Title: Improvements in electrical switching apparatus for battery charging
IPC: H02J7/04
Filed: 1934-01-25
Abstract: 430,835. Charging batteries. ACCUMULATOREN - FABRIK AKT.-GES., 3, Askanischer Platz, Berlin. Jan. 25, 1934, No. 2617. Convention date, Jan 25, 1933. [Class 38 (iv)] [See also Group XXXVII] In an electromagnetic cut-out for use in battery-charging circuits the effect of separate differentially-acting series and shunt windings is obtained by a single winding and a network of resistances, a part of the charging current being arranged to flow through this winding and a series resistance which shunt a resistance in the charging circuit, a further resistance being arranged in series with the relay winding across the charging circuit. As shown in the Figure the effect of separate differentially-acting shunt and series coils is obtained by a single coil r and a network of resistances rl, r2 and w. These are connected in such a manner that a part il of the charging current i is shunted from a resistance w in the charging circuit over the whole or a part of the relay winding r and a variable resistance r2. A resistance r1 is connected in series with the relay winding r across the charging circuit. This resistance may however form part of the winding itself. The relay coil is thus energized in a manner, as described theoretically in the Specification, which is equivalent to that produced by differentially acting series and shunt relay windings and the resistances may be so chosen and adjusted that when a constant-voltage charging circuit is utilized and the charging current is at first relatively large the current through the relay coil is at first relatively small, but as charging progresses the latter current rises until the cut-off switch s is operated. The cut-out is particularly adapted to control an initial rapid charging operation and, if required, an additional slow charge may be given controlled by a timing device associated with the relay or by an ampere-hour meter.

Title: Process for the production of an aqueous dispersion of polyethylene or other thermoplastic polymer
IPC: C08J3/05
Filed: 1952-02-01
Abstract: Aqueous dispersions of thermoplastic polymers other than polychlorotrifluoroethylene from which steam-impermeable coatings and foils may be produced, are prepared by agitating the polymer in the form of a very fine powder with water and an organic water-miscible agent in which the polymer is insoluble, which does not react with the polymer and which can be removed by evaporation below 200 DEG C. The invention is exemplified mainly with polyethylene and also with polyvinyl chloride, polyacrylonitrile and polytetrafluoroethylene. Suitable organic water-miscible compounds are monohydric alcohols and aliphatic, carbocyclic or heterocyclic compounds of the following type: polyhydric alcohols, halogenated or aminated alcohols, ketones, acids and esters, ethers and amines, all having boiling points below 200 DEG C. p  Specified are ethanol, propylamine, diethyl ketone, tetrahydrofurane, gamma-chloro-propyl alcohol, ethyl acetate and ethylene glycol.  Fillers such as inert alumina gel or exfoliated mica, may be included in the dispersions.  On heating the dispersions to remove the water, a dry powder is obtained which is capable of being dispersed alone in water.  Specification 691,550 is referred to.

Title: Improvements in or relating to fault alarm arrangements for electric communication systems
Inventor: DALY CHARLES TREVOR
IPC: H04B17/40
Filed: 1952-02-04
Abstract: 700,149. Unattended repeaters. STANDARD TELEPHONES & CABLES, Ltd. Feb. 4, 1952, No. 2887/52. Class 40 (4). In a communication system having a number of unattended stations spaced along a route, a defective station is located over a circuit common to all the unattended stations by measuring the resistance of the circuit between the defective station, which terminates the circuit on the occurrence of a fault, and a second predetermined unattended station which is nearer to the attended station than the defective. station and can terminate the circuit in response to a signal from the attended station. This arrangement overcomes difficulties in station identification which arise when the resistance between stations is less than the resistance variation due to temperature of the total line. When the common line 6, Fig. 1 is earthed by a relay 19 at a defective station a fault alarm (not shown) at the attended station is operated by a relay 33 and the attendant operates key 29 to disconnect the alarm and couple the bridge measuring circuit. The first measurement indicates the location of the fault relative to the predetermined unattended station or " dividing " station, and switch arm 24 is set to the position corresponding to the section indicated. Line 6 is earthed at the appropriate " dividing station " by a key 36 at the attended station which operates relay 11 or 16 in accordance with the direction of the current through conductors 7, 8, and with resistance 23 at zero the. bridge is balanced by adjusting resistor 26. When key 36 is released the value of resistor 23 necessary to rebalance the bridge indicates which station past the " dividing station " is defective. The number of " dividing stations " should be large enough to keep the resistance variation between two of them less than the resistance between two ordinary unattended stations. Additional wires, e.g. interstice wires in a coaxial cable, may be used for terminating additional dividing stations or a different method of selectivity actuating the relays may be employed. In an alternative arrangement (Fig. 2, not shown) a pair of wires is used for the common circuit to avoid errors due to earth currents.

[Also in Groups XXXV and XL (b)] In a system for measuring the temperature of a body 10 radiant energy is directed thereto and the sum of the reflected and emitted radiant energy is measured. Radiation from a source 12 such as incandescent lamps or a spot-lamp energized through resistor 13 from battery 14 and mounted in a housing having an elongated opening 12a, is directed on to the areas 10c, 10d of body 10 having very different emissivities and resistor 13 varied until the radiation from each area as viewed through the unenergized optical pyrometer 11 is the same. The filament of pyrometer 11 is then energized and a reading of temperature taken in the normal way. Alternatively when the radiation from each area is identical a reading of meter 15 may be taken as a measure of the temperature. The surfaces 10c, 10d may be part of the body 10 or either or both may be added thereto. If body 10 is a bright metal strip, graphite may be added thereto. If body 10 is a bright metal strip, graphite may be added, or for an oxide work surface, platinum flakes may be used for the contrasting area. Alternatively in a ladle or furnace, slag or bubbles may provide emissivity contrast to the heated body.
