Abstract: DRY FILM PHOTORESIST FOR FORMING A CONFORMABLE         MASK AND METHOD OF APPLICATION TO A PRINTED CIRCUIT BOARD OR THE LIKE            ABSTRACT OF THE DISCLOSURE      A dry film for forming a solder mask includes a cover sheet, a photoimageable composition layer which is curable to form a solder mask and a top coat interposed between the cover sheet and the photoimageable composition layer which is selectively adherent to the photoimageable composition layer. The dry film is applied to a surface of a printed circuit board with a minor portion of the area of the photoimageable composition layer tacked to the printed circuit board.  The cover sheet is peeled away.  With heat and vacuum, the photoimageable composition layer is laminated to the irregular surface of the printed circuit board, conforming the photoimageable composition layer to the contours thereof and leaving the top coat as a protective covering over the photoimageable composition layer. The photoimageable composition layer is exposed to patterned actinic radiation, developed and cured to form a hard, permanent solder mask.

Title: Method of simultaneously entering data into overlapped windows
Inventor: BARKER BARBARA A
IPC: G06F3/048
Filed: 1989-03-30
Granted: 1992-11-10
Abstract: ABSTRACT OF THE DISCLOSURE           A method is disclosed for simultaneously entering data  into  a  plurality  of  active  computer  application programs which are displayed on a computer  system in a plurality of windows.  At least a portion of each of the plurality of windows are overlapped such that each window shares  a  common  overlapping  area.   A  display  attribute associated with each window is then utilized to determine whether  or not  that  window  will  "share"  the  common overlapping area with other windows.  Thereafter, data input into the common overlapping area is shared by the computer application programs represented in those windows.   In a preferred embodiment of the present invention, separation of two  overlapped  windows  after  data  entry  into  a  common overlapped area will result in the presence of that data in both windows without the necessity of rekeying or copying that data.

Title: Apparatus for flushing of hydraulic pipe systems or the like
Inventor: SUNDHOLM GORAN
IPC: F15B21/04
Filed: 1989-04-26
Granted: 1993-01-26
Abstract: Abstract The invention relates to an apparatus for flushing hydraulic pipe systems of so called normal size.  Between the pipe system and a hydraulic aggregate a dual cylinder is connected, having a common piston shaft such that when the hydraulic aggregate pumps pressure fluid into one of the chamber parts containing the piston shaft, the other corresponding chamber part and one of the two outer chamber parts feeds in flushing fluid to the inlet of the pipe system whilst the other of the outer chamber parts receives fluid from the outlet of the pipe system through a filter and the remainder of the outlet flow is directed back to the hydraulic aggregate.  In this manner, a flushing volume considerably exceeding the volume capacity of the hydraulic aggregate is attained.

Abstract: ABSTRACT          A composite material propeller blade comprises a shell having an aerodynamic profile made up by at least one layer of fiber fabrics with high mechanical resistance which has been rigidified by a polymerized synthetic resin. A filling body is made of a cellular or foam synthetic material in the shell, and the spar whose lon-gitudinal axis is substantially parallel to that of the blade is constituted by a single elongated leaf of rovings of fibers with high mechanical resistance agglomerated by a polymerized synthetic resine such that the major part of the leaf is fixed in the shell and of which an end part of the leaf emerges from the shell and forms a twistable and flexible root part for which the spar is adapted to be connected to a hub. A metal leading edge cover is in-tegrated in the shell. The preformed filling body com-prises a cut-out which extends over the whole length of the body and opens in the face of the body turned towards the upper surface part of the shell and the section thereof corresponds substantially to that of the spar in the part which is fixed to the shell so that the spar is disposed in the housing defined by the cut-out in the filling body and the upper surface part opposite the shell.

Abstract: A method of producing an optical multi-fibre cable element provided with a secondary sheathing by extruding (1) a loose secondary sheathing (10) around a fibre bundle (9) and providing the fibres with a desired extra length with respect to the secondary sheathing. To avoid variation in fibre length in the production of cable elements the secondary sheathing (10) together with its the fibre bundle (9) is twisted (12) around its axis after the extrusion step (1) at least to such an extent that the longitudinal sliding of the fibres with respect to each other is prevented in the twisted fibre bundle and that the stretching of the fibres in the fibre bundle at the step of providing the extra length (3; 18) is kept within the elastic range of the fibres. In an apparatus suitable for realizing the method, twisting means (7) are provided after the extruder and before the device providing the extra length, which twisting means twist the secondary sheathing and the fibre bundle in such way that the fibres are locked together.

Abstract: A castable high-energy explosive composition comprising trinitrotoluene (TNT) and crystalline explosives of the RDX or HMX type as well as aluminium powder, and, optionally, flegmatising agents and stabilisers consisting of wax, lecithin and nitrocellulose (NC), is prepared by dispersing crystals of RDX or HMX in water with wax, under heavy stirring and at a temperature above the melting point of the wax, then adding aluminium powder, treated in order to tolerate water, to the dispersion, and then, optionally, cooling in order to separate the explosive as granules. A further step comprises melting and dispersing TNT in hot water under heavy stirring, optionally under the addition of wetted NC and lecithin, then reducing the temperature to below 80°C, and separating the solidifying, dispersed explosive droplets in the form of granules.The final step comprises mixing the products from the former steps in specific ratios so as to provide the final explosive compositions known by the name "Hexotonal" or "Octonal", respectively. Alternatively, the mixtures of granules from the first two steps are melted together and cast on a drum, ribbon or plate, or the first two steps are combined in the same reactor before any part of the dispersed phases has solidified.
