Patent EP-0267718-A2 (EP)
Inventor: VERTZ RICHARD J
IPC: B23P15/04
Filed: 1987-11-02
Abstract: Air cooling of airfoils in a gas-turbine engine is effected through holes which terminate with a diffuser formation at the airfoil surface. The invention is directed to a two-step procedure whereby a laser beam drills the holes very quickly and cost-effectively and whereby an EDM step is relied upon only to form the diffuser shape. The EDM part of the procedure thus occupies but a fraction of the time previously required, and substantial over­all economy is realized by integrating these two steps, which are preferably performed in the order stated but which, if desired, may alternatively be performed by laser driling after EDM formation of the diffuser shape.

Abstract: A white toner comprising a fixing resin and dispersed therein, a titanium dioxide pigment of high purity containing at least 99% by weight of TiO₂, not more than 0.1% by weight of Al₂O₃ and not more than 0.05% by weight of SiO₂ as a white pigment. The white toner has markedly improved hygroscopicity as a result of using the white pigment in which the contents of metal oxides such as Al₂O₃ and SiO₂ are reduced to very small amounts. The toner can thus retain the stable and uniform amount of triboelectric charge, and permits effective circumvention of troubles such as the reduction of image density, background fog and image blurring.

Abstract: A directory DIR 112 stores identifying titles and pointers to areas 111 of a memory 15 storing respective messages. To protect the messages against unauthorized changes, a MAC (message authentication code) is calculated for them in known manner and stored in a register 116 in a secure unit 16. This involves processing the whole of each message every time the MAC is checked or, if a message has been changed, a fresh MAC has to be calculated. To avoid this, a separate MAC is calculated for each message and stored in the directory (in section 114), and a global MAC is calculated for the individual MAC's (treating them as if they were a message) and stored in a secure register 115. To check a stored message, the global MAC is recalculated (thus verifying the MAC of the message), and the MAC of the message is recalculated (thus verifying the message). If the message is changed, its new MAC and a new global MAC are calculated. 
     The system can be extended to a hierarchy of sub-global MAC's.

Abstract: A highly flexible, shielded electrical cable (10) having exceptional pliability and limpness is provided for connection to devices such as hand-held medical instruments to minimize the resistance to movement of such devices imposed by such cable. The normal stiffness of shielded cables caused by a braided wire shield is minimized by eliminating the frictional resistance to relative movement between the shield (20) and the dielectric covering (18) of the conductor assembly (12) inside the shield. This is accomplished by loosely braiding the shield (20) around the dielectric covering (18) so as to impose no transverseley inward force on the dielectric covering. Preferably, a clearance (22) is formed between the shield (20) and the dielectric covering (18) and the density of the braided shield (20) is maximized to render it self-supporting. An outer dielectric jacket (24) of the cable (10) likewise loosely encircles the braided shield (20) to eliminate frictional resistance to relative movement between the shield (20) and jacket (24).

Abstract: A method of batch producing capacitive pressure sensors is disclosed in which a sheet of two of a semiconductive material is provided with an insulating layer (4) on side thereof and a plurality of cavities (1) are formed in the semiconductive sheet by removing part of the insulating layer and part of the semiconductive sheet. Simultaneously with producing the cavities in the semiconductive sheet, at least one recess (12, 13) is provided, again by removing part of the insulating layer and part of the semiconductive sheet. The semiconductive sheet is then bonded to a non-conductive substrate (3) to form a composite sheet with the insulating layer (4) in contact with the substrate, the substrate being provided with a number of electrodes (5) corresponding to the number of cavities in the semiconductive sheet and arranged such that they are located within the cavities on bonding of the semiconductive sheet to the substrate, each electrode having an electrical feedthrough (6) extending therefrom and terminating at a point outside of the associated cavity but within an associated recess in the semiconductive sheet. The bonded composite sheet is patterned with a series of grid lines (8, 9) to delineate the plurality of pressure sensors and the semiconductive sheet is scored from the side opposite that provided with the insulating layer so as to break into each recess to reveal, at a stage in the method of production, the terminal end of each electrical feedthrough (6), and the bonded composite sheet is diced along the grid lines so as to separate the pressure sensors one from another.

Abstract: A container is provided in the form of a cup-like container body with a round mouth closed by a lid which becomes removably replaceable upon tearing away of a circumferentially extending tear strip which initially surround the mouth rim of the container body as a radially outer, integral part of the lid flange. As the lid is differential pressure-thermoformed, its radially outer region is formed into a generally inverted U-shaped structure which near the juncture of the base and radially outer leg of the inverted U, is provided, within the channel, with an inverted V-shaped notch of substantially diminished wall thickness to provide a line of weakness which preferably extends nearly fully around the circumference of the lid, but for at an angularly short tear-starting site. After the thermoforming step, and preferably in connection with trimming the lid from the surrounding scrap portion of the sheet in which it was formed, a mechanical crimper axially collapses and initially radially outwardly concave annular portion of the radially outer leg of the inverted U, intermediate the vertical extent of that leg, with an upwardly inwardly directed barb or hook which, cooperating with the rim of the cup provides the snap lock feature for securing the lid to the cup. After the initial lidding, it is this barb which prevents removal of the lid until the tear strip is torn away. Other cooperating structures preferably provided on the cup side wall and the radially inner   leg of the inverted U provide a surmountable-but-­sufficient snap lock which continues to be useful After the tear strip has been removed. By reference, the desired action of the tear strip in removal is enhanced by simple instructions provided on the container, and/or by provision of a crack-­initiating layer on the inner surface of the lid.

Abstract: The invention relates to a method and apparatus for treating non-ferrous metal drosses in order to recover the free metal contained therein. The dross is heated by a plasma torch (40) in a rotary furnace (10), preferably to a temperature above 800°C. The plasma heating and rotary motion make it possible to recover metal from the dross without employing the conventional salt bath. This means that the gases exiting the furnace can be treated more easily to remove pollutants and the solid residues can be discarded without risk of causing environmental pollution. By controlling the speed of rotation of the furnace (10), large dross lumps can be accommodated and so the conventional grinding and screening procedure of the dross can advantageously be eliminated.
