Abstract: A munition in the form of a projectile contains a dart having a body terminating in a front tip and ductile hammer block in the form of a ferrule engaging at least a part of the dart. The dart is formed of sections the diameters of which increase from the back to the front of the dart body, forming support shoulders. A recess in the hammer block has a shape corresponding to the dart body shape received in the hammer block. Hammer block sections form thrust shoulders which engage the corresponding dart support shoulders. When the projectile impacts a target, the thrust shoulders push against the dart support shoulders, causing the ductile hammer block to open and flare out.

Abstract: A munition in the form of a projectile contains a shell having a body terminating in a front tip and a ductile hammer block in the form of a ferrule engaging at least a part of the shell. The shell is formed of sections the diameters of which increase from the back to the front of the shell body, forming support shoulders. A recess in the hammer block has a shape corresponding to the shell body shape received in the hammer block. Hammer block sections form thrust shoulders which engage the corresponding shell support shoulders. When the projectile impacts a target, the thrust shoulders push against the shell support shoulders, causing the ductile hammer block to open and flare out.

Abstract: A munition in the form of a projectile contains a shell engaged in a ferrule constituting a hammer block. The assembly is accommodated in a cylindrical plastic casing having the diameter of the barrel of a weapon for which the munition is intended. The shell has a body portion and a tip at its front end. The body portion has a diameter which does not decrease from the rear toward the front end, and a zone having a locally increased cross-section close to the shell front end. A recess in the hammer block has a shape complementary to the shape of the shell body and constitutes a bearing support for the shell. The region of the hammer block occupied by the shell zone of locally increased cross-section has a cross-section smaller than that of the latter.

Abstract: An improvement is described in the glass cleaning composition a perfume ingredient, a cosurfactant, an alkylolamine methosulfate and water.

Abstract: A mold containing a gasifiable or vaporizable disposable pattern 3, embedded in sand 4 without a binding agent, is fed through its base by a pressurized chamber 6 containing liquid cast metal. The pressure in the chamber 6 is regulated as a function of the surface area/volume ratio of the disposable pattern 3 to prevent the emergence of high-gloss carbon.

Abstract: A projectile adapted to be fired by a fire-arm comprises anchoring means between the outer surface of the tail (3) and the corresponding inner surface of the jacket (7), and the head (2) of the core (1) is connected to the tail by a shoulder (6) and, opposite the tail, the jacket (7) has a rear portion (12) which is of greater thickness than the remainder of the jacket, this rear portion (12) having on the outside undulations (13) adapted to form circular grooves substantially at right-angles to the longitudinal axis of the projectile, a free space (14) being provided between the shoulder (6) and the corresponding part of the jacket (7).

Abstract: Ammunition constituted by a case containing a propulsive charge and a subcalibre projectile for a firearm, the projectile comprising:an internal element (5)an external element (6) andanti-recoil means (7) for the engagement of the internal element (5) in the external element (6), the internal element (5) comprising:a front part (8) with a stopping shape,a rear shank (9) connected to the front part, anda percussive mass (10) at least partly fitted over the rear shank (9), andthe external element (6) being constituted by:an aerodynamically-shaped outer casing (19, 13) covering the front and the side walls of the internal element (5) in order to give the projectile good air-penetration,the anti-recoil engagment means (7) ensuring the connection of the internal element (5) and the external element (6) so that at least initially the external element cannot advance more rapidly than the internal element.

Abstract: A process for the allylation of perhaloalkyl-, perhaloalkoxy- and perhaloalkylthioanilines. A perhaloalkylated-, perhaloalkoxylated- and perhalothioalkylated aniline and an allyl halide in a solvent medium are placed in contact with an effective amount of a metal selected from palladium, copper and nickel.

Abstract: A process for the preparation of N-acyl-N-allylaniline. A solution of diallylaniline or a mixture of monoallyl and diallylaniline is placed in contact with a carboxylic acid halide.

Abstract: A liquid cleansing composition, for use as a hard surface cleaner, comprises(A) a base liquid composition comprising(a) a base composition comprising:(1) an anionic surfactant,(2) a nonionic surfactant,(3) a non-polar grease-removal solvent,(4) a water-soluble detergent builder salt,(5) optionally, a perfume, and(6) optionally, a dye; and(b) water; and(B) an abrasive.The liquid cleansing composition is in the form of a liquid crystalline material of the smectic type. A method of making the liquid cleansing composition comprises sequential addition of the various ingredients.

Abstract: A foundry mould for low pressure moulding of metal parts is constructed of a mould chamber (14) with a bottom surface (17) having an opening (31) through which molten casting metal can ascend. A peripheral pressure chamber (15) surrounds the side walls of the chamber (14) and a suction bell (18, 19) connected to a suction duct (23) covers the top of the mould chamber and pressure chamber. Communicating apertures (20, 21) provide gas flow paths from the mould chamber and pressure chamber to the suction bell. Patterns of gasifiable expanded polystyrene are located in the mould chamber and are supported therein by a masking device, such as a masking shell (28), by means of pattern appendages (26) connected to tubular supporting members (27) of the masking shell. A sleeve (34) is locked to the opening (31) and supports the masking device. Compacted, binderless, sand fills the remaining volume of the mould chamber.

Abstract: Detergent dispenser for providing water-added, concentrated detergent solutions, particularly for replenishing the detergent reservoir of an automatic washing machine, comprising a container equipped internally with a horizontally disposed perforated plate for receiving detergent the plate dividing the container into an upper detergent retaining zone and a lower fluid reservoir zone. In operation, water is continually admitted to the reservoir zone through an inlet port and rises through the plate and detergent mass, thereafter exiting as a concentrated detergent solution via a discharge port positioned above the detergent retaining zone.

Abstract: There is described a heat exchanger with tubes mounted in tubular bearing plates, each plate being provided with passage openings for said tubes, the cross-section area of said openings being larger than the outer cross-section of the tubes proper and a seal being provided between each tube and the tubular bearing plate, which comprises on either side of the medial plane of each plate, lips which bear resiliently and substantially tightly against the outer wall of the tube passing through the opening while retaining said tube some distance away from the edges bounding the opening.
