Abstract: A ball louver assembly for controlling the direction of pressurized air passing through the openings of a ball shaped louver. The ball louver mechanism comprises a ball louver liner, which holds the ball louver and liner inside and between front and rear retainer rings. An inner ring attached to the back edge of the front retainer ring allows the ball louver with its attached liner to be turned in any rotational direction to direct the forced air as desired. The structure of the ball louver and the liner allows the ball louver to be turned into a position to close, reduce or select the direction of the pressurized air leaving the air conditioner through the openings in the ball louver body.

Abstract: An air directional louver device, which incorporates one or more multi-grooved ratchet style notches to cooperate with corresponding mating fixed pointer to mesh together. Once the rotating ratchet grooves on the louver's axles and one or more fixed knife-edge pointer are meshed, the louver can be held better in the last desired air direction set position than without the ratchet and pointer. The rotating ratchet will help prevent also vibration and/or the forced air to the louver or to the fixed knife-edge pointer area from moving the louver frame to another undesirable position. The fixed knife edge pointer, in another embodiment, will be rounded at its point for smoother operation and applied into the louver's corresponding holding area. Further change in the friction to change the louver position from one notch to another is attained by rounding the point and deepening the notches if desired.

Abstract: Apparatus for managing data and data requests within an associative memory device, wherein the associative memory device is responsive to requests from one or more using devices, such as a digital computer, to store, locate, retrieve, and modify, by means of decision logic, specific data which is stored in peripheral memory. The apparatus includes a number of elements which individually are capable of performing a number of general-purpose functions, which are in turn combined in specified sequences to form special-purpose functions. The special purpose functions and several of the general-purpose functions together provide the necessary data management capability for the associative memory device.

Abstract: An apparatus for searching stored data in accordance wit a search specification established by a digital computer. The data is stored in data tracks which form the storing medium on a memory device. The data is in the form of logical records, each record comprising a number of data fields. The search specification designates one or more of the data fields as range fields and may designate one field as a value field. The search specification also includes range field values and range field operators for each designated range field, and a value field operator for the designated value field. The apparatus includes a first processor, which comprises a variable number of first subprocessors equal to the number of data tracks simultaneously applied to the input of the apparatus. Each first subprocessor is operative to apply the range field values and operators against the designated range fields, and may also apply them against the designated value field, of each successive record in a data track.
