Abstract: An incinerator apparatus consists of a container with an inlet for gaseous or particulate, combustible material together with combustion air, and has an outlet for combustion products, the walls of the container, and possible walls disposed in the interior of the container, being designed for the generation of vortices in the material flowing through the container from the inlet to the outlet. At least the surfaces of the walls facing the inner space of the container include a substance which has the capability to catalyze the oxidation of carbon and carbon compounds in the combustion in the apparatus.

Abstract: A Kenya hive is modified to accept on top thereof at one end portion of the Kenya hive a Langstroth hive. Better wintering of bees in colder climates is thus achieved while retaining the known advantages of the Kenya hive. Modified forward brood frames and frame spacers enable the mounting of the Langstroth hive with stability on this portion of the Kenya hive. Modifications of the rear honey frames and top bars improve the efficiency of the Kenya hive and reduce its manufacturing cost. Other improved constructional features are disclosed.

Abstract: A floating aerator for a body of water includes a motor and deflector cone assembly whose connecting rods are adjustably secured to angle support feet which are stably seated in recesses formed in the top of a float body. The device is efficient and economical to manufacture.

Abstract: A two wheel manually steered and propelled cart for transporting calves and for other uses around a farm is characterized by very sturdy economical construction including two end frames joined by corrugated metal panels. The manipulating handle for the cart has its two side arms pivotally attached to the front frame and releasably engageable with gravity-assisted latches on the rear frame to allow easy lowering and raising of the body of the cart. Two large ground wheels are journaled between the side members of the pivoted handle and parallel side members of a support yoke which is engaged with bearing elements on the front frame.

Abstract: The total weight of material loaded into a floating barge is determined with high accuracy automatically. Human and other error factors are eliminated. Before and after loading, the angle of list of the barge in the port-starboard plane and the angle of trim in the fore-aft plane, together with the distance from the water surface to a fixed overhead structure and the distance from this structure to a fixed point on the barge deck are measured. Using the known barge geometry and the above measurements before and after loading, a computer calculates the change in the volume of water displaced due to loading the barge and by using Archimedes' principle and then calculates the payload introduced into the barge.

Abstract: Entire or partial end wall or side wall sections of a corrugated metal building can be constructed economically with an integrated solar heating panel which can supply forty to sixty percent of winter heating during daylight hours. The solar heating panel or wall section matches and supplements the appearance of adjacent standard wall surfaces and a virtually unnoticeable transition from standard to solar heating wall surfaces is achieved. Heated air can flow by natural convection or with blower assistance through a plenum in the solar heating wall panel to and from connected ducting. A uniquely formed clip provides the proper stand-off spacing between superposed sheets which make up the solar heating panel and the clips also serve to securely join the several corrugated sheets in proper interfitting relationship with the use of strategically placed self-tapping screws and intervening closure strips which maintain solar plenum integrity.

Abstract: For in-circuit and functional testing of loaded printed circuit boards with speed and precision, a vacuum-actuated test fixture utilizes a yielding diaphragm assembly with rigid frame and spring-loaded diaphragm base plate, to distribute downward atmospheric pressure evenly over the entire area of the board without localized stress concentrations. A captive removable diaphragm frame and quick-acting spring-loaded cam latches assure a positive seal around the margin of the diaphragm assembly and along top and bottom edge portions thereof. Ease of assembly and disassembly is promoted. A plug-in vacuum adapter with manual valve provides quick hook-up of the test fixture to a vacuum source. A lower base frame and patchboard assembly allow efficient interfacing of the text fixture with a suitable receiver frame of test apparatus.

The die includes separable sections, at least one of which is heated, and is provided with an elongated spiral molding groove. On each use of the apparatus, a spiral solder section having a length as great as twenty feet is produced.

Abstract: An essentially tubeless heat exchange structure and an attendant controlled evaporative or condensing process is disclosed. A finned heat exchanger body has multiple spaced through passages constructed by locally deforming the fin metal. Each through passage includes multiple terraced liquid traps and coaxial orifices for counter-flowing gas. A liquid supply device and gas pressure relief device is provided for each through passage. The physical construction of the finned heat exchanger body can vary widely depending upon application.

Abstract: A prefabricated metallic open top box with attached top flanges and bottom wall threaded nipple surrounds the tub drain components and excludes insects and mice from the space beneath the tub. Odors are also excluded from this area by the enclosure. The threaded nipple is readily coupled to the tub drain and descending pipe. The use of the enclosure eliminates the need for constructing a form around the tub drain prior to pouring the concrete floor.

Abstract: To prevent leakage of wet concrete passing from a reciprocating pump to a delivery conduit and to prevent clogging of the seal and valve means interposed between the pump outlets and the mouth of the delivery conduit, a floating sleeve is biased by pump system hydraulic pressure into solid engagement with the wear ring which in turn is held in firm sliding contact and sealed engagement with an opposing wear plate at the outlets of the pump structure. The floating sleeve is pressure sealed on opposite sides of a delivery port for pressurized hydraulic fluid to positively exclude concrete from fouling the operation of the sleeve. Concrete grout under pressure entering a void behind the sleeve applies additional pressure to the sleeve to bias the wear ring even in the event of hydraulic pressure loss. The grout within the void prevents the sleeve from ever backing away from the wear ring.

Abstract: A receiver includes an inner frame and outer walls. Between the outer walls and adjacent side of the receiver frame are placed fixed hanger plates provided with straight slots and interior slides having coacting cam slots. The slides are driven by a hand lever and attached torsion shaft with connected slotted linkage having an over-dead-center locked position. An individual test adapter has four sets of dual bearings or rollers on common dry lube sleeves and can rotate oppositely during the camming action to minimize friction. The individual test adapter rollers rest on dwell shoulders of the cam slots and then descend through the straight slots during movement of the slides to produce positive straight-on engagement of test adapter and receiver multiple contacts, such as ball detent contacts with paddle contacts. The slides have elongated linear guide bearings with attached dry lube pads for precision free movement.

Abstract: A high density connector module which may form part of a receiver having a plurality of similar modules is structured in its rows of passages to receive lockingly a like number of tri-paddle contacts, which in turn are capable of receiving sessile conductors including spring clips for anchoring them to an individual test adapter or panel. The tri-paddle contacts at their ends away from the individual test adapter are connected through wire-wrapped posts to a printed circuit board held by fasteners against a seating surface and within a registration notch of the high density module.

Abstract: Comparatively cool fan bypass air in the annular space surrounding the air compressor of a fan jet engine is diverted near the front of the engine into a duct leading to right and left hand aircraft wing leading edge ducts which in turn deliver the bypass air to a wing blowing device to augment wing lift. All of the fan-generated bypass air can be positively forced into the common duct or manifold by operation of a guided flexible metal strip of sufficient length to form a concave helical diverter vane extending for one complete turn in the annular bypass air engine space when activated by a power control mechanism. Fixed coacting guides shape the normally flat metal strip into the proper cross sectional configuration when the strip is driven to its active bypass air diverting position.

Abstract: To facilitate the removal of heavy accumulations of snow from vehicle surfaces, a roughly triangular sweeping head is secured to a manipulating handle and can be reciprocated along the axis of the handle or swung from side-to-side in a wide sweeping arc. Rubber-like blades attached to the three sides of the sweeping head include tapered edges projecting equidistantly beyond the plane in which the sweeping head and handle are located, thereby rendering the device reversible. The construction of the device is such that damage to the finish of the vehicle by its use is precluded. Very little physical effort is required to completely remove large deposits of snow by means of the device.

Abstract: A strong flexible lightweight sling for lifting and propelling a bowling ball avoids the necessity for drilling finger grip openings in the ball and allows any bowler to bowl successfully with any ball. The annular body portion of the sling is adapted to completely surround a bowling ball snugly in a region below the maximum diameter plane of the ball and to have its diameter adjusted for convenient application to the ball and safe lifting and propelling without slippage. Flexible finger grip loops are employed to swing and release the bowling bowl with precision and to accomplish the girth adjustment of the sling body on the ball.

Abstract: A valved compressible state of the art Dacron shunt is sutured to the left atrium and to the descending thoracic aorta. One ferromagnetic and one diamagnetic shunt compression plate is positioned on one side of the shunt with the two plates in opposing relationship. A state of the art electromagnet and synchronizing mechanism exteriorly of the body cyclically, in accordance with the patient's QRS complex, generates a pulsating magnetic field which drives the ferromagnetic plate toward the diamagnetic plate, thereby cyclically compressing the shunt during diastole and giving assistance to the left ventricle of the heart.

Abstract: Shucked whole clams are propelled by suction through a tube having multiple alternating bulbous portions and constrictions. In passing through this tube, each clam is subjected to a repetitive pulsating squeezing or massage action which results in separation or substantial loosening of the belly from the clam meat or tongue. At the outlet end of this delivery tube, each clam is forced through an abrupt elbow and in so doing the clam tongue bends around the acute angular side of the elbow and nearly reverses its direction of travel. This near reversal momentarily reduces the speed of travel of the clam tongue, and at this moment the tongue is subjected to substantial vacuum near the outlet of the elbow by a pair of oblique angular fluid nozzles whose axes cross one above the other to direct their streams toward the opposite side walls of a horizontal product discharge pipe.

Abstract: Newspapers of substantially any thickness are delivered one at a time in succession to customers with the assistance of gravity following the placing of proper coins into the coin control mechanism of the machine and pulling a dispensing lever toward a newspaper delivery position. The dispensing lever is coupled through a linkage with an individual newspaper elevating device which lifts the folded edge of each newspaper above the upper edge of a retaining plate. Immediately after such lifting, the same linkage releases a clamp member adjacent to the top edge of the newspaper so that the paper can free-fall along a slide to a customer pick-up station. Thinner newspapers can be handled in the machine by a friction roller lift mechanism.

Abstract: A connector having a self-locking insulating holding shell for a replaceable spring contact probe is particularly useful in making connections through panels or modules which include a metallic ground plane for electrical noise suppression. Such panels or modules are commonly used in computer interface equipment and elsewhere where a multitude of electrical connections must be established. Following removal of the spring contact probe from the shell, the shell can be separated from the panel or module without need for a tool.
