Patent CA-2142291-A1 (CA)
Title: Heating apparatus
Inventor: HART JOHN G
IPC: F24H1/14
Filed: 1993-08-13
Abstract: A method of heating a liquid which comprises providing a mandrel (12) within a heating element (14) having at least one surface, and passing the liquid down the mandrel in the form of a thin film (22) in such a manner that it does not contact the heating surface (14). This may be carried out in apparatus which comprises a heating element (14) within which is located a mandrel (12), not in contact with the element, a source of liquid (18), and means (20) for allowing the liquid from the source to flow over the mandrel (12) in the form of a thin film (22). The mandrel (12) will normally be maintained in a vertical orientation and the source of liquid (18) may be at the top thereof. The liquid is allowed to run as a film (22) down the surface of the mandrel (12). The mandrel (12) is surrounded by the hot surface of the heating element (14) and heat passes principally by radiant heat across the gap (16) between the hot surface of the heating element (14) to the liquid passing down the mandrel (12). Thus there is no direct contact between the liquid to be heated and any heated surface of the heating element (14). The mandrel (12) itself will normally not be heated and, indeed, it may be made from materials having good corrosion and release properties but a thermal conductivity so poor that they would not normally be used in heat exchanger manufacture. It need not be made from metal, and may, for example, be made from materials such as ceramics or glass, optionally with release coatings of, for instance, PTFE.

Title: Process for the preparation of polytetramethylene ether glycol diester using an aluminosilicate type catalyst
Inventor: MUELLER MONIKA
IPC: C08G65/10
Filed: 1993-09-03
Abstract: An improved process for the preparation of polytetramethylene ether glycol diesters of the formula R-CO-O(CH2-CH2-CH2-CH2-C7)n -COR1, in which R and R1 are identical or different and are an alkyl radical or a derivative thereof; by polymerization of tetrahydrofuran in the presence of a fixed-bed polymerization catalyst and in the presence of a carboxylic anhydride. The use of a catalyst selected from amorphous aluminium silicate, acid-activated and calcined kaolin or zeolite instead of the known natural montmorillonite catalysts having a cryptocrystalline three-layer structure means that polymers having more uniform properties and a narrower molecular weight distribution are now accessible at a higher po-lymerization rate

Patent CA-2147774-A1 (CA)
Inventor: MITRA DEBASIS
IPC: H04B7/26
Filed: 1995-04-25
Abstract: The present invention discloses a method of and apparatus for regulating the power of signals transmitted by transmitting units, such as mobiles or base stations, that are using the same channel in a cellular radio system.  An iterative process is disclosed in which the demands of synchrony and coordination among the transmitting units are relaxed.  The power of the signals converges at a geometric rate to optimal transmission powers, where the optimal transmission powers are defined as the minimum powers required to maintain the ratio of carrier power to co-channel interference power at least as large as some pre-fixed target value obtained from quality of service considerations.  As a result of relaxing the demands of synchrony and coordination, expensive clock or timing mechanisms are not required, thereby reducing the costs of power control.
Patent CA-2148143-A1 (CA)
Inventor: WOESSNER ERNST
IPC: F42B39/08
Filed: 1995-04-28
Abstract: The cartridges (1,1') are accommodated alongside each other inside close-fitting links (7), each of which has opposite protrusions (15,17), each containing an opening (11). Adjacent links hinge together via pins (9) passing through the openings and thickened at the ends. The opening in the first protrusion (15) is connected to the belt edge by a passage (13) narrower than the opening and also than the portion of the pin passing through it. A second opening in the link is connected by a second passage (13') to the belt edge. Thus by bending the passages slightly open adjacent cartridges can be slid free in either axial direction. The two passages (13,13') can lead to the same edge of the belt. The thickened portions at the pin ends can consist of transverse lugs, situated symmetrically in relation to each other. They can be rectangular, so that they cannot turn in the links.

IPC: A63B53/02
Filed: 1995-09-06
Abstract: A wood type golf clubhead includes a face, a sole, a crown, a toe portion, a heel portion, and a hosel portion adjacent the heel portion.

Patent CA-2158766-A1 (CA)
Title: Liquid transfer devices
Inventor: BUNCE ROGER ABRAHAM
IPC: B01L3/00
Filed: 1994-03-31
Abstract: The present invention concerns liquid transfer devices and, more particularly volume definition in such devices used for chemical diagnostic testing in extra-laboratory situations. In a capillary flow liquid transfer device a liquid is transported along a channel to a volume definition site, such as a sample site where sample has been applied in excess. A second channel leads to and crosses a notional area upstream of the site relative to flow in the first channel. The device is designed such that when liquid flow is initiated in both channels simultaneously, flow in the second channel reaches the interception area and carries off any excess sample before flow in the first channel reaches the interception area. This automatically prevents excess sample from being entrained in the main flow and affecting an analytical result.
