Title: Improvements in or relating to galvanic batteries
IPC: H01M6/30
Filed: 1923-06-27
Abstract: 220,763. Fuller's United Electric Works, Ltd., and Fuller, L. June 27, 1923. Cases; cells.-To prevent local action in a dry cell during storage, the electrolyte salts e are stored in a separate enclosure a which also contains a sealing compound f and washer d. The materials are contained in compartments formed by partitions g in the enclosure a which may be constructed to fit over the cell b and which may be graduated to indicate the amount of water and other substances to be added when the cell is required for use. To activate the cell the enclosure a is removed and the electrolyte salts poured into the cell and water added. A layer f<1> of the sealing compound is then placed on the top of the electrolyte and the washer d placed over the central electrode as shown in Fig. 2, the remainder of the sealing compound f<11> being placed above the washer d. The washer d is shaped to leave an air space h above the layer f<1>. The sealing compound may consist of plaster of paris in which case water is added to the layer f<11> to complete the sealing. The layer f<1> absorbs a certain quantity of the electrolyte and assists the sealing.

Abstract: 877,878. Centrifugal pumps. GIRDLESTONE PUMPS Ltd. May 28, 1959 [June 3, 1958], No. 17706/58. Class 110 (1). In a self-priming centrifugal pump 1 having an impeller chamber 6 formed integrally with a coaxially disposed impeller bearing housing 7 of less radial dimension, an integral reservoir 9 for priming liquid is located at least in part beneath the said bearing housing and a port 13 is arranged to afford communication between the impeller chamber and the reservoir so that during priming liquid is directed on to the periphery of the impeller which is provided with a series of interruptions or irregularities 15 to increase turbulence on priming. The reservoir 9 extends upwardly as at 9a around the portion 6a of the impeller chamber 6 and, is connected to the impeller chamber by the port 13. In operation, liquid is drawn from the reservoir 9 through port 13 and is expelled by the impeller through upper port 12 back to the reservoir. Thus air is removed from the impeller chamber, creating a suction which draws liquid, from inlet 5, to the pump which then functions normally. When the pump is stopped sufficient liquid is retained in the reservoir to prime the pump when next started.
