Title: Improvements in and relating to dynamo-electric machines
IPC: H02K3/12
Filed: 1947-08-07
Abstract: 632,255. Dynamo - electric machines. SPERRY GYROSCOPE CO., Inc. Aug. 7, 1947, No. 21717. Convention date, June 20, 1945. [Class 35] The stator and rotor of a Selsyn are wound with a series of windings having different numbers of poles such that the output of the secondary windings comprises a series of voltages which undergo different odd numbers of cycles of variation, i.e. the normal single cycle plus third, fifth and seventh harmonics, for each revolution, the sum of these voltages rising sharply from zero to a maximum value as the rotor is turned through a small angle from the zero position. The windings for each number of poles are wound on a stator and rotor having a suitable number of poles, the rotors being arranged on a single shaft. Alternatively, all the windings may be wound into the slots in the cylindrical surface of a single stator and rotor. The voltages appearing at one of the stator or secondary " phases " whose axis is coincident with the axis of the rotor on energization of the primary winding with a single phase voltage, are shown plotted against rotor displacement in Fig. 15. The two-pole winding produces a voltage curve 22 which is shown substantially sinusoidal ; the six-pole winding is arranged to produce a voltage wave 29 of lower amplitude but of three times the " frequency " ; whilst the ten and fourteen pole windings produce voltage waves 38 and 49 respectively. The sum 50 of these waves, shows a sharp rise from the neutral position 0 to a substantially constant maximum value. In Fig. 20 which shows a circuit connection for the Selsyn, the transmitter stator windings 65, 66, 67, 68 are wound for two, six, ten and fourteen poles respectively, and are energized by corresponding single phase rotors 69, 70, 71, 72 fed from a supply 73. The receiving stator windings 61, 62; 63, 64 are correspondingly connected and energize the series connected rotor windings 74, 75, 76, 77, the pole numbers corresponding to those of the transmitting windings. The voltage due to relative displacement of the machiness appears at terminals 78, 79 and is of the form shown in Fig. 15. Winding diagrams are given showing two and three-" phase " stator windings.

Filed: 1960-06-21
Abstract: 927,228. Inductive potentiometers. E. M. LANGHAM, and COLVERN Ltd. June 15, 1961 [June 21, 1960], No. 21753/60. Class 38 (2). [Also in Group XXXVI] A potentiometer in which voltage steps in the output are reduced by using a multiple take-off member, having the pitch of the takeoff points differing from that of the turns or tappings of the inductive or resistive winding with which they co-operate (either conductively or capacitatively) to give a vernier effect, has circulating currents between the take-off points inhibited by applying equal voltages between adjacent take-off points such that the voltage between the outer take-off points is substantially equal in magnitude and phase to the voltage between the turns or tappings of the winding which they span. In the embodiment shown in Figs. 2, 3, 4, rod 21 is a former of high magnetic permeability carrying a sectionalized winding 22, the winding being of a good conductor. The identical sections of winding 22 are connected as shown in Fig. 4 to the secondary 235 of transformer 23. The sleeve 25 carrying coaxial windings 27 and 18 surrounds windings 22, spanning more than one section. The pitch of winding 28 is different from (preferably smaller than) that of winding 22, and resistors 30, 31 joining the ends of winding 28 are such that the voltage per unit length is the same for windings 22 and 28. Resistive contact, represented by resistances 35, is made between windings 22 and 28, as the latter slides on the former. An input voltage VI is applied to the primary 23P of transformer 23, of which another winding 23T is connected to winding 27 which is inductively coupled to winding 28. The output VO is taken between the junction of resistors 30 and 31 and the free end of winding 23S. In a modification, resistances 35 are replaced by capacitive coupling, by interposing a dielectric between windings 22 and 28, or constructing these of anodized aluminium. In another embodiment, using the circuit of Fig. 5, capacitive couplings used, the capacitor elements being strips embedded in dielectric plates, at right angles to the direction of relative motion.

Abstract: 773,463. Bending glass sheets. GOOLD, L. L. (Libbey-Owens-Ford Glass Co.). July 28, 1955, No. 21764/55. Class 56 In the bending of glass sheets, particularly pre-cut flat blanks for deeply curved vehicle windshields, the flat sheet 12 is first placed on a support 66 well above the closed sectional mould 14, 15, all in the positions shown in chain lines in Fig. 7. The support is carried by elbow links 56 which are pivotally secured to other links 53 which themselves are carried by a cross shaft 46 to which the end section 14 is connected by arms 47, the shaft 46 being carried by links 18 pivoted at 43 to the stationary frame. On manually releasing the supporting means the weight of the glass causes the linkages to move to the full-line positions of Fig. 7 thereby opening the mould, the glass sheet now acting as a strut. As the sheet sags into the concavity of the mould. the linkages move from the full-line position of Fig. 7 to that shown in Fig. 6 and in this position the ends of the glass sheet are in contact with the mould end sections 14, the supporting means 66 having moved to below the top surfaces of the sections 14.

Filed: 1956-07-13
Abstract: 799,572. Automatic exchange switches. SIEMENS & HALSKE AKT.-GES. July 13, 1956 [July 15, 1955], No. 21812/56. Addition to 797,913. Class 40 (4). In a switch of the type described in the parent Specification, enclosed contact sets passing through the holding winding and the operating winding parallel thereto are provided for the purpose of energizing the holding winding. In one embodiment, Fig. 2, each of the cross-point contact sets 1, 2, 3 associated with the intersections of a vertical column coil RS and the horizontal row coils ZS1 ... 3 includes contacts s1 ... s3 connected in parallel for energizing the vertical hold coil HS. In a second embodiment, Fig. 3, there is provided a separate contact set s arranged to be operated when the column coil RS and a control coil SS are energized and subsequently to be held by the holding winding HS. The control winding SS may be common to a number of columns or individual to the contact set. The control winding SS may be independently energized, Fig. 4 (not shown); connected in series between the row and column coils, Fig. 5 (not shown); connected in parallel with the row or column coils, Figs. 6a, 6b (not shown); connected in series with the row or column coils, Figs. 7a, 7b (not shown); or may comprise two windings, one connected in series with the row coils and one in series with the column coils, Fig. 8 (not shown). In the case where individual control coils are they may be connected in series with their associated column coils, Fig. 9 (not shown). Provision is made for ensuring that simultaneous operation of a column coil and the corresponding hold winding does not result in false operation of contacts whose row coil is not energized. To this end the holding coil is provided with two oppositely poled windings HW, KW. In one method of connection, Fig. 10, when the energization of the row and column coils RS, ZS results (either immediately or eventually) in the closing of the contact s, the coils HW, KW are energized in opposition, thereby having no effect. When the contacts ek open, KW is disconnected at the same time as RS and the coil HW remains energized to hold the connection. In a second method of connection the coil KW is connected up by an auxiliary contact s2 operated at the same time as s1 energizes HW. The coils KW may instead form part of the column winding with similar effect. In another arrangement, Fig. 12, the winding KW is connected up immediately to provide reverse flux, but the horizontal coil ZS is as dimensioned that when energized its field over-rides that of KW to cause contact closure in conjunction with the column coil RS. The connection is subsequently held by the energization of HW over contact s.
