Abstract: A disk or rotor for a disk brake system is formed of a number of stacked metal plates, normally with outside plates having a high resistance to abrasion and great strength and with inner plates formed of metal having good heat transfer characteristics and having inside and outside rims and generally radially directed slots between the rims, the inner plates being aligned such that the slots are held in registry, and all of the inner and outer plates are brazed together to form a unitary disk. Inside and outside diameters are then both trimmed to remove the rims and open the slots between fins formed when the inside and outside rims are cut away. One or more outside plates on one end of the stack are trimmed to a smaller diameter thus leaving a flange which is drilled to provide mounting holes for the disk. Modified forms of the disk include solid inside plates and inside plates with perforations or corrugations.

Abstract: A light system includes a laser light generator and an array of motor-driven mirrors aligned to deflect a beam of laser light in various directions to create a light show. The motors are operated in a controlled sequence by a motor controller. The motors are small d.c. permanent magnet motors which are driven from a d.c. source whose voltage is adjustable to vary the frequency of oscillation of the motors and, hence the mirrors. Connected to each motor is a small coil spring whose coil is carried on the motor shaft and which has two extended arms, one of which is secured to a nearly stationary member and one which is secured to the mirror shaft. The mirror shaft is movable between two stops. The spring acts to oppose the direction of motion of the motor such that the motor is normally stalled out and driven back to one of the stops before it can be moved for enough to impact the other stop.

Abstract: There is disclosed herein an invention which relates to the fields of genetic engineering, microbiology, and computer science, that allows a user, whether they be a molecular biologist or a clinical diagnostician, to calculate and design extremely specific oligonucleotide probes for DNA and mRNA hybridization procedures. The probes designed with this invention may be used for medical diagnostic kits, DNA identification, and potentially continuous monitoring of metabolic processes in human beings. The key features design oligonucleotide probes based on the GenBank database of DNA and mRNA sequences and examine candidate probes for specificity or commonality with respect to a user-selected experimental preparation. Two models are available: a Mismatch Model, that employs hashing and continuous seed filtration, and an H-Site Model, that analyzes candidate probes for their binding specificity relative to some known set of mRNA or DNA sequences.

Abstract: An electronic musical instrument is designed in a generally guitar-shaped configuration with a fingerboard containing rows of keys replacing each string, one key for each string/fret position. Pressing on a key causes a signal to be provided to a central processing unit which continually scans the fingerboard at a high rate and converts the signals to a plurality of outputs to a synthesizer. Unlike a guitar, a plurality of keys, including a plurality along a single row, may be operated simultaneously to produce a plurality of notes simultaneously. A number of pressure switches and other switches located on the body enable a player to modify the output with vibrato, pitchbend, stereo pan, percussion effects, etc. Additional pressure responsive circuits provide inputs to the central processing unit varying with pressure on the keys. A second embodiment includes a fingerboard with many more rows or columns of keys and more keys per column.
