Abstract: An apparatus and method for making grain based baked products according to a predetermined ingredient recipe having a plurality of raw goods supply bins for raw materials. A processing unit selectively introduces predetermined amounts of the grain and the liquid/dry ingredients into a mixing chamber according to the recipe selected. The mixture produced is conveyed through proofing and baking steps. A customer interface permits selection of recipe, amount of product and time of delivery. The customer may place an order from a remote location using a phone or computer to have the baked grain based product produced at a desired time.

Abstract: An apparatus and method for making bread according to a predetermined ingredient recipe having a grain supply bin, a grinder for the grain, a dry ingredient supply, and a liquid ingredient supply. A processing unit selectively introduces predetermined amounts of the grain and the liquid/dry ingredients into a mixing chamber. The dough mixture produced is conveyed through proofing and baking steps.

Abstract: A thermal relay is disclosed which provides a bi-metal snap disc actuator system. The actuator system includes a central divider of material having relatively low thermal conductivity and a metallic disc cup mounted on each side of the central divider. A bi-metal snap disc is located in each disc cup and a separate heater is provided to respectively heat the discs. The discs are mounted so that they tend to move toward each other at normal environmental temperatures and a bumper is interposed between the discs to cause them to move in with snap action in the unison. The actuator operates two switches. In one embodiment, one switch is normally closed and the other switch is normally open. In another embodiment, both switches are normally open.

Abstract: A condition-sensing switching device is disclosed having a plurality of active switch elements which are not symmetrical with the line of action of the condition-sensing actuator. A dummy element is provided to establish symmetry and produce a balanced condition on the switch actuator. The switch elements and dummy element are arranged so that no resilient forces are applied to the actuator during a portion of the actuator movement and the resilient forces on each element simultaneously are applied in a balanced manner during actuator movement to ensure that the forces on the actuator are balanced in all positions of the actuator. An adjusting screw is provided to adjust the force of one spring to ensure that absolute balance is achieved.

Abstract: A ventilation fan which is adapted to be ceiling mounted such as in an attic space above a room ceiling. The fan is arranged to pass upwardly through the space between the ceiling joists in a compact arrangement and to be extended once it is disposed above the room ceiling to define an operating configuration. In the operating configuration, the air moving apparatus is swung outwardly from the housing of the fan on a pivotally mounted wall portion thereof. The fan redirects the upwardly flowing air from the subjacent room at a substantial angle to the vertical in the attic space for improved ventilation functioning.

Abstract: A fluid flow device having a biased closure structure for selectively closing an opening in a flow conducting structure. The closure includes a pair of closure members pivoted relative to a transverse axis of the opening and biased to the closed position by a spring which is maintained spaced from the closure members in the closed position thereof. The spring has a midportion which is brought into engagement with the closure members as an incident of the movement thereof to and beyond a preselected position intermediate the closed and fully opened positions of the closure members. The spring acts to resiliently bias the closure members toward the closed position as result of the spring tension between the closed position and the intermediate position and the abutment of the midportion of the spring with the closure members at and beyond the intermediate position permits the closure members to be swung toward the fully open position with a decreased force.

Abstract: The method of autogenously bonding a nonwoven web made from polyamide filaments wherein the filaments contain 0.1 to 20 weight percent of an activating agent and sufficient moisture that the molar ratio of water to activating agent in the filaments is above the bonding limit, wherein the web is heated sufficiently to drive off enough water to reduce the molar ratio of water to agent to a value below the bonding limit and pressed to autogenously bond the filaments in the web. After pressing, the activating agent is desorbed from the web.

Abstract: The method of pattern bonding nonwoven webs made from polyamide filaments wherein the web is exposed in a first treatment zone to a gaseous mixture of an activating agent and water and is then exposed in a second treatment zone to a wet atmosphere to allow the web to absorb enough additional moisture so that the web becomes essentially unbondable when pressed at room temperature. The web is then passed between a pair of rolls, at least one of which is embossed or engraved and heated to a sufficient temperature to autogenously bond discrete portions of the web while leaving the remainder of the web essentially unbonded. The high molar ratio of water to activating agent in the outer portions of the filaments in the web will prevent bonding of the web in those areas not contacted by the embossed roll, so that the web will have a high tenacity plus good drape and hand characteristics.

Abstract: A control system for a central air conditioner. The air conditioner includes an outdoor condensing unit including a refrigerant compressor, an indoor evaporator unit, an indoor thermostat responsive to the indoor temperature for controlling the air conditioner, and a control system for protecting the air conditioner and indicating to the user certain malfunctions in the air conditioner should they occur. The malfunction indication may be by means of signal lights and a manually operable reset control is provided permitting the user to reset the control system. The malfunction indicator and reset control are disposed adjacent the thermostat for facilitated determination of the system operating condition. The control system includes an improved control portion for starting of the compressor motor which is arranged to prevent operation of the system in the event of a low power supply voltage condition.
