Abstract: ABSTRACT      BREATHABLE, NON-POROUS POLYURETHANE FILM     Clothing weatherproofed by being coated with plastics material of low permeability to water vapour is uncomfortable to wear.     The present invention provides a breathable polyurethane film for coating on fabrics to make them waterproof.  The film comprises a hard segment formed by reaction of a low molecular weight difunctional compound with excess diisocyanate to form a prepolymer and a soft segment provided by polyethylene glycol with which the prepolymer is reacted in a stoichiometric amount.  If desired the film can be formed by reacting the polyethylene glycol with excess diisocyanate to form a prepolymer which is then reacted with a stoichio-metric amount of a low molecular weight difunctional compound.  The mechanical properties of the film can be improved by cross linking with a cross linking agent such as a triisocyanate.

The pulley has an optimum pitch radius for its belt teeth addendum circle which has a size between the limits of a maximum pitch radius determined by the radius of a circle through the points of a regular polygon having N equal sides and a minimum pitch radius determined by the radius of a circle having N arcs each equal in arcuate length to the length of each side of said polygon.  During operation with a cooperating belt, the actual path of travel of the belt tooth is thus provided upon entry and exit free of belt motion changing forces caused by the pulley. A close belt tooth to pulley groove fit is provided, and belt flank to tooth flank contact is provided without relative sliding motion therebetween.

Abstract: ABSTRACT OF THE DISCLOSURE      A method of assembling sections of an earth boring bit  for  welding  has  features  to  assure  precise  bit geometry.  The method includes a step of providing a hole in each bit section at the centerline of the 120 degree faces  on  the  interiors  of  the  sections.   A triad  is constructed for use in assembly and consists of three pins joined  together  on  one  end,  each  having  an  axis  120 degrees apart from the other axes of the pins.  The triad is positioned in the holes in the 120 degree faces when the three sections of the bit are brought together.  The shank ends of the sections have holes for receiving dowels located in the welding fixture.   Once the sections are positioned and pinned against movement at the shank ends and at the triad, the sections are clamped, then welded.

Abstract: ROUE DESTINEE A COOPERER AVEC UN FLUIDE L'invention concerne une roue destinée à coopérer avec un fluide et comprenant des organes en forme d'aile (2) agencés autour d'un arbre central (1) généralement orienté perpendiculairement à la direction du déplacement relatif du fluide (5). Les ailes sont articulées suivant des axes de pivotement (3) parallèles à l'arbre central et leur orientation lors de la rotation autour de l'arbre central est déterminée par un mécanisme de commande (6,7,10,11 et 16) réalisé de façon que, dans chaque position angulaire de la roue, les plans (12) dressés suivant les axes de pivotement des ailes et perpendiculairement aux plans principaux de ces dernières se coupent sensiblement suivant une même droite (13) située à l'extérieur du cylindre trajectoire des axes des ailes (4). Le mécanisme de commande comporte, à cet effet, une pièce annulaire (6) d'axe de rotation (8) parallèle mais distinct de celui de l'arbre central (1) et des pièces de réglage (10) coulissant sur des tiges (9) montées tangentiellement à la pièce annulaire (6). Les pièces de réglage (10) coopèrent avec des glissières (11) solidaires des ailes (2) et sont déplacées simultanément dans des directions tangentielles par rapport à la pièce annulaire (6) au moyen d'une bague (16) de réglage. Cette dernière est commandée par un régulateur centrifuge non représenté. La vitesse de rotation de la roue peut ainsi être maintenue constante évitant les nombreuses pannes dues à l'emballement accidentel de la roue. (Figures 1a er 1b)

The ratio of the impedances of the resonant circuits determines the frequency response of the filter. The resonant circuits are isolated from one another by the transistor so that they can be individually tuned.  The presence of the transistor also enables the input return loss of the filter to be determined independently of the tuning of the resonant circuits.  Individual filter stages can be cascaded.     - i -

Abstract: SWAGING APPARATUS FOR RADIALLY EXPANDING TUBES TO FORM JOINTS         ABSTRACT OF THE DISCLOSURE     A swaging apparatus for expanding a tube radially to form a joint, the apparatus including a mandrel for insertion in the tube.   A working fluid is supplied through the mandrel to apply hydraulic pressure to the tube.  The mandrel carries a pair of oppositely direct-ed ramps, and a pair of seal combinations that are movable axially along the ramps.  The seal combinations define the ends of an annular volume within which the pressurized fluid  flows  between the mandrel and the tube, each seal combination including a softer primary seal, which may be an O-ring, and a harder backup seal. Positioning sleeves that are axially slidable on the mandrel prevent angular movement of the backup seals relative to the longitudinal axis of the mandrel, thereby maintaining a uniform circumferential extrusion gap between the mandrel and the tube when pressure is applied.  When the mandrel is being inserted, the seals are disposed at the smaller ends of the ramps so as to minimize frictional resistance to the insertion,  the outer primary seal being resiliently urged inwardly by the corresponding positioning sleeve.   The seals are returned to the large ends of the ramps by the applica-tion of the hydraulic pressure.
