Abstract: ABSTRACT OF THE DISCLOSURE:     An improved process for disinfecting medical apparatus in an enclosure by the action of formaldehyde fumes subsequently neutralized by ammonia fumes.  The improvement comprises evacuating the formaldehyde fumes from the disinfection enclosure by the injection into the enclosure of a rinsing gas preheated to a temperature such as to avoid the polymerization of formaldehyde and formation of a parasitic deposit of trioxy-methylene, guiding the formaldehyde fumes towards an auxiliary chamber communicating with the enclosure and causing the neutralization of the formaldehyde and the formation of hexa-methylene tetramine to take place in the chamber by contacting the formaldehyde fumes with ammonia fumes for a period of time sufficient to ensure neutralization.  The process enables one to avoid the deposit of cristalline hexamethylene tetramine inside the disinfected apparatus.  The invention is also directed to an apparatus for carrying the above process, which comprises a dis-infection enclosure receiving the medical apparatus and provided with a source of formaldehyde fumes, a source of rinsing gas communicating with the enclosure and operative to evacuate the formaldehyde fumes from the disinfection enclosure, heating means for raising the temperature of the rinsing gas to a predetermined value at which the polymerization of formaldehyde and formation of a parasitic deposit of trioxymethylene are avoided, an auxiliary neutralization chamber communicating with the enclosure and provided with a source of ammonia fumes, the volume of the neutralization chamber being such as to allow the ammonia fumes to spread and come into contact with the formaldehyde fumes for a period of time sufficient to ensure neutralization, a pump connected to the disinfection enclosure and to the neutralization chamber and adapted to convey the formaldehyde fumes from the disinfection enclosure to the neutralization chamber, and a non-return valve allowing the formaldehyde fumes to be conveyed to the neutralization chamber and opposing the reverse return movement from the neutralization chamber to the disinfection enclosure.          The invention is particularly suitable for disinfecting artificial respirators.

Abstract: ABSTRACT OF THE DISCLOSURE     Pressure acting on the face of the poppet valve is opposed by a gas charge or a spring in the bellows.  The valve controls evaporator pressure in an automotive air con-ditioning system.  Destructive response to pressure pulses from the compressor is prevented by the static friction obtained by having a leaf spring bear on opposed sides of a self-lubricating plastic sleeve carried on a shaft fixed on the valve.  The various modifications show ways of minimizing the effect of temperature change through the valve and mini-mizing the differential of the valve.  One modification provides a temperature responsive charge in the bellows and the mean effective area of the bellows is greater than the mean effective area of the valve orifice to compensate the closing force and reduce the valve differential.

Abstract: LIGHT PEN DETECTION AND TRACKING WITH        AC PLASMA DISPLAY PANEL                               Abstract A light pen detection and tracking scheme for detecting and tracking both "on" and "off" cells with a single cursor voltage waveform in an AC gas discharge display panel.  The special cursor voltage waveform is applied to the panel during the sustain cycle, in either a line-by-line or binary scanning fashion, to momentarily fire both "on" and "off" cells so that they may be detected by the light pen without a loss of the memory state of the cells.  A cross-hair cursor is automatically displayed at the pen position when the search scan is complete.  Since both "on" and "off" cells are detected, the system can respond to pen motion by repeating the search to reacquire the pen, so that no special tracking strategy is needed.

Abstract: AUDIBLE ALARM FOOD THERMOMETER          Abstract of the Disclosure A portable food thermometer affording an audible alarm at a preset  cooking completion temperature.  A water reservoir defined within a two-part housing is fillable by the user in advance of use.  An elongated sensing probe insertable in the food is secur-ed extending through one of the housing parts inward of the reser-voir and contains a slideable rod supported on a confined temp-erature sensing material.  Expansion of the sensing material in response to increasing food temperature forces the rod outward of the probe.  Opposite the free end of the rod is a spring loaded ball valve sealing the reservoir from a whistle outlet.          Temperature graduations on the housing enable adjusting the spacing between the rod and valve at room temperature for pre-setting the operating temperature of the unit.  On reaching set point cooking temperature, the outwardly forced position of the rod acts to open the valve enabling steam in the reservoir to activate the whistle alarm.  When the alarm is activated, a plug positioned in the whistle outlet is displaced outwardly for affording a visual indication of thermometer operation.   1a

Abstract: ABSTRACT     A material separator includes a housing defining a settling chamber, a communicating drain chamber and a discharge chamber.  A horizontal screw con-veyor extends through the settling chamber and drain chamber to the discharge chamber.  Material to be separated is introduced into the housing at the top of the settling chamber and water is introduced into the bottom of the settling chamber at a flow rate sufficient to partially immerse the conveyor.  The heavier material components sink to the bottom of the settling chamber while the desired lighter components float and are advanced by the conveyor and water flow into the drain chamber.  In the drain chamber, the horizontal screw conveyor is tapered inwardly as the screw conveyor traverses the discharge chamber and a tapered screen is positioned around the tapered screw conveyor to rotate therewith.  This arrangement of the tapered screw conveyor and rotating tapered screen permits an improved separation of the water and fines from the desired stock which is then passed into the discharge chamber.

Abstract: THICK STOCK PUMP              ABSTRACT OF THE DISCLOSURE           A pump for pumping high consistency materials such as paper pulp having a consistency of about 8% or more.  The pump includes a pair of rotors disposed in a pumping chamber, and a number of blades extending radially from each rotor, each blade mounted for cooperation with a circumferential portion of the other rotor in sequence during rotation of the rotors in operation.  The blades are suitably constructed so that during normal pumping of high consistency material they can produce a head of about 10-170 ft., remaining rigid during normal pumping.          However, the blades will flex out of engagement with tramp metal or the like when encountered thereby so that no damage to the pump components results during normal operation.  A relatively large clearance can be provided between each blade and its cooperating circumferential portion of the opposite rotor.  The pump is especially utilizable in pulp treatment systems between vessels adapted to have high density cellulosic pulp there-between.
