Title: Method for adjusting the bromide ion concentration in a photo- graphic processing solution
IPC: B01J20/06
Filed: 1973-09-18
Abstract: 1394540 Regenerating photographic processing solutions KONISHIROKU PHOTO INDUSTRY CO Ltd 18 Sept 1973 [22 Sept 1972] 43706/73 Heading G2C  In the regeneration and replenishment of photographic processing solutions, such as developers, bleach-fix and fixer solutions, the bromide ion concentration of the solution is reduced by contacting the solution with an insoluble bismuth compound such as bismuth trioxide, tetroxide, pentoxide or hydroxide which absorbs the bromine ions from the solution. The compound in particulate form may be added to the solution and then filtered off, or a bag containing the compound may be suspended in the solution or the solution may be pumped through a column packed with the compound. The bromide ions may be desorbed by treating the compound with strong alkali and the compound may be washed and used again. The treatment of lithographic, black-and-white and colour developers, bleach-fix and fix baths is described.

Abstract: 1,022,819. Jointing by stamping. AMP Inc. Nov. 4, 1964 [Nov. 21, 1963], No. 44916/64. Heading B3Q. [Also in Division F2] A press for crimping connectors 4, Fig. 1 (not shown), to a wire C comprises a sensing device 5 engaged by the wire when this is located in the press, contact between the wire and sensing device altering the current-flow through an electronic control 13 to operate the press. The control 13 operates a relay circuit 12 controlling a clutch 11 which engages the drive between an electromotor and the press. Descent of the crimping die 7 carries the wire into the leading connector 4, which is crimped to the wire and is severed from the strip of connectors by a blade 8 on the press-ram 2. The adjustable, triangular sensing head is connected to the control circuit by a coaxial cable 14. The control circuit includes two resonant transistor-circuits 24, 25, Fig. 4 (not shown), to which power is supplied through a rectifier 32. During oscillation the voltage developed across a resistor 39 is greater than the switching voltage of a diode 48 so that a transistor 49 conducts and energizes a coil 52 in the relay-circuit 12. This operates relay contacts 52<SP>1</SP> to maintain the clutch 11 open. When the sensing device 5 is touched by the wire C, the capacity this adds to the oscillatory circuit causes a reduction in voltage across the diode 48, which becomes non-conductive so that current is no longer supplied to the base of transistor 44. The coil 52 is thus de-energized, switching the relay contacts and closing the clutch. In a modification, Figs. 5 and 6 (not shown), the sensing device 5<SP>1</SP> comprises a thermistor enclosed in body of aluminium, copper or brass. The circuits comprise a detector circuit 54, an amplifier circuit 55, a relay control circuit 56, and a battery circuit 57 to a rectifier circuit. The current flowing through the thermistor keeps the temperature of the thermistor in excess of its normal ambient temperature. When the wire C<SP>1</SP> touches the device 5<SP>1</SP> is conducts thermal energy away from the device, altering the ratio of currents developed by resistors 59, 60 and the thermistor and changing the base current of a transistors 58, 63. Further transistors 66, 67 forming a trigger circuit, actuate the delay coil 72, the press being operated when the coil is energized.
