PURPOSE:To enable a battery to be more easily charged after it is left in an overdischarged state by drying positive plates immersed in an acidic solution at low temperature and in a short time. CONSTITUTION:Positive plates immersed in dilute sulfuric acid after formational charging, are washed with water before being dried under reduced pressure at 100 deg.C. The drying is completed within 2hr be...

PURPOSE:To decrease the required frequency of water supply and enable stirring of electrolyte to be easily performed by using a lead alloy having a low hydrogen production potential as part of the current collectors of negative plates. CONSTITUTION:A lead alloy containing 0.1% of Ca and having a high hydrogen production potential is used as current collectors for positive and negative plates. In s...

PURPOSE:To secure close contact between plates and retainers by packing a paste into a grid, applying retainers to the surfaces of the packed grid immediately after, then subjecting the thus obtained body to drying and ageing. CONSTITUTION:After retainers 3 are affixed to the surfaces of a positive plate 2 packed with a paste by means of a packing machine 1, this is pressed by being sent through p...

PURPOSE:To enable the pressure control of a plate group to be easily performed by using retainers made thin by pressing. CONSTITUTION:After the thickness of retainers is decreased by pressing, they are interposed between positive and negative plates to make a plate group. The decrease in the pressure of the pressed retainers caused after electrolyte pouring is 1/2-1/3 of that of nonpressed ones. A...

The invention relates to a process and an apparatus for the more economical production of twisted yarns by the double-twist method. The feed bobbin used is a parallel-wound shed bobbin, having a length/diameter ratio of more than 2.5, which narrows in its upper part and the volume of which is the best possible in accordance with the yarn number and twist. The spindle rotor of the twisting machine ...

A weighing system is disclosed which operates in conjunction with a scale that has a trigger mechanism for terminating the flow of material into the scale's bucket. This system automatically periodically revises a tare signal stored in a latch circuit for combination with a weight signal to produce a net weight signal. The tare signal provides a measure of the residue stuck in the scale bucket. In...

A tire building drum is described as having a unique mechanism for controlling the radial movement of the bead lock segments which are designed to hold the tire bead rings firmly, in position, during the tune-up operation. The mechanism includes an annular support member which is disposed concentrically around the longitudinal center axis of the drum adjacent opposing ends of the drum, and which h...
