Title: Method for remodelling a hollow body without the use of tools
Inventor: LEBER HELMUT
IPC: C03B23/047
Filed: 1991-05-01
Abstract: ABSTRACT     There is known a procedure for the tool-free remodelling of a tubular hollow-body of amorphous, especially vitreous, material, into a rod by collapse, in which reduced pressure below atmospheric pressure is maintained in the tubular section by the continuous evacuation of air, with the hollow body being continually brought horizontally to a heating zone at a predetermined rotational speed, where its viscosity is lowered in such a way that this hollow body collapses to form a rod in the field of collapse, due to the difference in pressure between the reduced pressure inside the hollow cylinder and the outside pressure, with the rod being continually removed from the field of collapse at a prescribed rotational speed. In order for such a method to produce homogeneous rod-shaped bodies in a one-stage process at an economical price, the parameters must be selected to ensure that a stem having smaller transverse measurements than the rod forms out of the field of collapse, in the axis of the rod, away from the direction in which the rod is removed. These parameters are: the inner and outer measurements of the hollow body; the viscosity of the vitreous material when in the field of collapse; the difference in pressure between the reduced pressure in the tube and the outside pressure; the speed of withdrawing the rod and the speed at which the hollow body is brought up; as well as the rotational speeds of the rod and hollow body.

Abstract: 2041636 9105413 PCTABS00004 A cellular radiotelephone autonomous registration method. The radiotelephone attempts registration when a clock count transmitted by the system equals or exceeds the radiotelephone's threshold count. The radiotelephone then scans available channels for proper signal strength and attempts to seize that channel. If the channel seizure fails, the threshold count is updated with the clock count plus a random integer and the next channel seizure attempt is made when the next master clock value equals or exceeds this value. This method increases the length of time between failed channel seizure attempts, thereby decreasing the load on the radiotelephone's power source.

IPC: H03M7/40
Filed: 1991-05-06
Abstract: Abstract Of The Disclosure A data separator for use in synchronizing data derived from a floppy disk or similar data source provides a variable net gain or loss of charge to vary the frequency of a voltage-controlled oscillator in accordance with the relative position of the data with respect to the clock until data centering or synchronization is achieved. The net charge is derived from a charge pump circuit that is controlled by a charge pump-up signal whose duration is proportional to the detected phase difference between the data and the clock, and a charge pump-down signal whose duration is one clock cycle.  When the data pulse is centered within a clock cycle, the duration of a pump-up signal is one half that of a pump-down signal.

Title: Minimum difference processor
Inventor: SACKS JACK M
IPC: G06T5/00
Filed: 1992-01-30
Abstract: A process for reducing background clutter of a scene, and thus, isolating an object of interest.  The process includes calculating a minimum output from a plurality  of  appropriately  configured  anti-median filters  representing a minimum difference processor (MDP) filter.  In a first preferred embodiment, the MDP filter includes a (5 x 5) matrix of elements wherein each element has an intensity value representation of the  scene.    A  first  anti-median filter  array  is configured as a horizontal array of 5 pixel elements in which the center element of the matrix is the center element of the horizontal array.  A median value of the 5 elements of the horizontal array is determined, and is subtracted from the value of the center element to determine an anti-median value of the horizontal array. The same process is performed for a vertical 5 element anti-median array,  and two diagonal 5 element anti-median arrays, all including the center element of the matrix as the center common element of the arrays.  Once the anti-median value of each array is determined the lowest anti-median value is outputted as the output of the MDP filter.  In a second preferred embodiment, the values of the remaining elements of the matrix which were not included in any of the horizontal, vertical or diagonal arrays described above are subtracted from the center element of the matrix.  Again, the lowest value from the group of anti-median values together with the remaining subtracted values is outputted as the output of the MDP filter.  This process enables the background clutter of the scene to be substantially suppressed or eliminated.

Abstract: ABSTRACT OF THE DISCLOSURE   An electronic timing control system for a glassware-forming machine includes a mini-computer master controller which controls the timing and sequence of operation of each of the individual section glassware-forming machine components.  The master controller includes a plurality of control modules for section timing, conveyor motion, etc., each module of which outputs information to a corresponding serial multiplex I/O module.  Each of the I/O modules connected to the master controller feeds data to a common data cable, according to a multiplexing scheme administered by the master controller.  Data from the data cable is fed to each of the sections of the I.S. glassware forming machine, and particularly to a plurality of serially connected serial multiplexer modules.  Each of the serial multiplexer modules corresponds to a section functional component operable to receive and form molten glass gobs into glassware articles.  Each serial multiplexer module has a unique address.  Information conveyed by the data cable includes a specific address for the module to which the data being transmitted is to be provided.  Thus, although control data from the master controller is provided serially to all of the multiplexer I/O modules, only that module corresponding to an address transmitted by the controller is permitted to receive the data.

Title: Bidirectional data transmission on an optical waveguide
Inventor: HUYNH HON
IPC: H04B10/25
Filed: 1992-05-27
Abstract: ABSTRACT OF THE DISCLOSURE         A method is disclosed for digital bidirec-tional data transmission on an optical waveguide.   For either direction of data transmission,  light pulses having the same frequency are used.  The pulses to be transmitted are reduced from an original width Tb to a width Tr, so that the pulse-to-pause ratio Tr/(Tb - Tr) is smaller than one.  A second transmitter/receiver unit is allowed to transmit during a reception pause (Tb - Tr) only.  In order to achieve an optimum distribution  of the  optical  pulses  on the optical waveguide 3, the first transmitter/receiver unit 1 measures the timing on the optical waveguide 3 and,  if required, causes the second transmitter/receiver unit to modify  the  transmission  time  of  its  optical  signals. Thereby,  a  control  loop  is  established,  automatically achieving an optimum pulse distribution on the optical waveguide, within certain limits.
