IPC: F42C1/06
Filed: 1970-01-20
Abstract: 1297872 Projectile fuzes SNIA VISCOSA SOC NAZIONALE INDUSTRIA APPLICAZIONI VISCOSA SpA 20 Jan 1970 [3 Feb 1969] 2758/70 Heading F3A A percussion fuze for a rocket propelled hollow charge projectile comprises an electrical detonator 32, Fig. 1, mounted in a rotor 31, an electrical contact 40 for supplying current to the detonator from an impact sensitive piezoelectric device (not shown), a member 34 locking the rotor in a safe position, and an inertia safety mechanism formed by a ring 3, spheres 16 and 12, a cup 4, and a guide 5 for the electrical contact 40. A spring electrical contact (33, Fig. 3, not shown) carried by the rotor short circuits the detonator in the safe position. An electrical resistance is provided to dissipate the power arising from small impacts of the piezo-electric device. When the projectile is accelerated the ring 3 sets back and the spheres 16 move outwardly to permit the cup 4 to set back. Simultaneously the guide 5 moves slightly rearwards, and the spheres 12, no longer retained by the cup 4, move out of contact with the guide. On cessation of the acceleration, the guide 5 is moved forwardly by the spring 14 and displaces the locking member 34, whereupon a spring 36 rotates the rotor and brings the detonator into engagement with the contact 40.

Filed: 1970-11-07
Abstract: 1308817 A cage rack NUTRITIONAL RESEARCH UNIT Ltd 25 Jan 1972 [7 Nov 1970] 53064/70 Heading AIM A cabinet 1, open only at the front, has an air filter-fan system 11 mounted on its top, feeding clean air into a plenum chamber 4 at the rear of the cabinet from which the air emerges via slits in the back of the cabinet and passes over the tops of animal cages supported by shelves 6, so that each cage is ventilated and the venting air forms an air barrier to protect the cages from exposure to particulate matter in the surrounding environment or from adjacent cages. The cabinet is of moulded fibre glass strengthened by spaced wooden supports 2, fitted with a plurality of slidable shelves, to support the cages, which are reinforced at their front edge by a length of steel tubing 8 and are supported on slides 7 secured to the sides of the cabinet 1. The rear margin of each shelf is supported by a length of angled steel 9 so that no gap exists between the shelves and the vertical panel 3 and therefore preventing interference to the air flow. The fan housing 11 contains an intake fan 12, in front of which is an independent, removable air filter 14 so that clean air is forced downward into the plenum via the slot 5. To overcome turbulence, an air diffuser may be placed inside the plenum chamber so that an equal pressure distribution exists along the vertical back panel of the cabinet 3. Horizontal slits in this back allow the air to pass into the cabinet, over the top of the animal cages before venting at the front end so forming an effective air barrier which prevents the cages from being infected by matter from any other source. The cabinet can be mounted on castors to facilitate mobility of the unit.

Title: Electric motor speed control
IPC: H02P7/292
Filed: 1970-10-29
Abstract: 1319111 Control of DC motors CHILES (PATENTS & SYSTEMS) Ltd 29 Oct 1971 [29 Oct 1970] 51572/70 Heading H2J A reversible motor may be driven at a variable speed in either direction of rotation by the control circuit shown, in which a unidirectional current corresponding to one or other direction is produced between AC supply terminals PT1, PT2 and motor terminals M1, M2 by firing of an appropriate one of thyristors SCR1, SCR2 whose current path is completed by a corresponding diode D3, D2. At the centre wiper position of a potentiometer R3, neither thyristor is fired and the motor is stationary. Variable resistors R4, R5 are adjustable to determine the instant in each half-cycle at which the thyristors conduct and thus provide adjustment of the "flat spot" in the centre of the potentiometer and compensation for differences between the thyristors and motors to be controlled. Automatic speed regulation at any particular setting of the wiper of potentiometer R3 is inherently provided by virtue of the fact that a variation in load on the motor varies its back EMF, which varies the trigger potential applied through members R1, R2, D1, R3 in a compensating manner, such that the firing point of the conducting thyristor is varied to restore the speed to its previous set value. The motor A is a universal motor having a field winding F supplied through a full wave rectifier bridge D4-D7. Alternatively the field winding F may be across the terminals M1, M2 and the armature A may be supplied through the rectifier bridge, Fig. 2 (not shown). Application of the circuit to control a seriesfield motor is also described. Fig. 3 (not shown). Alternatively the motor may have a permanent magnet or separately-excited field.

Date Aug. 1, 1996The present invention relates to a method of working up and recovering returned explosives which are principally of the military type and which contain both fusible and non-fusible crystalline substances. In accordance with the invention, the returned explosive is treated in a multi-stage process which includes a first leaching stage for removing the non-crystalline, preferably fusible, component of the explosive in the form of trotyl, wax or plastic. The substance used in the leaching stage, principally toluene, does not affect the crystalline components of the explosive. The collected leaching liquid is separated off and the toluene, together with its dissolved content of trotyl or wax, is conveyed onwards for working up. The toluene which is recovered during the working up is returned to the process while the remaining filtrate from the filtration stage is treated with solvent which dissolves the crystalline high-energy explosives octagen and hexagen, respectively, which are relevant in this connection, which explosives, in a subsequent process stage, are precipitated out in the form of new crystals which, after a possible recrystallization, are ready to be reused. The solvent which is used in this connection is returned to the process.
