Title: Material feeding apparatus
IPC: B30B9/30
Filed: 1977-07-29
Abstract: The apparatus has a guide housing (7) with a charging aperture situated at the top, in which housing is provided a substantially horizontally operating conveyor slide (8) with cover plate (12). In the advanced operating position of the conveyor slide (8), the cover plate (12) closes the charging aperture and is thus exposed to the material to be additionally charged, which because of its composition - concrete blocks, rocks, metal objects - can result in damage to the cover plate (12) and operating faults. In order to absorb the stresses produced by falling material or material to be additionally charged without destruction or permanent distortion, despite a simple and cost-effective structure, it is proposed that the cover plate (12) be designed to be resiliently movable in the vertical direction, preferably as a support which bears freely at its ends. <IMAGE>

Patent GB-1561988-A (GB)
Title: Process and apparatus for dyeing hydrophobic fibres
IPC: D06B5/12
Filed: 1976-08-02
Abstract: Textile materials consisting of hydrophobic fibres are dyed in a closed dyeing system with water-insoluble disperse dyes by the exhaust method. In the process, the dye is introduced into the already circulating aqueous dye-free liquor which has been heated to the dyeing temperature together with the textile material to be dyed. This is done by mixing, in a bypass of the liquor main circulation, the dye which has not been predispersed and is present as a powder or paste with a relatively small portion of the hot, dye-free liquor, to which turbulent flow has been imparted, under overpressure, returning it in this state via a nozzle system to the liquor main circulation and there dispersing it at the same time. The process has the advantage that the dyes used need only be slurried prior to introduction into the liquor main circulation, but no longer have to be predispersed or processed in any other way. Reproducibility of dyeings obtained when employing this process is better than that which can be achieved when employing so-called depot techniques.

Abstract: 881,747. Pneumatic dispatch apparatus; step-by-step conveyers. AMF-SASIB S.p.A. SCIPIONE INNOCENTI-BOLOGNA. Sept. 21, 1959, No. 32114/59. Class 78 (1). Pneumatic apparatus for conveying cigarette packages P comprises an open-ended pneumatic tube 3 having substantially the-same section as the packages and having an ascending branch 403 leading from the dispatch station A and a descending branch 303 leading to the delivery station B, a port 4 in the branch 303 connected to air exhausting means, package discharging means 6 adapted to form temporary supporting means for the packages collected in the branch 303 in the form of a column below the port 4, means for stopping the delivery of the packages when the column does not reach a predetermined minimum level in the branch and means for stopping the feed of the packages into the branch 403 when the height of the column has reached a predetermined maximum normal height. The branch 303 may have a constant internal section or may have a part 503 at its delivery end of reduced cross-section. Packages are driven through the restricted passage 503 by a pair of friction rollers 40 which are driven in timed relationship with the rate of feeding packages to the branch 403. When light from a lamp 48 falls on a photo-electric cell 49 relay-controlled circuits are energized which stop the rollers 40 and keep them stopped until the passage of the light is interrupted by a package. When the branch 303 is of constant cross-section, the packages are held back by a lever 45 which normally is held clear of the opening 203 by a spring 46 but is pulled to the intercepting position by an electromagnet 47 which is energized at the same time as the cell 49. A second photo-electric cell may be disposed above the cell 49 and controls electric means which interrupt the operation of the pneumatic installation for a suitable time whenever the cell is de-energized for a predetermined time by packages extending above the cell.

Title: Improvements relating to Welding Apparatus for Making Welds Along Closed Circular Paths

IPC: B23K9/028
Filed: 1967-07-13
Abstract: 1,179,778. Welding by fusion. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 11 July, 1968 [13 July, 1967], No. 32337/67. Heading B3R. Apparatus for welding along closed circular paths comprises a rotatable work-table and a cam member co-operable with electrical circuitry for causing the end of the weld bead to overlap by a predetermined amount the bead previously deposited. Single-turn or concentric multi-turn welds may be made. In making a single-turn weld (Fig. 1, not shown), in which the end of the bead overlaps the start by an amount (T 1 ), the operation proceeds as follows: a pneumatic piston-and-cylinder arrangement moves an actuator 7 on to a rotatable worktable 1 carrying flux-coated work and the actuator 7, which may have a magnetic base, rotates with the table as the weld is formed. After one complete revolution the actuator 7 opens contacts of a switch LS3 carried by the head 5 of the piston 4 and the actuator is withdrawn from the table 1 as the piston 4 retracts thereby operating an overlap timer (T 1 ), (Fig. 5, not shown), which causes rotation of the table 1 to cease when the predetermined overlap (T 1 ) has been formed. In making a multiturn weld (Fig. 2, not shown), the weld bead is deposited continuously, the weld head being moved laterally at the completion of each revolution, except the last, of the table 1 and the end of the last concentric turn is overlapped with its start, the operation proceeding as follows: the actuator 7 is moved on to the table 1, and after one revolution it opens the contacts of switch LS3 but since the weld control circuit has been set to perform a continuous weld the actuator 7 remains on the table and the weld head is caused to move laterally by an amount determined by a timer (T 2 ) after which a further revolution of the table proceeds. This sequence is repeated automatically after each revolution of the table until the final turn of the weld is in progress, during which a switch is manually operated so that the apparatus completes the weld as if it were making a single-turn weld. The welding operation may be interrupted at any time and the table can be rotated in either direction to allow the weld to be inspected or repaired, after which the apparatus, when restarted with the table in the correct position, continues from where it left off.
