Abstract: UNIVERSAL PIERCING PIN          Abstract of the Disclosure A universal piercing pin for vented and unvented I.V. administration sets has a hollow spike member with fluid passages spaced apart around the external surface of the spike member.  In vented sets, the tip of the spike member and an entry port to a fluid passage are inserted sufficiently through the seal of a rigid solution container to allow fluid to pass out of the container through the spike member and air to pass into the container through the fluid passage.  A hydrophobic filter, positioned in a fluid passage, prevents the passage of liquid but allows the passage of air into the container.  In unvented sets, only a portion of the spike member is inserted through the seal of a flexible I.V. container which allows fluid to pass out of the flexible container through the spike member without allowing air to flow into the flexible container through the fluid passages.

Abstract: REMOTELY RELEASABLE CHOKER ABSTRACT OF THE DISCLOSURE In logging and other handling operations, a cable is often looped about the elongated object and cinched tight through a choker hook assembly in order to transport the objects. A remotely controlled hook assembly has a body, including an eye for the passage of the cable and a releasable latch arm for grasping the end of the cable. Encased within the body is a slidable pin that serves to lock the latch arm and therefore the end of the cable. A positioning means is also within the housing and serves to rotate a catch member allowing the slidable pin to move downwardly, thereby releasing the latch arm and cable. A pair of appropriately sized and located springs serve to both move the sliding pin downwardly and to bias the pin upwardly. A radio controlled servo may be used as the positioning means.

Abstract: Process for the preparation of a very pure commercial form of 4,2',4'-trichloro-2-hydroxydiphenyl ether Abstract A very pure, dust-free commercial form of 4,2',4'-trichloro-2-hydroxydiphenyl ether with little odour is pre-pared by diazotising 4,2',4'-trichloro-2-aminodiphenyl ether, boiling the diazonium salt and purifying the reaction product.  The pure, dust-free and odour-free commercial form is obtained by separating off the acid aqueous phase of the reaction mixture, rendering the mixture containing 4,2',4'-trichloro-2-hydroxydiphenyl ether and 2,4,8-tri-chlorodibenzofuran alkaline, extracting it several times with an inert water-immiscible solvent, either after removal of the organic solvent by steam distillation and precipi-tation of the by-product 2,4,8-trichlorodibenzofuran or directly, and then adjusting the pH to 3 to 10;  subsequently, the highly volatile constituents are removed from the 4,2',4'-trichloro-2-hydroxydiphenyl ether melt which has separated out, the melt is subjected to molecular distil-lation and the distilled melt is introduced into an aqueous dispersion of crystalline 4,2',4'-trichloro-2-hydroxydipheny ether, this dispersion simultaneously being subjected to wet grinding. Filtration and drying gives a granular-like ready-to-use commercial form.

Abstract: ABSTRACT            Continuous production of aluminium hydroxycarbonate gel by continuous reaction of aluminium salt solution with mixed alkaline carbonate and bicarbonate solution under homogeneous conditions in a relatively small reaction vessel, and continuing the reaction in a subsequent reaction vessel under controlled pH.  The product gel is separated from the non-aluminium cation containing reaction mixture within less than about 6 hours, whereby formation of poorly soluble addition reaction products such as dihydroxy aluminium sodium carbonate, which contribute undesired non-aluminium cations to the gel product, is reduced.  The aluminium salt solution is adjusted in pH by adding to it a portion of the mixed carbonate and bicarbonate solution to obtain a clear solution of pH 3.5 to 4Ø  This results in a smooth, creamy gel with less objectionable chalky mouth feel.

Abstract: TITLE:  SINGLE VERTICAL MOTION FEEDTUBE         PROTECTOR AND ACTUATOR FOR A FOOD PROCESSOR     INVENTOR:  JAMES E. WILLIAMS                 ABSTRACT OF THE DISCLOSURE           Single vertical motion feedtube protector and actuator for a food processor having a feedtube with a food passageway of relatively large cross-sectional area, sometimes called an "expanded" feedtube.   The cover remains secured in its normal operating position on the bowl during loading of food items into the feedtube.   A single vertical downward movement of the protector apparatus onto the feedtube following loading causes the actuating means to depress the movable con-trol rod for rendering the motor drive operable.  Also, the food pusher is aligned with the food passageway for plunger action therein for pushing food items to the rotary tool in the bowl.  Conversely, a single vertical upward movement of the protector apparatus off from the feedtube fully exposes the feed passageway while simultaneously releasing the movable control rod for rendering the motor drive inoperable.  The upper end of the control rod is covered over and protected by a protective cap or cover which is closed over on top.   In one embodiment of the invention, the actuating means in the protector apparatus converts downward or upward motion of the protector apparatus into lateral extension or retraction motion, respectively, of a tongue-shaped cam member for entering into contact with the upper end of the control rod by moving through apertures in the sidewalls of the protective cap for respectively depressing or releasing the control rod.   In another embodiment of the invention a pivoted arm mounted on the cover enters into apertures in the sidewalls of the protective cap when the cover is secured into its operating position by turning the cover on the rim of the bowl for causing this pivoted arm to come into contact with the upper end of the control rod for trans-mission of downward or upward motion of the protector apparatus into depression or release of the control rod.
