Abstract: " 1 "     ABSTRACT OF THE DISCLOSURE       The invention relates to air preheaters and discloses a preheater in which the air is heated in two stages of heat exchange, the heat source being flue gases.  Air to be heated is passed along a path having two portions.  Air in the second portion is in heat exchange relation with the flue gases and air in the first portion is in heat exchange relation with air in the second portion.  By this means, direct heat exchange between flue gases and cold air is avoided, with the consequent reduction in the risk of condensation of harmful fluids from the flue gases.  The respective portions of the air flow path are normally one within the other, enabling the conduit defining the inner portion to be removed without interfering with the flue gas ducting.

Abstract: Abstract of the Disclosure A housing of a size adapted for installation at a parking position at a shopping center or other location has an input hopper for receiving municipal trash items, particularly aluminum cans, which drop onto a conveyor and are carried to a crusher.  The crushed items drop onto a second conveyor which carries the items past a magnetic separator station which recognizes and sepa-rates out any ferrous materials.  Such ferrous items fall by gravity and in so doing to interrupt a light beam which, when interrupted, causes a photoelectric cell to generate a signal which actuates a panel on the front of the housing to inform the customer that the can he or she deposited was a steel can, not an aluminum can.  The remaining material, including aluminum cans, glass bottles, plastic cartons, paper and other items, are carried to an identification station which recognizes the aluminum items and signals a pusher mechanism to push the aluminum items off the conveyor.  The pushed-off aluminum items drop onto the platform of a weighing scale where they remain and accumulate awaiting arrival of additional items.  If a time period of preselected length passes during which no additional items are received on the scale platform, a signal is generated which is sent to a coin-payout mechanism to make payment for the weight of the aluminum items deposited on the scale.  The scale is then cleared by a rotatable indexing push-off mechanism and the separated and weighed aluminum items drop by gravity into a chute and are directed onto a third conveyor which carries the aluminum items upwardly to a storage bin located in the upper part of the housing.  When the storage bin is full, a signal is generated to indicate that the machine cannot accept any additional trash items and requires emptying. Any non-ferrous non-magnetic items, such as glass bottles, plastic containers, paper, etc., pass through the aluminum identification station and are carried by the second conveyor to a trash receptacle within the housing.

Abstract: PLASTIC CLOSURE AND RELATED CONTAINER FINISH           ABSTRACT OF THE DISCLOSURE This relates to an improvement in the neck finish of a container and skirt of a cooperating closure to eliminate or substantially reduce squaring which exists in present closure-neck finish arrangements. The neck finish is constructed so as to control the torque required to apply the closure after it has been seated, thereby hold-ing to a maximum the pressures which normally effect squar-ing.  At the same time, the neck finish is provided with a supporting surface engageable by the closure skirt so as to permit supporting of the closure skirt against the undesired squaring.

Abstract: ABSTRACT OF THE DISCLOSURE          A method and apparatus for angiography in which information contained within multiple serial images of contrast medium flowing through a blood vessel is combined to form a single image having improved vessel edge delineation.          More specifically, a method is disclosed whereby a contrast medium opaque to X-rays is injected into a blood vessel distant from an artery section of interest, preferably injected into a vein, whereby the contrast medium is mixed with blood prior to its passing through the artery section.          Multiple X-ray images are obtained as the contrast medium and blood mixture flows through the artery section.  These multiple images are registered with respect to each other according to a landmark contained within the patient, the landmark having a predetermined relationship to the vessel of interest.  The landmark could be a bone, catheter or any other material opaque to X-rays.  Density measurements are made with respect to each corresponding image segment or element of the multiple images and are combined to synthesize a composite image. The synthesized image has an edge un-certainty equal to that of one of the individual images divided by the square root of the total number of images utilized.

Abstract: MICROWAVE DETECTION OF SOOT CONTENT        IN A PARTICULATE TRAP            Abstract of the Disclosure , Conductive particulate in the form of soot are collected from diesel engine exhaust gases on a porous wall monolithic ceramic filter in such a way that the soot is somewhat uniformly distributed through-out the filter.  The filter is housed in a chamber having a property of a microwave resonant cavity and the cavity is excited with microwave energy. As the particulates are collected the cavity appears to the microwaves to have an increasing dielectric constant even though the matter being accumulated is conductive rather than dielectric so that as collected on the porous filter it has the property of an artificial dielectric.  The response of the cavity to the microwave energy is moni-tored to sense the effect of the dielectric constant of the material within the cavity to provide a measure of the soot content in the filter.
