Abstract: A vacuum lift is formed with an upper housing cover shaped portion having a central opening in which travels a vertically movable piston rod which has a piston disk at its lower end adapted to be selectively positioned to open or close an aperture in a suction disk having an encircling gasket. An enlarged evacuated volume is provided within the housing cover by expanding a plurality of diaphragm sheets into a bellows. The lowermost diaphragm sheet is connected directly to the suction disk and the uppermost diaphragm sheet is connected to and lifted by the piston rod to expand the bellows. The piston disk is formed with an air valve which is positioned by an automatic switching device operable with vertical movement of a draw bar positioned within the hollow piston.

Abstract: Multidirectional source signals which are encoded in two monaural and stereo-compatible transmission channels with predetermined amplitude and phase relations indicative of source directions and adapted to be decoded for formation of more than two loudspeaker presentation signals having source signals corresponding to every source direction appearing in a plurality of such presentation signals, but in differing relative amplitude, are decoded with at least one auxiliary channel. The auxiliary channels have the source signals encoded therein with amplitude and phase relations differently indicative of source directions, and the decode of the two mono and stereo compatible channels is combined with the decode of the auxiliary channels to produce presentation signals with sharpened directionality. Also disclosed are limited-frequency auxiliary channels.

Abstract: A pyrolytic carbon-coated article having improved wear resistance as a result of providing a thin wear-resistant layer just below the outer surface. The layer contains an alloy of pyrolytic carbon and a metal or metalloid carbide and is made by changing the composition in a deposition region without halting deposition so as to create transition regions adjacent the layer which include gradually lesser amounts of the alloying carbide.

Abstract: A cyclonic gas cleaning system is described having an elongated rotary spray header mounted centrally of an elongated housing coextensive therewith. Gas circulates helically upward within the housing while the spray header rotates and sprays a scrubbing fluid into the gas.

Abstract: A dry, particulate composition is prepared. When the dry, particulate composition is reconstituted with a liquid and whipped, the whipped composition is suitable for blending with pourable salad dressings to provide a whipped salad dressing. The composition includes a hard fat and a liquid vegetable oil. Both the hard fat and the liquid vegetable oil are encapsulated within a proteinaceous film.

Abstract: A pneumatic control system is described including a plurality of annunciators in which movable shuttle elements indicate normal and abnormal conditions. In the event an abnormal condition is sensed causing the shuttle element in any of the annunciators to move to the abnormal position, a bias pressure is applied to brake means in the annunciators to lock the position of the shuttle elements which have not moved. Thus, those of the annunciators which are not associated with an abnormal condition continue to indicate the normal condition.

Abstract: Antifertility drug complexes which have enhanced effectiveness and prolonged release of the antifertility drug. The complex includes an antifertility drug, a polybasic acid and a polyvalent metal ion. The antifertility drug is in the form of a basic amine derivative.

Abstract: An apparatus is disclosed for automatically dispensing cups to a continuously moving flight conveyor having openings for receiving the cups and carrying the same continuously forward through a cup-filling station, a cup capping station and a cup discharge station. A cup filling means travels forwardly while filling the cups and a heat sealer means heat seals caps to the cup rims while traveling forwardly with the cups. At the discharge station, the cups are automatically lifted and transferred from openings in the flight conveyor to a take-off means as the cups continuously travel forwardly. The apparatus is also capable of being modified to operate on an intermittent feed basis with the cups stopping at each of the respective stations.

Abstract: Lengths of polymer-coated tubing are continuously produced from steel strip by roll-forming and welding at a fast rate of speed. The welded tubing is sized, cleaned and heated to raise its temperature to that desired for applying a polymeric coating. After coating, the tubing is heated to a desired baking temperature and then cooled. The tubing is unsupported from a location upstream of the coating station until cooled. Elongated endless belts grip the tubing over a longitudinal distance of at least about 2 feet and pull the tubing in a controlled manner to maintain the tubing in precise spatial location throughout its heating, coating and baking.

Abstract: A scanning FM monitor receiver is disclosed which is of the superheterodyne type and is capable of scanning and receiving a plurality of channels on a plurality of frequency bands. The receiver incorporates a phase-locked-loop frequency synthesizing means for generating beating signals for use in tuning specific channels and also incorporates processing means for controlling the frequency synthesizing means and the overall receiver operation. The processing means comprises a central processing unit, keyboard and display interface circuitry, general purpose input and output device and memory means. The receiver includes a keyboard and a display for viewing information during the operation of the receiver.

Abstract: Superalloy structures, such as high temperature components for jet engines and the like, are provided with aluminum-containing diffusion coatings enabling guantum extensions of service life through unique distributions therein of rhodium. The rhodium is prediffused into the alloy structure, and the resultant distribution minimizes aluminum migration into the structure and thus maximizes protective coating performance.

Abstract: A vacuum operated fluid collection bottle including a fluid inlet port and also a vacuum port, with the vacuum port being provided with an improved vacuum shut-off valve provided with an air deflecting baffle. Such baffle is disposed underneath the valve element or valve gate and is spaced therefrom. The purpose for the baffle is to deflect air essentially around the valve gate so that the pressure of onrushing air, due to the imposition of a vacuum condition, will not cause the valve gate to close prematurely. Thus, the valve gate, even though made of lightweight material, will be permitted simply to float upwardly in response to the rise of fluid level within the bottle until an essentially bottle-filled condition is reached, at which point the lightness of the valve gate will be responsive to the reduced pressure area at the vacuum port so as to suck into and tightly seat against the valve seat provided therefor.

Abstract: A scanning FM monitor receiver is disclosed which is of the superheterodyne type and is capable of scanning and receiving a plurality of channels on a plurality of bands. The receiver incorporates a phase-locked-loop frequency synthesizer which eliminates the need for crystals for every channel. The input data that the synthesizer requires to develop the individual preselected frequencies is provided by a random access memory that is programmed by the user for the frequencies desired. Indicator lamps on the receiver illuminate when a channel is being scanned and also provides a visual accuracy check when an operator programs the random access memory with the data codes for producing the various frequencies.
