Parallel reactor systems for synthesizing materials are disclosed. The reactor systems may include at least two reaction vessels and may be suitable for synthesizing materials produced from corrosive reagents, for example, Ziegler-Natta catalysts. Antechambers may be provided above the reaction vessels to help purge vapors produced by the corrosive reagents. Methods for preparing materials by use of such parallel reactor systems are also disclosed.

There are provided a straining mechanism and a screw extruder including the straining mechanism, which can minimize material passing resistance in a breaker plate even, in a large-sized apparatus having high throughput, and which can improve the throughput by suppressing load power of the apparatus and heat generation of a material. For this purpose, a backup plate having an opening rate higher than an opening rate of a breaker plate and supporting the breaker plate is installed on a rear surface side of the breaker plate supporting a screen mesh.

A system for capturing airborne particles from a mixing apparatus for mixing mineral based building materials, particularly such materials containing a silica based material, wherein there is a hood assembly attachable to a mixing apparatus and positionable such that airborne particles generated in loading the mixing apparatus are drawn into the hood, the hood being operatively connectable to a vacuum/filtration apparatus.

An apparatus and method for automatically preparing a mixture of particles of two or more substances such as but not limited to raw tobacco and raw medical cannabis flowers in one or more receptacle where the mixture proportion is predefined, is disclosed. The apparatus of the invention can be used for mixing any types of herbal substances. Moreover, the apparatus of the invention can be used for mixing one or more kinds of the same substance, for example mixing two or more kinds of marijuana strains. The apparatus includes one or more compartments for inserting each of the substances separately. In some variations of the present invention the size of at least one of the compartments is smaller for predefined smaller quantities of raw herbal material for example, a single marijuana flower.

A flask for containing mold sand within it prevents any mold shifting or mold dropping. Each of an upper flask 2 and a lower flask 3 includes a body that defines an opening in which a sand mold is to be molded. The body has at least one inlet 101 for introducing the mold sand into the opening. Two flanges 102 are extended from the body such that they are opposed to each other across the opening. Each flange has a through bore. The flask also includes engaging members for engaging an actuator in the outside of the flask such that a force or forces from said actuator could be transmitted to the flask. An upper flask 104 and a lower flask 105 are opposed to each other across a pattern plate 107. They are integrally assembled to make a flask unit by means of a pair of connecting rods 106 that are fitted in each bore.

A food processor can include a strainer, a sealing gasket, a blade assembly, and a lid. The food processor can be used in combination with a container such as a bowl or a flask, and in combination with an actuator. The actuator can be operated to actuate the blade assembly to rotate within the strainer to chop food items held therein, which can fall through the strainer into the container when they have been sufficiently chopped.
