Title: Improvements in or relating to lasers
IPC: H01S3/06
Filed: 1965-03-26
Abstract: 1,039,213. Lasers. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 26, 1965 [April 10, 1964], No. 13069/65. Heading H3B. A laser uses the phenomenon of " double quantum stimulated emission " whereby an inverted population is stimulated to produce two photons of half the frequency of the photon normally emitted from the inverted population. A neodymium glass laser 2 producing stimulated emission at 1À38 microns lies between reflective surfaces 4, 6 and a dielectric mirror 16 having high reflectivity for 1À38 micron radiation. In the same cavity is a ruby laser 12 which normally produces radiation at 0À69 microns, but mirror 16 is arranged to be highly transmissive to radiation at this wavelength so that ruby 12 cannot lose in its normal mode. If the output of neodymium laser 8 is sufficient a threshold for double quantum emission from the ruby is reached, the cross-section for this process increasing rapidly as the light intensity increases above the threshold, giving an avalanche effect. A Kerr cell may be inserted between the neodymium laser and the ruby laser to increase the intensity of the neodymium laser output. In another embodiment two different ions are dispersed in a single host crystal, the frequency of the output of the first ion population, when inverted, being about half the frequency of the output of the second ion population, when inverted. The end mirrors may be plane or hemispherical. It is stated that gas lasers may be used.

Abstract: 552,726. Inner tubes for inflatable objects. FIRESTONE TIRE & RUBBER CO. Oct. 17, 1941, No. 13408. Convention date, Feb. 21. [Class 144 (ii)] A puncture-sealing inner tube for a pneumatic tyre or other inflatable object comprises a peripheral wall embodying circumferential corrugations crossed at least partially by a chain of protuberances, and a continuous tacky but normally non-flowing sealing layer on the inner surface of the wall beneath the tread. As shown, the inner tube is formed with circumferential corrugations 2 containing spirally arranged ribs 4 extending partially or completely around the tube. When the tube is inflated within its cover, the corrugations disappear, the rubber being placed under compression so as to seal up small punctures. The presence of the ribs 4 assists in venting air from between the tube and its cover during inflation and also in venting the tube during the moulding operation incident to vulcanization. The tube is rendered effective against larger punctures by a lining of sealing rubber 6 covering the whole of the interior or only the portion adjacent the tread. The inflation valve is provided with a tubular rubber extension 8 passing through the sealing layer.

Patent GB-135244-A (GB)
IPC: B23K11/06
Abstract: 135,244. British Thomson - Houston Co., (General Electric Co.). Oct. 18, 1918. Heating by electricity.-In a machine for welding metal sheets along a seam, the lower electrode is adjustably fixed and is shaped as a bar, along which moves a circular revolving upper electrode. There are means for changing the electrodes when worn, for automatically reversing and stopping the mechanism and breaking the electric circuit, for spacing and clamping the work, and for automatically raising the voltage. The lower electrode is an horizontal bar 29 seen in section in Fig. 3. The bar can be turned over when the upper edge is worn out, or a bar with four alternative edges may be provided. The bar rests on a wedge 27, and this again on a wedge 24, so that the electrode 29 can be raised or lowered by moving the wedge 24 perpendicular to the plane of Fig. 3, when it slides on the inclined ledges 23. To clamp the whole in position, the arms 16, with packing-members 28, are drawn together by turning the eccentric cams 19 on the ends of bolts 17<1>. The upper electrode comprises a frame 38, Fig. 1, bearing four removable disks 34, 36, &c and attached to the end of a travelling carriage 40, 41. The frame 38 is held against rotation by a spring plunger engaging in notches. At the end of the travel it is turned through 45 degrees automatically so as to clear the work, and it is then further turned by hand to put a fresh disk in position. A weight 66 provides welding-pressure. The bar 40 of the carriage is triangular in section and of heavy copper, and it is in sliding electric contact with a fixed triangular sectioned conductor. The electrode can be raised away from the work by turning the lever 67, the roller 69 of which engages under a rail 41 on the carriage, which is thus rocked about its right-hand end, Fig. 1. The carriage is integral with electrically-driven mechanism 42 which propels it, and which also, by means of a shaft 53, rotates the electrode disk 36 at a rate greater than that of rolling. The carriage 40 is set in motion from right to left by pulling the rod 87, which is connected to the gear-lever 76 and also to the switch that closes the primary of the welding-transformer 11. Motion is automatically reversed by the lever 92, which is first displaced by the tappet 98 and then returned by the weight 99 with sufficient force to push the gear-lever 76 through neutral to reverse. The return motion of the carriage is automatically stopped when the gear lever 76 is moved to neutral by collision with the fixed stop 90. The voltage is increased, during welding, by alteration of the angular relation of coils in a regulator. This alteration is performed automatically by linkwork actuated by the moving carriage.
