Title: Demand inhalation valve system
IPC: A62B9/02
Filed: 1979-01-31
Abstract: A valve body (28) defines a chamber (65) having an inlet (72) connected to a gas supply and an outlet (29) connected to a face mask. The valve body supports a flexible diaphragm (40) connected by an adjustable lever mechanism (59, 118, 110) to a piston (95) so that the diaphragm opens the piston in response to a predetermined differential pressure across the diaphragm produced by inhalation and respiratory gas flows into the outlet (29) through a radially extending passage (92). The valve construction is such that the piston opens further in response to a suction force produced by the flow of gas past the piston and independent of the diaphragm actuation to provide for minimizing the inhalation effort by the individual regardless of the volume of gas demanded during inhalation. This is achieved by providing an axial passage (102) in the piston and also by a Venturi effect produced when gas flows through a curved section of the outlet (29). <IMAGE>

Title: Apparatus for monitoring fluid level in a vessel
Inventor: ZASLAVSKY LEONID IOSIFOVICH
IPC: G01F23/14
Filed: 1979-08-02
Abstract: The apparatus comprises a nozzle 2 enclosed in a shroud 3 through which liquid is directed and means for sensing the variation in a liquid parameter caused by mixing of this liquid with the fluid in the vessel B, the ratio of the maximum size of the shroud to the distance of this maximum from the nozzle being less than 0.35. The fluid parameter may be pressure, sensed by a diaphragm 5 carrying a strain gauge or a pitot tube. Alternatively the pressure may be sensed in chamber 8 or upstream of the nozzle. The pressure changes when the fluid reaches level C-C and mixes with the liquid. With chamber 8 only connected via throat 9, the pressure change remains even when the level falls back below level C due to the flow being maintained divergent by the pressure in chamber 8. The chamber 8 may have a pipe extending up or down towards the fluid. <IMAGE>

Title: Crossunders for high density CMOS/SOS integrated circuits
IPC: H01L29/78
Filed: 1980-08-06
Abstract: A structure for a "universal crossunder" (48/58) which can reliably interconnect two spaced regions (44,46/54,56) of semiconductor material of the same conductivity type is described. The structure is comprised of two layers, one P type and the other N type which lies in the area between the regions which are to be electrically joined. Accordingly, whether the regions to be electrically connected are P type or N type, electrical connection is made between them through one of the layers of the crossunder. The method of making the "universal crossunder" entails, simultaneously introducing a fast diffusing impurity of one conductivity type and a slow diffusing impurity of the opposite conductivity type into the area between the regions to be joined. Thus, electrical contact between the two spaced regions will be made through one or the other of the layers of the circuit. <IMAGE>
