Title: Dynamic method for the detection of discontinuities in a body
Inventor: COOKE-YARBROUGH EDMUND HARRY
IPC: G01N3/32
Filed: 1984-04-12
Abstract: A method of detecting stress sensitive discontinuities in a body, comprises subjecting the body to an alternating or changing stress, directing pulses of ultrasonic signals into the body, detecting ultrasonic signals returning from the body, storing the said signals and comparing the stored signals corresponding to returning signals originating at one level of the alternating stress with those originating at another level of the alternating stress thereby to eliminate those return signals which do not vary in accordance with the applied stress. To perform the comparison, digitized ultrasonic returns maybe multiplied 9 by 1 for stresses above average, and by -1 for stresses below average, then added 11 to signals already stored. Discontinuities, not sensitive to stress will tend to produce a zero resultant in memory 12 whilst those sensitive to stress will give a non-zero resultant. <IMAGE>

Patent GB-2209240-A (GB)
Title: A method of decontaminating large vessels
Inventor: WILLIAMS JOHN
IPC: G21F9/00
Filed: 1987-08-26
Abstract: A method of removing contamination from the surfaces of nuclear reactors, heat exchangers and pressure vessels which requires the use of only small volumes of liquid and no abrasives involves contacting the contaminated surface with a moisture laden gas and effecting condensation of the moisture in the gas on the surface by lowering the temperature of the surface to be cleaned before introducing the moisture laden gas. A reactive cleaning agent is concurrently or subsequently introduced and allowed to react with the contaminated surface to produce a water soluble reaction product which is washed away. To ensure the retention of a wetted surface for reactant contact and to avoid loss of reactant contact by evaporation or drainage at the surface a modification of the method provides for the production of the gelatinous layer on the surface to be cleaned.

Patent GB-876740-A (GB)
Abstract: 876,740. Photogrammetry. NATIONAL RESEARCH COUNCIL. Aug. 12, 1958 [Aug. 28, 1957], No. 25875/58. Class 97(1) A stereoscopic device 20 is used to view overlapping aerial photographs 16, 17 on carriers 14, 15 mounted for rotary adjustment on carriers 12, 13 movable by motors 23, 24, 25, 26 in perpendicular co-ordinate directions with respect to a carriage 11 movable in perpendicular co-ordinate directions by handwheels 21, 22 relatively to a base 10. The handwheels are operated to bring fresh parts of the photographs into position for observation. The motors 23-26 are energized from an electronic computer which has a control by which the carriers 12, 13 may be moved to produce relative movement of the photographs to remove parallax between the observed stereoscopic image of a feature in the photographs and a measuring mark in the stereopscope. The setting of this control is thus a measure of the height co-ordinate of the feature. The computer also has settings which take into account of differences between the two photographs, as to conditions of exposure, especially height of exposure and tilt of camera axis, and defects in the individual photographs due, for example, to lens distortion, atmospheric refraction, film shrinkage and curvature of the earth. All these corrections depend on the positions in the photographs of the points under observation and, to enable them to be calculated co-ordinate data are fed to the computer from potentiometers on the shafts of the handwheels 21, 22. The amounts of the corrections fed to the carriers 12 and 13 by the motors 23-26 are indicated by dials 27, 28, 29, 30. The rotational adjustments of the carriers 14 and 15 are effected by graduated handwheels 31, 32. The procedure for initial setting of these adjustments and of the various computer adjustments is described in detail in the Specification together with the detailed schematic arrangement of the computer and the mathematical analysis on which it is based. The computer described is of the analogue type, but a digital computer may be used. As a result of the corrections supplied from the computer, the handwheels 21, 22 rotate in terms of corrected co-ordinate data and their rotations are transmitted mechanically to a plotting table. The photographs may be scanned electronically instead of being viewed by eye. Specification 764,449 is referred to.

Title: Device for controlling the movement of a door
Inventor: EVANS DAVID HOWARD
IPC: E05F3/22
Filed: 1986-11-17
Abstract: The device, which is for controlling the movement of a door (11), particularly the closing movement, comprises a linkage mechanism (45-47) connected between the frame (10) and a door closer (15a) mounted on a backplate (13), and retaining means (38) on the backplate for normally preventing return movement of part (47) of the linkage mechanism once the door has been opened, the part (47) being a catch plate integral with a spindle (16) of the door closer which is thus biassed to rotate in the door closing direction. If the catch plate (47) and a main arm (45) of the linkage mechanism are connected together, by bolt (49), the door is held open once it is moved to an open position. If the catch plate (47) is free of the main arm (45) the door is free-swinging once in the open position, while the catch plate (47) is retained by means (38). In the free-swinging arrangement, the bolt is secured in plate slot 48 to be abutted by link (45). The re-positioning of the bolt is thus used to convert from a free-swinging door to a held-open door. In the event of a fire means (38) automatically releases plate (47) to be rotated by the closer 15 to close the door regardless of whether it is in a free-swinging or held-open state. Manual closure is also possible with a door in the held open state by overcoming the hold-open force.   <IMAGE>
