Title: Improvements in and relating to signalling by high frequency oscillations over line wires
IPC: H04B3/56
Filed: 1921-11-02
Abstract: 171,097. Huth Ges., Dr., E. F., and Schwarz, K. Nov. 2, 1920, [Convention date]. Wired wireless systems; duplex signalling. - Transmitting and receiving coupling wires, by means of which signals are simultaneously transmitted to and received from one or more line wires running adjacent and parallel to the coupling wires, are connected together through inductances or capacities and earthed at a common point in order that, while reception and transmission is not interfered with, damage to the instruments by lightning &c. is prevented. In the arrangement shown in Fig. 1, the transmitting and receiving coupling wires a, b, extending parallel to the conductor l, are connected over inductances s, t to a common point o earthed at e. The coils s, t are directly or indirectly coupled to the receiving and transmitting apparatus, as through the coil r, and the point o may be adjustable along them. Signal currents are cumulative in the coils s, t but static charges &c. pass to earth. Different frequencies are used for transmission and reception. Condensers may replace the inductances s, t and the coupling between the coupling wires and the receiving or transmitting apparatus made capacitative. The coupling wires are tuned by the adjustment of the inductances s, t (or the capacities replacing them) or by varying the frequency of the circuit r to which the wires a, b are coupled. If the two coupling wires a, b extend in opposite directions parallel to the wine l, currents of different phase will be induced in the wire l in the case of transmission, and in the receiving apparatus when receiving. In a modification, two coupling wires a, f, Fig. 6, are coupled by inductances s, t to transmitting and receiving circuits l, m respectively, a third wire n being connected to earth e through the inductances p, q. Transmitted waves pass over the branches a, n, but are prevented from reaching the branch f and the receiving circuit m by a rejector circuit w.. Received waves oppose one another in the inductances s, p, or the coupling between the coils s, p and the transmitting circuit l is made sufficiently loose to prevent received waves from influencing the transmitter. A condenser may be placed across the inductance q to form the rejector circuit. In another modification, the three coupling wires a, n, f are inductively coupled to the separate line wires of a three-phase supply system, the wire between the coils s, t, o being connected to a lightning-protection wire.

Title: Method for reducing corrosion in lubricating systems
IPC: C10G19/02
Filed: 1955-10-18
Abstract: Metal corrosion in Diesel engines in which fuel containing more than 1 per cent sulphur is used is reduced by adding to the oil flowing from the engine and containing acid products, an aqueous solution of an alkali metal phosphate having an alkaline reaction, in an amount sufficient to maintain the pH of the oil above 4, and separating the aqueous solution from the oil prior to its recirculation to the engine.  Application of the process to marine Diesel engines is particularly mentioned.  Phosphates referred to are Na3PO4, NaPO3, Na4P2O7, Na4P2O6, Na5P3O10, Na2HPO4, Na3HP2O7 and Na3HP2O6, and the corresponding potassium and lithium salts.  Lubricating oils mentioned are mineral oils such as oils refined by solvent extraction, solvent dewaxing, acid treating and clay treating and filtering, e.g. acid-treated distillates of 300-1000 S.S.U. viscosity at 100 DEG  F.  The separated used aqueous salt solution is removed from the oil and centrifuged, and purified oil recyled to the lubrication system.

Title: A Process for Spray-Crystallization of Sugar

Abstract: 1,191,908. Sugar agglomerates. NIPPON SHIRYO KOGYO CO Ltd. 27 June, 1967, No. 29688/67. Addition to 1,112,553. Headings A2B and A2E. [Also in Divisions B1 and C6] A method for the production of spherical grains of sugar involves spray drying a massecuite of fine crystalline sugar and a saturated solution of residual solute to form agglomerates of crystalline sugar containing from 2 to 5 per cent residual moisture, ageing the agglomerates to allow crystal growth to go to completion and drying the sugar crystals to remove residual free moisture. The massecuite may contain such additives as vitamins, drugs, synthetic sweetners, organic acids, condiments, flavourings and perfumes, food colours and plant extracts, exemplified by cacao, fat, vanillia and acetic, ascorbic, citric erythorbic, lactic, malic and succinic acids. One specific formulation consists of sucrose, concentrated apple juice, orange oil and yellow food colourant. According to an example, refined liquor of 85 degrees Brix was admixed with 5 per cent of massecuite as seeds in a crystalliser whilst cooling and with agitation. The massecuite obtained after some 3 to 6 hours had a viscosity of 5,000 cps. at 10‹C and was spray crystallised through an atomiser to give particles having a moisture content of 2-5 per cent. These were aged for 2-5 hours at 30-60‹ C. and after ageing, were dried to completion. In other examples, mixed solutions of 95 per cent sucrose - 5 per cent invert sugar and 90 per cent sucrose - 10 per cent glucose, respectively, were employed.

Class 39(ii) A dynamo lamp, of the kind embodying a generator driven by a compressed air turbine, is provided with a cut-out comprising a sealed chamber enclosing a movable contact member and having a flexible wall responsive to the internal pressure within the well glass or similar enclosure surrounding the lamp bulb, so that a reduction in the internal pressure due to the breaking or removal of the well glass produces movement of the cut-out to short circuit the generator. The turbine wheel and the rotor of the generator are mounted in a two-part casing 10, 11, compressed air being admitted through an aperture 12 in the lower part 11. The cutout is enclosed within an annular housing 30 which is held in an airtight manner against a packing disc 31 on the underside of the casing member 11 and has an inturned flange 32 at its lower end. A rubber diaphragm 35 clamped between the flanged end of the member 30 and a cover plate 36 supports, on its upper side, a metal disc 33 with a central stud 38 that bears upon the underside of a resilient contact blade 39 which is clamped at one end by screws 40 and co-operates with a fixed contact pin 41 adjacent to its other end. Normally the diaphragm 35 is distended upwardly by compressed air which is admitted to the interior of the well glass 16 and passes through one or more holes in the cut-out housing, so that the contact blade 39 is held away from contact 41 while the lamp is being supplied with current through contacts 45, 46; the edge of the metal disc 33 is then bearing against the annular flange 32. As soon as the internal pressure falls, due to any circumstances, the diaphragm 35 is relaxed and the contact blade 39 bears against contact pin 41 to short-circuit the generator.
