Abstract: A vial holding a material such as an organic liquid-containing biological specimen is received in the receptor of a holder assembly, the assembly further including a centrifugal valve. The holder is mounted on a rotor in a centrifugal vacuum concentrator and the specimen is then subjected to a treatment such as drying in the vacuum chamber. Vapor from the drying vents into the concentrator vacuum chamber, the centrifugal valve which is a normally closed component opens due to imposition thereon of centrifugal force created during and attending rotor speed above a certain RPM. At completion of the treatment and before the rotor falls from its certain RPM, a dried material protective gas blanket can be flowed into the vial, the valve closing to seal the vial and protected contents when RPM of the rotor falls below the certain RPM.

Abstract: A golf swing practicing article which is shorter in overall length than an ordinary golf club and substantially symmetrical around a center axis of a shaft body includes a grip member disposed at first end section of the shaft body and a weight member at an opposite second shaft body end section, the weight member increasing the mass at the said second end section, the weight member occupying 40 to 60% of said overall length. The weight member can have a tapered portion and a receiving portion for reception and removal of weights so as to vary the weight of the weight section, the weights being cylindrical members of different sizes and such that certain of same fit inside others of the weights.

Abstract: A lens barrel unit for a zoom lens camera which is more compact in the axial optical direction in the retracted state because the lens group moving means and linear movement guiding means are juxtaposed along the optical axis. The lens barrel unit also has a reduced outer diameter due to a reduction in the need for a separate outer helicoid portion of the moving means and elimination of guiding grooves on the inside of the fixed barrel unit.

The strengthening is provided with a continuous frame that encircles coil springs over a major expanse of the central area, this frame being connected to first and last transverse rows of coils in the central area and extra central area transverse coil rows next adjacent the said first and last rows. The frame also connected to adjacently paired longitudinally arranged coils springs in the central area at both sides of the spring structure. High carbon steel of six or nine gauge is used for the frame.

Abstract: Acid digestion of liquid specimens which are to be subsequently analyzed by spectroscopy to identify recoverable or dissolved metals is effected in an open digestion operation in apparatus which includes inclined, vertically spaced saddles on which specimen containing glass jars are supported in corresponding inclined orientation so that a surface of the specimens in the jars is overlaid by the wall of the jar and the jar opening is remote from the specimen, this arrangement allowing that the vessel wall facing the specimen surface, during digestion, will serve as a condensing surface for specimen vapors evolved incident digestion.

Abstract: A turn conveyor system includes a plurality of friction-reducing members disposed along at least the inner edge of the belt to minimize the friction between the belt and the conveyor frame. The members are formed, in whole or in part, from a plastic material having a coefficient of friction of less then 0.2 and may advantageously include raised vee-shaped portions adapted to remove debris from between the belt and the frame.

Abstract: A method for mechanically detaching the meat from the bodies of slaughtered poultry in the form of fillets is performed with a starting product in the shape of a so called "front-half", i.e. a body portion obtained by a cross-section made obliquely through the poultry body. From this body portion the pelvis has been severed together with the legs, and by a further step the wings have been severed. The treatment in individual processing steps, the performance of which is limited to very narrowly restricted working areas by means of tools which can thus be adapted without compromise to the anatomically conditioned circumstances. Moreover, the sequence of the processing steps is selected such that the increasing destabilization of the poultry body is controlled with each processing step so that the respective subsequent working steps are influenced in a minimum manner possible. The result is a high yield in fillet meat of excellent quality.

Abstract: Amino acid-containing specimens are hydrolyzed with a method and in a hydrolysis unit by which a specimen holder having an upper face side against which a cover can be tightly engaged to seal compartments formed in the holder and define a sample chamber in which the specimens are received and hydrolyzed. The holder and cover are housed in a sealable casing, and a heating device is provided to apply heat to the specimens while same are in contact with a hydrolyzing agent, this being done while the casing is sealed from the ambient atmosphere and the holder compartments in turn sealed from the casing enclosed space. The unit embodies a device to impose vacuum on the casing interior during the hydrolysis cycle, or to fill the casing enclosed space with an inert gas for cooling at the end of hydrolysis.

Abstract: Separation of oil from an aqueous condensate is effected by feeding the condensate into the headspace of a liquid pool containig separation tank so that a layer of oil will settle on top of water in the pool. An oil-receiver tank above the separation tank and connected thereto by a vertical pipe, also has a liquid pool therein above which a head space at sub-atmospheric pressure exists. Oil in the layer is accessed with a lower entry to the vertical pipe submerged below the separation tank liquid level and ascends into the pipe and upwardly to the oil-receiver tank, the oil ascent being accompanied by descent of water from the liquid pool in the oil-receiver tank. When the oil-receiver tank and an upper section of the vertical pipe are filled with oil only, the oil-containing tank can be drained. Separation operation can resume following reestablishment of the liquid pool in the oil-receiver by inletting a quantity of clean water thereto.

Abstract: Flap folding plates are provided for use with a carton taping machine, the plates normally being disposed in upright orientation and maintained such by bias applied thereto. Further the plates are arranged so that the top corner structure at the sides of the carton strike the plates to cause the plates to pivot rearwardly in folding movement against the carton side flaps thereby absorbing at the said corner structures the force that might otherwise be transmitted to the front edges of the upright side flaps which could result in tearing or ripping of the side flaps where said flaps are joined to associated side walls.

Abstract: Pull tabs are applied to the two ends of the sealing courses of pressure sensitive tape applied to rectangular shipping cartons. A masking material is applied to the pressure sensitive tape during the taping operation so that the masking material will be adhered to a part of the sealing tape as a pull tab means which is applied to the rear wall of the carton being sealed and a part will be left on the tape stock to provide a pull tab means on the front wall of the carton to be next taped from the tape stock. An apparatus for forming these pull tab means also is provided.

Abstract: A machine is provided for applying vertical tape courses to the ends of cartons. Cartridges carrying taping members are stroked downwardly to tape the cartons. Return or upwardly directed travel of the cartridges is either delayed while a taped carton is off-feeding from the machine or the taping arms and cutter in the cartridge are retracted to allow the cartridge to be immediately returned upwardly following taping. This precludes cartridge travel interfering with carton off-feed or carton entry to the taping station.

Abstract: A plow for a motor grader is provided with forwardly pivotable panel members at the two ends of the moldboard so the plow can retain and carry forward removed grade debris without leaving significant windrow residue. The plow also can with suitable forward and backward tilting thereof and panel member extension be used to cut roadways with water run-off inclines or gullies with inclined side walls at the same time.

Abstract: Perimeter seals are applied to cartons to seal them in courses which encircle a carton wall at which the transverse edges of infolded carton closure flaps are disposed. Such perimeter seals create a seal of the carton interior to prevent access thereto by dust in the atmosphere, moisture, etc. Apparatus for applying the seals includes devices to apply tape around the carton wall and wipe that applied tape onto perimeter areas of the encircled wall as well as marginal areas of the four walls adjacent and orthogonal thereto.

Abstract: Machine for taping cartons of shorter height ranges and taller height ranges. One upper taping cartridge is used for the shorter height cartons, whereas, at that time the taping arms of a lower cartridge are retracted. When a taller height carton is to be taped, the lower cartridge arms are released for taping purposes and they with the upper cartridge are used to tape the taller height carton.
