Abstract: A pharmaceutical oral controlled release multiple-units formulation in which individual units comprise cross-sectionally substantially homogeneous cores containing particles of a sparingly soluble active substance, the cores being coated with a coating which is substantially resistant to gastric conditions, but which is erodable under the conditions prevailing in the small intestine, in particular an enteric coating which is substantially insoluble at a pH below 7 such as Eudragit<sup>0</sup> S (an anionic polymerisate of methacrylic acid and methacrylic acid methyl ester), is prepared by a process comprising comminuting an active substance together with a substance which is readily soluble in intestinal fluids such as an anionic detergent to obtain particles containing the active substance in intimate admixture with the readily soluble substance, combining the resulting particles into cross-sectionally substantially homogeneous cores together with components which accelerate the disintegration of the cores in intestinal fluids such as talc and sucrose, coating the individual cores with the coating, and combining a multiplicity of the coated cores into a capsule or tablet formulation.As the coating is erodable in an alkaline environment only, the active substance is not released until the units arrive at a section ofthe small intestine with an alkaline pH. Thus, a reduction and delay of the peak plasma concentration is obtained without affecting the extent of drug availability.A coating of the above-defined type may also be used when the active substance is a substance which exerts an irritating effect on the gastric mucosa and/or is unstable in an acidic environment.

Granted: 1996-08-06
Abstract: A congestion avoidance control system and method for a communication network for determining one of routes between a plurality of communication terminals connected to a plurality of exchanges in turn interconnected by a plurality of lines to establish a tandem connection while relieving call congestion to a specific exchange and minimizing the occurrence of call loss.  For each of the relay lines, a resitive value indicative of a reciprocal of a ratio of a relay line residual capacity to an intra-network line full capacity is set and multiplied by a relay line load value to obtain a route load value of the relay line to prepare an output-line residual-capacity minimum-cost vector table.  Further, an application data to be issued from an outgoing terminal includes a cost value allowable for communication route between the outgoing and incoming terminals,  in which case each of the exchanges selects one of the routes forming minimum cost lines of maximum one of line residual capacity classes satisfying a request use capacity issued from the outgoing terminal and having a minimum cost value in an allowable cost range of the application data issued from the outgoing terminal.  Furthermore, the application data to be issued from the outgoing terminal includes a terminal priority level set for the outgoing terminal of the incoming exchange, in which case each of the exchanges has a line T level table in which possible or impossible call registration is stored for line residual capacities with respect to each line and terminal priority level and selects one of the route forming minimum cost lines of the line residual capacity classes associated with the terminal priority level.

Abstract: METHOD OF DETECTING CLUTCH TIE-UP   DURING TRANSMISSION SHIFTING             ABSTRACT OF THE DISCLOSURE        The disengagement of the off-going clutch is monitored to determine as early as possible if there is a clutch tie-up due to failure to disengage.  Beginning at the initial clutch release command, the turbine speed and output speed are used to determine if clutch slip has occurred and a pass signal is given if slip occurs in several consecutive control loops.  Beginning a preset time after the command to fully exhaust the clutch, the number of no-slip conditions are counted. A fail signal is given when a set number of no-slip conditions are counted.

Title: Air curtain fume cabinet and method
Inventor: ETKIN BERNARD
IPC: B08B15/02
Filed: 1990-11-22
Granted: 1994-08-02
Abstract: An air curtain fume cabinet, in which an air curtain jet is directed across the face opening to an exhaust duct. Sufficient flow is exhausted at the exhaust duct to swallow (i) the entire air curtain jet, plus (ii) all of the air which the jet entrains from outside the face opening, plus (iii) a substantial additional amount of air.  This greatly increases the velocity of air moving into the curtain at its  top,  beyond  the  normal  entrainment  velocity,  and prevents spill-back of jet air to the outside even with substantial crosswinds.   Preferably the ratio of exhaust flow to jet flow is between 2 and 3 for a jet height to jet thickness ratio of up to about 15.  Preferably auxiliary air is supplied to the working space interior to replace air entrained into the jet from inside the working space.
