pins 35. The mandrel, plugs and casing are run into the well on a tool T, the plugs being connected by shear pins 43. A ball 51 is released from a slide 56 to land on a seat 48 in the plug BP, the pins 43 shearing as cement is pumped down the well onto the ball. The descent of the plug BP stops when it reaches the casing shoe S the upper part of the casing then being "on vacuum". Pressure is equalized between the inside and the outside of the mandrel above the plug TP after the passage of the cement, by ports 76, 77. A dart 52 is released from a member 58 and travelling in advance of mud lands in a seat 52a in the plug TP, wiper rings 63 on the dart closing the ports 76, 77. The pressure shockwave produced in the mud when the dart 52 lands is dissipated by mud from the mandrel entering a surge chamber 83 through inlets 81 behind the dart. This prevents the shock wave shearing the pins 35 and ensures a pressure build up followed by a pressure drop measurable at the surface when the plug TP is released by shearing the pins 35 on increasing the mud pressure. The descent of the plug TP behind the cement causes the ball 51 to pass through the bore in the plug BP and seat on a catcher 49a, so that the slurry is forced through apertures 49b in the plug BP and through the shoe into the casing-wellbore annulus, until the plug TP lands on top of the plug BP. The plug BP may be omitted when cementing larger diameter (20 to 30 inch) casings.
