Patent ES-470760-A1 (ES)
Title: Servo control for X-ray tomography
IPC: A61B6/02
Filed: 1978-06-14
Abstract: Apparatus for plan-parallel tomography comprises an X-ray tube and detector which are mechanically connected to each other by means of an extendable column consisting of two portions. Linear movement of the X-ray tube is obtained by sliding the two portions during the swiveling of the column. The use of customary servo control arrangements for sliding in or out, however, involves a position error which is approximately proportional to the sliding speed of the column portions. This position error is eliminated by the adding of a correction signals which is proportional to the sliding speed into the servo control signal.

Title: Multifrequency signal receiver
IPC: H04Q1/453
Filed: 1978-07-26
Abstract: Detection of valid two-out-of-N multifrequency signals is realized by employing a microprocessor in conjunction with a controllably adjustable or settable reference threshold level (107) and a plurality of threshold detectors (104-1 through 104-N). Under control of the processor, a reference threshold level supplied to the detectors is set to a first prescribed level. Upon detection of a tone which exceeds the first threshold level the processor controllably sets the reference threshold level to a second prescribed level. Detection of two, and only two, tones which are present for at least a minimum prescribed interval are level. Detection of two, and only two, tones which are then considered valid.

Title: Canned clam product
IPC: A23B4/02
Filed: 1978-10-04
Abstract: Canned clam meat food products suitable for human consumption are prepared from previously underutilized clam species, such as the ocean quahog, which develop a disagreeable odor, flavour and colour upon canning, by adding a treating agent selected from the group consisting of sodium bisulfite, sodium metabisulfite, and mixtures thereof, to the clam meat prior to in-can retorting. The treating agent can be added to clam meat in the can immediately prior to sealing and retorting, or during the boiling of a slurry of clam meat in water or expressed juices before the meat is placed in the can. In another embodiment, the edibility of clams such as the ocean quahog is improved by boiling a slurry of clam meat in water or expressed clam juices to drive off the substances which cause the development of disagreeable odor, flavour and colour upon canning.
