Title: Pipe lining
IPC: F16L59/02
Filed: 1971-11-05
Abstract: 1357355 Lining conduits INSITUFORM (PIPES & STRUCTURES) Ltd 2 Nov 1972 [5 Nov 1971] 51492/71 Heading F2P A method of lining a conduit 70 carrying a flowable medium comprises inflating a flexible tubular liner against the surface of the conduit, the liner including a fibrous sheet structure impregnated with an uncured synthetic resin, and curing or allowing said resin to cure, whilst allowing the flowable medium to pass through the inflated liner and thus reducing the time the conduit is out of commission during the lining operation. Liner construction.-In the embodiment described the liner comprises inner and outer polyethylene layers 16, 26 and an intermediate fibrous layer 12, and is formed (Fig. 1, not shown) by wrapping a fibrous web around a flattened poylethylene tube, needling the overlapped edges of the web together, enclosing the composite flattened tube between two sheets of polyethylene and bonding the edges of these sheets together as at 28. Alternatively the fibrous web may be helically wound on to an inner tube supported on a mandrel. The fibrous layer may be a felt of polyester, nylon or acrylic fibres, optionally reinforced with filamentary material, or a glass fibre mat or rovings. The inner and outer layers 16, 26 may alternatively comprise cellulose nitrate, P.V.C., rubber, neoprene or polyester film. The fibrous layer is preferably impregnated manually with polyester or epoxy resin after formation of the liner by making cuts in the outer layer 26, injecting the resin into the fibrous layer, applying adhesive patches to the cuts and then passing the liner through rollers to distribute the resin (Fig. 4, not shown). Lining operation.-A length of liner is winched into the conduit and inflated by a pump 92 via a hose 88. Once the liner is inflated an orifice 94 may be opened to produce a through flow of air and prevent a build up of heat in the liner if the curing reaction is exothermic. The upstream and downstream ends of the liner are closed by a flap valve and weight respectively (Figs. 7 and 8, not shown) which permit the passage of the medium normally flowing in the conduit but prevent loss of the inflating air. In an alternative embodiment the flowable medium may be passed through the liner via a pilot tube that is removed after the resin of the liner is cured. To accelerate curing of the resin the liner may be inflated with steam.

Title: Q-switched lasers
Inventor: MACKINTOSH IAN WINSTONE
IPC: H01S3/11
Filed: 1968-11-04
Abstract: 1,248,405. Lasers. DEFENCE, SECRETARY OF. 30 Oct., 1969 [4 Nov., 1968], No. 52188/68. Heading H1C. Laser Q-switching is effected by periodically varying the optical spacing between the plates of a Fabry Perot etalon forming one of the resonator mirrors. As shown in Fig. 1, a neodymium-doped yttrium aluminium garnet laser rod 1 is located in a resonator comprising a dielectric mirror 3 and a Fabry Perot etalon 6 formed by dielectric mirrors 7a, 7b, the optical spacing of the etalon being determined by a hollow piezo-electric cylindrical transducer 9. The optical spacing is varied periodically by a pulse generator 27 and the mean spacing is determined by a D.C. bias from an amplifier 25. This bias is adjusted to maintain the etalon optical spacing constant by superimposing a 70 Hz. modulation from an oscillator 23, the modulated laser output being detected by using a beam splitter 13 and a photo-diode 15 so as to produce a feedback signal which passes through a pulse stretcher 17 and a tuned amplifier 19 to a phase-sensitive detector 21. If the phase of the feedback signal differs from that of the oscillator 23, the detector 21 adjusts the D.C. bias to a compensating level. A modified laser is described, Fig. 2, in which two Fabry Perot etalons are used, one etalon 33 having a fixed optical spacing and being located within the resonator, while the other etalon 35 functions as a variable resonator mirror and consists of dielectric mirrors 37a, 37b on flats 34, 36 adjustably spaced by a transducer 41. Etalon 33 is inclined with respect to the optical axis to reflect light of certain frequencies out of the system which might otherwise give rise to laser action at those times when etalon 35 is non- reflective. The combination of two etalons 33, 35 effects laser action by the change of optical spacing of one etalon relative to the other, a laser pulse being produced each time a spacing relationship is obtained in which etalon 33 is transmissive and etalon 35 reflective. Continuous pumping may be used. Instead of altering the physical distance between etalon mirrors, the optical spacing may be varied by change of refractive index using the electrooptic effect.

Title: Improvements in or relating to slewing jib cranes having safety apparatus
IPC: B66C15/04
Filed: 1968-11-05
Abstract: 1,218,798. Slueing jib cranes. JOHNSON & WAYNE Ltd., and H. W. SIMPSON. 3 Nov., 1969 [5 Nov., 1968], No. 52283/68. Heading B8B. A jib crane (not shown) is prevented from slueing into a predetermined sector by safety means which interrupt the operation of power slueing means and initiate the operation of braking means. Fig. 2 shows at P, Q the slueing ones of two tower cranes with working areas PRS, QRS overlapping in the cross-hatched area SR. Each crane has an infra-red transmitter and an infra-red receiver, the former transmitting only when the associated jib is outside the respective sector PRS, QRS. The arrangement is such that when one jib is in the sector PRS, QRS and the other jib is slued so as to bring it into the sector QRS, PRS its slueing power is cut off and its slueing brake applied, through a control circuit, Fig. 3 (not shown). This arrangement is suitable when the jibs are at the same height, but is unduly restrictive when one jib is higher than the other when a modified circuit, Fig. 4 (not shown), allows full slueing when the saddle of the higher crane jib covers only the area MNQ within the sector QRS. Audible warning is given by an alarm bell and the encroaching jib may be slued back out of its predetermined sector. The alarm bell sounds when the operator locks the jib against slueing so as to pass safely through the slueing section to ground where switching off the power releases the braking means and turns off the alarm, while allowing the jib to slue in the wind. Braking means may be provided by passing direct current through the stator and the rotor of an induction motor used for slueing the jib.

Filed: 1971-11-12
Abstract: 1374447 Automatic control systems ROBERT BOSCH GmbH 12 Nov 1971 [16 Nov 1970] 52559/71 Heading G3R [Also in Division H2] A speed regulating circuit for a linear motor 11 having primary windings 12, 13, 14 and a secondary section formed by a rail 16 comprises thyristor switching stages 24, 25, 26 controlling the voltage applied from A.C. mains 17, 18, 19 to the windings 12, 13, 14, an eddy current brake 15 supplied from a phase of the mains through a thyristor switching stage 27, pulse control stages 30, 31 controlling the stages 24--27 and control stages 32, 33 which control the stages 30, 31 and are controlled by difference signals from comparison stages 35, 36 which respectively receive a reference signal from potentiometer 38 and a signal from tachogenerator 29 representing the speed of the motor, and a reference signal from potentiometer 37 and a signal from circuit members 28, 34 representative of the braking current. Members 37, 38 may be adjusted to produce two sets of characteristics relating motor'driving force and speed, each set being respectively obtained by variation of the voltage applied to the windings 12, 13, 14 and the current supplied to the brake 15, Fig.3 (not shown). Various ranges of operating speed corresponding to the selected characteristics may be obtained and a modification suitable for very low crawl speeds is described, Fig.2 (not shown) in which the stage 36 is supplied directly from the potentiometer 38 and from the tachogenerator 29 (members 28, 34 being omitted) and the stage 35 is supplied from a potentiometer (44) equivalent to potentiometer 37 and from a circuit (41, 42) sensing the voltage applied to the winding 12. Optimum control may be obtained by designing the stages 32, 33 as PID controllers, the circuit arrangement and operation of such a controller being described, Fig.4 (not shown). The members 37, 38 may be replaced by a single reference source common to both stages 32, 33 which are then designed so that the proportional share of the control characteristic is adjustable. Current transformer 28 may be replaced by a current-sensing resistor and main switches 20, 21, 22 provide for phase interchange to reverse the motor.

Title: Improvements relating to apparatus for discharging sewage and/or industrial waste from a tank
IPC: F04D9/04
Filed: 1965-12-10
Abstract: 1,130,506. Controlling liquid level. I.C. JENNINGS. Dec.10, 1965 [Dec.11, 1964], No.52586/65. Heading G1H. [Also in Division F1] In a liquid level control system, a centrifugal pump 46, Fig. 3, is operated to discharge liquid waste from a storage tank 42 when the liquid level is sufficient to prime the pump and to raise a float 60, Fig. 4, sufficiently to switch on the pump driving motor. The float chamber 52 and switch 65 are arranged on the discharge side of the pump. To permit the liquid to rise up the tank discharge pipe 45 when the pump is inoperative, the pipe is vented through a pipe 48 and the gravity supply line 40. When the pump has discharged sufficient liquid to uncover the lower end of the pipe 45 the pump loses its prime and the float falls to switch off the pump. The float 60 is housed in a portion of the chamber 52 which is separated from the through-flow portion thereof by a screen 66. In a alternative embodiment, Figs. 1 and 2 (not shown), the centrifugal pump is omitted and the liquid is discharged from the tank by pressurized air supplied to the top of the tank by a liquid-ring compressor (21), the operation of the latter being controlled by a float-actuated switch arranged in a pipe section through which the tank is both filled and emptied. When the liquid-ring compressor is inoperative, the tank is vented through the compressor or a solenoid-operated vent valve. The float-actuated switch may be replaced by a pressure switch operable by the head of liquid in the chamber or discharge line.

Abstract: 1,127,262. Programmed computers. BADGER CO. Inc. 20 Dec., 1965 [18 Dec., 1964], No. 53992/65. Addition to 1,016,038. Heading G4A. In the system for producing a drawing of the layout of pipe-lines &c. in a chemical or fluidhandling plant, under the control of a computer, as described in the parent Specification (Division B), details of a suitable programme for the computer are provided. The various data regarding the positions and sizes of these items of the plant which are to be connected by piping, together with details of the positions of p pe entry and exit points, minimum clearances to be allowed (e.g. between hot and cold pipes, passageways for people and vehicles &c.) are entered into the computer from cards or tape, and converted into a form more convenient to computer operation. A memory location designated " TILT " is set at zero. This subsequently is changed to " one " if the initial tests fail to find a permissible route for a pipe. Dealing with the layout of one pipe at a time, the computer programme proceeds, as indicated in Fig. 11, to determine from the X, Y and Z co-ordinates of the beginning and end points, and from the various limits and allowances stored in the memory, whether a first route running parallel to X, Y and Z axes, in that order, is permissible. Infringements of any of the limits or requirements initiates the start of a subsequent test for an alternative route (e.g. XZY), and so on until either a permissible route is found or the six alternatives (see Fig. 8, not shown) are exhausted. In the latter event, a " one " is entered in " TILT " and this initiates a programme such as that set out in Fig. 10 which checks over the first routine and provides further alternatives to be tried.

Abstract: 540,790. Cellulose ester effect threads. KAMMER TESTVEREK TEXTILIPAR R. T., and HERMANN, L. Sept. 12, 1939, No. 25665. Convention date, Sept. 13, 1938. [Classes 2 (ii) and 15 (ii)] In the process of immunizing vegetable fibres such as cotton against dyeing by substantive dyestuffs in which the fibres are first alkalized and then esterified by sulphonic acid halides of the aromatic series such as p-toluene sulphochloride, the esterification is conducted by saturating the alkalized thread with a cold solution of the halide in an organic solvent such as carbon tetrachloride and then heating the saturated thread for some hours in the air at over 100‹C. In this manner the quantity of halide required for the treatment is economized. The excess halide solution adhering to the fibre may be removed by centrifuging, and the treatment may be carried out on the bobbin, preferably cross wound and somewhat compressed, in a container through which air currents may be passed for recovery of the solvent. A 12-15 per cent solution of the halide may be employed. The process can be employed for the protection of already coloured threads against later taking up of dyestuff.
