Abstract: An improved vent cap system for use in an electrochemical battery is provided which includes a ring flange for forming a ring seal between the vent cap assembly and the fill tube. When the vent cap assembly is positioned in the battery housing, the ring flange and the fill tube deform to create a seal therebetween to provide a fluid tight seal.

Abstract: A split-shell enclosure for a storage battery for motor vehicle includes identical first and second enclosure members which are dimensioned to fit around the battery, forming a shell structure, that is open at its top and bottom and partially encloses the battery on two sides and completely encloses the battery on the other two sides, forming a heat shield for protecting the battery from hot underhood temperatures, the enclosure members being adapted to snap together upon installation and to be held together by interlocking tongue and groove portions of mating sides of the enclosure members, upper portions of the enclosure members being disposed in juxtaposed relation with the handle brackets of the battery so that if the battery is lifted by the enclosure, the enclosure members will engage the handle brackets of the battery and the battery will effectively be lifted by its handle brackets and no load will be placed on the latches that hold the two sections of the enclosure together, and lower portions of the

Abstract: An arrangement for mounting a battery monitoring circuit on the cover of the battery and for connecting the terminal ends of first and second lead wires of a battery monitoring circuit to the positive and negative terminals of the battery, the arrangement including a cavity formed in the battery cover for mounting the battery monitoring circuit, first and second battery terminal bushings which are molded integrally with the cover and are adapted to be mounted on and connected to the positive and negative battery terminals when the battery cover is installed on the battery, each of the battery terminal bushings including a pad having an upwardly directed mounting post that is adapted to receive and secure the terminal end of one of the lead wires of the battery monitoring circuit, the battery cover having first and second lead wire slots in its surface which extend from the cavity in which the battery monitoring circuit is mounted, to the locations of the battery terminal bushings for directing the lead wires

Abstract: A battery thermal control system including a casing for the battery and a cover for enclosing the battery in the casing, the casing being provided with a number of ribs for supporting the battery in a spaced relation to the bottom of the casing and to the side walls of the casing, a fan connected to discharge air into the casing for circulation through the spaces between the battery and the casing and a bypass duct for connecting the fan to a warm air source for heating the battery in the winter. A timer circuit is provided for continuing the operation of the fan after the engine is turned off. The timing circuit including a temperature switch for activating the timer circuit when the temperature is above a preset minimum.

Abstract: The manual portioning of non-uniform bulk products, such as the bagging of freshly prepared food products in fast-food restaurants, is controlled by a method and means which provide rapid and accurate individual portioning and consistently accurate feedback to the operator. Accurate real time weighing is provided quickly for every portion, and apparatus is disclosed to provide dynamic weighing such that no significant additional time is required for the portioning cycle. Since the feedback to the operator is based on true rather than estimated weight and is presented at the optimum time and location, the operator learns to portion the products accurately, as well as consistently.

Abstract: An electrolyte reservoir in fluid communication with the cell of a storage battery is intermittently pressurized with a pulse of compressed gas to cause a flow of electrolyte from the reservoir to the upper region of less dense electrolyte in the cell. Upon termination of the pressure pulse, more dense electrolyte is forced into the reservoir from the lower region of the cell by the differential pressure head between the cell and reservoir electrolyte levels. The compressed gas pulse is controlled to prevent the entry of gas from the reservoir into the cell.
