a collet removing device which is meshed with one of the shank and the collet, is engaged with another thereof in an axial direction, can take and remove the collet from the taper hole of the shank in accordance with a screwing operation for one of the shank and the collet, and can be separated from the shank and the collet.
2. A cutting tool attaching and detaching apparatus of an ultrasonic vibration machining device as claimed in claim 1, wherein said collet is provided with a screw portion meshed with the collet removing device, and said collet removing device can abut with an end surface of the shank.
3. A cutting tool attaching and detaching apparatus of an ultrasonic vibration machining device as claimed in claim 1, wherein said collet attaching device and said collet removing device are integrally formed so as to be used in a shape of a collet attaching and removing device.
4. A cutting tool attaching and detaching apparatus of an ultrasonic vibration machining device as claimed in claim 1, wherein said collet is provided with a ring groove which can engage and attach a collet removing piece, and the collet removing device can mesh with the shank and abut with an end surface of said collet removing piece.
5. A cutting tool attaching and detaching apparatus of an ultrasonic vibration machining device as claimed in claim 4, wherein a depressed recess is formed on the abutting surface of said collet removing device with the collet removing piece, so that the outer diameter of the end surface of the collet removing piece can sit on.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A portable compression chamber comprising two end walls interconnected by a flexible tubular member to form an enclosed space for receiving a person to be treated, the flexible member being formed by an inner air-impervious material surrounded by tube of a seamless woven material.
2. The chamber according to claim 1 wherein the tubular member has first and second ends, each end being held by respective first and second clamping means.
3. The chamber according to claim 1 wherein the end walls are annular and rigid, at least one of the first and second clamping means having a normal diameter that is less than the diameter of the end walls (10) and being expandable to allow an end wall to be inserted into an end of the tubular member before reverting to said normal diameter.
4. The chamber according to claim 3 wherein the at least one clamping means engages the associated end wall, after said insertion, and an air impervious seal is formed between said tubular member and the end wall.
5. The chamber according to claim 4 wherein an annular seal is compressed between the tubular member and the end wall to provide an air-tight seal.
6. The chamber according to claim 3, wherein the at least one clamping means is formed by a plurality of circumferentially spaced clamping segments together forming a clamping ring, the segments being able to be expanded radially outwardly relative to one another to increase the spacing therebetween to allow the insertion of an end wall.
7. The chamber according to claim 5 wherein each segment (24, 25, 26) is arcuate in shape.
8. The chamber according to claim 7 wherein each segment includes a first clamp for clamping the inner material and a second clamp for clamping the seamless woven material.
9. The chamber according to claim 8 wherein the first clamp is formed between an inner clamp plate and an intermediate clamp plate and the second clamp is formed between the intermediate clamp plate and an outer clamp plate.
10. The chamber according to claim 9 wherein the inner, the intermediate and the outer clamp plates are compressed together by fixing means.
11. The chamber according to claim 10 wherein the fixing means is a plurality of screws.
12. The chamber according to claim 6 wherein the seamless woven material extends through the second clamp to the associated end of the member and passes around a radially inexpandable end member before passing through the second clamp in a reverse direction.
13. The chamber according to claim 12 wherein the radially inexpandable end member has a diameter that is smaller than the diameter of the associated end wall.
14. The chamber according to claim 12 wherein the end member is flexible.
15. The chamber according to claim 12 wherein the end member is formed by webbing.
16. The chamber according to claim 15 wherein the webbing is formed by a plurality of annular strands of webbing.
17. The chamber according to claim 16 wherein the strands are contained within a tube.
18. The chamber according to claim 12 wherein the at least one end wall has an outer circumferential surface that is convex in planes including the axis of the end wall, the convex outer surface facing the associated end of the member, the member extending around said surface with the end member being radially inwardly of said convex outer surface.
19. The chamber according to claim 12 wherein the seamless woven material after passing back through the second clamp, terminates in an end, the end of the seamless woven material being formed with a portion of increased thickness to resist the seamless woven material being drawn back through the second clamp.
20. The chamber according to claim 1 wherein a tubular outer cover is provided over the member.
21. The chamber according to claim 20, wherein the tubular member has first and second ends, each being held by first and second clamping means and wherein the outer cover has first and second ends, each end being clamped by a respective one of the clamping means.
22. The chamber according to claim 20 wherein each segment includes a first clamp for clamping the inner material and a second clamp for clamping the seamless woven material and wherein the cover is clamped by said first clamp (24, 25).
23. The chamber according to claim 1 wherein at least one hoop is provided between the ends of the member to support the member.
24. The chamber according to claim 1 wherein each end wall includes a transparent cover.
25. The chamber according to claim 1 wherein at least one end wall includes a closable access.
26. The chamber according to claim 1 in combination with a supply of oxygen under pressure connected to the interior of the chamber.
