Abstract: A B S T R A C T     METHOD AND APPARATUS FOR TRANSMITTING AN IMAGE       A method and an apparatus for transmitting an image in which the image is sampled at a first plurality of points.  The samples are then subjected to a two-dimensional unitary transform to produce a second plurality of transform coefficients, the second plurality being smaller than the first plurality and being obtained either by selection or truncation of the transform to provide the coefficients containing only the lower frequency components of the image. The transform coefficients are transmitted and on receipt converted by the inverse transform to a second plurality of image samples.  Suitable transforms include the Hadamard and the discrete cosine.          The image transmission is described as part of a viewdata system.

Abstract: CHILD-RESISTANT PACKAGE                  Abstract of the Disclosure A child-resistant package comprising a container and a snap-on closure.  The container has a neck finish including a first upper annular retaining bead and a second lower annular retaining bead spaced axially beneath the first annular bead.  The first retaining bead has a notch therein and the second annular bead is continuous.  An annular protective flange extends radially outwardly and is axially spaced below the second bead.  The closure has a base and a peripheral skirt with a lifting tab on the outer surface thereof, a first radially inwardly extending locking lug on the inner surface thereof adjacent the external lifting tab, and at least one second radially inwardly extend-ing locking lug located diametrically opposite from the lift ing tab and axially below the plane of the first locking lug.          When the closure is assembled to the finish, the first lock-ing lug is located below the first retaining bead and the second locking lug is located beneath the second retaining bead, and when the closure is rotated to bring first locking lug into registry with the notch, the closure can be removed by upward force on the lifting tab.  A stabilizing bead is provided diametrically opposite the lower or second locking lug and cooperates with the lower retaining bead to stabilize the rotation of the closure and prevent any upward movement of the closure when the locking lug is oriented so that it is in register with the notch in the upper or first retaining bead.     i.

Title: Process for continuous digestion of finely-divided  material

Granted: 1987-06-16
Abstract: ABSTRACT OF THE DISCLOSURE           A process is provided herein for the continuous digestion at elevated temperatures of finely-divided material, e.g. wood chips.  The digestion takes place while passing the finely-divided material through a heating zone having an inlet end and an outlet end, then passing the finely-divided material through one or more digesting zones, each having an inlet end and an outlet end, and then passing the finely-divided material through a cooling zone, having an inlet and and an outlet end, in contact with a liquid phase.  The improved digestion procedure includes first feeding a mixture of fresh digesting liquor and the finely-divided material into, and with-drawing a selected amount of a liquid phase from, the inlet end of the heating zone, the feeding and withdrawing being in such relative quantities that their heat-capacity flows are of substantially the same order of magnitude. Spent hot liquid phase withdrawn is then withdrawn from outlet end of the one or more digesting zones.  At least a part of the liquid phase withdrawn from the inlet end of the heating zone is brought into indirect counter-current heat-exchange contact with the spent hot withdrawn liquid phase, the relative quantities of the withdrawn selected amount of liquid phase and the withdrawn spent hot liquid phase being such that the heat-capacity flows of the two liquid phases are of substantailly the same order of magnitude.  Finally cold displacement liquor is fed into the outlet end of the cooling zone, the net quantity of the cold displacement liquor fed being such that the heat-capacity flow is substantially of the same order of magnitude as the heat capacity flow of the digesting material and the liquid content thereof which has been withdrawn from the outlet end of the cooling zone.

Abstract: ABSTRACT             HYDROTHERMAL CRYSTAL GROWING PROCESS         Large single crystals of berlinite are grown onto seed crystals by maintaining the crystals at a fixed elevated temperature in a pressure vessel con-taining a nutrient of coarse berlinite crystalline powder, held at a fixed lower temperature, and a mix-ture of hydrochloric and phosphoric acids.  Because berlinite shows retrograde solubility in the acid mix-ture, the nutrient goes into solution, and berlinite deposits on the higher-temperature growing crystal.          Large single crystals of alpha-gallium orthophosphate may be grown using the same apparatus and a similar process.  The resultant crystals may be cut into wafers useful in surface acoustic wave devices.

Abstract: ABSTRACT     A remote idenfication system particularly suitable for animals. comprises an interrogator gun which generates a directional light beam which the operator can direct at a selected animal up to 30 metres away.  A tag transponder carried by the animal is activated only on receipt of the light beam, and transmits a coded RF signal.  The signal is received by the interrogator which displays the identity of the animal derived from the coded RF signal.  In its "receive" mode, the tag transponder requires minimal power, thereby prolonging battery life.

Abstract: ABSTRACT: Interface circuit.     A voltage dropping element is connected in series with the conduction paths of first and second IGFETs, of complementary conductivity, between first and second terminals coupled to first (e.g. 5 volts) and second (e.g. 0 volt) voltage levels, respectively. The gates of the IGFETs are connected to an input terminal to which is applied TTL level signals (e.g. 0.4 to 2.4 volts) and their drains are connected to an output node  When the "high"          TTL level (e.g. 2.4 volt) is present, the voltage dropping element reduces the effective gate-to-source voltage (VGS) of the first IGFET, reducing its conductivity, increasing its effective impedance substantially, and enabling the second IGFET to drive the output node to the second voltage level with little power dissipation. When the "low" TTL input (e.g. 0.4 volt) is present, the second IGFET is turned-off while the first IGFET is turned-on, driving the output node to the voltage at the first power terminal less the voltage drop of the voltage dropping element. A regenerative latch circuit connected to the output node senses the turn-on of the first IGFET and couples the output node to the voltage at the first power terminal eliminating the voltage offset at the output node due to the voltage dropping element.

Abstract: SPRAYING APPARATUS AND METHOD                         Abstract An improved spraying apparatus utilizes a novel method of withdrawing sprayable liquid from a pressurized vessel at a controlled  rate,  whereby  the  discharge  rate  of  the  spraying apparatus  may  be  preset  or  selectively  controlled  within  a desired range.  Control of the rate at which liquid discharges from the apparatus is effected by pre-setting or regulating the effective size of one or more gas entry openings provided in a liquid  withdrawal  conduit  which  depends  into the  pressure vessel.  The gas entry openings communicate with an upper end region of the vessel wherein a quantity of pressurized carrier gas is maintained.  In one embodiment, all carrier gas must flow through the vessel before being discharged by the apparatus.  In another embodiment, a restricted flow of carrier gas is combined with a mixture of  gas  and  liquid  issuing  from the  pressure vessel for generating a highly atomized, fog-like spray.

During encounters by the ground-working tool with usual types of ground conditions tending to cause the tool to rise against the action of the spring, the assem-bly merely swings upwardly relative to the brack-et.
