Title: Electrically resistive heating element having temperature control.
Inventor: CARTER PHILIP S
IPC: H05B6/00
Filed: 1981-03-02
Abstract: There are many situations requiring temperature regulation in heating elements which the prior art feedback control systems are not capable of handling adequately. In order to provide a temperature regulation in a narrow range around the Curie temperature, the heating element of the present invention is consisted of a substrate (35) or core (7) (25) of a nonmagnetic material having high thermal and electrical conductivity, clad with a surface layer (9) (27, 37) of a ferromagnetic material of relatively low electrical conductivity. When the heating element is energized by an electrical source (3) of high frequency alternating current, the skin effect initially confines current flow principally to the surface layer of ferromagnetic material. As temperature rises into the region of the Curie temperature of the ferromagnetic material, however, the decline in magnetic permeability of the ferromagnetic material causes a significant lessening of the skin effect, permitting migration of current into the high conductivity non-magnetic core, thereby simultaneously enlarging the cross-sectional area of the current flow path and expanding it into the highly conductive material; the resistance of the heating element becomes less due to both causes. By selecting the proper frequency for energization, by regulating the source to produce constant current, and by selecting dimensions and material parameters for the heating element, temperature regulation in a narrow range around the Curie temperature of the ferromagnetic material can be produced, despite considerable fluctuations in thermal load.

Title: Apparatus and process for making solar grade silicon.
Inventor: LEVIN HARRY
IPC: C01B33/03
Filed: 1983-06-20
Abstract: A reactor apparatus (10) adapted for continuously producing molten, solar grade purity elemental silicon by thermal reaction of a suitable precursor gas, such as silane (SiH4). The reactor apparatus (10) includes an elongated reactor body (32) having graphite or carbon walls which are heated to a temperature exceeding themelting temperature of silicon. The precursor gas enters the reactor body (32) through an efficiently cooled inlet tube assembly (22) and a relatively thin carbon or graphite septum (44). The septum (44), being in contact on one side with the cooled inlet (22) and the heated interior of the reactor (32) on the other side, provides a sharp temperature gradient for the precursor gas entering the reactor (32) and renders the operation of the inlet tube assembly (22) substantially free of clogging. The precursor gas flows in the reactor (32) in a substantially smooth, substantially axial manner. Liquid silicon formed in the initial stages of the thermal reaction reacts with the graphite or carbon walls to provide a silicon carbide coating on the walls. The silicon carbide coated reactor is highly adapted for prolonged use for production of highly pure solar grade silicon. Liquid silicon (20) produced in the reactor apparatus (10) may be used directly in a Czochralski or other crystal shaping equipment.

Patent EP-0340236-A4 (EP)
Title: Improved pump construction
IPC: F04D29/22
Filed: 1987-12-22
Abstract: A pump is provided within a vortex generator having a plurality of equally spaced blades which rotate in a pump casing to form a nucleus of fluid in the shape of an ellipsoid having an upper tapered end and a lower tapered end with a thicker central section at the blades. Fluid flows in a synchronized flow from the lowered tapered end of the nucleus in a rotating vortex column of fluid which initially flows out of the pump inlet to swirl the ambient fluid about the inlet and causes a low pressure area and a swirling of the ambient fluid to flow inwardly through the pump inlet in a direction counter to the vortex column flow. A belt of fluid rotates between the nucleus and the pump casing. The blades are curved to retain fluid in the nucleus and momentum energy is cumulatively applied to keep the swirling column of fluid swirling through the pump outlet. A tapered section on the pump between the pump inlet and pump outlet assists in flow therebetween. A divider may be provided in the pump casing with an opening in the divider to allow the vortex column to flow from a vortex generating chamber to a pump discharge chamber while debris hits the divider and is prevented from flowing into contact with the blades. Pressure boosters may be added to the blades.
