Abstract: There is provided an organic waste processing device comprising: an organic matter-receiving container defining an organic matter-receiving chamber; a gas-propelling unit; a gas-plenum chamber in gas communication with the gas-propelling unit; and a grinding assembly at least partially contained in the organic matter-receiving chamber. The grinding assembly comprises a drive shaft and a rotatable blade assembly including a blade support sleeve mounted to the drive shaft and being engaged in rotation therewith. The rotatable blade assembly further includes at least one blade mounted to the blade support sleeve. An inner surface of the blade support sleeve is spaced-apart from an outer peripheral surface of the drive shaft to define a gas flow channel extending longitudinally into the griding assembly and providing gas communication between the gas-plenum chamber and the organic matter-receiving chamber.

Abstract: A system and method for preparing a shelled crustacean body part for meat extraction are provided. The method involves capturing an image of said body part, evaluating the thickness of the shell from the image, determining from the thickness evaluation at least one laser parameter for forming a line of weakness within the shell, the line of weakness being dimensioned to facilitate meat extraction, while preserving the sensory characteristics of the meat, and sweeping a laser beam on the body part in accordance with the laser parameter to form the line of weakness within the shell. The method and system provide the advantage of facilitating meat extraction without compromising the quality or commercial value of the meat all while increasing productivity and performance in comparison with completely manual extraction techniques.

Abstract: A sun-tracking light distributor for a photosynthetic culture in an aqueous liquid, comprising: two light distribution walls made of a transparent material, creating an elongated V-shaped channel adapted to receive the sunlight and to be partly immersed in the aqueous liquid, the sun-tracking light distributor has a center of buoyancy, a vertical passing through the center of buoyancy defines an axis of flotation, and a pivot axis of the sun-tracking light distributor is offset relative to the axis of flotation. Owing to the offset pivot axis, the orientation of the light distributor is changed by varying the level of aqueous liquid, thus allowing a tracking of the sun's altitude.

Abstract: A sun-tracking light distributor system for use in an open-ended photo-bioreactor having an aqueous liquid for a photosynthetic culture, comprising: at least one light distributor each including a concentrator supporting section with a light entry surface adapted to receive sunlight rays, an elongated rod section with a light distribution surface adapted to redirect the received sunlight rays within the aqueous liquid, a light concentrating element provided at the light entry surface which concentrates within the elongated rod at least a portion of the sunlight rays received at the light entry surface; a displacement system operatively connected to the light distributors and adapted to change an orientation of the light entry surface of the light distributors to track a solar position.

Abstract: A method for inserting a component through a surface of a workpiece made of a first material uses friction-induced plasticity of the latter to attach the component to the workpiece. The component includes a head portion having a base and a working end being threaded, and an insert portion having a penetrating end and provided with a threaded bore closed at its penetrating end, to initially receive the threaded working end. The outer surface of the insert portion being made of a second material harder than the first material, a rotary tool can be used to insert the component through the workpiece surface, by rotating the rotary tool in a first direction while applying an axial force onto the head portion base to produce substantially full insertion of the insert portion, and by maintaining the axial force during a sufficient setting time without rotation to produce the attachment.

Abstract: A rotary tool (11) for use with a rotary driving unit (12) for inserting a component (14,14?,14?) through a surface of a workpiece made of a material showing friction-induced plasticity such as aluminum, includes a tool body (22) having a working end (24) defining a shoulder portion (26) and a securing device (28,28?) for selectively engaging the component to impart rotation thereof in a first direction while applying an axial force of a sufficient magnitude onto the component to produce insertion thereof by plasticizing the material through friction. The shoulder portion is provided with a deburring device (34) capable of being displaced from an inoperative position upon rotation of the tool body (22) in the first rotation direction (30), to an operative position whenever the tool body is caused to rotate in an opposite direction (30?), to provide deburring of the workpiece surface.
