IPC: A23L17/00
Filed: 1990-05-31
Abstract: ABSTRACT      A large number of fish species exhibit protease activity and are therefore unacceptable for preparing processed fish products such as surimi.  The present invention is directed to a composition containing alpha-2-macroglobulin for inhibiting protease activity contained in the fish material during the preparation of a processed fish product.  Thus, the invention provides suitable proteases inhibitors to treat a number of fish species which were previously unsuitable for preparing processed fish products such as surimi.    The  present  invention  also  relates  to  a  method  of preparing a processed fish product comprising contacting the fish  material   with  alpha-2-macroglobulin  in  an  amount sufficient to neutralize or inhibit the protease contained in the fish material.    In addition, the present invention is directed to a fish product prepared using the composition of this invention and to a fish product prepared according to the method of this invention.

Title: Method of using a circularly-polarized source to characterize seismic anisotropy
Inventor: HORNBOSTEL SCOTT C
IPC: G01V1/00
Filed: 1990-12-04
Abstract: PATENT EXXA,017 METHOD OF USING A CIRCULARLY POLARIZED SOURCE TO CHARACTERIZE SEISMIC ANISOTROPY             Astract of the Invention A method is disclosed for detecting the presence or absence of anisotropy in a subterranean geological formation and for determining its orientation.  In a first preferred embodiment, the method utilizes a seismic source which generates circularly polarized shear waves and directs them to a target formation.  These waves undergo wave splitting on encountering anisotropic conditions and the resulting components are linearly polarized and are reflected to the surface or to a bore hole where they are detected by receivers.  The reflected arrivals are then analyzed to detect the presence  and orientation of the  linearly polarized arrivals as is known in the prior art. In an alternative preferred embodiment, the use of a circularly polarized source is simulated by generating two orthogonal waves linearly polarized 90° out of phase with respect to each other.  Each wave undergoes splitting upon encountering anisotropic conditions in the formation and the resulting components are reflected back to the surface and detected by receivers.      In a preferred receiver embodiment, a first receiver is used to detect the reflected arrivals  of the  first components of each wave.   A second receiver oriented at 90° with respect to the first receiver is then used to detect the reflected arrivals of the second components of each wave.  A first receiver component of a circular source is then simulated by summing the reflected arrival of the first PATENT EXXA,017 receiver component of the first source wave with the Hilbert transform of the first receiver component of the second source wave.  A second simulated receiver component of a circular source is then generated by summing the second receiver component of the first source wave with the Hilbert transform of the second receiver component of the second source wave.  The simulated components are then analyzed to detect the presence  and orientation  of  the  linearly polarized components as is known in the prior art.

Title: Improved controlled deflection roll lubrication
IPC: D21G1/02
Filed: 1990-01-16
Abstract: Apparatus for controlling the oxygenation of both the bearing lubrication oil and the hydraulic oil used for actuating the roll shell support elements (12) in a controlled deflection roll (10), such as used in the papermaking industry, includes a seal (26a, b) at either end of the controlled deflection roll (10) which establishes a gas-impervious seal between the roll shell support and rotation bearings (24a, b) at either end of the roll and the interior (28) of the roll. A source (40) of pressurized inert gas is linked (46, 42) to both the interior of the roll and to the reservoir (38) of hydraulic oil used to actuate the roll shell support shoes (12). This prevents oxygen from interfacing with the hydraulic oil at the only two points in the closed system where the hydraulic oil and the atmosphere would otherwise come into contact. A separate bearing oil lubrication system (32, 34, 35, 36) having its own reservoir is maintained to supply bearing lubricant to the bearings (24a, b) and return it to sump (20) while maintaining the bear-ing lubricant separate from the hydraulic oil.

Abstract: A thermostatic valve has a valve housing (1) and a thermostat top part (2) with a base foot (7).   The latter is surrounded by a rotatable retaining ring (11) and can be pushed onto the valve housing (1) until it engages an abutment face (14) of the valve housing (1). The valve housing (1) has a tapering clamping face (16).   In the retaining ring (11), at least one clamping element (17) can be pressed against the clamping face (11) in order to press the thermostat top part (2) against the abutment face (14).

The clamping element (17) bearing against the guide face (19) is adjustable through rotation of the retaining ring (11).   The retaining ring is rotatable against spring force for the purpose of pulling back the clamping element (17), and, as the base foot (7) is pushed onto the valve housing (1), a locking ring (30) is arranged to be displaced axially against spring force from a locking position, in which the clamping element (17) bears against the locking ring circumference, into a releasing position, beyond the path of movement of the clamping element (17).
