Abstract: A touchless car wash composition, that can be made from a concentrate and diluted to use concentration using commonly available service water can comprise an ether amine or diamine in particular a fatty ether amine or diamine. The novel compositions are typically free of hydrocarbon solvents and silicone materials that are common in prior art compositions. The compositions are used in touchless car wash processes in which the materials are sprayed in the form of an aqueous dilute solution to remove soil from the vehicle surface. The aqueous compositions are self removing and very small amounts of the aqueous solutions remain to create water spotting on cleaned vehicle surfaces. The novel compositions of the invention can also contain a variety of other ingredients in a fully formulated system. Such ingredients include rapid dewatering of painted surfaces, improved cleanliness of glass and painted surfaces. A substantial reduction of water spotting and concentrates stability. When used in systems using the direct contact between a brush, the friction between the brush and the vehicle surface is substantially reduced.

Abstract: A  horizontal  plane  frictional  coefficient  testing apparatus and methods are provided which include a substantially horizontal planar platen having two spaced, parallel movable rails.          The rails are actuated by a motor adapted for reversibly raising and  lowering  the  rails  relative  to the  platen.    A  sled  of predetermined weight is also provided having a central body and two pairs of outwardly extending axles, with each pair of axles being of equal length and formed with a wheel at the end thereof.  The wheels of the sled are formed for engagement with the rails and engagement of the wheels with the rails locates the sled generally parallel to the rails.  In operation, a sample of sheet material is fixed to the sled and the sled is placed on the rails, with the rails being in a raised position.   Subsequently, the rails are lowered to gently place the sled onto the platen or a test medium fixed to the platen.  A drive arm is included with the apparatus for pulling the sled relative to the platen at various rates of translation.  A load sensor mounted on the drive arm measures in real time the force applied to the sled during the course of the test.  The data collected by the load sensor is transmitted to a central  processing  unit  which  calculates  the  coefficients  of friction.  A timing mechanism may be provided to monitor the dwell time of the sled on the platen prior to initiation of the tests.          Also, a semi-rigid coupling may be used to connect the sled to the drive arm.

Abstract: A single document page with multiple different variable indicia from at leas t two discrete sources is produced using a computer control and an imaging system (such as a selective flexographic system with ion deposition or ink jet stations), variable database streams and variable data streams from at least two discrete sources are fed to the same computer control, which is then used to control the imaging system to merge the variable database streams and variable data streams from at least two discrete sources so that they may be imaged on the same document page. Paper is fed to the imaging system, and using the imaging system the same document page is imaged with variable database indicia from the multiple discrete sources. Three, or even more, discrete sources can be utilized, and each discrete source may also have a distinct form structure so that the variable data indicia an d variable database indicia are each placed in their own distinct form structure. The variable database streams may include company name and logo data, coupon data, direct marketing messages, and/or images, or the like, while the variable data streams includes alphanumeric characters which convey account and/or billing information. All of the indicia may be imaged on the same face of a single sheet (e.g. having a maximum length of about 12 inches and a maximum width of about 9 inches), and imagining may take place on a web which is then cut into individual single pages.

Title: System and method for providing enhanced services for a telecommunication call
Inventor: CHRISTIE JOSEPH M
IPC: H04Q3/00
Filed: 1997-11-10
Granted: 2007-08-07
Abstract: A system and method provide enhanced services for a call that is transported from a communication device (106) through an asynchronous transfer mode system. The call has user communications (124) in asynchronous transfer mode cells and call signaling (116).  A signaling processor (110) receives the call signaling and processes the call signaling to determine a connection to a service platform (112). The signaling processor transports a processor control message (120) designating the selected connection. An asynchronous transfer mode interworking unit (114) receives the user communication from the communication device and the processor control message from the signaling processor. The asynchronous transfer mode interworking unit converts the user communications from the asynchronous transfer mode cells to a format compatible with the service platform and dynamically transports the user communications to the service platform in real time. The service platform processes the user communications.

Title: Duct cleaning device
Inventor: GOODMAN FRANK
IPC: B08B9/04
Filed: 1999-10-15
Granted: 2002-06-11
Abstract: A duct cleaning device including a flexible conduit having a first end and a second end with inlets at first end and outlets at second end to allow air to circulate within the conduit. A whipper located at first end is rotated by a drive shaft, housed within the conduit, and powered by an air-activated drive means located near to the whipper at first end of the conduit. A stationary circular brush is also located around the conduit near its first end. In operation, the air-activated drive means is activated by air passing though the conduit preferably when a vacuum is applied. The vacuum is created a pressure reducing air pump to which the second end of the conduit is attached. The device may be mounted with a dolly, and displaced within a duct using rods attached to the dolly. The loosened debris generated by the action of the whipper and brush on the internal surfaces of the duct are aspirated through the inlets and into the conduit by the vacuum.
