Abstract: A magnetic tape cartridge is adapted for use in a magnetic tape cassette in lieu of a tape supply reel, such cassette also having a takeup reel for use of that cassette, after reception of the cartridge therein, in apparatus designed to receive magnetic tape in a two-reel-type cassette for transducing magnetic signals relative thereto. A single reel for the tape is in the cartridge, and a tape coupling device is on the magnetic tape at the cartridge for connection of the magnetic tape from the cartridge to the takeup reel. A coupling is on the cassette for interconnection of the magnetic tape from the cartridge via the coupling device to the takeup reel upon insertion of the cartridge loaded with the magnetic tape into the cassette in lieu of a tape supply reel.

Abstract: An interconnection of a first tape with a second tape has a first joint permitting angular movement of the first tape relative to a remainder of the interconnection about a first axis, and a second joint permitting angular movement of the second tape relative to a further remainder of the interconnection about a second axis parallel to the first axis. A stabilizing member is between the first and second joints. The interconnection is rendered disconnectable along the first axis extending through the first joint.

Abstract: This magnetic tape cassette system is usable in video and other tape cassette recorders, playback machines or other apparatus designed to receive magnetic tape from a two-reel-type cassette for transducing signals relative thereto. The tape has a first tape coupling device and is loaded into a one-reel-type cartridge. The cassette has a takeup reel which has attached thereto a second tape coupling device interconnectable with the first tape coupling device. The cassette has a space for receiving the loaded cartridge in lieu of a tape supply reel and for interconnection of the first and second tape coupling devices upon insertion of the loaded cartridge into that cassette space.

Abstract: An improved power operated vertically adjustable table which has a high degree of stability in any vertical position. The table comprises a lower support cage which rests stationary on the floor and acts as the main support for the table and an upper support cage which slides vertically within the larger lower support cage. A table top is attached to the ceiling of the upper support cage. Each of the cages comprise two round disks which are horizontally positioned, one above the other. The upper disks are inter-connected by a plurality of vertically positioned support rods; and the lower disks are similarly interconnected. When the table is in the lowermost or bottom locked position, the ceiling of the lower support cage is in contact with the ceiling of the upper support cage. When the table is in the uppermost or top locked position, the ceiling of the lower support cage is in contact with the floor of the upper support cage.
