Title: Preparation of furan compounds and catalyst system
Inventor: GARNETT DONALD IRWIN
IPC: B01J27/06
Filed: 1979-08-21
Granted: 1984-12-20
Abstract: A process for preparing a furan compound by the catalytic oxidation of a diolefin such as butadiene or a halo-substituted alkene is provided. ln this process, the starting material is contacted with an aqueous medium having a pH less than about 2 containing (1) iodide ion, (2) a mixture of cuprous and cupric ions, and (3) a solubilizing agent for cuprous ion such as an alkali metal halide. Optionally, an oxygen-containing gas such as air can also be contacted with the aqueous medium. In one embodiment, the starting material is contacted with an aqueous solution of the aforesaid ingredients in one reaction zone to prepare furan and a portion of the solution is passed to a second reaction zone where cuprous ion is oxidized to cupric ion with air and then the air-treated solution returned to the first reaction zone.

Title: Device for feeding a conveyor with flat objects in shingled formation, in particular printed products
Inventor: REIST WALTER
IPC: B65H29/66
Filed: 1980-01-14
Granted: 1982-11-04
Abstract: Attached to revolving traction elements are a number of equidistantly arranged entrainment members having impact surfaces at their leading edges. The impact surfaces engage at trailing edges of the printed products arriving in an imbricated product stream. Between the traction elements there is arranged a suction head connected by means of a connection line or conduit with a negative pressure source. The suction head fixedly retains the printed products moving therepast or delays their forward movement until the engaged printed product can be entrained by one of the entrainment members. Due to the holding back of each second printed product each entrainment member infeeds two superimposed printed products to the individual grippers of a transport device. Since each gripper conveys away two printed products the transport device can be driven at a lower velocity that the infeed velocity of the imbricated product stream, which, among other things, affords quieter travel and reduced wear of the transport device.

Title: Method for circumferentially binding a coil having an axis extending horizontally and binding apparatus for use in the method
Inventor: FELDMANN PETRUS HUBERTUS MARIA
IPC: B65B13/08
Filed: 1981-02-24
Granted: 1984-09-06
Abstract: To avoid the need for awkward and possibly hazardous movements by an operator when binding a large coil, e.g. of steel strip, a binding apparatus has an arm 13 swingable about an axis 15 by cylinder 14 and carrying at its end a binding head 17. In use, the arm 13 is brought into position D where the binding element is inserted into the head which holds it while the arm 13 is then swung to the position C. The head 17 then operates to pass the binding strip through the head so that its end reaches the position E where it can conveniently be tied by the operator.

Title: Passive fiber optic multiplexer
Inventor: SHAW HERBERT JOHN
IPC: G02B6/28
Filed: 1982-11-04
Granted: 1987-04-02
Abstract: A passive, frequency selective, fiber optic multiplexer, comprises a directional coupler in which a pair of single mode optical fibers are accurately positioned to provide evanescent field coupling, typically by polishing a portion of the cladding from each of said fibers to place the respective cores of said fibers within the evanescent field of light in the other fiber. The coupling efficiency of a coupler constructed in this manner is wavelength dependent, and provides over-coupling, that is, the capability of transferring light, virtually entirely, back and forth between the fibers within the coupler. The wavelength dependent nature of the evanescent field coupling permits multiplexing, specifically between a pair of wavelengths, one of which is coupled in its entirety from a first fiber to a second fiber, and the other of which is essentially uncoupled. By increasing the number of total transfers of the light signals between the pair of fibers, the frequency resolution of the multiplexer may be optimized for light signals of virtually any frequency separation.

Title: Stabilized fiber optic sensor
Inventor: SHAW HERBERT JOHN
IPC: G01H9/00
Filed: 1983-09-27
Granted: 1989-10-05
Abstract: A fiber optic sensor comprises a length of optical fiber (10), forming a loop (40), and a fiber optic directional coupler (20) for optically closing the loop (14). The loop (14) and coupler (20) form a resonant cavity for light circulating therethrough. A PZT cylinder (118), about which the fiber loop (14) is wrapped, is utilized to control the total round trip phase delay of the circulating light, and thus, control the intensity of the optical output signal W<sub>o</sub>. The phase delay is adjusted to a point Z where the optical output signal W<sub>e</sub> is at maximum sensitivity to changes in phase. When the fiber loop (14) is exposed to, e.g., acoustic waves, the loop length changes correspondingly, thereby causing the phase delay, and thus, the optical output signal W<sub>o</sub> to vary. By detecting variations in output signal intensity, the frequency and intensity of the acoustic waves may be determined. The sensor also includes a feedback system for stabilizing the fiber loop (14) against low frequency thermal drift.

Title: Electrode system for the measurement of corrosion rate
Inventor: VIDEM KETIL
IPC: G01N17/00
Filed: 1984-11-02
Granted: 1989-09-28
Abstract: An electrode system (E) for the measurement of corrosion rate of metal subjected to corrosion in watery medium comprises two electrodes (A+R, M) of the respective metal, which are disposed in spaced relationship to be submerged into the watery medium and convey electric current through the same. The metal electrodes (A+R, M) are disposed on the interior surface of a ring (I) of electrically insulating material with their active electrode surfaces spaced apart and preferably flush with and having the same curvature as the interior surface of the ring (I). An outer annular flange (Y) of high strength material is mounted around and rigidly secured to the inner ring (I) of insulating material. The outer annular flange and the inner ring as well as the metal electrodes are then configurated and dimensioned to fit in and be liquid-tight maintained between flanges on pipe sections (S1, S2) which are joined together to form a pipeline for the through-flow of said watery medium. At least one of the electrodes (A+R) is preferably subdivided into a working electrode and a reference electrode (R), which are spaced far less apart than said distance between the two electrode sufaces. If the voltage drop between the reference electrode and the working electrode is measured when a prescribed current is flowing between the working electrode and the counter electrode in the watery medium, the polarization resistance of the corrosive reaction on the working electrode may be determined with high accuracy.
