Abstract: Abstract of the Disclosure Method and apparatus for making diapers with elastic bands in the leg-contacting zone of the diaper involves forming folds, tucks or festoons in the diaper backing sheet or facing sheet and applying elastic ribbon treated with adhesive over the web and across the gaps of the folds so that the ribbon does not adhere to the web portion in the folds.  Hence the elastic ribbon is only adhered to the portions of the web between the folds.  The elastic ribbons are cut in the gaps of the folds, with the material in the folds later forming the non-elasticized waistband portion of the diapers.  At the ribbon-web assembly station, the facing or backing sheet is supported by spaced plates separated by gaps.  Before the ribbon is applied, the folds are formed by tucker bars which successively interfit in the gaps between the support plates and push the web into the gaps.

Abstract: ABSTRACT   A picture viewing device has a housing for accommodating a pile of pictures with the uppermost picture lying beneath a housing window.  A slider member may be pulled out of the housing and reinserted parallel to the viewing window.  A picture change mechanism consists of a transporter by means of which a picture can be removed from one side of the pile as the slider member is withdrawn and is guided to the other side of the pile again as the slider member is pushed in.  A retaining device prevents the remainder of the pile from being transported and an externally operable device disables the picture change mechanism for the removal of the entire pile out of the housing by means of the slider member.  The retaining device is in the form of a separator on the slider member and the transporter is in the form of retentive elements on an arrangement located in the housing under spring bias.  The pressure arrangement comprises a plate supported by springs the plate being of dimensions substantially corresponding to the size of the pictures, and on which the retentive elements are arranged.  The use of a pressure plate made of plastics material in conjunction with metal springs alloys inexpensive manufacture since the expensive spring materials are used only where really constant resilience is required.

Abstract: D-22,258 DC-TO-DC CONVERTER WITH REDUCED POWER                   LOSS DURING TURN OFF     by Neale A. Zellmer ABSTRACT OF DISCLOSURE          The base electrode of the switching transistor in a converter is resistively connected to the output terminal of a pulse width modulator and connected through first and second series connected diodes to a ground reference potential which is also connected to the emitter of the transistor, the junction between the diodes being electrically connected through a large capacitor to the modulator output terminal.  Voltage pulses at the output terminal cause the transistor to pass collector current and the second diode to conduct for charging the capacitor.  On termination of voltage pulses, the modulator connects the output terminal thereof to ground.  This causes the charge voltage on the capacitor to turn the first diode on to pull the base voltage sharply negative for rapidly drawing minority carriers out of the base region.  This allows the base-emitter interelectrode capacitance of the switching transistor to discharge sooner for rapidly reducing the flow of collector current and decreasing power dissipation in the transistor during turnoff thereof.

Abstract: RMR1??79 PP 39 ?                         TITLE              ANESTHESIA MACHINE HAVING PROPORTION LIMITING CONTROL SYSTEM     ABSTRACT       A system is disclosed for providing an interconnection between two needle valves such that movement of either needle valve, in opening or closing thereof, is affected or limited by movement of the other valve.  The invention is particularly suited to an anesthesia machine wherein separate supplies of oxygen (O2) and nitrous oxide (N2O) are fed to individual needle valves which are then individually adjusted to provide a desired mixture of N2O and O2 for administration to a patient to anes-thetize the same.  The system herein disclosed interconnects the individual needle valves such that the O2 needle valve may be opened fully without restriction, however, when the N2O valve is open, the interconnection provides that closing of the O2 valve will, at a predetermined point, also correspondingly close the N2O valve, thus preventing the percentage of N2O in the mixed gas from raising above a set value, i.e. one at which sufficient oxy-gen for a respirable mixture is assured. Similarly, the N2O valve is prevented, through the same interlock system, from being opened beyond a point where the N2O percentage could exceed such limit.          Again, when the N2O valve reaches the predetermined point, fur-ther opening of the N2O valve also opens the O2 valve such that the flow can be increased by further opening of the N2O valve but the percentage of N2O and O2 will thereafter remain constant.  In addition, the overall system has a further preventative feature where the flow of oxygen cannot be set below a predetermined value so that sufficient oxygen flow to the patient is assured.
