Abstract: ABSTRACT      A closure for a bag (not shown), such as a plastic bag for freezing shaped lumps of ice for cooling drinks, consists of  a  channel  member  adapted  to  receive  an insertion member.  Before the insertion member is pressed into the channel member, the end of the bag (not shown) is inserted between the two, being closed in a fluid-tight manner  when  the  two  members,  in  the  example  shown interconnected by a hinge,  are pressed together.   The closure makes it possible to close bags for freezing ice lumps in a fluid-tight manner, allowing the bags to lie down in a deep-freeze cabinet without leaking and also making it easier to open the bags than when these are closed by means of knots or the like.

Abstract: ABSTRACT     A filter apparatus and method is provided wherein a tank is adapted to receive unfiltered liquid.  An outlet chamber is located adjacent the bottom wall of the filter tank and is separated therefrom by a perforated plate.  A filter media is movable across the rear, bottom and front walls of the filter tank and accordingly, unfiltered liquid must pass through the filter media as well before entering the outlet chamber.  A chain flight assembly is provided which is movable across the filter media along the rear, bottom and front wall  of the filter tank.  As the chain flight assembly is continuous, a return path is across the top of the tank above the unfiltered liquid.  A baffle plate is provided near the rear  wall within the filter tank.  This baffle plate extends sideways to near each side wall of the filter tank, upwardly above the level of the unfiltered liquid within the filter tank and downwardly to a point just above the flights of the chain flight assembly above the filter media at the bottom of the filter tank.  A spray header is provided to spray filtered liquid between the rear wall of the filter tank and the baffle to prevent unfiltered liquid from bypassing the bottom of the baffle and entering the outlet chamber without passing through the filter media.  Another spray header is provided to wash the chain flight assembly while it passes above the filter tank.

Title: Catalytic converter for a diesel engine

IPC: F01N3/022
Filed: 1987-05-01
Granted: 1990-12-11
Abstract: CATALYTIC CONVERTER FOR A DIESEL ENGINE     ABSTRACT OF THE DISCLOSURE    A catalytic converter for a diesel engine comprises a labyrinth made of metal foil.  The foil is coated with an oxidation catalyst.          When exhaust gas flows through the labyrinth, the gas is forced to make right-angle turns at intervals as short as about 5 mm.  The number of right angle turns can be as great as 30 turns per cubic centimeter of labyrinth. These abrupt turns cause particulates in the gas to be deposited on the foil.  At intervals, fuel is injected into the exhaust gas.  The fuel burns on the catalyzed surface and heats the converter sufficiently to burn the trapped particulates.  In an alternative embodiment, there are two converters, and fuel is automat-ically injected into that converter which has more trapped particu-lates than the other, so as to burn the particulates trapped in that converter.

Abstract: BEAM-FORMING NETWORK                    ABSTRACT OF THE DISCLOSURE A satellite communications system employs separate subsystems for providing broadcast and point-to-point two-way communications using the same assigned frequency band. The broadcast and point-to-point subsystems employ an integrated satellite antenna system which uses a common reflector (12). The point-to-point subsystem achieves increased communication capacity through the reuse of the assigned frequency band over multiple, contiguous zone (32, 34, 36 38) covering the area of the earth to be serviced. Small aperture terminals in the zones are serviced by a plurality of high gain downlink fan beams (29) steered in the east-west direction by frequency address. A special beam-forming network (98) provides in conjunction with an array antenna (20) the multiple zone frequency address function. The satellite (10) employs a filter interconnection matrix (90) for connecting earth terminals in different zones in a manner which permits multiple reuse of the entire band of assigned frequencies. A single pool of solid state transmitters allows rain disadvantaged users to be assigned higher than normal power at minimum cost. The intermodulation products of the transmitters are geographically dispersed.

Abstract: PATENT           ABSTRACT          An electronic entertainment device which allows an untrained vocalist or instrumentalist to easily synthesize an instrumental lead, and optionally, one or more harmonies, simultaneous with the lead, playing along with predefined background musical sequences.  While the background parts to a song are being played by the device, or any outside musical player, the user plays the melody, or "lead", by humming, singing, whistling, or operating any tone-producing device, such as a musical instrument, into the device.  The device then identifies the pitch, compares it with a table of allowable pitches, as dictated by predefined data associated with the background music, chooses an appropriate output tone, and drives a music synthesizer to play the chosen instrument at the determined pitch, in accordance with the allowable pitches.  The note which is produced by the device is one which sounds pleasing in the context of the musical back-ground.  The device facilitates an active involvement in music expression without a need for well developed skills as a vocalist or instrumentalist.

The primary agent is a vasodilator selected from the group consisting of papaverine, hydralazine, sodium nitroprusside, phenoxybenzamine and phen-tolamine. The carrier is used to assist absorption of the primary agent through the skin around the penis. When the primary agent enters the corpora cavernosa within the penis, it causes dilation of the corpora, resulting in an erection.

Abstract: TREATMENT OF AGED SKIN             Abstract of the Invention Various disorders of the human skin, particularly facial skin, of elderly individuals, may be treated with low doses of 13-cis-retinoic acid by oral administration in amounts which are non-toxic and non-teratogenic.  The disorders are those which appear in the elderly and are complicated by excessive sun exposure (photoaging), including sebaceous gland hyperplasia, follicular Demodex infestation, bacterial and fungi-induced folliculitis, rosacea-like and seborrheic-like dermatoses and dandruff-like scalp conditions.  The treatment is effective at doses of as low as 1-5 mg daily or every other day, and is preferably used with women beyond childbearing potential, and males over about 50 years of age.  The treatment also retards and reverses hyperkeratosis, epidermal atrophy, and other skin changes of the elderly.

Granted: 1993-04-20
Abstract: BLOOD CENTRIFUGATION CELL                     ABSTRACT    A blood centrifugation cell has an outer container, a volume displacement inner body having a central passage, and an inlet conduit extending through the central passage to the bottom of the container.  A seal is provided at the lower end of the body sealing the space between the inner conduit and the central passage.  The seal permits red blood cells to be sucked from the container at any time during centrifugation without waiting for the cell to become completely filled.
