Patent GB-568822-A (GB)
Title: Printing
IPC: B41F3/34
Filed: 1943-09-02
Abstract: 568,822. Printing-machines; feeding webs. LOWE, J. M. Sept. 2, 1943, No. 14379. Convention date, March 25. [Classes 100 (i) and 100 (ii)] An offset lithographic multi-colour machine for printing repeat designs on fabrics is constructed with a reciprocating frame D, Fig. 2, which is moved by hand or mechanically over a bed fitted with printing-plates C1, C2, C3 which transfer impressions respectively to offset rollers E1, E2, E3 mounted in the frame D, the rollers acting to print a multi-colour impression on a length of fabric 65 arranged between rollers 66, 67. After one registered design has been printed the fabric is advanced to an extent equal to the length of the design, and the frame D is then returned to its starting position the rollers being raised out of contact with the printing-plates by means of a rail 20 which is raised to engage bearing surfaces on the ends of the rollers as the frame D returns to starting position. Other rails 50, 51 are set so as to act selectively on the rollers E1, E2, to trip these rollers as they pass the printing-plates C2, C3 with which they are not required to coact. The rollers E1., E2 are formed with grooves of different widths to effect this selective tripping. The rollers E1, E2, E3 are rotated by gears 91, 92, 93 at each end engaging fixed racks 17, so as to preserve registry of the designs. The web is advanced to the required extent by intermittent feed mechanism capable of adjustment, two forms being described. In Fig. 3 the web passes around feed rollers 110, 112 geared together, the roller 110 being driven by worm gearing from a roller 137 over which passes a serrated belt 136 which engages also pulleys 138, 139 of which the pulley 138 is adjustable so as to vary the distance between the numbers 137, 138. A peg on the frame D engages the belt 136 and as the peg moves from the wheel 137 to the pulley 138 a corresponding movement is imparted to the wheel 110, and to the web. In Fig. 5 the feed is controlled electrically and the extent of feed determined by the setting of an adjustable block 184 which controls the extent of movement of a wire 180 and a ratchet gear 160 on the shaft of the drum 110. A pin 200 on the frame D actuates a switch arm 210 which energizes a motor 199 which drives a pulley 192 counterclockwise and winds up a weight 194 and permits the wire 188 to move and also permits a wire 170 to move under the action of a weight 172 lighter than the weight 194. The ratchet gear 160 thus moves counterclockwise until a block 181 engages a fixed stop 183. The motor 199 is automatically de-energized by a switch 189, and then the weight 194 starts to fall and the wires 188, 180 move until the block 181 engages the adjustable block 184. The consequent clockwise movement of the ratchet 160 causes a predetermined movement of the drums 110 and 112. On the return of the frame D the pin 200 operates a switch arm 204 which re-sets the electric control device.

Title: Improvements in refrigerating system
IPC: F25D17/00
Filed: 1940-09-20
Abstract: 549,602. Automatic control systems. UNITED FRUIT CO. Sept. 20, 1940, No. 14407. Convention date, Sept. 22, 1939. [Class 38 (iv)] [Also in Group XIII] The rate of circulation and the temperature of cooled air circulating through cold-storage chambers for bananas and other fruits &c. on board ship or elsewhere are varied in accordance with the temperature of the air leaving the storage space in such a manner as to maintain a rapid circuiation until a fresh cargo is cooled down to storage temperature and thereafter a reduced circulation, with automatic regulation of the flow of brine or other medium for cooling the air and of the refrigerating plant for cooling the brine. The several chambers W, X, Y, Z, arranged between decks are each equipped with two fans 20, 21 for circulating the air over brine coils 26, 28 through ducts 30, 32 along the sides of the chambers beneath floor slots 14 and back through discharge openings 18, as described in Specifications 393,345 and 424,133, [both in Group X]. The brine coils are connected through flow and return mains 80, 46 with vessels 90, 92 cooled by evaporators of a refrigerating machine having two compressors 100, 102 and condensers 108, 110 which may be cooled by sea water circulated by pumps 50. The fan motors are controlled by a thermostat 150 in the path of discharged air, valves 140, 142 in the brine return main 46 are controlled by thermostats 144, 146 in the delivery air ducts, and the compressor motors are controlled by a thermostat 160 in the brine supply main 80. In starting up of the plant the sea water pumps are put in action and the flow of sea water actuates a switch at 317 to close the compressor motor circuits. The brine supply thermostat 160 may be of the kind comprising a mercury column 500, Fig. 4 with high temperature contacts h, f, g and low temperature contacts a ... e connected with a fourpole switch manually set to the full line position shown and held there by a solenoid 519, automatic release being effected when the temperature falls below the lowest contact e. The brine valves are actuated by reversible motors controlled by the thermostats 144, 146, and the speed of the fans is regulated by adjustment of resistances in the fan motor circuits by the thermostat 500. After the plant has been started up and as the brine temperature falls, firstly the speed of one compressor is reduced, and then one sea water pump motor is stopped and the compressor thereby stopped. If the brine cools still further the other compressor is similarly controlled. The Specification as open to inspection under Sect. 91 comprises also a direct-expansion air cooling plant, the expansion valves and compressor motors being controlled in accordance with the air temperature. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the manufacture of helically corrugated metal tubing
Inventor: LOVE JOHN
IPC: B21D15/04
Filed: 1954-05-17
Abstract: 761,475. Making corrugated tubes. K. A. C., Ltd. March 23, 1955 [May 17, 1954], No. 14424/54. Classes 83 (2) and 83 (4). A method of producing helically-corrugated metal tubing comprises engaging the coils of a helical spring with one annular surface of the tube wall, applying fluid pressure to the other annular surface of the tube wall until the yield point of the metal is reached, and then applying endwise pressure to said tubing and spring so as progressively to reduce the length of the tubing as the wall thereof is forced between the coils of said spring and to simultaneously reduce the pitch of the spring. A thin seamless metal tube 1 is mounted within a cylindrical casing 2. One end of the casing is closed by a cap 3 and the other end carries a conical flange 7 providing a housing for a sealing ring 8 retained in position by a collar 9 secured to the flange by a clamping ring 11. The collar carries an extension 12 the inner surface being of conical form for receiving the conical portion of a plug 14 which clamps the end of the tube against the collar extension. A split-collar 18 surrounds the tube and abuts against the collar 9. A brass helical spring 19 having a cross-section as shown in Fig. 4 is a close fit within the casing 2 and around the tube. The other end of the tube is closed by a piston 20 carrying a conical plug 23 coacting with a retaining ring 24 which screws into the piston. In operation, fluid pressure is supplied to the interior of the tube through a bore 15 in the plug 14 until the tube wall expands outwardly as shown in Fig. 2. Simultaneously, fluid pressure is supplied to piston 20 to counterbalance the pressure on the plug 23. Thereafter the pressure in the chamber 21 is gradually increased to cause the piston to move and collapse the tubing and decrease the pitch of the spring until the sides 29 of the rectangular portion of the spring abut (Fig. 3). The ends of the collars 18, 18<SP>1</SP> adjacent the spring 19 are provided with grooves 30 (Fig. 2), which taper off the corrugations in the tubing. The corrugated tube is removed from the casing by releasing the clamping ring 11 and withdrawing the tube and spring assembly from the casing. Whereafter the plug 14 and piston 20 are removed and the spring screwed off the tubing. To facilitate removal of the spring the outer surface of the tube may be waxed before corrugating. Multi-start corrugations may be formed on the tube by utilizing, e.g. three springs 19, 19<SP>1</SP>, 19<SP>11</SP>, equally spaced around the tube (Fig. 6). The pitch of the spring may vary along its length so that the depthof the convolutions of the corrugated tube will also vary. The difference between the width of the projection 25 and the rectangular portion 29 of the spring cross-section (Fig. 4), may be reduced so that the side walls of the corrugations abut to provide a helical fin on the tube. Specification 732,442, [Group XXV], is referred to.
