Abstract: A gun with two barrels of different calibers wherein both barrels (25,26) have a repeater mechanism, manual or automatic, and wherein the weapon has a barrel-selector mechanism (11, 11A, 11B, 11C, 11D, 11E) which selectively, as desired, brings one barrel into an operative state while at the same time putting the other barrel in an inoperative state. The breech blocks (1, 2) for the respective barrels are joined together via a cam (1 A) on the breech block (1), such that the two breech blocks together constitute a cam mechanism which permits movementofthe other breech block (2) toward and away from the first breech block (1) transversely of the barrels, and that the two breech blocks, during repeater- action of the weapon, move together and in parallel in the longitudinal direction of the barrels. The interconnected breech blocks (1, 2) thus together and synchronously lock the two breech blocks in their forward positions.

Abstract: Procédé de jonction de deux matériaux par enclenchement mécanique d'"éclats" (16) à leur surface de contact. Les éclats, composés d'un des deux matériaux devant être joints ou d'un troisième matériau, sont incrustés dans la surface du premier matériau lorsque celui-ci est formé afin de créer des surfaces qui "surplomblent" le premier matériau (134). Le deuxième matériau (12) est ensuite formé contre les surfaces en surplomb des éclats afin de créer l'enclenchement mécanique. Cette technique est particulièrement utile pour fixer un matériau dissemblable à un matériau polymère ayant des propriétés médiocres d'adhésion et/ou une température élevée de fusion, par exemple des fluoropolymères, comme illustré par la formation par moulage rotatif du manchon intérieur d'un carter de pompe. Dans cette illustration, de petites particules et éclats sont uniformément distribués sur la surface d'un moule enfermé, chauffé de sorte à fondre les particules et entraîner l'adhésion des éclats au moule, et refroidi pour former une couche sur laquelle les éclats font saillie afin d'obtenir l'enclenchement lorsque le carter est formé contre le manchon intérieur. D'autres aspects de l'invention comprennent l'article fabriqué selon le procédé ci-dessus.

Abstract: The invention concerns a speed-control system, method and circuit for carrying out the system, for a brushless direct-current motor using a digital servo loop, specifically an economical and simple means of generating precise information relating to speed of rotation that can also be converted into digital words that can be processed by a microprocessor or by wired components in normal digital switching circuits like counters, gates, adders and subtractors, flip-flops, multipliers, memories, etc. The motor has a permanent-magnet rotor. The voltage at at least one of the stator windings is employed to generate speed information. This is converted by means of a threshold detector into a rectangular wave that can be further processed by the circuit.

Abstract: A time base error corrector comprises a chrominance sub-carrier phase corrector (21) whereby the sub-carrier phase of a video signal is controlled before being written in a buffer memory (12) in such a way that when the video signal is read from the buffer memory (12) on the basis of the reference video signal, the sub-carrier phase of the read video signal may match that of the reference video signal. In the NTSC system (Figure 1), the succeeding line odd/even identification is predicted on the basis of a content odd/even of the preceding field identification and a content odd/even of the preceding field top line identification, and a non-inverted return sub-carrier signal is generated when the succeeding top line identification is determined to be odd but an inverted return sub-carrier signal RSC is generated when it is determined to be even. In the PAL system (Figure 2), the succeeding line odd/even and inversion/non-inversion identifications are predicted to generate four different return sub-carrier signals. The above control is effective when a VTR is servo-controlled in such a way that the reproduced signal is written in the buffer memory (12) in advance of the reference video signal in phase.

Abstract: The invention relates to a process for the transmission in blocks of digital information words with a correction capability. This process consists of transmitting in blocks digital information words, each information word having a length of n1 bits, in which with each sequence of n2-k (n2>k) of consecutive information words are associated k redundancy words of n1 bits each in which, for each order i (1<i<n2), the k bits of order i of the redundancy words are redundancy bits in accordance with a Hamming code (n20k, k). For each set of n2 linked words, each word is transmitted while being protected by an error detecting code. Several sets of linked words can be interlaced. The words of the same order or rank of each set form a group and the groups can be formed by frames.

Title: Explosive cutting means.

IPC: B26F3/00
Filed: 1986-05-27
Abstract: Method of and apparatus for two-wave explosive cutting in which the two-wave form for the shock wave produced by the detonation is achieved by varying the progress of the shock wave to the target in sections normal to the line of cut. This object is achieved, in one embodiment, by supporting a strip of explosive material (24) on a shock wave delay element (21) which spaces the mid-regions of the strip of explosive further from the target than the side edges of said strip. On detonation, the shock waves (25) produced by the side edges (22b, c) of the explosive (24) have less distance to travel through the element (22) than the mid-regions and thereby the classic two shock wave fronts (25a, 25b) situation is obtained in the target.
