Abstract: 1411293 Regeneration of solutions by electrodialysis DART INDUSTRIES Inc 14 Nov 1972 [19 Jan 1972] 52495/72 Heading C7B In an electrodialysis process for regenerating an aqueous acid solution contaminated by metal ions, the solution is placed in one compartment of an electrodialysis cell, under the influence of the electrodes metal ions pass into a second aqueous solution in a second dialysis compartment through a membrane. Plating out of the metal is prevented in this compartment by choice of electrode material, the conditions of operation or by separating the solution from the cathode by a membrane. The solution containing the metal ions is then removed from the second dialysis compartment and passed to an external system where the metal is removed by plating, cationic exchange, electrodialysis or precipitation of its salt. The regenerated solution may be reused. The cathode may be T: Pt, platinized Pt or platinized graphite i.e. electrodes having low H 2  overpotential so that H2 is deposited in preference to the metal. In Fig. 4 the chromic acid etching solution containing copper ions is pumped from holding tank D through anolyte compartment A via line 21. Copper ions pass through the cation membrane and accumulate in the central compartment B. The solution in B is passed to holding tank I and the copper is removed either by plating in tank F or by cationic exchange in column H. The removal of Cu, Zn, Ni, Au, Ag, Al and Ti are mentioned.

Abstract: 1,200,119. Boring. KONGSBERG VAPENFABRIKKAS. 24 Nov., 1967 [29 Nov., 1966], No. 53483/67. Heading B3C. A bore having a contour P n-1 , P b , P n , P n+1  is produced in a workpiece, and if the tool breaks at point Pb for example, it is retracted along, or parallel to, the contour, to a point P n , and thence to a position P e , where the tool is changed. The tool movements are controlled by a punched tape which has a data set P n-1 - P n  representing the curved contour element and auxiliary data sets P n-1 -P h , P h -P e , and P n -P n+1  may be provided, which are used only if the tool breaks during machining of the contour, for retracting the tool from point P n-1  to P e . After replacing the tool it is moved in the cutting direction, which movement is controlled by the data sets. The latter may be produced during normal machining but they are only read in if the operator switches over his control equipment to position " tool breakage." The contour sets and auxiliary sets may be provided on different carriers.

[Also in Divisions G3 and H4] Associated with a disc 10 on which a television signal is recorded magnetically, or, preferably, optically in a spiral track, is a motor 12 which drives the disc at one-turn-per-frame and a disc 14 with black-and-white patches, Fig. 1A, which passes a scanning means 30, 31 at line frequency. Where the camera 20 is local to the recorder, Fig. 1, circuitry 32, 33, 34 arranges the line time-base in the camera to be driven at a rate such that despite slow speed variations in the motor 12, the line synch. pulses are recorded on the disc 10 in radial lines, so that on playback adjacent tracks contain identically phased synch. pulses and near-identical video signals enabling the radial drive accuracy of the head 16 to be low. In embodiments where the incoming signal has its own pulse frequency (broadcasting, particularly foreign from non-synchronized mains), the signal from 14 is compared with the pulses in the incoming signal to affect servo means. In one variation, Fig. 3 (not shown, but described in Divisions G2-G3) the motor 12 has a movable stator driven by a servo motor. In another variation, Fig. 4 (not shown), the signal is fed to the head 16 via a variable delay line whose delay is servo-controlled to place each line of signal in alignment with the corresponding line of the previous frame.

E. T. switch 4 to a D.C. meter 5; the core also developing by electrostatic induction a voltage, in phase with the load voltage, for controlling the switch 4. The average current through the meter is proportional to the line current times the cosine of the phase angle between the line current and line voltage and since the line voltage is constant the meter can be calibrated to indicate power. Any necessary phase adjustment can be obtained by capacitor 9 and a quasi ground connection 6 is obtained via the instrument casing and the operator. In a second arrangement, Fig. 2 (not shown), the F. E. T. switch is replaced by a balanced modulator, and the electrostatically induced voltage is amplified by a circuit which obtains its power from a second winding on the transformer core.

Abstract: 1,212,362. Printed circuits. PHOTO-CIRCUITS CORP. 28 Nov., 1967 [1 Dec., 1966], No. 53982/67. Heading H1R. A printed circuit having metallized holes is formed by coating exposed conductor lines on a catalytic base with a permanent insulating mask, forming holes through the mask and base and electrolessly depositing metal on the walls of the holes. In the embodiment of Fig. 10 conductors 14 are formed from a metal-clad catalytic base by a print and etch method and after removal of the etch resist 15 both sides of the base are coated with an insulating non-catalytic permanent mask 17. Holes 22 are then formed through the panel which is then subjected to an electroless plating bath to form deposit 24 on the hole walls. The insulating mask 17 may be deposited so as to leave exposed lands around the holes which are coated with metal during the subsequent electroless plating process, Fig. 12 (not shown). During the plating process the wall coating 24 grows vertically as well as horizontally over the insulating mask so that by choosing the appropriate thickness of the mask the wall coating may or may not creep to the surface of the mask to form eyelets, Figs. 13, 13A, 13B, 13C (not shown). The process shown in Fig. 10 may be extended to form multilayer circuit boards by interspersing catalytic bases in a stack of bases carrying circuit conductors, masking the exposed conductors and forming the metal-lined holes as described above, Fig. 12 (not shown). In the embodiment of Fig. 15, conductors 1202 are formed by a print and etch process on both sides of catalytic base 1000. Catalytic permanent insulating masks 1610 are then deposited over the conductors 1202 after which holes 1500 are provided and metal deposit 1501 formed by an electroless plating process. After superimposing removable insulating masks 2000 on the top and bottom surfaces of the board, the metal deposit 1501 on the hole walls is built up, 2200, by electroplating. Mask 2000 is finally stripped off. In a further embodiment, Fig. 16 (not shown), printed conductors on both sides of a catalytic base are coated with a catalytic insulating layer on which is superimposed a non-catalytic adhesive layer. Holes are formed and electrolessly plated as previously.

A bumper bar 38 is supported by a telescopic strut 24 which absorbs low energy impact. The strut comprises a cylinder 26 slidable with a cylinder 28 fixed to a frame member 14; cylinder 24 is closed by an apertured piston defining with cylinder 28 a first hydraulic chamber and contains a gas loaded piston which defines with the apertured piston a second hydraulic chamber. A metering rod fixed to the closed end of cylinder 28 passes through the apertured piston. On impact cylinder 24 moves rearwardly and fluid flows across the piston, the flow being progressively reduced by the metering rod. The frame member 14 has corrugated portions 20, 22 which allow collapse of the frame at higher impact energies. A pressurized gas housing 50 is formed in the frame member and is closed by a rupturable disc 64 which also seals a connection 68 to an inflatable cushion in the passenger compartment. A piercing rod 76 attached to a wall 54 of the frame member destroys the disc 64 if the impact energy is sufficient to collapse the frame member to a predetermined extent.
