Patent CA-2092452-A1 (CA)
Title: Adaptive signal modulation system
Inventor: CHETHIK FRANK
IPC: H04L27/36
Filed: 1993-03-25
Abstract: Digital signals are converted to phase and amplitude altered, periodic, analog signals and emplaced on an output link. The system is adaptive and includes a plurality of simple quadrature phase shift keying modulators, each modulator having a plurality of controlling digital inputs, the states of which determine which of a plurality of phase displaced signals will be outputted. A local oscillator provides a periodic sinusoidal signal to each QPSK modulator. Summing circuits combine the outputs of the modulators so as to produce a constellation of phase and amplitude-displaced output sinusoidal signals. A processor/mapper combination enables conversion of a first set of digital inputs to a different set of digital outputs in accordance with a control input. Thus, the processor enables the alteration of the constellation of outputs in accordance with a control input, which may be indicative of the condition of a transmission facility.

Abstract: GOLF TEE                 ABSTRACT OF THE DISCLOSURE           A two-piece, realignable golf tee comprises a lower,  integrally molded plastic piece comprising a ground  spike,  a central  flange,  a  relatively thin, flexible retainer shaft extending away from the ground spike  in  substantially  parallel  relation,  and  an enlargement adjacent the outer end of the retainer shaft.          An upper, integrally molded plastic piece comprises a sleeve slidably positioned about the flexible retainer shaft.  The sleeve defines a bore having a constricted portion adjacent a first sleeve end that faces the ground spike to engage the enlargement, to substantially limit movement of the sleeve away from the spike and out of engagement with the retainer shaft.  The central flange is proportioned to serve as a seat for the first sleeve end, with the end of the sleeve opposed to the first end being proportioned to serve as a seat for a golf ball.          The  two,  integrally  molded  plastic  pieces  may  be assembled in snap-fit relation.

Title: Prevention of discoloration of cementitious and masonry construction products
Inventor: NEEDHAM JAMES K
IPC: B05D7/24
Filed: 1993-05-26
Abstract: PREVENTION OF DISCOLORATION ON CEMENTITIOUS      AND MASONRY CONSTRUCTION PRODUCTS            Abstract the Disclosure An economical method of protecting masonry and cementitious construction products, such as portland cement-wood fiber composite roofing shakes (10), prevents the release of by-products which deposit on and cause discoloration of nearby construction products.  A protective layer is applied, for example, to only a selected portion (28) of a back surface (14) of a roofing product.  The front surface (12) of the roofing product is typically protected by paint, and portions of the rear surface are protected by other overlapping roofing products.  The protective layer prevents efflorescence by sealing the surface and binds any surface layer imperfections to the bulk of the roofing product.

Title: Computer workstation using different video data formats
Inventor: WILSON DAVID A G
IPC: H04N1/00
Filed: 1993-06-23
Abstract: A computer workstation runs an application 10 to participate in a video conference.  The workstation contains  a video adapter card 18 which converts a video signal produced by a camera 20 into a hardware specific  format.  Likewise,  the video adapter card can also be used to display incoming video signals that are in the same hardware specific format. The  workstation  also contains  software  support  modules (SSM).  On the capture side,  the SSM 16 provides a video signal in bit map form for transmission to terminals in the conference which  do  not  have  compatible  video  hardware. Correspondingly, on the display side the SSM 34 receives and displays incoming video signals in bit map form from other workstations which likewise do not have compatible hardware.

Title: Heat-exchanger for arrangement behind the combustion chamber of a heating boiler
Inventor: VIESSMANN HANS
IPC: F24H1/28
Filed: 1993-06-23
Abstract: ABSTRACT The invention is concerned with a heat exchanger for arrangement behind the combustion chamber of a heating boiler. The heat exchanger comprises water-carrying and gas-carrying interior chambers separated from one another by walls extending in parallel and being helically coiled about a filling member and sealed against one another by cranked edges. In order to so form a preferred form of embodiment of a heat-exchanger of this type that the participating components, considering the coiling process, can be dimensioned thin and nevertheless insure a pressure-stable final condition, thereby foregoing separate spacers actually not forming part of the heat-exchanger and thereby preventing or substantially preventing during coiling into a helix the edges to be joined by welding from forming wave-type warpings and the wall faces from deforming, the heat-exchanger according to the invention is designed such that the wall which relative to the coil axis is the inner wall, at the top and at the bottom, includes externally cranked edges of a width at best corresponding to the width of the water-carrying interior and the outer wall includes inwardly cranked edges of a width corresponding, at best, to half the width (B), which edges overlap the edges of the inner wall or are in alignment therewith and are connected thereto in fluid-tight manner. Corrugated structures of both walls protruding into the gas-carrying interior open at the inlet and outlet sides, are arranged at a distance (D) from the edges in the walls extending substantially in parallel to the coil axis in a mutally supporting manner. The water-carrying interior is sealed at both ends of the helix except for the forward and return connection openings.

Title: Apparatus and Method for Treatment of Waste Water Sludge
Inventor: KEW ALAN S
IPC: C02F3/12
Filed: 1993-02-17
Abstract: A method and apparatus for treating liquid waste water sludge after its generation and separation from the waste liquid involves propelling a plurality of separate streams of sludge via, for instance, a rotor (37) and then forcibly impacting sludge particles and microbial cells contained in the propelled streams of sludge against a contact surface such as a stator (59), for recirculation of sludge along toroidal paths (62) and (64), to thereby fragment the particles into smaller sized particles and break apart the organic cells. As a result of such a fragmentation process, water located in the pores of the sludge particles is released, thereby enhancing a subsequent dewatering process performed on the sludge. The destruction of the cells permits a subsequent solids digestion process to work more efficiently, while also permitting a more complete conversion to dissolved sugars, proteins and carbon dioxide.
