Abstract: A quick disconnect connector for use with a system for measuring depth of anaesthesia of a patient. For this purpose, a probe is attached to a patient to detect esophageal contractions. The probe is connected to a patient station by means of flexible tri-lumen tubing. The patient station provides a pressure transducer, a source of pressurized air, and a thermistor connection, and in turn is operatively connected to a microprocessor which controls the entire operation. One conduit of the tubing enables communication between a liquid filled balloon within the probe and the transducer at the patient station. Another conduit enables an air balloon within the probe to be connected to the source of pressurized air. Still another conduit receives the electrical lead which extends to the thermistor.

Abstract: Hectograph master webs and sheets formulated to provide sharper, more-complete transfer under reduced imaging pressures, and sharper, more-numerous duplicate copies in the hectograph duplicating process and resistance to adhesion and coating-transfer under the pressures exerted by a hectograph duplicating machine. The receptive surface formed on the master sheet comprises a hard, pressure-adhesive coating consisting by weight essentially of 45 to 65 percent paraffinic wax, 5 to 20 percent hard wax and 15 to 40 percent polybutene polymer having a Staudinger molecular weight of from 10,400 to 12,300 which bonds to the hectograph transfer layer under relatively low, localized imaging pressure but which is sufficiently hard to resist adhesion, sticking and pick-over to hectograph copy sheets during the hectograph copying processes. The receptive coating also provides a barrier against the migration of the hectograph composition and/or of the spirit duplicating fluid into the master sheet.

Abstract: An elongate apparatus for forming a plurality of plastic bags or pouches from a continuous length of thermoplastic film, in which the moving film is folded to form a double thickness which is open inwardly from one edge, and is folded inwardly from said one edge to form a flap ply which is treated at a plurality of aligned workstations to form physical bag features, such as to form spaced hanger-receiving slits, insert spaced hangers, form a longitudinal hanger-confining heat seam, fold out the flap ply, apply spaced adhesive closures, form V-cuts in the flap ply and fold back the flap ply to overlie the double ply prior to forming heat-seal transverse cuts which segregate the web into a plurality of plastic bags or pouches.

Abstract: An electrical conductor contact having opposed cantilever fingers configured to mate with a mating contact at a low mating force is provided. Each finger has a contact portion at its free end. The contact portions are offset axially from each other in the longitudinal direction of insertion of a mating contact thereby permitting the surface of the contact portion of the upper finger to be located below the surface of the contact portion of the lower finger. The contact portions are also preferably offset axially from each other along the other spatial axes. The contact configuration reduces the maximum mating force and permits plating of the contacts with a minimum amount of precious metals. The invention further provides a receptacle connector for low force mating with a pin header in printed circuit board applications which is comprised of a plurality of electrical contacts so configured, and a specially configured housing for housing and preloading the plurality of electrical conductor contacts.

Abstract: Method and apparatus for assembling electrical connectors of the dual in-line type wherein contacts are separated from a contact strip and inserted into contact openings in the connector body. The contacts are arranged in the contact strip at a lesser pitch then the pitch of the openings that they are received into on the body. Means and methods are described to separate the contacts from the strip and align them with their respective openings of the body to which they are assembled.

Abstract: A dual-in-line connector assembly of the closed-entry, closed-bottom type having an integral structure comprised of a base and a body of closely conforming configuration.

Abstract: A device for the lifting of liquid solely by the use of solar energy is constructed of two vertically disposed pipes, one pipe extending below the surface of the liquid and the second pipe extending above the surface of the liquid. A third pipe, in the form of a transverse section, joins the top of the first pipe and the bottom of the second pipe, the transverse section being inclined to provide entrapment of liquid therein upon submergency of the first pipe. A liquid inlet is provided at the bottom of the first pipe and an air vent is provided at the top of the first pipe at the junction thereof with the transverse section. A discharge port for liquid is provided at the top of the second pipe. An air pressure differential is established between the vent and the discharge port for forcing liquid from the transverse section to the port.

Abstract: A duplex reproduction system which produces duplex copy sets in collated separated stacks from a stack of precollated documents includes a document feeding apparatus which feeds a stack of documents individually onto the platen of a copy processor for producing copies of each document. The copy sheets are transported to a receiving tray in a sorting apparatus which does not sort the copy sheets when producing the first side of the duplex copies. As an improvement, the copies are cleaned on the back (non-image) sides thereof to remove unfused toner. The documents are reloaded into the document feeding apparatus for feeding the documents with the second side onto the platen of the processor. On the simplex or first pass a circuit disables the sorting function of the sorting apparatus. The copy sheets are removed from a single receiving tray of the sorter for a second or duplex run.

Abstract: A method and apparatus is disclosed for synchronizing copy substrate positioning with an image position on a photoreceptor in an electrostatic copier that includes primary rollers which drive intermittently at a slower speed than copier process speed while feeding a copy substrate to the photoreceptor. Secondary rollers which are located between the primary rollers and the photoreceptor drive the copy substrate continuously at the process speed. After the copy substrate enters the secondary rollers, the primary rollers stop driving and allow the copy substrate to continue in travel by the driving force of the secondary rollers in synchronism with the image on the photoreceptor.

Abstract: Drum support apparatus including outboard and inboard hubs having outer surfaces adapted for interface fitting with the inside surface of a drum. The hubs while being supported on a shaft that is cantilevered from a frame have recessed areas on central portions thereof to cooperate with locking tabs located on a tubular member loosely fitted on the shaft whereby rotation of the hubs by approximately 20.degree. creates a semi-rigid assembly that is rigidly secured to the shaft by the tightening of a single nut at the center of the drum. An assembly of this type creates an equal distribution of force on the hubs, thus diminishing circular run-out of the drum.

Abstract: A method and apparatus for providing duplex copies in pre-collated output copy sets from a set of documents recirculated in order by first copying only the even-ordered documents in the set once onto the first sides of substrates and transporting those copies to a buffer; then making individual copies in order of all the documents by alternately copying odd order documents on the reverse side of copies fed from the buffer while alternately copying even ordered documents onto copy substrates fed from a different copy substrate source, and transporting the copies made from the buffer to an output tray to create pre-collated sets while simultaneously transporting the copies from the other copy substrate source to the buffer to replace the copies fed therefrom; repeatedly individually copying all of the documents in the set in the latter manner by a number of document recirculations equal to one less than the total number of copy sets desired, and then, for a last copy set, making copies of only the odd ordered d

Abstract: Microfield donors used in a xerographic process and the methods for manufacturing them. The donor is provided with means for establishing a plurality of electrostatic microfields on the donor surface to attract and hold toner particles so they can be transported to a developing station. The polarity of the established microfields are continuously reversed to alternately repel and attract toner particles to the donor surface during their transportation in order to agitate the toner particles to prevent agglomeration of the particles from forming and to effect nullification of the microfield attracting the particles adjacent a photoconductor to form a high density image free of background deposits in uncharged area of the photoconductive surface.
