| 20090221744 | PROCESS FOR PREPARING A HIGH-COHESION PSA - A process is presented for the preparation of a high-cohesion non-thermoplastic pressure-sensitive adhesive (PSA) on the basis of elastomers, in which neither a solvent nor thermoplastic additives are used and yet thermal breakdown during compounding is kept low. This is achieved through the addition of a vaporizable process agent which is introduced into the adhesive after the constituents have been premixed and which undergoes flash vaporization therein, thereby quenching the adhesive. Furthermore, the use of water to cool the adhesive is proposed, and the high-cohesion PSA thus produced, and also a pressure-sensitive adhesive tape with an adhesive of this kind, are presented. | 09-03-2009 |
| 20110100551 | Adhesive assembly tape for interior finishing - Adhesive assembly tape for interior finishing, comprising a carrier and an adhesive coated from the melt to at least one side of said carrier, | 05-05-2011 |
| 20110256395 | Pressure-sensitive adhesives based on natural rubber and polyacrylates - A pressure-sensitive adhesive consisting of a homogeneous mixture of at least one natural rubber component and at least one polyacrylate component displays significantly improved properties in cohesion and aging and weathering resistance compared to the individual components. Particularly good properties are achieved when the adhesive contains x% by weight of at least one natural rubber component, y% by weight of at least one polyacrylate component, v% by weight of at least one adhesive resin component and w% by weight of additives, where 10≦×x≦80, 10≦y<95, 0≦v≦50, 0≦w≦10 and x+y+v+w=100. A single- or double-sided adhesive tape consisting of at least one support and at least one layer of such a pressure-sensitive adhesive therefore likewise has good cohesion and aging resistance properties. | 10-20-2011 |

| 20110168793 | ECONOMIZER CONTROL - The present disclosure provides a method for operating an HVAC system for conditioning air of an inside space. The HVAC system has an economizer configured to control the intake of outside air into an HVAC air stream of the HVAC system. The method includes determining at least two parameters of the air of the inside space, where the at least two parameters are selected from a set of parameters from which an inside air dry bulb temperature, an inside air dew point, an inside air relative humidity, and an inside air enthalpy can be determined, either directly or indirectly. The method also includes determining at least two parameters of the outside air, where the at least two parameters being selected from a set of parameters from which an outside air dry bulb temperature, an outside air dew point, and an outside air enthalpy can be determined, either directly or indirectly. Based on one or more of the inside air dry bulb temperature, the inside air dew point, the inside air relative humidity, and the inside air enthalpy, a determination is made of whether dehumidification of the inside space is needed, and if dehumidification is not needed, the economizer is commanded to increase the intake of outside air into the HVAC air stream if the outside air dry bulb temperature is less than a dry bulb temperature reference, and if the outside air enthalpy is less than an enthalpy reference. If, alternatively, dehumidification is needed, the economizer is commanded to increase the intake of outside air into the HVAC air stream if the outside air enthalpy is less than the enthalpy reference, and if the outside air dew point is less than a dew point reference. | 07-14-2011 |
| 20110172831 | ECONOMIZER CONTROL - The present disclosure provides a method for controlling an economizer of an HVAC system. The economizer has an outside air stream of incoming outside air, a return air stream of return air, and a mixed air stream of mixed incoming outside air and return air that is provided to the cooling unit of the HVAC system. The economizer also includes one or more controllable dampers for controlling a mixing ratio of incoming outside air to return air in the mixed air stream. The control method includes positioning the one or more controllable dampers in first and second configurations such that the mixed air stream has first and second mixing ratios of incoming outside air to return air in the mixed air stream. The method also includes recording first and second measures related to the temperature of the mixed air stream when the dampers are in each of the first and second configurations. First and second measures related to other parameters of the mixed air stream may be recorded as well. Based on the recorded first and second measures related to the temperature of the mixed air stream and possibly other recorded measures related to mixed air stream parameters, the method determines whether and/or how much of the incoming outside air to admit into the economizer via the one or more controllable dampers during subsequent operation of the HVAC system. | 07-14-2011 |
| 20110264274 | DEMAND CONTROL VENTILATION WITH FAN SPEED CONTROL - A method and system for operating a demand control ventilation system with a multi-speed fan is disclosed. The control system may modulate the fan speed of a multi-speed fan and/or the position of a ventilation damper in order to achieve desired ventilation levels for a building. | 10-27-2011 |
| 20110264275 | DEMAND CONTROL VENTILATION SYSTEM WITH COMMISSIONING AND CHECKOUT SEQUENCE CONTROL - The disclosure relates to a Demand Control Ventilation (DCV) and/or Economizer system that is capable of drawing outside air into an HVAC air stream. In some instances, the DCV and/or Economizer system may be configured to help perform one or more system checks to help verify that the system is functioning properly. In some instances, the DCV and/or Economizer system may provide some level of manual control over certain hardware (e.g. dampers) to help commission the system. The DCV and/or Economizer system may store one or more settings and or parameters used during the commissioning process (either in the factory or in the field), so that these settings and/or parameters may be later accessed to verify that the DCV and/or Economizer system was commissioned and commissioned properly. | 10-27-2011 |
| 20110264280 | AUTOMATIC CALIBRATION OF A DEMAND CONTROL VENTILATION SYSTEM - Methods and systems for automatically calibrating one or more damper positions of a demand control ventilation system are disclosed. In one illustrative embodiment, a demand control ventilation system includes a damper for controlling a flow of outside air into a building. A controller may be programmed to automatically execute a calibration algorithm from time to time to calibrate one or more calibration damper positions such that a predetermined flow of outside air is drawn through the damper and into the building at each of the one or more calibration damper positions. This calibration can, in some instances, help increase the efficiency and/or utility of the demand control ventilation system. | 10-27-2011 |
| 20120079425 | ECONOMIZER CONTROLLER PLUG AND PLAY SYSTEM RECOGNITION WITH AUTOMATIC USER INTERFACE POPULATION - An economizer controller system having a plug and play recognition approach with an automatic user interface population mechanism. A check may be made for sensors connected to the controller. The control type of the sensors may be determined. The menu structure may be repopulated based on the control type. The user interface may then be updated. This approach may be repeated as needed. | 03-29-2012 |
