Abstract: BASEMENT WATERPROOFING SYSTEM                     Abstract A method of overcoming the problem of water seeping into the basement of a dwelling or other structure includes procedures for treating a hollow basement wall and for treating the footer drainage tile system which extends perimetrically around the basement wall footer.  Wall treat-ment is effected by pumping a hardenable filler material, in fluid form, into the hollow wall to fill and seal the hollow wall portions as the filler material hardens.  The filler material also operates to fill and seal cracks formed in the outer surface of the wall.  Drainage tile system treatment is effected by digging a plurality of holes at spaced locations around the perimeter of the basement wall to expose portions of the footer drainage tile system at these locations, by removing portions of the footer drainage tile system at the locations of the holes, by cleaning the interior of the footer drainage tile system, and by recon-structing the removed portions of the footer drainage tile system to provide each of the reconstructed portions with a clean-out branch having a near-ground-level access.  Open upper ends of the clean-out branches are capped with novel removable cover structures. Lower regions of the holes are filled with porous particulate material to provide reservoirs for receiving and temporarily retaining water.  If the footer drain tile are found to be laid at an unduly high level with respect to the basement floor, selected ones of these tile nearest the main drain conduit are replaced at a lower level and are surrounded by a bed of porous particulate material to provide a reservoir for receiving and temporarily retaining water.  In some instances, a sump, a sump pump and/or a backflow prevention system may be added to improve operation of the footer drainage tile system.

Abstract: ABSTRACT OF THE DISCLOSURE     A prestressed structural member is described in which there is provided in combination a pair of longitudinal elements, a plurality of strut elements, a plurality of diagonal members and a plurality of joint connector means for rigidly interconnecting the strut elements and diagonal elements together and the same to the longitudinal elements.  The longi-tudinal elements are spaced apart and prestressed in compression.  The strut elements are also spaced apart and each strut element extends between the longitudinal elements, and is disposed orthogonally of a line equidistant from each longitudinal element.  The strut elements are also prestressed in compression.  The diagonal members are oriented diagonally in pairs in box sections or bays delimited by the longitudinal and strut elements and with the strut elements form a lattice structure.  The diagonal members are prestressed in tension.  The joint connector means rigidly interconnect adjacent ends of the strut elements and diagonal members in said lattice structure.  The joint connector means are configured to inter-connect the longitudinal and strut elements with the diagonal members in a manner which deliberately provides a predetermined eccentricity of forces carried by each diagonal member relative to the geometrical intersection of axes of the strut and longitudinal elements.

Abstract: ROTOR/SHROUD CLEARANCE CONTROL SYSTEM          Abstract Cooling airflow to the shroud support apparatus is varied in response to both rotor speed and elapsed time above a predetermined level by the selective use and mixture of two air sources at different temperatures. For steady-state operation, each of four different operating modes has its prescribed cooling air delivery mode such that, generally, as the engine speed and cycle temperatures increase, so does that of the cooling air. For tran-sient operation, a timer is employed to sequence the desired cooling air delivery modes in such a manner as to maintain optimum rotor-to-shroud clearances during the transient period.

Abstract: ABSTRACT OF THE DISCLOSURE           An animal trap having first and second similar frames each having jaw forming sides that lie in common plane and ends extending between them to support the jaws.          The ends have a central portion in which the frames are pivotally connected through adjacent ends for rotation about a common axis between set and closed positions.  Outer portions on each side of the central portion extend to the jaws. There is at least one actuator.  The actuator is capable of rapidly and forcefully effecting the rotation.          The actuator has two arms spring-biased at one end so that the other ends, which terminate in rings encircling adjacent ends of both frames on opposite side of the axis, would, if unobstructed, move apart to a distance substantially greater than the length of the frame ends.  A trigger releasably maintains the trap in the set position.  The trigger com-prises a lug formed on one jaw-forming side of the first frame of the trap.  A foot plate is pivotally attached to the lug and extends between the frames.  There is a contact surface on an end of the foot plate.  A catch is formed on the above one jaw forming side.  A lever is pivotally mounted on a side of the second frame and extends, when the trap is in the set position, to engage the catch and the lug adjacent the contact surface of the foot plate end.  Move-ment of the foot plate about its pivotal mount moves the contact surface to force the lever from engagement with the lug thus releasing the trap.  The trap presents no immed-iately visible obstruction to an animal when in the set position and the trigger has good sensitivity.

Abstract: ROTARY ENGINE     ABSTRACT OF THE DISCLOSURE        A rotating single cylinder is mounted upon a pair of hollow rotating shafts and extends upon each side there-of.  A pair of opposed pistons with a simple combustion chamber being defined within the area between the pistons, are mounted for reciprocation within the cylinder.  Each piston is mounted upon an eccentric bearing which in turn may be stationary or rotatable, so that the effective move-ment of the pistons as the cylinder assembly rotates with the rotary shaft, is towards and away from one another with-out the stopping and starting of the pistons at top dead centre and bottom dead centre.  Intake of fuel/air is via a valve at the inner end of one of the rotary shaft sections and exhaust is through a valve at the inner end of the other of said rotary shaft sections.  The exhaust preferably is discharged tangentially of the plane of rotation immediate-ly adjacent the cylinder assembly to avoid the head from the exhaust, affecting the rotary shaft and bearings therefor.          Due to the rotary motion of the pistons and cylinder, with the combustion chamber in the centre, centrifugal inertial forces are reduced relative to a conventional four-stroke engine in which the pistons and cylinders have to decelerate, stop and accelerate in the opposite direction at the upper and lower ends of each stroke.

Abstract: ROBERT B. PITTMAN RONALD OWEN WESCOTT MICHAEL OFFERMAN    HERMAPHPRODITE ELECTRICAL CONNECTOR                    ABSTRACT OF THE DISCLOSURE     An hermaphrodite electrical connector in which the two substantially identical connector parts are adapted to be associated, after they have been located side by side and pointing in the same direction, by a flip-flop type of relative movement, that is to say, one not involving rotation of the connector units around an axis in the direction of telescoping movement of the parts.  When the two connector parts are secured together the engaging contacts are substantially completely enclosed and insulated from adjacent contacts.  The construction is such as to accommodate itself to the reception of a substantial number of contact pairs without adversely affecting the strength of the connector, and to be readily manufacturable in a plurality of patterns through the use of a modular mold con-struction; the use of a plurality of patterns permits the employment in a given piece of equipment of a number of pairs of associatable parts which can only be associated with one another in those predetermined pairs, thus positively preventing the making of incorrect electrical connections.  The parts are designed to facilitate their telescoping connection and to rigidify and strengthen the assembled connec-tor.  The connector construction leads itself to the production of a simple but effective wire-splicer.

Abstract: Abstract of the Disclosure A phase corrected clock signal recovery circuit for multilevel digital signals includes a transition marker generator for generating a narrow width pulse each time a received multilevel digital signal crosses one of the threshold levels between the adjacent logic levels of multilevel signal.  Picket fence-like pulse trains are thus formed, the pulses (transition markers) of which correspond to the threshold crossings of the received digital signal,  The pulse trains are interspersed with spaces or eye intervals which correspond to the absence of any threshold crossings.  Each eye interval addition-ally corresponds  to the time during which each respec-tive bit of digital signal information is transmitted.          The rate of occurrence of the pulse trains is substan-tially equal to the clock frequency of the received digital signal.  A phase error correction circuit is operatively coupled to the output of the transition marker generator and to an electronically tuned bandpass filter capable of adjusting the phase of the pulse trains.  More specifically, the phase error detection circuit includes an up/down counter and adjusts the phase of the clock signal recovered from the pulse trains such that the number of transition markers generated during the high portion of the clock signal equals the number of transition markers generated during the low portion of the clock signal.  Thus, selected transitory edges of the pulses of the recovered clock signal are centered at the middles of the respective eye intervals, that is, at the points in time when each respective bit of multilevel digital signal information occurs.  This phase corrected recovered clock signal is conveniently applied to appro-priate sampling circuitry to enable sampling of the multilevel digital signal at optimum times, that is, at the center of the eye intervals.
