Patent CA-2162197-C (CA)
Title: Communication system for programmable devices
Inventor: ANDERSON JEFFREY
IPC: G11C16/10
Filed: 1995-11-06
Granted: 2000-10-17
Abstract: An interface system for communicating between a programmable device, such as a hearing assisting device, and a programmer unit employs a circular shift register and a memory.  Upon initialization the memory contents are loaded in the circular shift register and cycled through so that each bit is exposed to the programmer unit for verification or change.  After a complete cycle through the shift register the program is fed back to the memory where it is used to control the transfer function of the hearing assisting device.  By use of this circular shift register only two connections to the programmer unit are required, thereby minimizing the mechanical size of the connector needed to connect the programmer unit to the hearing assisting device, which may be an in the ear device.  A low voltage version of the interface system uses current sources and a high voltage version of the interface system, such as used for a remote controller, uses impedances and a voltage source.

Granted: 2000-05-30
Abstract: A papermaking screen of the invention is formed of a first annular supporting member having a first annular recess formed at one side, and a second annular supporting member having a second annular recess  at  one  side.    The  second  annular  recess  has  a  size corresponding to that of the first annular recess and orients toward the first annular recess.  A plurality of space holding members is fixed to the first and second annular supporting members to establish a predetermined distance therebetween.  Also, a plurality of elongated members is situated in the first and second annular recesses and arranged parallel to each other between the first and second annular supporting members.  At least one of two elongated members situated adjacent to each other has a space forming device thereon relative to the other of the two elongated members.  When the elongated members are arranged parallel to and contacted to each other, a space is formed between the elongated members situated adjacent to each other. The elongated members can be easily disposed between the first and second annular supporting members.

Title: Method for reproducing conifers by somatic embryogenesis using mixed growth hormones for embryo culture
Inventor: PULLMAN GERALD S
IPC: A01H4/00
Filed: 1993-08-18
Granted: 2000-10-24
Abstract: The invention is a method for reproducing conniferous trees by somatic embryogenesis using plant tissue culture techniques in a multistage culturing process. A suitable explant, typically the fertilized embryo excised from an immature seed, is first cultured on a medium that induces multiple early stage proembryos. These are multiplied in a second culture having reduced growth hormones. The early stage embryos may then be placed in or on a late stage proembroyo development culture in order to develop very robust late stage proembryos having at least 100 cells. Culturing from this point continues in a cotyledonary embryo development medium containing an active gibberellin (GA) in an amount up to about 50 mg/L. Preferably exogenous abscisic acid (ABA) is also present in a similar amount. Concentration of GA and ABA may be reduced over time by inclusion of an adsorbent such as activated charcoal or by stepwise subcultures in which the later cultures have reduced hormone concentrations. After several weeks somatic embryos having the appearance of zygotic embryos will have formed. These may be germinated before or after storage and transplanted to soil for further growth. In addition to its use in the cotyledonary embryo development stage, GA may also be advantageously included in any of the maintenance cultures following embryo initiation. The use of GA results in larger and more robust somatic embryos and ultimately in greater germination success.

Abstract: A process for removing creases from a film eliminates a problem in the quality of the heat seal for a patch bag having at least a segment of one or more bag side edges (or the bag bottom edge)covered by one or more patches. The film creases are removed by inflating the film tubing which is later converted to a bag, heating regions containing the creases with a heating means to a temperature which, in combination with the pressure within the inflated tubing, causes the creases to relax. The heated crease-containing regions are then cooled and the inflated tubing is deflated and wound up in a new configuration in which at least one patch covers at least one side edge or the bottom edge.
