Title: Improvements in apparatus for indicating the turning movements of craft, especially aircraft
IPC: G01C9/08
Filed: 1935-09-09
Abstract: 467,250. Indicating turning of aircraft &c. ZEISS, C., [Firm of]. Sept. 9, 1935, No. 25005. Void. Convention date, Sept. 10, 1934. [Class 97 (ii)] [Also in Group XIX] In apparatus for indicating turning movements of craft, especially aircraft, a mass having an elastic restraining force and being insensitive to gravity and centrifugal influences can oscillate about an axis rotated by driving mechanism about an axis at right-angles to the first axis so that turning movements of the craft give rise to Coriolis forces causing turning moments on and oscillations of, the mass about the first axis. The amplitude of the oscillations of the mass about the first axis are, if undamped, proportional to the angle of turn of a craft and, if damped, to the angular velocity of turn. In the form shown, the axle a of an aluminium disc m is pivoted in a fork on the shaft b and is restrained by a spring t. The shaft b is driven by clockwork mechanism, electromotor, &c. w at a frequency equal to the frequency of oscillation of the disc m. Eddy current damping may be provided by a magnet d. The oscillations of the disc m are determined by observing the motion of a marked point p on the periphery with references to crossed lines on a screen k. When the craft is pursuing a straight course the point p is stationary and coincides with the intersection o. When the craft turns, the point p describes on the screen k a circle passing through o, the direction of the craft's turning vector, see arrows in Fig. 3, being indicated by the tangent to the circle at o and the magnitude of the turning by the diameter of the circle. In a modification light from a lamp fixed to the shaft b may be transmitted by a reflector and lens fixed to the fork to a reflector fixed to and oscillating with the axle a and from thence to an indicating screen. Alternatively the oscillations of the disc may induce electric currents or operate electric contacts whereby indications may be transmitted to a distance or the steering of the craft automatically controlled.

Abstract: 1,214,935. Fabric-film laminates. STAFLEX INTERNATIONAL Ltd. 22 May, 1969 [28 May, 1968], No. 25577/68. Heading B5N. [Also in Division B2] Fusible interlinings are produced by bonding together a woven or knitted fabric or a non- woven fabric having a defined pattern of apertures similar to the interstices of woven or knitted fabric, with a synthetic resin film which has a weight in the range of 5-50 grams/ square metre and softens at 100-200‹ C., and then subjecting the composite fabric/resin film material to heating and to a blast of gas from the direction of the uncoated surface of the fabric to rupture the areas of film covering the interstices or like apertures. The film which may have been stretched in one or two directions or may be unstretched may be formed of low, medium or high density polyethylene, copolymers based on ethylene, propylene, vinyl acetate or methylacrylate, polyamides or copolymers thereof or polyvinyl chlorides or copolymers thereof with or without a plasticizer and the fabric may be made from cotton, viscose rayon or nylon. In Fig. 1 base fabric 1 and heat softenable resin film 2 are drawn from supply reels 3 and 4 and are bonded together by passage between heated roll 6, which is preferably coated with a non-stick substance, e.g. p.t.f.e., and backing roll 5 which is preferably covered with hard rubber, the roll 6 being patterned if it is desired to bond the fabric and film over only selected areas. Alternatively molten resin may be extruded through slit orifice 7 and the resin film 8 bonded with the fabric 9 drawn from supply reel 10 by passage between cooled metal roll 11 which is preferably coated with a non-stick substance e.g. silicone rubber, and backing roll 12, preferably covered with hard rubber. The combined material 13 having the coated surface at the underside is then passed over preheating unit 14 equipped with gas burners or infrared radiators, beneath hot air blower 15 having a slit orifice extending for the full width of the combined material to disrupt the areas of film which cover the interstices in the fabric, and over a second hot air blower 16 or gas burners or infra-red radiators to melt the free edges of film material and compact the material and is then drawn by rolls 18 over cooling drum 17 and wound on to reel 19. Alternatively the fabric with the film on the outside may be carried in a tensioned condition around a perforated rotating drum, hot air being blown outwards through the perforations while infrared heating is applied from outside, a large proportion of the surface of the perforated drum being enclosed by a shield or screen. The hot air may be at 140-230‹ C. and may have a speed of 30/metres/sec. or higher. The interlining may subsequently be fused to another fabric, e.g. tweed, by heat and pressure. Alternatively the material may be bonded to another fabric directly after disintegration of the film by hot air blowing.

Abstract: 735,832. Optical gauging-apparatus. LEITZ GES., E. Sept. 16, 1953 [Sept. 22, 1952], No. 25615/53. Class 106 (2). An apparatus for measuring the distance between two surfaces of a bright body comprises a first optical projecting system 13, Fig. 1, and co-operating observing system 14 on the same side of and at equal acute angles a to the plane in which said surfaces will be presented, a second optical projecting system 18 and cooperating observing system 19 on the opposite side of said plane and at equal acute angles # thereto, the first and second optical projecting systems 13 and 18 forming coincident index marks in said plane, means 7 for causing said body to approach and pass said plane and means 10 for measuring such movement. The arrangement is such that as the body 4, Fig. 6a, approaches the plane, the reflected index mark from the projecting system 13 appears on a mark 261 to the left of two reference marks 34 in the observing system 14. If the angles α and # are equal the image 27<SP>1</SP> formed by the projecting system 18 appears, between the marks 34. As the body 4 is moved further to the left the mark 26<SP>1</SP> approaches the two reference marks 34 whilst the image 27<SP>1</SP> fades. When the surface of the body 4 is coincident with said plane, Fig. 6b, the mark 26<SP>1</SP> is between the marks 34. The reading on the scale 10 is then noted. Thereafter the body 4 is moved further to the left until its rear face is coincident with said plane, Fig. 4a, this condition being determined by observing through the second optical systems 18 and 19 the position of the body 4 for which the reference mark 261 produced by the second optical projector appears between the reference marks 34 in the second optical observing system 19. The reading on the scale 10 is again noted and the difference between said readings is a measure of the distance between the two surfaces of the body. The means for displacing the body 4 is a slide 3 operable by a knob 7. A magnifying device 40 may be used to view the reading on the scale. According to a modification only the projecting system 13 and the observing system 14 are provided, these being pivoted so as to be displaceable from the position shown to the positions of the optical systems 18 and 19.

Title: Leuco sulphuric acid esters of vat dyestuffs and their manufacture and use
IPC: C09B9/02
Filed: 1961-07-17
Abstract: The invention comprises leuco sulphuric acid esters of vat dyestuffs of the anthraquinone series which contain a reactive substituent, i.e. a substituent capable of entering into chemical combination with cellulose.  Reactive substituents described include chlorine or bromine atoms attached to triazine or pyrimidine rings, b -sulphato-ethyl and b -chlorethyl groups attached via aminosulphonyl, sulphone or amino groups, b  - chloropropionylamino, chloracetylamino, acryloylamino, chloracryloylamino and vinyl sulphone groups.  The dyes are made by condensing a leuco sulphuric acid ester of an anthraquinone vat dyestuff containing an amino group, or of an amino-anthraquinone which becomes a vat dyestuff on acylation, with an acylating agent containing a reactive substituent in addition to the acylating group. When the acylating agent contains a plurality of acylating groups the product may be further reacted with a mono- or diamine. Thus a leuco sulphuric acid ester of an amino-anthraquinone is reacted with chloropropionyl chloride, chloracetyl chloride, acryloyl chloride or chloracrylol chloride and di- or trihalotriazines and tetrachloropyrimidine are reacted with leuco sulphuric acid esters of mono- or diamino-anthraquinones (including aminodibenzanthrone) and in certain cases also with vattable or non-vattable amines of dyestuff or non-dyestuff character such as an amino substituted copper phthalocyanine sulphonic acid. The leucosulphuric acid ester of aminodibenzanthrone is made by reducing aminodibenzanthrone with zinc dust in the presence of the sulphur trioxide adduct of dimethylformamide in dimethylformamide containing methylamine and sodium b -naphthalene-sulphonate at 0-8 DEG  C.ALSO:Natural or regenerated cellulose textile materials are dyed and printed using lenco sulphuric acid esters of vat dyestuffs of the anthraguinone series which contain a substituent capable of entering into chemical combination with cellulose.  The dyes are applied by thermofixation, reductive pad-steaming, single-bath steaming, a cold-storage method, printing (by steaming), single-bath steaming without intermediate drying, an exhaustion method using a reducing agent, infra-red fixation, an exhaustion method without using a reducing agent and a printing method with infra-red treatment.  Details of these methods are given.  The esters also dye wool and polyamide fibres.
