Patent CA-2423439-A1 (CA)
Title: Mobile bearing knee prosthesis
Inventor: BROSNAHAN ROBERT
IPC: A61F2/38
Filed: 2001-09-26
Abstract: A mobile bearing knee prosthesis enables a surgeon to convert a mobile bearing insert having articular surfaces, supported by a tibial baseplate or tray from a rotating and translating prosthesis to one that rotates only. This conversion is accomphished with a fastener or locking member that connects through an opening in the insert to the tibial baseplate. This proximal can be used as part of a total knee surgery when the surgeon chooses to use a prosthesis that incorporates a movable articular surface. In one embodiment, a projecting portion extends proximally from the insert and cooperates with a cam on the femoral component. The projecting can be a post extending up from the proximal surface of the insert and the femoral component includes an intercondylar surface that may contact the post to constrain the relative motion between the femoral component and the insert. In another embodiment, the insert is a two part assembly that includes a larger member with a central opening and a smaller member that fits the opening.

Title: Novel process, construct and conjugate for producing multiple nucleic acid copies
Inventor: ENGELHARDT DEAN L
IPC: C07K17/10
Filed: 1995-01-12
Abstract: This invention provides inter olio an in vitro ,process for producing multiple specific nucleic acid copies in which the copies are produced under isostatic conditions, e.g., temperature, buffer and ionic strength, and independently of any requirement for introducing an intermediate structure for producing the copies. In other aspects, the invention provides in vitro processes for producing multiple specific nucleic acid copies in which the products are substantially free of any primer-coded sequences, such sequences having been substantially or all removed from the product to regenerate a primer binding site, thereby allowing new priming events to occur and multiple nucleic acid copies to be produced. This invention further provides a promoter-independent non-naturally occurring nucleic acid construct that produces a nucleic acid copy or copies without using or relying on any gene product that may be coded by the nucleic acid construct. Another aspect of this invention concerns a protein-nucleic acid construct in the form of a conjugate linked variously, e.g., covalent linkage, complementary nucleic acid base-pairing, nucleic acid binding proteins, or ligand receptor binding. Further disclosed in this invention is an in vivo process for producing a specific nucleic acid in which such a protein-nucleic acid construct conjugate is introduced into a cell. A still further aspect of the invention relates to a construct comprising a host promoter, second promoter and DNA sequence uniquely located on the construct. The host transcribes a sequence in the construct coding for a different RNA polymerase which after translation is capable of recognizing its cognate promoter and transcribing from a DNA sequence of interest in the construct with the cognate promoter oriented such that it does not promote transcription from the construct of the different RNA polymerase.

Abstract: A livestock sorter includes a weighing scale within a confining cage for obtaining a weight of the animal to be sorted depending on its reaching a predetermined market weight. Front and rear gates are each formed by two gate panels which are pivotal about a vertical axis at an outer edge of the gate panel. The gate panels are opened and closed by symmetrical levers and links connected from the gate panel to an actuating member slidable in a slide track along the midline of the container in response to an actuating force from a drive member. The actuating member, the links and the levers are arranged overcenter against an end stop of the guide track such that, with the gate panels in the closed position, force from the animal on the gate panels tending to open the gate panels provides no force through the links and the actuating member to the drive member.

Abstract: A liquid manure spreader is described which comprises a frame having a plurality of frame portions and having articulation means between each frame portion for permitting relative movement of each frame portion in response to directional changes of the liquid manure spreader. Such an arrangement facilitates turning of the liquid manure spreader. The liquid manure spreader also comprises two or more liquid manure tanks which are in fluid communication with each other. A pump may be used to re-circulate the liquid manure between the tanks, transfer the liquid manure to a spreader means, or both. Liquid manure can also be transferred between the tanks to thereby achieve a pre-determined weight distribution between the tanks. Such a fluid arrangement permits better weight distribution leading to better handling of the manure spreader.
