Abstract: BLAST HEAD RIGGING APPARATUS    FOR TANK SIDE CLEANING           Abstract of the Disclosure A portable blast head rigging apparatus is dis-closed which is particularly suited for use in cleaning the sides of large storage tanks.  The rigging employs a travel car having a winch mechanism thereon.  By means of a cable connected to the top of the tank the car crawls up the side of the tank to the top where it is pivoted into a position from which it can travel around the entire circum-ference of the tank.  Once in place the travel car hoists a rigging into position against the tank side suspended from the travel car.  The blast head is then moved up and down within the rigging by operation of the travel car winch mechanism and the travel car is repositioned periodically to permit treatment of the entire tank.

Abstract: ABSTRACT         The present invention is an electrically controlled valve that includes an elongated valve body with an axial passageway disposed along the elongation axis thereof.  The valve body has at least one inlet passageway and at least one outlet passageway in fluid communication with the axial passage-way.  The valve includes structure for establishing a static magnetic field within the valve body and axial passageway. The valve member is mounted within the axial passageway for reciprocation therein to selectively establish fluid communication between the inlet and outlet passageways of the valve body. The valve member has a portion thereof formed of material that is magnetizable.  An electromagnetic device is mounted to the valve body for inducing a magnetic field within the magnetizable portion of the valve member such that the induced magnetic field interacts with the static magnetic field to position the valve member axially.  Control apparatus is provided for regulating the energization of the electromagnetic device to thereby control the axial position of the valve member.  The valve body is a substantially cylindrical member with the axial passageway disposed along its central axis.  The valve member includes a spool portion and first and second magnetizable end portions.  The electromagnetic device is, in the pre-ferred embodiment, a coil which is mounted at each end of the cylindrical valve body into which the first and second magnetizable portions of the valve member extend.  The con-trol apparatus includes electrical control circuit that regulates the magnitude and direction of direct current through the coil.

Abstract: MINI-PROGRAMMABLE CONTROLLER             Abstract of the Disclosure A small, low-cost programmable controller is pro-grammed with both bit-oriented and word-oriented program instructions that are stored in a main memory.  A micro-processor couples each program instruction to a respective interpreter routine of machine instructions stored in an interpreter memory.  Bit-oriented program instructions with a common operation code but different bit-pointer codes are coupled to their own respective interpreter routines.  The program instructions have operation codes and bit pointer codes that are assigned by a program panel, and are then translated by a translator PROM as they are coupled to an interpreter routine.  Operand addresses are read through the translator PROM unchanged.  Error-locating circuitry assists in detecting faulty chips in the main memory as the control program is executed.  The hardware required to execute the control program is minimized, while the translator PROM allows the processor unit to be used with prior program panels.

Abstract: ABSTRACT           Improved method for the treatment of sludge from a water storage retention pond used to store the tailings discharged from a tar sands water extraction process.  The method involves mixing the sludge, prior to its processing, with an effective amount of a bitumen flotation promoter, e.g., an ammonium lignin sulfonate whereby a froth is formed.  The froth is separated and processed.  The use of the promoter increases substantially the recovery of the bitumen from the sludge.

Abstract: ABSTRACT            A composite structural member and a method for its production which are particularly useful when such composite structural member is to have a non-linear shape in its longitudinal axis.  The composite struc-tural member is comprised of a number of "U" shaped elements, flexible in their longitudinal axis, which are arranged in two groups of superposed elements, each group forming a comb-like structure having its leg portions facing each other and being closely engaged and firmly secured together.  The method of production consists of placing a first element in contact with a rigid form having the required shape and successively laying the other element over the first element with their leg portions facing a direction opposite to that of the leg portions of the previously laid element and finally securing all the elements together before the composite structural element is released from the form.

Abstract: ADAPTIVE DEFROST CONTROL SYSTEM              ABSTRACT OF THE DISCLOSURE         A refrigerator includes a compressor, an evaporator fan, a condenser fan and a defrost heater which are controlled by a defrost control system.  The control senses the number and duration of freezer and fresh food compartment openings, the duration of the previous defrost operation, and the total accumulated compressor run time since the previous defrosting operation.  A stored count is decremented by weighting func-tions which are adaptably varied in accordance with the number and duration of compartment door openings and the duration of the previous defrosting operation.  When the stored count is decremented to zero, the defrosting operation may be initiated, unless inhibited.  The defrosting operation is inhibited if the total accumulated compressor run time is less than a predetermined amount.  The control is reset to a point just short of a defrosting operation if a power outage occurs.

Abstract: ABSTRACT OF THE DISCLOSURE:      An insulating girder comprises a pair of stringer boards presenting a rectangular space therebetween and a pair of flange plates closing the upper and lower edges of the space whereby the entire lateral extent of the space is confined.  The flange plates are each configured to present a pair of longitudinally extending U-shaped elements for receiving the edges of the boards and the elements each present a pressure deformable outside leg strip which extends longitudinally along the outer surface of the board whose edge portion is received therein.  A plurality of indentations are formed in each of the leg strips so as to protrude inwardly and penetrate into the outer surface of the board edge portion a sufficient distance to cause the same to resist shearing and other forces that might be exerted on the girder.  Thus, the girder is structurally sound and suitable for load bearing usage.  The method for manufacturing the girder consists essentially of the provision of forming rolls and co-operating embossing rolls for pressing the indentation laterally into the flange as the girder being assembled is moved longitudi-nally.
