Abstract: ABSTRACT OF THE DISCLOSURE           A control system for sequentially communicating a source of pressurized fluid mixture to first and second beds of adsorption material to separate at least one component from the fluid mixture and produce a product fluid.  A pressure trans-ducer connected to a supply conduit develops a switching signal corresponding to a predetermined fluid pressure in the fluid mixture communicated to the first and second beds of adsorption material.  An electronic controller responds to the switching signal to sequentially develop first and second electrical sig-nals.  The electronic controller allows the first and second electrical signals to overlap for a predetermined controlled time period.  Valve electrical sequentially respond to the first and second electrical signals to prevent communication of the fluid mixture to one of the first and second chambers while allowing communication to the other of the first and second chambers.  A first branch of an outlet conduit connects the first bed of adsorption material to a storage chamber while a second branch of the outlet conduit connects the second bed of adsorption material to the storage chamber.  An equali-zer valve located in an intermediate conduit between the first and second branches of the outlet conduit, reacts to overlap of the first and second electrical signals to allow the fluid pressure in the first and second beds of adsorption material to equalize when the communication of fluid mixture to the first and second beds of adsorption material is interrupted to complete a cycle of operation.

Granted: 1981-04-28
Abstract: AUTOMATIC HIGH-SPEED WRAPPING MACHINE  ABSTRACT    An automatic high-speed wrapping machine for wrapping packages in heat sealable thermoplastic film is disclosed wherein¦ the film seal at the side and ends of the packages is made at a high rate of speed as the packages travel through the machine.          The packages travel continuously in a straight line through the machine and are delivered at the input end of the machine by a flighted infeed conveyor into a film inverting head where the packages are surrounded by the film, thence to the side sealing mechanism which forms a seal while severing the selvage from the packages, then into an end sealing mechanism where both ends of the packages are sealed and the film web connecting succeeding packages is severed.  The machine produces packages which have a sealed film wrap around the entire package which is then in con-dition for subsequent shrinking of the film if desired to pro-vide a package having a tight film overwrap.

Abstract: L'invention a trait à une cellule acousto-optique utile dans les dispositifs d'imagerie et d'holographie acoustiques. La cellule comporte une couche d'un cristal liquide qui possède des molécules réorientables sous l'action d'une onde ultrasonore.  Des parois stratifiées comportant chacune au moins deux couches transparentes à cette onde ultrasonore permettent un grand champ de variations de l'angle d'incidence de cette onde et contribuent à minimiser de façon substantielle les pertes acoustiques dans la cellule et à orienter les molécules du cristal liquide suivant un plan perpendiculaire à la direction de propagation de l'onde ultrasonore.  En outre, la structure de la cellule acousto-optique est elle à éliminer presque totalement les réflections multiples de l'onde sonore entre ses parois.

Abstract: Abstract Curable mixtures of polyepoxide compounds which contain an amine curing agent have longer curing times, find thus, in particular, good workability when used as adhesives, when N,N-dimethylethylenediamine derivatives or N,N-dimethyl-1,3-propylenediamine derivatives are used as the curing agents.      The mechanical properties are also frequently improved.

Abstract: Abstract A computer carrier strip having perforated feed is slit longitu-dinally and a label price tag strip having a gummed back is adhered to the computer strip, after which the strips are perforated to form tear lines, and cutouts are made to make a composite strip form carrying T-shaped label-price tag sheets connected together by perforated tear lines only at the tops and bottoms of the labels and with the price tag portions separated by the cutouts and connected to the labels only by perforated tear or fold lines superimposed along the slit along the computer strip.  A computer prints the names, addresses, contents of shipping cartons on the labels and prices on the price tags.  Then, when a carton having merchandise therein is to be shipped, the label for that carton is peeled from the backing strip and carries with it the price tag portion and the portion of the backing strip under the price tag portion.  The price tag portion, with its backing strip portion, is folded back under the central portion of the label leaving adhesive upper and lower portions which are pressed against the carton.  Then, when the carton reaches its destination and is opened, the user tears the label, with the price tags and backing strip portion from the carton, and removes the gummed price tags as needed.  Other com-puter strips have the label slit completely from each other, and in one of these computer strips, each label has one corner cut out to facilitate peeling the adjacent label.

The detector does not respond to a single extraneous or premature beat, but after a predetermined number of beats occurring above a predetermined normal beat rate the detector switches the pacemaker to an asynchronous mode.  Relative variation in the phase of the asynchronous pacing and the tachycardia beats results within a short time in occurrence of a pulse in the critical time period to stop the tachycardia., The use of sequential stimulation in both chambers overcomes some of the problems in selecting the proper site for stimulation.  Hysteresis is provided in the heartbeat rate detecting circuit for preventing premature discontinuance of the asynchronous mode due to masking of pulses by the refractory period of the QRS-wave amplifying circuits.

Title: Pretreatment of substrates prior to thin  film deposition
Inventor: JOHNSON RICHARD I

Filed: 1980-01-14
Granted: 1982-08-24
Abstract: ABSTRACT OF THE DISCLOSURE   To facilitate the ion bombardment of a substrate surface as a pretreatment step prior to depositing thin films in a high vacuum evaporation system, a thermionic electron source is placed in the cathode electrode used to generate the plasma that provides the ion bombardment. The thermionic electron source does not interfer with the basic function of the plasma system. Its main effect is to enhance the plasma efficiency by injecting electrons into the surrounding space, reducing charging effects on surfaces, neutralizing the plasma cloud, causing less plasma dispersion, and perhaps, most importantly, allowing the plasma to be sustained at lower pressures and higher voltages re-sulting in greater ion energies and mobility for improved surface bombardment. Other electron sources, such as, a cathode ray accelerator as a beta emitter, may be positioned to simultaneously or independently, to inject electrons into the plasma and to direct electrons toward the substrate surface to neutralize surface charge.
