Abstract: ABSTRACT      A material for acting as a catalyst for hy-drogen evolution in an electrolytic cell is formed from a host matrix including at least one transi-tion element which is structurally modified by incorporating one or more modifier elements at least one of which is a transition element to improve its catalytic properties   The utilization of a disordered material, which can be any of a number of different disordered structures, makes possible the modification of local order chemical environments of the material to create catalytical active sites for the hydrogen evolution reaction.          Modifier elements, including for example Ti, Mo, Sr, Si, La, Ce, O and Co, structurally modify the local chemical environments of the host matrix formed of a transition element such as Ni, Mo, or Co to provide a material having an increased den-sity of catalytically active sites which exhibits low overvoltages when utilized as a catalytic material for a electrolyte cell cathode.  The material may also include a leachable modifier element, such as Al or Zn, which is partially removed to further modify the material and enhance its catalytic activity.  The catalytic material can be formed by vacuum deposition techniques such as by cosputtering the host matrix and modifier elements to form a layer of catalytic material on an electrode substrate.

Granted: 1987-01-20
Abstract: ABSTRACT            The invention relates to a method and a device for the realisation of crystallisation of thermoplastic material of an article (13) or a preform (13) which is formed by a blank (10) and where the preform is preferably intended to be reshaped into a container.  In accordance with the invention the wall of the blank is provided with two later-ally displaced material regions (102,103).  A mechanical moulding device (20,21,22) reduces the material thickness in the material of the wall with commencement in the region thereof where the two mate-rial regions are laterally displaced relative to one another.     Lateral displacement of the material regions and reduction by the moulding device of the material thickness are selected in order to allow, respectively achieve a reduction in thickness equivalent to that the thermoplastic material obtains when it is stretched so that material flow occurs.  In one embodiment the lateral displacement is achieved by the moulding device.

Abstract: ABSTRACT       A security seal formed of a single piece of molded plastic and comprising an elongated strap having a socket at one end a stud at a medial portion, and a free end having an aperture to be received on the stud before the stud and socket are engaged.  The seal configuration provides a secure non-removable assembly and allows assembly with closure members having an aperture too small to allow the stud or socket to pass therethrough.  In one embodiment of the invention, the stud has a weakened portion at the base in a position such that if the weakened portion is cut or broken, it cannot be re-attached by fusing.  In another embodiment of the invention, the free end of the shackle  has two or more spaced apertures, any one of which may receive the stud when the stud and socket are assembled.  An aperture is provided in the shackle between the stud and socket to receive the end of the shackle, so that the size of the loop formed by the shackle may be adapted to the particular installation.  This aperture between the stud and socket also serves as a weakened portion to facilitate flexing of the shackle to allow engagement of the stud and socket, and is so positioned that on flexing, the stud and socket become aligned for engagement.

Abstract: TITLE A FREQUENCY COMPENSATING CURRENT CIRCUIT FOR    A CURRENT-COMPARATOR CAPACITANCE BRIDGE     INVENTOR  Eddy So ABSTRACT OF THE DISCLOSURE         A method and apparatus for rendering a high-voltage current-comparator capacitance bridge insensitive to frequency fluctuations when used for measuring inductance.  A compensating current, proportional to twice the change in the current through the reference capacitor due to frequency fluctuations, is driven into the first comparator winding through which the current from the reference capacitor passes, resulting in a current in that winding having frequency characteristics similar to those of the current passing through the second winding which is connect-ed to the inductance.  This compensating current 15 derived from a reduc-ed replica of the applied high-voltage by deriving a voltage signal which is a function of the frequency fluctuation, producing an amplitude con-trolled reduced replica voltage using the frequency fluctuation voltage and converting the amplitude controlled voltage to the compensating cur-rent for the first comparator winding.

Abstract: ABSTRACT OF THE DISCLOSURE    A sensor for a system that detects stresses and defects in a metal piece by employing the Barkhausen phenomenon enables static or dynamic testing of such metal pieces as hard steel in which only low levels of Barkhausen noise can be generated or which are configured in one of a large variety of shapes.  The sensor includes apparatus that ensures that a uniform time-varying magnetic field can be produced in all the metal pieces of a variety of shapes.  The sensor can include an energizing coil assembly which generates the magnetic field in the metal piece having a core constructed from such a material in which a low level of magnetic noise is generated as ferrite.  The level of the magnetic noise generated in the ferrite core is so low that, even if the magnetic noise is sensed by the sensing coil assembly, which receives the Barkhausen noise generated within the metal piece, that noise cannot interfere with the higher levels of Barkhausen noise generated in all ferromagnetic metals, including hard steel.          The dynamic sensor has apparatus, such as wheel assemblies, for maintaining an air-gap of a substantially constant depth between the specimen and the energizing and sensing cores. The dynamic sensor can also include an energizing core which can be reoriented relative to the sensor to determine the directional characteristics of stress and defects in the specimen.

Abstract: ABSTRACT          Into an opening (11) in the bottom part or wall part (2) of a smelting furnace (1) or of a casting ladle, a hollow cylindrical carrier element (7) is inserted which, for example, is releasably connected by means of screws with this bottom or wall part (2).  This carrier element (7) surrounds an outlet casing (6) made of refractory material in which a channel of passage (5) for the melt is provided.  At places facing each other with regard to the channel of passage (5), recesses (13, 14) are formed in the carrier element (7) in the manner of annular grooves.  In each of these recesses (13, 14), there is a coil (17, 19) which is protected from a direct contact with the outlet casing (6) by sections of wall (15, 16) forming the bottom of the recesses (13, 14).  One of the coils (17) may be connected with an AC current source for the production of a magnetic field, while the second, opposite coil (19) is connected to an evaluation circuit in which the signals induced in this second coil (19) are evaluated.  As a result of the attachment of the coils (17, 19) in a carrier element (7) separated from the wall or bottom part (2), the installation and dismantling of the coils (17, 19) has been simplified.  Moreover, the danger of damage to the coils (17, 19) does not exist in the case of a renewal of the outlet casing (6).

Abstract: Abstract of the Disclosure Fluid Operated System Fluid control systems frequently eliminate use of fluid operated jack protecting relief valves because additional visibility blocking and damage prone conduits are required to connect the relief valves to the reservoir.  A preferred embodiment of the fluid operated system has a controlling valve, a selecting valve, a fluid operated jack, a relief valve, a reservoir and a bypass valve is provided to controllably connect the relief valve to other portions of the system in response to the position of controlling valve and selecting valve.  Therefore, no additional conduits are required to connect the relief valve to the reservoir and thus the problems of reduced visibility, premature conduit leakage and conduit damage are eliminated.  The fluid control system is particularly suited for use in a work vehicle such as a lift truck having a lift mast.
