Patent CA-2222804-A1 (CA)
Title: Conveyor belt
Inventor: MEEKER WILLIAM A
IPC: B65G15/54
Filed: 1996-05-22
Abstract: A conveyor belt (20), particularly suited to the food processing industry, includes a tension-bearing framework of transversely extending rods (36-38, 141, 168, 172, 177) connected to tension-bearing interconnected links (45) into which is attached a series of loose-fitting modular product support members (23-25, 134, 138). The product support modules include forwardly and rearwardly extending link ends (27, 30) such that successive modules are interfitted with one another. Each of the forwardly and rearwardly extending link ends are provided with slotted longitudinal openings (76, 77, 82) through which the transverse rods extend. The distance between a front wall portion defining the slot in a forwardly extending link end and a rear wall portion defining the slot in an associated rearwardly extending link end is greater than the fixed longitudinal spacing spanned by adjacent transverse rods so as to permit some relative longitudinal movement between the conveyor modules and the rods. In addition, at least one of the modules and the rods are provided with standoff elemnents (84, 136, 143, 170, 174, 179) which define a minimum contact area between the modules and the rods. This limited contact area creates larger openings between the conveyor modules and the rods such that when the conveyor belt is passed through a washing unit (15), washing sprays can effectively reach all surfaces. In addition, since the conveyor modules are permitted to shift longitudinally relative to the rods, this further enhances the elimination of debris trapping zones such that a highly sanitary conveyor belt arrangement is obtained. In addition, unique end cap members (47) are provided to prevent relative rotation between drive links associated with the conveyor belt and the transverse rods.

Title: Method and device for the production of variable amounts of a pressurized gaseous product
Inventor: ALTMEYER HORST
IPC: F25J3/04
Filed: 1996-07-18
Abstract: In the method proposed, charge air is fed to a cryogenic rectifying system (15, 16) where it is split up into its constituent gases, and a liquid fraction (31, 32) is taken off and passed into a first storage tank (33). The pressure of any suitable amount of the liquid fraction (34) is increased (35).  The liquid fraction (36) is then evaporated under the increased pressure by indirect heat exchange (12) and converted into a pressurized gaseous product (37). A heat-transfer fluid circulates in a refrigeration circuit fitted with a compressor (41, 42). Part (45) of the flow of heat-transfer fluid (44) compressed in the compressor (41, 42) is fed to the indirect heat-exchange unit (12) where the liquid fraction (36) is evaporated and the heat-transfer fluid (44) at least partly liquefied. Another part (59) of the flow of heat-transfer fluid (44) compressed in the compressor (41, 42) is allowed to expand (43), doing useful work. Liquefied heat-transfer fluid (45, 48) is stored in a buffer storage tank (49).

Patent CA-2239913-A1 (CA)
Title: Wdm network with control wavelength
Inventor: BARNSLEY PETER EDWARD
IPC: H04J14/02
Filed: 1995-01-26
Abstract: A wavelength division multiplex communication system comprises a head station and a plurality of terminal stations interconnected by an optical fibre cable. The head station transmits continuous wave modulated wavelengths (.lambda.1, and .lambda.k), a signalling wavelength (.lambda. 0) which is used to indicate, in each time slot, which wavelengths in the following time slot are available for transmission. Each terminal station is arranged to receive the signalling wavelength, to determine therefrom whether the next time slot contains any data packets for that terminal station and, if so, to receive the packets. The terminal station is arranged, if it has a data packet to transmit, to determine from the signalling wavelength whether the next time slot already contains data packets for the destination station and, if so, to avoid data collision by not transmitting its own data packet. The terminal station then determines a free wavelength (.lambda.  q) from the signalling wavelength (.lambda. 0) modulates the free wavelength with the data packet it is to transmit, and modifies the signalling wavelength.
