Abstract: Hydrogen is produced from water by first reacting I.sub.2, SO.sub.2 and H.sub.2 O to make hydrogen iodide and sulfuric acid. A substantial molar excess of SO.sub.2 and I.sub.2 in the reaction zone creates a lighter sulfuric acid-bearing phase and a heavier polyiodic-acid-bearing phase. The heavier phase is separated, degassed and then contacted with phosphoric acid to permit distillation of HI of low water content and recovery of I.sub.2 as a separate fraction. Hydrogen is recovered from HI vapor, as by thermal decomposition.

Abstract: A method and apparatus employing the method are disclosed for attaching a plastic cover to a safety belt retractor frame. A plastic cover having a pair of spaced legs is attached to a seat belt retractor frame by inserting the legs through an opening in the retractor frame and wedging a plastic plug between the legs to hold them tightly in the opening and restrict withdrawal from the opening.

Abstract: An intravenous and intra arterial delivery system is described having a disposable cassette actuated by a pump and control electronics for providing positive but variable delivery rates. The cassette is self-priming and provides protection against the delivery of air by being unable to impel air, and means provide an indication of excessive air in the cassette. The electronics has low power consumption so as to be suitable for battery operation, such as by way of rechargeable batteries. A pressure sensor in the delivery line may be used to sense infiltration. The system further features a provision for predetermining the amount of fluid to be delivered, and a detection system for detecting an empty supply bottle.

Abstract: A post construction is disclosed wherein an upper post section has its lower portion disposed in overlapped relation with the upper end portion of a lower post section and is connected thereto through a pair of breakaway elements which facilitate breakaway movement of the upper post section relative to the lower post section when the upper section is subjected to a predetermined impact force such as from a motor vehicle. A retainer bar is connected to the upper and lower post sections in a manner to prevent complete release of the post sections from each other upon impact, the retainer bar having lost motion connection with at least one of the post sections in a manner to substantially dissipate the impact force. In a preferred embodiment, the retainer bar is formed with offset web contact portions adapted to engage the opposed webs of the superimposed post sections and establish solid interconnection therebetween.

Abstract: A process for providing gamma globulin with improved intravenous compatibility. In the process, gamma globulin precipitated from blood or blood products is dissolved in an aqueous solution containing a hydrocolloid. The hydrocolloid is capable of forming a lyophilic sol. Gamma globulin is then precipitated from the solution to provide gamma globulin having improved intravenous compatibility.

The description includes a method of making this laminate.

Abstract: Steel strip is continuously roll-formed into tubular shape, seam-welded and coated with zinc in a galvanizing bath. The coated tubing is promptly cooled by a prequench flow of cooling water flowing in the direction of movement of the tubing, thus superficially hardening the zinc. Water is pumped into the prequench zone through passageways arranged radial to the tubing and at an angle between 20.degree. and 40.degree. to the direction of movement. Final cooling is effected by immersion in a water bath. Heavier and smoother zinc coatings can be applied as a result.

Abstract: Methods and apparatus relating to systems for determination of sulfide species and hydrogen sulfide hazard potential of well drilling mud.

Abstract: A retractor is provided with a tension relieving mechanism which is operated by a belt sensor for sensing a taut or slack condition of the belt. The belt sensor operates a blocking means between a blocking position in which the tension of the winding spring is relieved from the protracted belt on the passenger's shoulder and a release position in which the spring winding force is applied to the belt to rewind the belt. Preferably, a cam means is provided to hold the blocking means in its release position to rewind slack occasioned during slight forward protraction movements of the passenger when the belt has been initially set in the tension relieving state. In the preferred embodiment of the invention, the tension relieving mechanism is set into the tensionless condition immediately upon buckling of the belt tongue plate to a buckle. The amount of slack in the protracted belt cannot be increased by ratcheting past the teeth as with prior art tension relieving mechanisms.

Abstract: A method for casting an insoluble anode for use in the electrowinning of copper, the anode being formed by casting molten lead alloy preferably including calcium as an alloying agent in a suitable mold necessary flow of the molten alloy being minimized within the mold, the temperature of the molten alloy and the temperature of the mold being selected to minimize the time necessary for solidification of the molten alloy within the mold, the lead alloy anode preferably being removed from the mold substantially as soon as it is mechanically self-supporting and rapidly cooling the anode in an unstressed configuration to freeze its grain structure and develop dimensional stability. The present invention also relates to a lead alloy casting produced by the above method as well as to an insoluble anode formed from a lead alloy including calcium as an alloying agent, the anode being characterized by the uniform precipitate distribution illustrated in FIG. 7 and the surface finish illustrated in FIG. 9.

Abstract: Apparatus for testing the print through quality of a forms set. The apparatus comprises a horizontal base plate which is adapted to have the forms set laid thereupon. Sleeve means is mounted above the base plate for guiding a hammer for vertical movement to and from a position where its face strikes the forms set disposed on the base plate. Means are provided for releasably locking the hammer at a preselected one of a plurality of heights above the forms set. A raised test sign is provided on either the face of the hammer or on the upper surface of the base plate below the face of the hammer.

Abstract: A closure for glass containers is formed with a top end wall and a depending annular skirt wall. A base ring depends downwardly from the top end wall and supports a small sealing fin which projects downwardly from base ring to engage the finish of a glass container neck in sealing relation when the closure is applied to the container. The preferred base ring is tapered downwardly and outwardly and facilitates the flow of plastic into the sealing fin during molding of the closure. The closure is threaded onto the container neck and the sealing fin comes into contact with the finish. The application of additional closure torque causes the sealing fin to deform and be crushed. Polypropylene has the desired structural properties of flexural stiffness, hardness and compressive strength to be used for the closure.

Abstract: A heat-insulating panel is made by disposing a metal supporting member adjacent a felting screen to lay down a wet refractory fiber mat from an aqueous, refractory fiber-colloidal silica mixture about the metal member.

Abstract: A controller is disclosed for use in controlling environmental conditioning apparatus such as heating and air conditioning equipment in a building or the like. The controller is flexible in that it can control most types of such control devices and apparatus and it eliminates the necessity of a conventional local controller while permitting the use of a centrally controlled automated system if such is desired. The controller is self-contained in that it preferably has a display and keyboard for establishing and changing the operational limits of the apparatus that is to be controlled. Only one sensing device is needed for each apparatus that is controlled, since the signals that are generated by the sensing devices are compatible with the controller as well as with a central automated system if such is used. The controller eliminates the need for a conventional local controller for each apparatus and permits one controller to be used in conjunction with a plurality or a group of control devices.
