Abstract: An improved system for filtering particulate matter from a liquid in a brewing pot. The improvement includes a filter assembly positioned about a drain tube. The filter assembly has a screen member surrounded by a shield member. The shield member is positioned between the drain tube and the particulate matter separated from the liquid. The bulk of the liquid, located in a top portion of a reservoir bypasses the screen member and drains through a drain reservoir and the drain tube. After removing the shield member, the remainder of the liquid drains through the screen member or filter and into the drain reservoir preventing the particulate matter from being carried through to a fermentor.

Abstract: An improved temperature measurement device to aid in the brewing of beer. The invention provides a special dial face with common brewing process temperature ranges and ideal process target temperatures, guiding the brewer through the brewing process. In addition, the invention provides an improved weldless installation means that is rigid and not prone to leaking.

Abstract: An improved brewing stand enables ease of assembly, repeated assembly and disassembly allowing the brewing stand to be transported from one location to another location. The modular assembly enables a plurality of tiers to be positioned in an infinite number of vertical positions between a bottom of a mast and a top of the mast. A plurality of legs are removably attached to the bottom of the mast. Leveling devices are provided to maintain the mast in a vertical position.

Abstract: An improved temperature measuring device for the in-line temperature measurement of fluids which does not require intimate contact of the fluid with the temperature sensing element. In addition, the invention contains no internal cavities or crevices making it very advantageous for food and chemical usage. In the preferred embodiment, a liquid crystal temperature sensing element is affixed to a thermally conductive fluid carrying member. Each end of this fluid carrying member having fittings which enables the thermometer assembly to be quickly removed for cleaning and sanitizing.

Abstract: An overflow prevention mechanism for use in association with liquid transfer systems of the type including an electrically controllable flow control device such as a pump connected between a source of liquid and a liquid tank, the mechanism including a backup liquid level sensor and a shunt trip breaker or other normally-closed switching device. The backup liquid level sensor senses if the level of liquid within the tank reaches an extreme high level. When the liquid level within the tank reaches the extreme high level the backup liquid level sensor produces an output indicative of the liquid having reached such extreme high level. The shunt trip breaker is connected between the source of electrical energy and the flow control device.

Abstract: An exhaust system for an internal combustion engine includes an enclosure with a top wall having an opening. An exhaust pipe includes an exhaust outlet and an outlet flange which is attached to the pipe at the exhaust outlet. The outlet flange is disposed adjacent to the opening in the enclosure. An exhaust muffler includes an exhaust inlet and an inlet flange which is attached to the muffler at the exhaust inlet. A rain skirt is interposed between and attached to each of the outlet flange of the exhaust pipe and the inlet flange of the exhaust muffler. The rain skirt has a hole therein allowing fluid communication between the exhaust pipe and the exhaust muffler. The rain skirt extends outwardly from the outlet flange and prevents water from entering into the enclosure through the opening.

Abstract: A temperature control system includes an enclosure having a plurality of adjoining walls. An inlet louver assembly is disposed within one of the walls, and includes a plurality of inlet louvers. An outlet louver assembly is disposed within an other of the walls, and includes a plurality of movable outlet louvers. An actuator is coupled with the outlet louver assembly for moving the plurality of outlet louvers. An internal combustion engine is disposed within the enclosure. An ambient air temperature sensor is disposed within the enclosure for sensing an ambient air temperature within the enclosure and providing an output signal. An engine temperature sensor is coupled with the engine for sensing a temperature within the engine and providing an output signal. An electrical processing circuit is coupled with each of the ambient air temperature sensor, the engine temperature sensor and the actuator.

Abstract: A sound attenuator for an enclosure, in particular, an apparatus for attenuating the sound at the openings which allow air to enter and exit an internal combustion engine enclosure with minimal pressure loss. The attenuator comprises a combination of passive sound absorptive louvers place in series with a plurality of reactive Helmholtz resonator units mounted in parallel rows in the open area between each pair of louver. The Helmholtz resonators being tuned to attenuate a single or multiple low frequency noise spikes. The attenuator providing improved sound attenuation and requiring substantially less volume than a typically used absduct type silencer.
