IPC: F24C3/10
Filed: 1955-11-22
Abstract: 802,976. Lighting burners. METALLWERKE GEB. SEPPELFRICKE. G.m.b.H. Nov. 22, 1955, No. 33397/55. Class 75(3) Ignition means for a gas stove or the like with one or more gas regulating taps 4, 4b arranged in a row, each one having a closed position in which it is secured against unintentional opening and being temporarily coupled to the movable iron core of a magneto device M for producing an opening of the tap, burner ignition sparks through the displacement of its core by a bar link 23 longitudinally displaceable behind the row of taps, is such that an initial movement of each of said taps from the security closed position to a released position brings about a coupling between the tap and the bar 23. The valve 6 of a central ignition jet head 8 is opened by the core linkage 10, 12 to allow gas to flow to the head 8. The oven burner 4a is ignited from the head 8 by a flash back tube 4e, the tap 4b regulating the oven having a spring detent, which becomes effective to resist rotation of the tap beyond, e.g. a 45 degree turn so as to delay further movement for about 10 sees. at the end of which period the gas from safety valve 4d reaches the top of the tube 4e and is ignited to light the ignition flame for the oven burner 4a on further movement of the tap by production of the spark across the gap 9 of the ignition jet head 8. As shown, each tap handle 4, 4b is provided with a spring biased plunger 26 which is adapted on coaxial movement of the handle 4, 4b against spring bias to release the handle from its security position, effected by a radial pin locating in an axial notch in the tap housing) to engage the plunger 26 in a guide slot 24, in the bar 23 whereupon rotation of the tap handle, the bar is moved longitudinally to actuate a linkage comprising a bellcrank lever 22, rod 21 and lever 10, 12, pivoted at 11, and spring 13, to move the core of the magneto device M to produce a spark across the gap 9 and at the same time, the movement of the lever 10 by engaging the lever 10a opens the auxiliary valve 6 to allow gas to flow to the ignition jet head 8, the movement of the core opens a contact in the primary circuit of the magneto device to produce the spark. When the tap handle moves up to its large-flame position, e.g. at a 90 degree turn, on release, it moves under its opening bias, axially to release the plunger from the slot 24 whereupon the bar 23 returns under the action of a spring 25 to its unoperated position and the tap may be freely adusted by continued rotation between the large-flame position and economy flame position. Specification 802,977 is referred to.

Title: Flexible wire and cable shielding
Inventor: MURPHY JOSEPH WILLIAM
IPC: H01B9/02
Filed: 1965-08-04
Abstract: 1,081,207. Screened conductors. NORTHROP CORPORATION. Aug. 4, 1965, No. 33423/65. Heading H1A. Flexible multi-wire RF cable 11 is shielded against electro-magnetic interference at from low to high frequencies by two-layer shielding 12, 14. The outer layer 14 is of a magnetic material with relatively low permeability and good conductivity, such as pure iron, and the inner layer 12 of one with relatively high permeability, such as permalloy. The outer layer provides good shielding against highfrequency interference and attenuates lowfrequency signals so that the high-permeability layer, which has the low saturation point usual with high-permeability shields, is not -overwhelmed by large amplitude low-frequency signals. If the shielded cable carries signals which are to be prevented from interfering with external apparatus the low-permeability layer may be on the inside, and if the highpermeability layer is placed between two lowpermeability ones shielding is effective both from the inside out and from the outside in. If a cylinder of low-permeability material is formed about one of high permeability, then flattened to form a sandwich and rolled so that it curls until its edges are adjacent (Fig. 4, not shown) the resulting cylindrical shield of this type may be installed around an existing wire.

Title: Improvements in or relating to apparatus for manufacture of chlorine dioxide hydrateand the like
IPC: C01B11/02
Filed: 1954-11-18
Abstract: In the production of chlorine dioxide hydrate by passing sulphur dioxide into an acidified solution of a chlorate, e.g. sodium chlorate acidified with sulphuric acid, and absorbing the chlorine dioxide produced in water, the sulphur dioxide and chlorine dioxide are carried by an inert gas, e.g. air, which is circulated between the chlorine dioxide generation and absorption stages, the absorption and generation stages being connected by a water pump connected at its lower end to a separation chamber from which water is returned to the pump and gas to the circuit. Liquids other than water, e.g. oil, may also be used in the pump. In a modification the water pump and connected separation chamber act as generator.  A vent may be provided in the circuit for the removal of gas or the addition of inert gas.  Superatmospheric pressure may be maintained if desired. The proportion of sulphur dioxide to air may be 1 to 4.  The temperature in the generator may be 30-50 DEG C.  The concentration of chlorine dioxide produced may be 20-30 per cent.  The generator may be equipped with rupture plates to prevent damage due to to an explosion.  The absorber is maintained at a temperature of ca-1 to +1 DEG C. by the addition of ice or by means of a cooling jacket or cooling coils through which water or brine is circulated.  The separation chamber may be surrounded by a jacket for controlling the temperature.  The supply of sulphur dioxide may be cut off in the event of trouble in the compressor system by means of a solenoid valve connected with a manometer.  Solution may be continuously or periodically removed from the generator for crystallizing out sulphate formed therein and for fortifying with further chlorate. The apparatus can also be used for the reaction of chlorine with an aqueous solution of a chlorite to produce chlorine dioxide, and also for the recovery of a solvent evaporated from a material by passing a heated stream of inert gas through the material.  Specification 742,898 is referred to.
Patent GB-886799-A (GB)
Title: Improvements in timing pulse generators for digital computers and the like
IPC: H03K3/30
Filed: 1959-10-02
Abstract: 886,799. Circuits employing bi-stable magnetic elements. METCALFE, H. F. Nov. 2, 1960 [Oct. 2, 1959], No. 33449/59. Class 40 (9). [Also in Group XL (c)] A pulse oscillator comprises a pair of transistors connected in separate current paths, at least two saturable magnetic core elements connected in series in each path, cross-coupling circuits between each path and the transistor of the other path, and means to couple the magnetic core element together in a ring such that no two elements in the same current path are directly coupled together, the arrangement being such that the transistors alternately assume high and low conductivity states as a saturation state progresses round the ring. The Figure shows two transistors A, B having their base and collector electrodes cross-coupled and each having two square loop core inductors M1 M3 and M2, M4 in their respective collector path. Each core is coupled to one of the cores in the opposite current path to form a ring, as shown by the arrows, each coupling including a diode and resistor circuit such as is shown between cores M1 and M2 so that coupling is effective in one direction only round the ring. Assume transistor A is conducting and core M1 is switching between the states. The switching continues until the core saturates whereupon the collector electrode of transistor A becomes more negative and switches on transistor B at the same time the coupling between M1 and M2 has caused M2 to be reset, causing the current through transistor B and core M2 to provide a voltage at the base of transistor A to switch it off. When core M2 saturates the voltage at the collector of transistor B becomes more negative, switching transistor A again and so the cycle continues around the ring of cores. In an alternative embodiment (Fig. 2, not shown) diodes are connected between the collector electrode of the transistors and the first core and the cross-coupling resistors are connected to the end of the diodes next to the inductors. This ensures complete switching of the cores and prevents them being driven through subsidiary hysteresis paths.

Abstract: 782,086. Photo-electric testing arrangements. .UNITED STATES STEEL CORPORATION. Nov. 25, 1955, No. 33908/55. Class 40 (3). Photo-electric apparatus for detecting pinholes in sheets having substantially parallel sides includes means for guiding the sheets accurately through the detector and for preventing light spilling round the edges of the sheets and giving an erroneous indication. In one embodiment the sheets are brought to the inspection position by endless band conveyer 2 and carried away by a second conveyer 4. Above the sheet path and extending across its full width is light source 18 in a suitable slotted cover. Below the sheet path and extending right across opposite the light source slot is a photo - sensitive detector 20 comprising a plurality of photo-cells and associated circuitry. Spaced guides 24R, 24L are arranged to guide the sheets through the detector. Each guide consists of a substantially horizontal part 26 extending from the entrance end to beyond the inspection position and an upwardly extending part 28 preferably leaning slightly outwards (Fig. 3, not shown). The exit end of guide has a cover part 34 spaced above the part 26 a distance slightly greater than the sheet thickness and the parts 26 and 34 have slots 36 and 38 almost as far as part 28 at the inspection point. A nut-and-screw type mounting controlled at 50 enables the two guides to be moved in opposite directions so as to be placed with the parts 28 separated by a distance only slightly wider than the sheet. When so placed the guides hold the sheets down at the inspection point and prevent light leaking round their edges. Shields 40 are attached to, and extend outwardly from, each guide; they prevent light from source 18 reaching detector 20 at points outside the guides.
