Abstract: 191,206. Faþoneisen - Walzwerk L. Mannstaedt et Cie, Akt.-Ges., and Bansen, H. Oct. 22, 1921. Regenerators; gaseous-fuel furnaces.- In a hot-blast stove a combustion chamber d is arranged beneath vertical heating passages g, which are formed, as shown in Fig. 1, of brickwork built up of individual arched layers each separately supported by the outer wall a, which may thus be made of diminishing strength towards the top. Empty arched chambers, Fig. 17, may be arranged between the layers, and an insulating layer v is provided between the wall a and the refractory lining f of the combustion chamber. The arches may be built up of bricks of various shapes, two of which are shown in Figs. 12 and 14, these shapes being such that, when the arch is completed, the passages g are all of the same cross-sectional area. This construction of heating passages may also be applied to furnace regenerators. In the case of a hot-blast stove, gas pipes n deliver tangentially into the combustion chamber and are arranged concentrically within air pipes m which communicate with the atmosphere through openings closed by dampers o. In operation, the dampers o are opened and the brickwork heated to the required temperature, the waste gases escaping through the pipe k. The gas-supply valve q and the cover l are then closed and air allowed to flow in through the pipe s and pass down through the heating passages g to the pipes m, being finally drawn off through the conduit u.

Title: Improvements relating to mechanical displacement-magnifying systems
Inventor: WIGAN EDMUND RAMSEY
IPC: G01D5/04
Filed: 1948-11-04
Abstract: 674,856. Dial gauges; indicating-apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Nov. 1, 1949 [Nov. 4, 1948], No. 28718/48. Classes 106 (ii) and 106 (iv). [Also in Group XXXII] A device for the magnification of small displacements comprises a spring arrangement of positive stiffness in combination with a spring of negative stiffness, the springs being in series and their relative stiffnesses being such that a displacement or input deflection between the ends of the spring arrangement of positive stiffness results in a magnified deflection at the junction of the spring arrangement of positive stiffness with the spring of negative stiffness. As shown in Fig. 1 (Prov.), the spring arrangement of positive stiffness is two springs S1 and S2 in series, S3 being a spring of negative stiffness. Deflections of the point A along EE cause magnified deflections at the point B. Alternatively the springs S1 and S2 may be a continuous coiled spring, the input deflections being applied to a tapping-point by a plug meshing with the coils of the spring. In Fig. 1 (Comp.), the positive spring arrangement is a single cantilever blade 1 gripped at one end 4a, input deflections being applied to a stud 9 along its length by a pin 8. A negative " sinespring " 2 is coupled at or near the free end of the cantilever 1 by a flexible blade 3. Movement of the stud 9 is magnified by the free end of the blade 1. The blade 1 may be of increased cross-section between the stud 9 and the gripping means 4a. The zero position of the blade 1 is adjusted by a screw 5 acting on the means 4 and hence the blade 1. The magnification factor of the instrument can be adjusted by altering the angles at which the ends 2a, 2b of the " sine-spring " 2 are fixed. Specification 617,076, [Group XXXII], is referred to.
