Title: Rake combining methods and apparatus using weighting factors derived from knowledge of spread spectrum signal characteristics
Inventor: YI-PIN ERIC WANG
IPC: H04B1/712
Filed: 2003-03-14
Abstract: Information encoded in a transmitted spread spectrum signal included in a composite signal is recovered. The composite signal is received from the communications medium, and correlated with a desired spreading sequence to produce a plurality of time-offset correlations. Weighting factors are generated based on knowledge of spread spectrum signals in the composite signal. The correlations are combined according to the weighting factors to estimate information encoded in the transmitted spread spectrum signal. According to one aspect, a composite channel response is estimated from knowledge of the desired spreading sequence and an impairment correlation is determined from an estimate of power of an interfering spread spectrum signal and an estimate of power of noise in the composite signal. The composite channel response and impairment correlation are used to generate the weighting factors. According to another aspect, weighting factors are iteratively generated from an estimated channel response, an estimated impairment correlation, and previously determined weighting factors. Related apparatus are also described.

Title: Method for making corrections, adding material and welding on special metal prostheses
Inventor: VENTURINI DANIELE
IPC: A61C/
Filed: 1991-12-13
Granted: 1995-08-08
Abstract: The invention relates to a method for making corrections, adding material and welding on special metal prostheses in which the correction, filler and welding materials comprise metal powders which are applied to the special prosthesis at the desired points and are then heat treated. In particular to ease such operations and to obtain more accurate work which is more suitable for use the invention provides a method in which the metal powder comprises a powder of a single type of metal or a single alloy which is consolidated by sintering. The metal powder used may be powder of the metal or alloy of which the prosthesis is made or a metal or an alloy whose sintering temperature is below the melting range for the metal or alloy making up the prosthesis, when the latter is not coated with resin or ceramic, while when the prosthesis is coated with ceramic it is a powder of metal or an alloy whose sintering temperature is below the firing/curing range for the ceramic or resin.

Title: Apparato per il selezionamento di capsule di gelatina dura.
Inventor: CANE ARISTIDE
IPC: B07B1/15
Filed: 1991-06-12
Granted: 1995-02-21
Abstract: L'apparato impiega una coppia di pettini rotanti (11-14) coi dischi del secondo pettine interposti tra i dischi del primo pettine e posti superiormente tra spondine fisse di guida (17). I dischi del primo pettine intercettano i flussi delle capsule chiuse, dai quali sono già stati eliminati gli eventuali coperchi senza i fondelli. Le capsule si inseriscono col fondello tra i dischi del primo pettine e rimangono a questi sospese col coperchio (C1). Attraverso i dischi del primo pettine cadono i soli fondelli delle capsule e le eventuali capsule schiacciate. Le capsule trasportate dal primo pettine rotante, giungono sui dischi del secondo pettine, in genere col coperchio in avanti. Il secondo pettine trasferisce le capsule nei canali longitudinali di guida (107') di un corto piano vibrante (7'), dotato nella parte iniziale di ogni canale, di un'apertura longitudinale (19) che lascia passare il fondello ma che trattiene il coperchio delle capsule che in tal modo giungono verticali in un foro (20) di evacuazione. Le eventuali capsule cori due coperchi, superano il detto foro (20) e vengono scaricate nella tramoggia degli scarti.

Abstract: Method and apparatus for casting metal strip in which molten metal is introduced between a pair of parallel casting rollers (16) via a tundish (18) and metal delivery nozzle (19). Casting rollers (16) are cooled so that shells solidify on the moving roller surfaces and are brought together at the nip between them to produce a solidified strip product (20) at the roller outlet. The tundish (18), delivery nozzle (19) and a pair of side closure plates (56) to confine the pool of metal on the casting rollers are separately preheated to working temperature and then rapidly brought into an operative assembly and casting is started before detrimental uneven or localized cooling of the preheated components can develop. To this end the casting rollers are mounted on a carriage (13) movable between a first station (14) at which the preheated components are fitted and a second station (15) at which casting is carried out.
