Abstract: Aldehydes and alcohols are prepared by reacting an olefinic compound having n carbon atoms with carbon monoxide and hydrogen in the presence of a carbonylation catalyst to produce products including aldehydes and alcohols having n + 1 carbon atoms, dimerizing the products at least in part in the presence of a dimerization catalyst to produce oxidation products having 2n + 2 carbon atoms and higher boiling oxygenated products, separating the oxygenated products having n + 1 and 2n + 2 carbon atoms from the higher boiling products, subjecting the latter to steam distillation in the presence of aqueous acid, and recovering from the resultant steam distillate aldehydes and alcohols having n + 1 and 2n + 2 carbon atoms. The residue from the steam distillation may be separated into an organic phase and an aqueous phase and the former steam distilled in the presence of an aqueous base to give a steam distillate from which further quantities of aldehydes and alcohols containing n + 1 and 2n + 2 carbon atoms may be recovered.  Suitable aqueous acids are, for example, sulphuric, nitric, phosphoric and hydrochloric acids and suitable bases are alkali metal hydroxides. The carbonylation and dimerization may be carried out in separate steps or combined in a single step.  The preferred carbonylation catalysts are organic acid salts of cobalt and the suitable dimerization catalysts are C6-C18 fatty acid salts of zinc, magnesium, lead, beryllium or barium, the zinc salts being preferred. The starting olefines are preferably those containing 3-20 carbon atoms.

Abstract: 1,036,190. Discharge lamps. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. Nov. 18, 1964 [Nov. 25, 1963], No. 46921/64. Heading H1D. In an ultra-violet source for a spectrograph, the discharge between the main electrodes is initiated by a spark passing across the surface of a solid dielectric material which separates two auxiliary electrodes, a first capacitor being discharged across the auxiliary electrodes to produce the discharge of a second capacitor across the main electrodes. Metal vessel 1 acts as the earthed main electrode, and is joined by the alumina, silica or P.T.F.E. tube 4 to the anode 3, which is surrounded by the coaxial extension 12 of the vessel 1. Vessel 1 has an evacuation port 2 and an aperture 14 for correction of the spectrograph 13, and houses the auxiliary electrodes 5 and 6 which are spaced apart by a silica, alumina, or mica strip 7. Contamination resulting from vaporization of the material of tube 4 is reduced by protecting anode 3 with a tantalum cap 5, and aperture 14 by aluminium discs 16. A rotary switch successively and repetitively makes connections (Fig. 2, not shown) to charge up a first and then a second capacitor bank from a 30 kv. source, and then to discharge the second bank across electrodes 5 and 6 to produce a sliding spark across the surface of dielectric 7 which initiates the discharge of the first bank across electr o des 1 and 3. In a modified supply arrangement, the controlled repetitive discharge across electrodes 5 and 6 is produced by a pulse generator and thyratron.

Title: Look-ahead control for operation of program loops
Inventor: WATSON WILLIAM JOSEPH
IPC: G06F9/38
Filed: 1969-09-26
Abstract: 1293547 Digital computers; instruction look ahead TEXAS INSTRUMENTS Inc 26 Sept 1969 [4 Dec 1968] 47457/69 Heading G4A An instruction look ahead system for a digital computer is described. The computer (Fig. 1, not shown).-This includes a central processing unit, a peripheral processing unit, thin film stores, magnetic tape, discs and drums, a card reader, a punch unit, keyboards, cathode-ray tubes, read only microprogrammes and memory protection. It is further described in Specification 1,278,101. The look ahead unit.-Instructions pass in parallel in blocks of eight from memory 18 to instruction processing means 128, 129, 215, 216 where two blocks are held whence they are passed serially to registers 221, 224, 229 and thence to the memory buffer 100 and arithmetic unit 101 under control of a third decoder 218. The third decoder responds to the last three digits in the present address register which holds the address of the instruction being executed. A preliminary (first) decoder 226 senses look ahead instructions (i.e. those indicating a conditional branch a number of instructions ahead, see Table I in description) to set an index in a counter 258 which is decremented thereafter for each instruction executed up to a predetermined count representing the number of instructions between the look ahead instruction and the conditional branch. A second decoder 234 responds to a conditional branch to transfer the address of the look ahead instruction from a branch address register 274 to a look ahead address register 276. This causes the previously executed instructions to be repeated for a programme loop. If, however, the condition is satisfied means are provided for resetting the look ahead system, the computer processes instructions downstream of the conditional branch instruction, and the look ahead system operates on these. Details.-The decoder 226 detects a look ahead instruction at level 1 of the 3 level instruction pipeline and the decoder 234 decodes the presence of a conditional branch at level 2 which prevents further incrementing of present address register 244 and permits transfer of an effective address thereto from register 232, the present address going to register 232. This transfer occurs for each loop until the condition has been satisfied.

Abstract: 1281342 Monitoring fluids photo-electrically ENGLISH CLAYS LOVERING POCHIN & CO Ltd 8 Oct 1969 [9 Oct 1968] 47946/68 Heading G1A The concentration of solids in suspension in a fluid is measured by comparing the signals produced by two photo-cells one of which is illuminated directly by a source and the other illuminated by light from the same source reflected from the suspended particles this other photo-cell being embedded in a window of a housing enclosing the photo-cells and light source. The lamps 24 and two photo-resistive cells 25, 26 are housed in unit 5 which is fixed in one wall of a cylindrical measuring chamber. Lamp 24 is supplied via head 31 from a stabilized power supply and illuminates photo-cell 26 through neutral colour filter 27. The photo-cells are embedded in the epoxy resin window 22 and are connected in a bridge circuit energized from the same power supply. Light from the lamp passes through window 22 and is reflected by the suspended particles in chamber 1. The chamber, which is preferably cylindrical, has an inlet port 2 and outlet port 3 and has the wall 7 opposite the unit provided with a reflecting surface. The suspension may continuously pass through chamber 1 or alternatively the chamber is filled for the duration of the measurement and then emptied and refilled. The apparatus is calibrated by measuring the reflection from wall 7 when the chamber is filled with water. The bridge circuit output signal can be arranged to give an indication of the concentration either as a direct reading or on a recorder. A visual or audible alarm can be given if the concentration reaches a high level or valves can be operated to provide corrective action. In a practical embodiment the housing may be secured in the wall of a pipe, Fig. 5 (not shown), to monitor the flow of liquid which is returned for further treatment if needed.

Abstract: 1,118,539. Transistor logic circuits. WESTINGHOUSE ELECTRIC CORP. 26 Oct., 1966 [13 Dee., 1965], No. 48044/66. Heading H3T. A logic circuit output transistor 10 is controlled by an input transistor 14 through the emitter-collector path of a coupling transistor 20 which is rendered non-conductive by a further transistor 22 to render the output transistor non-conductive but provides a temporary path for discharging the output transistor. As shown, the input transistor is of the multi-emitter type. When all its emitters are " up," transistor 22 conducts and provides base current for transistor 10 through the base collector path of 20. When one or more of the emitters are " down," transistor 14 conducts and cuts-off base current of transistor 20 and thus the current in transistor 10. The outflow of charge from transistor 20 produces by transistor action a transient current in the collector which removes the charge from transistor 10 so that it rapidly switches off. The circuit may be made in integrated form.
