Title: Optical fibre testing
Inventor: ICHIKAWA AKIO
IPC: G01M11/00
Filed: 1991-09-26
Abstract: Apparatus for locating a position of a fault in an optical fiber, and/or measuring transmission losses in the optical fiber, inputs a pulsed light beam into the optical fiber and detects a reflected light using heterodyne detection. Coherent light emitted by source 1 is separated into signal 11 and reference 12 light beams. The signal light beam is pulsed at 3 while the reference light beam is intermittently frequency shifted by a predetermined amount by frequency shifter 5 and timing generator 6. The pulsed light beam is input to the optical fiber under test through coupler 7 which receives a return light beam from the fiber which is combined with the reference light beam. An optical heterodyning detector 9A detects the frequency difference between the return light and the frequency-shifted reference light beam thereby to produce a difference signal which is processed for evaluation of the optical fiber. Alternatively, the reference and signal lights beams may both be frequency shifted (fig 3). <IMAGE>
Patent GB-2260917-A (GB)
Title: Automatic vent system
Inventor: STAMP JEFFREY
IPC: G21C9/004
Filed: 1991-11-01
Abstract: An automatic vent system can be used, for example, in a contaminant 28 of a nuclear reactor so that when pressure in the contaminant rises as a result of an accident, gas and contaminant (particles) pass into inertial separators 17 in a chamber 18 into where contaminant is separated and exhausted within the contaminant from chamber 18 by a pump impeller 26, while clean gas passing from the separators into a duct 12 drives a turbine 24 to power the impeller 26. The system requires no external power source and can thus remain dormant until an emergency occurs and then provide high extraction of contaminant with minimum pressure drop with maximum extraction of contaminants. Coalescer/mist eliminators 30, 31 may be located upstream and/or downstream of separators 17. In an alternative arrangement, the pump impeller (or other pump) can be driven from an external power source. <IMAGE>

IPC: C25D11/12
Abstract: 914,834. Anodizing aluminium. NYOMDAIPARI KISERLETI UZEM ES LABORATORIUM. Jan. 4, 1961, No. 397/61. Class 41. Aluminium or aluminium alloy offset printing- plates are prepared by anodizing the aluminium plate first in HNO 3  and then in H 2 SO 4 . Preferably alternating current is used at about 3.5 A.S.Dcm. for the first stage and 0.9 to 2.5 A.S.Dcm. for the second. In examples, plates of Al, Al/Mg, or Al/Si alloy are cleaned with alkali and acid, and rubbed with CaCO 3 , and then suspended in dilute HNO 3  and electrolyzed for 20 minutes. After washing the further electrolytic treatment in dilute H 2 SO 4  is effected. The plates are then washed and dried in a current of warm air. It is stated that the relatively large pores in the oxide surface so made exceed 0.1 Á and readily absorb the resins and gum arabic used in the printing ink.
Patent GB-2263939-A (GB)
Title: Turbocharger system
Inventor: WALKER JAKE
IPC: F02B37/18
Filed: 1992-02-05
Abstract: The actuator comprises a piston 50 which divides the actuator body 40 into two chambers. An actuating rod 38 connects the wastegate (28, Fig. 1) to the piston and a spring 62 lightly biases the wastegate closed. A modulating unit 80 has valves 96, 98 which are mechanically or electrically linked together, 97, to oscillate continuously between their extreme positions to alternately supply pressure from the inlet duct via line 102 to each chamber in turn, the remaining chamber being exposed to atmospheric pressure via lines 92, 94. By varying the proportion of time during which the inlet pressure is supplied to a particular side of the piston the force acting against the piston in either direction can be controlled and hence the opening of the wastegate can be controlled. The valves 96, 98 are controlled by signals from an engine speed sensor and a throttle angle sensor. <IMAGE>
Patent GB-2256663-A (GB)
Title: Latching mechanisms.
Inventor: JOHNS RAY
IPC: E21B34/10
Filed: 1992-05-29
Abstract: Once a new oil well has been drilled and cased, a test string is set in place for the purpose of evaluating the production potential of the chosen formation. One way of controlling the operation of the various tools included in the test string is by changes in the pressure differential between the tubing 113 and the annular space 114 which surrounds it in the well, and an essential component of the test string to be controlled in this way is the sub-surface control valve 118, which may conveniently be a ball valve. However, a problem is experienced when employing a biased-closed valve: the annulus pressure needed to keep the valve open may have to be maintained for extended periods. The invention solves this by providing latch means whereby the valve actuating sleeve may be retained in the valve-open position even when the applied annulus pressure is removed, a first pulse of applied annulus pressure causing the valve to open and then, as the pressure is removed, become latched in the open state, and thereafter a second pulse of applied annulus pressure unlatching the valve and allowing it to close once the pulse has ended. <IMAGE>

The inner edge of lip 42 may be made with a wavy edge which may be of sinusoidal form or of a form having a plurality of adjoining V-shapes. <IMAGE>
Patent GB-2269205-A (GB)
Title: Security of paper items
Inventor: TERRY PETER ALFRED
IPC: G07D11/00
Filed: 1992-07-08
Abstract: A security system is received within the housing of an ATM having containers (2) in which bank notes are stored prior to being dispensed to the public. The system comprises a canister (4) containing a dyestuff under pressure and a hydraulic circuit (6) for discharging the dyestuff into the containers (2). A control circuit (22) is arranged to produce a control signal to actuate a valve (8) of the canister (4) upon the sensing of the existence of an alarm condition by sensors (26, 28). The first sensor (26) is arranged to detect physical movement of the ATM, for example, if the ATM is ripped out of a supporting structure. The second sensor (28) is a vibration detector and arranged to detect attempts to drill or break into the housing of the ATM in situ. The security system may not prevent an ATM from being pulled out of a wall and transported away. However, this action will cause the bank notes to be dyed and therefore renders them unusable. The existence of the security system should therefore act as a deterrent. <IMAGE>

Title: Method and apparatus for marking information on the outer surface of a polymer covered cable or wire.
Inventor: WILLIAMS STEWART WYNN
IPC: B41F17/10
Filed: 1992-08-20
Abstract: A method and apparatus for marking information on the outer surface 1 of a polymer covered cable or wire 2 includes feeding the cable 2 past an ultra-violet laser marking station 3, 4 to produce a desired shape marking therein, feeding the laser marked cable through an ink printing station 7 and ink printing the desired shape marking on top of the laser marking 5. The UV laser irradiation not only produces a laser marking but makes the marked region more hydrophylic and thus improves ink adhesion thereto at the ink printing stage. If part of the high contrast ink printed marking is erased or becomes removed during use the lower contrast, more resistant to erasure laser marking 5 underneath will be uncovered and become visible thus retaining the marking information. <IMAGE>

Title: Twin throttle cruise control
Inventor: TASHIRO KENJI
IPC: B60K28/16
Filed: 1993-03-08
Abstract: In an ic engine having two throttle valves 11, 12 in the air intake passage 10, the operation of the first valve 12 is regulated so that a target speed is achieved when cruise control is selected. The second throttle valve 11 controls the power of the engine and operates according to a selected one of a number of stored operating modes which define a target angle for the second throttle valve 11 as a function of the angle of the first. The modes set the relationship between the engine torque and the angle of the first throttle valve (figure 3) and can be dependent on the friction condition of the road such that the maximum permitted torque is lower when wheelslip is likely. The target angle SA of the first throttle valve 12 may be set according to the selected operating mode (figure 8). <IMAGE>
