Title: Clutch and brake arrangement switchable by a compressible fluid especially pneumatically
Inventor: PEDERSEN SVEND P
IPC: F16D69/00
Filed: 1991-02-27
Granted: 1995-04-18
Abstract: A clutch and brake device switchable by a compressible fluid, especially pneumatically, has an input shaft and an output shaft (5, 8) which are mounted in a housing (1) and terminate in a clutch chamber (17) in the housing (1).   A clutch flange (7), connected to the input shaft (5) so that the clutch flange and the input shaft rotate together, and a friction disc (12) are arranged in the clutch chamber (17).   The friction disc (12) divides the clutch chamber (17) into two working chambers (28, 29) pressurizable with different pressures and is arranged to engage the clutch flange (7) or an end face (49) of the clutch chamber (17) with a friction lining (15, 16) being inserted therebetween. To simplify and ensure that the working chambers  (28, 29) are sealed largely independently of an abrasion of the friction linings (15, 16), the face (47; 49) of the clutch flange (7) and/or of the clutch chamber (17) facing the friction surface of the relevant friction lining (15; 16) has an annular groove  (48; 50) concentric with the axis of rotation of the shaft.

Title: Look-ahead method and apparatus for predictive dialing using a neural network
Inventor: BIGUS JOSEPH PHILLIP
IPC: H04M1/27
Filed: 1991-10-31
Granted: 1996-07-23
Abstract: A predictive dialing system having a computer connected to a telephone switch stores a group of call records in its internal  storage.   Each call  record contains a group of input parameters, including the date, the time, and one or more workload factors.  Workload factors can indicate the number of pending calls, the number of available operators, the average idle time, the connection delay, the completion rate,  and the nuisance call rate,  among other things.   Ih the preferred embodiment, each call record also contains a dial action, which indicates whether a call was initiated or not.  These call records are analyzed by a neural network to determine a relationship between the input parameters and the dial action stored in each call record.  This analysis is done as part of the training process for the neural network.   After  this  relationship  is  determined,  the computer system sends a current group of input parameters to the  neural  network,  and,  based  on  the  analysis  of  the previous call records, the neural network determines whether a call should be initiated or not. The neural network bases its decision on the complex relationship it has learned from its training data -- perhaps several thousand call records spanning several days, months,  or even years.  The neural network is able to automatically adjust -- in a look ahead, proactive manner -- for slow and fast periods of the day, week, month, and year.

Title: Ventilating system for toilet bowl
Inventor: MILLETTE GILLES L
IPC: E03D9/04
Filed: 1992-06-12
Granted: 1995-08-29
Abstract: The  invention  consists of a  ventilating  system  and particularly a ventilating kit to be installed on a  conventional toilet  bowl at the rear of the toilet seat above  the  apertures used  to  anchor the toilet seat to the  toilet  bowl.   The  kit includes  a parapet-like housing having a peripheral wall  member adapted to be mounted over and in contact with the back apron  of the  toilet bowl and disposed to encircle both  apertures  verti-cally  extending therethrough.   A pair of hollow  T-shaped  cou-plings are adapted to be mounted below each of the apertures  for providing an air passageway from the housing through the  apertu-res and into a piping arrangement which projects into an adjacent wall of the toilet room wherein a suction device is  located.   A cover is fittingly mounted over the parapet-like housing and  has a  pending  lip facing the seat cover and  adjacent  thereto  for defining an air passageway extending between the rear of the bowl and  inside the housing.   Upon actuation of the suction  device, air is withdrawn from the bowl adjacent the seat cover, through the housing and the apertures located through the apron.  The air pathway  extends  through the couplings and  through  the  piping arrangement  for  projecting  the air through the  walls  of  the toilet  room.   One  of  the essential features  of  the  present invention consists of using the apertures conventionally provided through the apron at the rear of the toilet bowl.
