Abstract: A ski stiffness indicator comprising a type of a C clamp which receives a pair of skis placed bottom to bottom, and which can be used to force the middle portions of the skis together. The force required for urging the portions of the skis together is registered on a gage, and the flexing of the skis under a selected load indicates the stiffness of the skis, and thus indicates the relative flex to select skis for varying conditions. Also, the load required to make the skis touch along their length indicates the ski stiffness.

Abstract: A restraining belt includes an inboard lap belt piece connected to an outboard lap belt piece and a shoulder belt portion connected to the junction of the two lap belt pieces. One end of the inboard lap belt is received by a conventional inertia-lock belt retractor mounted rearward of a vehicle seat and inboard of it. An end of the outboard lap belt is received by a similar retractor mounted rearward of the seat and on the outboard side of it. An end of the shoulder belt is received by a third retractor mounted to a vehicle body rearward of the seat and adjacent to and above a frame for a vehicle door. There is a lower horizontal track adjacent the bottom edge of the door and door frame; and an upper track on the vehicle body along the uper edge of the door frame.

Abstract: A warning apparatus to indicate to a driver that the headlights of the vehicle have been left on after the ignition has been turned off includes a timer circuit which is operably connected to the ignition switch, the headlight switch, and the horn of the vehicle. The timer circuit energizes the horn for a predetermined period after the ignition switch is turned off while the headlight switch remains on.

Abstract: A strip cutting apparatus such as a photographic paper cutter senses position of the blade which cuts segments from the strip. The strip is driven in a reverse direction by a predetermined number of steps after the blade has cut the strip and before the blade is retracted. This back step motion or reverse motion eliminates the occurrence of interference between the forward edge of the strip and the blade as the blade is retracted. Damage to the forward edge of the strip caused by interference with the retracting blade is thereby avoided.

Abstract: A tractor having a hydraulically driven power takeoff shaft in which manipulation of a control handle in the forward direction causes the speed of the shaft to be varied in accordance with the position of the handle and also in accordance with engine speed. When, however, the control handle is moved to the extreme forward position, the power takeoff shaft is operated at either of two selected constant speeds regardless of engine speed as long as the engine speed is adequate to maintain such constant speed. When the control handle is moved in the opposite direction towards reverse position, the power takeoff shaft is driven at a variable speed, dependent on the position of the handle and on the engine speed. This speed is relatively low as compared with that of the forward speeds.The tractor is provided with a manually operated energy shutoff control adjacent the power takeoff shaft, in the form of a push button switch which can be actuated whenever a sudden termination of the shaft operation is desired.

Abstract: A paint roller for producing texture paint surfaces having a cylindrical core with a paint applying and texturing cover bonded to the outer surface of the cylindrical core. The paint applying and texturing cover is an open web of interengaged continuous crinkled coarse filaments of resilient material. The open loops of the open web carry the texture paint material, apply it to the surface being painted, and texture it in essentially a single motion. During application, the loop elements are actually immersed in the texture paint material and lift it into peaks, thereby producing deeper textures than has generally been possible in the past.

Abstract: A machine tool, such as a machine for reconditioning the valve guide bores of automobile cylinder heads, includes a support member for holding a work piece and a table for supporting the support member. A plurality of orifices are provided for supplying air to or removing air from between the support member and the table. An operator-controlled valve selectively connects either an air source to the orifices to provide an air cushion which permits positioning of the support member with respect to the table, or connects a vacuum source to the orifices which holds the support member in a fixed position with respect to the table.

Abstract: In a house structure in which insulating material is to be laid in between and over the attic floor joists, an insulation vent is provided in spaced relation to the roofing boards to allow for free flow of ventilating air between the soffit and the interior of the attic above the insulating material and along the roof boards. This insulation vent is sold flat. To be installed it is folded on pre-scored crease lines, first to form an elongated trough consisting of a rectangular roof clearing sheet and two upwardly extending roof contacting spacer flanges. A lower end portion of the roof clearing sheet is folded down to become a wall sheathing contact sheet, and the flanges which fold down with it are stapled to the roof rafters to hold the roof clearing sheet and sheathing contact sheet in place.

Abstract: A sheath arrangement for a male urinal device having a urinal sheath of flexible material, designed for application to a penis for covering a substantial portion thereof lengthwise of the same and having a lower portion for connection to a urine receptacle, and a liner pad of resilient, compressible, deformable, waterproof material in the form of a strip of such material having a width sufficiently narrow to allow the strip to be wound spirally to extend over a portion of the penis beneath the sheath much greater in length than the width of the strip. The material of the pad is sufficiently deformable to ensure liquid tight engagement of the overlapping portions of the pad with the penis. Preferably, both the inner surface and the outer surface of the pad are adhesive so that not only is the liner pad held in place on the penis but the sheath is also held against movement with respect to the liner pad. The sheath arrangement is formed by spirally winding the liner pad firmly around the penis.

Abstract: The present invention relates to a flow velocity measuring apparatus which provides a distinct, measurable pattern of vortices known as Karman Vortex Generation. The apparatus is arranged to include a plurality of vortex producing obstructions which co-operate to provide a high signal output. The flowmeter is designed to use a vibration sensor which is accessible from the exterior of the pipe carrying the fluid being measured.
