Title: Lubricant separation and recovery systems in refrigerating machines
IPC: F04D29/06
Filed: 1964-08-05
Abstract: 1,069,678. Refrigerating. CARRIER CORPORATION. Aug. 5, 1964 [Sept. 26, 1963] No. 31860/64. Heading F4H. [Also in Division F1] Lubricant deposited on the walls of an inlet conduit of a centrifugal compressor is collected and transmitted to a lubricant sump under the action of a jet-pump operated by part of the gas discharged by the compressor. As shown, a motor-compressor unit 10 comprises an impeller 12 rotating in a casing 41 and an inlet conduit 23 the end of which extends into the suction line 22. Adjustable vanes 24 in conduit 23 together with the impeller 12 cause the incoming gaseous refrigerant to undergo a swirling motion so that entrained lubricant and liquid refrigerant are deposited on the walls of conduit 23 from which they pass to a chamber 46 through a gap 48 between conduit 23 and casing 41; lubricant and liquid refrigerant collecting on the wall of the suction line 22 pass through a gap between the suction line and the end of conduit 23 into a chamber 42 and thence to chamber 46 through an aperture 49. The liquid refrigerant is vaporized by the heat of compression transmitted through casing 41 and returns to the compressor inlet through gap 48. The compressor discharges into an annular space 28 from which part of the compressed gas passes through a line 56 to a nozzle 60 discharging into a Venturi section 61 to induce a flow of lubricant from chamber 46 and through a compartment 59 and a conduit 50 to a lubricant sump 52. A vent line 58 communicates the space above the sump with the suction line. An electrically operable valve may be provided in line 56 and opened intermittently under the control of a a float responsive to lubricant level.

Abstract: 604,549. Styli. DICTAPHONE CORPORATION. Nov. 26, 1945, No. 31915. Convention date, March 19. [Class 40 (ii)] The "point" of a stylus consists of an edge which is the intersection of two cylindrical surfaces. Fig. 10 shows a jewel positioned for use with a leftwardly moving recording surface of the type in which the groove of the lateral displacement type, is embossed. The jewel has four plane faces, two of which are visible in Fig. 10, the intersection of the front and rear left-hand faces being ground to form part of a cylinder R.C of small radius and the intersection of the right-hand faces A.C. The intersection T.I. of the right and left-hand faces, as is seen in Fig. 11, which is a view looking perpendicular to the line 11-11 of Fig. 10, thus consists of two mutually inclined straight lines connected at the bottom by a curved edge which is the intersection of the two cylinders. The inclinations of the plane faces and the radii of the respective cylinders are so chosen that the whole of the .intersection lies in one plane which is perpendicular to the record for the desired angle of presentation A.P between the jewel axis JA and the vertical O-Y. To avoid partial obliteration of the track by the recession face, the recession angle R.A should be not less than the approach angle A.A.

Abstract: 855,043. Rolling screw-threads. GROB, E. Oct. 8, 1958 [Oct. 9, 1957], No. 32156/58. Class 83 (4). In thread-rolling machines in which the threads are formed by profiled grooved rolls as the workpiece moves in an axial direction, any errors which occur in the thread pitch of the workpiece are corrected by alteration of the angle between the axes of the rolls and the axis of the workpiece. Each grooved roll 17 is mounted in a holder 16 on an arm 8 which is seated on a bushing 4 rotatable by a worm 6 operated by a hand wheel 7. At the end of the arm 8 is mounted an adjusting motor 11 which through a worm 12 and rocking lever 14 swivels the holder 16 about the axis 15 of the bushing 4 to correct errors in the thread pitch of the workpiece W. The correcting motions of the holders 16, 16<1> are positively coupled in opposite directions, e.g. by a sun wheel (not shown). The motor 11 is operated by an electrical control device (not shown) actuated by contacts 26 engaged by feelers 25 upon movement of a sprung template 19 secured to a thread gauge spindle 18 which is coupled to the workpiece and is shifted axially by amounts corresponding to the errors in the thread pitch thereof. In another form axially-inclined grooved rolls are seated in brackets which are swivel guided in holders by the adjusting motor through'worm gearing. The rolls are drawn in at one of their ends such that when the angle between the axes of work and rolls is increased the rolls produce a thread of larger pitch in the workpiece. In a modification a single contact feeler 37 is used to control the adjusting motor.
