Abstract: The optical presence detector sender and receiver lobes overlap each other within an area. The level of the signal from the receiver is used to ascertain whether an object is detected or not. The receiver sensitivity is suitable for detecting a dark object within the whole detection area. The sender and receiver lobes emerge from points at a specific distance from each other. The area within which the object is detected coincides with the area where the sender lobe coincides with the receiver lobe, and is defined in an angle direction, relatively to a plane which includes the receiver lobe centre line and the sender. The lobes are limited to a level taken up by the receiver output signal to at most a twentieth part when the object is moved in a direction away from the receiver.

Abstract: A method for producing bleached wood pulp in which wood chips are digested in polysulfide liquor to produce brown stock pulp. The brown stock pulp is washed to produce washed brown stock wood pulp and weak black liquor and the washed wood pulp is then delignified in an oxygen delignification stage to produce oxygen delignified wood pulp. The delignified wood pulp is then ozone bleached in an ozone bleaching stage in which a waste stream principally containing ozone, carbon dioxide and oxygen is produced. The ozone-bleached pulp is introduced into an extractive oxidation stage which can include peroxide to further bleach the pulp and the product of the extractive oxidation stage is then either introduced into either a peroxide or chlorine dioxide bleaching stage. The waste stream is recovered and scrubbed with either white liquor, oxidized white liquor, or fully oxidized white liquor either in a separate scrubber or during oxidation reactions occurring in either polysulfide, white liquor or complete white liquor production stages. The scrubbing with white liquor or oxidized white liquor removes ozone and carbon dioxide so that the scrubbed stream can be utilized in the oxygen delignification stage. This eliminates the need for ozone destruct units. Moreover, the polysulfide liquor is utilized in the digestion of the wood pulp and the thiosulfate liquor is used in the oxygen delignification of the washed wood pulp. The fully oxidized white liquor can be utilized within the extractive oxidation stage and optionally can be used in a peroxide bleaching stage if present. The oxygen removed from the scrubbed stream can be balanced with oxygen demand of the foregoing stages.

Abstract: Method for flocking of surfaces with fiber particles held to the surface by a solid layer, where the fibre particles are charged with static electricity during the application of the particles to the layer in a state of the same when the particles can be bound. The layer is obtained by giving pulver particles of a polymer a static charge, and sprayed onto the object which is to be flocked. Subsequently the particles are applied by spraying, after having been given a static charge of different potential or polarity in respect to that which the pulver particles have been given. Finally the object is heated, so that the polymer melts and forms said layer, and solidifies after cooling, thereby keeping the fiber particles in place.

Abstract: The device includes two or more communications parts (106A,114A) which form part of a CAN-system, respectively between the CAN-system and a control unit, and which are communicable via one or more wireless connections. When a transmission is made from a first transmission part (114A) to a second communication part (106A), the parts operate with a signal protocol which takes no account of arbitration and/or confirmation functions found in the CAN-system. A particular receiving communication part executes or assists in conversion of the signal protocol to the signal protocol of the CAN-system. The communication parts can be coupled to the CAN-system, which in the non-connected-up or non-activated state of the communication parts form a unitary system (201A). In the connected-up or activated state of the communication parts two CAN-systems are formed (202A,205A) which operate separately relative to each other, with a protocol which is distinct from the CAN-protocol, e.g. ethernet, wave-raider, e.t.c.

Abstract: A slot-widening key for use with insert holders of the kind that includes a blade shaped body having a slot intended to receive an insert. One surface of the slot is defined by an elastically flexible clamping arm for clamping the insert. The key has a shaft with two projections for engaging laterally opening seats in the body and the clamping arm, respectively. One of these two projections is provided on a pivoting link that is pivotably connected with the shaft via a hinge pin. The sum of a first distance between the hinge pin and one of projections, plus a second distance between the hinge pin and the other projection, is larger than the at-rest distance between the seats of the insert holder. Pivoting of the shaft beyond an unstable position of equilibrium thus makes the clamping arm deflect by a predetermined value for widening the slot. The key is self-supporting in the slot-widening position and does not require that the manual force be continuously applied.
