Abstract: Abstract of the Disclosure A scaffold device comprising a wheeled frame means includ-ing a front axle assembly and a rear axle assembly which are pivotally interconnected about a horizontal axis whereby either of the axle assemblies may be pivoted or rotated relative to the other.  A first post is pivotally connected at its lower end to the front axle assembly and extends downwardly therefrom.  A telescoping support is pivotally connected at its lower end to the front axle assembly and extends upwardly to a pivotal connec-tion with the first post to permit the first post to be vertically positioned regardless of the attitude of the front axle assembly.          A second post is pivotally secured at its lower end to the rear axle assembly and extends upwardly therefrom.  A telescoping support is pivotally connected at its lower end to the rear axle assembly and is pivotally connected at its upper end to the second post adjacent the upper end thereof to permit the second post to be vertically positioned regardless of the attitude of the rear axle assembly.  A platform is slidably mounted on the first and second posts and extends therebetween.  The ends of the platform are raised and lowered by means of a winch mounted on each of the first and second posts.  A safety catch apparatus is provided for preventing the inadvertent downward vertical move-ment of the platform relative to the posts.  A brake apparatus is provided on each of the rear wheels for preventing the scaffold device from moving.

Abstract: SENSING DEVICE FOR INK FILM THICKNESS IN PRINTING PRESSES        Abstract of the Disclosure A device for detecting changes in ink film thick-ness on the inking rollers of a printing press which includes a transfer wheel rotatable mounted in nipping contact with one of the inking rollers.  A rotatable guage wheel having a slinger ring assembled intermediate its ends and about its periphery defines a measuring surface on one side of the ring for receiving a film of ink from the transfer wheel and the other side defines a reference surface maintained clear of ink by the ring Individual photo-electric sensing members are tangentially associated with the peripheral surface  of both the measuring and reference surfaces and by means of a cooperating circuit including a comparetor, a signal change is given when a difference in ratio occurs between pre-selected signals from these surfaces.

Abstract: ABSTRACT      Coarse, graded coal is fed to a pressurized relatively fixed bed, non-slagging gasifier from which crude gas is recovered.  Fine coal is slurried in an aqueous mixture comprising the discharge from the relatively fixed bed gasifier, which discharge is composed of hydrocarbons, phenolic water and other liquids as major components and additional makeup water, if required, and the slurry is fed to a slagging, pressurized entrained flow gasifier from which additional crude gas is recovered.  The two streams of gas are cleaned and then used to meet a variety of demands, including, but not limited to, gas turbine generation of electric power, manufacture of synthetic natural gas and manufacture of methanol.

Abstract: CIRCUIT FOR COMPACTING DATA     ABSTRACT OF THE INVENTION A circuit for compacting variable length data words into a fixed word length format is disclosed. Each variable length data word and its associated leading O's are separated by a delimiter bit and stored in memory. When the memory is accessed, the output word is loaded in parallel into a first shift register and shifted to strip the leading O's and delimiter bit. Theremaining data bits are then shifted serially into a second shift register. When the second shift register is full, the resultant fixed length data word is latched out. When the first shift register is empty, the next word is loaded in from memory. In this way, a series of variable length data words may be compacted into a series of fixed length words. The circuit is useful for compacting variable length Huffman codes since the boundaries between codes are self evident. This circuit can also be used as a character gener-ator, where the variable length data output comprises the bits required to generate a character image on a raster scanned display.

Abstract: ABSTRACT OF THE DISCLOSURE           A magnetic transducer utilizes the magnetostrictive effect for creating an easy axis of magnetization in the longitudinal axis of a magnetic wire having a high cobalt content by bending said wire, which is then placed in a non-magnetic hollow tube within which the two ends of the wire engage with one another; this tube is placed in the axis of a detection coil and the application of a magnetic field, alternately in one direction and the other in the longitudinal axis of the assembly creates a flux variation due to the magnetization change in the easy axis; the pulses detected have a high amplitude and a low rise time; such a magnetic transducer can be used, more particularly for proximity transducers for elements in translation or in rotation, for example for motors.
