Title: Internal combustion engine and process for operation thereof
Inventor: MERRITT DAN
IPC: F02B75/12
Filed: 1994-06-23
Abstract: The internal combustion engine contains one or more pairs of the first and second cylinders (12, 14), by that the first cylinder (12) has a greater working volume than the second cylinder (14), as well as the corresponding first and second pistons (16, 18). The second piston (18) is provided with the driving rod (234) and divides the second cylinder (14) into the first volume (15a), containing the driving rod of the second piston, and the second volume (15b) between the two pistons. The first cylinder (12) is provided with an air inlet pipe (25) and an outlet pipe (27). Between the two pistons (16, 18), it is formed the combustion space, when the pistons are in the positions of the internal dead centre, the combustion space with that contains the second volume (15b). The transferal means (39, 128) provide for the gas flow possibility between the first volume (15a) and the combustion space to the compression stroke and just as the release mean (128) arrests the air and fuel mixture movement from the first volume into the second volume till the end of the compression stroke of the second piston (18). The injector (34) feeds the fuel into the first volume during the suction stroke of the second piston. The engine is also provided with a driving mean for setting in motion of the second piston (18), which includes a retention mean, retaining the second piston (18) in the internal dead centre position during one part of the working stroke of the first piston (16). It is also proposed a process for operation of such engine.Claims: 75Fig.: 26

Title: Acetabular cup positioning insert
Inventor: KASHUBA GLEN A
IPC: A61F2/30
Filed: 1992-01-08
Granted: 1995-04-13
Abstract: An acetabular cup for use as a prosthetic implant has an insert with a body including a central bore for receiving a positioning rod therein. A key element is formed on the bore and is adapted to align the positioning rod. The insert has a locating element formed on an outer surface of the body and also includes spring elements extending radially outwardly from the body. The acetabular cup has a generally hemispherical shell member coupled to the outer surface of the insert. The shell has an outer surface for engaging the acetabulum and an inner surface having a circumferential groove for receiving the spring elements. The spring elements may be deflected radially inwardly out of engagement with the groove for releasing the insert from the shell. The spring elements can be deflected by pushing a sleeve down the rod to make contact with and deflect the spring element. The shell has a plurality of apertures extending from its inner to its outer surface, which apertures are located in an asymmetrical pattern about the shell. The shell includes a recess on its open end for receiving the locating element on the insert to align the insert at a predetermined orientation with respect to the apertures in the shell. The engagement of the insert onto the shell and the engagement of the locating element in the recess aligns the key element on the central bore and, therefore, the positioning rod at a predetermined orientation with respect to the apertures in the shell.

Title: Modifying protein immunogenicity
Inventor: CARR FRANCIS JOSEPH
IPC: C07K14/315
Filed: 1999-12-08
Granted: 2004-09-23
Abstract: It is known that proteins, or parts of them, may be rendered non- or less immunogenic to humans or other species by identifying one or more potential T cell epitopes and eliminating them by amino acid modification. Conventionally, certain epitopes may be retained in a protein sequence if the peptides constituting such epitopes are present in endogenous human protein, since they would be recognised as "self". However, it has now been found that even self epitopes may give rise to immune reactions. The invention provides for their elimination, for example by recombinant DNA technology, to render them more useful for administration to humans, for example for therapeutic or diagnostic purposes.

Title: Line reeving system for earth drilling machine
Inventor: WILLIS CLYDE A
IPC: E21B19/02
Filed: 1988-08-25
Granted: 1990-03-08
Abstract: An earch drilling machine includes a crown block assembly (14 min ), a travelling block assembly (18 min ) and a drawworks (20). The drawworks includes a drum (22) which rotates about a drum axis (24). The drum axis is oriented at right angles to a fast line plane defined by a fast line sheave (FL) included in the crown block assembly. In this way, the fleet angle between the drum and the fast line sheave is kept substantially equal to zero. Various sheave arrangements are described which combine proper selection of sheave pitch diameter, sheave axis angle, and sheave placement to ensure that the fleet angle of all of the sections of line extending between the crown block assembly and the travelling block assembly are reeved with a fleet angle exactly equal to zero. In this way line wear is reduced and the height, weight and windage of the mast are all minimised.

Title: A method of and apparatus for packaging a beverage in a container
Inventor: JONES MICHAEL EDWARD
IPC: B65B31/04
Filed: 1992-10-07
Granted: 1994-05-26
Abstract: A method of and apparatus for packaging a beverage in a container 1 having a primary chamber and a relatively smaller secondary chamber which communicates with the primary chamber by way of a restricted orifice has the exterior of the container maintained at atmospheric pressure. The container such as a can 1 to be charged with beer is engaged within a filling head block 24 through nozzles 35 from which beer 9 is to flow into the can 1 from a bowl 8. Prior to filling the can 1 is pressurised through the head 24 with nitrogen gas to greater than atmospheric pressure and subsequently evacuated to atmospheric pressure by control of valves 32, 33. Such pressurisation and evacuation may be repeated sequentially to dilute the atmospheric oxygen content within the primary and secondary chambers of the can 1 where the oxygen has negligible effect on the beer which is to be sold in the can. A gas exchange conduit 40 extends between the bowl headspace 12 and the can 1. Conduit 40 has a port 41 of a gas control valve 55 which port 41 is closable by movement of lever 60. A beer flow valve 37/46 controls flow of beer 9 from the bowl through nozzles 35. During pressurisation of the can 1 with nitrogen gas the lever 60 is adjusted to maintain closed the port 41 of the gas flow valve and the beer flow valve 37/46 to ensure that high pressure gas in the can 1 cannot flow by way of the gas exchange conduit 40 into the bowl headspace 12 and again flow through the nozzles 35 into the beer 9 in the bowl 8. <IMAGE>
