Title: Improvements in or relating to clutches
IPC: F16D13/08
Filed: 1922-03-07
Abstract: 177,156. Dortmunder Vulkan Akt.- Ges. March 18, 1921, [Convention date]. Clutches, friction.-In coil clutches for motor vehicles &c., of the type in which the ends of the coil are connected respectively to a driving or driven member and to an operating-member adapted to be coupled by an auxiliary clutch to the driven or driving shaft, too sudden engagement of the coil is prevented by providing a frictional drag between the driving or driven member and the operating-member. The operating- member may form an oil-tight casing. As. shown, the coil f is secured to a head k on a member a keyed to, say, a driving-shaft w<1>, and to a head i on an operating-member d, which, when engaged by a spring-pressed auxiliary clutch-member g slidable on a hub h secured to the driven shaft w<2>, causes engagement of the coil f with a driven drum e. The member d surrounds the part a, carrying frictional spring rings m, and is axially located with respect to it by a shoulder and by pieces c. A stop b secured to the member a contacts with one of the pieces c to prevent damage to the coil by unwinding in the event of accidental reversal of drive. The rings m serve also as packing when the casing d contains oil. The functions of the driving and driven shafts w<1>, w<2> may be interchanged.

Title: Glassware handling mechanism
IPC: C03B9/447
Filed: 1940-04-16
Abstract: 542,637. Glass manufacture. LANGER, G. B., and BRIDGES, J. R. April 16, 1940, No. 6879. [Class 56] Relates to a device for transferring a glass article from a mould of a forming-machine to another mould or to a conveyer or other suitable depositing-place. According to the invention, means are provided for steadying the article during its movement from the mould to the depositing-position. The invention is intended particularly for use with a rotary take-out device of the kind described in Specification 365,245 in which pneumatically operated grippers 47 are carried at the ends of a cross arm 36 that is rotated about a vertical shaft 33 in synchronism with the finishing-mould table 2 of a forming-machine. The steadying device comprises a carriage 78 which slides horizontally in guides in a housing 30 which rotates with the shaft 33. The carriage is reciprocated along its guides by two pneumatic cylinders 71 which operate in synchronism with the gripper cylinders. The carriage may be provided with two forked members to embrace the glass articles, but in the construction shown, two arms 85 are pivoted at each end of the carriage. Springs interposed between extensions on the arms tend to separate the arms of each pair, but as the carriage reaches each end of its stroke, the extensions of the arms make contact with an abutment 91 and cause the arms to close on the article. The movement of the carriage is so arranged that the arms close on the article in the mould 3 and prevent it from swinging while it is being moved to the depositing point. When it reaches the point, the backward movement of the carriage causes the arms to open at the same time as the grippers 47 release the article. The device may be used for transferring a parison from a parison mould to a finishing mould. A pneumatic cylinder may be arranged below the housing 30 to lift the whole mechanism periodically to lift the articles clear of the bottom plate of the mould 3 or clear of the parison mould. The device may be used without the grippers, in which case the arms 85 grip the article lightly.

Title: Improvements in and relating to protective cut-out arrangements for dynamo electric machines
IPC: H02H7/08

Abstract: 371,107. Protective cut-out systems. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Merrick, E. G. ; 1088, Waverly Place, Schenectady, New York, U.S.A.) March 5, 1931, No. 6915. Convention date, March 5, 1930. [Class 38 (v).] Dvnamo - electric machines, particularly synchronous machines. are protected against internal faults, e.g. a short-circuit of a portion of the armature winding, by a relay controlling the circuit interrupter and con nected to be energized in accordance with the relative values of the voltages induced ir two different pre determined numbers of field winding turns by the relative movement of the field winding and the short-circuited portion of the armature winding. In the arrangement shown in Fig. 1, where the four-part field winding structure 10 rotates in association with a fixed armature structure 11, the field winding is energized as a whole from the exciter 18 through the circuitbreaker 20 and the slip rings 15, 17. One winding 23 of a differential relay 22 is connected across the whole of the field winding and another (proportionally larger) winding 24 is connected across a portion only (for example one polar winding) through an additional slip ring 16. Both windings are connected through resistors 25 and normally they balance one another. On short-circuit of a portion of the armature winding, the high value of the E.M.F. developed in the single pole as compared with the small resultant voltage for the whole polar winding causes the relay to operate and trip the main circuit-breaker 13 and the exciter circuit-breaker 20. Instead of using a differential relay, a relay with one winding connected between the intermediate point on the field winding and a point normally of equipotential on a resistor or condenser connected across the whole field winding may be used. Such a relay may be of the dynamometer type with a second winding connected across the field winding. The resistor with a negative temperature characteristic and no time-lag such as is described in Specification 292,110, [Class 38 (iv), Electric supply and transmission systems &c.], may be used. The arrangement affords protection also against a breakdown in the field winding 10 producing an abnormal resistance distribution therein and operating the differential protection relay. In Fig. 4, D.C. losses in the resistor are avoided by using an impedance consisting of an inductance 31 and condensers 32. In this case an induction type sensitive relay may be employed.

Abstract: 764,738. Printing-telegraph receivers. SIEMENS & HALSKE AKT.-GES. March 11, 1955 [April 27, 1954], No. 7277/55. Class 40 (3) In a start-stop receiver having a first receiving magnet of which the armature releases the receiver shaft, a second receiving magnet of which the armature is explored by a number of levers at instants dependent upon the position of the receiver shaft, and a setting device for adjusting the interval between the instants of release of the receiver shaft and of the exploration of the armature of the second magnet by the first lever, the first magnet together with a locking device which is controlled thereby and co-operates with a projection on the receiver shaft is arranged to be moved relatively to the normal initial position of the receiver shaft. A coupling 4 connects the driving shaft 1 to the receiver shaft 5 carrying cams 22 associated with feeler levers 23 co-operating with the armature 24 of the second magnet 25. The shaft 5 carries a locking arm 6 having a projection 6a engaging, in the stop position, a projection on a locking lever 17. A plate 3 rotatable relatively to the axis of the shaft 1 and carrying a pointer 3a associated with a scale 26 on a fixed member 2, carries the first magnet 7. On release of the armature 8 by the start element, a detent 11 is rocked so that its projection 11a is moved clear of the end of lever 17 which is rotated against the action of a spring 28 to permit the shaft 5 to rotate. Towards the end of a revolution of the shaft 5, the projection 6a engages the curved extension 19a of an arm 19 connected to an arm 18 having an upper extension which lifts the armature 8 to its attracted position in which it is held by the stop element. The member 11 is retained by its spring 27 and the projection 11a latches the end of the lever 17 until the next start element is received. The operation of the receiver shaft relative to the incoming impulses can be adjusted by rotation of the plate 3 relative to the fixed frame member 2. In a modification, Fig. 2 (not shown), the release of the armature of the first magnet rocks a pivoted locking lever so that one end is moved clear of a notch on a pivoted detent having a tooth in engagement with a tooth on a cam on the receiver shaft which is set into rotation. Towards the end of a revolution a cam on the receiver shaft raises the armature to the attracted position in which the locking lever engages the detent member to arrest the rotation of the receiver shaft. The plate carrying the first magnet and locking mechanism has a toothed sector rotated by a gear-wheel on a manually rotatable shaft which can be locked in the adjusted position. In each of the embodiments the windings of the first and second magnets are preferably connected in series.
