Title: Improvements in wireless transmitters
IPC: H04L27/04
Filed: 1920-01-31
Abstract: 162,761. Ditcham, W. T. Jan. 31, 1920. Thermionic oscillation generators; keying systems and apparatus. - In a valve transmitter, " key clicks" may be obviated and the valve or valves relieved of the full load during the spacing periods of the morse characters by connecting in the primary power circuit a choke coil, if the primary current is alternating, or a resistance, if the current is direct, with a key or switch by which the choke coil or resistance may be shortcircuited for the purpose of signalling. The coil or resistance is of such a value that, when the key is open, the valve, although continuing to oscillate, only generates a small fraction of its normal working current. An iron-cored choke coil C in the circuit of an alternator A is arranged to be short-circuited by a key K. A rectifying- valve R and an oscillating valve V are provided.

Title: Improvements in means for measuring respired air in testing the lungs and for analogous purposes
IPC: A61B5/08
Filed: 1923-02-02
Abstract: 215,092. Brown, H. Feb. 2, 1923. Spirometers. - A device for measuring the capacity of the lungs and tidal breathing comprises a liquid receptacle into which respired air is breathed, the liquid being in part expelled into an observable tube when its level measures the pressure and in part through a restricted orifice into a measuring vessel. The receptacle 1 containing water or other liquid has an inlet 4<a> with flexible pipe 3, a tube 5 with transparent upper part and a construction 5b, the lower part dipping into the liquid, and a second tube 6 rising into the tube 5 to above the surface of the liquid and also having a small hole 9 communicating with the exterior of the receptacle 1. Air respired into the apparatus through the opening 4<a> expels liquid both up into the tube 5, where its level and consequently the pressure may be observed, and out through the hole 9 into a measuring vessel 11. If desired, some of the respired air may be allowed to escape without displacing liquid by means of a slot 7 and revolving shutter 8 on the tube 4 or other similar device in the cover 2. The shutter 8 may carry an indicator 20 moving over a scale 21, so as to measure the extent of the opening. Further, the amount of air passing through the tube 4 may be restricted by means of a perforated plug inserted therein. The apparatus may be employed to measure tidal breathing by the provision of a flexible diaphragm 13 in a closed receptacle 12 above the cover 2, there being a wide aperture 15 through which air is respired by means of a flexible tube 18 and a small aperture 16 communicating with the interior of the receptacle 1. A small hole 14 is also provided, this being normally closed by a shutter 14<a>, which during tidal-breathing tests serves to close the hole 9. Further, the tube 5 is removed and a plug substituted therefor.

Title: Improvements in or relating to electric switches and magnetic operating means therefor
IPC: H01H50/30
Filed: 1955-02-03
Abstract: 784,163. Magnetic switches. FLIGHT REFUELLING, Ltd., and JONES, E. C. Jan. 25, 1956 [Feb. 3, 1955], No. 3231/55. Class 38 (5). A switch comprises a horseshoe magnet 35 mounted on a shaft 34 rotatable by a float 39 responsive to the liquid level in a tank 13. The magnet operates an armature 31 situated on the other side of a non-magnetic fluid-tight partition 15 and mounted on a spindle 26 coaxial with the shaft 34. The limit positions of the armature are to either side of a mean vertical position and are determined by the walls of a vertical groove 23 formed in the end of an insulating block 21 having a central cylindrical recess 24, whereas the mean position of the magnet is horizontal and its motion to either side of that position is limited by a pair of adjustable stops 42 (only one shown). As shown in Fig. 4, the magnet 35 in one of its limit positions is displaced from the vertical by an amount greater than the armature 31 and hence the armature is held by magnetic attraction against the walls of the groove 23. Clockwise movement of the magnet through 90 degrees to its other limit position upon rising of the float causes a steady diminution of this attractive force which passes through zero and then increases in the other direction, whereby the armature is snapped through the vertical to its other displaced position in which it is similarly held by magnetic attraction against the groove walls (Fig. 5, not shown). A rotor 25 mounted on the spindle 26 within the recess 24 carries, within a circumferential groove 45, a pair of diametrically opposite contact rollers 48. The rollers are waisted and the waists are engaged by a resilient ring 49 disposed in the groove 45 to urge the rollers against the wall of the recess 24 whereby in each of the two limit positions of the armature each roller makes or breaks contact with a respective pair of fixed contacts embedded in the block 21, the fixed contacts having surfaces flush with the wall of the recess and being situated at the roller ends (Fig. 2, not shown).

Patent GB-666211-A (GB)
Title: Improvements in lubricating oil composition
IPC: C10M135/00
Filed: 1948-02-05
Abstract: A lubricating composition, especially suitable for use in the crank cases or gear cases of automobiles and in the metal working industry, comprises a major proportion of a mineral lubricating oil, a minor proportion of a stable oil-soluble extreme pressure addition agent and a minor proportion of an oil-soluble corrosion inhibitor comprising a sulphur-bearing amine containing only the elements carbon, hydrogen, sulphur and nitrogen.  The E.P. addition agent has a vapour pressure less than atmospheric at 140 DEG C., substantially increases the load-carrying ability of the lubricating composition and is dependent for its effectiveness on its ability to react chemically with the metallic surfaces to be lubricated.  The corrosion inhibitor is one characterized by the fact that its inclusion in the lubricating composition does not substantially decrease the extreme pressure properties imparted to the composition by the E.P. addition agent.  The corrosion inhibitors mentioned are thioamines, including aryl thioamines such as the thiophenylamines, and particularly thiodiphenylamine.  E.P. addition agents mentioned are (a) halogenated aliphatic compounds such as C Cl4, C2 Cl4, C2 Cl6 C2HCl3, C2HCl5, (C2H4Cl)2O, C17H33Cl2COOH, and halogenated petroleum fractions, particullarly chlorinated paraffin wax (b) halogenated cyclic organic compounds such as naphthalene tetrachloride, dichlorodihydrobenzene (C6H6Cl2), tetrachlorotetrahydrobenzene (C6H6Cl4), hexa-chloro-cyclohexane, monochloro addition product of diphenyl ether (C12H10ClO), dichloro addition substitution product of diphenyl ether (C12H9Cl2O), nonochloro addition substitution product of diphenyl ether (C12H7Cl9O), pentachloro addition substitution product of diphenyl ether (C12H6Cl5O), chloro-benzoic acid, chloronitrobenzene, benzyl chloride and phenyl ethyl chloride, (c) organic poly-sulphides, (d) substances of the formula RNH2.  H2S where R is an organic group, (e) sulphur chloride-treated oils (whether mineral or non-mineral) and fatty acids, (f) free sulphur, (g) fatty acids such as oleic and stearic acids, naphthenic acids and halogen-bearing substitution products of such acids.  The lubricating composition may also contain soaps, pour-point depressors, anti-oxidants, oiliness agents, non-mineral oils and fatty acids such as oleic acid.  In an example, a mineral lubricating oil composition is described containing benzyl chloride and thiodiphenylamine.  The Specification as open to inspection under Sect. 91 refers to the use of benzyl thiocyanate, thiourea, thiocarbanilide and other nitrogen and sulphur-containing compounds as the corrosion inhibitor.  This subject-matter does not appear in the Specification as accepted.

Title: Purification of n, n-bis-(dehydroabietyl) alkylene diamine penicillin
IPC: C07D499/00
Filed: 1956-02-02
Abstract: Substantially pure penicillin salts of N,N1-bis-(dehydro-abietyl) alkylene diamines in which the alkylene has up to 8 carbon atoms in the molecule are prepared by subjecting a mixture containing a major proportion of a penicillin salt of an N,N1-bis-(dehydroabietyl) alkylene diamine and a minor proportion of a penicillin salt of a N,N1-bis-(dihydroabietyl) alkylene diamine and/or a N,N1-bis-(tetrahydroabietyl) alkylene diamine to intimate contact with a solvent comprising essentially n-butanol, allowing the said penicillin salts to remain in contact with the said solvent until precipitation of the desired penicillin N,N1-bis-(dehydroabietyl) alkylene diamine occurs.  It is preferred to mix a solution of the mixed dehydro-, dihydro- and tetrahydro-abietyl alkylene diamines in n-butanol with a solution of a penicillin acid in n-butanol or chloroform, when the penicillin alkylene diamines form in situ, and allow to stand at e.g. 5 DEG  C. in order that the N,N1-bis-(dehydroabietyl) alkylene diamine dipenicillin may crystallize, the dihydro- and tetrahydro-compounds remaining in solution.  Alternatively, crude N,N1-bis-(dehydroabietyl) alkylene diaminedipenicillin may be purified by crystallizatio from n-butanol solution.  The penicillin may be penicillin G, penicillin O, penicillin F, penicillin X, penicillin K or other penicillin including biosynthetic penicillins.  In one example, there is described the preparation of N,N1 - bis - (dehydroabietyl) ethylene diamine di penicillin G.  Pure N,N1-bis-(dehydroabietyl) ethylene diamine is obtained by treating N,N1-bis-(dehydroabietyl) ethylene diamine dibenzyl penicillin in chloroform water solution with sodium carbonate to pH 9.5.  The dehydroabietyl ethylene diamine passes into the chloroform layer which is separated and the solvent removed.  The dihydrochloride is obtained by treating the residue with methanol hydrochloric acid.  Specification 753,739 is referred to.ALSO:Substantially pure penicillin salts of N,N1-bis-(dehydroabietyl)alkylene diamines in which the alkylene has up to 8 carbon atoms in the molecule (see Group IV (b)) are employed in pharmaceutical preparations.
