Patent CA-2106582-C (CA)
Title: Element for sealing and monitoring a body, in particular a refuse dump
Inventor: RUTHROF KLAUS
IPC: E02D31/00
Filed: 1992-03-19
Granted: 1998-10-20
Abstract: The invention relates to an element for sealing and monitoring a body  (1).  Provision is made for two seals  (4, 5) to be spaced apart by supporting elements (6), while at least one channel (7) remains free between the supporting elements 16). At the outlet openings of said channel one or more sensors (18) is or are disposed. The seals  (4,  5) are connected to each other at their edges. The supporting elements (6) consist of a material which is permeable but resistant to flow, preferably a material  whose  flow  resistance  perpendicular  to  the channel  (7)  is less than that parallel to the channel (7). The position of a leak (29) can be determined with the aid of two sensors (18), which in a refuse dump also determine whether the leak (29) is located in the lower or upper seal (4, 5).

Abstract: An auxiliary baseband telephone instrument interface is provided in an answering machine to which any auxiliary telephone instrument, whether corded orcordless, can be connected and can control the answering machine functionality by use of in-band control signals. More specifically, a controllable switch arrangement is employed to connect outputs of an auxiliary instrument jack to outputs of a telephone line jack to which the answering machine is connected, or to the answering machine functionality itself and to disconnect the outputs of the auxiliary jack from the outputs of the telephone line jack or the answering machine functionality. Use of unidirectional paths controlled by a plurality of switching elements allows the user of an auxiliary telephone instrument connected to the auxiliary instrument jack to privately screen incoming calls on a telephone line connected to the telephone line jack, which the answering machine has answered and to controllably access other remote features of the answering machine. During the private screening of a call, a user of the auxiliary telephone instrument can interrupt the answering machine operations by entering an in-band control signal and thereby intercept the answered call. Additionally use of the controllable switch array enables a user of the auxiliary telephone instrument to answer incoming calls, if desired, or to make outgoing calls, if desired.

Title: Ultrasonic surgical instrument and methods for manufacturing
Inventor: ESTABROOK BRIAN K
IPC: A61B17/32
Filed: 1994-03-31
Granted: 1999-12-14
Abstract: The ultrasonic instrument includes a shaft (12) having an integral sheath (20) of PTFE encompassing the shaft and attached solely to the shaft. At the proximal end of the shaft, wrench flats (24, 26) arc exposed through openings in the sheath and grooves cooperate with complementary ribs (32, 34) on the sheath to prevent relative longitudinal and rotational displacement of the sheath and shaft. The sheath is in contact with the shaft at the nodes along the shaft. To manufacture the instrument, the sheath is initially formed to a diameter equal to or less than the diameter of the shaft and then mechanically expanded. Subsequently, the sheath is heat-shrunk about the shaft, and rolled continuously along the shaft, except at regions corresponding to the nodes along the shaft, to expand the sheath to a larger diameter to space the sheath from the shaft except at the nodes of the shaft.
