A shaped gas-generating charge comprising a solid, substantially oxidizer self-sufficient, gas-generating grain and a combustion-restricting polymeric inhibitor containing a woven reinforcement and a vaporizable material to cool the polymeric inhibitor and to retard the decomposition of the inhibitor polymer to prevent the introduction of inhibitor decomposition products into the generated gas stream. Vaporizable material is present in the inhibitor in a concentration of from about 10 to about 5...

A circuit for generating high voltage comprising in combination an AC power source, an RC circuit, a pair of parallel connected switching element groups each consisting of at least one switching element exhibiting a negative resistance at a voltage in excess of a predetermined breakover voltage, pair of oppositely directed rectifier elements connected in parallel with each other to the junction of a capacitor and resistor of the RC circuit and in series to the pair of switching element groups re...

A deflection system for use with a color television multibeam cathode-ray tube utilizes a toroid deflection yoke with the distribution of the vertical and horizontal deflection windings being such as to provide a uniform deflection field within the toroid. An additional set of four series-connected, oppositely wound correction windings are wound on different quadrants of the toroid yoke; and a correction current is applied to the correction windings in the form of a current corresponding to the ...

A cylindrical, retarding potential difference type electron monochromator with exceptionally high energy resolution includes an electron beam source having essentially zero transverse velocity in a region that is maintained essentially free from magnetic fields. This device can also be used as an electron energy analyzer. In the electron spectrometer the electron beam passes through a chamber having a gas to be analyzed and then impinges upon an electron collector or electron energy analyzer. A ...

A square wave generating circuit for automatically deriving a 50--50 square wave output signal of constant amplitude from a random but repetitive input signal. An operational amplifier utilized as a Schmitt trigger converts the input signal into a rectangular output waveform which is clipped by a back-to-back zener diode arrangement and fed to an operational integrator. The output of the operational integrator controls the threshold levels of the Schmitt trigger in response to the duty cycle of ...

A condenser discharge type electrical pulse generating circuit, such as for a combustion engine ignition system, wherein two storage capacitors are charged in parallel to discharge across a relatively low-voltage trigger gap which connects the condensers in series to discharge across a higher voltage control gap and through a relatively low-voltage ignition gap which is connected in series with the control gap. The above circuit is disclosed herein as being used in combination with a second, alt...

A flexible heat-generating device is constructed by stringing a great number of mutually independent ferromagnetic rings around an insulated conductor line, and heat is generated by the secondary eddy current loss induced upon said rings when an AC current is applied to said conductor line.

A pulse generating circuit such as a monostable multivibrator, an astable multivibrator and a blocking oscillator is comprised by a first and second transistors, a source of current energizing collector electrodes of transistors and a temperature sensitive element serially connected with the collector resistors and the difference between the voltage drop across the temperature sensitive element response to the variation in the ambient temperature and the source voltage is applied to the base and...

A fluid piston/cylinder mechanism for generating oscillatory motion consists of a cylinder having an inlet port in one end and outlet ports in its walls, uncovered when the piston is remote from that one end, and an outlet port for fluid in the piston, which can be closed to hinder flow of fluid from the cylinder when the piston is adjacent the said one end of the cylinder, but opens when the outlet ports in the walls of the cylinder are uncovered. The closure member for said port may be a freel...

Apparatus particularly useful for preparation of foods wherein a portable steam-generating unit is adapted for cooperation with a proximate dry heat oven chamber to provide steam for controlled periods of time, and at controlled pressures.
