Abstract: ABSTRACT OF THE DISCLOSURE       A seat for a childs swing is of composite structure having a first member, which is sufficiently rigid to bear the weight of a child, and a second member made of a compressible polymeric material.  The first member is substantially laminar and the second member covers at least part of the peripheral edge of the first member.  The force-deflection characteristic of the second member is such that, on any impact with an object, the second member initially deforms to conform with the shape of the impacted object and then deforms further to absorb the main energy of the impact.

Granted: 1978-11-07
Abstract: A B S T R A C T           This invention consists of an automatic fish feed-ing device which is controlled and operated electrically and which can be set to go on and off at predetermined times, thus eliminating personal attention when such attention is not avail-able.  The feeding mechanism consists of a hopper which con-tains the fish food, and a conveyor screw at the bottom of the hopper for carrying the food to, and discharging it into an aquarium to which the device is attached.  The "ON" and "OFF" timing can be controlled by means of a standard household timer or by any one of a number of more sophisticated time control devices at present on the market, and the R.P.M. of the con-veyor determines the quantity of food delivered to the aquarium, during a predetermined period of rotation.

Abstract: ABSTRACT OF THE DISCLOSURE         Apparatus for calculating and displaying dive related information is constructed in the form of a general digital com-puter that operates under software control to manipulate  math-ematical decompression model of a human body in a variety of ways.          The circuitry of the computer employs LSI technology and is built about a central processor unit having a characteristic complement of peripheral circuits such as PROM and RAM memories, A-D and D-A converters, I/0 devices and other circuits to attend to nor-mal housekeeping duties.  Communication between the processor unit and its peripheral circuits occurs via a parallel, eiqht bit bidirectional bus.  Instructions and related data defined by predetermined programs are permanently stored in the PROM memory and are retrieved and sequentially executed in response to operational command instructions input from an alphanumeric key-board.  The keyboard is used in a novel matrix arrangement having its input coupled to an output port and its output feeding select-ted bits to the processor unit as coded command instructions and data words along a portion of the bus.

Limit means cooperate with the tumblers for preventing the member from being shifted except when the tumblers are set in the correct combination. The member can be shifted in response to movement of the shackle of the padlock, but only when the lock is open. The bolt of the padlock and the shackle are designed to permit the tumblers to be scrambled when the lock is open, thus concealing the correct com-bination from unauthorized persons, and preventing the combination from being changed while the lock is open.

Abstract: RECORD TRACK FOLLOWING AND SEEKING                        Abstract An improved servo block pattern bands a plurality of parallel record tracks into a track seek and follow band.          Servo block positions in the record tracks, plus the lon-gitudinal duration of the signal bursts enable simultaneous track seeking and following within a band of tracks.  Servo apparatus operable with such patterns adapt to amplitude variations of the servo readback signal to reduce the effect of amplitude variations on servo performance.  The servo blocks may have differing frequencies or correlation patterns for enhancing track seek and follow functions.

Abstract: ABSTRACT OF THE DISCLOSURE         A head for producing magnetic images of fine detail, including a group of recording elements spaced perpendicular to the movement of a magnetic tape and a power source that passes current pulses through the recording elements to create magnetic fields that magnetize small regions of the tape.  Each recording element includes an elongated conductor with a thin nickel layer nearest the magnetic tape and a thick copper layer on the side of the nickel layer opposite the tape, the copper layer having a small gap therein at a predetermined recording location.  Accordingly, the center of current flow is normally through a middle portion of the copper which is too far from the magnetic tape for the resulting magnetic field to magnetize the tape, except at the recording location where the current passes through the nickel layer which is close enough to the tape to magnetize it.

Abstract: DETERMINATION OF REFLECTIVITY AND WATER  DEPTH FOR FIRING MARINE SOURCES AS AN     INVERSE DISTORTION OPERATOR            Abstract of the Disclosure In marine seismic exploration, seismograms recording reflected energy generated from conventionally fired sources are used to measure the characteristics of the medium through which the energy passed.  These measurements are converted into control parameters for the sources.  When the sources are fired under control of these parameters, seismograms having enhanced reflections are produced.  As an example, simultaneously fired sources produce seismograms which axe used in the measurement of water bottom reflectivity and water depth.  The measured reflectivity and water depth are converted into a time domain operator representative of the inverse of the reverberation distortion in the water layer. The array of sources is then fired in a sequence which produces an acoustic pressure wave having the inverse time domain characteristics.  The sources are alternately fired simultaneously and in groups producing said inverse time domain operator.

Abstract: ABSTRACT OF THE DISCLOSURE    A check valve has a clapper pivotally mounted inside of a flow passage which clapper is formed by investment casting.          The clapper of the check valve will only allow fluid flow in one direction.  The face of the check valve has an annular groove formed therein and a recessed center portion.  After a base surface is cut in the backside of the clapper, a molded rubber seal is formed on the face of the clapper with the seal extending from the annular groove with raised annular surfaces and a web covering the center portion.  Upon receiving reverse flow through the check valve, the clapper will immediately close and seal against a valve surface.  The raised annular surfaces deform into the annular recess therebetween allowing metal-to-metal contact between the clapper and valve surface, while simultaneously maintaining a good rubber seal contact.

Abstract: ABSTRACT OF THE DISCLOSURE      Apparatus and method are included in the main memory of the data processing system which receives data from a plurality of input/output devices connected to a common bus. During a write cycle of operation, a device applies a plural-ity of data byte signals together with associated parity bits for writing into an addressed storage location of memory. Error detection and correction encoder circuits are connected to receive the data bits and parity bits and from them gener-ate check code bits which are coded to signal selectively the presence of an uncorrectable error condition in accordance with the parity bits from a given source.  During a read cycle of operation, error detection and correction decoder circuits connected to the memory in response to the data and check code bits read out from an addressed location are opera-tive to generate a number of syndrome bits having a predeter-mined characteristic for indicating the existence of an un-correctable error condition when the parity bits associated with data signals when written originally into memory if checked would have indicated that the data was in error.
