Title: Process for the production of triaryl phosphites
IPC: C07F9/145
Filed: 1971-04-19
Abstract: 1348504 Preparing triaryl phosphites CIBAGEIGY AG 19 April 1971 [17 Feb 1970] 21973/71 Heading C2P A triaryl phosphite is obtained by reaction of a phenol with PCl 3 , the reaction being effected in three sequential stages corresponding substantially to the successive stages of formation of monoaryloxydichlorophosphine, diaryloxymonochlorophosphine and triaryl phosphite, by causing the reaction mixture to pass through three sequential reaction zones, each zone after the first being at a lower pressure but higher temperature than the immediately preceding zone. The phenol may be phenol itself or phenol having one or more alkyl or aryl substituents, e.g. nonyl phenol. Foam formation arising in the reaction may be diminished by the addition of an inert organic solvent and any excess phenol and any solvent present may be removed in a fourth zone at elevated temperature and under further reduced pressure. Each of the three reaction zones may comprise more than one reaction floor, and a suitable apparatus is described, the apparatus being in the form of a column provided with reaction floors at different levels, the internal configuration being such that a liquid will flow under gravity sequentially over the floors and preferably being such that the liquid will be constrained to flow through a sinuous path in its traverse of each floor, the path being defined by upstanding walls on the reaction floors each of which is provided with means constituting a weir defining a maximum level of liquid possible on each floor. Examples are given for the production of triphenyl- and tri-(nonylphenyl)phosphites.

Title: Photosensitive material processing apparatus
IPC: G03D3/06
Filed: 1970-05-07
Abstract: 1275867 Photographic processing apparatus LOGETRONICS Inc 7 May 1970 [17 Sept 1969] 11083/70 Heading G2A A film processor has a replenishment control system generally as described in Specification 1213941, the optical scanning of the developed sheets to produce an accumulated image density signal which is subsequently used to control the feeding of replenishment chemicals to the processor proceding at a fixed speed independent of the rate of feed of sheets through the processor. A sychronous motor 23, Fig.1, rotates a drum-like shutter member 16 having an aperture 19 so that light from lamp 17 illuminates in sequence twelve fiber optics bundles 20 which are equally spaced about lamp housing 15. The bundles are connected to transmitter sensors 25-28 which are disposed tranverse to the path of travel of a developed sheet 13, light passing therethrough on to receiver sensors 31-34 and via fiber optics bundles 30 to a photo-multiplier tube 36, Fig. 3 A zeroing bundle 21 is disposed directly between lamp housing 15 and tube 31, and when illuminated through aperture 19 the output of tube 31 is connected by magnetically operated reed switch 41 to a capacitor 60, the voltage of which adjusts the output of amplifier 61 and thus dynode regulating driver transistor 62. The photo-multiplier tube current is thus held constant irrespective of changes in line voltage and/or lamp brightness. When any of bundles 20 are illuminated, red switch 41 connects the tube output to the input of an integrator 50, 51 which accumulates information during the time taken for one scan of the film as controlled by pulses produced by transport pulse generator 45. The output of integrator 50, 51 is coupled to a further integrator 52, 53 which is itself coupled to a level  detector consisting of Zener diode 54a and transistor 54b. After a predetermined quantity of sheet image density has been detected, relay 56 is switched by transistor 55 to feed the information to a mechanical integrator 58 which in turn controls the operation of a time and valve control mechanism 59 which achieves replenishment in the film processor.
