Abstract: In an expanded electrical discharge heater (1) a moveable discharge source is provided with a drive linkage comprising two separately but simultaneously operable linkages, each of which may be a crank (4) motivated arm (5), each linkage being capable of applying a reciprocating movement to the discharge source at an angle to that applied by the other linkage. By control of the frequency ratio and phase shift between the reciprocating movements complex path patterns of the discharge source may be achieved thereby enabling wear to be more evenly distributed about the discharge source and the heater interior. A high proportion of the cross-section of the heating chamber (14) may be traversed (15) giving the possibility of an increase in the effective capacity of the heating chamber and of a lengthened residence time in the heating chamber.

Abstract: A shock absorber comprises a piston (100) reciprocably disposed in a cylinder (32), which piston (100) is sized small enough to permit the shock absorber being successfully compacted. The piston defines therein a vortex chamber (128) with a maximum radius. The vortex chamber (128) communicates with a fluid chamber (48, 50) defined in the shock absorber via vortex passages (106,114,120) formed in the piston (100). The vortex passages. extend in a ceiling (112) or a bottom of the piston and tangentially open at the upper and lower plane periphery of the vortex chamber (128). By providing the vortex passages in the above-mentioned manner, the radius of the vortex chamber (128) can be maximized in relation to the radius of the piston (100). This helps to reduce the size of the piston (100) and, in turn, to compact the shock absorber.

Abstract: This relates to a method and apparatus for welding thin walled sheet steel tubular members of the type primarily intended for use as container bodies. The sheet steel may be provided with a suitable coating, such as tin plating, and is preferably heated by induction heating. The heated edge portions of a rounded tubular member are initially pressed together to effect bonding or welding, after which they are engaged by forge rolls to reduce the thickness of the resultant seam. The pressing together of the edge portions to initiate bonding is preferably effected between two coated surfaces, such as ceramic, with the pressure being applied by one of the members in the form of a spring loaded pin. When the eiectri- cal energy is induced into the edge portions, there is provided ° a secondary coil having a bore therethrough through which the rounded tubular member passes with the coil serving to size and guide the tubular member. The coil has associated therewith a core structure for effecting the concentration of the electrical current in the overlapped edge portions.

Abstract: A floating wedge is described for facilitating the mounting of an indexable insert in a pocket of an indexable cutting tool. The floating wedge includes a main body member having opposed leading and trailing surfaces and a swivel plate member having opposed leading and trailing surfaces. The leading surface of the main body member and the trailing surface of the swivel plate member are disposed in abutting relationship and are provided with complementary configurations, thereby enabling the relative slidable movement between the members such that orientation of the leading surface of the swivel plate member relative to the trailing surface of the main body member may be adjusted. The adjustability between the members enables full and equal contact pressure to be established between the floating wedge, the indexable insert and the walls of the insert pocket, thereby eliminating localized stresses and preventing insert failure. In a preferred embodiment of the subject invention, the trailing surface of the main body member and the associated wall of the pocket of the cutting tool are provided with complementary configurations. The latter arrangement allows for the relative movement between the leading surface of the swivel plate member and the walls of the insert pocket, thereby increasing the range of the floating wedge.

Abstract: This invention provides oxygen permeable, inherently wettable optical devices useful as corneal, scleral or intraocular lenses. The lenses are composed of a cured polysiloxane resin having a water-in-air contact angle no greater than 80°. The polysiloxane resin is prepared from an acrylate-functional polysiloxane composition containing at least 30 mole percent of H 2 C=CRCOOR'SiO 1.5  units and any remaining siloxane units present in the composition are R"SiO 1.5  R" 2 SiO and/or R" 3 SiO O . 5  where each R is -H or -Ch 3 , each R' is a divalent alkylene radical of 1 to 4 carbon atoms and each R" is an alkyl or haloalkyl radical of from 1 to 3 carbon atoms, a phenyl radical or hydrogen. The inherent wettability results from the level of the specific type of acrylate-functional siloxane units present. In an alternative embodiment, the physical properties of the device are improved by the inclusion of up to 30 weight percent of compatible aliphatically unsaturated organic compound such as methyl methacrylate.
