Title: Improvements in and relating to sheet registering devices
IPC: B65H9/10
Filed: 1935-12-16
Abstract: 446,886. Feeding sheets. FABER & SCHLEICHER AKT.-GES., 8, Sedanstrasse, Offenbach-on-Main, Germany. Dec. 16, 1935, Nos. 34930 and 34931. Convention dates, Dec. 29, 1934 and April 6, 1935. [Class 100 (i)] Sheet-registering devices of the kind in which the sheets are registered against a front gauge 3 fitted with a covering plate 34 are provided with a suction nozzle 19 for engaging the front edge of the sheet 7 and ensuring its entrance beneath the cover plate 34. As shown in Fig. 1, the sheet 7 is covered by the preceding sheet 8 during the registration, and a preliminary separating device in the form of a hook 20 fitted with a cover plate 21 is movable with the suction device 19 in a slot 36 in the feed table 1 over which the sheet 7 is moved by tapes or bands. A slide 12 which is reciprocated by a cam 17, lever 14, and connecting rod 13 carries the nozzle 19, and the nozzle is moved at the same speed as the speed of the sheet when this reaches the position shown in Fig. 1 and the air pressure in the nozzle is reduced. As the nozzle moves forward the hook 20 is moved backwards by means of a connecting rod 2, lever 23, and a cam 25 formed on the guide 11 which guides the slide 12. The cover plate 21 is thus carried over the leading edge of the sheet, and the suction is then cut off and the slide moved slower than the tapes so that the leading edge of the sheet engages the vertical face of the hook 20 to effect preliminary registration of the sheet. The motion of slide 12 is then decelerated and as the leading edge is brought under the cover plate 34 the gauge 3 is depressed, and the cover plate 34 reaches its lowest position as the sheet touches the gauge 3. The guide 11 is then depressed about its pivot 27 by means of a cam 30 acting on a lever arm 28, and the hook 20 is moved clear of the sheet and the slide 12 and associated parts are moved back to the position shown in Fig. 1 by the time the cam 30 moves the guide 11 about its pivot to assume the position shown in Fig. 1. The preliminary registering devices may be dispensed with, or may form the only registering means. In a modification, Fig. 2, the nozzle 19 is raised about the level of the table 1 at the commencement of its operation to ensure engagement with the front edge of a sheet deflected. upwards. The gauge 3 and cover plate 34 are reciprocated in a vertical direction and also to and from the front edge of the table 1. In its return movement the nozzle 19 is depressed below the table level. In some cases only the cover plate 34 is moved, and this plate may have an oscillating motion instead of a reciprocating vertical motion. The invention may be applied to feeds other than overlapping stream feeds.

Title: Improvements in or relating to the manufacture of wetting agents for mercerising lyes
IPC: D06M13/322
Filed: 1936-12-21
Abstract: A reaction product of nitric acid with an unsaturated fatty acid, or a reduction product thereof is added to mercerizing lyes which already contain phenols and also wetting agents normally insoluble in the lyes such as hydrogenated aromatic compounds, alcohols, glycol-, polyglycol- and glycerine ethers, nitrogenous bases, naphthenic acids, sulphonamides, thiocarbamic acids, sulphamic acids and secondary aliphatic amines.  In an example, a nitration product of oleic acid, crude cresol and cyclohexanol are added to a mercerizing lye, and in another a nitration product of oleic acid which has been reduced with sulphurous acid, crude cresol and naphthenic acid are employed.  The use of di-isobutylsulphamic acid (see Specification 455,893) is mentioned as well as the nitration products of linoleic and ricinoleic acids.  The treatment with nitric acid appears to cause oxidation and decomposition of the fatty acids, together with the introduction of nitro groups.

Title: Improved combination of reticle and mask for producing interrupted beams of optical radiation
IPC: G01S3/787
Filed: 1960-10-13
Abstract: 898,205. Radiation choppers. BARNES ENGINEERING CO. Oct. 13, 1960 [Oct. 23, 1959; Dec. 28, 1959], No. 35109/60. Class 40(3). In a radiation "chopper" device comprising a rotatable disc 1 (Fig. 1) or a movable endless band 8 (Fig. 2 and 3) provided with one or more series of radiation interrupting bars alternating with radiation transmissive bars and co-operating with a mask 2 through apertures 6, 7 of which the radiation to be "chopped" is directed, the edges of the apertures (in the direction of motion of the bars) are provided with serrations of "saw-tooth" like shape and of depth equal to an integral number of cycles of the bar pattern. With this arrangement the average radiation (from a uniform source) transmitted through the "chopper" remains constant and when the device is employed in, e.g. an infra-red target detection system in which the radiation is "chopped" to provide an A.C. type signal (e.g. via a suitable detector 11, Fig. 2) for ease of amplification, only radiation from the target provides such a signal and general background radiation is therefore prevented from masking the masking target signal. The "teeth" on the edges of the mask may have a number of different depths governed by the relationship L = NC/Cos α where L is the (slant) depth of a "tooth"; α, the angle between the tooth edge and the direction of motion of the "chopping" bars; N, a positive integer and C the length of a cycle of the bar pattern. Fig. 4 shows the simplest case of a parallelogram according to this relationship which may be extended to forms such as shown in Figs. 5-7, the cycle length in each case consisting of one opaque and one clear bar. Different "teeth" may be of different lengths as shown in Fig. 8 provided that each "tooth" has a depth equal to an integral number of cycles of the bar pattern. The latter need not have an equal "mark-space" ratio (Fig. 9, not shown) and the cycle may consist of a number of bars of different (colour) transmission properties (Fig. 10, not shown), or as shown in Figs. 1 and 11, the pattern may comprise more than one cycle producing "chopping" at different frequencies. In the latter case the total aperture must contain an integral number of such patterns to prevent effective "chopping" of the background radiation so that the length of the aperture must remain constant. In the case of the embodiments employing single cycle patterns, however, the size of the aperture may be varied by varying the distance between the saw-tooth edges. This allows a large aperture to be employed for target detection and a smaller aperture for target tracking. If desired large apertures 6 and small apertures 7 may be provided in one mask as shown in Fig. 1. Instead of straight parallel lines the bar pattern may be formed as shown in Fig. 12, or as this figure rotated through 90 degrees, Fig. 13 (not shown). Additionally, the bar pattern may be inclined to the edges of the aperture as shown in Fig. 14.

Title: Process for the manufacture of pregnendiones
IPC: C07J5/00
Filed: 1936-12-30
Abstract: Pregnendiones are prepared from pregnendiols by the action of oxidizing-agents.  In cases where strong oxidizing-agents are used which would attack the nuclear double bond, it is necessary to protect the double bond by the addition of halogen or halogen hydride prior to the oxidation.  Suitable oxidizing-agents mentioned are chromium trioxide and also other compounds of hexavalent chromium such as chromyl chloride, and bichromates in acid solution, also alkali and alkaline earth permanganates.  The removal of the protecting halogen may be effected by zinc dust, by treatment with sodium iodide in acetone, and by careful treatment with hydrogen in the presence of catalysts such as platinum or nickel or basic agents. In this latter method care must be taken that no hydrogenation of the nuclear double bond occurs.  Removal of the protecting halogen hydride may be effected by treatment with pyridine bases, with alkali acetates in alcoholic solution or other alkaline agents.  The pregnendiones may be isolated by means of ketone reagents such as semicarbazide, thiosemi-carbazide, phenylhydrazine and substituted phenylhydrazines, such as p-bromo, nitro-, and diphenylhydrazine, hydroxylamine, benzylhydrazides, and quarternary ammonium acetohydrazides such as trimethyl-acetohydrazide ammonium chloride and acetohydrazide pyridinium chloride.  In an example, a glacial acetic acid solution of pregnendiol-3 : 20 is treated with bromine to protect the nuclear double bond, and allowed to stand at room temperature for 48 hours with chromium trioxide.  The bromine is removed by treatment with zinc dust and the product extracted with ether to yield the diketone pregnendione-3 : 20 which exhibits the properties of the corpus luteum hormone.

Filed: 1964-08-24
Abstract: 1,087,060. Optical apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug.24, 1965 [Dec. 17, 1964], No.36216/65. Heading G2J. An optical device complises a system of spherical mirrors 2, 4, 6 arranged to form on each other a plurality of images of an applied image by multiple reflections between the mirrors, together with detecting means responsive to at least some of the multiple images for providing representations of discrete portions of the applied image. The mirrors 2, 4, 6 are of equal radius of curvature R, the centres of mirrors 4, 6 lying on the surface of the mirror 2 while the centre of the mirror 2 lies between the mirrors 4, 6. Light from a laser 10 is projected on to a transparency 8 adjacent the mirror 2 so as to produce multiple images on the three mirrors. In order to represent the transparency 8 in separate portions a series of masks 24 are located between the mirrors 4, 6 and a series of photo-detectors 26. The mirrors 4, 6 transmit a small proportion of light incident thereon and this light is focused by lenses 20, 22 in the plane of the masks 24. A light pulse from the laser 10 will produce a series of output signals from the photo-detectors 26, the time delay between successive signals being 2R/C (C denotes the speed of light) and each signal representing a different portion of the transparency 8. In a modification, light passing through the masks 24 is focused by a futher lens on to a single photo-detector. In a second embodiment, the photo-detectors are located behind the mirror 2. Signals are transmitted to the photo-detectors through regions of the mirror 2 which have no reflective coating. These regions replace the masks 24 and are positioned to receive the relevant multiple images formed on the mirror 2.

Filed: 1974-08-16
Abstract: 1476987 Magnetic and electric separating AVCO CORP 16 Aug 1974 [16 Aug 1973] 36225/74 Heading B2J A method of separating a mixture of materials having substantially equal real or apparent densities comprises the steps of (a) combining an additional material with a selected material of the mixture so as to form a modified material having a different density; and (b) subjecting the mixture of materials, including the modified material, to a ferrofluid sink/float separation, in which the apparent density of the ferrofluid is modified by adjustment of a magnetic (see for example British Specification 1232871) or electric field, so as to separate the modified material, and hence the selected material, from the other material or materials of the mixture. The additional material may then be stripped from the selected material. The additional material which may be non-magnetisable, may be used to wet the surface of the selected material or to impregnate a porous selected material, e.g. mercury may be absorbed in the cells of a soft open-celled wood or foam. Particles of the additional material, which may be magnetisable, may be suspended in a wetting agent which wets a surface of the selected material, e.g. oil wets metals and water non- metals, e.g. ceramics. Two non-polar materials may be separated from each other by the interaction of a polar substance with one of the materials and subjecting the mixture to a ferro-electric fluid sink/float separation. The selected material, e.g. aluminium, may be reacted with an additional material, e.g. air, to form a third material. of greater density, e.g. alumina, or of less density. The reaction may be reversible for subsequent recovery of the selected material. The two materials may react to form a solution. The additional material which may be ductile may be mechanically interlocked with the material and be separated from a brittle material as in the process of separating aluminium from municipal wastes, including glass, which is described. Alternatively, the mixture may be compressed sufficiently to bond the additional material to the ductile material.
