Abstract: ABSTRACT OF THE DISCLOSURE           The reaction of a polyfluorocarbonyl compound such as a polyfluoroketone or polyfluorocarboxylic acid fluoride with fluoride ion and a polyfluoroallyl chloride or fluorosulfate produces a polyfluoroallyloxy compound, e.g., CF2=CFCF2OCF2CF2SO2F.  The polyfluoroallyloxy compounds copolymerize with ethylenically unsaturated monomers such as tetrafluoroethylene, chlorotrifluoroethylene or vinylidene fluoride to form polymers which are moldable, and in some cases electrically conducting or are water-wettable and dyeable.

Abstract: FOOD PREPARATION APPARATUS       AND PROCESS     Abstract Of The Invention The invention relates to an apparatus and process for preparing wholesome meals for patients in hospitals, rest homes, airline passengers, prisoners and the like.  A portable cart or cabinet with access doors has serving trays supported on heater shelves which trays support the food items to be served to the patient.  Each tray contains food items in noninsulated dishes which items are either to be heated and served hot or not to be cooked and served cold.  All of the dishes are refrigerated while the food items to be served hot are heated.  The dishes containing food items to be heated or cooked carry noninsulated covers or lids.  The food items are normally placed on the tray in refrig-erated condition.  Chilled air for the cart or cabinet is provided by a self-contained or remote air chilling device to a plenum chamber which chamber when coupled continuously circulates chilled air from the chilled air device into and through the cart and then back through the plenum chamber to the chilled air device in a continuous closed loop pattern.  The circulating air passes through mating vents and inlets of the plenum chamber and the cart which automatically open when the cart is coupled with the plenum chamber.  The heating for each food item to be served hot is initiated, time controlled and terminated by a programmed computer which separately controls the operation of the individual heater plates mounted on the heater shelves supporting the trays.  The heating plates contact the bottom of the dishes to be served hot through dish supporting holes in the tray.  The heating plates are slightly raised above the heating shelf surface which positions the dishes to be served hot out of contact with the tray so that heat from the dishes being heated cannot migrate to the tray and the remaining food items on the tray which are to be served cold. The food carts or cabinets containing the food items on serving trays can be initially connected to mating plenum chambers or a refrigerated area in the food preparation area, then removed and sent to designated areas of the hospital, for instance, where they are positioned into plenum chambers having a control unit at which area a computer control unit takes over and initiates the cooking of those foods to be served hot. One food cart or cabinet may contain meals for a number of patients or other type consumers and the rethermalization of these meals throughout the day is con-trolled by the programmed computer unit.  ,, ,

Abstract: ABSTRACT OF THE DISCLOSURE     This invention relates to apparatus for terminating a plurality of insulated conductors in respective insulation-piercing contact portions of electrical connectors.  Prior art termination apparatus are not completely satisfactory for ter-minating electrical connectors having different transverse widths.  Further, such apparatus do not equalize the forces applied across a connector by the members used to insert the conductors.  The present invention provides a field termination tool for electrical connectors and includes laterally floating combs having edges which engage respective longitudinal slots on each side of the electrical connector to define a reference plane.  The connector is urged toward the reference plane by a blade spring carried on the connector support.  The insertion tool forces insulated conductors into respective insulation-piercing portions of connector contacts equally well for dif-ferent connector widths by apparatus for positioning one of a pair of oppositely directed rotatable insertion arms with res-pect to the other and to the connector support, and by a floating support structure to equalize forces across a con-nector.  The comb slots each have a cutting edge which is  co-operable in a scissor action with the cutting edge of the in-sertion blades carried on the insertion arms to cut the con-ductors immediately prior to insertion.  The insertion arms are forced perpendicular to their planes of rotation to prevent parting of the cutting edges during the cutting operation.

Abstract: FLUID PRESSURE CONTROL VALVE DEVICE ARRANGED FOR FAIL-SAFE OPERATION                    ABSTRACT OF THE DISCLOSURE      In a proportioning type control valve device in which a piston valve assemblage is actuated to service position in accordance with a differential between brake pipe and control reservoir pressures on opposite sides of an actuating piston abutment forming a part of the piston valve assemblage, there is provided on the control reservoir side of the piston abutment a bellows device that is normally held under com-pression by the presence of control reservoir fluid pressure so as to be normally disengaged from the piston and engage-able therewith only in the absence of control reservoir pres-sure to serve as the reference against which reductions in brake pipe pressure are measured to establish the actuating force on the piston abutment.  When disengaged from the piston abutment under the influence of the control reservoir pressure, the bellows holds a control spring housed within the bellows under compression.  This control spring acts through the bellows to provide the desired reference force on the piston abutment in the absence of sufficient control reservoir pres-sure to hold the bellows under compression.

Abstract: ABSTRACT OF THE DISCLOSURE           The subterranean fragmented and pervious zone is formed beneath an overburden which, as a first step of the pro-cess, is lifted as a substantially monolithic land mass to produce a void space and a free space proximate the rock to be fragmented, the raised overburden thus providing a sub-stantially impervious lid or closure for the fragmented zone as formed by the present invention.  Explosive charges are then placed proximate to and for blasting against the free face formed on raising the overburden.  The charges are exploded to fragment the rock to distribute the space, thus producing fractured, pervious rubble-ized rock in a defined and enclosed zone.  Different techniques are disclosed for the critical raising of the overburden and subsequent frag-menting of the rock.
