Abstract: 265,255. Powell, W. H. Sept. 8, 1925. Windings.-A multipolar dynamo-electric machine has an armature wound with a lap winding and a wave winding, the wave winding forming equalizing connections for the lap winding and being wound distinct from or forming part of the lap winding. Fig. 2 shows a portion of the armature winding, four lap-wound coils 45, 55, 56, 57 together with four wave-wound coils 52, 58, 59, 60 being connected to commutator segments 1, 5. The location of the lap and wave coils with regard to the field poles A - - H is symmetrical, that is to say, the four lap coils are disposed in relation to the poles A, B while the four wave coils are similarly disposed in relation to the remaining poles. Between equipotential points, for example between segments 32 and 8, lap coil 61 and wave coil 64 are equalized. The slot pitch of each winding may be equal and full pitch, or it may be equal and short pitch or one may be short pitch and the other long pitch. The lap winding may be simplex or multiplex, and, for example, if the winding is triplex, the wave winding is nine times re-entrant and interconnected with the individual lap windings. The number of circuits through the armature is equal in the case of both windings. If the lap winding has a forward pitch the wave winding has a backward pitch and vice versa. The wave winding may be distinct, or, as shown in Fig. 7, the coil sides c, d, c', d<1> may form portions of the lap and wave windings combined. A formula, relating the number of windings, slots, coils per slot, and pairs of poles is given. Specification 150,752 is referred to.

Abstract: 1532487 Automatic exchange systems INTERNATIONAL STANDARD ELECTRIC CORP 1 June 1976 [6 June 1975] 22577/76 Addition to 1483273 Heading H4K In a modification of the system of parent Specification, which discloses a TDM system wherein speech samples are switched in senal bit format via a space switching stage comprising a plurality of planes, with successive speech samples being routed in turn to successive ones of said planes, the transmission of each speech sample through a plane is controlled by clock pulses of such a frequency that the sample transmission time through the space switching stage is at least one time slot less than a number of time slots equal to the number of planes. In the prior arrangement there were four planes and the speech samples were clocked though the space switching stage at 2Ás per sample i.e. 4 system time slots. In the present embodiment five switching planes are provided but the same transmission rate of 4 system time slots is used. Hence there is a free period of one system time slot between two samples passing through the same plane and this provides adequate time for the alteration of the settings of the crosspoints of the plane. To enable speech samples relating to the same connection to always be switched by the same plane, the number of planes should be a submultiple of the number of system time slots per frame.

Abstract: 485,904. Oscillographs. RADIOAKT.- GES. D. S. LOEWE. Aug. 21, 1936, No. 23059. Convention date, Aug. 23, 1935. [Class 37] [Also in Groups XL and XXXV] In an arrangement for producing an impulse at the passage of an alternating voltage through zero, the voltage is applied to the deflecting plates of a cathode-ray tube, the beam of which is focused by an electronoptical system and impinges in its undeflected position upon one electrode and in any deflected position upon a second electrode. The alternating potential is applied to a pair of deflecting plates 4, 4<1> of a cathode-ray tube 3, so that when the potential is zero the beam is undeflected and strikes an electrode 5 or passes through an apertured diaphragm and strikes a plate electrode or a wall coating behind the diaphragm. The impulses generated every time the potential passes through zero may be used for starting a relaxation oscillator for synchronizing and other purposes, particularly in connection with television systems. The Specification as open to inspection under Sect. 91 comprises also the use of the impulses produced each time the alternating voltage passes through zero to trigger off a discharge tube or a pentode and the device may be used for obtaining synchronization impulses in television transmitting or receiving arrangements. In a modification, the electron beam in its undeflected position passes through an apertured diaphragm and falls on a fluorescent screen at the end of the tube, the periodic fluorescence of which affects a photo-electric cell which generates impulses. This subjectmatter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specifications 344.315, 366,053, and 379,812, [Group XL].
