Abstract: A method and apparatus for crushing waste gas cans between a pair of rotating rollers installed in a treatment chamber and removing the residual gas and residual liquid from the waste gas cans. The atmosphere in each of a waste gas can loading chamber, which is adjacent to the treatment chamber, the treatment chamber and a discharge chamber is replaced with an inert gas, thereby maintaining the oxygen concentration in the treatment chamber within a low range in which the residual gas will not burn explosively. Crushing of the waste gas cans is carried out while the oxygen concentration in the treatment chamber is within the low range. The pair of rotating rollers have two rotating shafts disposed approximately parallel to each other and sprocket wheels disposed on each rotating shaft at regular spacings.

Abstract: A system of processing big refuses such as spring-containing mattresses according to the present invention includes a crushing process for crushing big refuses such as spring-containing mattresses by a single axial crusher capable of crushing them into a certain particle size or less, a magnetic-force grading process for grading iron material by a magnetic-force grader from crushed pieces crushed in said crushing process, and a wind-force grading process for removing light-weight refuses such as fiber adhering to iron material graded in said magnetic-force grading process by a wind-force grader.

Abstract: A cuff presser which enables even an inexperienced operator to easily remove a shirt from a sleeve stretcher without wrinkling its sleeves and cuffs. The cuff presser has a cuff pressing member including two separate hollow cylindrical members. A cylinder is mounted in the cylindrical members. It has a rod pivotably carrying at its tip a pivot plate. A rod of another cylinder is mounted to the pivot plate. A leaf spring is fixed to the pivot plate. The pivot plate is pivoted by extending the second cylinder to open and close the leaf spring, which protrudes outwardly from a groove formed in the side of one of the cylindrical member, relative to the side face of the cylindrical member. The cylindrical member against which the leaf spring is pressed is moved by the first cylinder away from the other cylindrical member, on which is fitted a cuff.

Abstract: A trouser presser includes a trouser carrier for holding a pair of washed trousers in a desired attitude. The trouser carrier includes a waist pad for receiving the waist portion of the trousers to shape it and a bottom stretcher for receiving the bottoms of the trousers to stretch them. Heat plates are provided for pressing from both sides the pair of washed trousers to dry them. A first drive is provided for moving the trouser carrier up and down, and a second drive for horizontally reciprocating the trouser carrier between a trouser loading position and a trouser press position.
