Abstract: IMPROVED SINGLE STROKE DISPENSING APPARATUS            ABSTRACT OF THE DISCLOSURE           A material dispensing apparatus for placing a mate-rial in the uterine cavity and moving the material from the uterine cavity into the Fallopian tubes of a female.  An elon-gated probe carries an expandable member, and a housing con-nected to the probe has a piston and cylinder structure and a container for storing the material.  Material and expansion drive mechanisms are connected to a single actuator selectively controllable by an operator.  When the actuator is operated it is moved into the housing to both dispense the material and expand the expandable member.  Pressure control means are provided in the drive linkage for expanding the expandable member to assure that a predetermined maximum pressure is not surpassed.  The operator may fully depress the actuator and the pressure control means will both determine the maximum pressure and substantially maintain that pressure should a leak occur.  Additional pressure control means are provided in the cylinder structure to compensate for atmospheric pres-sure change and to coordinate the balloon expansion relative to the material dispensing.  Means are also provided in the material dispensing drive linkage to prevent the dispensed material from flowing back into its container when maximum pressure is applied.  A replaceable probe portion is provid-ed in the preferred embodiment.

Abstract: Abstract of the Disclosure A catalytic reactor useful for carrying out a catalytic reaction wherein gaseous or vaporized reactants are flowed into contact with a mass of particle-form catalytic material comprises a horizontally disposed reaction zone, foraminous retaining means disposed within said reaction zone transversely thereto and occupying the complete cross-section of said reaction zone available for the flow of gaseous or vaporized reactants therethrough form one end to the other end of the reaction zone, the foraminous retaining means defining a transverse volume or space within the reaction zone along a portion of length thereof, said transverse volume or space adapted to be filled with particle-form catalytic material, and a chamber disposed at the upper portion and integral with said reaction zone in open communication at the bottom end thereof with said trans-verse volume or space and closed at the upper end thereof, the chamber being adapted to be substantially filled with particle-form catalytic material for maintaining the transverse zone or spaced filled with particle-form catalytic material such that as said gaseous or vaporized reactants flow through the reaction zone the gaseous or vaporized reactants come into contact with said particle-form catalytic material to effect the desired catalytic reaction.  The catalytic reactor is generally useful for carrying out catalytic reactions involv-ing contact between gaseous or vaporized reactants with a mass of particle-form catalytic material and, in one embodi-ment, is particularly useful as a catalytic recombiner for boiling water nuclear reactors wherein condenser off-gases containing steam, radiolytic hydrogen, radiolytic oxygen and other gases are brought into contact with particle-form catalytic material, such as a platinum-group-metal-containing catalyst, e.g. platinum-containing catalyst, so as to effect reaction between the radiolytic hydrogen and radiolytic oxygen to produce steam which is condensed to water and re-covered, thereby substantially reducing the volume of remain-ing gases, such as leakage air and radioactive xenon and radioactive krypton, to be subsequently handled for disposal.

Abstract: PHD. 77-023 8.3.78 ABSTRACT:        The invention enables the density distribution in a plane, in particular in a planar slice of a body, to be reproduced with the aid of scattered radiation.          A narrow X-ray beam is then passed through the body to be examined. The scattered radiation produced in the path of said primary beam through the body reaches an array of detectors through a slot diaphragm which is disposed outside the primary beam, the slot diaphragm and the detectors being arranged so that each detector can only measure a spatially limited part of the scattered radiation originating from the primary beam.          Thus, at the end of a measurement the detector output signals represent a qualitative image of the density distribution inthe body along the primary beam.          Subsequently, the body is moved by approximately the width of the primary beam normal to the direction of said beam, thus enabling line scanning to be realised.

Aluminium sheet is brought into engagement around a multi-strand steel rope. These parts are moved together through a press while the sheet is continuously wrapped around and compressed onto the rope so as to enter the recesses between adjacent strands of the rope.  Subsequently aluminium strands are wound around and along the aluminium sheet, such strands being compressed to become deformed and abut each other tightly and also to deform the outer surface of the aluminium sheet.  The invention provides a construction of improved mechanical strength, smaller cross-section and longer life than former constructions.

Abstract: ABSTRACT OF THE DISCLOSURE           The side-by-side panels of a standing T-rib roof can be provided in any necessary lengths due to a smooth telescopically interfitting arrangement lengthwise between adjacent panel sections. One end portion of each panel section is tapered without cutting or crimping the metal thereof and when slipped endwise into the untapered end portion of another panel section forms a smooth slip joint of uniform cross sectional dimensions relation to the complete assembled panel.  An improved clip for attaching roof panels to underlying purlins features a vertical stand-off space between the clip attaching feet and lateral panel support branches thereabove so that a thermal insulation blanket can be placed in the stand-off space.  This vertical stand-off space greatly decreases the thermal conductivity of the metal roof and, therefore, increases the thermal value.

Abstract: ABSTRACT OF DISCLOSURE      The risk of lung "squeeze" in use of diving headgear in return-line diving systems arises through the need to subject the exhaust hose to suction pressure in order to withdraw the used gas from the helmet.  The usual exhaust regulating valve can quite readily jam, needs considerable servicing, and can only provide the desired high flow rates at the expense of the mechanical advantage which must how-ever be kept high to avoid rendering the valve unduly sen-sitive to across-the-valve fluctuations.     According to one aspect of the invention, all of these difficulties are met by using on the helmet a novel exhaust regulating valve comprising a collapsible and expansible housing including a hinged flap and a peripheral bellows wall on the flap, an orificed seat in the housing covering an outlet opening in the housing, and a flexible membrane adjacent to the seat and connected to the flap so that hinge-ing movements of the flap in response to pressure variations in the helmet effect progressive laying of the membrane on to and progressive lifting of the membrane from the orificed seat. A further safety feature is a shut-off valve whereof the seating is at an inlet opening in the housing and the closure member is on the hinged flap.     According to another aspect of the invention, superior lung ventilation is obtained by using demand-type supply and exhaust valves, and spring-loading them both to the open position.  It is found that the work of opening one is done by the other and vice versa, rather than by the user of the equipment.
