Title: Improvements in vacuum tube amplifiers
IPC: H04B3/08
Filed: 1931-01-29
Abstract: 371,887. Valve amplifying circuits. STANDARD TELEPHONES & CABLES, Ltd., Columbia House, Aldwych, London.- (Assignees of Black, H. S. ; 820, Oak Avenue, Westfield, New Jersey, U.S.A.) Jan. 29, 1931, No. 2894. Convention date, March 26, 1930. Addition to 317,005, [Class 40 (v), Wireless signalling &c.]. [Class 40 (v).] In a valve amplifier having a feed-back path for applying to the input a distortion compensating voltage as described in the parent Specification, control means are provided in the feed-back path to correct for distortion, i.e. phase shift, frequency attenuation, or gain variation, arising in other portions of the system. The invention is particularly applicable to multiplex carrier signalling and the distortion is corrected by introducing a similar distortion, instead of a complementary distortion as usually employed, in the feed-back path. The Figure shows an amplifier for a frequency range 4-40 KC in which both plate and grid supplies are decoupled and having the input taken from one arm 9 of a Wheatstone bridge, while the line is applied to diagonal 6, 7 and the feed-back path to diagonal 7, 8. The output also employs a Wheatstone bridge Ro, K, KR, KRo, with the line connected across one diagonal and the feed-back path across the other diagonal. As shown, the feedback path includes attenuation equalizing networks 21, 22, which may also give phase correction, gain control network 23, and a gainregulating transmission equalizer 24 which compensates for attenuation variations with frequency such as may be produced by temperature changes. The conjugate relation of the input and output to the feed-back circuit prevents the feed-back action from affecting the impedances with which the amplifier faces the lines and conversely prevents variation in line impedance from affecting the feed-back.

In a method of X-ray crystallography which permits the ready detection of stacking faultse.g. mosaic structure-in a crystal E, the beam from the linear focus F 1  of an X-ray tube is passed through the vertical and horizontal slots F 2  and F 3  to provide a planar diverging beam D of angle α incident upon the crystal, which is arranged, by rotations 1 and 2 about perpendicular axes, such that a given set of (hkl) planes is vertical and, at some point of the irradiated surface, satisfies the Bragg condition. The crystal is then rotated or oscillated at uniform speed through an angle limited to that which is necessary to ensure that all the planes of the set over the whole irradiated surface successively satisfy the Bragg condition, whereby missing or misdirected planes give rise to clear regions in the otherwise substantially uniformly blackened band recorded on the stationary photographic film P. In the apparatus of Fig. 2, a diverging beam from the horizontal slot F 2 -of 10 to 30 microns height-is incident on the specimen E, which is rotatable about a horizontal axis by a worm and pinion, and is mounted on a base 8 rotatable to and fro at constant speed about a vertical axis by mechanism 9, a counter in tube 11 permitting initial adjustment of the specimen to a suitable position with the pivotally mounted film 10 in a raised position. The film 10 may alternatively be mounted in front of the specimen, to receive reflected rays.

Abstract: 1,083,461. Means retaining sleeves on shafts. BRITISH IRON & STEEL RESEARCH ASSOCIATION. Jan. 25, 1965 [Jan. 23, 1964], No. 2952/64. Addition to 994,987. Heading F2U. Means retaining a sleeve 1 on a shouldered shaft 2, particularly a roll sleeve on a cantilever mill shaft, comprises a nut 6 in screw-threaded engagement with a locking ring 26 having internal radial bayonet lugs 27 co-operating with external bayonet lugs 4 on the end of a reduced part 3 of the shaft. In operation, the engaged nut and locking ring are passed over the end of the shaft part 3, the lugs 27 passing between the lugs 4, and the nut is then rotated in one direction to effect, in sequence: (i) rotation of the ring until the lugs 27 are aligned with external bayonet lugs 4 on the shaft part 3, such ring rotation being limited by engagement of long axial limbs extending from the lugs 27 with one set of radial edges of the lugs 4; (ii) leftward screwing of the nut along the ring until the nut engages the sleeve 1; (iii) rightward axial movement of the ring, the nut meeting resistance to forward movement, until the lugs 27 engage backs 5 of the lugs 4, short axial limbs extending from the lugs 27 then engaging with the opposite set on radial edges of the lugs 4 so that the ring is held from rotation in either direction relative to the shaft; and (iv) screwing up of the nut tightly against the sleeve. As shown, the nut is circumferentially looked to the shaft by a plunger 14 radially slidable in the shaft. When the nut is tightened up and a spring-loaded retaining pin 21 withdrawn, the plunger is urged, by a spring 17, into engagement with one of slots 12 in a plate 11 secured to the nut. When the shaft rotates, the spring 17 is assisted by centrifugal force. The nut acts on the sleeve 1 through a thrust ring 7 and a dished washer 9 which prevents j jamming of the screw by differential thermal expansion between the sleeve and the shaft and facilitates the entry of the plunger 14 into a slot 12. In Figs. 5-10 (not shown), the dished washer 9 is dispensed with, the spring-urged plunger and slot circumferential locking means is provided between the nut and the locking ring, and the nut is provided with C-spanner projections.
