Title: Treatment of cellulosic fabrics
IPC: D06M15/423
Filed: 1961-12-27
Abstract: Cellulosic fabrics are creaseproofed by treating them with an aqueous solution of an aminoplast resin precondensate and/or formaldehyde and heating them to a temperature higher than 100 DEG C. in the presence of (1) a polyhydric alcohol and/or (2) an alkali metal thiocyanate or an alkaline earth metal thiocyanate. Suitable polyhydric alcohols are diethylene glycol, 1-arabitol, isobutylene glycol, ethylene glycol, glycerine and butane diol. The aminoplast resin precondensate may be dimethylolurea, a methylolmelamine, a methylolalkyleneurea, a methyloluron or a methyloltriazone.  The aminoplast resin precondensate and/or formaldehyde may be applied with an acidic catalyst, e.g. sulphuric, hydrochloric, phosphoric, formic, acetic, monochloracetic, trichloracetic, dibromoacetic, oxalic or tartaric acid, aluminium chloride or nitrate, ammonium chloride, magnesium chloride or nitrate, zinc nitrate, pyridinium chloride or an alkanolamine hydrochloride.  When formaldehyde is used the treating composition preferably contains an aldehyde carrier, e.g. a polyacrylate or cellulose ether.  The treating composition may also contain a blueing agent, whitening agent and/or softener, e.g. a polyethylene emulsion.  The treating solutions preferably contain 5-40% by weight of thiocyanate, 3-15% by weight of the polyhydric alcohol and more than 3% by weight of the aminoplast resin precondensate or formaldehyde.  The amino plast resin precondensate and/or formaldehyde and the polyhydric alcohol and/or thiocyanate may be applied to the fabrics from the same aqueous solutions or separately.  After impregnation the fabric may be dried at 50 DEG -100 DEG C. and then heated at a temperature higher than 100 DEG C. if desired in an atmosphere of steam or in hot air containing more than 40% of moisture.  Alternatively the fabric may be heat treated by passing it through a mass of molten metal or molten salt.  Woven or knitted fabrics containing cotton, hemp, linen, viscose rayon or cuprammonium rayon fibres alone or in admixture with cellulose acetate, polyamide, polyester, polyacrylonitrile, polyolefine, polyvinyl chloride, polyvinylidene chloride or polyvinyl alcohol fibres, may be treated.

Patent GB-1084984-A (GB)
Title: Production of pure chlorosulfonic acid
IPC: C01B17/46
Filed: 1965-11-05
Abstract: Pure chlorosulphonic acid is produced by reacting together sulphur trioxide and hydrogen chloride in liquid chlorosulphonic acid at its boiling point.  The liquid chlorosulphonic acid at its boiling point is supported in a column 1 by packing 5 above a perforated plate 6. The <PICT:1084984/C1/1> hydrogen chloride is introduced through an inlet 4 and the sulphur trioxide through an inlet 3.  The gases react together in the packing 5 and the chlorosulphonic acid is removed immediately it is formed and cooled in a cooler 10 to a temperature below 50 DEG  C. As the chlorosulphonic acid from the packing passes to the bottom 8 of the column any unreacted sulphur trioxide remaining is treated with further gaseous hydrogen chloride.  Any evaporated chlorosulphonic acid is condensed by the reflux condenser 2 and returned to the packing whilst excess hydrogen chloride is led off at 7.

Title: Dynamic filter
IPC: H03H11/04
Filed: 1972-10-11
Abstract: 1404988 Voltage measuring PERKINELMER CORP 11 Oct 1972 [29 Dec 1971] 46984/72 Heading G1U [Also in Divisions G3 and H3] A filter suitable for an analogue or digital measuring device comprises means producing a control signal when the rate of charge of amplitude of the input signal exceeds a given value and impedance means controlled by the control engine to vary the time content of the filter. Fig. 2 shows a filter 10 having its series resistance arm shunted by a field effect transistor acting as a variable resistor. The filter input signal, e i  is also passed via a gate 80 or switch 35 and an amplifier 37 to a differentiator 54, 55. If the rate of charge exceeds the threshold value of a circuit 44 in either polarity or full-wave rectifier 73, 64, 74 causes the field effect transistor to conduct and lower the time constant of the filter so that filtering is effective for slowly varying signals but follows rapid variations quickly. It is suggested that the control signal could alternatively narrow the band of the filter. Where the input signal is derived from an arrangement producing an unwanted cyclic component, e.g. from a chopper circuit, the component may be removed by using a gate and store circuit 80 synchronized with the component. The invention may also be used to prevent jitter in analogue or digital measuring instrument readings.

Abstract: 1322926 Coating labels H KROWSEDER 2 Oct 1970 [4 Oct 1969] 47021/70 Heading B2L [Also in Division B8] A labelling device comprises a label feeder, a rotary transfer device to convey labels from the feeder to articles to be labelled, and a glueing drum arranged adjacent the transfer device, one or more gripper elements on the transfer device gripping the labels only by their foremost ends in such a manner that said foremost ends are held thereby so that said foremost ends become tangential to the glueing drum as they pass said drum, the transfer device having at least part of its periphery radially spaced from the glueing drum such that during application of the glue to the labels as they pass the glueing drum portions of the labels remote from the gripped ends are unsupported radially by the transfer device. As shown (Fig. 2) two transfer devices 7, 7a are supported on a common shaft 22, body labels 13 being fed from magazine 12 via a rotary suction feeder 10 to device 7, and neck labels 13a being similarly fed to device 7a. Apertures 14 in the feeders 10 register with the grippers 16 to prevent fouling. The grippers 16 are mounted on a shaft 17 and are opened and closed in accordance with a fixed cam 21. The gripped labels are transported past the glue drum 8 (Fig. 6) in such manner that the trailing portion is engaged against the drum partly by centrifugal force and partly by the glue on the drum. A blast of air from nozzles 28, 28a may also be supplied to assist said engagement. As shown in Fig. 6 the glue drum 8 is synchronised with the transfer device 7 and has sliding members 9 controlled by a fixed cam 30. The members 9 register with the grippers 16 and are retracted as the leading end of a label is engaged with the drum, the members being returned to provide a smooth drum periphery at the glue spreader 33. In an alternative form (Fig. 4, not shown) the drum 8 has a series of circumferential grooves (32) each registering with a particular gripper 16, the glue being applied to the labels in bands, and the said grooves being kept clear of glue by a series of projections (34), on the glue spreader 35. The device is incorporated in a machine (Fig. 1 not shown) wherein bottles (31) by a linear conveyor (1) are separated by a screw (3) and then fed by a star wheel (2) to a labelling turret 6. The turret passes tangentially past the transfer devices 7, 7a to a further star wheel (5) which returns the bottles to the conveyor. Pads 29 on the transfer devices 7, 7a press the labels against the bottles.

Abstract: 1407425 Electro-chemical etching KERNFORSCHUNGSANLAGE JULICH GmbH 12 Oct 1972 [12 Oct 1971] 47043/72 Heading C7B A predetermined region or regions of a metallic surface layer on a non-conducting material is electro-chemically processed by contacting with an electrically charged body or bodies of graphite immersed in or melted by electrolyte liquid, which body or bodies transfer the electrical charge necessary for dissolving the metal by producing metal ions. In use of the apparatus shown electrolyte containing suspended graphite particles is circulated by pump 12 through nozzle 10 into contact with coated workpiece 9. During passage through perforated anode 3 the particles are positively charged and transfer their charge to the workpiece to dissolve the exposed metal surface. Anode 3 forms part of an electrolysis cell 1 in which it is separated from cathode 2 by a diaphragm 4. Alternatively as in Fig. 2 (not shown) a pad (25) of graphite felt contacts workpiece (26) supported on a vibrated rod (27), the workpiece, felt connected as anode and spaced annular cathode (24) are immersed in electrolyte. Electric circuit elements may be formed by applying a resist in a determined pattern to the workpiece and removing exposed metal by the electrochemical treatment.
