Abstract:
A battery system includes a battery with a pair of terminals extending from one side of the battery case, and a tray-like battery holder. The terminals have hollow sockets inserted therein which are engaged by posts extending from conductive plugs that extend through an end wall of the holder. A threaded connection is formed in the plug and opens to the outside of the holder. Alignment posts are formed in the holder to be disposed within cylindrical wells in the bottom of the battery case and ensure proper alignment of the battery in the holder. A hinged latch is formed in the holder and engages a projection on the battery case. When in place in the holder, the battery case rests on resilient pads located on a floor of the holder.

A method and apparatus for injection molding of high quality thermoplastic parts is such that a conventional movable mold half is mounted on a movable platen of the injection molding machine, and a special stationary mold half is mounted on the stationary platen. The stationary mold half includes a stationary plate secured to the stationary platen, with the stationary plate including stationary mold inserts. Each stationary mold insert has a stationary mold insert surface. An A-half parting line plate is movably attached to the stationary plate, with the A-half parting line plate being movable with respect to the stationary plate and the stationary mold inserts. A driving device, such as a hydraulic cylinder, is disposed between the stationary plate and the A-half parting line plate, with the driving device driving the A-half parting line plate toward and away from the stationary plate. A control circuit is provided for controlling the driving device to control a movement of the A-half parting line plate with respect to the stationary plate.
Abstract:
The present invention teaches a variety of methods and systems for providing computer/human interfaces. According to one method, the user interfaces with an electronic device such as a computer system by engaging a sensor with desired regions of an encoded physical medium. The encoded physical medium is preferably chosen to provide intuitive meaning to the user, and is thus an improved metaphor for interfacing with the computer system. Suitable examples of the encoded physical medium include a data-linked book, magazine, globe, or article of clothing. Some or all of the selected regions have had certain information encoded therein, information suitable for interfacing and controlling the computer system. When the user engages the sensor with a region having certain encoded information, the certain encoded information is interpreted and an appropriate action taken. For example, the sensor or the computer system may provide suitable feedback to the user. The encoded physical medium may have text and/or graphic illustrations that draw the user in or provide meaningful clues or instructions perhaps related to the encoded information. The sensor may have at least one identification number (ID) providing information such as user identity, sensor type, access type, or language type. The sensor can transmit the certain decoded information together with the at least one ID to the computer system.
Abstract:
A battery shield for a storage battery includes first and second members which are dimensioned to fit around the battery, forming a shield structure, that is open at its top and encloses the battery on all four sides and on the bottom, forming a heat shield for protecting the battery from hot temperatures, the first and second members being hinged to a common base and are adapted to be pivoted about respective hinges outwardly away from another to an open position to facilitate installation of a battery in the shield and to then be moved upwardly and toward one another, in the manner of a "clamshell", to a closed position for enclosing the battery within the battery shield, the bottom of the storage battery having a plurality of transverse channels therein extending between opposing sides for permitting air flow around the bottom of the storage battery when the battery is enclosed within the battery shield.

An anti-theft battery system for vehicles includes a control circuit which is connected in the starting circuit and responds to a starting current which exceeds a set point value to interrupt the starting circuit, thereby disconnecting the starter motor from the battery preventing starting of the vehicle, a reset circuit responsive to the control circuit which resets the control circuit after a delay interval to permit the starter motor to be connected to the vehicle battery, and an override circuit for generating an override signal for overriding the control circuit for a preselected interval of time to permit an authorized operator to start the vehicle, the override circuit including a small portable transmitter adapted to be carried by the vehicle operator and a receiver connected to the control circuit.
Abstract:
The invention provides a vehicle battery system including a main and a reserve battery disposed within a battery housing (10) having conventional external dimensions and battery terminal locations. An illustrated embodiment includes a main battery, comprising a series of thin, flat cells (38) disposed along a first axis, and a reserve battery, comprising a series of cells (42) disposed along a second axis transverse to the first axis. An electrical circuit facilitates selective communication between the reserve battery and the vehicle starter in accordance with the position of a switch assembly (100). An electrically conductive fastener is disposed to simultaneously maintain electrical communication between a main battery termination and an external battery terminal and also between a reserve battery termination and the same external battery terminal.
Abstract:
The present invention relates to a unique battery arrangement including battery plates having a pair of spaced apart battery lugs for both the positive and negative plates. While being spaced apart, the lugs are located generally adjacent one top edge of the plates; on opposite sides for the positive and negative plate constructions. The straps used to electrically connect the lugs are lower in height than those used on current battery designs, providing excellent current collection, efficient fusion with smaller lugs and resistance to vibration caused by separation of the lugs from the straps. The present invention also features plates having greater plate surface area, improved current carrying capability and reduced voltage drop. A weld element couples straps of like polarity, and in the preferred embodiment, at least a portion of the weld element is located intermediate the ends of the straps.
Abstract:
To obtain tumor-selective, photosensitizing drugs useful in the localization of neoplastic tissue and treatment of abnormal neoplastic tissue such as tumors, one of two methods is used. In the first method, a hydrolyzed mixture of the products of reaction of hematoporphyrin with acetic acid and sulfuric acid is cycled through a microporous membrane system to exclude low molecular weight products. In the second method, drugs are synthesized or derived from other pyrrole compounds. The drugs (1) include two covalently bound groups, each with four rings, some of which are pyrroles such as phlorins, porphyrins, chlorins, substituted pyrroles, substituted chlorins or substituted phlorins, each group being arranged in a ring structure, connected covalently to another group and have a triplet energy state above 37.5 kilocalories per mole; (2) are soluble in water, forming an aggregate of over 10,000 molecular weight in water and have an affinity for each other compared to serum protein such that 10 to 100 percent remain self aggregated in serum protein; and (3) are lipophyllic and able to disaggregate and attach to cell plasma, nuclear membrane, mitochondria, lysosomes and tissue. The drug obtained by the first method has an empirical formula of approximately C.sub.68 H.sub.70 N.sub.8 O.sub.11 or C.sub.68 H.sub.66 N.sub.8 O.sub.11 Na.sub.4. Neoplastic tissue retains the drug after it has cleared normal tissues and illumination results in necrosis. Moreover, other photosensitizing materials may be combined with a carrier that enters undesirable tissues and cells of the reticular endothelial system such as macrophages. These photosensitizing materials: (1) must have a triplet energy state above 3.5 kilocalories per mole; (2) cannot be easily oxidized; and (3) not physically quench any required energy state. Preferably, this photosensitizing material should be lipophlic.
