Abstract: Apparatus which is capable of providing efficient cooling of rack mounted electronic modules while accommodating relatively large tolerances in the mounting of the modules. A plurality of thermally conductive sliding wedge blocks are interposed between the lower surface of each module and the upper surface of the cold plate base of the rack. The mechanism for clamping a module to the rack also pulls the wedge blocks together to fill in the gap between the lower surface of the module and the upper surface of the cold plate so as to provide a complete thermal path therebetween.

Abstract: A method and apparatus for determining to which battery cell in a string of battery cells between a pair of busses a test instrument is connected. Knowing the average voltage of the battery cells in the string, the voltage from one of the busses to the side furthest from that bus of the cell of interest is measured, and that measured voltage is compared with a voltage range calculated as a multiple of the average voltage.

Abstract: A rain gutter roll forming machine wherein the final forming station has the exit drive rollers removed therefrom. The forming rollers for the lower front and back corners of the gutter are mounted for rotation about a single substantially horizontal axis and are supported by a camber adjustment plate. The camber adjustment plate is pivotable about a pivot point which is substantially within the plane of the bottom wall of the gutter. Accordingly, the relative pressures applied to the gutter by the corner forming rollers can be varied to compensate for longitudinal curvature of the gutter due to differential drag on the front and back gutter walls.

The liners extend through an open slot in the top of the box and the innermost liner of the roll is securely attached to a cylindrical spindle on which the liners are wound. The dispenser also includes a reinforcing insert in the form of a piece of sheet stock in a U-shape partially surrounding the roll of liners. The box is detachably secured to the bottom of the trash container and the spindle is dimensioned so as not to pass through the slot. Accordingly, when the last liner in the box is used and removed from the container, the box is removed as well.

Abstract: A shear assembly for a roll forming machine which forms a rain gutter. A pair of coplanar blade members separated along a vertical line are caused to first move vertically downwardly, then have their lower ends pivot outwardly and, finally, have their upper ends pivot outwardly. The last motion is accomplished with enhanced mechanical advantage to cut through multiple layers of metal at the upper end of the gutter.

Abstract: A filter wherein the poles and zeroes are programmable in a high speed control loop to form a particular desired filter profile. The control loop retrains the filter's poles and zeroes during the “off” time between the reception or transmission time slots. Desired pole and zero frequencies are injected and peak values are stored in sample and hold circuits. This eliminates variations from voltage supplies, component tolerance, temperature, aging, etc.

Abstract: A probe assembly for use with a battery impedance meter which minimizes excitation pick-up voltages by routing the wires from the meter to the battery cell terminals without forming a loop within a changing magnetic field caused by current drawn from the battery cell.

Abstract: A roll forming machine wherein a single operator can quickly replace roll forming stations to change the desired lateral profile and wherein adjustments to the lateral positions of the roll forming stations can be quickly effected. This is accomplished by mounting the roll forming elements on short tooling rail sections which in turn are mounted on longer mounting rails which are used as platforms whereby all the adjustments are preset so that all setup work is performed prior to installing the tooling rails. Because the tooling rail sections are shorter, they may be inserted in, and removed from, the machine by a single operator without requiring the partial disassembly, and subsequent reassembly, of the entry and shear assemblies.

Abstract: A roll forming machine for a debris shedding rain gutter having a lower trough and an upper hood, wherein independent adjustments are made to the front wall of the trough to insure that its upper edge is behind the forward end of the trough. An independently adjustable kick forming station is provided to create an inward bend near the upper end of the front wall. A block is adjustably mounted to a cross-member of the machine to press the front wall inwardly to insure that the angle where the front wall joins the bottom wall of the trough is approximately ninety degrees.

Abstract: A lifting toilet chair having arm rests which are utilized to provide a leveraging action to allow the user to control the ascent and descent of a pivoting toilet seat as well as to assist the user in raising himself/herself from a sitting to a standing posture.

Abstract: A method for determining the internal impedance of each battery cell within a system including at least one parallel string of serially connected battery cells without disconnecting the battery cells from the system, which initially makes measurements of two battery cells within each string to calculate the internal impedance of each of those two battery cells and to calculate a common impedance multiplier term for the rest of the battery cells in each string. The remaining battery cells in each string are individually measured and the common impedance multiplier term for that string is used to account for measured current which comes from the Thevenin equivalent voltage source of the rest of the system, in addition to current drawn from the battery cell being measured.

Abstract: A collar for a connection between a resilient tube and a rigid barbed connector. The collar comprises a generally cylindrical sleeve member having interior annular ridges. When the collar is installed on the tube surrounding the barbed connector, the ridges press into the tube and prevent expansion of the tube to prevent leakage between the tube and the connector.
