Abstract: A pilot operated relief valve (16) includes a non-flowing modulated pilot valve (20) and a main valve (122). The pilot utilizes a torsion device (52) in connection with transducers (56, 58) and valves (136,140). The transducers (56,58) relate variations in pressure within 10 the valve system to the torsion device (52). The torsion device (52), in turn, acts to open and close various ports (84,114) of the pilot valve (20) so as to achieve modulated relief of overpressurized fluid from a pressure system. In addition, the torsion device (52) can be manipulated to provide for easily achieved and accurate set pressure positions.

Title: Interrogation and remote control device.

IPC: H04B7/26
Filed: 1989-05-18
Abstract: Said device (AFG) comprises two separate partial devices (A, B) interacting through antenna arrangements (1, 11). The first partial device (A) includes a high-frequency generator (4) for producing a carrier frequency, a high-frequency line (3) leading to the antenna (101) and a high-frequency demodulator (56). The latter includes a directional coupler (5) and a detector diode (6), both connected upstream from a discriminator and signal-processing unit (8). Power is supplied to said partial device (A) by a supply unit (58). The second partial device (B) includes a high-frequency direct current converter (14), a voltage-controlled resistance (16), a modulator (62) and a signal transmitter (19). Four-wire networks (102, 112) make the antenna arrangements (1, 11) self-resonant as regards carrier frequency; said arrangements are located in each other's near fields. The carrier frequency emitted by the first antenna (101) is received by the second antenna (111) and converted to direct current (i). The signal (S) produced by the signal transmitter (19) modulates the direct current (i) by means of a corresponding subcarrier frequency (f), resulting in an absorption modulation which retroacts on the first antenna (101) and on the high-frequency demodulator (56). The latter delivers the corresponding subcarrier frequency (f), from which the discriminator and signal-processing unit (8) derives an output signal (SS) corresponding to the signal (S) emitted by the signal transmitter (19). Said device can be used wherever signal transmitters which cannot be accessed by direct transmission, in particular measuring probes, are to be interrogated, for example in the case of signal transmitters implanted in living organisms.

Abstract: A support vehicle in the form of a tractor (16) carries a main fixed frame (8) on which is arranged an intermediate frame (7) the height of which can be adjusted by means of a cylinder (10). The intermediate frame supports, by means of two hydraulic cylinders (121) symmetrical about their common articulation (13), a support beam (5) on which are arranged, near each end, sensing devices (26) each with two staggered sensing contacts (21-24). Also arranged on the support beam (5) is a spraying device (6) with a row of spray nozzles (9) which spray a treatment fluid. Each pair of sensing contacts, (e.g. 23, 24, 211, 212), detects the height (c) of the support beam (5), and hence of the spray nozzles (9), above the ground (1) or envelope surface (4) of the crops (3). The measurement current, which flows through the plants and enters the ground, is drawn from the battery (18) of the vehicle, the negative terminal of which is earthed and the positive terminal of which is connected via the control unit (32) to the sensing contacts, which are connected by earth current circuits to the tyres (19). The more accurately the distance (b) above the crops (3) is maintained, the more uniform and hence the more efficient are the spraying operations.

Abstract: A commercial message timer (110,112,114) stores data indicative of a first tuned station in response to a channel change command and begins repeatedly timing a predetermined time period. Upon each expiration of the time period, the user is reminded that the commercial message on the first tuned station may be over. In this way a user can avoid a commercial message on a first channel by setting the timer and scanning through other channels, and yet be reminded to return (e.g. by use of a PC (previous-channel) key (208)) to the first channel at the end of a time period substantially equal to that of a typical commercial message. In another embodiment employing a videocassette recorder (VCR) the commercial timer is activated upon pressing the PAUSE key (207) of the VCR so that the user may avoid recording the commercial message on videotape.

Abstract: A blood reservoir (10) is formed with a hard outer shell housing defining at least one blood compartment. A flexible bag (60) is mounted in the outer shell and is connected to the reservoir inlet port to allow blood to directly enter the flexible bag (60). The bag includes two oppositely positioned ends, one of which includes a microporous screen (66) and is situated to lie partially below a minimum level attained by blood in the reservoir (10). The second bag end is substantially open, and includes a porous element (120) partially coated with an antifoaming agent. The coated portion of the element is positioned above a maximum level attained by the blood in the hard shell. The potential of excessive mixing between the blood and air is reduced by controlling the expansion of the bag during blood flow.

Abstract: Fine (56) and coarse (58) resolvers are used to detect the length of cable (40) withdrawn from a spool (42) to provide an indication of the position of a neutron flux detector at the end of the cable. The position indicated by the resolvers (56,58) when the neutron flux detector passes a withdraw limit switch is stored in nonvolatile memory as an offset when the cable is first installed in a flux mapping system. Thereafter, the position indicated by the resolvers, each time the neutron flux detector passes the withdraw limit switch, is compared to the offset. If the difference between the two is significant, a warning is generated, but operation of the flux mapping system continues. During movement of the flux detector, the change in position between two readings of the resolvers is divided by an amount of time measured by a programmable interval timer to determine average speed. A warning is generated if the average speed is outside an expected range. The expected range may vary depending upon the position of the detector. The position indicated by the resolvers when the flux detector indicates a reduction in neutron flux due to the presence of grid straps is compared with predetermined grid strap positions to determine an accurate top of thimble limit.
