Title: Method of separating dust and solvents from explosive powder
IPC: C06B21/00
Filed: 1974-09-20
Abstract: 1483623 Upward current separation BOFORS AB 20 Sept 1974 [20 Sept 1973] 41180/74 Heading B2H [Also in Division Cl] In a method of separating excess graphite and powder dust and solvent residues from explosive powder, e.g. containing nitroglycerine, which has been surface-treated with means for controlling its burning velocity and/or graphite content, the powder is introduced into a container 3, Fig. 1, where it is caused to come into contact with an upwardly directed stream of water through which the powder falls down and is cleaned while at the same time the dust is transported upwards by the stream of water and is discharged via a spillway 8, the washed grains of powder that fall down passing into, or being transferred to, a vessel 4 in which the powder is treated with a plurality of changes of heated water which is passed through the vessel so as to extract the solvent residues from the powder which is then removed from the vessel and dried. The powder is contained in a vessel 1 from which it is injected by means of an ejector 2 and via a pipe 7 and an inlet 6 into the top of the container 3. Circular inserts 21, Fig. 2a, are provided within the container at its top to prevent exit of the injected powder directly through the spillway 8. The container 3 is connected to the vessel 4 by means of a tapered pipe 5 to which clean water is supplied via intake pipes 17 and 18 and a valve 19. Whirling elements are provided within the pipe 5 to cause whirling of the upwardly directed stream of clean water. The vessel 4 is supplied with water via a valve 10 and an intake 9. The water is circulated into and out of the vessel 4 via a heat-exchanger 12 by means of a pump 11. The water-treated powder is removed from the vessel via a drain valve 16 and dried.

[Class 138 (i).] In a washing-machine suitable for cleaning dishes, of the type having a horizontallydisposed outer casing containing a paddlewheel agitator which rotates round a carrier for the articles to be washed, the agitator and carrier are mounted on a pair of stub shafts, one fixed and one rotatable, the agitator being fixed on the rotatable shaft and rotatable about the fixed shaft, and the carrier being held stationary by non-rotatable engagement with the fixed shaft. As shown, an agitator 3 provided with blades 4 for splashing liquid upon articles in a carrier 2 is rotatably mounted within a casing 1. The casing has shafts 6, 7, the shaft 6, with which the agitator is rigid, being rotatably mounted and adapted to be rotated by hand or power. The shaft 7 is fixed in the end of the casing and has a bent portion 8 adapted to engage a groove 10 in the carrier 2 so that the latter is prevented from rotation. The carrier is of wire mesh with circular wire ends 9 by means of which it may be removed from the casing 1. The carrier may take the form of a wire mesh drum with a hinged, slidable, or detachable lid, or may comprise disc-like end walls which are preferably perforated and have longitudinally-extending members between them to form a cage. The blades 4 of the agitator 3 may be arranged helically instead of parallel with the axis. The radial yokes 14 may be constructed to act as blades. The interior of the casing may have baffles to deflect the water raised by the agitator. According to the Provisional Specification, the carrier, instead of being stationary, may be rotatable either in the same direction as that of the agitator, or in the opposite direction. In a modification, the agitator may be dispensed with, the blades being fixed to the carrier.

Abstract: 1505093 Vehicle transponder WESTINGHOUSE AIR BRAKE CO 28 Oct 1975 [15 Nov 1974] 44248/75 Heading H4L A transponder for an automatic identification system for vehicles and co-operating with interrogating signals from loops adjacent the vehicle path incorporates a receiving coil L1 tuned, by a capacitor C1, to the frequency f of the interrogating signal and a rectifier, incorporating diodes D1, D2, to provide the transponder operating potential. The interrogating signal is also applied to a multistage frequency divider FD via lead W7. This provides a f/2 frequency output from its first stage which is applied to inputs of a NOR gate logic circuit LN. A shift register SR has set into it coded data identifying the vehicle. A latching circuit LC operates when the voltage derived from the rectifier reaches a threshold (set by Zener diode Z I ) to initiate transfer of the shift register code to the latching circuit in accordance with f/m clock pulses derived from the final output of the divider FD. The shift register output phase modulates the f/2 signal applied to the logic circuit LN in accordance with the binary data in a push pull amplifier BA to which f/2 is directly applied via the lead W. The amplifier output incorporates a tuned transmitting coil L2C2 for returning the modulated signal to the interrogator.
