Title: Monoclonal antibody specific to ventricular myosin light chain1 and enzyme immunoassay for its detection in cardiac patients
Inventor: SIKORSKA HANNA
IPC: G01N33/68
Filed: 1990-05-31
Abstract: A competitive method of measuring human ventricular myosin light chain in cardiac patients which comprises incubating at least a monoclonal or polyclonal anti-HVLCS antibody, an enzyme, a VLCS antigen and an unknown amount of HVLCS analyte present in patient's serum. The anti-HVLCS antibody or the VLCS antigen, is directly or indirectly detected by means of enzyme-bound label, whereby the amount of HVLCS analyte, when initially present in patient's serum, is determined by comparing the extent to which the said VLCS antigen is bound to the said anti-HVLCS antibody with a calibration curve obtained from a known amount of said antigen. The anti-HVLCS antibody or the VLCS antigen is solid-phase bound. The anti-HVLCS monoclonal antibody has specificity to at least one of HVLC1 and HVLC2. There is prepared a monoclonal antibody which specifically binds to VLC1 and which is produced by the hybridoma cell line having the ATCC accession number HB 10471.

Abstract: There is shown a single, dual or multiple housing carrier unit for nets that may be used for playing games such as tennis, volleyball, and other net games that may be employed during physical education classes or physical therapy sessions.  The invention comprises a single or multiple elongate housings having opposing ends and a support strap extending away from the housings for connection to a pole standard or support stanchion.  Each housing has an internally and centrally located rotatable shaft with connections on the shaft for one  end of the net.  Each housing has a closeable opening extending longitudinally that allows a net to be dispensed and retrieved through the opening.  A handle on one end of the rotatable shaft enables a person to wind the net either into a tightened set-up position or a completely rolled up storage position.  Pins are provided that are held captive on the straps to engage the handles in a predetermined fixed position when so desired.  The invention also concerns a bracket that is designed to be attached to bleacher assemblies wherein the bracket has connections to a terminal end for connections for the other end of the net located away from the housing and a clamp member for attachment to a board slat forming a part of the bleacher assemblies when the assemblies are in a folded and stored position.     The invention also concerns a net antenna for net boundary markers to warn players that they are nearing the support stanchions during play.  The net antennas comprises a flexible body having opposing ends with one of the ends being centrallysplit so as to form two adjacent legs that can straddle a game net.  Co-operating elements of releasable fastener means extend through the net mesh and hold the antenna in position.    The invention also comprises a terninal end for adjustable connection to a support stanchion or bleacher bracket and connections for one end of the net.

Title: Image coding system
Inventor: MURAKAMI TOKUMICHI
IPC: H04N7/50
Filed: 1992-05-15
Abstract: An image coding system determines an amount a data that is output by a coder of the system and also determines a target code produced amount based on the motion of an input image.  The coder of the coding system encodes the input image.  A record of a data amount of past coded data is used as the inference of the target code amount.  Hence, proper coding can be performed in a sending side.  Further, by converting the data amount into a value with a condition to be standard, accuracy of the inference may be improved.  In addition, an indication of the power amount of the data to be coded is used as a factor for determining a target code produced amount to expedite a combination of a plurality of coding modes.
Patent CA-2069993-A1 (CA)
Inventor: OKANOUE KAZUHIRO
IPC: H04L25/02
Filed: 1992-05-29
Abstract: An adaptive sequence decoder comprises a maximum likelihood sequence estimator for deriving a decision sequence of a received signal in response to a control signal. Channel estimators of zero-th to m-th order of channel impulse response are connected to the MLSE to produce a first signal representing a respective order of a replica of a transmitted signal and a second signal representing a respective order of channel impulse response. The first signals from the channel estimators are summed to produce the replica of the transmitted signal for comparison with the received sequence to produce an error signal, and the second signals are summed to produce the control signal. At periodic intervals, the MLSE control signal is initialized and the zero-th order channel estimator is reset to the initialized control signal, and the other channel estimators are reset to respective initial values to prevent time dispersion.

The container 12 has a body member 14, a closed lower end member 16 and a cone-shaped open upper end member 18.  The mold 210 has a pair of upper clamping members 250,252 and a lower clamping member 272 which slide along a liner 228.  The upper clamping members 250,252 and a seal 262 for closing the container 12 act on the double seam 19 between the upper end member 18 and the body member 14, thus ensuring that the upper end member 18 and the double seam 19 do not deform during reshaping.  The seam 17 between the lower end member 16 and the body member 14 is gripped between the lower clamping member 272 and a support member 258.  During reshaping, compressed air is supplied to the interior of the container 12, causing it to expand outwardly while the clamping members move inwardly.            See figure 5

Title: Plate holder for an overground display
Inventor: GILES TREVOR P H
IPC: A47G1/16
Filed: 1992-08-04
Abstract: A plate holder for hanging a plate to a wall for display, comprising a spiderweb-like net and hooks to attach the plate to the net. The net is preferably made of peripheral threads positioned to form a plurality of concentric circles equally spaced and linked together with a set of radial threads positioned in pairs. The net is placed behind the plate and the hooks are positioned to simultaneously engage the plate lip and one of the concentric circles according to size of plate. For a better fitting, the hooks are provided with two snapping recesses, located at different positions on the hooks, for grabbing the net. For smaller plates, the external circles on the net can be cut off. The hooks are made of a material that is not likely to scratch the plates, such as nylon. The plate holder is then fixed to the display site, such as a wall, by a means, such as a conventional painting hook, grabbing one of the threads of the net. This plate holder provides a very reliable means for mounting a plate without damaging it. This plate holder also permits viewing identifications marks on the back of the plates without having to remove it and is adaptable to a multitude of plate sizes.

Filed: 1992-12-16
Abstract: The present invention is a time-constant detecting circuit incorporated in a LSI, for detection of the variations of component values of resistors and capacitors in the LSI as the variations of a time constant. A pseudo-resistor iscomposed of a switched-capacitor circuit. Two analog switches are switched on and off alternately in a period T to control charging and discharging of a capacitor. With the operation of the capacitor having a capacitance C, there is formed a pseudo-resistor of a resistance Rp = T/C. A predetermined DC voltage Vout is divided bya series circuit of the pseudo-resistor and an ordinary resistor, and is smoothed by a second capacitor. Output voltage Vout, smoothed and allowed to appear at the output terminal, is uniquely defined by a time constant  = 1/RC, so that the variations of the time constant formed with the resistors and capacitors in the LSI can be detected by a measurement of the output voltage Vout.
