Patent EP-0259689-A1 (EP)
Inventor: KLEIN RICHARD G
IPC: B29B7/72
Filed: 1987-08-25
Abstract: A method and apparatus for controlling the gas content of dispensed hot melt thermoplastic adhesive foam. Air or another relatively inert gas is mixed with molten thermoplastic adhesive, and the mixture is pressurized to form a gas and molten adhesive "solution". When the molten adhesive and gas "solution" is dispensed at atmospheric pressure, the gas is released from "solution" and becomes entrapped in the adhesive in order to form a homogeneous closed cellular adhesive foam. In order to control the gas content of the dispensed adhesive and gas "solution", in accordance with one preferred embodiment, the pressure drop across a restriction in the flow path of the solution is sensed, and a control circuit controls the addition of gas to the adhesive to maintain the sensed pressure drop at a desired level. Other sensing techniques can be used to measure a parameter of the dissolved gas/molten adhesive single phase liquid solution which is correlated to the dissolved gas content of the solution and substantially indepen­  dent of the molten adhesive content thereof, such as measuring the transmittance of infrared radiation through the gas/adhesive single phase solution at a wavelength relatively heavily absorbed by the gas and unabsorbed by the adhesive.

Abstract: This invention relates to a class of alkenylated toluenediamines and phenylenediamines having at least one alkenyl group  ortho  to an amine group. More particularly the aryldiamines are represented by the formula:
      wherein R is hydrogen or C₁-C₃ aliphatic, R₁ is hydrogen, R₂ is C₂-C₄, and R₁ and R₂ form an alkylene radical (CH₂) y  wherein y=3 or 4, and x is one or two. 
     The above described alkenylated aryldiamine, hereafter referred to as diamino-β-alkyl styrenes, have been found to be well suited as antioxidants and as tri-and tetra functional chain extenders in forming polyurethane/urea elastomers systems and for providing pendant unsaturation for post curing and polymerization.

Abstract: A method and apparatus for smoothing raw oscillometric table data in the region around systolic blood pressure to reduce respiration interference is disclosed. Systolic blood pressure is determined by averaging intermediate pressures values associated with dual thresholds (TH.L, TH.H) instead of a single threshold (TH.S). Interpolation is used between adjacent applied cuff pressure values having table entries located on either side of each of the upper (TH.H) and lower (TH.L) threshold values. Normalization of the table is employed to improve interpolation resolution.

Abstract: A gas sampling system for a coal mill has a filter shield assembly (30) for a flexible filter (24) attachable to the probe of the gas sampling system. The filter shield assembly (30) is offset from the filter (24) to provide sufficient gas flow along the sides of the filter (24) to set up gas currents for flexing or fluttering the filter to dislodge any particulate matter trapped in the filter. The filter shield assembly (30) comprises inner and outer spaced concentric shields with the outer shields overlapping the spaces between the inner shields thereby to prevent particulate matter from entering the analyzing system and preventing direct impingement of particulate matter on the filter (24).

IPC: H01L21/365
Filed: 1988-04-11
Abstract: Alternate layers of CdTe and HgTe are deposited on a substrate in a reaction zone inside a reactor vessel using a method involving the steps of (a) passing a gas stream containing a volatile tellurium compound (Et₂Te) over the substrate while maintaining an atmosphere of mercury vapour in the reaction zone, and (b) switching on and off a separate supply of a volatile cadmium compound (Me₂Cd) to the reaction zone so as to deposit CdTe when the separate supply is on and to deposit HgTe when the separate supply is off (O). The surface of the substrate is irradiated with electromagnetic radiation (UV) the intensity of which is switched during the deposition. The irradiation intensity (UV) is reduced, possibly even to zero (0), when the supply of the volatile cadmium compound (Me₂Cd) is switched on. When the cadmium supply (Me₂Cd) is switched off (O), the irradiation intensity (UV) is increased to promote photodissociation of the volatile tellurium compound (Et₂Te) by the electromagnetic radiation (UV). This permits the layers to be grown at a low substrate temperature, while avoiding premature nucleation of CdTe in the gas stream. The switching of the radiation intensity (UV) may be effected using a mechanical shutter to switch off (O) the irradiation (UV) or using an adjustable iris or movable neutral-density filter to reduce the UV intensity. The alternate layers may be interdiffused during growth to form a cadmium mercury telluride layer for an electronic device, for example an infrared detector or a bipolar transistor. Alternatively, the alternate HgTe and CdTe layers may be preserved in the final device, for example as a "superlattice".

Abstract: In gas-cooled electric machines with a closed cooling loop which is distributed over two heat exchangers, arranged on the upper or under side of the machine, only part of the circulating cooling gas is cooled so that the electric machine must be taken out of operation because of the danger of local ovewrheating. In order to overcome this, baffles are arranged adjacent to the heat exchangers so as to block the cooling gas on half the side of the opposite axial cooling gas passage regions of the heat exchangers, thus subdividing the cooling gas stream into two halves with opposite flow directions. The partial transfer of the cooling gas stream halves to the entire width of the axial cooling gas passage areas of the heat exchangers provides turbulence and a distribution of the cooling gas for uniform cooling also in the event of a failure of one heat exchanger.
