Abstract: An ornamental coating and process for applying the coating to a substrate includes mixing a first batch of liquid mortar composed of sand, cement and an aqueous solution of acrylic resin, and trowelling or spraying a first layer of the liquid mortar onto the substrate and allowing the liquid mortar to cure. A second batch of liquid mortar is mixed which is the same as the first except that it contains a color pigment contrasting with the color of the first batch. A template defining a pattern of grout lines is placed over the cured first batch and the second batch of liquid mortar is trowelled or sprayed over the first batch and the template as a second layer and allowed to cure only to the extent that the second layer is firm, but not hard. The template is then removed, removing that part of the second layer immediately above the template thus exposing lines of the cured first batch which then appear as grout lines between areas of colored mortar which appear as bricks, flagstone or tiles etc.

Abstract: A reservoir sight glass assembly forming part of a material transfer system for loading lightweight granular plastic material into injection molding machines and the like is connected to the associated machine and to a light weight pressure relief chamber attached to the reservoir sight glass assembly, both connections being by quick disconnect devices. The reservoir sight glass assembly includes a sensor adjustably positioned against the sight glass which responds to the level of material in the reservoir sight glass assembly and a magnet assembly which traps ferrous contaminants and prevents their entering the machine. The flow of material to the pressure relief chamber is controlled by the sensor which turns a regulated source of compressed air on or off depending upon the sensed level of material in the reservoir sight glass assembly.

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.

Abstract: A housing for use with a removable filter element includes fluid inlet passages and a fluid outlet passage, a plurality of arcuate slots arranged in a generally circular pattern on the housing, the housing including a valve body with bolts passing through the slots securing the valve body to the housing. A threaded boss is formed on the valve body for attachment of a filter element. A number of ports are formed on the valve body in registery with the fluid inlet passages for supplying fluid to the filter element. The boss includes a passageway therethrough communicating with the outlet passage and a check valve in the passageway. A seal is positioned between the housing and the valve body. Turning the filter element in a direction to remove it causes an initial rotation of the bolts in the slots resulting in misalignment of the ports and the fluid inlet passages, blocking flow to the ports.

Abstract: A fishing lure includes a generally cylindrical body with a head end and a rear section, the head end being of larger diameter than the rear section.
