IPC: A23L27/12
Filed: 1986-06-17
Abstract: The present invention is a process for the production of 
citrus flavor and aroma compositions comprising the steps of: 
a) contacting organic citrus flavor and aroma compounds with 
a solvent gas having a temperature between its critical 
temperature and about 100°C (212°F), and having a reduced 
pressure between about 0.56 and about 1.31, to extract flavor 
and aroma compounds the majority of which have a molecular 
weight less than or equal to that of limonene; b) separating 
the solvent gas and dissolved compounds from the remaining 
undissolved compounds; and c) separating the dissolved 
compounds from the solvent gas. This process produces an 
extract which is enriched in the desirable lower molecular 
weight flavor and aroma compounds and decreased in con­
centraton in the undesirable higher molecular weight flavor 
and aroma compounds which could impart off-flavors. The 
invention further comprises the resulting flavor and aroma 
compositions, as well as citrus juice and citrus beverages 
containing these resulting compositions.

Title: Computer controlled lightning system with distributed processing
IPC: H05B37/02
Filed: 1987-04-28
Abstract: A stage lighting system has a plurality of automated lamp units which can vary the parameters of a light beam for pan, tilt, brightness, intensity and size. A control console is connected to each of the lamp units via a data link. Each of the lamp units includes a microprocessor and a memory. Control programs for driving each of the lamp parameters are stored in the memory and are executed by the lamp microprocessor. The console includes a microprocessor as well as memory. Commands are input through the console to change the effect produced by the lighting system. Each of these changes is directed to all of the lamp units. Each lamp unit responds individually and independently to change the light parameters based upon its own operating programs and the data condition of the lamp at the time that the change was made. Each of the lamps further stores a unique lamp cue which corresponds to a system cue that is stored in the memory of the console. When a new system cue is selected at the console, this system cue is directed to each of the lamp units which then recall their independent corresponding lamp cues and set the lighting parameters of each individual lamp. The transmission of numbered cues and change conditions substantially reduces the amount of data that must be transmitted through the data link. Additional lamp units can be easily added to the system without adding to the workload of the central processor or the data that must be transmitted through the data link.

Title: Test strip for the analytical determination of a substance in a liquid sample
IPC: G01N33/52
Filed: 1989-07-12
Abstract: Multilayer test strip for an analytic determination of a component in a fluid sample, in particular for the diagnosis of illnesses. Located on a base layer (2) are a sample receiving region (4) and an evaluation region (6) which are connected to one another by a fluid transporting section (8, 9). An optically detectable change that is characteristic for the analysis takes place in a signal forming layer (11) arranged in the evaluation region (6). In order in the case of such a test strip to create conditions for the colour forming reaction that are defined in terms of longitudinal transport, the signal forming layer (11) is in fluid contact in the evaluation region with a fluid transporting layer (9b) in such a way that the fluid is exchanged perpendicular to the plane of the base layer (2) between the two layers. In this process, the fluid transporting rate in the fluid transporting layer (9b) and the temporal start of the signal forming reaction in the signal forming layer (11) are matched to one another in such a way that the signal forming reaction does not take place until essentially after the propagation of the fluid in the fluid transporting layer (9b). <IMAGE>
