Title: Improved apparatus for testing electric storage batteries
Inventor: HOXIE EARL ALFRED
IPC: G01R31/36
Filed: 1950-03-11
Abstract: 667,491. Battery testing apparatus. ELECTRIC STORAGE BATTERY CO. March 11, 1950, No. 6180/50. Class 37. Battery testing equipment designed to obviate the need for an ammeter or voltmeter utilizes a relay in series with and controlled by a variable resistance whereby the magnitude of the resistance in series with the relay at the point of actuation is indicative of cell voltage. In the apparatus shown 10 represents a battery to be given a cell condition test or comparison of cell discharge test. In each test the battery size selector 20 is set to give the appropriate test load. In the cell condition test the control arm and pointer 53 of battery temperature compensator rheostat 54 is set to the battery electrolyte temperature along scale 57 if the battery was " slow charged " and on scale 58 if " fast charged ". With the cell selector 37 set to the first cell 11 the control arm and pointer 63 of battery condition indicator rheostat 61 is moved from the extreme left to cut out resistance until the relay 48 is actuated as indicated by lighting of lamp 70. The condition of this cell, and cells 12 and 13 similarly tested, is shown by the appropriate marking on the top scale 62. In the comparison of cell discharge test the cell selector switch 37 is set to the first cell 11 and the pointer 63 of the battery charge indicator is set to 0 on the voltage scale 65. The control arm 53 of rheostat 54 is adjusted until relay 48 pulls in as seen at 70. For this test the rheostat 54 simply serves as a standard resistance, i.e. the temperature scales are ignored. The pointer 63 of the battery condition indicator 61 is rotated to the left to reset the relay. The cell selector switch 37 is moved to the second cell 12. The pointer 63 is now rotated to the right until the relay is again operated and the scale position for this is marked by the use of position marker 66. The relay is again de-energized. The cell selector switch is set to the third cell 13 and the relay again operated with pointer 63 in another definite position. The three positions along the scale 65 corresponding to the three cells are denoted by the pointer 63, the position marker 66 and 0. If these positions are within 0.15 volts of each other as indicated on scale 65 the battery has additional useful life. The load resistors 21- 25 and the control rheostats 54 and 61 are of material that has a substantially zero temperature coefficient. The resistors 50, 51 are so chosen as to balance out the positive temperature coefficient of the copper wire used in relay 48.

Abstract: 249.114. Trico Products Corporation, (Assignees of Oishei, J. R., and Hueber, H.). March 11, 1925, [Convention date]. Fixed-abutment type; starting and stopping; valves, distributing and cut-off.-A wind-sereen wiper C is operated by the oscillating-vane of a rotary engine A connected to the intake pipe of the vehicle engine or other source of suction I, by a valve 10. For operation, the pipe 11 from the suction member I is connected to the pipe H by the valve 10, Fig. 2. The pipe H is connected to a passage G in the engine, which in turn communicates with passages K, L which lead, via passages M, N, through valves O, P, to the working chamber E. The valve P is constructed with a slider R in a bushing Q recessed at S, Fig. 3, atmospheric air being admitted by the knurled part T. The valve 0 has no knurled part. The valve head P<1> fits closely in the bushing and can connect or interrupt the passage L, N or K, M. As the vane D, Fig. 6, oscillates, a rocker V actuated by a cam W on the rock-shaft F and a spring connector Y, cause the valves 0 and P to open and close alternately. To put the wiper out of action and prevent its slipping to a position in which it obscures fhe view of the driver, the valve 10 is moved to cut out the pipe H and put the pipes 11 and 17 into communication. The pipe H is then in communication with the atmosphere and the pipe 17 with the suction member I, causing the vane and wiper to move to the extreme left limit of their strokes and to remain there until the valve 10 is actuated to place the pipes A and 11 in communication.

Title: Production of chlorocyanuric acids
Filed: 1962-02-22
Abstract: A process for.producing a chlorocyanuric acid which comprises introducing chlorine into an aqueous alkaline dispersion of an alkaline earth metal salt of cyanuric acid at a temperature in the range from above the freezing point (-5 DEG  C.) of the dispersion, and continuing the addition of chlorine until the pH of the dispersion is reduced to a value below 4.  Preferably the temperature is at most 50 DEG  C.  The alkaline earth cyanurate may be prepared as a 10-30% slurry by mixing a 10-35% aqueous slurry of the alkaline earth carbonate, oxide or hydroxide with a 5-25% slurry of cyanuric acid in stoichiometric proportion, which mixture then has a pH of 12.0-12.6 and to which liquid or gaseous chlorine is added with agitation and external cooling to replace the metal atoms of the cyanurate.  The mixture is maintained at 10-35 DEG  C. and the chloro cyanuric acid separated, e.g. by centrifuging.  The process may be continuous, the chlorine and the slurry of cyanurate being introduced into the reaction zone at 0-50 DEG  C. at rates to adjust the pH to below 4 and a portion of the mixture is continuously removed from which the chloro cyanuric acid is separated.  Trichlorocyanuric acid is prepared from the trialkaline earth metal dicyanurate using 100-200% of the stoichiometric quantity of chlorine and reducing the pH below 3.5.  The dichlorocyanuric acid is prepared from the mono alkaline earth metal monocyanurate using 100-120% of the stoichiometric quantity of chlorine and reducing the pH below 2.5.
