Abstract: 1476228 Mixing apparatus CIBA-GEIGY AG 19 Dec 1975 [19 Dec 1974] 54867/74 Heading B1C A photographic emulsion making vessel 1 which is conical in shape but optionally is truncated by a bottom outlet valve 2 and which is arranged with the apex of the cone facing downwards, comprises a stirrer shaft 3 eccentrically mounted in the vessel at approximately half the radius of the vessel and inclined towards the apex, the shaft bearing a plurality of pitched impellers 4, 5 etc the diameter of each being from 0.35 to 0.6 of the diameter of the vessel at the level at which the said impeller is mounted on the shaft, the lowest impeller 4 being mounted in the lower half of the height of the vessel and the height of each subsequent impeller being from 1.2 to 1.6 times the height of the impeller above which it is mounted from the apex of the cone or from the imaginary apex of the cone if truncated. The impellers are preferably 4-bladed turbine type impellors with the blades pitched at 30. The vessel includes one or more baffles 9 mounted close to but not touching the walls and intended for inducing axial rather than rotary circulation. In use for the preparation of a monodispersed silver halide emulsion the volume of materials to be mixed is initially small e.g. at a level 8 which is 32 cms from the apex of an 80 cm high vessel, and mixing proceeds with metered amounts of materials being added to increase the level.

Title: Camera having automatic exposure control

Abstract: 1385577 Automatic exposure control AGFA-GEVAERT AG 29 Nov 1972 [29 Nov 1971] 55158/72 Heading G2A A camera includes means for controlling automatically both diaphragm aperture and exposure time comprising a diaphragm operating member 1 which has mechanical retarding means 6, 9 and which, during run down drives the diaphragm so that the aperture varies continuously in a single direction from an initial to a final value, and electronic timing means 17 including a photosensitive element and controlling a shutter release electromagnet 18, 19, the timing means being brought into operation when the diaphragm operating member 1 is released to change the operative state of the electromagnet to release the shutter after a time determined by the prevailing illumination, the time for which the shutter is open being determined by the instantaneous value of the diaphragm aperture when the shutter is released. In operation initial depression of a pawl 9 closes contacts 30 and 32 connecting a voltage  source 31 to the timing means 17 and to an indicator circuit 33 including a lamp 58 which indicates whether the lighting conditions are adequate for exposure. Further actuation of pawl 9 releases the diaphragm operating member 1 which runs down continuously under the influence of a spring 8 and retarding mechanism 6, 7. As member 1 runs down an exposure time control cam 10 provided on member 1 pivots a control lever 11 connected to a retarding means 14 and in addition a contact 16 opens and a contact 35 closes so that a capacitor 53 in the timing means circuit charges at a rate determined by the prevailing illumination incident on a photo-cell 51. The output of the capacitor is connected to a trigger stage 50 and when the threshold value of the latter is reached the electromagnet 18, 19 is de-energized releasing an armature 20 and allowing a shutter opening member 25 to rotate unretarded under the influence of a spring 26. A shutter closing member 27, which is retained in position by a projection 29 co-operating with a projection 28 on the shutter opening member also commences to rotate almost simultaneously under the influence of a spring, (not shown) but is retarded by the retarding mechanism 14 when projection 29 engages with the control lever 11. The amount by which member 27 is retarded, and hence the time for which the shutter is open is determined by the position of the lever 11, which in turn is determined by the position of the control cam 10 at the time at which the shutter is released in alternative timing circuits the trigger device is connected to a tapping between a photo-resistor and a fixed resistor, which together form a potential divider, or the output from a potential divider, comprising a fixed resistor and a photo-transistor, is connected to a transistor whose output is connected to electromagnet 18, 19. The light beam falling on the photo-cell or photo-transistor may be attenuated by means e.g. a neutral density wedge, coupled to the diaphragm operating member.

An acoustic directional transmitting and/or receiving system comprising an arrangement of transducers or groups of transducers of different extent perpendicular to the major lobe of their corresponding directional characteristic, the n-directional characteristics being in different directions, is characterized in that the n-transmitting and/or receiving channels which are connected to the arrangement for different frequencies or frequency bands are such that the different frequencies or, for the case of frequency bands, the centre frequencies, are inversely proportional to the extents; and in the case of frequency bands the ratio of bandwidth to centre frequency is constant. In a configuration of receiving transducers S 1 , S 2  ... Sn grouped into sets d 1 , d 2  ... dn, the corresponding directions P 1 , P 2  ... P n  have equal beam widths if band-pass filters F 1 , F 2  ... F n  are employed, the centre frequencies of which are inversely proportional to the extents d 1 , d 2  ... d n , the ratio of bandwidth to centre frequency being kept constant. Compensators N 1 , N 2  ... N n  may be incorporated. For indicating direction the channels 1, 2 ... n may be scanned as described in Specification 1,220,629. For aural direction-finding the outputs of scanner A are heterodyned to a common frequency band. Each bearing P may be found utilizing the sum-and-difference method; or each set d may be subdivided into two groups, each having a band-pass filter, the two filters feeding a correlator, Fig. 2 (not shown). In a further embodiment the sets d may be fed sequentially to a band-pass filter of variable bandwidth, Fig. 3 (not shown).

The strands 12 are cut by a device 7 actuated from a device 8, e.g. a light barrier, or digital measuring system, or comprising a limit switch operated upon displacement of a control arm thereof by the strand leading end. The moulding material may comprise various specified thermoplastic and thermosetting materials, including rigid and plasticised P.V.C. and polyurethane, foamable polymers and waxes, and which may be applied to various substrates which are removed with the coating of material from the higher speed roll, around a pressure roller. In the examples, plasticized P.V.C. material is coated on to a cotton material and a polyurethane sheet is moulded. Several strands may be simultaneously delivered into the nip and the strand or strands may comprise different materials or colours, e.g. blue and green. A gap 13 is produced between sequential strands 12, by the belt 6 running at a speed which is faster than that of extrusion, and is also variable from a drive 14. The cut strand 12 is delivered along an inclined grid 19 into the nip 20, upon ejection from the belt 6 by a metal plate 17, pivoted with a bar 9 by a pneumatic drive 18 actuated by a digital measuring system, or from a limit switch 15 upon deflection of an arm 16 thereof by the leading cut end of the strand 12. The switches 8 and 15 are slidably adjustable along the bar 9. In the Fig. 2 embodiment (not shown), the extrusion (4) is delivered from the extruder to the belt (6), via an upwardly inclined conveyer belt (24) and through a variable speed roller guide nip (26) at the downstream end thereof, at which it is cut by the device 7. The upwardly inclined belt (24) may define a conveying surface which is planar, or trough shaped as determined by guide rollers.
