Patent CA-2090316-A1 (CA)
Title: Photographic processing apparatus
Inventor: GLOVER EDWARD C T S
IPC: G03D3/06
Filed: 1992-06-22
Abstract: In photographic processing apparatus in which continuous processing is carried out in a tank having a low volume, it is difficult to obtain sufficient agitation of the processing solution. This problem arises because processing solution adheres to the emulsion surface of the material being processed, and access of fresh processing solution to the emulsion surface is restricted in the narrow confines of the tank. Described herein is an arrangement in which the agitation of the solution is improved. The arrangement includes an element (16) which is positioned over a feed slot (18) through which processing solution enters the tank (10). The element (16) serves to keep the emulsion surface (26) of the material (24) being processed away from the tank wall (14) and allows access of processing solution to the emulsion surface.

Title: Fuel Activation Apparatus Using Magnetic Body
Inventor: JEONG TAE Y
IPC: C10L1/06
Filed: 1993-09-10
Abstract: Disclosed is a fuel activation apparatus using a magnetic body, capable of ionizing fuels so as to obtain high combustion efficiency for a liquid or gas fuel. In the fuel activation apparatus, a fuel activation member of a magnetic material to make the fuels rotatably flow is inserted into the inner side of a fuel activation duct through which the fuels flow. A magnetic body is disposed on the external side of the fuel activation duct. A magnetic induction layer encloses the magnetic body and the fuel activation duct. Further, a magnetic shield layer is disposed in the external side of the magnetic induction layer. Thus, the ionization of the fuels which flow through the fuel activation duct is maximized, thereby heightening the combustion efficiency of the fuels.
Patent CA-2106153-A1 (CA)
Title: De-chlorinated water supply system
Inventor: SLOAN FRANK P
IPC: C02F1/76
Filed: 1993-09-14
Abstract: ABSTRACT     The likelihood of proliferation of micro-organisms in a downstream conduit connecting the outlet of a chlorine filter to a de-chlorinated water outlet in a water supply system when no water is flowing in the conduit is reduced by providing a by-pass conduit between the upstream conduit and the downstream conduit.  The flow of chlorinated water through the by-pass conduit is prevented when water is flowing from the chlorinated water inlet through the upstream conduit, the filter and the downstream conduit to the de-chlorinated water outlet.  Chlorinated water in the upstream conduit is permitted to communicate through the water in the by-pass conduit with de-chlorinated water in the downstream conduit when no water is flowing in the upstream conduit, the filter and the downstream conduit to enable chlorine in the chlorinated water in the upstream conduit to migrate through the water in the by-pass conduit into the de-chlorinated water in the downstream conduit to reduce the likelihood of proliferation of micro-organisms therein.

Title: Method and apparatus for debanding a bale
Inventor: HALL RICHARD W
IPC: B65B69/00
Filed: 1992-07-17
Abstract: 2113180 9301911 PCTABS00019 A bale debanding device (12) having a band breaking blade (42), a band winding mandrel (16), and a mandrel cleaning plate (36) are mounted to a frame (14). A support table (26) is attached to the frame (14) for receiving a bale of used paper product (28) that is held together by banding material (30). As the bale (30) is moved past the band breaking blade (42), a band retention notch (68) engages a band (30) and by stretching it, breaks the band (30).  Once a band (30) is broken, an extensible/retractable band catch (18) extending from the surface of the mandrel (16) engages the band (30) and facilitates the winding of the band (30) around the mandrel (16). Once all bands (30) have been removed from the bale (28), the band catch (18) is retracted to a position within the mandrel (16), a protective hood (47) is pivoted away from the mandrel (16), the mandrel (16) is elevated to meet the mandrel cleaning plate (36) and the cleaning plate (36) is moved axially along the mandrel (16), sweeping the bands (30) off a free end of the mandrel (16). This process is repeated to remove bands from other surfaces of the bale, thereby releasing the waste paper in preparation of processing.

Patent CA-2122843-A1 (CA)
Inventor: BAKER WALTER J
IPC: G07F7/08
Filed: 1994-05-04
Abstract: A system for providing items of value, charging the items to a smart card, and for recharging the smart card. The system includes a station for providing the items of value, which may be postal services, and debiting the cost of the items to a smart card; the smart card being charged with funds equivalent data.  The station also communicates with a Data Center for recharging the smart card.  Users of the system communicate with the data center to request recharge of a particular smart card and in response to an authorized request the data center generates an encrypted authorization message which includes an identification number, the amount of recharge requested, and control data which preferably includes a control sum formed by adding the amounts stored in a descending register, which stores the amount available on the smart card, and an ascending register which stores the total of the amounts by which the card has been charged since initialization.  Thus, the authorization message may be used only once.  From time-to-time the Data Center transmits authorization messages to each station on the system.  When a particular smart card for which an authorization message has been received is connected to a station, the smart card compares the control data with the control data stored on the smart card and if there is a match updates the funds equivalent data in the descending register of the smart card.  To provide security against transmission of false authorization messages to a station, the authorization messages are encrypted, preferably using a public key encryption system.
