Title: Improvements relating to the field-regulation of dynamo-electric machines
IPC: B60L15/04
Filed: 1946-10-01
Abstract: 617,529. Exciting dynamo-electric machines. MATERIEL ELECTRIQUE S. W. Oct. 1, 1946, No. 29287. Convention date, Oct. 9, 1945. Drawings to Specification. [Class 35] [Also in Group XXXVII] A dynamo-electric machine has series or compound excitation and at least one of its field windings is subdivided into a plurality of elements which are adapted to be connected together in series, series-parallel, or parallel. Variable resistance is connected in one or more of the branches formed by the connection of the elements of the subdivided field winding or windings in parallel or series-parallel, the said branches having different characteristics. A series motor has two field coils of unequal strength which are connected in series for fullfield operation. At a first stage of fieldreduction the smaller coil is disconnected or short-circuited. At a next stage the two coils are connected in parallel with regulating resistances connected in series with each coil, and, at a last stage, the stronger coil is disconnected or short-circuited. If the series motor has three field coils, different stages of field regulation are provided by connecting two windings in series in one branch in parallel with a single coil in another branch, and then connecting all three windings in parallel, regulating resistances being provided in each case. In a modification, full-field operation for a series motor is afforded, as before, by connecting two dissimilar field coils in series, and a switching arrangement is provided to reverse one coil to connect it in series-opposition with the other. Subsequently, the opposing field coils are connected in parallel and each is provided with a regulating resistor. When two motors are used, a common resistor is provided to regulate corresponding elements of the two field windings.

Title: Improvements in or relating to spinning frames for yarns and the like
IPC: D01H1/36
Filed: 1930-10-01
Abstract: 355,994. Bunch-building mechanism for ring spinning- frames. RUSHTON, J. L., Kay Street Works, and HILL, H., Tarleton, Hill Cot Road, Astley Bridge, both in Bolton. Oct. 1, 1930, No. 29411. [Class 120 (ii).] In ring spinning - frames wherein a spindle drives a substantially vertical shaft coupled with the building-cam which actuates the ring rail by means of a lever and a system of chains and chain blocks, a bunching-cam is driven from the spindle and connected to one of the chain blocks to traverse the ring rail to wind the bunch, and clutch mechanism is provided automatically disconnecting the bunching-cam and connecting the normal building-cam when a predetermined length of yarn has been wound. The building-motion gearing comprises means for determining the position of the ring rail for the winding of the bunch. The heart-cam of the building-motion is driven through a clutch 33 and worm gearing 12 from a shaft 11, and a cam 30 adapted to oscillate a chain wheel 26 in the building-motion gearing to wind the bunch is driven through a clutch 32 and worm 27 on the shaft 11, the clutch forks 36, 35 being connected by a link 37 so that when one clutch is engaged the other is disengaged. The cam 30 oscillates the chain wheel 26 by means of a lever 47, which is coupled thereto for this purpose by a hand-operated locking-stud 55 and is connected by a link 56 with a measuring-motion adapted to operate an extension 62 of the clutch fork 36. The measuring- motion comprises a ratchet wheel 59 and integral therewith, a gapped disc 61 operated by a pawl 58 connected to the link 56, so that when the desired number of traverses has been wound, a stud on the extension 62 enters the gap 69 and the clutch 32 is disconnected and the clutch 33 connected, the normal building being thereupon started. Adjustment of the measuring-motion is effected by means of a stud 70, which is adjusted in holes 72 and, prior to the winding of the bunch, is set against the edge of a shield 67 for the ratchet. To determine the position of the ring rail for winding the bunch the bevel wheel 16 which actuates the heart cam is provided with a notch 73 to engage a pawl 74 when it is rotated by the operative by means of a spindle 81 to commence a fresh set. The Provisional Specification also describes a measuring-motion for determining the length of the bunch comprising a ratchet and slotted disc connected by a pin and slot constituting a lost motion device and by a spring, so that initially the spring is charged, and when the clutch fork handle is operated to release the pin from the slot in the disc the charged spring rotates the disc slightly, thereby preventing the pin from re-entering the slot when the handle is released. Specification 352,299 is referred to in the Provisional Specification.

Abstract: 1,007,474. Seals. T. E. C. HIRST. July 20, 1964 [July 25, 1963], No. 29480/63. Headings F2B and F2T. Sealing of a piston, a rotating shaft or a housing of an hydraulic or pneumatic device is effected by means of two split rings arranged side by side with their gaps offset relative to each other by the rings being prevented from angular displacement relative to each other either by having their adjacent faces locally bended, Fig. 3, or by an eccentric recess 16 in a face of one ring, Fig. 5, mating with a corresponding projection 17 in the adjacent face of the other ring. In Fig. 1, the split rings 1, 2 are positioned in an annular recess in a resilient annular member 6 retained on a reduceddiameter part 7 of a piston 8 by a member 11. In operation, fluid pressure in the cylinder 3 acts on the portion 12 of the member 6 which is thereby compressed axially and so forces the rings into contact with the cylinder. One of the split rings may have an inclined face, as shown at 18. In another embodiment, a pair of split rings is received by washers and screw and nut arrangement at either end of a resilient annular member itself mounted on a pistonrod to constitute a double-acting piston. In a further embodiment, the rings bear on a plunger-type piston and are mounted in a recess in the external surface of the resilient annular member which is retained in a recess at the end of the cylinder, the recess facing inwardly or outwardly of the cylinder. In Fig. 9, the rings bear on a rotating shaft and are retained within the resilient annular member 6.
