Abstract: APPARATUS AND PROCESS FOR MAKING COATED FASTENERS            ABSTRACT OF THE DISCLOSURE     Disclosed is an apparatus for applying patches of resin to internally threaded articles having openings at both ends comprising a support for positioning the internally threaded articles for processing, means for heating the articles to a temperature above ambient temperature and means for providing a stream of fine particles of the resin entrained in a gaseous jet. A spray guide applicator is provided for directing the stream of resin particles through the opening at one end of one of the articles against an area of the threaded portion of the one article to cause the resin particles to be retained by the articles and to adhere to the threaded portion area.  The applicator comprises an elongated conduit portion and a nozzle portion, the conduit portion having a passageway therein, and the nozzle portion having top, bottom and side walls, the bottom wall having an opening communicating with the passageway.  A slot opening is disposed in the sidewall in a plane forming substantially a right angle to the passageway, the top wall forming a deflector surface for the stream of resin particles, whereby the stream of resin particles is directed in a line of discharge against the threaded portion of the article in a controlled manner.  The invention also comprehends the process associated with applying such patches.

Abstract: ABSTRACT OF THE DISCLOSURE   Effective  processes  of  preventing  the oxidation of metal   objects  by  capacitive  coupling  are  disclosed. These  processes are particularly suited to preventing the oxidation  of  metal objects which are not grounded to the earth,  such  as  automobiles and trucks.  These processes significantly  reduce  the rate of oxidation of such metal objects.   An electric current is impressed into the metal object  by treating the metal object as the negative plate of  a  capacitor.    This  is  achieved  by  a  capacitive coupling  between  the metal object, a dielectric material and  a  positive  plate.    Pulses  of  direct current are provided  to  the  positive  plate. The metal object has a common  ground  with  the  means for providing the pulses. When  the  metal object is not grounded to the earth, then the   preferred  process  includes  means  to  provide  an electrical  connection between the positive plate and the earth  ground  through  a  high  voltage  diode  which  is adapted  to  allow  the  flow  of electrons from the earth ground  to  the  positive  plate  but  prevent the flow of electrons from the positive plate to the earth ground.

Abstract: Abstract of the Disclosure A computer program is verified, unit by unit, by automatically instrumentating the code and generating a test driver   program   which   executes   all   branches   of   an instrumented  code  unit.    The  code  is  instrumented  by operating processors to standardize the code for at and to insert  executable  tracer  statements  into  each  block  of reformatted code between control statements.   A pseudocode having only control statements and tables identifying valid linkages between blocks of code are generated by another processor for use by a verifier in selecting values of input variables and expected outputs for test cases which execute each block of code in the selected unit.  Another processor generates the test driver program from the test cases and a software test specification identifying the test cases and expected results.  The test driver program and instrumented code unit are compiled and linked to repeatively execute the instrumented  code  unit  to  implement all  the  test  cases.          Results of the test cases are printed out indicating the sequence of block linkages generated by each test case, the expected output values and the actual output values.

Title: Trunked radio repeater system
Inventor: CHILDRESS JEFFREY S
IPC: H04L1/16
Filed: 1989-02-23
Granted: 1991-10-01
Abstract: TRUNKED RADIO REPEATER SYSTEM     ABSTRACT A digitally trunked radio repeater system provides substantial improvements in timeliness of channel acquisition and channel drop, and in reliability of critical control signalling.  The system uses a much higher digital signalling rate than is typically found in prior art systems, and uses a control channel to convey digital channel request and assignment messages between the central site and mobile transceivers.  The mobile radio transceivers transmit channel requests on the control channel (if no response is received, the mobile retries during a retry time window which increases in duration in dependence on the number of retries).  The mobile transceiver switches to a working channel in response to an assignment message received on the control channel.  Subaudible digital signals transmitted on the control channel and on active working channels allow late entry, shifting to higher priority calls, and other advanced functions.  Message and transmission trunking capabilities are both present so as to maximize working channel usage without compromising channel access for high priority communications.  During transmission trunking, called and calling transceivers return to the control channel after each transmission (and called transceivers may be inhibited from transmitting) but grant higher priority to calls from the other transceivers being communicated with to ensure continuity over an entire conversation.  Additional functions and fault tolerant features further increase the versatility and reliability of the system.
