Abstract: ABSTRACT     Process and installation for the treatment of a stream of gas containing pyrophoric dust A stream of gas containing pyrophoric dust and oxygen is treated in a chamber that is equipped in such a way that care can be taken continuously that said stream of gas has for at least 1 second a temperature of at least 270°C and that the temperature of said stream of gas does not exceed 500°C.  Thereby, the pyrophoric dust, that is present in the stream of gas, is oxidized whereby it looses its pyrophoric character.  The stream of gas is now optimally conditioned to be filtered in a bag filter installation.

Title: Apparatus for measuring the peak voltage applied to a radiation source
Inventor: SHERIDAN TERRENCE E
IPC: H05G1/26
Filed: 1989-04-19
Granted: 1993-01-19
Abstract: Abstract Apparatus is provided for use in detecting the peak voltage applied to a radiation source operating at an unknown input voltage.  The apparatus includes a set of radiation absorbing filters including a first filter which includes a first element that exhibits a known K-absorption edge and a second filter constructed of a second element so that the filters exhibit essentially the same radiation absorption characteristics below the K-absorption edge of the first filter.  The filters are adapted to be positioned so as to be irradiated by  the radiation source so that the radiation impinges upon a surface of each filter and is partially absorbed as it passes therethrough so as to exit therefrom as attenuated radiation.  A detector, such as X-ray film or a pair of photodiodes, is positioned for receiving the attenuated radiation passed by the first and second filters and provides an output indication when the radiation passed by the filters is differently attenuated. This is indicative that the known K-absorption edge of the first filter has been exceeded, thereby providing an indication as to the magnitude of the voltage applied to the radiation source.

Abstract: MULTIPLE GLAZING                 Abstract of the Disclosure A method of manufacturing a multiple glazing unit  which  comprises:     preparing  two  transparent panels and assembling a spacer frame.   The frame has two parallel side portions  intended to be located in juxtaposed relation and parallel with the panels and a bridging portion extending between the side portions and intended to be located at the outer region of the spacer frame to provide a closed figure of substan-tially uniform thickness.    Prior to positioning the assembled spacer  frame between the two transparent panels,  a coating of a curing sealing composition is disposed onto the side portions, the bridging portions and corner pieces of the spacer frame.  The coating on the side portion is triangular in section.  The curing sealant  composition  comprises  a cold  curing  poly-urethane,  cold curing polysulphide or moisture curing silicone  and  has  a  rate  of  cure  and a degree  of thixotropy sufficient that the composition retains its shape and ability to bond until the panels are pressed together with the frame.    The spacer frame with its coating of sealant is then positioned between the two transparent  panels  and  these  are  then  pressed together.

Abstract: A reclining seat support (3) and a backrest support (4) are hinged on a chair frame with a support part (1) via a lever (7) by means of hinges (5, 8). Coupled to the backrest-side end of the seat support (3) is a link chain (15) which is connected at its other end to a slide (20) and a backrest (21). The link chain (15) causes the slide (20) to be moved downwards with the backrest when the chair is reclined. By this means, the pulling-out effect during the transition from the normal position into the reclined position of the lever is eliminated. However, if the chair frame is used as a chair without a link chain (15), although slightly less seating comfort is achieved by the reclining seat support, the expenditure is correspondingly less. <IMAGE>

Abstract: In a pressure swing adsorption system used to recover an oil-soluble solvent, monomer or hydrocarbon vapor such as 1,1,1-trichloroethane or styrene from a gaseous stream such as air, an oil-sealed vacuum pump may be used without substantial absorption of vapor into the oil if the oil in the pump is heated to a temperature substantially above the dew point of vapor in the gas stream leaving the pumps. Prior to this invention, oil-sealed vacuum pumps cannot be used to recover oil-soluble compounds because the vapor dissolves in the oil as the desorbed vapor and backpurge gas pass through the pumps. The thinning of the oil hurts the lubrication and seal within the pump and floods the pump.
