Title: Process for improving the lubricating properties of hydrocarbon lubricating oils
Inventor: SHELLARD ARTHUR DONALD
IPC: C10M101/02
Filed: 1956-09-13
Abstract: A process for increasing the spreading pressure of an hydrocarbon lubricating oil on solid surfaces comprises treating the oil with not more than 1.5 per cent by weight of an organic peracid.  The oil may be any type of hydrocarbon lubricating oil such as a mineral oil derived from a naphthenic, paraffinic, or asphaltic crude petroleum or an aromatic extract.  Suitable organic peracids are those of fatty acids and substituted fatty acids and aromatic carboxylic acids, e.g. formic, acetic, propionic, butyric, monochloracetic, trichloracetic and benzoic acids.  They may be used as the preformed peracids or in statu nascendi by treating the oil with a mixture of the acid and hydrogen peroxide.  The treatment is carried out at ambient temperature and with good agitation is completed in from five minutes to three hours.  Residual acid, hydrogen peroxide and water are removed by washing with water or an alcoholic solution of an alkali, e.g. NaOH, Na2CO, or NH4OH or by treatment with solid alkaline material, e.g. lime, and filtration. The treated oils can be blended with other oils, e.g. fatty oils such as rape seed and lard oils and synthetic oils, e.g. polymerized olefins, alkylated aromatics, esters such as di-(2-ethyl hexyl) sebacate or adipate, alkyl and alkaryl esters of inorganic acids such as tricresyl phosphate or tetraoctyl silicate and polymers and copolymers of polyalkylene glycols and their ethers and esters and polyorganosiloxanes.  Other additives such as oxidation and bearing-corrosion-inhibitors, detergents, dispersants, pour-point depressants, V.I. improvers, anti-foam agents, rusting inhibitors, anti-wear agents, E.P. additives and dyes may be incorporated in the composition.  In all the thirteen examples, 100-volume hydrogen peroxide and the organic acid (formic, glacial acetic, propionic, butyric, monochloracetic or trichloracetic) are used to treat mineral lubricating oils.  The mineral lubricating oil may have been previously refined by a conventional treatment, e.g. with sulphuric acid or oleum; earth or lime; or a selective solvent such as sulphur dioxide, furfural or propane.  Specification 764,183 is referred to.

Title: Improvements in or relating to electric selective distant control systems

Filed: 1926-11-10
Abstract: 261,384. British Thomson-Houston Co., Ltd., (Assignees of Carter, E. F.). Nov. 10, 1925, [Convention date]. Selective distant control systems.- In a system for controlling the operation of switches group by group at will, and and for causing the operation of the switches in each group in a predetermined order as, for example, in the distant control of a rotary converter substation, the control is effected by imposing different frequencies on the line 1 all the relays of each group 3 - - 5 and 6 - - 11 being actuated through the intermediary of reeds 12, mechanically tuned to one of these frequencies and each relay being subjected to its own particular time-delay action to give the desired sequence of operation within the group. As shown, when a frequency of 25 cycles is imposed on the control lines 1, the reed 12 of the relay element 3 mechanically tuned to that frequency is set into vibration and serves to charge, from the source, 28 and through the resistance 29, a condenser 27 shunted by a resistance 30 so as to have an adjustable, time-constant. After a certain time, the voltage across the condenser becomes high enough to cause the thermionic valve 20 (to the grid of which it is connected) to pass enough current from the source 23 to operate the relay 24 and close the control contacts 25. Relays 4 and 5 operate similarly with the same frequency as relay 3 but have different time delays and relays 6 - - 11 operate with another frequency.

Title: Method of producing town gas or synthesis gas of low co-content by the gasification at elevated pressure of solid fuels
IPC: C10J1/207
Filed: 1960-08-16
Abstract: In a process for producing a combustible gas of low carbon monoxide content solid fuels are gasified at elevated pressure with a mixture of oxygen or oxygen-enriched air and steam and/or carbon dioxide and the gas produced is cooled and purified and then saturated with steam, reheated and reacted in the presence of a catalyst to convert some of the carbon monoxide with steam to carbon dioxide and hydrogen, the steam for the conversion being supplied by water circulating in a system comprising a saturator in which the gas to be converted is contacted with heated circulating water, a spray cooler and one or more indirect heat exchangers in which water from the saturator is partly reheated by heat from the converted gas and an indirect heat exchanger in which the circulating water is finally reheated before return to the saturator by the crude gas.  Heat for the conversion is supplied by heat exchange with the converted gas. The hot crude gas is first passed through a washer-cooler before entering the indirect heat exchanger in the water circulating system. The partially cooled crude gas after leaving the indirect heat exchanger is passed successively through a waste heat boiler, a regenerator regenerating potassium carbonate solution used to remove carbon dioxide from the converted gas, coolers, an oil washer and a washer in which hydrogen sulphide is removed before entering the saturator in which it is saturated with steam for the conversion. The surfaces of the indirect heat exchanger in contact with the crude gas may be continuously or intermittently flushed with condensate condensed from the crude gas.  In an example after scrubbing the converted gas to remove carbon dioxide the resultant gas had the composition: CO2 3.0%; CnHm 0.8%; Co 7.7%; H2 74.0%; CH4 13.1%; N2 1.4%.

Abstract: 192,157. Longmore, J. Oct. 27, 1921. Steam and other power cultivation.-Apparatus for drawing a plough &c. backwards and forwards between movable anchors by means of cables led around the field comprises two sets of blocks and tackles and special anchors, guide pulleys, and cable and block connections. Fig. 6 shows the arrangement of the apparatus. The two cables D pass through blocks B on the anchors A and one-way plough C and round guide-pulleys E at the corners of the field, the cables being drawn out by horses travelling backwards and forwards around the field, or by means of a two-drum winding-engine, or a horse-gear. The tackle may be so arranged that there are one, two, or more lengths of cable between the plough and anchor blocks, according to the power required. Two or more guide pulleys may be placed at each corner of the field. The anchor consists of one or more lengths of channel-iron or railway rail. Fig. 1 shows a method of fastening two lengths A of channel-iron together and pegging them down. A strap B is passed round the adjacent ends and fastened to them by loose pins B<1> and to the ground by a peg C. As the ploughing proceeds, the rear length is moved to the forward end. The rails or channels may rest on other rails or channels inserted in a trench or furrow. The pulleyblocks are connected to the rails A by hooks or by clips or stirrups secured by loose pins. Fig. 3 shows a corner guide pulley mounted on a steel tube G which is reduced in diameter at the end and twisted into the form of a screw so that it may be driven and screwed into the ground. The concave or flanged pulley H rests on a washer or ring K above a wooden or other block L sunk in the ground, and is prevented from rising off the spindle C by a pin J. The barrel of the flanged pulley shown is constructed of spaced bars I. Fig. 5 shows the connection between a cable and a pulley block. The eye or thimble E at the end of the cable is made small enough to pass through the block A, and the hook D that receives it is fastened to the block by a swivel C and split link B. A swivel is also provided at the other end of the cable.
