Patent CA-2146419-A1 (CA)
Inventor: KURODA KOICHI
IPC: D06F34/28
Filed: 1995-04-05
Abstract: A clothes drier according to the present invention can minimize failures in a sensor and can satisfactorily detect drying processing irrespective of the environment. In the clothes drier, an atmospheric temperature sensor 44L for detecting the substrate temperature required to determine the termination of the drying processing is disposed outside a circulating duct 18 and is mounted on a control substrate 42 having a thermal capacity on which a microcomputer for controlling operations performed by the clothes drier is mounted. Since the sensor 44L is provided outside the circulating duct 18, the sensor 44L is less affected by dust and water, as compared with a case where it is provided inside the circulating duct 18.      Consequently, it is possible to minimize defects caused by failures and aging of the atmospheric temperature sensor 44L. In addition, the temperature of the control substrate 42 having a large thermal capacity is detected, thereby to make it possible to satisfactorily determine the termination of the drying processing irrespective of the environment. Further, the sensor 44L and the microcomputer are disposed on the same control substrate, thereby to make it possible to reduce the length of a signal line as well as simplify wiring work (Fig. 2, Figs. 3A and 3B).

Title: Fast forward link power control in a code division multiple access system
Inventor: WHEATLEY CHARLES E III
IPC: H04J13/00
Filed: 1994-11-22
Abstract: The process of the present invention enables a communication link to have a higher data rate input signal while maintaining a constant data rate output signal. The method first convolutionally encodes the input data signal to produce a plurality of convolutionally encoded signals. Each of the convolutionally encoded signals are comprised of a plurality of data symbols. Each data symbol is repeated a predetermined number of times to produce a code repetition data sequence at a predetermined and fixed rate. The data sequence is then punctured such that symbols in predetermined locations of the data sequence are deleted thus generating a data sequence at a predetermined and fixed rate which is lower than that of the original data sequence. The encoded signals with the repeated data symbols are multiplexed to produce a data sequence.

Title: Method for processing customer payments
Inventor: NALWA VISHVJIT SINGH
IPC: G06K9/62
Filed: 1995-07-19
Abstract: A creditor provides a customer with a preprinted label, and instructions to attach the preprinted label to the negotiable instrument that the customer uses to pay the creditor. The label includes the customer's creditor account number encoded in machine-readable form. When the creditor receives the negotiable instrument with the attached label, the account number is automatically read using a scanner that reads the encoded information on the label. Using a preprinted label to put a long account number on the negotiable instrument, and automatically reading the account number, decreases the number of errors that occur when processing customer payments.

Title: Center beam golf club shaft
Inventor: GROVE DENNIS WILLIAM
IPC: A63B53/04
Filed: 1995-09-06
Abstract: The Center Beam Golf Shaft can be used in metal, graphite, compo-site or wooden shafts.     The typical modern golf shaft design is a hollow, tapered circular shaft approximately 30 inches to 40 inches long, depending which club the shaft is used for.  It is made of very thin material to give it strength and flexibility.  Because it is circular, the flexibility of the shaft is equal in all directions.     The Center Beam Golf Shaft has a metal beam, or a graphite beam, or a composite beam, depending on the shaft you are using the beam in.  The tapered beam is installed down the center of the tapered circular golf shaft, and is, depending on the type of material that it is made of, welded, soldered, glued, epoxyed etc. to make the beam and shaft one piece.     This new shaft has decided advantages over the other shaft in that the beam changes the degree of flexibility and the direction of the flexibility angle.  The flexibility angle will now be more horizontal compared to equal at all angles.  The horizontal flex gives the Center Beam Golf Shaft the ability to direct the golf ball in a straighter line.     The advantages to the golfer is enormous.  Golfing will become more accurate.  The metal shaft will have a metal beam inside. The graphite shaft will have a graphite beam. The composite shaft will have a composite beam.  This will make it easier to bond the pieces into a one-piece shaft.

Patent CA-2161567-A1 (CA)
Title: Micro-orifice nozzle
Inventor: WALDRUM JOHN E
IPC: B05B1/30
Filed: 1995-10-27
Abstract: A dispensing nozzle is provided with uniform, very-small diameter orifices of 0.001 to 0.015 inch (25 to 400 microns) by slotting at least one of two preferably- conical abutting faces between relatively movable parts defining a nozzle wall. The orifices can be formed by cutting with a broach to form an array of slots in a conical plug structure that fits against a complementary conical seat. Micro-orifices are defined between the conical structure and seat, preferably with an internal diameter of about 0.004 to 0.007 inch (100 to 170 microns) for dispensing uniform small droplets of thin oil/water invert emulsions. The conical structure can be liftable from the seat for flushing the slots by use of a spring mount, whereby increasing the dispensing pressure lifts the plug and flushes the slots. A filter screen reduces the tendency of the nozzle to clog. The dispensing nozzle provides an efficient and cost effective means to form uniform small droplets, enabling ultra low volume spraying of agricultural active agents in thin invert emulsions, for example obtaining effective applications at one pint to one quart per acre.

Patent CA-2173603-A1 (CA)
Inventor: GRIER LAURA ANN
IPC: C08G18/24
Filed: 1992-10-09
Abstract: Novel catalyst compositions comprising complexes of tin (IV) salts and amine compounds are used to prepare polyure-thanes, polyureas, polycarbodiimides and polyisocyanurates. The complexes, which preferably employ primary amines, allow de-lay of gelation until they dissociate under certain reaction conditions. The complexes can be prepared neat, or in situ in an active hydrogen containing formulation component. The complexes serve to delay gelation of the formulation because they are relative-ly stable to moisture and will predictably dissociate upon heating, either as a result of the exothermic nature of the reaction being catalyzed or with application of an external heat source. The catalyst compositions are particularly useful for preparation of car-pet underlay and in other applications requiring significant delay prior to gelation.

Abstract: A skid steer loader (10) is adaptable to be used with a hydraulically powered attachment. A hydraulic system (80) in the skid steer loader (10) includes a hydraulic circuit providing fluid under pressure. A first auxiliary control valve is coupled to the hydraulic circuit and is movable between a full open position and a full closed position, and is couplable to the attachment. An operator input device (108) provides a variable operator input signal. A controller (82) is coupled to the operator input device (108) and to the first auxiliary control valve. The controller (82) controls the first auxiliary control valve to move a portion of the way between the full open position and the full closed position based on the operator input signal. This provides smoother control over systems which merely operated the auxiliary control valve in a full open or full closed manner.

Title: Gamma ray densitometry in olefin polymerization reactors
Inventor: KANTZAS APOSTOLOS
IPC: B01J8/24
Filed: 1996-06-05
Abstract: The polymerization of olefins - especially ethylene or propylene - in fluidized bed gas phase reactors is an important commercial process. Such polymerization reactors are prone to fouling under adverse conditions. This fouling can be manifested in the form of large polyolefin "chunks" and/or polyolefin "skins" which adhere to the reactor internals. Under extreme conditions, the reactor must be shut down for cleaning. It is known to employ gamma ray sources/detector systems to monitor chink formation. This invention provides an improvement to such monitoring. In particular, this invention enables the use of an existing gamma ray source/detector system to measure and monitor the fluid bed density and the use of the measurements to control the fluid bed density.
