Abstract: 1305859 Seaming non-metallic sheet material COSDEN OIL & CHEMICAL CO 19 April 1971 [24 March 1970] 23667/71 Headings B5K and B5N Two flat plastics surfaces 24, 26 are superposed with particles 28 of a thermoplastic polymer positioned therebetween and are welded together by the application of sonic vibrations thereto at a point near the joint to be formed . The thermoplastic polymer must be heat-sealable to the surfaces. The sonic vibrations are of a sufficiently high frequency and are applied for a sufficient time to melt the particles 28. In examples, (i) high impact polystyrene particles are moulded into a disc and a bar which are sonically welded in face-to-face contact with polystyrene particles sandwiched therebetween; (ii) high impact polystyrene particles comprising polystyrene graft copolymerized with six per cent by weight of high cis transpolybutadiene rubber are moulded into a disc which is sonically welded to a cellulose butyrate sheet with polystyrene particles sandwiched therebetween; (iii) two polyethylene sheets are sonically welded with polyethylene particles sandwiched therebetween, and (d) acrylonitrile butadiene styrene polymer sheets are sonically welded using particles of the same polymer sandwiched therebetween.

Title: Cephalosporins prepn - by heating penicillin ester s-oxides with lewis acids
IPC: C07D501/10
Filed: 1972-04-14
Abstract: Prepn. of cephalosporins of formula (I): (where R1 is H, alkyl, phenyl, phenoxy; R4 is NH2 or R2 where R2 is H, alkyl, halogen, azido or a protected amino group) by heating a penicillin ester S-oxide of formula (II): (where R3 is part of an ester group) in presence of a Lewis acid to give a cpd. of formula (III): which is then hydrolysed to the free acid. Penicillins are converted into cephalosporins which do not give rise to allergies in patients who are hypersensitive to penicillins.

Title: Warp movement - using electrical charge to each warp together with magnetic field
IPC: D03C3/20
Filed: 1972-04-17
Abstract: By switching the polarity, the warps are moved upwards or downwards, selectively, to create the shed for the shuttle to insert the weft giving the required pattern in a finely-woven fabric where the warps are densely packed. Alternatively, the nose of the shuttle can be used to exploit the magnetic field and deflect the warps upwards or downwards according to pattern requirements.

Title: Mixing of fluids by jets impinging on films - useful for liqs. and gases, giving very homogeneous mixts.
IPC: B01F5/20
Filed: 1975-02-18
Abstract: Fluids are mixed by giving the prim. fluid a flow in the form of a thin film and the sec. fluid a flow in the form of a number of jets. The jets of sec. fluid come into contact with the film of prim. fluid at an angle and pressure dependant on the nature of the fluids, and at a speed such that the sec. fluid is dispersed in the prim fluid. The film of prim. fluid may be cylindrical or conical or in the shape of parallel truncated cones or plane parallel curtains, and the jets of sec. fluid may be at right angles or inclined in the form of inverted truncated cones, or in series in parallel planes. A third fluid may be introduced at the point of impact. The appts. incorporates a mixing chamber with means of forming the film and the jets, and of feeding the fluids and discharging the mixt. The process is simple and is applicable to liqs. and gases, giving a very homogeneous mixt. of different fluids.

Title: Machine press makes discs to cover pop corn roasting plates - from coiled sheet material which is blanked, pressed and spun
IPC: A23L1/18
Filed: 1975-05-06
Abstract: A machine press is claimed which uses sheet material, such as aluminium foil, from which it blanks out and forms cover discs for the parching plates of pop-corn roasters; discs produced on the press are also claimed. The sheet material is advanced intermittently as required from a supply coil; the feed mechanism is powered by a double-acting, pneumatic cylinder with its piston connected to a crank on a ratchet, chain wheel driving feed bands which sandwich-grip the edges of the sheet material, carrying a new area of sheet between vertically-faced punch and die and then pausing. The movable punch and fixed die are set coaxially on horizontal axis and the punch is moved by a double-action pneumatic piston; the punch face has an annular shear blade to blank out the disc and the punch and die faces are profiled to produce a desired configuration on the disc surface, by a simple pressing operation alone if required. The feed bands carry the punched waste sheet away from the press station after the disc is cleared. Used in the mfr. of sheet material cover discs for the parching plates on which maize is burst in pop-corn roasters. The machine offers the facility of producing discs by a simple, single stroke pressing operation with spinning if required.

Title: Control position indicating device - uses coloured lights to show selected position to motor vehicle driver
IPC: B60H1/00
Filed: 1976-01-28
Abstract: Motor vehicles have numerous controls, many of which are illuminated by a light which must be visible by day, but not overpowering by night. By using a multicoloured display, the driver can not only see the control, but can tell from the colour what position it is in. A number of different configurations are described, including one in which a single light source illuminates the keys of a keyboard control unit. The principle of operation employs a different coloured filter (3a, 3b) interposed between the light source (1) and the screen (2) for alternative positions of the control.
