Title: Improvements in electromagnetic relays
IPC: H01H50/88
Filed: 1946-08-21
Abstract: 615,062. Electromagnetic switches. OLSSON, G. D. Aug. 21, 1946, No. 24950. Convention date, Aug. 30, 1945. [Class 38 (v)] In an electromagnetic relay a screwed shaft 6 is fixed to the core 4, and, when the core is axially displaced, causes the rotation of a member which at the end of its rotation actuates a moving contact member. In the form shown, the screw 6 passes through a fixed plate 8 so that axial movement of the core causes the rotation of the core itself and of an arm 22 which at the end of its stroke strikes a pin 19 on rotary contactcarrying disc 17 causing contacts 20 to engage contacts 13, 14 and a spring 9 to be wound up. The above movement of the core as well as the return movement under the action of the spring 9 when the e-magnet 2 is de-energized, is retarded by a centrifugally-urged member 24 on the end of a spring 23, which rubs on the inside of a drum 25. Near the ends of the stroke the member 24 reaches a gap in the drum so that retardation ceases and a quick action ensues. In a modification, the core 4 does not rotate and its axial movement rotates a member in screw-threaded engagement with the screw 6. In a modified retarding device, the rotary core or member is connected by a spiral spring to a heavy rotary disc, Fig. 5 (not shown).

Abstract: 225,015. Hermann, C., and Horne, R. W. Oct. 10, 1923. Printing. - surfaces; etching.-An intaglio printing - surface, made from a plate or surface of metal or stone grained in the ordinary way and prepared by positive printing or transfer, is etched so that the depth of the etched areas a varies in accordance with the tone values, and the pits are surfaced with shellac or a similar resin which is insoluble in the fatty menstruum of the printing-ink or in acids and which adheres to the material of the plate and to the ink. The plate, after graining, exposing, and developing, is rolled up with a resist which is of the nature of printing-ink with the addition of a solvent or menstruum of low melting-point, such as vaseline, so that, on the application of heat during etching, the resist will melt and gradually spread over the unprotected areas and progressively stop the etching action. The heat may be applied externally either locally or generally as desired, or may result from the reaction between the plate and the etching acid. If etching is performed with nitric acid, gum is added in order to keep the etched cavities in a condition to take moisture and repel fatty ink. After etching, the resist is removed and the plate inked with fatty ink, a solution of shellac or other resin being then poured over the plate. The shellac, ink, and photographic film are then removed from the unetched areas c and these parts are treated to render them fat-repelling.
