Abstract: Title:  Improvements in or relating to Digital Data Processing Apparatus.                         Abstract This disclosure relates to a modular data processing unit adapted to form part of a processing system comprising a plurality of such processing units connected in master-slave relationship.  Each processing unit comprises a control section responsive to a control instruction to perform the execution of a programme stored therein and to switch the processing unit to an idle mode on completion of the programme execution, an internal memory section including an area of read/write memory; a computation section for performing calculations in accordance with the programme instructions during which i-t can access the internal memory; and interface means through which the processor unit can be connected as a master unit to one or more slave units to monitor and control, and to access the internal memories of the slave units while it is executing a programme, and through which it can be connected as a slave to a master processing unit by which it can thus be monitored and controlled and have its internal read/write memory accessed.   In such a multi-processor system, a master unit may be connected to a number of slave unit each programmed to carry out a particular function, and in turn each of these slave units may be connected as a master -to its own set of slave units, again each programmed to perform a particular function; the whole system being oo-ordinated and controlled by the original master unit.

Abstract: APPARATUS FOR RECEIVING INCANDESCENT COKE               Abstract of the Disclosure There is proposed an apparatus for receiving incandescent coke from a coking chamber and conveying it to a quenching tower which apparatus comprises a wall structure and lining plates secured thereto with the provision for their thermal expansion and defining jointly with a hopper the space for incandescent coke to be conveyed.  The apparatus is adapted for installation on a carriage and removal therefrom to unload coke at the quenching site.  The invention consists in that a spacing means in the form of a corrugated sheet is interposed between the wall struc-ture and the lining plates, the lining plates are joined with one another and with the wall structure with the aid of locking means each comprising a cover piece and a bolt with a nut, and between a round cross-section girdle of the hopper and bottom gates there is disposed a sealing means having a sealing surface contacting the surface of the girdle tangentially.  Various modifications of the spacing means, locking means, and sealing means are presented.       The invention may be utilized in conveying incandescent coke mainly to a dry quenching tower.  It cuts down the coke loss caused by burning and extends the service life of the apparatus owing to an improved thermal conditions of operation of the wall structure.

Abstract: ROLL-ON APPLICATION OF AQUEOUS MICROENCAPSULATED PRODUCTS Abstract A material (14) such as an antiperspirant con-tained in a shear-sensitive, free-flowing, powdery, sus-pension of aqueous droplets stabilized by a barrier of very fine, hydrophobic metal oxide is dispensed from a roll-on applicator. As the ball (18) is rotated, an adher-ent film (22) of the suspension passes through the annular outlet (20) and is subjected to shear forces. The suspension coalesces into a film (24) of cream or lotion. The sus-pension exhibits excellent flowability through the outlet (20) without any binding or fouling and the lotion or cream film has good adhesion to the ball. Application results in a dry feeling on the skin of the subject, a short dry-out time and excellent antiperspirant efficacy.

In players, up-con-version of recovered composite signal precedes comb filtering to separate luminance and chrominance components.  Decoding of up-converted chrominance component, to obtain base-band color-difference signal information is followed by remodulation of a carrier pursuant to a desired output format.  Comb filter arrangements of U.S. Patent No. 3,969,757 are used when up-conversion shifts color subcarrier to a frequency in vicinity of PAL subcarrier frequency, but bearing odd integral multiple relationship to half the line frequency.  Differing comb filter arrangements are employed when up-conversion shifts color subcarrier to PAL subcarrier frequency.  Demodulation/remodulation arrange-ment involving the separate detection and remodulation use of two color-difference signals, as well as system requiring detection and remodulation use of only one color-difference signal, are disclosed.

Abstract: PRESSURE GAUGE CONSTRUCTION            Abstract of the Disclosure Pointer zero adjustment in a pressure gauge is effected by means of a shaft (50) centrally extending laterally inward of the casing from a supportive centering flange (40) on the inside face of the crystal (10).  A Bourdon tube (44) is radially coiled concealed from view through the crystal (10) about a pressure sealed rear por-tion of the shaft (50) to which it is rotationally secured. The pointer unit (42) is of a more or less U-shaped cross section with a tubular center (48) loosely supported on the shaft (50) juxtaposed to the crystal (10).  The front pointer formation (42) simulates a conventional pointer appearance while its rear formation (52) is rotatably linked to the free end (56) of the Bourdon tube for in-curring operational displacement therewith.  On removing a detachable cover (37) from over an aperture (34) in the crystal coincidingly located opposite the shaft end there-at, access is provided for an external tool (78) to opera-tionally engage a tool receiving hex socket (38) in the shaft end.  Arcuately displacing the shaft (50) via the tool (78) calibrationally positions the pointer (42).  By crystal (10) being of a composition and thickness afford-ing a spring rate of matched correlation to maximum antici-pated inlet pressure, the crystal provides a secondary function for relieving overpressure.

The training signal and its ghosts are processed as a finite length sequence of numbers.  The equalizer includes a chain of cascaded filters, the first of which receives the training signal and its ghosts for assuming a filter condition which reduces the finite sequence by two point at the filter's output.  Each successive filter in the chain receives the output of an immediately preceding filter and assumes a filter condition in which an additional two points of the finite sequence are eliminated or forced to  zero.  The filter conditions assumed in response to the training signal and its ghosts are maintained while the data is applied to the filter chain so that ghosts of the type experienced by the training signal are removed from the data.
