Title: A process and device for the seamless coating of printing cylinders
IPC: G03F7/18
Filed: 1959-08-18
Abstract: <PICT:0876827/III/1> A seamless coating of photosensitive solution is applied to a printing cylinder by introducing it into, and withdrawing it from, a bath of the solution, and blowing a forced draught of filtered air against the surface of the cylinder above the liquid surface during these operations.  As shown, a cylinder 11 to be coated, is mounted on a plunger-like tank bottom 3, and is lowered into the jacketted tank 1.  The space 14 between the cylinder and the tank wall is kept filled with the photosensitive solution which is supplied from a vertically-movable vessel 8 to an encircling channel 4, from whence it flows into the said space.  The connection between the channel 4 and the vessel 8 is then broken at 17, and the vessel lowered; the cylinder 11 is raised, and the overflowing solution returned to the vessel 8 through a filter 18.  A protective shield of filtered air is provided above the surface of the liquid in the tank 1 by supplying the air from a pump 20, or a supply tank, to a feed space 9 around the top of the tank whence it is directed through slits or jets 10, towards the cylinder 11.  The jets may be directed radially inward, or along a tangent or chord of the tank, and may be provided with closure means.  A transparent cover 19 is provided.

Title: Improvements in or relating to conveyor installations
Inventor: ORWIN OLAF JOHN BARCLAY
IPC: B61B10/02
Filed: 1954-10-02
Abstract: 819,343. Conveyers. FISHER & LUDLOW Ltd. Jan. 2, 1956 [Oct. 2, 1954; Dec. 9, 1955], Nos. 28423/54 and 35335/55. Class 104 (2). In a conveyer system in which load carrying trolleys are propelled along a track 12 by pusher dogs 22 supported by a driving chain 11 running on a track 10 and engaging and driving abutment bar 17 on each trolley, means are provided to arrest a trolley in one of a series of positions at locations along the track by pivoting the driving dog to inoperative position disengaging the bar 17 by the dog striking a cam 38 on a master disengaging element 31a normally maintained in operative position and mounted on sections of a spindle 34; the trolley strikes the forward, chamfered edge of an L-shaped actuating member 32a mounted on the sections of the spindle 34 rotating the member and a section of the spindle 34 carrying the reset disengaging member 31b pivoting this member to operative position where the cam 38 arrests the next trolley which strikes and pivots the actuating member 326, rotating the next section of the spindle and the disengaging member 31c mounted thereon to operative position to arrest the trolley. The operator retains the master disengaging element at the store in operative position to arrest the feeding of any further loaded trolleys on to the conveyer. If the operator omits to do this the trolleys actuate two microswitches simultaneously one being adjacent the disengaging element 31c and one to the rear thereof and the chain is arrested. At the conclusion of the assembly operation a latch 53 retaining the master disengaging element 31a is released, allowing a driving dog to pivot and propel the trolley away. The disengaging element is relatched in operative position. The actuating member 32a pivots to operative position.as the trolley moves from the disengaging element, causing the next disengaging element 31b to pivot to inoperative position allowing the next trolley to be driven to the master disengaging element 31a which arrests it. The actuating element 32b pivots causing the disengaging element 31c to move to inoperative position allowing the next trolley to be driven to the next disengaging element 31b which arrests it. The trolley pivots the actuating member 32b, rotating the disengaging element 31c to operative position and arrests the next trolley. In this way the trolleys are forwarded one by one to the assembly position. To prevent forward movement of the trolley at the arrested position each disengaging element has a stud 47 which engages the bar 17. To prevent swing- ing the trolley plates have a pawl bar 51 which passes under and engages a pivoted ratchet 48 in the arrested position of the trolley. Specifications 639,244, 737,265 and 759,371 are referred to.

Title: Improvements in and relating to the production of polythioureas
Inventor: WATERS DAVID JOHN
IPC: C08L75/02
Filed: 1950-11-21
Abstract: Polythioureas are made by reacting carbon disulphide with a diamine in which the amino groups are separated by a chain containing at least three carbon atoms to form an intermediate salt, heating this salt in presence of water or steam until an intermediate polymer is precipitated, removing a substantial part of the aqueous liquor associated with the intermediate polymer, and heating the intermediate polymer in presence of water or steam until a thermoplastic fibre-forming polythiourea is obtained. Heating is preferably effected in an autocalve having a current of steam passing through it.  In examples the salt is prepared in presence of triethanolamine and oleic acid.  Specifications 524,795, 534,699 and 660,905 are referred to.

Abstract: 1,015,204. Feeding webs. H. E. TELGHEIDER. July 18, 1963 [July 19, 1962], No. 28526/63. Heading B6B. [Also in Division F2] A spreader roller used for transverse stretching of webs of paper, textiles &c. comprises a fixed support rod about which is journalled a cylinder having rubber, metal &c. bars lying axially along its surface and secured at their ends to clamp blocks journalled for rotation about axes inclined to the rod, so that during each rotation of the cylinder the bars are first stretched and then allowed to contract, a spirally-wound cord or the like threaded through the bars holding them against the surface of the cylinder. In one form, a steel cylinder 42, Fig. 5, is journalled about a rod 20 upon which are mounted at oppositely-disposed angles blocks 22, Fig. 3, journalling rings 62 clamped to the ends of rubber bars 12, Fig. 6, lying around the cylinder, a spirally-wound cord 80 threaded through the bars holding the latter against the cylinder. Thus as the roller rotates, the rubber bars 12 are alternately stretched and relaxed, so that a web running over the bars is correspondingly stretched. In a modification, the block 22, Fig. 7, is pivoted about an axis perpendicular to the rod 20 by a pin 104 at an angle which may be adjusted by turning screws 108, thus permitting control of the extent to which the rubber bars 12 are stretched. In this form, the rubber bars 12, Fig. 8, are reinforced by embedded metal springs 110 anchored at their outer ends to pins 116. The web fed over the roller may be kept in contact with the rubber bars by an idle belt 120, Figs. 9, 10, running over pulleys 122 and engaging the edge of the web. The rubber bars 12 may be replaced by metal springs 200, Fig. 11, in axial slots 212 in the roller, a spirally-wound cord 80 holding the springs in place; as a modification of this form, Fig. 15 (not shown), three metal springs 200 are arranged side-by-side in each slot. In another similar modification, Figs. 16, 17 (also not shown), the roller is deeply slotted to receive the metal springs and a surrounding spirally-wound cord lies in notches in the outer edge of each spring.
