Abstract: CODEC ABSTRACT OF THE DISCLOSURE A codec using charge redistribution techniques, which requires substantially reduced chip area as compared to previous codecs of this type, and only one power supply voltage supply to ground, previous codecs requiring two such supplies.  The codec is comprised of a first plurality of capacitors having one terminal of each capacitor connected in common, a circuit for switching the common terminal of the capacitors to a first reference voltage, and a circuit for selectively switching the other terminal of each capacitor between a first lead and a second lead.  A further circuit selectively switches the first lead between a source of the input signal, the first reference voltage and a high impedance.  A second plurality of capacitors has one terminal of each capacitor connected in common.  A buffer has its input connected to the common terminal of the second plurality of capacitors, and its output connected to the aforenoted second lead.  A switching circuit switches the input of the buffer to the the first reference voltage and a further switching circuit selectively switches the other terminal of each of the second plurality of capacitors to a third or a fourth lead.  An additional switching circuit switches the third and fourth leads interchangeably to the first reference voltage and a second reference voltage.  Upon switching of sequences of the other terminal of capacitors of the first plurality of capacitors between the first and second leads, a distribution of charge is effected therebetween, and upon switch of sequences of the other terminal of capacitors of the second plurality of capacitors between the third and fourth leads a distribution of charge is effected therebetween.  An output circuit carries an output signal from the aforenoted one terminal of the first plurality of capacitors resulting from the distribution of charge between the first capacitors and the distribution of charge between the second capacitors.  With the first reference voltage at ground potential, only a single power source voltage is required.

Abstract: ABSTRACT OF THE DISCLOSURE      Rod-like tools mounted on gears so as to be swung together and apart by a reciprocating drive and running across a conveyor intermittently moving loaded egg containers, likewise oriented across the conveyor, are moved together to fold over the top corrugated strips of the upstanding sides of the egg container, as presented to the machine, by 90°, to bring these strips into abuttment.          Each corrugated strip is backed by a flat strip and one of the two has tabs which are folded over by 180° and adhesively bonded to the other flat strip.  The folding over of the tabs is performed by a set of fingers that move between segments of the first-mentioned folding tools to raise the tabs at an oblique angle, after which push rods bend them over completely.  During these operations  adhesive is applied to the surfaces to be bonded so that the tabs will hold the container together after the first-mentioned folding tool and the finger and push-rod assembly are moved back out of the way of the transport path of the container so that the containers on the conveyor can proceed to the next station.

Abstract: IMPROVEMENTS IN ULTRASONIC EXAMINATION AND IMAGING A ultrasonic imaging device comprises transducers distributed along a line and operable at a frequency f. A generator delivers electrical pulses to time delay means which provide, in response to each electrical pulse, a plurality of low level pulses delayed by increased time delays in a number lower than the number of transducers. The distribution of the time delays between the transducers is stored in memory means and corresponds to focusing at a point located at a predetermined distance from the line. A plurality of amplifiers are each associated with an individual one of the transducers and deliver an energizing pulse to the associated transducer in response to a particular one of the low level pulses appearing on an associated channel of a bus line which is selected by the memory.

Abstract: Wave Powered Motor Abstract A dome-shaped atoll structure (12) having a central aperture at its apex is secured to a station-keeping structure (11, or 40, or 52) posi-tioned on the ocean bottom.  The atoll structure (12) is moveable through a range of vertical positions relative to the ocean bottom.  Sea waves impinging on the atoll structure (12) are refracted as they crest and break, thereby producing spiralling pulses of water that converge toward the central aperture.  The central aperture provides entry into a vertical standpipe (14) for the pulses of water, which impart angular momentum to water already present in the standpipe (14).  A turbine (31) attached to a shaft (26) in the standpipe (14) to rotational energy of the shaft (25), which is coupled to an electrical generator (27).  The elec-tric power output of the generator (27) is measured for various vertical positions through which the atoll member (12) is moved, so that a posi-tion of optimum power output can be determined for any given combination of see state and/or tidal conditions.

A valve mandrel is slidably received in the housing and movable from a closed position closing the circulating port to an open position opening the circulating port.  The valve mandrel includes an annular piston received in the housing for moving the valve mandrel from its closed position to its open position. The power port communicates the piston with a pressure exterior of the housing.  A frangible restraining structure is located between the valve mandrel and the cylindrical housing for restrain-ing movement of the valve mandrel from its closed position to its open position until the pressure exterior of the housing exceeds a predetermined value, and for frangibly releasing the valve mandrel when said pressure exterior of the housing exceeds said predetermined value.  The frangible restraining structure includes a carrying structure arranged for force transmitting engagement with a surface of the valve mandrel.  The carrying structure in-cludes inner and outer concentric sleeves with the inner sleeve being arranged for said force transmitting engagement with the surface of the valve mandrel.  Shear pins are connected between the inner and outer concentric sleeves and arranged to be sheared upon relative longitudinal movement between the inner and outer cylin-drical sleeves.

Abstract: "SIMULATED COUNTERCURRENT SORPTION PROCESS EMPLOYING        ION EXCHANGE RESINS WITH BACKFLUSHING"                                 ABSTRACT         A process for separating a selected component from a fluid mixture of components by employment of an ion exchange resin.  Fluid flow is maintained through a column containing the adsorbent in at least three separation zones, an adsorption zone in which the selected com-ponent is adsorbed by the adsorbent, a purification zone and a desorption zone from which the selected component is displaced by a desorbent material. There is also a backflushing zone, upstream of either the feed or desorbent stream inlets, in which the direction of fluid flow is opposite the direc-tion of flow through the three separation zones.  The zones are periodically shifted through the column by advancing the input and output streams.  The backflushing serves to decrease the density of the resin bed thereby con-trolling the pressure drop developed through that bed when it is in service as part of a separation zone.  The ion exchange resin particularly suitable for the invention is an alkali metal salt of a nuclearly sulfonated styrene-cation exchange resin containing a cross-linking agent.  The process of the invention is particularly suitable for the separation of a saccharide from an aqueous solution of saccharides.
