Title: Transfer system with field tailoring
Inventor: FLETCHER GERALD M
IPC: G03G15/16
Filed: 1992-10-01
Abstract: A system for tailoring electrostatic fields in and around a transfer region in an electrostatographic printing apparatus. The system includes a toner transfer system for transferring charged toner particles from an imaging surface to a copy sheet and a transfer nip and a conductive pre-nip sheet guide member, as well as a conductive post-nip sheet guide member, wherein each sheet guide member is coupled to a biasing source.      The pre-nip sheet guide member is biased to a polarity similar to the polarity of the charged toner while the post-nip sheet guide member is biased to a polarity opposite the polarity of the charged toner particles.      The invention provides for efficient and effective toner transfer while suppressing the effects of lateral conduction of transfer biases through the copy sheet under high relative humidity conditions.

Abstract: ABSTRACT OF THE DISCLOSURE A waste processing system in which containerized waste is received substantially at ground level and is conveyed to an elevator which carries the containerized waste to an upper level discharger which transports the containerized waste, dumps the containers down a drop chute and returns the empty containers to ground level.  The dumped waste is shredded and is either injected into an incinerator or is discharged downwardly.  The entire system is enclosed and can be maintained at either a negative or positive pressure for receiving radioactive or hazardous wastes, or at a reduced oxygen environment for receiving flammable hazardous waste.  Containerized waste is received through air locks which include sliding doors that are supported entirely about the peripheries when sealed for purposes of explosion resistance.  The injector discharge tube includes a slide box in which a pair of conduit segments are mounted and can be positioned such that one or the other of the segments is connected to the output conduit.  One segment connects the output conduit to an incinerator or other receiver and the other segment includes an open bottom so that material may drop vertically into a receptacle.            TDL260.PAC

Title: Method for selectively reducing subterranean water permeability
Inventor: HUTCHINS RICHARD D
IPC: C09K8/50
Filed: 1991-12-03
Abstract: Gels containing gas precursors and/or pathways are used to selectively reduce the flow of aqueous fluids with respect to the flow of nonaqueous fluids to enhance the recovery of the nonaqueous fluids from subterranean formations. The gels, while stable at reservoir conditions, are also readily degraded by gel degrading agents such as acids and therefore are also employed as fail-safe gels in subterranean gel treatments. In another embodiment, selective permeability is restored to a previously treated well by injecting a gas into the previous treated portions of the subterranean formation to displace any aqueous fluid obstructing the passage of the nonaqueous fluid through the polymer-coated pores or gel.

Title: Treatment of eating disorders by nerve stimulation
Inventor: WERNICKE JOACHIM F
IPC: A61N1/36
Filed: 1992-01-30
Abstract: A method of treating patients with compulsive eating disorders includes the steps of detecting a preselected event indica-five of an imminent need for treatment of the specific eating disorder of interest, and responding to the detected occurrence of the preselected event by applying a predetermined stimulating signal to the patient's vagus nerve appropriate to alleviate the effect of the eating disorder of interest. For example, the preselected event may be a specified level of food consumption by the patient within a set interval of time, or the commencement of a customary mealtime according to the patient's circadian cycle, or the pas sage of each of a sequence of preset intervals of time, or the patient's own recognition of the need for treatment by voluntarily in itiating the application of the stimulating signal to the vagus nerve. In cases in which the disorder is compulsive eating to excess the stimulating signal is predetermined to produce a sensation of satiety in the patient. The occurrence of the preselected event is detected by summing the number of swallows of food by the patient within the set interval of time. In cases where the disorder i compulsive refusal to eat (anorexia nervosa), the stimulating signal is predetermined to produce a sensation of hunger or to supp ress satiety in the patient.
