Inventor: ALESIO THOMAS
IPC: H04M1/675
Filed: 1993-08-17
Abstract: Encumbrances on making calls charged to a card can be reduced by a) storing information so that an association is created relating a card number and at least one calling telephone station, from which card calls charged to the associated card are to be made, b) using the association to retrieve the card number at the time a card call is made from the at least one associated telephone station and c) automatically supplying the retrieved card number to the telephone network at the appropriate part of call set-up, so that the card number need not be entered by the calling party. The association between the card number and the telephone station, which may be referred to as a "logical link", is 1) independent of any pre-existing relationship between the card number, or any subset thereof, and the telephone number of the telephone station and 2) continues to exist despite the going on hook of the calling telephone station. In accordance with an aspect of the invention,personal identification information, such as the PIN assigned to the card number by the card issuer or a specially assigned PIN for use with the invention, may also be related to the calling telephone station and the card number by storing additional information to create an association among the calling telephone station, card number and PIN.

Title: Method and apparatus for making a fibrous product
Inventor: NIEMINEN JORMA
IPC: B27N3/12
Filed: 1993-05-26
Abstract: In a method for making a fibrous product from vegetable-based cellulosic fibers, an air flow (A) is used for forming a mat on an advancing forming platform (1). The mat is bonded by means of thermally bondable binder fibers, such as thermoplastic fibers intertwined with the cellulosic fibers such that, upon being brought to a binding state through the action of heat, said binder fibers bond the cellulosic fibers to each other in the mat. The thermally bondable binder fibers intertwined with cellulosic fibers are subjected to the action of heat already in air flow (A) carrying the fibers onto forming platform (1) by setting temperature of the air flow sufficiently high.

IPC: E21D9/10
Filed: 1992-09-22
Abstract: A mobile mining machine (10) has a wheel-like cutterhead assembly (12) supported by a pitch boom assembly (20). A swing boom assembly (24) supports the pitch boom assembly (20). In one embodiment the swing boom assembly (24) has a pivot axis that is tilted from vertical and swings the cutterhead (12) and the pitch boom (28). A gripper assembly (120) having a floor gripper shoe (134) and a roof gripper shoe (132) brace the mobile mining machine. Thrust is provided by thrust cylinders (164) located between the gripper shoes (132, 134) and the main beam (26). Extension of the thrust cylinders (164) moves the cutterhead assembly (12), main beam (26), and rear portion of the mobile mining machine (10) forward relative to the gripper assembly (120) due to slidable engagement of the main beam (26) and gripper assembly (120). During re-gripping, the gripper cylinders (124, 126) and thrust cylinders (164) are retracted, causing forward movement of the gripper assembly (120) with respect to the main beam (26) and rear portion of the machine (10).

Patent CA-2125207-A1 (CA)
Inventor: MARTIN ANDRE
IPC: B61L23/00
Filed: 1994-06-06
Abstract: The link permits communications between cars of a railway or subway trains.   On at least a first one of the cars,    a   multiplexer   multiplexes   digital   signals representative of the status of various systems on the car, and processes them into a first digital trainline signal.  A transmitter includes a modulator which converts the digital trainline  signal  to  a RF  signal,  and the RF  signal  is transmitted,  by an antenna,  through free  space from the first car to a second car.   The second car includes an antenna for receiving the RF signal, and a receiver for de-modulating the signal and converting it to a second digital trainline signal.  A demultiplexer demultiplexes the second digital trainline signal into appropriate formats readable by the train systems on board the second car.   Both the first   and   second   cars   include multiplexers   and demultiplexers,  and  transmitters  and  receivers,  so  that communication is possible between the first car and the second car as well as between the second car and the first car.
