Title: Refrigerant compressor
IPC: F25B31/02
Filed: 1974-12-19
Abstract: 1442557 Refrigerant compressors LENNOX INDUSTRIES Inc 19 Dec 1974 [27 Dec 1973]  54931/74 Heading FIN In a reciprocating refrigerant compressor comprising a compression mechanism 22 coupled to a motor 32 and mounted in a casing 11, a temperature sensor 50 responsive to the temperature of the compression mechanism prevents the motor from starting up when the temperature of the mechanism is below a predetermined value. Thus damage to the compressor is avoided due to operation with the lubricating oil in a highly viscous condition. The sensor 50 includes contacts (58) connected in series with the contacts of switches each arranged to prevent motor operation under adverse conditions. The switches include a highpressure switch which opens when the delivery pressure rises above a predetermined value; a lowpressure switch 90 which opens when the suction pressure falls below a predetermined value; a discharge temperature switch 100 which opens when the discharge temperature exceeds a predetermined value; and a motor protection switch 76 which opens when a detector 78 mounted in the motor windings 36 senses an excessive motor temperature. Each of the switches is connected to terminals leading into a control box 62 mounted on the top of the casing 11 whereby the connections between the switches are made within the box, Figs. 2 and 3 (not shown).

Abstract: 1382160 Electromagnetic-elastic wave transducer CHU ASSOCIATES Inc 27 Dec 1972 [27 Dec 1971] 59615/72 Heading H3U An X-band electromagnetic to elastic wave transducer comprises a structure 1, exposed to a steeply decreasing magnetic field profile A, and a bias field Hdc which may be axial, the two being equal in value at point P, contiguous regions R 1 , R 2 , R 3  having progressively increasing saturation magnetization, obtained by growing epitaxial layers, with increasing amounts of iron in YIG being replaced by Ga. The regions may alternatively be polycryatal iron or ferrite layers. The bias field is such that tunnelling of incident electromagnetic energy takes place, without any spin wave conversion, in region R 1 . At level P, conversion to spin waves does take place, the latter being transmitted with increasing frequency and decreasing amplitude to region P<SP>11</SP>, at which conversion from spin to elastic waves becomes possible, the elastic waves propagating into medium 2, of lithium ferrite, or YIG possibly doped with Ga, Mn, Mn-Ga or Eu. The layers R 1 -R 3  are in practice very thin. A converse elastic spin electromagnetic waves transduction takes place in structure 1<SP>1</SP>, exposed to steeply rising field C, and the bias field. Antenna structures 3, 3<SP>1</SP> comprise thin wires, or deposited strips, and may be extensions of the inner conductors of coaxial cables. The epitaxial growth is brought about by vapour deposition of an yttrium chloride, iron chloride, mixture at high temperature in a quartz tube on to a Gd-Ga substrate, or successive layers are built up by molten dipping. Typical dimensions, insertion loss, and delay time are given. A further medium (not shown) having a distinct saturation magnetization may be disposed adjacent medium 2 to produce the steeply decreasing magnetic field.
