Filed: 1974-06-28
Abstract: 1436287 Electro-chemical determination of gases FRANCE ARMED FORCES MINISTER OF 28 June 1974 [7 Aug 1973] 28913/74 Heading G1N A method for detecting the presence in a gaseous medium of a gas which dissolves in water to form an anion, or for detecting the presence of a particular anion in aqueous solution, comprises mixing the gaseous medium or the solution with an electrolyte, supplying the mixture to an electrochemical cell having an electrode made of a metal which forms a complex with the anion to be detected, and measuring variations in the electrolyte current, while the voltage applied to the cell alternates on either side of the complexing potential between the metal and the anion and on either side of the thermodynamic neutrality potential of the cell. The height of the peak of the current curve, or the integral of the peak as a junction of time or voltage, gives a measure of the concentration of the anion. Using the cell shown in Fig. 2, a mixture of gas to be tested and electrolyte is admitted through Venturi tube 5 into condensation chamber 45 as fine droplets which pass into measuring chamber 49. The working electrode 3, reference electrode 9, and a counter-electrode 4 are connected through an impedence matching device to an electronic system for monitoring variations of the electrolytic current. The working electrode may be made of Al, Zr, or Hf for detecting fluoride, or of An, Ag, or Pt for detecting cyanide. Potassium iodide or bromide may be added to the electrolyte to produce current peaks which are removed or reduced by the presence of ions to be detected. For detecting an anion in a liquid a modified cell, Fig. 8 (not shown), is used.  The electronic system, Fig. 3 (not shown), comprises a potentiostatic device for maintaining the potential of the reference electrode at a desired value, a sample and hold device to which a signal representing the strength of the electrolytic current is applied, an integrator, and a staircase generator. In examples, cyanide is detected in air using a gold or silver working electrode and an electrolyte comprising KOH, K 2 SO 4 , and KI. A borate may be added to the electrolyte to suppress drift of the thermodynamic neutrality potential.

Title: Improved process of purifying lactic acid
IPC: C07C51/48
Filed: 1921-11-01
Abstract: The lactic acid or lactate to be purified is first converted into magnesium lactate by heating its solution with magnesium compounds such as carbonate, hydroxide, or oxide. One method of carrying out the process is by double decomposition of the more easily soluble lime compound or other soluble lactate with a suitable magnesium compound such as sulphate. The acid is then liberated either by direct acidification with sulphuric acid and extraction with acetone, ether, etc.; or the magnesium lactate is suspended in acetone or ether and then agitated with sulphuric acid when magnesium sulphate separates and the solution of lactic acid is evaporated. The product in each case may be purified with boneblack. In examples, commercial lactic acid is treated with magnesia and the resulting lactate treated by each of the above-described methods. The Specification as open to inspection under Sect. 91 (3) (a) describes also the preparation of the magnesium lactate by effecting the lactic acid fermentation in presence of basic magnesium compounds.  This subject-matter does not appear in the Specification as accepted.

Title: A Bidirectional Step by Step Feeding Device for a Record Support, for example a Punched Tape
IPC: H04L13/06
Filed: 1967-06-26
Abstract: 1,191,350. Feeding records. ING. C. OLIVETTI & C. S.p.A. 26 June, 1967 [27 June, 1966], No. 29313/67. Heading G5R. [Also in Division F2] A record 17, e.g. a punched tape or card, is incrementally driven through a differential gear including sun-wheels 71, 73 controlled through respective clutches operable together to advance the record, and only one operable to backspace the record. A punched tape teleprinter is described in which the tape 17 is fed through a punch 16 by a drive roller 81 driven by shaft 74 to which the planet wheel pivot 79 is secured. A gear 39 is constantly driven to rotate a sleeve 34 in turn driving a sleeve 54 via pinions 61, 59, the sleeves 34, 54 carrying pinions 38, 57 allowed to rotate without meshing with gears 31, 48 by cutouts 32 and 49, 51 respectively. Upon receipt of a message, a main control shaft (113, Fig. 2, not shown) is rotated once, the punch combination set up and cams (112) operated to press a lever 101 against links 93, 99 controlling the clutches. The sleeves 34, 54 are therefore axially shifted so that start lugs 37, 58 engage lugs 33 and 52, 53 on further sleeves 27, 47 to allow pinions 38, 57 to mesh with gears 31, 48 thereby rotating pinions 69, 72 on the further sleeves 27, 47 to drive the sun-wheels 71, 73 in opposite senses so that the planet 78 rotates on its pivot 79. The roller 81 therefore remains stationary while cams 26 operate a bail 23 to punch the tape. A pin 62 on sleeve 54 engages a face cam 63 to shift the sleeve 54 and thereby links 93, 91 to shift sleeve 34. One of two stop lugs 66 on sleeve 47 engages a cylinder 67 on sleeve 54 to stop rotation of sun-wheel 73 after a total of 180 degrees of sleeve 47 rotation, while sleeve 27 continues for a further 180 degrees, thereby driving sun-wheel 71 to advance the tape by one increment, until a stop lug 42 engages a cylinder 43 on sleeve 34. Backspacing is effected by manually operating a linkage (Fig. 3, not shown) preventing more than one backspace increment, to press a member 144 against clutch control lever 93 only, thereby rotating sun-wheel 73 to backspace the tape.

[Also in Divisions D1 and H2] For generating an electrical impulse at a predetermined angular position of a rotary shaft 1, a synchronizing device comprises a member 6 stationary when in use and carrying a Hall generator 7 adjacent which may pass two mutually oppositely poled permanent magnets 4, 5 carried in different angular positions by a rotary member (10), Fig. 3 (not shown), attached or attachable to the shift 1, the oppositely poled potential pulses responsive to such passage being applied by the Hall generator to a control circuit which includes means, e.g. a differential amplifier 28, 29 to transmit and block pulses of respective polarities, and control means, e.g. a bi-stable multivibrator 37 to reverse the polarity of the supply voltage applied to the Hall generator 7. The device is usable with an electric motor comprising an electromagnetically operable friction clutch and brake and driving, e.g. a spring coiling machine or a sewing machine, and is operable to stop the shaft at one of a plurality of optionally selectable angular positions as defined by adjustment of semicircular discs 2, 3 mounting the magnets. To provide additional stopping positions, there may be another Hall generator and pair of magnets.
Patent GB-464644-A (GB)
Title: Improvements in suspensions for lubrication and other purposes
Filed: 1935-10-25
Abstract: A liquid mineral oil or equivalent hydrocarbon is rendered capable of suspending finely divided particles, without destroying the free flowing character of the medium, by gelling the oil with "hydrogenated castor oil wax" and agitating to produce a discontinuous, gelatinous body.  "Hydrogenated castor oil wax" is the wax-like product obtained by treatment of castor oil with hydrogen in the presence of a nickel or cobalt catalyst.  Thus, a small amount of the wax is melted and dissolved in the oil by heating to 200--250 DEG F., after which the solution is cooled to form a gel and the gel is then broken up, by agitation, to form a suspending medium for lubricant in particles.  Examples are given of the preparation of cutting, &c. lubricants containing sulphur particles.  To avoid agglomeration of the particles a small amount of sulphonated castor oil may be added.  A lubricant base may be prepared in concentrated form, capable of dilution with petroleum oil for use.  Other finely divided solid lubricant particles which may be stably suspended comprise finely-divided selenium, tellurium, talc, slaked lime, white lead, white zinc, and cork dust.  Suspensions for grinding, lapping and polishing mixtures may also be made containing suspended particles of emery, corundum, rouge, whiting, &c.  U.S.A. Specification 1,913,300 is referred to.
