Abstract: A method of manufacture of a sound absorption foam core board is described as well as vehicle trim panels (60) made from such board. A foam board (Fig. 2) having a cell structure including a structure with large cells in a center portion (30) is initially formed. This board is skived into two separate panels (40,42), each having one surface with relatively large cell structure and wherein said cells have been opened by the skiving process (34). This surface acts to promote enhanced sound absorption from the foam core board. This board may be laminated with appropriate decorative material and molded to make contoured resilient vehicle trim panels (60).

Abstract: A process for post-treating pre-expanded polyolefin resin particles which comprises charging in a vessel pre-expanded polyolefin resin particles which are pre-expanded by using a inflammable blowing agent, supplying an inert gas into the vessel, and then discharging the inert gas with the inflammable blowing agent gas extracted from the pre-expanded polyolefin resin particles, from the vessel. According to the process of the invention, the inflammable blowing agent can be extracted efficiently, safely and in a short time from the pre-expanded polyolefin resin particles which are pre-expanded by using the inflammable blowing agent. Consequently, the spontaneous cambustion of the particles can be completely avoided even if sparks are generated on the surface of the pre-expanded particles, therefore, it becomes easy to handle the pre-expanded polyolefin resin particles because the particles can be dried and transported by a pneumatic conveyer.

Abstract: An attitude control system for a three-axis controlled spacecraft (1) in which the location of thrusters causes significant cross-coupling torques. A thruster command conditioning electronics module (TCCEM) (3) is positioned between the conventional roll, pitch, and yaw loop controllers (41-43) and the thrusters (61-63). The TCCEM (3) converts spacecraft-axis-based torque requirement signals (TDX, TDY, TDZ) emanating from the loop controllers (41-43) into scalar quantities (UL, UM, UN) that are input to thruster modulators (51-53) that turn on one or more thrusters of the thruster pairs (L,M,N). The TCCEM (3) causes the spacecraft (1) attitude to be adjusted as commanded by the torque requirement signals (TDX, TDY, TDZ) despite the presence of the cross-coupling. Two embodiments are illustrated: a working embodiment in which cross-coupling torques are produced about two axes (Y,Z), and a more general embodiment in which cross-coupling torques are present about all three axes (X,Y,Z).

Abstract: The present invention provides novel acrylic block copolymer pressure-sensitive adhesive compositions and a method of making the same by use of an iniferter as a means of promoting, controlling and terminating polymerization. The method involves mixing an iniferter with a first polymer charge of acrylic monomer polymerizable to an acrylic block, exposing the mixture to an energy source to cause the iniferter to dissociate to form free radicals, permitting the first monomer charge to polymerize, terminating the exposure, adding a second monomer charge polymerizable to a reinforcing polymer block and again exposing the mixture to produce free radicals, permitting the second monomer charge to polymerize, and terminating the second exposure. The resultant reinforced acrylic block copolymer and tackifier, if needed, provides a pressure-sensitive adhesive composition which can be coated on a suitable backing sheet to provide an adhesive coated sheet material.

Abstract: The invention relates to a braking device (200) for a motorised hand saw, in particular a chain saw (10) with a drive casing (14), in which a hand protection lever (16) pivotable by the user about a pivot (17) fixed to the housing is arranged in the vicinity of a guiding handle (15) extending transversely to the sawing tool in order to prevent a dangerous operating condition, the said lever bringing a band brake (18) subject to the force of a spring element (55) to rest against a brake drum (13) revolving with the sawing tool by releasing a latch-type locking mechanism (60a) during its pivoting movement, it being possible to use the hand protection lever (16) to actuate an actuating cam (64) by means of which a swivelling lever (60) mounted pivotably about a swivelling axis (61) can be unlocked by a pivoting movement of the hand protection lever (16) away from the guiding handle (15), thereby bringing the braking device (200) into action, and it being possible to clamp and lock the swivelling lever (60) by an opposite swivelling movement of the hand protection lever (16) which releases the brake band (18). In order to provide a braking device of this kind with a release and clamping system of simpler construction, the saving in components (e.g. spring element, lever, pivot, securing element) which can thereby be achieved being intended to lead to a reduction in weight, overall size and costs, it is proposed that the spring element (55) additionally serves for fixing the hand protection lever (16) in its rest position. <IMAGE>
