Title: Method and apparatus for continuous flow reduction of microbial activity in a liquid product using pressurized carbon dioxide
Inventor: FORBES JAMES
IPC: C12M1/00
Filed: 1999-08-10
Abstract: A continuous method using a pressurized flow of liquefied carbon dioxide is described to reduce microbial and/or enzymatic activity in a liquid product. A flow of liquefied carbon dioxide is combined with a pressurized flow of the liquid product. The pressure and temperature in the flow regions are maintained at a level which is sufficient to keep the carbon dioxide in a continuous liquid state, but which does not freeze the liquid product.      The pressurized mixture of the carbon dioxide and liquid product flows through a reaction zone for a sufficient time to reduce harmful microorganisms and/or inactivate undesirable enzymes and then enters a plurality of expansion stages wherein the pressure of the mixture flow is sufficiently decreased to vaporize the carbon dioxide for separation from the liquid product. Heat is applied in at least some of the expansion stages to prevent a cooling of the mixture flow to the freezing point of the liquid product. Heat may be applied to control the temperature of the liquid product so that it does not exceed a temperature at which deleterious effects are experienced.

Patent CA-2282754-A1 (CA)
Title: Joining and connecting component for corrugated pipes
Inventor: KLEEB RALF
IPC: H02G3/06
Filed: 1998-02-11
Abstract: The connecting component or the connecting fitting (1) comprises at least one locking element which can be shifted-in and shifted-out radially to the longitudinal axis (14) of the fitting (1). The locking element is, for example, connected as a wing (7) via a hinge (22) with the fitting (1) or forms an additional element. On the inside face (10) of the locking element (7) are disposed a multiplicity of locking splice-clips (12) which are resilient. When a pipe end is slid into the fitting (1) with the locking elements (7) closed, these locking splice-clips (12) can be deflected. When load is applied against the insertion direction they become clawed in the pipe jacket.  This embodiment permits the shifting-in or closing of the locking elements (7) in a preassembly step and yet ensures a secure connection. The release of the connection through the radial shifting-out of the locking elements (7) is possible at any time.

Title: A method and apparatus for secure data communication
Inventor: GRUNNER OVE
IPC: H04L69/14
Filed: 1998-03-30
Abstract: A user system (2) recognises data as being either secure or general (non-secure). The data may be for performing on-line transaction processing or banking via the Internet. The user system (2) transmits the secure data from an ISDN circuit (6) on the D-channel, and the general data on the B-channel. The digital exchange (8) routes the general data via the Internet (12) to a service provider (3). A frame handler in the digital exchange (8) recognises the secure data in the D-channel and routes it via a physically separate telecommunications link (20) to the service provider (3). The alternative route (20) may include a management function connected by leased lines on each side to the exchange (8) and the service provider (3). The service provider (3) merges the secure and general data and performs the usual transaction processing operations.

IPC: B26D7/18
Filed: 1999-10-20
Abstract: Methods for setting-up a female blanking die for a die cutting machine for die cutting and/or blanking a carton blank, and universal press frames for use in such setting-up are all provided herein. The first stages in the erection of the female blanking die, which includes a rectangular framework of a front rail, a rear rail and two side rails, involve accurate placement of a template within the rectangular framework. All the rails are provided with a dovetail groove along its inside edges. This is achieved by the use of centre line orientation cylinders on a template, a centre line rod through aligned holes in the centre line orientation cylinders and centre line brackets at the precise centre point of the front and the rear rails. The template is mounted atop the centre line brackets by means of the centre line rod and rests loosely on template corner locking clamps. Then the template is secured to the accurately-placed template corner locking clamps in the rectangular frame, and is accurately-positioned and fixed there. The centre line cylinders are then removed and grid orientation cylinders are mounted on the template. A  plurality of grid support members are selectively-disposed along the internal perimeter of the rectangular framework by cooperation with the dovetail groove of the rails.  The grid comprising a plurality of intersecting rails, the pattern of the intersecting rails having a predefined shape, is disposed within slots within the grip support members and in the grid orientation cylinders and is locked into place in the grid support member. A  plurality of jogger members are provided which are selectively-disposed along the internal perimeter of the rectangular framework by means of cooperation with the dovetail groove of the rails, each jogger member having a particularly-recited structure.  The plurality of auxiliary adjustable support members may also be selectively-disposed along the internal perimeter of the rectangular framework by means of cooperation with the dovetail groove of the rails. The universal press frame is supported on four legs.  When the template is dropped below the universal press frame, and the legs are removed, the universal press frame becomes the female blanking die.

Title: Discontinuous transmission on high speed data channels
Inventor: MEYERS MARTIN HOWARD
IPC: H04W92/10
Filed: 1999-11-10
Abstract: The present invention is a method for efficiently utilizing spectrum resources belonging to a wireless communications system in the presence of data channels through a discontinuous data transmission technique: The discontinuous data transmission technique involves the transmission of a flag over a control channel (or some other communication channel) in frame f, wherein the flag would indicate to an intended recipient that a transmitter has a data frame to transmit to the recipient in some future frame f+q. In an embodiment, the transmitter would subsequently transmit the data frame over a data channel (or some other communication channel) in frame, f+q if the flag indicated that the data frame was ready to be transmitted. In another embodiment, the transmitter would not transmit the data frame unless the recipient has indicated (via another flag) that the recipient is ready to receive the frame of data from the transmitter.

Abstract: An automated home beer brewing machine (10) and method makes beer in a single vessel (16) under automatic control. The machine (10) and method allows making of wort for beer without requiring apparatus to be sanitized, without boiling the wort, without the use of a traditional water-filled fermentation lock, and without using a wort chiller or ice-packing of a brewing pot. The inventive single vessel automated brewing operation allows the user to load ingredients, conducts a grain-steeping if desired, and then automatically carries out the rest of the brewing process in a single vessel (16) until summoning the user days later to sugar-prime and bottle the bear. Thus, the user is required to provide much less time and labor than conventional home beer brewing, and the invention also frees the home-hobby brewer of much of the current are traditionally attached to home brewing.
