A device for the treatment of a continuous fabric web with a fluid (e.g. for washing or dyeing or other impregnating treatments) comprises a pair of endless feeding and clamping members 2 adapted to hold the edges of a web 1 and convey it through a treatment device 8, and over and beyond an endless fluid-permeable conveyor 6, on which the fabric web is supported during treatment, the device 8 containing fluid spray means 9a, 9b, 9c above the conveyor. The excess liquid from each spray 9a, 9b, 9c is collected in containers 10a, 10b, 10c which are connected for recycling of the liquid in the system 10a to 9c; 10b to 9a; and 10c to 9b. The liquid from container 10a is first purified before recycling. The clamping member 2 run in guides 3 and may be transversely adjusted to accommodate differing web widths. A roller 18 ends in clamping means 2 to the web and on leaving the treatment chamber the web is released from the clamping means 2 by a roller 19. The endless feeding and clamping members may comprise chains fitted with clamps or needles.

Title: Electronic timepiece
IPC: H02P8/02
Filed: 1976-10-27
Abstract: 1524286 Electronic timepieces DAINI SEIKOSHA KK 27 Oct 1976 [4 Nov 1975]  44634/76 Heading G3T In an electronic timepiece, when restarting after setting a seconds hand to the correct time, errors due to backlash in gearing coupling a driving motor to the hands are minimized by initially applying a higher than normal frequency driving pulse train i to the motor for a predetermined time and then applying the normal drive pulses K. When a switch 4, Fig. 3, is closed, a frequency divider circuit 2 is reset and no drive pulses are produced, so that the seconds hand can be set. When switch 4 is opened, a flip-flop 7 is set and a logic "1" signal h produced by an inverter 9, blocks NOR gates; a pulse train i derived from the divider appears at terminal K of AND gate 16 and is fed to a driving circuit of the motor. After a predetermined time a NAND gate 10 produces an output pulse which resets the flip-flop 7 so that signal h becomes logic "O". Thereupon the AND gate 16 receives output signals b, c, d, j from the divider and produces a normal driving signal "K" at terminal K. For fast setting of the seconds hand, a switch 13 is closed causing the pulse train i to be produced at K, to drive the second hand at faster than normal rate.

Title: Stabilized polymers
IPC: C08G2/00
Filed: 1963-11-13
Abstract: A process for improving the thermal stability of a normally solid oxymethylene copolymer which contains, distributed along the polymer chain of oxymethylene groups, groups having adjacent carbon atoms by reaction with water and/or an organic hydroxy compound, which comprises continuously feeding the copolymer through a zone in which it is heated together with such an agent in a quantity equal to between 2 and 25% of the weight of the copolymer to a temperature above 160 DEG  C. and under a sufficient superatmospheric pressure to maintain the mixture in liquid form and thence to a zone in which the pressure is released to eliminate vaporizable materials, the liquid mixing being maintained at above 160 DEG  C. for at least one minute. The agent is preferably used in conjunction with a basic substance, e.g. ammonia.  The agent may be introduced into and heated with the copolymer during passage of the latter through an extruder.ALSO:A process for improving the thermal stability of an oxymethylene polymer by reaction with water and/or an organic hydroxy compound (see Division C3) is carried out by feeding the polymer into a one inch single screw single vent extruder having a length to diameter ratio of 20:1.  The polymer passed first through a 4.5:1 compression ration feed section having four turns with a forty mil channel depth and then through a vented mixing section having three turns with a channel depth of 220 mils.  The reactent was injected into the polymer through the vent in the mixing section by a positive displacement piston pump and the polymer-reactent mixture then passed through a reaction section of the extruder having four turns with a channel depth of 60 mils.  A valve situated between the end of the screw and the extrusion die maintained the desired pressure. Alternatively the polymer mixed with stabilizing reactant was force fed to a one inch single screw extruder having a length to diameter ratio of 20:1.  The feed section of the extruder had five turns and a channel depth of 185 mils and the polymer was thus fed under pressure in a reaction section having six turns with a channel depth of 60 mils. Following the reaction section there was a restricted section of one and one-half turns with a channel depth of 22 mils, this section maintaining pressure in the reaction section.  The polymer-reactant mixture then passed to a reaction section having four turns with a channel depth of 220 mils.  The treated polymer then passed through a pumping (or preextrusion) section having 3 1/2 turns with a channel depth of 60 mils, where the polymer was compressed to increase its density and finally extruded through a die.

Abstract: 1445141 Optical fibre bundles OLYMPUS KOGAKU KOGYO KK 26 Sept 1973 [9 Oct 1972] 45173/73 Heading C1M An apparatus for producing optical fibre bundles includes a holding block 6 for holding fibres which is located within a guide block 1 and a push rod 8 having a lower rounded end which is mounted so that it can be moved between an upper retracted position and a lower holding position within the block, and also to be pressed on to the fibres while simultaneously being moved along the fibres and then raised for the return movement. The movement between the retracted and holding position is achieved by a motor 15 acting on the rod through a rack 14 connected to a slotted arm 13. The application of pressure and horizontal movement is brought about by the rotation of a shaft 44 on which are mounted cam discs 43, 45. The cam disc 43 has two control surfaces a, b which act through a follower roller 41 carried by an arm 39, 40 pivoted at 42 to lift the push rod from intimate contact with the fibres or allow it to press down on to the fibres. A cylindrical weight 27 attached to the push rod together with a spring 28 provide the necessary pressure. The other cam disc 45 is provided with an eccentric pin 46, which acts through rod 48, rack 49 pinion 50, shaft 51 and carriage 25 to cause the horizontal movement.
