Title: Method of and device for Stacking Plate Shaped Moulded Bodies
IPC: B65G57/06
Filed: 1967-12-22
Abstract: 1,151,976. Stacking articles. SCHLOSSER & CO. G.m.b.H. 22 Dec., 1967 [7 Sept., 1967], No. 58517/67. Heading B8C. In stacking moulded slab-like bodies 4 they are fed on a conveyer 1 and may be first stacked in a small group by expandable grab arms 8 on the conveyer and then fed to collector 10 at which a pair of tongs 12 receives them and loads them on to one or other of depositing forks 15, 18 (Fig. 2, not shown). The latter operate in turn to receive slabs and is lowered as each group of slabs is deposited thereon. When a set of say 20 slabs has been deposited on one fork this is further lowered so as to deposit the set of slabs in a swinging device 25 and the fork is slid from beneath the set whilst at the same time the other fork is slid into position above the set to receive subsequent slabs thereon. The device 25 is then operated and swings downwards through 90 degrees to deposit the slabs on a pallet 31 on an endless conveyer which is moved an appropriate distance after each set of slabs has been deposited. The slabs are thus stacked vertically on the pallets. When a pallet is full it is pushed sideways off the conveyer to a station 40 (Fig. 3, not shown), at which suitable tongs grip the entire stack of slabs and transfer it to another conveyance. The pallet is then returned to its starting position for re-feeding on to the conveyer.

The production of dinitrogen tetroxide by the combustion of air with ammonia in the presence of a catalyst, oxidation of the resulting gas mixture of NO and NO 2  at an elevated temperature with nitric acid and subsequent isolation of N 2 O 4  by compression of the gas mixture and cooling, is improved by carrying out the compression to a pressure of at least 4 atmospheres and cooling to not less than 8 C., after which part of the NO 2  is withdrawn as liquid N 2 O 4 , the oxygen content of the gas mixture is supplemented with air at least stoichiometrically sufficient for the formation of N 2 O 5  from NO 2  and the resulting mixture treated with nitric acid from the oxidation step until a nitric acid of concentration 55-70% by weight is obtained at least part of which is recycled to the oxidation stage. The residue NO in the gas mixture after compression but before cooling is removed by allowing it to continue to react in the presence of air added before the compression. When the process is carried out continuously the water which accumulates is removed as nitric acid during the oxidation of NO, the removed acid having a concentration between that of the concentrated nitric acid employed and the dilute nitric acid arising after the oxidation.

Title: Cooling method
IPC: B22C5/08
Filed: 1979-02-23
Abstract: In making resin-bonded moulds or cores for use in the foundry, it is important that the sand is not at a temperature at which the resin cures. With reference to Figure 1 of the drawings, sand recovered from resin-bonded moulds or cores, or obtained from quarries is cooled in a fluidised bed cooler having a cooling chamber 112. Air is supplied to the chamber 112 through a plenum chamber 110 via conduits 126. Sand is introduced into the chamber 112 from an inlet 116 and is fluidised by the air, thus being cooled, and the cooled sand leaves the chamber 112 through an outlet 120. Liquid nitrogen is sprayed into the air entering the conduits 126 so as to reduce the temperature of the air to below ambient, and thereby enable the sand to be reduced in temperature to below ambient. <IMAGE>

Patent GB-2070877-A (GB)
Title: Range finding apparatus
IPC: G01C3/10
Filed: 1980-03-04
Abstract: The invention relates to binocular range finding apparatus which scans a field of view from two different positions so as to produce two images of an object, which images are detected at different times, the separation between these times being indicative of range, and is characterised in that the field of view is viewed in divergent directions from the two apertures. In the illustrated apparatus radiation from a field of view is received at apertures 2 and 3 from respective diverging directions d1 and d2. An optical system focusses the radiation from apertures 2 and 3 onto a common image plane 15 so as to form two images which are displaced from each other and superimposed at the plane 15. A scanning system in the form of a mirrored polygonal drum 11 sweeps the superimposed images across the plane 15 so that the two images of a particular object in the field of view fall in turn on the detector 14. The spacial separation between the two images of the object is indicative of range and therefore the temporal spacing of the signals from the detector 14 are also an indication of range. Because the two directions d1 and d2 diverge there is no possibility of light from an object entering aperture 3 and being focussed onto the detector 14 at the same time as light from the object enters aperture 2 and is focussed onto detector 14. <IMAGE>
