Filed: 1969-10-30
Abstract: 1,240,360. Synthetic polymer films having closed voids. NESTE OY. 30 Oct., 1969 [4 Nov., 1968], No. 53153/69. Heading B5B. Flat films containing closed voids or cells and consisting of a mixture of a synthetic organic normally non-crystalline polymeric material and at least one finely divided inorganic pigment in a proportion by weight of 1 to 200% (based on the weight of the polymeric material) are made by mixing the filler with a solution of the polymeric material in a volatile solvent or mixture of volatile solvents, producing a flat film from the solution by the known film casting process, immersing the film in a mixture of a volatile organic polar solvent which causes the film to swell but does not dissolve it and a volatile organic non-polar solvent which is miscible with the other solvent, has no solvent or swelling action on the film and which has a lower boiling point than the polar solvent and heating the swollen film whereby the solvents are caused to evaporate and the second solvent in evaporating off and in conjunction with the filler, acts as a foaming agent and causes the film to acquire a cellular structure of closed voids. The film is preferably stretched before being subjected to the heat treatment but need not be maintained under stretching tension during the heat treatment. The polymer used is preferably polyvinyl chloride. The film may contain 1 to 50% by weight of a "soft" polymer or 1 to 20% by weight of a plasticizer (based on the weight of the main polymer of the film). The inorganic filler may be finely divided talc, kaolin, one or more other clay minerals, or one or more metallic oxides, e.g. lead monoxide, aluminium oxide, or titanium dioxide. The proportion of filler in the film is preferably 10 to 100% by weight if based on the weight of the polymeric material of the film. The solvent mixture in which the film is immersed may be a mixture of a ketone and a hydrocarbon or a mixture of hydrocarbons. In an example, 10 parts by weight of polyvinyl chloride are dissolved in 90 parts by weight of a 1:1 mixture of tetrahydrofurane and methylethylketone, 5 parts by weight of finely ground talc are thoroughly mixed with the polymer solution and a film is made from the solution by the known casting method. The film is immersed for 3 minutes in a 1: 4 (W/W) mixture of acetone and pentane and thereafter heated for 45 seconds at 130‹ C. whereby a cellular structure is imparted to the film and the solvents evaporated off.

Title: Pattern dyeing of textile materials
IPC: D06B11/00
Filed: 1974-12-12
Abstract: The work is carried out with at least one row of dye nozzles which extends transversely to the direction of movement of the sheet-like textile structure, which can be a web of carpet material, pressurised jets of dye liquor issuing continuously from the dye nozzles. Each jet of dye liquor is directed either onto the sheet-like structure or away from this according to the pattern to be produced and according to the speed of movement of the sheet-like textile structure. By means of data blocks with pattern data, the selective deflection of each of the jets of dye liquor within successive cycles is controlled. Each cycle is initiated by the movement of the sheet-like textile structure over a distance corresponding to the pattern fineness. Within each cycle, the directing of each jet of dye liquor onto the sheet-like textile structure takes place only during a predetermined time interval which is followed by a rest time. During this rest time, which is at least as long as the recovery time of the dye-liquor jet deflection device composed of the air-supply lines (62) and of the solenoid valves (64), all the jets of dye liquor are directed away from the sheet-like textile structure. The proposed spray-printing process is also suitable for the printing of fine or complicated patterns. <IMAGE>

Abstract: 1427133 Selective signalling SMITHS INDUSTRIES Ltd 26 Feb 1973 [24 Nov 1971] 54677/71 Heading G4H [Also in Division H3] Apparatus for interrogating sensors 103 in units 105 and for controlling electrical devices 106 in a vehicle comprises a control unit 110 which sends and receives pulse signals of variable amplitude and width circulating in a closed loop 109. The signals take the form of successive cycles of 64 pulses, Fig. 3(a): one large-amplitude start pulse followed by 15 sensor unit (105) pulses and 48 operative unit (108) pulses, each unit 105, 108 being allotted a particular time slot in a cycle. The settings of 48 switches in a console 111 (Fig. 4, not shown) are used to control the on/off states of devices 106, and a display panel 112 (instruments and warning indicators) is provided for the sensor readings. Each sensor unit 105, Fig. 6, comprises means 122 for detecting the start pulse (sync check) and means 123-4 for counting the time slots 0-15 until the corresponding time slot occurs, when it enables a #-# modulator 126-132, Fig. 10 (not shown), and a pulse amplitude modulator 125: the #-# modulator converts the sensor reading into a stream of 1, 0 pulses which are converted into a stream of pulses such as 2 and 3 of Fig. 3. These pulses are transmitted one per cycle in the time slot for that unit (i.e. the reading is sampled once per cycle). Each of the command pulses 16-63 emerging from a modulator 119, Fig. 4 (not shown), in control unit 110 is either of full or half width (e.g. 16, 17, Fig. 3) corresponding to on/off settings of switches 111. Each unit 108, Fig. 7, comprises means 138 to determine the width of the corresponding pulse and to provide an output to a command verifier 139 (Figs. 13, 14, not shown) which checks that a change in width is accompanied by four successive pulses of the new width (one in each of the next four cycles): if so, then a bi-stable circuit 140 outputs a signal which causes a switch 141 to connect/disconnect the device 106 with/from the power supply 102. The signal from 140 also causes a modulator 136 to place a pulse in the corresponding time slot which is of either full or half amplitude to indicate that the device has been turned on or off. Pulse modulation may be effected by connecting or disconnecting a respective resistor into the loop. The sensors may monitor liquid level, temperature, pressure, velocity &c. and the devices may be, e.g. a rear screen heater.
