Abstract: A fluorescent lamp system including a pair of fluores-cent lamp socket bars, a pair of ballast transformers, and a wiring harness.  Each lamp socket bar consists of a sandwich of a molded plastic plate which holds the lamp socket contacts and the wiring connector pins, and a printed circuit wiring plate which makes electrical contact with the socket contacts and connector pins through mechanical pressure contact, and which wiring plate contains the circuit wiring excepting for the interconnections with the ballast transformers, such inter-connections being effected either by means of a wiring harness having plug connectors which pluggingly connect to pins on the lamp socket bar and to the ballast transformers or by quick-wire connections from the ballast transformers them-selves.  If a cable harness is used, the ballasts are also pluggably engageable with the fluorescent lamp socket bars.          Assembly of a working fluorescent lamp troffer structure is drastically simplified and accomplished rapidly by securing two of the lamp socket bars within the troffer, plugging the ballast transformers into the socket bar and securing the transformers mechanically to the troffer, and plugging the cable harness into the ballast transformers and lamp socket bars, or alternatively, by quick-wiring the ballasts to the socket bars.

Abstract: Abstract of the Disclosure In one embodiment of this invention a surface silicated alumina composition, as opposed to conventional silica alumina, is provided. Such composition may also be fluorided and/or phosphated or phosphited. The resulting compositions are broadly useful but are of particular applicability as supports for chromium olefin polymerization catalysts. In another aspect alumina is fluorided and used with hexavalent chromium catalyst and a co-catalyst or in the alternative with an organochromium catalyst. If desired the support in this embodiment can also be phosphated or phosphited. In another embodiment, aluminum phosphate is formed in the pores of alumina. In contrast with alumina catalyst supports of the prior art, the supports of this invention allow for the production of olefin polymers at high rates of productivity. Also novel high density ultrahigh molecular weight polymers are produced.

Abstract: CONTROL FOR BUMPLESS TRANSFER OF AN AC MOTOR BETWEEN A SOLID-STATE INVERTER AND A SUPPLY MAINS             ABSTRACT OF THE DISCLOSURE     A power conditioner having a source and load converter each using a phase-locked loop to control their respective converter firings achieves synchronization with a supply mains by determining the phase error between supply mains and motor voltages by obtaining the instantaneous difference between the output signals of the source and load phase locked loops.  This phase error is passed through a simple gain and summed with a speed regulator setpoint, which now becomes an inverter frequency regulator with the nominal setpoint being the supply mains frequency. The voltage amplitude error between the supply mains and the motor is obtained by comparing the absolute value of the source voltage with the properly scaled absolute value of the integrated motor voltage and this error signal is input to the flux regulator in a synchronous or induction motor controller in place of the normal input when not synchronizing.

Abstract: ABSTRACT OF THE DISCLOSURE          The invention relates to a method and apparatus for forming a multi-material continuous elastomeric strip, such as a tire tread slab for pneumatic tires.  The apparatus comprises a plurality of extrusion means for advancing separate elastomeric materials under pressure through separate flow chambers, a preform die through which the flow chambers converge together  to a common junction within the preform die. From the common junction, the multi-material flowstream flows through a preform die exit chamber on to a final die.  The configuration of the preform die exit chamber permits the plurality of materials to adhere to each other to establish a material boundary location within the elastomeric strip prior to final shaping in a final chamber formed between a roller and a final die confronting and converging against the rotating roller upon which the elastomeric strip is deposited in the form of a tire tread slab.  The placement of the common junction upstream of the final die also aids in allowing the operator to control the location of the material boundary within the extruded strip by controlling pressure or extrusion rate of the different materials within their individual flowpaths.

Abstract: Abstract of the Disclosure Bulldozer Blade Mounting and Stabilizing Arrangement Mounting arrangements are required to mount and stabilize a bulldozer blade on a vehicle when it is desirable to both angle and tilt the bulldozer blade relative to the vehicle.  During the angling and tilting of the bulldozer blade, it is desirable to control the pitch of the blade without inducing unnecessary stresses in the mounting arrangement or high cylinder pressures in the angle cylinders.  The present mounting arrangement includes a bracket apparatus which is utilized to allow normal pitching of the bulldozer blade but limit any abnormal pitching thereof during tilting and/or angling thereof.  The bracket apparatus utilizes a first bracket assembly secured to a mounting frame and having a transverse slot defined therein.  The bracket apparatus further includes a second bracket assembly secured to a rear central portion of the bulldozer blade and has a pin assembly secured thereto and disposed in the transverse slot.  The pin assembly being disposed in the slot merely follows the slot during normal tilting and angling of the bulldozer blade but limits the degree of pitch whenever the bulldozer blade tries to abnormally pitch.  This arrangement is simple in construction and is readily retrofitted to current mounting arrangements.  Furthermore, it provides a positive pitch control of the bulldozer blade relative to the mounting frame without inducing any high stresses in the mounting frame and/or high pressures in the angling cylinders.
