Title: A method of and apparatus for decorating the surface of articles
IPC: B41K1/30
Filed: 1936-03-13
Abstract: 452,480. Printing processes and apparatus. OXVAR, Ltd., 3, Lower Regent Street, London.-(Oxford Varnish Corporation; Detroit, Michigan., U.S.A.) March 13, 1936, No. 7575. [Class 100 (ii)] A method for decorating the elongated surface of an article comprises applying a design to a pattern, transferring the design to a transfer roll by rolling such roll along the pattern and at the same time moving the roll relative to the pattern in the direction of its axis, and subsequently transferring the design for the transfer roll and the article to be decorated. The intaglio pattern roll 10, is carried by an axle supported in bushings in frame members 16, 19. The axle can be withdrawn endwise to change the roll after removing a set screw in the roll passing into a groove in the axle. The roll is driven through a pin-andslot connection by a pulley 30, driven through speed-reduction gear 27 from a motor 25. A pin-and-slot connection is also provided between the roll 10 and a cam 46 which is secured to a stub shaft on which is mounted a pulley 43. The pulley 43 drives a stub shaft 40 and thence, through a pin 39 engaging an abutment 38, the shaft 37 of an inking-roller 35. The roller 37 rotates in a bath 36 and is separated from the roll by a distance less than the thickness of the ink-film. The pattern-roller is scraped by a blade 55 carried on a shaft 56 and reciprocated, against spring pressure, by an arm pivoted to the frame and carrying a roller 161 engaging the cam 46. The resilient offset-roll 50 is placed in notches 70 in a carriage 60 slidably mounted in guides 75 on a slide-frame 62. The slide frame 62 is mounted for rotation on an annular ridge 64 of the machine frame and can be clamped at an acute angle to the plane of the roll 10 by a screw 66. In its initial position the carriage 60 is held against the right-hand end of the guide by a latch 80 and catch 81. The latch is released by the spindle 52 when the roll 50 is inserted and the carriage traverse is started by a spring plunger 83 and is continued by the frictional contact of the rolls 10, 50. The motion ceases when the roll 50 has been fed beyond the roll 10, and the roll 50, carrying a helical offset pattern, can then be removed from the carriage and rolled slantwise by hand along the article to be decorated. The carriage is returned by the engagement of a latch 90, released by the removal of the roll, with an abutment 93 on a constantly driven chain 94. The chain 94 is driven by helical gears 113, 116, an extensible rod 109 with a universal joint at either end, and a shaft 104 driven by sprocket-chain from the shaft of the pulley 43.

Filed: 1971-03-24
Abstract: 1378492 Carrying liquefied gases F H TURNER 2 Dec 1971 [4 Dec 1970 24 March 1971 21 June 1971 (3)] 57645/70 7680/71 28906/71 28907/71 and 28909/71 Heading B7A A floating storage tank or, as illustrated, a barge for carrying liquid methane has prestressed concrete walls made up of panels 15 each having outer and inner layers 15a and 15b separated by struts 15c. The barge is compartmented, Figs. 2 and 4 (not shown), by bulkheads made of similar panels. Corner joints are formed by concrete girders such as those shown at 16a and 16b. Rods 19 connect the panels and are tensioned after assembly. Tanks for methane may be located in the compartments or, as illustrated in Fig. 6 (not shown), the panels may themselves form the tank walls. In the latter case, the panels are covered with layers of thermal insulation which are themselves covered with a layer of aluminium or steel mesh and a layer of aluminium, steel or GRP sheet supported on a thin concrete backing. In order to avoid undue cooling of the concrete structure, thermal conductors, Fig. 4 (not shown), may be embedded in the vessel walls to conduct heat into the walls from the exterior of the vessel. Alternatively, electric or fluid circulation elements may be used to heat the walls. The methane in the tanks may, to avoid boil off, be cooled by heat exchangers, Fig. 2 (not shown), through which liquid nitrogen is circulated by a plant on the barge. If methane is allowed to boil off from the tanks, the vapour may be passed from the barge through a porous bronze plate located below the waterline, Fig. 7 (not shown), so that the methane is dispersed as an anti-pollution measure. When the barge is berthed, a tender carrying refrigerating plant may liquefy methane taken from the tank vapour spaces and then return it to the tanks. The tender may also be used to vaporize liquid methane from the tanks and to supply it to a point of use.

Title: Improvements in commutators having a marking multiple common to several marking devices
Inventor: GENERALE D ELECTRICITE COMPAGN
IPC: H04R25/00
Filed: 1946-03-14
Abstract: 646,196. Automatic exchange systems. COMPAGNIE GENERALE D'ELECTRICITE. March 14, 1946, No. 7984. Convention date, Sept. 7, 1943. [Class 40 (iv)] In a marker selection control system in which the markers employ separate current sources and simultaneous testing takes place over a common marking multiple, in the event of a cross-connection occurring, the two test relays involved operate in series with the two current sources in a symmetrical circuit. Operation of each test relay is followed by that of a vibrating relay in the associated marking device and these relays which operate non-synchronously destroy the symmetry of the test circuit and thus bring up a third relay of one of the markers which causes the associated selector to step on, and break down the cross-connection. As shown, when a cross-connection between the two selectors S1 and S2 occurs, the test relays 1 of the markers A and B operate in series with the current sources U in a circuit over the marking switches D and the common marking multiple; but since the circuit is symmetrical no potential difference exists across the relays 3. However, the test relays bring up the associated relays 2 which thereupon vibrate non-synchronously, each alternately removing and reconnecting the short-circuit across the resistor R1 in the corresponding marking device, so that when one resistor is in circuit and the other is short-circuited, the relay 3 of the first marking device operates to the potential difference produced across it and steps its associated selector, whereupon both the test relavs release and the selectors continue their searches. Specification 668,261 is referred to. Reference has been directed by the Comptroller to Specification 651,264.
