摘要： 1,226,303. Friction gearing. KUGELFISCHER GEORG SCHAFER & CO. 19 Dec., 1969 [4 Jan., 1969], No. 62084/69. Heading F2Q. A friction roller for driving a spinning or twisting tube at high speed has drive surfaces 4, 4 1 of a wear-resistant resilient synthetic resin, e.g. polyurethane, which surfaces are machined while the roller is rotated at its design speed, e.g. 30,000-40,000 r.p.m., to ensure that they are truly cylindrical at that speed. As the material is not homogeneous, the surfaces are irregular when the roller is at rest, as shown at 4 111 of Fig. 4. A diamond tool is used for the machining. The roller is forcefitted on a spindle 1.

摘要： 1282820 Track systems BORGS FABRIKS AB 29 May 1970 [6 June 1969] 26106/70 Heading B7L In a track system in which the direction of movement of the carriage 8 may be reversed, two parallel tracks formed by secondary rails 1 and 2 and a primary rail 3 are connected by an outer arcuate rail 17 and a pivoted rail portion 5, the centre of the arc of 17 coinciding with the pivot axis 4 of the rail portion 5, the arrangement being such that the wheels 6, 7 on one side of the carriage 8 may be supported by the pivoted rail portion 5 while the carriage is driven, by chain drive 13, around the arcuate rail 17. A catch device 14, which may be controlled for example by an electromagnet, locks the rail 5 to rail 3 until the wheels 6, 7 are in position on the rail 5. Guide rails 9, 10, 16 are provided for guide rollers, Fig. 2 (not shown), of known construction on the wheels of the carriage. Fig. 3 (not shown) shows an embodiment in which the direction of movement of the carriage may be rotated through angles less than 180 degrees.

摘要： 920,453. Textile spindle drives; holding- down arrangements. SKF KUGELLAGERFABRIK G.m.b.H. June 3, 1960 [June 6, 1959], No. 19771/60. Addition to 783,935. Class 120 (2). In the construction of the parent Specification, the intermediate wheel 13 which transmits the drive to the wharve 6 1 of the rotatable and removable upper part 6 of the spindle from the driving-wheel 8 is carried by a bracket 11 which is movable by an operating member projecting outside a housing 4 which encloses the drive members to brake the part 6 or to free it for removal or both. In Fig. 1, the bracket is resiliently mounted at 10 and has an extension 11 1 which is urged by two springs, e.g. 14, at right angles to press a bevelled part 13 1 of a roller 13 against a corresponding part of a wheel 8 and against the lower part of the spindle 6 which constitutes a wharve 6 1 . The operating member is a lever 21 pivoted to a rod 19 secured to extension 11 1 ; when it is moved to the position shown, a cam part 22 engages the spindle rail 1 to move the bracket and hence the roller to interrupt the drive and move a detent disc 15 out of a recess 16 above the wharve. It may also move a bracket 17 carrying a brake shoe 6 1 . In another form, Fig. 3, the operating member is a handle 24 by which roller 13 and detent disc 15 may be disengaged; or the handle may have an extension with a cam groove on its lower face co-operating with a fixed pin so that as the handle is rotated the parts 13 and 15 are moved, and, if desired, a brake shoe on a bracket 17; as the handle continues to turn the brake shoe may be released to allow the spindle to be removed.

摘要： 908,113. Friction gearing. KLINGER MANUFACTURING CO. Ltd., GILCHRIST, R. S., and MATTINGLY, D. A. E. Oct. 12, 1959 [Nov. 25, 1958], No. 33210/59. Divided out of 908,111. Class 80(1). [Also in Group IX] In the apparatus for frictionally rotating and supporting a spindle described in Specification, 908,111, the spindle is retained magnetically. A horse-shoe magnet is disposed near the spindle and each of its poles is provided with fingers alternating and intercalated lengthwise of the spindle which has flanges opposite the various fingers, or the wheels of one set may alternate with magnetized discs (of smaller diameter) mounted on the same shaft and a corresponding number of peripheral flanges provided on the spindle adjacent the wheels or discs. The spindle may be of material such as ferrite having a high resistance to eddy currents.

摘要： 285,870. Schild, S. Feb. 24, 1927, [Convention date]. Cut-out arrangements.-Electrical systems, for example, the incoming lines L1, L2, the power transformers A, B, C and the outgoing lines L3, L4 are protected against fault by means of a maximum and minimum relay N which through switching mechanism K isolates all parts of the system on fault, and then reconnects them in sequence, and switches off the defective parts by means of a maximum current relay M. Upon removal of the fault, the defective parts are switched in again automatically. The switches which isolate the various parts of the system A, B, C, and A2, B2, C2, for example, are of the double coil type one coil when energized serving to close the switch and the other to open it. The energization of these coils from the battery D is under hand control by the selector W which determines which of the main switches shall come under the automatic control of the cutting-out and resetting controller K which is driven by the motor G when the voltage relay in one of the incoming lines assumes one of its closed positions due to increase or decrease of voltage. When, for example, the line L1 becomes live the contacts a, b of the relay N close and the motor G commences to rotate the drum. The connections of the drum controller to the main switches are such that the main switches in the system are closed in sequence. During this switching-in action, if a fault occurs in the next succeeding section (for example, between the switches A1 and A2) then the maximum relay M will operate and the main switch just closed will be opened again. In position 11 of the controller, it is stopped as the supply is automatically cut off from the motor G. If the voltage on the conductor L1 fails, for any reason, the motor is restarted and all the switches are switched off at position 13 of the drum. In position 14 the motor is again stopped and only on reappearance of voltage on line L1 is the switch mechanism again set in operation by the voltage relay N.
