Title: Bar code reader
Inventor: TAKENAKA SHINYA
IPC: G06K7/10
Filed: 1990-07-05
Granted: 1996-12-10
Abstract: A bar code reader reads a bar code by scanning a laser beam on a screen on which the bar code is displayed.  The bar code reader has a beam scanning device for scanning the laser beam irradiated from a laser oscillator.  The beam scanning device has a polygon mirror which is rotated and driven around an axis.  The polygon mirror forms at least two kinds of flat reflecting surfaces for respectively scanning the laser beam along with the rotation of the polygon mirror.   Scanning angles by the reflecting surfaces are twice as large as opposite angles to which the reflecting surfaces correspond respectively.  The laser beam is scanned at two or more kinds of scanning angles,  that is,  scanning angles and which are respectively adapted to the long and short bar codes. Therefore,  the bar code can be accurately read irrespective of a length thereof.

Granted: 1994-08-02
Abstract: ABSTRACT OF THE DISCLOSURE    In a telephone system, a composite detection circuit and method for use in mechanized loop testing to detect both AC ringing and DC coin control voltage at a test access unit.  An equalization circuit distinguishes between the two voltages and selectively amplifies the DC components of the voltages, thus amplifying the positive DC coin control voltages out of the detection range of the negative AC ringing voltages and vice versa.  Two distinct outputs indicate either a positive or negative voltage detected. Two identical circuits are used, one on the ring line and one on the tip line, to detect positive and negative ringing and coin control voltages.

Title: Dynamic weight control system
Inventor: RUPPEL ROBERT F
IPC: G05B15/02
Filed: 1991-12-23
Granted: 1996-04-02
Abstract: The present invention relates to a dynamic weight control system for a slicing machine, used to slice bacon or other food products, that has both primary and secondary weighing systems.          The slicing machine has a slicing blade and a feed mechanism for feeding a food product (e.g., a bacon slab) into the slicing blade at a controlled rate.   The primary weighing system controls primary slicing and weighing of multi-slice drafts of the sliced products so that each draft is an approximation of a prescribed control weight.   The secondary weighing system checks draft weights and supplies data to a computer that computes an average weight for those drafts that are within an acceptable weight range; it also computes the pass ratio of acceptable weight drafts for a sample group of drafts.   The pass ratio computation is used to make incremental adjustments in a target weight and the secondary system then computes a dynamic weight correction based on the adjusted target weight; the weight correction is fed back into the primary weighing system where it is used to adjust the control weight, with no operator intervention required, to reduce weigh giveaway.

Granted: 1998-07-07
Abstract: A performance monitoring technique which allows faults within an optical communication system to be detected and located. More specifically, a technique employing a signal generator to controllably insert maintenance signals at the input and output of each module within an optical communication system, and a single monitor to receive the inserted maintenance signals at a fixed point within the system, and, in response, determine the location of faulty modules. The monitor analyzes the received inserted maintenance signals, and locates faults by pinpointing modules from which a maintenance signal inserted at the module output is received uncorrupted by the monitor, but which return a corrupted maintenance signal whenthe insertion is made at the module input. A particular embodiment of the invention enables the maintenance signals to be inserted via pre-existing control drivers within system modules. This allows optical losses with the system to be minimized by eliminating the need for introducing of additional optical couplers or attenuators into the system.

Title: Spray unit for cooling extruded sections
Inventor: PLATA MIROSLAW
IPC: B21B45/02
Filed: 1993-06-10
Granted: 1999-02-16
Abstract: The spray unit lies downstream, in-line with an extrusion press and serves to cool metallic sections (18) in particular sections of aluminium or an aluminium alloy from all sides. The cooling medium emerges from spray nozzles programe-controlled in the direction of the section (18). The distance (a, b, d), the cross-section distribution and the direction of the spray nozzles are adapted specific to the geometrical shape and distribut-ion of mass in the section (18). The optimum parameters are determined and stored in the unit processor. The spray nozzles (28) are arranged in nozzle beams (22) running in the direction (16) of the extruded section (18). The nozzle beams (22) comprise at least one longitudinal water channel (W', W:" and two longitudinal air channels (A', A"), whereby cross-intersecting channels (31, 33) branch off from the water channels (W', W") to the spray nozzles (28) and the air channels (A', A") terminate in air gaps (39, 41) which are directed towards the nozzle outlets (38).   The extruded sections (18) are passed through the spray unit and cooled, at a rate that exceeds the critical cooling rate specific to the material, by a programme controlled, sprayed cooling medium in a manner that takes into account the shape of the section and the distribution of mass in the section. Using uniform cooling on all sides, sections (18) that are extrud-ed straight can be kept straight, while sections that are distorted on extrusion can be corrected with respect to bending and/or twisting by non-uniform cooling.

Abstract: A method of making a casting having an internal passage involves the steps of forming a core having an external surface configured to form the passage in the casting and having a plurality of integrally formed protrusions extending from the external surface at stressed regions thereof (e.g., thermally stressed regions) prone to be distorted from a master core con-figuration, and positioning the core in a pattern molding cavity by engagement of the protrusions with rigid walls defining the molding cavity such that the core is conformed substantially to a predetermined and/or empirically determined relationship between the master core configuration and the molding cavity as if the core corresponded to the master pore configuration.      A fugitive pattern corresponding to the casting to be formed is then molded about the external surface of the core while the core is supported in the aforementioned relationship relative to the molding cavity, whereby the wall thickness of the pattern is controlled about the core. A ceramic shell mold is then invested about the pattern and core such that the protrusions can engage the mold in the event of core movement during subsequent steps. The molded pattern is selectively removed from the invested shell, leaving the core spaced from the shell in a shell mold casting cavity by the protrusions in accordance with the aforementioned relationship between the master core configuration and the pattern molding cavity, whereby the wall thickness of the casting formed therein is controlled. Molten metal is then solidified in the shell mold about the core. After the metal is solidified, the shell mold and core are removed by conventional techniques to free the casting.      The casting may have holes in the wall thereof in communication with the internal passage where the protrusions formerly resided.
