An anchor in which an L-shaped shank has a single trapeziform fluke pivotally secured to the shorter leg of the L provides a larger surface area for the palm of the fluke. The fluke is configured such that a center of force is directed perpendicularly to the shorter leg of the L to minimize the tendency of the anchor to move sideways or crab.

A constant-on variable-stroke refrigeration thermostat is disclosed wherein the toggle spring-biased operating lever has a fixed-position stop when the contacts are open and a variable-position stop when the contacts are closed, and wherein an air gap is provided between the actuator prong of the operating lever and the moveable contact blade of the switch contacts to allow the operating lever to travel downwardly with increased momentum before the switch contacts are opened. The primary advanta...

A connector facilitates securing a boat canvas to a boat frame. One portion of a conventional snap is attached to a boat surface in a known manner. The complementary portion of the snap forms part of a two-sided connector, including a surrounding component with one half of a repositionable fastener facing away from the boat surface. In this manner, a boat canvas including the other half of the repositionable fastener can be readily secured to the boat. Preferably, a connecting force between the ...

There is disclosed thermoplastic polymeric compositions of polycarbonates, polyamides, polyacetals, and poly(2,6-dimethyl-1,4-phenylene oxides) and which contain in a minor amount sufficient to make the thermoplastic polymeric material easily releasable from a processing mold of fatty acid ester.

Method and apparatus for the anchoring of a floating object by an elongated shank having an attached fluke that extends along the vicinity of the shank, with an edge of the fluke extending to a tip from a constraint movably mounted on the shank, with the fluke apertured and proportioned to limit fouling by a rode attached to the shank and facilitate attachment for storage.

An anchor construction for fishing and pleasure craft, especially those with a power anchor line winch, which includes a center swivel plate in a plane transverse to an anchor blade. The centerplate has a V-slot in which slides a clevis attached to an anchor line to effect release of a snagged anchor without moving the boat over or past the anchor. A stop lobe on the anchor blade cooperates with the center plate to limit relative motion.

The invention has as its object a drag anchor which is simple to manufacture and provides an effective grip in the bottom material where the anchor is to be used, besides which the anchor can be executed with a very low weight. The invention, which relates most particularly to a drag anchor, the shank of which is pivotally attached to its part which forms the fluke, is characterized in that its part (2) which forms the fluke consists of a hollow body (2) open at its front and rear end in the dir...

A system for substantially eliminating nonlinear distortion, such as intermodulation products, introduced when a signal is processed by a nonlinear device. The system adds an out-of-band signal to an input signal to produce a combined signal having a power that substantially equals a nominal operating point power for a nonlinear device. Preferably, the instantaneous power of the out-of-band signal is adjusted by an automatic gain amplifier. The combined signal is input to the nonlinear device to...

Device and method for handling a material web, in which the material web is guided by at least one smooth support surface and is then guided together with a porous support belt to a deflection roll includes a suction box. The suction box has a wall opposite from the porous support belt, and creates a vacuum that draws the material web from the support surface to the porous support belt. The device also includes at least one sealing element positioned near a front end, in the web travel direction...

A non-fouling fluked anchor having a yoke-like shank in which the yoke arms are arcuate and pivotally attached to a pointed, center mounted fluke such that the arcuate arms of the shank provide for variable positioning of the fluke point to insure initial penetration of the fluke point in sea floor bottoms having different degrees of hardness. The fluke tip, the yoke frame, and the anchor line tether establish a three point contact with the sea bottom. The arcuate yoke shank arms allow a variabl...
