Title: A method of repairing thick-walled enamelled castings
IPC: B23P6/04
Filed: 1950-09-15
Abstract: 674,599. Treating castings. BUZULUK, NARODNI PODNIK, and NOVOTNY, A. Sept. 15, 1950, No. 22703/50. Class 83 (i). [Also in Group XV] In repairing thickwalled enamelled castings by means of rivets of gold or other precious metal, a hole caused by corrosion &c. is machined to produce a cylindrical hole which is filled with lead driven in so that it reaches to about 1 mm. below the level of the enamel 4. Machining may be effected by dental or like tools to produce a hole 1 with a bottom groove 2. A hole 5 is drilled through the lead 3 to the cast iron 6 and widened at 7 to form a cone. A wax model 8 of the hole is then shaped to form a rivet on a steel pin 9 for withdrawing, and this is used to cast a corresponding gold rivet by lost-wax moulding in plaster and centrifugal casting. A copper ring 11, Fig. 7, is then put into the surface of the lead, the hole 5 is filled with pure water-glass and the gold rivet 10 is driven in.

A gas bearing is made of ceramic material and has highly polished " bearing " surfaces. In an embodiment, a sleeve 10 of ceramic material is mounted with clearance on a shaft 11 of ceramic material. The sleeve 10 carries an armature 14 of an electric motor, an extension 15 of which is provided for a pulley &c. to be affixed thereto. A housing 12 of the electric motor carries field windings 13 and is supported by the shaft 11. Axial movement of the sleeve 10 is restricted by retaining end thrust-washers 17, 18, which are attached to one end of the shaft 11 by a bolt 16; and by a thrust-washer 19 located between the other end of the sleeve 10 and the housing 12. The thrust-washers are made of ceramic material. The " bearing " surfaces are extremely smooth, the finish being no greater than twenty R.M.S. micro-inches; and are free from flaws of more than 0À01 inch in cross-section. The ceramic composition consists of 91 to 98% by weight of alpha alumina crystals and at least 2 to 6% by weight of a refractory glassy matrix. The alumina crystals are no greater than 150 microns in any dimension and 98% of the crystals are within the range of 0À5 to 40 microns. The glassy matrix consists of silica with alumina and magnesia distributed randomly therethrough. The ceramic material is compacted to a density of at least 89% of the theoretical maximum density.
Patent GB-149920-A (GB)
Title: Improved apparatus for starting single-armature converters from the alternating current side
IPC: H02K47/08
Filed: 1920-08-06
Abstract: 149,920. Akt.-Ges. Brown, Boveri, et Cie. Aug. 16, 1919, [Convention date]. Rotary converters.-Consists in a device for starting a rotary converter as an asynchronous motor on a tapped alternating voltage and changing automatically to full line voltage only when the converter is at synchronous speed with correct continuous-current polarity. When the switch a is thrown to the left, the alternating side of the converter b, c takes a reduced voltage from taps on the line transformer d, and a contact l energizes the closing-coil e of the switching-device g, h. By means of a contact g this completes the exciting-circuit : i of the converter, which then energizes the coil f. If the converter polarity is correct, the coils e, f co-operate, but if it is wrong, they oppose and the contacts g, h are opened. The contact h energizes, through a transformer k, the coil m of a time relay, the time element n of which is so adjusted that closure of the contact o requires a considerably longer interval than that normally required for bringing the converter to synchronism. When the coil m is not energized, the relay armature immediately drops to its initial position. Thus, if the coils e, f co-operate, the contact o is closed when the converter has reached synchronism and the magnet p throws the switch a to the full voltage position. If the alternating supply volts are below normal value and the converter accordingly cannot reach synchronism, the contacts g, h only open and close repeatedly without permanently connecting the converter to the line volts until they reach their full value.

Title: Improvements in and relating to laster apparatus
IPC: H01S3/098
Filed: 1964-06-04
Abstract: 1,055,398. Lasers. HUGHES AIRCRAFT CO. June 4, 1964 [June 24, 1963], No. 23237/64. Heading H1C. In a laser, Fig. 1, comprising an active medium 13 such as a ruby rod and an optical resonator formed by reflecting surfaces 17, a particular mode of oscillation is preselected from the plurality of oscillation modes within the frequency range selected by the resonator. To this end the reflecting surfaces are appropriately curved and one surface is silvered only at the regions where the required mode or modes emerge. In a modification, Fig. 5, detached reflectors 21 are used and an opaque screen 23 suitably apertured in the shape of the desired mode pattern is placed between the active medium and one reflector. The position of the reflective regions in the embodiment shown in Fig. 1 is determined by the steps of (1) lapping the ends of a ruby rod to form end curvatures corresponding to the desired transverse mode, (2) evaporating silver on to the end surfaces, (3) exciting the active medium by a non- uniform pumping field 19 and examining photographically the mode patterns at the emergent end of the ruby rod during laser action very close to threshold pump power, (4) varying the pump energy distribution around the periphery of the ruby until the desired mode pattern is obtained, and (5) removing, e.g. by etching, the silver from one end surface of the rod except where the required modes are located. Removal of the unwanted silvering on one of the reflecting surfaces may be effected by depositing photo-resist on the surface and exposing it while the laser is operating in the desired mode. Subsequently the unexposed portion of the resist and underlying silver is removed. Fig. 2A to Fig. 2C show the regions where transverse modes emerge for one, two and three electromagnetic field lobes respectively. The non-uniform pumping field may be provided by the use of an elliptical reflector or by placing adjustable opaque strips between the pumping source and the active medium.

A scraper elevator 37 is supported in the mouth of a scraper bowl 12 by at least one arm 47, the arm 47 being releasably connected to the elevator by means, e.g. hinges 52, 49, that does not permit pivoting of the elevator relative to the arm in a vertical plane and by a second coupling, e.g. a ball and socket connection 53, to the bowl so that it can be swung vertically. The arm or arms 47 is or are so pivotally mounted on the vertical side wing or wings 31 of. the pivotable bowl bottom 31 that the second couplings 53 of the or each arm is above the pivotal connections 32 between the wings and the sides of the bowl about which the bottom is swung during and after ejection of the contents of the bowl. Thus as the bottom is swung rearwards during ejection of material the elevator is swung forwardly so that discharging material does not jam against the elevator.
