Abstract: A light-weight unitary window assembly for recreational vehicles and trailers. The window assembly uses a two piece design that seats within the wall or door opening and incorporates a fixed window pane integrally molded into one of the polymer frame halves. The window assembly also uses a plurality of weep holes that extend through the frame halves to vacate water from the window assembly to the exterior of the vehicle or trailer wall. In an exemplary embodiment, the window assembly also includes a sliding window pane that slides along a peripheral track and securely seats in a closed position using a plurality of contact pads to prevent window “chatter.” The window assembly also includes an integrated latch mechanism to secure the sliding pane.

Abstract: The window assembly uses a releasable press fit frame connection. The window assembly includes a window pane sandwiched between a pair of frame halves that are press fit together by the engagement of a plurality of corresponding male and female connectors integrally formed into the frame halves. The corresponding male and female connectors are spaced apart around the perimeter of frame halves and hold the window assembly within the window openings cut in the wall or door panels. The window assembly of this invention also includes a release key that allows the frame halves to be taken apart. The release key is manually inserted through thin slots formed in the frame halves to disengage the connection between corresponding male connectors and female connectors.

Abstract: The present invention relates to methods of drying comprising an intentionally controlled increased negative static pressure level and drying systems using the same.

Abstract: The present invention is for a process for providing fluid bed drying of material in an intentionally higher negative pressure atmosphere in the area of the material being dried. This intentional negative pressure of an additional approximate minus 1 to minus 10 inches of water column or more of static pressure is greater than that which is encountered and inherent with standard engineering design of fluid bed drying equipment, accessories and auxiliary equipment or what is commonly referred to as atmospheric fluid bed drying. This will significantly decrease the drying times of most if not all solvent based granulations.

Abstract: An electronic ignition module for an internal-combustion engine that is supplied with sparking energy from a rotating magnet includes a switchable semiconductor device through which current in the primary of an ignition coil is to be conducted. A portion of a circuit in the module senses a time when voltage across the semiconductor device approaches a maximum value, and produces a signal at that time that switches the semiconductor device out of conduction. A positive-feedback circuit is connected to increase the switching speed of the semiconductor device. The semiconductor device is protected against AC voltages of a polarity opposite to that of the conducting direction of the semiconductor device, and is caused to advance switching time in response to increased voltages associated with high engine speed. A temperature-sensitive resistor performs temperature compensation on the module in response to the temperature of a hot engine to permit restart of the engine if it is stopped briefly.

Abstract: The invention relates to an electronic percussion-type musical instrument, such as an electronic piano, capable of producing electronically sounds simulating a piano, harpsichord or other keyboard percussion instrument. The keyboard is multiplexed to produce a serial time division multiplexed data stream having tri-level encoded signals in time slots corresponding to the keys, wherein the encoded signals indicate whether the key is undepressed, partially depressed or fully depressed. The amount of time for the key to travel in its undepressed to its fully depressed state is detected and a binary representation of the key velocity correlated to this timing is stored in a memory for readout synchronized with the scanning of the keyboard. In each time slot, a portion of the percussion envelope for the pertaining key is calculated and generated together with the discrete amplitude levels for the percussion envelope in a digital to analog conversion circuit.

Abstract: An electronic keyboard musical instrument comprising a multiplexed keyboard and a programmable microcomputer interfaced between the keyboard and a system of capture tone generators. The loading circuitry for the microcomputer, which is interposed between it and the keyboard multiplexer output, monitors the serial data stream and transmits only key change information to the microcomputer. The microcomputer controls the assignment and deassignment of tone generators for the accompaniment, solo and pedal manuals based on the key change information transmitted to it. Fill note information is taken from the captured accompaniment keyers and compared with the series of binary words for the current scan of the manuals in order to produce a keydown pulse when there is identity of pitch between the captured accompaniment tone generators and the scanning of the solo manual.

Abstract: An electronic keyboard musical instrument comprising a multiplexed keyboard and a programmable microcomputer interfaced between the keyboard and a system of capture tone generators. The loading circuitry for the microcomputer, which is interposed between it and the keyboard multiplexer output, monitors the serial data stream and transmits only key change information to the microcomputer. If a keydown signal appears in a time slot where that time slot was previously empty, a multiple bit binary word identifying that time slot and indicating that it is a keydown condition is transmitted to the microcomputer. Similarly, if a keydown pulse disappears from a time slot when a pulse was previously present, a similar code is transmitted to the microcomputer indicating that the key is no longer depressed. The microcomputer controls the assignment and deassignment of tone generators for the accompaniment, solo and pedal manuals based on the key change information transmitted to it.
