The switch TC may be a triac or a pair of oppositely connected thyristors and the lamp units are grouped in sections 1, 2 of an airfield lighting system. The lamps are supplied with current via transformers T connected to a constant current regulator. By applying a trigger voltage between cables 4 and 5 or 4 and 6 the triacs in the section 1 or 2 may be rendered conductive to short circuit the lamps in that section. The cables 5, 6 may be joined and supplied with an A.C. control voltage in phase with the transformer supply voltage.

Abstract: 950,538. Spraying apparatus. TROCKENTECHNIK G.m.b.H. Feb. 2, 1962 [March 22, 1961], No. 4053/62. Heading B2B. An apparatus for spraying liquid on pieces of leather 4 spread on a conveyer belt 3 and carried thereby to a drier, includes a plurality of fixed spray guns 13 arranged above the belt and distributed over its width, which guns are controlled directly by switches located in front of the guns and switched on and off by photoelectric cells or lever arms responsive to the passage of the pieces, the free ends of the lever arms having on and off positions of which at least one is below the path of the pieces. Pneumatic delay elements are arranged between the switches and the operating means of the spray guns. Each spray gun may be associated with two switches and the spraying ranges of adjacent guns may overlap. In Fig. 3, the switch 9 in carrier 5 over which the leather passes, is actuated by lever 12 controlled by air nozzle 7 such that when no leather is passing over carrier 5 the lever 12 is depressed and the switch 9 is in its "off" position, and when leather is passing no air reaches lever 12 and switch 9 is in its "on" position operating the corresponding spray gun 13. In Fig. 4, roller 16 is mounted pivotally on frame 18 by lever 17 which lever 17 actuates switch 9 into the "on" position when a piece of leather pushes the roller 16 out of the groove 15 in carrier 14. If the pieces of leather are very thin or short they may be passed on to belt 3 by belt 22, Fig. 6, consisting of individual strips between which the nozzles 7 blow air to actuate switches below belt 22 as described in the embodiment shown in Fig. 3.

Title: Improvements in or relating to process for sweetening hydrocarbon oils
Inventor: KRAUSE JACK HARRY
IPC: C10G27/08
Filed: 1952-02-21
Abstract: Mercaptan-containing hydrocarbon oils are sweetened by intimately contacting them, in the liquid state, with a catalyst consisting essentially of an inert adsorbent material, a copper salt as hereinafter defined and at least about 8 per cent. of water, at a temperature between about 190 DEG  and 230 F., and in the presence of free oxygen.  The copper salts employed are copper sulphate or a water-soluble copper sulphonate which is chosen from copper alkane sulphonates with not more than 10 carbon atoms in the molecule and copper aryl sulphonates in which those having alkyl substituents on the aromatic nucleus do not have more than a total of 8 carbon atoms in the alkyl substituents.  Hydrocarbon oils mentioned are petroleum distillates such as naphthas, kerosene, Diesel oil, furnace oil and heater oil.  The inert adsorbent material may be Fuller's earth, attapulgus clay, silica gel, act vated carbon or alumina.  Copper sulphonates mentioned are copper benzene sulphonate, copper toluene sulphonate and copper sulphonates obtained from a mixture of methane, ethane, 1-propane, 2-propane and isobutane sulphonic acids.  In an example, the hydrocarbon oil is washed with caustic soda to remove hydrogen sulphide and then passed through a rock salt filter to remove traces of caustic soda.  The oil is then heated to 190-230 DEG F., saturated with water, and mixed with air or commercial oxygen.  A slurry of catalyst and hot oil, the catalyst consisting of 72 per cent. by weight of Fuller's earth. 8 per cent. of copper sulphate and 20 per cent. of water, is then pumped in and the mixture allowed to settle.  The oil is decanted, washed with water, cooled and finally passed through a salt filter.  The catalyst may be revivified by addition of water to the spent catalyst-oil slurry and contacting this with oxygen.

Trip arms 35 mounted on vertical shafts 38 are interconnected and control the movement of a face cam 53 swinging on the shaft. 38 to rock a lever 45, 46 against the urge of a spring 44. The rollers 10, 11 are latched down in working position against the pressure of a spring 52 between the brackets 39, 51 by a pin 48 on the lever 46 engaging a notch 49 in the bracket 51. An obstruction in the way of the arms 35 deflects the latter and the lever 45 is moved by the cam 53 to unlatch the bracket 39 from the bracket 51, allowing the rollers to be swung upwards clear of the bed by the spring 62 until the pin 48 engages a notch 50. The trip is reset by hand depression of the rollers. The plungers 7, 13 for effecting the cut leaf to a removing means 8 is depressed against the pressure of a spring 54 through levers 13, 14 from a cam on the shaft 19.' An obstruction between the parts 8, 7 causes the spring 54 to give.

Title: Improvements in or relating to torpedo depth control gear
IPC: F42B19/04
Filed: 1942-04-10
Abstract: 556,645. Torpedoes. WHITEHEAD TORPEDO CO., Ltd., and JONES, L. April 10, 1942, No. 4776. [Class 9 (ii)) A depth-control gear comprises a spring-urged plate, a diaphragm exposed to sea-water pressure and a pendulum, both plate and pendulum being connected to the valve of the depth-steering engine through the diaphragm, and is characterised by having the pendulum connected directly to the diaphragm but over an area considerably less than that of the spring- urged plate so that the sensitiveness of the pendulum mechanism for correcting angular inclination is greatly improved. The plate 5 is urged against the diaphragm 4 disposed in the bulkhead 1 of a chamber 2 by a spring 6, and its hollow stem 13 contains a slidable member 11, a spring 15 and a sleeve stopl8 The member 11 is integral with a stem 16 and a plate 12 of less area than the plate 5, and the plate 12 is attached to the diaphragm by a nut with an extension 24. This extension is attached to a lever 20 connected at one end to the piston-rod 26 of the depth-controlling valve, while the member 11 is connected to the rod of a pendulum 8 adapted to vibrate between stops 9. When the torpedo is running at the correct depth according to the spring setting, any slight variation up or down will be corrected by the movement of the pendulum causing movement of both plates and the valve control. If however the torpedo is not running at the correct depth, the pressure of the water on the diaphragm is too small or too large, and the plate will be moved to the'right or to the left with corresponding movement of the valve control. Moreover, if the depth is too great by a considerable amount, the diaphragm is pressed inwardly against the resistance of the spring and the valve is moved to full nose-up position, and to prevent this movement assuming extreme proportions, the pendulum then acts against the pressure of the inner spring 15 to move the member 11 and the inner plate against a smaller water resistance estimated by the reduced area of the inner plate only, with a corresponding movement of the control valve. Extreme movement of the pendulum is prevented by the member 11 coming against the sleeve stop 18 and then pressing against a water resistance represented by the area of the main plate. In a modification, the diaphragm is horizontal and the pendulum and the nut extension 24 are connected to the member 11 and the valve-control rod, respectively, by cranked levers.
