Abstract: NEW AND IMPROVED COUPLING APPARATUS            Abstract of the Disclosure For use in connecting first and second pipes, an apparatus which incorporates an external sleeve adapted to be abutted against a flange and positioned about a first pipe and enclosing oppositely facing sets of tapered slips.         The slips incorporate serrations to enable them to grip the first pipe.  An encircling cavity receives fluid under high pressure and hydraulically forces the two sets of slips to an actuated position, firmly gripping the first pipe.  This provides a good mechanical connection of the connector to the first pipe.  The second pipe is preferably connected to the flange.  A separate set of fluid seals prevent leakage.          They are actuated by means of a second set of pistons which hydraulically force the seal members with adequate pressure to cause them to seal the connection of the first and second pipes.  The coupling apparatus has a separate mechanical coupling and an isolated seal mechanism which are separately actuated.

Abstract: Abstract of the Disclosure Temperature indicating apparatus having a sensor for introduction into a region having a tempera-ture to be measured and for supplying an analog signal whose amplitude is a function of the temperature therein. The analog signal amplitude is compared with a reference level which represents a preselected temperature level, and a signal is supplied when the analog signal amplitude reaches the reference level which thereby causes pulses to be supplied at a predetermined rate.  A timer respon-sive to the pulses counts from zero to a preselected value and supplies a timing signal when the preselected value is reached.  The time required for the timer to count from zero to the preselected value establishes a predetermined timing interval at the end of which a converter responsive to the timing signal converts the analog signal to a digital signal representative of the temperature in the region. Display circuitry responsive to the digital signal provides a visual indication of the temperature in the region being measured, this temperature being displayed only at the end of the predetermined timing interval.

Abstract: ABSTRACT A sterile or sterilisable container in which the contents are sealed hag a wall provided by a rupturable membrane.   Preferably the outer surface of the membrane is covered by a layer of sheet material peelably adhered thereto   To dispense the contents, another rupturable sheet is adhered to the membrane, having first removed the covering layer if present.  The surface of said rupturable sheet remote from the membrane is sterile, and a sterile cutting tool is used to cut through the two rupturable layers to create an opening through which the contents can be discharged.  The potentially contaminated outer surface of the container membrane is thus sealed to the adjacent surface of the rupturable sheet, which could also be contaminated, thereby minimising the risk of such contamination being passed to the contents as they are dispensed from the container.

Abstract: ENERGY TRANSFER                    Brandon H. Barton and John A. Sagel Abstract of the Invention This invention relates to a process for neutralizing detergent acid mixes containing unreacted sulfating agent such as sulfuric acid with an alkaline component such as sodium hydroxide.  The neutralization process is highly exothermic and contains as a by-product large amounts of sodium sulfate.  Due to the exothermic nature of the reaction it is necessary to use heat exchangers to regulate the temperature of the reaction mass following the addition of the alkaline component.  When the sodium sulfate is super-saturated in the reaction mass, it has been observed that sulfate salts buildup upon the surfaces of the heat exchanger and eventually the system must be shut down to remove the buildup.  This invention is therefore directed to a continuous neutralization and heat exchange process wherein the downtime required for removal of the sulfate salts from the heat exchanger surfaces is effectively eliminated.
