Abstract: A grab bar or other accessory is attached to a wall with at least one anchor assembly. The anchor assembly can be removed and repeatedly used as needed. The anchor assembly includes a vertical support beam, an arm having a hub portion and an arm portion, and a mounting plate that is supported by the arm. The arm portion is received within a slot formed within the vertical support beam. A spring is attached to the vertical support beam and cooperates with the arm portion to hold the arm in place during installation. The mounting plate includes a plurality of hole locations spaced radially outwardly from a center opening. The mounting plate is rotatable to position the plurality of hole locations at one of many different desired mount positions for a variety of grab bars.

Abstract: A bar that is to be attached to a wall includes two stanchions, each stanchion supporting a portion of an elongated piece that extends from one stanchion to the other. A supporting connector having a lower portion attaches to and extends upwardly from each of the stanchions and a portion above the lower portion. A horizontal support extends horizontally from the portion above the lower portion of the connector between the stanchions and is disposed a distance D1 above each the stanchion. And, an adhesive is disposed beneath and attaches to the horizontal support and extends along a length thereof.

Abstract: Methods and apparatus for stacking predetermined sheets of various intermixed sizes in a stacking location by advancement of stacking devices into that location, selectively guide further sheets past the stacking location. That guiding of further sheets past the stacking location is mechanically slaved to the advancement of the stacking devices into the stacking location. Where the stacking devices are withdrawn from the stacking location preparatory to each stacking of a predetermined sheet, the guiding of that predetermined sheet into the stacking location is mechanically slaved to such withdrawal of the stacking devices. Where the sheets are stacked against a movable wall, an unobstructed space for receiving each sheet guided to the stacking location is permanently preserved between the movable wall and the withdrawn stacking devices.

Abstract: A bus system architecture and method provides on a substrate a bus line system for first and second circuit boards designed to extend across the substrate. Individually dedicated first, second and third bus lines for the first circuit boards are provided in a first bus line array at one side of the substrate. Individually dedicated fourth, fifth and sixth bus lines for the second circuit boards corresponding, respectively, to the first, second and third bus lines, are provided in a second bus line array representing a mirror image of the first bus line array at an opposite side of the substrate. An area of the substrate between the first and second bus line arrays may be subdivided into sequential first and second regions adjacent the first bus line array, and sequential third and forth regions adjacent the second bus line array. A third bus line array is located in the first region for the first circuit board, and a fourth bus line array in the fourth region for the second circuit boards.

Abstract: Methods of a human operator processing first and second interrelated documents in pairs relative to a processing station provide a first document entry station for receiving a first document from the human operator, and a second document entry station for receiving a second document from the human operator. The human operator separates the interrelated first and second documents from each other and deposits the first document in the first document entry station while depositing the second document in the second document entry station. The deposited first document is transported from the first document entry station relative to the processing station, and the second document is transferred from the second to the first document entry station, for subsequent transport from such first station relative to the processing station.

Abstract: An apparatus for automatically connecting and disconnecting a battery backup supply senses when the potential of a main d.c. power supply drops below a first predetermined value, and in response thereto connects the battery backup supply to an electrical load. The apparatus also senses when the potential of the battery backup supply drops below a second predetermined value and in response thereto disconnects the battery backup supply from the electrical load.

Abstract: A modular ceiling system utilizing a plurality of stringers interlocked with one another to provide a high strength, non-warping suspended ceiling grid assembly. The T-shaped stringer employed in the grid assembly has a channel-shaped T-head designed to support acoustical ceiling tiles flush with the lower edge of the stringers. The main stringers are arranged parallel to one another and interlocked to secondary stringers to provide a grid of four sided cells. Part of the secondary stringers have the same length as one side of a single cell and others are of double that length. The double length secondary stringers are constructed to have a snug snap-lock joint with the main stringers whereas the single length secondary stringers have a snug, non-locking fit between the mid-portions of the double length stringers.

Abstract: A temperature compensation circuit for sensors of physical variables, such as temperature and pressure, employs an effective constant current source that is sensitive to ambient temperature and which has an adjustable thermal slope and an adjustable output at discrete temperatures. The effective constant current source may be connected across the input terminals of a sensor such as a pressure transducer employing strain gages or it may be connected in series with the excitation current of such a transducer. Additionally, the effective constant current source may be connected in the output of a sensor such as a thermocouple that is responsive to temperature changes. When connected to the input of a sensor, the temperature compensation circuit controls the excitation current through the sensor as a function of the ambient temperature of the sensor and compensation circuit.
