Abstract: IMPROVED BLOOD-TAKING DEVICE                 ABSTRACT OF THE DISCLOSURE           An improved blood-taking device of the type wherein a hypodermic needle is inserted into a blood vessel and one or more evacuated containers in succession are connected to the needle for collecting blood samples has two valves therein.  The first valve closes the proximal end of the needle section when a con-tainer is not connected thereto, and the second valve makes it possible to control the difference of pressure utilized for drawing blood from a subject.  The second valve can be closed rapidly in the event it is discovered that the needle lies in tissue exterior to a blood vessel rather than in a blood vessel itself, thereby preventing extravasation and hematoma.

Abstract: ABSTRACT:           The invention relates to a charge-coupled device in which the charge transport in the form of majority charge carriers takes place mainly via the bulk of a semiconductor layer of one conductivity type.        The semiconductor layer has zones of the second conduct-ivity type which do not have an electric contact but which are electrically biased by means of the isolation zone surrounding the semiconductor layer which can be connected to the zones by induction by means of the electrodes and forms a drain for charge carriers from the zones. In an embodiment the device is formed by a two-phase charge-coupled device in which the zones serve to obtain asymmetry in the system. In another embodiment the device is a series-parallel-series multiplex CTD in which the zones form isolation zones between the parallel lines.

Abstract: ABSTRACT OF THE DISCLOSURE         Electrical erosion of refractory in a tank of a furnace for melting thermoplastic materials is reduced by orienting electrodes employed in Joule effect heating of the thermoplastic to limit the current density in the refractory.  High electrical resistivity of certain thermoplastics tends to cause a flow of shunted current in relatively low electrical resistivity refrac-tory of the  furnace walls during Joule effect heating.  Inter electrode spacing and electrode to furnace wall spacing is arranged according to the relative electrical parameters of the furnace system to achieve sufficient Joule effect heating of the thermoplastic without appreciable electrical corrosion.  The effects of three phase power sources with various connections is disclosed.

Abstract: S P E C I F I C A T I O N      METHOD OF CREATING AN OUTDOOR ICE SLAB IN SUMMER WEATHER AND OF  REDUCING ENERGY REQUIREMENTS FOR INDOOR AND OUTDOOR ICE RINKS                       ABSTRACT      Heretofore it has been completely impractical to try to create and hold ice for the purposes of ice skating, curl-ing or sliding during summer weather unless the area were com-pletely enclosed.  This invention presents a method for doing this which is practical not only by keeping refrigeration re-quirements low but also by eliminating dripping, fogging and surface melting.  This method also has the advantage of reduc-ing energy requirements for holding an ice slab under indoor or outdoor conditions.  The method includes creating a floor for ice under which tubes or pipes containing an antifreeze so-lution are laid, connecting a refrigeration plant to chill and recirculate the antifreeze solution, suspending a surface of aluminum foil facing downward covering the entire ice floor at least ten feet above such floor, mounting fans to recirculate the air from below such aluminum surface to above it, freezing ice by applying water upon the floor, painting the ice white to reflect radiant energy, freezing more ice above the white paint, erecting a solid perimeter fence around the ice floor, blowing air through a header box alongside the rink to de-humidify the air and delivering that air through openings in the perimeter fence onto the ice floor area and certain com-binations of the above steps.  The low emissivity of the aluminum foil and the high reflectivity of the white paint prevent radiant energy from loading the ice while recircu-lation fans warm the cool moisture laden and often foggy air over the ice by conveying it to the warm area above the sus-pended ceiling.

Abstract: DEFLECTION COMPENSATING ROLL ABSTRACT OF THE INVENTION         A deflection compensating roll is disclosed which com-prises a support beam, a roll shell rotatably mounted about and defining with said beam an intermediate space therebetween and at least one hydrostatic support element engaged between the beam and the shell for exerting a force against the interior of the shell.  The surface of the support element facing the interior of the shell is provided with a plurality of recesses which are sup-plied with fluid so that a hydrostatic fluid cushion is formed between the face of the support element and the interior of the roll shell.  The beam has a longitudinally extending chamber and means for sealing a first region of the chamber which communicate with the fluid receiving recesses from a second region of the chamber which communicates with the intermediate space between the beam and the shell.  The first and second regions of the chamber respectively define a conduit for supplying fluid to the support element and a conduit for discharging fluid flowing into the intermediate space from the recesses.  The sealing means may in-clude a tubular member disposed in the chamber with the end por-tions thereof being in fluid-tight engagement with the wall of the chamber.  In this arrangement, the annular space between the outer surface of the tubular member and the wall of the chamber communicates with the intermediate space between the beam and the shell and serves as the conduit for discharge of the fluid, while the interior of the tube communicates with the recesses in the sup-port element and serves as the conduit for supplying fluid there-to.  A device such as a scoop ring disposed in the intermediate space may be provided for feeding fluid from the intermediate space to the annular space between the tubular member and the wall of the chamber.

Title: High drain rate, primary alkaline cell having a divalent silver oxide/monovalent silver oxide depolarizer blend coated with a layer of silver

Abstract: ABSTRACT OF THE DISCLOSURE A high drain rate, primary alkaline cell comprising a negative electrode, a divalent silver oxide (AgO)/monovalent silver oxide (Ag2O) depo-larizer blend, a separator between said negative electrode and depolarizer blend, and an alkaline electrolyte consisting essentially of potassium hydro-xide.  The surface of the depolarizer blend adjacent to the separator is coated with a layer of silver.  The reduced surface layer of the depolarizer provides improved stability of the depolarizer blend in the alkaline electrolyte, and it provides the cell with a single voltage plateau during discharge.  The cell is characterized by a maximum open circuit voltage of about 1.75 volts.  The surface of the depolarizer blend can be reduced to form the silver layer ei-ther prior to being placed in the cell container or after the blend is consoli-dated in the container.  The amount of divalent silver oxide present in the depolarizer blend is critical, and the blend may contain up to about 70% by weight of divalent silver oxide and still achieve a single voltage plateau during discharge.  The cell has a high drain rate capability whereby is can be pulsed, said cell being capable of providing a flash amperage greater than an average of 0.20 amperes per square centimeter of cell cross-sectional area.
