Title: Improved esterification process
IPC: C08K5/10
Filed: 1957-10-15
Abstract: Esters suitable for use as plasticizers are prepared by reacting a dicarboxylic acid or anhydride with a C6-13 branched chain alcohol, the alcohol being present in an amount from substantially stoichiometric quantities to not more than 5 wt. per cent in excess thereof, in the presence of from 4 to 8 wt. per cent, based on the total theoretical quantity of ester, of an acid esterification catalyst, at 150 DEG  to 200 DEG  C. for a time sufficient to effect at least a 96 per cent conversion.  The alcohols are preferably oxo alcohols especially oxo octyl, decyl and tridecyl alcohols.  The dicarboxylic acid or anhydride generally contains 4 to 12 carbon atoms, e.g. phthalic, adipic, azelaic and sebacic acids and anhydrides.  Catalysts mentioned include sulphuric acid and organic sulphonic acids such as benzene, toluene and naphthalene sulphonic acids. Azeotrope-forming compounds may be present as water-entrainers, e.g. low-boiling aromatics such as benzene, toluene and xylene, paraffins such as heptane and octane, either n- or branched, or olefinic materials such as diisobutylene or codimer.  An oxygen-free atmosphere, e.g. CO2 atmosphere is desirable. Examples describe the preparation of ester from phthalic anhydride, azelaic acid or adipic acid and oxo isooctyl or decyl alcohol in the presence of p-toluene sulphonic acid and toluene in a CO2 atmosphere.

Filed: 1959-09-22
Abstract: 892,324. Soil irrigation. FOOD MACHINERY & CHEMICAL CORPORATION. Sept. 22, 1959 [Oct. 13, 1958], No. 32203/59. Class 33. [Also in Group XXIX] An irrigating system comprises a conduit 11a means supplying water pressure thereto, e.g. a pump, means for temporarily reducing the pressure, e.g. a timing device, a series of valves 12 spaced along the conduit, water discharge means 54 associated with each valve, a valve member 50 closing communication between the valve and the downstream conduit when flow starts in the conduit, the flow then passing to the discharge 54, and valve actuating means 46, operative on reduction in water pressure to re-establish communication with the downstream conduit. Initial upstream pressure at D seats the loosely hanging rubber ball 50 on seat 53 to close the downstream conduit and the water then flows to spray nozzle 54. Pressure then raises rubber membranes 44b, 40 on either side of rigid plate 38, forces a contained liquid 45a through plate orifice 52 from below to above the plate and stretches rubber stem 46 connecting the ball to membrane 44b. When a manual or automatic timing device momentarily reduces the upstream pressure, stem 46 drags ball 50 off its seat 53 into a position within lateral spray pipe 28 limited by a rigid tube 47 around stem 46 whereby on the return of upstream pressure, the ball closes the spray nozzle 54 and water passes downstream to the next valve, When all the valves have been actuated, the upstream pressure is shut off, membrane 40, or a spring returns liquid 45a to below plate 38 and the ball hangs loosely within conduit 11a.

Abstract: 662,425. Sanitary closets. ROCA, M. G., and ROCA, F. G. Dec. 16, 1949. No. 32345/49. Class 26. In a water closet seat or cover adapted to be lifted automatically in a controlled manner when relieved of pressure the seat or cover 1 is provided with a fixed crankshaft which is coupled, by a connecting-rod 7 to an operating-rod 10 having a loose piston 11 mounted thereon under the pressure of a spring 12. The piston 11 &c. operates in a cylinder 4 having a byepass 18 the effective passage of which is adjustable by means of a needle valve 9, the whole arrangement comprising a dash-pot. When the seat 1 is lowered and held down the piston 11 is raised in the cylinder 4 thereby compressing the spring 12 and the fluid above the piston 11 flows, in a retarded manner, to the underside of the piston 11 by means of the byepass 18 and ports 19, 20 in the piston 11 and operating-rod end the pressure unseating the ball valve 15 against its spring 16. When the seat 1 is no longer held down the spring 12 gradually raises the seat, the fluid meanwhile passing from below the piston to above it by means of the byepass 18. If the seat 1 is rapidly raised by hand the operating-rod end passes below the piston thereby uncovering the ports 19 whereupon the spring 12 presses the piston 11 on to the rod end as shown in Fig. 3.

Title: Electronic fuel control for a gas turbine engine
IPC: F02C9/28
Filed: 1974-07-24
Abstract: 1520882 Automatic control of speed LUCAS INDUSTRIES Ltd 21 July 1975 [24 July 1974] 32637/74 Heading G3R In a gas turbine engine control system, an engine speed error is limited in accordance with engine operating parameters, integrated, compared with the actual engine speed and the result used to control the engine fuel flow. The comparator output is differentiated and used to give an indication of engine surge whenever the rate of change of the comparator output exceeds a predetermined value for a given period. As shown, the speeds of main and free spools 11, 12 of the turbine are measured and compared with desired values as set manually at 13, 14. The lowest of the resultant speed errors passes through a lowest wins device 19, is limited at 20 according to the measured main spool speed and ambient pressure, and integrated at 21. The integral is compared with the actual main spool speed to form a signal D that controls the fuel flow to the engine. The signal D is also differentiated at 24 and compared with a reference from function generator 9, which also determines the limits for limiter 20. AND gate 28 receives the result of the comparison, and signals from comparator 29, both directly and via a monostable circuit 27, whenever the speed error from lowest wins device 19 exceeds a pre-set value, Vref. Provided the rate of change of D is greater than the reference from generator 9, the speed error is greater than Vref and of a duration longer than the unstable period of circuit 27, AND gate 28 provides an output which passes via delay 31 to monostable circuit 30. The output of this circuit is used to modify the main spool desired speed value for engine surges, so that the integrator 21 reverses in direction and the engine is decelerated for a period set by the unstable period of circuit 30. The unstable period of monostable circuit 27 ensures that the speed control is not modified at the start of an engine accelerating period.

Title: Improvements in or relating to the manufacture of margarine
IPC: A23D7/01
Filed: 1955-11-16
Abstract: In making margarine having diminished tendency to viscosity variation with temperature variation, there is incorporated in the margarine oil, fat or oil and fat mixture not more than 10% of a water-insoluble ester of a polysaccharide with a fatty acid of 8 or more carbon atoms, which ester forms non-sticky, thixotropic dispersions with water, and, when dissolved in an oil to the extent of 2% by weight, increases the oil viscosity at 20-35 DEG C. by at least four times.  Examples of such esters are starch esters such as starch stearates, preferably of the amylose of starch, and cellulose esters, especially of cellulose depolymerized to mol. wt. 50,000-200,000.  An example is concerned with dissolution of 2% of amylose stearate in margarine prepared by emulsifying water, lecithin and glyceryl monostearate in a fish oil, palm kernel oil and cottonseed oil mixture by stirring at 32 DEG C., cooling in ice water with stirring, and kneading.
