Patent CA-2002015-C (CA)
Inventor: HALL JOSEPH L II
IPC: H03M7/42
Filed: 1989-11-01
Granted: 1994-12-27
Abstract: A technique for the masking of quantizing noise in the coding of audio signals is adapted to include geometric interpolation between the thresholds for a tone masking noise and for noise masking a tone, in order to reduce use of bit-rate capability where it is not necessary for transparent or high quality. The technique is usable with the types of channel coding known as "noiseless" or Huffman coding and with variable radix packing. The stereophonic embodiment eliminates redundanciesin the sum and difference signals, so that the stereo coding uses significantly less than twice the bit rate of the comparable monaural signal. The technique can be used both in transmission of signals and in recording for reproduction, particularly recording and reproduction of music. Compatibility with the ISDN transmission rates known as 1B, 2B and 3B rates has been achieved.

Filed: 1990-03-21
Granted: 1994-06-07
Abstract: Abstract of the Disclosure An illuminated sign is comprised of single piece molded plastic  front,  intermediate and rear frame members which are substantially coextensive with the width of the sign.   All of the characters are formed on the intermediate frame member and they fit into a front frame which serves not only as a support but as a means for masking those parts of the interme-diate frame which connect between characters, for ex-ample, and which should not be illuminated.

Title: Information recording and reproducing device
Inventor: FUJI HIROSHI
IPC: G11B11/10
Filed: 1990-07-20
Granted: 1996-10-01
Abstract: The present invention is an information recording and reproducing device, which records, erases and reproduces information on and from a memory device having pre-format sections, includes a pre-recorded area detection circuit for detecting a pre-recorded area having information predeterminately recorded and located on the memory device, and timing control circuits for providing timing control of an information recording, erasing or reproducing operation according to a pre-recorded area detecting signal released from the pre-recorded area detection circuit. Therefore, the timing of each recording, reproducing, or erasing operation is accurately determined. Additionally, the timing control may be performed according to both the pre-recorded area detecting signal of the present invention and the conventional synchronization detection signal. In case an error should occur in the synchronization detection signals, since the pre-recorded area detecting signal is released every time pre-recorded information for a sector mark or the like is reproduced, an accurate timing control without time lag is achieved according to the pre-recorded area detecting signals.

Patent CA-2038870-C (CA)
Inventor: ARTMAN THOMAS A
IPC: G21C21/04
Filed: 1991-03-22
Granted: 1994-03-22
Abstract: ABSTRACT OF THE INVENTION    A blending/loading system wherein an elongated cylinder or fuel rod is positioned on a turntable underneath a series of hoppers  containing  the  particulates  to  be  blended/loaded.          Separate transfer tubes from each hopper are aligned with the cylinder and are subsequently lowered into the cylinder.  Upon lowering, the cylinder is rotated and nozzles at the ends of the transfer tubes are activated to discharge, disperse and mix the stored particulates into the rotating cylinder.  As the cylinder fills up,  the transfer tubes are withdrawn from the rotating cylinder  until  the  desired  amount  of  fill  is  reached.          Afterwards, the nozzles block any additional flow from occurring as they are raised out of the cylinder.

Title: Production of low-chloride alkali metal phosphates
Inventor: NGUYEN KIM D
IPC: C05B7/00
Filed: 1991-08-26
Granted: 1996-06-18
Abstract: Potassium  phosphate  useful  as  a  low-chloride content fertilizer is prepared by reacting phosphoric acid,  commercial or technical grade, with fertilizer-grade potassium chloride (Muriate of Potash, 60-63% K2O) at a reaction temperature of about 130° to about 200°C and a mole ratio of phosphorus to potassium of at least about 1.3:1.  The vaporization of hydrogen chloride from the reaction mixture is effected by a novel technique combining  air followed  by  steam  stripping.    The reaction product is used to produce various types as well as grades of fertilizers.   The procedure may be used to form sodium phosphate in analogous manner from sodium  chloride,  which  then  may  be  converted  to trisodium phosphate or sodium tripolyphosphate.   The potassium  phosphate  may  be  converted  to  potassium pyrophosphate by neutralization with potassium hydroxide followed by calcination.

Granted: 2001-05-01
Abstract: A process for the surface treatment of a textile fiber through reacting a monomer or a prepolymer which can take place in a polymerisation process, thus forming a coating on the fiber surface. Polymerisation is induced by passing the fiber (1) in a reactor (13) through a reacting medium consisting in cold flowing plasma (14) and monomer (3) and/or prepolymer. The fiber is preferentially submitted to cold flowing plasma treatment prior to polymerisation so as to increase its tack properties.
