A method for producing a flexible polyurethane foam having reduced tendency to form burning embers, and which produces a char when it is ignited and burned, is provided by incorporating into the reaction mixture before foaming an aldehyde or an aldehyde generator, and preferably flexible polyurethane foam has increased flame retardance by also incorporating into the reaction mixture before foaming...

A solid-state electrosurgical generator is disclosed which provides output waveforms that are optimized for electrosurgical fulguration. The fulguration output circuitry consists of a radio-frequency tank circuit which is periodically pulsed to produce a periodic damped-sinusoidal output waveform. However, the damping factor is sufficiently low so that many cycles of the waveform occur between per...

An erodible sonde for detecting sand in the gas conveyed through a pipe. Such a sonde is constituted by a thin aluminium tube, one end of which communicates with a device for measuring the pressure outside the pipe and the other end of which is closed, the inner wall of this tube being in contact with a discontinuous prop or support means such as a steel spring with contiguous coils. Such a device...

Partial locking for a fluid-locked planetary gear used in a differential or the like is obtained by causing oil to be squeezed between the gears of a planetary gear train, thereby providing increased resistance to movement, or partial locking, of the gears within the gear train. Improved partial locking for a fluid-locked planetary gear train is provided by loosely mounting planet gears for moveme...
