Abstract: 870,808. Cooling electric motors. GARRETT CORPORATION. Feb. 13, 1958 [Feb. 14, 1957], No. 4774/58. Class 35. [Also in Group XXVI] In a refrigerator motor-compressor unit, the motor is cooled and lubricated by means of a combined refrigerating and lubricating fluid, a small amount of which is bled off from the main circuit into the hollow rotor shaft, from whence it escapes through small radial orifices and returns through the motor air-gap. The refrigerant may be dichlorotetrafluorethane (Registered Trade Mark " Freon 114 ") containing 1.0-0.1% lubricating oil. Refrigerant used for cooling the motor is drawn from a supply tube 81, passes through a porous bronze filter 75, and then up through a metering orifice 72 into the hollow rotor shaft 36. It then passes into the motor body through holes 83, 84 adjacent the bearings. That emerging from the upper holes 84 cools the stator in passing axially down through the air-gap and slot mouths. The spent coolant is returned by duct 95 to the inlet 26 of the compressor. The compressor comprises two rotor stages 13, 14 sealed respectively by labyrinths 32, 35, and is isolated from the motor body by a seal 55.

Specified fibres are wool, cotton, ramie flock bast, glass wool, asbestos, rayon, polyamide, polyester, acetate, polyacryl nitril and polyvinyl chloride. When inflammable fibres are used these may be rendered flame-proof or ignitable only with difficulty by preliminary treatment with flame-proofing agents. Specified bonding agents are natural rubber; synthetic rubber such as butadiene acrylonitrile or butadiene styrene; polyvinyl chloride, polyvinylidene chloride, acryl methacrylic acid esters, polyvinyl acetate and polystyrol. Specified flame-proofing agents are dispersions with a basis of antimony trioxide, colloidal silicic acid, polyvinyl chloride, chlorinated rubber, or chloroparaffins; reaction products of urea and melamine formaldehyde resins with phosphorus-hydroxy-halogen compounds; reaction products of phenol resin and phosphoro halogen compounds with ammonia: bromided allyl phosphate polymers; urea phosphate condensation products; a condensation product of a melamine formaldehyde precondensate with tetra-hydroxyphosphonium chloride; a precondensate of urea dicyanodiamide formaldehyde. Impregnation may be effected by immersion or by applying the impregnating mixture as a foam. The impregnating mixture may be in the form of a dispersion or emulsion in water or an organic solvent or mixtures of organic solvents with one another or with water. The flame-proofed webs may be subjected to aftertreatment with flame-proofing agents, for example, by padding.

An adjustable wedge-head apparatus for straightening automobile door openings &c. comprises a fork 2 connected to a yoke 4 which is rotatably adjustable relatively to the fork, and a pair of pressure pads 6, 8 pivotally connected to the yoke. As shown, the fork has a screw-threaded bore for connection to a thrust member (14), Fig. 4 (not shown), and a hexagonal mounting pin 26 for the yoke. The pin passes through hexagonal passages in the fork and a twelve-pointed aperture 24 in the yoke so that the yoke may be fixed in a number of different positions to divide the thrust as required between the pads 6, 8, which are faced with rubber &c. Alternatively, a friction coupling may be used affording an infinite number of angular settings between the yoke and fork, or free pivoting may be provided by a cylindrical pin. A flat spring 60 aligns the pads before use, and abutments 54 limit their movement. To permit lateral pivotal movement of the pads, pivot pins 46 for the pads pass with clearance through holes in the yoke which is located with clearance between lugs 42 on the pads.
