Abstract:
Hot-rolled high-strength steel elongated structural members and method of making same are disclosed by hot-rolling high-strength steel having a specific chemical composition to provide structural units. The units are then welded together to provide structural members of desired geometrical configuration including a thin web with opposed thicker flanges extending therefrom to increase the load bearing capacity of the members.
Abstract:
An optical bilge pump apparatus has two optical fibers with gaps cut therein and associated light transmitters-receivers. The apparatus is responsive to high and low liquid levels in the pump such that the pump is turned on when both gaps in the optical fibers are submersed in liquid, and the pump is turned off when both gaps in the optical fibers are not submersed in liquid.
Abstract:
A cage with bearing balls' confined therein is interposed between a plate and a planar platform, to accommodate rotation of the plate, and an electrically-powered device, such as a searchlight, can be fastened to the plate for rotation therewith. A disk, with a plurality of radially-extending fingers, is secured to the platform and is in biasingly restraint of the plate to (a) inhibit an unwarrantedly free rotation of the plate, i.e, to impose a controlled drag on the plate rotation, and (b) to enable the inverted operation of the overall combination.
Abstract:
Clutch apparatus with a rotary inner member having a plurality of equally spaced indents. An outer member has a plurality of equally spaced flexible beam members on its inner peripheral surface, each of said members being adapted to engage one of said plurality of indents. When either the inner or outer member is subject to an overload condition, said beam members flex radially outward and slip from one indent to another.

Abstract:
A portable golfing aid conditions the golfer to swing on a constant arc by limiting and restraining the pivot foot from lifting or pivoting. Base members which are spaced a shoe width apart are removably secured with respect to the ground or mounted on a pad or mat. Slotted portions of the base members receive a removable adjustable strap which connects the base members and bridges the front instep portion of the golfer's shoe and may be angled snugly across the instep. The golfing aid may be equipped with foldable ground engaging legs and when folded collapses to fit in a pocket in a golf bag. A less portable mat-mounted device is provided with pivoting adjustability for an angulated foot position.
Abstract:
Apparatus is described for a searchlight in which a lamp is mounted in a housing for both vertical and horizontal movement. Vertical drive means which is mounted in the housing includes a gear having a tooth portion and a ramp portion to permit up and down movement of said lamp. The housing has an integrally formed ring gear with a tooth portion less than 360 degrees and a ramp portion. A horizontal drive means engages the ring gear and drives the lamp in a horizontal plane less than 360 degrees.
Abstract:
Clutch apparatus having a rotary inner member with axially extending flexible members that engage complimentary cavities in an outer rotary member. When a predetermined value of torque is exceeded, the flexible members slip in the cavities of the outer member.
