Patent CA-2251516-C (CA)
Inventor: FERLAND MARC
IPC: B23B45/00
Filed: 1998-11-04
Granted: 2001-04-24
Abstract: An improved machine for finishing or floating concrete that has been sprayed or blown onto walls or structures. A flat rotating surface is held against the concrete to be finished and a variable speed control is manipulated by the user to smooth and finish the work.      The handle of the invention extends radially on opposite sides of the power take off and lies within a plane normal to they axis between the motor and the rotating disk. This plane also passes through the center of gravity between the motor or power means and the rotating working surface. A variable speed control is disposed on the handle to allow the user to vary the revolutions of the float surface. The novel construction of the device allows the user to finish concrete surfaces more quickly and with less strain on shoulders and arms than is presently provided for with either manual floating or prior art tools.

Granted: 2010-06-01
Abstract: The invention relates to a method of preparing heteromultimeric polypeptides such as bispecific antibodies, bispecific immunoadhesins and antibody-immunoadhesin chimeras. The invention also relates to the heteromultimers prepared using the method. Generally, the method provides a multispecific antibody having a common light chain associated with each heteromeric polypeptide having an antibody binding domain. Additionally the method further involves introducing into the multispecific antibody a specific and complementary interaction at the interface of a first polypeptide and the interface of a second polypeptide, so as to promote heteromultimer formation and hinder homomultimer formation; and/or a free thiol-containing residue at the interface of a first polypeptide and a corresponding free thiol-containing residue in the interface of a second polypeptide, such that a non-naturally occurring disulfide bond is formed between the first and second polypeptide. The method allows for the enhanced formation of the desired heteromultimer relative to undesired heteromultimers and homomultimers.

Title: Cam path for orientating fingers of a harvesting reel
Inventor: COERS BRUCE ALAN
IPC: A01D57/03
Filed: 1999-11-09
Granted: 2003-01-21
Abstract: A pickup reel for a harvesting platform including a reel support structure with a reel shaft rotatably supported thereon. A plurality of radially extending arms are mounted to the reel shaft and a plurality of transverse rockshafts are mounted to the radially extending arms and are axially offset and parallel to the reel shaft and span the width of the platform. Radial fingers are mounted on each rockshaft. A cam is mounted to the support structure adjacent one or both ends of the rockshafts and defines an endless cam path about the reel shaft. A crank arm attached to each rockshaft carries a cam follower that engages the cam path for following along the path. The cam path is configured to cause the crank arms, and thus the rockshafts, to rotate about the respective rockshaft axis to vary the attitude of the fingers relative to the ground as the cam followers move along the cam path. The cam is segmented, having two or more cam segments joined together to form the endless cam path. The cam segments are joined together by removable fasteners to enable one segment to be removed and replaced to either vary the cam path or to replace a worn cam segment.

Abstract: Rubber plugs, which are to be used with medical containers or medical devices, are produced by forming a vulcanizable, mixed rubber compound, vulcanizing a resultant formed rubber compound, treating the rubber plug with steam of high temperature and high pressure, treating the rubber plugs in an aqueous solution which has been adjusted to be acidic, rinsing the rubber plugs with high-quality water, washing the rubber plugs with a shower of dust- and germ-free water, and drying the rubber plugs by at least one of far infrared radiation and high frequency heating. The process makes it possible to reduce the number of insoluble fine particles, which are attracted on a surface of each rubber plug, to an extremely low level and moreover, remove (or deactivate) pyrogen substances on and in the vicinity of the surface of the rubber plug.

Abstract: Arrangement 1 for washing and dewatering a fibre pulp suspension, which arrangement comprises two hollow, circular-cylindrical screen members 2a, 2b delimited by envelope surface and end walls. The screen members rotate towards each other to form a nip 10, at least one of the said screen members 2a, 2b being arranged in a vat 6 which partially encloses the envelope of the screen member and which, in the direction of rotation of the screen member, converges towards the envelope of the screen member. The invention relates to a sealing arrangement 8 at the end wall of the screen member. By retracting the seal a distance X from the envelope surface of the screen member in a limited area .alpha. near the nip 10, the seal is relieved of the very high hydraulic and mechanical pressures which occur in the nip. Wear between the end wall of the drum and the seal at the press nip is reduced. A simple pressurized seal can thus be used with the same low pressure applied along the entire circumference.

Abstract: A clock generating circuit generates a clock of a rate corresponding to a Dch rate in response to a specification from the exterior. A counting circuit detects completion of reception of one frame by counting the clock number up to "11" at timing at which a start bit detecting circuit detects a start bit in a serial signal. An S/P converting circuit fetches a serial Dch signal bit by bit in synchronism with the clock, outputs the latest fetched 10 bits in a parallel form and latches eight bits of a real data portion among the output data into a latch circuit at the time when reception of one frame is completed. In parallel with the above operation, a parity calculating circuit and flag/interruption generating circuit set various flags and generate a reception completion interruption.

Title: Engine head cover structure
Inventor: RYU YASUTAKE
IPC: F02F1/00
Filed: 2001-10-29
Granted: 2004-11-30
Abstract: An engine head cover structure has a head cover joined to the upper end of a cylinder head so as to define a valve operation chamber therebetween. The head cover includes therein an oil recovery chamber to which oil resided in the valve operation chamber is recovered by suction and a breather chamber that removes blowby gas from the valve operation chamber being provided in the head cover. The breather chamber is defined between a partition plate mounted on an inner wall of the head cover via clips and a surface of the roof of the head cover, and the oil recovery chamber is defined between the partition plate and a partition body welded thereto. It is thus possible to form the oil recovery chamber and the breather chamber without splitting the roof of the head cover, thereby making inspection of the joint for oil tightness unnecessary.
