Patent CA-2030303-C (CA)
Title: Hollow fiber bundle element
Inventor: PAN CHUEN YONG
IPC: B01J35/06
Filed: 1990-11-20
Granted: 1999-10-19
Abstract: A hollow fiber bundle element is provided comprising a bundle of microporous hollow fibers disposed in a cylindrical impermeable casing. with respect to each fiber, its wall is selected to provide a permeability in the microfiltration range (0.05 to 5 micrometers). The bundle forms two longitudinal passageways, being the lumina of the fibers and the other being the void space between the fibers. A first of these passageways is densely and uniformly packed with minute solid particles. No binder is used to fix the particles - they maintain their distribution in the passageway as a result of having been densely packed under pressure. The ends of the first passageway are sealed and the fiber wall pores are smaller than the particles, whereby the particles are immobilized therein. The hollow fiber module packed with minute adsorbent particles in the first passageway provides an adsorber. A fluid mixture comprising a carrier and an adsorbate is introduced into the second passageway. The adsorbate diffuses through the fiber walls and is collected by the adsorbent particles. By way of result, the particles used in this adsorber can be of much smaller size than those used in a conventional fixed bed column. The use of small adsorbent particles enhances adsorption rate, and availability of a separate longitudinal flow passageway reduces pressure drop across the adsorber. Alternatively, the hollow fiber module may be packed with minute catalyst particles to provide an effective catalytic reactor with improved mass transfer between the catalyst particles in the first passageway and surrounding fluid containing the reactants, in the second passageway.

Granted: 1996-05-28
Abstract: A harvesting attachment for a combine that includes a table or platform carrying an auger to convey a cut crop into the combine body for threshing.  The leading edge of the table carries a reciprocating knife to cut the crop.

Title: Animal headgate with an automatic locking mechanism
Inventor: PRIEFERT WILLIAM D
IPC: A61D3/00
Filed: 1992-03-17
Granted: 1994-05-31
Abstract: Abstract An animal headgate has a rectangular frame in which a pair of neck-engaging yokes is mounted for coordinated sliding move-ment between a fully open position and a fully closed position. A parallelogram linkage interconnects each yoke to an associated sleeve on the rectangular frame so that movement of the sleeve between an upper and a lower position will move the yokes between the fully open and the fully closed position, respectively.  An over-center spring arrangement urges the yokes from a neutral, open position toward the fully closed position.  A unidirectional locking mechanism associated with each of the posts permits the spring arrangements to close the yokes about the neck of an ani-mal but prevents unassisted opening of the yokes thereby restraining the animal.  A notched bar and associated catch mounted on the upper end portions of the yokes provide for auto-matic operation of the headgate,  The spring arrangements act to hold the notched bar in the catch at a preselected open position for the yokes.  Opening pressure on the yokes from the shoulders of an animal that has inserted its head through the yokes will release the notched bar and permit the spring arrangement to move the yokes to engage the neck of the animal.

Title: Construction element for limiting the fore part of a formwork
Inventor: BRECHBUEHLER FRITZ
IPC: E04G21/10
Filed: 1992-06-12
Granted: 1995-04-04
Abstract: The construction element for limiting a fore part of a formwork consists of a prefabricated element having a width which corresponds to the thickness of the con-struction work to be erected and a modular length. The element comprises openings  for being  able  to push through reinforcing irons, pipework or the like tubes. Because the element is foreseen to remain in the wall, it is produced preferably with a relatively fine concre-te in which a reinforcing mesh of synthetic material is enclosed, which extends also over the openings and pre-vents the outflow of concrete at the time of pouring the latter into the formwork.     Such a shuttering element allows a fast and precise limiting of the formwork in the case the construction work is not poured in one part or is needing recesses for a crane. It requires no cleaning off or pulling off wooden parts when the joining part is produced.

Abstract: Charges and balances assignable to a credit card account are controlled and monitored by assigning a purchase limit to the card. More specifically, when a card is used to pay for a telephone call on a telecommunication network, the validity of the card is verified in, for example, a network database and the card record is examined for the presence of a purchase limit. If the card has a purchase limit, the network database determines the type of purchase limit whichapplies and if the balance is positive. If the balance is not positive and the purchase limit applicable does not authorize the extension of credit, a denial response is sent from the network database to an appropriate local operator system which provides a denial indication to the caller. If the available balance is positive, the network database forwards the balance to the operator system. Based upon the balance returned in the reply from the database, the operator system sends a request to a rating processor to determine the length of time the callermay talk. If the rating database cannot ascertain the amount of time a caller can speak, for whatever reason, the call is denied. Thus, the balance is used to determine how long the caller can speak. At various predetermined intervals during the call and immediately after the call has been completed, the actual charges are calculated and forwarded to the network database. If during a call, the maximum duration is exhausted, the operator system will terminate the call, calculate the actual charges, and forward the charges to the network database. The network database decrements the balance with each intermediate update from the operator system. At the termination of a call, the network database adjusts the card holders balance a final time to maintain the purchase balance accuracy.
