Title: Equalizing arrangements
IPC: H04B3/14
Filed: 1969-06-23
Abstract: 1315936 Controlling equalizers POST OFFICE 23 June 1970 [23 June 1969] 31513/69 Heading H4R Equalizers located at spaced intervals along a transmission cable can be individually switched into and out of the transmission path by signals from either end of the path. The figure shows one equalizing station connected in a cable AB. The signal is separated from the power at F and G and routed via conductors L and M through a fixed equalizer C and an equalizer D which is adjusted when the cable is installed. The signal normally by-passes a temperature compensating equalizer K via a switch (contact or electronic equivalent) S1. This by-pass path can be broken to route the signal through the equalizer K by sending a tone along the line. The tone is of a frequency individual to the station and a different transmission band is used for each direction of transmission. Each station includes filters R and N each adapted to pass one of the tones to a corresponding amplifier T or P and rectifier circuit V or Q. Reception of a tone causes a continuous signal to be applied to a switch unit S causing it to open switch S1 connecting the equalizer K into circuit. The switch S1 and the switch unit S may be diode gates controlled by a transistor circuit. In two detailed embodiments (not shown) diode gates are in the path in place of S1 and in the parallel path through K and both are controlled by a long tailed pair.

Abstract: 1318879 -Dyeing fibrous substrates IMPERIAL CHEMICAL INDUSTRIES Ltd 17 Nov 1970 [15 Sept 1969] 45291/69 Heading D1B Fibrous substrates e.g. wool, mercerised cotton and synthetic polyamides are dyed or printed with a water-soluble dyestuff containing an amino group bearing a hydrogen atom which is attached to a saturated carbon atom (i.e. a carbon atom otherwise linked only to hydrogen or to other multivalent atoms through single valencey bonds) of the dyestuff molecule in conjunction with a treatment with a heterocyclic compound containing at least one -N=C(halogen)- group. Under the dyeing, printing or treatment conditions a hydrogen atom in the amino group reacts with the -N=C(halogen)- group, to form a carbon nitrogen bond. The treatment with the heterocyclic compound may be before, with or after the dye application. Anthraquinone and azo dyes are preferred and the amino group which may be primary or secondary may be substituted on an alkyl, alkylene, an alicyclic ring or a saturated heterocyclic ring.

Abstract: 1322902 Condensers wherein vapour is condensed by direct contact with cooling medium IMPERIAL CHEMICAL INDUSTRIES Ltd 4 Nov 1970 [5 Dec 1969] 59511/69 Heading BIB [Also in Division C2] The vapour of 1,2-dichloroethane, mixed with water-vapour and non-condensable gases, is condensed without the formation of ice by passing the vapour-mixture through inlet 2 into ring-packed tower 1 which is supplied through pipe 3 with a countercurrent stream of a liquid medium, such as calcium chloride brine, at sub-normal temperature sufficient to condense both the dichloroethane vapour and the watervapour. A mixture of brine and condensed dichloroethane is withdrawn from the base of the tower through pipe 4 into separator 5. Condensed dichloroethane is withdrawn from the system through pipe 6. A small amount of the separated brine is rejected through pipe 12, and the remainder is pumped back to the top of the tower through cooler 11. Non- ccndensable gases are discharged from the tower through pipe 13. The temperature of the brine is suitably in the range 0C to -40C. and of concentration 25% to 32% Ca Cl 2 . Instead of brine, ethylene glycol may be used as cooling-liquid.

The duct 3a is sloped back to the tank 10 for drainage. The apparatus may comprise more than one chamber A, each fed from a separate supply duct and pump. The heater 12 can be controlled in dependence on the temperature of the liquid flowing through the duct 13. The pumps 14 and 4a may be interlocked. If more than one pump 4a is fitted they need not operate simultaneously. The tanks can be heated by gas flowing through pipes, and can be automatically topped up with liquid medium. The weir 8 has notches at each side, Fig. 2, not shown, to ensure that medium flowing over it is kept away from the pump inlet.

Title: Method of and devi-e for collecting samples from a particulate  stream
IPC: G01N1/20
Filed: 1969-11-26
Abstract: 1325864 Sampling particulate material FISONS Ltd 6 Nov 1970 [26 Nov 1969] 57801/69 Heading B8N A method of removing a sample from a stream of particles, e.g. a falling stream, comprises positioning a hollow sampling member to one side of the stream, the member having an aperture with a generally rectangular elevation when viewed through the stream, the aperture also having substantially zero projected area along the line of flow of the stream; moving the member along a substantially straight line through the stream with the aperture foremost so that particles are culled from the stream; and recovering the culled particles. Apparatus for use in carrying out the above method comprises a hollow sampling member 1 having a rectangular aperture 2; means 6 for moving the member with its aperture foremost through a stream 23 of particles; and means for mounting the apparatus on a duct 13 through which the stream flows. The moving means 6 is a double acting pneumatic ram although an hydraulic ram, an electrically operated rack and pinion mechanism, or a crank lever mechanism may be used. The mounting means comprises a delivery shoot 19, e.g. of stainless -steel coated on its inner surface with P.T.F.E., having a flange 11 bolted to the duct at the location of aperture 12. Guide rods 7, 8 attached to the member 1 are slidably mounted in guide tubes 9, 10 respectively. Oil-containing air exhausted from the ram 6 may pass through the guide tubes to facilitate lubrication. In use, the member is moved from the illustrated position and through the stream. Halting the member adjacent the aperture 12 will cause the sample by its inertia to pass from the member and via the shoot 19 into a bag or a device for classifying the particles according to size. In an alternative embodiment the member is positioned on rod 5 such that sampling occurs when the ram 6 is extended. The sample in this case will be delivered into a shoot positioned on the duct opposite the ram. The aperture may be curved.
