Title: Method of producing a foamed polymer
Inventor: FOSTER RICHARD J
IPC: B29C44/08
Filed: 1989-10-05
Abstract: ABSTRACT     A process for producing a foamed polymer, particularly a foamed polyofefin, of highly uniform low density.            A mixture of a polymer-forming material, a cross-linking agent, and a blowing agent is placed in a mould and reacted.  This reaction product is cooled until the differential temperature between core and surface is below a predetermined maximum, and removed from the mould.            The cooled product is then subjected to dielectric heating, preferably by microwave irradiation, to cause uniform heating and highly uniform expansion to produce a foamed polymer of highly uniform low density.            The process of the invention enables production of relatively thick foamed polymers with a uniformity of density not possible with conventional foaming processes wherein high differential temperatures lead to non-uniform densities and distortions of the foamed product.  The process of the invention also avoids the serious problems with excessive pressures encountered in attempting to produce highly foamed polymers in single-stage processes carried out entirely in closed moulds.

IPC: B67C3/10
Filed: 1989-10-24
Abstract: In apparatus for filling cans with beverage the can is coupled to the filler valve and purged of atmospheric  air with  a mostly  inert  gas and air mixture derived from the space of the liquid in a storage tank.   When the exhaust valve is closed, another valve opens to permit pure inert gas stored in a reservoir to flow into the can and pressurize it to slightly above atmospheric pressure but below the pressure in the storage tank.  A pre-pressurization valve is then opened to let some of the inert gas and air mixture in the storage tank flow to the can which is occupied by the substantially pure inert gas so practically  none  of  the  downflowing  gas  and  air mixture from the storage tank enters the can although it fills the chamber to which the can is connected and thereby pressurizes the can.  When the can pressure and  storage  tank pressure become  equal,  a  liquid control valve opens to drain liquid from the tank into the can.  Liquid flow is shut off in a conventional manner when the liquid level in the can reaches the lower tip of the pre-pressurizing gas return tube.  as the liquid beverage flows into the can it displaces the most pure inert gas into the space above the liquid in the storage tank so as to increase the concentration of the inert gas in the storage tank.

Title: Gas fired convection oven with improved air delivery and heat exchange structure
Inventor: YENCHA MICHAEL V III
IPC: F24C15/32
Filed: 1989-11-16
Abstract: ABSTRACT A gas fired convection cooking oven is provided with an improved air delivery and heat exchange structure for creating within the oven's cooking chamber a recirculating flow of heated air to cook food items supported therein. The structure includes a combustion box adapted to receive hot products of combustion from a gas burner, and extending into the cooking chamber through a lower portion of a vertical boundary wall thereof. Removably secured to the combustionbox, and extending upward along the inner side of the boundary wall is a hollow baffle structure having a front mixing chamber communicating with the interior of the combustion box through spaced apart hollow legs with a dischargeopening formed therebetween. Perforated skirt walls extending rearwardly from the mixing chamber define with the boundary wall a fan chamber which surrounds a motor-driven centrifugal fan impeller supported on the inner side of the boundary wall. During oven operation the recirculating air flow is drawn from the cookingchamber into the mixing chamber, mixed with burner combustion products and flowed into the fan. The flow is then ejected from the fan and forced into the cooking chamber through the skirt wall perforations and through the discharge opening between the mixing chamber leg portions. Removal of the baffle structurefrom the combustion box and the boundary wall conveniently exposes the fan impeller within the cooking chamber for inspection, cleaning and service purposes.

Abstract: An acoustic apparatus adapted to be heard only by a specific person or persons in one space without being worn by the user as in the case of an earphone. Sounds issuing from the apparatus do not leak to the outside and are not affected by the surrounding noise. Basically, the apparatus is arranged such that a sound source is disposed in one focus of a reflector having an ellipsoidal surface of revolution, and sounds are heard at the other focus. To increase the number of specific hearers, if the central portion of the reflector is made into a non-ellipsoidal surface of revolution, or a cross section having an ellipsoidal surface of revolution is extended orthogonally to the cross section by a predetermined length, the range of the other focus expands. In addition, by arranging a plurality of reflectors, it is possible to hear different sounds within the effective areas of the respective reflectors without mutual interference of the sounds.
Patent CA-2026309-A1 (CA)
IPC: G02B6/34
Filed: 1990-09-26
Abstract: An optical equalization receiver for countering the effects of delay distortion is realized by utilizing dynamically controllable Fabry-Perot etalon structures. By dynamically adjusting the frequency response of an etalon that is in a feedback loop configuration, the associated delay characteristic of the etalon may be used to counter the effects of delay distortion, thereby allowing higher transmission rates and transmission distances to be achieved. In one exemplary embodiment, anoptical receiver comprising a reflective Fabry-Perot etalon and a piezoelectric transducer is used in a feedback loop configuration wherein a feedback control circuit monitors an output signal from the etalon for generating a control signal representing the amount of delay needed to compensate for distortion in an optical signal incident on the etalon. Specifically, the control signal causes a change in the optical path length of the etalon that results in a shift in its frequency response for producing a delay substantially equal and opposite to the associated delay distortion.

The vehicular mounted waste compactor includes a hollow body having opposed open ends each having an intake opening for receiving waste to be compacted.  Divider walls within the interior the hollow body divide the interior into a receiving chamber and a compaction chamber with a passageway communicating therebetween.  To reduce the length of compaction stroke and the space needed for the ram, it includes a sliding cover wall movable back and forth for selectively closing and opening the passageway.  One end of the hollow body has a door against which the ram compresses the waste material.  When opened, the compressed material is discharged in the direction of ram travel.  To reduce the stroke needed for compaction and the space needed for hydraulic cylinders to move the ram, the cylinders are mounted diagonally to each other and to the direction of ram travel.
