Title: Process for the separation and recovery of methyl esters of lower aliphatic organic acids
Inventor: RIOCCI MARIO
IPC: C07C/
Filed: 1990-03-02
Granted: 1993-12-15
Abstract: A process for the separation and recovery of methyl esters of C2-C7 aliphatic carboxylic acids from an aqueous solution comprises the following stages: (a) extraction of the aqueous solution, at a controlled pH, with an organic solvent, especially kerosene, in which is dissolved trioctylphosphine oxide (TOPO), to obtain a solution of the said acids in the said solvent mixture; (b) addition of methanol to the solution of the acids obtained in stage (a) and holding under esterification conditions, in the presence of a heterogeneous acidic catalyst, in order to transform the acids to the corresponding methyl esters, operating in the absence of a separate aqueous phase; and (c) recovery of the methyl esters of the C2-C7 aliphatic carboxylic acids from the esterification products from stage (b). The aqueous solution of the C2-C7 aliphatic carboxylic acids can derive from the anaerobic acidogenic fermentation of the organic fraction of solid urban wastes. The methyl esters of the C2-C7 aliphatic carboxylic acids thus obtained can be used as high-octane additives for petrols, in replacement for tetraethyl lead, or as organic solvents.

Title: Ring spinning traveller - has one section to graze the fixed part of the assembly while the yarn is held clear of friction heat
IPC: D01H7/56
Filed: 1977-03-02
Granted: 1985-04-27
Abstract: In a ring spinning equipment, the traveller is given a particular shape, and is fixed by a keyed mounting into the rotary section of the spinning ring. One section of the traveller has a surface designed to graze the fixed part of the spinning ring. A further section, displaced from the grazing section, is shaped and arranged for the yarn to be wound to pass through it. The design gives an adequate braking action between the rotary and fixed sections of the assembly, so that the rotary section turns at a slower rate than the spindle, but holds the yarn clear so that it is unaffected by any friction heat which can develop.

Title: Wire electrode feeder testing - particularly for continuous weld wire
Inventor: DJANKO VESSELINOV TSCHANKOV
IPC: B23K/
Filed: 1975-01-17
Granted: 1978-09-20
Abstract: Wire electrode feed devices are tested by (a) unwinding the electrode wire from the rotating bobbin during the test as a result of the tractive force exerted by the feed device, which together with the bobbin is in a state of relative mobility w.r.t. both to the wire and the bobbin, so that during unwinding, the electrode wire and the feed device are subject to mechanical braking resistance balanced and measured by means of a force-measuring element acting equally on the relatively mobile feed device and on the wire resp. in the feed direction or vice versa, and (b) balancing the two forces to represents the force which the wire feed device can overcome as a consequence of the frictional force between the feed rolls and the wire electrode, permitting the test to be carried out with the simultaneous measurement of the thrust, the feed speed and irregularities in it. Tests of wire feed devices including those of planetary type can thus be carried out with a continuous wire electrode over a wide range of speeds, without risk of twisting or kinking of the wire and permitting determination of reliability and length of life.

Title: Compression chamber with exhausts through the piston and through the head
Inventor: CESARINO MOLARO
IPC: F02B/
Filed: 1989-09-12
Granted: 1992-07-03
Abstract: The compression chamber with exhausts also passing through the piston as well as passing through the head, in piston motors and in piston pumps and compressors, permits large sized exhaust valves and the construction of two-stroke motors which do not require the consumption of lubricant, nor the loss of fuel through the exhaust. The exhaust through the piston is achieved by a valve in the piston head, operated automatically by the movement of the piston itself; and thanks to a gas tight cylindrical duct inside the piston itself, made possible through the use of the "eccentric mechanism for crank machines" which allows having the piston constantly aligned and devoid of piston rods and pins. Every application is possible because, besides the head, even the cylinder inside the piston may be closed by a controlled valve, thus creating two compression chambers, communicating through the piston valve.

Abstract: A sealing composition for a container closure comprises a polymeric matrix material and is modified by the inclusion therein of an oxygen scavenger. The composition can be in fluid or meltable form ready for application to a closure or it can be present as a deposit on the closure, for instance a gasket around the closure. Preferably the scavenging properties of the deposit are activated by pasteurising or sterilising the deposit when sealing a container with the closure. The invention is of particular value when the closure is a metal cap for a beer bottle.
