Abstract: 1,153,374. Refrigerators. AIR PRODUCTS & CHEMICALS Inc. 1 June, 1967 [3 June, 1966], No. 25251/67. Heading F4H. In a Joule Thomson cryostat, helium is passed in heat exchange relationship with a liquid nitrogen bath before liquefaction at a Joule Thomson liquefier, liquid nitrogen from the bath is passed in heat exchange relationship with helium from the liquefier, and a radiation shield surrounding the liquefier is in thermal contact with the nitrogen bath. As illustrated, helium is passed from a bottle 8 through an adsorber 13 to an adsorber coil 37 immersed in a liquid nitrogen bath 23. The helium then passes through a duct 62 (Figs. 1 and 2), filters 73 and adsorber 72, and a heat exchange coil 68 to a Joule Thomson orifice 71. The liquid helium reservoir so formed is in contact with a holder 46 for an article to be cooled. Helium evaporating from the reservoir passes in heat exchange relationship with heat exchanger 68, adsorber 72 and duct 62 to an exhaust duct 36. Ducts 48 and 49 connect a coil surrounding the liquid helium reservoir to the liquid nitrogen bath to establish a thermosyphonic flow of liquid nitrogen through the coil. An intermediate portion of the duct 62 is formed as a coil (Fig. 2) cooled by and surrounding a Joule Thomson arrangement operating with hydrogen as its working medium. The hydrogen is supplied from a bottle 7 through an adsorber 12 to anadsorber coil 36 immersed in the nitrogen bath. The hydrogen then passes through a duct 58, part of which is coiled, to a Joule Thomson orifice 67. Liquid hydrogen collects in a reservoir 61 and gas evaporating from the reservoir passes over part of the duct 58 and through a duct 57 to an exhaust duct 35. The hydrogen and helium supply and exhaust ducts 33-36 are in thermal contact in a coil 32 located in a vacuum space 31 surrounding the nitrogen bath. The vacuum space communicates with the interior of a removable casing 19 surrounding the Joule Thomson liquefier. A thermally conducting radiation shield 42 surrounds the Joule Thomson liquefiers inside the casing 19 and at its upper end contacts the base of the liquid nitrogen bath. The helium and hydrogen may be recirculated via connections 9 and 11.

P., 37, Radstock Road, Stretford, Manchester, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Sept. 4, 1934, No. 25467. [Class 35] In a directcurrent or like commutator machine with split brushes, an inductive impedance 16, preferably an ironcored choke, is interposed between one portion 14 of the brush and the junction point of the leads from the two portions. The winding 15 of a commutating - pole 3 may be interposed between the same junction point and the other portion 13 of the brush. In a two-pole machine the two inductances may be wound on a common core, the inductances being interposed in the leads of the corresponding portions (leading or trailing) of the two brushes. In a multipole machine the positive brushes are connected to a common lead and a common impedance and the negative brushes to a second common lead and impedance. The core of the impedance may be formed with an adjustable air-gap, to prevent saturation at peak load, and the value of the impedance may be regulated by a saturating winding. Fig. 3 shows an arrangement for this purpose. The core 20 is formed with an air-gap 21 and carries the impedance windings 16, 16<1> of a two-pole machine. It also carries a saturating winding 22 which is connected in circuit with the main field winding 24 and a rheostat 25. The exciting supply 24 is connected with a tapping on the rheostat 25 so that the saturating current is weakened as the main exciting current is strengthened and conversely.

Abstract: 636,534. Television; electric synchronous movements. FRANCE, H. G. DE. Aug. 29, 1946, No. 25963. Convention date, Jan. 26, 1942. [Class 40 (iii)] In a television transmitter, a power supply device which provides alternating current output fed to apparatus for supplying voltage to the valves at the transmitter incorporates means associated with apparatus for receiving a reference frequency in the form of electric oscillations and adapted to control the frequency of said alternating current output to a value which bears the same relation to said reference frequency as is borne thereto by the frequency of the alternating current supplied to the feeding devices for valves in one or more receivers adapted to receive the vision,signals from said transmitter. The arrangement may be such that the apparatus responsive to the oscillations at the reference frequency is at a receiver station. In the application of the invention to a television system having a movable self-contained transmitter unit, the carrier 3 and transmitter 12 are mounted on a car 1 and the voltage supply plant, carried by a trailer 2, comprises a motor 5 driving an alternator 6 through a generator 13 and an electric motor 14. The outputs from the alternator 6 and a receiver responsive to signals of the reference frequency, emitted by a lowpower transmitter 10 at a main station, are compared in a phase-meter 11 whose output is utilized to control the speed of the alternator 6 by modifying, for example, the carburetter control of the engine 5. In a modification, Fig. 2 (not shown), a thyratron discharge device is fed with direct current from a local generator and with sinusoidal current derived from the reference frequency in order to provide an output at the desired frequency which is fed to the voltage supply arrangement of the transmitter. The output from the transmitter 12 may be received on a receiver 18 or at a central station and re-radiated from a highpower transmitter 17. French Specification 869,107 is referred to, in connection with the control'of the motor 14 in response to the output of the phase-meter 11.
