Abstract: SNOW REMOVAL APPARATUS          Abstract of the Disclosure The invention is concerned with a snow removal apparatus adapted to be mounted on a vehicle, for removing snow from a light fixture protruding from the ground.  The apparatus of the invention comprises means for providing a flowing stream of air and nozzle means connected to the air stream providing means for directing the air stream at the ground, the air stream providing means and nozzle means being adapted to pro-duce a directed stream of air having a flow velocity of at least about 180 m.p.h.  The nozzle means is adapted to be operatively positioned adjacent the ground at an angle to deflect the directed air stream on the ground at a predetermined distance from the light fixture so as to cause the deflected air stream to impinge on the light fixture at a reduced velocity sufficient to remove snow therefrom without damaging same, and to spread over a surrounding area with suffi-cient pressure to clear the area of snow.

Abstract: FACE GUARD MOUNT FOR HELMETS          Abstract Shock absorbing mounts (22) for the face guard (21) of a helmet  (20) having a substantially rigid shell and being connected to the shell allow substantial movements of the face guard relative to the helmet shell in response to forceful blows on the face guard (21). The mount protects the head of the wearer of the helmet from severe shocks and also prevents severe deformation of the helmet shell likely to crack it.  The mount (22)  can be installed at all points of attachment of the face guard  (21) to the helmet (20) to provide a resilient anchorage for the face guard without loss of security.

Abstract: ABSTRACT            Mineral Insulated Electric Cables and Like Elements.       In a mineral insulated electric cable the powdered insulating material is impregnated with a quantity of a hydrophobic material, for example a silicone, which has been introduced into the powder in liquid form. The added hydrophobic material serves as a barrier against the ingress of moisture, and liquid dimethylpolysiloxane has been found particularly effective, the presence of even a small quantity of this preventing any significant degree of moisture penetration into the cable.

Abstract: Abstract of the Disclosure Hydraulic Hose Assembly and Method High-pressure hydraulic hoses are employed in hydrostatic drive systems to interconnect the transmission and motors thereof.  It is imperative that fluid leakage be held to A minimum, or preferably eliminated, particularly where a vehicle employing the drive system is operated in a high-temperature environment, such as a foundry.  The hose assembly of this invention provides a high degree of system reliability, relative to hydraulic leaks, and shields a high-pressure hose thereof against damage and heat conduction to hydraulic fluid therein.  The hose assembly comprises a flexible high-pressure hose, an impervious flexible jacket surrounding the hose in out-of-contact relationship therewith to define a fluid chamber therebetween, and a mounting assembly for mounting the hose and the jacket on a support member to maintain them in out-of-contact relationship relative to each other.  The mounting assembly includes a first mount for securing the hose on the support member under a predetermined first sealing pressure, and a second mount for securing the jacket about the hose and on the support member under a predetermined second sealing pressure that is less than the first sealing pressure.          Method steps are taught for assembling the hose assembly in this manner.

Abstract: ABSTRACT OF THE DISCLOSURE The invention contemplates improved extraocular-lens  structures for contact with the cornea of a human eye, to be worn in place of spectacles.  The construction features a lens element of requisite prescription power but of diameter which substantially equals or only slightly exceeds the fully dilated pupil side of the wearer, and fenostrated haptic structure peripherally engaged to the lens.  The haptic structure extends radially outwardly and is so thin and axially compliant as to be self-conforming to the curvature of the cornea and to effectively adhere thereto, thus stabilizing the lens for retention of its position on the optical axis of the eye.  The haptic structure is formed by two sheets of transparent material laminated to opposite sides of the lens and to each other.  The effective surface of the haptic area is reduced by photographically delineated milling to fenestrate the haptic structure radially outwards of the lens.
