Title: Improvements relating to liquid-cooled electric machines
IPC: H02K3/24
Filed: 1921-11-22
Abstract: 172,015. Seidner, M. Dec. 29. 1917, [Convention date]. Dynamos, cooling; armatures and field magnets; conductors. - The cooling-liquid spaces for the rotor and stator of a dynamo are entirely separated from each other by walls appertaining respectively entirely to the rotor and stator, whereby the liquid applied to one member is prevented from coming in contact with that of the other member. Also, ducts are provided in the iron cores or in the substance of or among the conductors for passage of the liquid. As shown in Fig. 1, the rotor may be enclosed by end discs 7, 8 and a tube 4 in the air-gap, the stator being enclosed by a tube 3, end caps 1, 2 and a casing 62 having flanges 61 which define the overhang spaces 22, 23. The stator laminae have longitudinal holes 30, 31, Fig. 8, and may have recesses 28, 29 whereby the liquid, which enters at 49, Fig. 1, passes axially along the machine and radially, through spaces 33, to the outlet 52. In addition to passing in contact with the windings through the slot notches 28 the liquid may pass through borings or openings 39, Fig. 3, in the conductors themselves or through the interstices among the conductors or through tubes placed among the conductors in the slots. Alternatively, tubes of conducting or insulating material 45, 46, 47, 48, Fig. 2, may carry the liquid through the iron, these tubes making liquid-tight joints in the end-plates 11 and so preventing outward leakage between the laminae or from the slots where open slots are used. The rotor liquid enters and leaves through axial borings 53, 56 with offsets in the shaft. The complete tube 3, Fig. 1, may be replaced by two short end pieces 9, Fig. 2, these optionally being integral with the caps 16. The rotor construction shown in Fig. 9 comprises flanged end-pieces 57 enclosing spaces 24 from which the liquid flows through axial tubes or among the conductors which are buried in grooves 60 and axial tunnels. In the case of a synchronous machine, the cooling liquid of the outer member only is enclosed independently of the inner one which may be aircooled in known manner. The Specification, as open to inspection under Sect. 91 (3) (a), states also that each member ot the machine, may have two or more separate liquid-filled casings or shells instead of a single one, and the casing or casings may be so arranged as to apply the liquid only to those parts of the machine which require intensive cooling. This subject-matter does not appear in the Specification as accepted. Specification 113,627 is referred to

Natural gas issuing from a well head connected to inlet pipe 16 forms the dielectric of a probe comprising a rod 27 lying along the axis of the pipe 25. The rod 27 is supported by an insulating 'spider' 28 and electrical connection is made by a coaxial connector 29. The inner conductor 29b connects to the rod and the outer conductor 29a to the pipe 25. The probe is used to vary the frequency of a Clapp oscillator 32 situated in box 30 mounted on a table fixed to the pipe. The oscillator is connected via cable 20 to sensing circuitry where its frequency is compared with a reference frequency and any difference is detected by an F.M. discriminator whose output is displayed on a digital voltmeter. The oscillator 32 preferably works in the region 40-100 MHz.
