Title: Improvements relating to electric circuit arrangements for indicating the occurrenceof fault or other abnormal conditions
Inventor: RALPH FRANK
IPC: H03F1/54
Filed: 1952-09-12
Abstract: 724,035. Protective arrangements. SIEMENS BROS. & CO., Ltd. Sept. 11, 1953 [Sept. 12, 1952], No. 22939/52. Class 38 (5) [Also in Group XL (c) ]. In equipment comprising a number of valves, warning of abnormally high or low current in any of the valves is given by connecting resistors RA in the individual cathode circuits, such that in normal working the D.C. voltages at test points TA are the same. Each test point TA is connected to a test line X via a varistor NA of the type in which resistance decreases with increase of applied voltage, irrespective of polarity. The test line X is connected to the grid of a valve XV, to the cathode of which a balancing bias is applied via resistors YJ, YK, YL, YM. The valve XV has the operating winding (I) of a relay in its anode circuit and derives its H.T. from an independent power supply UT. The relay is provided with a balancing winding (II) and the system is adjusted so that in normal working the relay contacts p1, p2 are open. Excessive cathode current in any of the valves decreases the bias on the valve XV, so increasing the current in the winding (I) and operating the relay, whereas excessive decrease in any cathode current causes the valve XV to be biased back and the relay is then operated by the balancing winding (II). A key switch K and auxiliary varistor KN are so connected to points in the resistor chain YK, YL, YM as to allow of simulation of either fault in testing. In another embodiment Fig. 2 (not shown) the test line is connected by way of varistors to resistors in the individual anode circuits to form a variable impedance network to which A.C. supply is applied via a fixed resistor. The voltage across the network is amplified and rectified to operate a relay with a balancing winding so that, as in the first embodiment operation occurs upon increase or decrease in any anode current.

Abstract: A cleaning solution for removing tarnish from metal surfaces consists of water, thio urea, or thio-phosphoric acid and a non-ionic surfactant. The surfactant is suitably a condensate of ethylene oxide with polypropylene oxide.  A powder composition consists of thio urea 30-85%, e.g. 65% meta-phosphoric acid 5-50%, e.g. 16%, surfactant 5-30%, e.g. 19%.  An aqueous solution comprises 3-9 (e.g. 6) parts by wt. powder composition dissolved in 100 parts by wt. water (see Division C7).ALSO:The surfaces of metal articles are treated to clean and remove tarnish by immersing said articles in a solution comprised of water, thio urea, or thio-phosphoric acid and a non-ionic surfactant; and cavitating said solution by the application of sonic energy.  The tarnish is formed of sulphide and oxide films and may be removed from the surface of silver, copper, and their alloys.  The cleaning composition may be prepared in dry form when it contains thio urea, meta-phosphoric acid and a melting agent, which composition is dissolved in water preferably with heat applied and advantageously with sonic energy applied <FORM:0957366/C3/1> The wetting agent may be a detergent having surface active and detergent properties, e.g. non-ionic surfactants such as Pluronics.  A mixed, uniform powder composition may consist of thio urea 30-85% (e.g. 65%), meta-phosphoric acid 5-50% (e.g. 16%), wetting agent 5-30% (e.g. 19%), Pluronic F-68 (for details see Specification). An aqueous solution comprises 3-9 (e.g. 6) parts by weight powder composition dissolved in 100 parts by weight water, and the action of this cleaning composition may be enhanced by mechanical agitation as provided by ultrasonic cavitation of the cleaning solution from sonic energy at a frequency and power amplitude sufficient to produce cavitation. The frequency is maintained above 10 kilocycles per second with a practical limit of 120 kilocycles per second, normally being at 20 kilocycles per second; and the power input advantageously may be 80 watts per gallon of aqueous solution. The solution may be cavitated by subjection to sonic energy for 1/2 -5 minutes, e.g. 1 minute, and cleaning is performed in sonic cleaning apparatus.

IPC: C02F5/08
Filed: 1957-07-23
Abstract: Aqueous media containing iron and/or ingredients which cause hardness of water are treated to sequester the iron, and to reduce or prevent the formation of precipitates and discolourations during the use of the media (e.g. in the mercerization, bleaching, washing, dyeing or after-treatment of textiles), by adding triethanolamine and at least one condensed metal phosphate, and then adding alkali until the pH of the mixture is 10 or more.  The condensed phosphate may be a metaphosphate, pyrophosphate or polyphosphate.  The use of an alkali metal salt of gluconic acid in conjunction with the triethanolamine and the condensed metal phosphate is also mentioned.  Oxidizing agents (e.g. sodium periodate) or reducing agents may also be added to the aqueous medium.  In an example, triethanolamine and sodium tripolyphosphate are added to a dye bath prepared from hard water, Sirius light green BB and Glauber's salt, and the pH of the bath is then adjusted by the addition of soda.  In a further example, cotton fabric is washed with hard water (containing iron) to which has been added sodium dodecylbenzene sulphonate, triethanolamine and sodium tripolyphosphate, followed by sufficient soda to bring the pH of the bath to 10.ALSO:Aqueous media containing iron and/or ingredients which cause hardness of water are treated to sequester the iron, and to reduce or prevent the formation of precipitates and discolorations during the use of the media, by adding triethanolamine and at least one condensed metal phosphate, and then adding alkali until the pH of the mixture is 10 or more.
