Abstract: Storage batteries and/or aggregates thereof are constructed to provide a high impact absorbency, so that their mass will serve a dual function: storing electricity and absorbing collision impacts.The collision protection for humans also involves two separate functions: impact absorption and gradual deceleration. The former is achieved by adding highly shock absorbent closed cell foamed metal plates to the battery aggregate, the second by spacing these in such a way that the impact absorption occurs gradually, so that the deceleration at no point exceeds that of 7 times gravity acceleration. To this end the battery aggregate is designed so that the shock energy absorption occurs in many centers or zones of the battery aggregate, thus providing a safe deceleration curve over a distance equal to the distance from leading side to trailing side of the battery aggregates as installed.

Abstract: Non-woven articles, including garments and porous sheet materials, are made from continuous filaments by ejecting continuous yarn or filaments into turbulent air and contacting them with binder in a high density fog while still suspended in air, so that the binder dries sufficiently to become non-migrating before the yarn is deposited on the screen or mold on which the fibers are brought into contact with each other and bonding takes place. This method is particularly suitable for making garments of elastomeric fibers, not easily handled in ordinary production machinery. Another generally applicable advantage is that the resultant products are exceptionally flexible and that the articles produced do not split into stratified binder-rich and-poor areas, but are uniformly bonded throughout.

Abstract: Fibers composed of mixtures of refractory metal oxides, other than silica, are treated by a process involving a drawing step to markedly increase the modulus of elasticity of the fibers. The compositions of the fibers to which the process is applied are typically mixtures of refractory vitreous metal oxides such as calcia, alumina, verylia and the like which are devoid or nearly devoid of silica or other network formers but may be a single such oxide mixed with no more than small or insignificant amounts of such other oxides.

Abstract: A combustion product detector contains a single ionization chamber having a radioactive source therein. It is provided with means to test the function of the device. The means includes an electrically non-conductive member which may be introduced in the ionization chamber to simulate (in effect) the presence of smoke in the chamber. Housing for the chamber is constructed and mounted to shield the components contained therein. An FET and resistors are closely coupled to a radioactive source holder and to a printed circuit board on which the housing is mounted. A metal coil spring electrically connects the non-conductive test member and the housing to discharge static. The test member may be removed readily to permit inspection and cleaning of the radioactive source surface.

Abstract: Grip member for elastic cord used for exercising contains two parallel cylindrical bores with slightly greater diameter than the cable, to slidingly receive the cable and prevent sliding of the cable through the grip member and permit adjusting of the active length of the cable used in any specific exercise. A tubular member receives one of the hand grip members in each end and may serve to simulate a bar used to lift weights, a golf club handle, a tennis racket handle, a baseball bat, a canoe paddle, a hockey stick, or the like. A device is provided to attach the cable at the juncture of a door and door frame.

Abstract: Device attachable to snowmobiles and other ice and snow vehicles which comprise an endless track or belt and a slide rail. The device engages ice, snow or water on the surface alongside the vehicle and throws or directs such aqueous material against the slide rail and portions of the belt adjacent the slide rail to lubricate the interface between the slide rail and belt.

Abstract: Closure for open top truck box body is a single rigid member which opens hingeably on a transverse axis near the upper front edge of the box body and has skirt portions which extend downwardly along sides of the box body in the closed position. Hydraulic cylinders open the closure and pressure of fluid supplied to the cylinders is limited to a pre-selected value so that the cylinders can only raise the closure itself and cannot raise it if it carries an additional load. Thus it cannot be operated to serve as a crane or hoist and cannot be raised if a person is standing on it.

Abstract: Hand operated device for transversely severing polymeric synthetic resinous tubular members comprises resilient plastic housing members which snap together and a finger operated sliding member which carries a portion of a razor blade mounted in a described manner.

Abstract: Means to remove snow loads from a roof includes a roof structure for a building and treating means within the building. The roof structure is characterized by flexibility and relatively high initial thermal insulation value and comprises a relatively non-yielding roof base, an elastically compressible insulating layer resting thereon, and a very light weight continuous top layer positioned outermost, so that the weight of this top layer will be considerably less than the expectable weight of a heavy snowfall. Snow on the roof compresses the insulation and reduces the thermal insulating value so snow on such roof will rapidly be melted by heat leakage through the roof, yet the previous high thermal insulation will be restored as soon as snow pressure ceases.

Abstract: Small articles such as springs are heat treated as they flow downward by gravity through a straight cylindrical tube. The tube need not be cylindrical or straight and means to assist gravity may be provided. The articles are heated by hot air or other gas introduced to said tube through apertures in its walls and which flows through portions of the tube at high velocity. Hot air thus introduced is withdrawn through other apertures in the walls of the tube in a manner to prevent heat loss by exhaust of the hot air at either end of the tube or by introduction into the tube of ambient cool air at either end of the tube.

Abstract: Steel wires are pulled through a reactor tube in which they continuously interact with a foaming metal mass. The steel wires are coated with a metal which forms a binary alloy with the matrix metal, thereby protecting the steel from being dissolved. The foaming matrix metal is usually an aluminum alloy but can be any light or low melting metal including zinc or lead. The steel wires protect the metal foam from cracking in the pultrusion process.

Abstract: The course to be followed by a motorist having a preselected destination is indicated by a plurality of markers set in the center of the path to be followed by the motorist, each set of markers having a different color to correspond to a different preselected destination.
