Abstract: An arrangement for traffic analyzing for public telephone stations which are served from a telephone exchange. The exchange transmits charging pulses to the telephone stations through telephone subscriber's lines, when calls are requested from the telephone stations. A charging pulse counter is accessed through a charging pulse detector when a call is made. The counter counts the number of detected charging pulses during the observation period allocated to the calling telephone station. An analysis initializing circuit includes time recording data delivering means for periodically reading-out the charging pulse number in the counter and for resetting the counter after the observation period. A traffic analyzing circuit is connected selectively to charging pulse counters and compares the charging pulse number of each counter to at least two predetermined charging pulse number values specific to the telephone station at the end of each observation period allocated to the telephone station.

Abstract: An improved electromagnetic boiler water conditioning apparatus and method for energy saving, comprising an electromagnetic water treatment unit combined with an external sludge collector attached to the boiler for boiler bottom blowdown by means of a solenoid valve controlled by a conductivity probe within the boiler. The probe is electrically connected to the solenoid blowdown valve. The blowdown is initiated by the conductivity probe whenever the dissolved solids within the boiler as a result of evaporation become too high. The external sludge collector permits unimpeded removal of sludge formed in the boiler passing into the collector and is a straight pipe having a diameter of about 21/2 to 4 times, preferably 3 times, the diameter of the standard openings at the bottom of the boiler. The level of the water to the boiler is maintained by an automatic level control which can also be cleaned through the sludge collector.

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.

Abstract: An over the counter swab kit for self detection of gonorrhea in the male using an ampul containing 1% N, N, N' N' tetramethyl-p- phenylenediamene or tetramethyl chromogen. The method of taking a sample is also shown in which the open end of a tube is filled with a plug in the form of fibrous material. After a sample is taken of exudate from a male, the 1% solution of tetramethyl chromogen reacts with Neisseria gonorrhea which may be present in the exudate to produce a color change. The plug, before the test, is in a dry condition, the plug is activated only by the tetramethyl chromogen which is placed below the plug in the tube and the ampul broken to release its contents. A sufficient amount of 1% tetramethyl chromogen is held within the frangible ampul to wet the plug and this amount is 1/2 the volume than is used in the saline ampul in my companion patent application entitled Over the Counter Swab Kit for Self Detection of Gonorrhea in the Male Using Saline Ampul.

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.

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.

Abstract: A protective device protects low-voltage lines such as telephone lines of a cable. It is fitted to a cable connection head which comprises two junctions for connecting two conductive wires of each cable line to two conductive wires of a switching exchange. Each junction includes two separable leaf-spring contacts or a rigid contact. Each line is protected by an overvoltage protective circuit having a first terminal and a second terminal which is connected to ground referenced voltage. Conductive contacts secured to the body of said protective device connect the first terminal of the protective circuit to a contact junction of the head after the protective device is fitted to the head. The fitting of the protective device to the head does not require unwiring of the conductive wires with respect to the contact junctions of the head.

The main mechanical resonator is formed of an optical member such as a mirror and resilient means connected to the optical member and the vibration generator means impress upon the optical member through the resilient means a rotational or translational motion, the frequency of which is that of the main resonator. The auxiliary resonator is formed of resilient blades having a free end and another end connected to the frame and its resonance frequency of the auxiliary resonator is equal to the resonance frequency of the main resonator. The two resonators vibrate in phase opposition in order that the periodic mechanical stresses applied respectively by the two resonators to the frame have at any instant, one and the same direction and opposite senses.

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.

Abstract: An Apparatus arranged behind the blades of a plate shear used for cutting sheet metal strips from a sheet metal plate to remove these strips from a sheet metal plate to remove these strips from the place behind the blades of the plate shear and to stack these strips on piles at a predetermined position behind the plate shear.
