A lawn mower is described having a high collection efficiency. This is accomplished by constructing a housing having a toroidally-shaped skirt defining the interior space in which the blade rotates in a horizontal plane. The interior space has a generally circular cross-section, the radius of which gradually increases toward a region of maximum radius between upper and lower portions of the housin...

A laser coagulation system projects a slit image beam into an eyeball to determine a treatment point and selectively delivers argon and krypton laser beams thereto during an opthalmological operation. Observation equipment receives the slit image beam and laser beams reflected from the treatment point to observe the treatment point. A pair of discs are coaxially rotatably mounted around a shaft pa...

In association with a vehicle designed to carry a heavy load module, an improved means for accurately guiding the module onto the vehicle bed surface as the module is being lowered into position. The improved guide comprises a plural number of specially formed nuts carried on the studs that are used to fasten the module to the bed surface. Each specially formed nut has a conical external surface t...

A process for producing a composite by embedding a porous body at least partly composed of a substance which reacts with silicon in a powder mixture composed of silicon and hexagonal boron nitride powder, heating the resulting structure to a temperature at which the silicon is fluid and infiltrating the fluid silicon into the porous body.

A copper electrode is firmly bonded to a sintered aluminum nitride body by applying a copper film on a sintered aluminum nitride body by electroless or electrolytic plating, evaporation or sputtering, and heat treating the copper film on the body at a temperature of 900 DEG to 1083 DEG C. in a weakly oxidizing atmosphere.

A composite comprised of a continuous matrix phase having a ceramic filler phase distributed therein is produced by shaping a mixture of ceramic filler and a solid constituent of the matrix into a compact and infiltrating the compact with a molten constituent of the matrix which combines with the solid constituent by dissolution and/or diffusion to produce the matrix in situ.

Bridged dense star polymers having terminal group densities greater than conventional extended star polymers exhibit greater and more uniform reactivity than their corresponding conventional star polymers. For example, a third generation, hydroxy-terminated polyether dense star polymer can be prepared from pentaerythrityltetrabromide and 4-hydroxymethyl-2,6,7-trioxabicyclo[2.2.2]-octane which has ...

A device for processing optical data comprising: an optical waveguide formed on a substrate, a light source for the laser beam to be admitted into the waveguide, lens means provided on the waveguide for causing the beam propagating through the waveguide to emerge obliquely upward and focusing the emergent beam two-dimensionally, means for receiving the beam reflected obliquely from above, a base p...

An improved ride-on rotary lawnmower comprises a cutter device having one or more blades rotating about an axis substantially perpendicular to the ground and contained in a downwardly open casing provided with a rear duct for the discharge of cut grass. The casing of the cutter device of the lawnmower is mounted between front wheels and rear wheels. The bottom of the rear duct of the cutter casing...

A transport refrigeration system suitable for narrow post highway trailers in which the refrigeration system intrudes into the trailer cargo space only to the extent necessary to direct trailer air into an evaporator. The evaporator is completely serviceable external to the trailer, with its inlet surface being substantially co-planar with the inside surface of the front wall of the trailer. An ai...

A pair of projecting brackets positioned toward the front from the steps of the tractor extend laterally outward from front portions of the pair of mount members and are provided with a pair of opposite mount portions for a front loader and with a pair of opposite f...

A polyolefin blend comprising, in physical admixture, a major portion of particles of a first polyethylene and a minor portion of particles of a composition of a second polyethylene, is disclosed. The first polyethylene is selected from the group consisting of homopolymers of ethylene and copolymers of ethylene and at least one C4-C10 higher alpha-olefin, and the second polyethylene is a copolymer...

The field rate of a video input signal is doubled by storing each field in a memory and recovering each stored fields twice so as to repeat each field and thus reduce flicker. To ensure that even fields overlay even fields, odd fields overlay odd fields and that all pairs of even and odd fields are interlaced, a timing unit provides a double field rate read control signal to the memory having a wa...
