Title: Reversible non-woven fibres with crimped fibre tufts
Inventor: CROSBY DAVID WINSTON
IPC: D04H11/08
Filed: 1965-02-13
Abstract: 1,135,641. Laminated fabric. ICI FIBRES Ltd. 21 Jan., 1966 [13 Feb., 1965], No. 6321/65. Heading B5N. [Also in Division D1] A method of making reversible non-woven fabrics comprises interposing a fibrous interlay 13 consisting of, or containing a substantial proportion of, fibres which possess a latent crimp between two bonded fibrous webs 11 and 16 to form a composite structure, subjecting the composite structure to a needle punching operation, wherein the needles enter from one surface of the composite structure and cause fibres of the fibrous interlay to become oriented through one of the bonded fibrous webs and to project beyond the surface thereof as fibrous tufts 27,and then to a further needle-punching operation wherein the needles enter from the opposite surface of the composite structure causing fibres in the fibrous interlay to become oriented through the other bonded fibrous web and to project beyond the surface thereof as fibrous tufts 30 and then subjecting the needle punched product to a treatment which develops the crimp latent in fibres constituting the fibre tufts and present in the fibrous interlay. The term "bonded fibrous web" is applied to an assembly of relatively loosely associated fibres which has been subjected to one or treatments e.g. by needling or adhesive union to bond together the fibres. The two bonded fibrous webs may be of the same or different compositions, the exemplified webs being a needled assemblage of heterofilaments of polyhexamethylene adipamide and a copolymer hexamethylene adipamide and #- caprolactam. The interlayer may comprise hetero-filaments of polyhexamethylene adipamide and poly #-caprolactam, of polyhexamethylene adipadmide and a copolymer of hexamethylene adipamide and #-caprolactam or heterofilaments formed from at least two of the following components: polyesteramides, polyesters, polyurethanes, polyolefins, polyacrylonitriles and polyvinylidenes, the components of the hetero filaments being arranged as sheath and core or in a side-by-side relationship. In a further embodiment, the fibres may comprise edge-crimped yarns e.g. of polyhexamethylene adipamide or polyethylene terephthalate which have been heated under tension to temporarily remove the crimp. Up to 50% of the fibres in the interlay may comprise non-crimpable fibres. Crimping may be effected by the application of heat or by a suitable chemical medium.

Title: Improvements in and relating to optical pyrometers
Inventor: SMART DESMOND
IPC: G01J5/00
Filed: 1962-02-19
Abstract: 1,018,472. Pyrometers. C. A. PARSONS & CO. Ltd. Jan. 24, 1963 [Feb. 19, 1962], No. 6372/62. Heading G1A. An optical pyrometer includes a device for determining the emissivity of a surface the temperature of which is to be measured, said device comprising means for directing a modulated beam of monochromatic light on to said surface and means for determining the intensities of the incident and reflected beams. After the brightness temperature Tb# of the surface A using light of of wavelength #, has been measured by known means using a "disappearing" filament 4 (Fig. 2 not shown) the apparatus is rearranged as shown in Fig. 3 in which light from the filament 4 is directed through an interference filter 3, and a beam chopper 7, and is collimated by a lens 1 so that the resultant beam is directed on to the surface A under investigation. A photo-transistor 6 is positioned in the path of the beam and pointed to receive radiation from the filament 4 in one position and is then turned through 180 degrees to receive radiation from the surface. The photo-transistor 6 is connected to a band pass filter tuned to the chopping frequency of the beam chopper so that the intensity of the modulated beam from the filament is thus measured before and after reflection by the surface A, and from these measurements and knowing the distance between the surface A and the phototransistor 6 which is measured by a rangefinder 8, the emissivity of the surface A can be determined and used to correct the brightness temperature previously obtained. In determing the emissivity it is necessary to know whether the surface A reflects specularly or diffusely and if diffusely in what manner. This is effected by comparing the intensity of the reflected radiation at various points along a radius r from a point on the surface by a further photo-transistor 6a. The pyrometer may use infra-red or ultra violet light. If the intensity of the incident beam is very much greater than that of the reflected beam it may be attenuated by calibrated filters or measured after attenuation by multiple reflection in filter 3. The invention may by applied to a total radiation pyrometer in which case the emissivity is measured at three wavelengths.

Abstract: 198,751. Barman, L. M., and Roneo, Ltd. March 4, 1922. Addressing and like machines.-In addressing or like printing-machines of the type in which stencil cards are positioned for printing between a segmental inking-roller and a segmental impression-roller, the rollers are adapted to be disengaged at the will of the operator to form a skipping device for cards not required to be used. Stencil cards B in a hopper A are fed forward between a segmental inking-roller E and a similarly formed impression-roller F by a reciprocating pusher D. The roller F is mounted on a spindle N carried by arms P pivotally mounted on a cross-bar Q, one arm being extended and terminating in a fork S within which works a cam T fixed on a spindle U provided with an external lever V. The cam T bears against an adjustable screw W such that when the lever V is in the position shown in Fig. 3, the roller F is pressed against the roller E, and when it is turned to that shown in Fig. 1, owing to a card being advanced for which no impression is required, the roller F drops by gravity out of engagement. A stop Z by contacting the screw W limits the rotation of the cam. The roller E is fixed on a shaft K, rotatable by means of a crank L, from which are driven by gears M, 0, X the roller F and also a crank and connecting rod for operating the pusher D. Inking of the roller E is effected from a supply J by rollers G.

Title: Improvements in ship logs
IPC: G01P3/46
Filed: 1954-03-05
Abstract: 758,755. Ships logs. WOLDSETH, S. March 5, 1954 [March 9, 1953] No. 6496/54 Class 40(1) [Also in Group XXIX] In a ships log of the type in which water flows through a housing containing a propeller 2 shoes 4 of magnetic non-corroding material, such as stainless steel, on the tip of each vane 3 of the propeller 2, move past the cast iron pole pieces 11 of pulse generator 7 housed in aside tube 5 of the flow duct and separated therefrom by non-magnetic plate 6 and the frequency of the resulting impulses is measured. The pole pieces, depending from the corners of a powerful permanent magnet 10, e.g. of Alnico and each carrying a coil 12 are arranged in two pairs each on a line parallel to the rotation axis. A shoe passing either pair reduces the reluctance of the magnetic circuit including the two pole pieces to produce a voltage pulse in the coils which is sharpened by making each pole piece narrow in the direction of rotation of the vanes. The circumferential spacing of the pairs of poles is half the distance between adjacent shoes to give two output pulses from the four series wired coils each time a shoe passes. The pulses are fed through low pass filter 18 to amplifier 13a and thence to limiter 13b, which produces an output of constant amplitude pulses which charge and discharge capacitor 22 through resistor 23, the appropriate limbs of a bridge rectifier 14 and moving coil meter 9, which is shunted by a calibrating resistor. The integrated current through meter 9 is therefore proportional to pulse frequency only and thus to speed. The limiter output may be directly measured by an A.C. meter. Instead of using magnetic shoes each vane or the whole propeller may be of magnetic material. The amplifier power supply is stabilized and regulated by neon tube 24 and resistor 16.

A method of making a thin walled tube by wall thinning of a tubular blank 11 comprises forcing a plug 13 through the blank whilst the blank is held in a close fitting containing vessel 5 resistant to internal pressure, the plug 13 being forced through the bore by the application of a primary hydraulic liquid under a pressure P1 on one side of the plug, a secondary hydraulic pressure P2 being applied on the other side of the plug. An apparatus for performing the method comprises the containing vessel 5 which is constructed of longitudinal segments having mating radial faces, a thin rubber outer sheath 9 and a pressure-tight cylinder 1 which is closed at its lower end by a plug 2 and at its upper end by a ram 15. The blank 11 has an end flange 12 which engages the end surface of the container 5 through an annular end plate 10. When the ram 15 is lowered the primary hydraulic liquid acts on the plug and on the outside of the container 5. Alternatively, the primary hydraulic fluid may act only on the plug and hydraulic liquid from a separate source is applied to the outer surface of the sheath 9. The method is described with reference to the production of a molybdenum tube 1À00 inch outside diameter and 0À906 inch bore from a blank of the same outside diameter and a bore of 0À125 inch. It is also stated that fins &c. may be formed on the outside of the tube.
