Abstract: A multiple language electronic keyboard system is disclosed for generating and modifying musical note information. The system includes a plurality of manually activated switches arranged in a matrix of rows and columns with the switches sufficiently close to allow a single finger of the user to activate a plurality of switches in a single stroke. A decoder detects and distinguishes between a first language and a second language of distinct switch activation patterns. Musical note information is generated by a processor which receives information from the decoder concerning the location of each activated switch and the language detected by the decoder. The versatility of this system is further enhanced by the addition of envelope and tone generators and also by visual display devices. In the preferred embodiment the keyboard is arranged to positionally and operationally emulate a guitar fret board.

Abstract: A cradle for an infant is disclosed which is collapsible and which provides several different rocking motions. The framework of the cradle is comprised of an outer frame with an inner frame suspended therein. The outer frame has an open position and a collapsed position and comprises two hoops connected at a first pair of pivots to pivot between the open and collapsed positions, the lower portions of the hoops serving as rockers. The inner frame comprises two U-shaped portions connected to each other at a second pair of pivots. The inner frame is connected to the outer frame at a third pair of pivots proximate the apexes of the U-shaped portions at opposite upper portions of the hoops equidistant from the pivots of the first pair, so that the inner frame can swing within the outer frame about the third pair of pivots. A collapsible receptacle is supported by the inner frame and oriented for side-to-side swinging motion about its longitudinal axis.

Abstract: In many branches of industry large quantities of small items (e.g., wire components) or assembly components are frequently required, which have a strong tendency towards entangling and which conglomerate in a pile. These components, termed entangled components, can be isolated only with great difficulty when required for processing. This invention provides a device for isolating such entangled components with relative ease. For this purpose, a horizontal disentangling plate (1) is provided on which the entangled components (7) are placed. A vibrating device (2) shakes the disentangling plate (1) in a reciprocal motion in vertical direction, thus enabling the entangled components (7) to become isolated.

Abstract: A physiologic analyzer is disclosed for continuous measurement of a subject's metabolic functions in which signals from ventilatory flow rate sensors and gas analyzers are processed to provide continuous measurement of the subject's ventilatory volume, carbon dioxide production, oxygen consumption, respiratory exchange ratio, and other metabolic functions of interest. An expiratory oxygen concentration sampler is enabled only when oxygen concentration deviates from the inspired value. When enabled, the sampler provides at its output a series of discrete signals proportional to successive instantaneous values of oxygen concentration in expired breath. A similar sampler is used in the processing of the carbon dioxide concentration signals. A respiratory cycle timer measures elapsed time between successive inspirations and provides a breath duration signal which is used for rate computations.

Abstract: Determining saturation vapor pressure of a hydrocarbon mixture by chromatographic analysis of the mixture, recording n-paraffin positions on said analysis establishing n-paraffin bisectors halfway between n-paraffin positions, determining the number of moles of compounds represented between n-paraffin bisectors by assigning the C-number of the n-paraffin between bisectors to all compounds between bisectors, determining the mole fraction of compounds between each pair of n-paraffin bisectors, determining the partial pressure of the compounds between n-paraffin bisectors by assigning to that mole fraction the saturation vapor pressure of the n-paraffin, and adding all partial pressures thus obtained.

Abstract: A locking mechanism for a ladder of the extension type having sections slidable over each other where such locking mechanism is affixed to one section and hooks over a rung of the other section to secure the two sections at the desired height, and where such locking mechanism is withdrawable from the plane of the second section during raising or lowering of this section such that it does not bounce and bump against the rungs of the second section during raising or lowering.

Abstract: A cable derailment responsive apparatus for use in terminating the operation of a cable drive for a chairlift, ski lift, gondola or the like is disclosed. The apparatus includes a spring biasing a portion of the pulley assembly for movement if the cable jumps the sheaves, further includes an electrical circuit having a plug-in connector that is mechanically pulled apart from the remainder of the circuit upon cable derailment to interrupt or deactivate the cable drive. Upon remounting of the cable on the sheave assemblies, the connector can be plugged back into the circuit to permit driving of the cable.

Abstract: A process for transducing acoustical signals, including music, speech, noise, etc. which embodies a method which eliminates the usual discrimination between the frequency spectra of the direct and random incidence acoustical components of the sound being transduced and allows the frequency range of interest to be controlled by adjusting the spacing between the diaphragm or major entry port of an acoustical to electrical transducer and a boundary. The invention requires that the diaphragm or major entry port of the transducer be oriented substantially parallel with and proximate to a boundary.
