A swimming pool cover for preventing leaves and other debris from getting into the swimming pool, and which can be placed on the swimming pool and removed therefrom by one individual, includes a pliable mesh screen that covers the entire swimming pool, and the mesh screen includes a peripheral sleeve in which a flexible wiring is disposed for maintaining the disposition of the cover upon the pool. The swimming pool cover can be folded up and stored within a storage bag, and upon removal from the...

A lid support bracket assembly for supporting a pool cover box lid includes a wall mount and a bracket angularly adjustably coupled to the wall mount.

A swimming pool covering structure including a flexible covering section for extending across the top surface of water contained within the pool and a flexible anchoring section for extending peripherally and outwardly from the covering section. The covering and anchoring sections are separable from each other about a separation segment. The covering and anchoring sections are releasably attached together about the separation segment. The anchoring segment is anchored to an outer structural comp...

An insurance or warranty method protects financial interests of producers, such as farmers planting transgenic varieties of seed as a primary asset, who use proper refuges of similar but non-transgenic, secondary assets for maintaining a non-resistant pest population. Refuge acre methods, now sometimes called "refugia", as such are recently known in crop pest management, but producers have had no effective incentive and much risk in using them. That is, losses in the refuge from pests, as to cor...

A method and means for emulating realistic access requests used in static or dynamic performance testing of a disk-based storage subsystem. The method and means are based on the fact that a test driver can substitute for an actual application if an executing process generates a pattern of accesses to disk subsystem addresses as a prescribed random walk function among a cluster of contiguous tracks associated with the process. The access pattern will emulate both locality of referencing and the f...

Apparatus for covering a liquid basin, such as a swimming pool. The apparatus comprises a roller-blind type cover assembled from hollow slats arranged to be spread over the surface of the liquid. According to the invention the cover is constructed so as to be stackable accordion-wise by the side of a shaft or roller with which the cover is spread over the surface of the liquid or withdrawn from it, thereby to reduce weight on said shaft or roller compared with a prior construction in which the c...

The present invention is a method and system for providing a user with confirmation of the origin of a Web site and related information including the steps of registering a Web site with an assuring 3.sup.rd party, saving the registration on a registration server, entering in a database the Web site's Internet domain name and cross-referencing it to the registration data, retrieving the Web site's domain with an Internet browser, and either (1) using a client application tool to call for registr...

A retractable cover for protecting designated area and spaces. A stationary rigid portion receives telescopically extending portions movable over guiding assemblies to house vehicles and other objects and protect them. When the telescopic rigid portions are fully extended, they engage and interlock with seals resulting in a water tight structure. Also, the engagement is used to move and/or stop contiguous portions through the use of outwardly extending tabs at the rear and front ends of the tele...

An above-ground pool (1) having a protruding edge (3) and which can be covered with a cover (6): the folded cover, possibly enclosed in a bag (7) is anchored to a first location (P.sub.1); next, it is unfolded and drawn over the pool successively on either side thereof and it is successively anchored at two points (P.sub.2, P.sub.3) such that a line joining these two points is located at arm's length from a fourth point (P.sub.4) on the opposite side from the first point (P.sub.1); finally, it i...

Each of a plurality of changeover switches is provided at a corresponding one of a plurality of signalling stations and has a first contact terminal connected to the positive polarity terminal of a DC voltage source and a second contact terminal connected to the negative polarity terminal of the DC voltage source. Each of the plurality of transistor circuits is provided at a corresponding one of the signalling stations. Each transistor circuit comprises a PNP type transistor and an NPN type tran...
