Title: Improvements in or relating to systems for use in connection with telephone lines
IPC: H04Q5/14
Filed: 1926-05-07
Abstract: 260,546. Lorenz Akt.-Ges., C. Oct. 31, 1925, [Convention date]. Automatic and semi-automatic exchange system.-A number of substations Z1 - - Z3, Fig. 1, spaced at intervals along an inter-exchange trunk, are called by characteristic Morse signals whilst the distant exchange responds only to a prolonged calling current or to an earthed calling current, the kind of calling signal to be transmitted over the trunk being determined by a controlling device, Figs. 2 and 3, which is associated at the outgoing end of the trunk and responds to one or more additional dialled digits. These additional digits, in the case of a call to an intermediate station, control also the transmission of the appropriate code, the digit 6 being used for a " dash " and the digit 2 for a " dot." When the trunk is taken into use, relay J completes a circuit for relay V which causes magnet DSt to move wipers St1, StII one step into position O<1>. Assuming now a call for an intermediate station characterized by a dash and a dot, the first extra digit 6 is repeated by relay J so that relay JV pulls up over wiper StII and the six impulses pass over contacts v1, iv3 to magnet DSt. At the end of the digit, wiper StII comes to rest on a dead contact, relay JV falls back and the switch is unable to move any further during the call. During the digit 6 relay R is operated to connect up ringing current PW, Fig. 3, for a corresponding time and during the subsequent digit 2, relay R is again operated over contacts i, v1, iv3, to give a short ring. The distant exchange is unable to respond to either of these rings owing to the slow-acting provision on the ringing-responsive relay. When it is desired to call the distant exchange, however, the dialling of digit 9 causes wiper StII to move to position 9 in which relay JV remains locked over its lower winding, and relay R is continuously energized. To stop the calling signal an additional digit 1 may be transmitted,or alternatively other digits may be transmitted so that the calling signal is repeated. To call the distant exchange by an earthed calling current, the digit 3 is used, when wiper StII energizes relay E which connects up the centre earthed winding of the transformer RU. Relay R is directly under the control of the calling party so that Morse earthed signalling may be employed if desired.

Filed: 1974-03-19
Abstract: 1427668 IC engines; turbine plant E H PHILLIPS and E D PHILLIPS 19 March 1974 12040/74 Headings F1B and FIT A combustion engine utilizes as working fluid the products produced by reaction of an alkali metal (such as sodium, lithium or potassium) in liquid form with water; the hydrogen in the reaction products being ignited by the heat of the reaction. The engine shown is of reciprocating piston type and comprises a storage tank 20 for the alkali metal in liquid form which is regarded as fuel, the fuel passing through pump 22 to an injector 24 which injects into the cylinder or reaction space C. Water is contained in tank 30 and is connected to a device 32 which produces a mixture or air and water which passes through induction line 37 and inlet valve 17 into the reaction space C; the engine also comprises an.exhaust valve 18 and outlet pipe 41 through which the exhaust, mainly steam, discharges to atmosphere. A further outlet 44 is provided from the reaction space through which the hydroxide of the reacted alkali metal discharges to a container 45. A portion of the hydroxide from outlet 44 may pass through line 49 into the engine crank-case for lubrication purposes, the hydroxide passing back to the container 45. As the piston moves downwardly the inlet valve is open and air and water mixture is drawn in. The mixture is compressed as the piston rises and towards the top of the stroke the fuel is injected through injector 24- the fuel reacts with the water and the hydrogen produced explodes, producing the power stroke followed by the exhaust stroke in which gaseous products are discharged through valve 18 and outlet 41. The hydroxide is discharged through the outlet 44 as the piston descends during the power stroke. The container F for the fuel, also the lines 21, 27, are heated so that the fuel is in liquid form. A quantity of hydrocarbon fuel 29 may be disposed in the container above the alkali metal. The working fluid may alternatively be used to drive a turbine.

Abstract: 372,538. Hydraulic transmission of power. McLEOD, R. J. and COCKBURN, D. H., of Power Plant Co., West Drayton, Middlesex. April 23, 1931, No. 12049. [Class 69 (ii).] In fluid-operated feed mechanisms for gear cutting and other machines, the rise of pressure occasioned by the arrest of the feed is utilized to cause the return motion, means being preferably provided whereby the return is not initiated until a predetermined interval has elapsed after the stoppage of the feed. In the form shown, a tool or work holder J is operated by a screw I from a rack G carried by a piston f, a control valve D determining the direction of motion. The valve D is initially set by a lever d<1> so that feed takes place until an adjustable stop j contacts with a fixed abutment. The consequent rise of pressure in a supply pipe 12 then moves a spring-pressed valve L to admit pressure to a cylinder M to cause a plate N to rise and carry a pinion O into engagement with a pinion O<1> on a driven spindle a. The pinion O has adjustable cam members t, q, the former being adapted to move the upper end of a latch Q into the path of the latter. When the latch is tripped by the cam q, a spindle r<2> is operated by a spring s and the valve D is moved into position for the return motion by quadrants R, R<1>.

Patent GB-662085-A (GB)
Title: Process of preparing acetals of acetylenic aldehydes and the products thus obtained
Filed: 1949-05-06
Abstract: Acetals of aliphatic alpha, beta-acetylenic aldehydes are made by treating an acetal of an aliphatic alpha-halo-alpha, beta-olefinic aldehyde with an aqueous solution of an alkali under superatmospheric pressure and at a dehydrohalogenation temperature above the normal boiling point of the aqueous alkali solution.  Preferably the desired aldehyde is continuously withdrawn in the vapour phase under pressure at a rate substantially equal to that of its formation.  Alkalis specified are alkaline alkali metal compounds, e.g. alkaline earth metal hydroxides, alkali metal carbonates and hydroxides, the latter being preferred, and ammonium hydroxide.  Sodium hydroxide is especially preferred.  The strength of alkali solution used varies from about 2 to 30 per cent and is preferably about 5 to 30 per cent. Preferably a moderate excess, e.g. at least 10 per cent, above the stoichiometric equivalent of liberated hydrogen halide is used. Preferably amounts from about 1.1 acid-equivalents upwards of alkali per mol. of olefinic acetal are used although larger amounts e.g. 10 mols. may be used.  Specified haloacetals are those of alpha-chloroacrolein, alpha-chlorocrotonaldehyde, alpha-bromo-, alpha-iodo-, or alpha-fluoro-acrolein and the acetals may be those of mono- or polyhydric alcohols, e.g. aliphatic, aromatic or cycloaliphatic alcohols, although those of the lower aliphatic monohydric alcohols are usually employed.  A pressure range of about 40 to 200 p.s.i.g. is preferred and the pressure is also preferably not below about 10 p.s.i.g. Temperatures indicated are at least about 110 DEG  C., preferably at least about 130 DEG  C. and not over about 190 DEG  C., although temperatures of up to about 220 DEG  C. are given.  Optimum results are obtained in the range of about 130-170 DEG  C.  Inert gases may be used to increase pressures.  In batch processes reaction times of 1 to 6 hours generally suffice, although those of not over about 3 hours are preferred.  In examples (1) and (3) the dimethyl, and (2) the diethyl acetal of alpha-chloroacrolein is treated with aqueous sodium hydroxide to yield the corresponding acetal of propargyl aldehyde and in (4) the dimethyl acetal of alpha-chloroacrolein is treated with aqueous potassium hydroxide to yield the corresponding acetal of propargyl aldehyde.  Acetals of alpha-halo acroleins are made by halogenating acrolein to the dihalopropionaldehyde and dehydrohalogenating the latter with boiling water to provide a distillable azeotrope of the alpha-halo acrolein which may be converted to the acetal by reaction with an alcohol at room temperature in the presence of a trace of acid and examples (1) and (2) respectively illustrate the preparation of dimethyl- and diethyl-acetals of alpha-chloroacrolein.

Abstract: 971,294. Gas blast switches. BROWN, BOVERI & CO. Ltd. March 28, 1963 [March 30, 1962; April 26, 1962], No. 12275/63. Heading H2B. Valves 111, 122 controlling the flow of blast gas to circuit-breakers, not shown, are located on live parts of the breakers and controlled from earthed parts thereof by insulating tensioned rods 110, 118, the valves being opened in the direction of flow by the pressure gas. The interior of insulators 112, 116 are in communication through 102 with a pressure gas reservoir. Application of high pressure to the underside of a piston 106 allows the pressure gas to force valves 111, 122 away from their seats to release blast gas to the breakers which momentarily open the contacts, series isolators effecting voltage insulation. In another embodiment (Fig. 1, not shown), the rods operate the valves, through suitable linkages, to supply pressure to pistons which open the contacts. Various arrangements are shown for controlling the insulating rods such as a differential piston (Fig. 1), a simple spring-biased piston (Fig. 2, not shown), an electromagnet (not shown), or the latching arrangement of Fig. 3 in which to open the breaker, a holding lever 36 is rotated, as by an electromagnetic trip, to release a member 34 from a latch 35 whereupon the pressure gas moves the rods as before. Closing is performed by applying pressure gas to a piston 40.
