Patent NL-7505440-A (NL)
Title: Transducer electrical pulse output correction - using impulse generator to provide correction pulses which are gated with transducer pulses
IPC: G01F15/02
Filed: 1975-05-07
Abstract: The method is used for correcting the output signal of a transducer which generates an output signal in the form of a pulse train, the repetition frequency of which represents the physical quantity being measured and in which the frequency is directly proportional to the physical variable over the working range of the instrument. Because of inherent errors or characteristics of the transducer the characteristic, if extrapolated back to zero, does not pass through the origin so that a correction frequency can be superimposed upon the actual measured frequency to obtain a corrected value on a line passing through the original. In order to obtain an accurate correction over the whole working range of the transducer, no correction pulse is superimposed unless there has first been a transducer pulse.

Title: Treating tobacco to reduce nicotine content - by treating moist tobacco with air contg. ozone
IPC: A24B15/28
Filed: 1977-09-07
Abstract: Prodn. of tobacco low in nicotine or not contg. nicotine comprises treating moistened tobacco with air contg. ozone.

Raw tobacco sheets (10kg) contg. 10% moisture and 1.5% nicotine are spread in a container and treated with steam for 5 mins. after which its temp. is about 90 degrees C and the moisture content is 30%. After the steam treatment, dry air contg. 30g/Nm3 of ozone is passed into the vessel at ambient temp. for 2 hrs. During the air treatment, the tobacco temp. gradually falls to ambient temp. and the moisture content to about 18%. The treated tobacco is dried to a 10% moisture content. The nicotine content is 0.4%. In the other example ammonia gas is used to adjust the pH to about 9. The nicotine content of the treated tobacco is 0.06%.

Patent NL-9301551-A (NL)
IPC: E05D15/24
Filed: 1993-09-08
Abstract: The invention relates to a panel for so-called sectional doors, in which a number of panels are hinged together by means of hinge parts which form part of the panel. Each panel consists of an elongated body part, which is formed by two side plates (2,2';30,30') lying a distance apart and along the long narrow sides contains the hinge parts (3,4) for forming the hinged connection. One hinge part (3) contains an arc-shaped nose, the arc-shaped outside wall (12) of which connects virtually directly to one side wall (8) of the body part, and the inside wall (13) running concentrically herewith merges through an acute angle into the other side wall (7) of the body part. The other hinge part (4) has a supporting part lying near one side wall (7') of the body part and bearing an essentially cylindrical thickened part (14), and a concentric wall (17) running at a distance therefrom which with the thickened part leaves a space free for the accommodation of the nose of the other hinge part of an adjacent panel. This concentric wall extends from the foot of the supporting part to the other side wall (8') of the body part and merges through an acute angle into said wall. Through this shape of the hinge parts, a hinged connection which is safe for fingers is obtained between the panels. The invention also relates to a section hinge consisting of two section parts, the shape of which corresponds essentially to the above-described hinge parts. <IMAGE>
