Title: Devices for Utilising Fluids under Pressure for Lubricating relatively Movable Elements.
Inventor: ABBOTT WILLIAM GEORGE
IPC: F16C32/06
Filed: 1916-05-10
Abstract: 101,671. Abbott, W. G. May 10, 1916. Spindle apparatus; driving - arrangements. - The contacting surfaces of two concentric rotating sleeves employed in spinning - spindle apparatus are lubricated or kept apart by a film of air, which, on escaping, is utilised for other work. An inner sleeve c supporting a bobbin e rotates and is also reciprocated by an arm f, and a sleeve b, carrying a rod h for winding the thread rotates between the sleeve c and a casing a. Compressed air enters by a pipe a<2> and circulates through annular grooves a<3>, b<3>, c<3>, b<4> and passages b<2>, c<2>. The air escapes through passages c<5> and nozzles k and serves either to rotate the sleeve c or to retard it. A part d supporting the sleeve c contains three cylinders and pistons d<1>, d<2> mounted on an eccentric stud p and forming either a motor or a pump. Valve ports n, m, Fig. 2, in the sleeve c communicate with the cylinders d<1>. The port n is connected to an annular groove opening at one part to the outside of the part d, and the port m is connected to a groove c<52> and a flexible pipe o leading to a valve chamber v and an outlet or inlet pipe o'. In winding the bobbin e, its speed of rotation is varied as it increases in size by the drag of the thread acting through an arm i<1> on the valve v. If the sleeve c is rotated by air issuing from the nozzles k, the pistons d<2> pump air through the annular groove c<52> to lubricate the bearing-surfaces, and through the pipe o, the outlet of which is obstructed so that the pump retards rotation of the sleeve. If compressed air is forced through the pipe o the pistons d<2> act as a motor to drive the sleeve c. In a modification, the valve v is in the circuit of the air that lubricates the sleeves a, b, and the issuing air acts on a piston controlling the radial position of a friction wheel on a disk, which form the driving-gearing of drawing- rolls controlling the feed of the thread.

Title: Improvements in magnetic powder and mouldings thereof
IPC: H01F1/24
Filed: 1948-03-06
Abstract: 650,583. Powdered cores. COMMUNICATION ENGINEERING PTY., Ltd. March 6, 1948, Nos. 7000 and 7001. Convention dates, March 10, 1947. [Class 38 (ii)] The individual magnetic particles used for moulded magnetic cores are coated with a water soluble alkali-metaborate, such as sodium perborate or sodium metaborate, prior to moulding in order to obtain consistent cores with low core loss. To every kilogramme of magnetic powder, such as carboxyl iron or hydrogen reduced iron, is mixed dry 30-40 grammes of sodium perborate, according to the permeability required. About 250 c.c. water is then added and the mixture thorougly stirred, and if required boiled for 15 minutes, so as to allow the oxygen liberated, when the perborate dissolves, to break up the individual magnetic particles and permit the sodium metaborate then formed to precipitate out on the individual particles and form an insulating coating thereon when the mixture is slowly dried out in a revolving mixer whereupon, in one process, about 35 grammes synthetic resin is added and the mixture treated in a ball mill prior to loading a heated mould operating at a pressure of 6,000 to 15,000 kg. per sq. cm. and temperature of about 100- 170‹ C. for 2 to 4 minutes. In the preferred process the sodium perborate added is between 30-100 grammes and the mixture is dried out in the revolving mixer at a temperature of 100‹ C. The mixture is then loaded into a mould operating at a pressure between 6,000- 15,000 kg. per sq. cm. and at normal room temperature. After ejection the mouldings are placed in an oven for 12-24 hours operating at a temperature between 120-180‹ C. and when withdrawn allowed to cool to 60‹ C. before coating with lacquer to prevent subsequent absorption of water.

Rotation of the sleeve alone, with the pin 12 removed, causes the sleeve and spindle to move longitudinally together with the port 4 and both cutters in unison, while rotation of both the sleeve and the spindle, with the pin 12 in position, causes movement as just described plus relative movement of the precutters 14 as the threaded port 13 turns.
