Title: Method and apparatus for the utilisation of naphtha or similar material as fuel in internal combustion engines
IPC: F02M1/00
Filed: 1932-10-24
Abstract: Fluid naphtha, heavy mazout, petroleum, &c. for use as fuel in internal-combustion engines with spark ignition is heated in bulk, at atmospheric pressure but out of contact with air, in a boiler heated by the exhaust gases or otherwise and cold air is induced to impinge forcibly and laterally on to a jet of the vapour produced to provide a stable cool homogeneous mist in which the air is in the correct proportion for combustion.  A constant level chamber E, Fig. 1, supplies fuel to a boiler A, kept about <PICT:0398357/III/1> <PICT:0398357/III/2> <PICT:0398357/III/3> half full thereof. Disposed in the boiler A, Fig. 7, is a tubular heating element through the tubes of which exhaust gases flow, a few of the tubes being located above the surface of the liquid to superheat the vapour.  The tubes are thin-walled and have short lengths of stouter tubes welded to their ends to improve their juncture with end boxes S, one box having a removable or other cover secured to a detachable end plate T of the boiler.  The other box is secured to an outlet pipe connected to the exhaust discharge pipe by an obliquely cut split ring clamped on the outlet pipe by a union nut screwed on the end of the discharge pipe.  The tubular boiler may be replaced by an externally heated boiler, Fig. 10, the exhaust gases passing through channels formed by contacting angular ribs welded to the boiler and to one another.  The boiler may be vertical instead of horizontal and be wider at its upper end to facilitate escape of vapour. Atmospheric pressure is maintained by a condenser D, for excess vapour, through which cooling water flows.  Vapour passes to the condenser through a pipe Q<1> and a Y-shaped pipe S<1> keeps open communication with the atmosphere

Abstract: 1,240,767. Recording tracks of particles. GENERAL ELECTRIC CO. 12 June, 1969 [28 June, 1968], No. 29919/69. Heading G6P. In a particle track registration process, the damage tracks in the irradiated material are exposed to ultraviolet light, in the presence of oxygen, prior to immersion in an etchant. A rapid selective etching along the damage tracks is effected and a more uniform cylindrical track is produced. The track forming particles may be derived from self-fissioning isotopes such as Californium-252, isotopes which limit alpha particles (radium-226), materials which fission and emit fission fragments when irradiated with neutrons (uranium 235); and materials, such as boron-10, which emit alpha particles when irradiated with neutrons.

Title: Improvements in or relating to clutches
IPC: F16D11/06
Filed: 1946-10-08
Abstract: 626,497. Clutches. LEADERFLUSH, Ltd., and BROUGH, R. A. Oct. 8, 1946, No. 29949. [Class 80 (ii)] A one-revolution clutch comprises a ratchet wheel 1 secured to a driving shaft 2, a driven drum 3 rotatably mounted on the shaft 2, and a bell-crank lever 6 pivotally mounted at 5 within the drum 3. One arm of the lever 6 extends through an aperture 10 in the drum and in the clutch disengaged position abuts against a stop 14 preventing engagement of a detent 7 formed on the other arm of the lever, with the ratchet teeth 8. A pin 12 on the drum 3, engaging a notch in a pivoted lever 13, prevents backward rotation of the drum. On removal of the stop 14, the detent 7 is forced into engagement with the ratchet wheel by the spring 11, thereby clutching the drum and wheel together. Before completion of the revolution the stop 14 is replaced so that it may engage the arm 9 of the lever 6 thereby disengaging the clutch. Specification 604,406, [Group XXIII], is referred to.
Patent GB-652605-A (GB)
Title: Improvements in or relating to flame failure control circuits using thermionic valves
IPC: F23N5/08
Filed: 1946-10-08
Abstract: 652,605. Liquid fuel burner control apparatus. COMBUSTION CONTROL CORPORATION. Oct. 8, 1946, No. 30025. Convention date, Oct. 9, 1945. [Class 75(i)] [Also in Groups XL(b) and XL(c)]. The Figure shows a control circuit for cutting off the fuel supply to a heating system when the flame has been inadvertently extinguished or when the water in the boiler has fallen below a predetermined level. When the flame is present the light from it renders photocell P conducting, thus shorting capacitor Cl and rendering valve T conducting during alternate half cycles of the A.C. supply across AB. Relay M is thus operated and A.C. is supplied via contact h to the fuel supply motor 1. When the flame is extinguished the photocell P no longer acts as a short across capacitor C1, thus during the half cycles of the A.C. supply across AB when point c is positive with respect to e the valve draws grid current and charges capacitor C1 via resistor R1. Similarly, if the water in boiler 3 falls below the level of the probe terminal 4 the A.C. supply across transformer winding L4 and 'consequently across the photocell P is removed thus allowing capacitor C1 to charge. After a delay dependent on the time constant of R1, C1 valve T is cut-off thus de-energizing the relay M and breaking the supply to the fuel supply motor. In a modification, Fig. 2 (not shown), a beam tetrode valve is used, the capacitor and photocell being connected in series across two tappings on the A.C. supply with their mid point returned to the control' grid of the valve via a resistor. Specification 583,851, [Group XL], is referred to.

Patent GB-303896-A (GB)
Abstract: 303,896. Air Reduction Co., Inc., (Assignees of Anderson, J. L.). Jan. 13, 1928, [Convention date]. Uniting by fusion.-In welding the abutting edges of metal sheets or the circumferential or spiral seams of pipes &c. by an oxyacetylene or like burner having a series of preheating and welding flames in which the work and burner are relatively movable in a single direction lengthwise of the seam at uniform speed, the welding part of the flame acts on a a surface which continually slopes downward towards the congealed weld, so that the fused edges of the work are caused to flow rearwardly. The burner 3 and sheets 2 to be welded are arranged in an inclined position, the welding jets of the burner impinging on the steeply sloping breast 4 of the region of fusion and the fused metal flowing downward and building up at 5 up to or beyond the surface of the sheets. Burners may be arranged on both sides of the joint so as to form a joint 5 with a double bevel as shown in Fig. 5. In welding circumferential joints of circular or angular tubes the preheating jets may be arranged over the top of the circle or over the forward slope thereof and the welding jets on the downward slope, the work being rotated to perform the weld. The metal at the end of the weld may be replaced by an additional operation or the end may be cut off, but in circumferential welding the work may overrun a complete rotation to smooth out any irregularity. The burner may have jets all of the same composition, or preheating jets of lower intensity. A longitudinally slitted burner may be used or a series of burners. Lateral compression may also be used, and, if desired, the seam may be reinforced by metal melted from a rod.

Abstract: 1309628 Stencilling machines SHINKO ELECTRIC CO Ltd and KOBE STEEL Ltd 29 June 1971 [29 June 1970 29 July 1970 21 Oct 1970] 30423/71 Heading B6C A method of marking a sheet, e.g. a hot rolled iron sheet, by means of a stencil comprises the steps of punching holes in the stencil corresponding to the required marking, feeding the stencil to a marking station along a first path, first path, feeding a sheet to be marked to the marking station along a second path perpendicular to the stencil path, and directing jets of marking material on the upper surface of the stencil for producing the required marks. The apparatus comprises endless conveyer bands 5, 5<SP>1</SP> on to which two stencils M1, M2 punched at stations 18, 19 are deposited by devices 16 described later, the bands 5, 5<SP>1</SP> conveying the stencils first to a position beneath sprayers 14, 15 and then after a marking operation to devices 17 similar to the devices 16 to remove the stencils from the bands 5, 5<SP>1</SP>. A second pair of conveyer bands 1,1<SP>1</SP> co-operate with the bands 5, 5<SP>1</SP> to grip the side edges of the stencils, and angle-shaped brackets 11, 12 prevent sagging of the bands. A roller conveyer 13 feeds a sheet K to be marked to the marking station in a direction perpendicular to the stencil path. The devices 16, 17 comprise roller conveyers which are displaceable vertically to positions where the devices 16 feed the stencils on to the bands 5, 5<SP>1</SP> and the devices 17 remove the sheets from the bands. The spacing L<SP>1</SP>, Fig. 3, between the punching stations, may differ from the spacing L, Fig. 1, between the jets, in which case the two parts 16a1, 16a2 and 16a3, 16a4 of the device are raised at different times so that the stencils are deposited on the bands 5, 5<SP>1</SP> with the required spacing L. The apparatus may be arranged so that two or more markings can be made on each sheet, the stencils being changed for each marking. Each punching apparatus 18, 19 is set to produce holes corresponding to the required markings by electric signals generated by a manually-actuated device such as typewriter or computor console. Stencil plates may be formed by bonding a metal foil sheet, e.g. of aluminium, on to a cardboard sheet, so that during the marking operation, the foil part faces the hot sheet.

Title: Polymerisation of olefins
Inventor: BOHLBRO HANS
IPC: B01J27/06
Filed: 1951-12-31
Abstract: Products of gasoline boiling range are obtained by polymerizing normally gaseous olefins in the vapour phase at 0-200 DEG , preferably 20-30 DEG  C., in the presence of boron fluoride chemisorbed on a binary or ternary gel which is itself active as a catalyst for cracking hydrocarbon oils.  Such gels include silica-alumina, magnesia, zirconia or titania, and silica-alumina-magnesia.  The major component of the gel is preferably acidic.  Thus, 60-90 per cent may be silica.  A silica sol may be formed by acidifying water-glass solution, this being allowed to set to a gel, impregnated with a salt of the second metal, e.g. aluminium nitrate, precipitated with ammonia, washed, and heated to activate.  Alternatively, the wet silica gel is mixed with a slurry of magnesia, dried, and activated.  Particles of 2-10 mm. may be used and boron fluoride adsorbed equivalent, for example, to 5-40 per cent by weight.  The feed gas such as cracked refinery gas is passed through a bed of the catalyst at atmospheric or higher pressure, e.g. up to 10 atmos.  Make-up BF3 may be added, e.g. in the feed, or a guard bed used to adsorb volatilized BF3, the direction of flow being later reversed.  In an example, a C4 feed is passed at 133 vols/vol. catalyst/hour over a commercial silica-alumina pre-dried at 200 DEG C. for 3 days and on which 20 per cent BF3 is adsorbed, the temperature being 20 DEG  C. initially and rising to 100 DEG  C.
