Abstract: ABSTRACT:      IMPROVEMENTS IN OR RELATING TO ABSORPTION    OF POLLUTANT MATERIAL FROM A POLLUTED GAS           In a method of absorbing pollutant material e.g. sulphur dioxide from a polluted gas, an aqueous suspension of a solid absorbent e.g. calcium hydroxide is sprayed into the gas;  and the ambient conditions in the gas are such that all the water is evaporated and the absorption product is dried as it is formed.          The spray droplet size is controlled to be a practical maximum consistent with maintaining the ambient conditions.   The spray droplet size may be so controlled that the arithmetical average spray droplet lifetime is at least 80% of the theoretical maximum spray droplet lifetime consistent with maintaining the ambient conditions.

Abstract: TITLE:          TEMPORARY RESTRAINING CLAMP FOR WALLBOARD     ABSTRACT OF THE DISCLOSURE      An integral clamp and screw in the shape of an L has a panel supporting leg and a leg from which a screw projects through and beyond the panel supporting leg.  The clamp is used to support a building panel while aligning said panel over the framing members to which it is to be attached and while fastening the panel to said members.  The screw is turned into a framing member, such as a ceiling joist or wall stud, by turning the clamp by hand until the panel support leg is close enough to hold the panel loosely against the member, putting the panel into place and then turning the clamp further until the supporting leg holds the panel tightly against the framing member.

Abstract: HIGH VOLTAGE SEMICONDUCTOR DEVICES      ABSTRACT OF THE DISCLOSURE               A P-N diode includes a P- substrate with a thin N- epitaxial layer thereon.  A P+ isolation region surrounds the periphery of the N- epitaxial layer and is integrally connected to the P- substrate.  An N+ cathode region extends into the N- epitaxial layer from the upper surface of such layer.  A P+ anode region extends into the N- epitaxial layer from its upper surface and surrounds the N+ cathode region.  A further P+ region extends into the N- epitaxial layer from its upper surface and surrounds the N+ cathode region, and, in turn, is surrounded by the P+ anode region.  The further P+ region is biased at the same potential as the P- substrate.  An N+ buried layer is situated between the P- substrate and the N- epitaxial layer, beneath the P+ anode region, and surrounds the N+ cathode region.  An N+ sinker region extends into the N- epitaxial layer from its upper surface and terminates in integral contact with the N- buried layer, the N+ sinker region surrounding the P+ anode region, and, in turn, being surrounded by the P+ isolation region.  The N+ buried layer reduces parasitic currents in the P-N diode, and the further P+ region, appropriately biased, enables the P-N diode to block current at high reverse voltages.  An N-P-N transistor is structurally similar to the P-N diode, having an additional N+ emitter region diffused into a P+ base region, corresponding to the P+ anode region of the P-N diode.

Abstract: Abstract of the Disclosure A method of image signal coding, the image being subdivided into blocks to be coded in sequence, in which a two-dimensional linear transformation is first applied to each of the blocks, obtaining a set of transformation coefficients. The coding is carried out iteratively by coding at each iteration one of the coefficients of the block with an additional bit as compared to the preceding iteration, and evaluating at each iteration the global error value made if the image block is reconstructed starting from the total number of bits up to now given to the block.  The iterations relating to a block start from the coding of all its co-efficients with zero bits and terminate when said global error becomes lower than a predetermined threshold error.

If the liquid market price of the C3 and/or C4 components is below the fuel price thereof while the liquid market price of a lower molecular weight component is not, the C1-C4 components are further extracted, flashed, and split before returning the desirably priced component or components to the liquid product.

Abstract: ABSTRACT OF THE DISCLOSURE   A privacy signal transmission system has a transmitter including digital pulse modulator for converting a first analog signal into a first digital signal, an encryption circuit for converting the first digital signal into a digital privacy signal and an extractor for extracting a first error signal representative of a difference between a second analog signal provided by analog conversion of the first digital signal and the first analog signal. The first error signal and the first digital privacy signal are transmitted to a receiver which individually generates a second error signal and a second digital privacy signal.  A decryption circuit in the receiver converts the second digital privacy signal into a second digital signal, a digital pulse demodulator converts the second digital signal into a third analog signal, and a reproduction circuit reproduces the first analog signal by adding the error signal to the third analog signal.  Despite the use of inexpensive digital encryption and decryption circuitry  the transmission system is capable of transmitting high quality analog signals.

Abstract: ABSTRACT OF THE DISCLOSURE        The insulated window construction is characterized in having a substantially uniform heat transition coefficient.  The uniformity of the heat transition coefficient is obtained by increasing the distance between the window panes and the heat resistance in the edge region of the window is matched to that in the region of the window area which is undisturbed by the edge.  The edge region is formed by a frame which has a pair of separate metallic frame members which are joined together and spaced apart by non-metallic webs so as to define an insulation path of at least 0.8 times the clearance between the panes.

One end of the electrolyte distribution tube is fixed to an end plate of the plate stack and the second end of the distribution tube may be connected to a Belleville washer or other spring which acts through the distribution tube to compres the plate stack.
