Title: Leak detector and locator utilizing adaptive threshold and analog comparison
Inventor: BAILEY DOUGLAS SLOAN
IPC: G01R31/50
Filed: 1993-07-15
Abstract: A leak detector and locator utilizes a permeable coaxial electrical cable near to fluid carrying pipes or tanks or in other areas where leaks may occur. Pulses are applied to the cable and the reflected waveform is analyzed to detect changes in the characteristic impedance of the cable caused by a leaking fluid penetrating the insulation of the cable. During a calibration process, the waveform reflected by the cable is analyzed and upper and a lower reference thresholds are defined about the waveform for various points along the waveform. In the detection mode, an analog comparator compares subsequent reflected waveforms received from the cable with the upper and lower reference thresholds obtained during the calibration process. A break is indicated if the upper threshold is exceeded a predetermined number of times and a leak is indicated if the lower threshold is exceeded a predetermined number of times. Different widths of pulses may be employed to compensate for the increasing attenuation along long cables. <IMAGE>

Title: A leak detector for an injection moulding machine
Inventor: KENNEDY GERARD PATRICK
IPC: G01M3/04
Filed: 1994-09-06
Abstract: A leak detector for a plastics injection moulding machine comprises a small diameter conduit (20) located adjacent to a potential leak site on or associated with the machine, through which a regulated supply of air is emitted. When the conduit outlet (26) is blocked with leaked molten plastics, a sensor (45) in the conduit instantly detects a change in air flow or back pressure and triggers an alarm (65), and optionally cuts off the machine automatically to avoid damage to machine components and with the object of reducing machine down time. Changes in incoming primary air supply pressure may be detected to provide a fail-safe system. Alternatively, air pressure in the conduit (20) may be below zero, i.e. a vacuum, so that air is sucked into the conduit at its outlet (26). Several potential leak sites may be monitored simultaneously from a single sensor arrangement. <IMAGE>

Title: Production of smoked fish
Inventor: BROWNE JAMES
IPC: A23B4/052
Filed: 1995-10-06
Abstract: Smoked fish which is fresh and moist in taste and has a relatively long shelf life is produced by receiving chilled raw fish at a temperature in the range of -1{C to +4{C and processed into fillets. Smoking is carried out in a chamber with three stages which lead directly into each other. The three stages are drying, smoking and purging, all of which are carried out at 22-26{C and a relatively humidity of 55-75%. Only 80-100 minutes is required for drying and 6-7 hours is required for smoking. An 80% beech/20% oak sawdust combination is used for smoke generation and the temperature of smoke entering the chamber is maintained below 28{C, this limit activating an alarm. Smoked fillets are immediately transferred to a chill area below 0{C and are left for a minimum of four hours. Post-smoking processing takes place at temperature of 12-16{C within a processing area. Salt may be applied to the fish before smoking.

Abstract: A flap valve 35,45 for use in a vapour recovery system, of the kind used to vent vapour from a tanker whilst it is being loaded with a liquid (for example petrol), comprises an outlet and an inlet, a flap member 352,452 attached to a body 31,41 via a hinge 351,451 and sealing means 33,43 mounted in the body, onto which said flap member sits to provide a seal. The vapour recovery system has a pipe coupling between the truck valve 3 on the vent outlet (2, figure 1) of the tanker (1, figure 1) and the terminal valve 4 on the loading terminal. When the truck valve 3 is connected to the terminal valve 4, a protruding member 46 on the terminal valve 4 engages a roller 356 on the truck valve 3 which is connected to the flap member 352 via arms 353,355, and thus opens the valve 35. Likewise the outer surface 323 of the truck valve 3 engages the sensing pin 455 on the terminal valve 4 which is connected to the flap member 452 via arm 453, and thus opens the valve 45. The vapour recovery system is also preferably provided with a non-return valve (5, figures 1,6) so that the recovered vapours cannot return to the tanker.

Patent GB-2329227-A (GB)
Title: Temperature compensating clutch control method
Inventor: WAGNER ALFONS
IPC: F16D28/00
Filed: 1998-06-02
Abstract: An automatic clutch comprises an actuator 25, eg an electric motor, driving a crank drive 74 which operates a piston rod 72 of master piston 60. The master piston 60 contains a non-return valve 70 that allows hydraulic fluid to overflow from compensating chamber 62 into work chamber 58 of master cylinder 27. Movement of the master piston 60 is hydraulically transferred, via pipe 56, to slave piston 50 which extends to disengage the clutch and retracts, under an influence of a clutch spring, to engage the clutch. When engaging the clutch at low temperatures, eg -10‹C to -20‹C, the viscosity of the fluid prevents it moving quickly through pipe 56 so that under pressure occurs in the work chamber 58 which leads to an opening of the valve 70, thereby increasing the volume of fluid in chambers 52, 58. So that this increase in volume, eg pumping up, does not occur the speed of the electric motor 25 is altered, by an electronic controller, in dependence on the fluid temperature. For example, at low temperatures the speed of the motor 25 when engaging is slower than when disengaging, hence the retraction speed of the master piston 60 is matched to that of the fluid through pipe 56 so that no under pressure occurs and the valve 70 does not open. In another embodiment at low temperature a stroke of the piston 60 is controlled such that it passes snifting bore 64. The temperature maybe sensed, eg by temperature sensors in actuator 25, or it may be calculated. A method of checking the temperature sensors is also disclosed.
