Patent EP-0267647-A2 (EP)
Inventor: JANSEN CORNELIS JOHANNES ADRIA
IPC: H04L9/06
Filed: 1987-11-05
Abstract: The invention relates to a method of enciphering information-containing digital data signals with the aid of enciphering keys and of deciphering a message thus enciphered, utilizing the same key. For usages in which high demands are made on the quality of enciphering the conventional method - the EX-OR adding together of clear text and key text on a bit basis - has shortcomings. The invention has for its object to provide a very reliable method with which furthermore the propagation of errors caused by any transmission errors is prevented. This is accomplished in that the (clear) text characters to be enciphered are processed using an enciphering key which is derived from a key text and that the nature of the processing operation performed on the clear text characters is determined by an instruction command which is also derived from the key text.

Abstract: A motion transmitting remote control assembly (10) including a conduit (12), and a motion transmitting core element (14) movably supported by the conduit. A terminal means (22) is attached to one end of the core element (14), and is adapted for attachment to a member to be controlled. The terminal means (22) is used to adjust the effective length of the core element (14) by manually locking the terminal means (22) into any one of various locking positions. The preferred embodiment includes three members. The first member (24) is attached to the core element (14) and defines an elongated opening (34). The second member (26) is attached to the control member and is slideably disposed within the opening (34) defined by the first member (24). The third member (28) interconnects the first and second members (24,26) and is movable between an unlocked position, allowing relative movement between the first and second members (24,26) along the axis of the core element (14), and a locked position for preventing such relative movement.

Abstract: A positive displacement pump for circulating fluids downhole comprises a rotor (70) which transmits torque from an upper drill string section to a tool (l9) attached to the lower end of the pump via a connecting means (52). Bow springs (90) prevent a stator portion (32) of the pump from rotating in the wellbore. Fluid is counterflowed up the interior of the drill string by the positive displacement pump through a check valve (l2) into a settling chamber (l4). Cuttings or other solids settle out of the fluid and the fluid is then pumped out through one or more discharge ports to the lowermost end of the drill string.

Abstract: The invention relates to a method for manufacturing a paper or cardboard product and to a product manufactured by the method. According to the invention, a cellulase enzyme is added to the product during manufacturing, said enzyme causing the product to decompose when exposed to moisture. The enzyme can be introduced into the product in connection with surface sizing, pigment coating or calendering, or it can be added in the form of a solution which is separately applied to the product in the dry end region of the paper or cardboard machine. Experiments have shown that a product manufactured as taught by the invention can be provided with a plastic coating without risk of destroying the enzyme. Cardboard produced by the method of the invention can be used in the manufacture of packages for liquids, of packing boxes or disposable containers, the cellulase enzyme serving to promote decomposition of the products after they have been brought as waste to dumping areas.

Abstract: A machine for winding two-pole stators includes a revolving table around which are located at least three working stations: a station to feed the machine with unwound stators from a conveyor placed alongside the machine and for returning the wound stators to the conveyor; a winding station where one or more winding needles with alternating translatory and angular motion wind the stator; and a terminating station with means to anchor the coil leads to the stator. The revolving table carries a plurality of circumferentially spaced stator housings, each stator housing having stator-containing means. The stator housings and table are equipped with mechanical, reciprocally meshing means, those on the table being located between the winding station and the load/unload station for rotating the stator housings about the horizontal axis tangentially to the table between a position in which the axis of the stator-containing means is vertical and a position in which that axis is horizontal. The stator housings further include a spring to keep the axis of the associated stator-containing means horizontal during movement of the housings from the load/unload station through the winding station to the terminating station.
