Title: Apparatus for loading a line closing machine
Inventor: HUMPHREYS JOHN C
IPC: D05B23/00
Filed: 1990-05-03
Abstract: An apparatus for loading stocking pairs onto a line closing machine (10, 12) has a number of equi-angularly spaced transfer arms (18) each of which carries pairs of support fingers (28-34) on which a pair of stockings are supported at the open end of the stockings. The transfer arms (18) are mounted on a carousel (14) for rotation about a vertical axis successively through a loading station and one or more transfer stations (20) at which the stocking pairs are loaded onto one or more line closing machines where they are formed into pairs of tights. At the transfer station each transfer arm is extended radially outwardly of the carousel with the support fingers (28-34) positioned to enable engagement of a pair of supporting arms (16) of the line closing machine into the stockings. Once the supporting arms (16) are engaged, the support fingers are pivoted away from the supporting arms to leave the stockings engaged on the supporting arms. The stockings are then processed by the line closing machine.

Filed: 1991-05-01
Abstract: 19 SYSTEME D'ENREGISTREMENT OPTIQUE DE DONNEES SUR DISQUE, ET PROCEDES DE LECTURE ET ECRITURE CORRESPONDANTS L'invention concerne un système d'enregistrement de données sur disque optique. Les disques optiques actuels, lisibles avec des lasers de longueur d'onde visible (entre 0,5 et 0,8 microns) ont une densité de stockage en surface qui est au maximum de l'ordre de un bit de donnée par zone élémentaire de surface d'environ 1 micromètre carré. Au dessous, la diffraction ne permet pas de distinguer des zones voisines. L'invention propose un moyen pour augmenter considérablement les capacités de stockage : on inscrit dans une zone élémentaire (14) d'une couche (16) un bit d'information non pas sous forme d'un point d'absorbtion d'une lumière laser, mais sous forme d'un réseau diffractant ayant un pas déterminé. Plusieurs réseaux diffractants de pas différents les uns des autres peuvent être superposés au même point, permettant l'inscription en une même zone du disque de plusieurs bits d'informations. Les réseaux diffractants sont réalisés par une variation locale périodique de l'indice optique de la couche. Ils sont réalisés par un faisceau laser d'énergie élevée, dans un matériau dont l'indice peut varier en fonction de cette énergie. La lecture se fait par un laser (22) accordable en fréquence qui permet de détecter, pour différentes fréquences, la présence ou l'absence de réseaux diffractants. Figure 2

Title: Packet routing switch
Inventor: FRANK STEVEN J
IPC: H04L12/56
Filed: 1991-05-10
Abstract: A switch is provided for selectively routing digital information packets received from at least first and second external sources to at least first and second external destinations. At least one of the first sources generates an information packet including a datum (or a request therefor) and a corresponding descriptor. First and second routing interconnects have inputs for receiving packets from respective sources and outputs for transmitting packets to respective destinations. The interconnects are also coupled for transferring packets between one another. Directories within the interconnects store descriptors corresponding to data associated with the first destination, as well as requests routed from the other interconnect. A controller routes packets based on the correspondence, or lack thereof, between the descriptor in that packet and an entry signal allocated to corresponding directory.

Patent CA-2047715-A1 (CA)
Title: Sheet control apparatus and method for sheet stacker
Inventor: SENN MARVIN J
IPC: B65H31/32
Filed: 1991-01-03
Abstract: This invention solves the problem that when a temporary support is inserted across a stacker, that stacker may damage vertically falling sheets. In the invention, a vertically movable table (11) is located such that the conveyor propels the sheets falling downwardly to form a pile of sheets thereon. A fork unit (14) moves inwardly across the stacker as a temporary support during pile removal. A brake (48) and clutch (49) unit is connected to the pulleys. A sheet control includes pivoted fingers (20) aligned with the belts (24) and secured to a shaft. An actuating unit (35) pivots the shaft to move the fingers into engagement with said aligned belts on the downstream side of the pulleys. To reduce or eliminate sheet damage, a pneumatic control provides a conjoint control to actuate said brake and pivot the finger shaft for momentarily stopping sheet movement in synchronism with the actuation of the fork. Thus, no sheets will be in the area of the moving fork.

Title: Method and an apparatus for taking out a sample of an amniotic fluid
Inventor: SUNDBERG KARIN
IPC: A61B10/00
Filed: 1990-05-10
Abstract: A sample of amniotic fluid containing cells may be taken out from the amniotic cavity by penetrating the wall of the amniotic cavity by means of a  hollow needle (15) through which a volume of the amniotic fluid may be withdrawn. Outside the amniotic cavity the cells or part thereof are separated from the amniotic fluid which is immediately thereafter returned to the amniotic cavity.  This means that it is possible to withdraw a relatively large amount of cells without considerably reducing the total volume of the amniotic fluid present in the amniotic cavity. Therefore, it is possible to take out a sample at an early stage of the pregnancy period. The sample may, for example, be withdrawn by means of a sampling device comprising a one-way valve (16, 17) including a cell filter (17). The sampling device may further comprise a syringe with cylinder (10) and a piston (11) movably arranged therein. By moving the piston (11) through a suitable number of consecutive suction and pressure strokes a suitable amount of cell material is deposited on the cell filter (17). The filter (17) may be withdrawn from the sampling device and the cells may be cultured on the cell filter or the cells may be flushed from the filter by means of a culturing medium.

Title: Solid-state transducer based dynamic fluid sensing system
Inventor: MALCOLM ROBERT G
IPC: G01F1/20
Filed: 1990-08-01
Abstract: A dynamic fluid flow sensing system measures relative fluid velocity with respect to a reference member. The system includes a sensor housing (10) supported from the reference member such that the sensor housing is exposed to fluid flowing past the reference member. A solid-state pressure sensing transducer (30) is supported by the sensor housing for generating an electronic output signal in proportion to a sensed dynamic pressure of fluid flowing past the reference member. A central processing unit (40) receives the electronic output signal from the transducer and generates a processed electronic output signal in accordance with a stored control program. A display (48) receives the processed electronic output signal and displays a visual readout of desired fluid flow characteristics based on the processed electronic output signal.  The dynamic fluid flow sensing system can be used on marine vessels to indicate vessel speed or in confined fluid flow passages to indicate flow characteristics such as pressure, velocity and/or flow rate.
