Abstract: TITLE OF THE INVENTION           PROCESS FOR PRODUCING 1,4-GLYCOL DIESTER     ABSTRACT OF THE DISCLOSURE          A process is described for producing 1,4-glycol diesters which comprises reacting butadiene, acetic acid and oxygen or an oxygen-containing gas in the presence of a palladium catalyst.  The 1,4-glycol diesters are separated from the reaction mixture and, according to the novel feature, the residual glycol diester isomers in the reaction mixture are subjected to heat treatment to decompose the glycol di-ester isomers, forming butadiene and/or acetic acid, which is then recycled as part of the butadiene and acetic feed stocks.          This results in an improved process efficiency.

Abstract: ABSTRACT OF THE DISCLOSURE         A grain moisture meter comprises a half wave pulse oscillator with pulses connecting to the outer shell of a grain container.  Pulses pass through the grain and through a central electrode and the signals are amplified and fed to a meter to read the moisture content.  A thermistor is in circuit to ad-just for variations in temperature of the grain.  The device can be adjusted to test grain by three methods.  Firstly, it can give an indication of dryness, toughness and dampness to a farmer in the field when combining.  Secondly, by use of charts or graphs, it can be used to identify each point on the scale giving an accurate determination of the moisture content of any grade above number four grade and thirdly, by the use of other charts or graphs, accurate readings of any grain grade can be ascertained.

Abstract: QUARTUM INTERFERENCE JOSEPHSON LOGIC DEVICES                 Abstract of the Disclosure A quantum interference Josephson junction logic device is disclosed which comprises three or more junctions connected in parallel which are capable of carrying Josephson current and includes means integral with at least one of the junctions for carrying a larger maximum Josephson current than the remaining junctions.  The spacing between the lobes of the thres-hold curve is increased over that of a two junction interferometer result-ing in an increased operating region in which logic circuits switch to the voltage state.  Good current gain with large lobe separation may be ob-tained if the two outer junctions having a zero field threshold current, Io, are connected via an inductance, L, to the center junction with a maxi-mum Josephson current, 21o.  Apart from the gain enhancement due to in-creased current in at least one of the junctions and that due to the com-bination of increased current in at least one of the junctions and the symmetrical dual feed, increased gain and operating range can be achieved using the symmetrical dual feed in combination with interferometer arrange-ments where the maximum Josephson current in all the junctions thereof is the same.
