Abstract: 1,229,425. Germicidal sutures. L. D. KURTZ. 15 March, 1968 [23 June, 1967], No. 12686/68. Heading A5E. A method of imparting germicidal properties to a suture comprises swelling the suture with a first solution containing first high molecular weight ions and then with a second solution containing second high molecular weight ions of opposite charge, at least one of the ions being germicidal, whereby an insoluble precipitate is formed in the body of the suture. In a modification the suture may be pre-swelled before contacting with the solution of ions. Optionally when a non-germicidal ion is used, it may have pharmacological activity. Specified active ions are those deriving from benzethonium chloride, benzalkonium chloride, lauryl dimethylbenzylammonium chloride, cetyl dimethylbenzylammonium chloride, lauryl pyridinium halide, bacitracin, polymyxins, tyrothricin, viomycin, vancomycin, neomycin, erythromycin, streptomycin, carbomycin, nystatin, kanamycin, puromycin cycloserine, tetracycline, aureomycin, oxytetracyclin, subtilin, anisomycin, penicillin, fumagillin and heparin. The suture may be made of materials selected from silk, cellulose, cellulose esters, polyamides, polyacrylics, polyesters, polyolefins, polyvinyls and cotton.

Abstract: 1,239,009. Photographic processing apparatus. EASTMAN KODAK CO. Oct. 3, 1969, No. 48618/69. Heading G2A. As a sheet of material passes between processing rollers, the rollers rotate so that the peripheral portions engaging the sheet rotate in the same direction as the sheet movement as the leading end of the sheet enters between the rollers, and then reverse so that they are rotating opposite to the sheet movement as the trailing edge leaves them. Fig. 1 shows a photographic film processing apparatus, the film sheet 15 being introduced into the apparatus between rollers 16<SP>1</SP>, and sprayed by heads 18 with developer solution which is then spread by a flap 20. As the leading edge of the sheet reaches a switch arm 46<SP>1</SP>, this is tripped to start a timer motor. The film sheet is then carried through a further developing station 10 by transport rollers 16, the lower of each pair dipping into a bath 17 of developer solution and applying it to the film sheet. Further rollers 36, initially rotating in the same direction as rollers 16, but faster, have a roughened surface, which exercises a scrubbing effect on the film, to improve the processing action. After sufficient time has elapsed for the sheet to be engaged by the first roller pair 16 of station 10, the drive to the entrance rollers 16<SP>1</SP> is disabled, so that no further sheets 15 can be fed into the apparatus for the time being. At the same time, the direction of rotation of the scrubbing rollers is reversed, so that they are acting against the movement of the film as the trailing edge leaves them, and so do not damage this edge. Similarly, as the sheet then passes to a de-sensitizing station 12, the scrubbing rollers 36, now reversed from the movement shown in Fig. 1, are rotating with the movement of the sheet, and so do not damage the leading edge. When the trailing edge of the sheet has passed switch arm 46<SP>1</SP>, the timer mechanism is re-activated. After sufficient time has elapsed for the trailing edge to clear the scrubbing rollers at station 10, all these rollers are reversed again, so that the scrubbing rollers at station 12 will not damage the trailing edge. The sheet now passes through a drying station 14, and is guided upwards and out of the apparatus through an exit opening 32.

Abstract: 1,258,892. Selective signalling. IMPERIAL CHEMICAL INDUSTRIES Ltd. 8 Jan., 1969 [10 Jan., 1968], No. 1439/68. Headings G4A and G4H. The Gray code output of a counter comprising JK flip-flops F a -F c  is converted to binary by exclusive OR gates connected as shown, the least significant bit a, of which (representing the Gray code parity) determines the direction of counting in conjunction with a control input applied to a further exclusive OR gate. The counter is constrained to assume Gray code states in response to successive input pulses by the intermediate gates (NAND or NOR) which enable a stage to change state only when the next lower stage holds a 1 and all the other preceding stages hold a 0. The direction control is based on the fact that for each input pulse, a change in state in stage F a  effects a count up or down depending on whether the existing parity is even or odd, the reverse being the case for all other stages, and an additional inverting gate is therefore included in the control input to F a . By imposing a 1 on the control input, the effective parity is reversed and the direction of counting is also reversed. An additional stage F, Fig. 5 (not shown) can automatically reverse the counting direction on overflow, and a counter of this type may provide the control input to a number of slave counters forming part of a telemetering scanner.
