Abstract: 1387603 Aminomethylated aromatic addition polymers ROHM & HAAS CO 25 May 1972 [1 Nov 1971] 24627/72 Heading C3P Aromatic addition polymers containing amino methyl groups are produced by reacting an aromatic addition polymer with at least a ¢ molar quantity (per mole of aromatic units in the polymer) of a halogen-free acylaminomethylating agent in the presence of a swelling agent for the polymer and an acidic catalyst, to form the acylaminomethylated derivative, and thereafter removing the acyl groups by hydrolysis to form the corresponding aminomethylated polymer. The acylaminomethylating agent is preferably one satisfying the general formula where R is H, alkyl or aryl or -NY 1 Y 2  wherein Y 1  and Y 2  can be H, alkyl or aryl and the same or different, R 1  is H, alkyl, aryl or hydroxyalkyl and X is where R and R 1  are the same as above, or X is -OZ where Z is H, alkyl, aryl or where R 2  is C 1-18  alkyl or C 6-18  aryl. Examples of such agents are N-methylol acetamide and N-methylol formamide. Examples of preferred swelling agents are nitro-substituted aliphatic or aromatic hydrocarbons, and of the preferred acid catalyst are sulphuric acid or a mixture thereof with at least one other acid. In the examples the following polymers are treated: copoly(styrene / trimethylolpropane trimethacrylate), copoly(styrene / divinyl benzene), copoly(styrene / ethyleneglycol dimethacrylate) and polystyrene. The introduced aminomethyl groups may be alkylated acid, if desired quaternized, and can also be oxidized to amine oxide groups. In Example V the product polymer containing -CH 2 NH 2  groups is reacted with formaldehyde and formic acid to produce -CH 2 N(CH 3 ) 2  groups, which are then oxidized to amine oxide groups with H 2 O 2 . The polymers find use as ion exchange resins.

Filed: 1954-08-25
Abstract: 776,554. Television. GENERAL ELECTRIC CO., Ltd., and BIGGS, A. J. Aug. 22, 1955 [Aug. 25, 1954], No. 24717/54. Drawings to Specification. Class 40 (3). In a colour television system of the kind in which a composite signal including a monochrome portion and an auxiliary colour portion (comprising a phase and amplitude modulated sub-carrier) is transmitted as modulation of a main carrier, the frequency difference between this carrier and the carrier on which accompanying sound signals are transmitted is made equal to NF/M, where F is the frequency of the sub-carrier and N and M are small integers having a valve not greater than ten. This arrangement allows the production at a receiver of a wave of sub-carrier frequency (for control of the synchronous detectors in the colour channels) without the need for transmitting a colour synchronizing " burst " during successive line synchronizing signals.

Title: Improvements relating to gas-cushion vehicles
Inventor: HALL KENNETH
IPC: B60V1/00
Filed: 1963-06-21
Abstract: 1,026,953. Air cushion vehicles. HOVERCRAFT DEVELOPMENT Ltd. June 18, 1964 [June 21, 1963], No. 24821/63. Heading B7K. An air cushion vehicle comprises a hollow wall for downward projection beneath the vehicle body so as to contain at least in part the cushion, the wall being collapsible in an upward direction, means for applying a suction to the interior of the wall to promote collapse of said wall and inlet means for relieving said suction so as to avert said collapse, said inlet means being arranged so that relief of the suction diminishes as the distance between the bottom of the wall and the surface below the vehicle decreases. The bottom surface 3 (Fig. 2, not shown) of the vehicle 4 carries a collapsible corrugated wall 2 enclosing a plenum chamber and formed in its lower surface with a port 6, flexible attachments 7a attaching a flexible ribbon member 7 to said lower surface. The interior of the wall communicates through a port 5 and duct 8 with a suction pump 12, which draws air continuously from beneath the wall through ports 5 and 6. The wall, when a peripheral wall, is supported against cushion pressure by ties 10, and when a compartmenting wall, it is supported on each side by ties 10, 11. In operation, when the member 7 meets an obstacle it is moved upwardly against the resistance of members 7a to restrict the flow of air through port 6, the resulting suction applied to the interior of the wall causing the wall to telescope upwards clear of the obstacle. To assist the wall to return to its extended position a slidable plunger 50 controlled by an actuator 54 and pressure-sensitive device 55 is provided to force the member 7 away from wall 2 to relieve the suction. In a further embodiment (Fig. 6, not shown) the wall 2 is enclosed within a further sealed wall 25 to which member 7 is attached, the cavity between the walls being connected to atmosphere by a duct 27 which extends within the vehicle, thereby reducing the risk of drawing ground debris or water into the system. Ties, such as 10, may support a sealed diaphragm apertured to communicate with the cushion and an injecto pump in the duct supplying cushion air may b used to apply suction to the interior of the wall. A further embodiment embodies a duct for discharging a fluid curtain outside the flexible wall to assist in containing the cushion. Reference has been directed by the Comptroller to Specification 958,996.
