Abstract: ABSTRACT         A pressure operated hinge for swingably mounting a door on a frame behind their exposed front portions is of three parts involving a box having pressure elements to be mounted within a back-positioned cavity in the door, a swing arm part that carries a rounded, pin-like guide surface pro-vided with at least one contoured slot therein, and a frame mounting plate part that is adapted to be adjustably secured by a set screw and a tongue and groove connection to the swing arm part.  The operating relation between the pressure elements and the guide surface is designed to minimize friction therebetween, and the swing arm is adapted to move into the box to provide a substantially flush positioning when the door is fully closed.

Abstract: ABSTRACT       Corner joints in structures such as furniture incorporating panels of chipboard are provided.  A corner joint is formed using a connecting member cut from an extrusion of constant cruciform cross-section.  Adjacent edges of two panels are secured in respective diagonally opposite channels of four V-section channels defined by the extrusion.  One of the two remaining channels which faces outwardly from the corner is occupied by a filler member.  The longitudinally extending edge faces of the two webs of the cruciform cross-section which extend outwardly may be flush with the adjoining outer surfaces of the panels and the filling member to present the appearance of inlays.  Also the connecting member can be entirely concealed from view from the exterior of the article of furniture.

Abstract: ABSTRACT A supported titanium catalyst component, suit-able for use in the polymerization of alpha-olefins, is produced by treating a supported titanium-containing solid obtained by co-pulverization of a magnesium halide, a tetravalent titanium halide which may also comprise an electron donor compound and/or a halogen compound with an organohalogen compound.  The component is thereafter treated with an organoaluminum compound and an electron donor compound.  The resulting supported titanium catalyst, when employed as a titanium component with an organoaluminum catalyst component results in a catalyst system useful for the polymerization of alpha-olefins.

Abstract: A hydrocarbon conversion-catalyst regeneration process and apparatus is described for converting residual oils and regeneration of catalyst in two separate low and higher temperature regeneration stages stacked one above the other on the same or different vertical axis to provide catalyst at "a temperature above the residual feed psuedo-critical temperature. A CO rich flue gas is recovered from the low temperature regeneration stage and a CO2 rich flue gas is recovered from the higher temperature regeneration stage The temperature of the catalyst mixed with the residual oil feed is sufficient to obtain substantially complete vaporization of the residual oil charge. A special arrangement of apparatus is provided in the lower portion of a riser conversion zone to obtain the intimate vaporization contact between resiqual oil feed and the high temperature catalyst charged to the riser.

Abstract: Abstract:          A-C energy, from an a-c power system, is converted by a phase-controlled SCR rectifier bridge, which is followed by a series-connected filter choke and a shunt-connected filter capacitor, to d-c power for delivery via a d-c bus to a load, such as an inverter and an a-c induction motor driven by the inverter.  When there is a decrease in load demand, for example when the motor speed is to be reduced, fast speed control is obtained by regenerating power back into the a-c power system from the load.  Power flow through the d-c power supply is reversed by means of a switching network, interposed between the filter choke and capacitor, having a pair of reverse SCR's for cross-couplinq the positive and negative lines of the d-c bus.  When the reverse SCR's are fired into conduction, the connections between the filter capacitor and the bridge's output terminals are effectively reversed, thereby facilitating power flow from the load to the a-c power system.

Title: Control mechanism for an integrated brake and  steering system

Abstract: A CONTROL MECHANISM FOR AN INTEGRATED BRAKE AND STEERING SYSTEM                ABSTRACT OF THE DISCLOSURE         A control mechanism through which pressurized fluid from a source is communicated into a brake system and a steering system in response to independent operator brake and steering signals.  The control mechanism has a housing with a first bore and a second bore therein.  A piston located in the first bore separates a first chamber and a second chamber.  A spool valve located in the second bore separates a brake pressure chamber created therein from a series of lands that control the flow of the pressurized fluid through the housing.  When an operator effects a brake application, the piston moves in the first bore and creates a brake pressure in the first chamber.  The brake pressure which is communicated to the brake pressure chamber in the second bore linearly moves the spool valve and allows pressurized fluid to be communicated to the second chamber in the first bore.  The pressurized fluid in the second chamber acts on the piston and provides a power assist to aid in the develop-ment of the brake pressure during a brake application.  When an operator turns the steering wheel of the vehicle, rotary torque is transmitted through an input shaft to a torsion member connected to a pinion which engages a rack in the steering system.  Rotation of the input shaft causes a restriction in the flow of the pressurized fluid from the housing to a piston attached to the rack in the steering gear.  The restricted flow causes a pressure differential to be created across the piston to provide a power assist in moving the rack.  The movement of the rack is transmitted to rotate the spool valve to eliminate the restrictive flow condition and the pressure differential so that the rack is maintained in a position corresponding to the position of the vehicle steering wheel.

Abstract: 201,742 A SYSTEM FOR REMOTELY CONTROLLING A LOAD            Abstract A system adapted to remotely control a trans-former relay (12).  The load switch (36) of a transformer relay (12) is controlled by controlling the direction of current flow in the secondary winding (34).  A switch module (26) is coupled with two wires (28) to the secondary winding (34) of the transformer relay (12) providing a unidirectional current flow above a predetermined threshold in the secondary winding (34) in response to a control signal. The unidirectional current flow may be selectively controlled in either direction or may be only purely unidirectional.  A control module (14) is then coupled to the switch module (26) momentarily producing the control signal in response to an external stimulus.  The switch module (26), the control module (14), or both draw a quiescent current from the secondary winding (34) of the transformer relay (12) when the switch module (26) is not activated.  The quiescent current is of an amount which is less than the predetermined threshold. In one embodiment the voltage and current at the control module (14) are limited to values less than those avail-able at the secondary winding (34) of the transformer relay (12).
