Abstract: 1465568 Racemic or optically active derivatives of cyclopropane carboxylic acid ROUSSEL UCLAF 22 Oct 1974 [22 Oct 1973] 45653/74 Headings C2C and C2P The invention relates to racemic or optically active derivatives of cyclopropane carboxylic acid of cis or trans structure of Formula I in which R represents either a R 1  group which is either hydrogen, or an alkali metal atom, or an alkyl radical containing from 1 to 6 carbon atoms, substituted if necessary, or a R 2  group which is either a benzyl radical, substituted, if necessary, by one or more substituents selected from an alkyl, an alkenyl, an alkadienyl, a methylenedioxy, a benzyl radical and a halogen atom, or a cyclohexene dicarboximide methyl radical having a double bond at any position in the hexagonal nucleus and, if necessary, substituted on the said hexagonal nucleus by one or more halogen atoms, one or more methyl radicals or one or more acetoxy radicals, or a radical of formula in which Y 1  and Y 2 , the same or different, represent hydrogen, an alkyl, alkenyl or alkadienyl radical and Y 3  represents hydrogen, an alkyl, alkenyl, alkadienyl, alkynyl, or aryl radical or a heterocyclic radical, all these radicals being capable, if necessary, of being substituted, or a 1-oxo 2-Z 3-methyl 2-cyclopentene 4-yl residue of formula in which Z represents an alkyl, alkenyl, alkynyl, aryl, aralkyl, cycloalkyl, or cycloalkenyl radical or a heterocyclic radical. The compounds have insecticidal properties. Compounds of the general Formula I in which R is H are prepared by reacting 2,2-dimethyl 3- formyl cyclopropane 1-carboxylic acid, the configuration of which at the 1- and 3-positions is the same as that desired in the product, with a phosphonate or phosphorane containing a 1- ethyl propane-2-one 1-yl chain in the presence of a strong base. Suitable phosphonates include, for example, O,O-dialkyl alpha-ethyl acetonyl phosphonate and a suitable phosphorane is, for example, an alpha-ethyl acetonyl triaryl phosphorane, e.g. alpha-ethyl acetonyl triphenyl phosphorane. Compounds of the general Formula I in which R is other than H or an alkali metal atom are prepared by reacting a compound of Formula I wherein R represents hydrogen or an alkali metal (or a functional derivative thereof) with a compound of formula XOH (or a functional derivative thereof) wherein X represents a group R 2  or an optionally substituted alkyl group. When R represents hydrogen then this acid may, if desired, be used in the form of, for example, its acid chloride, anhydride, mixed anhydride or a salt. The alcohol of formula XOH may, for example, be used in the form of a halide derivative of formula X-Hal or an alkali metal derivative. Alpha-ethyl-acetonyltriphenylphosphorane is prepared by reacting propyltriphenyl phosphonium iodide with ethyl thioacetate. Dipropyl alphaethyl acetonylphosphonate is produced by reacting tripropyl phosphonate and ethyl acetate.

Abstract: 1401434 Photo-electric devices MULLARD Ltd 29 Sept 1972 [30 Sept 1971] 45667/71 Heading H1K In a device comprising inner and outer tubes both closed at one end and joined at their other ends to form an enclosure for one or more photoelectric elements supported on the closed end of the inner tube, the lead in conductors (as many as 120) consist of wires which are completely embedded in the glass wall of the inner tube from the closed end of the tube to points of emergence at the opposite end. In the embodiment, Fig. 2, the tubes are sealed by welding together flanges on associated iron nickelcobalt alloy sleeves 28, 31 to form an evacuated or inert gas filled enclosure. The wires 41 of NILOK (R.T.M.) are individually provided with insulating sleeves 45 where they emerge and potted in silicone rubber 44. Typically a linear array of six comb-shaped bodies of indium antimonide 60 each providing a number of photoelements with one electrode in common (Fig. 3, not shown) are stuck on alumina disc 23 and connected to the wires via flying leads thermocompression-bonded to the elements and wires and to intermediate gold strips 59 screen printed or sputtered on the alumina. In a modification a ring of glass is sealed around the closed end of tube 21 to prevent chipping around the wires when the end surface is ground flat prior to gold plating the wire ends, and to resist crushing by the thermocompression bonding tool. It also peripherally supports a radiation shield of anodized aluminium which has an aperture over the photo-elements. For operation at low temperatures a liquid coolant refrigerator or Joule-Kelvin or Leiden frost cooler may be located within the inner tube and the end of the outer tube closed by an infra-red window of silicon, germanium or sapphire. Suggested modifications are the use of a co-ordinate or annular array of elements, and of CdHgTe elements and provision of a pin mounting base.

Abstract: 1,247,887. Starch adhesives. CPC INTERNATIONAL Inc. 7 Oct., 1968, No. 47525/68. Heading C3U. A single starch adhesive, e.g. for making corrugated cardboard, is made by reacting an aqueous starch slurry with caustic alkali solution, e.g. NaOH, in a temperature-controlled vessel. The slurry and solution are both preheated to a predetermined temperature and mixed in the vessel. The vessel is provided with means monitoring the viscosity of the reaction mixture and which actuates means for discharging a chemical reaction stopper into the vessel upon detection of a predetermined viscosity, whereby the desired product is obtained. The reaction stopper may be boric acid or alum and borax, the latter two being added sequentially. The whole process may be fully automated using a solenoid-operated stepping switch which advances from one stage to the next in response to a feedback signal indicating completion of the stage. The levels, quantities and temperatures of reagents may be thus controlled using electrically operated valves. Steam may be used for heating. The whole process may be set in operation upon automatic detection of a low level in a vessel into which the finished adhesive is charged to be stored for use. A flow diagram and programme therefor are described and illustrated.
