Title: Improvements in ionization gauge circuits
IPC: G01L21/00
Filed: 1944-10-30
Abstract: 583,450. Resistance measurements; determining physical qualities of materials. DISTILLATION PRODUCTS, Inc. Oct. 30, 1944, No. 21194. Convention date, Nov. 13, 1943. [Class 37] Low gas pressures, of the order of 10<-4> mm. of mercury or less, are determined by measuring the positive ion current flow in the gas at the pressure to be determined. An ionization tube IT comprises an envelope 1 enclosing a cathode 2, anode 3, and positive ion collector plate 4. The envelope 1 is supplied with the gas whose pressure is to be measured by a tube 5. The cathode 2 is connected through a centre-tapped resistor 6 to a tap on the voltage dividing resistor 9 of a source of unidirectional potential. The anode 3 is connected to a doublepole two-way switch 16 which connects it in its upper position to a wire 17 and in its lower position across a tapping Z on the secondary winding 40 of a transformer T2 for degassing. The anode 3 is connected through a switch 18 and resistor 19 to a point on the resistor 9 which is positive with respect to the cathode 2. The positive ion collector plate 4 is connected through one of a set of resistors Rl, R2, R3, selected by a switch 23, and a portion of a variable resistor 25 determined by a movable contact 29 to a point on the resistor 9 which is negative with respect to the cathode. The voltage set up by the flow of positive ion current through the resistor R1 is opposed by a voltage of opposite polarity across the resistor 25, and the contact 29 is adjusted until these voltages are equal. The magnitude of the positive ion current and thus the gas pressure within the ionization tube can then be determined from the settings of the switch 23 and contact 29. A cathode ray tube CR1 indicates equality of the voltages in the ion. current circuit. In order that the positive ion current of the tube IT may accurately indicate the gas pressure, the electron current from the cathode 2 to anode 3 must be maintained at a predetermined value. This current is adjusted by varying the cathode heating current, adjustment to the desired value being indicated by a second cathode ray tube CR2. The cathode terminals Y are connected through a rheostat 45 and switch 43 to a switch arm 42 engaging a. series of taps 41 on the secondary winding 40, by which the heating current may be varied. The' grid-cathode circuit of the tube CR2 is connected across the resistance 19 in the ionization tube anode circuit, a variable grid biassing resistor 49 being included in the cathode lead. By throwing the switch 18 to its lower position the grid-cathode circuit of the tube CR2 is connected across a portion of the resistor 9' through a fixed resistor 52. A current limited by the resistor 52 to the magnitude desired in the anode circuit then flows in the resistor 19 and the grid bias resistor 49 is then adjusted until the shadow angle of the tube CR2 is a minimum.

SAVY, JEANJEAN, ET CIE, Avenue Dubonnet, Courbevoie, Seine, France, and BAKER PERKINS, Ltd., Willesden Works, Hythe Road, Willesden, London. July 27, 1931, No. 21371. Convention date, April 23. [Class 87 (ii).] Shaking-tables for vibrating moulds or containers charged with chocolate, shoe-polish or other liquid or semi-liquid moulding-mixture, are arranged so that the amplitude of the vibrations varies continuously in cycles between successive maximum and minimum amounts. In the illustrated form the moulds 19, carried on the endless chains 20, pass over the shaking- frames 3 comprising two longitudinal bearers which carry brackets 4 fixed rigidly thereto near each end. All four brackets are linked to a common shaft 7 and in addition carry eccentric straps 10 mounted on shafts 11, 12 driven from an external source. The shafts 11, 12 are intergeared by a pair of sprocket or other wheels of which one has one tooth more than the other. Thus, starting from a position in which the eccentrics on the shafts 11, 12 are exactly in phase, one pair of eccentrics gain continually on the other pair until they are again in phase by the gaining of a complete revolution. During each of these periods the table rocks slowly about an axis parallel to tho shaft 7 in addition to each end being oscillated vertically by each rotation of the eccentrics. As modifications, each of the shafts 11, 12 may be driven independently at the varying speed and they may be arranged to turn in opposite directions.

Patent GB-460586-A (GB)
Title: Manufacture of ascorbic acids
IPC: C07D307/62
Filed: 1935-07-30
Abstract: Ascorbic acids are manufactured by condensing a glyoxylic acid ester with an aldosugar in an alkaline medium, for instance, in aqueous or alcoholic solution.  The ascorbic acids so produced are stated to possess the general formula <FORM:0460586/IV/1> where X may stand for O or a low whole number.  The preferred agents used to produce the alkaline reaction are the alkali metal cyanides such as sodium cyanide.  It is advisable that the reaction should be conducted in the absence of air or other oxidizing gas.  Instead of the free aldo-sugars derivatives may be used which form these free sugars in an alkaline medium.  Examples of derivatives which may be so used are aldonic acid nitriles or acetylated aldonic acid nitriles, which are transformed into aldo sugars by the action of alkali with elimination of hydrocyanic acid and saponification of the acetyl groups.  The conversion of the derivatives into the aldo-sugar may be effected simultaneously with the glyoxylic acid ester condensation.  In this manner there may be formed d-ascorbic acid from tetracetyl-d-xylonic acid nitrile, with intermediate formation of d-threose.  In the same manner using the optical antipode, l-ascorbic acid (vitamin C) is formed.  Detailed examples are given of the formation of (1) d-glucohepto-ascorbic acid by heating on the water bath a methyl alcoholic solution of d-glucose, glyoxylic acid ethyl ester and sodium cyanide.  The product is isolated from the reaction solution by means of its lead salt; (2) d-ascorbic acid by heating a methyl alcoholic solution of tetracetyl-d-xylonic acid nitrile, glyoxylic acid ethyl ester and sodium methylate.  The product is isolated as in example (1).  A sample has been furnished under Sect. 2 (5) of l-ascorbic acid made by suspending l-xylonic acid nitrile in methanol, adding glyoxylic acid ethyl ester and treating the solution in a nitrogen atmosphere with sodium.  The reaction solution is boiled for 25 minutes, acidified with hydrochloric acid and the product isolated by means of its lead salt.

Title: Improvements in method of polishing metal surfaces
IPC: C25F3/22
Filed: 1946-07-19
Abstract: 629,603. Electropolishing metals. LITTLE, Inc., A. D. July 19, 1946, No. 21656. Convention date, Feb. 2, 1943. Drawings to Specification. [Class 41]  A metal surface composed of silver, copper, cadmium and alloys thereof, including alloys of these metals with nickel and/or zinc, is electropolished by subjecting as anode in an electrolytic bath containing in solution a soluble simple cyanide of alkaline reaction capable of forming complex cyanides with the metal to be polished, there being an amount of the free simple cyanide in excess of any complex cyanide equivalent to at least .01 mol per litre, employing a potential difference, above the polarizing potential, between the electrodes, which is below the point at which periodic flashing or permanent film formation occurs, and applying these conditions for a period of time to effect the dissolution of superficial protuberances from the surface and to leave the surface polished. The potential difference is preferably maintained substantially constant and the anode is freely spaced from the cathode and other solid surfaces sufficiently to prevent the effects thereof which are found to promote periodicity or flashing, and also to avoid turbulence, when the electrolyte is agitated, preferably in stream-line relationship to the metal surface, e.g. by moving the anode with continuous forward movement. The soluble cyanide may consist of alkali metal cyanide, e.g. sodium or potassium cyanide and conductivity of the electrolyte may be increased by the addition of an inert electrolyte such as potassium carbonate or sodium sulphate.

Title: Document retrieval system
IPC: B65H67/06
Filed: 1964-05-26
Abstract: 1,026,800. Random access stores. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 26, 1964 [June 5, 1963], No. 21798/64. Heading G4M. In a random-access store, film strips are stored in separate compartments in bins 10- 13, each bin may be positioned to align a selected compartment with a path leading to an output station 24, and bins 10-12 have at least one empty compartment which is aligned with the path when a film strip is selected from a bin to the left, so that the selected strip may pass therethrough. In the embodiment shown each bin has an array of 8 x 8 compartments and each film strip has a 4 x 32 array of documents recorded thereon. Strip and document selection may be initiated from a punched card reader producing a 15-bit address signal made up from bin address (2-bits), film address (6 bits) and document address (7 bits). Strip selection.-The bin address is decoded by gates and routes the film address bits to solenoid valves 48, 49, 50 or 51 which control piston adders to place the selected bin with the desired compartment aligned with the transport path. Bins to the right of the selected bin are automatically positioned with their empty compartments in alignment with the path. Strip ejection and transport.-The decoded bin address causes a pneumatic ejector 32, 34 or 36 to be positioned behind the selected bin 10, 11 or 12 in alignment with the selected compartment. Ejector 38 is fixed. Transport blocks 18, 20 or 22 remain in their normal position forming part of the transport path unless the ejector associated therewith is selected. The decoded bin address also opens the valve 106, 107, 108 or 109 to blow the selected strip out of its compartment. Air is also supplied to forward-angled jets in the blocks 16-22 to maintain the speed of the strip as it passes between the bins and station 24. Document selection.-Five bits of the document address are decoded to raise one of 32 stops 28 into the transport path, these stops corresponding to 32 columns of documents recorded on the strip. The remaining two bits are supplied to a piston adder 57 to position a lens over a selected one of four rows of recorded documents. Arrival of a selected strip at station 24 is detected by a photomultiplier and lamp 65 and this causes actuation of a shutter to record the selected document on film 64. Strip return.-After recording, air is supplied to backward facing jets in blocks 16-22 and the strip returns to its initial position. As the strip enters each bin, its presence is detected by photomultipliers 66p-69p the outputs of which are gated with the decoded bin address signal, so that it is only when the strip has returned to its original compartment that the output of the photomultiplier associated with the selected bin produces a signal which is used to start a new selection cycle. Fig. 4 (not shown) illustrates the application of the invention to a store which is similar to that described in Specification 1,003,509.
