Abstract: To avoid the problem of instrumental drift encountered when using an open-split interface between a temperature-programmed gas-liquid chromatography column and a mass spectrometer, the inert gas supplied to the open-split interface and the interface itself are heated to a temperature above the maximum temperature attained by the chromatography column during the analysis.

Abstract: It has been found that the active principles of zoapatle are (-)-kaura-9(11),16-dien-19-oic acid, kaurenoic acid and monoginoic acid and that these acids at prescribed dosages may be used for altering the behavior of the reproductive system of a female mammal; such alterations may include inducing menses in adult female primates, synchronizing the estrous cycle in a group of mammals and preventing birth in female mammals, thus acting as a contraceptive.

Abstract: A pumping method, principally for oil, allows the sucker rod to fall under gravity for the first part of the downward stroke, then decelerates the sucker rod to a slow rate of descent, so creating a pause in the sucker rod's motion. Shock-absorbing means are provided to eliminate the impulsive loadings imposed upon the sucker rod at either extremity of its motion in conventional pumping methods. Hydraulically and mechanically-driven apparatus is disclosed for carrying out the method.

Abstract: An orthodontic appliance for counteracting rotational forces acting on a tooth where such forces originate from the action of an arch wire on the surface mounted conventional orthodontic bracket, said arch wire forces being primarily intended for the linear translation of the tooth. Rotational forces are counteracted by means of a lever arm that is rigidly attached to the conventional orthodontic bracket and in contact with the arch wire at a point spaced apart from the junction of the arch wire and the orthodontic bracket. The counteracting forces generated by the lever arm are proportional only to the rotational forces induced in the tooth by the force from the arch wire. The lever arm may also be configured with a shank capable of being inserted in a rectangular hole located in the conventional orthodontic bracket. Such an appliance is capable of being positively locked into the aforementioned rectangular hole by means of a deformable tail section.

Abstract: A pump jack comprises a rocker arm one end of which is fixed to the upper end of a sucker rod. The other limb of the rocker arm has rigidly affixed thereto a downwardly-extending drive support member and a large driven pinion is eccentrically and rotatably mounted at the lower end of this drive support member. The driven pinion is engaged by a chain, which also passes around a driving pinion fixed to the base of the pump jack. This drive arrangement reduces the acceleration and shock loadings imposed upon the sucker rod at the beginning of its upstroke and reduces the size and cost of the gearbox necessary to connect a prime mover to the driving pinion.

Abstract: A method for reducing the sulfur content of coal wherein comminuted coal is contacted with an enrichment culture which contains acid tolerant Thiobacillus species in combination with acid tolerant hetrotrophic microorganisms in an amount effective to act in a symbotic or synergistic manner with the Thiobacillus species. The initial pH of the coal culture combination may be selected so as to enhance the development of a commercially practical rate of sulfur removal.

Abstract: An oxalate oxidase can be extracted from the stems of beet by homogenizing the beet, filtering, centrifuging the filtrate, precipitating the oxalate oxidase containing fraction with acetone, dissolving the precipitate in taurodeoxycholic acid, dialyzing the solution and column chromatography. Unlike prior art oxalate oxidase compositions, the instant composition is relatively insensitive to sodium chloride and is well adapted to rapid and inexpensive oxalate assay in body fluids. The composition is inactive on almost all body fluid components other than oxalate, the only significant interfering component being ascorbate, and this ascorbate is readily removed by treatment with acid ferric chloride prior to the oxalate oxidase assay procedure, the ferric ion being thereafter removed by a cation exchange resin.

Abstract: A housing for air-conditioning apparatus includes an inlet and an outlet. A controlled level of water in the bottom of the housing serves as a reservoir for a rotating disc which flings a curtain of water across the interior of the chamber in the flow path of the air passing from the inlet to the outlet. Three foraminous walls filter and mix the air with one wall upstream of the rotating disc and two downstream.

Abstract: A flexible printing plate is mounted on a print cylinder by first disposing the plate on a porous transparent panel and securing the plate in place by drawing a vacuum on the side of the porous panel opposite the plate. The panel is pivoted to a position where an operator may view the printing side of the plate and adjust the same according to indicia on the panel to insure proper alignment. Next the panel is rotated to a position where the exposed surface of the plate may be brought into contact with a properly aligned print cylinder. Adhesive on the cylinder will bond it to the plate in line contact and after the vacuum is released the free ends of the flexible plate will be drawn around the print cylinder.

Abstract: A cyanoacrylate-based adhesive composition comprises 55-92% by weight of a 2-cyanoacrylate ester, preferably the ethyl ester, from 40-30% by weight of a vinyl chloride/vinyl acetate copolymer and not more than 25% by weight of a plasticizer (the plasticizer may be omitted entirely). The copolymer is preferably a vinyl chloride/vinyl acetate/maleic acid terpolymer. The adhesive compositions have greatly reduced adhesion to skin, not forming strong skin bonds for at least 30 seconds, in contrast to conventional cyanoacrylate adhesive compositions which form, within in about one second bonds strong enough to tear skin.

Abstract: Disclosed is a vaccine which prevents disease caused by Feline leukemia virus (FeLV) and which comprises a protease enzyme-inhibited, cell-free, ostensibly virusfree, in vitro produced feline leukemia neoantigens including FOCMA which evokes an immune response in cats by the appearance of antibodies thereto and a FeLV virion gp70 neoantigen which evokes an immune response in cats by the appearance of antibodies thereto. A novel method for making the vaccine is disclosed also.

Abstract: A process for making symmetrical alkanediols and the bis-ethers thereof by electrochemically coupling the haloalkylethers that are the equivalent of one-half of the symmetrical bis-ether. A symmetrical alkanediol may be obtained from the symmetrical bis-ether. The method significantly increases the yield of alkanediols as for example 1,4-butanediol from electrochemical processes.

Abstract: A signaling device for mounting on the front of a newspaper tube will pivot from a position perpendicular to the axis of the tube to one parallel with the axis of the tube upon the insertion of the newspaper or mail by virtue of the inserted material engaging one end of a pivoting arm which serves as the signaling device.

Abstract: To measure low volumes of gas flow in high-pressure systems a conventional gas meter is incorporated within a high-pressure container. Connections from inside the high-pressure container are connected to a warning system outside the container to alert the operator when too great a volume of gas is flowing through the meter and a restriction of the size of the outlet to the heavy-duty container prevents the damage to the meter which is designed to measure small volumes and is relatively delicate.

Abstract: Method and apparatus for sorting objects exhibiting identifiable dynamic response to vibrational phenomena, such objects including potatoes, onions, tomatoes and other comestibles. The system utilizes an elongate sorting zone incorporating a surface which oscillates at a predetermined frequency and amplitude which varies from a minimum at the input of the zone to a maximum value at the output thereof. The objects to be sorted move along the zone supported from two positions for a coding interval promoting their dynamic reaction with the oscillatory surface. Objects with higher resilience characteristic are rejected from the zone, while those exhibiting a lesser resilience are transported therethrough. The oscillatory surface is dynamically balanced and readily mounted upon field harvesting devices. .[.By adjustment of frequency of the sorting zone oscillatory surfaces, a multi-stage sorting system is made available..].
