Abstract: METHOD FOR PREPARING LEAD-ACID BATTERY PLATES ABSTRACT     Lead-acid battery plates are made by preparing alloys of lead with at least one additive metal that can be leached with an acid or an alkali from the alloy leaving a porous permeable lead matrix.  The additive metal must be evenly and finely dispersed in the lead.  A number of additive metals can be used but the additive metal is preferably magnesium or zinc and magnesium, each in a preferred amount in the range of about 3 to 15% by weight.   The lead alloy is prepared by casting,  preferably by  rapid  solidification casting,  and subsequently pulverizing the alloy.  The resulting lead alloy particles are applied to a conventional lead alloy battery grid by pressing, causing the formation of a coherent plate of grid and alloy.  The plate is subsequently leached in an alkali or an acid which causes the substantial removal of additive metal  from the alloy  leaving a coherent porous permeable layer of substantially lead as active material.  The preferred leachant is sulfuric acid.  Other leachants require careful removal of all traces from the lead matrix.   The plates are used for both the positive and the negative plates.          The negative plates are treated with an expander, preferably by vacuum impregnation.  The positive and negative plates are assembled into a battery which is filled with electrolyte and charged.  The fabrication time is reduced from 5 to 7 days for prior art batteries to about 1 to 2 days.

Filed: 1990-12-24
Abstract: ABSTRACT      With a device used to carry any material manually, the device either has handles which are situated close to the material being carried, or a frame on which the material is placed, and then moved.          With the first system, the use of the handles forces the user to bend over to start the lift process.The frame unit is bulky and hard to handle in tight quarters. In this invention the device utilizes a shoulder strap fastened to the appropriatly shaped bracket, chain, cable, or strap, and then extends down the opposite side of the body to the desired height. When used properly, this invention allows the user to suspend the load by simply straightening their legs, and to carry the load with the act of walking.

Filed: 1991-03-08
Abstract: ABSTRACT OF THE DISCLOSURE      An apparatus for producing items in selected configurations and a system and method for controlling the same.  More particularly, an apparatus for producing mail pieces and a system and method for controlling it to produce mail pieces in a variety of configurations are disclosed. The apparatus includes a laser printer and folding sealing apparatus controlled by a data processor.  The folder sealer apparatus combines sheets printed by the laser printer with pre-printed sheets and envelope forms, which also may be printed by the laser printer or may be windowed envelopes, folds the sheets as necessary and folds and seals the envelope form about the folded sheets to produce a mail piece.  A user inputs a configuration for the mail piece which is translated by the data processor into a data structure and transmitted to the controller of the folder sealer apparatus.  The controller controls devices comprised in the laser printer and the folder sealer by executing state routines in accordance with the data structure to produce the mail piece in the defined configuration. Concurrently the data processor transmits text from an output file to the laser printer for printing on printed sheets and envelope forms.  The data processor also controls the laser printer to print an address for the mail piece either on an envelope form or on a printed sheet in a position where it will be visible through the envelope. Thus the apparatus is controlled to process an output file stored in the data processor into a mail run having a selected configuration.  A sheet feed for feeding sheets and envelope forms to the apparatus is also disclosed.

Abstract: A casement window wherein the sash is pivotable in the frame about a vertical axis has a self-locking crank drive which pivots the sash between open and closed positions by way of a pivotable lever, a link which is coupled to the lever, and an actuator which is movably installed in the sash, which is coupled to the link and which forms part of a locking-unlocking mechanism for the sash. The first stage of rotation of the crank drive in order to pivot the sash from closed position involves a displacement of the actuator which ensures that the sash is unlocked, and further rotation of the crank drive results in pivoting of the sash to the open position. If the direction of rotation of the crank drive is reversed, the sash is moved to the closed position before the actuator is caused to lock the sash to the frame. A blocking device for the actuator is operated by the frame to .release the actuator for movement to its operative position shortly before the sash reaches the closed position. To this end, a mobile blocking element of the blocking device is installed in the sash and is displaced by the frame before the sash reassumes its closed position whereby the blocking element releases the actuator which is held in the inoperative position while the sash is held in an open or partly open position.

The plating surface has a peak region and a base region separated and electrically isolated by an insulator. The peak region has a greater tendency toelectrodeposit the metal per unit surface area than the base region. The anode and cathode are placed in a test cell or suspended in a commercial electrodeposition cell. A means for applying current between said anode and said cathode is used for causing the metal from the electrolyte to electrodeposit on the plating surface of the cathode. The current from plating on the peak region and the base region are measured separately to determine levelling power of an electrolyte.
