Title: Improvements in or relating to the preparation of pigmented compositions
IPC: C09B67/20
Filed: 1948-07-02
Abstract: A colour base, of a type comprising a finely-divided pigment uniformly dispersed in a viscous liquid vehicle of considerable body, is prepared by a method comprising: (i) heating the pigment and vehicle to 80-90 DEG  C.; (ii) mixing them together; (iii) circulating heating fluid through the roll of a mill of a special type, to heat the roll to 70-90 DEG  C.; (iv) placing the hot mixture in the mill hopper; and (v) subjecting the mixture to the action of the mill while the roll is at 70-90 DEG  C. and the grinding bar is thrust towards the roll with a force of from 190-240 pounds per square inch length of bite.  The special mill is one which has a cylindrical power-driven roll, a grinding bar operating against the roll, a scraper for removing processed material, a hopper for feeding in material, and a vane extending from the grinding bar a short distance around the roll to form a wedge-shaped pocket leading to the bite, the grinding bar having two elongated operative surfaces facing the roll and separated by a narrow shallow recess leading back to the hopper.  The grinding bar may carry a coating of a viscous liquid, e.g. blown castor oil, and the mill may have a roll of 26 inches axial length and a 10 degree vane, being, for example, a 26 inch Keenok mill.  The colour base pigment may comprise titanium oxide, and the vehicle may be blown castor oil, "Sextol" (Registered Trade Mark) phthalate, or a mixture of blown castor oil and tricresyl phosphate or dibutyl phthalate.

Title: Electromagnetic vibrators, telephones or the like
IPC: H04R11/00
Filed: 1922-07-01
Abstract: 209,118. Signal Ges. July 1, 1922. Addition to 184,154. Electromagnets.-In a telephone receiver, electromagnetic vibrator or magnetomicrophonic relay, employing a field magnet a in which both the iron and copper losses are reduced and made substantially equal, as described in the parent Specification, the armature b is made of such a thickness that the flux through it is slightly below saturation. As an example, with iron capable of carrying 10000 lines per sq. cm., the cross-section of the armature would be slightly lass than half that of the magnet. In order to permit an increased thickness of armature, the polar region of the magnet is reduced as shown. With such a shape of magnet, in order to obtain a substantial equality of the iron and copper losses the base is made somewhat longer than a limb, so that the space between the limbs, when completely filled with windings, will accommodate, the same quantity of copper as did the cubic space described in the parent Specification. The outer portions of the windings may be massed around the upper portions of the limbs so as to form a substantially rectangular structure.

A method of making a porous bearing member comprises compacting and sintering metal powder to form a porous body which is then forged to reduce the porosity and increase the strength and ductility of portions intended for securing the bearing in position. A thrust bearing is made from a porous sintered metal body 10 having an increased thickness at the ends 12 by forging to form a flat member with ends 121 of greatly reduced porosity. The member is then drilled at the ends to form holes 16 for securing bolts and at the centre to form an opening 18 to receive a reduced end of a shaft. The powder mixture may comprise 1-3 per cent graphite, 1-10 per cent of a nickeltitanium alloy and the balance iron, the nickeltitanium alloy preferably comprising 40-90 per cent nickel and 10-60 per cent titanium. The compacting pressure is between 20,000 and 120,000 pounds per square inch and the sintering temperature between 1900‹ and 2300‹ F. Other metal powder mixtures may be used and the mixture at the attachment portions may differ from that at the bearing portion.

Title: A process of treating mixtures containing free sulphuric acid and acid alkyl esters
IPC: C07C303/44
Filed: 1935-06-27
Abstract: The mixture of sulphuric acid and acid sulphuric esters derived from aliphatic alcohols is separated into two layers by the addition of a restricted quantity of water or an aqueous medium.  The free sulphuric acid is thereby recovered in fairly concentrated condition. Water containing a little alcohol or ether may be used as the aqueous medium and also an aqueous salt solution when the alkyl radicle of the acid esters contain less than ten carbon atoms.  In an example, a mixture obtained by sulphonating commercial primary hexadecyl alcohol with sulphuric acid is treated with water and alcohol, an acid of 56 per cent concentration being obtained.  After separation of the free sulphuric acid, further addition of water again produces two layers, the lower comprising an alkylsulphuric ester and the upper a mixture of polymers, neutral esters and uncoverted products. Specifications 446,026 and 459,080 are referred to.

Title: Ice bin level control mechanisms
IPC: F25C1/14
Filed: 1960-05-26
Abstract: 889,163. Ice-making. YORK SHIPLEY Ltd. (York Division Borg Warner Corporation). May 26, 1960, No. 18678/60. Class 29 An ice-making machine is switched off, when the ice receiving bin is full, by an ice-detecting arrangement involving an oscillating crank member which is trapped by the rising ice. As shown, the ice level detector is provided in the ice-making machine of Specification 889,081. A lever 81, 82 is pivoted on a bracket 78 of a rotatable part of the machine so that once each revolution thereof arm 81 is swept past cranked lever 71, 69, 70, 68, pivoted in brackets 66 on bin wall 61. The co-action of roller 72 with arm 81 causes plate 73 to make a swinging movement against the action of tension spring 74 to detect the presence of ice. Tension spring 80 is sufficiently strong to overcome the tension in spring 74 and allow this to happen. However when plate 73 is trapped by the accumulating ice flakes, roller 72 presents a fixed abutment to arm 81 and the lever is accordingly pivoted against the action of spring 80 to bring the path of adjustable arm 83 into line with switch actuating member 85. The switch opens the circuits of the machine compressor, fans, the driving motor and water recirculating pump and closes the timer circuit of a timer switch. The timer runs for a period of two hours during which the machine cannot be restarted.

Title: Improvements in or relating to processes for the preparation of carbon base materials and nuclear reactors including such materials
IPC: C04B35/52
Filed: 1958-06-12
Abstract: A carbon body, suitable for use in nuclear reactors as a moderator, or in the construction of reflectors or heat carriers, is prepared by forming carbon which contains deuterium but no hydrogen into shaped pieces, either by mixing the carbon with a deuterated heavy aromatic hydrocarbon and compressing the mixture, or by compressing the carbon and then impregnating the shaped pieces with the deuterated heavy hydrocarbon.  The pieces are then submitted to a homogenising treatment, which carbonises the hydrocarbon, to give a homogeneous carbon-deuterium product with a small content, i.e. 05-5% by weight, of firmly bound deuterium. The homogenisation may be effected by exposing to high energy, i.e. above 500 KeV, radiation, for example a , b , g  rays, fast electrons, protons, or neutrons, preferably at 100 DEG C.-300 DEG C., for example, by placing the pieces inside a nuclear reactor. Alternatively a purely thermal treatment may be employed, normally by heating to below 1000 DEG C.  The deuterium containing carbon may be obtained by carbonising deuterated heavy hydrocarbon material, as claimed in Specification 798,029, or by contacting carbon containing hydrogen with a deuterium-containing gas as claimed in Specification 823,198.  The deuterated heavy aromatic hydrocarbon material may be prepared by deuterating heavy aromatic hydrocarbons, i.e. hydrocarbons with a vapour pressure at least 20% below the operating pressure at homogenisation temperature. Suitable hydrocarbons include polycyclic aromatic hydrocarbons, for example, anthracene, phenanthrene, acenaphthene, diphenyl, fluorene, pyrene, benzanthrene, chrysene, and their homologues, and mixtures containing them, for example tar-oil fractions and aromatic extracts of mineral oil fractions.  Preferably the material has a melting point of at least 50 DEG C.  The deuteration may be effected by the method of Specification 798,030. Specification 851,548 also is referred to.
