Title: Improvements in or relating to the production of dispersions of solid carbonaceous matter in oil
IPC: C10L1/32
Filed: 1936-11-27
Abstract: In the process for making dispersions of coal in oil described in the parent Specification according to which a paste of powdered coal and water is kneaded with about an equal amount of oil whereupon the ash and water are separated, the oil is subdivided into fractions of different boiling point and these are added separately.  Preferably a low boiling fraction is used in a first stage when the bulk of the ash is removed, and then the high boiling fraction or fractions are added.  Example, an aqueous paste of coal is kneaded with a distillate from an oil obtained by hydrogenating coal and boiling up to 250 DEG  C. at 8 mm. pressure. After separation of the water and ash, and washing with water, the distillation residue is added with further kneading to form of dispersion which can be readily pumped.

Filed: 1969-06-27
Abstract: 1,216,810. Steaming apparatus. DUPLAN CORP. 27 June, 1969, No. 32753/69. Heading B5B. [Also in Division D1] A multifilament thermoplastic yarn, e.g. of nylon or polyethylene terephthalate, having crimps, curls or loops and which possesses latent crimp is bulked by overfeeding the yarn, e.g. 10-120%, through a steam chamber and subsequently through a zone of unconfined steam directed outwardly from the chamber in the direction of yarn travel whereby the latent crimp is developed. The wound-up bulked yarn may be dyed and/or heat-set on the package. The steam chamber may be an upwardly directed tube having an open top and a substantially closed bottom through which the yarn passes. Steam enters at the bottom and is blown out at the top to form an unconfined zone round the yarn.

Abstract: 1287447 Gas turbine engines; bearings ROLLS-ROYCE Ltd 26 June 1970 [28 June 1969] 32799/69 Heading FIG A gas turbine engine comprises a compressor rotor and a turbine rotor drivingly connected together, one of the rotors being split into at least two sections each including at least one stage of blading, each of the rotor sections being supported in its own thrust bearing, the rotor sections being connected through means which transmits torque but substantially no axial load. The engine shown comprises an HP compressor 11, combustion equipment 12 and HP turbine 13, the turbine being connected to drive the compressor through shaft 23. The compressor comprises seven rotor blade stages 20 and is divided into an upstream section 25 comprising two rotor blade stages and a downstream section 24 comprising five rotor blade stages, the upstream section 25 comprising a shaft portion 27 which is supported in a thrust bearing 29, and the downstream section comprising a shaft portion 26 which is supported in a thrust bearing 28. The two shaft portions are inter-connected at 30 for example by means of a spline connection so as to allow torque to be transmitted from the shaft portion 26 to shaft portion 27 but no axial load. Thus the axial thrust on the shaft 23 due to the difference in gas loads on the compressor section 24 and turbine is not transmitted to the compressor section 25.

[Also in Group XL (c)] A transistor comprises a semiconductor body having a region (n) of one conductivity type separating zones (p) of the opposite conductivity type, at least two of the zones (1 and 2) having electrodes and each being separated by a distance less than the minority carrier diffusion length from a third zone (3), the distance between the two zones (1 and 2) being greater than this length. In Fig. 2, emitter e and collector c electrodes are connected to zones 1 and 2 of P-type material, and a potential is applied between electrodes b1 and b2 connected to N-type mass n. The third P-zone 3 has an electrode e1 but may be left at floating potential. Electrodes e and c are biased forward and reverse respectively relative to mass n. Zones 1-n-3 and 3-n-2 each operate as a transistor, and signals V1 applied to electrode e appear in amplified form at electrode c. To restrict the current between electrodes b1 and b2, a further disconnected zone of P-type material may be provided between zones 1 and 2 to reduce the cross-sectional area of the n-zone, or the n-zone may be made of high resistance N-type material. The signal may be applied to electrode b1 instead of e which is then earthed. The signal circuit may be gated by applying control potentials to electrode b2. Amplitude and frequency demodulator circuits, and frequency changing circuits are described.

A flash apparatus has a rotatable socket in which a flash cube can be inserted, and which itself can be coupled to a rotatable member in a camera. As shown, the flash apparatus 4 has a socket 23 into which fits the foot 26 of a flash cube 5, the socket being supported on a rotatable spindle 24. On spindle 24 is a pinion 25 meshing with a pinion 21 on a further spindle 16, which carries at its lower end a coupling disc 18 having a bent-down lug 19. The apparatus 4 has a flanged base 15 enabling it to slide into an attachment shoe 2 on a camera housing 1. Recessed in the shoe is another coupling disc 8, having a slot 9. When the apparatus 4 slides into the shoe, the two coupling discs 8, 18 are in contact, and locked together by the engagement of lug 19 in slot 9. Also, spindle 16 makes an electrical connection with a centre contact 3. Disc 8 is in driving engagement, via pinions 11, 13 and a sprocket 12, with the film-advancing mechanism 14. Thus after a flash exposure, the flash cube is rotated to the next position by the film advance. To enable the apparatus 4 to be used also with cameras having a conventional shoe attachment without the means for engagement with the film advance mechanism, a gear train 21, 25 is provided within the apparatus itself, which can be operated manually by a knob 27 whose rim projects externally. Figs. (not shown) 2, 3, 4 illustrate a modified method of attachment to the shoe.

This combination is normally held towards the right by a spring 24, so that the thread assembly which it carries lies under the frame 5 ready to be picked up. When the appliance 7 is pressed down into position, a hook 35 engages a bar 33 and a link 27 moves the slide 15 towards the left, to engage a further thread assembly, while, at the bottom of its movement, it disengages the hook 48 from the assembly already in position, so that slide 21 is drawn back to the left, by spring 22, to allow it to engage the following assembly, while the appliance 7 itself picks up the one previously placed in position. The lower, or applicator, plate of the thread assembly is retained by jaws 52 when the appliance 7 is pressed down and the thread carrier is transferred to it. This plate is subsequently pushed clear when the next assembly comes forward.
