Filed: 1927-10-14
Abstract: 279,438. British Thomson-Houston Co., Ltd., (Assignees of Carpenter, C. F.). Oct. 21, 1926, [Convention date]. Controllers, multiple rocking-bar; control systems for alternating-current motors.-Electric motor-starting switches for making two sets of connections one after the other, as in the starting of alternating-current motors by means of an auto-transformer giving reduced voltage followed by full voltage, are constructed with two groups of movable contact-members 12, 15 and two transmission shafts 20, 21, each shaft being coupled through vertical rods 24 and crank-arms 26 to one group of contacts. An operating handle 17 has a linkage connection to a bell-crank lever 37 working on an offset shaft 40, and thence through members 22, 38 to the respective shafts 20. 21. The shape of the bell-crank lever and the disposition of the coupling members are such that the first or starting movement of the handle from the position of Fig. 4 to that of Fig. 5 rocks the shaft 20 while leaving the shaft 21 practically unaffected. This closes the first group of contacts 12. Further movement of the handle 17 in the same direction rocks the shaft 21 while leaving the other unaffected, both groups of contacts being thus finally closed. In the construction shown a third group of movable contacts 27 is actuated through an additional linkage 30 from the shaft 21 so as to open a neutral-point connection in the auto-transformer windings when the handle is moved to its final position. Automatic releasing means of known kind may be provided. The switches are oil-immersed and are mounted in a framework along with a suitally tapped auto-transformer. The circuit connections of the motor 10, the auto-transformer 14. and the switch-groups 12, 15. 27 are shown diagrammatically in Fig. 3. Specification 232,922 is referred to.

Abstract: 1,009,037. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. July 19, 1962, No. 27782/62. Heading H4K. Analogue signals are sent over one-way channels between two exchanges representative of the conditions existing at the terminal circuits. The principle is shown in Fig. 5 in which signal adaptors are connected by one-way circuits CSG, CSR. At each end pulses from a source PPS are modulated in width or otherwise according to the potential at LI, LO and are transmitted to an RC network at the other end, and also in inverted form to the RC network at the same end. At the near end, a comparison is made and one or other of two transistors T3, T4 conducts, current being supplied to or drawn from LI. A similar comparison is made at the far end, and in due course the potentials at LI, LO are brought into agreement. As applied to inter-exchange working, Fig. 6, the arrangement is duplicated, and the signal transmission is controlled by the potentials at LI, LO at both ends. The closure of the loop at the near end results in the operation of relay A, which subsequently responds to dialled impulses.

Abstract: 676,676. Roller - and - ring briquetting- machines. HUBMANN, O. Nov. 14, 1950 [Dec. 19, 1949], No. 27842/50. Class 87(ii) Two revolving rings 1 directly support each other and encompass two eccentric rollers 2. The rollers 2 are fixedly mounted, and the rings " float " between them. The rollers may be mounted on elastic bearings. One or both rings is supported from below by an auxiliary roller 6, and by adjusting this roller the gap between the roller and ring may be varied. The roller may be resiliently mounted, e.g. on springs or on a hydraulic piston 13. The hydraulic piston may exert different working pressures on the material. By keeping the pressure constant and varying the feed the thickness of the briquettes may be altered. One roller only may be positively driven, the drive to its ring and to the other roller and ring being by friction. The moulding groove may be in the ring or, as shown at 7, in the roller, and its base may be entirely or partly formed. by a loose ring 16 which has a larger diameter than the said base, and this loose ring forces the briquettes out of the groove. There may be a double moulding groove as described in Specification 474,780. At 17 a recess may be formed in the roller to retain the briquettes and thus facilitate its removal; the same effect is obtained if the groove is made deeper at 17 than on the side containing the loose ring 16. The material is fed to the groove through shoots 11 and is prevented from falling into the no-pressure space by a spur 9 which ejects the briquettes into a funnel 15.
