Abstract: AIR SPRING ASSEMBLY            ABSTRACT OF THE DISCLOSURE         A heavy duty rolling lobe air spring which has an open hollow piston providing a reservoir and an outer surface on which the lobe of a flexible sleeve rolls, the surface including a horizontal top, a gently curved outer surface joining an inverted frustro-conical side and terminating in an outwardly flared bottom portion.  The side walls have an angle with respect to the axis of the piston greater than 20° and preferably about 23°.  The volume of the piston and the sleeve, and the angle of the frustro-conical surface are such that the effective area of the sleeve decreases under jounce and the spring rate is in the range of 100 to 300 pounds per inch (17.5 - 52.5 KN/m) at a design load in the range of 1000 to 8000 pounds (454 - 3629 kg).  The ratio of load to spring rate is thus above 20 inches (50.8 cm) at design loads in excess of 5000 lbs (2268 kg).

Abstract: ABSTRACT      Insolublised antibodies, F(ab')2 fragments thereof and protein antigens are made by coupling to a water-insoluble substrate using a bridging agent which covalently binds to sulphur atoms in antibody, fragment or protein rather than to free amino groups therein.  This is preferably effected by using a chloracetyl-terminated bridging agent.  Immunoassays utilising these insolubilised reagents are described. One novel class of bridging agents comprising anhydride and monochloracetyl end groups, which is useful for making the said reagents, is also disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE      Pneumatically-conveyable particulate material is withdrawn from a hopper using vacuum wands extending into the interior of the hopper.  The wands are operated in a cyclic sequence, with material being withdrawn from each wand in turn.  This permits material to be withdrawn substantially continuously where the material tends to compact together in flow-preventing bridges and the invention can be put into practice employing a relatively simply applied attachment connected on the exterior of the hopper.

Abstract: ABSTRACT:            Because the deflection fields in colour tele-vision display tubes on the display screen side often have a pin-cushion-shaped and barrel-shaped field distribution, a defocusing of the electron beams occurs upon deflection. By deforming the deflection field which is barrel-shaped on the display screen side of the deflection yoke so as to be pin-cushion-shaped near each electron beam on the neck side of the deflection yoke and simultaneously deforming the deflection field which is pin-cushion-shaped on the display screen side of the  deflection yoke so as to be barrel-shaped near each electron beam on the neck side of the deflection yoke, the effects of said defocusing of the electron beams as a result of the deflection are con-siderably reduced. The haze occurring in the vertical dir-ection is also reduced.

Abstract: ABSTRACT Apparatus for assembling binary data bits in parallel by groups in variable, selected locations in a shift register for subsequent serial readout.  One or more shift registers are arranged in a matrix of rows and columns of storage cells and addressed along one coordinate while a plurality of data are applied in parallel along the orthogonal.  Selector circuits are controlled to selectively shift a data word to enable the first bit in the word to be stored in any storage position within the addressed coordinate, with each remaining bit in the word stored in a correspondingly contiguous storage position in the matrix.  Bit storage cells of the shift registers are of the set-reset latch type so that once set they cannot be changed by subsequent data bits until the entire array is reset.  This enables the overwriting of successive data bytes.

Abstract: ABSTRACT         PROCESS FOR IMPROVING SOLUBLE COAL YIELD        IN A COAL DEASHING PROCESS    Coal liquefaction products are contacted with a deash-ing solvent and introduced into a first separation zone.    The first separation zone is maintained at an elevated temperature and pressure, determined to maximize the recovery of soluble coal products, to cause said coal liquefaction products to separate into a first light phase and a first heavy phase.  Under -these conditions the heavy phase while still fluid-like in character is substantially non-flowable.  Flowability is returned to the fluid-like heavy phase by the introduction of an additional quantity of deashing solvent into the first separation zone at a location below the interface be-tween the first light and heavy phases or into the heavy phase withdrawal conduit during withdrawal of the first heavy phase and prior to any substantial pressure reduction.  The first heavy phase then is withdrawn from the first separation zone for additional downstream processing without plugging either the withdrawal con-duit or the downstream apparatus.  The first light phase comprising the soluble coal products is withdrawn and recovered in an increased yield to provide a more economical coal deashing process.

Abstract: ABSTRACT OF THE DISCLOSURE:       A detector for monitoring the bath level in an oscilla-tory continuous casting mold oscillates with the latter.  The detector generates signals indicative of the bath level and a control unit interprets the signals and initiates adjustment of the bath level if this is outside of prescribed limits. Since the detector oscillates with the mold, and thus relative to the bath, the distance between the detector and the surface of the bath changes continuously even if the bath level remains constant.  Inasmuch as the detector cannot distinguish between its own movement and that of the bath level, the oscillation of the detector results in the supply of misinformation to the control unit.  In order to correct for the oscillation of the detector, a limit switch is connected with the detector or the control unit and is arranged to be closed by the oscillator at a predetermined point of its stroke.  Thus, the detector will always be at the same position when the limit switch is closed. If the limit switch is connected with the detector, the latter is inoperative as long as the limit switch is open and moni-tors the bath level when the limit switch is closed.  On the other hand, if the limit switch is connected with the control unit, the detector monitors the bath level continuously but the control unit accepts signals from the detector only when the limit switch is closed.
