Abstract: 1498657 Liquefaction of coal; coking blends SOUTH AFRICAN COAL OIL & GAS CORP Ltd 22 May 1975 [24 May 1974] 22329/75 Heading C5E Carbonaceous material having a ring and ball softening point above 30 C. is produced from a solid carbonaceous fossil fuel material by a deoxygenation process in which the fuel is heated in contact with a liquid solvent having hydrogen carrier properties and hydrogen and the solvent and other volatiles are distilled off to leave the material which comprises both the soluble and insoluble components; the material is mixed with a larger amount of non-coking or poorly coking coal to produce a blend which can be coked to metallurgical coke. Suitable solvents are hydroaromatic liquids boiling between 200 C. and 450 C., creosote fractions, anthracene oil, coke oven tar fractions and partially hydrogenated aromatic extracts from lubricating oil refining. The treatment can be carried out at 350-500 C. and a hydrogen pressure of 30-250 bar. In the example brown coal is slurried in tetralin and heated with hydrogen in an autoclave; the product is distilled under partial vacuum to a cut point of 420 C. at 760 mmHg to yield about 50% by weight, based on the coal, of a residue.
Patent GB-440123-A (GB)
Title: Improvements in air-tight envelopes comprising ceramic materials
IPC: C04B37/04
Filed: 1934-07-31
Abstract: In airtight envelopes such as those of luminous electric discharge devices in which ceramic material is sealed hermetically to glass, the ceramic material is free from silica and consists of a compound of an alkaline earth with the oxide of titanium or zirconium.  The cracking of the glass due to the absorption of silica is thus avoided.  Examples are, 1 or 2 parts of MgO or BeO with 1 part of TiO2 or ZrO2.  The compounds when sintered at 1400 to 1500 DEG  C. are non-porous to air and will join to metals.  Other substances may be added to reduce the sintering temperature.  The electric leads may pass through a plate formed of the ceramic material to replace the usual foot tube, and an enamel of soft glass can be used to seal the joint.  The major part of the envelope may be formed of the ceramic material and the remainder of glass.  Metals may be sprayed or sintered on the surface of the ceramic material.

Abstract: 1,183,025. Dispensing fluids. H. TATSUNO. 10 May, 1968, No. 22381/68. Heading A4T. In a method and apparatus for controlling and automatic recording of dispensing from a plurality of fluid supply units, a cord comprising an individually perforated metal plate covered with opaque non-metallic material is inserted in a detector 16 between oscillators and H.F. detectors to emit a signal corresponding to a distinct number which actuates a switch 18 energising the pump 17 of a petrol or oil dispenser 19 and also feeds into a memory and stand-by circuit 25. On dispensing at 20, a flowmeter 22 pulses a computer 23 which signals to a circuit 24 which multiplies the quantity and unit price and feeds a signal to the memory circuit 25 from which a combined signal from 16 and 24 is fed to a scanner 26 receiving signals of unit price, type of fluid, date and purchase slip number respectively from units 27-30. Insertion of the card and manual control at 33 sends a signal to the scanner of the price of other articles purchased at the station. From the scanner signals are sent to a receipt printer 31 and a tape puncher 32. Concomitant signals for use of another dispenser 19a are delayed and stored in the stand-by circuit in memory 25.

[Also in Group XIX] Communication between low-temperature data processing units is effected by means of modulated light beams. As described a lowtemperature data processing unit 1 employing cryogenic devices is located within a first container 2 cooled by liquid helium, the container 2 being located within a second container 3 cooled by liquid nitrogen, communication between the unit 1 and other data processors (not shown) in adjacent containers, being by modulated beams of light 4, 5. The beams are passed from an external source (not shown) through cooled optical filters 6 in the containers 2, 3, the beams being deflected if necessary by mirrors 7 and modulated by means of thermo-optic modulators 8 (Fig. 2, not shown) which may be as described in Specification 926,796. The modulators 8 are coupled to and controlled by the data processor 1 and may be in the same container as the data processor or one associated therewith. The data processor 1 may be coupled by leads 9 to additional external components through capacitative leads such as those described in Specification 901,218 or inductively or by D.C. couplings.

[Also in Division F2] A rolling-diaphragm gas spring combined with a tube-within-a-tube type hydraulic piston-cylinder damper is made self-levelling by the provision of a vent port 55 in the outer wall of the damper's outer tube, this vent being covered and uncovered by the rolling diaphragm 68 as the piston of the damper reciprocates. Fig. 1 shows the collapsed state of the assembly. In use gas is supplied to the inlet 74 and the assembly assumes a position in which the relative position of port 55 and diaphragm 68 is as shown in Fig. 3. The vent communicates with the air-filled part 38 of the outer tube, there being a liquid-filled part 40 separated from the gas by a tubular diaphragm 32. In this and other respects-apart from the self-levelling means-the assembly is identical with that shown in Fig. 1 of Specification 1,207,800. The Specification states that the diaphragm 32 serves both to prevent aeration of the damper liquid and to compensate for expansion thereof. The rear end suspension means of a vehicle may include two of the above-described units combined with the necessary source of gas pressure.

Abstract: 1,098,946. Making sheet material. DUNLOP SEMTEX Ltd. May 6, 1965 [May 30, 1964], No. 22487/64. Heading B5A. A sheet 15 is formed by preheating thermoplastic particulate material 2 between heated steel belts 3 and 4 and passing the self-supporting sheet 7 thus formed between an endless tensioned heated steel belt 8 and a steamheated roller 9 in order to compress it to its final thickness. The belts 3 and 4 may converge (as shown) and are heated by platens 5 themselves heated by, e.g. electricity, gas burners or steam. If a terrazo effect is required upon one surface of the sheet, the belt which contacts that surface is maintained at a lower temperature than the other belt. Alternative pressing and heating means may act intermittently and may comprise press platens.

Abstract: 446,651. Barometers. GODY, H., Amboise, Indre-et-Loire, France. Aug. 2, 1934, No. 22531. Void [Abridged as open to inspection under Sect. 91 of the Acts, Feb. 9, 1935]. [Class 106 (ii)] The indicating mechanism is provided with additional means for indicating the direction in which the barometer needle is about to move. A toothed sector 12 having very fine teeth is secured to the axle 11 carrying the usual toothed sector 15 of the barometer. The sector 12 meshes with a tooth formed rigidly with a spindle 2 carrying a double point indicator 1. A small spiral spring 8 is fixed to the axle 2 and to a stud 10. The spring 8 is so arranged that when the finger or tooth 7 is in its position of rest its edge is in the line joining the axle 2, 11. On movement of the pointer clockwise to indicate a rise, the sector 12 turns counterclockwise and the end 1<11> of the indicator 1 is moved below the shield 20. In doing this the spring 8 is tensioned. As soon as a fall follows the spring causes the tooth again to mesh with the sector and the spindle 2 is turned the opposite way, the end I<1> moving below the shield to indicate a fall. An adaptation to a barometer having a chain is described.
