Title: New or improved means for effecting axial location of a rotating shaft
Inventor: TUPLIN WILLIAM ALFRED
IPC: F16C35/06
Filed: 1950-05-13
Abstract: 683,835. Machine-tool details. BROWN & SONS (HUDDERSFIELD), Ltd., D. May 15, 1951 [May 13, 1950], No. 11981/50. Class 83 (iii). [Also in Group XXIV] In a device for precisely locating a shaft, such as an indexing worm-shaft of a gear-cutting machine, in different axial positions according to its direction of rotation, the shaft s carries a collar s<SP>1</SP>, lying between two thrust surfaces m, n, and a brake drum a. The drum a is engaged by brake shoes b on a plate c which is non- rotatably coupled to the shaft through thrust bearing d. The plate c carries a member c<SP>1</SP> and a screw which co-operates with a nut g fast against rotation but axially movable against a spring h. Pins e, el on member c<SP>1</SP> limit the rotation of plate c with respect to a pin f on nut g. Thus, in accordance with the direction of rotation of shaft s, a frictional drag is applied to plate c and the serew j screws into or out of the nut g to move it axially to apply an axial spring-load on the shaft to move it against either thrust surface n or m.

Title: Improvements in or relating to electric multiplication circuits
IPC: G06G7/163
Filed: 1956-04-19
Abstract: 827,658. Parametrically excited resonators. GOTO, E. April 19, 1956 [April 25, 1955], No. 11991/56. Class 40 (9). [Also in Groups XIX and XXXVI] An electric analog multiplication circuit receives input signals Sx, Sy, Sz in a first linear circuit applying composite signals u1 = Sx+Sy+Sz u2 = Sx - Sy - Sz (1) u3 = Sx+Sy - Sz u4 = -Sx-Sy+Sz to corresponding distinct non-linear channels each having a characteristic Ui = a1ui + a3ui<SP>3> where Ui and ui are the input and output signals and a1, a3 are constants, which channels supply corresponding output signals U1, U2, U3, U4 to a second linear circuit from which is derived an output signal Sw = U1+U2+U3+ U4 analogous to the product [Sx, Sy, Sz]. In an application to a binary full adder circuit of a digital computer, parametrically excited resonators P1, P2, P3 receive respective phasecontrolling signals Sx, Sy, Sz and yield three respective oscillatory currents, representing binary digits according to the phase or polarity difference therebetween to terminals tx, ty, tz. The latter respectively energize corresponding primary windings (connected in series in appropriate senses) of four transformers wound on saturable ferrite cores B1, B2, B3, B4 which each have a single secondary winding series connected to develop at the combined output a signal representing in binary code the sum digit of the three input binary coded digits. Specification 778,883 is referred to.

Buildings and chambers; air and gases, controlling circulation of.- In a method of drying bricks &c. prior to firing, the drying-apparatus is first supplied with air heated by radiation from the oven, and then with air used for cooling the fired products, and, lastly, with hot gases from the oven. A number of drying chambers c are arranged above the oven 2 and communicate on each side through doors 11 with channels 10 which extend along the whole length of the, apparatus. The chambers are divided into a number of groups, for example six, and a different operation is performed in each group, with a daily change of operation in each group. In the first group the doors 11 are open, and trucks carrying the articles are discharged and charged through double doors in the outer casing. In the second group the doors 11 remain open and moist air stored in the channels 10 during another stage is drawn by a fan through the chambers and through openings 14 to an outlet duct 7. In the third group the doors 11 are closed, and casings 12 containing a fan 13, Fig. 6, and provided with dampers 18, 20, 23 are arranged at the bottom of the doors. The dampers are set as shown in Fig. 6 and moist air is circulated by the fans 13 through the chambers, pipes 16 and openings 14 in a closed circuit. This stage may be omitted for coarse products. In the fourth group, air heated by radiation from the oven is drawn into the chambers and circulated by the fans 13, the dampers 18, 20, 23 being so arranged that the whole or part of the air passes into and through the channels 11 where part of the moist air is stored. The fifth group has a similar air circulation, but hotter air used for cooling the fired products is supplied by a duct 4 with or without additional hot air from a duct 6. In the last stage the casings 12 are removed, the doors 11 remain closed, and burnt gases from the kiln are drawn through the chambers from the duct 5 to outlet ducts 8.

Abstract: 1,138,934. Ammonium salt of pyrrolidone carboxylic acid; aminolactams. STAMICARBON N.V. 16 March, 1967 [16 March, 1966], No. 12451/67. Heading C2C. The ammonium salt of 2-pyrrolidone-5-carboxylic acid and an aminolactam are obtained by splitting a 2-pyrrolidone-5-carboxylic acid salt of an aminolactam by treatment with a stoichiometric excess of ammonia in a substantially anhydrous organic liquid medium in which the ammonium salt of 2-pyrrolidone-5-carboxylic acid is substantially insoluble and in which the aminolactam is soluble, and separating the ammonium salt from the liquid phase. Ethanol, n-propanol, n-butanol and mixtures of methanol or ethanol with toluene or benzene provide suitable liquid media. The process may be used to split salts of an optically active pyrrolidone carboxylic acid and an optically active lactam in the resolution of racemic mixtures of D- and L-amino lactams. An example describes the preparation of the ammonium salt of L - 2 - pyrrolidone - 5 - carboxylic acid and L - α - amino - # - caprolactam from the salt of L - 2 - pyrrolidone - 5 - carboxylic acid and L-α-amino-#-caprolactam.
