Title: Apparatus for providing an analog or the like of the angular velocity of a rotating body
IPC: G01P3/48
Filed: 1972-08-01
Abstract: Two magnetic pickups are fixed around a toothed, ferromagnetic rotating wheel in positions such that they produce output signals which are approximately sine wave in shape and in phase quadrature. Each pickup output is introduced to a different corresponding multiplicative mixer. One mixer receives a carrier input in addition. The other mixer receives the carrier shifted in phase by 90 DEG . The outputs of mixers are introduced to an adder. The output of the adder is then free of carrier upper sideband. The lower sideband may then, if desired, be transmitted over long distances without a loss of accuracy. A.D.C. voltage, if desired, may then be developed directly proportional to the frequency of the lower sideband by a frequency discriminator. This voltage is then directly proportional to the wheel velocity. Moreover, the resolution of this volocity analog is high and to within one cycle of the high carrier frequency.

Patent ES-448641-A1 (ES)
Title: Process for the production of protein filaments from a cooked meat source
IPC: A23L13/00
Filed: 1976-06-08
Abstract: A method of continuously forming elongated protein filaments from a cooked meat source is disclosed which comprises forming an aqueous slurry of a cooked meat source having a solids content of at least about 10 percent by weight and a pH of between about 3 and 10, followed by treatment of the noted slurry to provide a pumpable slurry with a viscosity ratio, as measured at a solids level of 15 percent by weight, to an uncooked meat slurry of substantially identical composition of at least about 1:2. Elongated protein filaments are thereafter formed from the slurry by continuously conducting the slurry under pressure through a heat exchanger and heating the slurry to a critical temperature of at least about 280 DEG F. and preferably between about 310 DEG - 335 DEG F. while the protein is subjected to such temperature for a sufficient period of time so that elongated filaments are separated from the slurry. A higher temperature range is necessary with a "cooked" rather than uncooked protein source since it has been determined that once the protein source has been cooked it takes more heat to convert it to a protein filament than is required with an uncooked material. The heated slurry is continuously removed from said zone through an orifice and discharged into a collecting zone whereby the elongated filaments are separated from the remaining constituents of the slurry. The noted process provides a distinct improvement over prior art processes which were dependent upon the need for an "uncooked" protein source to permit texturization, and discloses a critically defined set of temperature conditions for the production of protein filaments from a protein source which heretofore has been considered unusable in texturization processes.
Patent ES-449050-A1 (ES)
Title: Pressure operated isolation valve for use in a well testing and treating apparatus, and its method of operation
IPC: E21B49/08
Filed: 1976-06-18
Abstract: In a well testing tool having a spring whose biasing force is supplemented by the hydrostatic pressure in the well annulus at the testing depth, a method and apparatus for isolating the spring from the pressure in the well annulus utilizing the pressure differential between the well annulus and the testing tool bore which exists after the formation is isolated and for maintaining the isolation of the spring force during subsequent interior bore pressure increases such as during formation treating operations. An isolation valve is provided whose closing force is generated by isolating the testing tool bore from the well annulus, and then increasing the well annulus pressure above the hydrostatic pressure. The pressure differential thus created is utilized to close the valve. Uni-directional acting means is provided in the isolation valve responsive to the interior bore pressure such that when the interior bore pressure is increased subsequent to the closing of the isolation valve, the uni-directional acting means will not cuase the isolating valve to reopen, but will nullify the effect of the subsequent pressure increase such that the valve will remain closed. The opening force is provided by compressing a spring when the valve is closed, thus allowing the isolation valve to reopen when the pressure in the annulus is returned to hydrostatic. An isolation valve is provided which is normally open, which closes only after the well annulus pressure exceeds a reference presssure trapped in the bore of the testing tool by a predetermined amount, and which remains closed during subsequent pressure increases in the bore of the testing tool.
