Title: Device for storing audio media and/or disk-shaped data media
IPC: G11B33/04
Filed: 1998-07-03
Abstract: An apparatus for the storage of disc sound and/or data carriers having a substantially rectangular flat housing that defines a receiving space that is accessible through a slot in one side of the housing. The housing also includes mutually oppositely disposed guide elements which receive a disc inserted through the slot and which keep it spaced from the housing surfaces. An ejection mechanism is mounted in the housing that includes a pivotally mounted lever arrangement. The ejection mechanism urges the disc through the slot such that it extends beyond the housing and may be grasped by a user. A braking and guide strip arrangement is provided in the flat housing adjacent to the slot opening. The strip arrangement extends over the width of the slot opening and includes at least two mutually and oppositely disposed strips. The spacing of the opposing strips is such that the center region of the slot opening has a spacing that is greater than the thickness of the disc. The spacing of the strips reduces towards the ends of the slot and is smaller in the region of the slot ends than the thickness of the disc.

Abstract: PURPOSE: A refrigerant tube cutting transfer equipment is provided to promptly transfer a refrigerant tube clamped onto clamp units as long as a uniform length unit by converting cyclic alternating and rotational motions of a disk into cyclic alternating and straight line motions of transfer belts by connecting rods. CONSTITUTION: In an equipment for cutting a refrigerant tube in a certain length unit, the refrigerant tube cutting transfer equipment comprises a rotational disk(8) which is formed on the lower part of transfer belts(9) transferring clamp units(7); connecting rods(10) connecting the disk(8) to the transfer belts(9); a forward and reverse motor which is periodically reciprocated and rotated in both directions; timing pulleys conveying the reduced speed to the driving shaft by reducing speed of cyclic alternating and rotational motions of the forward and reverse motor; and a driving shaft connecting the timing pulleys to the disk(8), wherein the refrigerant tube cutting transfer equipment further comprises a transfer length control device for the refrigerant tube consisting of a screw(17) supporting and connecting the clamp units(7), nuts formed between the clamp units(7), a fastening unit(16) controlling distance between the clamp units(7) by rotating the nuts, and a control motor(15) for rotating the fastening unit(16).
