Filed: 1944-02-18
Abstract: 572,285. Supply meters. COMPANIA PARA LA FABRICACION DE CONTADORES Y MATERIAL INDUSTRIAL, and VITEAU, P. Feb. 18, 1944, No. 3066. [Class 37] In a direct-current ampere-hour meter comprising a permanent magnet disposed concentrically inside a soft iron cylinder and separated therefrom by a gap in which a movable element can turn around the magnet, and terminals for supplying current to the movable element, the magnet and the supply terminals are relatively displaceable in order to vary the motor couple for regulating the meter. In the mercury motor meter shown the permanent magnet 1 is in the form of a straight bar and has its magnetic circuit closed by a soft iron cylinder 2. Alternatively a cylinder magnetized transversely to its axis may be employed. In the gap between the poles of the magnet 1 and the cylinder 2 rotates a bell 3 of copper or other material of low resistance. The current to be measured is passed between terminals 4, 5 through the mercury and the bell. The magnet 1 is arranged to turn solid with a screw 6, so that it can be displaced relatively to the terminals 4, 5 for regulating the torque of the meter. The regulating device is also applicable to ampere-hour meters of the commutator type. Instead of displacing the magnet concentrically in relation to fixed current terminals, the two current terminals may be displaced concentrically in relation to a fixed magnet, or a single current terminal only may be displaced.

Title: Glass fibers
Inventor: LABINO DOMINICK
IPC: C03C13/00
Filed: 1957-01-30
Abstract: A fibre having a diameter of not greater than about 1 micron consists essentially of silica and an oxide of an alkaline earth metal.  The fibre may also contain from about 6 to about 18% chemically combined water.  The fibre is made by leaching the alkali from a fibre of alkali silicate glass by an aqueous solution of a watersoluble salt of the metal, the anion of the salt during the leaching forming a water-soluble salt with the metal of the alkali oxide, e.g. a sodium-silica fibre is leached with a calcium chloride solution to form a calcium-silica fibre. Small quantities of Al2O3 and Fe2O3 may be present.  A slurry of these fibres may be made and passed through a screen which retains a mat of the fibres which will function as a filter paper.  It is stated that a paper containing 1/3 by weight of these fibres mixed with 2/3 by weight of ordinary glass fibres will filter smoke from the air.  Specification 824,972 is referred to.
