  • Patent number: 4084603
    Abstract: A fluid-blending system supplies a constant preestablished ratio of two or more fluids through a common output conduit over a wide range of variations of the flow rate established through the output conduit by a pump controlling such flow rate. This constant ratio also is maintained in spite of variations in the different head pressures of the fluids supplied to the blender. Separate fluid supply chambers are used for each of the fluids to be blended and are connected in common to the output conduit. The inlet orifices for each of the fluid supply chambers are normally closed by diaphragm-controlled valves mounted in the chambers. The amount of valve opening is controlled by pressure-sensing diaphragms in response to a partial vacuum created by the demand for fluid in the output conduit.

  • Patent number: 4073328
    Abstract: An arrow quiver particularly suited for use by hunters and worn on the back comprises an open, elongated frame with an abutment at its upper end against which the arrow heads are pressed. The arrows are aligned and spaced from one another by a pair of bridges, the lowermost one of which has a number of spaced slots across it, each slot accomodating the shaft of an arrow. The slots are tapered so that they are narrower on the side facing the upper portion of the quiver and are made of resilient material which overlaps the shaft of an arrow pressed into the slot. The shape of the slots facilitates loading of the arrows into the quiver and sliding them upwardly to permit the heads to rest against the abutment. The taper of the slots, however, impedes movement of arrows through the slots downwardly away from the abutment to hold them firmly in place until removal is desired by pivoting the arrows outwardly out of the slots.

  • Patent number: 4072078
    Abstract: A tone pattern generating system for use with an electronic musical instrument, such as an electronic organ, responds to depression of a pedalboard key and a preselected rhythm and chordal pattern in an ROM memory to produce a "walking bass" automatically in response to continued depression of the selected pedal key. The ROM memory may be programmed to produce different tonal and rhythm effects in accordance with the wishes of the musician. In addition, provision is made for starting each rhythm and tonal pattern controlled by the ROM memory at the beginning of the pattern each time a new pedal key is played or released and replaying of the same pedal key is effected by the musician. The system also operates to immediately play the note selected by depression of the pedal key and prevents the production of tones under control of the ROM memory for a predetermined time interval following initial depression or operation of a pedal key.
