Patent GB-689170-A (GB)
Title: A process for the manufacture of refined sugar cane wax
IPC: C11B11/00
Filed: 1949-07-21
Abstract: Refined wax from cane sugar factory filter cake or press mud is obtained by extracting the dried cake by means of benzene, toluene, petroleum hydrocabons or other suitable solvent, evaporating the extract to small bulk, crystallizing the wax therefrom by cooling, separating the crude wax by filtration, and thereafter subjecting the product to distillation under a pressure of 0.5 to 10 mm. of mercury. The distillate consists of an almost colourless, odourless hard wax, leaving a residue of dark, very hard wax.  The crude wax solvent extract may be evaporated to dryness with omission of the crystallizing step.  The temperature of distillation may range from 150-400 DEG C.  Open steam or other vapour or permanent gas may be introduced into the distillation vessel, in which case the pressure of distillation may be from 2.0 to 50 mm.  The distillation causes inter-esterification between the waxy and any fatty materials in the crude sugar cane wax These fatty materials may, however, be removed before the distillation step, by extracting the evaporated crude wax solution with acetone or other suitable solvent, the resulting slurry being cooled to crystallize the wax. The wax finally obtained may be modified by incorporating with either the crude wax or the wax obtained after the treatment with acetone &c., a polyhydric alsohol, such as ethylene glycol, glycerol, sorbitol, sorbitan or isosorbide, mannitol, mannitan or isoacetone &c., a polyhydric alcohol, such as palmitic or stearic acid, in an amount depending on the free carboxyl or hydroxyl content of the waxy material.  The mixture may be subjected to distillation directly, or may be first heated, in the presence of a catalytic amount of sulphuric acid followed by neutralization with soda ash, calcium carbonate &c. and then distilled. Specification 1332/15, [Class 91], is referred to.

Title: Improvements in and relating to inclinometers, specially applicable for use in measuring the stability of ships
IPC: F41G5/22
Filed: 1925-07-29
Abstract: 255,239. Abell, T. B. July 29, 1925. Clinometers particularly for determining the stability of a ship by determinmg the inclination produced by transferring a known mass from one point on the ship to another, comprise a frame carrying a sensitivelysuspended heavy pendulum operating by motion-magnifying means a recording arm moving over a sheet also carried by the frame, whereby, when the frame moves with the ship &c. which in addition to receiving the inclination to be measured is subject to small variable, periodic oscillations, the mean angular position of the pendulum relatively to the frame can be measured. In order that the pendulum may quickly place itself in the direction of gravity, its natural period is made very small compared to the period of movement of its point of suspension. The heavy pendulum C, having a short period of the order of 0.25 seconds, is pivoted between brackets B on the frame A and carries a gear segment c<1> operating a pinion d<1> to which is secured an arm D carrying a pen P bearing on a record sheet on a clockwork-driven drum E. The pendulum is suspended by a knife-edge system comprising plane surfaces b<1> on the brackets B. carrying two pairs of bearing studs F<1>, F<2> and two surfaces c<2>, c<3> on the pendulum carrying corresponding knife edges G<1>, G<2>. The bearing surfaces of the studs F<1> lie in a plane at rightangles to that of the bearing surfaces of the studs F<2>, and these two planes intersect along the axis of suspension 0 of the pendulum. A frame consisting of two levers H rigidly connected by an arbor h<1> is pivoted between one of the brackets B and a bracket h<5> and carries at one end an arbor d<2> to which is secured the arm D and pinion d<1>, the arm being counterweighted by a mass d<3>. At the other end the levers H are joined by a cross-bar h<9> connected by a spring h<8> to a screw h<7> forming an adjustable stop by which the engagement of the pinion d' with the segment c<1> can be varied. When the pinion is moved out of engagement with the segment, the arm D can be held by a pivoted catch h<16>. The pen P. preferably consisting of a glass tube with a capillary opening, is mounted on a spindle p<2> in a bracket p<1> at the end of the arm D and is balanced by a weight p<4>. The arbors may be mounted in jewels to reduce the effect of friction, and to this end also the whole instrument may be agitated as by a light hammer of very short period, such as that used in an electric bell.

Title: A process for the production of organic carboxylic acids
Inventor: VOS JOHAN MARIE
IPC: C07C51/14
Filed: 1960-06-02
Abstract: In a process for the production of organic carboxylic acids by the reaction of mono-olefinically unsaturated compounds with carbon monoxide and water in the presence of an acid catalyst, di- and/or polyolefinically unsaturated compounds which may be present are removed from the mono-olefines prior to the reaction. The mono-olefines which may be obtained by the thermal vapour phase cracking of paraffin wax in the presence of steam, or by the cracking of solvent refined catalytically cracked heavy hydrocarbon oil are freed from di- and polyalkenes by, for example, fractional, azeotropic, and extractive distillations, extraction with selective solvents, such as aqueous solutions of cuprous chloride, polymerisation, and selective hydrogenation, for example, with catalysts containing copper, nickel or cobalt. Polymerisation, for example, with aqueous phosphoric acid on a carrier such as metallurgical coke; treatment with concentrated sulphuric acid; or selective hydrogenation using hydrogen in the presence of supported copper chromite are the preferred methods for the removal of the di- and poly ethylenically unsaturated compounds.  Acid catalysts mentioned for the acid preparation are phosphoric or sulphuric acids, hydrated boron trifluoride, or acid complexes thereof, sulphuric acid, and anhydrous hydrogen fluoride.  Specifications 743,597, 871,278, 873,738 and 883,142 are referred to.
