Title: Modification of the properties of articles derived from nylon
Filed: 1944-05-13
Abstract: Elastic articles are produced by heating undrawn filaments, bristles, yarns, films and like shaped articles derived from nylon in the presence of an alcohol, formaldehyde and/or polyoxymethylene or paraformaldehyde and a catalyst until the nylon contains at least 4 per cent of combined formaldehyde based on the weight of the nylon. The nylon is of the general type obtainable according to Specifications 461,236, 461,237, 474,999 and 495,790.  Suitable catalysts are sulphuric, hydrochloric, phosphoric, oxalic, p-toluenesulphonic, or trichloracetic acid or the ammonium salts thereof.  Suitable alcohols are methyl, ethyl, n-propyl, n-butyl, iso-butyl, octyl, dodecyl or methallyl alcohol, glycollic acid, castor oil fatty acids, cyclo - hexanol, ethylene glycol, diethylene glycol, b .b 1-dihydroxyethyl sulphide, ethylene glycol monomethyl ether, ethylene glycol monoethyl ether or benzyl alcohol. Paraformaldehyde or polyoxymethylene may be depolymerized before use, e.g. by heating in a lower aliphatic alcohol with caustic alkali, yielding an alcoholic solution of formaldehyde.  The articles to be treated may be immersed in a bath containing the aldehyde, alcohol and catalyst for 1-120 mins. at 50-110 DEG  C. and after removing surplus liquid, and drying may be baked for a few minutes at 100-150 DEG  C.  Alternatively, the articles may be immersed for 1-120 minutes at 50-100 DEG  C. in a bath containing aldehyde and then steeped in alcohol for 1-60 minutes at temperatures up to 150 DEG  C. After freeing from adherent liquid and drying, the materials may then be baked.  The catalyst in such a two-stage treatment may be added to either bath or to both.  Volatile solvents for the reagents may be present in the reaction mixture, e.g. water, ethylene dichloride, dioxan or chlorbenzene.  The reaction mixture may also contain wetting, dispersing or swelling agents.  Such agents may also be used as pretreating baths.  The treated articles may be stretched, e.g. by cold drawing.  A number of examples are given of the treatment of yarns and monofils, the physical properties of the treated articles being also given. Specifications 534,698 and 565,066 also are referred to.

Title: Improvements relating to wood finishing
IPC: B24C1/00
Filed: 1944-04-14
Abstract: Wood is treated by covering the surface with an opaque coat and then bombarding with hard particles coated or mixed with pigment powder. Preferably the wood pores are filled with a suitable wood filler which may be harder or softer than the wood 1 and then coated with an opaque enamel 6 by brushing or spraying.  This enamel coat may be bonded to the wood surface by the previous application of a primer coat.  The enamel coat is then dried and the surface bombarded by fine carrier particles 7 (e.g., aluminium oxide or silicon carbide), preferably of 120 mesh size or finer, coated with a coloured pigment 8 by a centrifugal blasting wheel (described in Specification 533,051, [Group XXIII],) 9 so as to emphasise the grain structure of the wood. This bombardment operation may take place in two stages, an initial low velocity <PICT:0582945/III/1> (5,000 to 6,000 feet per minute) bombardment, followed by a high velocity (9,000 to 14,000 feet per minute) bombardment, but the initial bombardment may be omitted.  The amount of pigment powder mixed with the fine carrier particles may be varied according to the required colour denseness of the final product. After the high velocity bombardment the pigmented surface may be coated with a transparent lacquer.

Abstract: 1506015 Controlling air supply to furnaces TABO INDUSTRIUGNAR AB 21 Feb 1975 [21 Feb 1974] 7317/75 Heading F4B [Also in Division G3] In a method of operating a waste consuming furnace, e.g. a cremation furnace, using a two phase combustion process wherein the supply of secondary air for combustion during each of the two phases is controlled according to a set programme based on time and wherein secondary air is supplied initially during the first phase and thereafter is reduced continuously to a minimum, the flue gas density in a chimney 5 is observed or sensed by means of a photoelectric cell 13 and in the event of it being too high a temporary increase in the secondary air supply is effected. An adjustable damper 4 is provided in the flue gas duct 3 to compensate for pressure changes resulting from the introduction of secondary air to maintain pressure in the combustion chamber 1 at a desired predetermined level below atmospheric pressure. As shown the secondary air is introduced into vertical channels 2 via a fan 15 and pipes 17 to provide an injector effect for the flue gases leaving the combustion chamber through apertures 16, whereby secondary combustion takes place in said channels 2 which lead into the horizontal duct 3. Signals from the photoelectric cell 13 may be used to switch the fan 15 on, or if the fan is already working, to increase the speed of the fan. Pressure in chamber 1 is sensed via a line 7 leading to a draught regulator 8 which in turn is linked to a motor 6 operating the damper 4. The fan, photoelectric cell and damper are all connected to a control unit 14 having a program mechanism 10.

Valves; valve-gear.-Relates to motor-cycle engines of the kind wherein the engine is built into the hub of a wheel, the cylinders being carried by a rotary casing, the rotation of which is transmitted to the wheel. According to the invention, the rotating cylinder casing 4 is connected by planet gearing 11, 12, 13, 14 to a rotary valve disk 5 containing admission ports 8 and exhaust ports 7. The fixed pinion 12 of the gearing is formed on the hollow non-rotating crank-shaft 2 arranged in the gear-box 1. The relative speed of the disk 5 and the casing 4 is such that the ports (one in each cylinder) of alternate cylinders, are opened to mixture and exhaust in accordance with the four-stroke cvcle. The disk 5 is hollow and forms a fuel mixture space with which the admission port 8 connects. The mixture enters the space through the hollow crank-shaft 2, the crank chamber, and passages 9. The cycle wheel 19 is driven from a pinion 15 on the shaft 6 of the disk 5 through two fixed pinions 16, 17 which gear with a toothed ring 18 in the wheel hub 10. The magneto 26 is driven from the pinion 17 through gearing 20 - - 25. The sparking-plugs 28 move past a serrated sparking-plate 29, Fig. 2, in the electric circuit, of sufficient length to permit the usual timing regulation. The magneto and an annular fuel tank 27 are arranged on the side of the wheel opposite the motor casing, to balance the latter.

Filed: 1939-03-07
Abstract: 516,410. Range-finders. SCHNEIDER & CIE., and FIEUX, J. March 7, 1939, No. 7447. [Class 97 (i)] A range-finder or firecorrection sighting device is characterised by disposing in the focal plane of a transparent reflector sight of known type, in place of the usual cross-wires, an iris diaphragm whose opening may be varied to cause the image of the latter on the glass of the sight to circumscribe the apparent contour of the object observed. In the embodiment described, the sight consists of a collimator body, in two parts 1, 1a, in which are mounted a condenser 2, a source of light 3, and an objective 5 in the focal plane of which is mounted an iris diaphragm 6 connected to a control ring 7. The driving lug 7a of the latter projects through the slot 6b and engages a recess 8 of the control lever 9 mounted by means of a circular strip 9a on the element 1a of the collimator. The clear glass plate 10 is fixed to the element 1 of the oollimator. The lever 9 is controlled through a link 11 pivoted to it by a pin 19 at one end and to a lever 12 mounted on a support 14, by a pin 17 at its other end. One end, 12b, of the lever 12 moves over a graduated scale 12c on the support 14. Stops 15, 16 are provided on the support 14 to limit the motion of the lever 12. So that the device may be used for targets of different dimensions, the lever 9 has a number of coupling holes 18, in any of which the pin 19 may engage. The objective 5 is movable in its own plane in order to allow adjustment to be effected, by displacement of the line of sight.
