Title: Scale weight totalizing device
Inventor: SCHELLENTRAGER EUGENE WILLIAM
IPC: G01G23/18
Filed: 1952-05-14
Abstract: 704,649. Weighing apparatus. ATLAS BOLT & SCREW CO. May 14, 1952, No. 12223/52. Class 143 [Also in Groups XIX, XXIV and XXXVIII] A weighing and recording arrangement for a number of different materials (e.g. coke and limestone) that are loaded in succession into a truck that carries the composite load to the skip hoist of a blast furnace, is provided with a dial to indicate, and a printed tape to record, the loads carried on each journey, and with counters which selectively totalize the weights of the individual and of the composite loads carried over a period of time. 'The truck has two hoppers resting on weighing levers driving a shaft 24, Fig. 2, which operates a pointer 26 and a type wheel 28 which moves beneath a hammer 29 and paper tape so that its load is printed when a solenoid 33 is manually energized. A second type disc 40 is rotated either manually or automatically to a position dependent upon the particular material being loaded so that an identifying code is printed with the load. The automatic setting is achieved by a selsyn 49 which is coupled by trolley wires to the appropriate selsyn 43a ... d, Fig. 9, located at each' of the charging bins and pre-set to individual identifying positions. Selsyn 49 also operates a selector switch 41 through which the magnet coils of a number of magnetic clutches, e.g. 59a are energized. Each clutch can connect a totalizing counter, e.g. 53a to a selsyn 64 coupled to a selsyn 65 driven by the weighing mechanism. Hence on receiving a particular load, the appropriate totalizer is connected and the load is added to the existing total. A similar counter, but geared oppositely to the previous, is driven by the movement of the weighing mechanism as it returns to zero when a complete load is dumped.

[Class 83 (iv)] In a method of automatic arc welding using a succession of self-starting touch-welding rods, in which the rods are arranged above a seam so as to deposit metal therein and all but the first of the rods are insulated from the work at their tips and in which, after ignition of the first rod, the arc progresses along the seam until adjacent the tip of the next rod, the arc length of the first rod is then increased so that its arc is extinguished, the insulation between the next rod and the work is broken. down and an arc is struck between this next rod and the work. The coating of the rods may consist of 12 per cent of calcium fluoride, 13 per cent of calcium carbonate, 7 per cent of ferro-alloy, 61 per cent of powdered iron and 7 per cent of water glass and aluminium silicate. Two guide rods 3 angularly adjustable and also laterally adjustable along and secured by screws in a slot in a transverse bar 7 mounted on posts 1, serve as guides for members 12, 13 to which the coated welding rods 10, 11 are secured. The arc is started at the electrode 10 and when this is substantially consumed the member engages a stop 14 and the arc lengthens and the arc voltage increases sufficiently to cause the insulating paper 15 on the end of the rod 11 to burn and the arc to be formed at the end thereof to continue the welding operation. The insulating layer of paper initially on the end of the rod normally bears on the work to prevent premature ignition. Specifications 550,727 and 623,383 are referred to.
