Title: Improvements in or relating to optical maser elements
IPC: H01J3/06
Filed: 1962-09-27
Abstract: 1,012,344. Optical masers. WESTERN ELECTRIC CO. Inc. Sept. 27, 1962 [Oct. 3, 1961], No. 36675/62. Heading H3B. The active medium of an optical maser is formed by a thin film 13 in the form of a cylinder on a crystal 11 of lower refractive index. As shown, the thin film 11 which is only a few wavelengths thick extends to the edges 12 of the crystal 11 which is coated with mirror surfaces 14 but it is stated that the crystal 11 may extend beyond the film and be provided with cooling fins to form a more efficient heat sink. The crystal 11 may also be hollow to allow it to be cooled by air or water. The mirror surfaces 14 of the thin film do not need to be as accurate as in the case of solid laser crystals as internal reflection at the surfaces of the film 13 does not produce a large number of possible modes because of the thinness of the film 13. The crystal 11 may be sapphire and the thin film 13 may be ruby. The ruby film may be grown on a sapphire crystal or a sapphire crystal may be doped to produce a ruby film.

Title: Improvements in or relating to nuclear reactors
Inventor: ROBBINS ERIC JOHN
IPC: G21C17/04
Filed: 1961-10-17
Abstract: 939,714. Nuclear reactors. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. Sept. 18, 1962 [Oct. 17, 1961], No. 37159/61. Class 39 (4). A method of detecting leaking fuel elements in an operating nuclear reactor cooled by carbon dioxide under pressure and containing fuel elements each enclosed in a protective sheath containing a gas inert to the fuel members and reactor components, comprises sampling the coolant gas before and after it enters the fuel channels, amplifying the inert gas concentration in the samples with respect to the coolant, and comparing, by means of a mass spectrometer, the inert gas concentration of the samples. The inert gas is preferably helium 4, but may be helium 3, neon or krypton, and about 1.5 cm.<SP>3</SP> of helium 4 per fuel element is sufficient for detecting leaks. Before the samples are taken, the coolant pressure may be reduced abruptly, e.g. by about half an atmosphere, or the temperature of the fuel elements may be reduced by varying the speed of the blowers used to circulate the coolant. Amplification of the helium may be effected by absorbing the carbon dioxide into an absorbent such as soda-lime and by absorbing impurities in liquid-nitrogen-cooled charcoal.

Abstract: 827,044. Welding by fusion. REVERE COPPER & BRASS Inc. Nov. 28, 1957 [Aug. 15, 1957], No. 37188/57. Class 83 (4). [Also in Group XI] An arc welding gun is adapted to make an internal weld between a tube 7 and one side of an apertured plate 5 while positioned on the other side of the plate. The gun consists of a handle 25 with a trigger switch 29 attached to a cylindrical casing 23 which in use is pressed against the plate 5. Rotatably mounted on anti-friction bearings 33 within the casing 23 is a housing 35 carrying an insulating block 45 and having a portion 81 of reduced diameter carrying a collar 83 adapted to fit within an aperture in the plate 5 to locate the gun. A non-consumable electrode 17 is clamped by a rod 73 having a threaded end in a tube 51 mounted in and adjustable longitudinally of the block 45. A conductive sleeve 57 on the tube 51 rotatably holds a conductive block 89 and a pipe 117 is brazed in a groove in the sleeve. Cooling water is passed through the pipe 117 which also serves to conduct welding current from a cable 127. Shielding gas is supplied from a pipe 95 through passages and annular grooves to a space between the rod 73 and the tube 51 and escapes through holes 107 in the tube 51 and an aperture 87 surrounding the electrode. The electrode 17 and block 45 are rotated by a worm-wheel 37 secured on the housing 35 and driven by a worm and flexible shaft drive, the gas and water pipes and the block 89 remaining stationary. The welding is automatically controlled in response to the trigger switch 29 by the control system described in Specification 824,586. The sheet 5 is formed with annular projections 11 prepared as shown in Fig. 11 for the welding operation.

Title: Improved process for the catalytic isomerisation of olefins
IPC: C07C5/25
Filed: 1963-09-27
Abstract: Double bond shift in aliphatic olefins without skeletal rearrangement is effected in the presence of boron phosphate at 50-300 DEG  C. The catalyst may be used alone or mixed with kieselguhr, silica or alumina.  The low temperatures favour the production of internal from alpha-olefins.  The process may be applied to n-pentenes, methylbutenes, n-hexenes, methylpentenes, ethylpentenes and other C7 and C8 olefins.  In the examples: (1) gaseous butene-1 is converted at 250 DEG  C. to butene-2; (2) a butene-butane mixture is treated at 250 DEG  C. to increase the butene-2 content; and (3) 2-methylpentene-1 is treated at 80 DEG  C. to obtain 2-methylpentene-2.

Title: Apparatus for continuously effecting automatic bobbin exchange on spinning machines
Inventor: NISHII MASAHIKO
IPC: D01H9/10
Filed: 1964-04-06
Abstract: Automatic doffing and donning apparatus for a spinning machine comprises a carriage movable along the row of spindles, and donning and doffing units each comprising an endless belt with a p  plurality of cop grippers and means for successively lifting the grippers of the doffing unit and for lowering those of the donning unit, the endless belts both being driven in the same direction at a speed which offsets the movement of the carriage so that the cops and filled bobbins carried thereby remain stationary relatively to the spindles while donning and doffing take place.  The donning and doffing units.  In Fig. 1 (not shown) a carriage A moving in the direction shown carries donning and doffing units Bm and Cd each comprising upper and lower endless belts driven in the direction shown and each carrying slotted members 15, 31.  In each of these slides a member 19, 34 comprising a pair of jaws spring-urged together, the rise and fall of the members being effected, as the carriage moves, by curved tracks 55\sv, 56\sv. The slides are positioned to correspond with the spacing of the spindles, and the carriage and belts move oppositely at equal speeds, each member thus remaining stationary relatively to the spindle to which it is attending throughout the donning and doffing operations.  In the case of a doffing unit, as a member 19 reaches its lowest point CP, a slide-block D is projected, Fig. 5 (not shown), to detach a bobbin from its spindle and raise the bobbin into the grip of the jaws.  As the carriage continues to move, the bobbin is raised successively through positions CP\sv, CP\yF until it is completely freed from its spindle finally the jaws are opened as one of them strikes a member 59 to release the bobbin.  On the donning side, each member 34 holds a cop which is gradually lowered on to the corresponding spindle. Donning is complete when the member reaches its lowest point, the spring urging the jaws together being of such strength that it releases the cop as the member begins to move upwardly again.  There is provision for raising the units clear of the spindles when the carriage is returned to the other end of the machine.  In Fig. 6 (not shown), another form of apparatus is shown when the belts are inclined and the tracks 55\sv 56\sv are dispensed with.
