Title: Process and apparatus for electroplating
IPC: C25D21/18
Filed: 1971-04-19
Abstract: 1320645 Electro-plating PRODUCTION MACHINERY CORP 19 April 1971 [1 June 1970] 21202/71 Heading C7B In electro-plating e.g. continuously moving steel strip with Cr from an aqueous CrO 3  - SO 4  or SiF 6  plating solution, the fumes generated by the process (from the plating tank and optionally the rinsing tank) are passed, e.g. via gas hood(s) and conduit into a concentrator in intimate liquidvapour contact with at least a portion of the process solution (plating solution and/or overflow rinse water) to dissolve therein chemical values contained in the fumes, and the process solution containing dissolved values is employed in the process. Intimate contact is preferably carried out in a packed bed in the concentrator, wherein the process solution is sprayed upon the packed bed and fumes and passed upwardly therethrough, and gases leaving the bed are passed through a demister above in the concentrator, before exhausting. Overflow rinse water is preferably initially contacted with a cation exchange resin to remove trivalent Cr.

Title: Colour television systems
Inventor: KRAUSE GERHARD
IPC: H04N9/64
Filed: 1969-04-25
Abstract: 1,216,282. Colour television. FERNSEH G.m.b.H. 25 April, 1969 [27 April. 1968], No. 21320/69. Heading H4F. A colour component signal modulated on a carrier is derived from a quadrature modulated colour signal by means of a resonant circuit tuned to the carrier frequency and having a loaded " Q " not greater than the quotient of the carrier frequency and double the maximum modulation frequency in the colour signal and means operative for a time during each cycle of the colour signal to excite the resonant circuit with signals having a mean phase position corresponding to the colour component to be derived. The derived colour component signal may be used in the code conversion of signals between the NTSC and PAL systems, in the recording of television signals and in measuring devices. As shown, Fig. 1, a colour signal F is gated by an electronic switch 2 under the control of a driver 8 synchronized by a carrier frequency signal f applied via a phase shifter 7. The switch 2 is opened during alternate zero crossings of the unwanted component, at which times the desired component is at maximum positive amplitude. The output pulses from switch 2 excite a resonant circuit 4, 5 tuned to the carrier frequency to produce a carrier frequency oscillation modulated with the desired component. The output signal has discontinuities at the peaks at which it is excited, Fig. 2 (not shown) and these may be removed by a lowpass filter or by the low-pass characteristics of subsequent transmission. In the PAL system the colour signal F may be converted into its complex conjugate F* by deriving one component of the signal and adding it with the opposite sign and double the amplitude to the original signal F. In a first embodiment, Fig. 3 (not shown), the addition is achieved by providing the tuned circuit coil (4) with a secondary winding (9) having double the number of turns. The double amplitude component induced across this secondary is added to the original colour signal F which is passed in series through the secondary. In a second embodiment, Fig. 4 (not shown), the output of the tuned circuit is applied to a circuit 13 in which it is subtracted from a signal derived from the input F by means of a resistive potential divider (11, 12) which halves its amplitude. The tuned circuit may be replaced by a ceramic filter or by an active filter of suitable frequency and " Q." The switch may be arranged to open for 180 degrees so that sinusoidal control signals may be used in which case an integrator is inserted between the switch and the resonant circuit. This integrator may comprise a resistor together with the capacitor already present in the tuned circuit, the time constant of the resistor and capacitor being greater than the period of the carrier signal. The switch may be arranged to open for a short time on both positive and negative peaks of the desired component.

Title: Preparation of metallic hydrocarbonyls
Inventor: MERTZWEILLER JOSEPH KERN
IPC: C01G1/04
Filed: 1956-07-10
Abstract: Cobalt hydrocarbonyl is produced by reacting an organic or inorganic cobalt salt, e.g. cobalt formate or acetate, with a gaseous mixture comprising hydrogen and carbon monoxide at a temperature of 90-180 DEG  C. in the presence of an organic solvent. The solvent must be insoluble in water and inert under the reaction conditions.  The solvent may be a primary aliphatic alcohol or aldehyde containing at least 4 carbon atoms, e.g. iso-octyl alcohol or aldehyde, or a crude mixture obtained by decobalting oxo products or by hydrogenation of the product of a hydroformylation reaction.  The reaction may take place in the presence or absence of water.  In the former case an aqueous solution of the (metal) hydrocarbonyl is produced directly, while in the latter case the hydrocarbonyl may be extracted from the organic solvent by the subsequent addition of water.  An aqueous solution of a cobalt salt containing 2-5 wt. % of cobalt and 10-100% of solvent based on the aqueous solution may be employed. The reaction may be carried out at a pressure of 1000-4000 p.s.i.g., and a contact time of 0.5-6 hours.  The hydrogen-carbon monoxide mixture may be employed in a 10-100 fold stoichiometric excess with respect to cobalt.  The hydrogencarbon monoxide ratio may be 0.5-4 to 1, preferably 1 to 1.  According to the embodiment illustrated (Figure not shown), an aqueous solution of a cobalt salt is passed downwards through a tower in counter-current to synthesis gas and recycled solvent.  The reaction may be allowed to proceed to a limited extent such that the unreacted cobalt salt is at least stoichiometrically equivalent to the hydrocarbonyl produced, so as to produce a salt of the hydrocarbonyl.  Cobalt carbonyl may be produced by treating an aqueous solution of the hydrocarbonyl under acidic conditions with air.

Title: Improvements in and relating to feelers for copying machines
Inventor: SCHMIDT WOLFGANG
IPC: B23Q35/121
Filed: 1952-09-01
Abstract: 759,699. Electric follow-up systems. SOC. AUTOMATA. Sept. 1, 1952, No. 22002/52. Class 40(1) The deflections of the feeler in a copying machine are translated in amplified form to a forked lever which controls the movements of the co-ordinate drives of both the pattern and work, through contacts, actuated in turn at successively greater deflections of the feeler, controlling at least four relays singly or in combination. As shown, the free end 21 of a lever 10, Fig. 2, moved vertically upwards in accordance with the deflection of the feeler 2 from its neutral position, as disclosed in Specification 759,697 carries two adjustable blocks 22, 23 which deflect respective blade springs 31, 28, Fig. 5. The blade springs are anchored at their ends and each co-acts with four pairs of contacts adjustable as at 36, 37, 38. In the neutral, i.e. undeflected position of the feeler, relay R<SP>1</SP> only of the relays R<SP>1</SP>...R<SP>4</SP> is de-energized, whereby the "north" coil Ka is energized to drive the feeler towards the pattern. As the feeler engages and is deflected by the pattern, the contacts II... VII are actuated respectively at sequentially increased feeler deflections, to deenergize the North, South, West and East relays R<SP>1</SP>...R<SP>4</SP> singly or in pairs, to operate the corresponding drive motor clutches Ka...Kd so that the feeler follows the pattern outline. A lamp 35 is lighted over contact L while the feeler contacts the pattern, and a "safety" contact S opens upon excessive deflection of the feeler to deenergize a coil 34 to open the main switch H and stop the motor feeds. In another embodiment, Fig. 6, the relays R<SP>1</SP>...R<SP>4</SP> are connected to respective contact blades 41...44 of a fixed commutator 47, a carbon brush 45 carried by the fork-end engaging the contact 41 in the neutral position of the feeler, and sweeping over the contacts successively as the feeler deflection increases. The brush is wide enough to contact two contacts simultaneously so that the clutch coils K<SP>1</SP>...K<SP>4</SP> are energized singly or in pairs to produce the appropriate longitudinal, transverse or diagonal feed of the pattern. Modifications. Coarse and fine working may be effected by providing on the fork two brushes B1, B2, Fig. 7, co-acting with respective commutators of differing physical dimensions. Switching from coarse to fine may be effected manually by throwing a switch U or automatically by a time relay which produces an impulse to effect the change whenever a rapid change in feeler deflection takes place. Coarse, fine and very fine working may be effected by a further brush and series of contacts. External or internal copying may be effected dependent on the inter-connections of the coils K<SP>1</SP>...K<SP>4</SP>. Specifications 759,698 and 759,700 also are referred to.
