Abstract: A bicycle and light assembly has wheels, a frame support by the wheels, a bike light supported by the frame, and a mounting system coupling the bike light to the frame. The mounting system includes a socket secured to one of the frame and the bike light, a post secured to the other of the frame and the bike light, and a releasable securing mechanism that secures the post in the socket. The mounting system can further include a mounting bracket coupling the post to the frame, wherein the mounting bracket facilitates rotational adjustment of the post about the post axis. The releasable securing mechanism can include a detent member positioned in a side opening of the socket and in engagement with a recess in the socket to secure the rotational orientation of the post in the socket.

Abstract: A bicycle is disclosed comprising wheels, a frame assembly supported on the wheels and including a mounting portion defining a mounting axis, and a lighting system mounted on the mounting portion. The lighting system includes a power source and a lighting element having a lighting axis that is substantially parallel to the mounting axis. Preferably, the mounting axis is at an angle of 70-75 degrees relative to horizontal. The lighting system can further include a primary electronic board positioned substantially parallel to the mounting axis and a secondary electronic board positioned substantially perpendicular to the mounting axis. The lighting element is mounted on the secondary electronic board. The power source is preferably positioned between the primary electronic board and the mounting portion. The lighting system can further comprise a reflector positioned to receive light from the lighting element and direct a majority of the light in a substantially horizontal direction.

Abstract: This invention is an improvement to the shape of liquid storage tanks, in particular to unpressurized molded polymer tanks used for thermal storage in solar systems. All aspects of this invention are well suited to solar storage tanks, and individual aspects are suited to other liquid tank applications. This invention provides a formed horizontal extension at the bottom of the tank. From the top of this lower extension, a hollow vertical stub provides a reliable connection to a circulator pump. Thermal performance is enhanced by ensuring the lowest and coolest water is delivered to the array of rooftop solar collectors without entraining debris from the bottom of the tank. At the top of the tank, a similar horizontal extension is used to distribute hot water returning from the solar collectors. Flow velocity is eliminated and a curving lower edge allows return water to find the matching thermocline to avoid de-stratifying.

Abstract: This invention is an improvement to the shape of liquid storage tanks, in particular to unpressurized molded polymer tanks used for thermal storage in solar systems. Although solar storage tanks represent the first commercial application, this invention is well suited to ambient-temperature water and chemical storage tanks as well. By using a tank with a square footprint instead of a cylindrical tank, storage capacity can be increased by more than 20%, while consuming the same floorspace. For large indoor applications, doorway access amplifies the advantages of a rectangular tank versus cylinders. This invention combines the higher volume of square and rectangular footprint tanks with the structural efficiency of cylinder tanks. The tank walls are formed by alternating vertically-stacked cylinders and rectangular prisms. The cylinders take advantage of hoop strength and also provide a place for external reinforcing bands. Edges and corners may be sharp, chamfered or filleted.

Abstract: A roof top cooling unit has an evaporative cooling section that includes at least one evaporative module that pre-cools ventilation air and water; a condenser; a water reservoir and pump that captures and re-circulates water within the evaporative modules; a fan that exhausts air from the building and the evaporative modules and systems that refill and drain the water reservoir. The cooling unit also has a refrigerant section that includes a compressor, an expansion device, evaporator and condenser heat exchangers, and connecting refrigerant piping. Supply air components include a blower, an air filter, a cooling and/or heating coil to condition air for supply to the building, and optional dampers that, in designs that supply less than 100% outdoor air to the building, control the mixture of return and ventilation air.

Abstract: Firearm safety block devices and methods of use increase the pressured needed to pull back on triggers to cause a firearm to discharge the first shot A block member can be mounted on the firearm at different locations such as above, inside the trigger and behind the trigger. The invention can provide different block members having frangible areas that are broken or bent at selected side imposed pressures. Breaking, shearing or bending the block members is required to operate the firing mechanism as needed to cause the firearm to discharge. A spent frangible block member can be removed and replaced. When the firearm safety block is not applicable the block member can be removed.

Abstract: An evaporative heat exchanger having parallel plates that define alternating dry and wet passages. A water reservoir is located below the plates and is connected to a water distribution system. Water from the water distribution system flows through the wet passages and wets the surfaces of the plates that form the wet passages. Air flows through the dry passages, mixes with air below the plates, and flows into the wet passages before exiting through the top of the wet passages.

Abstract: A head disk assembly for a hard disk drive having a mechanical actuator latch subassembly. The head disk assembly includes an enclosure, a disk, a pivot bearing cartridge, and a head stack assembly. The enclosure includes a base that preferably includes integral side walls. The disk has a recording surface that has an annular landing zone. The head stack assembly includes a head supported to be moved radially relative to the recording surface and to be brought to rest at a position in the landing zone. Significantly, the head disk assembly also includes a unitary latch base member and a unitary pivot latch member. The unitary latch base member has a mounting portion for mounting the latch base member to the base, an arm extending parallel to the major interior-facing surface, an inner crash stop post including an engaging end, and a pivot post. The arm also includes a spring holding post. The unitary pivot latch member has a bore surrounding the pivot post to allow pivot motion of the pivot latch member.
