IPC: B05D1/20
Filed: 1966-04-28
Abstract: 1,125,458. Ornamenting. IMPERIAL CHEMICAL INDUSTRIES Ltd. 16 March, 1967 [28 April, 1966], No. 18680/66. Heading B6G. [Also in Divisions B2 and G5] A decorative finish is applied to an article of a synthetic thermoplastic organic polymeric material by applying to the surface of a liquid medium a hardenable liquid composition that is immiscible with and which will float upon the liquid medium to form a thin layer of the hardenable liquid composition on the surface of the liquid medium and thereafter transferring the layer of the hardenable liquid composition on to the surface of the article. The hardenable liquid composition is an oil-based paint or a paint comprising a dispersion of a pigment in a solution of a polymeric binder, e.g. polymethyl methacrylate. The preferred liquid supporting medium is water. The layer of the hardenable liquid composition may be lifted from the supporting liquid medium by means of the article which may have been immersed in the liquid medium, or the article may be pressed in contact with the layer of hardenable liquid composition. Synthetic thermoplastic organic poly. meric materials mentioned are polymers and copolymers of esters of acrylic, methacrylic acids, polymers of vinyl chloride or copolymers of vinyl chloride with, say, vinyl acetate, alkyl acrylates, vinylidene chloride, and polystyrene. A protective layer may be applied to the coated surface by spraying or by laminating a further sheet thereto. The article may be in the form of a sheet shaped by, e.g., vacuum forming or blow moulding after a decorative layer has been applied, or the decorative effects may be applied after shaping. Portions of this surface of the article may be masked, and several applications of decorative layers may be made either of the same or different hardenable liquid compositions. Examples of decorative articles made are bowl lamp shades, panels, signs for advertisements.
Patent GB-557611-A (GB)
Title: Improvements relating to textile fabrics
IPC: D06M15/693
Filed: 1942-05-15
Abstract: 557,611. Treating textiles with liquids &c. BREW, H. E. May 15, 1942, No. 18681/43. Divided out of 557,420. [Class 15 (ii)] A textile yarn is treated at some parts only with an activating agent, i.e. a substance which promotes deposition of rubber or the like from dispersions thereof, and is then knitted or woven into a fabric ; the fabric is passed through a dispersion of rubber or rubber-like substance so that a deposition of rubber or the like takes place at the pre-treated parts of the yarn which thereby becomes united to itself only where two treated parts cross in contact. The activating agent may be a cation-active or an anion-active substance, in which case the dispersion will be one having particles of the opposite charge, or it may be a coagulating agent. The yarn may be pre-treated with the activating agent at intervals along its length, or if it is a composite yarn, one or more but not all of its components may be treated along its whole length. In an example, a viscose rayon thread is padded, before twisting, with an aqueous solution of cetyl-pyridiniumbromide. After knitting, the material is immersed in a dilute rubber latex. The negatively-charged latex particles are deposited on the positively-charged thread where it carries the cationic soap, but not on the untreated portions, nor on the other threads which last may have been treated with an agent to prevent wetting-out by the latex. The material is washed and dried and during drying the deposited rubber produces adhesion where the padded yarns cross in mutual contact. The amount of rubber deposited may be varied by adjusting the amount of cationic soap applied in the pre-treatment and by adjusting the concentration of the. latex. Instead of natural rubber latex, a vulcanized latex or a latex of a synthetic rubber may be used. The treated fabrics are rendered resistant to laddering or slipping of the yarns. Specification 538,865 is referred to.

Title: Improvements in and relating to safety locking devices in centrifugal machines, moreparticularly electrically driven centrifugal laundry drying machines
IPC: D06F49/00
Filed: 1956-06-18
Abstract: 837,600. Machinery guards. ZANKER, P. June 18, 1956 [June 18, 1955], No. 18776/56. Class 80 (4). [Also in Group XIII] Closing the lid 6, Fig. 1, of a spin-drier causes simultaneous automatic locking of the lid in the closed position and winding of a timer mechanism 11 which subsequently controls the drier's operation. When the lid is open and the mechanism 11 run down, the push-button 16 of the motor control switch 15 will be held in an " off " position by a resilient arm 24, Figs. 2, 3, under the action of a cam disc 17 and a spring (20)-loaded rod 19 which is urged into contact with the arm by the interengagement of a lever 18 attached to the disc 17 and a rocker 21 pivotally mounted at 22 on the drier structure and, at 23, on the rod. As the lid is closed a spring 10 is compressed and a lever 12 moves into the dot-and-dash position shown to wind the mechanism 11 which then moves the disc 17, Fig. 4, clockwise to a position which frees the arm 24 to permit motor operation on depression of the button 16 after the rod 19 has been moved by the spring 20 to engage a rod 9 and thus lock the lid in the closed position. When the mechanism is about to stop the disc 17 contacts the arm 24 to move the button 16 to switch off the motor 3. Simultaneously the brake 4 acts and the lever 18 moves the rocker 21 to retract the rod 19 from the rod 9 in order that the spring 10 may raise the lid. In another construction the lid 6, Fig. 6, carries a notched plate 25 co-operating with a notched plate 26 carrying a pin 33 and connected with the mechanism 11 through a winding-shaft 35 whereas the switch 15 is controlled by the mechanism through a cam (not shown). Above the plate 26 is a spring (29)-loaded claw-like member 30 having long and short claws 30<SP>1</SP>, 30<SP>11</SP>, on a shaft 28 movable by a thumb-piece 27. When the lid is closed the notches 251 and 26<SP>1</SP> are aligned so that the mechanism may be set by turning the piece 27, shaft 28 and the long claw 30<SP>1</SP> which entrains the pin 33. As the mechanism is about to stop the switch 15 stops the motor and soon thereafter-when the basket 1 is at rest-the mechanism stops, leaving the notches 25<SP>1</SP>, 26<SP>1</SP> realigned to allow opening of the lid. Through the action of the long and short claws 30<SP>1</SP>, 30<SP>11</SP>, and the pin 33, by whatever amount the mechanism is re-set in the course of its operation by actuation of the piece 27, the safety interval between switching " off " the motor 3 and the final stopping of the basket 1 is preserved.
