Title: Method and apparatus for recording and displaying measured values of individual samples from a random testing collection
IPC: G01D1/14
Filed: 1964-08-04
Abstract: 1,080,374. Magnetic recording-apparatus. L. ROHDE, and H. SCHWARZ, [trading as ROHDE & SCHWARZ]. Aug. 4, 1964 [Aug. 22, 1963], No. 31201/64. Heading G5R. [Also in Division G1] A method of recording and displaying measured values obtained on individual samples of a random collection of samples in which the measured values are stored successively in a desired sequence in one line on a record card 10 in such a manner that the geometrical separation of each individual recorded point from a pre-determined point of that line represents the corresponding measured value. A magnetic layer 11 may be stuck on the card, there may be several magnetic strips, the whole surface may be a magnetizable layer or the card may be made of magnetizable material. Slidable magnetic recording and reproducing heads 5, 6 or a combined recording and reproducing head are or is provided for marking the strip 11 and such marks may be supplemented with perforations made by a punch 45 carried by the slide 1. The displacement of the slide 1 corresponds to the analogue of the value and if several equal values occur, superimposition of the marks can be prevented by adding to each a displacement corresponding to the number of values already recorded. If the values to be recorded are not obtained in the form of analogue voltage values a known digital analogue converter may be used or an analogue reading on an indicating instrument can be converted into an analogue voltage using a manually operated potentiometer simulating the instrument and matching the readings by eye. A two co-ordinate plotter is used to produce a recorded display of the values recorded on the cards and reproduced therefrom. The display may represent (a) the statistical frequency variation of the values, (b) the cumulative frequency distribution or (c) the relationship between two measured values related to a chosen sample and stored on separate cards.

Patent GB-1150577-A (GB)
Title: Improvements in or relating to a method and Apparatus for Analysis of Surfaces of Structurally Heterogeneous Substances by an Electron Beam
IPC: G01N23/225
Filed: 1966-07-14
Abstract: 1,150,577. Microanalyzers. BÍHLER & CO. A.G. GEB. July 14, 1966 [July 14, 1965], No.31680/66. Headings G1A and G1N. An electron beam microanalyzer is used to investigate the distribution of phases in a sample e.g. an alloy. A particular phase is indicated by one or more elements, which are present to a larger extent in one phase than in another. The electron beam is controlled to scan the surface of the sample in straight lines at constant velocity. The electron current in the sample may be detected and the phase distribution determined by applying the output of the detector to a discriminator. Also X-rays and backscattered electrons are produced and either can be detected to produce voltage variations which are applied to the discriminator (4, Fig.4 not shown). This is set to pass only voltage signals in the height range corresponding to the indicating element, to control a transistor gate (5). Pulses of constant repetition rate from an oscillator (8) are thus passed to a counter only when the phase being investigated is present in the electron beam. The counter (6) is associated with a printer (7) recording the distribution. The proportion of the phase of interest in the surface area scanned is thus obtained by comparing the number of pulses passed by the gate and counted, with the number which would have been passed if the gate had been permanently open. Instead of using a single counter (6) electronic sorting means may be provided to direct pulse trains of different predetermined durations from the gate to separate counters where the number of pulse trains of particular durations are counted. The output of the gate may also be displayed on an oscillograph. Two or more elements, indicating a particular phase, are detected by respective detectordiscriminator channels, Fig. 5 (not shown), which connect to an AND or NAND gate (9), which precedes the oscillator Control gate (5). The applications include determination of phase distribution of ferritic-austenitic steels, using nickel as the indicating element for the ferrite and austenite phases, and of sulphide-containing steels.

Title: Process for spinning and doubling, in particular of artificial silk according to the can spinning process
IPC: D01D7/02
Filed: 1929-10-19
Abstract: In spinning and doubling artificial silk by the box or can method, a tube of flexible material such as paper, thin cardboard, or permeable textile material, is inserted in the box and is withdrawn with the spun cake which is thus in the form of a package suitable for transport to other machines or factories. The tube may be slit so as to accommodate itself to the box, and may be of such lineal dimensions greater than the height of the cake as to provide projecting parts for wrapping, such parts being, if desired, of star shape or of strip form.  The tube may subsequently be torn from the cake which can then be unwound from the outside.
Patent GB-606697-A (GB)
Title: Process for the production of resin-coated articles
IPC: B05D7/26
Filed: 1945-11-26
Abstract: Resin-coated articles are formed by coating the surfaces of solid articles with a composition comprising a monomeric unsaturated ester of a polycarboxylic acid, alone or with a partially polymerized unsaturated ester of a polycarboxylic acid, and particles of a solid polymer of an unsaturated ester of a polycarboxylic acid and solidifying the coating by applying heat to one or more solid surfaces in contact therewith.  Suitable esters are those in which at least two carboxyl groups are esterified with unsaturated alcohols, at least one of them being an allyl-type alcohol, preferably allyl alcohol.  Examples of polycarboxylic acids include saturated and unsaturated aliphatic acids, ethereal oxygen-containing acids, sulphonyl-containing acids and the preferred group of aromatic acids such as phthalic acid.  Other suitable esterifying alcohols include vinyl-type and propargyl-type alcohols.  The solid polymer may or may not be soluble in the liquid phase and the two phases may be admixed before, or simultaneously with, their application.  Catalysts such as peroxides, persulphates, perborates, peracetic and perphthalic acids may be added to the liquid phase.  The composition may also contain modifiers such as solvents, plasticisers fillers, pigments, lubricatns and dyes.  The compositions are particularly useful in the production of laminates (see Group VIII) made from fibrous material among which are included fibres of cellulose and its esters, nylons and interpolymers of vinyl halides with vinyl esters.  Improved hardness can be obtained by polymerizing in two stages, the first producing a gel at below 100 DEG  C., the second completing the polymerization at temperatures at least 20 DEG  C. higher than the highest temperature used in the first stage.

Title: Improvements in or relating to light projectors
IPC: F21W101/10
Filed: 1931-11-18
Abstract: 392,607. Adjusting light-projectors. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and WALDRAM, J. M., c/o General Electric Co., Wembley, Middlesex. Nov. 18, 1931, No. 31982. [Class 97 (i).] A device for adjusting light-projectors by ascertaining whether some object is in alignment with its own image and another object or image or whether one image of the object is in alignment with other objects or images, comprises a mirror or a combination of mirrors so shaped and so arranged in relation to the projector that a ray concerned in the formation of any of the said images will return along its own path after reflection at the said mirror or combination of mirrors if, and only if, it passes through the focus of the projector. The device may for example be used for adjusting the light source so that it lies accurately at the said focus. Fig. 1 shows the adjusting device for use with a deep paraboloidal reflector, i.e. one extending beyond the latus rectum of the parabola. The plane mirror 1 is mounted with its upper edge on the axis 3 of the reflector 2 and with its plane at right-angles to the said axis. An eye 4 on the axis sees its own image and the edge of the mirror 1 in line, and the source of light 5 is adjusted until the filament and its magnified image are in the same line, the source then being on the axis 3. If now the eye is placed at a point such as P away from the axis 3 it sees an image of itself formed by four reflections at the reflector 2 and a single reflection at the mirror 1, the line joining the eye to its image being parallel to the axis 3. The eye at P will in general see two images of the source 5, one above and one below its own image. The source 5 is adjusted until these two images coincide with each other and with the image of the eye, this adjustment bringing it to the focus 6 of the reflector. For use with a shallow reflector, Fig. 2, the adjustment device consists of a plane mirror 1 and a Mangin mirror 7, the latter being so situated that its focus coincides with that of the reflector 2 and the axes of the two reflectors are in line. To effect this adjustment of the mirror 7, a mirror strip 8, Fig. 3, is used which is placed above the axis 3 with its plane at right-angles to the said axis, and the mirror 7 is adjusted until the image of the observer's eye seen directly in the mirror 8 is in alignment with the image produced by the system 2, 1, 7 and remains aligned as the eye is moved towards or away from the axis. The combination of elements 1, 7 may be replaced by a plane mirror and a lens between the mirror and the focus 6, or by a single sphericallycurved mirror. A similar device may be used for adjusting a projector comprising a source of light and a lens.

Filed: 1928-11-03
Abstract: 327,423. Carpmael, A., (I. G. Farbeninindustrie Akt.-Ges.). Nov. 3, 1928. Cellulose esters and ethers, processes for making filaments from; apparatus for making filaments.-In the manufacture of artificial threads by dry spinning from solutions of esters or ethers of cellulose or its conversion products, the solution to be spun is preheated to a temperature higher than that at which the solvent or solvent mixture begins to boil at ordinary pressure, and is extruded into a chamber in which a current of air or other gas at a lower temperature passes in counter-current to the threads. Preferably, the solution is heated to the highest possible temperatune compatible with the production of continuous threads, and is extruded into a stream of air or other gas at ordinary or slightly raised temperature. Precautions should be taken to avoid radiation of heat from the nozzle into the surrunding atmosphere, which should be 20-50‹ C. lower in temperature than the solution. When working with a spinning atmosphere of very low temperature, a very long and narrow spinning chamber should be used. The air or other gas may be charged with a solvent preferably the same as that used in making the solution, and the solvent may include an aromatic hydrocarbon, particularly when spinning acidyl celluloses. Threads prepared as described above show advantageous properties in respect of strength, appearance, and resistance to boiling water. Examples are given describing the manufacture of threads under various conditions as set out above from solution of (1) cellulose acetate in acetone and ethyl alcohol, (2) cellulose acetate in acetone, benzene, and ethyl alcohol, (3) celluose acetate in acetone and benzene, (4) cellulose acetate in acetone and toluene, and (5) ethyl cellulose in methyl alcohol, toluene, and xylene.

Title: Improvements in or relating to the rectification of gas mixtures
IPC: F25J3/04
Filed: 1959-09-21
Abstract: 903,462. Cold separation of gas mixtures. LINDE'S EISMASCHINEN A.G. GES. FUR. Sept. 21, 1959 [Sept. 24, 1958], No. 32096/59. Class 8(2). In a two stage gas mixture e.g., air rectification process wherein a liquid component e.g., oxygen is withdrawn from the main column 6 through a duct 16 and is pressurized in a pump 17 before being revaporized in a heat exchanger 19 and discharged as product at ambient temperature through a duct 20, extra cold is provided by withdrawing vapour from the prerectification column 5 through a duct 21, passing it through coils 22 embedded in conventional nitrogen regenerators 2 for cooling incoming air, partially liquefying the so warmed vapour in the exchanger 19 is countercurrent to the pressurized liquid oxygen, separating the liquid in a chamber 24 and returning it through ducts 25, 3 to the column 5 and warming the vapour in an exchanger 68 before expanding in a turbine 29 and feeding to the column 6. As shown, warming in exchanger 68 is effected by nitrogen withdrawn from the head of column 5 through a duct 63 warmed in coils 64 within the regenerators 2, compressed at 65 to about 25 atmospheres and freed of its heat of compression in an exchanger 67; nitrogen leaving the exchanger 68 being mostly liquid and after being supercooled in an exchanger 69 is in part returned to the column 5 and in part passed through a duct 70 and a chamber 81 to serve as washing liquid in a column 71 for separating a mixture of hydrogen and nitrogen from admixture with carbon monoxide and methane. The crude gas is supplied to the column 71 through a duct 76 heat exchangers 73, 74, 79, 80 traversed by the counterblowing product mixture, the vessel 81 and a duct 82. Liquid carbon monoxide and methane is withdrawn from the sump 83 and after being vaporized in vessel 81 and exchangers 69, 66 is discharged through a duct 85. Cooling of crude gas by exchangers 73, 74 is assisted by a brine circuit 86 which includes a heat exchanger 87 in the oxygen discharge duct 20. In a modification heating of the vapour from separator 24 prior to expansion in turbine 29 is effected by a portion of the vapour withdrawn from duct 21 through a duct 32, Fig. 1 (not shown) and compressed to about 25 atmospheres.
