Abstract: The invention relates to a process for carrying out reactions on preheated particles, comprising: (a) providing particles in a buffer container; (b) feeding the particles from the buffer container into a reactor via a feed line; (c) withdrawing the particles from the reactor, wherein the particles are heated in the feed line.

Abstract: Interposed between the cutting surface and the pressure head is a magnetic die holder including base and die carrying sections, the former being mounted on a telescoping member which is pivotally connected to the head for vertical movement therewith and which permits movement of the holder in a plane parallel to the cutting surface. The base and die carrying sections are connected by a spring to permit the die carrying section to be vertically displaced with respect to the base section for accurate positioning of the die relative to the cutting surface. The die carrying section is also rotatable relative to the base section to permit orientation of the die at any angle with respect to the cutting surface. The die carrying section includes an electromagnet which retains the die thereon. Also located on the die carrying section are a pair of handle grips, each having a switch mounted thereon, both of which must be simultaneously actuated in order to initiate vertical movement of the pressure head.

Abstract: Apparatus is provided for controlling the movement of a member, such as a pressure head in a die press, the die press being of the type wherein the pressure head is horizontally movable relative to the material to be cut or otherwise impressed to locate the head in the desired position above the material. Once positioned, the head is vertically movable into engagement with a die which is pushed through the material to perform the cutting or impressing operation. The apparatus includes means for moving the member in first and second directions along a horizontal plane, preferably in the form of an electrically controlled motor. Means are also provided for moving the pressure member vertically, preferably in the form of an electrically operated hydraulic system. First and second switch means, in the form of triggers or push buttons, are operably connected to both the motor and the hydraulic system and when actuated individually energize the motor to move the pressure member horizontally.

Abstract: A die press for performing operations on material includes a planar support upon which material is placed and a pressure member movable toward and away from the support. Means for moving the pressure member are provided as well as means for controlling the pressure member moving means. A die carriage upon which a die is mounted is situated between the pressure member and the support and is movable relative to the support in first, second and third directions, one of which is the direction of movement of the pressure member. The linkage for mounting the die carriage maintains the die carriage in the plane of the support throughout the movement thereof. For safety purposes the control means is situated on the die carriage at a portion thereof remote from the path of movement of the pressure member. Preferably, the control means includes a pair of switches which require simultaneous activation in order to energize the pressure member moving means.
