Abstract: METHOD AND APPARATUS FOR THE BILLING OF VALUE-ADDED             COMMUNICATION CALLS Abstract A call billing method and apparatus specifies, on a call-by-call basis, the calling charges incurred by a caller during a call to a sponsor-provided value-added service. The method provides the sponsor real time access to rate tables to specify call billing parameters needed to rate calls made to a sponsor number. A billingnumber is determined and validated and used to identify the party to receive a billing record for the call. A separate billing record is created for each call to the sponsor's number which includes sponsor-specified charges determined using the call billing parameters. Another feature enables the caller or called party to provide call billing parameters for billing and identification purposes.

Title: Drive sprocket for a chain saw
Inventor: O'NEEL TIMOTHY H
IPC: F16H7/06
Filed: 1991-04-16
Abstract: ABSTRACT OF THE DISCLOSURE      A sprocket including spaced rims with sprocket teeth confined between the rims.   The rims cooperatively define a configured periphery with link-supporting arc portions located at the teeth tips and flat sections extended between the arc portions.  As a side link approaches the sprocket, the leading lower corner (the toe of the leading footprint) passes over a flat portion to remain out of contact with the sprocket.  The following supporting arc portion rotates up into the notch formed in the bottom edge of the side link to support the side link as it travels around the sprocket.  The hammering effect of the leading lower corner of the side link impacting the sprocket of prior devices is avoided.

Title: Process for the conversion of fine superabsorbent polymers particles into larger particles
Inventor: WOODRUM GUY T
IPC: C08J3/24
Filed: 1991-05-30
Abstract: This invention is a method for converting fine particles of superabsorbent polymers into larger particles.      The invention is primarily directed to aqueous solution processes for preparing superabsorbent polymers. In such aqueous solution polymerization methods, the polymerization reaction product is a high viscosity gel which is dried and ground into particles. In this grinding step, a portion of the product is produced as undesired fine particles having poor absorbency and poor fabrication properties; i.e. they "gel block" and dust. According to the invention, fine superabsorbent polymer particles (up to about 3 parts) are mixed with the high viscosity reaction product gel (100 parts) containing about 20 parts by weight of superabsorbent polymer and water (5 parts per part of recycled particles) to form a mixture with improved rheological properties. The resulting mixture can be processed at a higher rate than a reaction product gel of equal solids content which results in a higher product yield and increased productivity.

Patent CA-2064803-A1 (CA)
Title: Cooling process and apparatus
Inventor: MORRIS GEORGE J
IPC: A23L3/30
Filed: 1990-08-07
Abstract: Material to be frozen is subjected to a cooling process which involves the efficient removal of latent heat of freezing. This can be achieved by subjecting the material being frozen to a greater rate of heat extraction when the latent heat is being given up than when the then solid material is being subsequently cooled further. Efficient removal of latent heat is also facilitated by inducing nucleation of the frozen liquid. Nucleation can be initiated acoustically and/or chemically. The invention, which has particular application in the frozen food industry and in the cryopreservation of biological material, allows shorter freezing times and/or improved quality or viability of the frozen product.
