Abstract:
In a safety razor the blade is retained in a manner to permit limited movement relative to the handle in the direction of its longitudinal axis. This is accomplished with blade elements of the type comprising a blade mounted in a cartridge by retaining the blade cartridge in its receptor for movement relative to the receptor. In other embodiments, the receptor is mounted on the handle in a manner to permit limited movement of the handle in the direction of the longitudinal axis of the receptor. The latter embodiment may be employed with any safety razor having its handle positioned in angular relationship to the receptor. To enhance the relative sliding movement, a lubricant may be applied between the moving parts.
Abstract:
An electrostatic image of graphical information is formed on a surface, for example that of an endless tape, a drum or suitable paper, and then magnetic toner particles are applied to the surface and adhere thereto in correspondence with the electrostatic image. Portions of the same surface, in the case of the tape, or of another surface, when the drum or paper are employed, are magnetized, as determined by the location of the toner prticles, to form a magnetic image corresponding to the electrostatic image. Then the toner medium are transferred by friction to a copy mdium such as ordinary paper, while the magnetic image is retained or stored on the surface. Toner particles then again can be applied to the magnetic image for production of additional copies. In other embodiments, magnetic material located on a surface in correspondence with graphical information, such as a hard copy comprising magnetic toner particles fixed to a paper substrate, is utilized in magnetizing a surface such as that of a drum or an endless tape, to form a magnetic image of the graphical information. The magnetic image can have toner particles applied thereto for photocopying by transfer to a copy medium such as paper, or it can be scanned to generate a sequential electrical signal indicative of the graphical information which signal is compatible with computer forms of storage and processing.
Abstract:
A method and apparatus are provided for electrolyzing water for enhanced production of oxygen, hydrogen and heat by the steps of (i) providing an electrochemical cell comprising an isotopic hydrogen storage cathode, an electrically conductive anode and an ionically conducting electrolyte comprising water, and (ii) impressing a repeating sequence of voltages across the cathode and anode comprised of at least two cell voltage regimes, a first cell voltage regime consisting of a voltage sufficient to enhance cathodic absorption of hydrogen, and a second cell voltage regime consisting of at least one voltage pulse which is at least two times the voltage of the first cell voltage regime for a total duration no greater than 0.10 seconds.
Abstract:
An electrochemical gas sensor cell is provided, the use of which permits quantitative measurement of volatile gas contaminants in an atmosphere being monitored. The cell comprises at least a first sensor electrode and a second counter electrode, on either side of an ion conductive electrolyte which may be immobilized in a matrix. The electrolyte may also be a solid electrolyte or a polymer electrolyte. The sensing electrode has a high surface area catalyst dispersed on a porous substrate, and is mounted in such a manner as to be exposed to the atmosphere which is to be sensed for gaseous contaminants, with the counter electrode being isolated from any exposure to that atmosphere. Generally, the electrodes are mounted in electrically conductive frames, sandwiching a third non-conductive frame member in which the ion conductive electrolyte is substantially located. The conductive frames may comprise electronically conductive materials such as conductive polymers, ceramics, nitrides, oxides and graphites. In an alternative embodiment, a further reference electrode may be mounted so as to be exposed to the electrolyte. The porous electrode may comprise a porous substrate or a base layer, a catalytically active metal, alloy, or metal oxide (usually a noble metal) dispersed in a high surface area form, carbon, and a polymeric hydrophobic binder.
Abstract:
An apparatus to continuously monitor a preset altitude for a pilot of an aircraft. It senses a change in altitude and an audible as well as a visible alarm tells the pilot that he has deviated from his preset altitude by a given height. Increase in altitude is signaled by a high pitch tone and by a yellow light while a decrease in altitude is signaled by a low pitch tone and a red light. The invention can also be used to warn a small boat operator of a pressure drop.

Abstract:
Abstract for filtering drinking water which includes a lower non-porous container to receive the filtrate. An upper filter vessel closed at its lower end by a high density ceramic filter is stacked in nested relationship to the lower container. When water containing contaminants and pollutants is poured into the filter vessel, it drips through the ceramic filter under gravitational forces and is stored in the lower receptacle.
Abstract:
An electrochemical gas sensor cell is provided, the use of which permits quantitative measurement of volatile gas contaminants in an atmosphere being monitored, generally at ambient temperatures below 100.degree.C. The cell comprises at least a first sensor electrode and a second counter electrode, on either side of an electrolyte which may be immobilized in a matrix, or a polymer electrolyte. The sensing electrode has a catalyst dispersed on a porous base, and is mounted in such a manner as to be exposed to the atmosphere which is to be sensed for gaseous contaminants, with the counter electrode being isolated from any exposure to that atmosphere. Generally, the electrodes are mounted in electrically conductive plastic frames, sandwiching a third non-conductive frame member in which the electrolyte is located. In an alternative embodiment, a further reference electrode may be mounted so as to be exposed to the electrolyte. The porous electrode may comprise a porous base layer, a catalytically active metal (usually a noble metal), carbon, and a polymeric hydrophobic binder.
