IPC: G01L3/14
Filed: 1945-05-25
Abstract: 593,238. Dynamometers. BRITISH THOMSON-HOUSTON CO., Ltd. May 25, 1945, No. 13088. Convention date, May 27, 1944. [Class 106 (ii)] A device for measuring the torque in two coaxial shafts cumulatively or separately, transmits the power to a driven load by means of a third shaft arranged substantially at right angles to the first two shafts. In the case of two concentric shafts, the outer shaft 1, Fig. 1, is mounted by means of antifriction bearings in an, outer housing 3 and power is' transmitted from the outer shaft to a third shaft 5, also mounted in the outer housing, by means of bevel wheels 7, 8. The inner shaft 2 is mounted by means of antifriction bearings in an inner housing 11, which is rotatably mounted in the outer housing, and transmits power to a shaft 14, mounted in the inner housing, by means of bevel wheels 16, 17. The shaft 14 is connected to the third shaft 5, through a slot in the inner housing, by means of two universal joints and a sliding splined coupling 19 and the third shaft 5 is similarly connected through a coupling 23 to a controllable variable load on a shaft 26. The outer housing is rotatably mounted in a frame 27 and this housing and the inner housing tend to rotate in opposite directions due to the power transmissions from the outer shaft 1 to the third shaft 5, and from the inner shaft 2 to the shaft 14 respectively. An articulated connection is secured to the outer housing at one end and, by means of a ball-and-socket joint, to a link 32, Figs. 1 and 2, at the other end. The link 32 is similarly connected to the inner housing through a slot in the outer housing and is pivotally mounted between these connections on a boss 33. The force exerted by the link 32 is transmitted by means of a bell-crank lever 39 and a system of links to a spring balance 45 and a balance mechanism 46. In order to avoid stresses arising in the third shaft 5 due to large angular movements of the outer housing, the frame 27 and balance mechanism are mounted on a turntable 50, Fig. 4, and a contactor 55, secured to the link 32 as shown in Fig. 1, is arranged between two stationary contacts 56, 57. On rotation of the outer housing, one of the contacts is closed and an electric motor 52 operates through a worm 53 to rotate the .turntable in such a direction that the third shaft 5 is again brought into line with the load shaft 26.

Abstract: 847,526. Multiplex telegraphy. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 22, 1958 [April 25, 1957], No. 13182/57. Class 40(3). Five-unit telegraph code combinations in a fifteen channel time-division multiplex system in which the five elements forming the combinations are transmitted simultaneously over five paths 1-5 are distributed by a first set of five commutators E-K channel-by-channel to a second set of fifteen commutators K-Z, the inter-connections between the sets of commutators being such that the elements are distributed circumferentially around the commutators K-Z so that they may be regenerated sequentially in the standard form required for teleprinter operation. Thus considering channel 1, the five elements appear simultaneously at the input brushes 7-11 at the first commutator segments El, Fl- - - K1 and are connected to segments L1E1, L2F1, L3G1, L4H1, L5K1, spaced around commutator L, capacitors C1-C5 being provided to store the elements so that they may be regenerated in sequence at brush 12 for application through a valve V1 to the teleprinter for the first channel. A capacitor C20 holds the potential at the grid of V1 during the interval between contacting segments L1E1, L2F1, &c. Segments 37 and 38 are maintained at fixed potentials and serve to introduce start and stop signals, the spacing between the segments being such that the stop interval lasts for 1 ¢ elements. In a similar manner for channels 2, 3, 4 &c. to 15 the elements are distributed to commutators M, N, O &c. to Z, the corresponding segments utilized in successive commutators being displaced angularly as shown in accordance with the time spacing of successive channels. Brushes 27, 28 - - 31 preceding brushes 7, 8- - 11 on commutators E-K serve to discharge the capacitors associated with commutators L-Z before the application of a subsequent code combination. The apparatus may be used in a reverse manner to assemble teleprinter signals in time multiplex with the sequential elements of each code combination converted into simultaneous form. Slip rings, A, B, and C, connect with power supplies. A commutator D serves to generate a square wave signal at brush 6 for synchronizing purposes. Commutators D-Z together with slip rings A-C are assembled on a common shaft in the form of hollow cylinder within which are housed the capacitors associated with commutators L-Z.
