Title: Improved method of and apparatus for forming fiber optical image transfer devices
Inventor: COLE HENRY BOGARDUS
IPC: C03B37/15
Filed: 1965-07-23
Abstract: A method of fusing light-conducting optical fibres together comprises the steps of holding the fibres together in side-by-side relation to form a bundle, heating the fibres to a fusing and softening temperature only adjacent a plane extending transversely of the fibres at one end of the bundle and axially compressing the fibres to bulge them into fused relation to each other only at said one end, heating the fibres to said fusing and softening temperature only adjacent a plane extending transversely of the fibres at the opposite end of the bundle, and the fibres are then axially compressed for further bulging the fibres into fused relation only at said opposite end of the bundle.  A plurality of glass fibres are placed in a bundle within a non-wetting refractory sleeve 16 (Fig. 1, not shown), and abut against a base portion 14.1. If desired, the fibre bundle may be wrapped in gold-leaf prior to fitting into the sleeve to facilitate removal therefrom after fusing.  A resistance coil 14.2 serves to heat the base and consequently the fibres.  A pressing plunger 22, also provided with electric heating means 22.2 is adapted to sealingly slide with the sleeve 16. At the initial heating stage oxygen may be introduced through a vent 24 in plunger 22 into the interstices between the fibres to burn off any matter therebetween. Thereafter a vacuum may be created to aid in the removal of any gases between fibres.  When the ends of the fibres only abutting the said end portion have reached the softening temperature (1150 DEG  F.) a pressure (of say 200 p.s.i.) is applied by the plunger, thus causing the fibres to bulge into contact and fuse with each other only at said end.  The ends of the fibres abutting the plunger are then heated to softening temperature and axially pressed to fuse together at that end.  In an alternative embodiment, Fig. 7 (not shown), the fibres may be placed in a bundle within a stainless steel sleeve 42 coated with a glass frit 44, the fibres extending axially outwardly above the sleeve 42.  Heating is then carried out as before a plunger 22 applying axial pressure both to the fibre bundle and the metal sleeve.  The fibres preferably have a flint glass core of m  = 1.62 and a cladding of crown glass of m  = 1.52.  The glass frit 44 would thus have the composition of the crown glass cladding.

Title: Method for the production of water and/or alkali soluble cellulose derivatives
IPC: C08B11/193
Filed: 1953-11-13
Abstract: In the manufacture of water- and/or alkali-soluble cellulose derivatives there is employed, as the source of cellulose, the "screenings" obtained as a waste product in the manufacture of chemical pulp from hard or soft woods by the sulphite or sulphate process.  The process is applicable to the manufacture of cellulose sulphate and cellulose ethers containing one or more of the substituent groups methyl, ethyl, hydroxyethyl, cyanoethyl, carboxymethyl and carboxyethyl.  The sulphate is prepared by the action of sulphuric acid on the raw material in the presence of organic solvents.  In examples, "screenings" are treated with caustic soda solution and the alkali cellulose so obtained is pressed, aged and heated with ethylene oxide and ethyl chloride in an autoclave to form ethyl hydroxyethyl cellulose.

Abstract: 384,064. Copying -telegraphy. HASSING, O. S., 51, Hellerupvej, Hellerup, Denmark. Nov. 19, 1931, No. 32099. Convention date, Jan. 16. [Class 40 (iii).] In a process for the manufacture of printing- blocks by purely mechanical working of a plane or cylindrical blank by means of a cutting- tool, in which the block is made from an original which is covered point after point by a spot of light whereby a light-sensitive cell is actuated to regulate, in accordance with the current impulses suitably amplified, the depth and hence width of cutting for a tool working the blank, point by point, such point on the blank being displaced in accordance with the spot of light on the original, the cutting-tool cuts the block intermittently at one point after another, the depth of each cut varying with the variations in the energy liberated by the cell and the shape of the tool is such that the depth of each cut determines the width thereof. The original 9 is mounted on a support 10 which is displaceable in two directions in its own plane so that the spot of light 8 from the source 6 can cover successively all points on the original, or, when the latter is flexible, it may be mounted on a cylindrical support which is rotatable and axially movable. The beam of light passes through holes 4 arranged on a rotatable plate 3 and is reflected to the light-sensitive cell 11. The current impulses generated are amplified and pass to an inductor such as the electromagnet 15, between the poles of which spring held armature 16 is disposed. A cutting tool 26 having a triangular end is mounted over the blank 27 which is supported by a member 28, moved correspondingly to the support 10, and the tool 26 is operated by an eccentric cam 20 mounted on the shaft 21 which is rotated once for every hole 4 on the plate 3 which comes between the light source 6 and the original 9. The depth of the cut is regulated by a wedge 19 carried by the armature 16, which is attracted to a varying degree by the electromagnet 15 thereby inserting the wedge to a greater or less extent between the eccentric 20 and the head of the cutting tool to regulate the depth and consequently the width of the cut. The cutting tool used may be a graver, drill, grinding stone, &c., and the wedge 19 may be replaced by a stepped wedge or helical or stepped surface acting by displacement or rotation. The original may be opaque or transparent, and reproductions may be made to scale. Alternatively, a block may be prepared directly from an object in space, or the cutting mechanism and amplifier may be combined with a wireless receiving device while the lightsensitive cell pick-up is combined with a transmitter for wireless transfer of pictures. By using monochromatic light or colour filters, blocks for colour printing may be prepared.

Abstract: 1,274,731. Strengthening glass. GLAVERBEL. 25 June, 1969 [12 Sept., 1968], No. 32149/69. Heading C1M. A body of glass, vitrocrystalline material or ceramic is chemically tempered as by ion exchange to provide a surface under compressive stress, after which a surface stratum of the body, preferably 0À1-20 microns thick, is chemically removed. The stratum may be removed by use of a fluorine-containing medium, preferably of pH below 4, so that the optical properties are not impaired. The medium may be HF, possibly with H 2 SO 4  (e.g. a solution containing 6% by vol. of each), NH 4 HF 2 , or NaF+H 2 SO 4 . Alternatively, a hydroxyl-containing medium, e.g. NaOH solution, may be used. The treatment is preferably performed with the medium at 0-80‹ C. The body may be dipped in a liquid medium, or streams of the medium as gas or liquid may be led over the surface. Preferably the body is vibrated relative to the medium at sonic or ultra-sonic frequency. After removal of the surface stratum the glass may be treated with water or a basic medium (e.g. by placing in a humid atmosphere, or by immersing in, e.g. 20% NaOH solution at 30‹ C. Preferably the process is continuous, with the surface stratum being removed substantially immediately after the chemical tempering. The body may then be coated, as specified in co-pending Application 32148/69. The body, which may be a glass sheet, may itself form a coating on a substrate. Specification 1,274,732 is also referred to.

[Also in Group XL (c)] In a television receiver for negative modulated vision signals, the synchronizing pulses are separated by a self-biased transistor clipper, and noise pulses having an amplitude greater than the synchronizing pulses are separated by a second biased transistor clipper and applied in opposition to the first signal to reduce the effect of noise on the synchronizing pulses. The final I.F. amplifier 18 of the receiver is transformer coupled to the video detector 34, the first clipper 60 (which is self-biased by the R.C. network 68 so as to cut off between synchronizing pulses), and the second clipper 62 which is biased either by a battery 80 or Fig. 2 (not shown), the A.G.C. line of the receiver as to pass only noise pulses. The two transistors are of opposite polarity type and have a common supply 76 and common load resistor 77 in their collector/emitter circuits, hence the noise signals from clipper 62 oppose and cancel those passed by clipper 60.

Title: Improvements in or relating to lubricating grease compositions
Filed: 1959-09-22
Abstract: A lubricating grease composition comprises an oleoginous liquid vehicle and a minor proportion of a mixture of an oil-soluble magnesium or aluminium sulphonate and one or more basic compounds, the basic compounds being selected from the hydroxides and carbonates of magnesium and aluminium so that a cation different from that of the sulphonate is present.  The oleoginous liquid vehicle may be mineral lubricating oil, a vegetable oil (e.g. corn, cottonseed or castor oil), an animal oil (e.g. lard or sperm oil) or a synethetic oil (e.g. a polyalkylene glycol, a silicone or a high molecular weight ester, especially an aliphatic diester).  The sulphonate may be an alkyl, alkenyl, alkaryl, cycloalkyl or mahogany sulphonate or may be derived from substituted sulphonic acids such as diphenyl ether sulphonic acids, dicetyl thianthrene sulphonic acids, dilauryl beta-naphthol sulphonic acids, dicapryl nitronaphthalene sulphonic acids, hydroxy-substituted paraffin wax sulphonic acids, mono- and poly-chloro-substituted paraffin wax sulphonic acids, and nitroso paraffin wax sulphonic acids.  The lubricating grease may be prepared by (a) forming a first solution comprising an oil-soluble sulphonic acid, an oleoginous liquid vehicle and an aluminium alkoxide or a magnesium alkoxide-carbonate complex, (b) adding a second solution of an aluminium alkoxide or a magnesium alkoxide-carbonate complex, but which contains a metal different from that of the metal-containing compound of step (a), to the first solution, (c) adding water to the combined solution, (d) removing the solvents and (e) cooling and homogenizing the grease product.  The magnesium alkoxide-carbonate complex may be prepared by reacting magnesium with an excess of an alkanol containing less than 6 carbon atoms to form an alkanol-insoluble magnesium alkoxide and then passing carbon dioxide through the reaction mixture until a soluble complex is obtained.  In the examples, the oleoginous liquid vehicle is mineral oil or di-2-ethylhexyl azelate, the aluminium alkoxide is the isobutoxide or the isopropoxide, the magnesium alkoxide-carbonate complex is one prepared with the aid of methanol or isobutanol as the alkanol, and the sulphonic acid is a maghogany sulphonic acid or an alkyl benzene sulphonic acid.  In some examples, technical stearic acid or phenothiazine is added to the grease.
