Abstract: 882,343. Mechanical garage and other storage systems. WHEELER, T. E. March 10, 1960, No. 8542/60. Class 78 (4). A multi-level storage structure has carriers arranged on each storage level in rank and file, any number of which carriers in a rank may be linked together to form a train which is movable towards and away from a shift space. Means are provided for moving one section of each carrier vertically between levels and control means for these movements are also provided. As described, a motor car may be stored in each of spaces 1-14, Fig. 6, in ranks A-G on each level except the ground floor of a multilevel car park. Each vehicle carrier comprises a lift fork section 20, Fig. 9, which is raised and lowered from a frame 21 by cables 22 wound on drums 23, power being supplied by belts 59 through a clutch 42. The carriers are coupled to form a train by solenoid-released gravity hooks 26, Fig. 4, the train being moved by wheels 27 and connecting rod 28 driven by a shaft 30. To park a vehicle in a given space A on a particular level an appropriate button is pressed. This breaks all the trains of carriers below the space A at an appropriate point and moves all these partial trains to clear a vertical shaft to the ground below the space A. As the carrier immediately below the space A is moved a bar 40, Fig. 10, is depressed by a roller 38 to extend guide blocks 41 and engage the clutch 42, Fig. 9. The clutch is disconnected and the guide blocks withdrawn as the bar 40 moves upwards. Engagement of the clutch closes a switch 48 which causes the lift fork to be lowered to the ground where a further switch is closed, which stops the lift forks. An attendant now starts up a conveyer which moves a vehicle on to the lift forks. As the vehicle moves on to the forks a tyre plate 63, Fig. 12, is pushed against a switch 64 which starts the lift forks moving upwards. A further switch is closed to arrest the lift forks when they reach the top of their travel. The carriages below the space A are finally moved to their original positions to leave the shift spaces at the ends of the ranks. A suitable electrical circuit is described for effecting the above automatic operation.

Abstract: 403,436. Filters. HENRY, R. A., 78, Quai de Rome, Liege, Belgium. March 22, 1933, No. 8636. Convention date, June 24, 1932. [Class 46.] In apparatus for filtering slimes wherein transverse filter buckets 8 in cavities 7 formed by radial partitions on a rotary drum 3 are subjected alternately to vacuum and compressed air, the buckets are in the form of deep pockets and receives the slimes under an external pressure greater than atmospheric. Two drums 3 may be mounted on pressure distributers 4 one on each side of an intake 2 having supply ports 6. The buckets 8 may be formed of cloth or melted fabric or of thick wire gauze whereon a fine gauze is soldered and the edges of the gauze may be embedded in frames 8a, Fig. 2, which are secured on the cavities by bolted cover frames 8b. The distributer 4 places the buckets travelling round an annular channel 4d in communication with a vacuum through holes 3a, and ports 4a, 4c in the channel. The caked slime is blown out when an aperture 3b in a cavity registers with an orifice 4f on the distributer and communicating with compressed air by a port 4b. The slime is introduced under a head of pressure provided by a tank arranged above the apparatus, such pressure being maintained by a leakproof casing 5. The tank may be fifty feet above the apparatus and the pressure may be increased by the velocity of the liquid introduced. The drums are relatively displaced by half the angle of their cavities and are thus filled alternately so as to limit the effect of the pressure on the filters. To prevent clogging the slime may be subjected to a preliminary treatment consisting in flocculation of the slime in suspension by alkaline earth hydroxides, particularly lime, or by a sol made with starch treated with alkaline hydroxides, or by both. Alternatively the slime may be mixed with amylaceous substances treated with caustic soda as by adding starch and alkali separately or together as a gel or as starch paste or as an unstable sol formed by partial reaction between the starch and alkali.
