Patent EP-0321395-A2 (EP)
Inventor: BIERI HANS
IPC: B23B51/04
Filed: 1988-11-23
Abstract: A top coupling part (1) contains a recess in which a projecting coupling extension (20) of a bottom coupling part (2) engages. The two coupling parts (1, 2) can be separated from one another by a pure axial movement and are held together by a cap nut (3). The top coupling part (1) is connected to a rotating drive unit (13) by a threaded stem (4), and the bottom coupling part (2) is connected by a threaded stem (15) to a tubular cutter (14) of large diameter for working concrete. 
<??>The two coupling parts can easily be separated by this coupling device even after the transmission of high torque, since the cap nut (3) is not involved in the torque transmission and therefore no jamming occurs.

Abstract: For bending hollow distance profiles (2), in particular those filled with a desiccant, preferably for panes of insulating glass, the profile (2) can be advanced during bending and a bending tool (4) can be moved towards and away from it, oscillating with respect to the abutment (3), the profile (2) expediently being advanced during the moving away of the bending tool (4) and a point on the profile (2) adjacent to the previously bent point being acted upon and bent during the next movement of the bending tool (4) towards the abutment. A very wide variety of arcs and radii of curvature can thereby be produced depending on the speed of advance of the profile and the bending frequency or also bending stroke of the bending tool.   <IMAGE>

Abstract: A method for reading data blocks from main memory by central processing units in a multiprocessor system containing write-back caches. Load or gather instructions contain a write-intent flag. The status of the write-intent flag is determined. It is also determined whether a data block requested in the instruction by one of the processors is located in a corresponding cache, and if so, the requested data block is returned to the processor. If the data block is not in the cache and the write-intent flag indicates that the block will not be modified, the data block is read from main memory without obtaining a write privilege. The requested data block is subsequently returned from the cache to the processor. If the data block is not in the cache and the write-intent flag indicates the data block will be modified by the processor, then the data block is read from main memory while obtaining the write privilege. Subsequently, the requested data block is returned from the cache to the processor.

According to another method, a sintered body of a Bi-based superconductive oxide containing Pb may be manufactured such that a Bi oxide powder and a Pb oxide powder are mixed in predetermined proportions, and sintered at a predetermined temperature into a Bi-Pb-O oxide sintered body. The Bi-Pb-O oxide sintered body is crushed into a powder, followed by mixing the powder with a Bi-Sr-Ca-Cu-O oxide powder in predetermined proportions into a mixed powder. The above Bi-based superconductive oxide sintered body is formed from the last-mentioned mixed powder.

Abstract: A method for producing zein-coated sweetener-containing particles and a method for producing chewing gum containing such particles as a delayed release protein sweetener. The delayed release protein sweetener is obtained by forming an aqueous solution of gelatin and a protein sweetener comprising thaumatin and/or monellin. This solution is dried and particle sized to thereby produce sweetener-containing particles of a gelatin matrix. A quantity of these particles is mixed with a limited quantity of a solution of zein. Preferably, the zein is dissolved in water with a pH between about 11.5 and about 12.1. The quantity of the zein solution being added is limited to thereby produce a damp mix which is dust free, non-flowing, and crumbly. The damp mix is dried and then particle sized to thereby produce zein-coated sweetener-containing particles within a predetermined particle size range, which particles can be added to a chewing gum formulation.

Abstract: Methods for quickly determining loss of synchronization and for quickly reestablishing synchronization of a sub­aggregate frame having primary and secondary frames and contained within an independently synchronized aggregate are provided. In determining loss of synchronization, synch bits are located in the secondary frame such that when the composite subaggregate frame is synchronized the synch bits are chosen to be inserted into the same predetermined position in the aggregate. The synch bits are provided with values such that a collection os synch bits of a composite frame provides an internally non-repeating pattern. By comparing bit values received in the predetermined location of the aggregate at the synch bit rate with the non-repeating pattern, a determination is made as to whether synchronization has been lost. To reestablish synchronization, during data receipt, the bits located in the predetermined synch bit location in the aggregate frame are sequentially inserted into a number of buffers, the number being equal to the frame rate of the aggregate divided by the synch rate of the synch bits. Then, upon loss of synchronization, a local pointer value is stored upon receipt of a synch bit candidate, the bit patterns in the buffers are scanned to find the buffer containing the internally non-repeating synch pattern, and a pointer correction indication is determined by comparing the local pointer value to a system pointer value dictated by the internally non-repeating synch pattern in that buffer.

Abstract: Butterfat spreads include products with around half the fat of butter. Around 15-20% of the fat-phase in butter is solid at 20°C. When butter is placed in the mouth this fat melts, produces a cool sensation on the palate. Low fat content attenuates the cool-melting properties, while adding stearins to the product can cure the mouth melt problem but gives a product which is hard when removed from the refrigerator. 
     The specification discloses a low fat butter spread in which the distribution of stearin in the product is inhomogeneous such that the C/N*N at 10°C is less than 0.35. This spread is cool melting without being hard at fridge temperature. 
     The specification also discloses a process comprising the step of mixing of a pre-crystallized viscous butter stearin cream, having a gelled or thickened aqueous phase, with a fat-continuous emulsion of whole butterfat and water, preferably in a 30:70 ratio, to obtain these products. 
     Preferably the aqueous phase viscosity of the butter stearin cream is greater than 50mPa.s at 20°C as measured at a shear rate of 181 rpm after a resting period of 30 min.
