Abstract: A gas-fired direct-contact water heater system 10 is described. It consists of a first housingll, 50, 80 having a packing 16, 51, 81 of heat exchange elements 17 and on which water is sprayed. A burner 18, 52, 83 is disposed on the side of the housing under the packing. A combustible gas feed pipe is connected to the burner 18, 52, 83 to provide a combustible gas to the burner. A water collection reservoir 20, 58, 86 is defined below the burner for collecting heated water. A further packing 31-59-91 having heat exchange elements is located in a further housing 30-60-90 and it is also sprayed water. Ambient air is admitted under this packing by a blower 32-63-101 whereby the air is humidified and heated and supplied to the burner for admixture with the gas whereby to obtain a higher combustion product dew point and a reduction in the NO x emission when burned. A further water collecting reservoir 35,62-93 is defined in the second housing 30-60-90 below the packing 31, 59, 91 for collecting water percolated through the further packing.      Heated water is converted through a first conduit 36, 69, 107 from the water collection reservoir 35, 62, 93 in the first housing. A further conduit 36, 76', 99 is also provided for converting water from the further housing. The flue gases from the first packing are also cooled in a third packing before being released to atmosphere.

Abstract: A method and apparatus for continuously monitoring fluid level in an oil well, by measuring changes in the weight of the oil well tubing which result from changes in the buoyancy of the tubing caused by the rise and fall of fluid level within the oil well.  In the apparatus of the invention, a transducer is either affixed to the downhole tubing of the oil well, or  alternatively, is affixed to the drive head support structure of a well having a progressive cavity well pump.  The transducer continuously senses changes in the weight of the tubing as the buoyancy of the tubing changes in proportion to the rise and fall of fluid level within the well.  The transducer is preferably connected to a control unit which, in turn, is connected to the pump motor and which functions to automatically control the pump motor as a function of fluid level within the well.

Abstract: An electronic load weigh device is used with a railcar truck control unit. A relay valve provides to a brake cylinder a pressure proportional to the pressure impinging upon its control port. A first feedback signal is indicative of the pressure at the control port. A second feedback signal is indicative of the load borne by the truck. A pressure switch opens when pressure within a trainline changes to a level indicative of an emergency. By controlling the opening and closing of application and release magnet valves, a controller controls the pressure impinging on the control port and thereby service braking of the wheels of the truck. The load weigh device includes (i) circuitry for electronically compensating for the load during braking and (ii) a mechanism for granting the circuitry exclusive control over the magnet valves. Should such emergency occur, the mechanism responds to such emergency by disconnecting the controller from the magnet valves. This gives the circuitry exclusive control over the magnet valves.      The circuitry compensates for the load borne by the truck during emergency braking by selectively opening and closing the magnet valves, according to predetermined criteria using the feedback signals, thereby controlling the magnitude of the pressure impinging upon the control port. Absent such emergency, the mechanism responds to such absence by connecting the controller to the magnet valves whereby such service braking on the truck is normally controlled, yet the circuitry is still enabled to compensate for the load during such service braking.

Abstract: A filled hollow structure (10), such as a fence post, which is constructed with a hollow member (14) filled with a core (12) to increase its strength.  One aspect of the structure is that the core material normal expands upon setting, so that, when hardening within the hollow member, the expansion is restrained by the hollow member and the core is formed into an integral structure with the hollow member. Further strength is added by constructing the hollow member of reinforced fiberglass with the fiberglass rovings oriented at an angle to the axis of the pipe and by using a hard coating (18) on the outside of the pipe.

When the supply voltage line (11) is connected to a supply voltage source (12), the first sensing unit (14) causes an immediate switching-on operation of the control circuit (18) if the voltage conditions on the supply voltage line (11) sensed by the first sensing unit (14) at said moment are acceptable. After a switching-on operation of the control switch (18) caused by the first sensing unit (14), the second sensin g unit (15), which is operatively connected to the control switch (18) via a delay unit (21), provides a delayed control of the state of the control switch (18) in dependence upon the voltage conditions on the supply voltage line (11) sensed by the second sensing unit (15).

Title: Call set-up process
Inventor: CLAPTON ALAN JAMES
IPC: H04W88/16
Filed: 1997-11-27
Granted: 2007-11-20
Abstract: The arrangement disclosed allows a user of a mobile telephone (11) to use intelligent network (IN) services spe-cific to his home network, regardless of whether the network (12, 13, 14) to which he is currently connected can support the service. When the user makes an outgoing call attempt (step 1) the as-sociated signalling is transmitted over a signalling channel. The mobile switch-ing centre (MSC) (13) recognises a cus-tomer identity (encoded electronically in the call set-up signals) and accesses the data relating to the user which is stored in a register (14). The data in the reg-ister (14) relating to the user (11) in-cludes a marking identifying him as an IN served customer, causing the MSC  (13) to halt the call process and send a signal (2), protocol, to the service con-trol point (SCP) (15) in the user's home network. The SCP (15) then activates the user's service profile and as part of that profile recognises the need to retrieve additional infor-mation from the user (11), e.g. a PIN (personal identity number) or some other information. Having identified the information needed, the SCP initiates a message (3) to the mobile station, for example requesting an authorisation code, which is passed back to the MS (11) by way of the switching centre MSC (13) and base station BSS (12), using a signalling protocol. The user, having received the message (3), responds such that the mobile station (11) sends a second signal (4) by way of the host network back to the SCP (15). The SCP (15) acts on the message received and returns a response (5) to the MSC (13), whereby the MSC (13) will then act on that information for example to set up a call, including a full speech channel if required (6). This system allows data to be transmitted directly between the SCP (15) and the user (11), the host network not requiring to be compatible with the signalling protocols except for the initial and final stages (1, 5).  Moreover, since signalling channels are used, traffic (speech) channels, which have a larger bandwidth, are not used unless and until the call set-up process is completed.
