Title: Tank gauging device
IPC: G01F23/16
Filed: 1961-04-07
Abstract: 948,977. Indicating liquid levels. F. C. MELCHIOR. April 7,1961 [April 25, 1960], No. 12659/61. Heading G1H. In the determination of the height of the column of liquid in a tank 10, for example volatile liquid such as petrol, wherein the space above the liquid is pressurized, the difference in pressure between the top and the bottom of the liquid column is measured by a differential pressure measuring instrument 16, for example of the type described in Specification 774, 844, which communicates via a line 18 with an intake tube 22 ending a short distance from the bottom of the tank, at such a point as to be clear of sediment, and via a line 20 with a tube 48 which passes through an arm 34 hingedly connected by braces 38, 40 to the inside of the tank and which terminates at a float 32, said float being hingedly connected to the arm 34 by a bridging connection 36. The float 32 maintains the same position at the surface for any level of liquid, and the end of the tube 48 is positioned to measure the pressure at a fixed distance from this surface. Between the tube 22 and the differential pressure measuring instrument 16 is provided an isolator 34 having two chambers 26 and 28 separated by a thin, non- springing, flexible diaphragm 30, the instrument 16 thus being isolated from the liquid in the tank. A pressure bottle 54 containing pressurized gas such as carbon dioxide or nitrogen is connected to the line 20 so that on operation of a control valve 56 in the neck of the bottle a trickle of gas flows into the arm 34 to purge the line of liquid vapour which is thereby prevented from reaching the instrument 16.

Title: Improvements in and relating to variable electrical condensers
IPC: H01G5/38
Filed: 1925-05-15
Abstract: 246,362. Newey, J. G., and Jerred, C. B. May 15, 1925. Condensers of the variable type have the parallel spaced plates of substantially square or rectangular line and arranged in sets or blocks, each of which is rotatable about an axis at rightangles to the surfaces of the plates. The moulded insulating disc a carries a sleeve d in which is the spindle carrying a pinion f for moving the plates k, which are carried by sleeves g mounted on spindles h having their upper ends moulded. into bosses j on the disc a. The plates have attachment lugs k<1> forming a continuation of one diagonal and, to avoid electrical losses, the lugs are soldered in slots in the sleeve g. During the assembly the plates are held in a jig and lugs on the plates are soldered into slots in a metal ba,r l to keep the plates in position. The sleeves g are rotated by toothed insulating segments m provided with blanks m<1> to limit the travel, while the gearing is preferably such that a complete revolution of the knob effects the full range of tuning. The spindle carries a tag r connected with the sleeve by flex r<1>, and to effect a temporary connection terminals s may be provided. Owing to the spacing of the plates well away from the knob, hand capacity effects are avoided, and it will be seen from Fig. 3 that in any position of the knob the overlapping area is a rectangle, or a square in the " all-in " position, thus giving definite and equal change in the capacity throughout the whole range. Fig. 4 shows the " all-out " position, and it can be seen therefrom. that there is a low minimum value.

Abstract: 414,477. Safety razors. GILLETTE SAFETY RAZOR CO., 15, West 1st Street, Boston, U.S.A. May 1, 1933, No. 12670. Convention date, May 27, 1932. [Class 30.] The clamping - plate 34 and guard-plate 10 are interconnected by a slide action, which permits bodily longitudinal rectilinear movement of the clamping-plate to uncover the blade 46 and also permits the plates to approach or recede from each other to flex the blade over fulcrum shoulders 14 of the guard. One end of the clamping-plate 34 is connected by a neck 36 with a flanged slide 38, underlying the guard and engaging a grooved guide 22 movable in a forked part 18 between the integral guard and handle 20, the guide being riveted to an internal handle plunger moved axially by an end nut 32. One end of the guide 22 is turned over to form a lip 28 adapted to overlie a lip 40 of the clamping-plate, so that by turning the end nut 32, the clamping-plate 34 is drawn down evenly from both its ends to flex the blade. The slide 38 at one end carries a transverse pin 37, which abuts against stop-pins 25 in the guide 22 to limit outward travel and also forms a hinge-pin to allow the clamping- plate to fall away into the position shown in Fig. 6. During blade-flexing, the slide 38 is locked against all but perpendicular movement by engagement of a pin 44 with a hole 42 in the slide. The sliding and tilting movement of the clamping plate may be effected by gravity after the simultaneous release of the bladetension and the locking-pin 44. The slotted blade is located by diamond-shaped pegs 16.

The packer is lowered into position in the well casing B on a running string connected to a member-50 of asetting tool C, the member having extensions 52 109 and the extension 109 engaging the valve. At the required position of the packer the string, the member and extensions are rotated to the right, a slip setting and retaining structure 61 being held against rotation by a drag member 66 so that a nut 72 is freed from the member 50 which with the extensions and the packer is then moved downwardly by the string until the slips 28 are freed from a sleeve 60 and expanded by springs 45. The string is lifted to cause the expander 24 to set the slips 28, and to shear a screw 25 to permit the body to move upwardly to expand the packing against the casing, the body 'being held in the packing compressing position by a ratchet lock ring 33. Further lifting of the string shears the screws 17, and sets the slips 12 and the packer. After a screw 53a has been sheared by upward pull on the string the extensions may be moved upwardly until a stop 52b engages a nut 53 when the string may be rotated to the right to unthread the nut 53 from the body so that the string member 50 the extensions and the structure C may be removed from the well. The extension 109 may be run into the packer on another tubular string. When the packer is run into and set in the casing the valve is held by the latches 100 so that the space below the packer is in communication with the interior of the string through the ports 90, the extensions, and the member 50. After the packer has been set and the screw 53a has been sheared upward pull on the string closes the ports. When the string is raised to remove the extension 109 the ports are closed, the valve being retained in position by the engagement of the latches with a groove 103.
