Abstract: 1371795 Cobalt carbonyl; iron carbonyl cobaltate DAICEL Ltd 13 Sept 1971 [14 Sept 1970 (2)] 42557/71 Heading C1A [Also in Division C2] Cobalt is recovered as cobalt carbonyl from the product of an "oxo" reaction in which cobalt is used as the catalyst by treating the product with a material containing iron, which material is selected from metallic iron, iron oxides, and hydroxides and iron salts of weak acids, the contact taking place in the presence of water, carbon monoxide and hydrogen whereby the cobalt moves into the aqueous phase as an iron carbonyl cobaltate, this aqueous phase is separated from the organic phase, and the cobalt carbonyl regenerated by treating the aqueous phase with a mineral or organic acid. If desired, the carbonyl may be obtained as the hydrocarbonyl by passing an inert gas through the aqueous phase, and dissolving the hydrocarbonyl thereby carried away by treating the gas with an organic solvent or "oxo" reactant, or the carbonyl may be extracted by a suitable organic liquid. The solution of carbonyl so obtained may be recycled as catalyst to the oxo reaction. The iron containing material may be a ferrous hydroxide containing mixture obtained by mixing an aqueous soln. of a ferrous salt of a strong acid with an alkaline metal or alkaline earth metal hydroxide. The iron-containing material may also be wrought iron, Raney iron, reduced iron, undeveloped Raney iron, or the carbonates, bicarbonates, sulphide, naphthenate, lactate or acetylacetonate of iron. Preferably the amount of iron used is at least equivalent to the amount of cobalt in the starting mixture. The amount of water used may be from 10% to 500% by volume based on the volume of the initial oxo product. The extraction may be carried out at a pressure of 10-500 kg./cm.<2> gauge, preferably 50 to 300 kg./cm.<2> gauge of a mixed gas of CO and H2 in a ratio of 1 : 1 to 1 : 2 at a temp. of 60-200 C., preferably 100 to 170 C. The mineral acid used may be sulphuric acid, hydrochloric acid or phosphoric acid, and the organic acid may be trichloroacetic acid or p-toluene sulphonic acid. In Example 1, butyraldehyde is obtained by using propylene as reactant and dicobalt octacarbonyl as catalyst in an "oxo-reaction". Cobalt is removed from the productusing the above process.

Filed: 1972-09-18
Abstract: 1384818 Semi-conductor devices PLESSEY CO Ltd 8 Aug 1973 [18 Sept 1972] 43222/72 Heading H1K A plurality of capacitative storage cells are formed in a substrate 1 of a given conductivity type by diffused regions 2 of the opposite conductivity type and overlying capacitative electrodes 5. A magnetic field or an electric field if applied to the substrate to provide a bias such that minority carriers injected from one diffusion move to a particular neighbouring diffusion. The arrangement shown is a shift register (which in practice would have more storage cells) in which the bias is provided by a voltage source connected across contacts 7, 8. Information fed to one of the terminals 6 is shifted by clock pulses applied alternately to electrodes 5 such that when the potential applied to an electrode 5 is high and stored information is non-zero the corresponding PN junction 3 becomes forward biased and injects carriers in a number equivalent to the stored information into the substrate and these move in the bias field to be collected by the next diffusion, the electrode 5 of which is at that time at low potential. Losses in the substrate are reduced by the carrierreflecting NN<+> junction. The stored information, which may be in digital or analogue form, appears at the other terminal 6 and may be presented in electrical or optical form. Radiation could instead be used to supply the input information. Systems employing 3 clock pulse sources could replace the two pulse systems described, and a rectangular matrix of cells could use two electric fields, or one electric and one magnetic, to provide the perpendicular biases for the rows and columns. Fig. 5 shows a schematic arrangement for logic circuitry with three "first" cells A and a single "final" cell C. Stored charge from the A cells may be moved simultaneously or sequentially to the C cell. The logic operation performed depends on the relative capacitances of the cells. If all four cells are equivalent, the device is a 3 input OR gate; if cell C has twice the capacitance of each A cell the device is a 2-out-of-3-gate; and if cell C has three times the capacitance of each A cell, the device is an AND gate.

Filed: 1976-10-19
Abstract: 1511767 Automatic exchange systems INTERNATIONAL STANDARD ELECTRIC CORP 19 Oct 1976 [25 Oct 1975] 43322/76 Heading H4K A circuit arrangement for monitoring the operating condition of a telephone subscriber line a, b, for connecting ringing current, through a generator G and for ring tripping, through ringing relay R and its command circuit is not provided with a separate detector for detecting the closed-loop condition during ringing. A detector I1 detects the closed-loop condition and a detector I2 in cooperation with I1 detects the depression of a grounding button; the output of both detectors are connected to a central control unit ST and the output of detector I1 is also connected to the control circuit of the ringing relay R, to suppress a ringing command when a closed loop condition is detected. The inputs to detectors I1 and I2 are connected to the line a, b as shown. Operation: Quiescent condition.-No supply current flows and the outputs of detectors I1, I2 are in the OFF state. Close-loop condition.-Removal of the handset causes supply current to flow in the subscribers loop; outputs of detectors I1, I2 in the ON state. Depressed - grounding - button - condition.- Operation of the grounding button causes current to flow in wire a through resistor W1 and resistor W1<SP>1</SP> is short circuited. The output of detector I2 is in its OFF state. The central control unit ST determines from the previous state of I1 whether the button was operated from a loop closed or loop open condition. Ringing condition.-Relay R is operated by control unit ST through h; ringing current flows from generator 6, via line and capacitor Cl to ground and supply U. Dl serves to divert positive peaks of ringing current. D2 is off and the outputs of I1, I2 are in the OFF state; hence Zener diode Z is cut off. Closed-loop condition during ringing.-When the subscriber lifts his handset a direct current flows in the loop superimposed on the alternating current. Diode D2 conducts to enable I1 whose output renders zener Z conductive so that transistor T is turned OFF thereby releasing relay R. While rl, r2 are switching back capacitor C maintains I1 enabled. Control unit ST responds to remove the signal on h.
