Abstract: FITTING SYSTEM FOR A SPORT SHOE                  ABSTRACT OF THE DISCLOSURE A sport shoe such as a ski boot which has a rela-tively rigid lower shell and a cuff defined by overlapping flaps that can be drawn together over the wearer's lower leg.  Inside the boot is a movable foot bed, the aft end of which is connected to a cable that is routed through open-ings in the boot and over guide about the exterior of the flaps to a buckle.  By closing the buckle, the foot bed is raised and presses the foot against the boot for a uniform fit and, simultaneously therewith, the cuff flaps are tightened over the leg.  The cable is routed and arranged so that in response to a relative forward movement of the cuff, the fit established by the foot bed and the flaps is tempor-arily tightened until the cuff returns to its normal posi-tion.  A strap can be mounted interiorly of the boot so that it engages the instep of the foot when the movable foot bed is raised.

Abstract: Abstract of the Disclosure Polymer blends capable of forming hydrogels upon immersion in water are bonded by heat and pressure alone to water-resistant polymer compositions compatible with vinyl lactam polymers to form laminates. Bo ding can also be achieved by casting on the surface of the polymer composition a solution of the blend in a solvent inert to the polymer composition and evaporating the solvent.  The blends are optically clear blends of vinyl lactam polymers or co-polymers with water insoluble copolymers of a hydrophobic water-insoluble ethylenically unsaturated monomer, an ethylenically asaturated monomer contain-ing an acid group, and optionally a hydrophilic ethylenically unsaturated monomer free from acidic groups.  The laminate of polymer blend in water-resistant polymer composition is particularly suitable for the manufacture of articles which come into contact with body tissues and fluids such as oxygenera-tor membranes, artificial kidney membranes, catheters, shunts or tubing and contact lenses.  The laminate has an improved bond strength between its components.

Abstract: Shot Peening Apparatus Abstract In apparatus for shot peening, gravity is used to accelerate uniform sized steel shot, and thereby impart a combination of good surface finish and uniform com-pressive stresses to workpieces.  It is especially use-ful for finishing gas turbine airfoils.  Shot is intro-duced into the peening enclosure (28) through a gate (40) at near zero velocity.  It is then accelerated along a streamline (31) toward the workpiece (18) with uniform velocity.  The workpiece, positioned along the streamline, can be manipulated in three rotational modes:  oscillatory rotation to uniformly peen con-toured surfaces of a workpiece, periodic incremental rotation to peen different sides of a workpiece; and, tilting motion to enable peening of shoulders (22). The apparatus is especially suited to peening fragile workpieces such as gas turbine airfoils (18).  A di-verter plate (44) intercepts the shot stream at times when repositioning of a fragile workpiece is under-taken.  Thus, possibly damaging impacts are avoided and steady state operation is able to be promptly resumed.

Abstract: "Microorganism Identification Technique"            Abstract A method for the identification of micro-organisms comprises adding to a sample containing an un-known micro-organism an emissive agent such as a radio-active amino acid to produce a mix of emissive products that depends on the metabolic mechanism of the micro-organism.  After incubation, the reaction is arrested and the emissive products are separated, as by electro-phoresis on a gel plate.  The plate may then be autora-diographed by exposure to a photographic film to produce on the latter a characteristic band pattern functioning as an identifier for the micro-organism.  Identification can be effected by comparing the identifier for the unknown with a collection of identifiers for known micro-organisms to find a match with one of these known identifiers.  The comparison may be carried out by scanning the unknown identifier to produce a signal which is compared with signals representing known identifiers stored in a computer.  Alternatively, the emissive products, after separation, may be detected by direct scanning to provide an identifier signal for computer processing.
