Abstract: A weatherproof telephone terminal apparatus includes a terminal assembly having a pair of terminal members included therein suitable for splicing insulated telephone wires of the same or different wire sizes in a single housing which is impervious to atmospheric conditions and may be used indoors and outdoors and may be installed in a clamshell-like housing, thereby eliminating the need for conventional splicing techniques.
Abstract: Process for manufacturing of structural aggregate pigment products with intrinsically built-in functional properties, from aqueous dispersions of particulate matter treated with in-situ formed complex functional microgels with rapid formation kinetics.
Abstract: A mathematical game apparatus includes a game board having a plurality of concentric circles providing paths or playing paths divided into a plurality of sections, each section being provided with indicia (numerals) therein for the purpose of having the players learn and/or improve their ability to count from 1 to 125 by multiple units in addition to increasing their acuity in utilizing prime numbers and factors; perfect squares and cubes; and exponential powers of 10.
Abstract: In production of a decorative board with overlaid wood pieces used for surface covering of various furniture, building materials and car interior decoration, wood pieces supplied from an overhead hopper by gravity are dispersed on a flat feeder by application of vibration and are transferred in a dispersed state onto base boards successively supplied by a transfer conveyor in a horizontal direction. Almost no need for manual operation raises production efficiency and dispersion by mechanical vibration assures high degree of uniformity of patterns on the products. Fully automatic processing enables reproduction of patterns with commerically acceptable fidelity.
Abstract: A back-up surge arrester is combined with a conventional gas filled surge arrester in axial alignment. The size of the air gap is held to a predetermined distance by aid of the mechanical configuration specified herein and further includes a heat sensitive material in a parallel breakdown path.
Abstract: A telephone line to utility meter interface for use in connecting a telephone line pair to a plurality of utility meters, includes a weather sealed and lockable housing with a telephone line cord plug and receptacle and a terminal block disposed therein. The incoming telephone line pair may be isolated from the utility meters for testing, via the insertion of a known operating telephone having a standard telephone plug into the receptacle within the housing which is integrally molded into the terminal block. The terminal block also includes integrally molded test cable retainer. The utility meters may individually be interrogated by the aid of electrical interrogation circuitry activated by a specific electrical signal appearing on the subscriber telephone line.
Abstract: A medical instrument for facilitating endotracheal intubation in a patient, the instrument including a handle and an elongated obturator element extending therefrom, the obturator element for releasably retaining thereon a selected endotracheal tube for positioning within the patient, a mechanism being provided for selectively retaining and ejecting the endotracheal tube from the obturator element, the obturator element accommodating therethrough an endoscope to permit visualization at the end thereof to facilitate placement of the endotracheal tube, the apparatus also including structure for providing controlled suction at the end of the obturator element.
Abstract: A skin care composition to prevent premature photoaging of the skin of the user includes in addition to basic ingredients, in combination, retinol, a UV absorber and a moisturizer.
Abstract: An ultrasonic toothbrush for use in personal dental hygiene care includes an exchangeable toothbrush member which is removably attached to an ultrasonic power member and may be readily removed therefrom with less than one revolution and inserted on to the ultrasonic power member in a like manner. Provision is made for locking the toothbrush to the power member and is arranged to transfer the ultrasonic energy from the power member to the toothbrush with minimum energy loss.
Abstract: An apparatus for maintaining and inspecting a dockside container crane includes a framework and a base for supporting thereon a rotatable turret having a telescopic boom and platform member. The base and framework is removably attachable to a standard ISO container, and once attached the ISO container may then be raised by the dockside container crane, via a standard spreader, where an inspector or workman manipulates controls on the platform member to operate the turret and telescopic boom, to position the platform member near a portion of the crane requiring inspection or service.
Abstract: A seamless filter bag having a removable, reusable ring includes a heat sealed filter bag open on one end adapted to receive a removable ring therein. Openings are provided in the filter bag which receive inwardly extending protrusions on the ring thereby maintaining the integrity of the filter bag material. A handle adapted to be received by the inwardly extending protrusions on the filter ring permits the removal of the filter bag together with the ring and any material retained in the bag from a conventional filter basket.
Abstract: A flexible boot adapted to receive a telphone cable plug includes an opening through which a telephone retaining lever projects. The boot receives the telephone cable through an opening provided therein and slips over the telephone plug. Upon insertion of the plug into a mating telephone jack, the boot frictionally engages the jack circumference and seals the connections from the environment. A similar boot may be utilized to protect and seal a telephone jack.
Abstract: A rare earth magnet article of the Fe-B type is provided herein characterized by consisting essentially of the three rare earth elements Nd-Pr-Ce in combination within defined atom ratios of each in the formula:(Nd.sub.1-(p+q) Pr.sub.p Ce.sub.q).sub.x B.sub.y Fe.sub.1-(x+y)wherein 0.1.ltoreq.x.ltoreq.0.3, 0.02.ltoreq.y.ltoreq.0.09, 0.1.ltoreq.p.ltoreq.0.3 and 0.02.ltoreq.q.ltoreq.0.15.The magnet is prepared by a process which assures that the resultant magnet has a coercive force, Hc, of at least about 5kOe, and a residual magnetic flux density, Br, of at least about 10kG, which magnetic properties are substantially the same within the range of the sintering temperatures of the process.
