Title: Method and apparatus for fast determination of weights
Inventor: FEINLAND SEYMOUR
IPC: G01G19/00
Filed: 1992-09-17
Granted: 1996-06-18
Abstract: A scale for fast determination of weights including a platform and load cell transducer.  Output of the transducer is converted to a digital signal, processed by a low pass digital filter, and weights computed as a function of the sequence of digital signals by means of an algorithm which compares a first estimate of the weight to the break points of a postal rate chart and user the first estimate if it is not within a predetermined distance of a break point, and otherwise determines a second, more accurate estimate.  The platform and transducers are combined to form a structure which does not have any significant resonance below the cut off frequency of the filter.

Abstract: A method for wrapping a roll (1), particularly a paper roll, in a continuous wrapper web (2) of elastic material such as a paper web wrapper or plastic film, in which method the wrapper material web (2) is wrapped about the roll by rotating the roll (1), and further, in which method the wrapper material is tensioned by means of a braking arrangement (8) adapted to the essentially immediate vicinity of roll.      The invention is implemented so that the wrapper material web (2) is tensioned essentially during the entire time of its wrapping about the roll (1) to be wrapped and that, just prior to the braking arrangement (8) of the web (2) on the machine direction path, the wrapper material web (2) is slackened, in practice into a wave, (10), whereby the wrapper material web assumes a tensional equilibrium attitude (11) in the web cross direction and whereby the wrapping can take place in a slightly spiralling manner (13).

Granted: 2006-12-05
Abstract: A catheter (14) carries a functional component (16), like an ablating electrode, having a predetermined operating character-istic. The catheter (14) also electronically retains an identification code that uniquely identifies the predetermined characteristic. The catheter (14) is capable of transmitting the identification code to an external reader in response to a predetermined prompt. An associated apparatus, like an ablating energy source (12), reads the identification code and compares it to predetermined op-erating criteria. The apparatus (12) will not permit interaction with the functional catheter component (16) if the identification code indicates that the functional characteristics of the catheter (14) are not suited for the intended interaction. The catheter (14) can also store usage information to prevent reuse.

Title: Pressure based calibration correction of an ion mobility spectrometer
Inventor: JACKSON RONALD A
IPC: H01J49/00
Filed: 1996-06-19
Granted: 2007-05-29
Abstract: The calibration of an ion mobility spectrometer is corrected for the actual operating pressure and temperature conditions within the system. An absolute pressure transducer is used to monitor absolute atmospheric pressure. This information is used in conjunction with the measured calibrant drift time to pre-determine expected drift times of target ions, compensating for any pressure and/or temperature differences from the reference conditions under which the original calibration has been carried out. This improved calibration allows the unit to be operated with a significantly lower waiting period after start-up, and also under significantly different atmospheric pressure conditions. It also improves the precision of operation of the system.

Abstract: A fastener has a screw with an anchor located thereon, the anchor being spaced apart from the head. The anchor has a cut-away portion with a leading edge and a trailing edge of the cut-away portion angling downward. The leading edge angles downward a further distance than the trailing edge.  The anchor is spaced apart from the head by a distance corresponding to a thickness of a layer of material to be affixed to a support by an adjustable distance.  The layer of material has a small opening therein to accommodate the screw.  When the screw is inserted through the opening and into the support, the anchor turns through the opening, even though the opening is smaller than the anchor so that the material is located between the anchor and the head.  The screw can then be turned further into the support or further out of the support to adjust the distance between the material and the support in order to align the material as desired.
