Abstract: A hip joint femoral prosthesis has a rod (2), the proximal end (6) of which has a cross-section of oval shape and a surface area increasing towards the proximal end. At least one wall of the proximal end includes alveoli (9) therein hollowed out so as to present a maximum depth on their side towards the proximal end. The alveoli are of a circular or semi-circular shape and intersect, thereby providing a surface which improves the stability and anchoring of the prosthesis into the femur.

Abstract: An apparatus for squaring a sleeve (10) having at least one pair of opposed bevelled corners comprises a cradle (44) having sleeve supporting members merging towards an apex but terminating spaced from the apex and having a support beam (46) in the space between the members and the apex. The support members and support beam are arranged to conform with the outside shape of the sleeve in squared condition. An platen (66,68) is moveable into a sleeve while the sleeve is supported in the cradle. The platen is shaped to substantially conform with the inside of the sleeve in squared condition and is moveable toward the apex to force the sleeve into conformity with the cradle and the support member and thereby square the box. Preferably an end closure pad applicator (78) will apply an end closure pad (26) to the squared sleeve while supported in the cradle and with the platen in place to resist pressure applied to the outside of the sleeve when the pad is being secured to the sleeve.

Abstract: A decorative laminate, and a process for making same, featuring a protective outer layer which provides superior scratch, wear, and chemical resistance, and which is tightly bound to the layer immediately beneath so as to reduce the tendency of the protective layer to delaminate from the layer immediately below. The laminate uses radiation-polymerizable urethane acrylate coated surfaces and utilizes a photoinitiator, a thermal catalyst and a coupling agent. The coupling agent serves to more securely bond the protective layer to the surface onto which the protective surface is coated. The protective layer is created by first applying the reactants to finish paper, then partly curing by UV radiation. The partly cured material is then applied to the surface to be protected, and the laminate is consolidated and the outer layer is completely cured by thermopressing.

Abstract: Skeleton boxes for liquefied gas containers conventionally have a loading opening formed in one side wall of the box and, as a closing device, a metal closure rod which divides the loading opening transversely and is held in metal bushes. However, the use of metal leads to a progressive deformation of these metal parts, due to the gas containers knocking against the closure rod, up to non-functionability of the closing device. According to the invention, such wear is ruled out by a rigid design of the closure rod (5) and of the holding elements (1, 1') made of plastic material. The closing device is composed of a closure rod (5) which is preferably T-shaped in cross-section and two holding elements (1, 1') which are fitted over it in mirror image and are placed with a U-shaped hooked part 2 against a longitudinal bar (6) of the skeleton box (8) in each case. The closing device (1, 5, 1') which holds itself together is operated by displacing it along the longitudinal bars (6), devices serving for bounding (7) the displacement path towards the bottom and for retention (9) in the uppermost position. The skeleton box (8) is preferably likewise made of plastic in a rigid design. <IMAGE>
