Title: Overflow detection system and its circuit for use in addition and subtraction
Inventor: SUZUKI KAZUMASA
IPC: G06F7/50
Filed: 1992-06-25
Abstract: In an overflow detection circuit for A+B operation, an inverter outputs a value V B, comprising inverted bits of a numeric part of an addend B. A comparator receives as an input a numeric part V A of an augend A and an output V B, of the inventer, and responsive thereto outputs a signal C indicating whether or not V A > V B, is given. Sign parts S A and S B of A and B and the output C of the comparator are inputted into a decoder and an overflow signal "0" is outputted. The decoder is a circuit which outputs "1" when S A and S B are "0" and V A(V A > V B') is large and when S A and S B are "1" and V A is small (VA=V B'), and output "0" in other cases. If the comparator is a circuit for determining V A~V B', the overflow of A+B+1 can be detected. Thus, the overflow of the result of operation can be detected earlier than an adder and a subtracter output the results.

Title: Method and apparatus for measuring irregular tread wear
Inventor: DORY ARTHUR J
IPC: B60C11/24
Filed: 1992-12-16
Abstract: Abstract An apparatus and technique for measuring and analyzing the tread wear of a pneumatic tire. The tire is indexed about its axis. Between the indexing steps, a laser scanner obtains data from the tread surface. This data is normalized to eliminate any out-of-roundness of the tire data. Noise spikes are removed and replaced with values attributable to valid data. From the data, a reference curve corresponding to a lateral sector of the tire is devised. The data from actual lateral sectors is then compared to the reference curve by a curve-fitting process and the deviation between the actual data and the reference curve establishes the degree of irregular wear of the tire at that lateral point.

Title: Closure for a bottle or the like and process for manufacturing it
Inventor: HERTRAMPF MICHAEL
IPC: B65D41/04
Filed: 1991-07-10
Abstract: The invention discloses a closure for a bottle or the like and process for manufacturing it. The closure consists of a retaining part (1) which retains the closure on the bottle neck, a sealing part (2) which is retained by the retaining part and has a substantially annular sealing surface (7), a seal (10) made of compressible material being arranged between the latter and the annular face of the bottle neck. The contact pressure between the seal and the annular sealing surface varies along the latter. The areas of higher contact pressure act as a limit stop and define the position of the sealing part and thus the magnitude of the compression of the areas (8) of lower contact pressure which form the pressure-relief valve. Sealing, limit stop and elastic element can therefore be made very easily by simply fashioning the annular sealing surface or the seal itself.

Title: Portable dedicated electron spin resonance spectrometer
Inventor: BALES BARNEY
IPC: G01R33/60
Filed: 1993-01-20
Abstract: ABSTRACT An electron spin resonance spectrometer which is dedicated to a specific narrow range of tasks is reduced in size such that, as contrasted with the usual laboratory ESR spectrometers, it is easily and readily portable and can be carried to various locations to conduct tests. It uses a much smaller magnet structure than usual, a self contained single board computer, and a microwave source which is adjustable by the computer. The microwave source operates in the 2 GHz range and is connected through a circulator with a matching circuit which inductively couples the microwave signal to a sample chamber/resonator positioned in the magnetic field of the magnet structure. An oscillator provides a audio frequency signal which is combined with a slow ramp signal from the computer to modulate the output of the magnet structure. Reflected energy from the sample chamber/resonator is detected and supplied to a special amplifier which separates detector current and the ESR voltage signal, sending the detector current signal to the computer for controlling the microwave frequency and the ESR voltage to a phase sensitive detector which compares it with the audio frequency reference signal from the oscillator. Most of the noise is removed in the phase sensitive detector since it passes only those parts of the ESR signal which are in phase with the oscillator signal. The computer uses this signal to provide an output and also to provide a correction signal to the matching circuit to maintain the optimum impedance match between the resonator and the matching circuit.
