[Also in Division H1] A stripline frequency changing arrangement comprises a strip transmission line conductor 18 having an input terminal 14 to which a source 12 of fundamental frequency f o  is connected, two earth-connected #/4 stubs 31, 32 in strip form disposed either side of the strip 18 and providing a band-pass filter for the fundamental frequency, a varactor diode 25 and movable tuning stub 26 for generating second harmonic frequency, two further #/4 stubs 33, 34 in strip form disposed on either side of the strip 18, these being open-ended and providing a band rejection filter for the fundamental frequency, and an output terminal 20 at which the second harmonic frequency is obtained. An isolator 10 diverts reflected energy to a load 16 so that it does not return to the source 12. In construction the strip 18 and stubs are integrally formed and are separated from earthed conducting sheets above and below by insulation (Fig. 2, not shown). The varactor diode is mounted on the upper sheet and is connected to earth through a variable resistor 30. The distances e, e 2  are selected to give maximum second harmonic power cut. The displacement of the opposite stubs may be from half to the full width of one strip and is selected to vary the width of the band pass (i.e. the frequencies f, f 2  in Fig. 5 (not shown)). The configuration of the stripline network of conductor 18 and stubs may be varied so that the stubs have right-angle bends (Fig. 3b. not shown).

Abstract: 980,266. Pumping liquefied gases. IMPERIAL CHEMICAL INDUSTRIES Ltd. Nov. 1, 1962 [Nov. 1, 1961], No. 39089/61. Heading F1A. A pump 1 draws liquefied gas from a storage vessel through pipelines 7, 2 and a coil 6 enclosed within a cooler 4. Pipeline 8 taps off liquid and passes it to the container 5 of the cooler and a float 12 maintains a constant liquid level. A valve 10 maintains the gas pressure in the container 5 below that in the suction main but above that in the distribution system, consequently the boiling temperature of the liquid in the container 5 is lower than that of the liquid in the pipelines 2, 7 and when the former evaporates it extracts heat from the latter. The container is drained by closing a stop valve 14 which allows the pressure therein to rise above that in the storage vessel and the liquid passes into a pipeline 13 containing a non-return valve 9.

Abstract: 1406202 Thermostats N KODAIRA AND M KUSUNOSE 23 Aug 1973 40005/73 Heading G1D [Also in Division G3] Apparatus in which a plurality of heating vessels 1, 1, 1 are simultaneously set to operate at the same constant temperature comprises a chamber 17 which contains fluid at a pressure controlled by a regulator 18-25, and which is connected to bellows 15, 15', 15". Each bellows is associated with a different one of the vessels 1, 1', 1" and acts on a lever in a direction opposite to that of a further bellows 6, 6', 6" connected to the respective vessel, the lever 7 being pivoted to actuate a micro-switch 11 in the circuit of a heating element within the vessel. In use, the heating element in each vessel is switched on until the vapour pressure in the vessel reaches a predetermined value. At such value, the pressure in the bellows 6, 6', 6" so balances the pressure in bellows 15, 15', 15" that the lever actuates the micro-switch 11 through the lever 7 to switch off the heating element. The temperature corresponding to the vapour pressure at which the heating element is switched off is regulated by adjusting the pressure in the bellows 15. This is effected by adjusting the air gap # between a manually adjustable lever 23 and a nozzle 21 connected to the chamber 17 which supplies the bellows 15 and which is supplied with gas under regulated pressure from a source 20 through a choke 19. When the temperature of any vessel drops, the associated heating element is automatically switched on again so as to restore and maintain the vessel at the predetermined temperature. In a further form, to cope with sub-atmospheric working pressures in the vessels, an exhausted bellows (27) may replace the spring 25, Fig. 4 (not shown).

Abstract: 1,150,770. Welding by pressure. AMERICAN MACHINE & FOUNDRY CO. 9 Sept., 1966 [21 April, 1966], No. 40328/66. Heading B3R. In welding two metal portions along a longitudinally extending seam the portions are held fixed with respect to each other with longitudinally extending parts adjacent and parallel, high frequency current is caused to flow in the parts to heat them to their softening temperatures and a mashing force is applied directly to the softened metal to weld the parts together. Two strips 20, 21, Fig. 1, which may be the ends of large coils, are abutted on a backup bar 23 and clamped by jaws 24, 24<SP>1</SP>, 25, 25<SP>1</SP> and electrodes 27, 28 connected to a high frequency, e.g. 4000-500,000 cycles/per sec. current source 26 engage the metal adjacent the seam line. A pressure roll 30 is mounted on a frame carrying the electrodes so that the frame may be moved along the seam or the workpieces may be moved relatively to the frame. The roll 30 may be used as a contact to replace electrode 28. The roll 30 presses the heated metal down against the backing bar so that the heated metal is confined by the abutting ends of the workpieces and becomes welded together. Conductive tabs 34, 35 may be provided to extend the current path and thus extend the weld seam to the end of the workpieces. A pair of fins on adjacent finned tubes may be welded. A wide cylindrical roll or a rounded roll similar to roll 30 may be used as a backup member. In welding a strip of steel to a strip of copper, each electrode is formed as a pair of contacts engaging both workpieces with the connecting lead to one pair of contacts extending over the copper strip to concentrate current in the copper strip. In an embodiment for welding a longitudinal seam 60, Fig. 14, in a tapered tube 61 for a lamppost &c., the tube is advanced past contacts 62, 63 and under a pressure roll 65 which reacts against a roll 66<SP>1</SP> located on a block 68<SP>1</SP> supported on a mandrel 74<SP>1</SP> within the tube. A roll 69 may be on the underside of the block. The block is held up in its proper position by a direct current magnet 75 adjacent the pressure roll 65. Induction heating may be employed.
