Abstract: ABSTRACT    This invention relates to a system such that when an electrically rewritable nonvolatile memory (24) is utilized in a heating appliance for cooking foods with heat, the protection of data, rewriting thereof and the collation of data readouts are carried out more positively and with accuracy.  A heating appliance employing such a nonvolatile memory (24) is provided with a protection circuit for preventing destruction of data in the memory (24) when the power source is turned on and off and a main control section (19) for periodic rewriting of memory data, whereby the data are protected against destruction and aging.  Moreover, when reading the data in memory (24), collation of data is carried out at least twice and when writing in data, the data so written is immediately read out and collated with RAM data in the main control section (19) for improved resistance to noise.

Title: Method of centering and fixing a light-conducting fibre in a light conductor terminal member, a light conductor terminal member produced by that method, and apparatus for carrying out the method

Abstract: A light conductor terminal member (1) in the form of a centering cylinder (4) comprises a hollow cylindrical outer portion (10) of relatively hard material, and a core portion (11) of relatively soft material. The core portion (11) has an axial bore (5) for accomodating the end (2) of the fibre. The fibre end (2) is secured concentrically to the outside surface (14) of the centering cylinder (4), by means of upsetting of material (12). The material upsetting effect is produced by an annular upsetting tool (8) which is moved by means of a punch member (7) in a guide sleeve (6) which can be fitted over the outside surface (14) of the centering cylinder. That centering process permits a relatively large clearance between the axial bore (5) and the fibre end (2). Fixing and centering are effected directly in the plane of the end (9) which at the same time is the coupling plane.

Abstract: Abstract of the Disclosure An articulated manipulator and control are provided for producing controlled motion of a function element carried by the manipulator.  The motion is defined by input signals specifying with respect to a rectangular coordinate system the positions and path velocities therebetween of a tool centerpoint associated with the function element.  The control interpolates intermediate points along a predetermined path between any two positions.  The intermediate points are produced in accordance with a fixed period of interval and incremental velocity values instantaneously variable with each interval.          Continuous functions of acceleration and deceleration are produced to vary the velocity in accordance with the programmed description of motion.  Further velocity adjustment is permitted in accordance with unprogrammed variations of a preselected parameter.

Abstract: Abstract of the Disclosure Concrete strengthening members, particularly pre-stressing tendons such as strands of steel wire, are pro-vided with a strongly adherent plastic coating which may be substantially impermeable for improved corrosion resistance, and/or which may have embedded therein abrasive or grit-form particles to provide improved bond with the concrete, and particularly to provide controllable bond transfer in pre-stressing tendons of the pretensioned type.  The plastic coating preferably is applied electrostatically in powder form, and fusion bonded by heat.  The abrasive can be applied by spraying during a viscous state of the heated resin, and can be varied as to size and spacing density so as to control the surface condition and the bonding effect. Fusion and curing heat may come from preheating of the member before application of the resin powder, which pre-ferably is a heat curable, thermosetting epoxy.  Coating thickness and grit application are readily variable to meet particular requirements.  Particularly advantageous results are achievable for high strength steel strands for pre-stressing concrete by pretensioning, facilitating their use where previously considered impractical or impossible.

Abstract: ABSTRACT OF THE DISCLOSURE         An electrode comprising a substrate of a conducting metal, a coat of an electrode active substrate, and a layer interposed between the substrate and the coat to serve as a protective barrier for the substrate acquires improved durability by using, as the intermediate layer, a layer having platinum dispersed in a mixed oxide consisting of an oxide of at least one metal selected from the group consisting of titanium and tin, each having a valence of 4, and an oxide of tantalum having a valence of 5.  The electrode of improved durability is produced by a process which comprises the steps of preparing a substrate of a conducting metal, depositing at least one metal salt of Ti and/or Sn, and Pt from a solution on the substrate, heating the resultant coated substrate under the blanket of an oxidizing gas thereby forming an intermediate layer on the substrate, and subsequently coating the intermediate layer with a layer of an electrode active substance.

Abstract: LINE MOUNTED APPARATUS FOR MEASURING LINE POTENTIAL                ABSTRACT      A self contained hot stick mounted radio transmitting module may be permanently mounted on or temporarily pushed against the power conductor of electrical transmission line. The module is capable of measuring the potential difference between the conductor and ground. The module digitizes and transmits the value of the potential difference to a ground receiver.     The module is donut shaped and opens like a pair of jaws. The contact with the power line is accomplished via a resilient conductive elastomer that covers the surfaces in contact with the power conductor.     The potential difference between ground and the power conductor is measured with an operational amplifier in an integrating  configuration to  convert the  leakage  current from the module to ground into a proportional voltage from a low impedance  source.   The  integrator outputs  a voltage proportional  to  the  current  flowing  into  the  equivalent capacitance formed by the outer surface of the module and ground.  The current is generated by the voltage difference between the power conductor and ground.    The  power  conductor  is  engaged by  a  pair  of  jaws inserts comprising two concentric conducting rings separated by a thin insulating layer forming a large capacitor.     The electronic components within the unit are protected by a signal conditioning network to preclude destruction of components  in  the  event  of  lightning  strikes  or  other overvoltage conditions.
