Abstract: Up to date television programming information along with a commercial is provided for a viewer of television independent of the viewer's television set. Such is accomplished by a radio either AM or FM which broadcasts first and second subcarrier signals carrying respectively a commercial and up to date television program information. The commercial and up to date television program information repeats after given set time periods, the later being updated every one-half hour. A viewer need only operate a specially designed radio receiver at a convenient location anytime he wishes to know which programs are coming up on his television set. The receiver is designed so that it will always play the broadcast commercial before the television program so that the system can be appropriately financed with no cost to the viewer.

Abstract: The nursing dress includes an outer dress portion covering the torso of a woman and having a given color and design. An under dress portion, in turn, covers the torso from the inside upper front margin of the outer dress portion and extends downwardly over the top areas of the breasts to within a short distance of the nipples and is of the same color and design as the outer dress portion. This under dress portion may be detachably secured to the inside of the outer dress portion at the shoulders and side arm areas. An exposing arrangement such as zippers or buttons on the front of the outer dress portion permits an area of the outer dress portion to be removed from in front of the torso to expose the under dress portion and an uncovered area of a breast for nursing a child. Since the under dress portion has the same color and design as the outer dress portion, it blends in with the remaining front of the outer dress portion to camouflage the fact that an area of the outer dress portion has been removed.

Abstract: A surge chamber has an outflow/inflow control fitting on its bottom so as to make maximum use of fluid in the chamber. The fitting itself includes a surge pipe section and outlet pipe section extending downwardly from the bottom of the chamber and having companion flanges. An annular nozzle member is positioned between the flanges and defines a reduced diameter opening. This opening is designed to pass fluid from the chamber to a pipeline to prevent fluid separation of the fluid column in the pipeline to prevent fluid separation of the fluid column in the pipeline should the normally provided pumping system fail. The fitting further includes a core member supporting anti-vortex blades and a deflection plate to minimize agitation of the fluid/air surface in the surge chamber as might otherwise occur during outflow and inflow of fluid.

Abstract: A four-cycle internal combustion engine is provided with apparatus comprising a turbine in the inlet air flow path and an extracting compressor in the exhaust gas path. Where the internal combustion engine is an automobile engine and is operating under normal cruising conditions, the manifold inlet pressure is substantially less than atmospheric pressure and incoming air drives the inlet turbine to in turn drive the compressor. The arrangement is such that the inlet air is isentropically expanded while the exhaust gas back pressure is decreased. As a consequence, the energy of compression is reduced and the overall operating temperature of the internal combustion cycle is lowered with the result that more power is delivered for a given quantity of fuel.

Abstract: A mandrel is provided for insertion in a well pipestring. First and second semi-cylindrical sections, in turn, are arranged to be brought together from opposite sides of the mandrel to surround the mandrel in coaxial relationship. Each of these semi-cylindrical sections has holes supporting wire brushes, the brushes being held secure when the semi-cylindrical sections are fitted about the mandrel. End ring members are received over the opposite ends of the mandrel to engage about the ends of the semi-cylindrical sections and hold them securely together. Appropriate collar members threaded on the ends of the mandrel in turn will hold the ring members axially in place and also serve to connect the mandrel to the pipe string. The mandrel itself has a central bore sufficient to maintain the normal circulation or reverse circulation during a brushing operation and the semi-cylindrical sections holding the brushes can be easily removed and replaced as required.

Abstract: A multiple compartment suitcase defining an interior region has parallel rectangular panels, an interior side wall defined by coextensive spaced apart sides normal to the panels, a rectangular base parallel to a rectangular top and normal to the base. Intermediate the panels, a pad dividing the interior space into two compartments and a pad encompassing skirt is joined to the interior side walls. The skirt has a width greater than the normal distance from the pad extremities to the side wall. The pad is movable from a first position providing approximately similar volume compartments, to a second position in which the pad is substantially flush with the one of the panels to enable nesting of similar, yet smaller suitcases therein.

Abstract: The chassis features left and right lateral frames rotatably supporting at their front and rear ends front and rear wheels. The rear wheels are pivoted for steering. First and second connecting members arranged in a cross and lying in a horizontal plane extend between and are attached to the lateral frames to confine the movements of the lateral frames into predominantly parallel planes. A third connecting member extends horizontally between and is attached to the lateral frames in a position spaced above the horizontal plane so that when the chassis is viewed from the side at the most only two frame mounting points fall on a straight line. Elastic relative movement between the left and right lateral frames is achieved as a result of the inherent elasticity of the connecting members and in addition resilient mountings at the attachment points of the connecting members to the lateral frames.

Abstract: A tamper-proof screw assembly is made up of three basic parts, two of which are coupled together. First, there is provided a screw having a flat head with a center tapped opening and an annular array of teeth formed in its surface surrounding the tapped opening. A second member constitutes a torquing member with a flat bottom and central bore passing completely through the member. An annular array of teeth is formed in the flat bottom in a position to register with the first mentioned annular array of teeth. A third member serves to apply an axial force between the torquing member and the screw head to hold the teeth respectively in engagement with each other so that torque can be transferred to the screw.

Abstract: The axial loading system is used in a tape slitter comprised of first and second arbors in spaced parallel relationship carrying male and female cutting knives for slitting tape. These cutting knives are in the form of a series of uniformly axially spaced discs on the first arbor having their corner peripheries bearing in an axial direction against corresponding female discs on the second arbor. The loading system comprises a combination threaded arrangement at one end of the first arbor with a torque applying tool for rotating the threaded means to thereby adjust the axial force of the male blades against the female blades. The torque applying tool not only enables the rotation to take place but will cease functioning after a given torque has been reached, thereby assuring that a given axial force of the male blades against the female blades will not be exceeded.

Abstract: The icing apparatus comprises an open frame structure for receiving cartons stacked in rows and columns on a pallet. These cartons contain perishable food such as broccoli brought in from the field and are to be treated with liquid ice to preserve their contents. Towards this end, the apparatus includes left and right carriages carrying horizontal rows of liquid ice injecting probes or nozzles. These carriages can move up and down left and right sides of the frame and also the probes themselves can be moved in and out towards and away from cartons on the pallet. By this arrangement, an upper horizontal row of cartons can be simultaneously iced by the horizontal row of probes by simply moving the same into the hand hold openings of the cartons. The carriage structures can then be lowered by the heighth dimension of the cartons and a next horizontal row of cartons simultaneously treated with liquid ice.

Abstract: When conventional honeycomb structures are formed into cylinders, the inner wall made up of the inner edges of the individual honeycombs is circumferentially compressed and the outer wall made up of the outer edges of the honeycombs is circumferentially stretched. As a result, the height of the inner wall increases and the height of the outer wall decreases resulting in a bowing in of the central portion of the cylinder so that the cylinder assumes an hourglass shape. This bowing in can be avoided by corrugating the original ribbon core material in the manufacture of the honeycomb in such a manner that one longitudinal edge of the corrugated ribbon follows a wave form of an amplitude greater than the wave form defining the opposite longitudinal edge.

Abstract: A plug is used in repairing holes in walls made up of first and second dry wall panels on opposite sides of vertical studs. The plug itself comprises a first body member slidable along a shaft to which a second body member is held on one end. A spring normally biases the body members apart but they can be compressed to a compact configuration for easy insertion in an appropriate cut-out surrounding the hole to be repaired. After the plug bodies have been inserted, the one body is released from its locked position so that the spring will expand the bodies apart. The first body will eclipse the inside of the cut-out in the wall panel to be repaired while the second body seats against the rear surface of the second wall panel to hold the first body in place. Finishing plaster can then cover the front surface of the first body to complete the patching.

Abstract: The panel sign includes one post in the case of a "flag" type sign and two posts for a panel sign supported at opposite ends, together with a generally rectangular panel member. Each post constitutes an extruded member having an elongated vertical slot communicating with a hollow interior. The panel has an edge flange of T-shape receivable in the slot for lateral support by the post. An extruded filler element in turn has a forward portion arranged to fill the slot when the element is inserted in the hollow interior of the post. This element is cut to a length corresponding to the position of the lower end of the panel edge flange and the bottom of the post so that when inserted in the post, it serves to finish off the appearance of the post; that is, it renders the remaining slot portions substantially invisible. A small additional filler element is receivable in the top portion of the post to fill a top exposed portion of the slot where the edge flange of the panel falls below the top of the post.

Abstract: The normally provided recirculating pump, jet generating action blower and light in a spa are turned on and off by appropriate pump, jet and light signals. These signals are provided by a radio receiver in turn responsive to different transmitted signals. A battery powered hand-held radio transmitter in turn may be manually operated to generate the different signals and thus enable the recirculating pump, jet action generating blower and light in the spa to be operated from a remote location. The system also contemplates the use of switching valves so that the same recirculating pump for the spa can be remotely controlled for recirculating water in a swimming pool should a user also have a swimming pool on the premises.
