Reel and web apparatus.--An indicator for street cars is arranged so that at each operation of a switch a band mounted on two rollers is moved so as to bring the next indication into view and then automatically stopped. An intermediate roller 14, driven by the friction of the band 5, and located between the band rollers 3, 4, forms a make-and-break switch in the circuit of an electric driving motor 30. The roller 14 has metal ends 15, 16 electrically connected together and has spring contacts 24, 25, 29 bearing thereon, the contacts 24, 29 being at opposite ends of the roller and continuously in electrical connexion therewith, while the contact 25 comes over, and engages a depression 27 in, a small vulcanite portion 28 set into the metal end 15 of the roller at every revolution thereof. The motor circuit is via leads 36, 40 to the motor, and from the motor via lead 48 to a switch 43 and thence alternatively by a lead 47 to the contact 25 or bv a lead 46 to the contact 24. When the band is at rest. the contact 25 engages the depression 27 in the insulating portion 28. To start the band the switch arm 42 is moved momentarily into touch with the terminal 44 and then transferred to terminal 45. The former connexion starts the motor through the contact 24, and the latter continues the motion through the contact 25, which has now left the insulator 28, but which will cause the motor to stop when again the insulator comes round. The motor drives the band through a shaft 6 which engages the rollers 3 or 4 according to which worm 7, 8 at the top and bottom respectively of the shaft is in engagement with its gear on the roller, the shaft 6 being movable vertically for this purpose by a lever 11.

Abstract: 952,613. Rollers. KIMBERLY-CLARK CORPORATION. April 14, 1960 [April 15, 1959], No. 13526/60. Heading F2U. [Also in Division D2] A drum, for use in a drier of a paper-making machine together with a doctor blade bearing on its surface, comprises a generally cylindrical shell made of a metal or alloy having a relatively low resistance to wear, in which the end portions only of the shell have annular surfaces made of a harder and more wearresistant material than the metal or alloy of the shell, so that the doctor blade is prevented from wearing down or gouging out the surface of those end portions. As shown in Fig. 7, rectangular plates of aluminium bronze are cut at an angle and then welded together to form parallelogram-shaped pieces. Several of these are welded together edge-to-edge, rolled into cylinder form and welded to form the shell 15. It is then heat-treated to reduce the differences in mechanical properties between the plates and the welds, and may be crowned. Circumferential grooves are cut near the ends of the shell, either before or after its formation into a cylinder, and filled with harder metal 61, e.g. welding metal or chromium, by welding or spraying, or rings of harder material may be slipped over the ends of the shell. As shown in Fig. 3, the shell so made is closed by heads 17 and mounted on a shaft 18. This shaft comprises two axially aligned, hollow sections 21 and 22 separated by a plate 23. Nozzles 26 are threaded into openings 25 in the plate and so distribute steam from the cavity 27 of the section 21 to the cavity 28 of the drum. Two scoops 29, mounted on pipes 30 collect condensate.

Title: Improvements in or relating to systems of control for electrically operated lifts
IPC: B66B1/44
Filed: 1935-05-08
Abstract: 456,729. Control of A.C. motors. EXPRESS LIFT CO., Ltd., Greycoat Street, Westminster, and STEVENS, R. J., 22, Millway, Duston, Northamptonshire. May 8, 1935, No. 13587. [Class 38 (iii)] The degree of energization of an eddy-current brake for decelerating an electrically driven lift, is controlled in accordance with the current supplied to the lift-driving motor during decleration. Upon operation of a switch SU, self maintaining relays B, U, are energized, the former shortcircuiting secondary circuit resistances ZF, ZG, ZH, of the driving motor ST, RO, and opening the circuit of one coil of an eddy-current brake X, and the latter connecting the motor to the supply. The relay B also shortcircuits a resistance ZA which is in one phase of the motor supply, and across which a potential is developed controlling the grid of a triode TR through which a second coil of the eddy-current brake is energized. A friction brake K is released and the motor starts. As it gains speed, a relay T, energized from a transformer Q connected to the motor secondary circuit, operates to energize a relay R. This relay inserts resistance ZJ in the circuit of the coil of the relay T and energizes a relay V which short-circuits further secondary existances ZC, ZD, ZE. The driving motor now runs up to full speed. As the lift approaches a floor at which stoppage is required the switch SU is opened, and, when an inductor relay W is operated by a zoning plate, the relay B is de-energized. Thus relays V, R, are de-energized, all secondary resistance is inserted, a coil of the eddy-current brake is energized and the impedance ZA is inserted in the primary circuit of the motor. The lift begins to slow down, and its primary current, which is a measure of the load on the motor, produces a corresponding controlling voltage on the grid of the triode TR. Thus the current flowing through the triode to the second coil of the eddy-current brake is dependent on the load of the motor so that the braking effect is modified and the deceleration-time curve of the lift rendered independent of the motor load. The lift speed reaches a low value, and, when the floor is reached, an inductor relay S is operated to de-energize the relay U to disconnect the motor and cause a friction brake K to be applied bringing the motor to standstill. In a modification, Fig. 4, not shown the impedance ZA and triode TR are replaced by a current transformer supplying an eddycurrent brake coil through a rectifier. The system is applicable to automatically-started lifts operating on the " collector " principle.
