[Also in Group XIX] A viscosimeter has a shaft 14 supporting a vane 5 for immersion in the liquid to be tested, a sleeve 10 surrounding the shaft 14 and arranged to be rotated at constant speed, and spring means 20 interconnecting the shaft 14 and sleeve 15 to allow relative rotational displacement between the two, the shaft 14 and the sleeve 10 each having secured thereto and rotatable therewith a member such that on relative rotational displacement between the shaft 14 and the sleeve 10 the members co-operate to cause an indicated change in an electrical circuit, of which circuit part is formed by one or both of said members. The co-operable members may comprise a circular potentiometer in a cup 15 secured to the sleeve 10, whose slider is secured to the shaft 14. In a further embodiment, Fig. 2, the co-operable members comprise a double-wound, air-cored transformer 29 secured to the sleeve 10 and a tapered plunger 25 of ferromagnetic material secured to the shaft 14, the arrangement being such that relative rotational displacement between the shaft and the sleeve results in the plunger 25 being moved into the transformer core 29, so changing the coupling between the transformer windings.

Title: Improvements in method of brazing tubing
IPC: B23K1/00
Filed: 1924-02-25
Abstract: 220,246. Snead & Co., (Assignees of Macdonald, A. S.). Aug. 21, 1923, [Convention date]. Brazing.-Brass or other metal tubes with overlapping or butted longitudinal seams are brazed by applying spelter, preferably in pasty form, to the joint, supporting the tube against distortion while leaving it free to expand during heating, and heating by the electric resistance process to melt the spelter. The tube is preferably arranged in an horizontal plane with the seam uppermost, and is supported by pairs of jaws, one jaw of each pair being movable and pressed forward by a weight &c. The heating effect of the cement which passes from one jaw through the tube to the other jaw is controlled, preferably by the expansion of the tube. For this purpose the movvable jaw is associated with a pointer and contact, so that when the tube has expanded an amount indicative of the proper temperature the circuit is broken. On cooling again the circuit is automatically reestablished, and so the temperature is maintained substantially constant for a few seconds. When the spelter is melted the current is cut off. In a modification, the pointer may be arranged to reduce the current when the proper temperature is reached, and so maintain the tube at the desired temperature.
