Patent GB-476189-A (GB)
Title: Improvements in the manufacture and production of secondary, mixed aliphatic-cyclic alcohols
IPC: C07D307/42
Filed: 1936-06-26
Abstract: Secondary mixed aliphatic-cyclic alcohols are manufactured by treating, in the liquid phase, with hydrogen under a pressure of at least 20 atmospheres, preferably 100--200 atmospheres, in the presence of a hydrogenation catalyst containing metallic nickel, which may be distributed on a carrier, at temperatures between about 100 and 250 DEG  C., ketones which contain at least two rings in the molecule and in which the carbonyl group is not directly connected with a ring, e.g. unsaturated ketones formed by reacting aliphatic ketones, containing reactive alkyl groups, twice with aromatic aldehydes, such as dibenzylidene-, p-dianisylidene-, dicinnamylidene- or di-a -naphthylideneacetone, or analogous saturated ketones, or also unsaturated ketones formed by multiple reaction of cycloaliphatic ketones or of heterocyclic aldehydes with aliphatic ketones containing reactive alkyl groups, such as dicyclohexylidene- or bis-furfurylidene-acetone.  In many cases a preliminary hydrogenation of the olefinic double linkage may be effected.  The products are useful as perfumes, softening agents and additions to wax preparations, or for the preparation of assistants for the textile and related industries by the introduction of solubilizing groups, e.g. by the action of alkylene oxides or sulphonating agents such as chlorosulphonic acid.  In examples: (1) dibenzylidene-acetone is treated in methanol solution with hydrogen under 200 atmospheres pressure, first at ordinary temperature and then at 160 DEG  C., in the presence of a nickelchromium catalyst (prepared by treating a mixture of nickel carbonate and chromic acid with nitrogen at 300 DEG C. and then with hydrogen at 350 DEG  C.), to produce di-(cyclohexylethyl)-carbinol; dicinnamylidene-acetone similarly yields di-(cyclohexylbutyl)-carbinol; (2) bis-(p - dimethylaminobenzylidene) - acetone is treated in ethyl alcohol solution with hydrogen under 200 atmospheres pressure, at 160--170 DEG  C., in the presence of a nickel catalyst (prepared by precipitating nickel hydroxide on silica gel and reducing with hydrogen at 400--600 DEG  C.), producing bis - (p - dimethylaminocyclohexylethyl) - carbinol; p - dianisylidene - acetone similarly yields di-(p-methoxycyclohexylethy)-carbinol; (3) difurfurylidene-acetone is treated in ethyl alcohol with hydrogen under 200 atmospheres pressure, the temperature being slowly raised to 140--150 DEG  C., in the presence of the catalyst of (1), to produce di-(tetrahydrofurfurylethyl)-carbinol; (4) di-a -naphthylidene-acetone is treated in methanol with hydrogen under 50 atmospheres pressure, first at ordinary temperature and then at 160--170 DEG  C., in the presence of a nickel catalyst.

Abstract: 588,432. Fluid-pressure servomotors. LUCAS, Ltd., J., WATSON, E. A., and IFIELD, R. J. Dec. 16, 1942, No. 17894. [Class 135] [Also in Group XXVII] The supply of liquid fuel to a, prime mover is controlled by the blower-air pressure and the rate of flow of fuel measured by the relative movement of two members forming a variable orifice through which the fuel flows. The invention may be applied to the control of a variable delivery fuel pump, comprising a series of spring-loaded plungers c housed in a rotary member a and actuated by a swashplate e adjusted by a spring-loaded piston q. The piston is subject on one side to pump outlet pressure supplied through a conduit l and on the other side to a variable pressure regulated by a restriction t and a hinged leak-off valve w, loaded by a spring x. This valve is actuated by a diaphragm 2, adjustably located by a spring and subject to the delivery pressure of a centrifugal pump formed by an axial passage m and radial passages o in the member a. A second leak-off valve 16 is carried by a spindle 12, secured to a diaphragm 15, subject to blower-air pressure and loaded by a spring 13. The spring supports a plug 11 arranged in an orifice plate 9, between the main pump outlet j and the fuel delivery connection k, arranged so that the compression of the spring varies with the rate of fuel flow. In a modification, the valve 16 is replaced by a hinged valve, loaded by a spring adjusted by the movement of a tubular member about a tapered plug in the fuel conduit and actuated by an evacuated bellows and a bellows subject to blower-air pressure. The outside of the bellows may be subject to full pressure. According to the Provisional Specification, the spindle actuates the relief valve of a pump or a by-pass, or other regulating device in the fuel-supply system. Specification 577,016 is referred to.

Title: Improvements in or relating to diesel fuel compositions
IPC: C10L1/26
Filed: 1943-11-05
Abstract: To reduce deleterious deposits in Diesel engines, Diesel fuels contain a small proportion of a compound having the general formula MXY, in which M is a metal, X is oxygen or a member of the sulphur family, and Y is an organic radical, wherein the metal is attached through X to a carbon atom in the organic radical Y, which latter carbon atom in turn is connected only to carbon or hydrogen.  The principal classes of compounds described comprise phenolates, alcoholates, and the corresponding thio-compounds, and also thio-ether derivatives of phenolates, i.e., salts of hydroxy-aromatic sulphides of general formula M(O Ar)n (S)x where "n" and "x" are integers.  The preferred metal is one of the alkaline earth metal group.  The actual phenolate compounds specified comprise salts of alkylated natural and synthetic phenols such as calcium octadecyl phenolate, calcium di-isobutyl phenolate, calcium cetyl phenolate, barium salts of petroleum phenols, barium salt of cashew nut shell phenol (cardanol), and magnesium teramyl phenolate; and the thio-ether derivatives specified comprise barium di-isobutyl phenol sulphide and disulphide, barium octadecyl cresol sulphide, calcium diter-amyl phenol sulphide, cobalt hexyl phenol sulphide, and magnesium cetyl phenol disulphide.  The above compounds may be used together with other metal organic compounds such as metal derivatives of organic substituted phosphorus acids, their thio-derivatives, and sulphonates.  Other usual additives may be used particularly high aliphatic alcohols such as stearyl alcohol and phenolic ethers such as the ter-butyl ether of o-ter-butyl p-cresol.  The phenolate agent and the Diesel fuel may be supplied to the engine separately to mix before combustion.  The additives may also be present in the crankcase lubricant of the Diesel engine.  U.S.A.

Title: Improvements in or relating to means for indicating variations in the strength of a liquid current
IPC: H01J7/24
Filed: 1929-06-14
Abstract: 336,606. Dicker, S. G. S., (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). June 14, 1929. Tell-tale apparatus.-Variations in the strength of a liquid current are indicated by passing the liquid through a tube closed by a member which forms part of the magnetic circuit of an inductance coil, the reluctance of the magnetic circuit being modified in accordance with the strength of the liquid current. As shown in Fig. 1, the liquid current is led through a tube 2 closed by a valve 3 which is lifted more or less in accordance with the strength of the liquid current. The edge of the valve is provided with blades 8, causing rotary motion of the valve. A glass cylinder 9 is closed by brass covers 10, 11 clamped by bolts 12. Within the cylinder 9 are arranged coils 13 wound on laminated cores 15 and connected in series. The magnetic circuit of the cores 15 is closed by upper and lower annular yokes 16, each formed by coiling a silicon iron band. The coils 13 are enclosed in a brass cylinder 17 filled with a substance to protect the coils from the circulating liquid. The upper yoke 16 is carried by the valve 3, an airgap of variable width being formed in the magnetic circuit when this valve is lifted. By including the coils 13 in series with an ammeter and a source of current, the strength of a liquid current can be measured. Fig. 3 shows the application for stopping the working of a radio transmitting station if the strength of the current of cooling water to any valve becomes too small. The cooling water for each valve is passed through a variable inductance device 13 as described above, arranged in series with the secondary winding of a transformer 19, a measuning instrument 20, and the filament 25 of ai diode 21, the filament being shunted by a variable resistance 24. The diodes 21 are connected in series with a direct-current source 22 and a relay 23. If the cooling-water stream to any valve is insufficient, the tension across the shunt resistance 24 falls, the corresponding filament 25 is insufficiently heated, and the relay 23 operates to stop the working of the installation. The strength of liquid current at which this occurs can be adjusted for each valve by varying the resistance 24.

Abstract: 128,184. Rawlins, H. E. June 13, 1918, [Convention date]. Sunken ships, raising.-For locating a sunken ship H, Fig. 2, two vessels B, with a cable 3<1> dragging between them, steam along parallel courses until the cable is arrested by the submerged hull H. The ends of the cable can then be buoyed. To raise the ship, lifting cables 3, Fig. 1, are dragged by the vessels B under the bow and stern of the ship, the ends of the cables being carried up to lifting gear on pontoons 1 carrying a superstructure 2. A sleeve 7, Fig. 3, is placed over each lifting cable, each sleeve having mounted therein a cam-shaped lever 10. The levers of the two sleeves on one side of the ship are connected by a cable 12 somewhat shorter than the hull H, the levers of the two sleeves on the other side of the hull being similarly connected. The sleeves are lowered along the lifting cables by cables 9. When the lifting cables are raised, the cam-shaped levers are operated by the connecting cables 12 and grip the lifting-cables, preventing these from slipping away from the hull H during raising. The Specification as open to inspection under Sect. 91 (3) (a) states that, in locating the sunken ship, after the cable is arrested by the ship, the two vessels B continue to steam in the same direction and are thereby caused to swing together to the positions b, when they will be separated by a distance equal to one dimension, e.g. the length, of the submerged vessel. The two vessels B are then turned through 90 degrees and the process repeated, the vessels ultimately reaching positions c, separated by a distance equal to the breadth of the ship. The position of the ship can then be buoyed. This subject-matter does not appear in the Specification as accepted,
