Abstract: A compact disk changer includes a magazine having an inner body and an outer body that are rotatable independently of one another about a common axis of rotation. The inner and outer bodies are slideably interconnected by a helical member so that relative rotation between the bodies in a first direction increases the axial spacing between them and relative rotation in a second direction decreases the axial spacing. This construction reduces the size of the changer and does not require precision tolerances between moving parts. A plurality of compact discs are stacked within the magazine, and each disk is supported by a disk holder. When the disk at the top or end of the sack is to be played, relative rotation between the inner and outer bodies creates an axially extending space adjacent the selected disk and a playing mechanism is inserted into that space.

The operation is thus simple, less movement of eyesight is required, no operation error is committed, and a large number of cameras can be connected with a small-size and easily operable system.

Abstract: A low cost building is made of modular parts in the absence of special tools. Light-in-weight wall blocks having a facade of conventional appearance include a thick, insulating mixture of a cementitious material, polystyrene, and organic fiber aggregates capable of retaining water. The blocks have interlocking top and bottom surfaces so that they are easily stacked to form walls. A floor is built by spanning foundation beams with floor trusses that have a key along their respective tops and by sliding modular floor panels between contiguous floor trusses, each floor panel having opposite edges that slidingly engage the keys of the floor trusses. A roof is made in a similar manner by sliding modular roof panels between contiguous roof trusses. Tensioning rods are extended from a top surface of the walls to the building foundation to compress the walls.

Abstract: An automatic apparatus that positions a golf ball on a tee retrieves and positions a new ball on the tee each time a golfer makes a tee shot. A bucket of balls is charged into the apparatus, and a ramp directs the balls, one at a time, to a tee loading station. A plunger drives a ball in the tee loading station into contact with a horizontally positioned tee. The tee has a bore formed in it that communicates with a source of negative pressure so that a ball driven into contact with the tee by the plunger is held to the tee by a vacuum. The resulting increase in a vacuum line reconfigures a four way valve and activates a mechanism that rotates the tee and ball into a vertical position so that the golfer may make a tee shot. The shot disconnects the ball from the tee, resulting in bleeding of the vacuum line, and the drop in pressure reconfigures the four way valve. The valve activates a mechanism that returns the tee to its horizontal position so that it may retrieve another ball from the tee loading station.

Abstract: A sonar, lidar, or radar system generates an alarm signal if a child enters a swimming pool when the system is enabled, and includes multiple safeguards against sounding false alarms due to wind-activated waves in the pool or self interference arising from multi-path propagation of the sonar signals. An acoustic or electromagnetic receiver having a narrow bandwidth is employed to demodulate a composite signal spectrum produced by a target object such as a child and signals generated by wind-activated waves. It also performs an envelope amplitude monitoring function to suppress false alarms that might be generated by low amplitude envelopes of the type created by self interference. In a first embodiment, an alarm signal is generated only if the demodulating function and the envelope amplitude monitoring functions both indicate a legitimate alarm.

Abstract: A digital frequency synthesizer employs a predetermined residue number system to generate phase angle information. The phase angle information is then converted from the predetermined residue number system into a weighted binary number. A part of the weighted binary phase angle information is used to address a read only memory that includes predetermined initial data points at each address. A predetermined iteration process that makes use of some or all of the weighted binary phase angle information that was not used to address the read only memory is then employed in an iterative process to generate final data points for the predetermined waveform. The initial data points are stored in the read only memory as weighted binary numbers and the iterative process employs weighted binary arithmetic. A second embodiment stores the initial data points in the read only memory as digits from a predetermined residue number system and the iterative process employs residue number system arithmetic.

Abstract: An air conditioning system includes a self-regulating flow controller having no moving parts that provides a liquid seal between a purge vessel and the evaporator barrel of a chiller. Circulating refrigerant fluid from a primary air conditioner is preheated in a preheater by hot refrigerant from the chiller prior to its entry into the purge vessel, and the preheater provides a thermal load that enables operation of the purge vessel. The purge unit discharges into a regeneration cell that removes even more refrigerant from the vapors before they are vented to atmosphere. When the regeneration cell requires recharging, it is heated to a predetermined temperature and pressure to release adsorbed refrigerant from its adsorption media, and the released refrigerant is routed back to the purge vessel and hence through the regeneration cell again prior to discharge of substantially refrigerant-free contaminants into the atmosphere.
