Title: Concrete repair agent injection plug and connector
Inventor: NAITO NOBORU
IPC: E04G23/02
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To enhance workability by providing a tip side small diameter injection pipe whose outer periphery is surrounded with a compressible elastic body and a root side large diameter injection pipe with a back flow preventive mechanism. SOLUTION: A concrete repair agent injection plug 10 comprises a small diameter tip side injection pipe 11 provided with a fixing mechanism 13 and a large dia-root side injection pipe 12 provided with a back flow preventive mechanism 14. The pipe 11 and the fixing mechanism 13 are inserted into an injection hole provided on a wall surface to be repaired and a snap ring 13b is moved forward, thereby compressing a gasket 13a by way of a sleeve 13c and expanding in the radial direction and fixing the plug 10 with the injection hole. Then when a concrete repair agent is pressurized and injected, the repair agent moves the sheet 14a downward against a pushing force of a coil spring 14b so that it may flow into a void in the concrete from the pipe 11. After the repair agent is cured, the snap ring 13b is moved back, thereby reducing compressively the dia of the gasket 13a and pulling out the plug 13 for disposal. The construction makes it possible to reduce the dia of the injection hole and minimize repair traces which might damage the beauty of the repaired wall surface.

Title: Production of sandwich glass
Inventor: HORI TOSHIHIKO
IPC: C03C27/12
Filed: 1990-10-09
Abstract: PURPOSE:To inexpensively obtain a sandwich glass which is free from bubbles and is clean with high productivity by placing many cord-shaped plastisols in parallel between glass plates and compression-bonding these plates under heating after a specific treatment. CONSTITUTION:The many cord-shaped plastisols of 10,0000 to 1,000,0000cp viscosity are placed in parallel at certain intervals between >=2 sheets of the glass plates. These plastisols are so formed that the diameter of the cord-shaped bodies is max. in the central part in the longitudinal direction of the cord-shaped bodies and decreases uniformly in both peripheral directions. The glass plate surfaces are so pressurized that the cord-shaped bodies are made into the films of a prescribed thickness by rolling. The cord-shaped bodies are then compression-bonded under heating by which the desired sandwich glass is obtd. The operations for washing, drying, cutting, humidifying, etc., associated with the handling of the films, are saved by the above-mentioned method, and since the handling in a closed system is possible, the need for a large-scale clean room is eliminated. In addition, the clean sandwich glass which is free from the intrusion of the bubbles is produced at all times.
