Abstract: 953,788. Cyclone separators. COLLECTRON Ltd., and D. SZEGO. Feb. 21, 1963 [Feb. 28, 1962; Feb. 13, 1963], Nos. 7843/62 and 5871/63. Heading B2P. In a dust separator of circular cross-section having a tangential inlet 24 for dust-laden gas, a clean gas outlet 19 and a dust collecting chamber 12, a peripheral layer of gas travelling upwardly through a sleeve 13 of circular crosssection is directed into an annular space 26 through a gap 27 provided between the sleeve and a tube 18 and having a cross-sectional area which decreases in an upward direction to create acceleration of the gas layer, gas being extracted from the space 26 by a fan 31 and returned to an annular space 25 closed at its upper end and extending downwardly beyond the inlet 24. The part 10 of the casing may be conical, as shown, cylindrical or downwardly dievrgent and convergent at its upper and lower ends respectively. The outlet 19 is tangential and is connected to a suction fan 22. The pipes 29, 33 are tangentially connected to the separator. The capacity of the fan 31 is about one-fifth to one-quarter that of the fan 22 and the velocity of the extracted gas entering the separator is greater than that of the dust-laden gas through the inlet 24. The lower end 23 of the tube 18 has a frusto-conical shape which permits adjustment of the area of the gap 27 by raising or lowering the tube, the area being preferably such that the gas velocity lies between 7,000 and 10,000 ft./min. and is between 1¢ times to twice the velocity of the clean gas through the entrance to the tube 18. Instead of the suction fan 22, the flow of the dust-laden gas may be induced by a pressure fan coupled to the inlet 24. In a modification, the casing part 10 has an upper cylindrical portion and the step 16 in the sleeve 13 is omitted. The gas extracted from the space 26 is returned to the inlet 24 through a nozzle mounted therein.

Title: Improved means for setting the hands of clocks by electricity
IPC: G04C11/06
Filed: 1927-03-26
Abstract: 268,772. Siemens & Halske Akt.-Ges. April 1, 1926, [Convention date]. Synchronizing.-The hands of an independent clock are set correctly over a circuit normally used for telegraphy. A relay 2 is coupled to the line 3 in parallel with a telegraph instrument 1 and, attracting its armature 4, completes the circuit through a retardation relay 8 when contacts 6 and 7 are closed by cams 11 and 12 operated from the clockwork. Contacts 14 and 15 are normally apart, and when the relay 8 attracts its armature 13 the latter engages under the lip 16 of blade 15 and raises it until the end of armature 13 reaches a slot in blade 15 and passes through on to the top of the blade. In its return spring-actuated movement the armature depresses the lip 16 and closes contacts 14, 15. During the same period a cam 19 closes contacts 17 and 18 and completes the circuit through a regulating magnet 22. The armature lever 23 has a pin 24 coacting with the lip 21 of an auxiliary slotted contact blade 20 as in the case of 13 and 15. Thus when the lever 23 is attracted contacts 17 and 20 are closed, providing a holding circuit for the magnet 22, whereas 17, 18 and 14, 15 are only closed momentarily. This contact 17, 20 persists until the end of lever 23 reaches the bottom of a recess 26 in the cam 19, by which time the correction of the hands has been completed.
