Abstract: Procédé de démoulage d'une partie de soufflet (22) résiliente située dans un moule pour coulage par injection. Le procédé consiste à mouler par injection une partie de soufflet résiliente autour d'une broche centrale colinéaire (28) et d'une chandelle (38) de démoulage, entourées d'une empreinte (30) à plusieurs parties. La partie de soufflet (22) comporte deux extrémités ouvertes (44, 50) dont une (44) est sensiblement rigide et fermée par la chandelle (38) de démoulage qui la traverse. La deuxième extrémité ouverte (50) est résiliente. Pour le démoulage on ouvre l'empreinte (30) à plusieurs parties afin d'extraire la partie de soufflet (22) de la broche centrale (28) et on ouvre radialement vers l'extérieur la partie de soufflet (22) située sur la broche centrale. Le fait d'ouvrir la partie de soufflet en même temps qu'on pousse l'extrémité ouverte (44) sensiblement rigide de la partie de soufflet par la chandelle (38) de démoulage permet de faire sortir de la broche centrale (28) la partie résiliente (46) et l'extrémité ouverte résiliente (50). Dans la dernière étape du démoulage l'extrémité ouverte (44) sensiblement rigide de la partie de soufflet est éjectée de la chandelle (38) de démoulage.

Title: Railway track and sleeper and gap-covering element therefor
Inventor: UNBEHAUN OLAF
IPC: E01B3/00
Filed: 1997-02-17
Abstract: On a railway track comprising a ballast bed (10), sleepers (12) provided on the ballast bed and tracks (14) mounted on the sleepers, the sleepers are disposed closely adjoining one another but out of mutual contact, leaving a gap, the sleepers defining drainage channels (134) extending transversely to the longitudinal direction of the track for lateral water drainage. The gaps between the sleepers may be covered by covering elements (142) or the sleepers may overlap without touching one another. In this manner the track bed is substantially kept free of water, the positional stability of the track is increased, therefore reducing or rendering superfluous the normally required maintenance work such as tamping as well as cleaning and weed control.

Title: System and method for providing competing local exchange carriers unbundled access to subscriber access lines
Inventor: SYLVAIN DANY
IPC: H04Q11/04
Filed: 1998-10-26
Abstract: A telecommunication switching network is described in which one or more competing local exchange carriers are to be provided with unbundled access to customer premises equipment though subscriber access lines.  The customer premises equipment is comprised of user terminals and a customer premises equipment connector that can transmit and receive any combination of telephone, fax, modem, video, and data signals. A line interface module is connected to the customer premises equipment by means of subscriber lines for routing the signals originating with the customer premises equipment ("local access signals") to a competing local access service node, instead of the service node operated by the incumbent local exchange carrier.  A network interface module is provided to set up a call path through a generic connectivity network.  The generic connectivity network, which is comprised of a number of interconnected switching nodes, transmits the local access signals to and from the service node operated by the competing local exchange carrier.
Patent CA-2254324-A1 (CA)
Inventor: BARTOLO GABRIELE
IPC: H04L69/40
Filed: 1998-12-11
Abstract: A method of detecting the loss-of-signal (LOS) condition at the input of a transmission line interface when the input signal is coded. The input signal decoding includes an additional procedure allowing the detection of loss-of-signal condition. Since the pseudo-random sequence of the input signal transitions includes sequences of code violations, the additional procedure, over a certain threshold error rate, corresponding to a number of code violations in a unit of time, detects the loss-of-signal (LOS) condition.

Abstract: A system and method enables nontechnical personnel to provide information relating to vehicle damage information via a graphical user interface of a computer system. The information provided by the user includes damaged vehicle area information, crush depth of the damaged areas information, and vehicle component- by-component damage information. This information is utilized by a .DELTA.V determination module executing on a processor to, for example, obtain respective overall vehicle damage ratings for each vehicle of two vehicles involved in a collision. The overall damage rating is obtained by applying a set of rules, based on a uniform quantification of component-by-component damage, to the subject vehicles and an identical or sister test vehicle from one or more crash tests which provide damage information.
