Title: Water-dispersible lipidic hop extract composition
Inventor: SCHULZE MARK H
IPC: C11B9/00
Filed: 1995-09-13
Abstract: The composition consists essentially of hop aroma and flavour components and comprises at least 10% by weight of free fatty acid substances derived from hops. It is produced by admixing a hop extract with either excess alkali or a lipase and then removing any aqueous phase.The starting extract, obtained by extraction with organic solvent or super critical CO2, may have alpha, isoalpha and beta hop acids removed. Heat, high shear or a co-solvent may be used to improve mixing of the lipidic organic phase with the alkali. The solubilised extract imparts an enhanced hop aroma and flavour upon addition to the wort between boiling and the beginning of fermentation. A beer incorporating the extract has a stronger hop aroma and flavour than beer incorporating the usual unsolubilised extract.

Patent GB-2302351-A (GB)
Title: Shifting tool,releasing mechanism,position feedback method and method of releasing
Inventor: GOMEZ ALFREDO
IPC: E21B47/09
Filed: 1996-03-05
Abstract: A shifting tool (20, 22, 24) is disclosed which allows movement of a shifting sleeve (12), to be followed by an additional force applied to ensure complete stroking of the shifting sleeve. This is accomplished by a shifting key (38) to normally shift the shifting sleeve, followed by an overpull key (32) which engages while the shifting key is still engaged. Once a predetermined force has been applied to the overpull key, the force applied from the surface is removed so that the tool may disengage from the sleeve. Subsequent manipulation, without necessarily any removal from the wellbore, if it does not result in a reengagement, provides feedback that the shifting sleeve has, in fact, shifted its full stroke. An emergency release is available which actuated by an overpull force beyond a predetermined level, is applied while the overpull key is engaged for an emergency release from the shifting sleeve.

Title: A differential mechanism
Inventor: YOUNG ALASTAIR JOHN
IPC: F16H48/00
Filed: 1997-03-06
Abstract: A differential mechanism has two output cam members (16, 17) rotatable about an axis X-X, each output cam member having a single frustoconical cam surface (22, 23) of undulating form comprising pairs of mutually inclined surfaces (24, 25:26, 27). Cam followers (28) having end surfaces (29, 30:32, 33) which engage the cam surfaces (22, 23) of the output cam members, so that relative rotation of said output cam members (16, 17) causes the cam followers (28) to slide axially. An input member (11) slidably supports the followers (28) and moves the followers circumferentially relative to the output cam members (22, 23). A first friction surface (16c) is operatively associated with at least one output cam member (16, 17) and inclined at an acute angle W to a plane normal to the axis of rotation X-X of the output cam members. A second similarly inclined friction surface (13c) is operatively associated with the input member (11, 13, 14). The first and second friction surfaces (16c, 13c) frictionally engage each other and generate a frictional torque FT which modifies the ratio of the torque output from the output cam members (16, 17) when relative rotation occurs between the output cam members.

Title: Method for manufacturing capacitor lower electrode
Inventor: SZE JHY-JYI
IPC: H01L27/108
Filed: 1998-05-07
Abstract: A method for forming the lower electrode of a DRAM stacked capacitor comprising the steps of forming a first dielectric layer 34, a silicon nitride layer 35 and an oxide layer 36 over a substrate 30. Then, a first conductive layer 40 is formed in an opening 38 making electrical contact with a specified region of the substrate 30. Next, a first hemispherical grained silicon layer 42 and a second dielectric layer 44 are formed over the first conductive layer 40. Thereafter, the second dielectric layer 44, the first hemispherical grained silicon layer 42 and the first conductive layer 40 are patterned. Subsequently, a second conductive layer 46 and a second hemispherical grained silicon layer 48 are formed over the whole substrate structure. Next, portions of the second hemispherical grained silicon layer 48 and the second conductive layer 46 lying above the oxide layer 36 and the second dielectric layer 44 are removed. Finally, the second dielectric layer 44 is removed to expose the first hemispherical grained silicon layer 42. This invention avoids the damaging effects to the first hemispherical grained silicon layer 42 caused by the etching back operation, and prevents the formation of micro-bridges that may erroneously link up adjacent lower electrodes.
