Title: A method of processing a mixture of liquefied gases
Inventor: HARMENS ALEXANDER
IPC: F17C9/04
Filed: 1963-01-02
Abstract: Liquefied natural gas is separated into a gas containing methane and a minor proportion of ethane and a liquid containing propane, n-butane and a small amount of ethane by (a) partially vaporizing to obtain some gas; (b) subjecting the residual liquid to fractionation to obtain overhead gas and liquid bottoms; (c) partially condensing the gaseous overhead to obtain further gas and a liquid which (d) is recycled is reflux to the fractionation; (e) partially vaporizing the liquid bottoms to obtain liquid product and a gas which (f) is recycled to the fractionation.  In one embodiment the liquefied natural gas is partially vaporized by reducing the pressure and using the vaporization as a source of cold.  Alternatively, the pressure is increased before step (a) to the pressure required in step (b) and the liquefied natural gas is then used to cool the working medium of a closed compression/expansion system for converting heat into mechanical power.  The partial condensation in step (c) is achieved by indirect heat exchange with liquid from step (a) and gas from steps (a) and (c) or compressed gas from step (a).

Filed: 1953-01-05
Abstract: 725,145. Pencil sharpeners. TALL, M. Jan. 5, 1953, No. 294/53. Class 146(3). In a pencil sharpener of the kind comprising a pair of rotary cutters operated by planetary gearing and disposed with their axes at an acute angle to each other, there is provided between the cutters an adjustable stop for the point of the pencil, the stop being swingably mounted and tapering in thickness so that the clearance between the stop and cutters remains substantially constant as the stop moves along the central axis between the cutters. In the form of Figs. 2 and 7 the cutters 18 are mounted on a frame 13 secured to the main shaft 11 rotated by a handle n or by motor. The frame 13 comprises end blocks 14, 15 connected by bars 16, 17 and the cutters carry driving gears 19 engaged with an internally toothed ring gear in the stationary body of the sharpener. The stop 29 is pivoted to the bar 16 by a cross pin 30 and has an upstanding lug 28 engaged in an eccentric channel 27 formed in the underside of a manually rotatable disc 21 mounted on the bar 16 by a pin 23. Rotation of the disc causes the operative part of the stop to be displaced along the central axis of the cutters. The disc 21 is formed with a series of numbered radial recesses engaged by a retaining projection 26 on the underside of a resilient pointer 25. The stop is curved so that the part engaging the pencil point is always approximately normal to the axis of the pencil. The cutter assembly is surrounded by a container b for the shavings which must be taken off to effect an adjustment to the stop. In the form of Fig. 9 the stop 40 is similarly mounted and biassed in a clockwise direction by a leaf spring 45 bearing on a finger 41 integral with the stop. The position of the stop is determined by axial displacement of a push-rod 47 passing out through a bore in the driving shaft 48 and engaged, inside the hollow boss of the handle n, with an axially displaceable cam member 53. Wings 57, 58 on the member 53 prevent rotation and its helical cam surface 54 is engaged by a complementary surface 55 on the end of a manually rotatable knob 56 projecting from the handle boss. A washer 59 retaining the knob is formed on its inner face with teeth or serrations which engage similar teeth on the face of a flange 61 on the knob to locate the knob in the set position and to indicate the extent of rotational displacement. A pointer formed on the knob co-operates with index marks on the washer 59.
