Abstract: This invention encompasses novel 2,2-diaryl-3-(1-azabicyclo[2.2.2]oct-2-yl)propionamides and intermediates thereto. These compounds are useful anti-diarrheal agents which possess little or no analgesic activity.
Abstract: A process and apparatus for manufacturing dry, solid molasses of greatly improved storage stability uses thin-layer cooling to ensure that the dried molasses has been cooled to the core. The cooled molasses is then precrushed and pulverized by impact without crushing or significant friction.
Abstract: A collecting device for the collection of excretions from various body openings, both natural and surgical in nature, is disclosed. The collecting device includes an inflatable collar which may be inserted into a body opening prior to inflation, and then be inflated in order to firmly anchor itself within that opening and prevent its inadvertent removal therefrom, or attached to a body opening or appendage. A solid elongated tubular member is heat-sealed to either the inner diameter or outer diameter of the inflatable collar, and forms a continuous channel connecting the inflatable collar to a bag disposed external to the body opening so that body secretions from that opening are collected in the bag in a simple and hygienic manner.
Abstract: Preparation of antiarrhythmic and antifungal (8.alpha.,13a.beta. )-8-carbocyclic/carbocyclic methyl-5,8,13,13a-tetrahydro-2,3,10,11-tetramethoxy-6H-dibenzo[a,g]quinoli zines is disclosed.
Abstract: Method and apparatus for monitoring the vibratory displacements of a diffusing or reflecting solid body which in a preferred application is a turbine blade. A laser source of rectilinearly polarized monochromatic light provides a laser beam which is directed at the solid body. The beam reflected off the body is directed toward a first photocell with a photomultiplier along with part of the incident laser beam. Part of the reflected beam is directed toward a second photocell with a photomultiplier. A Kerr or Pockels cell varies the intensity of the laser beam in response to the output current strength from the second photocell to maintain the lighting of the first photocell constant regardless of the presence of speckle phenomenon. Apertures are arranged in front of the photocells and sufficiently small, e.g. one tenth the diameter of the grains of materials of the solid body, so that the lighting of the first photocell may be considered constant at all points.

Abstract: The above-captioned compounds are produced from optionally substituted benzoin compounds by sequential reactions with trizincbismethylene dibromide, phosphorous trichloride and an appropriately substituted amine. The instant compounds are valuable as pharmacological agents as is evidenced by their anti-microbial, anti-arrhythmic, pepsin-inhibitory and anti-hypertensive activity.
Abstract: In a radar installation for measuring distances by transmitting and receig signal modulated by sequences of pseudo-random bits, generation both of the sequence of pseudo-random bits and of corresponding sequences with which the received radar signal is correlated, is controlled by a variable frequency clock. The frequency of the clock is varied to maximize the peak of the correlation function and the resulting frequency used to indicate the radar-target distance.

Abstract: A fastening device for securing articles together, the device including releasably connected male and female components. The male component comprises a pin and the female component comprises a retaining insert positioned in a housing for releasably clamping the pin. When joined, the pin can not be separated from the retainer except by a special tool. The insert is of magnetic material, and an actuating tool including an electromagnet is employed to actuate the insert to permit removal of the pin. The housed insert is attached to a tag, with the tag being attached to the article which is to be sold. The tag houses an electrical circuit which activates an alarm if the tag is not properly removed at the checkout point by means of the special tool.
Abstract: An electric receptacle for ordinary household or trade size junction boxes having a complete ground fault circuit interrupter incorporated in the receptacle, including electronic components to detect a ground fault on the load side of such receptacle, and a coil and trip mechanism which is actuated when a ground fault is detected. A number of the components are utilized in this invention in ways that enable them to perform multiple functions eliminating the need for separate components and the space they would require, thereby making it possible to install a complete ground fault circuit interrupter in a smaller space within a receptacle.
