Title: Explosive projectile
Inventor: SIPPEL ACHIM
IPC: F42B10/44
Filed: 1988-10-27
Abstract: The invention relates to an explosive projectile for generating splinters. 
<??>Known explosive projectiles or warheads are made relatively thick-walled in order to guarantee firing resistance in the rear region. This leads, during the explosive break-up, to a particular splinter size or to a widely varying splinter characteristic between the projectile casing and projectile base. 
<??>To avoid such disadvantages, there is provided, according to the invention, a splinter projectile or warhead which has a projectile base of approximately the same thickness as the projectile casing and which therefore possesses a more uniform splinter characteristic. The reduction in wall thickness in the rear region of the projectile is achieved, at the same time with a reduction of sensitivity to a radial gas-pressure load, in that, in the rear region, the projectile casing 12 is made cylindrical and so as to reach as far as the projectile base 38, the driving band 40 is arranged in direct proximity to the projectile base 38 and the projectile base 38 is curved outwards in a dome-shaped manner.

Abstract: The invention relates to a process for preparing water-thinnable binder compositions based on thermoplastic copolymers for heat-sealable coatings for aluminium foils, and to heat-sealing lacquers formulated with these binders for the packaging industry. The product properties necessary for practical application are achieved in a three-stage process in which a copolymer which consists essentially of alkyl (meth)acrylate and contains minor amounts of glycidyl (meth)acrylate is reacted with an equivalent amount of (meth)acrylic acid and then short side chains of (meth)acrylate and (meth)acrylic acid are polymerised onto it. The water-thinnable heat-sealing lacquers formulated therefrom contain from 20 to 30% by weight of polymer, from 15 to 20% by weight of organic solvent and from 50 to 65% by weight of water.

Abstract: In order to feed two or more yarns having elastic properties in a hosiery knitting machine, so as to constantly secure the same feeding conditions for all yarns, and precisely the same speed and tension, a common feeder roll (10) is provided, with which the yarns are in tangential contact on different peripheral positions, pressed against the roll by an equal number of pressure rolls (11) rolling around the periphery of the feeder roll (10). The revolution speed of the roll, and therefore the yarn feed speed, can be varied by driving the feeder roll (10) by means of a rotary disk (24), the flat surface of which is in revolutionary engagement with a drive wheel (35) which is axially-shiftable, but integral in rotation with the feeder roll (10), in such a way that, by varying the position of the drivewheel (35) in the radial direction of the disk (24), a different revolution speed of the drive wheel (35), and consequently of the feeder roll (10), is obtained.

Abstract: The present invention relates to a multichannel multihop lightwave communication network which allows packet concurrency in the network while avoiding the need for agile optical devices. The network comprises a lightwave communication medium (10) for supporting a plurality of independent user nodes; and a plurality of N network interface units (NIUs) (11). Each NIU is connected to the lightwave medium and one or more separate user nodes and comprises a transmitter section (28-35) and a receiver section (20-27) which are each fixedly assigned to transmit and receive, respectively, over a single channel or a plurality of separate channels to or from other NIUs of the network. In a connectivity pattern for one embodiment of the network, the NIUs are divided into k groups of p k  NIUs such that each NIU of a first group of p k  NIUs is capable of transmitting over the fixedly assigned single channel, or any or all of the p separate channels, to a preferred one or all of the associated p separate NIUs of a second group, etc. based on a generalization of a perfect shuffle pattern. Such technique permits all NIUs of the network to communicate with all other NIUs either via a single hop or via multiple hops where NIUs in subsequent groups of p k  NIUs act as intermediate retransmission units.

Abstract: A deflection circuit (100) generates in a deflection flyback resonant circuit (79) a first flyback voltage (V2) at a horizontal frequency. A switch (Q2) generates in a second resonant circuit (78) a second flyback voltage (V3) at the horizontal frequency having a phase relative to that of the first flyback voltage that is controllable. The first (V2) and second flyback (V3) voltages are summed (Vsum) and applied to a voltage tripler (101) that produces a rectified ultor voltage (V). A control circuit (103) varies the phase of the second flyback voltage (V3) in a negative feedback manner that stabilizes the ultor voltage (U) over a wide range of beam current variations.

Abstract: Disclosed is an aluminum nitride thin film cir­cuit board having an aluminum nitride substrate (1) and a conductive thin film pattern (3, 4) formed on the sub­strate (1). The conductive thin film pattern (3, 4) has a multi-layer structure selected from the group con­sisting of Ti/Ni/Au, Ti/Pd/Au, Ti/Pt/Au, Ni/Au, Cr/Au, and Cr/Cu/Au, and a boundary layer (2) of Aℓ-N-M-O (M is Ti, Ni, or Cr) is formed between the substrate (1) and the conductive thin film pattern (3, 4). Since the boundary layer (2) is formed, bonding properties between the substrate (1) and the conductive thin film pattern (3, 4) are improved. In particular, when the boundary layer (2) contains 0.02 to 30 atomic% of oxygen, a higher bonding strength can be obtained.

Abstract: An automotive driving device for machines and vehicles, comprising a drive motor (1) with a speed infinitely adjustable by means of a setting element (15), a hydraulic torque converter (29) controlled as a function of the speed of the drive motor and of the operating pressure by a control device (31, 32), a manual gearbox (7) situated downstream of the torque converter (29), and a gear-changing device for the manual gearbox (7) with an electronic control circuit and an actuating element (9) for changing gear, is to be configured in such a way that a comfortable gear-changing behaviour is achieved in a simple manner when changing down to a lower gear. For this purpose, the invention proposes that a gear-changing operation from a higher to a lower gear is only carried out if the following gear-change conditions have been fulfilled:
 a) the output speed of the torque converter (29) before the gear-changing operation is below a certain value, which can be set as desired,
 b) before the gear-changing operation, the transmission of the torque converter (29) reaches a certain minimum value brought about by the travelling resistance (working pressure), it being possible to set the said value as desired.

Abstract: A novel method is presented which converts the phase and frequency variations of RF and microwave signals into digital word sequences. By comparison, this phase quantisation is ten times faster, compared with the conventional amplitude quantisation with extremely fast A/D converters. In this process, n parallel shifted signal phases are first obtained from the RF signals by means of a signal phase generator, which are then translated into squarewave oscillations (sequences) in a comparator bank. A subsequent digital sampling of these sequences then supplies the phase variations of the RF signals as digital values at the circuit output. …<IMAGE>…
