Title: Method and device for recording the work of arc welders and in general, of workmen utilising an electrode welding circuit
IPC: G07C1/08
Filed: 1933-10-23
Abstract: 419,235. Recording - apparatus. SARAZIN, R., 48, Boulevard d'Asnieres, Neuilly-sur-Seine, France. Oct. 23, 1933, No. 29367. Convention date, Oct. 22, 1932. [Class 106 (iv).] The time actually spent by a workman in electric welding is recorded and counted up automatically. The welding period is represented by the time during which the voltage is between 15 and 35, such range operating relays 5 and 6 to energize the coil 7, the pole 11 of which is drawn down towards the soft iron drum 12 against the pull of the spring 15. On the pole 11 is mounted a driving wheel 16 of a counter 18 and a stylus 14 which marks the working period on a sheet of paper 13 on a drum 12 rotated at a uniform speed. The dashes marked on the paper represent the times of welding while the wheel 16 contacts with the paper 13 during welding and registers the total time on the counter 18. To register and record the next day's welding, the apparatus is moved axially along the drum, the coil and recording means sliding down the spindle 10, and the knob 21 being shifted to the next slot in the guide plate 22. An opening 23 allows the workman to write personal remarks on the record sheet. In recording for a number of workmen, each workman's welding circuit is coupled, e.g. by jack plugs to a separate recorder, but all recording is shown on one strip of paper pulled past a stylus at a required speed. The stylus in this case depresses the paper against a carbon sheet to mark on the other side of the strip.

Abstract: 210,546. Keay, R. W. Nov. 8, 1922. Moulding-machines. - The drawing movement in a moulding-machine is effected directly or indirectly by air and controlled by oil or other liquid flowing through a manually-regulated valve. Drawing-cylinders have pistons which are connected to hand-operating gear 6, 7, 8, thus ensuring synchronous movement, and, when desired, to the turn-over table 3 by devices 9. Pipes 33, 34 connect the bottoms of the cylinders 4 and of a reservoir 19 through a plug valve 17. The upper end of the reservoir can be connected by a pipe and ports 26, 28, Fig. 4, in the same valve, or in another valve operatively connected therewith, to a supply of compressed air 12 or with exhaust 30. The port 26 has extensions 27 which admit compressed air before opening the oil-control port 23 and another port 28 may be arranged to admit compressed air through a flexible pipe 36 to a vibrator 20 at the same time. This port, however, is closed when the oil-control port is fully open. The oil in the cylinder 4 may be freed from air by means of a slit screw 38, Fig. 7, in the piston. Before drawing, the mould may be jarred by a cylinder 2 supplied with air through a valve 16 and exhausted through 15. In a modification, the drawing-piston is operated by compressed air admitted below it and is controlled by throttling the escape of oil from above the piston, this oil being admitted during the return movement. In another modification, separate valves are used to control oil and air and are mechanically connected so that they can be operated correctly by a single handle. Pattern-drawing cylinders operated as previously described may also be applied to existing handoperated machines.
