There is an outside operating member connected to the latch mechanism for causing operation thereof and there is an inside operating member connected to the latch mechanism for causing operation thereof. A deadbolt mechanism is mounted in a second bore in the door, which second bore is spaced from the first bore. The deadbolt mechanism has a deadbolt which is automatically movable to an extended position when a portion of the deadbolt mechanism contacts a door strike. The deadbolt mechanism includes a swivel and there is a spindle in engagement with the swivel for retracting the deadbolt. An interconnected assembly connects the inside operating member and the spindle whereby movement of the inside operating member both operates the latch mechanism and moves the deadbolt to a retracted position.

Abstract: Low-flux-leakage cables and cable terminations for an A.C. electrical heating system that heats a fluid reservoir around a mineral fluid well, usually an oil well; the system utilizes A.C. electrical heating power in a range of 25 to 1000 Hz. The well has a borehole extending down through overburden formations and through a subterranean fluid reservoir; the well includes an electrically conductive upper casing in the overburden, an electrically conductive heating electrode located in the reservoir, and an electrically insulating casing between the upper casing and the heating electrode. The cable extends down through the upper casing and is connected to the heating electrode to supply electrical power to the electrode. The power cable has two or three electrical conductors which are electrically isolated from each other, enclosed within a steel sheath.

Abstract: A voltage compensation device for a two-conductor A.C. power line supplying one or more air conditioners, a telephone system or other telecommunication system, or some other utilization system that requires an input voltage within a given range. The device includes a transformer having electromagnetically coupled primary and secondary windings with the primary and secondary each connected to at least one output terminal. One winding is connected to add voltage to the A.C. line voltage when the line voltage drops below a given low voltage threshold, and in bucking (subtractive) relation when the A.C. line voltage exceeds a given high voltage threshold. When the A.C. line voltage is in the range required by the utilization system, the one winding is effectively shorted out or otherwise disconnected. A sensor for the line voltage actuates one or more relays connected to the transformer to effect the desired compensation action.

Abstract: A method of manufacture of a long radial-flow filter particularly suitable for use as an input filter in a subterranean fluid (oil, gas, water) well starts with a length of multi-perforate pipe, which may be an integral part of the well 's production tubing. The pipe is mounted in an engine lathe with the perforated length between the headstock and the tailstock of the lathe. With the pipe rotating, a strip of metal (steel) wool is wrapped around the pipe in repeated, overlapping helical layers each aligned at an acute angle X to the pipe axis, with adjacent layers angularly displaced by 2X. The completed filter has a tubular wire mesh around the pipe, between the pipe and the innermost layer of steel wool, and a multi-perforate sheath over the outermost layer of wool.

Abstract: A sweeping machine includes a housing, wheels for moving the housing and a sweeping brush mounted on the housing. There is a hopper positioned adjacent the brush to receive dust and debris from the rotating brush. A dust collection chamber is located on the housing and a vacuum fan mounted on the housing creates an air flow path from the brush through the hopper into the dust collection chamber. A filter element is positioned in the air flow path with the filter element including a plurality of generally parallel pleats extending in a direction transverse to the air flow path. There is a plurality of electric coils positioned adjacent the pleats. A plurality of metal elements are associated with the pleats. Pulsed electric power is applied to the coils with the electromagnetic fields caused thereby moving the metal elements reciprocally back and forth and the pleats associated therewith to impart a shaking, cleaning movement to the pleats.

Abstract: A system for detecting an incipient tumor in living tissue such as that of a human breast in accordance with differences in relative dielectric characteristics. A generator produces a non-ionizing electromagnetic input wave of preselected frequency, usually exceeding three gigahertz, and that input wave is used to illuminate the living tissue, being effectively focused into a small, discrete volume within the tissue to develop a non-ionizing electromagnetic wave at that position. The illumination location is moved over a portion of the living tissue in a predetermined scanning pattern. Scattered signal returns collected from the living tissue are collected to develop a scattered return signal. The scattered return signal is employed to detect any anomaly, caused by differences in relative dielectric characteristics, that is indicative of the presence of a tumor in the scanned living tissue.

Abstract: A versatile high speed slicing machine moves first and second food loaves along parallel loaf paths into a slicing station where both loaves are sliced by a cyclically driven knife blade. There are independent loaf feed drives so that slices cut from one loaf may be thicker than slices from the other. The conveyor/transfer system onto which food loaves are deposited as cut includes a receiver located below the slicing station; a lift mechanism moves the receiver down during slicing so that slices always fall about the same distance after being cut. The receiver includes a plural-belt horizontal receiver conveyor with recieving pin wheels located between the belts that periodically discharges groups of food loaf slices onto a deceleration conveyor, from which the groups are fed onto a multi-belt scale conveyor. The scale conveyor is aligned with two receiver weighing grids, each grid including plural grid elements interleaved one-for-one with the scale conveyor belts.

Abstract: A quick connector coupling for forming a joint in a fluid line includes a hollow plastic connector body extending between a male member connection end and a hose connection end. A male member received in the connector body and has an enlarged annular upset. A retainer is associated with the connector body and secures the male member in the connector body. The retainer has one or two locking loops which extend beyond the male member connection end and encircle a portion of the upset to prevent withdrawl of the male member. The retainer may be attached to the interior or exterior of the connector body, and may be made of plastic or metal.

Abstract: A pouch machine forms a series of pouches in a continuous web of pouch material by folding the web and then forming spaced side seals to define a pouch closed on three sides with an initially unsealed mouth on top. The pouch is opened to its maximum volume prior to filling by pressurizing the pouch. Pressurization is achieved by introducing a curtain of compressed air under a plate and passing the mouths of the pouches adjacent the plate and thus through the air curtain. The air curtain is preferably at least as wide as the mouth so the entire mouth is subjected to the air pressure, thereby causing the pouch to inflate to its maximum volume. Continuous web height control is provided to assure alignment of the web with the plate. A lip at the mouth may be formed by folding one edge of the pouch over prior to creation of the side seals. After filling the lip is folded back up prior to top sealing to make a balanced pouch.

Abstract: A water input connection for a faucet includes a body which has a water inlet and a water outlet. There is a chamber within the body and there is a seat adjacent the water inlet. An antisiphon check valve is movable within the body chamber toward and away from the seat to open and close the water inlet connection. There is an antiflow valve movable within the body to open and close the water outlet connection. A spring is positioned within the body and biases both the antiflow valve and the antisiphon valve toward water inlet and water outlet closing positions.

Abstract: A secondary seal for use in a high temperature and pressure environment, including only non-elastomeric elements, such as an annular wound spring essentially enclosed on three sides by a polymer cladding. Two lips surround the spring, while permitting an exposed spring section to maintain direct contact with a radial wall surface of a disc which retains the secondary seal disposed annularly around the back face of a seal primary ring. Optional ridges having flat sealing surfaces on one sealing surface of the secondary seal defines a number of discrete annular cells to provide a cascading pressure profile across the sealing surface.

Abstract: A modular seal assembly for sealing a circular opening through a wall, usually with one or more conduits (i.e., telecommunication cables) extending through the seal. The assembly includes an outer pressure annulus and a thick inner pressure disc, both of natural or synthetic rubber, EPDM, urethane, or other elastomer. In the outer annulus the elastomer is an annular series of interconnected blocks of length L1 having a central opening of radius R2; a series of pressure bolts compress the blocks axially, expanding the annulus both outwardly and inwardly. The inner disc, which has an outer radius of about R2 and is interlocked with the elastomer blocks of the outer annulus, has a multiplicity of circular layers, much like an onion; the layers are concentric about an opening through which a conduit usually extends.

Abstract: A slicing station for a high speed food loaf slicing machine that slices one, two, or more food loaves simultaneously using one cyclically driven knife blade; the slices are stacked or shingled in groups on a receiving conveyor located below the slicing station. Independent loaf feed drives are provided so that slices cut from one loaf may be thicker than slices from the other. The slicing station, enclosed by a housing except for a limited slicing opening, includes a knife blade having an elongated arcuate cutting edge and a drive that moves the knife blade at a predetermined cyclic rate along a closed cutting path through the slicing range, which range intersects the ends of food loaves fed at predetermined rates into the slicing station. A marker moving with the blade is sensed by a fixed sensor to establish a home position for the blade. There is a honing device to sharpen the cutting edge of one type of blade, with the blade in its home position.

Abstract: A menu stand or like device is employed as a signal device to summon a waiter to a table in a restaurant or like establishment. The device includes a housing having a base that supports it on a table and a low-energy demand light source. The light source is preferably a thin electroluminescent (EL) surface element mounted on a menu holder that is a part of the housing. A D.C. battery, removably mounted in the housing base, energizes an inverter that generates an A.C. energizing signal that is applied to the light source. Preferably, the A.C. energizing signal pulsates at a low frequency. There is a switch, normally open, that turns the light source ON to summon a waiter.
