Abstract: A process for the pyrolysis of biomass can produce liquid yields ranging as high as 90 % by using appropriate reaction conditions in a reactor capable of rapid heat exchange and short gas residence times. In the process, biomass is introduced into the reactor together with a gas and heat and the pyrolysis process is carried out under specific reaction conditions to produce a pyrolysis liquid containing 10 % to 30 % water. The pyrolysis liquid can be further processed to divide it into a water-rich fraction and a water-poor fraction and these fractions can be further processed to obtain desirable products in commercial quantities including hydroxyacetaldehyde, levoglucosan, acetol, glyoxal or methyl glyoxal. In one embodiment, the process can be used to produce a pyrolysis liquid that is suitable for use as a fuel oil. In another embodiment, the process can be used to produce a pyrolysis liquid that is suitable for use as liquid smoke which can be used to flavour food, particularly meat.

Date Mar. 24, 1988.A method for the rapid and sensitive analysis of heavy metal ores, especially those of gold and uranium, uses high-engery X-ray fluorescence spectroscopy. The invention is of particular interest for the measurement of samples from gold or bodies which typically have concentrations up to 10 ppm by mass. Preferred features include the use of an X-ray tube as a source, the counting of emitted fluorescence photons in energy bands selected to correlate with the characteristic x-ray fluorescence emissions of elements of interest, the excitement of the ore sample by irradiation with high energy bremsstrahlung radiation filtered through tin, the exploitation of polarization in analysis for uranium, the interposition of a platinum-group metal filter between the sample and the detector, and the use of high-purity germanium detectors. Techniques are described for the detection and elimination of inaccuracies due to the presence of certain interfering metals and correction for variations in sample density. Apparatus for use in the method of the invention is also disclosed and claimed.

Abstract: A new method of synthesis of a 2,2-dialkoxy-propane e.g. 2,2-dimethoxy-propane, is described through reaction of a cyclic ketal, e.g. 2,2-dimethyl-(1,3)-dioxolane, with a boric acid alkyl ester, e.g. boric acid trimethyl ester, in the presence of an acidic catalyst. The reaction may be carried out either in liquid or in vapour phase. In the latter case, heating of the thus obtained intermediate mixture to the reflux temperature should follow the catalytic step.

Abstract: A device (10) for spontaneously reporting remotely stored data is coupled to a descrambler (22) in an impulse pay-per-view television system for storing and reporting data pertaining to subject matter descrambled by the descrambler, such as identification of each impulse pay-per-view program that is descrambled. The descrambler (22) receives scrambled television programs over a data link (28) from a central station (24). The reporting device (10) is coupled to the central station (24) by telephone lines (26) for reporting the stored data to the central station. The reporting device (10) includes a memory (12) at the remote location for storing the generated data; and a control unit (14, 18) for causing the stored data to be spontaneously reported in response to the storage of at least a predetermined minumum amount of data, independently of responding to an interrogation signal requesting the report. The control unit (14, 18) includes a clock (18) for indicating elapsed time; and the control unit (14) processes the elapsed time indication to define time slots within which to make the reports, with predetermined time slots for the reporting of the stored data following the storage of at least the predetermined minimum amount of data being assigned by the control means in accordance with stored predetermined criteria. The control unit (14) monitors whether the stored data was successfully reported to the central station (24); and tries again to report the stored data when the stored data was not successfully reported to the central station. Upon trying again the control unit (14) causes the stored data to be reported in a different predetermined time slot than that used for the last previous unsuccessful report.

Abstract: The roller blind, particularly for a picture wall, has a return spring loaded when unwinding, also a locking catch on the winding shaft. This pivots on an axis parallel to the latter and engaging with a fixed stop. On winding in faster than a predetermined speed, centrifugal force causes the catch (9) to swing into a position bearing against the stop and against a locking member (13) rotating with the shaft (5), limiting its angular movement. At lower speeds, gravity causes it to run past the stop (8), which is situated above the axis of rotation (14) of the shaft.

Abstract: The manipulator to guide yarn material at high speeds, particularly monofilaments with a high number of separate elements during the start phase of a drawing or similar process, has a mechanical aid to draw the material through the entry opening. A cutter acts on the yarn fed from the drawing in unit, to cut it into short sections. It also has a drive to power the drawing-in and cutting mechanisms. The drawing-in unit is a rotating blade roller in a narrow housing, and the cutter is a rotating blade roller in a narrow housing. Both rollers can be contained within the same housing. The blade roller is pref. a comb cutter. The drive motor is powered either electrically or by compressed air. The housing can be opened to a slit at the dividing point for the yarn to be laid while moving, and lie over the blade roller of the drawing-in unit so that, as the housing is closed, it is caught by the roller and drawn into the appts. The cut sections are ejected through an outlet.

Abstract: Various meat strips or rolls are cut into slices of equal weight by a machine equipped with a press (14). The meat (36) is placed in the press, where it is compressed axially against a stop. The axial compression forces the meat to conform to the cross-section of the press housing. The meat is then forced from the press at a stepwise motion and cut into slices (20) of identical thickness between each step. Each slice has the same area and thickness, and thus all slices have the same weight.

Abstract: User programs composed of modules for use in automation systems may be created in a cyclic programming process. When solutions are created for complex automation tasks, there is a danger that during the execution of program sequences, individual operands can assume unexpected values in an unforeseen manner, causing error responses in the automation system. The method and programming tool allow data breakpoints to be set up within program logic that in particular has been graphically programmed, in the event of an occurrence of specific conditions. These data breakpoints are set up using a marker in an operand table, which contains selected operands coupled with the type and/or scope of the respective access operation, and using the unique definition of a specific access operation, (achieved by the marker), as a condition for the occurrence of the desired program interruption.
