Title: Means for indicating the level of the liquid in tanks, more particularly tanks of motor vehicles
IPC: G01F23/16
Filed: 1927-08-22
Abstract: 276,373. Paproth, J. Aug. 21, 1926, [Convention date]. Addition to 259,218. Indicators actuated by pressure of head of liquid.-In a device for indicating the level of liquid in the fuel tank of a motor vehicle as described in the parent Specification, the fuel is supplied to a carburetter 3 below the tank 1 through an enlargement 5, the air space of which is connected through a pipe 8 to a gauge 9. To reduce the pressure effect due to the velocity of flow, the pipe 2 is enlarged at 2a so that the rate of flow is diminished at the point where the vessel 5 communicates with the pipe 2 through the openings 7. A thread-way valve 4 is provided, so that the vessel 5 may be placed in communication with the atmosphere as in Fig. 2 to ensure that the vessel 5 is filled with air down to the openings 7. In modifications, the openings 7 may be placed at a constricted part of the enlargement 2<a>, or they may be replaced by Pilot tubes, or the upper part of the pipe 2 may dip into the liquid in the vessel 5, the liquid then overflowing into the lower part of the pipe 2.

Patent GB-615117-A (GB)
Title: Improved lubricating oils and greases
Filed: 1946-07-25
Abstract: Mineral lubricating oils and lubricating greases having extreme pressure properties contain small proportions, e.g. up to 1 per cent by weight, of thioacetals (mercaptals) obtainable from the reaction of chloral or chloral hydrate with one or more mercapto compounds, if necessary with the aid of heat.  The thioacetals may be represented by the general formula Cl3CCH(SR)(SR1), wherein R and R1 represent the same or different radicals, as for example alkyl, aralkyl, or aryl radicals which may contain substituents such as halogen, carboxylic acid groups, mercapto groups or thio-ether groups.  The thioacetals prepared from ethyl mercaptan, n-butyl mercaptan, isobutyl mercaptan, phenyl mercaptan, benzyl mercaptan, and mercaptans extracted from light petroleum spirits are said to be readily soluble in mineral lubricating oils, whereas thioacetal prepared from thiosalicylic acid is said to be very sparingly soluble.ALSO:Thioacetals (Mercaptals) are prepared by reacting chloral or chloral hydrate with one or more mercapto compounds, if necessary with the aid of heat.  The thioacetals may be represented by the general formula Cl3CCH(SR)(SR1), wherein R and R1 represent the same or different radicals, as for example alkyl, aralkyl or aryl radicals which may contain substituents such as halogen, carboxylic acid groups, mercapto groups or thio-ether groups.  The reaction between chloral or chloral hydrate and the mercapto compounds may be carried out in an aqueous acid medium and the resulting thioacetals frequently separate out in crystalline form.  In an example, one mol. of chloral hydrate is treated with two mols. of a mercapto compound and the mixture shaken.  Deposition of crystalline condensation products may be facilitated by the application of gentle heat, say to about 60 DEG  C.  Specified products are those obtainable from chloralhydrate and ethyl mercaptan, n-butyl mercaptan, isobutyl mercaptan, phenyl mercaptan, benzyl mercaptan, thiosalicylic acid or a mixture of mercaptans of boiling range 20 DEG  to 50 DEG  C. extracted from petroleum.  The products are useful as extreme pressure additives for mineral lubricating oils and greases.
