Title: Improvements in oil fuel-burning apparatus for domestic and other heating uses
IPC: F23D11/44
Filed: 1948-08-24
Abstract: 670,324. Liquid-fuel burners. PARR, K. Aug. 24, 1948 [Aug. 26, 1947; Sept. 19, 1947; May 14, 1948]. Nos. 22328/48, 22329/48 and 22330/48. Class 75(i). Oil burning apparatus comprises a vaporizing tube, having an upright portion 27 Fig. 1 containing a filter 33 and horizontal and downbent portions 28 and 30, the latter carrying a burner jet (not shown) the portion 27 communicating with a valve casing 4, Fig. 2, containing a non-return valve 22 adapted to control oil pulsations, a blowback valve 18, and a sliding device 9 adapted to be withdrawn to lower the level of the oil in the part 27 in order to extinguish the burner or to be reciprocated to clear an obstructed jet. The vaporizing tube is connected by a pipe 24 to a bored plug 16 screwed into the valve casing 4 and providing a seating for the blow-back valve 18 which is controlled by a spring 19 and has an inlet passage 21 having a wall 21a providing at its upper end a seating for the non-return ball valve 22. Oil fuel is delivered by gravity through a pipe 2 to an inlet passage 5 in the casing 4 controlled by a needle valve 6 operated by a handwheel 13 on the member 9. The latter is provided with an inner longitudinal recess having flat sides engaging a correspondingly shaped member 8 at the end of the needle valve member, which has an intermediate portion 7 screw-threaded into the casing 4. On opening the needle valve 6 fuel passes into the valve chamber 15 and raises the ball 22 without closing the passage through the plug 16. Should a pulsation occur in the fuel in the vaporizing tube the ball valve 22 will close and prevent the pulsation from passing to the fuel supply system; and in the event of an excessive vapour pressure within the vaporizing tube the valve 18 will be forced from its seating against the spring 19. As the latter at once closes the valve 18 upon the resulting reduction of the pressure acting against it the return flow of fuel through said valve occurs without surging. To extinguish the burner the needle valve 6 is closed by turning the handwheel 13, and the member 9 is drawn quickly outwardly to cause a suction within the valve casing 4 to open the blow back valve 18 and allow the fuel to flow back from the vaporizing tube. On re-starting the burner the member 9 is pushed inwardly and the needle valve 6 re-opened. The filter 33 may be of stainless steel wire wool which may be wound around with a wire strand or have a wire fabric jacket to facilitate insertion into the tube 27. The horizontal portion 28 of the vaporizing tube carries a flame deflecting plate 29, and a starting tray 32 for containing a light fuel for the initial heating of the vaporizing tube and nozzle (not shown) is mounted above the entry end of the tube 27. Specifications 2111/00, [Class 75], 286,150, [Class 75(i)], and 502,862 are referred to.

Title: Improvements in or relating to data storage apparatus
Inventor: BRADLEY EDWARD MICHAEL
Filed: 1960-06-29
Abstract: 942,561. Circuits employing bi-stable magnetic elements. INTERNATIONAL COMPUTERS & TABULATORS Ltd. June 14, 1961 [June 29, 1960], No. 22762/60. Heading H3B. [Also in Divisions G4 and H1] The thin film magnetic element of a data storage matrix has perpendicular easy and hard axes of magnetization, the two stable states of remanence representing binary " 0 " and " 1," and means for producing during the reading phase a field aligned with the hard axis in one sense, and during the writing phase a field aligned with the hard axis in the opposite sense together with a field along the easy axis in a sense dependent upon the digit to be written. The field along the easy axis preferably begins first and ends last. The construction is similar to that described in Specification 852,178 except that the angle between the drive conductors 3, 6 (Fig. 1), and the magnetic axes may be up to 8 degrees in either sense, instead of between 3 and 8 degrees in one sense only in the Specification referred to above. Pairs of driving conductors, one for each current direction may be used, or the individual films or film areas may be encircled by a driving winding. The write in currents are not critical, but the field along the hard axis must be sufficient to saturate the film. Readout may be destructive, if the two fields along the hard axes are of the same strength, in which case they may conveniently be produced by equal pulses of opposite magnitude from a transformer, avoiding the use of rectifying elements normally required, or non- destructive if the readout pulse is not sufficient to saturate the film, in which case it must be accurately controlled. The readout amplifier is sensitive only to the first of the two pulses induced in the readout wire. A matrix is described, and the film may be continuous, with the conductors plated thereon, and the substrate may be conductive, and used as a return conduction for the pick-up wire. Matrix.-Fig. 2 shows a four by four matrix. Each row may be considered as a storage location for a word of binary digits. The computer 24 controls the digit selector 13 and hence the digit drive wires 6a-6d, the word selection network 12, which includes ferrite cores associated with the word drive conductors 3a-3d, and feeds clock pulses over the line 25. The required ferrite core is set and reset, inducing first a writing drive current and then a reading drive current in one of the word drive wires 3a-3d. The pick-up conductors 9a-9d each are connected to an amplifier 14 controlled by the clock pulses to respond only to the leading edge of the output signals in the pick-up conductors. Conductors 6a-6d are connected to the secondaries of transformers whose primaries are in a driving circuit gated by a suitably delayed strobing pulse to produce during the writing phase a pulse whose sign depends on the digit to be written. Specification 880,383 also is referred to. Reference has been directed by the Comptroller to Specifications 845,604 and 880,383.
