Abstract: ABSTRACT OF THE DISCLOSURE     In producing hollow bodies by blow molding from thermo-plastic material, a preferably tubular preform is firstly formed, and is then expanded within the blowing mold under the effect of an inert gas under high pressure, until it bears entirely against the inside surface of the blowing mold. There-after, a reaction gas such as fluorine is introduced into the hollow body under a considerably lower pressure, while the hollow body is still in the mold, to treat the internal surface of the hollow body to render it impervious to gas and/or liquid. After the reaction has elapsed, a flushing and cooling gas is introduced into the hollow body and is then removed from the blowing mold after the hollow body has sufficiently set.

Abstract: ABSTRACT           A brake booster (16) includes a pair of pistons (50, 56) and a valve assembly (74) operable to communicate fluid pressure to the pair of pistons (50, 56). An input assembly (90) moves in response to an input force to control the operation of the valve assembly (74).  Movement of the valve assembly (74) allows fluid to be  supplied to working  chambers (52, 58). Resilient means (133, 135) acts on and holds pins (130, 132) against the pistons (50,56).  When the fluid pressure in the working chambers (52, 58) acting on the pins (130, 132) is sufficient to overcome the resilient means (133, 135) an increase in the fluid pressure in chamber (52, 58) moves the pins (130, 132) into engagement with the input assembly (90) to oppose movement of the input assembly (90) since a desired brake force has been generated.

Abstract: ABSTRACT OF THE DISCLOSURE         A solution polymerization process for the preparation of high molecular weight polymers of alpha-olefins selected from the group consisting of homopolymers of ethylene and copolymers of ethylene and C3 -C12 alpha-olefins is disclosed.  The process comprises feeding monomer(s), coordination catalyst and inert hydrocarbon solvent to a reactor, polymerizing the monomers at a temperature of up to 320°C and a pressure of less than 25 MPa, and deactivating the catalyst in the solution so obtained.  The catalyst is deactivated by sequentially admixing therewith (a) a minor amount of a first deactivator, (b) a solution of a salt of an alkaline earth metal or zinc and an aliphatic monocarboxylic acid dissolved in hydrocarbon solvent, and (c) an organosilicon compound.  The solution of (b) and the compound of (c) may be combined.  The first deactivator may be water, a nitrogenous base or carbon dioxide or the like.  The organosilicon compound is of the formula SiR'n(OR)")4-n where R' and R" are alkyl or cycloalkyl and n is 0-3.  The hydrocarbon solvent and other volatile matter are then separated from the resultant solution and a composition comprising said high molecular weight polymer is recovered.

Abstract: ABSTRACT OF THE DISCLOSURE In a Tension Leg Platform, the common practice is  to  locate the well and anchor templates on the sea floor.   This  practice  results  in  unequal  lengths  for the  mooring  elements which  extend  to  the  base  of  the floating  structure  and the well risers which extend to a well  deck level which is  elevated above the base of the  floating  structure.   As  a  consequence,  complicated tensioning  systems  having  an  extremely  long  stroke may be required for the well risers.   The present invention provides  for  a  well  template  which  is  elevated  above the anchor templates at a level which equalizes the lengths of the mooring elements and the well risers.   The well and anchor templates are constructed in a unitary structure to  facilitate  installation  and  assure  proper  spacing of the templates with respect to each other.  In preferred embodiments of the invention,  subsea storage is provided as  well  as  curved  conductors  which  facilitate  angular deviation  of  the  wellbores  away  from  the  template  and J-tubes for the pull-in of subsea flowlines.

Abstract: ABSTRACT         This invention relates to an improved process for the preparation of poly(alkylene carbonate) polymer by the reaction of alkylene oxide with carbon dioxide and/or an alkylene carbonate at an elevated temperature and pressure.  The improvement comprises conducting said reaction in the presence of a catalyst mixture comprising an alkaline catalyst and a stannate com-pound.  It is preferred to employ either ethylene oxide or propylene oxide because they are generally most reactive and give rise to the fewest by-products.  Of these two, ethylene oxide is most preferred.  It is also preferred to employ either sodium stannate or potassium stannate as the stannate compound and potassium carbonate, sodium metaborate, potassium 33,205-F     hydroxide or potassium metaborate as the alkaline catalyst.     33,205-F

Abstract: Abstract Sealing the backside of a semiconductor wafer prevents evaporation of the dopant (typically boron) when an epitaxial layer is grown on the front (active) side, thereby preventing autodoping of the epitaxial layer with excess dopant. The present technique deposits an oxide layer during the ramp-up of the furnace that also deposits the nitride cap, thereby avoiding an extra process step. It also avoids the higher temperatures required for the prior-art technique of growing the oxide layer, resulting in lower oxygen precipitation due to the capping process and a greater yield of usable wafers.

Abstract: A method and apparatus for inspecting a danger alarm system, such as a fire alarm system, having a plurality of discrete alarm units which are connected to a central station having a means for cyclically sampling and connecting the alarm units to a like plurality of evaluators permits the alarm units to be connected individually or in groups to an inspection display without suppressing the display of an actual alarm signal which may be received during the inspection. A first report of an alarm unit to be inspected is evaluated as an inspection report and an actual alarm report from the same alarm unit arriving after the inspection report is evaluated and displayed as an alarm report. Given alarm units which emit multi-level or analog signals, the alarm unit signals are evaluated in the central station with two threshold circuits, the evaluator at the central station being switched during an inspection to a less sensitive state and the inspection signals being evaluated by a lower threshold stage and a true alarm signal which may occur during an inspection being evaluated as such by an upper threshold stage.

Abstract: A porous material (for example paper) has pores in a range of sizes. A pore-modifying agent (comprising particles in a narrow size range) is selectively incorporated into the larger pores to produce zones with heightened surface area. These heavily reduce the permeability of the material (for example of microorganisms), whilst they have relatively little effect upon its air permeability. The modifying agent can be incorporated by creating a pressure difference across the material and treating it with a dispersion (for example an aerosol) of the modifying agent under low- inertia conditions and by merely incorporating a small quantity of the agent (less than 1 percent by weight). <IMAGE>
