Abstract: 1426918 Laminates STANDARD OIL CO 30 April 1973 [9 June 1972] 20425/73 Heading B5N [Also in Division H1] An electronically conducting, ionically insulating current collector or inter-cell connector for a capacitive device (see Division H1) comprises a layer of conductive carbon black loaded elastomer sandwiched between two flexible graphite layers. The graphite layers are each preferably 0À3 tp 10 mils. thick and may have anisotropic conductivity. The elastomer layer may be 2 to 10 mils. thick. The elastomer may be a natural or synthetic rubber, examples of the latter being disclosed, and may include promoters, e.g. nitroso-compounds, to increase its conductivity. The elastomer layer may be applied to one of the graphite layers, optionally as a solution, by calendering, silk screening, spray or brush coating. Alternatively a sheet of the elastomer, prepressed or calendered to desired thickness, is placed between the two graphite sheets. The laminate is consolidated by pressure prior to curing the elastomer by nuclear, ultra-violet or infra-red radiation, steam, hot air or vulcanizing. Comparative examples disclose a single graphite sheet laminated to the loaded elastomer, the latter having a smooth or a roughened surface.

Title: Vacuum, anti-rot timber treatment - enhanced by shock-wave compression of wood to near elastic limit
IPC: B27K3/08
Filed: 1973-09-20
Abstract: Impregnation of wood with a protective liquid esp.

Title: Parallel to series data stream converter - uses three state logic to avoid output distortion due to parasitic effects
IPC: H03M9/00
Filed: 1973-12-27
Abstract: The converter provides a single output of data in series form derived from such data provided in parallel form.

Title: Water filled ash tray - cigarette ends fall into water preventing reignition and smouldering
IPC: A24F19/00
Filed: 1974-10-15
Abstract: The ash tray which automatically extinguishes the burning cigarette ends consists of a cylindrical can-shaped container, partially filled with water and fitted with a lid which has a central conical sunken surface with the lower edge of the cone terminating above the water level, and with a hole through the middle, through which the cigarette ash falls into the water, and through which the cigarette end also passes.

Title: Polyvinylidene fluoride-coated glass fibre panels - for lining chemical tanks, esp. for protecting ships holds against liquid contents
IPC: F16J12/00
Filed: 1975-08-26
Abstract: Protective internal lining for metal tanks or reservoirs comprises a layer of fluoropolymer (I) supported on a fibrous substrate, pref. comprising resin impregnated glass fibre matting. The lining is applied with the assistance of temporary covers and associated strip foam rubber seals which enable the interface between the supported polyfluorocarbon covering and the metal surface to be evacuated. Suction is applied to consolidate the interfacial contact by external atmospheric pressure during spreading and setting of the adhesive. The polyfluorocarbon surface is impervious and resistant to a wide variety of solvents and chemicals, reducing restrictions on the varieties of materials which may be contained without deterioration of the tank. Vinylidene-based resins are easier to apply and cheaper than PTFE or FEP coatings.

Title: Transfer printing textile piece goods, esp. knitteds - blanket pressing on driven heated cylinder has friction coupling drive
IPC: B41F16/02
Filed: 1976-03-31
Abstract: Textile piece goods, esp. knitted fabrics of synthetic fibres are printed by a transfer process in which the goods are brought into contact with the band carrying the dyestuffs, whilst heat is applied, between moving pressing surfaces formed by an endless blanket conveyor travelling round a number of guide rollers,and a heated cylinder. The blanket is driven by a roller positioned at the inlet of the pressing zone and equipped with a friction clutch. The angular velocity of the driving member of the clutch, having regard to the dia. ratio, is somewhat higher than that of the heated cylinder, and the frictional moment of the clutch is set so that it is equal to the moment arising as the sum of all tensile forces set up by friction on the blanket, outside the pressing zone. The heated cylinder and the clutch afe driven by a variable speed motor through a chain transmission. The application is not restricted to transfer printing but suits any similar process in which a blanket runs with the goods. It is easy to adjust the speeds of the blanket and drum if necessary, and the flattening and smoothing effects caused by excessive pressure on the fabrics are ruled out, which is of partic. benefit in the processing of knitted fabrics of textured yarns.

Title: Roller for applying adhesive - has eccentric sleeves to control pistons sliding in holes in roller face to receive and later eject adhesive
IPC: B05C11/10
Filed: 1976-06-08
Abstract: The roller applies adhesive to a surface by means of holes in its face. The adhesive (18) fills the holes (4), the excess being removed by a doctor blade (17). The holes are fitted with pistons (5), forming part of a common back-up sleeve (6, 8). This is joined to an eccentric sleeve (11) by ball races. Another eccentric sleeve (12) fits inside the first and runs similarly on the roller shaft (1). The eccentricity of the sleeves is adjusted by levers. This determines the travle of the sliding pistons and the amount of adhesive deposited. A plastic spring (7) returns the pistons to the bottom of the holes.
