Title: A reliable switch position monitor for an RF switch in a communications satellite
Inventor: LLOYD DAVID W
IPC: H01H9/16
Filed: 2008-07-10
Abstract: Actuating coils L1-L4 for an RF multi-position switch are energised selectively by switches S1-S4. Microswitches S9-S12 with series capacitors C1-C4 are coupled across the actuating coils and close in response to the position of the RF switch, thereby providing an AC signal path which enables the switch position to be detected reliably by feeding an AC signal to a selected actuating coil through switches S5-S8. No additional wiring is needed between the RF switch and the monitor. Reliable switch position monitoring is achieved at a low cost and with little extra weight and circuit complexity. A switch array may replace the multi-position switch.

Inventor: CASTAGNER JEAN LUC LAURENT
IPC: G06F3/0346
Filed: 2009-06-02
Abstract: A display panel (eg TFT LCD) for determining the three dimensional position of a light reflecting or emitting object (400, 401, 410) in front of a display surface (100). An array of sensors (310) is disposed in the panel and provided with optical arrangements such as apertures in masks (321, 331) within the panel.

Title: Device for supplying fire-extinguishing foam to oil tanks
IPC: A62C3/06
Filed: 1932-04-09
Abstract: 401,005. Fire - extinguishing. MOELLER, B. A., Palos VerdÚs Estates, California, U.S.A. April 9, 1932, No. 10245. Convention date, April 10, 1931. [Class 47 (ii).] A device for supplying fire-extinguishing foam to oil tanks comprises a flexible, fireresistant, tube, which normally hangs down within the tank, but is adapted to be floated up to the surface of the oil by the buoyancy of the foam when the latter is admitted to the tube. As shown, the tube E, which is connected to a foam pipe D, comprises a portion E<2> which is permeable to foam, and an impervious portion E<1>. Part of the foam escapes from the portion E<2> and runs down the tube to the surface C of the oil, and the remainder is delivered on to the surface from the end H of the tube, which has been floated up to the surface by the buoyancy of the foam. In a modification, the whole of the tube is of impervious material. The open end of the tube may be flared and flattened, or surrounded by an open mesh cage. If the tube is too heavy to be raised by the buoyancy of the foam alone, it may be fitted with floats. In another modification, the upper part of the tube is impervious, and the lower part pervious. In this arrangement, the under surface of the portion which is buoyed up in use may be impervious. Specifications 331,800, 337,221, [both in Class 47 (ii), Fire-extinguishing &c.], 341,103, and 341,348 are referred to. The Specification as open to inspection under Sect. 91 states that the impervious portion of the tube may be of tightly woven asbestos fabric reinforced with wire, or may be a multijointed metallic tube, and the pervious portion should be of an open mesh asbestos cloth. It describes also an arrangement in which the tube normally is rolled up in a housing on the tank, and is unrolled automatically by the pressure of the foam when this is admitted, or is released into the tank by hand or on the melting of a fusible link. It further describes the arrangement of large-mesh tubes in a vertical position in the tank; the use of a tube formed entirely of flexible metal; and the use of a tube formed entirely of pervious material which may be collapsable or non-collapsable. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to transmitters for a.c. telegraphy
IPC: H04L27/12
Filed: 1956-04-04
Abstract: 818,180. Frequency and phase shift radio signalling; keying carrier frequencies. SIEMENS & HALSKE A.G. April 4, 1956 [April 4, 1955], No. 10332/56. Class 40 (5). [Also in Group XL (b)] Carrier telegraph signals are produced by modulating in amplitude, frequency or phase an oscillator whose operating voltage is derived wholly or in part by rectifying the applied telegraph signals. As shown, a common base transistor oscillator has applied to its collector and base positive operating and bias voltages respectively derived from rectifiers R1--R4 to which keying signals from terminals K1, K2 are applied, the base positive bias being obtained from the collector positive voltage developed across capacitor C2 by voltage divider resistors W2, W3, and the emitter being connected through D.C. stabilizing components W7, C9, W5 and C2 to a tapping or tuned circuit L2, C3. The inductor L2 is transformer coupled alternatively to a further inductor L3 or to a capacitor C6 by rectifiers R7-R12 selectively opened and blocked by + and - D.C. telegraph signals applied at K1, K2 so that the operative frequency of tuned circuit L2, C3 is varied accordingly. Frequency shift signals variable in amplitude by a potentiometer W8 serving also for impedance matching to an output filter are thus produced. Two diodes R5, R6 in parallel opposition may be connected in series with resistors W4, W4<SP>1</SP> across the tuned circuit L2, C3 to stabilize the oscillator output against variations in operating voltage, the resistor W4<SP>1</SP> having a negative temperature coefficient to compensate for temperature changes in the diodes R5, R6. In a modification, on-off A.C. signals are produced by applying + and - D.C. keying voltages to a balanced rectifier bridge at the output of the oscillator. Phase shift keying is also referred to.

Title: Improvements in the production of methyl ketones
IPC: C07C49/557
Filed: 1961-03-22
Abstract: Methyl ketones are made from terminal epoxide compounds of the formula <FORM:0905821/IV (b)/1> , wherein R is an alkyl, alkenyl, cycloalkyl, aryl or aralkyl radical which may bear substituents non-reactive with magnesium halides, by isomerisation in the liquid phase at 50 DEG C. to 250 DEG C. in the presence of a magnesium halide as catalyst.  Examples of suitable epoxide compounds are propylene oxide, 1,2-epoxybutane, 1,2-epoxybutene-3, 1,2-epoxydodecane, 1,2-epoxy pentane, 1,2-epoxy pentadecane, 1,2-divinyl-4-epoxyethylcyclohexane and its isomers, 1,2-epoxy-3-phenylpropane, orthonitrostyrene oxide, and ortho-methoxystyrene oxide.  The isomerisation may be carried out in an inert solvent or diluent such as toluene, xylene or an ether.  The preferred magnesium halides are the iodide and bromide, which are suitably used as their etherates. When the boiling point of the epoxide is low the reaction is preferably carried out under pressure. Small amounts of isomeric aldehydes may be formed together with the desired methyl ketones. Examples describe the preparation of methyl decyl ketone, methyl tridecyl ketone, acetone and also the methyl ketones from the isomerisation of the monoepoxides of 1,2,4-trivinylcyclohexanone. In Example 5, propylene oxide yields in addition to acetone, some propionaldehyde and high boiling condensation products.  The methyl ketones prepared by this reaction may be used as perfumes or for combating granary pests.
