Title: Apparatus for the testing and measurement of visual power
IPC: A61B5/18
Filed: 1966-08-15
Abstract: 1,104,618. Sight testing apparatus. M. ISHIHARA. Aug.15, 1966 [Aug.24, 1965], No. 36448/66. Heading G2J. Apparatus is provided for testing pilots of high speed craft to determine their visual acuity and rapidity of identification of moving objects. To test visual acuity the pilot, spaced five metres from an annular wheel 7, Fig. 1, views marks 6 thereon through an aperture 2 and shutter 5, the latter being maintained open by rotating a handle 27, Fig. 2a so that the end of lever 37, which has an armature 3 thereon, is moved upwardly. The wheel 7 has a plurality of equispaced support frames for the marks 6 which are of similar shape and kind to those used in sight testing charts and are arranged in various series, each series being of a different size. The wheel 7 is rotated by hand giving a short time, such as 1-1À5 seconds, in which to read the marks, the series being changed until marks of suitable size have been provided. Then the handle 27 is moved to its original position, Fig. 2a, allowing the shutter 5 to remain closed unless electromagnetic coil 4 is energized and thus attracts the armature 3. The test for rapidity of identification is now undertaken by closing switch 34 causing motor 8 to rotate on insulating cylinder 9 carrying a series of conducting strips 10 of varying lengths connected by bus-bar 11 to a ring 12 and brush 13. On inserting a conductive plug 17 in one of a series of apertures 14 in plates 15, 16, the period of time in which shutter 5 is opened may be varied. To prevent flicker effects, the shutter 5 is actuated only once every five rotations of cylinder 9, by including in the circuit a contact 18 which is urged against a contact on a fixed bar 21 only when a lever 22 engages the cam strip 25 extending over a fifth of the circumference of a gear 26 rotated by a gear 24 at a fifth the speed of cylinder 9. The slots 14 are calibrated at 33 to give a measure of the fastest speed which can be recognised.

Abstract: In open-end spinning, piecing is made easier and failed attempts are reduced, in that, in piecing and in the elimination of thread breaks, during the piecing time (tA) the quotient of the thread rotational speed (1) and the thread draw-off speed (2) is increased in relation to the quotient of these two speeds maintained during the production time (tP). Preferably, during the piecing time (tA), the apparatus runs at a thread rotational speed reduced in relation to the production speed and at a thread draw-off speed correspondingly reduced superproportionally. <IMAGE>

Title: Rolling mill workpiece delivery thickness control
IPC: G05D13/00
Filed: 1970-07-30
Abstract: 1318096 Rolling mill control WESTING- HOUSE ELECTRIC CORP 30 July 1970 [25 Aug 1969] 36826/70 Heading B3M A rolling mill control comprises a programmed digital process control computer 34 with a model equation information supply to each mill stand to predict the screwdown position for each grade and gauge of workpiece and a correction factor supply to the computer to modify the equation in dependence on information received when a previous similar workpiece was rolled. The information received is stored in a memory while different workpieces are rolled and recalled when required. The information required to provide the correction factor is such as the delivery gauge and temperature, the entry temperature and gauge to each stand and the entry width. After the leading end has entered the stand, the stand is controlled conventially using load cells 32. The computer is supplied with information from a screwdown position detector 28, and a load cell 32 for each stand, an X-ray gauge measuring device 30 after the last stand, entry and exit speed measuring rollers 15 and a pyrometer 25. The model equation is deduced from the mill stand parameters etc. to predict the roll force for each gauge and grade of workpiece. Any constants in the equation are deduced experimentally. The store correction factors in the drum memory are initially all 1.0, Fig. 2 (not shown), and are modified, Fig. 3 (not shown), as similar workpieces are rolled. The changes of the correction factors are weighted in the core memory. A corresponding factor is recalled to the core memory when a certain gauge and grade of workpiece is being rolled and modified by the information supplied. After rolling the factor is stored in the drum memory. The computer receives information about the incoming workpiece from punch card or magnetic tape.

Abstract: 336,490. General Electric Co., Ltd., (Assignees of Patent-Treuhand-Ges. fiir Elektrische Gl³hlampen). July 13, 1929, [Convention date]. Metallic-vapour apparatus.- In a metallic-vapour luminous discharge tube, condensation of vapour in the electrode chambers is avoided by encircling the part of the tube remote from the electrodes with one or more metal rings provided with lamellae or ribs to ensure vigorous cooling. The vapour condenses on the cooled part of the tube encircled by the rings and is immediately vaporized again by the bombardment of ions and electrons. The filling may consist of the vapour of sodium, potassium, mercury, lithium, caesium or zinc, and for starting purposes a rare gas or a gas such as nitrogen may be added. As shown, a ring e mounted on the tube supports ribs g. Oxide electrodes may be used and may be heated by a filament.

Abstract: 320,814. Trent, W. E. Dec. 22, 1928. Coking and carbonizing processes.-Briquettes of coal duet bound with hydrocarbon oil are subjected to treatment in two stages, in the first of which they are heated in a limited atmosphere to drive off water and the more volatile constituents of the oil, and in the second stage, they are heated in an oxydizing atmosphere to coke the oil residuum. In a plant suitable for carrying out the treatment, the briquettes are placed in a retort 18. heated by gases from a furnace. 10. Air in limited quantity is admitted to the retort through a valve 36 and the vapours pass to a condenser 42 the distillates from which are recovered, while the uncondensed vapours are led by a pipe 46 to the combustion space of the furnace. The temperature of the retort is preferably maintained at 500-600‹ F., and the treatment is continued for from one to two hours depending upon the kind of coal used in the briquettes. To institute the second stage, the valve 36 is closed, a valve at 39 opened and a valve 44 swung over to cut off the condenser and allow air to pass to the retort from a heat interchanger 22 heated by the waste furnace gases, some of which may be returned to the furnace through a pipe 28. This air after passing over the material is utilized in the furnace by conducting it through a pipe 38 to the fire-grate. The temperature in the second stage may be higher than 600‹ F. provided that the fuel does not burn.

Title: Improvements in or relating to methods of producing sheets of wood veneer and the sheets of wood veneer so produced
Inventor: ALLAN MORRIS
IPC: B27L5/00
Filed: 1962-10-09
Abstract: 1,027,627. Woodworking. AARONSON BROS. Ltd. Oct. 8, 1963 [Oct. 9, 1962], No. 38253/62. Heading B5L. A method of producing a sheet of wood veneer comprises the steps of cutting a plurality of laminations, uniting the laminations using a adhesive to form a block having the grain of all the individual laminations running in parallel, the laminations being similarly bent to form a concavity running along a central portion of one surface of the block in the same direction as the grain of the laminations, and slicing the block with a knife which acts to cut successively across the layers of adhesive to produce sheets of figured veneer having smooth surfaces. The laminations 1 with adhesive, such as synthetic resin, therebetween are placed between the dies of a pressing apparatus, such as that described in Specification 1,107,823, and pressed to set the glue and form a block 6 with a U- or V- shaped concavity and the grain 5 and flower 4 running in the direction shown in Fig. 2. The block is then mounted in a jig 7 of a rotary peeling machine and a veneer 10 peeled from the block by a knife 9. With a veneer so produced, the artificial flower runs substantially parallel to the grain of the wood. Variations in the pattern of the veneer may be obtained by introducing small chippings between the laminations during the production of the block, and by using laminations of differing colours.
