Abstract: PHN. 9063 26.4. 1978 ABSTRACT:           The application describes how information can optically be written in a round disc-shaped record carrier body along an information track, a write spot being accurately guided in the radial and tangential direction. The record carrier-body comprises a servo track which consists of servo areas, a constant and large number of servo areas per revolution of the servo track being provided. In the write apparatus, in addition to a write spot, a servo spot is projected on the layer to be written. The tangential speed and the radial position of the servo spot relative to the servo track are determined and with the aid thereof the tan-gential speed and the radial position of the write spot, which is locked to the servo spot, are corrected.

Abstract: TAG FOR IDENTIFYING LUGGAGE AND METHOD OF USING SAME     Abstract A kit fox marking, identifying and controlling the transport of luggage is comprised of a tag arranged for attach-ment to a piece of luggage and having located on its face one of a selected group of distinctive geometrical shapes which is colored in one of a selected group of colors and which has an alphanumeric character located within the borders of the geo-metrical shape.  Thus by having a large group of shapes, colors and alphanumeric characters, a very large number of identifying indicia is available, each of which is readily differentiable even at a distance and by an untrained observer.  As an aid in communicating the identification of a particular geometrical shape, color and alphanumeric character combination, a group of identifying letters is marked on the tag, with the letters being uniquely associated with the particular combination of geometrical shape, color and alphanumeric character located on the tag.  The kit also includes a user card having the same color geometrical shape and alphanumeric character as on the associated tag, and a post card having spaces for placement of the user's personal identification and addressed for return to the supplier of the kit.  The method includes attaching the tag to a piece of luggage prior to transport by a carrier, and returning the filled-in post card to the supplier.  After the luggage has been transported by the carrier the user can easily identify it and retrieve it from a baggage claim area due to the readily recognized identifying indicia located on the tag.  In the event that the luggage should become misplaced, the carrier and the supplier can cooperate to locate it and inform the user of its whereabouts by using the information indicated on the post card.

Abstract: PREPARING ZEOLITE NaA                        Abstract Zeolite NaA can be produced with a very short crystallization time, if an alumino-silicate gel of particular properties is prepared and heated at about 95°C. The gel which is prepared by combining solutions of sodium aluminate and sodium silicate must contain a limited amount of water, be of a single phase and have a high viscosity. Gels of this nature can be heated for a fraction of an hour to yield essentially completely crystallized Zeolite NaA with no crystalline impurities.

Abstract: ABSTRACT OF THE DISCLOSURE         A container for holding at least one recording disk includes a container base formed with a center opening and a disk holding space, and engaging and holding members movable between a first position for holdingly engaging the disk and a second position for being released from holding engagement with the disk, whereby the disk in the disk holding space can be pre-vented from being dislodged from the disk holding space when the engaging and holding members are in the first position.  The disk held in the container can be placed on a turntable of a disk playing system without requiring user's manual attention.  Such disk playing system includes, besides a turntable, a loading base, release pins, a disk cam formed with cam slots each for receiving one of the release pins, and a vertically moving screw engaged by a rotary nut.  When the disk container is placed on the loading base, the release pins move through the respective cam slots as the disk cam rotates to bring the release pins into engagement with the respective engaging and holding members, and move the latter to the second position in which they are released from holding engagement with the disk and allow same to be placed on the turntable.  Meanwhile the loading base is pivotally moved upwardly by the vertically moving screw as the rotary nut is driven, to move the container away from the disk and allow a pickup or the turntable to be selec-tively moved in a radial direction of the disk on the turn-table to play the disk.

Abstract: ABSTRACT OF THE DISCLOSURE         A flight vehicle toy includes a pair of vehicles driven about a support stand in a simulated race or "dog" fight through support arms which are rotated from a pair of coactial shafts in the support stand.  The toy vehicles are mounted on the support arms through a release mechanism such that when one vehicle impacts the vehicle in front of it during play the front vehicle will be disengaged from its support arm and propelled out of the game.  The speed of the respective vehicles can be independently varied by the players and the support arms are dimensioned such that the vehicles can pass above or below one another at all positions during play of the game, except when the vehicles are on a collision course.  And, a separate control for the drive motors rotating the arms varies the relative speeds of the two vehicles auto-matically during the game.
