Abstract: 1,227,613. Measuring moisture content. Measuring capacitive parameters. INDUSTRIAL NUCLEONICS CORP. April 9, 1968 [April 27, 1967], No.17079/68. Headings G1N and G1U. In apparatus for measuring the dielectric constant and hence the moisture content of a plurality of paper webs using a plurality of capacitive probes having a common control station, adjustment of each of the measuring circuits to give zero output in the absence of a web is facilitated by the provision of a respective voltage controlled variable semi-conductor capacitor connected in series with the probe capacitor and two 180 degrees out of phase A. C . voltage, the variable semi-conductor capacitor being controlled by an adjustable D.C. source at the control station. As shown in Fig.2, a probe 12 is connected to the control station 19 by a cable 18. The measuring circuit comprises a capacitive probe 37 having two active electrodes 36, 39, the fringe field of which depends on the moisture content of the web 11. Electrode 36 is energized with A.C. from two oscillators 31, 32 of different frequencies. Electrode 39 is connected via output lead 47 to band pass filter 48, 49, detectors 51, 52 and a ratio forming circuit 53. The capacitance of varactor diode 42 is controlled by adjusting the position of slider 23. Because the capacitance of varactor diode 42 is usually about five times the capacitance between plates 36, 39, capacitine voltage divider circuits may be employed to reduce the effective capacitance of the varactor diode, Figs.3 and 5 (not shown). To reduce the effect of the alternating voltage on the capacitance of the varactor diode, two varactor diodes may be connected in series back to back relation with respect to the A.C. sources and in parallel relation with respect to the D.C. source, Fig.4 (not shown). A transformer may be used instead of inverter 41, Fig.5 (not shown). The probes may be driven to and fro to scan the width of the webs.

Abstract: 1,228,286. Manufacture of printed circuit boards. GRAPHIC ELECTRONICS Inc. 18 Nov., 1969 [9 Jan., 1969], No. 56464/69. Heading H1R. A printed circuit board is produced directly from an original copy on an engraving machine of the type in which the copy, mounted on a first cylinder, is scanned photoelectrically to control a V-shaped stylus which removes a conductive metal surface from a thin laminate wrapped round a second synchronously driven cylinder. An additional layer of backing material may be secured with adhesive to the back of a completed circuit board to increase its thickness and rigidity. A coating of solder may be applied, e.g. by electroplating, to the surface of the conductive metal layer prior to the cutting operation to facilitate the subsequent soldering of components thereto. The cutting stylus is manufactured from tungsten carbide. The engraving machine has a reversing switch to control the cutter head so that printed circuit boards may be made either from positive or negative original copies.

A quarter of meat 5 is de-boned by supporting its thick side on a table 32, forming part of a first cutting unit 2 engaging its thin side in a pincer device 161 of a second cutting unit 3, such that its spinal column 4 overhangs the edge of the table, moving a rotating cylindrical cutter 11 upwardly into engagement with the spinal column to grind it away while the meat is firmly held by retractable gripping devices 34, 55, 60; after completion of grinding, transferring the quarter by rotation of the pincer device to the underside of a feeding and supporting arrangement 131, 132, 137 against which it is held by a retractable pressure roller 141, and grinding away the ribs by rotating milling cylinder 124 while feeding the quarter towards the milling cylinder and away from the pincer device by driving the feeding and pressure rollers 131, 132 and 141. The support 137 is a fixed guide to determine the direction of movement of the leading edges of the ribs. In the embodiment of Figs. 1 and 3, the first cutting unit comprises a carriage whereby the cutter 11 and gripping devices 34, 55, 60 are movable towards and away from the pincer device. Piston- and-cylinder jacks 48, 57, 73 and 95 are mounted on the carriage for retracting and projecting the gripping devices 34, 55, 60 and the cutter 11, respectively, while a further pair of jacks 146 are pivotally mounted on the fixed frame 1 for elevating and lowering the pressure cylinder 141. The pincer device comprises jaws 162, 163 pivotally connected by a shaft 164 and operated by a pair of toggle links 173 actuated by a jack 167. The jaws extend over substantially the full width of the machine. Rotation of the pincer device is effected by an electric motor (174, Fig. 2, not shown) which is geared to the shaft 164. The rollers 131, 132 and 141, and the milling cylinder 124, are driven by a motor 127 through a gear box 133 and belt or chain drives 128, 134, 135 and 155, whilst a motor 21 on the carriage 2 drives the cutter 11 through gear box 24 and belts 107, 112. In a second embodiment (Fig. 4, not shown), the first cutting unit (2) is fixed, whilst the second cutting unit (3) comprises a carriage running on rails (182) on the fixed frame (1). In a third embodiment (Figs. 5-7, not shown) both cutting units are fixed but the pincer device is modified so that it can not only be rotated but also given a translational movement towards and away from the cutting unit (2), a further jack being provided for this purpose.

Abstract: 1,256,586. Process for recovering quinone compounds and the production of hydrogen paroxide. LAPORTE INDUSTRIES Ltd. 13 March, 1970 [18 March, 1969], No. 14042/69. Heading C2C. [Also in Division C1] The invention relates to a process for the recovery of a quinone from a working solution comprising one or more suitable quinone compounds dissolved in a solvent system, the solvent system comprising a quinol-dissolving constituent and a quinone dissolving constituent and the working solution having a content of non- regenerable by-products as a result of the use of the working solution in a continuous process for the production of hydrogen peroxide comprising treating the working solution so as to convert the quinone compound therein into an ion exchangeable form, e.g. by hydrogenation, contacting the working solution, containing the ion exchangeable form of the quinone compound, with a macroreticular ion exchange resin having an ionic form which will allow ion exchange of the ion exchangeable form of the quinone compound on to the ion exchange resin, separating the ion exchange resin from the working solution and treating the ion exchange resin so as to recover quinone compound therefrom. Hydrogen peroxide may be prepared by subjecting the quinone compounds in a solvent system to a series of cycles of process steps each cycle including catalytic hydrogenation, which results in the formation of a quinol, oxidation which results in the formation of a quinone and hydrogen peroxide and aqueous extraction of a hydrogen peroxide.

A folded network as claimed in claim 1 of parent Specification, which is such that a connection is set up over as few stages of the network as the spacing of the inlets to be connected allows, is adapted for four-wire working and avoids the reversal of pairs by switching in junctors, in order that each send pair should be connected to an outgoing receive pair and each receive pair to an outgoing send pair, and achieves this by providing within each group of circuits terminated on the network some circuits with their send pairs and receive pairs terminated reversely with respect to the others in the group. As shown, a connection between a line Lxal of subgroup XA of group X, if directed to a group Y, must be terminated on a line of subgroup YB such as Lyb1; the order of connection of the pairs in the B subgroups being reversed as compared with the pairs in the A subgroups. Connections between lines of like subgroups, such as lines Lxb1 and Lyb1, can be effected by setting up two connections in tandem over network K with the inclusion of a reversing junction such as R. The network K employs multiswitches, by which is meant relay crosspoint, crossbar, or crossed-coil switches.

In operation, the coil supporting mandrel 48 is moved along a slot 54 in base 18 of the forming station 10 by a hydraulically operated carriage 28 so that the coil slides off the base 18 on to base 94 of the cradle 88. Pivoted fingers 98a and 98b are then closed around and above the coil so as to completely support the coil. The mandrel 48 is then lowered and the cradle 88 pivoted to the horizontal position about pivot 90. On reaching the horizontal position, the cradle 88 is moved by the rack and pinion actuated carriage 72 towards the carrier 12 so that the coil is axially inserted over the arm 12a. Finally the rails 76 are pivoted downwardly about pivot 62 so as to rest the coil on the arm 12a.
