摘要： 629,009. Resistance and capacitance measurements. BURKETT, R. H. W., and WELWYN ELECTRICAL LABORATORIES, Ltd. Feb. 26, 1947, No. 5510. [Class 37] Components to be tested are mounted in a conveying mechanism which presents each component in turn to testing terminals, means being provided for holding the component until after the testing operation, the testing apparatus operating means for dropping the components into receptacles in accordance with the result of the test. In the construction shown a drum is divided into eight screened compartments and is rotated by a stepping mechanism so that each compartment in turn is presented to a screened chamber 5. Each resistor to be tested is dropped into a compartment and rests in a cradle 6 with its leads in close proximity to terminal blocks 7. A pivoted assembly 9 is arranged in each compartment and is shown in compartment 10. When a lever 12 engages a cam track 13 the assembly pivots about a shaft 14 and presses the resistor leads against the blocks 7. In this position the resistor is carried round .to the compartment 5 where the test is carried out. If this is satisfactory the resistor is released and falls into a hopper 17 when the lever 12 disengages from the cam track 13. If the resistor is unsatisfactory the detector operates a solenoid 18 which prevents release of the resistor until it engages a cam 19, which allows it to fall into a hopper 20 for rejected resistors. A number of solenoids 18 may be provided so that resistors may be sorted into various grades. The invention is also applicable to the measurement of the capacitance of small capacitors and the temperature coefficient of resistors.

摘要： An apparatus for producing a closely-controlled flow of vapour, e.g. of ethyl alcohol comprises an electrically-heated vessel having a restricted vapour outlet, wherein the pressure is thermostatically controlled by the rate at which energy is supplied to the heating element. A metal vessel 1 is closed by cap 4 in which are inserted capillary tube 5 and tube 7 for supplying liquid to the vessel. The vessel is wound with an electric resistance element 8 divided into three sections, and between these sections are two thermostatic windings 9 of metallic material having a high temperature coefficient. The thermostatic winding is connected to a bridge circuit, one arm of which is variable so that the temperature at which the bridge may be balanced is variable over a small range. The output of the bridge is applied either to a sensitive relay or to an amplifier, so that the power applied to the heater-winding can be varied to maintain the temperature of the vessel within close limits. A heater-winding 10 is applied to tube 5 to prevent condensation of the vapour. The apparatus is adjusted to maintain the temperature of the vessel a few degrees above the boiling point of the liquid which is to be vaporised. The heater and thermostat windings may alternatively be inserted beneath the surface of the liquid. The apparatus may be used to introduce a reagent into a chemical reaction chamber or to introduce a small quantity of odoriferous vapour into a large body of dangerous but odourless gas, so that leakages of the dangerous gas may be detected.

摘要： An optical transmitter includes a light source and an SBS suppression circuit coupled to the light source. The light source is operable to generate an optical signal having one or more wavelengths. The optical signal has a signal spectrum having an upper band limit and a lower band limit. The SBS suppression circuit is operable to communicate a noise current for receipt by the light source. The noise current is operable to broaden the signal spectrum of the optical signal. The light source operates to convert the noise current into a noise component of the signal spectrum that resides between the upper band limit and the lower band limit.

摘要： A space heater with a linear source of infrared radiant energy in heat exchange relationship with a heat exchanger formed of copper or aluminum material. The copper is pretreated to soften the copper and partially blacken the surface thereof. The aluminum is anodized and electrolytically colored dark. The space heater is thermally more efficient than a comparable space heater wherein the copper or aluminum has not been pretreated. The linear source of infrared radiant energy and heat exchanger are mounted in a heater core that is thermally insulated by an air jacket from an exterior case.

摘要： A foam body structure formed of plastic foam with one or more flame retardant reception cavities formed in the main body either simultaneously with an initial foam body formation process such as expandable plastic bead molding or subsequent to the foam body formation such as by melting, drilling or cutting. A solid flame retardant such as one in granular form is preferably supplied in sufficient quantity as to entirely fill the volume defined by the reception cavities. A covering or coating is provided over the flame retardant material to fix the material within the cavities. The volume and distribution of the reception cavities and the amount of the chosen flame retardant received in the cavities is sufficient to provide an essentially common flame retardation quality or characteristic over the entire volume of foam body (or at least the volume that could be exposed to a flame in its intended use).
