Abstract: A headlamp holder device for use with a user's helmet having an outer generally convex shape including a base member having an upper surface and a lower surface having a generally concave curvature so as to conform to at least a portion of the convex outer surface of the user's helmet; an upper member having a pair of opposing support members extending outwardly and upwardly in a lateral direction to the base member providing a support for mounting a conventional underwater self-powered flashlight thereon. The upper member includes a strap for releasably attaching the flashlight on the upper member. The upper member is pivotally attached to the base member so that the light beam of the flashlight is selectively adjustable in a forward vertical arc direction by the user. The headlamp holder device also includes fasteners for releasably attaching the base member to the user's helmet. In a preferred embodiment the headlamp holder device is formed of a lightweight rigid plastic material.

Abstract: A snap-in type fastener for securing an object to an apertured support includes a shank member having predetermined diameter and length. A locking member integral with one end of the shank member is provided to extend through the support aperture to facilitate engaging of the apertured support by the shank whereby the locking member resists withdrawal of the fastener from the apertured support. A head member is disposed at the other end of the shank member and includes a resilient member which provides for axial deflection of the shank for a selected distance in the direction of the apertured support to facilitate engaging of apertured supports of different thicknesses. The resilient member may form all or a portion of the head member depending upon the method of securing or may be associated with the head member.

Abstract: A portable breathing device is disclosed comprising an upper conduit section having an opening in one end to communicate with at least the user's oral passages and a breathing aperture in the other end and a lower flexible and inflatable respiratory gas container section for receiving and containing ambient respiratory gases. The respiratory gas container section has an upper opening communicating with the breathing aperture of the upper section and a lower opening relatively larger than the upper opening for communicating with ambient respiratory gases to thereby permit the user to entrap a volume of ambient respiratory gases within the respiratory gas container section. A seal device is provided for releasably sealing the lower opening of the respiratory gas container section to ensure containment of the entrapped volume of ambient respiratory gases. In the preferred embodiment the upper conduit section is provided with a facial mask adapted to enclose the oral and nasal passages of the user.

Abstract: A interim holder of open framework construction for computer diskettes comprising a base portion including a rear member, a pair of forwardly extending side members, and end members which preferably extend downwardly from the respective forwardly extending side members to provide an inclination of the plane of the base member from the rear member to the forward end members. An upper rack portion is attached to the base portion and includes a pair of rearward elements which extend upwardly from the respective base side members with angular members having portions extending laterally, forwardly and inwardly from the respective rearward elements and forming an overall generally rectangular configuration in the horizontal plane, the angular members providing respectively rearward, lateral and forward support to diskettes in the holder.

Abstract: An apparatus for removing contaminants generated in a volume of air contained within a work structure includes a housing, an inlet aperture disposed in the housing for receiving the contaminated air generated in the structure, an outlet aperture for passing of filtered air disposed in another portion of the housing removed from the inlet aperture and a plurality of removable interchangeable filter units disposed in the housing in spaced relationship between the inlet and outlet apertures thereby forming a plurality of chambers each defined by adjacent filter units and the housing. A detector device is engaged with at least the first chamber adjacent the inlet aperture for detecting the level of concentration of contaminants in the air passing through the chamber.

Abstract: A portable/disposable decontamination enclosure unit comprising a frame system which includes first and second rectangular end members and at least two pairs of opposing vertical frame members having opposing ends attached to the first and second rectangular end members, the frame system being adapted to be manually extended from a retracted closed position to an extended open position in which position the frame system forms a generally oblong configuration. The extended frame system is enclosed by a length of lay-flat material substantially impermeable to particulate material forming a bag enclosure member, the bag member being flexible and collapsible and closed at one end to form the bottom of the bag, the other end having a rim edge defining an upper opening to receive the frame system, the bag member being sufficiently long to enclose the frame system when extended.

Abstract: The present invention pertains to a structure resistant to the transmission of forces of impact which is useful in the fabrication of articles subjected to impact forces by the user of the articles. The structure includes a double plush-like open mesh structure having first and second layers of interlaced stretch-resistant flexible strand material positioned adjacent each other, and defining an intermediate space therebetween. A plurality of elongated partitions are disposed between the first and second layers and divide the intermediate space into a plurality of elongated generally parallel channels. The partitions each comprise a plurality of pile stretch-resistant strand material connecting with the first and second layers in a plane generally perpendicular to the first and second layers.

Abstract: A device for stripping and receiving cladding material from an elongated body includes a flexible bag means having an upper portion adapted to surround a first section of an elongated body and a lower portion extending below the first section of the elongated body for receiving and retaining cladding material removed therefrom and first and second laterally extendable sleeve members which are attached to opposing sides of the upper portion of the bag means and adapted to surround adjacent sections of the first section of the elongated body. The bag means and sleeve members define a sealed enclosure about the elongated body sections. Each sleeve member has an expandable length greater than adjacent sections of the elongated body which they surround whereby the extendable sleeve members permit the bag means to be moved into positions below each of the adjacent sections of the elongated body surrounded by each sleeve member to receive and retain cladding material stripped therefrom.

Abstract: A bow facing rowing system comprising the combination of an oar reversing device and a bracket device for supporting the oar reversing device. The oar reversing device includes a housing having opposing ends which terminate in a pair of upper and lower flanges defining fixed spaces therebetween. A train of gears is disposed essentially within the housing with one end gear of the train of gears forming a first terminal gear having an integral extension passing through the adjacent fixed space and terminating in an oar member and the opposite end gear of the train of gears forming a second terminal gear having an integral extension passing through the adjacent fixed space and terminating in a handle member. The gears intermesh in the same plane to thereby transmit motion in reverse from the handle member to the oar member.
