  • Patent number: 4310562
    Abstract: This invention provides an apparatus and process for automatically coating solid pharmaceutical dosage forms, e.g., tablets. The apparatus comprises a coating pan, having a rotating means, e.g., motor and a weighing means, e.g., scales in combination with the pan and motor. A process controller is in electronic communication with both the pan motor and scales, for controlling the pan rotation and monitoring the weight of the coating pan contents. There is also provided a plurality of material containing reservoirs having conduit means communicating with the interior of the pan. The material containing reservoirs may also have weighing means, e.g., scales in combination with the reservoirs, which are also in electronic communication with the process controller. These reservoirs may contain a water supply, a coating syrup supply, color suspension supply, and polishing ingredients for use in coating the tablets.

  • Patent number: 4269821
    Abstract: There are described processes for the preparation of submicroscopic particles of physiologically acceptable polymer associated with a biologically active material, by polymerizing a monomer in the presence of the biologically active material or by adsorbing the biologically active material upon preformed submicroscopic polymer particles. Where the biologically active material is an antigen, the particles are useful as constituents of injectable vaccines having an adjuvant effect.

  • Patent number: 4155357
    Abstract: Normal breathing cycles of a ventilator cause an alarm controller circuit to emit a periodic pulse which resets a timer circuit thereby maintaining an alarm device in an "off" condition. Patient disconnect is sensed by an alarm trigger circuit which sends an inhibit pulse to the controller circuit inhibiting the timer circuit reset pulse. This causes the timer to "time out" thereby turning on an alarm actuator circuit which causes an audible and/or visual alarm condition.
