Patent CA-2145084-A1 (CA)
Title: Method and regenerator for regenerative heat transfer
Inventor: RUOTTU SEPPO
IPC: F28D19/02
Filed: 1993-09-24
Abstract: The invention concerns a method and a regenerator for transferring heat from one flow to another. The method is based on recirculating a granular heat transfer material between the circulating fluidized bed reactors of the regenerator configuration (comprising only two circulating fluidized bed reactors (A) and (B) in the basic configuration), whereby a tendency toward temperature equalization of the flows participating in the heat transfer process by entering the different circulating fluidized bed reactors is attained.   The equalization of the temperatures is controlled by adjusting the particle flows between the reactors. The mixing of the flows is prevented by directing the particles separated in cyclone chamber (5) of circulating fluidized bed reactor (A) primarily into channel (10), where the particles form a fixed bed layer. From the bottom part of the channel section (10), a particle flow of desired volume rate is controlled to move from circulating fluidized bed reactor (A) to the other circulating fluidized bed reactor (B). When the channel section (10) becomes full, the remaining portion of the particles separated in the cyclone (5) fall back into the circulating fluidized bed reactor (A). The situation and operation of reactor (B) is fully analogous.

Title: Single Vend Device for a Newspaper Vending Machine
Inventor: KAHANEK ALAN P
IPC: G07F11/16
Filed: 1995-05-04
Abstract: The application discloses a device (10) to retrofit into the cabinet (11) of newspaper vending machine racks to prevent the removal of more than one copy of the newspaper for each vend or door opening of the cabinet (11).          The single vend device (10) consists of a front panel (12) with a T-slot (14).  The arms (14a) of the T-slot (14) are normally closed off with a pivoted closure plate (16).  Con-sumer access to the newspapers is provided through the leg of the T-slot (14b), but the newspaper must be slid through the gap between the closure plate (16) and the front panel (12).  The thickness of the gap is adjustable to selectively allow for the variation in thickness between various edi-tions of the newspaper.  The closure plate (16) is spring loaded to be biased to the closed position.  Following removal of the paper, the closure of the plate (16) and a locking pin (32) prevents the plate (16) from re-opening.          The locking pin (32) is disarmed upon closure of the cabinet (11) door (25a).

Title: Containers for preparation and display of foods
Inventor: COLOMBO EDWARD ARMANDO
IPC: A47J36/02
Filed: 1995-09-14
Abstract: The instant invention is directed to a domed container and a process for using it.  The container may be used for the preparation as well as the display of food.  The food may be prepared while in the container by heating in a microwave or convection oven or by refrigeration or freezing, depending upon the type of food product it is. Unbaked pastry dough requires baking, while cheesecake requires refrigeration.  The container comprises a receptacle, a cover which locks to the receptacle, and a hollow member.  There is at least one groove in the top surface of the receptacle.  The groove is in a closed, continuous pattern, as is the hollow member.  Often the hollow member is in the shape of a ring.  The hollow member fits perpendicularly in the groove of the receptacle and is held in place by an interference fit resulting from friction between the hollow member and the sides of the groove.  Following preparation, the hollow member may be left in place or removed for decoration of the food product.  The cover is then locked to the receptacle and the food product displayed.

IPC: C07C273/04
Filed: 1995-09-21
Abstract: Process for the preparation of urea, wherein in a first step ammonia and carbondioxide react in suitable conditions so as to form a first mixture containing a quantity of urea, wherein in one or more subsequent steps ammonia and carbondioxide is removed from the first mixture and the obtained urea is concentrated until a urea concentration has been reached suitable to be granulated in a gas stream, whereby apart from urea granules a second mixture containing air, gaseous ammonia and urea dust is formed which subsequently is washed, and wherein before or during the washing an amount of formaldehyde is added to the second mixture of air, ammonia and urea under circumstances wherein the ammonia can react with the formaldehyde in order to form hexamethylenetetramine (HMTA) whereupon the so formed HMTA is separated from the gasstream and is returned into the process before the granulation step.

Title: Electronic audio/visual message prompter
Inventor: PARASKEVAS TASI ANASTASIOS NIC
IPC: G09F27/00
Filed: 1995-09-25
Abstract: When operational, the invention electronically provides to any person within its audible/ visual proximity, a repetitive audible/ visual message at user selectable but internally timed intervals.         The audible message is intended to be a composite message incorporating at least a two part statement - ie., a short duration friendly alert-tone, followed by a spoken voice message containing information relating to the surrounding circumstances.          It is intended that the invention will incorporate a facility for the user to enter his or her own unique voice message. Other forms of message can also be entered - eg., music, jingles, etc.          The audible volume of the voice message and alert-tone will be controllable by the user.          It is intended that the visual message will be triggered at the same time as the start of the tone and probably be present for the duration of the audible message. The visual message could be as simple as a set of coloured fast flashing but high intensity light emitting diodes (LEDs) directed to the target audience, or it could be something else.          The invention can be used for different and totally unrelated purpose - eg., merchandising tool, personal message device, instructional tool, security and/or safety tool, etc.          Depending on the application, the invention can exist in a variety forms which may affect its physical, audible, and visual characteristics. Notwithstanding this, it is expected that the invention will predominantly exist as a small 'palm-sized' battery operated device designed for portability and ease of use.

Abstract: In a noise cancelling device including a first subtractor for producing a first difference signal as a noise cancelled signal by subtracting a first pseudo signal from an input signal having a main signal and a first noise signal superposed on the main signal and a first adaptive filter for processing a second noise signal correlated with the first noise signal into the first pseudo signal in accordance with filter coefficients thereof, a second subtractor subtracts a second pseudo signal from the first pseudo signal to produce a second difference signal. A second adaptive filter processes the second noise signal into the second pseudo signal in accordance with filter coefficients thereof. First and second power averaging circuits produce first and second power averages of the second difference signal and the first pseudo signal, respectively. A step size calculating circuit calculates, from the first and the second power averages, a step size used for renewing the filter coefficients of each adaptive filter in deciding a rate of convergence of each adaptive filter. The first adaptive filter renews the filter coefficients thereof into renewed filter coefficients in accordance with the second noise signal, the first difference signal, and the step size. The second adaptive filter renews the filter coefficients thereof into renewed filter coefficients in accordance with the second noise signal, the second difference signal, and the step size.
