Abstract: PHASE CONTROL APPARATUS            ABSTRACT OF THE DISCLOSURE         A phase control apparatus is disclosed wherein a pair of transistors are alternately switched by an A.C. signal source.  Each of the transistors is connected in series with an auxiliary thyristor and a primary winding of a pulse transformer to a D.C. power supply.          Each of the auxiliary thyristors is fired by a magnetic phase shifter having an A.C. winding connected between a positive terminal of the D.C. power supply and a gate of the auxiliary thyristor.  Connected to secondary windings of the pair of pulse transformers are gate circuits of a pair of main thyristors to which an A.C. voltage which is substantially in synchronism with the A.C. signal source is applied.

Abstract: ABSTRACT OF THE DISCLOSURE      A modular form is disclosed for enabling an individual unskilled in bricklaying techniques to install professional looking patios, walkways, or to resurface walls and the like. The forms comprise tray-like modules, containing a network of grids which create brick-shaped voids arranged in commonly used brick patterns.  After placing the modules on a suitable surface, bricks are inserted into the voids and a suitable grouping material such as sand and portland cement or masonry cement is applied between the bricks.  The modules insure correct brick pattern spacing and a professional looking final product and permit considerable time savings when compared to conventional methods.  The grids are preferably arranged to form a "basketweave" pattern for ground use and a "running bond" pattern for wall use, but other patterns are also disclosed.  The invention also provides interlocking means for the modules so that uniformity of the pattern is retained in the creation of various sized patios, walkways or brick walls.

Abstract: ABSTRACT OF THE DISCLOSURE This invention describes a low pressure process for the homo- or copolymerisation of olefines containing 2 to 10 carbon atoms in the molecule.  In particular, it des-cribes a polymerisation catalyst formed from a compound of a Group IV, V or VI heavy metal (Periodic Table of Mendeleev) and an organic metal compound of a metal of Group I, II or III; said catalyst being supported on an aluminium compound of the formula AlKX(3? - n)-nOH, where X is a halogen atom or an inorganic oxygenated anion, m is the valency of the individual group X, K is the number of the aluminium atoms and n is a number varying from 0.01 to 3.  As the melt index of the homo and copolymers obtained by the invention can vary over a very wide range, these polymers are suitable for many types of operations.

Abstract: ABSTRACT OF THE DISCLOSURE           Improvements in thermoplastic yarn rebound texturizing method are provided by advancing a plurality of continuous filament yarns at different speeds into a stream of heated fluid advancing longitudinally of the yarns, hurling the yarns toward a foraminous surface by means of the stream of fluid while passing at least part of the stream of fluid through the surface, impinging the advancing yarns on the foraminous surface with sufficient force to induce compression crimps in a filament of at least the faster fed yarn, instantaneously rebounding the yarns from the foraminous surface, and continuously controlling the actual compaction of the yarn as it moves away from the crimping zone.  The rates of advancement of the yarns respective to the fluid stream are such that at least one yarn is introduced into the system at a rate at least twice the rate of the other.           The result is a novel yarn in which the more slowly fed yarn serves as a core and the more rapidly fed yarn serves as a cover or "effect" yarn with its filaments providing rebound textur-ized loops protruding laterally from the core.  The crimped filaments are entangled with one another and the effect yarn is entangled with the core to give the yarn product stability and integrity, permitting it to be processed into fabrics and the like on conventional equip-ment.  An additional slub yarn effect may be achieved by slowing the core yarn feed, thus periodically forming overfed yarn slubs or nodules on the effect yarn product.

Abstract: Abstract of the Disclosure A stepless variable stroke drive particularly suitable for a bicycle transmission has a crank driven input element comprising a carrier housing journaled for rotation on a spindle.  Mounted within the carrier, journaled on individual axles, radially spaced to the spindle, are four planet gears which engage an output sun gear.  Recessed into one side of each planet gear is a concentric channel whose outer circumference is constructed with ratchet teeth and whose inner circumference journals a crank ring having pawls for engaging the ratchet teeth.  The ring also has a follower which engages a cylind-rical cam channel fixed on and adjustable to various eccent-ricities relative to the spindle.  As the carrier housing rotates, the crank ring follower engages the cam channel causing the crank rings to angularly oscillate at an amplitude propor-tional to the cam channel eccentricity.  Sequential intermittent engagement of the crank ring pawls with the planet gear ratchet teeth during a portion of each carrier revolution drives the sun gear at a constant speed which is a multiple of the input speed dependent on the cam eccentricity.  In another embodiment, the crank ring is eliminated and the planet gears each have a follower for engaging the eccentric cam channel.  The carrier housing has slots for the planet gear axles which allow the planet gear to sequentially move to engage and disengage the sun gear for a selected portion of each planet gear's oscil-lation to accomplish a speed increase, decrease or reversal.       Alternate manual and automatic controls are provided for both embodiments to adjust the cam channel eccentricity.
