Abstract: ABSTRACT           A pressure sensor for indicating pressure in the animal or human body, such as intracranial pressure, including a housing, a bellows contained within the housing, a body pressure sensing tambour for placing the bellows in communication with pressure in the body so that the pressure will cause the bellows to move as a function of the pressure, output means, such as a radioactive source and associated shielding, contained within the housing and associated with the bellows for providing an output which is a function of the movement of the bellows, and a receiver, such as a radiation detector, located external to the body to receive the output and provide data indicative of the pressure in the body. The pressure sensor includes means associated with the bellows to enable in vivo calibration of the pressure sensor after implantation by establishing a pre-selected output condition during calibration. An ambient pressure sensing tambour is associated with the bellows for compensating for ambient pressure variations. The bellows is resilient, made of a material and shape which has 100% memory of elastic deformation and has n wall thickness of less than 0.001 inch, in order to provide an output which accurately reflects the pressure being monitored. The bellows has a spring rate which is substantially greater than the spring rate of the pressure sensing and ambient pressure compensating tambours thereby making the pressure sensor essentially insensitive to temperature variations.

Title: Ground station data storage system
Inventor: WEST LOUIS R
IPC: G01S5/02
Filed: 1977-10-05
Granted: 1980-11-18
Abstract: Abstract of the Disclosure Data relating to the attitude and spin rate of a spacecraft is stored in a data storage system located at an earth station in communication with the spacecraft.      Leading and trailing edges of the data, usually in the form of pulses, received from sensors suitably mounted on the spacecraft, address locations in a random access memory (RAM) into which the count accumulated in a counter is written.  At the end of each group of pulses, referred to as a frame, data relating to the status of the pulses received from the spacecraft is also loaded into the random access memory.  Simultaneously, a computer is signalled that a complete frame of data has been loaded in the random access memory.  The computer then generates address and other signals such that the data can be read out of memory and thereby allow the computer to calculate the attitude and spin rate of the spacecraft.

Abstract: ABSTRACT    A high speed system is provided for bringing a plurality of articles, each moving independently in a separate path and at its own speed into registration with each other at a processing station.  In applying the invention to a case making machine, successive boards are brought into registration with successive sheet areas defined on a continuous web which moves at a predetermined constant speed.  Each board moves at a speed greater than the web speed until registration with the desired sheet area is obtained.  A counter measures the registration differential between predetermined detection indicia on each article by keeping track of the distance travelled by each indicium beyond a reference position in the path of the corresponding article.  When registration is obtained, the articles are transported at a common speed to the processing station where the separate paths converge.

Abstract: Abstract of the Disclosure A flow passage having a restriction is connected between a fluid inlet and outlet.  An internal bluff body such as a frustum or disc is disposed in the flow passage between the inlet and the restriction.  The inlet is transverse to the axis of the flow passage.  The internal bluff body is mounted on a rod extending through the flow passage.  The rod may be hollow and have holes near the restriction for the purpose of liquid feed.  As fluid entering the inlet passes the rod and bluff body to the restriction, a vortex is generated.  A bluff body is disposed at the outlet external to the passage to interrupt vortically flowing fluid.  A resonator is disposed at the outlet external to the passage to intercept fluid flowing vortically through the passage.  The external bluff body lies between the outlet of the passage and the resonator to interrupt fluid flowing through the passage.

Abstract: ABSTRACT OF THE DISCLOSURE        A machine for automatically manufacturing batches of concrete blocks incorporating foamed polystyrene inserts on mating contact with the concrete of the blocks comprises a magazine for the inserts, a mould for a batch of blocks, a bin and truck arrangement for storing then transferring concrete grout to the mould, and another truck for transferring batches of inserts from the magazine to the mould.  The mould is open at the bottom and can be held in a raised position above the floor and then lowered to the floor which then closes off the bottom of the mould.           In the process using the machine, a batch of inserts is transferred to the mould when it is in its raised position and are secured within the mould by impalement on spikes mounted on the underside of a cover plate forming the top of the mould.  The mould is then lowered until closed off by the floor. A suitable quantity of grout is transferred to the lower mould where it is compressed by a ram and compacted by a vibrator. When the concrete grout has set the mould is drawn upwards off the finished blocks leaving them on the floor which is fixed if the remainder of the machine is movable, or is movable if the remainder of the apparatus is fixed.  The inserts in the block thus formed are embedded in the concrete in mating contact therewith.  The machine operates respectively making a series of batches of blocks.

Abstract: LORAN-C NAVIGATION APPARATUS                    Abstract of the Disclosure LORAN-C navigation apparatus is disclosed wherein digital circuitry and a microprocessor is used to automatically identify LORAN transmitting stations and makes standard hyberbolic navigation measurements. The equip-ment operator manually enters the group repetition rate into the apparatus for a LORAN-C chain covering the area within which the navigation apparatus is being operated. Initially, the apparatus searches all incoming signals until signals from a master station are received regularly at the stored group repetition rate. The apparatus then closely determines the time of arrival of signals from the secondary stations of the selected LORAN-C chain before changing to a fine search mode in which the exact time of arrival of the secondary station signals is determined; the phase code of the received signals is checked to determine if the received signal is a ground or sky wave and a determination is made if there is a defective secondary station blink code. The time difference of arrival measurements are then output visually to be plotted in a well known manner on a LORAN-C chart to locate the posi-tion of the craft upon which the apparatus is located.

BELDEN                          ABSTRACT         A process for separating hydroxylamine from an aqueous solution containing hydroxylammonium salts in mixture with salts of predominantly monovalent cations whose corresponding free bases have base dissociation constants greater than 10-7.  Said solution is passed through a bed of cation exchange resin loaded predominantly with monovalent cations whereby hydroxylammonium and the other cations in solution substantially displace said cations from the resin. A second aqueous solution containing a monovalent amine or hydroxide base of at least 0.5 molar concentration having a dissociation constant greater than 10-7 is passed through the resin bed whereby hydroxylamine is preferentially released to the solution and the resin is correspondingly loaded with the cation of said base.  Hydroxylammonium salts can be crystallized from the solution after addition of a stoichiometric amount of an appropriate acid.
