Abstract: An intraocular lens, in the form of a disk, intended to replace the crystalline lens of a patient's eye, in particular after cataract extraction, comprises on its distal side, an aspherical sector extending approximately from the midline of the disk over one quarter of the surface thereof. The rest of the distal side is spherical. The radius of curvature of the aspherial sector varies monotonously between the value of the radius of the spherical sectors and a lower value. Such a configuration allows light rays impinging on the intraocular lens to be refracted at different angles and provides both near and distant vision. The discontinuity at transition between the aspherical sector and the spherical sector is blocked out by dark or etched plastic to eliminate glare. The proximal side can either be a convex surface, a concave surface or a plane.
Abstract: A paint brush receptacle engageable with the peripheral edge of an open paint can comprising a bottom wall, front, back, and a pair of side walls upstanding from said bottom wall and terminating at an open end for receiving paint brushes therein; the bottom wall having an extension projecting exteriorly outwardly therefrom; a leg depending from said extension and spaced from said back wall for insertion into said paint can and releasably engageable with said peripheral edge of said open paint can; a scraper extending outwardly from said extension for scraping paint off said paint brush into said open paint can.
Abstract: An aerobic exercise platform comprises a rigid base having a smooth and slick surface for practicing sliding exercises. Elastic or rigid holding elements are securable to a series of anchoring points located about the periphery of the base. An alternate embodiment of the invention combines a sliding exerciser with a stepping exercise stool. The stool is constituted by the two symmetrical halves of an enclosure housing a web wound around a drum. When the two halves of the enclosure are spread apart the web is deployed. The slick upper side of the web acts as a sliding surface.
Abstract: A safety anchor for the attachment of safety lines or supporting lines for suspended equipment, comprising a base plate adapted to be secured to a structure; a fastening wall projecting upwardly from said base plate, with a primary aperture fastening location adapted to receive a first line, and secondary aperture fastening location adapted to receive a second line.
Abstract: Imitation bricks made of molded plastic are linked by hinged connectors to form edging strips for flower beds, lawns or garden paths. Compressible rectangular washers between the bricks simulate mortar joints. Anchoring prongs with barbed tips are used to implant the blocks into the soil.
Abstract: A tool for temporarily laying a protective length of masking tape over the edge of a carpet along the base of a wall about to be painted, has a flared tape-laying roller that inserts a lateral portion of the masking tape between the edge of the carpet and the base of the wall down to the floor.
Abstract: Proximity switches and circumferentially movable stator windings allow a motor-generator to simultaneously sense and switch from a synchronous motor position to a synchronous generator position. This mechanism replaces the conventional separate sensing and switching of motor-generator functions. Automatic rotational repositioning of the stator maintains constant voltage and prevents the generation of transient voltages or harmonics. The stator flux leads the rotor magnetic flux slightly in an import power or motor position, creating a torque on the rotor and a counter torque on the stator reacted by the fixed casing of the apparatus. As the stator field weakens due to a failure of the normal power supply, the counter torque also weakens and the stator windings is biased to begin to turn with the rotor until the rotor and stator fields are in step, i.e., when virtually no current is generated or consumed or until a full export power or generator position is reached.
Abstract: A non-reusable hypodermic syringe is provided which comprises an elongated cylinder open at one end and substantially closed at the opposite other end. A hollow member is formed on the other end, which hollow end defines an internal duct communicating with the interior of the cylinder. The hollow member is configured and dimensioned to have a hypodermic needle affixed to it. The syringe plunger is comprised of a substantially rigid shaft and a resilient piston releasably attached to a first end of the shaft member. The piston fits into the interior of the cylinder in longitudinally sliding, frictional sealing engagement therewith. An engagement member is positioned on the piston member, and a retention member is positioned on the interior wall of the cylinder adjacent to, but spaced from the other end of the cylinder.
Abstract: An apparatus for composing individualized sales presentations created by various data sources from customer profiles managed by organizational hierarchy matrixes directed by multiple operating programs. The apparatus provides the means for synergistically creating and displaying customized presentations in a convenient manner for both the client and salesperson to achieve a more accurate, efficient and comprehensive marketing presentation. Organizational hierarchies of data sources are arranged so that an infinite number of sales presentation configurations can be created. Multiple microprograms automatically compose the sales presentations initiated by determinants received from client profiles stored on optical memory or smart cards, sales agent assessment of client profiles or centralized sales systems responsive to client profiles.
Abstract: Poly(alkylene ether) amines having the formula: ##STR1## wherein A is an amine moiety having at least one basic nitrogen atom; R.sub.1 is a hydrocarbyl group having a sufficient number of carbon atoms to render the poly(vinyl ether) amine soluble in hydrocarbons boiling in the gasoline or diesel fuel range; R.sub.2 is an alkylene group having 2 to about 8 carbon atoms; R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7 and R.sub.8 are each independently hydrogen or a lower alkyl group having 1 to about 4 carbon atoms; R.sub.9 is an alkyl group having 1 to about 10 carbon atoms; m is 0 or 1; n is an integer from 5 to 99; and W is a hydroxy(oxypropylene) group having the formula: ##STR2## or mixtures thereof. The poly(vinyl ether) amines of formula I are useful as fuel additives for the prevention and control of engine deposits.
Abstract: An apparatus for collecting insects or small objects combines a vacuum cleaner and a disposable trap made of paper and mounted in the intake orifice of the vacuum cleaner hose. a frusto-conical funnel is wedged into the mouth of the trap to secure it and to prevent its collapsing under suction of the vacuum. The trap has a flap to confine the collected items for disposal or preservation.

Abstract: A buried contact is formed in a substrate implantation of phosphorous or arsenic through a window cut into the insulating silicon oxide layer and a superimposed thin silicon layer. The photoresist used to etch the window is cut back a limited amount prior to implantation. The peripheral margin of the buried contact implanted through the exposed part of the thin layer of silicon lowers the threshold voltage of any parasitic MOS device which may be created between the buried contact and the remote N+source or drain structure.
Abstract: A circuit for automatically addressing and activating redundant circuits on an integrated circuit chip during testing, thereby improving efficient use of the space available for fuses and fuse pads. The circuit uses an integral number of fuses, whose blown and unblown combination represents 2**n possible states. Each state represents the address of a particular circuit or set of circuits gone bad on the chip which needs to be replaced. By employing an incrementor, the logical address representing the circuit or set of circuits physically adjacent to the bad circuit is also replaced. More sophisticated incrementors may be used to address more than one adjacent circuit or sets of circuits having a non-incremental address.
