Title: Manufacture of azo-dyestuffs
IPC: C09B43/10
Filed: 1930-10-15
Abstract: Azo dyes are made by subjecting a nitrobenzoylated azo-dyestuff, obtainable by coupling a mononitrobenzoylated diaminoarylsulphonic or carboxylic acid with any final component or by condensing an aminoazo dyestuff containing a sulphonic or carboxylic group with a nitrobenzoyl chloride, to an alkaline reduction under mild conditions so that two molecules are linked with formation of an azo-group or azoxy group.  They have a good affinity for cotton fibre and are fast to mineral acids.  In examples, (1) the azo dyestuff 1-amino-4-(4<1>-nitrobenzoylamino) - benzene - 2 - sulphonic acid --> 1-p-sulphophenyl-3-methyl-5-pyrazolone is reduced with alkaline glucose; the product is identical with that obtained in example 1 of Specification 338,672, [Class 2 (iii), Dyes &c.]; the mono-nitrobenzoyl derivatives of benzidine-2 : 2<1>-disulpho acid, 4 : 4<1>-diaminostilbene-2 : 2<1>-disulpho acid, 4 : 4<1>-diaminodiphenylurea-3 : 3<1>-disulpho acid and 1 : 4-diaminobenzene-2-sulpho acid may be used as diazo components; (2) the dyestuff 4-(4<1>-nitrobenzoylamino)-1-amino-benzene-2 : 6-disulphonic acid --> 2 : 8 : 6-acid (acetic acid coupling) is reduced as above; (3) the dyestuff 2-naphthylamine-4 : 8-disulphonic acid --> m-toluidine is p-nitrobenzoyllated and reduced to the azo compound as above; (4) the disazo dyestuff 4-diazoazobenzene-4<1> : 3-disulphonic acid --> m-toluidine is treated as in (3).

Title: A method for manufacturing articles having fibrous surfaces and a spongy padding
IPC: B29C65/00
Filed: 1965-07-21
Abstract: 1,120,103. Laminating. G. GABELLA. 21 July, 1965, No. 31114/65. Heading B5N. A method of manufacturing articles comprising two outer layers 2<SP>1</SP>, 2<SP>11</SP> of fibrous material, e.g. woven fabric or felt, and a padding 1 made of thermomeltable spongy material, e.g. a polyvinyl chloride sponge, comprises the steps of placing the padding between the outer layers to form an assembly, disposing the assembly between two electrodes 3<SP>1</SP>, 3<SP>11</SP> having a prominent contour corresponding to the contour of the article to be manufactured, bringing the electrodes into contact with the assembly by means of pressure applied to the electrodes, and connecting the electrodes to a high frequency electric source, so that the thermomeltable spongy material is melted along the prominent contour of the electrodes, and the melted material sticks together the two outer layers and finally pressing together the electrodes so that the layers of fibrous material are destroyed along the contour of the electrodes to separate the manufactured article from the surrounding material. In the embodiment shown the electrodes 3<SP>1</SP>, 3<SP>11</SP> are supported on insulating plates 4<SP>1</SP>, 4<SP>11</SP> and after the assembly has been placed between them the electrode 3<SP>11</SP> is lowered under the action of pressure fluid via a piston 5<SP>1</SP>. The melting of the spongy material then takes place and subsequently the electrode 3<SP>11</SP> is lowered further under the action of pressure fluid on an annular piston 5<SP>11</SP>, having a larger crosssectional area than the piston 5<SP>1</SP>, so that the electrodes cut the article from the surrounding material. In other embodiments the piston 5<SP>11</SP> is replaced by a number of pistons or there is a single piston 5<SP>1</SP> advanced first under low and then under high pressure. In a second embodiment (Fig. 5, not shown) the electrodes 3<SP>1</SP>, 3<SP>11</SP> are formed on the surfaces of insulating cylindrical rollers which are mounted in an articulate linkage incorporating a piston and cylinder unit, so that the distance between the rollers can be adjusted. The piston and cylinder unit may be replaced by a hand wheel operated screw.

Title: Method and apparatus for identifying bacteria
IPC: G01N21/27
Filed: 1971-07-02
Abstract: 1327339 Identifying bacteria photo-metrically COMPAGNE GENERALE D'AUTOMATISME 2 July 1971 [2 July 1970 22 Feb 1971] 31207/71 Heading G1A In an apparatus for identifying bacteria by photo-metrically monitoring the reaction in a cell 7 between a suspension of the bacterium of interest and a chemical reagent, in the presence of a coloured indicator, two different wavelength bands are passed alternately and repeatedly through the test solution so as to monitor the changing transmissivity with time of the test solution at these two wavelengths. The wavebands are selected so that the transmissivity of the solution in one waveband increases with time, while the transmissivity in the other waveband decreases with time. The different wavebands are provided by switching two filters 5 alternately into the light path. The output from a photo-multiplier 10 hence comprises a sequence of pairs of first and second measuring signals, corresponding to the two wavebands, and these signals are amplified at 11, converted to logarithmic form at 15 and inverted at 17. First and second reference signals are generated at S 0  corresponding to the photo-multiplier output for the two wavebands with only the bacterial suspension in the cell 7. After conversion to logarithmic form at 16, each reference signal is combined with the corresponding measuring signal in an adder 18 and a switch 20, 21 routes the first and second combined signals to memories 23, 24 respectively. At the start of a reaction, resistor 12 is adjusted to give a zero output from adder 18, for both sets of signals. As the reaction progresses, the outputs d and d 2  from 23, 24 become non-zero and are combined in an adder 25 and a comparator 26. The comparator 26 forms a digital signal dependent on the relative value of d 2  and d 1  + d 2 , which signal takes any one of n predetermined values according to the state of the reaction. From these values curves representing the course of the reaction can be plotted to be compared with those for known bacteria to provide the identification. The adder 18 may take the form of an operational amplifier circuit (28), Fig. 3 (not shown) with means (27, 29) for providing different gains for the two sets of signals. The choice of the two wavebands to be utilized may be widened by providing a plurality of filters on a filter wheel 5, two of these filters being of grey glass and obscured glass respectively. A number of samples contained in different cells 7 may be examined automatically in sequence, a controlling circuit being provided to bring each cell into the measuring position in its turn.

[Class 135.] Rotary cylindrical valves; outlets; locking.-A telescopic discharge tap and spout for liquid receptacles comprises a tube 1, as shown in the Figure, which is held secure in its mounting block 3, in the drawn-out position shown, by conical surfaces at 7 when in its withdrawn position and is secured when nested or pushed in, in readiness for transport, by screw engagement at 5, 21. The closure member consists of a ported rotary tubular member 2, and its rotation is limited by a tenon 11 sliding in an arcuate slot in the tube. The closure member is locked against rotation, in the nested position, by the inclined head 16 of the tenon 11 which is automatically pressed down into a wider portion of the slot in the tube as the tube is nested. When the tube is withdrawn the closure member is normally locked by a shoulder 18 on the tenon 11 which is pushed by the spring 13 into engagement with the wider portion of the slot. The head 16 is depressed to bring the reduced neck 17 opposite the groove before the plug can be turned to open the tap. A tubular strainer is secured in the conical inner end 8, 9 by a bayonet slot 23. Rotation of the tube 1 with the plug 2 is prevented by a projection on the tube engaging one of a series of notches 10 in the mounting block 3.

[Also in Division D1] The materials distributing system of the parent Specification is modified in that the selector switch(es) now have a number of operating positions equal to the number of sources. As shown, stations 1000 and 1042 are always supplied from sources B and A respectively, while station 1040 may be supplied from B or A (but not both) according to the position of gauged selector switches 1063 and baffles 1064, 1066, but in Fig. 1 (not shown), either of two sources may be selected independently for each of three stations, and in Fig. 3 (not shown) any of three sources may be selected for each of six stations, the selector switches in this case being of rotary type (or multi-pin plugs may be used). When more than one station is supplied from one source they are supplied sequentially, and at the end of the sequence the system is "purged" repeatedly by cyclic operation of relays such as 1106 at a rate determined by unspecified delay in the relays. "Purging" means that the source is shut off but the "transition valves" at each station remain open for a time; these valves are repeatedly open and closed for repeated purging. The overall operation is controlled by level limit switches at each station as in the parent Specification. A "transition valve" is shown at 1000; when a pneumatically actuated valve 1008 is opened by the control system air and fibres enter at 1006 and blow open a flap 1024. Rotating doffers 1028, 1030 remove the fibres, which exit at 1002, while the air flows through perforated screens 1032 to the exhaust duct 1034 and fan 1036.
