Abstract: A ventilating system includes a high frequency controlled breathing gas source in HFJV operation, wherein the exhaled gas is removed through an outlet line through which a flush gas is conducted, is improved to permit a determination, under high frequency ventilation, of both the final expiratory CO2 concentration and the basic pressure building up in the lungs (the lung-internal PEEP). To this end, the control device is in addition connected to a flush gas valve provided upstream of the breathing gas supply device, and designed to intercalate a measuring interval after a sequence of breathing gas pulses, during which interval the breathing gas valve and the flush gas valve are closed. A system of measuring the breathing gas valves is provided in the outlet line and it is actuated during the measuring interval to perform the measuring operation.

Inventor: DUBROW ROBERT S
IPC: B29C71/04
Filed: 1986-04-30
Abstract: This invention provides organopolysiloxane materials having cone penetration between about 100 and about 350 (10- <sup>1</sup>mm) and ultimate elongation of at least 100% and having reduced surface tack. This invention provides three methods of obtaining said materials with reduced surface tack. The first method comprises applying to the surface of such material an organic peroxide or a photoinitiator and irradiating the surface with ultraviolet light to further crosslink the surface to reduce or eliminate the tack of the surface. The second method comprises mixing a photoinitiator, such as benzophenone, in an organopolysiloxane fluid, thermally crosslinking the organopolysiloxane fluid to produce the material with the above cone penetration and ultimate elongation then irradiating the surface of the material with ultraviolet light to reduce or eliminate the tack of the surface. The third method comprises mixing a photoinitiator, such as benzophenone, in an organopolysiloxane fluid, crosslinking the fluid by irradiating a layer of the fluid with ultraviolet light to produce the above cone penetration and ultimate elongation properties then further irradiating the crosslinked material to reduce or eliminate the surface tack; this method can be carried out by simultaneous irradiation with ultraviolet light from two sides of a layer of the organopolysiloxane wherein one surface is irradiated at a higher intensity than the other surface. The materials produced by this invention are useful as tapes and sealants.

IPC: G01V5/10
Filed: 1991-04-24
Abstract: The porosities of subsurface earth formations surrounding a borehole are investigated using a logging tool run in the wellbore by repeatedly irradiating the formations with discrete bursts of high energy neutrons, measuring the populations of epithermal neutrons at near and far locations from the neutron source, and also measuring the rate of decay of the epithermal neutron population at a third location following each neutron burst and deriving therefrom a measurement of the epithermal neutron slowing down time. Formation porosity values derived from the near-and-far location population measurements are corrected for detector standoff effects by use, in accordance with a predetermined empirical relationship, of the epithermal slow down time measurement. Alternatively, formation porosities may be derived both from the near-and-far location measurements and from the epithermal slowing down time measurement, and the two differently-derived porosity values may be used independently to provide enhanced information of formation porosity or they may be compared to derive a standoff-corrected porosity value. <IMAGE>
