Abstract: A mobile security system used to manage pedestrian activities from a perimeter of a venue to a point of entry to the venue and into the venue. The mobile security system includes a portable hub unit configured to be located at the point of entry to the venue. The hub unit includes at least one touchless screening lane that defines a path through the hub unit. The hub unit also includes at least one external screening device that screens for security threats external to the hub unit, and a plurality of lane screening devices associated with the at least one screening lane to screen for security threats within the at least one screening lane. The hub unit further includes a processing unit configured to receive data and characterize the received data as being indicative of one or more security threats or a non-security threat.

Abstract: A portable, vertical tower fan capable of generating a vertically oriented exhaust air stream that conforms better to a user at an elevation above a support surface. The device includes an vertically elongated housing, an air blower assembly located within the elongated housing and a base provides a space saving design.

Abstract: A portable electrical blower assembly is provided. The portable electrical blower assembly has a pair of wall members; a motor control assembly coupled to a surface of one of the wall members, the motor control assembly including a motor control housing; a motor adjacent the motor control assembly and coupled thereto; and an air director disposed between the pair of wall members, the air director being rotatable with respect to the pair of wall members and the motor.

Abstract: An aqueous composition useful for the protection of actinic light-exposed presensitized lithographic printing plates. The composition comprises an effective amount of (a) an ammonium, sodium, potassium or lithium salt of a strong organic acid, and (b) an ammonium, sodium, potassium or lithium salt of an anionic surfactant which contains functionalities of the salt of a strong organic acid and the salt of a weak organic acid, and (c) an ammonium, sodium, potassium or lithium salt of a weak organic acid. The composition is applied to the surface of the plates after they have been developed, but before they have been baked, thereby preventing surface contamination that would otherwise occur from the heat treatment.
