Abstract: 462,499. Filters. MABAG MASCHINENUND APPARATEBAU AKT.. GES., and 'NEUROTH, F. April 8, 1936, No. 10286. [Class 46] Apparatus for the separation of water from liquid fuels comprises a filter of bath sponge 4 which will retain water. The sponge is disposed between perforated discs 2, 3 and the disc 3 is attached to a rod 10 which is moved to compress the sponge when required to express water therefrom. The fuel enters by a pipe 5 and passes down a pipe 6 to a basin 7 where most of the water remains out of the line of flow of the fuel. The fuel passes up through the filter to an outlet 8. The rod 10 may be moved by a rack 11 and toothed wheel 12 and may be periodically operated by clockwork or from external mechanism such as the starter mechanism or motor of an aircraft. The water is automatically removed from the basin 7 by a float 14 operating a valve 15. The discs 2, 3 may be in the form of grids or woven wire. In another form of filter for use when filling aircraft tanks, the fuel rises through the sponge filter and passes out down a central pipe which is movable and connected to one of the spongeretaining discs to compress the sponge. In another form, the sponges are held in a cage interchangeably disposed in the filter chamber. A grating forms the top of the cage and is moved by a hand wheel and screw spindle to compress the sponge. A liquid level gauge is provided to record the height of water in the discharge basin. Specifications 15330 /88, [Class 46], and 422,748 are referred to.

Abstract: 1,134,895. Feeding webs. BRITISH INSULATED CALLENDERS CABLES Ltd. 8 March, 1967 [9 March, 1966], No. 10394/66. Heading B6B. [Also in Division B8] Apparatus for regulating the tension of a tape 1 drawn from a web-roll 2 which is mounted for rotation against a constant braking torque, comprises two parallel non-rotatable pins 5, over and under which the tape passes, the pins being mounted on a rotatable base 4. A spring- loaded control arrangement comprises a spring- loaded pivoted arm 8 carrying a dancer roller 11, which arm has a quadrant gear meshing with a gear on the base 4. The arm 8 pivots in response to variations of web-tension and to variations in its spring loading so as to control the angular position of the base 4 and therefore the web tension. Since a constant braking torque is applied to the web-roll, by, for example a brake band (26, Fig. 10), as the webroll diameter decreases, the web tension will tend to increase. To overcome this problem, the spring loading of the pivoted arm 8 is made variable. Interposed between the loading springs (49, Fig. 10) and the pivoted arm 8 is a cable (52) and a cam (51). The profile of the cam is derived mathematically to accommodate the change in web-roll diameter. As the pivoted arm 8 moves, thereby rotating the cam (51), the force exerted by the springs to the cable (52) via the cam is varied. The apparatus is used in a machine for lapping tape helically about a longitudinally advancing core.

Title: Improvements relating to safety devices for protection against fire
IPC: A62C35/60
Filed: 1929-04-06
Abstract: 324,582. Etablissements Sipro. Nov. 30, 1928, [Convention date]. Sprinklers, automatic; fires, preventing in connection with doors and ventilators; gas, cutting off in case of fire.-In a thermal device for operating safety fire appliances, such as sprinkler valves, gas pipes, doors, or ventilators, of the kind in which a heat sensitive contact maker controls, through the intermediary of a relay, a motor which operates the appliances in both directions, that is, to render them active in case of fire and to return them to normal inactivity when the fire has been extinguished, a normally contracted wire 2 closes a contact 3, 4 in a circuit in which is a relay 14. The relay 14 closes a main circuit, in which is an electric motor 11, at either of two contacts 16, 17 according as the circuit at 3. 4 is closed or open. The current passes through the stator 13 of the electromotor in one direction or the other according to the position of a reversing switch 15 controlled by the position of the appliance, for example a valve 8. Normally, the contact, 16 is closed, and the switch 15 is at contacts 20, 21. No current then passes through the stator. When the wire 2 expands, the relay 14 breaks the main circuit at 16 and closes it at 17. Current now passes through the stator, and the rotor 12 opens the valve 8 through bevel gears and a screw 9, until a lug 22 on the latter moves the reversing switch 15, through a linkage, 25, 26, to open the main circuit at 20, 21 and close it at 18, 19, when again no current will pass through the stator. This condition persists until the wire 2 cools and the relay 14 closes the circuit at 16. Current now passes through the stator 13 in a direction to close the valve 8. When the latter is fully closed, the lug 22 moves the switch 15 to the contacts 20, 21, and current ceases to pass through the stator. Specification 309,120, [Class 47 (i), Fire-escapes &c.], is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a construction, Fig. 1 (Cancelled), in which the thermal contact 2, 3, 4 controls an electromagnet 5 which in turn controls an electromagnet 6 which opens or closes the valve 8 according as it is energized or de-energized. In another construction, the relay controls cocks which fill and empty a cistern, the weight of which when full, opens the valve 8. In another construction, the relay controls the supply of pressure fluid to a piston, movement of which opens or closes the valve. This subject-matter does not appear in the Specification as accepted.
