Abstract: In the cultivation of mushrooms from an underlying bed containing mushroom spores, novel compositions and processes are provided for a casing layer which is placed overthe compost layer containing spawning mycelium. A hydrophilic, thermosetting prepolymer resin is mixed in with a casing substrate, preferably Canadian peat, other optional additives and sufficient amount of water to form a slurry, and the mixture is allowed to cure to a spongy block. The cured material is then pulverized and deposited as a casing layer over the compost layer. Because of the high water retention qualities of this material, watering the mushroom beds is reduced by a factor of three or more, thereby reducing operation and production costs, as also the incidence and severity of disease and displeasing blemishes.

Abstract: A gas switching device for use with a gas supply system in which two gases, for example, oxygen and air are supplied to a medical unit comprises a manifold 106 to which are attached two identical valve assemblies 108, 110. The manifold has a first inlet 1 and outlet 5 for the passage therethrough of the oxygen and a second inlet 2 and outlet 6 for the air. Eeach valve assembly 108, 110 includes a spool valve 122 movable from a first to a second position under the influence of the pressure of its associated gas. At least one valve assembly 110 has an inlet 18' communicating with a passageway 15 in the manifold which, in turn, communicates with the inlet 1 for the oxygen and an outlet 22 communicating with a further passageway 16 in the manifold which in turn communicates with the outlet 6 in the manifold for the air. Should the air pressure drop below a predetermined value then spool valve 122 will move to its second position thereby permitting the passage of oxygen from inlet 18' to the outlet 22 in the valve assembly 110 so that oxygen exits from both outlet 5 and outlet 6.

Abstract: An improved thick film stannic oxide sensor SN is disclosed whereby the sensitivity of the sensor to CO is enhanced by the addition of a rare earth oxide (e. g., lanthanum oxide unlike ThO 2  in prior art) to the sensor composition; the catalytic reactivity of the sensor, when contacted by a gas containing a reducing constituent, i.e., H 2  or CO, and oxygen, is enhanced by employing RuCl 3  or PtCl 2  in predetermined quantities as a catalystwhich is uniformly distributed in the stannic oxide (powder) during production. The amount of the reducing constituent causes a change in the sensor resistivity measured by the current flowing in a local monitoring circuit using power supply (PS) and resistance (R). A potential drop measured by (MC) across the resistance (R) is indicative of the reducingconstituent content.

IPC: H05B41/392

Abstract: The invention provides a lamp driver circuit for discharge lamps, in particular fluorescent lamps. An inverter (12) receiving DC provides a high frequency AC output. A resonant circuit includes a capacitor (C25) connected across the lamp (13) and a ballast inductor (L2) in series with them. A control arrangement (15,16) causes the inverter (12) to operate at a frequency above the resonant frequency of the lamp when initially switched on. It is then caused to sweep down in frequency towards the resonance frequency so that the lamp strikes as a result of the magnified voltage applied to it. After the lamp has struck the frequency drops to a suitable running frequency. If the lamp strikes a circuit (L25, 201, 17) controls the frequency to limit the lamp voltage. Another circuit (DCT1, 203, P1, 17') controls the lamp frequency for dimming purposes. The circuit when operative at the initial higher frequency provides heating current through the filament before the lamp strikes since the capacitor (C25) shunts the lamp at such frequency.

Abstract: Enhanced recovery of oil from subterranean sedimentary formations by an in-situ combustion method employing a pattern of an injection well and several production wells, spaced-apart by a treatment zone. Combustion is controlled by placing at least one fluid conduit in a treatment zone and introducing a control fluid through it to modify the flame front. Oxygen may be introduced to take over from combustion air initially introduced through the injection well, to sustain combustion and advance the flame front. Water may be injected through the injection well, alternating with the oxygen through the control conduit to continue a wet combustion method started with air. The strategic placing of control conduits and the introduction of appropriate fluids may be employed to improve the sweep geometry by advancing the flame front or retarding it, or invading areas behind it. Safety means is provided for introducing the oxygen at a velocity greater than the maximum flame velocity encountered in the flame front.
