Abstract: ABSTRACT OF THE DISCLOSURE         A multilayer structure comprising (C) a substrate layer, (A) a surface layer of a thermoplastic resin, and (B) an intermediate layer of a thermoplastic resin sandwiched between the (C) substrate layer and the (A) surface layer, wherein the (B) intermediate layer contains 0 to 70 % by weight of a flake inorganic filler, the peeling strength between the (A) surface layer and the (B) intermediate layer is from 0.3 to 2.0 kg/15mm, and the peeling strength between the (B) intermediate layer and the (C) substrate layer is at least 1.2 times as large as the peeling strength between the (A) surface layer and the (B) intermediate layer.  When a packaging container is produced by forming the multilayer structure into a container body and sealing the container body with a lid, easy openability and high sealing property will be ensured because the opening of the packaging container is not operated by using the delamination between the sealed portion but by using the easy delamination between the surface layer (A) and the intermediate layer (B).  The use of the multilayer structure for production of packages is economically advantageous because the recovered scrap can be reused as the material for the substrate layer (C) without affecting the peelability of the surface layer (A).

Abstract: TRANSITION CONTROL SYSTEM FOR SPACECRAFT ATTITUDE CONTROL               ABSTRACT OF THE DISCLOSURE           A method for controlling transition from thruster control to momentum wheel control to minimize nutation angle and transition time in a three-axis stabilized spacecraft employing an internal body fixed-momentum wheel as an attitude stabilizer.  The method employs direct, substantially real-time measurement of momentum components and angular rates  and generates paired roll thrust impulses and paired yaw thrust impulses in synchronization with the nutation period of the spacecraft to drive the spacecraft to a state of substantially zero nutation.  The controller employs a deadbeat principle in a closed-loop real-time feedback system.   In a preferred embodiment, the impulsive thruster firing commands in roll and yaw are simultaneous, spaced one-half nutation period apart in time with the effect that the target momentum is achieved in one to three pairs of impulse firings.  The invention provides, with minimum transient overshoot, automatic reduction of angular momentum relative to a desired on-orbit state to a level which can be managed by a low-authority momentum wheel controller.

Abstract: A procedure for composting organic wastes, wherein the waste masses are placed in a composter. A drawback of all procedures of prior art for composting wastes is that altogether too much air is conducted into the composter through gaps and holes in its walls, whereby it either dries out easily or freezes in winter. In the procedure of the invention, the requisite breathing taking place through the walls of the composter is managed in a controlled manner by means of varying the material and thickness of the walls. The invention also concerns a composter for implementing the procedure, consisting of a space enclosed with walls (1), a bottom (2) and a cover (3) and in which the wastes are placed. The walls (1), at least, consist of thermal lagging sheets permeable to air, such as underdrain plastic sheets.
