Abstract: ABSTRACT OF THE DISCLOSURE          Method and apparatus for continuously processing filled containers with liquid heat treatment mediums maintained under superatmospheric pressure by an over riding air pressure.  A minimum of liquid is used during processing with the liquid level being maintained above the containers at all times.  The liquid is controllably circulated through container filled tunnels defined within carts, from one end of the tunnel to the other, to assure equal heat treatment of all containers in the batch of containers in each tunnel.  The carts may either be non-agitating or agitating carts.  One embodiment of the con-tinuous pressure cooker and cooler includes a pressure vessel having two pressure locks to provide a pressure cooking chamber with high pressure cooling being performed in a mini-cooler defined by the outlet pressure lock followed by additional atmospheric cooling. Another embodi-ment of the invention comprises three- pressure lock means to positively divide the pressure vessel into cooking and cooling chambers; and a third embodiment substitutes a plurality of baffles for the intermediate pressure lock thereby effectively dividing the pressure vessel into a cooking chamber and cooling chamber.     -1a-

Abstract: ABSTRACT OF THE DISCLOSURE           A battery-powered fire alarm including a smoke detector, a controllable horn circuit and a battery monitoring circuit.  The smoke detector employs a pair of complementary field-effect transistor switches respectively connected to an ionization chamber and a potentiometer of a Wheatstone bridge circuit connected across the battery.  Unlike known circuits of this type, the field-effect transistors are biased off to minimize standby power consumption and are connected such that the threshold voltages thereof are offsetting to minimize supply voltage sensitivity of the detector. When the voltage from the ionization chamber assumes a value approximately equal to the potentiometer voltage, both field-effect transistors turn on to energize an alarm circuit to sound an alarm.  Hysteresis circuitry is provided to ensure that the complementary switches, once turned on, will not turn off and thereby terminate the alarm until after the alarm condition has terminated.  The battery monitoring circuit employs a pair of complementary field-effect transistors connected with each other to establish a reference voltage to which the battery voltage is compared.  An advantage over prior battery monitoring circuits of this type is that the reference voltage is a function of both the threshold characteristics of the field-effect transistors and the magnitude of a preselected control voltage.  Both field-effect transistors remain off until a low battery voltage condition is sensed to minimize standby power consumption.

Abstract: Abstract of the disclosure:     A process for treating resi-dues which result from the Wittig synthesis of olefins and which consist principally of methanol, triphenylphosphine oxide, salts and organic by-products, by steam-stripping the volatile constituents, with partial condensation of the steam, and separating the resulting aqueous-organic mixture at 80-100°C into a saline aqueous phase and an organic phase containing principally triphenylphosphine oxide. Using this process provides a simple method of freeing, from triphenylphosphine oxide and other organic impurities, the effluent from syntheses which result in the formation of triphenylphosphine oxide, and thereby on the one hand sub-stantially facilitates the purification of the effluent and on the other hand provides a simple method of recovering the triphenylphosphine oxide. The latter compound, which is easily purified by distillation or recrystallization, can then be used, for example, to prepare the triphenylphosphine required for  Wittig syntheses or to prepare the tri-phenylphosphine dichloride required for the synthesis of pesticides.

Abstract: PRESSURE OPERATED HYDRAULIC CONTROL VALVE Abstract of the Disclosure A pressure operated control valve operative to regulate the flow of fluid to a hydraulic modulating cylinder having a fixed hydraulic bleed which cylinder operates a mechanism for vary-ing the displacement of a compressor of an automotive air condi-tioning system to maintain a predetermined control or system pressure.  The system pressure continually surrounds a sealed bellows seated in the closed end of a tubular bellows cover.  High pressure fluid is continually supplied to the control valve which has a ball and seat to totally restrict fluid flow to the modula-ting cylinder when the system pressure exceeds the setting pressure of the valve.  When the system pressure drops below the setting pressure, the bellows extends against an axial pin which forces the ball from its seat, thus allowing high pressure fluid to flow to the compressor modulating cylinder operating the compressor mechanism and reducing the stroke of the compressor pistons.  When the system pressure returns to the setting pressure, the bellows retracts moving the ball toward its seat thereby reducing hydraulic fluid flow to the modulating cylinder.

Abstract: ABSTRACT OF THE DISCLOSURE         A cooling control system is described which is of particular value in controlling the cooling of various parts of an independent section glass-forming machine.  The control of the cooling air which passes through a duct is effected by a combination of a measurement of the cooling capacity of the air (determined by locating in the air flow in or near the duct a heated body and measuring its surface temperature) and the pressure of the cooling air supply.  The air flow through the duct is increased or decreased to maintain the pressure in the duct substantially at a pressure set point which in turn depends on the temperature measured at the surface of the body set in the cooling air stream.
