US Patent:

41373774, Jan 30, 1979

Filed:

Oct 19, 1977

Appl. No.:

5/843470

Inventors:

Donald H. McClelland - Littleton CO

Assignee:

The Gates Rubber Company - Denver CO

International Classification:

H01M 214

US Classification:

429145

Abstract:

A rechargeable maintenance-free normally sealed lead-acid cell is disclosed having a multilayered electrolyte-retaining separator composed of outer highly porous and compressible microdiameter glass fibrous layers, which contact the positive and negative plates, and a sandwiched substantially dimensionally stable microporous layer having, compared with the glass fibrous layers, a substantially higher resistivity and lesser thickness. The electrolyte is proportioned within the cell and separator so that the bulk of the electrolyte in the cell is contained within the pores of the multilayered separator, and distributed between the layers of the separator in a preferred manner.

Appl. No.:

5/733674

Inventors:

Leonard F. Hug - Wheatridge CO
Donald H. McClelland - Littleton CO
Toshio Uba - Denver CO

Assignee:

The Gates Rubber Company - Denver CO

International Classification:

B21C 4712

US Classification:

72147

Abstract:

A spirally wound element comprising opposite polarity plates and interleaved separator is described, for use in electrochemical cylindrically configured cells. The cell pack has a uniform predetermined cross section irrespective of variation in component thicknesses as long as such thicknesses are within specified tolerances. Dual head, belt-driven winder and method are also described for producing the spiral cell pack.

Filed:

Apr 23, 1974

Appl. No.:

5/463225

Inventors:

Herbert G. Pankow - Littleton CO
Terrance M. Larkin - Littleton CO
Roland L. Young - Denver CO
Donald H. McClelland - Littleton CO

Assignee:

The Gates Rubber Company - Denver CO

International Classification:

H01M 3526

US Classification:

136 67

Abstract:

Method and apparatus are taught for applying an electrochemically active thixotropic paste onto a porous substrate. A discharge means such as a nozzle is used to deliver a predetermined amount of the paste onto the moving substrate which then enters the nip of a set of opposed driven rolls of desired spacing which compresses the paste into the interstices of the pores of the substrate to produce the desired plate.

Filed:

Dec 29, 1980

Appl. No.:

6/221226

Inventors:

Donald H. McClelland - Littleton CO
Toshio Uba - Denver CO
Larry K. W. Ching - Littleton CO

Assignee:

The Gates Rubber Company - Denver CO

International Classification:

H01M 1012

US Classification:

429 54

Abstract:

A recombining lead-acid battery with absorbed electrolyte is disclosed having multiple cells positioned in a sealed monobloc container, and cell partitioning members constructed to define a gas space common to all the cells of the battery. When the battery is overcharged imbalance in electrolyte fill among the cells is reduced as the amount of water in each cell tends to equalize through redistribution via gas recombination preferentially in the drier cells.

Assignee:

Cover-Pools, Inc. - Salt Lake City UT

International Classification:

C04H 319

US Classification:

4502

Abstract:

A swimming pool cover apparatus is described whereby the pool cover may be extended and retracted through a power source. The apparatus includes a drive shaft circumscribed by a pair of sleeves. Each of the sleeves may be selectively rotated through a double-dog clutch system connected to the drive shaft. A cover-collecting drum is connected to one of the sleeves. A pair of cord-collecting reels rotatably circumscribe the other sleeve. Controlled rotation of the two cord-collecting reels is achieved through a ratchet and spring-biased pawl system. This system also permits slippage of either of the two cord-collecting reels when the tension on either one of the reels becomes excessive.
