Title: Engine for heat pump
Inventor: JIYO SHIYAKUKOU
IPC: F02B65/00
Filed: 1980-06-30
Abstract: PURPOSE: To increase collection efficiency of cooling heat and reduce radiation of heat and noise to the peripheral environment from an engine, by cooling the periphery of high temperature and heat generating parts of the engine with cooling liquid further directly covering an external wall of the engine with thermally insulating material.  
     CONSTITUTION: The periphery of high temperature and heat generating parts such as a cylinder head 5, cylinder 6, crankcase 8, bearing 7, muffler 11, etc. is cooled by cooling water flowing in the cooling water inlet 9 and outlet 10 of an engine and in the cooling water inlet 17 and outlet 18 of the muffler. Further external walls of these water jackets are directly covered by thermally insulating materials 15, 16. In this way, waste heat generated in the engine can be collected by cooling water, thus radiation of heat and noise from external surfaces of the engine to its surroundings can be prevented.

Title: Reducing and melting technique for rubber and plastic
Inventor: UMEMOTO MASAO
IPC: C08J11/12
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To soften and melt rubber and plastic safely in a short period of time. SOLUTION: High temperature inert gas, which is obtained by heating an inert body with a heat source, is obtained so as to expose plastics to the gas. In this case, there are two methods or a method for exposing to both the high temperature inert gas and the heat source and a method for exposing only to the high temperature inert gas. Or plastics are exposed to a mixture of gas flow emitted from a heat source and an inert body, resulting in reducing and melting the plastics. Or plastics are placed in a high temperature and inert atmosphere produced by feeding an inert body in a chamber having a heat source therein, resulting in reducing and melting the plastics.

Abstract: PURPOSE:To prevent not only the wear of a furnace bottom electrode but also the wear of the refractory of the electrode peripheral part by providing a protective sleeve formed from a material whose melt loss resistance is larger than that of the furnace bottom electrode and refractory on the periphery of the end part on the contact side with a molten metal of the furnace bottom electrode. CONSTITUTION:A protective sleeve 10 is provided at the end part on the contact side with a molten metal of a furnace bottom electrode 6, the part exposed to the upper surface of refractory 3a and the periphery of the part continuing to the exposed part to be embedded in the refractory 3a. The protective sleeve 10 has melt loss resistance higher than that of the furnace bottom electrode 6 and the refractory 3a and is not melted at the usual operating temp. of an arc furnace because of its high heat resistance. Even when the upper part 6a of the furnace bottom electrode 6 is melted, the refractory 3a of the electrode peripheral part is suppressed from the wear caused by the flow of the molten metal because the protective sleeve 10 holding the original shape is present. Further, the wear of the upper part 6a of the furnace bottom electrode 6 is also suppressed to a slight extent.
