[Class 39 (i)] An electric discharge lamp having a gas or vapour filling which in normal operation of the lamp has a pressure of not much less than, and may be greater than, one atmosphere, has at least one of the electrodes mounted on a metal bellows which forms part of the sealed envelope of the lamp so that by deformation of the bellows the electrodes can be brought into contact and then separated to initiate the discharge. In the construction shown in the drawing the glass or quartz envelope 1 has two diametrically-opposed necks 2 and 3, to the outer ends of which are feather-edge sealed copper tubes 4 and 5, respectively, the tube 5 having hermetically sealed through its closed outer end 6 a tungsten rod electrode 7 and the end of the tube 4 being sealed to a thin-walled corrugated copper bellows tube 8 closed by a metal member 9. A tungsten rod electrode 10 is silver-soldered into a recess in the inner end of the member. 9 and is constrained to lie along the axis of the bellows 8 by a guide member 11 fixed inside the tube 4. The member 9 is controlled by a screw 12 working in a threaded recess therein, the screw 12 being mounted on a rigid framework 13, 14, 15, 16 surrounding the bellows 8 and rigidly attached to the tube 4 and being provided with a turning head 17 and a stop 18. Electrical connections 19 and 20 are made to bands 21 and 22 fixed to the tubes 5 and 4. The filling of the lamp may be argon or may be an easily condensable metal vapour, in which case the metal parts of the lamp may be thermally lagged and/or the metal parts may be provided with a heating coil.

Abstract: 866,610. Liquid fuels. TEXACO DEVELOPMENT CORPORATION. Oct. 6, 1958 [Oct. 11, 1957; Dec. 2, 1957 (3); Dec. 23, 1957; March 7, 1958; March 10, 1958; April 14, 1958; June 19, 1958; June 27, 1958], No. 31794/58. Class 91. A hydrocarbon fuel in the gasoline boiling range contains an organo-lead anti-knock agent, at least 10% volume of high octane components selected from olefinic hydrocarbons, aromatic hydrocarbons and mixtures thereof, and from 0.1 to 5% volume of one or more octane appreciators having the general formla: R<SP>1</SP>(X) n (R<SP>2</SP>) m COOR, [R<SP>1</SP>(X) n (R<SP>2</SP>) m CO] 2 O, or R<SP>1</SP>CHO wherein R<SP>1</SP> is hydrogen or a monovalent hydrocarbyl radical containing 1-29 carbon atoms, R<SP>2</SP> is a divalent hydrocarbyl radical containing 1-18 carbon atoms, R is hydrogen or a tertiary aliphatic hydrocarbyl radical containing 4 to 18 carbon atoms, X is R<SP>1</SP> being a monovalent hydrocarbyl radical when X is -O-, n and m are 0 or 1, where m is O and n is 1, X is only C=O, and the total number of carbon atoms in R<SP>1</SP>, R<SP>2</SP> and X is not more than 29. Effective appreciators are thus monocarboxylic acids of 1-30 carbon atoms, their anhydrides and t-alkyl esters and the ether- and keto-substituted derivatives of such acids, and also aldehydes. Many examples of all these classes of compounds are given. The fuel may contain additionally at least 0.1% volume of one or more arylamines having the formula R<SP>3</SP>NHR<SP>4</SP> wherein R<SP>3</SP> is a monocyclic aryl, a bicyclic aryl or alkaryl hydrocarbyl radical containing 6-16 carbon atoms and R<SP>4</SP> is hydrogen or a hydrocarbyl radical containing 1-12 carbon atoms. These amines, of which examples are given, are said to react synergistically with the octane appreciators to improve the octane rating of the leaded fuel. The aromatic and/or olefin content of the fuel can constitute up to 100% volume thereof but is usually between 20 and 80% volume. Organo-lead anti-knock agents specified are tetra-ethyl, -methyl, -butyl, -amyl, and -propyl lead. An ethylene chloride-ethylene bromide mixture is employed as scavenger.

Filed: 1957-10-11
Abstract: 877,887. Automatic exchange apparatus. GRASSO, L. Oct. 11, 1957 [Oct. 13, 1956], No. 31797/57. Class 40 (4). An alarm system which operates in response to the making of contacts associated with a push button or foot-switch, windows or doors, gas or temperature-sensitive elements or liquid level indicators, effects a connection to a predetermined exchange number and then preselectively transmits buzzer tone interrupted according to a distinguishing code, or one of three messages recorded on a magnetic track, a wax groove, or a gramophone disc. Actuation of a set of alarm contacts connects mains voltage to a power pack and a motor 2 which drives a turntable 15 and a set of cams 5, 7 and 10. When cam 5 moves off normal the connection to mains is ensured for one complete revolution of the cam shaft. When cam 7 moves off normal relay 26 is operated to make duplicate switch hook contacts associated with a telephone set 88. The turntable 15 comprises a plate, carrying disc 18, and a cylindrical skirt on the inside of which are projections 23, 33, which operate a duplicate set of dial off normal and impulsing springs 85 and 86. After a time interval sufficient to establish a call, cam 10 operates relay 76 to connect to the telephone exchange line the output of a buzzer 76 or of an amplifier 37 depending on the position of a manual switch. The buzzer winding 77 is in series with two wiper arms 40 engaging the bottom edge of the turntable skirt which by means of an apertured insulating strip interrupts the buzzer tone according to a code which identifies the call. The amplifier may be connected by means of a second manual switch to a pick-up head 35 reading a message recorded on a magnetic track 20 about the upper edge of the turntable skirt, or to a needle pick-up engaging a wax groove 28 near the centre of the turntable skirt, or to a pick-up arm 43 which reproduces the message on the disc 18. The messages on the magnetic track and wax groove will be repeated a number of times before the cam 5 returns home to disconnect the mains supply and by means of a cam 46 repositions the pick-up arm 43. If the alarm contacts remain closed the cycle will be repeated.

Title: A process for improving synthetic lubricating oils
IPC: C10G21/00
Filed: 1933-11-17
Abstract: Synthetic lubricating - oils obtained as described below are improved by extraction with selective solvents, e.g. nitrobenzene, aniline, acetonitrile, benzonitrile, chlorinated ethers, esters of aliphatic alcohols liquid sulphur dioxide, liquefied propane or other normally gaseous aliphatic hydrocarbon or mixtures.  Agents lowering the setting point may be added to the treated oils.  The synthetic oils are those made by polymerization or condensation of the liquid olefines produced by cracking paraffin wax or fats or fatty oils, or by dehydrating alcohols obtained by hydrogenation of fats or fatty oils; the olefines may be mixed with mineral or tar oil fractions, or cracking or destructive hydrogenation products of coals, tars, or mineral oils; and high molecular condensation products of isobutylene may be added before, during, or after condensation.  The extraction is effected by mixing and setting, or by countercurrent flow, suitably at -30 DEG  C. to 50 DEG  C. and if desired at increased pressure.  When the temperature is sufficiently low any contained paraffin wax separates from the oil and may be removed to improve the setting point.  For example, a lubricating oil obtained by the aluminium chloride condensation of a mixture of a cracking product of paraffin wax with German petroleum is treated with an equal weight of 2,2<1>-dichlorethyl ether; the viscosity index is raised from 104 to 115.
