Title: Improvements in or relating to refractory compositions
IPC: C04B28/26
Filed: 1945-06-22
Abstract: A refractory substance for use in repairing or lining furnaces or casting moulds comprises a solid granular or powdered material which, on heating, yields water to effect self-tempering and setting of the composition.  The material is preferably an alkaline silicate containing water of crystallization, e.g., sodium metasilicate which contains up to nine molecules of water. The material is powdered and mixed with any refractory material, e.g., silica, alumina, clay, lime, chamotte, china clay, terracotta, quartz, magnesia, graphite, carborundum, zircon, or chromite, and the mixture is applied to the hot surface of the furnace or mould without previous tempering with water, whereby the water of crystallization is released and, after permeating the mass, is dried off leaving a hard refractory mass. When used as a lining for ingot moulds, the walls of the latter may be formed with depressions to keep the lining in place and metal reinforcements may be provided.

Title: Improvements in and relating to electric counting arrangements
IPC: H03K21/00
Filed: 1963-04-24
Abstract: 1,005,054. Counters. CONTRAVES A.G. April 24, 1963 [May 4, 1962], No. 16138/63. Headings G4A and G4D. Cycles from a multi-phase signal generator are counted in the positive or negative sense by a chain of binary counting stages, each stage of which repeats the pattern of the input signals on a like number of output lines with the cycle length multiplied by a whole number. The apparatus may be electrical, electronic optical, hydraulic or pneumatic. Rotations of a shaft, Fig. 1, produce square pulses with a phase difference of 90 degrees as seen at Da 0 , Db 0  in Fig. 2. The pattern produced on relays A 0 , B 0  is therefore OO-OLLL-LO for forwatd operation and OO-LOLL-OL for reverse operation. Relays A 0 , B 0  control relays A 1 , B 1  to produce the longer pulses in the third and fourth lines of Fig. 2, these pulses having the same pattern as the input pulses. Several stages may be connected together to form a cascade counter. Fig. 4 shows an electronic equivalent with input lines A 1 , A 1 , B 1 , B 1  feeding a network of AND gates U and OR gates to control two transistor pairs, the lower half of the Figure being schematic only. The stage may be reset by an impulse on lead R. Fig. 5 shows a four-stage decimal counter with an auxiliary stage HST so arranged that successive stages are weighted 1, 2, 2, 4. It has the advantage that reversal of all stages changes the count to its nines-complement. The electronic equivalent is described with reference to Fig. 6 (not shown). In Fig. 7, not shown, the outputs of two impulse generators 1G 1 , IG 2  may be added or differenced and in Fig. 8, not shown, the result may be accumulated on a multi-denominational counter of the type shown in Fig. 5. The input and output patterns may be threephase (Fig. 3, not shown). The systems described are insensitive to spurious pulses.

Filed: 1938-06-10
Abstract: 515,716. Elastic-fluid turbines. KOHLER, G., and BRAGARD, T. June 10, 1938, No. 17292. [Class 110 (iii)] A reaction rotor blade for radial-flow gas or steam turbines is so shaped that the angle a, Fig, 2, between the lines R, yy of radial centrifugal force and minimum moment of inertia respectively decreases with increase in bending moment. With blades held at one end Fig. 6, this decrease is towards the hub, while with the blades held at both ends, Fig. 7, this decrease is towards the centre of the blade. In Fig. 1, the sections 4... 1 correspond to the lines A ... D of Figs. 6 and 7. This decrease may be effected by increasing the inlet angle of the blade, or by increasing the ratio of the inlet and outlimb lengths, reckoned from the centre of sharpest concave curvature, as by a tangential extension. The under profile of the blade may be moved out, keeping the rear profile constant, and the blade thickness may be increased. The profile form generating the under and rear faces may move in a curved path such as a circular arc.
