An improved safety-valve capable of being changed over from the service position to the safety position by a blow or pressure on the valve cap and comprising a seating, a shut-off member with a closure position applied against said seating and an opening position spaced apart from said seating, a spring urging said shut-off member towards the safety position, a first means for bringing the shut-off member into the service position against the action of said spring and being capable of being put ...

The instantaneous trip means for a circuit breaker is constructed with an electromagnet having a movable armature biased away from a stationary yoke. A biasing spring for the armature acts on the armature through a pivoted trip lever. One end of the biasing spring is connected to the trip lever at a point very close to the pivot for the trip lever, and the line of action for the spring is so positioned that as the armature moves toward tripping position increased loading of the biasing spring is...

In accordance with the present invention an instantaneous delivery film useful in the delivery of a therapeutic agent to a wound site is provided. The present delivery film comprises a therapeutic agent, e.g. an enzyme or medicament, incorporated into a delivery material which forms the film. The delivery material is capable of rapidly dissolving in aqueous and saline solutions and comprises a water soluble and nonaqueous-solvent soluble film-forming polymer in an amount of from about 20 to abou...

A compensation circuit includes a circuit for monitoring the current delivered to a load and for producing a switching signal whenever a current spike is detected. A control signal representative of the desired voltage across the load is produced. A power supply supplies voltage to the load in response to the control signal. The circuit for generating the control signal is responsive to the switching signal for adjusting the control signal such that when a current spike is detected the voltage d...

This invention relates to a counter-countermeasure for use in radar systems nd more specifically to a circuit which is capable of giving an indication of the range of a target notwithstanding the fact that the target is jamming the radar equipment.

Method and apparatus for the real time detection of the formation of ice on a surface in which a sensor having spaced electrodes along the surface is embedded in the surface for which detection is to be provided. Resistance between the electrodes is monitored and electrode temperature is monitored. When a sharp rise in resistance on the surface due to the presence of ice is detected at the same time that the surface temperature is at or below the freezing temperature of water, then a computer pr...

Disclosed here is a method for the removal of all types of human and animal skin warts using a technique of cauterization wherein slaked lime is applied to wart and then the surface of wart is scratched by using the stem of betel leaf.

Positive and negative ion output are balanced in an electrical ionizer having positive and negative ion emitters, and positive and negative high voltage power supplies associated with the respective positive and negative ion emitters. At least one of the positive and negative high voltage power supplies switches between a high state and a low state. An ion balance sensor is located close to the ion emitters and outputs a voltage value. An ion balance sensor set point voltage value is stored. The...
