Title: Improvements in or relating to the production of anesthetic compounds and intermediates therefor
Filed: 1944-09-27
Abstract: b -Octylaminoethyl p-nitro- and p-aminobenzoates are manufactured by condensing a b -octylaminoethanol with a nitrobenzoyl halide, preferably in an alkaline medium, and reducing the resulting nitrobenzoic ester.  The aminobenzoic esters and their salts may be used as anaesthetics, for surface application, e.g. in eye operations, or for injection.  In an example, b -(a 1-methylheptyl)-aminoethanol in aqueous sodium hydroxide solution is stirred with an ethered solution of p-nitrobenzoyl chloride and the resulting nitrobenzoic ester is reduced with iron filings and hydrochloric acid to b -(a 1-methylheptyl)-aminoethyl p-aminobenzoate, which is extracted with ether.  The free base may be isolated by evaporating the ether, or may be treated with water and hydrochloric acid to form the monohydrochloride, or with equivalent amounts of sulphuric, formic or other acids.  Tin and hydrochloric acid are also specified as reducing agent. Specification 482,886 is referred to.  b -(a 1-Methylheptyl)-aminoethanol is obtainable by refluxing monoethanolamine with 2-bromoctane, adding aqueous sodium hydroxide solution and extracting with ether.  A sample has been furnished under Sect. 2 (5) of b -(b 1-ethylhexyl)-aminoethyl p-aminobenzoate sulphate, made as in the example above from b -(b 1-ethylhexyl)-aminoethanol (prepared from monoethanolamine and b -ethylhexyl bromide).  The Specification as open to inspection under Sect. 91 comprises also the manufacture of the corresponding o- and m-nitro- and aminobenzoic esters, e.g. by replacing the p-nitrobenzoyl chloride in the example above by o- or m-nitrobenzoyl chloride. This subject-matter does not appear in the Specification as accepted.ALSO:b -Octylaminoethyl p-aminobenzoates and their salts may be used as anaesthetics, for surface application, e.g. in eye operations, or for injection.

Title: Improvements in or relating to the purification of gases
Inventor: BANKS REGINALD JOSEPH HENRY
IPC: C10K1/12
Filed: 1956-06-15
Abstract: 869,131. Purifying gas. GAS COUNCIL. June 14, 1957 [June 15, 1956; Oct. 29, 1956], Nos. 18657/56 and 32938/56. Class 55 (2). In a process for removing hydrogen sulphide from a gas, the gas is washed with a reagent comprising initially a suspension or solution of zinc hydroxide and/or basic zinc carbonate in an alkaline aqueous solution containing the hydroxide, carbonate or bicarbonate of an alkali metal or any mixture of such compounds. The alkali content of the reagent is preferably equivalent to at least 1.0% by weight sodium carbonate and the zinc content not less than 0.02% by weight. The reagent may be prepared from alkali metal zincates or from soluble zinc salts, e.g. zinc sulphate or acetate, and an alkali metal hydroxide, carbonate or bicarbonate. If hydrogen cyanide is also present in the gas to be treated an alkali cyanide may be added to the reagent. In an example a reagent containing 0.075% by weight of zinc and 2.0% by weight of sodium carbonate was employed with a gas/reagent contact time of 11 seconds. Precipitated zinc compounds may be kept in suspension in the reagent by continuously passing the reagent through a centrifugal pump. The reagent may be regenerated by filtering off precipitated zinc sulphide, roasting the zinc sulphide to zinc sulphate and preparing fresh reagent from the zinc sulphate.

Patent GB-482884-A (GB)
Title: Improved process and apparatus for producing high vacuum
IPC: H01J9/385
Filed: 1936-07-06
Abstract: 482,884. Obtaining high vacua. KODAK, Ltd. (Eastman Kodak Co.) July 6, 1936, No. 18762. [Class 8 (i)] A high vacuum is obtained in a vessel by alternately and repeatedly putting into and out of communication with it an absorption surface such as the bristles 6, Fig. 1 ; the gases absorbed during communication are discharged by an electrode 7 or by heating or electronic bombardment in the non-communicating position, and withdrawn by a backing pump. The bristles are mounted on a rotary drum to effect the alternate communication of each part of the absorption surface with the vessel and the backing pump. A rotary disc or a band travelling over pulleys may replace the bristled drum, its surface being, e.g. of tungsten or molybdenum or coated, e.g. with activated charcoal, silica or silicates, aluminia, various metals, cellulose or its derivatives, or resins. Fig. 9 shows apparatus in which absorption takes place on a part of the inner surface of the conduit 2, 3, this part being separated by a plate 106 rotated by a magnet 120 from another part in which a rotary heating plate 116 drives the absorbed gases off to the backing pump. With a mercury-vapour backing pump, a goldabsorption surface may be employed.
Patent GB-498399-A (GB)
Title: Improvements in or relating to automatic switches as used in telephone or like systems
IPC: H01H63/20
Filed: 1937-07-06
Abstract: 498,399. Automatic exchange switches ; oscillating motors. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and GRAHAM, J. ST. C. W. July 6, 1937, No. 18814. [Class 40 (iv)] [Also in Group XXXV] In a step-by-step ratchet-driven switch fed with alternating current, the driving magnet has a copper slug 17 of such dimensions that the rate of stepping under the control of interrupter contacts 14 is directly related to the frequency of supply. For example, if the magnet armature is pulled up at the point A, Fig. 3, in the first half-cycle, the slug may cause it to be held until the point B, the interrupter contacts being reclosed at C and the armature being again pulled up at D. With this relationship the rate of stepping is equal to the frequency of the supply, but by increasing the size of the slug and, if necessary, the moment of inertia of the armature (by a weight 19) and the wiper load, the switch may be arranged to step once for each three halfcycles, once for each four half-cycles, &c. The switch may have two separate sets of interrupter contacts 14, 15 operated by a pair of extended arms 12, 13 on the armature and may be arranged to be controlled either directly by interrupter contacts or by a relay controlled by interrupter contacts. In the latter case and when controlled directly by alternating current without using interrupter contacts (e.g. when responding to A.C. impulses), the speed of stepping is independent of the frequency of the supply, the slug holding the armature as long as the supply circuit is closed. The magnetic circuit comprises U -shaped laminations adjustably held by screws 23 engaging slotted holes in the frame 25, with locking screws 26 to prevent displacement due to hammering of the armature. The polepiece 16 has an inclined face as shown and is slotted, the slug 17 being mounted on one half. An eccentrically-pivoted roller 28 serves as an adjustable back-stop for the armature.

Title: An improved method of detecting or indicating faults in pressure circuits of electrical apparatus, more especially in the pressure circuits of alternating current meters
IPC: G01R35/04
Filed: 1931-06-30
Abstract: 363,967. Supply meters ; pressure meters ; indicating faults; combinations of instruments. LANDIS ET GYR, SOC. ANON., 1, Hofstrasse, Zug, Switzerland. June 30, 1931, No. 18843. Convention date, July 24, 1930. [Class 37.] In order to indicate faults in pressure circuits of electrical ap. paratus, especially alternating current meters, alterations of pressure are arranged to cause alterations in the position of one or more thermaldevices. Around each pressure coil 2, 2<1> of a polyphase meter is arranged a winding 3, 31 connected to a bifilar wound bimetallic spiral 8, 8<1>. The inner ends of these spirals carry pointers 12, 12<1> which move over scales 9, 10 on the counting-train dial plate 11. Under normal conditions the current induced in the coils 3, 3<1> is sufficient to keep the pointers at about the graduation 2 on the scales 9, 10. Melting of the central fuse causes the pressure coils 2, 21 to be connected in series and receive only half their normal pressure, the pointers consequently moving back to the graduation 1. On breakage of the wire in one pressure coil, the corresponding pointer reading falls to zero. On excess pressure occurring, one or both pointers move towards the graduation 3. Instead of the bifilar-wound bimetallic springs, two bimetallic springs lying side by side may be employed, the inner ends being connected to a pointer. The pointer may be replaced by indicating discs which appear behind apertures in the casing on the occurrence of a fault. In alternative arrangements the windings surrounding the pressure coils may each be connected in parallel with one another through a bimetallic device, or they may be connected in series with one another and with a bimetallic combination.

Title: Process and installation for eliminating sulphuretted hydrogen from gases
IPC: C10K1/12
Filed: 1926-08-04
Abstract: 271,805. Still, C. May 25, 1926, [Convention date]. Materials for purifying gas.-In removing sulphuretted hydrogen from gas by washing with an aqueous suspension containing ferrous and ferric hydroxides or carbonates, which is regenerated by treating with air, the circulating suspension never contains more than 2 per cent of iron. The wash liquor may be rendered alkaline by means of ammonia solution or a solution of sodium hydrate or carbonate, or by means of the ammonia present in the gas being treated. The sulphided liquor flows from the scrubber 2 to a tank 6 and is pumped into the bottom of a regenerating tower 10 provided with an air supply pipe 11. A foaming mass containing regenerated ferric hydroxide or carbonate together with sulphur passes off from the top of the tower through a pipe 12 to a receptacle 13 in which the sulphur is to a large extent separated as a foam from the suspension which is returned to the spray 4. The foam which consists of sulphur with a small amount of iron floats off to a receptacle 16 and after draining, passes to a centrifuge. 19. The small amount of iron withdrawn from the system with the sulphur is replaced by adding a ferrous or ferric salt solution which is made up in a vessel 25 and passed to the tank 6. When neutral washing liquor is used, alkali is added to precipitate the iron as hydrate or carbonate. With repeated circulation a concentrated solution of thiosulphate is formed and when this is withdrawn from the plant, a correspondinging amount of alkali must be introduced unless the gas being purified contains ammonia.
