Title: New colouration process
Inventor: KRAUS FRANZ
IPC: D06P3/66
Filed: 1961-07-13
Abstract: Knitted cellulose textile fabrics are coloured by applying to a portion of one surface of the fabric a thickened printing paste which contains a nitrogenous resin precondensate and a curing agent, thereafter heating the fabric to cure the resin and thereafter immersing the fabric in an aqueous solution of a water-soluble reactive dyestuff and an acid-binding agent.  The nitrogenous resin precondensate may be the methylol derivatives, or lower alkyl ethers thereof, of monomeric or polymeric compounds containing a plurality of amino or mono-substituted amino groups, the preferred precondensates being 4, 5-dihydroxy-1, 3-dimethylol-2-unidazolidone and tetramethylol acetylene bisurea. The specified curing agents are zinc chloride, ammonium sulphate, ammonium chloride, oxalic acid, magnesium chloride and ammonium thiocyanate but preferably at least a part of the curing agent is a compound containing a halogeno-s-triazine radical, e.g. 2-(61-sulpho-21-naphthy-lamino)-4 : 6-dichloro-s-triazine, 2-(51-sulpho-11-naphthylamino)-4: 6-dichloro-s-triazine and 2-(21 chloroamilino)-4 : 6-dichloro-s-triazine.  Suitable thickening agents are tragacanth, gum arabic, alginates, oil-in-water and water-in-oil emulsions and especially caragheen moss extract and etherified locust bean gums. Lubricants or softening agents, e.g. methylol stearamide, may also be added.  The printing paste may further contain a water-soluble reactive dyestuff whereby coloured resists are obtained.  The fabric is preferably dried at 75-125 DEG C. and cured at 150-160 DEG C.  The immersion of the fabric in the aqueous reactive dye solution may be effected by slop-padding, on the jig or especially, on the winch at a goods : liquor ratio of about 20 : 1.  Specified acid binding agents are sodium carbonate and bicarbonate, sodium silicate, sodium triphosphate and caustic soda.  The solution advantageously also contains a neutral salt such as sodium chloride or sulphate. Examples are given of colouring cotton locknit fabrics.

Title: Steady state phase error correction circuit

Filed: 1971-04-19
Abstract: 1294265 Automatic speed control AMPEX CORP 19 April 1971 [2 April 1970] 25785/71 Heading G3R In a phase controlled servosystem, such as that for synchronizing the rotary heads of a video tape recorder disclosed in Specification 1294264, means 10 is provided for developing a variable D.C. error signal for eliminating static phase errors and comprising a phase sensitive device 136 for sensing the direction of the error; a counter 137 arranged to count clockpulses, up or down according to the sensed direction, whenever there is a phase error; and a digital to analogue converter 142 to convert the count to a D.C. error signal. When the tape synchronizing system reaches the final stage of synchronization as described in the above Specification small static phases errors exist between the studio reference pulses and those derived from the reproduced video signal. These two signals are applied to the terminals 48, 49 respectively of the circuit. A bi-stable device 136 detects which pulse appears first and conditions the counter 137 to count up or down accordingly. A divider (by eight) derives low speed clockpulses from the studio reference 48. The clockpulses are fed to the counter 137 by a gate 159 which blocks the pulses whenever there is coincidence between the studio and reproduced pulses as detected by 149, when the counter reaches the limit of its count in either direction and during earlier stages of synchronization (input 156). The counter has a maximum count of 64 and the converter 142 gives zero output when the count is 32; it provides an incremental increase in the D.C. signal for each change of count.

Title: Method for determination of the presence of antibiotics
IPC: G01N33/12
Filed: 1973-05-31
Abstract: 1467439 Testing for antibiotics GISTBROCADES NV 29 May 1974 [31 May 1973] 25947/73 Heading G1B [Also in Division C6] A method for the rapid determination of the presence or absence of residues of antibiotic in a liquid e.g. milk, liquids derived from meat, blood serum and urine, involves introducing spores of a micro-organism sensitive to the antibiotic to be determined into a liquid agar medium containing insufficient nutrients to permit germination of the live spores, the spore culture thus obtained being allowed to solidify in upright transparent or translucent test vessels having an internal cross-sectional dimension of 3 to 20 mm., placing on the agar surface nutrients required for growth of the spores of the micro-organism, followed, if desired after a preincubation period, by adding a predetermined amount of sample liquid to be tested to the test vessel, and incubating at or near optimal temperature the contents of the test vessel for a predetermined time so that the extent of growth or inhibition of growth of the micro-organism into the agar medium, observed visually, indicates absence or presence of antibiotic. The height of the sample to be tested and the agar medium together is typically 3 to 30 mm. The spore culture contains 10<SP>5</SP> to 108 spores of micro-organism per ml. of agar medium spores of Bacillus calidolactis, Bacillus subtilis, Bacillus stearothermophilus or Bacillus stearothermophilus var calidolactis being preferred. The requisite nutrients may be applied on to the surface of the agar in the test vessel in the form of wax-coated filter paper discs or tablets allowing transport of the nutrients into the agar under the temperature of incubation viz. in the range 55C to 70C. The resulting composite article may be packaged in foamed polystyrene. A chemical indicated, specified, is included either in the agar medium or with the nutrients. A number of test vessels may be formed in a block of translucent material. The term "antibiotic" is taken to include certain specified chemotherapeutics. An Example relates to the testing of penicillin residues in milk. The use in a second test of a medium containing penicillinase, or cysteine, confirmed that the antibacterial activity was attributable to penicillin.
