Title: Improvements in fractional distillation
IPC: B01D3/14
Filed: 1936-05-04
Abstract: In a fractionating-still for hydrocarbon oils or other composite liquids, the quantity of each side-stream withdrawn is automatically maintained a definite percentage of either the overhead or the bottoms fraction or, as shown, of the charge supplied, irrespective of the quantity or temperature of the charge or quantity of steam used.  Oil supplied at 14 passes through a furnace 11 and enters at 15 a column 16 having a perforated steam coil 18 and bubble-trays 17 with pockets 24 where the side-streams are taken off at 21, 22, 23, the vapour and bottoms being respectively withdrawn at 19 and 25. The temperature of the vapour is maintained constant by a power-actuated valve 30 in the reflux line 20 controlled by a regulator 27 influenced by a temperature-responsive element 26. The charge is kept constant by a valve 32 controlled by a flow-regulator 31 in response to pressure-differences at an orifice - plate 33.  The side-streams are proportioned to the flow in the line 14 by valves 47, 50, 53 controlled by differential regulators 40, 48, 51, each subject to the pressure-differences at the plate 33 and at one of the orifice - plates 43, 49, 52 in the lines 21, 22, 23.  Internal or external stripping-sections may be provided.  The temperature of the vapour and sizes of the orifice-plates are chosen to correspond with the laboratory evaluation of the crude oil, a numerical example being given.  The regulators may be mechanical, electric, hydraulic, or pneumatic, those shown being of the "Foxboro Stabilog" type, wherein pressure-difference in the lines 35, 36 deflects mercury in a pressure chamber 34, which operates a float to move a vane towards and from a nozzle controlling the flow of compressed air from a supply 38 to a valve-motor line 37.  In the differential <PICT:0461405/III/1> regulators, the movement of parts in, say, the chamber 41 sets the mechanism in chamber 42 to admit such pressure to valve-motor line 46 as will maintain the proportionality determined by the chosen orifice-plates.

Title: Improvements in or relating to semiconductor signal translating devices
Inventor: GIBSON ALAN FRANK
IPC: H01L29/00
Filed: 1955-05-03
Abstract: 812,550. Transistors. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 23, 1956 [May 3, 1955], No. 12771/55. Class 37. A transistor comprises a body of semi-conductor consisting of a first zone of one conductivity type at least one surface of which is a surface of the body, a second zone of the same conductivity type but of greater conductivity located within the area of the surface and making a small junction therewith, ohmic connections to each of the two zones and a rectifying connection to the first zone. The device shown in Fig. 2a is made as follows. An N-type Ge body 1 is heated in contact with an Sn Sb alloy coating on a nickel plate 2 to form an N + zone 8 therein adjacent the connection. A series of Sn Sb blobs 3 are alloyed to the other surface of the G body to give further small N + collector zones and a series of In blobs 4 then alloyed to the body adjacent the Sn Sb blobs to provide small P-type emitter zones. The resulting assembly is then divided into bodies each comprising a pair of the dots. Connecting wires 6, 7 are soldered to the dots and the device then etched in hot hydrogen peroxide. A heating step may be avoided if a sheet of the alloy is used instead of a coating melted on the Ni plate by fusing the dots 3 and the sheet to the body in a single operation. The connecting wires may be made of the same material as the dots or may contain such material in which case the dots may be dispensed with and the wires fused to the Ge directly. In a further embodiment the alloy dots 3 and 4 are fused to opposite faces of a Ge wafer and a base connection made through an N + region to the edge of the wafer. In another arrangement, in which the alloy junctions are again on opposite sides of a wafer the base connection is in the form of an apertured plate closely surrounding the collector junction. The Provisional Specification describes a modification of this form of transistor in which the emitter junction is replaced by a photo-sensitive surface. Transistors of the above type have greater current gains than junction transistors of the NPN and PNP types and admit of heavier loading than point contact transistors. Specification 700,231 is referred to.

Filed: 1945-05-22
Abstract: 592,566. Measuring short time intervals. STANDARD TELEPHONES & CABLES, Ltd., and EARP, C. W. May 22, 1945, No. 12813. [Class 37] The time interval between the starting instants of two trains of waves of the same frequency is measured by applying each train to a series of frequency dividers D1 . . . D4 and D<1>1 ... D 14 and measuring the phase difference between the outputs of corresponding dividers. Preferably, the frequency dividers divide by 10. As applied to measurement of the velocity of a projectile, pulses produced by the projectile in passing predetermined points are applied respectively to switches S1, S2; the time interval is thus related to a train of impulses of known frequency ; phase measuring device P1 indicates the units digit of the number of cycles in the train, phase meter P2 indicates the tens digit, meters P3 and P4 indicating hundreds and thousands digits. The switches S1, S2 are preferably thermionic switches. The invention may also be applied to measuring the time of operation of a relay, and to measuring transit times through delay networks, telephone lines, &c. The phase-measuring device preferably consists of a cathode-ray tube in which the beam traces a circular path under the control of one of the frequencies which is split into two oscillations 90 degrees out of phase ; the other frequency is applied to a circuit to produce a peak impulse for each cycle which modulates the intensity of the beam so that the relative phase of the two frequencies is represented by the position of the spot on the circular trace.

Abstract: 344,279. Treating artificial silk. GLANZSTOFF-COURTAULDS GES., 2, Neusser Landstrasse, Merheim, Cologne, Germany. April 29, 1930, No. 13194. Convention date, April 29, 1929. [Class 2 (ii).] Spun cakes of artificial silk are washed, desulphurized, bleached, or dyed by mounting on solid supports and introducing the treatment liquid into the interior of the cake so that it flows over the top edges of the cakes. This liquid current serves to loosen the thread layers and so enable the treatment liquid to pass between the layers without the use of undue pressure. The extent of loosening of the threads is limited by allowing the cakes to gain in height by a predetermined amount. A number of cakes may be treated in one operation (Fig. 1) by placing them on supports A arranged upon a perforated tube B in such a manner that the top of one cake is several millimetres or one or more centimetres from the support of the next cake above it. When treating cakes singly, they are placed upon a support A (Fig. 2) and covered by a hood C, the top of which is at a sufficient distance from the top of the cake as to allow of the necessary expansion.
