Inventor: POSTHUMA ALBERT E
IPC: A61K47/32
Filed: 1979-11-23
Abstract: The agent is based on a dilute solution of highly polymeric anionic polyacrylamide in water. The solution is clear, of moderate viscosity, non-toxic, sterile and can additionally contain preservatives, bacteriostatics, pharmaceuticals and stabilisers. The solution is used as substitute for human mucus in the vaginal region, as lubricant and antifriction agent for medical instruments, especially those introduced into the body (catheters, tracheoscopes, endoscopes), as antifriction agent for suppositories, as film-forming and reactivatable preservative of other surgical instruments and as medium and vehicle for pharmaceuticals in general. The lubricants and antifriction agents are stable on storage and can vary within wide limits of pH and viscosity.

Abstract: A fluid shear coupling is disclosed herein which comprises a coupling disc received within a housing. The coupling disc and housing are mounted for coaxial rotation, and the coupling disc is connectable to a drive pulley assembly for driving the coupling disc in rotation. The coupling disc includes a pair of annular flanges extending axially in opposite directions from the periphery of the disc. The flanges define inside and outside working surfaces with the inside and outside working surfaces including helical grooves for moving a fluid received against those surfaces in a predetermined direction. The housing includes working portions closely conforming to the working surfaces of the flanges. A fluid reservoir is defined by the housing and is operable to move a working fluid into the space between the flanges and the working portions of the housing to provide variable coupling of the housing with the coupling disc.

Abstract: In the device a p<-> diffusion region 3 is formed between p-type base 6 and p<+> isolation diffusion 5. There is a junction between collector region 4 and p<-> diffusion region 3. When the potential of collector region 4 is less than that of p<-> region 3, region 3 provides a path for discharge of carriers from base 6 to isolation diffusion 5 to speed up switching. When the potential of collector region 4 is higher than that of p<-> region 3, the depletion layer at the junction pinches off the path and isolates the base 6 from the isolation diffusion 5. 
<??>The p<-> region 3 may be replaced by an extension of the base region 6 up to the isolation diffusion 5. 
<??>An n<+> region, shorted to collector region 4, may be formed over p<-> diffusion region 3 to provide another junction for pinch off of the path. 
<??>The path may alternatively provide for carrier discharge to p-type substrate 1.

Abstract: A stream of internal combustion engine effluent gas is analysed for combustible or combustion-supporting constituents by separately in time passing an untreated sample of the gas and a sample treated by addition of whichever of a combustible and a combustion-supporting constituent it is deficient in through a reaction zone maintained in conditions effective to cause mutual reaction of combustible and combustion-supporting constituents and containing a temperature sensor, and measuring the difference in temperature between untreated and treated samples as the result of subjection to those conditions. 
     According to the drawing a stream of exhaust gas is equilibrated in zone 15 and divided into two streams, one of which receives an addition of gasoline vapour in chamber 228, while the other passes through chamber 22A without addition. Then the streams from chambers 22A and 22B are passed alternatingly over hot wire 30 by the action of valve 27 actuated by external electromagnet 29.

Abstract: Biaxially oriented tubular articles which are destined to provide bodies for processable food containers are made from an elongate tube of thermoplastics material as it emerges from an extruder. The manufacturing process comprises repeatedly performing a cycle of operations each including the following steps: 
     engaging the tube by a first clamping means (11,12) over a first region at a leading end of the tube (10) and by a second clamping means (13,14) over a second region at a spacing from the first region, so as to define between the clamping regions a portion of the tube to be longitudinally stretched and radially expanded; 
     moving the clamping means apart to stretch the tube portion longitudinally and admitting pressure fluid to the tube portion to expand it radially, such stretching and expansion forming a bubble (100) of biaxially oriented thermoplastics material adjacent the leading end of the tube; and 
     severing (at 22) at least a substantial part of the bubble from the tube to form the tube with a new end as the said leading end of the tube for the succeeding cycle of operations.

Abstract: A control system for use in a valve bag filling apparatus eliminates sifting of product during the filling process. A filling nozzle (10) is inserted into the valve of a bag to be filled. A flow of particulate material is provided through the filling nozzle (10) and into the bag. When the bag is full, the flow of particulate material is terminated. A blast of high pressure air (46) is then introduced into the nozzle (10) in order to clear the nozzle of any residual particulate material therein. A low pressure blast of air (23) is introduced between the nozzle and the filling valve to suspend any particles present in the filling valve after the nozzle has been cleared by the high pressure blast (46). A vacuum is introduced into the nozzle to suck any suspended particles out of the filling valve after the low pressure blast has been introduced. An inflatable boot (14) can be provided on the nozzle (10) to seal the nozzle within the valve of the bag during filling. Control of the system is effected by electro-pneumatic components.

Abstract: U7 In a method and apparatus for producing a foamed polymeric sheet having comparatively high density skin layers and a comparatively low density core layer, molten polymer containing a foaming agent is extruded from a die 18 into a post-extrusion region 22 defined by the die 18 and a spaced pair of rotating chill rolls 24 which are spaced from the die 18. The post-extrusion region 22 is maintained at a pressure sufficient to at least inhibit expansion of the foaming agent through the use of cooled sealing elements 26 which occupy a substantial portion of the space between the die 18 and the chill rolls 24, and are spaced from the chill rolls 24. The rolls 24 and the sealing elements 26 are cooled so that molten polymer in the space between the sealing elements and the rolls becomes solidified, completing the seal. The chill rolls 24 are maintained at a temperature below the temperature of the molten polymer to aid the skin formation on the surfaces of the polymer. If desired, the polymer can pass directly from the chill rolls into a water bath.
