Title: Improvements in or relating to the production of high quality lubricating oils
IPC: C10G21/12
Filed: 1942-11-13
Abstract: 566,413. Purifying and de-waxing mineral oils. AKTIEBOLAGET SEPARATOR-NOBEL. Nov. 13, 1942, No. 16088. Convention date, Nov. 26, 1941. [Class 91] In the production of high quality lubricating oils from lubricating oil fractions by the addition of a selective solvent thereto, cooling to de-waxing temperature, and then cooling the de-waxed oil solution to a lower temperature at which the paraffinic lubricating oil hydrocarbons are precipitated and separated in solid or semi-solid form, the process is effected in the presence of an aromatic or naphthenic fraction by returning a part of the extract solution containing the aromatics or naphthenics to the initial lubricating oil fraction. The wax separated in the first stage of the process may be de-oiled by washing with the solvent, the washing liquors being used as diluent for the initial material. After equilibrium is reached, an amount of extract solution is continuously withdrawn corresponding to the amount fed to the fresh oil. The solvent used in the dewaxing stage, the wash oil solution obtained in the de-waxing stage, and the extract solution obtained in the second stage are respectively preferably added stepwise at dropping temperature to the initial material. The wash oil solution may be added with the extract solution to the initial material. The de-waxing may also be effected at dropping temperatures. Only apart of the de-waxed oil may be subjected to the second stage of the process. The de-waxed paraffinic fraction forms a highquality lubricating oil and the withdrawn de-waxed aromatic or naphthenic fraction may be used as burning oil &c. after the solvent has been removed in each case. Usual selective solvents such as methylene chloride', dichlorethane, acetone, butanone and methyl propyl ketone or mixtures thereof may be used in the process.

Title: Improvements in or relating to the purification of resinous rubber transformation products
IPC: C08C19/10
Filed: 1941-12-13
Abstract: Resinous rubber transformation products obtained by heating rubber with phenols in presence of an isomerizing agent as described in Specifications 498,311, 521,007, 539,641, 541,898 and 541,899 are separated from the reaction mixture by heating with an aliphatic hydrocarbon or a petroleum product such as white spirit kerosine, spindle oil, &c. which dissolves the resinous product. Water containing alkali sufficient to neutralize the isomerizing agent is added.  After cooling and standing, the mixture separates with an upper layer containing the resinous product and a lower layer containing the impurities.  The upper layer may be wahsed with phenol as described in Specification 541,898 to separate further impurities and the resinous product recovered by distillating off the solvent. The distillation may be continued by addition of fresh solvent so as to remove phenol and the product further treated with steam.

Title: Improvements relating to combination locks
Inventor: TOOVEY WILLIAM
IPC: E05B17/18
Filed: 1964-04-17
Abstract: 1,120,833. Combination I o c k s . SEAL SAFE CO. Ltd. 19 July, 1965 [17 April, 1964; 25 Aug., 1964], Nos. 16113/64 and 34834/64. Heading E2A. A combination lock comprises a slidable plate 16 for location in a position where it obstructs a keyhole to be safeguarded and having a projection 17 thereon, a series of coaxial rotatable wheels 13, 14, each having one or more notches 13b or 14b in its periphery and the wheels being rotatable to positions wherein the, or one of the, notches of each lies opposite the projection on the said plate, means for indexing the rotation of said wheels so that various angular positions of the notches can be determined and means for displacing said plate when the projection and the notches are in mutual register. The lock shown has a body part 11 adapted to be fixed to a door over its keyhole to prevent access to the keyhole and the body part 11 has a boss 12 extending outwardly and axially thereof on which is rotatably mounted the inner index wheel 13; rotatably mounted on the wheel 13 is the outer index wheel 14. Each wheel has an index plate 13a, 14a, disposed within the body part and the plates contain the notches 13b, 14b in the peripheries thereof. The outer index wheel is axially located on the inner wheel between a shoulder 13c and the outer periphery of the inner wheel and the index plate 13a and both wheels are axially positioned by the engagement of a radially inwardly directed flange 11a on the body part with a channel in the periphery of the outer index wheel which is between the index plate 14a and the flange 14c formed integrally with the wheel. Guided in the slot 12a in the base of the boss is the slidable plate 16 which is retained in place in the slot by a base plate 21 secured to the rear base of the body part. The plate 16 is formed with the keyhole slot 18 and the plate is normally biased by a spring 23 so that the keyhole slot 18 is out of alignment with a keyhole slot 21a in the base plate 21 and a keyhole slot 15 in the boss. The slots 15 and 21 a are normally in alignment with the keyhole in the door and when the plate 16 is moved so that its slot 18 is in alignment with the slots 15 and 21a, a key can be inserted into the keyhole in the door. Movement of the plate 16 is normally prevented by the projection 17 on the plate which only allows sliding of the plate when the notches in the index wheels are in alignment with it. The plate 16 is moved by the tip of the key engaging the surface of a ramp 19a, secured to the plate. The index plates are indexed by spring loaded detent members which engage shallow recesses 13d, 14d around the periphery of each plate. In a modification more than one notch for the projection 17 can be provided in each index plate. In a further modification instead of the key being used to move the plate 16, a push button is provided located centrally of the boss 12 and the keyholes 15, 18 and 21A are offset; this arrangement allows the combination lock to be used if the door keyhole is near the edge of the door.
