Abstract: A pump for compressing air, which consists of an inner, fixed cylinder 1 and an outer cylinder 2 which can be displaced around the cylinder 1. Arranged in the inner cylinder 1 is a piston 3 which can be displaced in a reciprocating manner with the outer cylinder 2 and divides the space in the inner cylinder 1 into a first and a second chamber 8, 9. A third chamber 12 in the outer cylinder 2 communicates with the first chamber 8 via one or more openings 17 in the casing of the inner cylinder 1 and with the second chamber 9 via a throughflow duct 10 in the piston 3. The outer cylinder 2 is arranged so as, when displaced in one direction, to press the air in the third chamber 12 into the first chamber 8 and onward, via the throughflow duct 10 of the piston 3, into the second chamber, and, when displaced in the opposite direction, to cause the piston 3 to press the air in the second chamber 9, via a non-return valve 18, out through a nozzle 21. <IMAGE>

Abstract: The present invention concerns a tracer composition which gives a low content of free electrons in the flame and is therefore especially suitable for use together with proximity fuses. The tracer composition has a maximum combustion temperature of 2000 K and includes, in addition to binder and fuel, ammonium perchlorate as oxidizer and, if appropriate, a small amount of an iodine compound, and the iodine compound and the ammonium perchlorate function as an electron-capturing substance in the flame.

Abstract: A motor (1) with belts (2) is coupled to two shafts (3,4) which are common for all the sheets. In each module of sheets are magnet couplings (5-7, 8-10). The sheets (11-13) can carry numerals (14) in series, or letters and different symbols. In each module is a code reader (16-18). The shafts (3,4) move in opposite directions and the sheets ae are rolled on to cylinders (19,20) In front of the sheets is a plastic or glass window (21), and the sheets are illuminated by a light tube (22). Preferably, the sheets are shite, and the numerals, etc. are black. A micro-computer is incorporated in the programming and control arrangement, and the system may be programmed so that a specific magnet coupling, e.g. (5) is connected. This causes a sheet (11) to be moved upwards, with a further magnet coupling (8) being disconnected. At the same time, a further magnet coupling e.g. (6) can be disconnected and another (9) connected, so that a second sheet (12) is moved downwards.

Date May 19, 1988.A method of reversibly compressing a sequence x(k) of information-carrying symbols, preferably digital signals which can assume Q discrete values, K being an index assuming integral number values, and consists in that the sequence x(k) is processed in means (1) to form a residue w(k), whereafter a modulo Q operation is carried out on the residue w(k). The modulo Q reducing sequence w(k) is finally encoded to form a compressed sequence n(k), which contains the same information as the original sequence x(k). In reconstructing the sequence x(k), the compressed sequence n(k) is decoded and subsequently processed in inversion means (5) to form a sequence y(k), on which a modulo Q operation is carried out, whereby the original sequence n(k) is obtained. An apparatus for carrying out the method includes means (1), means (2) for carrying out the modulo Q operations and an encoder (3). For carrying out the reconstruction it further includes a decoder (4), means (5) and means (6) for carrying out the modulo Q operation.

Abstract: In a doppler radar, in order to compensate for the speed of moving clutter, one first establishes during a burst of order (i) the phase variation  phi ri from one period to the next and which is due to clutter in a given range cell. Then, this phase variation  phi ri is memorized and is used during the course of each of the periods of repetition of the next burst to modify the phase of the signal received from the clutter from the same range cell in a maner as to displace its Doppler frequency towards the zero frequencies band, and band which corresponds to the rejection zone of the fixed echoes eliminating filter.

Abstract: In computer-controlled adjustment of grinding machine settings, one single ball screw (8) is operative to move a lower table (5) and an upper table (6), mutually locked together, to a terminal position in which locking engagement is released and the direction of table movement reversed. The tables move together from their starting position, as a result of the friction acting there between, to a predetermined upper-table position in which an engagement means (25a) engages and holds the upper table (6). The lower table (5) then continues to move to a position in which reference points located on the tables are spaced at a predetermined distance apart. The tables are then reconnected mechanically by means of the locking device. This procedure enables the entire grinding cycle to be computer-controlled, including the machine-setup operation. The device which locks the tables together comprises excentric shafts (31) journaled in the upper table and provided with locking shoulders (35) which engage or grip an elongated straight edge mounted on the lower table on mutually opposite sides of the straight edge. Oblique forces liable to jeopardize grinding accuracy can therewith be avoided. The invention also relates to a computer-controlled grinding machine provided with a work head and a center-point tailstock (16, 17) operating in the manner stated.

Abstract: The invention relates to a process for acoustic insulation of the hull of an underwater body with the aim of minimizing sonar echoes from underlying frames and other stiffenings. This is realized by the frames 4 having contact with the hull 1 by way of air-filled high-pressure hoses 3 which are compressed whenever there are increases in pressure. The compression is halted by the frames 4, which by way of stop lugs 2 and 5 come into mechanical contact with the hull 1 once the hoses 3 have been compressed. The insulation is realized in a partly dynamic manner, which means, inter alia, that it can withstand high pressure without strength-related problems. The thus insulated hull is given a configuration such that horizontally incoming sonar signals produce very small echoes. This is realized by the hull having no vertical sides facing the incoming sonar signal. <IMAGE>

Abstract: A method of making a gas permeable material having a diffusive gas permeability at 0.21 atmosphere diffusive driving force in the range of about 0.5x105 cm3/100 square inches/day to about 2x105 cm3/100 square inches/day. The method comprises the step of coating a pattern of spots of a gas impermeable material onto a porous substrate, followed by a step of enlarging the pattern of spots to cover greater than about 95% of the porous substrate such that the gas permeability occurs only through openings between the pattern of spots. The gas impermeable material is preferably a hot melt adhesive and the porous substrate is preferably a nonwoven. The step of enlarging the pattern of spots includes smearing substantially circular spots into oblong spots as the pattern of spots is printed onto the porous substrate until the oblong spots partially overlap. The smearing is achieved by operating a printing screen at a surface speed higher than a draw rate of the porous substrate. Alternatively, the step of enlarging the pattern of spots includes calendering through a fixed gap the porous substrate after the pattern of spots is coated thereon.
