Title: Improvements in or relating to electrode constructions for galvanic batteries
IPC: H01M6/12
Filed: 1954-09-27
Abstract: 801,204. Batteries. HYSING, E. G., and GRUSELL, A. E. Sept. 27, 1954 [Sept. 25, 1953], No. 27773/54. Class 53. The elements of a dry cell comprise a foil-like cathode 1 of a metal oxide, graphite and fibrous material to which is attached a metal layer 3 having a terminal wire 4. On the other side of the cathode is a paper sheet 2 impregnated with electrolyte and attached to an anode 5 of zinc having a terminal wire 6. The four layers are pressed together to form a single unit. The cathode may consist of oxide of copper, mercury, manganese, tungsten, molybdenum, &c., mixed with graphite and linen fibres, formed into a foil and metallized on one side with copper or iron by means of a gun. The sheet 2 is metallized on one side with zinc, and the non-metallized sides of the two foils are rolled or pressed together and impregnated with a solution of potassium hydroxide or ammonium chloride. Alternatively the unmetallized foil of oxide, graphite and fibrous material and the sheet paper may be made to adhere together, and the metal films then applied to the exposed surfaces. In another method the anode metal is applied in the form of powder or flakes to the damp paper sheet which is then pressed and dried. In a further method the anode consists of wire netting or of wires which are baked into one side of the sheet, or a metal foil may be provided with a rough surface or small barbs to make it adhere to the paper sheet. The dry electrolyte may be introduced into the paper during its manufacture, or the paper may be soaked in a solution of the electrolyte and dried. The combined electrodes and paper separator may be embedded in plastic material in which a channel is provided through which water may be introduced when the cell is required for use. The completed unit may be wound in a spiral.

Filed: 1935-10-16
Abstract: 465,946. Automatic control systems. LEA RECORDER CO., Ltd., and HORNER, J. W. Oct. 16, 1935, No. 28533. [Class 38 (iv)] [Also in Group XXI] Fluid level.-In mechanism for limiting the maximum flow of fluid in a channel or other passage, comprising a penstock or valve operated by a reversible electric motor and control means for the motor operated by the flow, a periodic or time switch is associated with the control circuits so that the control is only operative at and for predetermined intervals of time. As applied to sewage disposal works, an indicator or recorder c, operated by a float d, is associated with a weir b in a channel a, and a separating or storm weir e. Between the weirs band e is a penstock f raised and lowered by a reversible electric motor f controlled by the indicator c so as to maintain the water level at the float nearly constant. The float operates a two way mercury switch g which closes one or other of the circuits to the motor f<1> to raise or lower the penstock. In these circuits are an up limit switch h and a down limit switch i respectively, controlled by the penstock. A periodic or time switch j is located in the common return lead which closes the circuit at definite intervals, e.g. three minutes, for short periods of a few seconds, and thus allows the motor to operate only at intervals.
