Abstract: A fluorescent illuminating apparatus includes a translucent housing with a chamber within which a fluorescent medium is supported and electrical connections configured to provide an electrical potential across the chamber. An inductive-resistive structure is fixed sufficiently proximate to the housing to induce fluorescence in the fluorescent medium when an electric current is passed through the inductive-resistive structure while an electric potential is applied across the electrical connections of the housing. Preferred inductive structures for use with the present invention include elongate tape structures having a substrate with a conductive-resistive coating. A method of inducing fluorescence comprises passing a current through an inductive structure which is adjacent a fluorescing medium in an amount sufficient to induce fluorescent in the fluorescing medium in the presence of an electrical potential imposed on the fluorescing medium.

Abstract: The temperature adjustable coating and medium and method for providing an electrically-resistant temperature-adjustable article and structure. The coating provides a continuous electrically-conductive electrically-resistive path for the application of electrical current to the coating. The electrically-resistant temperature-adjustable article consists of a surface on which a high-temperature conductive-resistive coating is bound. The surface temperature of the article along the path is thereby adjustable between ambient and 2000.degree. F. in response to electric current applied to it without oxidization destroying the electrical conductivity of the medium in temperatures above 600.degree. F. The medium possesses the high-temperature conductive-resistive quality of the coating while maintaining a clay consistency capable of being formed into various shapes without a substrate.

Abstract: A fluorescent illuminating apparatus includes a translucent housing with a chamber within which a fluorescent medium is supported. The fluorescent medium and housing may be part of an ordinary fluorescent lightbulb. The housing has electrical connections configured to provide an electrical potential across the chamber. An inductive structure is fixed sufficiently proximate to the housing to induce fluorescence in the fluorescent medium when an electric current is passed through the inductive structure while an electric potential is applied across the electrical connections of the housing. It is believed that the inductive structure induces fluorescence by means of an electromagnetic field interaction with either the fluorescent medium, or the ultraviolet-emitting gaseous material, such as mercury, typically contained in a fluorescent lightbulb, or both.

A process of making the article is also disclosed.

Abstract: An electrical resistance heating element includes a pair of spaced apart electrical conductors, and a strip of resistive material disposed between the conductors and extending along their lengths. A strip of heat-sensitive, electrically conductive material is also disposed between the conductors and also extends along their lengths. The strips of resistive material and heat-sensitive, electrically conductive material together provide an electrical path between the conductors widthwise along their lengths. The heat-sensitive strip interrupts an electrical path between the conductors and widthwise through the resistive material strip only over portions of the resistive material strip which attain a predetermined temperature.

Abstract: Method and apparatus for enabling a person to relax and enjoy the outdoors on a hot humid day, without being continuously exposed to water which is uncomfortable for many people. A thin flexible cooling mat is positioned upon a lounge chair or is placed flat on the ground or worn in the manner of a vest. Ordinary tap water circulates through the mat, and since the water is supplied from a conventional in ground supply main having a substantially lower temperature than the air, the person's body, in direct contact with the mat, will be kept cool. The cooling water may irrigate the backyard at the same time. Since an entire family can relax while being cooled in their back yard, air conditioners will be turned off to save money, conserve electrical power, and thus reduce atmospheric pollution.

Abstract: Very simple, inexpensive keyless window sash combination code lock has a pivotable cover plate for preventing an intruder from unscrewing the conventional screws for mounting the lock to the sashes. Three combination code dials are slip coupled to associated rotatable pins which pass through the cover plate and an apertured anchor plate. The pins have lugs positioned under the anchor plate to prevent the lock from being opened. When the lugs are positioned within the anchor plate upon installation, the user rotates the dials to create his own custom combination code. The cover plate is then lowered, the dials are rotated and the lock is locked. The code dials are press fitted about the cylindrical locking pins to save manufacturing costs, and the manual sensing of the correct positioning of the code dials by an intruder, to open the lock, is prevented by providing radial dummy recesses in the lower surface of the anchor plate about each locking pin.

Abstract: Ordinary inexpensive magnetic recording tape is used to create a novel resistance element which may be made pressure sensitive to perform a number of tasks involving robot finger control intrusion alarm systems, and portable weighing scales. A pressure insensitive resistance element is also used as an efficient, inexpensive heating tape element, or to make precision resistors having little bulk, and resistive networks which may be customized by a user.

Abstract: A number of bearers concurrently use card-keys, having a common access code, and a unique lockout code to open a single lock. If a particular bearer is to be selectively locked out, the lockout code sensing device in the lock is changed to lockout the particular bearer but not all other bearers concurrently using their card keys to open the same lock.

Abstract: A first set of pivoted latching fingers having hook ends facing in a first direction are provided, together with a second set of pivoted latching fingers interlaced with the first set in accordance with a particular combination which unlocks the device. The fingers of the second set of latching fingers have hook ends facing in a direction opposite to the direction of orientation of the hook ends of the first set and actuation of only the proper combination of fingers causes the hooks of all fingers to be displaced away from a pair of facing lock anchor members to unlock the lock. All of the fingers are pivoted so that slight amounts of magnetically permeable material in the card key are sufficient to move the hooks of the pivoted latching fingers bearing permanent magnets, through a substantial distance, to enable the use of a thin, flexible card key for positive lock actuation.

Apparatus is provided for pivoting the support with the cushion attached thereto as the wheel chair is folded.

Abstract: A punch press comprising multi-station, progressive die tooling, for providing metal covers with easy-open closures, is fitted with a work transfer mechanism facilitating successive positioning of the covers, the tooling employing features thereof to precisely locate and align the covers in the respective stations. More especially, in addition to cover operating dies and work supporting members facilitating lateral accommodation and positioning of the covers to avoid unwanted deforming stress therein, correct vertical alignment of the tooling at successive stages to produce the closures is economically assured.

Abstract: Certain articles, including easy-open sheet metal can tops or covers, include closures which are, at least in part, defined by indentation and/or fracture through the metal. This invention provides a high speed mechanism for coating particular portions of the articles, for instance for sealing only the fractured locality of each successive cover, a shallow printing on applicator being in timed communication with a source of hot pressure fluid such as a hot melt or lacquer. A hold down or backing member precisely cooperates with the applicator in relative reciprocable, high speed to insure that sealant fluid is applied to the predefined locality of the article, and resilience in the article and/or sealing means such as O-rings of the applicator is, in effect, relied upon to provide dwell during the moment of coating thus providing rapid, economical production.
