Filed: 1932-05-23
Abstract: 402,084. Transformers ; protective arrangements. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Ohio Brass Co. ; Mansfield, Ohio, U.S.A.) May 23, 1932, No. 14564. [Classes 38 (ii) and 38 (iv).] A series of transformers 10, 11, 12, Fig. 1 connected in chain or cascade and used for supplying instruments from a H.T. line 64 is protected by means of a condenser connected in parallel with the transformers and an impedance 15 connected in series with the supply to the transformers and condenser. The large current taken by the condenser on the occurrence of a surge causes a large potential drop in the impedance. The condenser is formed by shields 18-22 disposed adjacent the transformers and arranged to control the electrostatic field and grade the potential drop. The transformer covers 10<1>, 11<1>, 121 and shields may be connected to tappings on the windings to give a better distribution of potential. In a modification the shields are arranged alternately inside and outside the transformer housing 13. In a further modification Fig. 3 cascade connected current transformers 40, 41, 42 are mounted in the same housing as the potential transformers 43, 44, 45 and may be arranged on the same cores. To obtain phase angle correction in the potential transformer a compensating winding 49 connected between two condenser plates may be used. The Specification states that correction may also be obtained by connecting the cores 40, 41, 42 to tappings on the windings 43, 44, 45.

Title: A process for the manufacture of tartrates
IPC: C07C51/367
Filed: 1925-06-06
Abstract: Tartrates are obtained by halogenating fumaric or maleic acid after neutralization and heating the product in the presence of a carbonate or bicarbonate.  In an example, calcium carbonate is added to a suspension of fumaric acid and bromine is slowly run in.  On heating under a reflux condenser calcium tartrate is produced.  According to a second example, fumaric acid is neutralized with calcium carbonate and the cooled mass is treated with chlorine.  By adding a further quantity of calcium carbonate and boiling, calcium tartrate is obtained.  A metallic catalyst of the kind used for removing hydrogen halides, e.g. bronze, may be used in the final hydrolysis stage, which may be conducted in an autoclave under pressure of carbon dioxide.

Abstract: 963,115. Cooling liquids. DAIRY SUPPLY CO. Ltd. April 16, 1963 [April 17, 1962], No. 14938/62. Heading F4H. In an ice bank cooler, the thickness of the icebank is detected by a probe responsive to the change in electrical resistance when the water in the vicinity of the end of the probe is converted into ice. As shown, a milk cooler comprises a tank each wall of which comprises spaced outer, intermediate and inner walls, and refrigeration coils 24, 25 and 26 are located in the water containing space defined by the intermediate and inner walls. A probe comprising an electrode 9 extends through the outer and intermediate walls 21, 22 of the tank and into the water adjacent the refrigeration coil 24, a connector 1 being provided on the outer end of the electrode 9 for connecting the latter in an electronic control circuit (Fig. 3, not shown). The latter circuit includes a multivibrator, which supplies short pulses of electric current to the electrode 9, said pulses of current flowing from the electrode to the metal walls of the tank. The circuit is arranged so that only when the water in the vicinity of the electrode is frozen, i.e. the resistance to the current is large, are the pulses transmitted to a " flip-flop " circuit to trigger the latter into a state in which it deenergizes the refrigeration plant. Manual or thermostatic means are also provided for triggering the " flip-flop " circuit into a state in which the refrigeration plant is re-energized. If the walls of the tank are made of insulating material a metal plate is disposed in the water so that the current flows between it and the electrode, or alternatively two probes are provided and the current flows from one to the other. The probe may be movable so that the ice thickness may be varied or several probes extending for successively increasing distances into the water may be provided together with a selector switch for connecting any one of the probes into the control circuit. Instead of shutting-down the refrigeration plant the probe may give a visible or audible warning signal.

Filed: 1924-06-23
Abstract: 238,045. British Lighting & Ignition Co., Ltd., and Hutton, J. C. June 23, 1924. Dynamos, regulating; exciting.-To prevent batteries from being overcharged by dynamos having armature-reaction controlling-devices involving the use of a third or auxiliary brush, an alteration in the field windings between the main brushes is automatically effected to reduce the output of the dynamo upon the attainment of a predetermined voltage by the battery and the dynamo, and means are also provided for the restoration of the output of the dynamo to its full value when a load is switched on to the battery. In the arrangement shown, a field coil f<2> is normally connected between the main brushes but is adapted to be cut out by a switch a, bf which is operated by an electromagnet energized by a coil S' when the battery B is nearly fully charged. Before the connection of the coil f<2> is broken, a resistance R is connected in parallel with it to prevent high voltage from being induced. Instead of cutting out the winding f<2> an opposing winding may be cut in, or sections of the winding may be changed from a parallel to a series arrangement. When a lamp T or other load is switched on to the battery, a coil S<2> opposing the coil S<1> again closes the switch a, b to restore the output of the dynamo.
