Abstract: 621,997. Liquid fuel burners. WELLMAN SMITH OWEN ENGINEERING CORPORATION, Ltd., SMITH, C. H., and ASPLAND, R. C. D. March 3, 1947, No. 6057. [Class 75(i)] A fuel oil adaptor apparatus for use with a burner intended for gaseous and/or pulverised fuel comprises two spaced concentric tubes 18, 20, one of which is supplied with fuel oil, the other with air or steam, both tubes being carried by a block 12 secured to a block 11 mounted with clearance on a sleeve 7. The latter is threaded into the sighting hole of a burner of the kind described in Specification 576,438 or into a hole in a plate secured to the tubular gas jet member of this type of burner. The outer concentric tube 18 is screwed into a recess 19 in the inner face of the block 12 and the inner tube 20 extends into a recess 21 in the rear face of the block 12 and is secured by a gland nut 22 allowing for differential expansion of the tubes. An air or steam supply passage 24 extends through one side of the block 11 to a tubular dowel 25 which engages holes in the adjacent faces of the two blocks and is connected by a passage 26 in the block 12 to the recess 19. A similar line supplying oil fuel includes a tubular dowel 28 and connects a passage 27 in the block 11 to the recess 21. The two blocks are accurately aligned by a peg 13 on the block 11 engaging a hole in the block 12 and are held together by a single screw 15. Packing material is placed around a shoulder on each tubular dowel and between the blocks and the clearance of the block 11 on the sleeve 7 permits the two blocks to be drawn together and to take up such relative position that the joints around the dowels are effectively sealed. The front ends of the two concentric tubes 18, 20 are screwed into a nozzle block 31 which has a central passage 36 aligned with the inner tube and has a series of ducts 35 connecting the annular space between the tubes with a conical space between the outer end of the nozzle block and a cap 33 threaded thereon. The rear end of the cap 33 is of reduced diameter so that it will part, when unscrewed, from a nut 39 behind which shims 38 are inserted. Accordingly the shims 38, which provide adjustment of the conical space, are not disturbed when the cap 33 is removed for cleaning. Combustion air is supplied from the air inlet of the gas burner to which the adaptor is fitted. Gaseous or powdered fuel may be burnt at the same time as oil. The assembly comprising the block 11, the concentric tubes and the nozzle block 31 can be withdrawn to prevent carbonisation when the oil flow is shut down without disconnecting the oil and air or steam supply pipes.

Abstract: 1,020,786. Clocks. B.& R. RELAYS Ltd. Jan.23, 1964 [Feb.15, 1963], No. 6220/63. Heading G3T. [Also in Division H3] A circuit for producing an output pulse for a slave clock from each alternate input from a master clock comprises a bistable transistor circuit which is switched by pulses derived from the input pulses through a peaking transformer. The trailing edge of the input pulse cause a high voltage peak to occur in the secondary winding which through a gating circuit MR3, MR4 (Fig. 1, not shown), cause the bistable circuit TR2, TR3 to change its state. On each alternate pulse, TR2 becomes conducting and discharges a capacitor C1 to momentarily operate relay RLA. Contact A1 of this relay, when closed, renders transistor TR1 conductive to apply a pulse to the output line for the slave clocks. A diode MR5 clips the pulse produced at the leading edge of the input pulse, diode MR6 prevents damage if the supply connections are reversed and a PB1 is a test button.
