  • Patent number: 4355113
    Abstract: An over the counter swab kit for self detection of gonorrhea in the male using saline ampul. A method wherein a pledget in the form of fibrous material is impregnated with a compound which reacts with Neisseria gonorrhea to produce a color change. The pledget, before the test, is in a dry condition and is activated by a wetting agent such as saline, when placed in contact with the pledget. The chemical compound used and incorporated into the pledget is selected from a group consisting of phenylenediamines. A sufficient amount of saline is held within a frangible ampul to wet the pledget and then to be drawn by capillary action through the swab on which a sample of exudate as a specimen is placed. The chemical compound is in the form of a mineral acid salt which dissolves in the saline and is transported by capillary action through the pledget into the swab. A purple color is created on the tip of the swab at the site of the bacteria and is a positive test for gonorrhea.

  • Patent number: 4317010
    Abstract: The remote monitoring system locates individually the pairs of intermediate amplification circuits in a remote location in the transmission line between a monitoring station and a monitored station in which circuit a fault diminishing amplification is to be located. The monitoring station transmits remote location signals and other control signals which can be mixed with the data signals normally transmitted over the line. The monitoring station analyzes any faults in the signals transmitted and looped in the line and also carries out remote-control of the gain variation of each amplification circuit without normal transmission of the data signals being interrupted. Signals transmitted from by the monitoring station over the forward channel of the line control four loops of the inputs and outputs of a remote located pair of amplification circuits and a gain regulating means inserted in the negative feedback loop, or inserted upstream or downstream of each amplification circuit in order to change its gain.

  • Patent number: 4310821
    Abstract: The printed inductance comprises at least a first conductive rectangular spiral having its geometric origin on the long midline of the rectangle and which is adapted to be folded at its midline while being supported by one of the faces of a flexible insulating supporting-plate. The supporting-plate is folded back through 180.degree. along the midline axis passing through the geometric origin of the spiral. The geometric origin of the rectangular spiral coincides with the internal connecting terminal of the conductive spiral, so as to produce a magnetic field which is coplanar with the plane of the folded supporting-plate. A second conductive spiral conforming in every respect to the first spiral may be supported by the other face of the supporting-plate. The first and second rectangular spirals are thus seen to be identical and symmetrical with respect to the fold axis. A hole having metallized walls connects the internal terminals of the spirals therebetween.

  • Patent number: 4300420
    Abstract: The apparatus comprises a sheet metal shears at a cutting station which station is provided with a lifting table 13 which is vertically adjustable, is used for cutting off small sections of sheet metal from a sheet and also is used for stacking these sections on a pallet 15. This lifting table extends through a cut-out side wall 5 for the shears and thus permits the shifting of an already piled-up stack 16 away from the shears, and then upwardly so that an adjacent stack 16a may be piled up neatly in spaced apart relation with stacks separated from each other by at least the thickness of the cut-out side wall. The continuing movement of the lifting table 13 after erecting the first stack 16 causes a small drop at the cut-off sections which are placed on the pallet 15, so that an orderly piled-up stack 16a develops. As the height of the stack increases the lifting table is gradually lowered until the predetermined height of the stack is reached.
