Abstract: "METHOD AND APPARATUS FOR FOLDING AN        ELONGATE STORAGE BAG"                      ABSTRACT OF THE DISCLOSURE         The apparatus comprises an assembly of three linearly positioned frames, namely a folding frame, a backing frame, and a  holding  frame.    Each  of  the  folding  and holding  frames comprises a circular array of spaced rods, which array can be advanced  and  retracted  longitudinally,  and  expanded  and contracted radially.   The backing frame comprises a circular array of spaced rods which are fixed.  The folding frame operates within the plastic storage bag to be folded.  The folding frame is adapted to expand to grip and stretch a length or "section" of the bag.  This section then can be advanced over the backing frame to bring it into register with the latter.  The frame can then be contracted to deposit the section of bag on the backing frame and the stack of bag sections already folded and carried thereon and to clamp the stack to the backing frame.  The folding frame can then be retracted to withdraw it from the stack.  The holding frame is adapted to be advanced over the backing frame, contracted to clamp the stack to the backing frame, and retracted to withdraw it from the frame.  The rods of the arrays are spaced so that the stack of folds may be clamped in a sawtooth fashion to hold them tight to the backing frame.  The holding frame rods, when clamped on the stack,  serve as a template for the next following section of the bag to be folded over.

Abstract: PROCESS  FOR  PURIFYING  AND  RECOVERING  CATALYST  SOLUTION         CONTAMINATED DURING THE  CARBONYLATION  OF METHYL  ACETATE          AND/OR DIMETHYLETHER     ABSTRACT OF THE DISCLOSURE      Catalyst solution contaminated during the carbonyla-tion of methyl acetate and/or dimethylether. To this end, the contaminated catalyst solution is subjected in a first processing stage to extraction with a dialkylether and al-kanol,  each of which has from 1-4 carbon atoms per alkyl group,  and thereby freed  from its organic contaminants, from acetic acid,  acetic anhydride and ethylidene diace-tate,  and the ether phase is separated from the purified promoter-containing  catalyst  solution;  next,  the  ether phase is treated in a second processing stage with iodine and/or methyl iodide;  the precipitated promotercontaining catalyst complex is separated and dissolved in the puri-fied  catalyst  solution  coming  from the first processing stage; the ether phase is separated into its constituents by distilling it;  recovered dialkylether and alkanol are used again in the extraction stage; fresh catalyst solu-tion is  prepared  from  the  recovered  mixture  of  acetic acid, acetic anhydride and ethylidene diacetate and from the united purified catalyst solution while residual di-alkylether and alkanol are distilled off, and the organic contaminants retained  in the residue of the ether phase distillation are expelled.

Title: Pre-insertion inductor arrangement
Inventor: O'LEARY RAYMOND P
IPC: H01H33/16
Filed: 1987-06-05
Granted: 1992-02-11
Abstract: ABSTRACT A pre-insertion inductor arrangement is provided for a circuit inter-rupting device or high voltage switch to reduce audible and electrical noise and to limit transient inrush current and/or voltages upon closing of the circuit by the circuit interrupting device or high voltage switch. The arrangement provides theinsertion of the inductor for a plurality of cycles of the source frequency and thus does not require precise timing. The pre-insertion inductor does not require the use of a stack of resistor blocks or cakes of the prior art. Further, since the pre-insertion inductor has relatively low losses, the energy dissipation requirements of the pre-insertion inductor are significantly less than for pre-insertion resistors. Additionally, since the pre-insertion inductor is not continuously in the circuit, there is no requirement to carry continuous load or fault current or to accomodate losses on a continuous basis. Thus, an effective inductance for the pre-insertion inductor can be achieved in a desirable configuration having compact dimensions. In a specific embodiment, the pre-insertion inductor arrangement inserts the inductance between a switch blade and a switch contact during the closing movement of the switch blade. A conducting arm arrangement extends radially from the switch blade and upon movement of the switch blade the conducting arm arrangement is moved into juxtaposition with a conductor connected to the pre-insertion inductor assembly. The pre-insertion inductor assembly is mounted on and to one side of the stationary switch contact. The pre-insertion inductor assembly is connected in series with the switch blade and limits the transient inrush current and/or voltages incident to the closing of the switch.

Abstract: ABSTRACT OF THE DISCLOSURE A viewing distance sensor for television receiver which can not have influence upon the remote control function over infra-red signals of other electronics equipments positioned in the periphery of television receiver and also can not be influenced by the infra-red signals transmitted from other electronic equipments. Since an infra-red signal is transmitted from the infra-red signal transmitter in the case of being determined a viewer to be positioned within the viewable distance from the front of television receiver, the false operation of other electronic equipments caused by the infra-red signal can be avoided. Also, since a control signal is not input to the screen controller of television in case the infra-red signals transmitted from other electronic equipments are received into the infra-red signal receiver in the television receiver, the false operation of the viewing distance sensor can be avoided.

Abstract: A system and method for analyzing molecular constituents of a composition sample includes:  forming a solution of the sample, separating the solution by capillary electrophoresis into an eluent of constituents longitudinally separated according to their relative electrophoretic mobilities, electrospraying the eluent to form a charged spray in which the molecular constituents have a temporal distribution; and detecting or collecting the separated constituents in accordance with the temporal distribution in the spray.  A first high-voltage (e.g., 5-100 KVDC) is applied to the solution.  The spray is charged by applying a second high voltage (e.g., +/- 2-8 KVDC) between the eluent at the capillary exit and a cathode spaced in front of the exit.  A complete electrical circuit is formed by a conductor which directly contacts the eluent at the capillary exit, or by conduction through a sheath electrode discharged in an annular sheath flow about the capillary exit.

Abstract: ABSTRACT OF THE DISCLOSURE     A microprocessor-based electronic timekeeping apparatus or stopwatch for measuring multiple intervals of time, such as the elapsed times of a race horse covering successive distances of a race course, is disclosed. This hand-holdable, self-contained stopwatch has four multiple-digit display fields for simultaneously displaying up to four measured intervals of time preferably in minutes, seconds, and fractions of a second. In a first mode of operation, the stopwatch is used to measure and display four overlapping intervals of time having a common starting time and different stopping times. In a second mode of operation, the stopwatch is used to measure multiple intervals of time which have an operator-determined untimed period between successive intervals. The stopwatch includes additional display fields for indicating the mode of operation and the specific intervals of time being displayed. It also includes internal memory so previously measured and displayed intervals of elapsed time can be stored and displayed later. Preferred methods of operating the stopwatch are also disclosed.
