Abstract: 1,233,228. Multiplex radio signalling. WESTERN ELECTRIC CO. Inc. 17 Sept., 1968 [22 Sept., 1967], No. 44136/68. Heading H4L. In an electromagnetic wave transmission system a receiver for an intelligence signal and a pilot signal, having respective polarization orientations, comprises means for deriving an error signal in accordance with any angular misalignment of the pilot signal orientation, said error signal controlling a polarization rotating means which corrects the misalignment of both signals. As described, a station 29, Fig. 3, communicates over a two-way transmission path with an identical station 30. At the station 29 intelligence signals of a polarization orientation A, are generated in a unit 77 and are combined in a coupler 69 with pilot signals of the same polarization from a generator 72. The combined signals are supplied via a circulator 73 to a first input of a polarization coupler 75. Intelligence signals of a polarization B generated in a unit 78 are supplied via a circulator 74 to a second input of the polarization coupler 75, and output from the coupler is transmitted to the station 30, where the components are received with polarization orientations C, D, corresponding respectively to the orientations A, B, unless misaligned owing, for example, to swaying of aerials. At the station 30 a polarization coupler 75 splits the received signals into C and D components, the former of which is coupled via a circulator 73 to a first port of a polarization coupler 76. The D component follows a similar path via a circulator 74 to a second port of the coupler 76. The C and D components are recombined and appear at a third port of the coupler 76, whence they proceed to a reflective rotator 70 (such as a Faraday rotator which is short-circuited at its far end). Any correction for misalignment is applied in the reflective rotator, and the components re-appear in the waveguide 86, are split by the polarization coupler 76, and follow respective paths comprising for the C component the circulator 73, a coupler 69, and an intelligence signal receiver in a unit 77, and comprising for the D component the circulator 74, a coupler 71, and an intelligence signal receiver in a unit 78. The couplers 69, 71 separate out the pilot signal components appearing in the waveguides 81, 88 and apply them to a detector which provides a signal to control the reflective rotator 70. The detector (Fig. 2, not shown) may comprise a hybrid having as inputs amplified I.F. signals derived from the pilot signal outputs of the couplers 69, 71, the outputs of the said hybrid being respectively the sum and the difference of its inputs. These are detected by envelope detectors, and the difference of the detected signals is proportional to the angle of misalignment, and is the required error signal. In another embodiment (Fig. 1, not shown) a one-way transmission system is described. At the receiving station a through-type rotator is provided directly following the aerial.

A soaking or reheating pit furnace has three burners in one end wall above a flue gas outlet duct, the two outer burners being of the high velocity type and having a full load joint output not exceeding 20% of the total burner full load outputs, so that under low furnace heat requirement conditions: they may continue to fire at their full load rates, the other burner being turned off. The combustion gases leave the high velocity burner nozzles at velocities greater than 70 metres/sec., preferably greater than 90 metres/sec., thereby entraining and recirculating gases already in the furnace to provide uniform temperature conditions throughout the furnace. Preferably, the two high velocity burners have a combined full load output of 10 to 15% of the total burner outputs at full load. When the furnace heat requirements are below the high velocity burners joint outputs, these burners are cyclically switched on and off.

Abstract: 1,264,928. Treating polyester textiles. KURARAY CO. Ltd. 19 March, 1970 [20 March, 1969], No. 13257/70. Heading DIP. A polyester material is treated with a silane of the general formula where R<SP>1</SP> is or contains a vinyl, epoxycycloalkyl, glycidyl, acryl, methacryl or alkylene diamine group; R<SP>2</SP> is hydrogen, a C 1-4  alkyl group or a C 1-4  alkoxy alkyl group; R<SP>3</SP> is a C 1-4  alkyl group and n is 0 or 1, and the polyester material is subsequently treated with a resorcinol-formaldehyde latex (RFL) before being used to reinforce rubber. Examples of the polyester are high molecular weight polyesters obtained from α-# glycols and dicarboxylic acids, e.g. ethylene glycol and terephthalic acid. Examples of silanes which can be used are: vinyl triethoxy silane, vinyl tri (#-methoxy ethoxy) silane #(3,4 epoxycyclohexyl) ethyltrimethoxy silane, y-glycidoxypropyltrimethoxy silane, γ-methacryloxypropyltriemthoxy silane; N-(dimethoxymethylsilylpropyl) ethylene diamine, N-(trimethoxysilylpropyl) ethylene diamine and water-soluble condensation products thereof. The silane is applied to the polyester, by impregnating or coating, as a liquor which contains 0.3-10% by weight of the silane. Preferably the application is followed by heat-treatment at 150-240C for 0.01-300 secs. After stretching, the filaments are passed through a heating chamber. A lubricating agent, e.g. the treatment liquor, or/and spinning oil, is usually applied to the filaments before entering the heating chamber. A RFL is then applied to the treated polyester as an aqueous emulsion of the partially condensed resorcinol-formalderesin, a latex of vinyl pyridine and a natural or synthetic latex. Then the applied RFL is cured for 5-120 secs. at at least 200C.

In a dialysis process, involving the use of negative pressure and the recycling of part of the spent dialysis liquid, e.g. haemodialysis in an artificial kidney unit 10, the liquid to be dialysed, e.g. blood, passes through a tubular coiled membrane in the kidney unit via inlet and outlet ports 18, 20 whilst the dialysis liquid is drawn between the coils of the membrane via influent and effluent conduits 46, 52 by means of a constant speed vacuum pump 57. The negative pressure employed can be adjusted by a valve 60. Part of the spent dialysis liquid is wasted through a pipe 72 whilst the remainder passes to the influent conduit 46 where it is mixed with fresh dialysis liquid, added via valve 82. The rate of addition is equal to the rate of wastage of the spent dialysis liquid. A pump 90 causes the dialysis liquid to be agitated in the region of the kidney unit. The kidney unit is as described in Specification 1,175,267.

Abstract: 1288853 Acoustic flowmeter; transistor amplifiers and detectors; transducers SCARPA LABORATORIES Inc 13 April 1970 [23 Dec 1969] 17505/70 Headings H3T H4D and H4J Fluid flow in a pipe is monitored by a transducer removably applied to the outside of the pipe to pick up acoustic signals generated by shearing action in the fluid, the transducer output being amplified, frequency filtered and integrated to reject spurious transient signals. The transducer of Fig. 2 comprises a wafer 2 of piezoelectric crystal or ceramic material (examples given) bonded to the base of a housing 3a (materials and constructional details given). A worm-drive hose clip 7 (Fig. 4) clamps the housing to pipe 10, acoustic coupling being provided by, e.g. silicone putty 9 or epoxy or a contoured face of the housing. A magnetostrictive transducer may be used instead. The transducer may have a broad band response extending from audio to at least 100 kHz, or may be tuned to a narrow range within the band 10 kHz to above 100 kHz.  The circuit of Fig. 6 comprises amplifier stages Q1-Q4 with a band-pass response substantially flat between a low-frequency cut-off in the audio range (e.g. 200 Hz up to 40 kHz) and a high frequency cut-off in the range 90-100 kHz. The low cut-off is determined partly by impedance mis-matching, at low frequencies, between the transducer impedance and the input impedance of stage Q1 (which includes a bootstrap capacitor 25). Diode-connected transistor 71 provides D.C. restoration of the output of stage Q4, which is rectified in zero-bias stage Q5 and then integrated at 83, 87, 89 to give an output voltage for utilization. This output voltage is stated to be a square root function of the fluid flow rate. The integration time constant (1/10 to 2 seconds) reduces the effects of transient signals on the output voltage, which is utilized for at least one of the functions including indicating (on meter 92), recording, timing, controlling the fluid flow, and actuating an alarm. The circuit may alternatively be sharply tuned to the band 90-100 kHz when using a tuned, narrow-band transducer.
