Title: Method for preparation of ethers
IPC: C07C43/04
Filed: 1976-05-03
Abstract: 1493754 Preparation of ethers TEXACO DEVELOPMENT CORP 3 May 1976 [6 June 1975] 17971/76 Heading C2C [Also in Division C5] A method of preparing an ether from an alkane hydrocarbon charge containing normal butane comprises: (a) isomerizing the charge to form an isomerate containing isobutane and n-butane in a weight ratio of from 1 : 1 to 2 : 1; (b) dehydrogenating the isomerate, thereby forming a dehydrogenate containing isobutene and n-butane in weight ratio of 1 : 1 to 3 : 1; (c) reacting the dehydrogenate with at least one water-soluble alcohol in the presence of an etherification catalyst thereby forming a reaction mixture containing product ether, watersoluble alcohol and n-butane; (d) contacting said reaction mixture with water thereby forming (i) an aqueous extract containing watersoluble alcohol, and (ii) a raffinate containing normal butane and product ether substantially free of said water-soluble alcohol; and (e) recovering said raffinate. The isomerization may take place for example at 310‹-375‹ F., 300-700 p.s.i.g. in the presence of hydrogen, using as catalyst alumina, which may contain Pt, Pd, Rh or Ru, and which is activated with chlorine or bromine and an inorganic sulphur compound of C 2 Cl 4 . Dehydrogenation may be carried out over a 15-25% chromium-on-alumina catalyst at 900‹ F.- 1100‹ F. The etherification may be carried out using a sulphonated resin as catalyst; the alcohol may be mono- or polyhydric, methanol being preferred. The hydrocarbon charge is for example n-butane, or a mixture of n-butane and n-pentane. Using the latter mixture, isopentane is produced as well as isobutane in the isomerization; unreacted n-pentane is preferably removed before the dehydrogenation, which yields isopentene as well as isobutene; the etherification using methanol gives a mixture of methyl t-butyl ether and methyl t-amyl ether which is recovered in the raffinate. A composition comprising 40-70 parts by weight methyl t-butyl ether and 50-90 parts by weight methyl t-amyl ether is claimed as novel; there may be present in the composition 10- 500 parts of a diluent which is a suitable component for incorporation into a gasoline, or up to 2200 parts by weight of gasoline. The compositions with gasoline are suitable for use as motor fuel.

Title: Improved method of and apparatus for plucking leaf from tea bushes and the like
IPC: A01D46/04
Filed: 1950-07-19
Abstract: 673,306. Tea leaf harvesters. LINDSAY, W., and THOM, R. P. July 19,1950 [Dec. 3, 1949], No. 18071/50. Class 6(iii) Leaves are plucked from a tea bush by apparatus comprising a rotary impeller 1 for sweeping mature-shoots against severing means 5, a roller 3 so positioned between the severing means and the impeller as to cause the stems of the shoots to be stretched against the severing means by the impeller drawing the tops of the shoots through the nip formed between the impeller and the roller, and means for rotating the impeller. In the construction shown the machine comprises a frame 14 having bearings 8a for the shaft 8 of the paddle wheel 1, the shaft being fitted with a cam 9 and a driving handle 7. The cam serves to impart intermittent rocking movements to a lever 10 pivoted at 10a, and this lever transmits such movements to another pivoted lever 11 driving a cutter knife 5. Associated with the knife are upper and lower plates 5a, 5b, a spring 12, and a rubber guard strip 6. In use, the machine is held in relation to the mature shoots A and immature shoots B as shown in Fig. 1. , Rotation of the handle 7 causes the resilient pads 2 of the paddle wheel to bend over the shoots A to be gripped between the pads and the roller 3. Such action causes the stem to overcome the resistance offered by the strip 6 and to come into the range of the knife 5 which is reciprocated by the cam 9 at the appropriate moment to sever the stem. The immature shoots are bent over by the strip 6. In a modification a machine carried by two operators shears a bush, and in another modification a power driven machine running on wheels or skids is employed.

Title: Improvements relating to the supply of air and combustible mixture to the cylinders of internal combustion engines
IPC: F02D9/00
Filed: 1930-06-16
Abstract: 360,931. Four-stroke-cycle engines; regulating. DAVIS, -J. R., 522, South 7th Street, Clarksburg, West Virginia, U.S.A. June 16, 1930, No. 18392. Convention date, July 5, 1929. [Classes 7 (ii) and 7 (vi).] A stratified charge is formed by admitting air only during the first portion of the induction stroke, and in such a manner as to obstruct initially' the extrance of a fuel and air mixture ; air and a mixture which may be non-explosive, are then induced until the air supply is cut off, following which an explosive mixture is admitted during the remainder of the stroke. A common inlet valve 11, Fig. 4, admits air and mixture through concentric ports terminating in valve seats 13, 14; during the initial opening movement of the valve the depression in the mixture manifold 8 causes air to flow from the manifold 9 into the manifold 8 towards the carburetter to an extent determined by the throttle position and cylinder pressure. The air supply is controlled by an engine-driven distributing valve, Fig. 13, comprising a casing 50 having an air inlet 52, a ported disc 54 driven by a shaft 26 at half engine speed, and air outlets 15, 151 leading to the air manifolds 9. A fan 57 for increasing the air pressure may be mounted on the shaft 26 which shaft may also drive the ignition distributer. An adjustable ported disc 58 controlled by an arm 35 may be provided to regulate the period of air admission, whilst ports 61 in a fixed disc are so located as to ensure that the air valve opens simultaneously with the inlet valve 11; when the regulating disc 58 is employed the period of opening is adjusted by varying the point of cut off, the arm 35 being coupled by a rod 41 to the throttle control pedal 40. The control rod 41, Fig. 15, is formed in two portions ; the portion attached to the pedal is fixed to a piston 44 carried in a slidably mounted cylinder 43, to which the adjacent end of the other portion of the rod is attached. The arm 35 is spring-loaded to cause the valve to close against the action of the pedal 40; on releasing the pedal to close the throttle the depression in the manifold 2 is transmitted by a flexible pipe 45 to the cylinder 43 causing'the latter to move to open the valve to admit air when the engine is running with closed throttle, as during coasting. According to a modified construction the air valve may comprise three concentrically arranged ported sleeves in place of the discs 54, 58, 61, the air entering a chamber formed by the innermost sleeve and leaving through diametrically opposed outlets corresponding to pipes 15, 15<1>. In place of the concentric air and mixture admission ports, separate valves arranged side-by-side may take the place of the inlet valve 11, a lateral passage communicating between the ports to permit a preliminary flow of air into the mixture manifold.
