Preferred embodiments allow a razor head to swivel and also to pivot about an axis normal to a central axis of the razor and normal to an imaginary axis defined by   the points of attachment of the razor to a razor head.          Preferred embodiments restrict the movement of the engagement arms to paths substantially parallel to a central longitudinal axis of the razor.   In this manner, a lateral component of razor head movement along an axis defined by engagement portions of the engagement arms is avoided.     According to another aspect, two biasing members are arranged in cooperative engagement to provide restoring forces of three different magnitudes to three different elements.

Inventor: MCCULLOUGH STEPHEN JOHN
IPC: D21F11/00
Filed: 1998-06-30
Abstract: Soft creped tissue that reduces fluid penetration can be produced by the indirect addition of chemical sizing agents to the tissue web by applying the chemical sizing agents to the surface of the Yankee dryer, such as by spraying. More specifically, the sizing agents can be included as part of the creping adhesive formulation, which is sprayed onto the surface of the Yankee dryer between the creping blade and the pressure roll. The sizing agents are subsequently transferred to the tissue sheet surface as the sheet is pressed against the Yankee dryer. The benefit of reduced fluid penetration is that hands remain drier during use.

Patent CA-2252325-A1 (CA)
Inventor: LEE CHARLES
IPC: H04L1/00
Filed: 1998-11-03
Abstract: A frame conveyed across the network is divided into a plurality of segments with an identical number of bits. All of the bits of a segment are received simultaneously, with each segment of the frame being received sequentially. Very often, the number of bits in the entire frame, will not be an integer multiple of the number of bits in the segment. Therefore the bits of the frame can be unevenly divided into the plurality of segments. The present invention detects the number of bits from the frame that are present in each of the segments, or at least the number of bits of the frame present in the last segment. An FCS function is used to create a segment FCS function which operates on all the bits of a segment at one time. The original FCS function is preferably an 8 bit function, which combines a present 8 bit word with the FCS calculated for previous 8 bit word in order to generate a new FCS for the present 8 bit word and all previous 8 bit words. By combining all the equations that would normally be required for all the 8 bit words in a segment, a segment FCS function is created which removes many redundant terms. Each segment is combined with a previous intermediate or segment FCS, to create a new intermediate FCS for the present segment and all previous segments. Subsegment FCS functions are also determined for each of all possible numbers of frame bits that are possible in a segment. The number of frame bits is detected and the corresponding subsegment FCS function is used.

Title: A method and system for address determination
Inventor: KENBEEK DENNIS L
IPC: G06F17/21
Filed: 1998-12-30
Abstract: The invention is a method and system for determining an address from a print buffer stream. The method begins with initializing an address detection and determination routine, and then directing a print buffer stream to be read by the address detection and determination routine. In reading the print stream data, the application tokenizes address data resident in the print stream before comparing the tokenized data with data tables wherein each of the data tables comprises address characteristics. In making the comparison of the tokenized address data, the method then determines whether or not the tokenized address data matches a format in one of the data tables. If a match is found, then the method applies a coding scheme to the matched data. The coding scheme being determined in accordance with the matched data's corresponding data table. Matched data is coded in accordance with the coding scheme to create a coded address. If a match can not be determined, then the tokenized data is placed in a memory of the addressing system for subsequent analysis or use. Each of the data tables within the system further comprise data establishing a definition of a particular address description based on carrier requirements. Address description is further defined by country specific address requirements; which in turn further comprise: linking files for use by an addressing software application to link an applicable data table with the application for the purpose of parsing address data based upon requirements resident in the data tables; barcoding requirements; and, postal zone requirements, if any, for postal coding.
