Abstract: A case loader for articles in which the articles are received in a straight line extension from the article conveyor and in which they trip a first sensor when a case load is received, and the cases are directed to a loading station below and beside the article receiving station, the cases themselves tilted to receive the articles from an inclined chute the articles falling down the chute, the chute being arranged to reorient the bottles from a straight line into the rows and columns for the case, the case falling back onto the conveyor when filled and being removed from the case loader by the conveyor chain.

Abstract: A buckle for watch bands comprising three folding members. The members are a clasping member connected to an end of one of the watch bands, a middle plate rotatably connected to the clasping member at one end thereof, and a bottom plate rotatably connected to the other end of the middle plate and connected to one end of the other band. The clasping member and the bottom plate are engaged with each other by an engaging means. A lock member is rotatably supported on the clasping member. A primary hook portion is provided on the lock member, and a secondary hook portion is provided on the bottom plate. The primary hook portion is adapted so as to engage with the secondary hook portion by rotating the lock member when the buckle is in folded state.

Abstract: An extension cone for a cutter for a hydraulic dredge. The cone has spiral helical blades with an opposing helix to the cutter head to force the material forward as the cutter rotates, thus smoothing the bottom and returning any material which was cut and has passed the cutter head back to the suction orifice.

Abstract: A method for polymer coating of chain link fence is disclosed. The thermoplastic polymer is applied in a fluidized bed after the fence is woven. The fence is compressed in the fluidized bed to allow coating of all portions of the chain link.

Abstract: A safety bench pressing apparatus is disclosed which prevents injury from the droppage of barbells. The apparatus includes a three sided frame which functions to catch barbells that are dropped during bench pressing by a person reclining on a standard bench pressing bench. The three sides of the frame include a horizontal member and first and second vertical sections which are respectively joined to the ends of the horizontal member. Each vertical section contains a horizontal support which is vertically positioned above the bench. The horizontal supports catch any barbells which are dropped above the head, neck and chest cavity of a person reclining on the bench during bench pressing. The horizontal members are adjustable in height.

Abstract: An oil well pump which uses a pair of vertical hydraulic pistons to raise a cross beam. The polish rod is secured to the cross beam. At the top of the stroke automatic limit switches reverse the hydraulic fluid flow to allow the polish rod to descend and complete the pumping cycle.

Abstract: An absorption refrigerator in which the refrigerant is miscible in the absorbent at the relatively low absorbing temperature and is at least partly immiscible at elevated temperatures, allowing separation of refrigerant and absorbant in the liquid phase.

Abstract: A gas drying system where the heat energy in the exhaust gas and the dried product is recovered to reduce the energy required to dry additional products.

Abstract: The concentration of the solute in solution in a saturated non-convecting solar pond is greatest at a lower hotter level decreases continuously toward a higher cooler level and is saturated at all levels, thus preventing solute diffusion. In the customary operation of such saturated non-convecting solar ponds, the heat generated by incident radiation is absorbed in a bottom or lower layer. Because of the continuously decreasing density of solute which is near saturation from the lower to the upper layers, there is little salt convection and the pool tends to be further stabilized. Further, by heating due to absorption of the radiation largely at the lower level, a temperature gradient is maintained in which the upper layers remain cool, evaporation and consequent loss of heat is inhibited and the efficiency of the solar pond is improved. It has been discovered that a brine consisting essentially of an appropriate mixture of sodium carbonate (Na.sub.2 CO.sub.3) and sodium bicarbonate (NaHCO.sub.

Abstract: The invention relates to devices which both aerate and chemically alter water delivered by irrigator apparatus such as shower heads. The device is attached to the shower head and includes a first mixing chamber for mixing water and air and a second mixing chamber for mixing the aerated water with a chemical.

Abstract: A process and associated meter devices which will provide accurate and rapid measurement of the quantitites of cement and water in a sample of fresh concrete. A special volumetric flask is filled with a sample of fresh concrete to a known volume. The volumetric flask and its contents are then attached to the hollow body of a shaker meter which forms an extension of the upper part of the volumetric flask. A predetermined volume of special mixing liquid with precisely known density different than water is then added and thoroughly mixed with the concrete sample by shaking. A portion of the resulting cement-water-mixing liquid suspension, or liquor, is then poured off and strained into a vial where its relative density, which is a function of the amount of each constituent present, is determined by a special hydrometer. Another portion of the resulting suspension, or liquor, is filtered through a suitable paper, or other material, so that all cement is removed.

Abstract: A combination paper tape punch and reader having a bi-directional stepping tape transport controlled by a continuously oscillating magnetically activated pawl. A further improvement is a punch interposer geometry allowing for easy removal of the punch and die. A single motor and timing signal is used for both punch and reader tape transports.

Abstract: The invention provides a tank for fluids under pressure, wherein there is a cylindrical body open at both ends and covered with a winding, the bottoms of said tank consisting of caps entering partly and without any clearance the ends of the cylinder, said caps carrying a pad applying onto the ends of the cylinder, a stay-rod located inside the cylinder being made directly integral with both caps through its two ends, a particular use of said tank being connected to an inflatable balloon for use in rescuing skiers.

Abstract: A method for the manufacture of loud speakers of the type comprising in particular a pot for containing a magnet, which method is characterized in that the pot is made in one single piece by pressing and, to this end, a concave blank is formed; it is then pressed to give the blank the shape of a cone, which latter is closed, and the part to be crimped onto the protective cover is then made, the interior diameter measured, the base flattened and the height measured.
