Patent CA-2092377-A1 (CA)
Title: Packaging machine with thermal imprinter and method
Inventor: WEHRMANN RICK S
IPC: B41J15/06
Filed: 1993-03-24
Abstract: A thermal transfer printing apparatus for printing an elongate continuous web of items. The apparatus comprises a frame structure having an imprinter mounted thereon. A plurality of idlers supports the web of items and defines a path of travel for the web. A segment of the path of travel is adjacent the imprinter and its print head. A rockable arm is connected to the frame structure and contacts the web along a top surface of the web at two locations. A first of the locations is upstream of the print head and a second of the locations is downstream of the print head. The arm is connected to the frame structure about a pivot point and rocks about this pivot point during operation of the apparatus in a manner similar to a "teeter-totter." A stepper motor drives two drive rollers thereby advancing the web. When a selected item is in a proper printing position within the segment of the path of travel adjacent the imprinter, air cylinders actuate a nip and the print head against the drive rollers to maintain proper tension within the selected item. The rockable arm then rocks about its pivot point and the stepper motor drives the drive rollers to pull the selected item past the print head so that the item may be imprinted.

Patent CA-2109716-A1 (CA)
Title: A method of determining a load measurement value
Inventor: HOLM LAURI
IPC: G01G19/03
Filed: 1992-05-18
Abstract: A method of determining a load measurement value in dynamic weighing of an object passing over a weighing platform supported by load-sensing means generating a load-dependent weighing signal (S) which rises from basic level to a peak level, to subsequently fall to the basic level. An at least approximative signal peak value (Speak) is determined as representing the weighed load. The weighing signal is integrated at least during a time interval (t1-t5) about the point where the signal peak value is determined in order to produce a summation result, the time interval being recorded as a measurement time factor (M). Further, a form factor (F) for the weighing signal is calculated in the form of the ratio of the summation result, i.e. the integrated area under the weighing signal (S) for the time interval (t1-t5), to a corresponding rectangular area that would be obtained in static weighing, i.e. the product of a peak value and the above time interval.  Finally, the load measurement value is determined as the above signal peak value with a resolution depending on a quality factor Q =  F . M . k, wherein k is a factor chosen while taking into consideration the weighing conditions.

Title: Dual connections
Inventor: FERGUSON STEPHEN P
IPC: H04L69/40
Filed: 1993-11-30
Abstract: ABSTRACT                               DUAL CONNECTIONS   Data is protected in a data transmission system operating on the synchronous digital hierarchy. The data is transmitted in multiplex form between ports in the system and protection is applied between ports at different or the same aggregate bit rates. This protection is achieved by selecting between individual portions of the payload within the aggregate signals and each part of mutually protective portions has the same nominal traffic capacity. By duplexing an alternative signal path is created to ensure a continuity of traffic through the system in the event of a fault in one path.

Title: Hinge
Inventor: ROSSMO WILLIAM
IPC: E05D7/00
Filed: 1994-01-14
Abstract: An adjustable hinge has two plates connected by a series of knuckles, at least two on one plate and one on the other. The spacing between adjacent knuckles on one plate is greater than the length of the intervening knuckle on the other plate so that the knuckle may be moved along the hinge pin joining the knuckles. To effect this movement, the adjustable knuckle and the hinge pin are threaded. To provide adequate strength to the hinge, the pin and the non-adjustable hinge plate knuckles have two sets of axially facing support surfaces so as to distribute the hinge load over a sufficient area. Lateral loads on the threading may be limited through the use of cylindrical pin and knuckle sections.

Title: Intrauterine pressure catheter system
Inventor: DISABITO DAVID M
IPC: A61B5/03
Filed: 1994-02-15
Abstract: ABSTRACT           An intrauterine pressure catheter system for monitoring pressure in the uterus of a mother during labor and delivery.  The system includes a reusable junction box with a needle communicating directly to a pressure transducer sensor.  The sensor transmits changes in pressure to a conventional pressure monitor.  A connector attached to the catheter is pushed into the junction box and is held in place by a plastic latch. Inside this connector are an elastomeric plug and an adjacent diaphragm.  When the connector is installed in the junction box, the needle pierces the plug and the tip enters the air-filled volume between the plug and the diaphragm.  Fluid pressure in the catheter is communicated to the diaphragm surface and, in turn, passed to the air in the volume between the diaphragm and the plug.  Thus, the intrauterine pressure is transmitted directly to the sensor.  The system may be zeroed to atmosphere by simply removing the connector from the junction box.
