Abstract: LIMITED BEND MALLEABLE PENILE PROSTHESIS               ABSTRACT OF THE DISCLOSURE         A prosthesis adapted to be implanted in a penis includes an elongate malleable element which may be bent to enable the prosthesis to be conformed to a variety of shapes.  A bend-limiting member is positioned next to the malleable element and serves to limit the radius of bend of the malleable element and thereby minimize damage or weakening to the malleable element through extreme bending.  The malleable element and the bend-limiting member are encased within a physiologically inert plastic body.

Abstract: Abstract A supported transition metal composition is obtained by suspending a support material in an inert liquid medium, spraying the suspension, collecting a solid material and contacting the sprayed solid with a transition metal compound. The support material may be a metal halide such as magnesium chloride or an inorganic oxide such as silica or alumina. In addition to being contacted with the transition metal compound, the support material may be contacted either before or after the spraying step with other reagents such as oregano metallic compounds, halogen compounds, or Lewis Base compounds. The product obtained after contacting with the transition metal compound may be used as a component of a polymerisation catalyst system to polymerise an unsaturated monomer such as ethylene or propylene.

Abstract: ABSTRACT OF THE DISCLOSURE     The use of certain prepolymers of 4,4'-methylenebis-(phenyl isocyanate), in place of the latter diisocyanate itself in the preparation of polyurethane-polyureas using aromatic diamine extenders, has a number of advantages particularly when the compositions are prepared by reaction injection molding techniques using two streams of reactants.  The principal advantages are (i)  a useful increase in gel time and (ii) a ratio of amounts of the two reactant streams which more nearly approaches 1 : 1 .     This latter factor not only improves the efficiency of mixing of the components in the mixing head but, together with the longer gel time, significantly increases the output of mixed reactants per unit of time.  The prepolymers of 4,4'-methylenebis(phenyl isocyanate) employed to achieve the above results are those derived from polyoxy-ethylene polyoxypropylene polyether diols and triols (MW = 1000-10,000), polytetramethylene glycols (MW = 600-5,000) and polyester diols and triols (MW = 500-8,000).

Title: Ski binding

Abstract: IMPROVED SKI BINDING              ABSTRACT OF THE DISCLOSURE         A ski binding of the type usable with a ski boot having projections extending laterally from the sides of the boot.  Typical projections are those on the side margins of an oversized plate secured to the bottom of the boot.  The binding has a pair of spaced jaws which are adapted to be placed near the sides of the ski and to be moved laterally into overhanging relationship to the side projections on the ski boot when the ski boot is on the binding.  A jaw release mechanism having a pivotal, spring biased lever causes the jaws to move toward and away from each other as a function of the pivotal movement of the lever in opposite directions relative to the ski.  An adjustment member on the binding determines the amount of overhang of the jaws above the side margins of the side projections on the ski boot.  The amount of overhang of the jaws determines the force required to open the jaws against the spring bias force of the jaw release mechanism.  The adjustment member has a central, tubular element which projects upwardly from the binding and is depressed by the ski boot placed on the binding.  A compression spring in the tubular element biases the adjustment member upwardly.  The ends of the adjustment member have spaced teeth for intermeshing with respective teeth on respective jaws to releasably interconnect the adjustment member at a given height above the ski as a function of the weight of the skier using the binding.  For skiers of medium weight, the jaws overhang the side projections of the ski boot by a medium amount.  For a heavy weight skier, a maximum amount of overhang of the jaws is provided above the side projections of the ski boot.

Abstract: SNAP-TOGETHER HOUSING            Abstract A snap-together housing is disclosed having a single fastener holding the multi-part housing together. The housing has a base, around which upper and lower panels fit in a clamshell arrangement.  The wrap-around panels provide design contours and are the color bearing elements of the housing.  Easy installation is achieved by a tab positioned at the rear of the lower panel which allows the lower panel to rotate upward around the base.  A tab on the inner front surface of the lower panel engages a detent on the front of the base thereby preventing the lower panel from rotating downward without first being laterally separated from the base.  The upper panel, held in position by a single fastener, interlocks with the front surface of the lower panel to prevent the lateral separation.

Abstract: ABSTRACT A subscription television system includes a head-end for transmitting selected fields of a television signal in a scrambled form, the scrambled fields being identified by an encrypted mode control code inserted in a selected horizontal line of the preceding vertical interval. The mode control code is formed such that a predetermined non-transmitted control code is realized when the mode control code is processed with vertical interval system control data according to a selected function. A decoder processes the received mode control code and system control data according to the selected function to reconstitute the predetermined control code for enabling unscrambling of the following field. The decoder may employ majority voting techniques whereby not all of the bits of the reconstituted control code need be properly recovered to enable the unscrambling function.
