Title: Improvements in and relating to ricinoleic esters of polyalkylene glycols
IPC: C07C69/52
Filed: 1959-02-27
Abstract: Hydraulic fluids comprise ricinoleic acid esters of poly alkylene glycols which esters alone or in admixture with glycerides or other esters, have been purified by treatment with cationic and/or anionic exchange resins to remove ionic and non-ionic impurities and then hot blown with a gas containing free oxygen (see Group IV(b)).  The fluids may also comprise mono- and polyhydric alcohols, mono- and di-alkyl ethers of glycols and other polyhydric alcohols, ketoneethers and ketone-alcohols. Extreme pressure additives may also be incorporated.  The admixture of the ricinoleic esters with ethylene glycol, diethylene glycol and poly-propylene glycols is also described. Specification 835,553 and French Specification 1,053,910 are referred to.ALSO:Ricinoleic acid esters of polyalkylene glycols are purified by passing them over cationic and/or anionic ion exchange resins for the removal of ionic and non-ionic impurities and subjecting the purified esters to hot blowing with a gas containing free oxygen such as air.  Suitably the gas is passed in a finely dispersed form through the ester at 120 DEG  to 180 DEG C.  The hot blowing results in polymerization occurring and promoters therefore may be present.  The esters may be used in admixture with glycerides or other esters.  The products may be used in hydraulic fluids (see Group III).  In typical examples: (1) castor oil is heated with polyethylene glycol (M.W.400) at 194 DEG C. under 2 mms. pressure in the presence of sodium as catalyst, the liberated glycerol being distilled off; the ester product is purified by passing a methanolic solution thereof over a cationic resin, an anionic resin and then a mixture of both resins; the methanol is thereafter distilled off and the ester is hot blown with air at 150 DEG C. and then neutralised with NaOH or alternatively again treated with cationic and anionic resin; (8) a ricinoleic ester prepared as in (1) is purified using a cation exchange resin only and then is hot blown at 170 DEG C. with air.  Caustic soda and benzene sulphonic acid are additional catalysts named for the esterification.  Specification 835,553 and French Specification 1,053,910 are referred to.

Each auxiliary belt passes over rollers situated between the upper and lower sides of the main belt and so disposed that the upper surface of the auxiliary belt is on the same level as the upper surface of the main belt. Each auxiliary belt runs between the halves of a divided bench and is preferably flush with them. Articles, such as trays T, are transferred from the belt MCB to an auxiliary belt by an arm TA supported above the plane of the belt which is engaged by a pin P on a tray The arms are supported at different heights, and pins of different lengths are provided, so that by the use of a particular pin, the deflection of a tray by a particular arm may be ensured. At the end of the auxiliary bench a similar arm TA deflects it on to the bench. After an operator has performed one operation on the article or articles on the tray, the tray is transferred to an operator on the other side by. a turntable TT1 provided with a shoot Ch and take-off arm. A series of turntables is provided for transferring the trays from one side of the bench to the other, and each turntable is driven through a flexible drive by a friction wheel in contact with the lower side of the auxiliary belt. The last operator places the tray on the main conveyer belt on the opposite side of the arm TA, and it proceeds to another bench for a further set of operations, or for inspection, or packing. The turntables on the bench B4 are arranged closely together, and articles are transferred from one table to the next by take-off arms TA2 fixed to the stationary spindles. A reservoir is formed at the centre of each table by. a rubber or metal wall CW. An approximately equal division of trays between the halves of the bench B3 is secured by providing a double takeoff arm TA3. The Specification describes the use of the system for the progressive assembly of resistances and for progressive coil winding.

H., 40, Murray Road, both in Rugby. March 8, 1932, No. 6950. [Class 38 (iii).] For electrically propelled vehicles a single brake pedal is provided, the first part of the movement of which operates a master controller for rheostatic braking, and the final movement of which applies the mechanical brake, means being provided for limiting the braking circuit while permitting free movement of the braking pedal. The master controller M first energizes coils SB1, SB2 to connect the motor armature 8 in a rheostatic braking circuit including the series field and resistance R0 .. R7. Only after this circuit is completed can a coil S1 be energized to close a contactor 1 and exclude resistance R0 .. R1. Further movement of the controller will then exclude resistance sections in succession. If a rapid movement of the controller is made through the rheostatic braking stages to apply the mechanical brake, an excessive rheostatic braking current is prevented by means of relays 3a, 5a. These relays are of the type described in Specification 175,815, [Class 38 (iii),' Electric motor control systems &c.], each having two coils a, band a<1>, b<1> respectively, which are energized by the completion of the braking circuit. When the contactor 2 closes the coil b is short-circuited, but the contacts 13a are maintained open by the coil a to prevent closure of the succeeding contactors until the braking current falls. The relay 5a acts similarly, to prevent closure of the contactors 5, 6, 7 if the braking current is excessive. Reference has been directed by the Comptroller to Specification 360,099.
