Abstract: A case adapted to contain magnetic discs or the like, said case having a box-like containing member with a lid being hinge mounted to, and formed integrally with, the containing member. There is a tray to hold the discs in a displayed position where the tray slants upwardly and forwardly with the lid being fully opened. There is a linkage member comprising two linkage arms interconnecting the tray with the lid so as to cause upward motion of the tray. The tray further has a cam track and cam follower connection with the side walls of the case to program the motion of the tray to its proper display position.

Abstract: A slalom gate which has a lower support member adapted to be inserted into the snow. There is a retractable anchoring member mounted in the support member, in a manner that downward deflection of the post about a lower pivoting connecting portion pulls the anchor member upwardly to cause it to expand outwardly into the snow, thus resisting retraction of the support member from the snow. When the gate returns to its upright position, the anchoring member retracts so that the gate can more easily be removed from the snow.

Abstract: A cassette cleaner for a video player/recorder having a cleaning ribbon which comes into frictional engagement with the drum and playing head of the player/recorder. The ribbon has a contact surface with an alternating pattern of raised portions and recessed portions. This lessens the drag created by the engagement of the ribbon with the drum and playing head.

Abstract: A telescoping support post having a bell member slide mounted thereon to engage a mouth of a musical instrument in a manner to support the instrument. The inner telescoping member has a releasable holding member eccentrically mounted thereon. This holding member has a resilient finger frictionally engaging the inner surface of the outer telescoping member to insure proper locking and release action. In addition, the holding member has cooperating stop means to limit rotation between these two positions.A similar device is operatably positioned between the bell member and the upper telescoping member so that the bell member can be adjusted vertically on the second telescoping member and held in any selected position.

Abstract: A cassette-like housing having a cleaning ribbon mounted therein and wound on a pair of spools. The housing is adapted to be positioned in a playing location of a conventional playing/recording unit to operatively engage the video head and other components of the unit to clean the same. There is a cleaning cartridge to clean the capstan and pinch roller of the unit, and this cartridge is adjustable to be moved between two separate locations. In one location, the ribbon is between the capstan and pinch roller, and in the other location, it bypasses the capstan and pinch roller. There is also a mirror device to activate the shut off mechanism.

Abstract: A cleaning cassette for cassette recorders in which movement of either spindle of the cassette recorder operates a cleaning element within the cassette casing. Transmission of the rotary movement is achieved by a pair of rotatably mounted reel hubs and a pair of exterior toothed wheels, one integral with each hub, with the reel hubs coupled together by a third intermediate exterior toothed wheel to form a permanent gear train. For driving a cleaning element, such as a felt tab, the intermediate wheel drives a cam and lever. By rotating either toothed wheel, the intermediate wheel causes the lever to move the tab alternately back and forth substantially parallel to the front edge of the cassette casing.

Abstract: A cassette case adapted to be placed in the cassette recess of a video player/recorder. A cleaning ribbon is mounted in the case and is moved outwardly by tape-guides of the player/recorder to engage the video head and audio head of the player/recorder. To cause the cleaning ribbon to retract after the cleaning operation, there is provided a shut-off ribbon, operated by the drive spindle of the player/recorder, with the shut-off ribbon cooperating with the light/photocell already in the player/recorder. A tension ribbon is connected to the cleaning ribbon to move the cleaning ribbon out of engagement with the video playing/recording head and audio head to its retracted position.

Abstract: An apparatus and method for cleaning a digitally encoded disc by moving a circumferential wiping surface in a circular path across the periphery of the disc toward the middle of the disc, and again outwardly toward the periphery of the disc. This is accomplished by having a gear drive connection between a rotatable disc support member and a rotatable wiping member positioned above and offset to one side of the support member. Rotation of the cleaning member causes a relatively slower rotation of the support member so that all parts of the disc are properly cleaned.

Abstract: A device to clean and lubricate valves of a musical instrument, such as a trumpet. There is a casing having a pair of openings, one opening having a peripheral cleaning pad, and the other a peripheral lubricating pad. The valve is selectively inserted in both openings for cleaning and lubricating.

Abstract: A cleaning device comprising a cassette housing and a cleaning ribbon mounted on spools within the housing. With the housing inserted into a video unit, the guide members of the unit move the cleaning ribbon outwardly into an engaged position to clean the operating components of the video unit.

Abstract: A phonorecord cleaner is comprised of a handle member journalled for relative rotational movement with a phonorecord contact member, the latter including a phonorecord contact face having a wiping surface which is substantially equal to the radial dimension of the grooved recording band of a phonorecord, wherein movement of the cleaner in an arcuate path corresponding generally to the orientation of the spiral groove pattern maintains uniform contact of the wiping surface across the recording band of the phonorecord. A positioning member is preferably included to center the cleaner over the recording band and maintain proper orientation of the wiping surface with respect thereto during the cleaning operation.

Abstract: A cassette housing having a reciprocating wiper arm which comprises a front end cleaning section, a rear portion pivotally mounted to the housing, and an intermediate spring portion. The spring portion comprises three relatively rigid link sections joined to one another by two relatively flexible elbow sections, with the link sections extending generally laterally in a general "Z" configuration.

Abstract: A cartridge having a housing removably mounted in a cleaning cassette. The housing has a first pivotal connecting member to pivotally engage a matching connecting means in the structure, and a second connecting member adapted to engage second connecting means in the structure to prevent rotation of the housing. There is a fixed pad mounting member in the housing and a second pad mounting head movably mounted on spring arm.

Abstract: A "U" shaped mounting head in which is mounted a removeable retaining device adapted to retain a cleaning pad therein. The retaining device has sidewalls that fit against side surfaces of a recess of the mounting head, and an upper and a lower oppositely extending flange on opposite side walls to engage related upper and lower surfaces of the mounting head so as to be retained securely in the recess.

Abstract: A musical instrument support stand, adapted for storage substantially entirely within the hollow end of the musical instrument during periods of non-use, is comprised of a base including a tripod, a post secured at one end to the base and having a free distal end for projection within the interior of the musical instrument, and a musical instrument support received on the post and adjustable over the length thereof, wherein the outer geometry of the instrument support is complementary to the inner geometry of the musical instrument whereby the latter may be received by the former and supported thereon.
