Abstract: An enclosure for a rechargeable energy storage system (RESS) includes a hermetic sealing enclosure and a structural housing component configured to support the hermetic sealing enclosure. The hermetic sealing enclosure is arranged on the structural housing component. The hermetic sealing enclosure is configured to house the RESS and provide a hermetic seal.

Abstract: A preassembled cathodic protection system is provided for protecting buried structures such as guy anchors, which includes a reference cell, test station and anode, all prewired together and tested before delivery and field installation. The package includes a convenient connection for the structure which has one lead to an exposed stud or contact point on the test station, and another lead from the connection to the anode or anodes through a shunt in the form of a calibrated resistance wire. The shunt is connected to two spaced studs or contact points on the test station by which the shunt is read. The reference cell is also connected to a stud or contact point on the test station. The reference cell-test station lead extends through a flexible tube. The studs or contact points are on the dome or cap of a rigid tube designed to project out of the ground or an electrolyte a short distance. With a guy anchor the tube may include an elow and angled portion.

Abstract: An integrated cell and the test station is disclosed in a unitary package which includes internally encapsulated wiring connections at both the cell and test station. The cell and test station are tethered together by a flexible bungee tube which can be coiled and which can elongate or contract. The flexible tube provides a variable length and wide lateral flexibility. The tube also provides a convenient means to encapsulate the connections at both the cell and test station. The cell has a unique core formed by a double junction ceramic capsule. A pure copper coil element is positioned in the capsule in a super saturated solution of copper sulphate, for example. The capsule is sealed and the coil or element is electrically connected to a lead extending through the tube, and the end of the tube is encapsulated sealing the connection. The capsule is joined to one end of the bungee tube and the entire end is embedded in a stabilized hygroscopic gel which contains additional salt crystals.

Abstract: A wireless interactive consumer video system and a method for wireless communication between an input and display unit and a video electronics unit. The input and display unit includes a key pad and a video display. The input device accepts a user entry and generates a data signal corresponding to the user entry. The input and display unit transmits the data signal to the video electronics unit, which generates a video signal responsive to the data signal. The video signal is then provided to the input and display unit, which provides an image on the video display.

Abstract: An electrode is disclosed which is particularly useful as a reference electrode in cathodic protection systems. In any reference electrode or half cell, its continued stability is predominantly dependent on the metal ion concentration around it. In time such ions tend to leach away reducing the stability, effectiveness and life of the electrode. With the present invention such ions in the electrolyte may be replenished by the addition of a concentrated solution of metal salt to a ceramic canister which may include a glaze coating which may have one or more diffusion ports permitting the metal salt solution to leach at a controlled slow rate to the area surrounding the electrode ensuring continued stability and longer effective life for the electrode. The one or more diffusion ports also provide a low resistance current path to or from the lead within to the canister and the surrounding electrolyte.

Abstract: A promotional method comprising the steps of storing a predetermined number of recognizable data, storing a message for each of the predetermined number of recognizable data, scanning a document to read machine readable information appearing thereon, determining whether scanned data represented by the machine readable information on the scanned document represents data corresponding to any of said stored recognizable data, identifying the stored recognizable data corresponding to the scanned data in response to the determination that the scanned data corresponds to one of the stored recognizable data, identifying a stored message associated with the identified stored recognizable data, and selecting the identified message and producing an output response corresponding thereto.

Abstract: A comminuting apparatus uses a vacuum hose to draw fibrous vegetable matter, such as leaves, twigs or the like, into a shredder for disintegration. A flexible hose leads to a shredding chamber surrounding a rotating shaft to which whips are loosely attached. The whips are preferably made of stiff metal wire, but chains, knives or rods could be substituted therefor. The shaft is journalled within a bearing supported by radial struts attached to the inner wall of the cylindrical shredding chamber housing. A single fixed whip may be attached to the shaft outward from the struts for clearing leaves from the struts. The remainder of the whips are on the portion of the shaft inward of the bearing and struts.

Abstract: A data entry terminal for storing a plurality of user generated answers is described which includes a removable volatile read/write memory module. The memory module is used to store formatting information used to configure the data entry terminal as appropriate for a particular set of questions. The memory module can for example store a set of correct answers as well as a set of user answers for each of the questions of the test, and it can store data used to disable certain functions of the data entry terminal, such as the ability of a user to revise an initially entered answer. The data entry terminal operates to record user answers in the portable memory module, which can then be removed from the data entry terminal and applied as an input to an external computer for analyzing user responses. The portable memory module includes a battery for powering a volatile semiconductor memory included in the module.

Abstract: A teaching device includes a reading station provided with six on-off switches for automatically sensing a text key encoded as a pattern of punched holes in a text book. The teaching device automatically generates an answer key from the text key by means of a pseudo-random number generator which is run using the text key as a seed. The text book includes a number of multiple choice questions in which the correct answer corresponds to the answer designated in the answer key.

Abstract: An automatic note analyzer is disclosed which automatically generates and displays a note signal indicative of the musical note corresponding to an input signal. The disclosed analyzer operates to measure the period of the input signal on a regular basis. According to one aspect of the invention, the measured period is compared with a predetermined window representative of the expected value of the measured period. Measured periods which do not fall within the predetermined window are rejected. According to a second feature, measured signals representative of the period of the input signal are averaged in order to increase the stability of the analyzer. The disclosed analyzer operates in two modes: an absolute mode, and a transposer mode. In the absolute mode the displayed note value is determined with reference to an absolute pitch. In the transposer mode, the displayed note value is determined with reference to a relative pitch which can be readily adjusted as needed.
