Abstract: A method and apparatus for recovering uranium and/or related values which include means for protecting ion-exchange resins in the recovery operation from oxidative degradation due to contact with hydrogen peroxide.  A guard chamber is positioned in the elution circuit so that barren eluant, after it is stripped of its uranium and/or related values by treatment with hydrogen peroxide, will flow through the chamber.  The guard chamber contains catalytic material, e.g. activated carbon, which decomposes hydrogen peroxide upon contact into water and oxygen.  The barren eluant, after it passes through the catalytic material, is used to make up fresh eluant for reuse in the re-covery method without the risk of the fresh eluant causing oxidative degradation of the resins.

Abstract: ABSTRACT           Improved dispensing apparatus for dispensing machines of the type having at least one dispensing tray containing a dispensing unit which dispenses articles from the machine by the use of a helical dispensing coil.  Improved mounting appa-ratus is provided for supporting both the forward and back end portions of the dispensing coil. A cross-bracket member having a portion extending across the diameter of the coil, is mounted to the back portion of the coil.  A cross-bracket holding device, connected for rotation by appropriate motor means, releasably accepts the cross-bracket for mounting the back portion of the coil in elevated position above the shelf surface of the dispensing tray.  The cross-bracket holding device is configured to matingly accept differently sized cross-bracket members, to enable rapid interchangeability of differently sized dispensing coils in the machine. Coil sup-port apparatus mounted to slidably engage the outer circum-ference of the dispensing coil near its forward end supports the forward end of the coil in elevated spaced-apart manner above the tray surface, and supports the coil in a manner which minimizes jamming of the items being dispensed at the forward end of the coil. Coil compression means mounted adjacent the forward end of the dispensing coil causes the coil to positively eject or to impart dispensing motion to the item being dispensed from the convolutions of the coil, during the dispensing rotation movement of the coil.

Abstract: Abstract of the Disclosure Method and apparatus for processing table and bed linen which embodies no-iron fabrics which may be composed in at least a substantial part of polyester fiber, or may be composed of other fibers which have been treated to provide no-iron charac-teristics (linen being used in a generic sense rather than to identify the fiber composition).  The process includes the sequential steps of laundering the linen, preferably in sub-stantially conventional manner, and then folding the laundered linen in a dry state to provide a stack of multiple layers of the laundered textile fabric, all of the layers being of approximately equal area.  The multiple layers of fabric are then finished by compressing the multiple layers in folded state in the presence of heat and moisture, causing steam to flow through the stack of multiple layers, first in one direction and then in the opposite direction.  The flow of steam through the stack of layers is assisted by injecting the steam against the layer at one end of the stack and apply-ing vacuum to the layer at the opposite end of the stack so that the vacuum assists the flow of steam through the entire stack.  Following this operation, the steam and vacuum are reversed, causing the steam to flow in the other direction.      The apparatus of the present invention embodies a pair of platens which are relatively movable to provide for the positioning of the stack of layers of textile fabric between the platens.  Pressure means is provided to apply mechanical pressure to the stack of linens and each platen is hollow and has fluid connections for steam and vacuum.  Each platen is perforated and a mask is provided to adjust the perforated area precisely to the area of the layers of fabric placed between the platens.  Heater means may be provided to maintain each platen above the dew-point temperature of the steam supplied thereto.

Abstract: A B S T R A C T           The invention relates to a catalytic titanium component useful for the polymerization of alkenes-1 and for the copolymerization of alkenes-1 with each other or with ethylene, which titanium component contains a halogenated titanium compound, an electron donor, and a mixture of a magnesium halide and an aluminum halide.           The titanium component according to the invention is charac-terized in that it contains 0.1-10 % by wt. of titanium and the titanium : magnesium : aluminium weight ratio amounts to 1 :(0.5-20) :      (0.05-2.5), while the magnesium : aluminium weight ratio is at least 3 : 1.           With these specific weight ratios, the aluminium halide does not act as an inert filler, but has a very special action, reflected in a particular high activity at good stereospecificity of a catalyst system containing such a titanium component.           The catalytic titanium component according to the invention is mainly of importance for stereospecific polymerization of propylene.

Abstract: ABSTRACT OF THE DISCLOSURE       A device for the sterilization of liquids by means of ultraviolet radiation whereby a low-pressure high-current mercury vapor lamp is used with a discharge tube as the radia-tion source wherein the cooling of the lamp is effected by means of an air flow circulating in the device and adjustment of the mercury vapor pressure by heating the cooled air in a heating device and the heating of a cecum-shaped piece of tubing with this heated air. In order to reduce the energy consumption dur-ing this heating phase, a mechanism is provided in the device in order to lead a first portion of the cooled air flow directly to the discharge tube of the lamp. A second portion of the cooled air flow, which is smaller in comparison with the first portion, is heated by the heating device and led to the cecum.

Abstract: TITLE OF THE INVENTION            PORTABLE PRINTING ELECTRONIC CALCULATOR            ABSTRACT OF THE INVENTION          The calculator is small enough and well protected enough to be carried in the pocket.  In addition to a keyboard, circuit board, batteries and an LCD data display, there is a printer comprising a platen which draws paper from a roll in a compartment. A thermal printing head is reciprocated along the writing line by a pin engaging in an eccentric cam groove in a disc rotated by a crown wheel and a pinion of the shaft of a motor.  Another cam-follower pin reciprocates a slide which advances the platen incrementally after each traverse of the head.  A slidable cover is shown open, exposing the printing mechanism and operating a switch which enables the printer.  Results appear on the LCD display and are printed.  When the cover is slid closed it protects the printing mechanism and disables it via the switch. The calculator can nevertheless be used without the printer, results being displayed only on the LCD display.  The paper roll is carried in a removable container to which access is obtained by depressing a detent tongue and sliding the cover still further open.  Cooperating parts of the container and the calculator frame guide the leading strip of the paper between the platen and the print head.  When the cover is closed it bends a tongue of the container to nip the paper and immobilize it.
