Title: Improvements in and relating to the manufacture and production of artificial threadsfrom viscose
Inventor: WHARTON JOHN
IPC: D01F2/06
Filed: 1950-08-11
Abstract: In the production of artificial threads from viscose, the formation of hard deposits on reels, godets, thread-guides and like parts of the apparatus is prevented by treating the thread, after leaving the coagulating bath, with an oil solution containing a polyethylene glycol ester of a fatty acid having not less than 11 carbon atoms or a polyglycol ether obtained by reacting 2 to 10 mols. of ethylene oxide (or 2 to 12 mols., according to the Provisional Specification) with one mol. of fatty alcohol having not less than 10 carbon atoms. The oil is usually a mineral oil such as white oil, but fatty oils (e.g. olive oil) and liquid waxes (e.g. sperm oil) are included. Specified polyglycol esters and ethers are triglycol laurate, tetraglycol oleate, triglycol lauryl ether and tetra- or penta-glycol cetyl ether.  To prevent clogging of the drip tubes used to apply the solution to the thread, the solution may be heated to 40-50 DEG  C. The oil solutions may be applied to the thread before and/or after treatment in an aqueous processing bath containing sulphuric acid and metallic salts, or before the thread is stretched while immersed in a hot acid bath as described in Specification 467,500. In the latter case, a little of the oil solution may, in addition, be added to the acid bath, e.g. 10 g. of solution per kg. of thread spun.  The oil solution may also contain a cation-active compound, including the following:-condensation products of fatty acids with alkylolamines (e.g. b -diethylaminoethyl laurate) and also the products obtained by reacting such products with an alkylene oxide; condensation products of long chain aliphatic primary amines with an alkylene oxide; and compounds of the formul  [R.NR1R11.C2H4(OC2H4)n. OH]X, R.CO(NHC2H4)n.NH2 and [R.CO(NH.C2H4)n.NHR1R11]X wherein R is a long chain hydrophobe group of not less than 10 carbon atoms, n is an integer of 1 to 5 (1 to 20 in the first formula), R1 and R11 are alkyl groups such as methyl or ethyl, and X is an anion such as Cl-, Br- or HSO4-.

Title: Improvements relating to electric fuses
IPC: H01H85/00
Filed: 1950-08-11
Abstract: 692,627. Fusible cut-outs. COX, J. E. July 19, 1951 [Aug. 11, 1950], No. 20026/50. Class 38 (i). In a cartridge fuse, end caps 4, Fig. 1, are secured on the tubular insulating casing 1 by resilient sealing rings 3 located in annular grooves 2 in the casing (or caps) and which are deformed by forcing the caps on to the casing. A helical fuse wire 12 is wound on a porcelain core 6 supported within the casing by spigots 10 formed on inner end caps 8 to which the wire is welded and which fit resiliently over re-entrant portions 9 on the end caps 4. One of the spigots 10 houses an indicator 13 of the spring-pressed plunger or explosive capsule type which is released by a subsidiary fuse wire 17, the indicator plunger 15 penetrating a perforable portion 16 of one end cap 4. The casing is filled with marble powder 20. Fig. 4 shows a modification in which packing washers 22 are compressed between the ends of the casing 1 and the end caps 4, and outer end caps 24 containing further washers 23 are pressed over the caps 4. In this embodiment the core 6 has cemented thereto sleeve terminals 25 for the fuse wire 12, said terminals fitting over inturned spigots 26 on the caps 4. An indicator housing 27 has an enlarged end 28 slit at 29 to grip internally one of the spigots 26. The indicator may have spaced rings on its outer surface, Fig. 5 (not shown), which are adapted to be engaged by spring arms to retain the indicator in its blown position. In a further modification, Fig. 7, sleeve terminals 25 supporting the core 6 are secured to the caps 4 by circlips 41 and the fuse wire comprises sections 33, 34 of different cross-section welded together in series at 35. Fig. 8 shows a fuse having two fuse wires in parallel, each formed of sections 33, 34 of different gauge supported by the filling 20. The ends of the wires are welded to thimble 36 which are a push fit on the reentrant portions 26 of end caps 4. Insulating sleeves 37 placed round the thimbles 36 prevent leakage of the filling 20. In Figs. 7 and 8 the fuses are shown without indicators.

Title: Corrosion and heat resistant machine part, particularly for gas turbines and jet propulsion equipment and method of its manufacture
IPC: F01D5/28
Filed: 1948-07-27
Abstract: Blades, nozzles or exhaust tubes for gas turbines, or other corrosion and heat resisting machine parts, made of sintered molybdenum or tungsten, or an alloy or mixture of these, are united with a protective coating of aluminium or aluminium oxide. If an alloy is used, preferably containing 40-60 per cent molybdenum, balance tungsten, the powdered mixture of the two or the powder of pre-alloyed metal may be compacted and sintered. The machine part, after cleaning by dipping in molten potassium hydroxide, is dipped in molten aluminium or placed in a vacuum in which aluminium is heated to vaporization point; the aluminium may be deposited in layers. Heat treatment is then applied so that the deposited aluminium diffuses into and alloys superficially with the tungsten or molybdenum and subsequently the aluminium is superficially oxidized. If the sintered part is somewhat porous, the pores may be filled, before coating, with a metal, such as silver, nickel or titanium, which alloys easily with tungsten or molybdenum and is of lower melting point.  The Specification as open to inspection under Sect. 91, also describes depositing chromium, titanium or silicon by vaporization of these metals or their volatile compounds or mixture of these, the deposit consisting of a single mixed or unmixed layer, or alternate layers of individual metals.  Borides of titanium or chromium may be deposited electrolytically, preferably after the part has been coated with nickel, by inserting it in a mixture of titanium or chromium oxide, boron or boron oxide and calcium chloride, calcium oxide and/or ferrite. This subject-matter does not appear in the Specification as accepted.

Title: Method and Apparatus for Adaptive Control
IPC: G05B13/04
Filed: 1967-05-01
Abstract: 1,189,493. Adaptive control; fluid-pressure servomotor systems. FOXBORO CO. May 1, 1967 [May 23, 1966], No.20126/67. Headings G3P and G3R. In an output error-actuated control system for a process dependent on the value of an input variable, the error selectively controls, in dependence on change of the input variable or the process output, a parameter of one or the other of two different mathematical terms of a model function generator controlling the process in dependence on the value of the input variable. In Fig.1, a signal 17 corresponding to the rate of feed of a variable supply 12 to a process 11 is applied through a linear function generator 20 to control, by means of a valve 18, the rate of feed of another supply 13 in such sense that a condition of the process is maintained constant at a desired value by feedforward control. The condition is measured at 15 and compared with a desired value set at 31 so that, at low rates of feed of supply 12, any error, integrated at 28, is corrected by biasing the feedforward system at 22. Higher rates of feed of supply 12 cause operation of a relay 35 so that the error, which is then integrated at 27, is corrected by adjustment of the gain of the feedforward system at 21 The arrangement relies on variations of supply 12 to overcome the differential of relay 35 and cause alternate adjustment of controls 21 and 22 until function  generator 20 represents a model of the process. Separate switches operated at different levels of signal 17 may be used instead of relay 35. An arrangement is described in which the integrators are motor-operated potentiometers associated with capacitive feedback and the relay changeover, which occurs when the uncontrolled feed increases at a predetermined rate, is determined by resistancecapacity rate and delay circuits. In another arrangement, the bias of the function generator is controlled by the error signal and the gain is controlled in dependence on a comparison between the rates of change of the uncontrolled supply and the setting of the controlled valve which are detected by band-pass filters. In this arrangement there is provision to render the gain control ineffective when the rates of change fall to low values, to eliminate the effect of noise. Arrangements are also described in which a third integrator, supplied with the error signal under appropriate conditions, either controls a square law function in generator 20 to provide a non-linear effect, or controls the gain of another rate of feed signal where there is more than one uncontrolled feed to the process. Arrangements are also described in which the input variable is the output of a device which varies the process according to a predetermined programme. In an entirely pneumatic arrangement, Fig. 5 (not shown), one or other of the parameters of the model is adjusted by the error through a corresponding proportional plus integral bellows type controller which is rendered effective with delay by a valve operated by a pneumatic logic circuit responsive to rate of change of the input variable.

Abstract: 795,031. Ohmic resistors. BRITISH SCIENTIFIC INSTRUMENT RESEARCH ASSOCIATION, and MARTIN, S. May 11, 1954 [July 24, 1954], No. 20574/53. Class 37. [Also in Group XXXVIII] A humidity sensitive resistor comprises a porous, sintered, inorganic body having a dry state resistivity of 10<SP>6</SP>-10<SP>10</SP> ohm cms. The resistor may be prepared by mixing titanium dioxide with distilled water, making into slabs, firing in an oxidizing or inert atmosphere at 900 to 1100 C. to sinter the material, and then reducing it to the blue semi-conducting form by heating at 400 to 900 C. in a reducing atmosphere. Alternatively carbon may be mixed with the titania which is sintered in a non-oxidizing atmosphere and then the carbon is burnt away in an oxidizing atmosphere. The elements may be exposed to humidity changes for a period, to stabilize the humidity-resistance characteristic. Humidity may be measured by connecting the element in series with an A.C. source and a current meter, and further resistors may be added in series or parallel arrangement to modify the characteristic. Conducting films may be fixed on the elements to provide terminals. The porosity should be such as to provide at least ¢ per cent change in resistance in response to a 1 per cent change in relative humidity at 30 per cent, and also preferably at 10 per cent relative humidity levels.
