Abstract: MEDICAL INFUSOR                   Abstract of the Disclosure A portable elastomeric bladder-powered infusor for dispensing drug in liquid form under pressure at a predeter-mined flow rate is disclosed.  The main elements of the infusor are a tubular housing, a plug/flow control assembly fixed in one end of the bladder, an axially slidable piston/filling port assembly within the housing, and a tubular bladder.  The plug and piston assemblies each has an axial post about which the bladder ends are attached.  When the bladder is not charged with drug, the posts fill the bladder's lumen and their ends abut.  Drug is charged to the infusor by inserting a drug-filled syringe into the open end of the housing with the syringe's needle entering an axial bore in the piston, penetrating a septum that blocks the bore, and extending into the axial post.  The force exerted on the piston by the syringe is transmitted to the fixed plug assembly via the axial posts.  Drug is plunged from the syringe causing the posts to separate and the bladder to expand axially and radially.  Once the bladder is filled, the syringe is withdrawn, with the septum sealing itself.  The drug is dispensed from the bladder via the plug/ flow control assembly and a conduit that is connected to that assembly and extends to the infusion site.     4:130:11

Abstract: ABSTRACT OF THE INVENTION           ICE SKATE SHARPENER      The invention comprises an improved ice skate grinding, sharpening and contouring machine.  The machine includes novel means to accurately center an ice skate between the heel and sole struts in a movable holding fixture and means to select the best contour position on the blade as a function of intended skate usage.  As an example, the best blade contour for a hockey forward requires a deeper grind below the forward strut than the contour for a hockey defenseman.  The centering feature assures that the skate contour desired will be accurately ground onto the blade and pitched forward the desired amount.  Means to adjust the blade position relative to the blade holding fixture for pitching are disclosed in one embodiment.  In an alternative embodiment means for pitching the entire fixture as desired are disclosed.          Figure skates can be advantageously centered and pitched as desired with the invention for accommodating the particular requirements of the figure skater.         New hockey skates with unconventional molded plastic struts such as the Canadian TUUK 2000 have entered commerce.  Such skates are accommodated by a modified fixture, for positioning the blade center location that is equivalent to the center location of a hockey skate with conventional struts.

Abstract: MODULAR SCREW ANCHOR HAVING LEAD POINT     NON-INTEGRAL WITH HELIX PLATE            Abstract of the Disclosure A high strength, modular screw anchor is disclosed which exhibits enhanced failure resistance notwithstanding use of essentially the same amount of material as conventional anchors, and which can be installed using existing installation equipment.  The preferred screw anchors of the invention include an elongated rod having one or more separate, specialized anchor members supported thereon, and an improved, obliquely oriented, beveled earth-penetrating lead to facilitate installation, particularly in rocky soils.  The anchor member includes a tubular, central, rod-receiving hub presenting a polygonal in cross-section bore therethrough, and an outwardly extending helical blade affixed to and coaxial with the hub.  In installation procedures the anchor rod is passed through the hub bore and the anchor member is operably coupled to the rod (as by resting it atop an outwardly extending shoulder provided on the rod); the tubular shank of a standard anchor wrench is next telescoped over the anchor rod and inserted into the hub bore such that a driving connection is established between the rod, shank and anchor member.  Axial rotation of the wrench thus effects corresponding rotation of the screw anchor for installation purposes.  The earth-penetrating lead of the screw anchor may be formed integrally with the major portion of the rod, or threaded thereon; in the latter case the overall length of the rod can be adjusted as desired.  The (Docket No. 16993) modular nature of the screw anchors hereof permits stocking of only a relatively few standard compo-nents which can be used as needed in the field to achieve a desired anchor configuration.

Abstract: ABSTRACT A PROCESS FOR THE PREPARATION OF HYDROGEN-CONTAINING GASES.        In a process for preparing hydrogen-containing gases, including ammonia synthesis gas, from hydrocarbons by desulfurization, primary and secondary reforming, shift conversion in two steps, removal of CO2 and methanation, the first step of the shift conversion is carried out with a catalyst consisting of copper oxide, zinc oxide and chromium oxide at a steam to dry gas ratio below 0.5, preferably 0.3-0.5, at 10-50 atm. abs. and 190-400°C, preferably 200-360°C; and second step of the shift conversion with a catalyst of copper oxide, zinc oxide and aluminium oxide at an inlet temperature of 160-195°C, preferably 175-195°C, at the same time being at least the highest of the temperatures (T1+ 10)°C and (T2 + 10)°C where T1 is the dew point and T2 the equilibrium temperature for the reaction  .   One avoids the carbide formation occurring when using the conventional iron catalysts in the first step of the shift conversion; and avoids the difficulties encountered with conventional copper-containing low-temperature shift catalysts in the first shift step. At the low temperature in second shift step one obtains a low reaction rate for methanol-formation (which involves a loss of energy), and avoids with the particular catalyst the large amounts of catalyst that is needed in the second shift step of known shift conversions when conventional shift catalysts are used.

Abstract: ABSTRACT OF THE DISCLOSURE           A control valve for maintaining the temperature respectively the viscosity of pressure fluid passing there-through substantially constant comprises a control slide pro-vided with a throttle bore and downstream of the control slide a precontrol valve in which an end portion of an element expandable by the temperature of the pressure fluid is arranged.          When pressure fluid with a certain pressure is fed through the inlet end of the control valve, the control slide is lifted from its seat and the precontrol valve opens.  All of the pres-sure fluid entering the control valve is passed through vari-ous bores and annular gaps along the precontrol valve to the temperature expandable element.  When the fluid reaches the desired maximum temperature a bypass for the fluid is created by the expandable element and a control pin actuated by the latter.  thereby the throttle action of the control valve is reduced and overheating of the pressure fluid avoided.  A throttle gap between the control slide and the housing will assure removal of any air contained in the pressure fluid and a further throttle gap formed between an end face of the con-trol slide and a disc attached thereto serves to catch any foreign particles in the pressure fluid which will be flushed away after moving of the control slide away from its seat.
