Title: Method and apparatus for measuring the length of irregularities in the thickness of atextile yarn
IPC: B65H63/06
Filed: 1965-07-07
Abstract: 1,120, 981. Measuring the length of irregularities in thickness of yarn. W. REINERS. July 7, 1965 [July 9, 1964], No.28817/65. Headings G1A and G1N. A method of measuring the length of irregularities in thickness (slubs) in a textile yarn, involves making measurements capacitatively or photo-electrically, at a number portions of the yarn located adjacent one another in the direction of yarn movement, to produce values dependent on the dimensions of the yarn at those points, obtaining logarithms of these measurements and adding the logarithms together. The apparatus may comprise a set of photo-cells E 1 -E 4  (Fig. 3a) across which the yarn passes in front of a beam of light or (Fig. 3b) a set of separate capacitor plates C 1 -C 4 , arranged opposite a common plate C 5 , the yarn passing between the set and the common plate. In the photo-electric arrangement, for example, the output of each cell, representing the degree of illumination of the cell which depends on the dimensions of yarn or yarn slub interposed between it and the light, is fed to a circuit Fig. 5 or Fig. 6 (not shown) to transform the signal into a logarithmic one. The logarithmic signals from all four cells are combined in a summation circuit Fig. 9 (not shown) and the output of this is applied to a recording or monitoring device or to the input of a yarncutting device control circuit Fig. 11 (not shown) for an automatic yarn-cleaning apparatus. The combined logarithmic signal contains information as to the volume of a slub and as to its length (i.e. the number of photo-cells it overlaps) and is supplied to oppose a predetermined voltage representing the maximum allowable slub length or volume. If the logarithmic signal voltage exceeds the predetermined voltage, a transistor (16) is switched on and a yarn severing device activated. The predetermined voltage is set by means of three variable resistors determining yarn thickness, and the thickness and length of permissible irregularities. If the photodetectors are of the silicon type with an exponentially varying output, a special circuit is provided to convert this into a linear signal before the logarithmic conversion Fig. 8 (not shown). A circuit is also described for converting the combined logarithmic signal into an exponential signal which can be used to control yarn severing apparatus Fig. 10 (not shown).

Abstract: 322,044. Nagle, S. C. Oct. 9, 1928. Golf &c. practising appliances.-An apparatus for practising strokes at a ball resting on the ground is arranged to return the ball to approximately the same position after each stroke, and comprises an elastic ligature which is connected at one end to the ball and at the other by detachable means to the centre of a short transverse elastic member.

Filed: 1952-11-18
Abstract: 737,275. Electric control systems. WESTMINSTER FILMS, Ltd. Nov. 18, 1953 [Nov. 18, 1952], No. 29122/62. Class 40 (1). [Also in Group XL (b)] In a cine or television camera the amount of light passing through the shutter is automatically controlled by a photoelectric cell in accordance with light intensity. The invention is described with reference to controlling the opening of a conventional cine-camera shutter of the type in which a pair of constantly rotating semicircular plates 1, la are adjusted relatively to each other. The spacing of the two leaves is adjusted by a geared motor 8. In operation, deflection of the pointer of a photo-electric exposure meter 9 closes it with one of a pair of contacts 11, thus energizing the appropriate one of relays 16. Motor 8 is thereby energized and varies the shutter spacing at the same time repositioning through the screwed shaft 13 a block carrying the contacts 11, the adjustment ceasing when the pointer is positioned between the two contacts. An adjustable coupling 15 between screwed shaft 13 and motor 8 enables the block to be positioned initially. In the case of a television camera the motor may adjust an iris shutter. In the arrangement of Fig. 2 (not shown), the meter is clamped so that the pointer moves in a horizontal plane, the contacts 11 being arranged as shown in Fig. I so that the pointer moves between them. The Specification states that the photo-cell may control the relays by electronic means.

Abstract: 698,239. Sectional scraper conveyers. MINING ENGINEERING CO., Ltd. Nov. 2, 1950. [Nov. 14, 1949] No. 29145/49. Class 78 (i). A trapped scraper chain conveyer has upper pan sections composed of a plurality of longitudinal parallel pieces mounted above lower pan sections, and readily releasable locking members securing the upper to the lower pan sections and holding adjacent lower pan sections against longitudinal separation from one another. As shown each upper trough section consists of two pieces 2, 3 each of which carries a flange 4 to prevent the scraper chain 14 from jumping out of its working path. Thus the conveyer can be assembled by laying the scraper chain in the lower assembled trough, adding the pieces 2 and then coupling up the chain in the pieces 2, after which the pieces 3 are added. The lower sections have at one end tubes 7, Fig. 2, secured to the sections by cleats 6 and in assembling the lower trough these tubes pass through cleats 8 provided on the other ends of the sections thus holding the sections in alignment. Depending bars 10 carried by the pieces 2, 3 are received in vertical slots 9 cut in the tubes 6 and are locked in place by sliding locking bar 11, the large diameter portions 11b of which are adapted to engage and disengage grooves 12, Fig. 1, in the lower ends of the bars 10 on sliding from one extreme position to another. The bolt is shown in unlocked position with reduced diameter portions 11a opposite slots 9. Locking is effected by a blow from a hammer. The upper pieces are thus locked to the lower trough sections and the bars 10 in the slots 9 also lock together adjacent lower trough sections. Specification 698,263 is referred to.

Abstract: 248,115. V.L. Oil Processes, Ltd., Lucas, O. D., and Lomax, E. L. Dec. 9, 1924. Hydrocarbons, cracking.-In cracking hydrocarbons in the liquid phase by passing the oil into a cracking chamber C maintained at cracking temperature and under high pressure, the light products pass away through a reflux chamber D from which the heavy products are refluxed through a cooler E to the chamber C. The vapours pass through a valve d to an expansion chamber G, from which liquid passes through a cooler II to the fuel oil receivers J, and vapours pass through a dephlegmator F, a vapourrefining apparatus L, condenser M, and gas separator N to receivers O. The heavy liquid from the dephlegmator F is passed through a heat-exchanger K to the receivers J. Oil to be treated is drawn by a pump a<1> from a tank A and is forced either through the heatexchanger K and a pipe still B, heated either by oil from a tank R or by waste gases from the process from a gas holder P, into the cracking- chamber C or directly into this chamber through a pipe c. The cracking-chamber C is preferably lagged and not separately heated but may be heated by oil or gas burners, by electrical means or by super-heated steam. Oil from the base of the chamber C is passed by a pump c<4> to the inlet pipe b<1> of the tube furnace or through a valve c<5> to the inlet side of the pump a'. The upper, lighter layers of oil from the chamber C are passed by a pipe c<6> through a coil f in the base of the dephlegmator F, and thence into the expansion chamber G. The chamber C is maintained at a pressure of 600-1000 lbs. per sq. in. and at a temperature of 450-550‹ C. The chamber D is at the same pressure and is maintained at a lower temperature (200-400‹ C.), heating or cooling medium being passed through a jacket surrounding it if necessary. The expansion chamber G is maintained at about 75 lbs. pressure and 350‹ C. The Provisional Specification describes ,also that hydrogen or an inert gas such as nitrogen or carbon dioxide may be passed through the cracking chamber. Specifications 126,103 and 200,534 are referred to.
