Patent GB-736904-A (GB)
Title: Wax composition and process for producing wax
Inventor: JR WILLIAM TYNDALL KNOX
IPC: C10G73/02
Filed: 1953-05-01
Abstract: A wax is obtained by catalytically cracking a petroleum oil boiling in the range of about 650-1100 DEG  F., separating a fraction boiling in the range of about 700-1100 DEG  F. from the cracking products, removing aromatic compounds from this fraction and segregating wax from the aromatic-free fraction.  The dewaxed oil remaining may be employed as lubricating oil or as a cracking feedstock.  The removal of aromatics may be effected by adsorption (using an adsorbent such as silica gel, activated coke or clay) or by solvent extraction (using a solvent selective towards aromatics, for example liquid sulphur dioxide, phenol, furfural, nitrobenzene or liquid ammonia, alone or in conjunction with solvent modifiers).  The segregation of wax from the aromatic-free fraction may be effected by solvent dewaxing employing as dewaxing solvent, for example, propane or one or more aliphatic ketones having 3-6 carbon atoms in the molecule such as methyl-ethyl ketone, together with a minor proportion of aromatic hydrocarbons such as benzene or toluene if desired.  In an example, a petroleum gas oil boiling in the range of about 650-1100 DEG  F. is catalytically cracked, an oil boiling in the range of 700-1100 DEG  F. is separated from the cracking products and this oil is solvent-extracted using phenol containing 7 per cent of water as the solvent.  The raffinate is freed of solvent and dewaxed by adding sec.-butyl acetate, heating to about 120 DEG  F., cooling to 0 DEG F. and separating the wax which precipitates. Apparatus is described in which crude petroleum is fractionated to yield various fractions, including a fraction boiling in the range of about 650-1100 DEG  F., this latter fraction is catalytically cracked (details of the cracking catalyst and conditions of cracking being given) and the cracking products are fractionated.  The bottoms product from this latter fractionation is freed of catalyst and solvent extracted and the raffinate is then dewaxed.

Abstract: 591,124. Photographic materials. COLLINS, R. B., EDWARDS, H. D., PRATT, O. E., and ILFORD, Ltd. May 15, 1945, No. 12175. [Class 98 (ii)] A coloured layer is formed by applying to a layer of water-permeable colloid containing a surface-active compound an aqueous solution of a dye which has a different electrostatic charge from that of the surface active compound. The coloured. layer may be an antihalation or a filter layer ; an originally colourless layer may be converted, when required, to a coloured layer, without permanently colouring other layers of the element. A colloid layer containing an anion-active compound is treated with a basic dye and similarly an acid dye is used in conjunction with a kationactive compound. Suitable anion-active compounds are water soluble salts formed from alkali metals, ammonium, or amines such as triethanolamine and cyclohexylamine ; and, (a) long 'chain alkyl carboxylic acids such as oleic, ricinoleic, linoleic, stearic and palmitic acids ; (b) long-chain alkyl sulphonic acids ; (c) sulphated higher fatty alcohols such as lauryl and oleyl hydrogen sulphate ; (d) sulphated secondary alcohols containing at least eight carbon atoms in the chain ; (e) alkylated aromatic sulphonic acids, which include the benzene, naphthalene and hydroxy diphenyl derivatives ; (f) long-chain alkyl esters of sulphonated succenic acid. Basic dyes which may be used with these anion-active compounds include Auramine O, Rhodamine B, Rosaniline hydrochloride and Chrysaniline. Kationactive compounds which may be employed are the alkyl-, aryl- and aralkyl-substituted ammonium compounds and quaternary salts of heterocyclic nitrogen compounds such as dodecyl pyridinium sulphate, cetyl pyridinium bromide and octadecylamine, and materials sold under the Registered Trade Marks Lissolamine A, Sapamine MS and Fixanol C ; and the corresponding acid dyes include Tartrazine and Eosine. The colloid layer which is to be coloured may be composed of gelatin, casein, agar-agar, lowly esterified polyvinyl acetate, partially hydrolysed methyl methacrylate resin, cellulose ether or lowly esterified cellulose acetate.

Title: Improvements in optical apparatus for testing the human eye
IPC: A61B3/028
Filed: 1958-04-17
Abstract: 865,361. Sight testing instruments. BIESSELS, W. J. April 17, 1958 [June 12, 1957; Oct. 16, 1957], No. 12197/58. Class 97(1) A system for examining the spherical and astigmatic defects of the human eye comprises one or more test objects disposed at a preselected examination distance in front of the eye, and optical means adapted to produce simultaneously a plurality of images of said test object(s) in front of and behind the eye said images being of substantially equal size, shape, colour, and brightness conditions but differing in their distances from the eye which focuses these images in various planes in front of, on, or behind the retina. In the system shown in ,Fig. 1 a single distant object is used and objectives 141, 1411 form images thereof, but since the path of the rays passing through lens 1411 and being reflected by mirror 12 and half silvered mirror 13 is longer than that of the rays passing lens 141 the final images are not formed in the same plane. In the system shown in Fig. 3 the two objects 14L 14K are in different planes and therefore the final images L 1, K will also be in different planes. The same effect is obtained if the two objects are in the same plane and the lens 12, 121 have different focal lengths. In order to test for astigmatism each of the objects 14L, 14K of Fig. 3 are replaced by a pair of linear gratings the lines of which are mutually perpendicular. In the apparatus shown in Fig. 7 light from two objects Y 1 , Y 2  is reflected from two collimating mirrors D 1 , D 2  on to an inclined plane mirror S which in turn reflects the light out of the plane of the paper through two image forming lenses V 1 , V 2 . (A similar apparatus for only one object is also described). The lenses may be spherical or astigmatic and may be combined with at least one complementary lens of ordinary or birefringent glass.

Title: Battery charging equipment
IPC: H02J7/02
Filed: 1967-03-07
Abstract: 1,146,563. Battery charging systems. INTERNATIONAL STANDARD ELECTRIC CORP. 17 March, 1967 [18 March, 1966], No. 12672/67. Heading H2H. Self-service battery charging apparatus of the type in which the customer inserts one or more coins to determine the charging time, comprises a conventional fixed polarity charging unit I and a coin-operated control device 2 which includes a run-down clock 4 and means to detect the polarity of the connected battery 3 and to operate change-over switches accordingly so that the battery is correctly connected to the charger 1. The battery polarity is detected by the circuit comprising relays K2, K3, diodes 10, 11 and a current-limiting non- linear resistor 9, the relays K2, K3 respectively controlling contacts K21, K22, K23 and K31, K32, K33. Connection of the battery 3 to terminals 12, 13 causes actuation of the appropriate relay and connection of the battery to the charger terminals 14, 15 through a high resistance 8 which permits only negligible charging current to flow. Timer contacts KF are closed by insertion of the first coin and remain so until the expiry of the selected time period, which is determined by the momentary closure of contacts KM each time a coin is inserted. Initially the simultaneous closure of contacts KF, KM energizes a self-locking relay K1, so that the resistor 8 is shunted by two circuits comprising resistors 5, 6 and resistor 7, relay K1. This allows the flow of substantial charging current whose value is maintained relatively constant by making the resistor 5 non-linear. This charging current continues to flow until contacts KF open or until the battery is disconnected (should this occur before the expiry of the selected time), such disconnection de-energizing relay Kl whose selflocking contacts K11 open to restore the charging circuit to the stand-by condition (resistor 8 only). The polarity detector and switching part of the apparatus may be modified, e.g. by using two polarized relays or a single magnetic polarized relay having a neutral mid-position.
