Abstract: APPARATUS FOR AND METHODS OF PRODUCING A HOT ASPHALTIC MATERIAL                            ABSTRACT         A continuous process aggregate drying and mixing plant for producing a hot asphaltic material,  such as  is used for paving highways or the like,  includes a combination of a drum drier and a pugmill.   Both the drum drier and the pugmill are supported by a common trailer frame.   The pugmill is coexten-sively mounted at the discharge end of the drum drier towards the rear of the frame.   The drum drier discharges dried and heated virgin  aggregate material  through  a  feed  and transfer  chute directly into a first, pre-mix region of the pugmill.  The feed and transfer chute also provides for the addition of recycled pavement to the heated and dried aggregate and for the side dis-charge of such heated and dried aggregate.   A second region of the pugmill within which liquid asphalt is added to the mixed aggregate  is  substantially  separated  from the  first,  pre-mix region.   The space above the second region of the pugmill is substantially enclosed and coupled directly to a secondary air supply of a burner for the drum drier.   Thus, vapors emanating from the second region of the pugmill are drawn into the burner and burned to form environmentally friendly products.

Title: Communication unit comprising caller identification function and caller identifying method in a digital communication network
Inventor: KATSURADA MORIHIRO
IPC: H04M1/57
Filed: 1990-07-10
Granted: 1996-04-30
Abstract: A communication unit utilizes a caller management unit which monitors in-house lines and detects a caller side calling code included in a calling set up message applied at the time of reference.  A control unit stores the detected calling code in one memory region of a memory and reads out the stored calling code from the memory region in response to an output request to produce information corresponding to the  calling  code.    The  management  unit  displays  the information produced by the control unit.  The memory has another  memory  region  for  storing  a  plurality  of predetermined  calling  codes  and  caller  specification information corresponding to each calling code.  The control unit stores the detected calling code into the one memory region in response to a non-response detection to reference by the line monitor.   The control unit further makes a determination whether a calling code coinciding with the calling code stored in the one memory region is stored in the other memory region in response to an output request and displays the caller specification information corresponding to the calling code when coincidence is detected,  while displaying only the detected  calling code when  a  non-coincidence is detected.

Title: Light weight drive shaft
Inventor: SIMON JOSEPH A
IPC: F16C3/02
Filed: 1991-01-22
Granted: 2002-01-15
Abstract: A light weight drive shaft, such as for use as an automotive vehicle engine drive shaft for transmitting engine power, is extruded from a tubular metal blank into an elongated tube having integral center and opposite end sections, with the center section having a thin wall and the end sections having a thick wall. The shaft is formed by inserting a tubular blank within a tubular die having a constricted die throat through which the blank is extruded. A punch having a lead end punch extension, is inserted within the die, against the trailing end of the blank, with its extension extending part way into the blank. Movement of the punch towards the die throat extrudes the blank through the throat, causing the leading portion of the blank to collapse inwardly to form the thick wall end section until continued movement of the punch positions the extension within the die throat. Thereafter, further movement of the punch extrudes the thin wall center section with the punch extension acting as a mandrel, until completion of the desired center section length. Then, the punch is removed from the die end blank and a second blank is inserted in the die and the punch is reinstalled within the die with its extension extending part way into the second blank. Movement of the punch towards the throat now completes the extrusion of the trailing end portion of the first blank, due to the pressure of the second blank, with the trailing end portion of the first blank and the leading end portion of the second blank collapsing inwardly to form their respective thick wall end sections, until the first blank is completely extruded. Once extruded, splines are formed on the exterior of at least one of the thick wall end sections. Thereafter, the cycle is repeated.
