Title: 11-piperazinyldibenzo b f 1 4 oxazepins and thiazepins
Inventor: JOSEPH MCEVOY FRANCIS
IPC: A61K31/495
Filed: 1968-10-11
Abstract: Compounds of formula (I) R1 = H, alkyl, hydroxyalkyl; X = O or S. Also their acid addition salts. Tranquillisers and antidepressants. A mixture of 4-methyl-2'-(p-trifluoromethoxyphenyl)-1-piperazinecarboxanilide (2.5g), P2O5 (2.5g) and POCl3 (25 ml) was refluxed for 24 hr., the solution was evap. and the residue was treated with water. 6N HCl was added, the mixture was filtered and the filtrate was neutralised with NaOH and then basified with NaHCO3. The solution was extracted with ether and the dried extract was evap. The residue was dissolved in CH2Cl2 and chromatographed on a magnesia/silica gel column, eluting first with CH2Cl2 and then with a mixture of acetone/CH2Cl2. The solvent was evap. from the eluate to give 11-(4-methylpiperazino)-2-trifluoromethoxy-dibenzo (b,f) (1,4)-oxazepin which was converted to the hydrochloride with ethereal HCl. This compound provoked ataxia at 4mg/kg and depressed motor activity at 1.4mg/kg.

Title: Gravel or coal quarrying or open casting - spiked cylinder lowered and raised over stope, locked in one direction
Inventor: TRAUB FRANZ
IPC: E21C47/00
Filed: 1973-09-20
Abstract: Quarrying gravel or mining coal in an open pit or quarry with sloping stopes is effected by means of a body which can be moved under power so as to dig or scoop in one direction and simply roll over the stope in the other direction of movement. The body should preferably be guided vertically up and down the stope wall, or moved through an arcuate trajectory over the stope, driven from either above or the base of the stope as convenient. The body should be a cylinder fitted with teeth, spikes etc. on the outside, carried with free movement on the drive in one direction but locked in the reverse sense. This locking should be such as to ensure that a row of spikes or teeth directly confronts the face of the stope in work.

Title: Lighting unit with tubular stand - has sliding piston in slotted stand for holding lighting unit housing
Inventor: KONIETZNY KARL
IPC: F21V21/34
Filed: 1973-10-31
Abstract: The lighting unit whose position is adjusted by the slotted tube and piston arrangement is supplied with current through a cable which is concealed within the slotted tube. One such tube can also accommodate a number of arms for supporting a number of lighting units. The height of the lighting unit is adjusted by sliding the piston within the slotted tube. The piston is self-locking due to friction as well as due to the tilting effect exerted by the weight of the lighting unit. The tube used can be of circular or polygonal cross section. A number of these support tubes can be assembled in parallel for supporting a number of lighting units or the tubes can be held on support elements of different configuration to produce lighting fittings of different shapes. The slotted tube accommodates the piston to which is connected the end of the power cable. The lighting fitting is supported by a projecting arm with a spherical end so that the support tube for the lighting unit can be tilted at any required angle. The power cable passes to the lighting unit through the hollow bores of the connecting elements.

Title: Effluent treatment plant for removing ferromagnetic impurities - with coarser matter pptd directly into sump, and remainder sped magnetically
Inventor: KOEGL WOLFGANG
IPC: B01D21/00
Filed: 1974-03-20
Abstract: Effluents contg. ferromagnetic impurities, are purified by turning the flow of water upwards so that rapidly sinking impurities fall into a sump for draining off and disposal whilst unpptd. matter is carried over. In the addn. the feed of the effluent contg. ferromagnetic impurities is first directed downwards into a funnerl and then deflected upwards so as to separate out the coarser pollutants which settle into a sump. whilst the flow, slowing down as it passes through the widening zone of the funnel, trickles over magnetic plates to which the magnetic impurities adhere, a rotay scraper pushing them at intervals into the sump. Process removes practically the whole of the ferromagnetic impurities from the effluent.
