Patent CA-2036865-A1 (CA)
Inventor: LONG BRIAN J
IPC: H04L25/02
Filed: 1991-02-21
Abstract: ABSTRACT                 Interference Suppression System A line driver 12 is coupled by a pair of signal lines 10, 11 to a receiver 13.   Preprocessing circuitry 18,  for processing signals arriving on the pair of signal lines at the receiver, includes regulating means  (Fig. 2) for regulating the potential between the signal lines between predetermined limits and thereby modifying the sensitivity of the system to compensate for changes in line conditions and reject interference when the line driver is powered down.  The regulating means comprise: bias means Ql-Q3, Q12 for putting a bias on the signal passing through to the receiver, so as to hold the receiver input away prom the triggering voltage level so that it is not triggered by noise; and bias limiting means Q6-Q7, Q9-Q11 responsive to signals from the driver so as to limit or reduce the effective bias, so that the sensitivity of the system to true signals from the driver is not reduced below a desired level.

Patent CA-2041027-A1 (CA)
Inventor: FREDERICKSEN RAYMOND M
IPC: A43B13/20
Filed: 1991-04-23
Abstract: A shoe and shoe sole for accommodating forefoot strike activities such as aerobics, and forefoot strike tendencies of runners and the like, to forestall stress features, tendonitis and muscle tears, by incorporating a special forefoot pad in the midsole.  The pad has a forward chamber and a rearward chamber, separated by an internal wall with restricted orifices therein, the forward chamber being larger and extending curvilinearly beneath the five metatarsal heads of the foot, and the rearward chamber being smaller and extending behind the second, third and fourth metatarsal heads in the arch region of the foot. Impact compression by the metatarsal heads on the forward chamber causes controlled viscous liquid flow into the rearward chamber to absorb impact force, and such that the amount of liquid in the rearward chamber is temporarily greater than its at rest volume, causing the walls of that chamber to bulge and form a temporary arch support.  Release of force on the forward chamber results in the resilient flexible bulging walls of the rearward chamber forcing liquid back to the forward chamber.

Patent CA-2041822-A1 (CA)
Title: Envelope sealing device
Inventor: HIBBERD CHRISTOPHER V
IPC: B43M5/04
Filed: 1991-05-03
Abstract: An envelope sealing and feeding device has upper and lower interfitting parts defining a reservoir for a liquid to be used in the sealing operation and a substantially horizontal slot through which an envelope to be sealed can be fed. These parts co-operate with a wetter assembly which includes a wetter blade extending across the slot and a tubular structure containing wicking material and extending substantially vertically downwardly through the upper part and into the liquid reservoir.      With this arrangement, replacement of the wetter assembly is made easier. Assembly and dis-assembly of the relevant parts of the machine in order to obtain access to the interior of the liquid reservoir can be done without difficulty. The upper and lower parts can be joined together readily merely by using two bolts or screws, and once joined the wetter assembly can be added easily due to the simple structure, which allows easy preparation of the sub-assembly and then straightforward insertion of a tubular structure thereof in a slot in the upper part. In addition, attachment of the envelope sealer-feeder device onto a postage meter is made particularly easy by the use of a bracket.
Patent CA-2042182-A1 (CA)
Inventor: MAWHIRT JAMES A
IPC: B25J15/00
Filed: 1991-05-09
Abstract: The test tube holder includes an elongated tubular member which supports a pivot member and receives a removable adapter member.  The adapter member accommodates a test tube and can be interchanged with another adapter member that accommodates a different size test tube.          Biasing springs are provided in the adapter member to hold the test tube therein.  The biasing force of the biasing springs against the test tube is predetermined to permit easy insertion and removal of the test tube from the adapter member.  The test tube holder which includes the adapter member can be joined to other similar test tube holders in a manner which permits relative pivoting and tilting of one test tube holder with respect to another test tube holder.          The test tube holder further includes a detent arrangement for inseparably detenting the adapter member in the tubular member when a test tube is present in the tubular member. Removal of the test tube from the test tube holder enables the adapter member to be separated from the tubular member.

Abstract: Abstract of the Disclosure Device for Making Surgical Incisions With Combined Thermal and Ionizing Laser beams In the cutting with a laser beam there are in the target point material changes which affect the repeated  application  and  efficiency  of  the  laser beam.   Provisions are made to send a thermal laser beam and a photodisruptive laser beam and to combine the two  into one output beam having a common optical axis, in which the photodisruptive laser beam and the thermal  light  beam  travel  simultaneously.    The different laser types cause different effects in the target  point,   whereby  a  high  energy  output  is achieved at the target point to provide execution of incisions  in  fluid containing  substance.    Tissue ablation without bleeding of vascularized tissue is accomplished by the combined use of the argon and the Nd:YAG  laser  without  the  need of  a probe.    The simultaneous application of this dual laser utilizes the principle of the rise of pressure to the fourth power of the temperature increase : P = c.K4.
