Patent CA-2120839-A1 (CA)
Inventor: PRIEST WALTER L
IPC: B29L22/00
Filed: 1994-04-08
Abstract: A two station machine forms a parison from a plastic resin and then stretch blowing into a hollow-molded product. The machine has a preform station for forming a parison and a blow mold station for stretching and inflating the parison into the hollow molded object and then ejecting the hollow-molded product from the machine. The preform station and the blow mold station are disposed at diametrically opposite locations on a circumference of a circle. A transfer portion has a transfer head rotatable about an axis extending through the center of the circle and having a pair of identical transfer stations located at diametrically opposite locations with respect to the axis. An indexer rotates the transfer head between two aligned positions in which one of the transfer stations is in registry with the preform station and the other transfer station is in registry with the blow mold station.     Each transfer station has at least one parison engaging and retaining neck mold for engaging the parison formed at the preform station and retaining the parison for transfer from the preform station to the blow mold station upon rotation of the transfer portion from one to other of the two positions.

Title: Speech communication apparatus
Inventor: UMEMOTO YUJI
IPC: H04M1/60
Filed: 1994-01-10
Abstract: A B S T R A C T   A speech communication apparatus comprises an echo canceler (30) for canceling an acoustic echo component input from a hands-free speech loudspeaker (13) to a microphone (14).  The echo canceler (30) comprises a volume control (36) for variably controlling the volume of a receiving speech signal, an amplitude limiter (35) for limiting the amplitude of an output signal from the volume control (36), an echo canceler (31, 32) for estimating a pseudo echo signal from an output from the amplitude limiter and subtracting the estimated pseudo echo signal from the transmitting speech signal input from the microphone (14), and a nonlinear filter (34) for processing an output from the echo canceler, thereby limiting the amplitude level of the receiving speech signal to a predetermined level or less.  Therefore, even if a receiving speech signal having a high receiving speech signal level is input to the echo can-celer, the received speech is not distorted, and an acoustic echo can always be sufficiently canceled by the echo canceler.

Filed: 1995-02-23
Abstract: A masonry system in which specially shaped brick are dry-stacked and subsequently bonded by pouring mortar or grout into apertures in the brick to flow through the stacked structure to surround the individual brick leaving the front and rear faces exposed. The brick have alignment projections extending from the bottom bed faces which register with alignment grooves in the top bed faces of adjacent brick to align the brick prior to bonding. The projections and grooves define a recess to admit mortar between adjacent brick faces. The brick also have recesses in the header faces to admit mortar between adjacent header faces. The front faces of the brick are contoured to create the appearance of mortar joints when the brick are stacked. The brick may be manufactured by extrusion, wire cutting and final shaping using suitable blades to achieve the desired finished shape. If desired, certain apertures through the brick may be covered over using a suitably shaped blade operating under appropriate conditions.

Title: Alloantigen enhancement assay
Inventor: POULETTY PHILIPPE
IPC: G01N33/569
Filed: 1993-10-07
Abstract: Methods and compositions are provided for the determination of cross-reactive alleles, where there is no antibody which will specifically distinguish between the two alleles. Particularly, the method employs an antibody which binds to the two alleles bound to a surface, an antibody specific for one of the alleles, a labeled conjugate which binds to a consensus sequence present in both alleles and positive and negative controls. By having an enhanced value where the interfering allele is present as compared to a value for the target allele, one can distinguish between the various alternatives involving the presence or absence of one or both alleles.

IPC: G06F3/03
Filed: 1995-05-26
Abstract: A positioning device intended for filling in forms with the aid of a computer program and comprising a base plate on which a sample of a form or the like can be separably affixed, and an X-Y coordinate carriage assembly including two coordinate members. The first member is a ruler parallel to the X-coordinate, and manually movable over the sample in the Y-coordinate direction along the second member, which represents a static guide element secured to the base plate. The ruler is provided with a slide manually moveable therealong, so as to be capable of coinciding with any point of the sample. The ruler and the slide are provided, respectively, with a first and a second coordinate optical units, which are adapted to register, and transmit to a computer interface, signals corresponding to the position of the slider with respect to its initial reference position at a corner of the sample. Both these coordinate optical units are linked to the computer interface via an electronic unit and a manually controlled switch intended to be activated by the user when the location of said slide is manually brought into coincidence with the desired position on the sample. The signals transmitted by the two coordinate optical units are then processed by the computer program for controlling a printer during filling in a form (a drawing, or the like) which is identical to the sample affixed on the base plate.

Title: Modular plug for high speed data transmission
Inventor: FREIRE VENEGAS IGNACIO
IPC: H01R13/658
Filed: 1995-12-04
Abstract: Shielded modular plug (15) for category 5 applications comprises a plug housing (13) and a wire holder (10). The wire holder comprises a housing (20) with wire receiving cavities (22) extending therethrough, and a base wall extension (35) extending from the housing to a front end (36). The wire holder is assembled to the cable by inserting straightened wire ends into the cavities (22) of the holder and pulling the holder tightly against the twisted pairs of the cable. The wire ends (6) can then be trimmed with the front end (36) acting as the reference. The wire holder and cable ends are then inserted into the cavity (48) of the plug housing until a fully inserted position where the plug contacts (18) are positioned above the wire ends (6), and can be depressed for piercing through the insulation to contact the inner conductors. Due to tightening of the wire holder against the twisted pairs, the length of straightened cable is as short as possible thereby reducing crosstalk interference and enabling higher data transmission speeds. Furthermore, tightening of the wire holder against the twisted pairs ensures that connections are made in a reliable manner with less sensitivity to variations in the assembly procedure.
