Title: Improvements in sheet collecting and stapling, stitching or other securing mechanism
IPC: B41F13/66
Filed: 1920-04-09
Abstract: 149,937. Hoe & Co., R., (Assignees of Sheldon, E. P.). Aug. 16, 1919, [Convention date] Associating-apparatus; cutting-apparatus; stapling, stitching, and like binding devices.-In apparatus for collecting sheets and stapling, stitching, or otherwise securing them together, particularly for use in printing-machines, the collecting and securing mechanisms are mounted on a common carrier and so arranged that either or both of these mechanisms may be rendered inoperative. A cutting-mechanism may also be mounted on the carrier for cutting the sheets from a web. As shown, sheet-cutting devices 41, coliecting-pins 5, and stapling-devices 18 are mounted on a common cylinder 1 co-acting with a cylinder 36. The pins 5 are normally retracted by springs 8 and are pushed outwards by studs 12 carried by arms 13 of a rock-shaft 14 and engaging with lost motion in slotted heads 11 of the pins. The shaft 14 is operated by a grooved cam 17, Fig. 2, loose on the shaft 2 of the cylinder 1. The cam 17 may be held stationary so as to operate the pins once during every revolution or may be rotated at half the speed of the cylinder 1 to operate the pins at alternate revolutions. For this purpose gears 47, 45, Fig. 2, mounted on an eccentric shaft 46 are adapted to be engaged with or disengaged from gears 48, 44 fixed to the shaft 2 and cam 17 respectively. When the gears are disengaged, the gear 44 is locked by a sliding latch 49. The stapling- devices each comprise a plunger 18, Figs. 3 and 10, which takes a length of wire cut off by a suitable mechanism and co-operates with a member 19 to form the legs of the staple. The plunger 18 is operated by an arm 30 fixed to a rock shaft 26 and is guided in slots 27 of a stapleinserting plate 22 operated bv a link 24 and arm 25 loose on the shaft 26. The shaft 26 is operated by a cam 34, Fig. 2, mounted and driven similarly to the cam 17, and the arm 25 is operated by a link 39 from an arm 37 on the shaft 14. The stapling mechanism may be rendered inoperative by removing the plungers 18 or stopping the wire feed and the collecting- mechanism may be made inoperative by removing the points of the pins 5.

Title: Improvements in or relating to apparatus for indicating resonance of mechanical vibrations
IPC: G01N29/06
Filed: 1949-04-13
Abstract: 664,077. Supersonic inspection systems; electrical indicating systems. SPERRY PRODUCTS, Inc. April 13, 1949. [April 17, 1948] No. 10011/49. Classes 40 (i) and 118 (ii). In a supersonic-inspection system, for measuring the thickness of, or locating the presence of a flaw within, a workpiece 10, wherein a continuous oscillation of cyclically varying frequency is generated at 15 and applied to the workpiece 10 to produce mechanical waves therein, resonance in the workpiece being indicated by a deflection of the beam of an oscilloscope 25, means are provided for producing a horizontal sweep of the cathode-ray beam from the oscillation so that the instantaneous deflection is at all times proportional to the wavelength of the waves in the workpiece. Since resonance occurs when the dimension to be measured equals a half wavelength, a linear scale of dimension is produced on the cathode-ray tube. The oscillatory output from the generator 15, which includes a continuously-driven variable condenser 16, is applied to amplifier 33 which includes an automatic-gain control circuit so that the output therefrom is of predetermined amplitude. This output is applied to a potentiometer arrangement comprising a resistor and condenser in series, the impedance of the resistor being much greater than that of the condenser. The signal across the condenser, which has an amplitude, proportional to wavelength is rectified at 40, amplified at 30 and thence applied to the horizontal-deflecting plates of the cathode-ray tube. In a modification, Fig. 2 (not shown) the resistor and condenser are replaced by an inductance and a resistor respectively.

Title: Process for dyeing polypropylene fibres
Filed: 1963-03-15
Abstract: Dyed stereoregular polypropylene fibres are produced by subjecting them, prior to dyeing, to treatment with an aqueous p  solution containing a reducing agent for vat dyestuffs effective in neutral or acid solution, contacting the so-treated fibres with an acidified aqueous dyebath containing a sulphuric acid ester of a lenco vat dyestuff and a reducing agent of said type, dyeing the fibres at the boiling point of the dyebath and subsequently subjecting the dyed fibres to oxidising conditions.  The preferred reducing agent is sodium formaldehyde sulphoxylate but zinc formaldehyde sulphoxylate and thiourea dioxide are also specified.  The fibres may be in the form of filaments, yarn, threads, cords or woven or knitted fabrics and they may be in the form of blends with cotton or viscose fibres. The pre-dyeing reducing bath preferably contains a non-ionic surfactant and may also contain soda ash.  The pre-dyeing treatment may be preceded by the usual scouring treatment.  The dyebaths may have a pH of 4-6 and contain sulphuric acid as well as a dispersing agent effective in acid solution preferably non-ionic, e.g. an alkylaryl polyether alcohol, but others are specified, e.g. alkylaryl sulphonates, higher alkyl benzene sulphonates, sulphonated naphthalene-formaldehyde condensates, isopropyl- and isobutyl-naphthalene sulphonates, N-oleyl-N-methyltaurine, higher alkyl esters of sulphosuccinic acid, sulphonated rosen or lignin sulphonate.  The final oxidation may be accomplished by air oxidation with or without the application of heat, an acid dichromate bath or a dilute sulphuric acid bath containing sodium nitrite.  The dyed fibres may be finished by soaping, rinsing and drying.  Examples of dyeing fabrics of polypropylene and its blends with cotton and viscose are given.

Patent GB-1059937-A (GB)
Title: Improvements in or relating to the manufacture of magnetic cores
IPC: H01F1/18
Filed: 1964-03-11
Abstract: A method of making a magnetic core comprises forming a stack of ferromagnetic laminae having a curable adhesive between successive laminae, subjecting the stack to pressure in a pressing device to reduce it to the desired size, and curing the adhesive, wherein the adhesive is thixotropic and cures to form a resilient synthetic resin, and asbestos, rubber &c. layers are interposed between the stack and the pressing device to avoid tangential stresses, or these are avoided by using in the pressing device plates of a material having the same coefficient of expansion as the laminae.  Abutments stop the press members when the stack has reached the desired size. The adhesive may be a mixture of one or more polyhydroxy compounds which are liquid at room temperature, and one or more crystallized polyisocyanates. The adhesive may be made thixotropic by brief heating, after application to the laminations, or by the addition of a filler, e.g. silica.  The crystallized polyisocyanate may be dimerized toluylene-2:4-diisocyanate or the crystallized reactive initial adducts consisting of di- or polyisocyanates and di- or polyhydroxy compounds, which act as polyisocyanates. The polyhydroxy compounds may be branched polypropylene-glycols and castor oil.  An accelerator for reducing the curing temperature may be organo tin compound.  In an example the adhesive consists of a mixture of castor oil, crystallized, pulverous, dimerized toluylene-2:4-diisocyanate, in the approximate ratio of 2:1, 3 to 7% of highly dispersed silica, and from 0.2 to 1% of water to adjust the level of thixotropy.  The adhesive is applied by rubber rolls and cured at 80 DEG  C. for about 30 hours.
