Title: Implement control system
Inventor: BELLANGER REGIS
IPC: A01B63/00
Filed: 1987-04-09
Granted: 1993-02-09
Abstract: ABSTRACT               IMPLEMENT CONTROL SYSTEM          A tractor implement draft force control system in which desired and actual implement draft force values are compared to provide a draft force error signal (DE).  The system is responsive to the error signal to control the working depth and hence the draft force of the implement (50).  A deadband (DB) operates on the error signal to render error signals within the deadband ineffective to control the working depth of the implement and a deadband control means (30) adjusts the width of the deadband so that the deadband width is maintained dependent on components of the error signal above a predetermined frequency.  Thus the system can be arranged not to respond to high frequency spurious components of the draft force signal but is able to respond to the lower frequency components of this signal which are representative of the true draft force variations.

Title: Blow molding method and apparatus
Inventor: SADR CHANGIZE
IPC: B29C49/48
Filed: 1987-06-18
Granted: 1990-09-11
Abstract: ABSTRACT OF THE DISCLOSURE When blow molding elongated serpentine tubes or similar articles, loading of the mold cavity with the parison can present a problem. The parison can stick against the wall of the mold cavity. Moreover, a large diameter parison must be used, i.e. the parison must have a diameter equal to the total width dimension of the article, and consequently a large volume of flash is produced. The flash must be trimmed and recycled. In order to avoid these problems, inserts are placed in the mold to define portions of the mold cavity, particularly at corners. Air under pressure is fed into passages in the outer surfaces of the inserts and discharged through small orifices in such inserts against the parison to guide and drive the latter fully into the mold cavity. A vacuum can also be applied to the end of the cavity remote from the parison entry point for drawing the parison into the mold.

Granted: 1993-08-17
Abstract: Abstract of the Disclosure A phase signal estimator receives a first phase signal having a first frequency and generates a first filtered signal phase-locked with the first phase signal as an estimated phase signal.  A phase locked loop sec-tion receives a second phase signal having a second fre-quency which corresponds to a predetermined multiple of the first frequency of the first phase signal, and out-puts a second filtered signal phase-locked with the second phase signal as a desired phase signal.  In the phase locked loop section, a phase comparator receives the second phase signal and the desired phase signal and generates a phase difference signal.  A filter low-pass filters the phase difference signal from the phase com-parator.  A signal generator generates a signal having a predetermined frequency in accordance with the output from the filter.  A phase adder adds the signal having the predetermined frequency from the signal generator and the estimated phase signal from the phase signal estimator and outputs the desired phase signal.  A fre-quency compensator is selectively connected to the esti-mated phase signal, the second phase signal, and the desired phase signal so that the phase locked loop sec-tion has substantially the same low-pass filtering response characteristic as the first frequency of the first phase signal.

Abstract: HIGHLY DENSIFIED VOLTAGE NON-LINEAR RESISTOR      AND METHOD OF MANUFACTURING THE SAME                 Abstract of the Disclosure In case of manufacturing a voltage non-linear resistor, a sintering process is divided into two completely separated steps, i.e. primary and secondary sinterings.  The primary sintering is carried out under a reduced pressure and the secondary sintering is conducted under the atmospheric pressure with a sufficient amount of oxygen.  The primary sintering is effected such that the relative density and open porosity of the primarily sintered body are limited to 85% or more and 1% or less, respectively.  Then the voids exiting in the body are removed to a large extent and also the oxidation is sufficiently effected.          Therefore, the finally sintered body has the high density, large surge withstanding capability, and high non-linearity index.
