Abstract: 1404239 Semi-conductor gating and limiting circuits RANK ORGANISATION Ltd 19 Sept 1973 [25 Sept 1972] 44207/72 Heading H3T An input signal is blocked if it changes too fast or its amplitude falls the wrong side of a reference voltage. The reference threshold is set at 27, and if the input amplified at 15 falls below this threshold, the output of an amplifier 25 goes negative to turn off F.E.T. 18, which normally passes the signal to output amplifier 20. F.E.T. 18 is alternatively turned off by a negative output from differentiator 14. Amplifier 30 has one input slowed by C34, R33 so that the inverting input operates first on a signal change followed by the non- inverting input; this gives a waveform (Fig. 2c, not shown) equivalent to differentiation. Diodes 36, 37 and amplifier 35 full wave rectify the output of 30.

Title: Polyamide polymerisation control
IPC: C08G69/00
Filed: 1970-09-17
Abstract: 1321461 Liquid level indication FIBER INDUSTRIES Inc 17 Sept 1970 [23 Sept 1969] 44399/70 Heading G1H [Also in Division C3] Apparatus for a polyamide continuous polymerization process comprises coiled-tube reactor 18, heated to #10C above the polymer m.p.; for nylon 6, 6, 285-290C is the preferred temperature. The internal diameter of the tube increases progressively or stepwise towards the outlet. The water in the fed solutions rapidly volatilizes with the production of superatmospheric pressure, e.g. 14-15 atmos abs. The pressure decreases along the tube so that at coil exit 24 pressure may be # atmospheric. The molten polymer is collected in melt-pool 26. The level 30 at which the meltpool is to be maintained is determined from the necessary hold-time, which itself is dependent on required AEG level and on # rel,  which may be e.g. 25-70. Hold-time may be 5-30 minutes. The reactant(s) are fed to a polymerization zone (Z), the molten polymer formed being collected in a holding zone (H). The level of polymer in zone (H) is detected by passing radiation through (H). The reactants are supplied at one of at least 2 feedrates. When a higher level is sensed, the lower feedrate is initiated, and vice versa. The proportion that the reactants bear to each other is the same in each feedrate; but during the lower feedrate an additional amount of water is fed to zone (Z), this amount of water being proportional to but not exceeding the difference in the amounts of water supplied in the feed at each of the two rates. The reactants may be fed to zone (Z) as aqueous solutions or dispersions. During the lower feedrate, the additional water may be fed separately to (Z), or may be supplied by varying the concentration of the aqueous reactants. The difference in feedrates may be 0À1 - 10 per cent wt. based on the non-aqueous components of the feed solutions. The amount of additional water supplied may be 40-95% of the difference in the amounts of water supplied at the two feedrates. The radiation may be X-rays, U-V light, or #- or y-radiation, and may be supplied by radio-active Cs 137 or Sr 90. The reactants may be hexamthylene diammonium adipate and hexamethylene diamine; other monomers are listed. Delustrant TiO 2  may be present, as may acetic acid. Reference has been directed by the Comptroller to Specification 924, 630.

Patent GB-1591469-A (GB)
Title: Strapping machines
IPC: B65B13/18
Filed: 1977-10-28
Abstract: This tying-round machine has a device for combined torque sensing for fault elimination and for stopping the band (20). If a free band end (30) causes an obstruction in a band groove (16) surrounding an article (22) to be tied round, the additional resistance is transmitted to a feed wheel (28) which must be driven by a higher torque. By a suitable choice of a prestressing spring (50), the force on the driving plate (48) can be calculated so that the prestressing spring (50) comes loose from the plate (47) under an increased torque. After one revolution, a projection (53) of the plate (47) engages again into a recess of the driving plate (48). If the obstruction is still present, the plates (47, 48) come loose once more. To stop the band, a lifting magnet (66), which is connected to a detent pawl (38) via an arm (70), is provided. The lifting magnet (66) is actuated as soon as the free band end (30) reaches a sensing device (34). <IMAGE>

Abstract: 1,004,268. Moulding. SOC. DES MATIERS PLASTIQUES M.R.B., and D. BESSON. Dec. 15, 1961, No. 45027/61. Heading B5A. A process, for moulding thin walled plastics articles, part of the outside of which have textile material incorporated therein, comprises, arranging the layer of textile material over a perforated part of the mould, bringing the wall of the mould into contact with the plastics material in the fluid and polymerizable state, partially polymerizing with heat the plastics material which is in contact with both the mould and at least the marginal zone of the textile material until a solid film is formed, draining away the excess fluid and then completely polymerizing with heat the film and separating the finished article from the mould. The composition of a suitable material, consisting of a plastisol-mainly polyvinyl chloride and diethyl hexyl phthalate-, stabilizer and colouring agent, is given. Plastics materials which become cellular during the final polymerization may be used. For dip moulding, the mould 1 has holes 5, a groove 10, and a strip of cloth 15 tightly fitting into a groove 14 in the mould and having wires 16 detachably to hold the textile material 4. A sheet 17, of regenerated cellulose, polyethylene, polyester, or polyvinyl chloride is placed over the textile material. The mould is heated to 180-190‹ C., immersed in the plastics material, till it is covered with a solid film, withdrawn and left to drip and then put in an oven. The article is removed from the mould by turning it inside out. Alternatively, the textile material may be put in a perforated recess in a mould or on a grid forming the base of a mould. The inside walls may be covered with a wax or a silicone to facilitate the removal of the finished article. The mould, filled with the fluid plastics material, is put in an oven for a minute, and after pouring off the non- solidified material, is replaced therein. A screen 9 (Fig. 2, not shown) which covers the centre of the textile material may be used so that only the periphery is coated. Alternatively, the screen may be raised by legs above the textile material so that a predetermined thickness of the coating covers the textile material. A groove in the mould may form a plastic braid surrounding the edges of the textile material. The surface of the moulds may be smooth or comprise a relief pattern, e.g. that of leather. The fluid plastic material may be applied by other methods, for example by a spray gun.

Abstract: 1488854 Separating liquids MINNESOTA MINING & MFG CO 18 Oct 1974 [19 Oct 1973] 45276/74 Heading BID A dispersion of one liquid in another (e.g. oil in water) is separated by passage through an element 14 comprising alternate sections of coalescing medium 15 and sorbing medium 16, the continuous phase flowing mainly through medium 15 which forms continuous paths from the inlet end to the outlet end of the element. The dispersed phase accumulates in the sorbing medium 16. which is preferentially wet thereby. When the medium 16 is saturated the element may be discarded or reconditioned by solvent washing or squeezing. Alternatively the flow of liquid is maintained after saturation, and the dispersed phase emerges from the medium 16 as large globules and is separated from the continuous phase in a downstream gravity separator. Fig. 2 shows a multi-layer sandwich of alternate layers of media. Figs. 4, 5 (not shown) illustrate a sandwich of annular discs forming a tubular element for inward or outward flow. Fig. 3 (not shown) illustrates a spirally wound, axial flow element of two media on a central tube which carries filtrate. In Fig. 6 (not shown) the element comprises a random assembly of pieces of the two media between flat meshes (38). In all cases the media are compressed when inserted in housing 10. Exemplified coalescing media are resin-bonded glass fibres, foam plastics and natural or synthetic fibre webs. Sorbing media are preferably webs of polyethylene, polypropylene, polystyrene, polyester and polyamide fibres of diameter less than 20 microns formed by melt blowing, or porous polystyrene spheres. The coalescing and sorbing media in an element may be chemically identical but the coalescing medium has a lower flow resistance. Dimensions of the elements and layers therein are exemplified.
