Abstract: PROCESS AND APPARATUS FOR CONVERTING:        COAL INTO LIQUID PRODUCTS                 ABSTRACT OF THE DISCLOSURE     The invention provides a process and an apparatus for hydrogenative liquefaction of coal to produce high yields of gasoline fraction and optional yields of diesel and residue fraction, all of superior quality.  The coal is slurried and digested in two separate and distinct streams.          The pasting oil of the first stream is heavy residue fraction derived to a substantial extent from the second stream, preferably mixed with light oil derived partly or wholly from the first stream.  The pasting oil of the second stream is middle oil derived from the fractionated discharge of the first stream, any shortfall being made up from the discharge of the second stream.  A high degree of flexibility is possible by varying the ratio of coal fed to the respective streams between 3:1 and 1:3, and indivi-dual manipulation of the process parameters within each stream in respect of pressure, temperature, catalyst, residence time, pasting oil composition and coal quality.

Abstract: INDUCTIVE HEATING APPARATUS                 ABSTRACT OF THE DISCLOSURE          Inductive heating apparatus includes serially connected first and second transistors which are alternately caused to conduct by a control circuit.  A resonant circuit including an induction heating coil and a capacitor is connected in parallel with the second transistor.  When the first transistor conducts a first current flows to charge the capacitor and when the second transistor conducts a second current flows in the resonant circuit to discharge the capacitor. The control circuit produces a turn-off signal to the conducting transistor before the current through the conducting current falls to zero and also produces a turn on signal to the nonconducting transistor when the current through the conducting transistor reaches zero.

Abstract: ABSTRACT A method is disclosed for separating off acids or bases carried along with the vapours formed by distillation during concentration of acids and bases. The vapours are passed at their existing pressure and temperature through a salt solution which boils at this temperature and pressure.  If acids are to be removed from the vapours, the salt solution contains a salt with an anion corresponding to that of the acid and an amount of a base having the same cation as the salt is added to neutralize the acid.  If bases are to be re-moved, the salt solution contains a salt with a cation corresponding to that of the base and an amount of the acid required to neutralize the base in the distillation vapours is supplied to the salt solution, the anion of the acid corresponding to that of the salt.  The salt formed during neutralization thus corresponds to that of the salt solution.

Abstract: ABSTRACT     The present invention relates to a mechanical press, and in particular to a guiding arrangement for the reciprocating slide of such a press. The press comprises a crown (20), the bed (14) and a plurality of vertical uprights (18) connecting the crown and bed. A plurality of guideposts (58) are rigidly connec-ted to the crown and depend downwardly therefrom, the guideposts being parallel to each other and substantially perpendicular to the plane of the bed.  The guideposts each have free ends which are unsupported and terminate short of the bed of the press so that the parallelism of the guidepins is determined solely by their connection to the crown. In order to counteract the non-vertical forces exerted on the slide (56) by the connection arms (142) which tend to cause the slide to tilt about a horizontal axis perpendicular to  the axis of the crankshaft, bearings (250) are mounted between the connection assembly and the crown.  The bearings exert restraining forces on the connection assembly in a direction perpendicular to the axis of reciprocation of the slide and long lines which intersect the axis of rotation of the wrist pins (152)  In a preferred embodiment of the invention, the bearings are gydro-static bearings (250) interposed between the connection pistons and their respective cyclinders (158) although hydrodynamic roller bearings could be used.

Abstract: ABSTRACT     An optical measurement technique enables optical signal processing apparatus to eliminate the effects of environmental noise during scanning of a workpiece wherein successive optical slices through the workpiece are obtained. The image samples derived by the scanning optics may not properly line up with one another where there is relative vibrational motion between the workpiece and the scanning optics. To overcome this problem a reference marker/ correlation scheme effectively aligns each of the picture slices of the workpiece relative to a stored reference marker by correlation so that the composite of the adjacent samples of the stem accurately represents a picture of the workpiece.
