Abstract: PIVOTALLY MOUNTED SURGICAL INSTRUMENT HOLDER          Abstract of the Disclosure A surgical instrument container has a top and bottom whose opposing surfaces are bordered by sidewalls and articulately connected to form an enclosed box.  A planar substrate having upper and lower surfaces adapted to receive surgical instruments is pivotally mounted between the top and bottom.  When the box is open, the substrate can be pivoted between the top and bottom to provide easy access to both upper and lower substrate surfaces.  The substrate is positioned within the sidewalls of the top and bottom surfaces to effect enclosure of the substrate when the box is closed and thereby prevent retained surgical instruments from protruding through or falling out of the box.  The substrate may be a porous foam or magnetic material or combination of each.  The box may be mechanically or magnetically latched.  The box may be composed of transparent material to permit visual inspection of the retained instruments when the box is closed.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention is directed to a solid aromatic copolyestercarbonate containing meta-phenylene groups and para-phenylene groups wherein the molar ratio of para-phenylene to meta-phenylene is from 19:1 to 1:19. The copolyestercarbonate contains ordered repeating units of the formula:          wherein each R is independently an aromatic hydro-carbylene or inertly substituted hydrocarbylene, x is a number from 0.05 to 10, R1 is a mixture of meta--phenylene or inertly substituted meta-phenylene and para-phenylene or inertly substituted para-phenylene. These copolyestercarbonates exhibit physical properties such as heat resistance, clarity and impact strength that are superior to the comparable properties of corresponding random copolymers.  They exhibit melt processability that is superior to the melt process-ability of corresponding copolyestercarbonates wherein 28,910-F     R1 is entirely para-phenylene.  They exhibit heat resistance, notch sensitivity and low temperature impact resistance that are superior to corresponding copolyestercarbonates wherein R1 is entirely meta--phenylene.

Abstract: Abstract of the Disclosure The invention provides a heat pump system employing a refrigerant charged space and including at least two evaporators, one of which is an ambient air head absorber, and the other of which can be of the same type, or of the type  obtaining heat from solar insolation, water, ground heat, etc.  The coil or coils of an ambient air absorber must be defrosted periodically.  In the system of the invention defrost heat is applied to the evaporator coil or coils while the compressor is operating, such defrost heat causing vaporisation of the refrig-erant therein.  The system includes a pressure containment valve between the evaporator and the compressor that maintains the vapour pressure of the vaporising liquid in the coil above the value at which the ice will readily melt, the valve releasing excess vapour to the compressor and thence to the condenser which discharges the heat to the space to be heated.  Thus, the only part of the defrost heat lost from the system is that required to melt the ice.          Preferably the evaporator is an ambient air unit paralleled by one or more solar heat absorber evaporators which do not require defrost-ing, so that the compressor can work efficiently and continuously with the refrigerant from the solar absorber.  The system may include heat exchangers enabling the heat obtained to be used for different purposes.  The system also works on a cooling cycle when required by suitable change over valve means.

Abstract: Abstract A flowmeter in which a bladed rotor element is mounted in bore formed in a body so that the element rotates at a speed representative of the rate of flow of a fluid along the bore. Electromagnetic radiation is directed from a source into the bore and a radially outer face of each blade on the rotor element moves across the path of the radiation once during each rotation of the element.  Radiation reflected by the outer faces of the blades is directed to a photosensitive detector.  Direction of radiation towards the element and direction of reflected radiation towards the detector is effected by means which comprise at least one elongated guide member having a refractive index greater than the refractive index of the medium in which the member is disposed. The or each guide member is preferably formed integrally with the body in which the bore is formed.

Abstract: ABSTRACT OF DISCLOSURE      An improved bias generator provides a bias voltage output which is a function of an input current Iprog and provides a bias current to a preselected load which tracks the input signal independently of temperature. The amount the bias voltage output changes with tem-perature is determined by (1) V(T, Iprog), a voltage-current temperature dependent function of the base-emitter voltage drop of at least one transistor and (2) X, a scalar which is easily provided by setting the ratio of two resistors.  The generator can there fore be easily constructed for particular circuit loads which include at least one semiconductive junction such that the biasing current through the load will be substantially independent of temperature.

This drain has a uniform cross-sectional area and is preferably made from a silicone elastomer having a durometer shore between 40 and 70 shore A.  Such uniform cross-sectional area provides added strength to prevent the drain from breaking during its removal from the patient's body, and the silicone elastomer provides sufficient elasticity to permit the cross-sectional area of the drain to decrease by at least 30 percent when a pulling force is applied thereto, thereby reducing the gripping force of tissue surrounding the wound.

Abstract: ARCTIC BARGE DRILLING UNIT                         Abstract An  improved  marine  drilling  barge  for  use  in ice-covered water  is  disclosed.   The  barge  has,  besides  a conventional  moon  pool  through  which  conventional  marine drilling operations can proceed, a roughly circular polygonal hull plane with an elevation of two truncated pyramid sections joined through their theoretical  apices by a vertical walled matching polygonal section.  The flat bottom of the hull, to or through which mooring lines are attached to anchor the barge, has an exterior guard member fastened thereto and surrounding the points at which the mooring lines attach or come closest to the hull.  The barge is ballasted to achieve downward breaking action by the hull on the ice cover as the latter encroaches on the barge.  The proportions of the hull combine with those of the guard member to ensure that the ice broken from the ice cover is deflected to avoid fouling the mooring lines while the maximum draft of the barge is no greater than 20 metres.
