Abstract: The invention relates to a receiver for a digital transmission system comprising a transmit channel having a storage depth n with an analog signal processing section, which receiver comprises an analog-to-digital converter and an equalizer which has a digital signal processing section that includes a memory means with a register for storing state transitions.        For a reduction of manufacturing costs there is proposed that the registers (331, 332, 333) of the memory means (33) all comprise 2n'memory locations, with 1<= n' < n, that the memory means (33) comprises a memory path register (334) in which at each discrete instant (i) at least n previous bits (b i-1, ..., b i-n, b in'-1,...,b i-n, ...) are stored for 2n' states commencing at a first previous bit (b i+1). A  minimum "0"-path or minimum "1"-path respectively, and the assigned overall probability parameters are formed by means of the bit sequences of all the 2n' possible "0"-paths or "1"-paths respectively, having the smallest probability parameter. The binary value which is assigned to the smaller of the two considered overall probability parameters has an estimate ~ for the bit b i-n' and reliability information P(~) for this estimate ~ is formed on the basis of the two considered overall probability parameters.

Title: Injection molding sealing collar with a central hot tip shaft
Inventor: GELLERT JOBST U
IPC: B29C45/30
Filed: 1991-12-11
Abstract: This invention relates to a hot tip gated injection molding apparatus having a heated manifold to distribute melt to a number of spaced gates. An unheated sealing and conductive member is mounted directly between the heated manifold and the cooled cavity plate in alignment with each gate. The sealing and conductive member has an elongated hot tip shaft which is connected to extend centrally through the bore of an outer collar portion by a number of spaced spiral blades. The collar portion bridges an insulative air space between the hot manifold and cooled cavity plate to prevent melt leaking into it. Heat received through the rear end of the collar portion which abuts directly against the heated manifold is transferred through the blades and the hot tip shaft to the gate area which is aligned with the pointed forward end of the hot tip shaft. The rear end of the hot tip shaft extends rearwardly into a branch of the melt passage to pick up heat from the surrounding melt. The hot tip shaft has a highly conductive inner portion inside an abrasion resistant outer portion to conduct heat to and away from the gate area during different parts of the injection cycle. The spiral blades impart a swirling motion to the melt which flows between them.
