Patent CA-2123594-A1 (CA)
Inventor: BAUMGARTNER HANS
IPC: A01G23/095
Filed: 1992-09-18
Abstract: ABSTRACT         The invention relates to a self-propelling branch remover with the aid of which relatively large branches on trees,  but even whole trees,  can be gripped and capped.        For this purpose, either so-called felling saws have previously been used, which were attached to the front end of a hydraulic crane and gripped the trunk with claws and sawed it off using a pivotable capping saw. The other solution was that of a worker who was lifted in a lifting basket up to the relevant place and carried out the work there manually using a saw. In both cases, the sawn-off parts dropped down in an uncontrolled manner since even the felling saws did indeed hold the piece tight, but could not hold it in the original position since they could not be used to transmit a torque to the crane arm. The attachment was effected by means of two universal joints.        In the present case, this is prevented in that a connection between the felling saw unit and the machine frame is selected, which can absorb both bending forces and torques. For this purpose, the felling saw unit is attached  so as  to be  rotatable  and pivotable  in a controlled  manner  relative  to  a  torsion-resistant, jointless telescopic crane arm such that the entire work can be carried out by remote control from the driver's cab of the self-propelling branch remover. This avoids complex cordoning-off and safeguarding work.

Title: Multiple interacting dve algorithm
Inventor: ZIEGLER ELDON W JR
IPC: G06F17/00
Filed: 1992-09-15
Abstract: A digital virtual earth (DVE) cancellation system which receives a phenomena input signal via multiple sensors (1, 2, 3) re presenting residual phenomena to be canceled, and has adaptive filters (12, 24, 25) for each of the multiple sensor/actuator pairs, (1, 4, 2, 5, 3, 6) which generate the appropriate cancellation signal (19, 20, 21) for the associated actuator (4, 5, 6). The multiple interacting DVE (MIDVE) algorithm estimates the noise at each sensor (1, 2, 3) by subtracting out the combined effects of each actuator signal (19, 20, 21) from the residual signal (16, 17, 18) at that sensor (1, 2, 3). This estimated noise signal is used to con trol the adaptive filters (12, 24, 25) associated with the subject actuator (4, 5, 6). These filters (12, 24, 25) receive the estimated noise as input. They then produce the cancellation signals by filtering the estimated noise with the filter weights. These weights are adapted using the residual signal (16, 17, 18) and the estimated noise convolved with the system impulse responses.

Dans la présente invention le porte-papier de soie est muni de quatre côtés dont la partie vue de face est conçue spécialement pour permettre de faire entrer et sortir les papiers facilement. Compte tenu que l'objet sera porté à un des poignets de l'utilisateur et du matériel employé pour sa fabrication, un bracelet flexible et amovible a été placé sur la partie centrale arrière pour permettre à celui ou celle qui le portera, d'ajuster facilement à la grandeur désirée, pour la maintenir solidement en place. S'avère très efficace pour gagner du temps car le coiffeur n'aura plus à chercher une place dans le bac à bigoudis, ou sur la comptoir de service pour déposer tant bien que mal sa boîte de papiers, qui de plus ne sera pas vraiment à proximité de ses mains. Ça lui évitera de demander à la cliente de lui passer les papiers (ce qui ne fait pas très professionnel). Une mini-boîte à éponge fixée à l'arrière de la boîte papiers sert à mouiller le doigt de l'utilisateur pour éviter de porter le doigt de la chevelure à la bouche, est plus hygiénique. La boîte papiers contribue à donner un service plus rapide et surtout plus professionnellement, son utilité est incontestable dans le domaine de la coiffure et sa beauté peut satisfaire les plus exigeants. Ne nécessite pas un nouveau type de papier.
Patent CA-2142973-A1 (CA)
Title: A methodology for selecting superagonists, antagonists and superantagonists of hormones whose receptor complex includes gp 130
Inventor: SAVINO ROCCO
IPC: C07K19/00
Filed: 1994-06-23
Abstract: It has been found that the ligands of the group of cytokins similar to Interleukin 6 (IL-6), that is Oncostatin M (OSM), Leukemia Inhibitory Factor (LIF), Ciliary Neurotrophic Factor (CNTF) and Interleukin 11 (IL-11), induce formation of a receptor complex of which the membrane molecule gp 130 is a part. It is thus possible to formulate the hypothesis that two different surfaces of the protein (in this class of hormones), known as site 1 and site 2 bind to two different molecules: site 1 to the specific receptor and site 2 to gp 130. The invention allows the identification of these sites and the isolation of variants having, with respect to the wild hormone, a greater affinity for the specific receptor (superagonists and superantagonists) or affinity for gp 130 reduced or abolished (antagonists and superantagonists). The figure shows the construct pHen.DELTA. hIL-6 and the production of phasmidic particles that can be used to select agonists of Interleukin 6.

Patent CA-2146876-A1 (CA)
Inventor: ANDERSEN VERNER E
IPC: B32B7/02
Filed: 1993-10-11
Abstract: The present invention relates to a method for mutually bonding at least two moving continuous webs of material (1, 5) to form a laminate (12) which includes at least one puckered material layer. A first and a second material web (1, 5) are advanced at different speeds (V1, V2) to a web-bonding means (4) in which the webs are mutually bonded and the resultant laminate (12) is further advanced at the lower speed (V2). Because of the difference in speed between the two webs (1, 5), that web (1) which moves at the higher speed (V1) at the web-bonding moment is puckered while the other web (5) remains smooth. The invention also relates to an arrangement for mutually bonding two material webs (1, 5) in accordance with the method, and to an absorbent article (17) which includes a liquid-receiving outer layer (20) which contains at least one puckered, first li-quid-permeable layer (21) and at least one smooth, second liquid-permeable layer (22).
Patent CA-2147643-A1 (CA)
Inventor: MCDONOUGH JAMES M
IPC: F23Q2/16
Filed: 1993-10-22
Abstract: A selectively actuatable lighter device (10) is disclosed which includes a body defining reservoir (12) for containing a com-bustible gaseous medium such as butane, and having a valve (20) arranged to be selectively actuated between a normally closed position and an open position which permits the exit of the gaseous medium.  Such lighter (10) can selectively produce sparks at a location (19, 22) proximate to the gaseous medium exit to ignite the gaseous medium. Such lighter device (10) embodies a resi-liently releasable valve actuator (14) which normally prevents actuation of the valve (22). The valve actuator (14) includes an inter-fering portion (14A) which is selectively movable to a position out of interference with an interfering portion (12B) of the lighter body, so that the gaseous medium may be released and ignited by the sparks.  Once the valve actuator (14) is depressed and re-leased, it returns to its closed or latched position to prevent actuation of the valve to the open position. To "re-use" the lighter, the valve actuator (14) must again be moved to an unlatched position so that the valve (22) can be actuated for subsequent ignition of the gaseous medium.
