Title: Apparatus and high speed process for making highly stretched film
Inventor: WOJCIK JOHN P
IPC: B29C55/06
Filed: 2000-09-14
Abstract: An apparatus and high speed process for heating and stretching a film having a bridle mechanism comprising a first heated roll and a second heated roll. The film is stretched as the film is transferred from the first heated roll to the second heated roll which rotates at a speed greater than the speed at which the first heated roll rotates. The film is fed into the bridle mechanism at a rate of about 1,500 fpm to about 2,500 fpm wherein it is stretched to a length that is up to about 450%  greater than its initial, pre-stretched length. The increased contact between the large diameter heated rolls and the film and the short draw gap between the two heated rolls result in a highly stretched film having minimal neck-in.

Title: Method and system for local wireless commerce
Inventor: WILLNER BARRY E
IPC: H04W8/20
Filed: 2000-11-24
Abstract: A system and method of conducting commercial activities such as an auction in a rather localized area (such as a shopping mall). Potential consumers located in the local area have a mobile wireless communications device (for example, a smart cellular phone or a 2-way radio or a Bluetooth communication device) including a set of stored instructions allowing the device to be programmed with a set of desired transactions and preferences such as the brands or transaction types which the consumer prefers. Merchants are connected to receive a communication from the communications device and respond to the desired transaction and preferences by proposing goods or services at specific terms such as price.  The mobile wireless communications device associated with the potential consumer has the potential to receive communications from merchants (either directly or through an intermediate system) and to transmit a communication back to the merchant indicating the potential offer so that a merchant can revise or improve the offer. In this way, local merchants can be aware of the offers that a consumer receives and can improve on those offers to secure the potential consumer's business. While the actual transaction may be conducted in person at the merchant, one can envision a system where the transaction is completed through the wireless communications system with the payment occurring through charge or other electronic transaction and the delivery of the goods or services through conventional delivery channels.

A high-pressure fluid source (24) and an abrasive particle source (26) are coupled to the nozzle (22) to generate an abrasive fluid jet (28) having a fluid and a plurality of abrasive particles for cutting a work-piece. The cutting machine (10) also has a particle removal device (40) including a tank (42) aligned with the nozzle (22), a settling container (46), and a fluid transport mechanism (44) to transport fluid from the tank (42) to the settling container (46). The tank (42) includes at least one compartment (56) configured to receive the fluid and the abrasive particles of the fluid jet (28) along at least a portion of the cutting path. Additionally, the compartment (56) is configured to control fluid flow within the compartment (56) so that the fluid jet suspends, and maintains the suspension, of at least a substantial portion of the abrasive particles in the one compartment without additional mechanical agitation. The fluid transport mechanism (44) can include a conduit with a first end in fluid communication with the compartment (56) and a second end outside of the compartment in fluid communication with the settling container (46). In operation, a portion of the fluid with suspended abrasive particles in the compartment (56) is transported through the conduit and into the settling container (46). The abrasive particles from the transported portion of fluid settle to a lower portion of the settling container (46) while a clarified fluid is removed from the settling container (46).

Patent CA-2331817-A1 (CA)
Inventor: GALL MARTIN
IPC: C07C29/149
Filed: 1999-05-10
Abstract: The invention relates to a method for producing hexanediol-1,6 from a carboxylic acid mixture containing adipic acid, 6-hydroxycaproic acid and small amounts of 1,4-cyclohexanediols, said mixture being obtained as a byproduct of the oxidation of cyclohexane to form cyclohexanon/cyclohexanol with oxygen or gases containing oxygen and through the water-extraction of the reaction mixture, by means of esterification of the acids and hydrogenation. The method comprises the following steps: a) converting the mono- and dicarboxylic acids contained in the aqueous dicarboxylic acid mixture to the corresponding carboxylic acid esters with a low-molecular alcohol; b) liberating the resulting esterification mixture from excess alcohol and lightboiling substances in a first distillation stage; c) separating the bottom product into an ester fraction which is essentially free of 1,4cyclohexanediols and a fraction containing at least the majority of the 1,4cyclohexanediols; d) hydrogenating the ester fraction which is essentially free of 1,4-cyclohexanediols with a catalyst; and e) extracting hexanediol-1,6 from the discharge from the hydrogenation using a method known per se, in a pure distillation step. According to the invention, an aqueous dicarboxylic acid containing more than 20 ppm cobalt and more than 40 ppm phosphorus is used in the form of phosphate and this aqueous dicarboxylic acid mixture is passed over a cation exchanger and after the esterification in accordance with step (a), over an anion exchanger.
