Patent CA-2047551-C (CA)
Inventor: COX JIMMY L
IPC: F28D1/00
Filed: 1991-07-22
Granted: 1993-12-21
Abstract: ABSTRACT OF THE DISCLOSURE Using a series of identically sized, single row, single circuit refrigerant coil modules,  fin/tube refrigerant coils of different nominal air conditioning tonnages are constructed by arranging different numbers of the identically sized modules in accordion-pleated orientations, with each modular coil having the same depth in the direction of intended air flow across the coil. Compared to conventional "A" coils used on the indoor side of air conditioning circuits, these accordion-pleated modular coils are more compact in the air flow direction, provide more coil surface area, permit lower coil face velocities with higher fin density, and significantly reduce the overall coil manufacturing costs since only one size of coil slab needs to be fabricated and inventoried to later assemble refrigerant coils of widely varying nominal air conditioning tonnages.

Title: Vacuum transfer apparatus for rotary sheet-fed printing presses
Inventor: DEMOORE HOWARD WARREN
IPC: B65H29/06
Filed: 1991-12-11
Granted: 2000-10-24
Abstract: A vacuum assisted sheet transfer assembly to has an array of support bars 46 which guide the unprinted side of a freshly printed sheet S along a curved transfer path P. The support bars overlie the airflow inlet 44 of a manifold housing 16, with the support bars providing smooth surfaces for engaging and supporting the unprinted side of the sheet material as it is pulled along the transfer path while simultaneously limiting the flow of inlet air through elongated inlet apertures 52, 54. As air is drawn through the inlet apertures 52, 54, the unprinted side of the sheet is drawn into engagement with the support bars as it moves along the sheet transfer path. The sheet transfer assembly 10 eliminates the need for conventional skeleton wheels and the like. Marking, smearing and smudging are prevented since the printed side of the sheet S is not handled or contacted in any way as the sheet is conveyed along the transfer path p.

Title: Motion compensation predicting coding method and apparatus
Inventor: MURAKAMI TOKUMICHI
IPC: H04N19/102
Filed: 1992-04-10
Granted: 2000-06-20
Abstract: A motion compensation predicting coding apparatus includes a motion detector for comparing pixel data in an image signal with pixel data of the previous image signal to generate a motion vector. The motion vector is indicative of the displacement differences between the image signal and the previous image signal. The image signal may be organized into blocks of pixel data for a single field or for multiple fields when motion detection is performed on the image signal by the motion detector. A subtracter generates a prediction compensation error signal by subtracting the pixel data in the previous image signal from the pixel data of the image signal. A coder receives the prediction compensation error signal and generates an appropriate coded output. The apparatus may also include an adaptive blocking mechanism for receiving the prediction compensation error signal and organizing the data in the signal into blocks into one of several fashions as dictated by the motion vector.

Title: Hybrid protein c
Inventor: FOSTER DONALD C
IPC: C07K19/00
Filed: 1990-12-28
Granted: 2000-02-22
Abstract: Human protein C molecules are modified to provide increased resistance to inactivation by human plasma factors while retaining substantially the biological activity of human protein C. The modifications are generally to the heavy chain of protein C, which chain may be substituted with a protein C heavy chain of non-human origin, such as bovine, yielding a chimeric protein C molecule. The human protein C heavy chain may also be modified to be humanlike, in that at least one amino acid from a nonhuman sequence may be substituted for the corresponding residue(s) of the human sequence, thereby allowing the molecule to retain substantially human characteristics yet haying increased resistance to inactivation. AIso included are methods for producing the modified protein C molecules and pharmaceutical compositions thereof. The modified molecules; having an increased halflife in human plasma, are particularly useful for treating coagulationrelated disorders, such as protein C deficiency or thrombosis, or for promoting fibrinolysis in a patient.

Title: Adaptive motion compensation using a plurality of motion compensators
Inventor: KRAUSE EDWARD A
IPC: H04N7/26
Filed: 1992-10-05
Granted: 1998-04-07
Abstract: Digital video signals are adaptively compressed for communication to a receiver.  A plurality of block-matching motion compensators (30, 32), each using a different block size, compare current video image data to prior video image data.  Video image data output from the motion compensators is compressed (14, 18), and the compressed data from each motion compensator is compared (20) to find which motion compensator results in the least amount of compressed data for a region of a current video image corresponding to the smallest of the block sizes.  The compressed data having the lowest bit count is transmitted to a receiver for recovery of a motion vector.  The recovered motion vector is used to recover current video image data from the transmitted data and previously received video image data.

Title: Lift for watercraft
Inventor: BASTA SAMUEL T
IPC: B63C3/06
Filed: 1993-02-08
Granted: 1996-06-25
Abstract: Upwardly extending pivoting booms are supported on a rectangular base which is submerged in water.  Watercraft supports on mounting arms are connected to the pivoting booms.  A double-acting hydraulic cylinder attached between the rectangular base and pivoting booms swings the pivoting booms upwardly until they are braced by boom supports on the rectangular base at an angle over center.  This raising of the pivoting booms lifts the mounting arms and watercraft supports to remove a craft from the water and disposes the booms, mounting arms, and craft in a stable, secure over center configuration.  Actuation of the double-acting hydraulic cylinder in the opposite direction forces the booms back out of the over center position and lowers the craft into the water.

Abstract: Synthetic hair may be implanted using bundles of synthetic fibres joined at their lower end so that they will be firmly anchored in the scalp and not easily pulled out. The implants may be inserted by means of a tool which comprises a short sharp hollow tube and a manipulating handle. The tip of the tube may be inserted into the scalp to provide a conduit into which the synthetic fibres are sewn into the scalp.      The synthetic fibres are implanted by having curved needles at one end and a juncture of several fibres at the other end. The needles are inserted through the tube and into the scalp and out through the outer surface at various locations like normal hair, but because they are joined and anchored within the scalp, will not be easily removed.      Alternatively, the skin can be surgically lifted and the fibre inserted through the skin from underneath.

The inlet port is connected to a supply of a combustible mixture comprising fuel, lubricating oil and air.  During engine operation, the mixture flows through the crankcase, the duct, and the air intake passage to the cylinder.  Valves and valve actuating  mechanisms control the flow of the mixture to the cylinder and the flow of exhaust from the cylinder.  The oil in the mixture lubricates the engine parts in the crankcase, the valves and the valve actuating mechanisms.  The duct preferably forms a plenum or surge tank containing the mixture under pressure.  The engine may include more than one cylinder and piston, such as a two-cylinder engine having pistons which move in synchronism to produce crankcase compression.
