Patent CA-2020638-A1 (CA)
Inventor: BRANNAN JAMES R
IPC: H01M4/80
Filed: 1990-07-06
Abstract: The present invention resides in the discovery that a strip of reticulated foam which is semi-conductive can be continuously electroplated, utilizing a cathode roll which is positioned, in a first electroplating zone, outside of the electroplating bath. An anode is immersed in the electroplating bath. The strip of reticulated foam is first introduced into the electroplating bath and travels in the direction from the anode to the cathode roll prior to contacting the cathode roll. In this way, the strip achieves a partial plate at the anode which provides a current path between the anode and the cathode roll effective for sustaining the plating reaction in said first electroplating zone.

Title: Thiol-terminated hydroxyamides
Inventor: GROSS ANDREW W
IPC: C07C319/12
Filed: 1990-07-27
Abstract: Novel thiol-terminated hydroxyamides, and processes for their preparation and use are provided. These hydroxyamide compounds may be prepared by the reaction of a mercapto- functional alkyl ester, such as methylmercaptopropionate, with a molar excess of an alcohol-substituted amine, such as a .beta.-hydroxyalkyl amine. The thiol-terminated hydroxyamides are useful as polymerization chain transfer agents, particularly when it is desirable to form polymers or oligomers containing functional hydroxyamide end groups. By chain terminating such polymers or oligomers with reactive hydroxyamide end groups the polymers or oligomers can be further reacted with acid-containing monomers or polymers to form block or graft copolymers.

Title: Apparatus for bagging foodstuffs
Inventor: MUELLER ALAN C
IPC: B65B39/10
Filed: 1990-09-21
Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus for bagging foodstuffs such as potatoes includes a carousel having a number of hopper recesses defined in a top surface and an electric motor and transmission assembly for rotatably moving the carousel.  Each of the hoppers terminates in a chute for guiding the foodstuffs, and the carousel is vibrated in two separate directions in order to prevent the foodstuffs from becoming stuck.  An automatic bag gripping mechanism is provided beneath each of the chutes, and is adapted to close when a bag is placed into position between its grippers when the carousel is in a first position.  A control and interface unit continuously moves the carousel from the first position to a second loading position, and interfaces with a commercially available weighing machine to control the transfer of a load of foodstuffs from the weighing machine into one of the hoppers.  After loading, the carousel continues to move to a third position in which the bag gripping mechanism automatically opens to permit removal of the bagged foodstuffs.

Title: High speed system for reading and writing data from and into remote tags
Inventor: HENDRICK PETER L
IPC: G01S13/82
Filed: 1990-11-27
Abstract: The subject invention relates to a system for reading from and for writing data into electronic tags which may be associated with objects which are moving with respect to an interrogator, or may be located in fixed positions in the path of a moving interrogator. The interrogator, which is stationary if the tag is moving, sends a continuous RF signal to the remote tag. The tag backscatter-modulates the received RF signal with data temporarily or permanently stored in the tag, including, for example, data associated with the object to which the tag is attached, for example, its identity or contents.      The system of this invention uses a very efficient encoding technique for the data which is backscatter-modulated by the tag and received by the interrogator. The backscatter-modulated signals are made up of signals of first and second frequencies f1 and 2f1, respectively, where the second frequency 2f1 is twice the first frequency f1, and where one of the two binary bits ONE and ZERO is represented by one-half period of a signal of the first frequency followed by one period of the second frequency, and the other of the two binary bits is represented by one period of a signal of the second frequency followed by one-half period of a signal of the first frequency. The signals also contain FRAME MARKERS made up of five periods of frequency 2f1 followed by one-half period of frequency f1.      The WRITE-by-RF signals sent to the tag by the interrogator are made up of pulses of three different frequencies, one being frequency f2, the next 2f2 and the third 4f2. Either a ZERO or a ONE can be one period of pulses of either 2f1 or 4f2 with the other bit being the other frequency, and with the FRAME MARKER being one period of frequency f2. The MODE signal is four periods of frequency f2.

IPC: B29L1/00
Filed: 1990-12-17
Abstract: ABSTRACT OF THE DISCLOSURE          Multi-cavity injection molding apparatus to coinject pressurized melt from two or more melt sources.          An inner melt passage extends through the central bore of a melt distribution plate and an adjacent heated nozzle.          The nozzle has a tapered nose portion which extends into an adjacent heated cavity forming insert having a gate leading to one of the cavities.  An outer melt passage is separated by curved conduits on opposite faces of the melt distribution plate into four channels which are radially spaced around the central bore of the nozzle.  The four channels lead to a melt funnel duct which extends in the adjacent cavity forming insert around the nose portion of the nozzle.  Thus the melt from the outer melt passage is evenly distributed around the melt from the inner melt passage when they join just before entering the gate.

Abstract: A method for sealing a retort container comprises the steps of heat-sealing an opening of a retort container after charging contents into the container so that a line-seal having a width ranging from 0.5 to 2.5 mm is formed to thus seal the container and then performing knurled sealing at a portion including the line-seal. The sealing method can provide a container having sufficient seal strength and does not spoil the beautiful appearance of the flange portion of the container even if contents thereof remain in the flanged portion or the like. Moreover, the method does not cause foaming in the sealed regions at all and it is not necessary to perform the sealing treatment under substantially severe conditions to prevent the occurrence of the foaming and, therefore, the method can provide containers having a sealed portion easily peelable.
