Title: Adjustable girth former
Inventor: KOVACS LLOYD
IPC: B65B9/06
Filed: 1993-10-29
Abstract: An adjustable girth control for a tube former (16) in a packaging machine (10) for encapsulating individual rolls (14) or groups of rolls (14) in a film (18). The tube former (16) includes a forming body (46) which is shaped to envelop the product (14) passing therethrough and which has opposite adjustable forming elements (48, 50) with a variable gap (52) between them.

Patent CA-2147906-A1 (CA)
Inventor: FOLADARE MARK JEFFREY
IPC: H04W84/02
Filed: 1995-04-26
Abstract: We have recognized that in the prior art, to insure that there is at least some communication between the calling and called parties, when the called party is unavailable to take a call, the calling party may be connected to an alternate destination, e.g., a voice messaging system, and the caller's telephone call is considered completed. If the called party thereafter becomes available, the called party is not connected to the caller's telephone call. However, in accordance with the principles of the invention, this problem is overcome by, in response to receipt of an indication that the called party is available for a caller's telephone call after the caller's telephone call has already been connected to an alternate destination, a) disconnecting the caller's telephone call from the alternate destination and, instead, b) connecting it the called party, thus interrupting the connection between the caller and the alternate destination. Optionally, a tone or announcement may be supplied to the caller to indicate that the called party will now be connected "live" to the caller.

Title: Method for manufacturing a high strength angioplasty balloon
Inventor: RADISCH HERBERT R JR
IPC: B29C61/08
Filed: 1995-05-26
Abstract: A method of manufacturing polymeric material having enhanced structural integrity includes heating the material to a temperature between the material's glass transition temperature and the material's melt temperature. Once heated, the material is highly overstretched in a first direction and moderately. overstretched in a second direction. The material is then held in the overstretched condition while it is allowed to cool to. room temperature.      Cooling is followed by reheating to a curing temperature.      After curing for a predetermined period, the material is again allowed to cool. The completed material has high polymeric orientation in the first direction and moderate polymeric orientation in the second direction. Therefore, the material is characterized by enhanced structural integrity and absence of pinhole defects common to highly oriented polymeric materials.

Title: Telephone exchange with voice mail device
Inventor: HEGEDUES ARPAD
IPC: H04M3/533
Filed: 1995-05-31
Abstract: Telephone exchange with speech store equipment which is connected to the calling subscriber after a predetermined time if the called subscriber does not answer the call, as well as method to store such voice messages in such an exchange, whereby the speech store equipment is able to store voice messages arriving from the calling subscriber and intended for the called subscriber and to send them to the called subscriber on his request.  The telephone exchange comprises switching means which will also connect all further calls for the called subscriber to the speech store equipment as soon as one switch-over after timeout of the called subscriber to the speech store equipment has been executed.  Hence, the exchange recognizes that the called subscriber is not ready to speak and switches all further arriving calls to the speech store equipment.

Title: Swimming pool cleaner with vibratory power
Inventor: RIEF DIETER J
IPC: E04H4/16
Filed: 1994-10-24
Abstract: A pool cleaner having an improved self-starting vibratory power source including a power-source chamber (24a) laterally defined by a pair of sealing walls (30f), a vibrator (30) which pivots in the chamber and has two wall-facing edges (30w) adjacent to the sealing walls and a pair of upstream flow-facing edges (30ue) positioned to be alternately reactive to fluid dynamic forces, and a seal (30d) along each wall-facing edge (30w) in sealing relationship with the sealing wall (30f) adjacent thereto and freely movable with respect to the sealing wall to accommodate passage of dirt and debris. Preferred embodiments include seals that have upstream arcuate surfaces (30us) which by virtue of wide notches (30i) in the vibrator, are substantially free of contact with the vibrator, and back edges (30h) substantially exposed to flow upstream of the vibrator, such that the seal is freely driven against the sealing wall by pressure differentials, freely self-adjusts to allow passageof dirt, and prevents accumulation of dirt.
Patent CA-2176055-A1 (CA)
Title: Device for intratracheal ventilation and intratracheal pulmonary ventilation including reverse venturi
Inventor: FISCHER FRANK J JR
IPC: A61M25/00
Filed: 1996-05-08
Abstract: A device (10, 80 or 120) for creating a sub-atmospheric pressure near the carina (12) of a human or veterinary patient (48) includes a channel (28) or perforation (92 or 132) for the passage of an oxygen-containing gas therethrough, the channel (28) or perforation (92 or 132) being open in a direction distal of the patient,  so as to establish a zone  (30,  94 or 142)  of sub-atmospheric pressure by reverse venturi effect during patient exhalation.  The sub-atmospheric pressure in the zone (30, 94 or 142) facilitates removal of carbon dioxide from the lungs (54) of the  patient  and  permits  intratracheal  and/or  intratracheal pulmonary ventilation to be performed at pressures less than those conventionally required for such ventilation.  The device (10, 80 or 120) of the present invention is also advantageous in obviating the risks inherent in prior reverse venturi devices, specifically, the possibility of detachment of a tubular member in those devices, and the possible complications of surgical recovery of the tubular member from the bronchi (52) or lungs (54) of the patient (48).  The device (10, 80 or 120) of the present invention achieves this latter advantage either by eliminating the tubular member of prior reverse venturi devices,  or by providing a shoulder (130) affirmatively preventing distal movement and loss of it.

Title: Method and apparatus for signal coupling at medium voltage in a power line carrier communications system
Inventor: ARMSTRONG DONALD STUART
IPC: H04B3/56
Filed: 1994-11-24
Abstract: An electricity supply network comprises a plurality of intermediate voltage switching and transformer substations (11-1 to 11-3,12-1 to 12-3) connected together by underground cables. Each cable (22A, 22B) comprises at least one inner conductor and an outer sheath which is connected to the substation housing (20A, 20B). A PLC communication system comprises a plurality of transducers (23A, 23B) coupled to the cables at the substations. Each transducer is located on the side of its cable remote from the sheath connection to the substation housing, whereby the transducer is coupled to both the sheath and the conductor(s) of the cable. We have found that signals are adequately coupled to the cable conductors despite the shielding effects of the sheath. (The prior art technique requires the end of the sheath to be isolated from the housing and earthed by an earthing strap connected to the end of the sheath which is brought back through the transducer to the housing to effectively decouple the sheath from the transducer).

Abstract: A micropump including two glass sheets (2, 8) with a machined silicon board (6) sealingly inserted therebetween. An inlet valve (12), a pumping chamber (50) and an outlet valve (28) are arranged between an inlet (10) and an outlet (4). A pump diaphragm (56) forming one wall of the pumping chamber comprises a thickened central portion (58) interacting with the upper sheet (8) to form an abutment restricting the suction movement of the diaphragm (50), and lower abutment elements (60) restricting the movement of the diaphragm when the fluid is discharged. A piezoelectric pad (72) engages the diaphragm by means of am intermediate part (84) to perform the pumping movement between upper and lower limits precisely defined by the abutments. A precisely defined and constant flow rate is thus achieved regardless of changes m the performance of the piezoelectric pad.
