Abstract: 349,433. Blowpipe burners. ALLEXLIVERSIDGE, Ltd. and STEPHENSON, A., Victoria Station House, London. Nov. 26, 1929, No. 36267. [Class 75 (i).] The mixing chamber A of an oxyacetylene, oxyhydrogen or similar heating burner is provided with a member or plug B which has an axial hole B<1> for the supply of one of the gases and is formed with a substantially conical front end disposed a short distance behind a substantially conical shoulder on the mixing chamber so as to leave a substantially conical passage for the other gas, and the gas discharge passage or passages b in the plug are arranged to cause the first gas to pass across the conical passage so that the two gases become intimately mixed. Fig. 1 shows one construction of burner in which the surfaces of the front end of the plug and the shoulder on the mixing chamber are both conical. Fig. 3 shows another construction in which the front end of the plug is formed with steps on to which the holes b open. The holes may be arranged either radially or tangentially and the shoulder of the mixing chamber may also be stepped. Fig. 7 shows the front end of the plug B fitted with a screw-threaded plug B<X>, the threads being made badly fitting or having their tips removed so as to allow the passage of the gas. In another construction, shown in Fig. 16, to prevent flame blow-backs the plug B is formed with external helical ribs fitting tightly a plain cylindrical bore in the rear portion of the mixing chamber. Alternatively the plug may be formed with single or multiple screw threads fitting badly in threads in rear portion of the mixing chamber. The plugs may be provided with straight or spirally grooved extensions B<2> projecting into the bore of the mixing chamber and, in some cases, extending to the burner tip. A perforated collar may be arranged between the extension and the tip. Fig. 25 shows a burner construction in which a central pipe B<IX> is provided for supplying oxygen for metal cutting, or air, nitrogen, acetylene, hydrogen, or water according to the purpose for which the burner is being used.

Title: Improvements in or relating to pallet trucks
Inventor: CURRY JAMES BRUCE
IPC: B62B3/065
Filed: 1957-11-21
Abstract: 902,898. Pallet trucks. ABC COUPLER & ENGINEERING CO. Ltd. Nov. 5, 1958 [Nov. 21, 1957], No. 36330/57. Class 78 (3). A pallet truck is provided with two extensible load lifting fingers having supporting wheels at their outer ends mounted on radial arms, these arms being actuated when the lifting frame is raised vertically on the truck to lift a load, so as to raise the outer ends of the fingers and ensure that the latter are maintained horizontal. As shown, each finger consists of members 8, 9, Figs. 1, 2, slidable in guides 10 on the truck, and secured to these members is a frame 1 provided with wheels 2 supported on crank arms 3. These arms are actuated to raise the outer ends of the fingers by a piston-and-cylinder device 5 which is supplied with fluid-pressure by a pipe 7 connected to a coiled pipe 23 housed in the member 9 and connected to one of the two hydraulic jacks 16, Figs. 1, 4, for raising the frame 24 supporting the guides 10. These jacks are connected by pipes 20, 21 to a valve 19 controlled by an operator whereby both jacks and the device 5 are operated simultaneously to maintain the fingers horizontal. The fingers are projected outwardly of the guides by operating the control-valve so as to introduce fluid through a pipe 26, Fig. 3, to the space 35 in the member 8 formed between the outer end of this member and a piston 27 on a tubular member 28 fixed to the frame 24.

Title: Improvements in or relating to thermionic valve frequency changers
IPC: H03F1/28
Filed: 1938-12-13
Abstract: 522,710. Valve circuits for wireless reception; thermionic valves. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and BELL, D. A. Dec. 13, 1938, No. 36361. [Classes 39 (i) and 40 (v)] The signal-to-noise ratio in a frequency changing value is increased by reducing the mean current flowing to the output anode to a valve only just sufficient to carry the intermediate frequency output current component. Electrons from cathode 1 are focused into a beam by the negative electrode 2 and the positive electrode 3 having a slit 4, and the beam is intensity-modulated at the frequency of the local oscillator 9, 10 by applying a controlling voltage to the electrode 2 or to-an additional grid (not shown) external to the electrode 3. The beam is deflected between the " split " anode 7, 8 by the signal voltage applied to deflector plates 5, 6, the part 7 of the anode being connected to the intermediatefrequency output circuit 13. The deflection control may be electro-magnetic. A bias is applied to the deflector plates from a potentiometer 15, or the anode parts are slightly displaced, so that in the absence of a signal practically all the electron beam falls on the idle anode 8, whilst on receipt of a signal the current flowing to anode 7 is proportional to the product of the signal and local-oscillator voltages. More than one electron beam may be used, all the beams being modulated in intensity by the local oscillator and being deflected by the signal.

Title: Apparatus for contacting liquids
IPC: B01D11/04
Filed: 1964-09-04
Abstract: 1,044,200. Liquid-contact apparatus; continuous mixing apparatus. R.E. TREYBAL. Sept. 4, 1964 [Sept. 17, 1963], No. 36460/64. Headings B1C and B1F. Apparatus for contacting two incompletely miscible liquids of different densities comprises a vertical column of superposed decks a, b, c, d, e, each deck being divided by a partition 12 into a mixing compartment 10 and a settling compartment 11 and these two compartments communicating by a mixed liquid port 30, each settling compartment further communicating, by light liquid riser 22 and heavy liquid downcomer 16, with the mixing compartments of the decks above and below respectively, each mixing compartment having an agitator 60 and the column having a top inlet 73 and bottom outlet 79 for the heavy liquid and a bottom inlet 77 and top outlet 75 for the light liquid. The apparatus is used for heat transfer between liquids, for solvent extraction processes, for chemical reactions between liquids or for combinations of these processes. In use, heavy liquid flows downwards and light liquid upwards, and the two liquids are mixed in each compartment 10 and then passed into compartment 11 where they separate. Mixed liquid enters each compartment 11 through the port 30 and an adjoining tunnel 31, extending half way across compartment 11, and some of the settled liquids may then return to the mixing compartment 10 on the same deck through light and heavy liquid recycle ports 40, 41. The rotation of agitators 60 on their common shaft and an arrangement of baffles (Fig. 4, not shown), across the ports 40, 41 and the riser and downcomer openings into each compartment 10, effect this circulation. The ports 40, 41 and the riser and downcomer openings through each partition 12 are controlled by gates (e.g. see 43b), the respective gates on corresponding openings being each adjustably clamped to a common vertically movable shaft. These four shafts 45, 49, 53, 55 extend from the top of the column. Ports 30 could be similarly fitted. The whole column is normally filled by liquid, but the outlet 75 may emerge from a side wall to enable a pressurized blanket of gas to be maintained above the upper liquid level, in compartment 11a. By manipulation of the valve shafts 45, 49, 53, 55, one liquid may be made to accumulate in the apparatus, whereby the interface between the liquids in each compartment 11 (visible on gauge 117 for example) may be moved up or down, and "phase-inversion" of the mixtures in compartments 10 effected.

Title: Interchangeable objective lens
Inventor: NOACK ROLF
IPC: G03B9/70
Filed: 1968-08-02
Abstract: 1,208,513. Interchangeable objectives. PENTACON DRESDEN KAMERA-UND KINOWERKE VEB. Aug. 2, 1968, No. 37008/68. Heading G2A. An interchangeable lens for single lens reflex cameras has a built-in diaphragm and shutter, and means for closing a flash circuit. When the lens housing is attached to the camera, the diaphragm is opened to maximum aperture, and the exposure value of the aperture set on a scale. On depressing the camera release, the shutter being open for view-finding purposes, the diaphragm closes down to the pre-set value. The shutter blades 1 close, the focal plane shutter opens to a long time exposure, and the shutter blades 1 open again to effect the photographic exposure and fire the flash-bulb. Fig. 1 shows the shutter-controlling mechanism, and Fig. 2 the diaphragm-controlling mechanism. The shutter blades 1 (only one being shown) are opened and shut by a blade drive ring 4, which has a drive pin 5 entrained in a fork 6 of a drive lever 7. Thus rotation of the lever 7 about its spindle 9 drives the blade ring 4. Fig. 1 shows the shutter mechanism in the cocked position, a drive ring 13 being held tensioned, against the action of a spring 14, by means of a detent tab 21 thereon which is latched behind a spring-loaded detent lever 26. The movement of the diaphragm blades 46 is controlled by the setting ring 64, itself actuated by the setting lever 49. Initially, attaching the lens to the camera causes a diaphragm release member 33 to pivot clockwise. An arm 53 on member 33 engages against one end of lever 49, pivoting it anti-clockwise, and a fork 50 at the other end of lever 49, entraining a pin 51 on ring 64, rotates ring 64 anti-clockwise against a spring 47. This movement causes the diaphragm blades to open fully. The required exposure aperture is pre-set by a ring 66 reading against a scale 67, the ring 66 having a cam portion 65. On depressing the camera release, arm 53 is pivoted away from lever 49, so that lever 49 and ring 64 are drawn clockwise by spring 47, thus closing the diaphragm blades until a pin 52 on lever 49 abuts against the cam 65. This prevents the blades from closing any further. At the same time the lever 26 is pivoted out of engagement with tab 21, allowing the drive ring 13 to run down under the action of spring 14. A tab 15 on ring 13, previously engaging a pin 11 on lever 7, now releases it, so that lever 7 can be pivoted by a spring 8 to close the shutter blades 1. The focal plane shutter opens, and a dog 22 on ring 13 engages with an escapement mechanism, so that the running down of ring 13 is delayed until the focal plane shutter is completely open. A cam 16 on a lever 17 pivoted to ring 13 now strikes pin 11 on lever 7, causing it to open the shutter blades 1 to effect the photographic exposure. At the same time a tab 20 also carried by ring 13 closes a switch 35 to fire the flash 38.

Filed: 1938-12-21
Abstract: 509,127. Coiling dough. PETERS, H. H. C. Dec. 21, 1938, Nos. 37232 and 37233. Convention dates, Dec. 21, 1937, and June 11, 1938. [Class 87 (ii)] Sheets of dough on a conveyer 2 are coiled by two driven rollers 20, 3, one of which is movable under the influence of the growing coil 1, and a separating plate 16 is provided which is movable under the influence of the coil to shield one roller from contact with the dough to permit discharge of the coil. In Fig. 2, the dough sheet passes under a flattening roller 24 and contacts with the roller 3 which is carried on an arm 8, pivoted on a shaft 5 and carrying a counterweight 9. The dough sheet is coiled between the roller 3 and a polygonal roller 20 mounted in fixed bearings and the coil causes the roller 3 to lift about the pivot 5. Both rollers are driven by chain gearing 6, 22 from the shaft 5. The separator plate 16 is pivoted in a slot 14 in a lever 13, the other end of which has a pin-and-slot connection 11 with a projection 10 on the arm 8. As the roller 3 rises, the plate 16 is moved between the roller 3 and the coil, finally allowing the finished coil to pass out beneath the plate when it strikes a projection 16b and returns the plate to its initial position. In a modification, Fig. 6, the roller 3 is mounted in fixed bearings and the roller 20 is carried by an arm 37 pivoted about a shaft 35 from which the rollers are driven. The separator plate 48 is pivoted on an arm 45 which is fixed to a shaft 44 driven by a chain-wheel 41 fixed to the arm 37. The plate 48 shields the roller 20 and allows the dough coil to pass over the roller 3 while a projection 49 bears on the shaft 35 and causes the plate 48 to compress the coil.
