Filed: 1993-10-14
Abstract: "CROSS ARM PIN"                  Abstract of the Invention A cap fabricated of a nylon alloy or other suitable material is threaded onto one end of a metal cross arm pin.  External threads are provided around the cap to receive a porcelain insulator.  The cap is soft enough that the porcelain insulator will not be damaged when it is threaded onto the cap.  However, the cap is strong enough that the porcelain insulator cannot be pulled off of the metal cross arm pin by substantial tensional and/or torsional forces.

Title: Genetically modified wheat plants and progeny and method for production of hybrid wheat
Inventor: SMART GEOFFREY F
IPC: A01H5/10
Filed: 1993-01-18
Abstract: The invention concerns genetically modified wheat plants and the progeny arising these plants, and also a method of producing hybrid wheat using these plants. The genetically altered wheat utilizes homoeologous pairing to add a fertility restorer chromosome which contains telomeric chromatin which is homologous to another wheat chromosome which bears a recessive male sterility gene. The fertility restorer chromosome contains a major portion of alien chromatin from other wheat species, and also contains a male fertility restorer gene, and one or more marker genes. The genetic makeup of the wheat plant in one preferred form can be described as:  20'' + 4B(ms) + [4m (or 4th) - 4EL - 4BL]. These plants possess meiotic stability, and are used to produce hybrid wheat strains.

Title: Mask Protective Device
Inventor: FUJITA MINORU

Filed: 1995-07-25
Abstract: An opening end face of a frame is closed by a transparent thin film, a vent is formed in the frame, and a filter having a filtration area larger than the sectional area of the vent is mounted to the frame to cover the vent.  The filtration area of the filter an effective area where allows the passage of gas in the filter.  Then, the filter is mounted to the frame so that there is a certain space between the frame and the filter.  In the conventional device, since the filter is directly mounted to the frame without space between the filter and the frame, the filtration area of the filter is substantially the same as the sectional area of the vent.  In case of mounting the filter apart from the frame, however, the filtration area of the filter can be lager than the sectional area of the vent so that the quantity of gas flow is greater than that of the conventional one.  Therefore, its adaptability to the changes in atmospheric pressure and in temperature is also improved.
