Abstract: 268,485. British Thomson-Houston Co., Ltd., Trencham, H., and Fetch, H. S. Jan. 29, 1926. Cut-out arrangements. - In order to improve the selective action of time-limit overload protective devices, the time-limit device which may be a fuse 18, Fig. 3, in series or parallel with the trip coil 17 of the circuit-breaker is energized by the usual current transformer 13 through a saturable transformer 15 so that the current to the fuse cannot exceed a predetermined maximum which corresponds to the minimum time-lag of the fuse. The saturable transformer is shown as a biassing transformer as described in Specifications 193,434, 216,254, and 246,995, and tappings 19 are provided to vary the overload setting. In the arrangement shown in Fig. 4, when the fuse 18 blows on the expiration of the time-limit, a contact-arm 21 is withdrawn by the springs 23 from engagement with the fixed contacts 22 where it short-circuits the trip coil 17 into engagement with contacts 24. In this position the trip coil is connected directly across the current transformer and the saturating transformer is cut out. A number of these timelimit devices, with different adjustments, may be arranged one in each of a number of circuits to give discriminating protection.

Abstract: 1,018,235. Delivering sheets. FERAG, FEHR & REIST A.G. Jan. 23, 1964, No. 3014/64. Heading B6H. An overlapping stream of newspapers 1, delivered from a printing press 2 by a conveyer belt 3, and fed down a shoot 4 to spaced endless belts 6, are separated into counted batches by blades 24. The latter are pivotally mounted on carriages 20 freely and individually movable along a guide-track 12. Each carriage in turn is retained in the position 20<SP>1</SP> by a slidable bolt 28 engaging a stop 32 on one side of the carriage. The free end of the blade 24<SP>1</SP> rests on a plate 51 hinged on a cross-shaft 38. A microswitch 39 engages the upper edges of the newspapers and impulses an electronic counter each time a newspaper passes therebelow. The carriages are released one at a time from said position 20<SP>1</SP> by means of a solenoid 31 under the control of said electronic counter. On being released the carriage rolls up to a resilient stop 22. The associated blade 24 is inserted between two adjacent newspapers, as the stream advances, until its free end passes between the belts 5. An endless belt 9 between the belts 5 has abutments 10 which engage the free ends of the blades 24 to move them with the stream. The blades eventually assume a vertical position and are locked in this position by projections 26 thereon engaging a guide-rail 27. The side edges of the stream are aligned by vibrating side plates 40 (not shown) and guided by stationary sideplates 41. The latter bow the newspapers transversely to stiffen them. After disengaging the abutments 10, the blades and their carriages are moved up to resilient stops 42 and 23 by the continuously advancing stream. Finally, they are forced past the stops 23 and 42 and fed forwardly at a faster rate by endless chains 44 and 46 having members 42 and 45 thereon. The members 45 engage the carriages to lift them clear of the stream and re-position them on the portion 11 of the track 12. The counted batch is rotated through 90 degrees by a delivery cross 53 and fed by endless belts to a packing machine.

Patent GB-450107-A (GB)
Title: Improvements in the separation of solid inorganic and/or organic constituents from oils containing the same
IPC: C10G1/04
Filed: 1935-01-30
Abstract: Hard asphalts and other solid materials such as those difficult to convert by destructive hydrogenation, are removed from oils or residues containing oil by treating under pressure with saturated hydrocarbons containing from 6 to about 10 carbon atoms at a temperature from about 170 DEG  C. to a little above the critical temperature, whereby the solid substances are precipitated and removed.  Raw materials specified are tars, destructive hydrogenation residues of coal, and mineral oils from which ash, unconverted coal, and hard asphalt are removed.  Saturated hydrocarbons specified are hexane, cyclohexane, methyl cyclo pentane, heptane, octane or mixtures consisting mainly of these. Example: a residue containing oil obtained by the destructive hydrogenation of coal, is mixed with benzine consisting mainly of heptane and hexane.  A heavy oil poor in hydrogen is added to selectively dissolve the resins and some asphalt.  The mixture is then heated in a pressure-tight vessel to 10 to 50 DEG  below the critical temperature, e.g. 270 DEG  C., whereby a pressure of 20--25 atmospheres is spontaneously produced.  Pressure may be increased by adding nitrogen, methane or hydrogen.  After standing, the supernatant layer of oil solution is drawn off and freed from the solvent.  The extraction may be effected in counter-current or in several stages at different pressures. Specifications 17140/15, 323,791, [both in Class 91], 365,046, and 409,278 are referred to.

Patent GB-754823-A (GB)
Title: Improvements in or relating to core binders
IPC: B22C1/22
Filed: 1953-02-05
Abstract: A core-sand composition comprises a particulate mixture of sand and, as a binder therefor, a powder comprising a particulate water-soluble cellulose ether or ester and a resinous component which is a rosin and/or one or more thermosetting synthetic resins.  The powder may consist of a mixture of particles of the cellulose derivative with particles of the resinous component and/or of composite particles in which the cellulose derivative and the resinous component are present together.  The rosin may be tall oil rosin or a rosin derivative such as a saponified or esterified rosin, e.g. sodium, potassium or calcium rosinate, ammonium rosinate or a hydroxyalkyl rosinate. Rosincontaining substances such as tall oil, tall oil distillation products or tall oil pitch may also be employed.  A plasticizer such as dibutyl or dioctyl phthalate, or a minor amount of a synthetic resin, such as polyvinyl acetate or a sulphamide resin, may be added, to prevent the rosin from causing the formation of fine dust during the grinding of the finished core binder.  Examples of thermo-setting synthetic resins which may be used are urea-formaldehyde, phenol - formaldehyde, melamine, polyvinyl, sulphamide and acrylic resins. Synthetic resins which evolve formaldehyde when setting are preferred.  Suitable cellulose ethers or esters include water-soluble methyl cellulose, ethyl cellulose, methyl ethyl cellulose, hydroxy-ethyl cellulose, methyl and ethyl hydroxy-ethyl cellulose, water-soluble salts of cellulose ether carboxylic acids, sodium salts of cellulose sulphuric acid esters, cyanoethyl cellulose and sulphoethyl cellulose.  There may be added to the cellulose ether or ester a surface-active agent such as a salt of a higher fatty acid with an organic or inorganic base, an alkyl aryl sulphonate, a fatty alcohol or other alkyl sulphate, a sulphosuccinate; a polyalkylene glycol, a polyalkylene glycol ether of an aliphatic alcohol such as lauryl or cetyl alcohol or of a phenol such as butyl- or octyl-phenol, or a condensation product of a polyalkylene oxide with tall oil fatty acids, oleic acid or lauric acid.  In an example 5 parts by weight of tall oil rosin partially saponified with soda to an acid number of 100 are melted, heated to about 120 DEG  C., and 0.5 part of a polyvinyl acetate melting at 100-110 DEG  C. is added; 4.5 parts of ethyl hydroxy-ethyl cellulose are moistened with 1.5 parts of 95 per cent ethyl alcohol, heated to 70 DEG  C. and mechanically mixed with the resinous component.  The fibrous product is allowed to cool and ground to a fine powder, which is homogenized in a drum mixer.  The 10 parts of core binder thus obtained are mixed with 30 parts of water at 50-70 DEG  C., and the resultant paste is allowed to swell for a few minutes, whereafter 5 to 8 litres of the core binder paste are mixed for 5-10 minutes in an edge-runner mill with 100 litres of sea sand having a moisture content of 2 per cent. Swedish Specification 112,609 is referred to.
