Abstract: The artillery shell (4) is inserted into the rear end (3) of a gun barrel by first placing it in a trough (2) aligned with the barrel.  A swinging arm (6) actuated by a pneumatic piston (11) and cylinder (10) strikes the rear end face of the shell and imparts sufficient momentum to the shell that it is hurled through the wide inlet (3) of the barrel and into the bore (5). The pneumatic cylinder is supplied with compressed air from a pressure vessel (19) with the flow of air being controlled by electromagnetic valves.

Abstract: The measurement signal or a parameter derived from it is compared with a threshold value.  The disturbance time is detected during which the signal or parameter is greater than or less than the threshold value.  The measurement signal is not used to form the measurement value during this period. The disturbance is identified by comparing the measurement signal and characteristic values of the signal or derived parameters in a preceding time interval.  Formation of the measurement values is interrupted during the disturbance period and the measurement interval is extended by the duration of the disturbance period.

Abstract: In order to overcome difficulties which arise when making conventional color charts and color spaces, a torus-shaped spacial structure is used as base body for the arrangement of color tones. The gray tones are located at the outermost jacket area thereof and the clearest colors are located at the inner jacket area thereof. In the inside of the body, the colors extend through all color tone steps from the clearest up to the gray tones. By means of an iterative method for the arranging of color tones in the torus, it is possible not only to discriminate the color tones for the human eye equidistantly, but also to represent the brown colors reliably.

Preferably the alkyl methacrylate is hydroxyethyl methacrylate and the third component phenethyl methacrylate. Cross-linking agents used preferably have their two functional groups differing in reactivity, for example allyl methacrylate.

Abstract: An optical disc drive that employs a velocity feedback loop for detecting the moving velocity (SV20) of an optical pickup, thereby to enable the optical pickup to seek a target recording track of an optical disc. The number of tracks (DT) to the target recording track is calculated on the basis of a signal derived from the optical pickup and a target velocity signal is supplied to the velocity feedback loop in accordance with the calculated result, whereby the moving velocity of the optical pickup can be controlled to become [0] at a timing (time point) at which the optical pickup reaches the target recording track.

Abstract: The present invention relates to a method and an apparatus for removing and recovering organic substances, primarily solvents, from industrial ventilation air contaminated with such substances. The invention is based on the adsorption of solvent in an adsorbent comprising macroporous polymeric particles upon passage of the air through a movable, so-called fluidized bed (2,3) of the polymeric particles. These particles are fed continuously through the bed under the influence of the air and are then fed continuously into a desorption column (8), in which the solvent is desorbed from the adsorbent, stripped with the aid of heated air and drawn off to a cooler (14).

Abstract: In a getter arrangement for providing a getter spot on the wall of an evacuated space, for example an electron tube, the power transfer can be of too short or too long a duration (for example because of positional inaccuracies of the holder containing the getter material or inaccuracies in the shape or composition of the wall). In the first case the intended quality of the getter process is not obtained, in the second case the electron tube may get damaged. A control unit measures the duration of the time interval which starts at the beginning of the power transfer and ends at the instant the getter spot is created. This instant is determined by a detector which detects the getter spot. After this instant the control unit continues the power transfer during a further time interval whose length depends on the first time interval. Consequently, the duration of the power transfer depends on the behaviour of the gettering process, which improves the quality of the gettering process and prevents damage to the tube.
