A seal member is positioned at the air outlet and there is a chamber within the body which connects the inlet and outlet. A valve plug is movable within the chamber toward and away from the seal member along a path coaxial with the outlet and the seal member. The valve plug has portions thereon which cooperate with the seal member to close the outlet. A handle is located outside of the gladhand body and is operatively associated with the valve plug for effecting movement thereof between open and closed positions.

Abstract: A cooking station for gas ranges whose burner works with super-stoichiometric combustion air premixing. The burner head arranged in a burner tray is connected with a mixing pipe via a ceramic insulating ring. Between the burner head bottom and the burner head lid with the flat topside, we have two perforated flame opening rings which are arranged concentrically with respect to the burner axis, which are resistant to heat and which are resistant to oxidizing and reducing atmospheres. The perforation of the inner flame-opening ring is so dimensioned that the flames cannot backfire. Below the burner tray there is arranged a reflector. The cooking station can be covered with a glass ceramics plate. The invention achieves stable flame performance, perfect combustion, and waste gas poor in harmful substances at nominal load and at small adjustment heat load within a vast utilization field of gases with differing Wobbe indexes as well as a start-up cooking efficiency improvement compared to known burners.

Series of mirrors are provided for use in conjunction with the solar collector and pre-heater to provide further improvements, a first series of mirrors primarily serving to amplify the quantity of incident solar radiation delivered to the solar collector and pre-heater, and a second series of mirrors primarily serving to compensate for movement of the sun with respect to the solar collector and pre-heater throughout the day.

Abstract: A valve mechanism for positive displacement, rotary receptacle filling machines having vertically movable valve stems operable by fixed cam tracks employs cam followers pivoted on the valve stems for movement in a vertical plane and horizontally settable means for locking them against such movement.

Abstract: The invention relates to a combustion catalyzing system for commercial grade fuels. The system comprises a water reservoir which is fed with air through an inlet arranged to be immersed into the reservoir water. A vapor phase water outlet conduit is provided which extends from the reservoir top and is routed to a combustion zone to be catalyzed. Along the path followed by the vapor phase water which flows through the outlet conduit from the water reservoir, an oil-operated flow regulating device is provided which is effective to control the rate of emission of steam bubbles from the reservoir. Upstream of the flow regulating device, a motor-driven valve controlled by a humidistat located in the proximity of the combustion zone to be catalyzed may be provided for delivering a larger or smaller amount of steam to the flow regulating device.

Abstract: High-velocity gas burners having enhanced flame stability over wide operating ranges are provided by correlating the dimensions of the combustion chamber with other burner dimensions, in particular, the ratio of the combustion chamber diameter to the flame holder exit diameter and the ratio of the effective length of the combustion chamber to the combustion chamber diameter.

Abstract: A fire flap arrangement for installation in a flow channel comprises a housing with opposite front walls and openings in the front walls. A pair of fire flaps are pivoted in said housing and held by means of permanent magnets in rest positions outside of the flow area. A locking bar within the housing can be displaced radially inwards pivoting the fire flaps into their locking positions in which they close the front wall openings. The locking bar in its locking position bridges the pair of fire flaps and presses them outwards against the front walls. The arrangement is actuated by a liquid pressure driven piston, the liquid also serving as a cooling medium for the housing.

Abstract: An electromagnetic valve which can control a fluid flow in dual mode, i.e. a small amount of fluid at a first step and a large amount of fluid at a second step, which adopts a bypass means of magnetic flux for obtaining the first step and a resistance means that does not allow the magnetic flux to flow in the first step while it allows it to flow in the second step for obtaining the second step.

Abstract: A diaphragm operated valve assembly is controlled by an electromagnetic valve assembly. A flat disc armature, which forms part of a flux path, is operable in an inner chamber to modulate the flow between the inner chamber and an exit port in response to an applied magnetic force. The level of the effective magnetic force is a function of the armature mass, the pressure acting on the disc surface and the magnetic reluctance. A pole piece adjacent to the flat disc armature includes a seat and is at a fixed distance from the armature.Variation of an air gap provides a means to adjust the magnetic reluctance of the electromagnetic valve after its final assembly and in this case an adjustment air gap is provided at the top member of the flux path. Such valves may thus be calibrated to operate at various pressure or flow rates as a function of electrical power input, that is a variation of current or voltage.

Abstract: A method for detecting the operation of a burner uses the rectifying effect of the burner flame, when an alternating voltage is applied between the burner (1) and an electrode (2). A control device (18) is connected to the primary of an isolating transformer (6) which receives a high frequency alternating voltage from a generator (7). The current rectified by the flame provides dumping of the circuit at the secondary of the transformer which is used to detect the presence of a flame. An igniter (25) may be connected to the same electrode of the burner via an element (28) whose resistance varies with the voltage.

Abstract: A solar-heating system incorporating a photosensitive sensor locatable remotely from the collector panels but similarly oriented with respect to the solar-energy source, such photosensitive sensor being biased by one or more biasing resistors of predetermined magnitudes and temperature coefficients so that the combination, in its performance with respect to ambient temperature and (optionally) with respect to ambient wind velocity, matches the thermal characteristics of the solar energy collection system so that the solar-energy collection fluid is pumped only when it can contribute heat energy to the already stored solar-heated fluid.

Abstract: The dual cannister gas housing of the present invention permits combustion of two separate gases of different heating values for industrial applications. The housing includes a first annular chamber surrounding a combustion zone, the first chamber receiving a first gas. Holes in the inner wall of the chamber permit entry of the first gas into the combustion zone. A second chamber surrounds the first chamber and receives a second gas. Tubes connect the second chamber to the combustion zone, the tubes passing through the first chamber to prevent mixing of gas. The number and size of the tubes and holes are selected for each application to insure proper entry velocity and pressure drop for the first and second gases.

Abstract: A photoflash device which includes a plastic substrate, lamp-firing circuitry located on a first surface of the substrate, a disconnect switch also secured to the first surface of the substrate and electrically joined to the lamp-firing circuitry, at least one electrically activated photoflash lamp located above the switch for activating said switch upon ignition thereof, and a solid, light-transmitting polymer located about and encapsulating the glass envelope of the lamp. A thin, light-transmitting polyester member is located over the switch to protect the switch during formation of the device. The polyester member serves to prevent contact between the resin which forms the polymer and switch during thisformation, thus assuring close placement of the lamp's envelope and switch, said placement thereby assuring proper activation (e.g., severance) of the switch.

Abstract: A non-drip candle is formed of three layers including a thick low melt point core and a thin outer confining high melt wax layer affixed to the core by a special intermediate layer. The intermediate layer formulation includes a paraffin candle wax in combination with a similar quantity of double pressed stearic acid and a high purity tallow acid in the range of 0.5 to 60% and preferably 5 to 10% by weight. A microcrystalline wax of about 5% increases the melt point and produces a smooth finish to the candle, and a resin of about 1% imparts hardness to the layer to permit processing. The candle burns with a shallow rim confining the wax pool about the wick and the multiple layer construction functions to practically instantaneously heal any breach in the rim as the result of deflection of the flame or physical engagement with the rim to establish a true dripless candle.

Abstract: A control valve for a resonant burner having a burner space for receiving active substance through a conduit with an atomizing nozzle discharging into the space is disclosed. When the valve is shut off to terminate flow of the active substance through the valve to the burner conduit, a spring action in the valve tends to withdraw the active substance from the conduit by creating a suction effect therein.

Abstract: Flow from the inlet chamber to the outlet chamber is regulated by the sleeve valve moving relative to the metering cone fixed in the valve body. The valve is guided in the stainless steel ring molded into the partition between the chambers. The valve is actuated by a hybrid linear actuator. The valve seats on the shoulder or flange and the effects of lift-off of the valve are minimized by the sharp edge on the valve and by the uniform diameter section of the metering cone. The sleeve valve is offset inwardly so the I.D. at the sharp edge is the same as the O.D. where the valve passes through the ring. This prevents loss of control of the valve. The valve hits a stop before the sleeve clears the cone and this prevents the valve from reaching a position in which the actuator and return spring have no effect.

Abstract: A warm air blowing heater includes combustion equipment for burning fuel, and an air duct provided at a position away from a portion directly above the combustion equipment for blowing air from the heater into the room. The combustion equipment includes a burner chimney provided above a burner, and a reflecting plate is provided behind this burner chimney. The radiation heat of the combustion equipment is radiated directly and is also reflected on the reflecting plate to heat the room. The air duct does not disturb the rise of the combustion exhaust gas of the combustion equipment to form a smooth rising exhaust gas stream. When the air is blown from the air duct toward the front of the heater, the high temperature air in the upper portion of the heater is sucked. This high temperature air is mixed with the air blown from the air duct to allow the heater to blow warm air into the room. The blower motor may suck the air in the room and supply it to the air duct.
