Title: Transgenic pomaceous fruit with fire blight resistance
Inventor: ALDWINCKLE HERBERT S
IPC: C12N15/87
Filed: 1993-09-29
Abstract: The present invention relates to a method of conferring resistance against fire blight to pomaceous fruit scion or rootstock cultivars by transforming such cultivars with a gene which encodes for lytic proteins. Such transformation can be effected by bac-terial infection or propulsion of particles into cell interiors. Once transformation has taken place, the cultivar is regenerated to a transgenic pomaceous fruit tree. This technique is particularly useful in treating apple and pear cultivars.

Title: Method and apparatus for cutting of elastomeric materials
Inventor: BECKER MICHAEL LEE
IPC: B23D57/00
Filed: 1995-03-29
Abstract: A method and apparatus for cutting an elongated body of  elastomeric material includes a tensioned wire which is oscillated in a generally up and down motion while traversing through the elastomeric material.  The wire acts  as  a cutting blade and prepares  the  cut surface of the elastomeric material to improve splices. The wire  is  suspended between  a pair  of  pivotally mounted arms so that the wire oscillates as the arms are rocked by an eccentric mounted to a rotating shaft.  The cutter wire passes  through the body  of  elastomeric material at an angle  relative to the plane in which the body  of  elastomeric  material  lies.    The  body  of elastomeric  material  is  secured  in  place  by  clamp segments which conform themselves to the cross-sectional shape of the body  .   The cutter wire is  traversed through the elastomeric material on a cutter frame which is moved by a ball screw driven by a variable speed electric motor.

Patent CA-2146595-A1 (CA)
Title: Kabaab kit
Inventor: KHADEM FEREIDOUN F
IPC: A22C7/00
Filed: 1995-04-07
Abstract: Putting ground meat patties on a hot grill causes burned spots when they touch the overheated grill. These burned meats and fats are carcinogenic and also hard to remove.          Another way to barbecue ground meat - instead of meat patties - is by using skewers thus eliminating the need of a grill.          The meat is not on a barbecue rack but is held by skewers. This method prevents burned spots. The skewer inside the meat cannot get overheated and is cooled down by the meat juices.          To put the ground meat onto the skewers is not easy. A two-part mould (the new invention) is therefore used with specific spaces, to accommodate both skewers and meat, in preparation for horizontal barbecue cooking. The ground meat usually loosens from the skewers at both ends and falls into the barbecue. To avoid the loosening of the meat from the skewers, the mould is designed in such a way that both ends of the skewered meat are tapered. The tapered parts of the meat cook faster and stick to the skewer, thereby avoiding the loosening of the meat from the skewer.          To avoid the meat sticking to the mould, a thin celluloid-like film is used to cover the inside of the mould during the moulding process. After the mould is opened, the skewered meat can easily be taken out of the mould, and the cover film can then be: a. removed from the meat for immediate barbecuing or b. left on, if storage is necessary, to protect against dust, insects and also from drying out.

Patent CA-2175277-A1 (CA)
Inventor: MONTEITH JOSEPH G
IPC: E03F5/16
Filed: 1996-04-29
Abstract: A tank interceptor for rain water and waste-water includes a container divided by a partition into an upper by-pass compartment and a lower treatment compartment. An inlet and outlet for the container are located in the side wall adjacently above the partition. The partition defines a raised weir which constrains liquids entering at low flow rates to pass downwardly through an adjacent opening through the partition, to collect in the treatment compartment below the partition. A second opening through the partition is located adjacent the outlet, and pipes are associated with bothopenings. One of the openings is made large enough to allow passage of maintenance personnel, thus obviating the need for a further access opening and a liquid-tight seal for that further opening. An access opening at the top of the container is generally aligned with the large-diameter opening through the partition, thus allowing inspection, sampling and pumping out, without requiring maintenance personnel toenter the container.
