Abstract: Abstract of the Disclosure In accordance with one embodiment of this invention, a zerovalent chromium compound is introduced onto an activated phosphate-containing support and utilized in conjunction with an organometal cocatalyst, such as a trialkylborane. In accordance with another embodiment of this invention, a phosphate-containing zerogel is formed by removing water from an aluminum phosphate-containing hydrogel by means of azeotropic distillation or washing with a volatile, water miscible organic compound, activated and thereafter zerovalent chromium is incorporated therewith. In other embodiments of this invention, a phosphate-containing support is formed by forming aluminum phosphate from an aluminum alkoxide or from a melt, or by phosphating silica or alumina, or by forming an aluminum phosphate/silica combination. A support thus formed is activated and a zerovalent chromium compound added. The resulting catalysts are capable of giving high melt index, broad molecular weight distribution polymer, which polymer also exhibits other deviations from typical olefin polymers including lower flexural modulus The catalyst is ideally suited for forming olefin polymers such-as ethylene and ethylene copolymers in a slurry system.

Abstract: ABSTRACT OF THE DISCLOSURE A novel combustion control apparatus is herein provided for efficient control of combustion in a process heater with a minimum of components.  The apparatus includes a signal generating device for gene-rating a signal from a condition of a process, e.g. temperature, or pressure in the case of a boiler.  The signal generating device is coupled in para-llel to a resistance, a first electro-responsive device, and a second electro-responsive device.  The first electro-responsive device is adapted to be responsive to a signal of a first characterization.  The second elec-tro-responsive device is adapted to be responsive to a signal of a second characterization.  The resistance is coupled to a first plate of a capaci-tance, the capacitance being adaptable to provide the signal of a first characterization and the signal of a second characterization.  A second plate of the capacitance is coupled in a parallel to the first electro-responsive device and to the second electro-responsive device.  The first electro-responsive device is further coupled to an air control device adap-table to control a flow of combustion air in response to a signal from the first electro-responsive device.  The second electro-responsive device is further coupled to a fuel control device adaptable to control a flow of fuel in response to a signal from the second electro-responsive device. The electro-responsive devices adjust the flow of fuel and combustion air.  The outputs are controlled so as always to provide a fuel-lean mixture during a change in the operating conditions of the process.  As the input signal increases, the fuel rate slowly increases and the air rate slowly decreases.  In the case where the input signal is decreased, the fuel sig-nal is immediately decreased and the air signal is slowly decreased.

Abstract: Abstract of the Disclosure An electrical cable for very high voltage underground power transmission comprises two or more inner conductors     which are twisted together and are supported within the gas-filled void of a hollow extru-ded plastics cable sheath     by means of a plurality of spacers     which are positioned along the length of the cable, each spacer being formed of solid dielectric material with a number of angularly spaced radial webs equal to the number of conductors in the cable and being engaged with the twisted conductors with the webs extending from the cable axis radially outwardly between the conductors into contact with the inner wall of the cable sheath     where the outermost ends of the webs engage with complementarily shaped portions     of the sheath     providing for reduction of the electrical stresses at the spacer ends.  The cable is formed by extrusion of the sheath over the twisted core conductors after insertion of the spacers, and is vacuum corrugated after extrusion, the corrugator being specially formed and operated so as to accommodate the locations whereat the spacer ends engage with and locally deform the extruded sheath.  The plastics sheath can be formed with multiple layers by a multiple extru-sion process, and a metal outer sheath may be formed integrally with the cable and may have corrugations which mate closely with the corrugations of the plastics sheath.

Abstract: ABSTRACT OF THE DISCLOSURE          A method of precisely controlling the temperature of zirconia oxide oxygen sensor is disclosed.  The zirconia oxide oxygen sensor has a zirconia oxide electrolyte which has an oxygen reference side and an oxygen potential measuring side.  Each side of the zirconia oxide electro-lyte has associated therewith an electrode and an electrode lead.  The method of precisely controlling the temperature of this structure has the steps as follows.  An alternating current signal is applied to the zirconia oxide electrolyte by means of the electrode leads and electrodes associated therewith.  As this alternating current signal is applied to the zirconia oxide electrolyte, the electrode leads and electrodes are used to measure the electrical resistance of the zirconia oxide electrolyte.  Using a function of the measured electrical resistance of the zirconia oxide elec-trolyte, the temperature of the zirconia oxide electrolyte is controlled.  This control may be established because there is a direct relationship between the resistance of zirconia oxide electrolyte and temperature.

Abstract: Abstract of the Disclosure A conveyor felt for conveying a paper web through a press section of a paper machine, comprising a support fabric (1) formed by a yarn structure and fibre bat lauer (2) needled to the support fabric at least on one side thereof. The felt is, with the exception of the surface portion (4) of the fibre bat layer facing the web, filled with a filling material (3) so that the felt is completely air impermeable and has a chamois-like surface (2a). A barrier layer is formed in the fibre bat layer for preventing the filling material from penetra-ting into the surface facing the web. The barrier layer is obtained by calendering the surface of the fibre bat layer facing the web so as to make it smooth and compact or by providing in the fibre bat layer a fine-fibered fibre bat layer or a filtering intermediate layer on the side of the surface facing the web. The filling of the felt prevents blowing and rewetting at a conveying speed of up to 1000 m/min although the conveyor felt has a chamois-like surface facing the web.          (Figure 1)

Abstract: MICROWAVE EGG COOKER                 Abstract of the Disclosure A microwave egg cooking utensil having a microwave transparent container for water, a metal tray with at least one depression for holding the egg, and a metal lid. Both the tray and the lid are supported by a lip of the container such that there is a small gap between the outer perimeter edge of the tray and the inner surface of the lid.  The combination of the tray and the lid provides substantial microwave shielding of the interior there defined; the separ-ation of these metal parts prevents arcing therebetween.  It is preferable that the edge of the tray be raised from the lip so that the small gap is not filled with condensation which would minimize the effect of the gap.  The water in the container is heated to boiling by radiation of microwave energy.  The steam heats the tray and the egg cooks by conduc-tion rather than by microwave radiation.

Abstract: APPLICATION OF ROBERT N. SPURR AUTOMATIC CALIBRATION SYSTEM FOR SIGNAL            AMPLIFIER CIRCUITS      ABSTRACT An automatic calibration system for signal amplifier circuits uses a single complex power signal to replace the Formerly used four separate sinewave frequencies and a square wave signal.  In the illustrated embodiment of the invention, the power signal is recorded on a magnetic tape and is played back through reproduce equalizer circuits which apply the reproduced signal to a tracking frequency converter to produce an amplitude measurement of each of the preselected frequency components forming the complex power signal.  The amplitude measurements are referenced to the power signal's actual harmonic content to enable an adjustment of the equalizer circuits to produce a minimum error in the playback signal.  A bandpass phase response measurement is also performed on the reproduced signal by comparing the phase difference between the reproduced signal and a synthesized power signal after the amplitude compensation produced by the amplitude measurements.
