Abstract: A time-release composition and method of making and using the time-release composition. The time-release composition may include an active ingredient that is useful in deterring unwanted growth, such as bacterial and fungal growth, in high-flow water environments. The composition can include several active ingredients to provide a multiple use tablet. The multi-use tablet can be used to dispense any combination of active ingredients that act as clarifiers, minerals, medications, buffers, chemical dosing, and/or other maintenance components, such as growth deterrents and water filtration augmentation and any combination thereof.

Abstract: Animal chews are generally formulated with a composition that generally comprises a combination of protein, carbohydrate, fiber, fat, humectants and water, which is formed by mixing, followed by a forming process, such as molding. As described herein, animal chews are made having an outer portion and an inner portion. The inner portion is contained within recesses within the outer portion and can also include runners giving the appearance of a tied rawhide bone.

Abstract: A filter including a filter housing having a spillway and a pneumatic intake assembly that draws water from an aquarium into the filter housing. The filter housing being configured to internally mount to the aquarium. The filter housing having first and second chamber oriented in a side-by-side arrangement such that water flows in a generally horizontal direction through a filter cartridge positioned between the first and second chambers.

Abstract: An aquarium filter arrangement including a filter housing and a filter cartridge positionable within a filter chamber of the filter housing. The filter arrangement includes a hinged cover connected to the filter housing. The hinged cover is designed to collect condensation when the cover is in an open position, and empty the collected condensation into the filter chamber when the cover is closed. The filtering housing also includes guides located above the filter chamber. The filter cartridge can be positioned within the guides during maintenance of the aquarium.

Abstract: An impeller, and impeller and rotor assembly, for use with a permanent magnet motor that provide uni-directional rotation. The impeller and rotor assembly includes an interconnecting arrangement and a locking arrangement that permit continuous rotation in a first direction and prevent continuous rotation in a second opposite direction.

Abstract: A portable heater of the type having a housing containing an internal fan and heating element to force heated air out of a blower opening is disclosed herein. The heater housing includes a plurality of foot-operable, push-button switches mounted on an outlet face, and the housing is of a horizontally stable configuration. A fulcrum, which also may be utilized as a carrying handle, is also disclosed to assist in foot-operation of the switches, and an angled outlet face is disclosed to direct heated air from the housing.

Abstract: Multiplexed serial data from the keyboard of a musical instrument, such as an electronic organ, is delayed in a shift register to cause generation of musical tones related to the keyswitches closed on the keyboard and combined with the non-delayed serial data for producing mutation voices or chords.

Abstract: A non-volatile memory system for an electronic musical instrument having a plurality of player actuatable instrument controls, comprises a readable, writable memory. The memory includes addressing inputs and data input/outputs. The data input/outputs are coupled with at least selected ones of the plurality of player actuatable instrument controls. Player actuatable memory controls are also provided for selecting either the memory or the selected ones of the player actuatable instrument controls for control of the instrument.

Abstract: A touch responsive tonal envelope waveshape control system is provided for an electronic musical instrument which includes cooperating tone generating and keying circuits which are responsive to actuation of a key for initiating the generation and keying of a corresponding tone. The system of the invention includes encoding circuits responsive to the actuation of a key for producing encoded signals corresponding to the intensity of player actuation of the key and an amplitude control circuit responsive to these encoded intensity signals and cooperative with the keying circuits for controlling the peak amplitude of the tonal envelope waveshape in accordance with the intensity of player actuation of the key for initiating that tone.

Abstract: A large scale integrated circuit chip is provided with internal tone generators and digital attack and decay features interconnected with external capacitors for controlling the attack and decay of tones. External diodes are wired to the chip and to the external capacitors and have a circuit completed by a damper switch. According to the position of the switch the capacitors will discharge slowly for long sustain of tones, or will discharge very rapidly through an additional discharge path on the chip upon key release to produce very rapid decay.
