Title: Process for preparing fuel based on rape-seed oil fatty acid methyl esters for self-igniting engines
Inventor: KOMERS KAREL DOC ING CSC
IPC: C10L1/02
Filed: 1992-02-24
Abstract: Rapeseed oil is processed by re-esterification with methanol in the presence of potassium hydroxide as the catalyst. The initial substances are brought to the reaction in the ratio of rapeseed oil:methanol:potassium hydroxide of 1:1.1 to 1.75 of the equivalent : 1.4 to 1.6 % by weight related to rapeseed oil. Re-esterification is performed at a temperature of 20 to 25 degrees C. From the upper layer of the reesterification product methanol is removed by vacuum evaporation at a temperature of 20 to 25 degrees C and the excluded precipitate containing the prevailing part of potassium hydroxide, originally dissolved in the upper layer, is mechanically separated. The methanol vapours are collected in the condenser.

Title: Method of fluidizing a powdered pharmaceutically active substance and inhaler for carrying out the method
Inventor: VILLAX PETER
IPC: A61M16/00
Filed: 1995-01-27
Abstract: Disclosed is a method of fluidizing a powdered pharmaceutically active substance contained in a capsule (4) being placed in an inhalation tube (1) of an inhaler, which method comprises drawing air by a patient through holes at both ends of the capsule (4) and through holes performed in the inhaler inhalation tube (1) beyond the place of the capsule (4) placement inside the inhalation tube (1) admitting air to the tube downstream of the capsule. Within the region of the capsule (4) fitting close to the hole, through which the inhaled air enters the capsule (4) there is generated a zone of lower pressure if compared with pressure in the remaining portion of the capsule (4): This is caused because the amount of air entering the capsule (4) is less than the amount of air leaving the capsule (4). Total clearance of the inhaler capsule (4) inlet holes (7) is less than the total clearance of the inhaler capsule (4) outlet holes (8) and diameter of both the inlet holes (7) and the outlet holes (8) is less than 1 mm.

Title: Apparatus, method and article of manufacture for carrier frequency compensation in an FM radio
Inventor: DINGSOR ANDREW D
IPC: H04B1/40
Filed: 1997-05-05
Abstract: In the present invention, there are disclosed a method, apparatus and article of manufacture for compensating for carrier frequency error. An FM signal is received from an antenna (109) and the received FM signal is provided to a receiver (201). The receiver (201) takes the FM signal at the carrier frequency and outputs a baseband signal. This baseband signal is then processed by a digital signal processor (105), which provides carrier frequency compensation and decoding to produce a data stream that a microprocessor (103) provides to a host device (100). Frequency differences between the FM carrier frequency and the frequency used to demodulate the FM signal can shift the DC bias level of the baseband signal. The digital signal processor (105) compensates for such frequency difference by using a receive compensation value and applying it to each received signal sample. When transmitting, data to be transmitted is provided from the host device (100) to the digital signal processor (105) via the microprocessor (103). The digital signal processor (105) provides encoding and carrier frequency compensation of the data to provide a baseband signal to a transmitter that modulates the baseband signal to produce an FM signal at a desired carrier frequency. Frequency differences between the desired FM carrier frequency and the frequency used to modulate the baseband signal can produce errors in receiver systems. The digital signal processor (105) compensates for such a frequency difference by using a transmit compensation value and applying it to each encoded signal sample.
