IPC: B07B1/52
Abstract: 1,054,503. Cleaning screens. MEHLENBAU DRESDEN VEB. Jan. 14, 1965. No. 1661/65. Heading B2H. In a screen separator, a screen 1, which is adjustable in its angle of inclination and is subjected to a vertical vibratory movement taking a circular or elliptical course, is cleaned by means of a multi-blade brush 2 having a centrally situated bearing 5 permitting step by step relation as well as vertical vibration of the brush. Each blade of the brush 2 is linked to a corner brush 3. The bearing 5 consists of a housing 6 in which is secured a pin 7 which engages in a sleeve 8 mounted in a support 11 underneath the screen fabric 10. A spring 9 urges the brush 2 against the screen fabric. A number of brushes are mounted on a corresponding number of supports 11 spaced equally underneath the screen fabric. In operation as the screen moves downwards, some of the bristles 13 are pressed downwards and some are thrust through the screen fabric which is thereby cleaned. As the screen moves upwards again, the bristles which have been pressed down are released and tend to return to their initial position causing the brush to move on.

An endless length of textile material is treated with a liquid in a treatment chamber 22 having a J-shaped guiding channel 27 for the material extending from a guiding reel 25 near the top of the chamber to a perforated intermediate floor 23 beneath which is a heatregulating chamber. The guide channel 27, through which the material may pass in either direction, may be situated. outside the treatment chamber (Fig. 5, not shown) or inside the treatment chamber, as shown, when it is protected by a perforated wall 26 whose perforations may be partially shielded by a slider 26a. Liquid is supplied by a pump to an annular nozzle in a feeding funnel 27c and to the lower portion of the guiding channel 27 in the direction of movement of the material and to the lower part of the chamber and guiding channel via the heat regulating chamber in a direction opposing the movement of the material. Liquid is recirculated to the pump from a discharge duct behind the perforated wall 26 and a pipe in the heat regulating chamber. In modifications, liquid return ducts may be situated in the wall of the treatment chamber or at the base of an annular space between the chamber wall and a concentric cylinder perforated at its upper end. When the material passes downwardly through the chamber a rotating output tube 27d is provided on the funnel 27c and when the material passes upwardly a movable ring connected to a stopping mechanism for the guiding device may be provided.

Abstract: 1,258,144. X-ray examination tables. WESTINGHOUSE ELECTRIC CORP. 5 Nov., 1969 [22 Nov., 1968], No. 54262/69. Heading H5R. An X-ray table comprises an elongated table body 2 having a horizontal normal position and being tiltable about a transverse axis 4 by means of a tilt drive, a table top 5 supported on the table body 2 for floating movement relative thereto and longitudinal thereof, reversible power drive 13, Fig. 4, for driving the table top 5 and a manually operable arrangement 7 movable to a coupling and an uncoupling position for respectively coupling and uncoupling the table top 5 to and from the power drive 13 thus enabling the table top to be positively driven by the power drive or to be floated manually. As shown, the table top is mounted on crosscarriage frame 6 which is supported for floating transverse movement thereof on the table body 2 and which houses one or more chain drives 8, 9, connected to a reversible motor 13, for selectively co-operating with the table top 5. When connecting the table top 5 to the chain drives the lever 7 is operated to move, for example by the linkage arrangement shown in Fig. 12, a dog 20 into engagement with a socket 19 mounted on the chains 9. Alternatively, Fig. 16 (not shown), a series of dogs co-operating directly with the chain links may be used. A pin may be provided on the lever 7, Fig. 13 (not shown), which allows operation thereof only when the table top is in its central position on the frame 6 and the pin aligns with a slot in the frame. When lever 7 is moved to the manual float position-i.e. to the right in Fig. 12-the linkage via a pin 67 operates a switch, Fig. 11 (not shown), which prevents the chain drive and the tilt drive from being energized. In addition a mercury switch is energized upon tilting of the table-only possible when lever 7 is in the power drive position-to move a plunger into a locking hole 76 in the linkage of Fig. 12 to prevent operation of the lever 7 whilst the table is tilted. Electromagnetic locking mechanisms may receive the table in any desired position, and, when in the chain drive mode, may be disengaged automatically when the drive motor is started.

However if the jacks and thus air brakes fail to move uniformly the feedback to the levers 14, 15 will cause them to move unequally whereby the cam 16 rocks the follower 17 to displace the spool valve to increase the supply to one jack whilst reducing the supply to the other jack so that uniform movement of both jacks is re-established and the components of the lever system 10 are realigned. In the arrangement as shown an unequal angular movement, between the levers 14, 15, of 6 degrees in each direction of lever rotation provides the total linear movement required to move the spool valve 12 over its full travel. When the unequal angular movement further increases, i.e. beyond the 6 degrees, the cam follower 17 rides over the cam 16 to freely slide thereon without further rotation whereby the spool valve link 11 remains substantially stationary, thereby preventing damage to the spool valve assembly 13.

The incoming effluent may be preheated in a second heat exchanger 3. The fume incinerator of Fig. 1 forms part of paint drying plant, Fig. 3, having an oven 40 to which heated air from the incinerator 42 passes to two heaters 30, 30a through fans 41, 41a and is delivered to different zones of the oven 40. The effluent from the oven 40 is burnt in the incinerator 42. Change over dumpers 31, 32 enable part of the burnt effluent from incinerator 42 to be recirculated through the oven. In another arrangement, (Fig. 5) the air passing to the oven is heated by mixing it with the burnt effluent, and the temperature of the air delivered to each zone is controlled by further admixture of fresh air. In the plant of Fig. 6, air passing to a process chamber 50 is heated directly by mixing with the burnt effluent from fume incinerator 52, and heated gas not used in the chamber 50 is passed to heaters 82 for solution tanks 83. The remaining hot air is mixed with air from the heaters 82 to operate air heating equipment 88, 89, which may be used for space heating. Supplementary heaters 90, 91, 92 enables additional hot air to be supplied to the tank heaters 82 and space heaters 88, 89.
