Filed: 1921-04-09
Abstract: 182,896. Joel, H. F., and Joel, H. F. April 9, 1921. Armatures and field magnets, cooling; cores.- A fan structure and spacing separator for rotor and stator cores of dvnamoelectric machines is constructed in the form of a ring having a corrugated surface, or ridges and recesses. Fig. 1 shows a corrugated-ring separator S in position with the laminated core-plates A; the ring may be secured between two plates, and may be extended outwardly to support the teeth. Openings 0 are left in the end plates to admit cooling-air which is expelled at the periphery. The ring may be made of strip metal, corrugated and afterwards bent into the required form, or the complete ring may be stamped or cast. In bending a strip of metal into a circle, the recesses on the outer edge are made deeper than on the inner edge to allow for distortion. Fig 8 shows a construction suitable for armatures of large diameter. A strip of tape is perforated to admit the passage of air, and is then folded into sinuous loops F, C. In the form shown in Fig. 12, the two sides of the loops R are drawn together and extend upwards for the support of the teeth A. The bends G project inside the core and serve as air inlets from the ducts O. Fig. 15 shows a form in which the tape R has angular points which are bent upwards and downwards to form air inlets and outlets W. Twisted metal tape or woven or spiral wire may be used to form the corrugated ring. According to one of the Provisional Specifications the ridges of the type illustrated in Fig. 12 may be set at an angle to the radial line, or may be curved, and in a modified construction, grooved strips or tubes may be attached to the corrugated ring and extended between the teeth in the armature ducts.

Abstract: 1,172,851 Punches G. K. N. SANKEY Ltd. 27 Feb., 1967 [10 March, 1966], No. 10475/66. Heading B3W. A piercing tool comprises a punch retainer 10 having a bore 11 which receives the barrel 23 of a punch 12, a channel 17 along the bore receives a projection 27 on the punch and a counterbore 14 forms a shoulder 16 so that the punch can slide into the bore with the projection 27 in the channel 17 until the projection enters the counterbore and then the punch is turned to bring the projection over the shoulder where it is retained by a spring 28, endwise movement of the punch being also prevented by an abutment 18. The projection 27 is a ball-bearing cemented in position or a peg with a flat on one side to engage the shoulder 16. The spring 28 is a wire clip, one end 30 of which enters a hole 31 in the shoulder and the other end 34 of which is then i i line with the side of the channel 17 remote from the hole 31. A central portion 36 of the clip bows downwardly so that the distance between the underside of the bow and the shoulder is less than the diameter of the projection 27. When the punch is inserted and turned the projection deflects the bow which then returns to its natural position and prevents the punch falling out. To remove the punch, it is turned by a hand tool against the pressure of the spring bow until the projection 27 engages the limb 34, which aligns the projection with the channel 17. The spring may be a washer which has an upward bend in its periphery to receive the projection 27 when the punch is in its working position.

Abstract: 493,629. Control of several motors. JUHLIN, G. A., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. April 19, 1937, No. 11160. [Class 38 (iii)] In driving equipment for a plant including one or more main driving motors M and auxiliary driving motors E1, E2, the armatures of the motors E1, E2, are connected in series in a circuit which is in parallel with the armature of the motor M, the field windings of the motors E1, E2, are excited by or in accordance with the excitation of the main motor or motors, and a connection is provided between the mid-potential point of the supply source and the mid-junction point between the motors El, E2. The motor M may drive the main rolls of a rolling mill and the motors E1, E2 the edge rolls. The motors are supplied from a generator G the field of which is excited from an exciter Px through a controller C, and the field of the motor M is excited from an exciter Mx. The fields of the motors E1, E2, are connected in series and supplied from an exciter Ex having a field winding F2 carrying the excitation current of the motor M, and a field F1 energized from an exciter Sx excited in accordance with the armature current of the motor E2. The mid-potential point of the supply is formed by a choke CH connected to tappings on the armature of the generator G through slip rings, and its connection to the junction between the motors E1, E2, may be permanent or completed by a switch S. If the connection is permanent it may be made through a and where the switch S is employed it is closed while the motors E1, E2 are running up to speed, and opened either manually or automatically when the armature current of the motors El, E2 reaches a value indicating contact between the edge rolls and the rolled material. Thus the motors E1, E2, run up to speed in step but may take up slightly different speeds during working to allow for inequalities in the diameters of the edger rolls. Moreover, the speeds of the edger motors remain constant under varying load and bear a fixed relationship to the speed of the main motor. The choke CH may be replaced by a resistance.
