Title: Building services water supply programmable isolation and malfunction indication system
Inventor: LONERGAN LAWRENCE PATRICK
IPC: F16K37/00
Filed: 1989-12-14
Abstract: The system comprises a unit which is fitted into water service supplies. A programmable controller allows the system to be armed to protect water services during periods of no-demand and disarmed to provide normal service. Manual override allows permanent armed or disarmed settings. Should the service malfunction during armed periods the system will ignore pro-set programmes staying armed until manual re-set. Figure 2 illustrates the armed system. A system operated isolation valve 1 stems the main flow. Pressure is maintained at points 3 and 4 via the secondary chamber 5. Service malfunction will cause pressure loss at 4; thus service pressure at 3 pushes actuator 6 to seating 7 isolating the service. This action makes electrical contacts 9, signalling a warning at the controller. System reset opens valve 1, restoring constant pressure throughout. Spring 8, or similar means, returns actuator 6, breaking contacts 9 and cancelling the warning signal. <IMAGE>

Title: Diving snorkel
Inventor: LIN HSIN-LAN
IPC: B63C11/20
Filed: 1990-07-21
Abstract: A diving snorkel (10) has an inner tube (50) inside a co-axial outer tube (20) providing inhaling (21) and exhaling (55) passages. A tubular sleeve (40) inside the top of the outer tube (20), has plural intake valve ports (42) in a radial top flange (41). An annular flat one-way check valve disc (43) controls the intake valve ports (42). A flat one-way check valve disc (53) controls exhaust. An annular housing body (30) at the top of the snorkel has plural intake holes (33) and exhaust holes (34) adjacent the inhaling and exhaust valve discs. A flat annular water check valve disc is carried by a tubular float (61) below the intake valve ports (42) and the intake holes (31), and will close only when water raises the float (61). A diver using the snorkel for breathing avoids inhaling previously exhaled waste carbon dioxide, and water is prevented from entering the snorkel. <IMAGE>

Patent GB-2253701-A (GB)
Title: Air leakage monitoring methods
Inventor: RAY WILLIAM ADAMS
IPC: G01F1/74
Filed: 1991-02-15
Abstract: A method and apparatus for monitoring the amount of air mixed with steam flowing along a duct, for example in a condensing steam-driven electricity generating plant, down-stream of a turbine. The absolute pressure, velocity and temperature of the steam/air mixture flowing along the duct are measured and then the measured values are processed in real time to derive both the steam partial pressure at the measured temperature, and the total mass flow along the duct. The derived mass flow is further processed with the derived steam partial pressure to obtain an output indicative of the air mass flow rate along the duct and this may be expressed as a percentage of the total mass flow. The output may be averaged and displayed to give a real time indication of the amount of air, to monitor air leakage into the condenser. A pitot tube assembly with multiple upstream-facing pressure tappings and incorporating a temperature transducer is described. <IMAGE>

Title: Improvements relating to ice penetrating devices
Inventor: COLLISTER CHRISTOPHER JOHN
IPC: E21B7/14
Filed: 1991-05-09
Abstract: An ice penetrating device, e.g. for use in radio or acoustic communication, comprises a thermo-chemical boiler for converting water into steam under pressure, and a probe 23 through which the pressurized steam is released in the region in which ice is to be penetrated. The probe may comprise a plurality of lengths telescopically received within one another, which are extended by the pressure of the steam and joined to allow leakage of steam therethrough. Upon initiation, a gas generator 19 is heated and a thermo-chemical furnace 15 is ignited; eventually wax bungs 13 melt to allow pressurised water and anti-freeze mixture 14 to enter a space between the furnace 15 and canister walls 11, where it is heated and vapourized. Emergent steam is directed axially and radially from a nozzle 35. Deployment of the probe unwinds a communication wire 24.

IPC: G01N27/90
Filed: 1992-07-08
Abstract: The apparatus for inspecting large cylinders such as generator retaining rings, has sensors for simultaneously detecting flaws in inner and outer surfaces of the cylinder and in the body of the cylinder. The sensors are mounted on a scanner 22 which moves around the circumference of the cylinder and on which the sensors can move axially of the cylinder. The sensor outputs and sensor location signals are transmitted to a remote location 13, 16 and the apparatus is remotely controlled by computer 19. The sensors are eddy current and ultrasonic. The scanner has drive sprockets which engage chains placed round the cylinder and carries a platform which moves axially and on which the sensors are mounted. Position encoders act to accurately locate the sensors on the retaining ring. The retaining ring can be inspected while the rotor remains in place in the generator stator, or with the rotor removed. <IMAGE>

Patent GB-2264571-A (GB)
Title: Group controlled elevator system
Inventor: TOBITA TOSHIMITSU
IPC: B66B1/20
Filed: 1993-02-25
Abstract: A group controlled elevator system detects the concentration of multiple elevators (111, 112, 113, 114). If it exceeds a certain level, one of the elevators is restricted so as not to respond to hall calls, and a cage call destined elevator so that it is forced to separate. Overall waiting times are thereby reduced. The degree of concentration can be predicted on the basis of current cage calls and assigned hall calls, and the dispersion command issued when the predicted concentration exceeds the predetermined level. Also, the dispersion command can be suppressed if the cages will separate naturally. The arrangement is suitable for small numbers of cages and may (Fig 14) be used to coordinate just two lifts which do not have a supervisory group controller. <IMAGE>

Title: Selecting motion vectors in video signal processing; global motion vectors.
Inventor: DORRICOTT MARTIN REX
IPC: G06T7/20
Filed: 1993-04-08
Abstract: An image is divided into blocks and local motion vectors are derived for each block indicating the possible motions of the block between frames. Global motion vectors are derived by selecting the most frequently occurring local vectors over the whole image (103, fig 13). Association means 104 determine that a given global motion vector is "associated" with a given block by comparing 181 it with the local motion vectors. A global motion vector is associated with a block if it lies within a predetermined threshold 185 of the local motion vectors for that block. Assignment of motion vectors in a block (105, fig 13) is then made on a pixel by pixel basis from: the local motion vectors for that block, the local motion vectors for neighbouring blocks, and those global vectors (if any) associated with that block. <IMAGE>

The diaphragm (20) is integral with the flexible wall (13) and is in the shape of a frusto-cone. The former simplifies the construction of the mount and the latter enables the area of the diaphragm (20) to be increased for a given mount diameter. <IMAGE>

Title: Controlling audio level in dependence on ambient noise
Inventor: TRIM RICHARD MORRIS
IPC: H03G3/32
Filed: 1994-05-04
Abstract: An adaptive audio system, such as may be used for public address, is provided with an electrical control of its output by means of a circuit whose signal source is a microphone which senses the level of ambient acoustic noise in its locality and which provides an electrical controlling voltage whose amplitude is a function of this level. By this means, the magnitude, or volume, of the system audio output is adapted to the ambient acoustic noise level as sensed by the microphone. The controlling circuit also includes provision for a pre-set threshold 6 and 7 which prevents the adaptive facility from coming into operation until a predetermined level of ambient acoustic noise is sensed by the microphone. This provision avoids continual changes in audio output level in response to operationally insignificant changes in sensed acoustic ambient noise. Time constants and biases may also be set and a display of signal level may be provided. Detection of passengers or rolling stock may also be used for control purposes. <IMAGE>
