Title: New or improved toy or doll device
IPC: A63H3/28
Filed: 1928-03-22
Abstract: 304,512. Christensen, E. G. K. March 22, 1928. Dolls. - A doll comprises a head provided with a deformable mouth formed by an opening in a sheet of rubber or the like and connected to movable eyes through flexible connections, and a control device located in the body of the doll, the control device being manually operable to impart movement simultaneously to the mouth and eyes. The eyes are arranged on a band 6 the ends of which are connected respectively to an elastic strip 7 that is secured to the face part, and to a tape 8 which passes through a hole 9 near the ear and is then carried down through the head and chest to the underside of a flap or lever 5. The doll is composed of the parts 1, 2 of moulded paper pulp, and the eyes on the band 6 are located opposite to eye openings in a rubber mask 15 that is moulded with human facial features, the parts 15, 1 being stuck together by a suitable cement. A mouthpiece 12 with a shaped mouth opening is secured to the back of the mask, and to the ends of the plate are attached tapes 10, 11 connected to the flap or lever 5. The plate 12 may be of rubber or extensible material so that it will stretch, or one of the tapes 10 or 11 may be elastic. When the doll figure is pressed, as between the fingers, the flap 5 will be depressed to cause a pull to be exerted on the tapes 8, 10, and 11. This causes the eves to be moved towards one side of the eye slits and the mouth formation of the mask to undergo a change. The pressure upon the doll figure produces also a collapse of the bellows 17 and a sound to be emitted.

Title: Devices allowing the measurement and adjustment of the resistance of an electrolysis cell
IPC: C25C3/20
Filed: 1945-04-09
Abstract: 591,016. Resistance measurements. COMPAGNIE DE PRODUITS CHIMIQUES ET ELECTROMETALLURGIQUES ALAIS, FROGES, ET CAMARGUE. April 9, 1945, No. 8762. Convention date, April 7, 1944. [Class 37] The resistance of an electrolytic cell is measured by measuring the ratio between a voltage proportional to the current through the cell and a voltage proportional to the voltage at the terminals of the cell reduced by a voltage equal to the E.M.F. of the cell. Alternatively, one voltage may be proportional to the voltage at the terminals of the cell and the other to the current through the cell increased by a constant term. As shown in Fig. 1, one coil 1 of a crossed-coil instrument is supplied with a voltage proportional to the current through an electrolytic cell 10, either by means of a shunt 2 or by a D.C. transformer. The other coil 3 has a voltage applied to it which is the difference between the voltage at the terminals of the cell 10 and a voltage equal to the E.M.F. of the cell which is tapped off from a potentiometer 5 supplied by a battery 4. The instrument may close relay contacts 8, 9 and thereby indicate whether the resistance is above or below the normal value. In a modification, Fig. 2, in which a number of electrolytic cells are connected in series, a voltmeter 11 is connected across each cell 10. A second circuit including a potentiometer 13 corresponding to each cell is' supplied by a D.C. current transformer 14. A voltmeter 12 is connected across the tapped-off portion of each potentiometer 13 and is graduated so that its zero reading corresponds to the E.M.F. of the corresponding cell. Each potentiometer 13 is adjusted so that when the current is at its normal value the voltmeter 12 indicates the desired voltage across the corresponding cell. The electrodes of the cells are then adjusted until the corresponding voltmeters 11, 12 are in agreement. In another modification, Fig. 4, a differential moving coil instrument is connected to each cell 10. One coil 15 of each instrument is connected across the corresponding cell, the other coil 20 being supplied from a potentiometer 17. These potentiometers are in a circuit supplied by a shunt multiplier 16 in series with a potentiometer 18 fed from a constant voltage source 19, so that the current through the potentiometers 17 is proportional to the current through the cells 10 increased by a constant current from the potentiometer 18. Contacts 21 or 22 are operated according as the resistance of the cell is above or below normal and may operate a signal or control automatic regulation.
