  • Publication number: 20110192467
    Abstract: Abstract A flow means for cutting off/opening a flow of liquids or gases as well as for routing said flow, of the type that includes a body component that is manufacturable by injection molding and that is formed with a flow passage through it and has at least one sharp edge, circumferential along said flow passage. Wherein the flow means is characterized by that it includes in addition, a flow smoothening means formed as an insert that can be affixed to the flow means body component. The flow smoothening means is formed with a rounded surface that when affixing the flow smoothening means to the body component of the flow means, it integrates with the flow passage and converts the sharp edge into a rounded corner that contributes to smoothing said flow, reducing the tempest like effect of the flow and substantially preventing turbulence and generation of whirlpools.

  • Patent number: 4436181
    Abstract: An escape system (10) for lowering a user mounted thereon in a vertical direction (12) at a predetermined rate of descent responsive to a user applied force in predetermined areas on a seat member (22). The escape system (10) includes a mounting bar member (16) which extends in a longitudinal direction (18). The mounting bar member (16) is secured to a base surface (14) which may be a wall of an edifice, or some other vertically directed surface. A seat member (22) extends in the longitudinal direction (18) which provides containment or a seat for the user. A pair of first and second pulley members (32 and 34) are displaceably coupled to the seat member (22) through a rope element (36) passing between first and second pulley members (32 and 34) and cooperating with seat member (22).

  • Patent number: 4198090
    Abstract: An improved shovel (10) which includes the standard longitudinally extending handle member (12) having a scoop member (14) and a gripping member (16) rigidly secured on opposing longitudinally displaced end sections. The shovel (10) includes an adjustable lever mechanism (30) which is releasably secured and movably displaceable in a direction substantially normal to a longitudinal direction (20) in relation to handle member (12). Adjustable lever mechanism (30) is adapted to interface at a fulcrum point (38) with a base surface (18) to rotationally activate scoop member (14) when material is to be removed from base surface (18). An adjustable grip mechanism (50) is releasably secured and movably displaceable with respect to the handle member (12) and extends above the handle member (12) for providing a secondary gripping portion for a user.

  • Patent number: 4005945
    Abstract: A clamping and drill guide apparatus which is utilized by an operator to aid in manually drilling holes in work pieces which have an arcuate contour. The apparatus includes a first clamping member which has a multiplicity of openings axially passing through the first clamping member in a vertical direction. A second clamping member located in alignment with the first clamping member and below such includes a multiplicity of threaded through openings which axially pass in the vertical direction and are alignable with each of the through openings in the first clamping member. A pair of screw and nut members provide for clamping the first member to the second member when a work piece is inserted therebetween.
