Abstract: A novel battery dumping apparatus is described which is uniquely suited for dumping corrosive substances, such as battery acid, simultaneously from a number of automotive batteries. The novel apparatus generally comprises a sealed tube adapted for rotation through an arc of less than 360 degrees. Within the tube are disposed two parallel spaced apart baffles which together form a sealed battery processing channel. This battery processing channel is pierced by a plurality of rods disposed in a plane which bisects the aforementioned baffles. These rods are ultimately caused to rotate in opposite directions by a gear drive disposed outside of said battery processing channel but within said tubular member. These gears are, in turn, caused to drive said rods by a pneumatic motor which is mounted outside of said tubular member.

Abstract: A method for automatically installing covers on industrial lead-acid battery cells including the steps of placing cell groups within a cell jar, then automatically straightening the posts of the group. The cover is then placed on the jar containing the group, the cover is sealed to the jar, and the excess flash, which may have been produced during the cover sealing operation, is removed. Next, the posts are welded to bushings mounted in the cover. The sealed cell is then tested to insure that no leaks are present. Those cells passing the seal test will be passed on for further assembly operations while those cells which do not pass the seal test will be automatically shunted aside for subsequent manual inspection and rework where possible. The apparatus comprises a series of interlocked and interrelated conveyors, accumulators and pinchstop mechanisms which automatically convey the cells being sealed to machines which perform the operations delineated in the aforementioned method in the proper sequence.

Abstract: A novel coronary dilation method is disclosed wherein a guiding catheter having at least one side arm is continuously flushed with heparinized saline during the dilation process except for momentary interruptions for recording coronary pressures. In accordance with the preferred embodiment method, a dilating catheter (of a balloon-type) is inserted with the guiding catheter and is also continuously flushed through an inner lumen except for periodic pauses to record coronary pressures. A stylet having a thickness substantially thinner than the inner lumen of the dilating catheter is inserted therein, which stylet terminates 3 to 5 mm. short of the end of the catheter. The outer lumen of the dilating catheter is utilized to inject dye and saline for inflating the balloon to perform the coronary dilation.

Abstract: An automatic tumble dumper for automatically removing the electrolyte from lead-acid storage batteries and particularly batteries intended for automotive use is disclosed. The device comprises carrier means adapted to transport the batteries through the system. Once the batteries are inside the unit, upset means automatically turn them first onto their side and then invert them so that the bulk of the electrolyte passively drains out. To achieve complete electrolyte removal, the batteries are jostled via a jostling means which cooperates with said carrier to actively shake the batteries as they travel through the device. At the conclusion of this shaking, now drained batteries are returned to an upright position and travel out of the machine for further processing.
