Inventor: KURAMOTO SAICHIRO
IPC: C07F9/18
Filed: 1964-03-23
Abstract: The invention comprises compounds of the general formula <FORM:1029742/C2/1> wherein R is methyl, ethyl or isopropyl.  They may be obtained by condensing O,O-dimethyl phosphorochlorido-thioate with a compound of the general formula <FORM:1029742/C2/2> wherein M is hydrogen or an alkali metal atom and R is as defined above.  The reaction is preferably carried out in an inert organic solvent, e.g. a hydrocarbon, halogenated hydrocarbon, or an alcohol or ketone.  The reaction temperature is generally from room temperature to 120 DEG C., preferably 60 DEG  to 100 DEG  C.  A catalyst, e.g. copper powder or a cuprous salt, may be present. When the free phenol (i.e. M is H) is used the reaction is preferably carried out in the presence of a dehydrochlorination catalyst, e.g. an organic base such as pyridine or diethylamine, or an alkali metal carbonate or bicarbonate. The products have insecticidal properties (see Division A5).ALSO:An insecticidal composition comprises an inert carrier and as the essential active ingredient a thionophosphorus compound of the general formula: <FORM:1029742/A5-A6/1> wherein R is methyl, ethyl, or isopropyl (see Division C2).  The composition may be in the form of a dust, wettable powder, granule preparation, oil solution, emulsion or suspension.  A suitable emulsion is obtained by dissolving the compound in an organic solvent; e.g. benzene or xylene, adding an emulsifier and then diluting with water.  Other liquid diluents specified are kerosene and methylnaphthalene.  A granule preparation may be obtained by mixing the compound with a surface active agent and a powdered carrier, kneading the mixture with polyvinyl alcohol and water and moulding and drying the product. Other materials e.g. organophosphorus, organo-chlorine or carbamate insecticides, pyrethrum insecticides, acaricides, nematscides, fungicides, herbicides and fertilizers may also be present.

Patent GB-867462-A (GB)
Title: New octanoic esters and process for their preparation and utilization
IPC: C07C69/716
Filed: 1959-04-10
Abstract: The invention comprises octanoic esters of general formula: <FORM:0867462/IV (b)/1> wherein R1 represents the residue of a carboxylic acid e.g. from formic, acetic, phenylacetic or benzoic acids, and R2 an alkyl group preferably containing not more than 3 carbon atoms, and X and Y represent either respectively a hydrogen atom and a hydroxyl group, or collectively an oxygen atom.  The esters may be used in the preparation of a -lipoic acid.  The alkyl 8-acyloxy-6-ketooctanoates are prepared by reacting alkyl 6-keto-7-octenoates with carboxylic acid, e.g. acetic acid, preferably anhydrous, in excess at elevated temperatures and atmospheric pressure under an inert gas preferably in the absence of light or oxygen in the presence of an antioxidant.  The keto-octanoates may be reduced by known methods e.g. by hydrogenation with Raney nickel, or with aluminium isopropoxide in isopropanol, r alkali metal borohydride in anhydrous methanol to the alkyl 8-acyloxy-6-hydroxy octanoates.  The preparations of methyl-, ethyl-, isopropyl-8-formyloxy and -8-acetoxy-6-keto-octenoates, methyl- and ethyl-8-benzoyloxy-6-ketooctanoates, methyl-, ethyl-, and isopropyl-8-acetoxy-6-hydroxyoctenoates and ethyl-8-formyloxy-6-hydroxy octenoate are exemplified together with the preparation of 6,8-dithio-octanoic ester from methyl-8-acetoxy-6-hydroxy octanoate.  The hydroxy-octanoates may be used to form dithio-octanoic acid by reacting with thio-urea in a hydrohalic medium and treating the product with alkali, or alternatively by hydrolysing to 6,8-dihydroxy-octanoic acid and treating with thio-urea, or halogenating and treating with alkali hydrosulphide to yield dithiooctanoic acid which reacted with alkali disulphide is converted to a -lipoic (5-(11,21-dithiolane-3-yl) pentanoic acid.

In a mass spectrometer solid sample ion source arrangement an insertion probe structure, demountably carrying at one end at least one solid sample, is introduced into the ionization chamber through a vacuum lock without breaking the vacuum, the ionization means is separate from the probe structure and a preliminary ion-etching cleansing action on the sample may be effected by a discharge in argon between the sample and an annular anode 9. The ionization means may comprise an external laser beam generator the laser beam entering the ionization chamber through a window, or, as in the arrangement shown, arc- or spark-electrode structures 11, 12. The probe structure 3 insertable through a rotary vacuum lock 5 of the type described in Specification 1,092,803 comprises an inner rod (shown in dotted outline) movable to an extent determined by a key K to effect a transfer of the sample holders 25, 26 to slotted electrode clips 15, 16. The sample holders 25, 26 are pivotally mounted on an end member 27 of the probe structure 3 and a withdrawal motion of the inner rod followed by a rotation causes eccentrically positioned projections 28b to displace the sample holders from upright positions into the positions shown. A subsequent movement of the probe structure lifts the pivots for the sample holders clear of the slots therein; the electrode structures 11, 12 can then be swung aside and the probe structure withdrawn.

Cigars are passed through an enclosure 2 having apertures 3 communicating with the atmosphere and supplied with compressed air from a compressor 5 via a cooler 7, a reservoir chamber 10, and a unit 12 provided with a liquid column and measuring scale for indicating the pressure within the enclosure 2 and thereby the diameter of the cigar passing therethrough. The cooling of the compressed air is so controlled that its humidity is unchanged and is the same as that in which the cigars have been kept. Alternatively newly manufactured cigars are passed by a conveyer 14 Fig. 2, (not shown) through a chamber in which they are subjected for a period to an airflow from a compressing, cooling, and condensing unit, before passage through the measurement tube which is supplied with air by the same unit.

Filed: 1949-05-10
Abstract: 662,885. Furnaces. STEVENS, A. H. (Anthracite Equipment Corporation). May 10, 1949, No. 12432/49. Class 51 (i). [Also in Groups XI and XIII] Heating apparatus comprises a fuel chamber with an opening for discharging ash, an opening through which fuel is supplied continuously so that an ejecting force is exerted on the ash, compartment means for heating a fluid medium surrounding passage means for the escape of combustion gases and means for continuously causing a draught through the fuel and causing combustion gases to pass through the passage means at high velocity to accelerate heat transfer. In one embodiment of the invention (Fig. 1) a chamber 11 is fed with fuel through an opening 13 and ash is discharged through openings 15<SP>1</SP>, 15 in the casing of the apparatus through which the ends of a grate 14 project. The combustion chamber 11, the fan compartment 23 and the passages through which combustion gases are led to the chimney are surrounded by a fluid-containing compartment, a part of which forms a channel 37 passing through the combustion chamber in contact with the fuel to prevent active burning at the top of the pile. Combustion gases are drawn upwardly by a fan 45 through the space between the channel 37 and the main part of the fluidcontaining compartment into which heat conducting bars 50 may extend from the fluidcontaining compartment. They then flow horizontally through an opening 36 into the fan compartment 23 from which they are dispelled through a chimney 32. Fly ash entering the fan compartment 23 is prevented from reaching the chimney 32 by a baffle 47 which deflects it through a passage formed between the fan chamber 23 and a plate 28 to the combustion chamber 11. In a modification of the invention (Fig. 5) gases are drawn from the combustion chamber 61 by a fan 69 through a horizontal passage 68. The fan drives the gases through an annular passage 71 surrounding the horizontal passage 68 and thence through a duct 77 to a vertical flue 79 which they enter tangentially. Fly ash separates out and falls through the vertical flue 79 to the grate 64 at the base of the combustion chamber 61. Fuel is supplied continuously to a hopper 63.
