Patent GB-1306323-A (GB)
IPC: D04H3/16
Filed: 1971-04-19
Abstract: 1306323 Stretchable bonded fabrics MONSANTO CO 19 April 1971 [2 Feb 1970] 20709/ 71 Heading D1R A nonwoven web of continuous non elastomeric filaments, partially autogenously bonded at their crossover points, so as to permit a degree of filament rotation about the bond, is stretched along a given direction so as to straighten and align filaments in that direction whilst buckling filaments in transverse directions and the bonding completed whilst the web is under tension. The fabric is thereby made stretchable up to an extension of 32% in the direction perpendicular to the applied stretch, since the buckled filaments straighten under slight tension. In examples 2-4 extruded nylon 66 filaments or ribbons 11 were stretched by aspirator 12 and deposited on foraminous belt 14 by means of vacuum source 18. The web 17 is treated with hydrogen chloride or other gas in box 29 to break hydrogen bonds and drawn 1.5 times or 1.1 times between pressure rollers 30, 31 one or both of which may be heated to produce partial bonding and pulleys 36, 37, which have a greater peripheral speed. Heater or water bath 34 desorbs the gas, so that intra-fibre hydrogen bonding occurs. In example 5 the web 17 comprised a mixture of nylon 6 and nylon 6.6 filaments and gas box 29 was replaced by an oven at 200C, which softened the nylon 6 filaments. The web was drawn 1.5 times and cooled by forced air after exiting from heater 34. In example 6 spunbonded webs of trilobal crimped or uncrimped continuous polyester filaments, were stretched 1.8 times whilst in a 210C oven, then rapidly cooled. In example 7 a spunbonded fabric of filaments having a nylon 66 core and a nylon 6 sheath which has been melted to act as a binder is drawn 1.2 times in a 175C.

Title: The manufacture of intermediate compounds for the production of colouring matters
IPC: C07C37/045
Filed: 1922-07-29
Abstract: m-Chlor-, m-brom-, and m-iodo-phenol are prepared from the corresponding m-halogenated anilines by diazotizing and decomposing the nitous-acid-free diazo solution under such conditions that the m-halogenphenol is removed from the reaction liquid by steam distillation with such rapidity that combination with more diazo compound is prevented.  In an example a cold paste of m-chloraniline sulphate crystals is diazotized leaving part thereof unchanged, stirred for about two hours and filtered from the excess amine sulphate; the diazo solution is then dropped into a vessel containing boiling dilute sulphuric acid, or even water, through which steam is blown to distil off the m-chlorphenol as it is formed. Specifications 7233/97 and 9675/04 are referred to.

Title: Improvements in impulse repeaters, particularly for telephone systems
IPC: H04Q1/36
Filed: 1924-09-08
Abstract: 222,847. Western Electric Co., Ltd., (Assignees of Miller, O. R.). Oct. 6, 1923, [Convention date]. Automatic exchange systems.-A repeater R is associated with a group selector S in order to convert irregular dialled impulses into impulses of uniform duration. The repeater may be connected to the calling line over a line switch or line finder and to the group selector over a trunk finder. The impulse relay IR upon energization connects up relays 7, 8 in series and closes a charging circuit for a condenser 9. Relay 8 operates relay 10, which locks under control of relay 11, connects up relay 12, and closes a bridge through the left winding of relay 13 and retardation coil 14, so that the line relay 17 of the selector S energizes and operates relay 18, which connects up the right winding of relay 13 in opposition to the left winding. Relay IR falls back in response to the first impulse, and relay 7, which is quick to release and slow to operate, short-circuits the left windings of relay 13 and coil 14 to reduce the resistance of the circuit of relay 17 during the impulse train, while relay 8 which is slow to release remains held during the train. Relay 11 operates during the momentary discharge of condenser 9, releasing relay 10 which opens the circuit of relay 17 at contact 19. Relay 12 relapses after an interval dependent on a shunt resistance 36 and re-operates relay 10 to re-close contact 19. At each release of relay 10 a holding ground is supplied to relay 8, which also shortcircuits relay 7. Relay 13 energizes upon reversal of line current at the connector and connects up switching relay 24. Condensers 32, 33 are used to complete the line circuit when relay 24 does not operate e.g. on free calls.

Title: Improvements in or relating to the preparation of polyvinyl acetals
Inventor: KAUFMAN MORRIS
IPC: C08F8/28
Filed: 1953-08-05
Abstract: Polyvinyl acetals are prepared by polymerizing a vinyl ester in an aqueous medium in the presence of polyvinyl alcohol containing 8 to 50 molar per cent of residual acetate groups and of a catalyst so as to produce a suspension of discrete particles of polymer, if desired removing part of the water, dissolving the residual wet polymer in situ in an organic solvent other than an aldehyde or ketone, which solvent is completely miscible with water and treating the solution so formed in situ with an acid catalyst and an aldehyde or ketone. Specified are polyvinyl formal and acetate, benzoyl peroxide as catalyst, acetic acid, methanol and ethanol as solvents and sulphuric acid as acid catalyst.  The water may be varied by allowing the suspension to settle and drawing off the supernatant liquid.  The acid catalyst and the aldehyde or ketone may be added simultaneously to the polymer solution and the mixture reacted at between 50 DEG  C. and the boiling point of the solvent, or the aldehyde or ketone may be added after the temperature of the mixture has been raised to 50 DEG  C.

Filed: 1966-07-21
Abstract: 1,199,931. Fluid logic. MINISTER OF TECHNOLOGY. 21 July, 1967 [21 July, 1966; 10 May, 1967], Nos. 32771/66 and 21649/67. Heading G4P. [Also in Division H3] A fail-safe logic arrangement comprising negatory gates has the circuit elements repeated so that, if there are k inputs and r circuit elements nominally performing the same function and giving nominally the same output, each input is split up into r nominally identical inputs and fed separately to each of the r circuit elements, the latter therefore receiving k times r inputs each. The invention is applicable to NOR and NAND gates (k = 2 or more), to bi-stable circuits comprising cross-coupled NOR gates (k = 1), and to other combinations of NOR and NAND gates. In the case of a NOR circuit a spurious " 1 " signal is undesirable, and if a short-circuit in a component would produce such a signal the component is replaced by r similar components in series. If an open-circuit would produce a spurious " 1 " signal the r components are connected in parallel. Similar considerations apply to a NAND circuit where a spurious " O " signal is undesirable. The invention is described in connection with electrical circuits (see Division H3) but may also be applied to hydraulic and pneumatic circuits where the components are resistances formed by passages or orifices.
