Title: Egaliseur de viterbi pour recepteur radio
Inventor: BORTH DAVID EDWARD
IPC: H04L25/03
Filed: 1992-08-14
Granted: 1998-05-05
Abstract: Égaliseur Viterbi (366) permettant le décodage d'un signal modulé DQPSK .pi./4. Comme les valeurs de symboles adjacents d'un signal DQPSK .pi./4 sont déphasées les unes par rapport aux autres, les valeurs des états successifs d'un signal DQPSK .pi./4 sont au nombre de quatre. Les trajets de signal de l'égaliseur Viterbi sont ainsi numériquement limités à quatre états consécutifs admissibles (600) et l'égaliseur Viterbi (366) permet de sélectionner à des intervalles voisins certains des trajets reliant les états en tant que trajets survivants afin de former ainsi des trajets à vraisemblance maximale.

Title: A procatalyst for polymerization of olefins containing a trans-esterification product of a lower alcohol and a phthalic acid ester
Inventor: GAROFF THOMAS
IPC: C08F10/00
Filed: 1992-03-23
Granted: 2003-12-09
Abstract: In the invention a procatalyst composition intended for the polymerization of olefins has been provided, which has been prepared by bringing together magnesium chloride, a lower alcohol, a titanium compound and an ester of phthalic acid. The procatalyst composition is active and stereospecific and it simultaneously has a titanium and phthalic acid content as low as pos-sible. These good properties have been achieved by carrying out a trans-esterification between the lower alcohol and the ester of the phthalic acid, whereby the alcoxy group of the phthalic acid comprises at least five carbon atoms.

Title: Apparatus for securing a load-carrying implement to a lifting member
Inventor: DIX MARK J
IPC: B65F1/14
Filed: 1994-03-24
Granted: 1998-08-04
Abstract: Apparatus are disclosed for securing an implement to a rigid longitudinally extended lifting member.  A representative embodiment comprises a clamp that can be mounted to a forklift implement and/or socket for receiving a lifting member.  A working surface engages the lifting surface of the lifting member.  A cam is pivotably mounted on an axis transverse to and displaced from the working surface. The cam has an outwardly radiating spiraled engagement lobe that presses against the under-surface of the lifting member so as to press the lifting member between the working surface and the cam.  Thus, the cam allows the clamp to be moved rearwardly but not forwardly on the lifting member.  The cam, which is biased, can be characterized by having a fixed axis, being self-locking, and/or having a constant contact angle with the underside of the lifting member.  The cam can also have a release lobe adapted to engage a reference surface for releasing the engagement lobe from the lifting member whenever the clamp is placed upright on the reference surface.  The clamp can have multiple cams either similarly or differently sized.  Differently sized cams allow the clamp to engage a wider range of lifting-member thicknesses than single-cam clamps.

Title: Method and apparatus to provide freeze protection for solar water heating systems
Inventor: HART DOUGLAS ROBINSON SANFORD
IPC: F24J2/46
Filed: 1995-01-13
Granted: 1999-01-19
Abstract: A method and apparatus is described to prevent freezing in the piping and tank of a solar water heating system mounted above a heated space. The supply and return piping to the solar water heater is used in conjunction with a heat exchanger mounted within the heated space below, to create a mechanism for the gentle circulation of water by natural convection, sufficient to prevent freezing in the tank and piping. Bypass pipes that incorporate flow restrictions are introduced between the supply and return piping both in the building and just below the solar tank. This creates a loop in the piping which allows natural convection to occur. The flow restrictions are provided so as not to short circuit the normal water flow under conditions of hot water demand.

Abstract: A reaction hydraulic turbine used for converting the energy of a flowing stream into mechanical energy of a rotating shaft is disclosed. In the turbine, the blades have a specifically-designed configuration suitable for not only reducing the hydraulic resistance but also for concentrating the energy of the flowing stream onto the blades. The internal surface of each blade has a half-circular curved section, while the external surface has a streamline section, which is smoothly put into or come out of water thus being almost completely free from hydraulic resistance. At the lowermost portion of the turbine, the energy of the flowing stream is effectively concentrated onto the curved internal surface of each blade.
