Abstract: ABSTRACT:              In this transmission system using differential PCM, the local decoder incorporated in the loop of the encoder and the remote decoder comprise  identical filters (5) and (15) each constituted by a cascade arrangement of several filtering setions (Fl-FN) of the first and/or of the second order; each section may have one or two con-trollable coefficients, which are modified at each sampl-ing instant by a modification term which depends upon the product of the difference signal (e) produced in the encoder and the gradient of the differencesignal (e) with respect to the controllable coefficient.  When the filter-ing sections (Fl-FN) are recursive, the gradients are obtained by applying a signal corresponding to the dif-ference signal (e) to identical recursive sections (F'l-F'N).  When non-recursive filtering sections (Hl-HL) are used, the gradient calculations sections (H'l-H'L) are recursive with a transfer function inverse to that of the sections (Hl-HL).  This system is in-tended to be used for the transmission of signals in tele-phone networks.

Abstract: APPARATUS AND METHOD OF PHASE CONTROL FOR RESISTANCE          WELDING AND OTHER RESISTIVE-INDUCTIVE LOADS     Abstract of the Disclosure A computer-controlled welding apparatus includes a phase-controlled resistance welding circuit (A) for selectively conducting pulses of a welding current to a workpiece (B) and a control circuit (C) for controlling the conduction of the welding current.  The control circuit includes a line clock generator (30) for determining the beginning of each voltage half line cycle and a conduction sensor (34) for determining whether or not a contactor (14) is conducting current to the workpiece.  A microcomputer (40) is preprogrammed with a plurality of power factor correction curves, each of which represents weld current vs. firing angle for a fixed hangover angle.  The computer is programmed to select one of the power factor correction curves.  If the preceding half line cycle was conductive, the program selects the curve which corresponds to the hangover angle of the preceding half line cycle.  If the present half line cycle is the first conductive half cycle in weld, the program selects the curve corresponding to a hangover angle of about 87°.  During pulsation welding, the curve is selected based upon the hangover angle of the most recent conductive half cycle and the number of nonconductive half cycles therebetween.  During each half cycle, the present angle (duration since the beginning of the half cycle) periodically addresses the curve and a corresponding weld current is retrieved.  The retrieved weld current represents the weld current which would be produced if the contactor were rendered conductive at the present time, i.e., the present weld current.  A comparator (86) compares a preselected weld current for the present half cycle with the present weld current.  When the present weld current becomes coincident with the preselected weld current, the contactor is rendered conductive.

Title: Systeme de chauffage central par air chaud

Abstract: L'invention concerne un système de chauffage central de type auto-régularisé. Ce système comprend un conduit central disposé sous le plancher d'une maison à chauffer. Une pluralité de bouches d'entrée d'air froid placées au niveau du plancher aux endroits les plus froids de la maison, sont toutes raccordées au conduit central. Ce dernier est lui-même raccordé à une chambre de compensation verticale comprenant, dans son extrémité inférieure, un échangeur de chaleur et, dans son extrémité supérieure, au moins une bouche de sortie d'air chaud. L'échangeur de chaleur associé à la chambre de compensation est lui-méme relié à au moins une source chaude maintenue à une température donnée. En opération, la simple différence de gravité entre l'air froid et l'air chaud amène l'air froid de la maison à tomber via les bouches d'entrée et le conduit central jusque dans le bas de la chambre de compensation où ledit air froid est réchauffé au contact de l'échangeur de chaleur relié à la source chaude. Cette même différence de gravité amène l'air réchauffé au contact de l'échangeur de chaleur à monter naturellement dans la chambre de compensation jusqu'à la bouche de sortie. Toute la chaleur perdue par l'échangeur de chaleur au contact de l'air froid est automatiquement compensée par la source chaude qui, de ce fait, détermine par sa propre température la température ambiante de la maison à chauffer.

Abstract: ABSTRACT OF THE DISCLOSURE         The specification discloses a method for making a curved, conductively coated glass member, and the resulting product, by providing for a sufficient degree of substoichio-metry at the moment of bend that the glass can be bent using conventional bending techniques without crazing the coating.          Two alternative methods for achieving the degree of substoichio-metry are disclosed.  One involves coating the part to an initial light transmittance (T0) which is lower than that typically sought by prior artisans.  The other involves bend-ing the part in a reducing environment.  Also disclosed is a method for increasing conductivity of the coating by expos-ing the coated part to a reducing environment at temperatures considerably higher than those heretofore thought feasible for use in reduction curing.
