Abstract: ABSTRACT OF THE DISCLOSURE An assembly for mounting a print head to a carriage. The assembly includes a mounting clamp and a lock element in addition to the print head and the carriage.  The print head has at least two mounting studs and a drive element engaging screw.  Both the carriage and the mounting clamp have openings therein through which the studs and the lock element engaging screw pass when effecting the assembly. The mounting clamp also has finger engaging tab members and a ratchet element which includes a resilient free end portion. In addition the stud receiving opening in the mounting clamp includes a ramp structure.  In assembly, the mounting clamp is rotated by applying a torque to the tab members until the mounting studs engage the ramp structure of their respective stud receiving openings.  Thereafter, the lock element engages the screw of the spring head and is tightened thereon.  Both the resilient free end portion and the lock element are provided with ratchet teeth which are in engagement during the tightening operation.  As a result, an audible clicking sound is generated which assures the operator that a tightening operation is taking place.  In this position reverse rotation of the lock element relative to the free end portion is prevented.

Abstract: ABSTRACT OF THE DISCLOSURE          A smoking material in film form comprising a film-forming binder, inorganic filler and a smectite, perticularly a bentonite, which smectite is finely dispersed throughout the material. Fine dispersion is achieved by high energy input during mixing with water, and results in improved ash coherence and greater combustion retardance by the smectite. The materials are characterised by relatively low air porosity.

Abstract: ABSTRACT OF THE DISCLOSURE        A rectangular frame carries a plurality of trans-verse tooth bars pivoted to the frame with each bar carry-ing a plurality of harrow teeth.  A lever arm extends upward-ly from each tooth bar and is connected by a spring to the frame so that an obstruction engaged by any one of the teeth will move the tooth rearwardly against the pressure of the spring which will return the tooth to the original position when the obstruction is passed.  A block is bolted to the frame adjacent each lever and may be rotated to any one of four positions and is engaged by the lever and may be rotated to any one of four positions and is engaged by the lever to control the angle of the lever with the horizontal and hence the the angle of inclination of the teeth within the ground to permit a greater angle than usual when harrowing in trash or soft soil.  The spacing of the teeth in the rearward bar is such that small furrows are formed between these teeth and the teeth of the next two bars will assist in preventing the soil drifting.  Furthermore the weight of the harrow settles the soil and forms a firm seed bed.

Abstract: ABSTRACT OF THE DISCLOSURE     The disclosure describes a slag bath generator operating under pressure and constructed as a vertical and substantially cylindrical shaft, and having a central arching of the base to act as a slag overflow.  Nozzles are directed towards the bath surface and are intended for introduction of the fine-grain fuel and the gasification media.  The direction of the jet of the nozzles disposed in the shaft wall forms an angle of about 35 to 40° with the horizontal, and the nozzles are so distributed that the points of impingement of the jets formed by them on the slag bath surface are situated on a number of concentric circles extend-ing around the axis of the shaft.  With this angle range, there is obtained a maximum acceleration effect on to the surface of the bath which is distributed over the entire surface of the bath.          Moreover, the nozzles are so disposed that the angle formed by the jet impinging on the slag bath surface to the tangential plane of the relevant circle, which tangential plane is vertical at the point of impingement on the surface, is about 10° towards the side remote from the slag outlet.  As a result, a radial force in the direction of the central slag overflow acts on the bath sur-face.

Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus are provided for controlling the movement of a surface traversing apparatus across a member which has an ordered array of openings in its surface.  A multiplicity of automatic move control routines are provided which are respectively operative to move the traversing appa-ratus incrementally over the surface of the member by at least disengaging one of a pair of stepping arms from the member, incrementally moving the stepping arm transversely of the mem-ber and re-engaging the stepping arm with the member.  Each move control routine is operative to advance the traversing apparatus a move increment in one of a multiplicity of dif-ferent directions, with certain of the move routines moving the traversing apparatus parallel to lines or rows of member openings respectively and other move routines moving the appa-ratus diagonally of the lines and rows of member openings. Each move routine senses the relative positioning of the two stepping arms to establish the sequence of operations required to move the traversing apparatus an increment in the appropriate direction.  Each move routine provides for returning a stepping arm to a former position should it be unable to satisfactorily engage the member following a move step.          The move control routines may be stored in a properly programmed digital controller for execution in response to a selection operation which may be either semi-automatic or auto-matic, the latter serving to move the traversing apparatus toward a target member opening in the array by comparing the present location of the apparatus with the target address and selecting the appropriate move routine.  Selection of the move routines is done such as to minimize the number of move incre-ments utilized in attaining the target.

Abstract: TITLE:  VARIABLE VENTURI DOWNDRAFT CARBURETOR             Abstract of the Disclosure A variable venturi downdraft carburetor comprised of an open car-buretor body enclosing an interior first venturi member and coaxial peripheral second venturi member.  The second venturi member is integral with the carbur-etor body and defines a peripheral annular fuel dispensing orifice.  The first venturi member is movable relative to the second venturi member along an upright axis.  The venturi members together define an annular restricted air passage adjacent the fuel dispensing orifice that may be varied in size to increase or decrease the volume and velocity of air passing by the orifice. Fuel is supplied from an annular fuel chamber to the orifice in response to movement of air thereby.  Various air bleed provisions are made to insure proper air-fuel mixing throughout the entire operational range of the engine on which the carburetor is attached.  Provisions are also made to bleed air into the fuel supply as it is being delivered to the mixing chamber in order to premix a charge of air and fuel before it enters the carburetor mixing chamber.
