Abstract: Abstract of the Disclosure The superconducting properties of superconducting compounds are controlled or maintained by active external electrochemical intervention.  The superconducting compound forms one electrode in an electrochemical cell.  A counterelectrode and the superconducting compound electrode are in contact with an electrolyte and a potential is applied between the counterelectrode and the superconducting electrode.  The cell is operated at a temperature near the expected transition temperature of the superconducting material.          The potential applied between the electrodes is selected to control a property such as transition temperature.          In a preferred embodiment, a superconducting material such as Ba2YCu307-x serves as an anode and a counterelectrode such as a mercury-mercuric oxide reference electrode serves as a cathode.  Suitable oxygen-bearing electrolytes are ozone and trifluoronitrosomethane.  In another embodiment, a superconducting cuprate material serves as a cathode and the electrolyte is copper-bearing.

Abstract: Abstract Weighted Relative System Response Elevator Car Assignment System With Variable Bonuses & Penalties An elevator control system employing a micro-processor-based group controller (Fig. 2) which communicates with the cars (3, 4) of the elevator system to determine conditions of the cars and responds to hall calls registered at a plurality of landings in the building serviced by the cars under control of the group controller, to provide assign-ments of the hall calls to the cars based on the summation for  each  car,  with  respect  to  each  call,  a  weighted summation of a plurality of system response factors, some indicative,  and some not, of conditions of the car irre-spective of the call to be assigned, assigning "bonuses" and "penalties" to them in the weighted summation.   In the invention,  rather  than  a  set  of  unvarying  bonuses  and penalties  being  assigned  based  on  the  relative  system response factors,  the assigned bonuses and penalties are varied based  on the  perceived  intensity  of  traffic,  as measured by, for example, a past average waiting time and the elapsed time since registration of the hall call,  a selected  past  five  minute  average  waiting  time  being exemplary.   Exemplary apparatus (Figs. 1 & 2) and a logic flow  diagram  (Fig.  3)  illustrate  a  specific  manner  of assigning calls to cars.  Tables set forth exemplary varying bonus and penalty values to be assigned, depending on the ratio of the hall call registration time to the selected average hall call waiting time (Tables 1 & 2) or on their differences (Table 3).

Abstract: "EASEL FOR PICTURE FRAMES"                   ABSTRACT OF THE DISCLOSURE         The easel is a flat, generally diamond-shaped member formed of non-scratching stiff,  resilient material,  such as plastic.  The member has a line of weakness extending thereacross between its  opposed oblique angle points.   The member  can therefore easily be bent along the line of weakness to adopt a two-sided  pyramidal  form  having  rearwardly  inclined,  load-supporting edges and bottom edges.  Means are provided along the load-supporting   edges   for   disengageably   supporting   and frictionally interlocking with a picture frame or flat sheet to be displayed in spaced, non-scratching arrangement above a flat support surface, such as a table top.  In the case of a channel-type picture frame, the means may comprise opposed L-shaped slots extending  inwardly  from  each  load-supporting  edge  a  short distance above the bottom edge.  The L-shaped slots form a T-shaped member.  The T-shaped member can frictionally interlock with the base channel of a picture frame, to suspend the frame in a rearwardly inclined display position.   Because each T-shaped member is formed at a point along its load-supporting edge, which point is spaced above the bottom edge, the picture frame is suspended above and out of contact with the table support surface.  In use, the side walls of the pyramidal member can  be  adjusted  together  or  apart  to  alter  the  angle  of inclination of the picture frame.   The frictional interlock between the T-shaped members and the channel ensures that the spacing of the side walls is maintained.

Date Apr. 28, 1983.Process for preparing aqueous dispersions of a somewhat water-soluble low-molecular organic material, in which swellable particles prepared in a first step are swelled with the organic material in the second step. When the organic material is a polymerizable monomer the dispersion prepared is converted to a polymer dispersion. In the first step swellable oligomer or oligomer-polymer particles are prepared by (a) dispersing an aqueous mixture containing an oil-soluble initiator or a solution of an oil soluble initiator in an organic solvent, and then swelling the dispersed initiator-containing droplets with monomer and effecting polymerization, or (b) swelling polymer particles in aqueous dispersion with vinyl monomer and an oil-soluble initiator and effecting polymerization, the ratio between initiator and monomer used being so high that in the polymerization an oligomer having a degree of polymerization of 5-200 is formed. In the second step, optionally after dilution with water and addition of emulsifier, the organic material is added which has a solubility in water of >10, preferably >100 times higher than that of the oligomer and which diffuses through the aqueous phase and swells the oligomer or oligomer-polymer particles in a ratio by volume of >20:1. When the organic material is a polymerizable monomer, initiator is also added in the second step, and polymerization is effected.

Abstract: This invention relates to an apparatus and a method for the production of outwardly ribbed, plastic pipes. The apparatus includes a core around which a plasticized material is pressed from a nozzle. A kernel having an essentially constant diameter is positioned at the terminal end of the core for a smooth inner face of the pipe. The outer face of the pipe is ribbed by grooves of axially displaceable chill moulds. The end zone of the kernel is provided for the cooling of the inner face of the pipe. In known apparatuses the grooves of the chill moulds are often filled incompletely and the inner face of the pipe becomes uneven on account of air bubbles, for instance. These disadvantages are avoided by heating an initial zone of the kernel for heating the inner face of the pipe and by shaping the surface of the initial zone to slightly expand conicallly in the production direction.

Abstract: A wide band, transistorized power transmitter for the execution of radio traffic requires a filter arrangement consisting of a large number of sub-filters because of the insufficient linearity of the transmitter end stage between the output of the transmitter end stage and the transmitter output. Depending upon the adjusted transmitter frequency, in order to suppress undesired harmonics, one of the sub-filters is switched into the signal path. The relays normally used to switch on and off the sub-filter are unsuitable for carryout out frequency jump operation. By effecting a suitable sub-division of the sub-filters of the filter arrangement into two and more sub-filter groups, between which it is possible to carry out a rapid and non-abrasive switch-over by way of electronic power switches, it is possible without too high an expense to carry out a frequency jump interval which can be arbitrarily adjusted within the overall frequency range.
