Title: Improvements in or relating to a method of and apparatus for making controlled additions of water to gases
Inventor: SHEPPARD MALCOLM FREDERICK
IPC: C01B32/50
Filed: 1960-03-23
Abstract: 923,223. Controlling the water content of gases. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. March 23, 1961 [March 23, 1960], No. 10380/60. Drawings to Specification. Class 55 (2). A controlled amount of water is added to a gas by passing the gas through an aqueous solution undergoing electrolysis so as to add hydrogen and oxygen to the gas in the ratio of two volumes of hydrogen to one volume of oxygen, the gas containing hydrogen and oxygen being then thoroughly dried and passed over a heated platinum catalyst to recombine the hydrogen and oxygen to form water. The gas is bubbled so that it passes over the electrodes in the cell in which the electrolysis is being carried out. In an example, carbon dioxide is passed through dilute sulphuric acid undergoing electrolysis and containing hydrogen and oxygen, is dried first over magnesium perchlorate and then over phosphorous pentoxide before being brought into a spiral of platinum wire heated by an electric current to red heat. The water content of the carbon dioxide is controlled by varying the current to the electrolytic cell containing the dilute sulphuric acid.

Title: Improvements in or relating to oxygen jet cutting machines
IPC: B23K37/02
Filed: 1943-06-28
Abstract: 565,261. Dividing by fusion. HANCOCK, L. J., and CUMBER, W. F. June 28, 1943, No. 10451. [Class 83 (iv)] In an oxygen-jetmachine for cutting a plate or the like at an angle other than a right angle to the surface, the burner is mounted on . a horizontal arm or pair of arms attached to the machine by a horizontal pivot so that the burner may float up and down, a running wheel being connected to the burner holder adjacent to the nozzle and resting on the surface to support the nozzle in spaced relation thereto. The nozzle may thus be maintained at a constant height above the plate whether this is flat or undulating, thereby ensuring alignment of the bevelled cut. The machine may be of the portable or fixed type for straight or curved line cutting. An angularly adjustable burner 9 is carried by a holder 5 mounted on a slide bar 4 to which are fixed the outer ends of a pair of arms 6, 7 attached to the casing 1 by transverse horizontal pivots 8, the extended part of the other end of the arm 6 being provided with a counterweight 12. The casing is mounted on wheels 2 driven by a motor and to the bar, burner, or holder is secured a carrier 11 for a running wheel 10 which is arranged adjacent the nozzle and rests on the work so as to rise and fall with any undulations on the surface of the plate and thus move the burner holder about the pivots 8 so as to keep the nozzle at a constant height above the surface. The machine may travel on track rails 3 or directly on the work. The burner holder may carry two or three burners, e.g. in the latter case for cutting respectively the top and bottom edge bevels and a vertical face between the bevels. In another form, two independently floating burner holders with separate .running wheels may be carried by the machine for cutting two edges of a plate simultaneously.

Title: Improvements in or relating to liquid fuel sprayers
IPC: F23D11/38
Filed: 1920-04-15
Abstract: 159,775. White & Co., Ltd., J. S., and Forster, A. April 15, 1920. Nozzles for producing whirling sprays. - A spray burner comprises a body A, cap E, and annular plate H, which together form an annular chamber J to which oil is supplied through channels D in the head A<1> of the body, and which is connected by passages H<3> in the plate arranged tangential to a whirling chamber H<2>. For regulating the oil supply, a valve B which has a conical head B<1> is provided, and an enlargement B<3> immediately outside the orifice G serves to spread the oil spray. The cap E may be recessed as at E<2> to take the plate H, which is interchangeable and may have one or more fuel passages according to requirements, the depth of such recess being at least equal to the depth of the fuel passages H<3> so as to render the burner inoperative in the event of the plate being incorrectly placed in position. Or, in a modification, the head A<1> of the body may be recessed to take the plate H instead of the recess in the cap. The invention is stated to be an improvement on the burner described in Specification 4247/09, [Class 75 (i), Burners &c.], in that the resistance caused by the change in direction of flow of the fuel in entering the tangential passages is avoided by the provision of the annular chamber in which the change of direction of flow takes place gradually.

Title: Tire curing press
IPC: B29D30/06
Filed: 1954-04-09
Abstract: 755,992. Tyre-moulding presses. NATIONAL RUBBER MACHINERY CO. April 9, 1954 [May 12. 1953], No. 10563/54. Class 87(2) The bead ring 33, Fig. 3, is stripped from the tyre bead B by an upward movement of the bead ring from the moulding position shown, the ring being pulled upwardly into a recess 50 in the upper mould section 16. This upward movement is possible only'when pins 49 on the ring register with holes 51 in the upper wall of the recess. In the moulding position shown the pins do not register, but they are brought into registration by turning the ring about a vertical axis. The ring is turned by a fluid-pressure cylinder 52, Fig. 4, acting through ro'd 54. arm 55, ring 56 and tube 48 to which the bead ring is secured. The ring is pulled up into the recess by fluid-pressure cylinders 45 acting through rods 46 and crossbar 47 which is secured to tube 48. As shown in Fig. 5, the tyre may be initially freed from the mould section 16 by separation of the bead ring from the section, the ring being thereafter stripped from the tyre; alternatively the ring may be stripped as the press is opening. The ring has a lateral flange 33a which engages the side of the tyre bead, and is raised and lowered by admission of fluid pressure to either side of a piston 37. The lower mould section (not shown) may be fitted with a similar retractible bead ring. The press shown is of the integral curing diaphragm type and is described in Specification 5027/54.

Title: Signaling systems such as public address systems or the like
IPC: H04R27/00
Filed: 1937-04-14
Abstract: 493,846. Distributing music &c. GUIDED RADIO CORPORATION. April 14, 1937, No. 10636. Convention date, May 28, 1936. [Class 40 (iv)] In a system for distributing announcements &c. on ships, the signal currents are fed to the loudspeakers over two independent networks, preferably constituted by the neutral wires of the normal and emergency power wiring circuits with earth return, to which the signal source and loudspeakers are coupled through transformers, the object being to minimize failures due to undesired grounds and short-circuits and interruptions of the circuits. In Fig. 1, the two networks comprise neutral wires 7-9 and 16-18 branching respectively from the main neutral wires 6, 15, which are connected together through a switch 20 and an impedance 21 acting as a choke as regards the signal currents. The signal currents are applied to the networks through condensers 27, 28 from the output transformers 24, 25 of an amplifier 23, the secondaries being grounded at one end to the hull of the ship. Each loudspeaker 34 is fed through transformers 29, 30, the primaries being connected at one end through condensers 32, 33 to a wire of each network and at the other end to ground. The signal currents may be fed to the networks in opposition with respect to ground, the primaries of the transformers 29, 30 being in opposition. This arrangement has the advantage of reducing noise effects. Fig. 3 shows an arrangement for automatically short-circuiting the relevant output transformer 124, 125 in the event of a break in one of the feeders near the amplifier. The feeders are shunted by relays 128, 129 in series with a condenser 127, so that the appropriate relay operates due to the building up of potential, locks over a second winding and short-circuits the corresponding transformer. Fig. 5 shows a system for distributing modulated carrier signals, the loudspeakers 221 being fed through rectifiers 220, and at some stations through tuned circuits 219, so that those stations receive signals only when the appropriate carrier frequencies are transmitted. The Specification as open to inspection under Sect. 91 describes also modified systems in which the loudspeakers are coupled to the networks through condensers. This subjectmatter does not appear in the Specification as accepted.

Title: Photographic between-the-lens shutter with device for intermediate viewing
Inventor: TILLIG HELMUT
IPC: G03B9/08
Filed: 1964-03-13
Abstract: 1,034,254. Camera shutters. PENTACON DRESDEN., KAMERA-UND KINOWERKE VEB. March 13, 1964, No.10681/64. Heading G2A. A camera shutter can be opened for intermediate viewing by a lever which is securable against a return spring by a catch, the catch being releasable to allow the return of the lever, so closing the shutter again, either by (a) moving the lever itself directly, or (b) by means of the shutter release member. In the form shown, the shutter is set by a slider 1, movable along a bar 34 from left (rest position of Fig. 1, not shown) to right ("set" position of Fig. 2), against the driving spring 7. It is latched in this position by the end of a spring-loaded catch lever 5 engaging behind a nose 6 on the slider 1. When the shutter release trigger 26 is operated, this engages catch lever 5 and tilts it out of engagement with nose 6, allowing slider 1 to be pulled back by driving spring 7. The slider operates the shutter blades through a transmission lever 3, which turns on a pivot pin 32. As the slider 1 moves from right to left, a cam part 37 strikes a pin 33 on lever 3, so turning the latter clockwise. Then a nose 2 on the slider strikes against a second pin 4 on the lever, so turning it anticlockwise. The lever 3 has a forked end which embraces a pin 9 on the shutter blade operating ring 8, so that the two movements of lever 3, first in one direction and then in the other, causes the blade ring 8 to execute two similar movements, so opening and then closing the shutter blades. When the shutter is open, a pin 20 on the blade ring closes a pair of contacts 21, 22, which, through a connection 24, acutates a flash. After the shutter is set, the blades can be opened for intermediate viewing by a further ring having an operating lever 13, which is turned anticlockwise from the position of Fig. 1 (not shown) to that of Fig. 2. A lug 12 on this ring engages against a lug 10 on blade ring 8, so that this is also turned anticlockwise to open the shutter. The lugs are latched in this "shutter open" position by a spring-loaded catch lever 17 latching behind an inclined part 16 of lug 12. In this position a pin 25 on ring lever 13 runs up a sloping surface 40 of spring contact 23 and lifts it away from connection 24, so that the flash is not operated. The blades are closed again by releasing the catch lever 17 from the inclined surface 16, so that ring lever 13 returns under the action of spring 19. This release can be effected either by turning lever 13 slightly clockwise, or simply by the normal pressing of release trigger 26, which action itself unlatches lever 17.
