Abstract: A lubricant composition comprising an alkylated naphthalene component and a mineral oil component and which is essentially free of ammonia reactive components is described. In certain examples, the lubricant composition is food grade. The lubricant compositions are particularly well suited for use in ammonia refrigeration compressors and ammonia refrigerant transfer pumps. The mineral oil has no more than about 60 percent of paraffinic compounds by weight of the mineral oil. When used to lubricate ammonia refrigeration compressors, the lubricant composition has an ISO VG of 46 to 100. When used to lubricate ammonia refrigerant transfer pumps, the lubricant composition has an ISO VG of 22 to 46.

Abstract: Embodiments of the invention provide a food grade cleaning oil, such as one of synthetic or mineral oil origin, which can be used for the cleaning, flushing, and lubrication of compressors and vacuum pumps. The cleaner composition can include alkylated aromatics, such as naphthalenes. The cleaner composition can be compounded with additives including one or more of antioxidants, corrosion inhibitors, antiwear additives, metal passivators, and anti foam agents that are cleared for incidental food contact.

Abstract: Embodiments of the invention provide a food grade food grade lubricant, such as one of synthetic or mineral oil origin, which can be used for the lubrication of compressors and vacuum pumps. The lubricant composition can include a blend of alkylated aromatics, such as naphthalenes, and synthetic hydrocarbons comprised of polyalphaolefin fluids. The blend can be compounded with additives including one or more of antioxidants, corrosion inhibitors, antiwear additives, metal passivators, and anti foam agents that are cleared for incidental food contact.

Abstract: Embodiments of the invention provide a food grade lubricant, such as one of synthetic or mineral oil origin, which can be used for the lubrication of rotary screw compressors. The lubricant composition can include a blend of incidental food contact authorized ester or a distilled, acetylated monoglyceride. The lubricant composition can also include an incidental food contact authorized polyether polyol having an average molecular weight number greater than about 1500. The blend can be compounded with additives including one or more of antioxidants, corrosion inhibitors, metal passivators, and anti-foam agents that are cleared for incidental food contact.

Abstract: A work flow and communication system, particularly suited for an office environment, uses small, low-cost digital memo cards to convey a spoken message from a speaker to an associate. The speaker selects one of the cards and activates its record function and then speaks a message relevant to a particular business matter to record the message on the card. The card is then coupled via the attachment member to an office object that is associated with the business matter subject of the message. The office object is conveyed to the associate who can then play back the recorded message on the dictation card.
