Title: Data transfer systems
IPC: H04L5/02
Filed: 1967-02-16
Abstract: In a digital transmission system a carrier is modulated in amplitude, frequency and phase to represent a group of n digits. The embodiment described employs a 4-bit group. One of two frequencies is selected corresponding to the first bit. The selected frequency passes to a circuit which generates four signals differing in phase, and the second and third bits select one of these four signals. The selected signal is modulated in amplitude by the fourth bit and transmitted. At the receiver the signal passes to amplitude, frequency and phase discriminators whose outputs are gated to reconstruct the original 4-bit group.

Patent ES-383046-A1 (ES)
Title: Apparatus for producing de-boned meat products
IPC: A22C25/00
Filed: 1970-08-26
Abstract: Material obtained from animals, poultry, or fish and containing edible flesh along with normally inedible relatively hard or tough components, such as bone, gristle, tendons, etc., is fed in ground condition into one end of a perforated conduit that has a conveyor srew therein which progressively decreases in conveying capacity from the feed end of the conduit to an imperforate discharge end thereof. Such inedible components are compacted within the imperforate discharge end of the conduit by an extension of the conveyor screw prior to discharge following build-up and conveyance along the interior surface of the perforate portion of the conduit as a filter mat through which edible flesh is forced toward and through the perforations of the conduit to provide a substantially bone-free edible product. The discharge passage surrounding the exeension of the conveyor screw can be varied in size, preferably by a tapered ring that is movable back and forth axially of the conveyor screw extension, and preferably the spacing between conveyor screw and conduit is variable. The forward faces of the conveyor screw flights are preferaby concave to provide a forwardly projecting circumferential overhang that tends to keep particles of bone near the axis of the screw, and the conduit wall thickness is unusually thick so as to withstand high pressures. Unusually high production rates can be obtained by feeding finely ground material into the conduit by means of a hgh pressure pump. The discharged and normally inedible components can be slurried in a digestant liquid and the digested material recovered as a food product by the application of centrifugal force. In instances where some minute particles of bone are discharged with the fleshy components, they can be homogenized by subjecting such flesh components to an attrition operation.

Title: Optical readout apparatus
IPC: G01L17/00
Filed: 1974-06-04
Abstract: An air pressure testing apparatus connected to a conventional valve stem of a pneumatic tire is operable to provide visual color information as to the pressure of the air in the tire. The apparatus has a body mounted on the valve stem. A transparent housing having circumferential beads is mounted on the body. A spring biased annular piston located between the housing and body has color code information. Separate colors on the piston are visually observable through the beads as determined by the longitudinal position of the piston relative to the beads. An elongated plunger extended through the body is movable to open the valve in the valve stem to subject the annular piston to the air pressure of the tire. If the air pressure is above a predetermined pressure, the piston will move changing the color code observable through the beads. If the air pressure is below the predetermined pressure, the piston will not move and the color code will remain the same. The plunger is movable to a position wherein air under pressure can be introduced into the tire.
