IPC: F24F3/14
Filed: 1929-01-03
Abstract: 331,523. Hall, J. H., Kay, P., and Hall & Kay, Ltd. Jan. 3, 1929. Ventilation apparatus comprises valve means whereby fresh air drawn from the outside atmosphere, or air drawn from the enclosure, to be ventilated, or a mixture of fresh air and withdrawn air may be passed through a temperature regulator, and then to the enclosure, either directly, or after further treatment, such as humidifying, of the whole or part of such air. The fresh air duct 4, and withdrawn air duct 9 are controlled by dampers 8, 10 and communicate with the temperature-regulating chamber 5. The latter chamber opens into a vertical duct 12, the lower end of which is controlled by a damper 13 and opens into the conditioning chamber 6 and the upper end of which opens to a bye-pass duct 14 controlled by a damper 15. The duct 17, which delivers to the enclosure, is connected to the duct 14 and also to a duct 18, controlled by a damper 19, leading from the chamber 6. The dampers 8, 10, 13, 15, 19 may be interconnected for simultaneous operation by a common chain 34 passing over sprocket wheels on the shafts of the dampers as shown in Fig. 2, the arrangement being such that the dampers 10, 13, 19 are closed or partly closed concurrently with the dampers 8, 15 being opened or partly opened, and vice versa. The damper operating gear may be actuated by a hydraulic motor 35 controlled by a hydrostat in the enclosure. In the case where the whole of the air is drawn in from the outside and passed direct to the enclosure after passage through the chamber 5, the, amount of fresh air admitted may be regulated by a secondary damper 8<a> operated independently under thermostatic control. The size of the damper 8<a> may be such as not to close completely the fresh air inlet 7. The chamber 5 is provided with a steam-heated radiator 11, and the chamber 6 is provided with a set of hot water sprayers 20<a> and cold water sprayers 22a.

Title: Remote control system for arc electro-welding apparatus
IPC: B23K9/10
Filed: 1949-01-12
Abstract: 661,567. Control systems for welding arcs. NAESS, A. ALMAR-, and ROLFSJORD, N. O. Jan. 12, 1949 [Jan. 12, 1948], No. 850/49. Class 38 (iv). In an arc welding system in which the welder can remotely control the voltage of the source of welding current 1. by varying the impedance of the welding circuit (when his electrode 4 is clear of the work) by bringing into contact with the work one or the other of two auxiliary electrodes 5, 6, preferably carried by the main electrode holder and connected to the welding cable through resistors Ra, Rb of different values, the voltage adjustment is effected by a servomotor through relays A, B energized from an auxiliary circuit E, F inductively coupled to the welding circuit. The arrangement is such, that when the welder brings one resistor into the welding circuit the current circulating in the auxiliary circuit is such as to cause only one of the relays to respond and bring about voltage adjustment of the source in one direction. Bringirig the other resistor into circuit causes an increase of current in the auxiliary circuit, with the consequence that both relays respond and cause voltage adjustment in the opposite direction. A relay D, d1, responsive to the main electrode voltage (or the voltage across the points E, F) normally maintains the auxiliary circuit open. The servomotor circuit is normally maintained open by normally open contacts of a delayed relay T which is energized in series with the relays A, B. When the welding current is D.C., the inductively coupling of the auxiliary circuit, which must now be provided with a separate source of A.C. energization, to the welding circuit is by a transductor, the A.C. winding of which is connected in series with the relays A, B, T, whilst the D.C. winding is in the welding circuit. The auxiliary circuit may control the relays A, B, T through a valve amplifier.
