Title: Improvements in or relating to the manufacture of polymerisation products of ethylene
Filed: 1943-12-31
Abstract: Telomers are made by subjecting ethylene and a compound containing carbon hydrogen and oxygen only and free from olefinic unsaturation to an elevated temperature and pressure in the presence of an ethylene polymerization catalyst.  Formaldehyde or formaldehyde yielding substances are excluded.  Preferred compounds are acetals, e.g. ethylal and 1,3-dioxolane; alcohols, e.g. methanol and ethanol; ethers, e.g. diethyl ether, tetrahydrofurane and 1.4-dioxane; esters, e.g. diethyl malonate, ethyl aceto-acetate, sec-butyl acetate, methyl propionate, methyl methoxy acetate, methyl n-butyrate, ethyl orthoformate, dimethyl adipate, methyl acetate; ketones, e.g. acetone and cyclohexanone; acids and anhydrides, e.g. propionic acid and its anhydride. Suitable catalysts are benzoyl and diethyl peroxides and sodium persulphate, oxygen, hydrazine derivatives, e.g. hydrazine sulphate and hydrochloride and dibenzoyl hydrazine, hexachlorethane, tetraethyl lead, ultra-violet light in the presence of diacetyl, mercury, alkyl iodides and acetone.  Buffer substances, e.g. sodium tetraborates, alkali metal secondary phosphates and carbonates may be present.  The reacting substances are preferably carefully purified to remove inhibitors.  A second polymerizable compound, e.g. vinyl acetate, may be used.  The process may be carried out in the presence of an inert hydrocarbon solvent and may be made continuous.  The products are greases or waxes and may be hydrolysed to form detergents.  The waxes may be used for paper sizing, in enamels, for water-proofing, as lubricants and modifiers for lubricating oils. Specifications 471,590, 497,643, 562,092, 578,584, 581,899, 583,173, 583,178 and p  8070/40, as open to inspection under Sect. 91, are referred to.

Title: Improvements in and relating to methods of and apparatus for reproducing, recording or portraying information
IPC: G06K15/14
Filed: 1955-07-29
Abstract: 783,732. Copying-telegraphy. GENERAL ELECTRIC CO. July 29, 1955 [July 30, 1954], No. 22017/55. Class 40 (3). [Also in Groups XVI and XXXV] In an apparatus for reproducing information, a magnetic image is produced on an endless ferromagnetic member by an impressing member moving relatively thereto, a developer including minute magnetic particles is applied to the image carrier to adhere to it in the image areas, the pattern of particles is transferred on to a removable support such as a paper strip for permanently carrying the information, and the magnetic image is removed by an eraser head, the particles being applied to the ferromagnetic carrier while in the apparatus and excess particles being conveyed to a reservoir. An electromagnetic stylus 11 supported on a carriage 12 is energized from a conventional facsimile transceiver, and the carriage 12 is moved by a scanning assembly 13 axially along a drum 17 carrying a ferromagnetic member 10, which drum is rotated slowly clockwise. The carriage is moved by a chain 42 so as to follow an endless path defined by guide channels in plates 38, 40 so as to traverse the drum during part of its path. A magnetic image is thereby formed on the member 10 line by line. Magnetic particles in suspension in a liquid in a reservoir 19 are forced by a pump 21 through a control valve 27 to an axial distributer pipe 26 having a slot through which the liquid is forced upwardly against the member 10 so as to run down it to the point 30 and return to the reservoir, a bypass pipe to the reservoir also being provided. The liquid adheres to the member 10 where the magnetic image is, and to a greater degree the more intense the image. The liquid then evaporates and the now-visible particle image passes in contact with a paper web 32 coated on its outer surface with a temperature-sensitive adhesive and passed round a roller 34 incorporating a heater 35, so that the particles are embedded in the coating to form a permanent image. The magnetic image is removed by an eraser head 37. For continuous operation, three carriages 11 each with a stylus are mounted on the assembly 13 and the drum is longer. For making several copies, the head 37 and stylus are rendered inoperative. The member 10 may be of an alloy of 29 per cent cobalt, 21 per cent nickel and 50 per cent copper, and the drum 17 of low carbon content steel. The particles may be magnetite suspended in alcohol. The paper web may have a titanium dioxide undercoat and adhesive coating, or a translucent paper may be used. The pressure exerted by the roller 34 is 8-10 lb. per lineal inch, and the roller is coated with rubber or neoprene. The stylus comprises a core of 49 per cent nickel and 51 per cent iron, with a tip of iron or silicon steel of diameter 6- 10 mils., being surrounded by an insulating plastic sheath. 96 lines are printed per inch of drum circumference. Specifications 686,009 and 733,484 are referred to.

A lightweight liquid butane container is reinforced by a metal tube (12), Fig. 1 (not shown), extending between opposite sides of the container and being closed at one end by a plug (22) and having a combined filling and emptying valve (34) at the other end adjacent orifices (20) in the tube wall. The container is constructed of an inner translucent wall (2) of thin flexible plastic material surrounded by a translucent envelope (4) of reinforced fibre glass whereby the amount of charge may be observed. Re-vaporization is assisted by conduction of ambient heat along the tube (12) which is increased by inserting the closure plug at an intermediate position (28). In a modification the lower plug may also serve to house a ball valve and a plurality of containers are superimposed and connected together in series by means of unions (41), Fig. 2 (not shown) (only one of which is shown). Each union is screwed into the upper valve housing (242) of a container and into the lower valve housing (22 1 ) of the container above and has a stem (43) for unseating valves (34, 34 2 ).

IPC: C07D201/16
Filed: 1957-07-12
Abstract: <PICT:0853330/IV(a)/1> Monomeric carolactam is removed from its polymerisation product by heating the polymerisation product at a temperature sufficient to melt the polymer, and passing the distillate first through a condenser maintained above the melting point of the caprolactam, where a considerable proportion of the monomer condenses as a liquid, and subsequently through a condenser maintained at a temperature below the melting point of caprolactam, where any remaining caprolactam is condensed as a solid.  In the example, the mixture of monomer and polymer is melted at 250 DEG C. under reduced pressure in vessel 1, the monomer being distilled off to condenser 4 maintained at 100 DEG C., uncondensed monomer passing to condenser 8 maintained at 40 DEG C. where it solidifies. Condenser 11 is identical with condenser 4 and is used when the latter has collected sufficient liquid monomer.

Abstract: 613,925. Actuating machines. PEGARD, M. Aug. 30, 1945, No. 22331. Convention date, Feb. 10, 1942. [Class 83 (iii)] A single lever device for controlling the movements of two or more mechanical members, such as the slides of a boring machine, and for operating electric switches for indicating the position of the members, is such that movement of the lever in one plane actuates one of the members and one of the switches to indicate the position of the part whilst in another movement the lever and these parts are not operated but another member and switch are operated. The lever h for controlling the movements of the slides in a boring machine is pivotally connected at 11 to a thimble 9 which is secured to a grooved collar 12 sliding on a shaft 2. The lever is pivoted at 5 in a bracket secured to a cam-disc 1 keyed to the shaft 2. Vertical movement of the lever in the gate 8 moves the thimble and collar 12 and by means of the lever 14 slides a toothed gear 19 on the shaft 18 to engage a wheel 20 for driving the feed shaft 21 of the boring head of the machine. Horizontal movement of the lever through the gate rotates the shaft 2 and slides a gear 25 from a neutral position to engagement either with a toothed wheel 26 or a toothed wheel 28 for driving respectively the main work table transversely or the intermediate slide longitudinally. A cam surface 10 on the thimble 9 on vertical movement operates an electric switch 38 which may light a signal lamp showing the feed engaged. Similarly on horizontal movement of the lever projections on the cam disc 1 operate switches 33, 34 for indicating the members actuated.
