Title: Deflectable lip sealing connection
IPC: F16J15/08
Filed: 1966-09-06
Abstract: 1,138,876. Pipe joints; pressure vessel closures; joint-making packing. GRAY TOOL CO. 6 Sept., 1966 [9 Nov., 1965], No. 39785/66. Headings F2B, F2G and F2P. A sealing arrangement between two members wherein a flexible annular lip presenting an annular sealing surface and extending axially from the end of one member is arranged to be deflected into stressed sealing engagement with an annular sealing surface on the other member and wherein annular radial stop shoulders provided around the sealing surfaces are arranged to abut to limit the deflection of the annular lip, is characterized in that a groove is provided in at least one of the annular shoulders across the entire radial extent thereof to prevent an annular seal being formed between the abutting shoulders. As shown, two flexible annular lips 20, 22, which extend axially from opposite sides of a central radial rib 18 of a hard metal, rubber or synthetic plastics sealing ring 16, are adapted to be deflected by and sealingly engage conical surfaces 38 provided in the ends of two pipes 12 and 14 when the pipes are drawn together, as for example, by a segmental clamp 50, Fig. 3 (not shown). To prevent the formation of an annular seal between the co-operating radial end faces of the rib and pipe which act as stops to limit deflection of the sealing lips grooves 42 and 46 are provided in opposite rib faces chordally of the rib at the base of the flexible sealing lips. This arrangement enables failure of the flexible lips to sealingly engage the conical sealing surfaces 38 on the pipes to be readily detected such as by a pressure test and not to be masked by provisional or initial sealing occurring between the pipe ends and sealing ring rib. In a further embodiment, Fig. 4 (not shown), of a coupling between pipe ends, the sealing ring is omitted and a flexible axially extending sealing lip, stop shoulder, and associated groove are provided directly on one pipe end. In a similar embodiment, Figs. 5 and 6 (not shown), a seal between a closure plate and a pressure vessel is formed by providing the deflectable lip, stop shoulder and groove on the closure plate.

Abstract: 973, 089. Electric selective signalling systems. GENERAL ELECTRIC CO. Ltd. Nov. 6, 1962 [Nov. 7, 1961 ], No. 39841/61. Heading G4H. [Also in Division H4] In a pulse code modulation system sample voltages of the input signal are fed to two comparator circuits for producing pulse signals representing the sampled magnitude in digital form, and so arranged that only one comparator provides an output when the voltage is positive while the other is operative for negative sampled voltages. In a 25 channel time division system of the type described in Specification 973, 087 the input stages 43 (Fig. 4) supply each sampled signal value s over line 44 to circuits 45, 47 operating to add and subtract respectively a voltage x to the signal. The composite signals are then fed via gates 46 and 48 (operating in conjunction with channel gates) to comparator circuits 40 and 41. Reference voltages Vr, V<SP>1</SP>r corresponding to voltages +x and -x, respectively, are supplied to comparators 40 and 41, respectively, the operation of which forms the subject-matter of Specification 973,088. Comparator circuit 40 only provides output digital pulse signals when s + x is less than x i.e, for negative s while circuit 41 operates when s - x is less than -x i.e. for positive s. The output pulses of these circuits which correspond in number to the sampled amplitude are fed via gate 52 to counter 53 and the first six stages of a register 54. Depending on whether circuit 40 or 41 supplies the signal a pulse or not, as the case may be, is sent to the 7th stage of 54 by circuits 55 and 56 while the 8th stage is used for synchronization.

Title: Improving dyeing properties of polyester filaments and like structures
Inventor: KINGSTON DEREK
IPC: D06M13/372
Filed: 1961-11-20
Abstract: Polyester filaments and fibres which are dyeable with acid dyestuffs are characterised in that they have a concentric outer layer which constitutes 30 to 80% of the fibre cross-sectional area, when dyed and viewed in transverse cross-section, which is dyeable with acid dyestuffs due to the presence in said outer layer of nitrogenous compounds as a result of a treatment with specified polyamines, which nitrogenous compounds function as sites for such dyestuffs.  The treatment is effected by treating the filaments in their undrawn condition with an organic liquid comprising a polyamine, drawing the filaments 2 to 6 times their length so that not more than 20% of the cross-sectional area of the filaments is penetrated by the polyamine, as can be seen when the filaments are dyed and viewed in transverse cross-section, followed by heating the filaments in the presence of residual polyamine which is present on the filaments after drawing until a concentric outer layer of the filaments constitutes 30 to 80% of their cross-sectional area.  The polyesters may be polyethylene terephthalate or copolyesters of polyethylene terephthalate/sebacate, terephthalate/adipate, terephthalate/isophthalate, or hexa hydro-paraxylylene terephthalate.  The polyamines used are non-ionic and should have an average molecular weight of about 110 to 1000, preferably 200 to 600.  Polyamines corresponding to the formula NH2 . CH2(CH2 . O . CH2)nCH2 . NH2 where n is 3 to 12 are preferred.  The polyamines may be applied by themselves or in solution or dispersion in an organic liquid. The treatment of the undrawn filaments may be effected at 80 to 170 DEG C., preferably 110 to 130 DEG C. for periods of up to 1 minute preferably 1 to 30 seconds.  The drawing of the filaments after the amine treatment is preferably effected in water at 60 to 100 DEG C.  The subsequent heat treatment may be effected at 100 to 210 DEG C. preferably 110 to 150 DEG C. for 5 to 20 minutes duration.  The treated filaments are dyeable with acid dyestuffs such as azogeranine.

Abstract: 1,201,801. Testing cable insulation. GENERAL CABLE CORP. Sept.14, 1967 [Sept.20, 1966], No.41904/67. Heading G1U. A cable testing apparatus is of the type where the cable 1 is passed through an elongate fluid bath probe 11, and potential gradients are established along the probe between a central electrode 8 supplied with high alternating voltage and earthed end electrodes 10, two detector electrodes 12, 13 being situated symmetrically relative to the central electrode near each end of the probe. The ratio of the output pulse amplitudes obtained at the two detector electrodes indicates the position along the probe at which a corona discharge occurs within the cable, and this position indicates the corona inception voltage. To render the result independent of pulse shape, &c., the detector electrodes are coupled by a capacitor stack C5 whose electrical centre is connected to the central electrode 8, and the signals derived from the detectors are passed through the filter rectifier-amplifier chains 25A- 28A, 25B-28B, that from one electrode 14 being inverted, and applied to opposite ends of a multitapped resistor R5. The particular tapping at which zero amplitude voltage occurs along this resistor is determined and represents the corona inception voltage. To determine the position along the multi-tapped resistor where zero volts occurs, trigger circuits 33 are attached to repective tappings. The number of these which are triggered indicates the required position. This number is determined by parallelling the trigger output currents to flow through a resistor 36, the voltage across this indicating the number. This voltage, representing the corona voltage, may be displayed on an oscilloscope 40, or used to control an alarm 42 and a recorder 43.
