Patent GB-1081601-A (GB)
Title: Reflex reflecting sheets and articles
IPC: G02B5/128
Filed: 1964-08-05
Abstract: A reflex reflector comprises a monolayer of glass beads 11 of refractive index above 1.7 firmly partially embedded in at least one side of a layer of malleable and ductile metal 10 having a Knoop hardness less than the crushing stregth of the glass beads. The reflector is formed by <PICT:1081601/C1/1> <PICT:1081601/C1/2> pressing the beads into the metal under elevated temperature conditions.  The beads are held in position on a second metal layer 13 by a temporary organic bonding material 12, the layer 13 being advanced towards the layer 10 to effect the pressing operation.  The beaded surface produced is then washed free of the organic material 12.  The layer 13 has a Knoop hardness greater than that of the layer 10 but less than the crushing strength of the glass beads so that it "grips" the beads during the pressing operation.  The metal layer 10 is preferably aluminium but may be copper, lead, zinc, tin, gold, for example.  Such metals as lead are made specularly reflecting by deposition thereon of a layer of aluminium.  The soft metal layer 10 may be carried on an iron or steel sheet 14. Prior to the pressing operation a legend 15 of any desired shape may be coated on the reflecting face of the layer 10.  The glass beads 11 will then trap the legend in position.  In order to provide reflex reflection when the beads are exposed to either air or water, beads having a refractive index of 2.4 to 2.6 are mixed with beads having a refractive index of 1.8 to 2.0.  In a further embodiment the exposed portions of the beads are covered with a layer of elastomer which is then cured at 150 DEG  F.  Also the beads may be initially coated with a silicate veneer.

Title: Process of manufacturing artificial silk threads, films and the like from viscose
IPC: C08L1/24
Filed: 1929-10-21
Abstract: Cellulose xanthates, making filaments and films from.-In order to prevent the evolution of evil-smelling gases in the manufacture of artificial silk and films from viscose, nitrocellulose is dissolved in viscose already containing nitrous acid in the form of its salts. The nitrocellulose is decomposed into cellulose and sodium nitrite which with the nitrite already present oxidizes the sulphuretted hydrogen and diminishes the concentration of the carbon disulphide, sulphur dioxide and other sulphurous gases during the spinning process.  In an example 0,5 per cent of nitrocellulose containing 11 per cent of nitrogen is added to viscose containing about 0,4 per cent of sodium nitrite.  The addition of nitrocellulose is stated to increase the activity of the nitrite, and to reduce the ripening period.  In order to remove hydrazine which is formed in the spinning bath, it is preferable to add a small quantity of an iron salt such as ferrous sulphate to the bath.  A harmless complex iron salt is produced and is removed in the subsequent treatment.  The filaments are of a chocolate colour when first obtained, but resume the normal appearance after desulphurizing.

Abstract: 964,324. Automatic control of voltage and current WESTERN ELECTRIC CO. Inc. Sept. 22, 1960 [Sept. 29, 1959], No. 32599/60. Heading G3R. [Also in Divisions H2 and H3] The amount of energy supplied to a load 46 over a rectifier 58 from an A.C. source is controlled by a circuit 40 including a plurality of PNPN solid state switches the conduction of which is controlled by pulses formed in a circuit 48 connected to an error detecting circuit 52 so that either the load voltage or load current tends to remain constant. The pulse forming circuit, Fig. 1 comprises a monostable multivibrator including a pair of emitter-coupled transistors Q 1  and Q 2  connected to a transistor Q 3  which acts as a constant current means permitting linear relaxation of the multivibrator so that an error voltage V, representative of the variation, from a reference, of a voltage proportional to either the load current or load voltage, which is applied to terminals 10, 12, is transferred accurately into a function of time as a control pulse 14 at terminals 16, 18. The control pulse 14 is applied to a differentiating circuit 49 including capacitor 76 and resistor 78, Fig. 4, the resultant wave form being a train of sharplypeaked pulses 80, 81 constituting firing pulses which are applied over a gating network 50 to the PNPN switch 42 or 44 which fires to deliver a quantum of energy 94 or 96 to the load circuit. The area defined by the quanta of energy 94 and 96 is dependent upon the initiation times of the firing pulses 80, 81, these times being accurate functions of variations of the load voltage, or of a voltage proportional to load current, from a reference voltage. The error detecting circuit, Fig. 5 (not shown) includes a Zener diode as a reference source. The circuit may be modified so that the PNPN switches handle the full load current (Fig. 6, not shown).
