Abstract: PURPOSE:To aim at reducing the consumption of fuel to save cost, by a attaching magnets to an automobile at several positions to utilize the action of magnetism in magnetic fields generated by the magnets and the action of static electricity. CONSTITUTION:Magnets such as permanent magnets of anisotropic type made of ferrite materials are bonded to an automobile at several positions to generate magnetic fields at the positions so that the fuel consumption of the automobile is reduced by use of magnetic force obtained by the magnetic fields and static electricity. For example, ferrite permanent magnets having 1,200 Gauss are attached each to the outer upper section of a fuel tank and the outer surface section of a container in a shaft section in a 50cc. motor-cycle. In this case, the motor-cycle provided with the magnets may travel 40.5km with one liter of fuel consumption which should be compared with a motor-cycle of the same type having no magnets that travels 30.5km with one liter of fuel consumption. It may be said that the mileage per fuel of the automobile attached with magnets is made to be longer.

Abstract: A polymeric composite structure having a configuration of a bathtub and a process of manufacturing the structure is disclosed. The polymeric composite structure includes an acrylic shell (12) and a plastic molded backing layer (14) which is bonded to a non-finish side (21) of the acrylic shell. A fiber reinforced resin layer, preferably fiberglass, is adhered to the non-finish side of the acrylic shell. A weight bearing reinforcing structure (16), such as chip-board, is adhered to the non-finish side of the shell (21) and to the fiber reinforced layer embedded within the molded polymeric backing layer. The molded polymeric backing layer (14) is made from a cross-linked thermosetting polymer, preferably a polyester blend, which does not contain isocyonate. The backing is bonded to the non-finish side of the shell and surrounds the fiber reinforcing and weight bearing reinforcing structures (16). The fiber reinforcing layer is bonded to the shell by a silane based coupler. The backing layer also includes a curing promoter, a peroxyde cross-linking promoter and a filler such as calcium carbonate, sand or other fillers. The composite structure is manufactured by a process which includes preforming an acrylic shell, reinforcing a non-finish side of the acrylic shell with a resinous mixture of reinforcing fibers by spray-up and roll-out techniques and arranging the reinforced shell in a mold with a non-finish side covering a reinforcing structure placed below the floor of the shell. An uncured mixture of the thermosetting polymeric backing and promoter is injected into the mold coating the non-finished side of the shell and covering reinforcing fibers and chip-board structure. The thermosetting backing material is cured sufficiently to permit demolding of the composite structure without damage. The shell is preferably primed with a silane based coupler prior to the reinforcing step. In an alternative manufacturing process, the spray-up reinforcing step is replaced by the placement of a fiberous mat within the mold, surrounding the non-finish side of the shell. The fiberous material may include a fiberglass woven or a mat material or it may include a preformed fiberous structure.

Title: Process for the absorption of carbonic acid from gaseous mixtures by alkali-carbonate solutions
IPC: C01B32/50
Filed: 1931-01-01
Abstract: In absorbing carbon dioxide from gaseous mixtures by means of ammonium or alkali carbonate solutions, either during the absorption process or between the individual stages thereof, sufficient time is allowed to permit the chemical combination of the carbon dioxide physically absorbed, whereby the best possible utilization of the lye is obtained.  The process may be carried out whilst circulating the lye in an absorption tower, the tower being in association with a container in which the chemical combination of the carbon dioxide takes place.  A small quantity of lye is continually added to the cycle, a corresponding quantity being continually withdrawn.  In another modification the process is carried out in an absorption tower provided with floors where the gas is brought into intimate contact with the lye.  The lye physically saturated with carbon dioxide passes from each floor through tanks placed adjacent to the column on its way to the next lower floor where it again comes into contact with the gases.  During the time the lye flows through the tanks the chemical combination of the carbon dioxide takes place further physical absorption then being possible.  The process can be advantageously carried out at temperatures between 40 and 70 DEG  C.

Title: Improvements in and relating to electrical wave filters
IPC: H03H7/01
Filed: 1935-01-02
Abstract: 447,213. Impedance networks. PADDLE, L. H., 92, Lancaster Road, West Norwood, London. Jan. 2, 1935, No. 133. [Class 40 (iii)] Relates to filters having a limb whose impedance is low for a frequency within the range handled by the filter and consists in employing in this limb an inductance for which the dissipation constant (R/2#fL) is greater than 0À01. In a M-derived filter, Fig. 1, the inductance L2 has the required ohmic resistance R added to the shunt. Since the ohmic resistance increases the attenuation in the pass range, when a plurality of sections are employed, each section is tuned to a progressively higher cut-off frequency to prevent the attenuation being cumulative. The added resistance may be inherent in the inductance.
