Title: Process for forming film of hydrolysed ethylene-vinyl acetate copolymer
Inventor: IWANAMI TERUO
IPC: C08J7/048
Filed: 1984-02-08
Abstract: A process for forming a film of a hydrolysed ethylene-vinyl acetate copolymer containing 25-55 mole % ethylene comprises coating a substrate with a solution of the copolymer in a mixed solvent of (a) water; (b) at least one member selected from propyl alcohol, butyl alcohol and benzyl alcohol; and (c) at least one member selected from formic acid, an alkyl formate, acetic acid, an alkyl acetate, dimethylsulfoxide and N-methylpyrrolidone, components (a), (b) and (c) being present in specified proportions. The process can be carried out at normal temperature employing a solution having a low concentration of the copolymer. Also, the process does not need any additional operations or special devices and produces an even and homogeneous film of the copolymer which has excellent properties such as transparency and gas impermeability and is suitable for wrapping or packaging.

Title: Co-extrusion die assembly for a cooker extruder
Inventor: VINCENT MAURICE
IPC: A23P30/25
Filed: 1984-08-09
Abstract: A co-extrusion die assembly (4) for extruding a tube of cooked material around a filling is fed under pressure from a cooker extruder (1) with cooked material which passes through the die (4) along a passage to an outlet (5). A filling tube (6) with internal surface of low coefficient of friction follows a straight path through the die passage (3). The straight path avoids heat degradation of the filling that otherwise occurs with a filling tube extending along a path e.g. turning through 90 DEG , that is not straight. A plurality of passages and filling tubs may be provided in a single die (Fig 2), the passages each having an outlet parallel to a single inlet from the cooker extruder, with intermediate passage parts extending at an angle between the inlet and the outlets. <IMAGE>

Title: Lining pipe connections
Inventor: YARNELL IAN ROLAND
IPC: B29C65/00
Filed: 1984-09-28
Abstract: In a method of lining the junction between a lined sewer main (3, 4) and a lateral branch pipe (5) a sleeve (2) of hardenable plastics material is inserted into an aperture in the lining (3) under remote control by an inflatable carrier (1) supported on a traveling carriage in the interior of the main (3, 4). When the carrier (1) and sleeve (2) are in position, the carrier (1) is inflated to expand the sleeve (2) and force it against the edge of the lining (3) and the end portion of the branch pipe (5) where it seals off the annular space 8 between the lining (3) and the original wall (4) of the main. The sleeve (2) may be of a fibrous material saturated with a resin, and the carrier (1) may be heated to assist in curing the resin. Once the sleeve (2) has set, the carrier (1) is deflated and withdrawn. <IMAGE>

Title: A baffled air intake system for outboard motors
Inventor: FERGUSON ARTHUR R
IPC: F02B61/04
Filed: 1985-03-04
Abstract: The outboard motor includes an engine driving a propeller. The engine cover includes an upper dome-like cover 22 sealingly connected to a lower pan-like cover. A combustion air opening 32 through the upper portion of said upper cover 22 has a partition 36 inside the opening requiring entering air to travel upwardly into a chamber 28 between a baffle 26 and the inside of the upper cover 22.

Patent GB-2177786-A (GB)
Title: Refrigeration method and apparatus
Inventor: MILLER JEREMY PAUL
IPC: F25B40/02
Filed: 1985-07-10
Abstract: In a mechanical refrigeration apparatus of the vapour compression kind, comprising a compressor 2, condenser 4, expansion valve 6, and evaporator 8, a sub-cooler 12 is employed to reduce the temperature of the condensed refrigerant to a value at which at least 90% by volume and preferably all of it remains in the liquid phase on passage through the expansion valve 6. The sub-cooler 12 is cooled by means of a supply of liquid nitrogen from vessel 14. Alternatively, liquid nitrogen is evaporated in a circulating heat exchange atmosphere in the sub-cooler 12. Increased heat load in chamber 10 may thus be met without there necessarily being any increase in the evaporating temperature and pressure. <IMAGE>

Title: Supporting plate arrangement for document printers
Inventor: ELLIS MICHAEL JOHN
IPC: B41J11/20
Filed: 1986-05-23
Abstract: For the accurate positioning of a document relative to a printing head, a document supporting plate arrangement has a thick rectangular plate and carriage which supports and controls the position of this plate. A guiding system ensures accurate horizontal movement of the thick plate between a rearmost position in contact with side members of the carriage and a forwardmost position with the document in contact with horizontally extending plates adjacent to the printing head. Bias means maintain the thick plate in contact with the side members when there is no force applied to the thick plate to move it towards the printing head. A pair of elongate, cylindrical cams mounted between upper and lower frame members of the carriage are simultaneously rotated to apply a force to the thick plate and move it against the bias means towards the printing head. A document sensing arrangement may detect the presence of a document to be printed. Vertical adjustment of the supporting plate arrangement relative to the printing head may be by rack and pinion or by screw and keyed-rod arrangements. <IMAGE>

Title: I.C. engine fuel supply system
Inventor: TIMMS COLIN THOMAS
IPC: F02M37/20
Filed: 1986-06-10
Abstract: A low pressure pump 14 supplies fuel to a high pressure pump 10 by way of a conduit 12. A reservoir chamber 18 has an opening from its lower end to the conduit the opening incorporating a spring loaded valve member which in normal use remains closed. A passage 25 connects the conduit with the upper portion of the chamber and from the upper portion of the chamber extends a cylindrical vent pipe 20 in which is slidable a piston 22 which defines a small clearance with the vent pipe. In the event of the low pressure pump pumping air due to fuel starvation and the engine stopping, the piston descends slowly and opens the valve to allow the fuel contained in the chamber to flow into the conduit thereby allowing the engine to be restarted.   <IMAGE>

Patent GB-2181796-A (GB)
Title: Improvements in or relating to rotary shaft seals
Inventor: DOLMAN SAMUEL
IPC: F16J15/34
Filed: 1986-10-06
Abstract: A shaft seal arrangement is provided for a mixing device in which paddles (10, Fig. 10) or the like are mounted upon a shaft 6 driven externally of the device and thus passes through a wall 8 thereof. The seal comprises a first and a second member 22, 24 of a face seal arrangement which members are spring-biased together. The second face seal member 24 is secured to a first labyrinth seal member 30 which interleaves with a second labyrinth seal member 36. Lubricant grease is charged to the labyrinth seal members under pressure and normally does not enter the face seal stage. If, however, ingress of material being mixed forces the two face seal members apart, grease from the labyrinth stage enters the space between the face seals and is driven outwardly of the confronting faces along a spiral groove (42, Fig. 3) in one of the face seal members, so that the grease and material is ejected from the face seal. <IMAGE>

Title: Air/fuel ratio sensing apparatus
Inventor: MASKELL WILLIAM CHARLES
IPC: G01N27/416
Filed: 1987-08-14
Abstract: The apparatus, which measures oxygen in the gas after combustion comprises a sensor having a pseudo reference chamber B and an amperometric chamber A, separated by solid electrolyte wall 1 and each having a further solid electrolyte wall 5,6 and a diffusion barrier 3,4. The gas in chamber B is normally maintained at a higher air/fuel ratio than the external gas by oxygen pumping current I2 and the current I1, flowing through dividing wall 1 due to applied potential 20 is a measure of the air/fuel ratio. Various operating arrangements are described. The output of current drive unit 21 may be controlled so that I1 and I2 is held constant. Alternatively, the voltage across wall 1 may be held constant by driving a current across wall 5 to pump oxygen out of chamber A. In another alternative, the pump current I2 is applied, the current due to a fixed voltage across wall 5 is measured and the EMF across wall 1 determines whether the mixture is rich or lean. A further alternative dispenses with the pump current I2 but makes barrier 4 more restrictive than barrier 3. <IMAGE>
