Title: Improvements in and relating to automatic telephone or like systems
IPC: H04Q1/34
Filed: 1940-06-19
Abstract: 542,010. Automatic exchange systems. HEPTINSTALL, D. L. June 19, 1940, No. 10561. [Class 40 (iv)] A code-translating register-sender comprises a member which is set by trains of impulses or by marking from a keyboard to select a mechanical linkage characteristic of the translation required, the number of trains and the number of impulses in each train being determined by stop control. Construction. As shown in Figs. 1, 2, a rotary drum A which can be set to one of 100 positions by means of tens and units stepping magnets TM, UM acting on ratchet - wheels 11, 12 is provided on its periphery with rows of holes 13, a number of pins B of varying lengths being inserted in each row in accordance with the various translations. The sending-control mechanism comprises a sleeve 17 which is moved axially along a shaft 16 by means of a stepping magnet 22 as impulses are transmitted until a feeler 23 strikes the first pin of the selected row, whereupon impulsing ceases, a magnet 24 operates to restore the sleeve axially and a rotary magnet 25 operates to rotate the sleeve through one step to bring the feeler 23 opposite the next pin of the row. It is arranged that the first impulse that steps the sleeve 17 is not sent out, and when the transmission is completed, the feeler 23 engages an extra long pin after a single step of the sleeve to operate a release magnet 26. In a modification, Figs. 4, 7, the drum is replaced by a pair of circular discs 30, 31 which are provided with radial slots for receiving plates 24, these being held individually or in groups by latching springs 37, 38. Each plate is formed on its outer side with stepped slots which co-operate in succession with the feeler 23. Circuits, Figs. 8, 9. The incoming trains of impulses are directed by relay RA to the tens and units magnets TM, UM, and when reception is complete, the relapse of series relay RC connects up RTN to start transmission. Impulses from springs GD are repeated by RHS to the magnet 22 to step the sleeve 17, and after the first step springs NP2 open and allow subsequent impulses to be sent out from springs LP. The engagement of the feeler 23 with a pin B is detected by relay SXM, which causes restoration of the sleeve 17 by the magnet 24 and its rotation through one step by the magnet 25. The inter-train pause is measured by the relapse of sluggish relays RO, PA. When the last train has been sent, the feeler 23 strikes a pin after a single step and relay RLS energizes before springs NP2 change over, operating the release magnet 26. Modifications. The drum A may be set by a number of trains of impulses other than two, and it may be power-driven under control of the impulses. A number of translations may be provided in each position of the drum, one being selected by an additional impulse train. When controlled from a keyboard, the drum may carry a wiper moving over contacts adapted to be marked by the keys. The translations may include metering impulses as well as a routine number.

Title: Improvements in orgí¡í¡ compounds
IPC: C07F7/00
Filed: 1961-03-23
Abstract: Organic lead compounds are prepared by heating lead monoxide, lead hydroxide or lead carbonate under substantially anhydrous conditions with an alcohol or phenol which is liquid at the reaction temperature, the alcohol being a saturated straight or branched chain primary aliphatic alcohol containing one or two hydroxy groups which may be substituted by a phenyl group, or secondary butanol, or a saturated cyclic aliphatic alcohol and the phenol being either substituted or containing a substituent which is not reactive under the reaction conditions. The products give some of the reactions of alkoxides and aryloxides but contain in some cases a higher percentage of lead than required by such compounds.  The products may be heated with an alcohol, phenol, amino alcohol, amino-phenol or acid of higher boiling point than the initial alcohol or phenol to give a higher boiling lead compound.  The reaction may be carried out by heating the reactants under reflux and separating the water formed.  If desired an inert liquid may be added to the mixture to entrain the water formed. Examples are given of the formation of lead compounds from 2-ethyl hexanol, nonanol, lauryl alcohol, cyclohexanol, phenol, p-octyl phenol, benzyl alcohol, n-hexanol, ethylene glycol, cetyl alcohol, salicyl aldehyde, bisphenol, n-butanol, i-butanol, and sec-butanol. In addition some of the products are further reacted with lauric acid, stearic acid, maleic acid, monononyl phthalate and monononyl maleate to give lead salts and with oleyl alcohol, octadecanol, monomethanol, diethanolamine and triethanolamine to give the corresponding lead alcoholates.

Abstract: 354,338. Utilizing solar heat. JUSCHENKO, M. M. K., 4, Twerskaia, Jamskaia, Moscow. April 4, 1930, No. 10713. Convention date, Dec. 20, 1929. Drawings to Specification. [Class 64 (ii).] A liquid of high-boiling point, e.g. amyl alcohol, is vaporized by solar heat, and the vapour employed to heat water or generate steam. The water is preheated in absorption chambers arranged in layers alternately with layers of evacuated glass cells, or of glass plates, with a reflecting coating. The high-boiling liquid is vaporized in somewhat similar chambers, which may be coated on the bottom with a black absorbent layer. The vapour of the high-boiling liquid may be passed through a heat-storing substance, so that when solar heat is lacking, the heat storing substance may supply heat to the high-boiling liquid which is then employed to heat water in steam boilers. Liquids of low-boiling point, e.g. ammonia or ethyl alcohol may be used in the boilers. A detailed description of the absorption chambers, glass cells, and the arrangement of plant for a power system is given.

Abstract: 200,595. Wood, H., and Norman, J. M. April 18, 1922. Steam-engine and like indicators; pressure and vacuum gauges; indicating- means for; with recording apparatus.- Means for indicating or recording high speed cyclic variations of pressure, or maximum or minimum pressures, for instance the cylinder pressures in internal combustion engines, com. prises an electric circuit in which a spark occurs when a light contact-breaker is moved by the difference between the pressure to be measured and a separate increasing or decreasing fluid pressure of known value. A cock casing 11, Fig. A, is adapted to be secured to the cylinder head of an internal combustion engine and contains a light contact disc 13 having a limited movement between contacts 14, 15. The cylinder pressure acts on one side of the disc 13 and a slowly increasing or decreasing pressure acts on the other side of the disc the fluid being supplied through the pipe 16 from a compressed air container 19, Fig. 3, or from a pump. The pipe 16 is connected to a pressure distributor 17 which is also connected by a pipe 22, of length equal to the pipe 16, to two pressure gauges 23 through a cock 32. The disc 13 is in circuit wich the primary 27 of an induction coil which is earthed together with the contacts 14, 15. The needles 29 of the pressure gauges are earthed and their points move near a metal ring 28 in the secondary circuit of the induction coil. The curve x, Fig. 1, denotes the cyclic variation of pressure and the line a b c d - - the gradually increasing pressure. At the points a, b the disc 13 will be moved from the. contacts 14 to contacts 15 and a spark will pass between the pointer and ring on the gauge. As the needle moves around the scale sparking will cease when the gradually increasing pressure just exceeds the maximum pressure. Two gauges 23 and a change-over switch 32 are provided, one gauge for explosion pressures and the other for compression pressures. Fig. 7 shows a recording form of the invention. The distributor 17 is connected to' À the container 19 or pump 21 and the pipe 22 leads to a cylinder 24 fitted with a fluid-tight piston 42. This piston works against opposed compression springs 33 and outside tension springs 34 and is connected by levers 35, 36 with a link 37 one end of which moves over a paper carrying drum 31, the other end sliding in an insulated guide 40. The drum is driven in phase with the cylic pressure change and the paper is perforated by a spark producing a diagram made up of the points a b, c d, e f, &c. superposed'. For recording the heavy compression and explosion pressures both sets of springs are used, but for the suction and exhaust strokes, the compression springs only are used.

Abstract: 781,803. Electrolytic removal of oxygen impurity from metals. HORIZONS TITANIUM CORPORATION. April 18, 1955 [April 26, 1954], No. 11119/55. Class 41. At least a major portion of the oxygen present as an impurity in the metals titanium, zirconium, vanadium, molybdenum, manganese, or chromium, is removed by anodic electrolysis in an electrolyte containing carrier ions of the said metal at a voltage below that at which anodic oxidation occurs, the oxygen being transported to the cathode leaving the purified metal at the anode. The impure. metal may either be directly charged into and and rest on the bottom of the bath container connected as anode or if of massive pieces it may itself form the anode. The applied potential should be below 2 volts. The electrolyte may be an aqueous solution or a solution in an organic solvent having no labile hydrogen of a halide, double halide, anhydrous nitrate or sulphate of the metal to be purified or a fused halide salt bath. Typically a fused bath containing sodium chloride and a double fluoride of potassium and titanium (K 2 TiF 6 ) is electrolysed at 800‹ C. using a graphite cathode on which a small amount of titanium having a high oxygen content is deposited, the anodically connected metal having its oxygen content reduced from 0.5 to 0.1 per cent. Similar processes employing potassium fluozirconate and fluochromate in place of the fluotitanate are described for removing oxygen from zirconium and chromium.
