Title: Improvements in methods of and apparatus for controlling electrically operated windlasses
IPC: B66C13/26
Filed: 1927-07-08
Abstract: 299,488. Eck, R., and Gõbel, F. A. R. July 8, 1927. Driving-gear for winches. - Electrically-controlled windlasses driven by three-phase asynchronous motors in conjunction with a balancing gear are arranged so as to obviate the necessity of starting the motors under load. In one arrangement, shown in Figs. 1 and 2, one motor l drives a sun-pinion l<1> while the other k drives external teeth on the wheel h. At starting, the two motors are run under no load at equal speeds in opposite directions and under these circumstances no rotation is transmitted to the shaft d carrying the planet pinions and to the winding drum a. One or other of the motors is then slowed down to allow the winding drum to turn slowly in one direction or the other. Finally the slowed drum is reversed to give full hoisting-speed. Where a hanging load is to be raised, an electromagnetic brake e acts on the shaft d until the motor takes up the load. Fig. 3 shows a modified form in which both motors k, l drive sun-wheels and the planets i', i<2> are keyed to a shaft mounted in the wheel b geared to the drum In this case no rotary movement is imparted to the wheel b and the drum so long as both motors run in the same direction at the same speed. Smoothness in working is caused by arranging that the slowing-down action of the drum k shall be performed against the torque of an auxiliary motor s.

Title: Improvements in or relating to information storage arrangements
IPC: H04J3/12
Filed: 1964-05-04
Abstract: 1,016,111. Digital data-storage. SIEMENS & HALSKE A.G. May 4, 1964 [May 3, 1963], No. 18356/64. Heading G4C. [Also in Division H4] A temporary data-storage arrangement comprises a plurality of first level buffer stores each capable of storing in series a number of words which is less than the maximum possible number of words in a group of words that may be applied to a store, a lesser plurality of second level stores, even less third level stores and so on, the arrangement being that when a first level store is full, a second level store is seized and that when this is full a third level store is seized and so on and that when a word is read-out of the first level store, the words in this store are " moved-up " one position so as to fill the just-vacated storage position whereby the lower level stores are emptied as soon as possible and may thus be seized by other first level stores. The arrangement is used in an S.T.D. telephone system where a large number of stores must be provided for receiving dialled digits but wherein it would be uneconomic to provide each store with sufficient storage positions to hold the maximum possible number of digits that may be dialled by a subscriber. Consequently the first level stores have just sufficient storage positions for storing digits in respect of local calls, the lower level stores being seized as required in respect of trunk calls.
