Abstract: 1375724 Discharging liquid by fluid-pressure L G ERICKSON 4 Oct 1971 46146/71 Heading F1R [Also in Division F2] A self emptying hose comprises an inner hose collapsible along substantially its whole length; an outer conduit surrounding the inner hose, the length of each of the hose and conduit being many times greater than its transverse dimension; means coupled with the hose and the conduit for sealing the junctions between the ends thereof, and a mass of compressible fluid within or in fluid communication with the interior of said outer conduit and the exterior of the inner hose sufficient to collapse the inner hose along substantially its entire length to force substantially all the fluid there from when the fluid-pressure in the inner hose falls below said fluid-pressure of said source to thereby empty the inner hose. As shown in Fig. 1 the source of fluid-pressure in the intermural space may be derived from an auxiliary tank 13. In this embodiment the distended inner hose completely fills the outer conduit. To ensure that all the liquid in the hose is expressed when emptying a smaller diameter substantially non-collapsible perforated tube 16 is inserted within the inner hose to prevent formation of trapped pockets of fluid. Likewise a similar perforate tube 17 is provided in the inter space to ensure even gas distribution during emptying or filling of the inner hose. The tubes 16, 17, may be replaced by internal projections on hose and conduit to prevent total collapse or filling respectively. As shown in Fig. 3 the inner hose, when distended, does not fill the outer conduit. The auxiliary tank may thus be dispensed with and the pressure source stored in the inter space 22. The device (s) employed to prevent the accumulation of liquid pockets in the inner house may be omitted at one end whereby a shut-off valve action may be achieved at that end. The hose and conduit may be of nylon reinforced plastics. A particular application is in emptying irrigation hose prior to repositioning the hose.

Patent GB-1551220-A (GB)
Title: Ultrasonic flowmeter
IPC: G01F1/66
Filed: 1975-11-20
Abstract: The device for measuring the rate of flow of a fluid comprises two sound transducers, of which one is arranged upstream and the other is arranged downstream in the fluid or is coupled acoustically to the latter. The sound transducers (16, 17) are designed for transmitting and receiving ultrasound, and form a phase-locked loop together with a voltage-controlled generator (23) and a phase detector (21). The rate of flow of the fluid is determined from the difference in the resonant frequency of the phase-locked loop when sound is radiated in and against the direction of flow of the fluid. As a result, the measurement result is independent of the speed of sound in the fluid and independent of slow changes in the frequency-determining parts, in particular of the generator (23) of the device. <IMAGE>

Title: Improvements in and relating to Conveyors
IPC: B65G47/26
Filed: 1967-10-20
Abstract: 1,150,974. Conveyers. RAPISTAN Inc. 20 Oct., 1967 [20 Oct., 1966], No. 47741/67. Heading B8A. Movement of articles along a conveyer track is controlled by means which incorporates a time delay between the sensing of an article and the response of the control means. Thus the control means does not respond to the natural flow of articles but only to an unusual condition resulting from the cessation or substantial slowing of the articles. Rollers 12 of a rollerway 10 are driven by a belt 13 which is normally urged into engagement with the rollers 12 by pressure rollers 14. Pivoted hangers 15 for the rollers 14 are arranged in groups, the rollers of each group being raised by a pneumatic actuator 19 which receives air pressure, via a valve 31, from a conduit 32 common to all the actuators. An adjustable air bleed port (33), Fig. 3 (not shown) is -provided between each valve 31 and actuator 19. The valves are normally open, the actuators operated and the rollers 14 raised to cause drive by the belt 13. Sensing rollers 47, 47a, 47b control the valves 31 but each valve controls the actuator which is next upstream in the direction of movement of the conveyer. Thus, sensing roller 47a controls the position of the pressure rollers 14 of group B and sensing roller 47b those of group C. As shown, an article F has depressed roller 47b and the associated valve 31 has been closed. Since the article has remained on the roller 47b longer than a preset interval, e.g. from 2 to 5 seconds, escape of air through bleed port (33) causes the actuator 19 to retract and the belt 13, supported on rollers 14 of groups C, is allowed to drop. There is accordingly no drive immediately upstream of the stalled article. An article passing over a sensing roller at normal speed allows the roller to rise before the actuator responds to the closing of the valve 31.
