Patent EP-0113430-A1 (EP)
Inventor: AYCOK DAVID FREDERICK
IPC: C08G65/00
Filed: 1983-12-01
Abstract: The chain length, and therefore, the molecular weight of polyphenylene ether resins prepared by the oxidative coupling of phenols in the presence of a copperamine catalyst is controlled in such a process by additionally including in the reaction mixture an effective amount of a phenolic compound having an acidity constant (K.) the same as, or greater than, phenol. The additional compound can be phenol itself, or various other phenolic compounds not normally suitable as starting materials for the polymerization reaction.

IPC: B60W30/18
Filed: 1983-05-20
Abstract: In a transmission mechanism having an actuator member 98 which is movable to adjust the speed ratio of the transmission, the rate of movement of the actuator member is controlled to provide a desired overall response function. When the speed ratio error is less than a reference value, the rate of movement of the actuator member is controlled as a function of speed ratio, such that the overall rate of change of ratio produces stable response. When the speed ratio error is at or greater than the reference value, the rate of movement of the actuator member is controlled as a function of speed ratio error, such that the overall rate of change of ratio produces fast response consistent with drivability.

Abstract: Selected isotopes of zirconium are separated by irradiating vapor of material consisting of hydrolysis-resistant compounds dicyclopentadienyl zirconium dichloride, dicyclopentadienyl zirconium di-isopropoxide and/or dicyclopentadienyl zirconium di-tert-butoxide with a laser beam tuned to vibration of an excitable band of the component of the compounds including the selected isotope. The component of the material including the excited band is separated from the remainder of the material. Parts for a nuclear reactor are made of zirconium derived from the separated material or from the remainder, whichever has the lower neutron-absorption cross section.

Filed: 1983-12-13
Abstract: In a loader bucket having a back member pivotable on a boom assembly which is pivotable on a tractor and a front member pivotable on the back member, power-operated means for effecting relative pivoting of the members have comprised two hydraulic piston-and-cylinder assemblies disposed at the respective ends of the bucket and fed from a common pressure line so as to work in unison. However, when gripping asymmetrical loads between the members the front member is distorted due to the pressure liquid taking the path of least resistance and thus permitting unequal extension of the piston-and-cylinder assemblies. This problem is minimised by employing a single , central hydraulic piston-and-cylinder assembly (31, 30) connected between a point (13) on the back member and a lug (28) fixed to a torsion bar (23) which interconnects the ends (21) of the front member along its pivot axis. The gripping of asymmetrical loads then twists the torsion bar (23) within its elastic limit.

A slide (7) along the beam (2) closes the anchoring notches (23) of the shaft (32) of the strut to prevent an undesirable folding back of the platform.

Abstract: Bar codes are shown for measurement of volumes of liquids, e.g., the amount of milk collected in a dairy milking operation, and correlation therewith to identification of the source of the liquid, such as a cow. In the preferred embodiment, infrared or laser scanners are used to scan bar codes to provide an input to a computer for correlating the container or the source of liquid with the volume of liquid, whereby complex volume measuring devices and operator measurements can be substantially eliminated. Similar techniques can be used to provide computer input data representing a wide variety of analog inputs; e. g., by providing a bar code scale for juxtaposition to a thermometer, the segments of the code along the scale being selected in accordance with the mercury level at a given temperature, simple analog-to-digital temperature data conversion and input is obtained. Methods and apparatus for providing machine-readability for a number of differing types of analog instrumentation are described.

The utilization coefficient of the light energy is close to one. The automation may be widely extended. Said method may be used for spatial culture.
