Abstract: A wireless communication system automatically attempts to reconnect when a dropped call is detected. A call may be originated by the mobile station or as the result of a base station page. When a call is originated by the mobile station, the mobile station will attempt to reconnect the call when an interruption of service is detected. When the call is the result of a base station page, the base station will attempt to re-page the mobile station after an interruption of service. Audio indicators may be played to the users indicating that service was interrupted and a reconnection attempt is in progress.

Abstract: A new and improved apparatus is disclosed for screening telephone calls. The apparatus would be a device which would be electronically connected to a phone line in between a telephone and a wall jack. The apparatus would have a programmable numerical key pad and also would have a top-mounted speaker. The apparatus would serve as an interceptor of telephone calls. Once another person would call a person who had the present invention, the other person would have to enter a 2/3 code within ten to twelve seconds, or they would be cut off. If the other person entered the correct code, the present invention would play an eternal melody note that would indicate a welcome call.

Abstract: The invention relates in the first instance to apparatus for dispensing granular material, for example plastics granules dosed with a coloring agent. Granular material and the coloring agent are located in supply hoppers and metering means feed predetermined metered quantities to a mixing device which supplies the dosed material to a supply hopper. The apparatus is arranged to operate when the level of dosed material in the supply hopper falls below a predetermined level, whereupon actuation of the metering means causes automatic replenishment to that level.In a second embodiment of the invention there is provided a shroud, such that the materials are discharged within the shroud to contact a mixer blade and then fed to the injection molding machine.The invention also contemplates a metering device including a cylinder with an opening in its wall to communicate with a measuring chamber located within the body of the cylinder.
