Title: Abrasive filament honing tool and method of making and using same
Inventor: SCHEIDER ALFRED F
IPC: B24D13/10
Filed: 1992-08-17
Abstract: A honing tool characterized by an elongated rectangular cup element or holder having a bottom interior surface, a bundle of closely packed relatively short discrete generally parallel filaments secured in the holder, and a thin layer of instant adhesive securing substantially all of the filaments at one end face of the bundle to the bottom interior surface of the holder. To make such a honing tool, a measured bundle of uniformly closely packed nonwoven, generally parallel discrete filaments is formed. A holder is supported and a measured amount of liquid adhesive is placed in the bottom interior of the holder so that a thin layer of such adhesive completely covers the bottom of the interior of the holder. The bundle is then promptly driven into the holder so that all of the filaments at one end of the bundle are in contact with the adhesive prior to the curing of the adhesive. The adhesive is then cured whereby the one end face of the bundle is secured to the bottom interior of the holder.
Patent CA-2078021-A1 (CA)
Inventor: MCKAVANAGH THOMAS P
IPC: F16K3/02
Filed: 1992-09-11
Abstract: A sealing sleeve for a gate valve is disclosed which is designed to respond to movements of the gate of the valve in a particular manner.  The seal undergoes an axial compressive type movement as the gate is moved between opposed sealing sleeves and this causes a predetermined radially inward buckling of an intermediate wall section of the sealing sleeve.  This predetermined buckling creates a spring bias in the sleeve, urging the sleeve to return to the original, less stressed condition. Preferably, the sleeve is of a composite structure and a particular component of the intermediate wall section creates this spring bias.  This structure has improved operating characteristics and accommodates a wider range of resilient materials to be used for the sealing sleeve.

Title: Open coil heater for efficient transport
Inventor: HOWARD KEITH H
IPC: F24H9/18
Filed: 1992-09-25
Abstract: An electric heater includes an electric heating coil that extends above the sidewalls of an air flow channel. The coil is formed in sections that extend transversely to the channel and are spaced by the width of a coil section to allow two heaters to be arranged face to face for shipping. This arrangement is very efficient because one of the heaters provides protection to the coil of the other of the heaters to reduce packaging costs.

Title: System for encoding and decoding of convoltionally encoded data
Inventor: BITZER DONALD L
IPC: H03M13/23
Filed: 1993-02-18
Abstract: ABSTRACT            A convolutional encoding/decoding system encodes a data bit stream into n bit parity sets from k bit data bit sets, using code words of length L.  The system is dependent upon the finding that unique data to parity tables can be generated where both data and parity bit blocks are w bits in length. The value of w = n(L-k)/(n-k).  An encoded parity bit stream is subjected to Exclusive OR operation through  a  connection  mask  or  masks  that  are dependent  upon  the  encoding  code  words.   The Exclusive OR operation generates syndrome symbols indicative of the presence of errors in the parity bit stream and which are employed to address a correction table.   Parity  correction  values  are derived from the correction table and are used to revise  the  parity  bit  stream,  which  is  then decoded, using a parity to data table.  A number of parity correction procedures are disclosed.
