Patent CA-2006814-C (CA)
Title: The utilization of polyester in place of lead for use as a sheathing material for curing long length hose
Inventor: WELLS HOYT MELLOR
IPC: B29C48/09
Filed: 1990-01-02
Granted: 1999-09-07
Abstract: A method of vulcanizing a tubular article by extruding a sheath of unoriented polyethylene terephthalate about the article followed by quenching the sheath to an amorphous state. The sheathed article is then subjected to vulcanizing conditions in order to convert the sheath from the low density amorphous state to the higher density crystalline state, thus compressing the article to effect a smooth finish.

Title: Anti-pickpocket alarm
Inventor: YANNOTTI JULIAN J
IPC: G08B13/14
Filed: 1990-02-13
Granted: 1994-09-20
Abstract: ABSTRACT An audible alarm device to alert a person that his wallet or the like has been stolen from his person, the alarm being con-cealed within the wallet and tethered to the person carrying it. The wallet alarm sounds when the wallet is removed far enough to tighten the tether, which action disconnects it from the wallet and activates the alarm. In another embodiment, a second alarm concealed on the person or in a handbag is also activated simul-taneously when the tether is pulled, alerting the wearer as well as the thief.

Title: Adaptive phase lock loop system
Inventor: YATSUZUKA YOHTARO
IPC: H04L27/227
Filed: 1990-09-13
Granted: 1994-04-05
Abstract: A phase lock loop for a digital input signal has a phase detector, a loop filter, a digital voltage controlled oscillator (VCO), an initial phase difference calculator, a center frequency difference calculator and an input buffer memory.  In an initial training mode prepared in the PLL operation, an optimum initial phase and an optimum center frequency of the VCO to complete a lock-in state is searched for the input signal stored in the buffer memory.  By estimating the initial phase difference and the center frequency different between the input signal and the VCO output with repetitive kick-offs in calculators, optimum values mentioned above are obtained.  In a normal operation mode as a second mode in which the PLL operates normally as a conventional PLL, a phase lock operation between the VCO output as the reference signal and the input signal in the buffer memory is carried out after the PLL is kicked off with the optimum initial phase and the optimum center frequency determined in the initial training mode.

Title: Process for the manufacture of a thermostructural composite material having a carbon interphase between its reinforcement fibers and its matrix
Inventor: HERAUD LOUIS
IPC: C04B35/80
Filed: 1991-03-22
Granted: 1997-09-16
Abstract: The  thermostructural composite material is  produced  by forming  a fibrous preform made from refractory fibers coated  with a  sizing agent. The preform is densified by a  refractory  matrix, in  particular  ceramic,  while a  carbon  interphase  is  provided between  the  fibers and the matrix. The fibrous  preform  is  made from refractory fibers coated with a sizing agent of the type  that leaves  behind  a carbon residue upon  thermal  deccmposition. The carbon  interphase  is produced by the thermal degradation  of  the sizing agent, occurring for example after the preform is made.  The sizing  agent  is  chosen among  phenolic,  acrylic  and  cellulose resins, and in particular carboxymethylcellulose.

Title: Foamable aerosol preparation
Inventor: NAKAGAWA AKIRA
IPC: A61Q7/00
Filed: 1990-07-23
Granted: 1995-06-20
Abstract: A foamable aerosol preparation for use as the base of cosmetics, quasi drugs, drugs, and so forth, which comprises 0.1 to 5 w/v% of a surfactant, 0.05 to 10 w/v% of a lower alcohol and/or a glycol, 3 to 25 w/v% of water, and 60 to 95 w/v% of n-butane gas.  Despite of the use of n-butane gas as the propellant, this preparation foams very well and is excellent in cracking sound when applied to skin.          Furthermore it is particularly useful from the viewpoint of environmental protection, because it is free from the problem of the depletion of the ozonosphere by virtue of the use of a liquefied petroleum gas as the propellant instead of fluorocarbon gas heretofore used.

The pallet wrap has eyelets which permit fastening of the wrap to a pallet. The pallet includes at least two main stringers made of a U-shaped metal section, a load supporting platform supported by the main stringers and at least two legs per main stringer which are made of a metal pipe to support the main stringers at a fixed distance from a supporting surface. The pallet wrap and pallet combination more reliably retains a stack of articles and better withstands damage during handling and transport.

Title: Motorized pulley with internal mounts
Inventor: HALL DAVID V
IPC: F16H1/46
Filed: 1992-06-02
Granted: 1994-04-26
Abstract: ABSTRACT OF DISCLOSURE A drive pulley assembly is disclosed for a conveyor belt assembly which permits a reduction in the overall size of the conveyor assembly without any reduction in the size or width of the conveyor belt. The overall width of the conveyor assembly is reduced by providing recessed end cavities in the ends of the drive pulley to accommodate the mounting brackets for the pulley. In accordance with the present invention, the mounting brackets are secured to the inside of respective frame members and extend therefrom into the recessed end cavities of the drive pulley such that substantially the entirety of the mounting bracket lies within the drive pulley. Because the mounting brackets are contained substantially within the confines of the drive pulley, the drive pulley assembly of the present invention requires less space than conventional conveyor assemblies in which the mounts are disposed beyond the ends of the drive pulley.

Title: Radio pager with variable gain setting controlled according to presence and absence of sync codes
Inventor: TSUNODA KAZUYUKI
IPC: H04W56/00
Filed: 1992-06-24
Granted: 1996-07-02
Abstract: A radio pager has a variable gain adjustable to high setting for normal reception or low setting at which the strength of intermodulation products is reduced in relation to the strength of a desired signal. A sync code contained in a received signal is detected to establish synchronization and a sync-absence signal is generated if it is not detected during a time interval in which it is expected to occur. The pager is initially switched to the high gain setting. In response to a first generation of the sync-absence signal, the pager recognizes that the desired signal is severely affected by intermodulation products and switches to the low gain setting so that the signal-to-noise ratio of the desired signal is improved. In response to a second generation of the sync-absence signal, the pager recognizes that its amplification gain is not sufficient and switches to the high gain setting to resume normal reception.

Title: Construction block with guiding system for walls
Inventor: RODRIGUE JACQUES
IPC: E04C1/39
Filed: 1992-07-10
Granted: 1995-01-10
Abstract: Construction block with guiding system for walls ABSTRACT     The present invention relates to a block for the construction of a wall which is made of a plurality of similar blocks disposed one upon the other in horizontal courses in end to end relation and to overlap the adjacent ends of the blocks forming the next below course of blocks. The block comprises a top, a bottom, a front, a rear and side faces. The bottom face of a block further includes guiding means extending from same. The bottom face of a block of a subsequent course of blocks also has a complementary shape with respect to the top face of a block from the next below course of blocks so that a relative movement, such as a rotation, is possible with respect to an axis generally perpendicular to the top and bottom faces. Upon the erection of the wall, the guiding means of a specified block of the subsequent course of blocks rests on the rear face of adjacent blocks of the next below course of blocks and the guiding means are used to guide such relative movement of each block of the subsequent course of blocks with respect to the next below course of blocks in order to create a wall which, when viewed from above, can be flat, rounded or a combination of both and this, without the necessity of providing different types of blocks for different types of applications. In addition, the erection of the wall does not necessitate any special tooling. Dueto the guiding means, each overlying horizontal course is automatically set back from the next below horizontal course.

Each end wall has several layers, two of which are main layers.  A tear strip panel extension (46, 47) is attached to the main layers below the tear strip.  An ear (48, 49), which is attached to the tear strip panel extension and top wall, prevents the granular material from migrating between the tear strip panel extension and main panels.
