Patent GB-2171574-A (GB)
Title: Image contraction and dilation
Inventor: JONES BRIAN ROBERT
IPC: H04N1/40
Filed: 1986-02-20
Abstract: For each pel signal comprising only 1 bit of information in and image a 16 bit word is available. The signals are processed so that the 1 bit of information from each of a surrounding patch of pels is inserted into the 16 bit word. The information on the surrounding patch provided by the pattern of bits in each signal is used to further process the signals to force the original bit to one or zero dependent on that pattern and also on the type of effect in the image required. The processing can be used to produce contraction or dilation or a combination of the two in the white parts of an image. To contact a white image, any white pel with a black neighbour is forced to back, whilst to dilate an image, any black pel with a white neighbour is forced to white. If the process of contractions is applied to figure 1 white pel 3, which may be due to noise, disappears and black area 2 grows resulting in white area 2 becoming two separate areas. The technique is useful in the scanning microscopy of metallic specimens for non- metallic inclusions. <IMAGE>

Title: Dual flapper valve assembly
Inventor: CLARY SAMMY RAY
IPC: E21B34/06
Filed: 1989-06-16
Abstract: A dual flapper valve assembly (10A, 10B) permits a well logging operation to be carried out after a gravel pack has been deposited without losing a large amount of completion fluid into the formation. The dual flapper valves (10A, 10B) can be closed and have frangible closure plates 70A and 70B which can be fracture independently of each other and selectively to accommodate a gravel pack operation, a well logging operation and a completion fluid recovery operation. The closure plate (70B) of the lower flapper valve (10B) is propped open by a wash pipe (46T) during the gravel pack operation. The lower closure plate (70B) is fractured to accommodate a well logging operation, while the closure plate (70A) of the upper flapper valve (10A) is held open by a prop sleeve (100). Upon completion of the well logging operation, the prop sleeve (100) is retracted out of engagement with the closure plate (70A) of the upper flapper valve (10A), thereby permitting the upper flapper valve to close. The heavy completion fluid remaining in the upper well bore annulus (42) is thereby conserved and can be recovered to the surface, while the gravel pack and the formation (48) are protected from the pressure of the heavy completion fluid. After recovery of the completion fluid, the closure plate (70A) of the upper flapper valve (10A) is fractured to accommodate production operations. <IMAGE>

Abstract: For coloring at least part of the image on a copying paper sheet which bears a black toner image formed by an electrostatic copier, an organic solvent is applied to at least the toner portions 3 on the sheet 2, and then a color transfer foil consisting of a transparent synthetic polymer sheet 5, preferably a separating or release layer 6 and a colored foil 8, is cut to a desired size and overlapped and pressed with the wetted toner image; the image is gelated to make it adhesive by the solvent which is then allowed to dry. The foil 4 is then released, and portions of the foil are torn from the remainder of the foil in contact with the non-toner portions so that the foil remains adhered to the sheet only at the original toner portions. The prefered solvent is petroleum benzine, which may be mixed with other solvents, e.g. toluene or a halogenated hydrocarbon. <IMAGE>
