Abstract: Abstract of the Disclosure A single sheet of standard grade plastic laminate material is bent at two locations to form it into a side wall and two end walls corresponding to the side wall and two end walls of a bathtub recess.  Following forming, one end wall portion of the wall covering is loosely folded over the opposite end wall portion.  Then, the partially folded wall covering is pushed endwise into a rectangular cardboard box having a normal thickness which is substantially smaller than the initial depth of the partially folded wall covering.  The box with the par-tially folded wall covering inside is moved through a rectangular opening provided in a rigid mandril, sized to be substantially equal to the normal outside dimension of the box. The mandril forces the outwardly bulging side walls of the box inwardly and reshaped both the side walls of the box and side and end walls of the partially tolded wall covering therein. In so doing, the end walls of the wall covering are slid in position an amount sufficient to cause the side and partially overlapped end walls of the wall covering to bow inwardly until the wall covering has assumed a new configuration which is substantially within the normal rectangular shape of the box. The frictional contact between the backing layer of the wall covering and inner surface portions of the box in contact there-with serve to hold the wall covering in such new configuration, so tha the box will retain a substantially rectangular shape.

Abstract: ABSTRACT OF THE DISCLOSURE An improvement in a process for the preparation of an ethylene homo-polymer or a copolymer of ethylene with an .alpha.-olefin containing 3 to 15 carbon atoms by contacting the monomer or mixture of monomers in solution, suspension or in gas phase at 20° to 250° at a pressure of 1 to 50 bar with a mixed catalyst comprising a chlorine containing titanium (III) compound and an organoaluminum compound in the presence of hydrogen, the improvement residing in employing as the organoaluminum compound a trialkylaluminum compound in an amount of 0.1 to 20 mol per mol titanium (III) compound and including in the polymerization mixture oxygen at a concentration of 0.001 to 0.1 volume percent based upon the amount of ethylene.  By carrying out the polymerization by including oxygen in the polymerization reaction mixture and employing tri-alkylaluminum compound as the organoaluminum compound the mean molecular weight of the polymer can be regulated while obtaining a desired molecular weight distribution.

Abstract: ABSTRACT    An improved waste material handling system including a plurality of waste food disposer units which are operable to disintegrate  waste food materials to form a slurry.  The system also includes a pulper unit which is operable to disintegrate solid waste materials, such as paper, cardboard boxes, plastic bags, etc., to form a slurry.  The waste material slurry is conducted from the waste food disposer units and pulper unit to a press which extracts water from the slurry.  To prevent the discharge of waste material slurry from an active one of the waste food disposer units to an inactive one of the waste food disposer units and/or the pulper unit, check valves are assoc-iated with each of the waste food disposer units and the pulper unit.  A pump is also associated with each of the waste food disposer units and the pulper unit to promote a flow of slurry from the units to the press.  Eductors having jet assist nozzles are advantageously utilized to direct a flow of fluid toward the inlet of the pumps associated with the waste food disposer units to promote a flow of slurry from an associated waste food disposer unit to the pump.  The amount of water required during operation of the system tends to be minimized by utilizing a pump to supply the eductors with water removed from the waste material slurry b  the press.  Since it is contemplated that the waste food disposer units may be activated at different times, control valves are provided to enable the water from the press to be directed to only an eductor which is associated with an active waste food disposer unit.

Abstract: ABSTRACT OF DISCLOSURE      A system for converting wave energy from the sea into electrical energy, comprises a floatable assembly which, in use, is moored at sea and which is capable of internal movement in response to the action of waves.  The assembly includes a hollow body mounted on a shaft and reciprocable angularly about the axis of the shaft in response to said internal movement.  The body and the shaft define respective parts of a pump which also comprises a pair of spaced, opposed annular cam tracks extending around the axis of the shaft and rigidly connected to one of the pump parts defined by the body and the shaft, and at least one piston and cylinder arrangement disposed between the cam tracks and rigidly secured to the other of the pump parts so as to extend substantially parallel with the shaft axis.  The cam tracks and the piston and cylinder arrangement thereby undergo relative angular movement about the shaft axis in response to wave-induced internal movement of the assembly, each of said cam tracks engaging an axially movable operating piston of said arrangement and being shaped so as to move the piston within the cylinder to displace fluid received in the cylinder in response to said relative angular movement.  The system further compreses an electricity generator which can be driven in response to displacement of the fluid in the cylinder.

Abstract: ABSTRACT OF THE DISCLOSURE           A truncated cone shaped pump support and fluid de-flector is provided with a plurality of intake apertures in the wall thereof and the pump is supported in the wall below the upper side of the sloping wall so that the intake is uppermost and situated above the intake apertures.  This main-tains the pump and motor submerged in solvent at all times for cooling purposes and also provides self-priming character-istics to the pump.  In conventional assemblies, if the pump is switched on for too long a period, most of the fluid will be pumped to the sink of the parts washing machine thus starv-ing the pump which, if fully exposed, can overheat and become damaged.  Furthermore, with conventional pumps, if starved of fluid, air locks often occur which prevents the pump from operating correctly once liquid or fluid is restored thereto.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention provides a system in which heat energy is stored chemically in and extracted from an energy accumulator containing a substance which contains less liquid in the charged, high-energy condition of the accumulator than it does in the discharged low-energy condition of the accum-ulator, which is associated with vapor condensing and generating means which is maintained at a low temperature as compared with the accumulator in which a liquid container is comprised.  Vapor is driven off from the accumulator substance and transferred to the vapor condensing and generating means when energy is stored in the accumulator, and is returned to the accumulator when heat energy is extracted therefrom.  The system comprising the accumulator and said vapor condensing and generating means is maintained substantially free from other gases than said vapor.

Abstract: ABSTRACT OF THE DISCLOSURE           An inert carrier process for drying radioactive waste material and for incorporating the dry material into a binder from which the dried material will not be leached is disclosed.          In this process, a hot inert liquid carrier is provided into which the solution to be dried is introduced under extremely turbulent conditions.  The solvent flashes off leaving the dried particles dispersed in the inert carrier which carries these particles to a mixing station where a binder for the particles is injected under turbulent conditions.  The binder preferentially wets the particles and the coated particles are carried to a sep-arator section where the binder coated particles coalesce and separate from the carrier as a second phase.  Thereafter a curing agent can be added to the binder.
