Abstract: 1505617 Partial carbodiimidization of organic isocyanates BAYER AG 20 Aug 1976 [23 Aug 1975] 34780/76 Heading C2C [Also in Division C3] Partial carbodiimidization of the isocyanate groups of a mono- and/or poly-isocyanate is effected by mixing, at 0-200‹ C., the isocyanate with from 0À1 to 100 p.p.m. of a phosphorus compound of general formula where R is H, alkyl, halo-alkyl, alkenyl, alkoxy, phenyl or alkyl- or halo-phenyl; a, b, c and d are each H, halogen, alkyl, alkenyl, cyclohexyl or phenyl or a and b, b and c or c and d, together with the C atoms to which they are attached, may form a cycloaliphatic ring; and X is O or S, and terminating the carbodiimidization reaction, after the evolution of 1-90% of the theoretical quantity of CO 2  which would be evolved by carbodiimidization of all the -NCO groups, by adding to the phosphorus compound at least an equivalent quantity of a compound which deactivates it by formation of a salt or adduct therewith. The deactivating compound may be HCl, HBr or an inorganic or organic acid chloride or bromide. The invention also includes an isocyanate mixture comprising a partially carbodiimidized isocyanate and 0À1-100 p.p.m. of a phosphorus compound of the above general formulµ but wherein R is C 1-4  alkyl, C 1-4  alkoxy or phenyl, a, b, c and d are each H or C 1-4  alkyl, and X is oxygen, the phosphorus compound being in a form deactivated by a deactivating compound as specified above. In examples, 4,4<SP>1 </SP>- diisocyanatodiphenylmethane and/or tolylene-2,4- or 2,6-diisocyanate, hexamethylene diisocyanate, isophorone diisocyanate and a mixture of biuretized hexamethylenediisocyanate and tolylene-2,4-diisocyanate are partially carbodiimidized; phenylisocyanate is partially carbodiimidized, the carbodiimide formed then reacting with further isocyanate to give triphenyluretonimine; and o,o<SP>1</SP>-ditolylcarbodiimide is prepared by partial carbodiimidization of o-tolylisocyanate followed by fractionation and separation of non-carbodiimidized isocyanate.

[Also in Group XX] A photo-electric exposure meter has a plurality of easily removable and interchangeable dials, each dial corresponding to a different emulsion speed and carrying graduations associating diaphragm openings and shutter speeds for the given emulsion speed, whereby the correct diaphragm opening and shutter speed can be read off directly, immediately the light intensity reflected by the subject is measured by the photo-electric cell. As shown, the dial is printed on a sheet 5 inserted into the body 1 of a photo-electric exposure meter along guideways 6 and located by stops 11. The pointer is observed through a window 3. A part 7 of the body 1 is cut away so that a projection 8 of the sheet 5 may be gripped for removal. A set of dials may be prepared bearing (preferably on both sides) scales for one or more emulsion speeds, which may take the form of concentric arcs corresponding to shutter speeds and' graduated in diaphragm apertures, or vice versa, or two sets of intersecting curves indicating shutter speeds and diaphragm apertures respectively. Separate dials may also be prepared for instantaneous and time exposures, or a dial for short exposures may have a supplementary arbitrary scale of light values, from which longer exposures may be calculated. Each dial may be rotatable through a small angle to bring into use one of two scales inscribed side-by-side. The Specification as open to inspection under Sect. 91 states that the dials may be opaque or transparent, and also describes a meter with two dials inscribed on a strip pivoted to the case, and a meter with dials carried by a long strip wound and unwound between drums, with registration marks on the strip and on the meter case.

Abstract: 1,267,547. Measuring temperature electrically. SIPPICAN CORP. July 16, 1969 [July 24, 1968], No.35796/69. Heading G1N. Apparatus for measuring sea temperatures comprises a probe assembly 14 including a thermistor 16 and two electrodes B, C, forming contacts of a fluid-actuated switch which closes the earthreturn path for the energizing current of a bridge circuit so as to initiate recordings as soon as the probe reaches the ocean surface, having been released from an aircraft 10 on a three-core conductor cable, 18. The energizing current for the bridge is supplied by a differential feedback amplifier A1 to which the input voltage is the bridge unbalance voltage, the arrangement being such that the energizing current is inversely proportional to the resistance RTH of the thermistor. The bridge operation is as described in Specification 1,190, 996 (see Division G1) wherein a separate servosystem positions the slider of a potentiometer R6 so as to yield the ratio of energizing current to a reference voltage f, whereby the slider travel provides a measure of sea temperature. The chart drive speed of a recorder to which the slider is mechanically linked is proportional to the rate of descent of the probe through the water, thus plotting temperature as a function of depth. A signal to release a braking parachute 20 is derived from the bridge or from strain gauge on the probe housing at splash-down of the probe. It is stated that alternative resistive sensing elements are used in place of the thermistor to measure salinity or conductivity.
