Abstract: A multi-axis roll-forming system for forming a stepped diameter in a cylinder includes a support that spins about a rotation axis while supporting a workpiece that includes the cylinder. A first actuator translates a first roller perpendicularly to the rotation axis. A second actuator moves a multi-axis roller radially outward, relative to the rotation axis, and upward along the rotation axis. The system may also include a first roller arm to which the multi-axis roller is coupled. The first roller arm is connected to a pivot joint having a pivot axis that is perpendicular to the rotation axis. The second actuator may include a linear-drive actuator that is coupled to the first roller arm and extends along the rotation axis to force the multi-axis roller to pivot about the pivot axis.

Abstract: A multi-axis roll-forming system for forming a stepped diameter in a cylinder. The system includes a support configured to spin about a rotation axis while supporting a workpiece including a cylinder. A first actuator is configured to translate a first roller perpendicular to rotation axis. The first roller includes a truncated conical work surface configured to press against the inward-facing surface of the cylinder to angle it outward according to a slant angle of the truncated conical work surface.

Abstract: A multi-axis roll-forming method includes simultaneously (a) spinning, about a rotation axis, a spin platter having placed thereon a ring encircling the rotation axis, (b) pressing at least one first roller against outward-facing surface of a first portion of the ring to press the first portion against an outward-facing surface of the spin platter, and (c) forcing a second roller against an outward-facing surface of a second portion of the ring to bend toward the rotation axis the second portion, so as to form a lip extending toward the rotation axis, wherein the step of forcing includes (i) pivoting the second roller against the second portion, and (ii) translating the second roller along the second portion toward the rotation axis.

Abstract: A roll-forming manufacturing method of a roller bearing seal case includes (a) roll-forming, from a cylindrical ring, a first profiled ring having a first section extending along cylinder axis of the cylindrical ring and a second section extending from the first section inward toward the cylinder axis, (b) applying outward pressure to the first section, in direction away from the cylinder axis, to round the first section, and (c) roll-forming a second profiled ring from the first profiled ring.

Abstract: In order to permit use of a refrigerator by observant Jews during Holiday times, Normal and Holiday modes are established. During Holiday mode, repetitive fixed frequency and fixed duty cycle time cycles are established, each time cycle having “on” and “off” portions. During “on” cycle portions current flow through the refrigerator is permitted as determined by the refrigerator compartment temperature. During “off” cycle portions current flow is inhibited irrespective of refrigerator compartment temperature changes. Visible indicators inform users of the status of the current cycle portion, thereby advising them to open the refrigerator door only during “off” cycle portions.

Abstract: A surgical illumination device includes a LED with a positive terminal, a negative terminal, and a heat transfer pad. A flexible circuit has first and second electrically conductive traces extending from a proximal end to a distal end thereof. The first conductive trace is electrically interconnected with the positive terminal, the second conductive trace is electrically interconnected with the negative terminal, and a heat transfer window on the flexible circuit is aligned with the heat transfer pad. The illumination device includes a heat sink having a distal end with a distal end face. A thermally conductive adhesive pad is disposed between the LED and the distal end face of the heat sink. The thermally conductive adhesive pad is aligned with the heat transfer window of the flexible circuit and the heat transfer pad of the LED base.

Abstract: Techniques are provided for inhibiting changes in the operational state of electrical circuits for lights, appliances and other devices by controlling the effect of manual actuation of an electrical switch in an electrical circuit. A normal mode is established in which manual actuation of the switch effects a change in a state of current flow in the circuit. An alternative holiday mode is also established in which manual actuation of the switch has no effect on current flow in the circuit. Automatic switching occurs between the normal mode and the holiday mode at specific times corresponding to specific events dependent on the time of year, a time of day and a geographic location of the circuit.
