Abstract: Trailer having a plurality of ground wheels (20), a towing connection (70) and means for preventing (80, 81) or indicating unreadiness for use of the connection unless the trailer is in a towing condition. The ground wheels (20) may be retractable relative to a floor structure (13) from respective operative positions from which they transmit the weight of the trailer to the ground to enable it to be transported, to respective inoperative positions in which the weight of the trailer is transmitted to the ground at least primarily by supporting means other than said ground wheels (20) and in this case said towing condition is when the wheels (20) are in their operative position. 
     Alternatively or in addition the trailer may have a tail gate lift said towing condition in this case being when the tail gate is secured in a raised position.

Abstract: This disclosure relates to a self-sealing pneumatic tire (10) with puncture sealing properties and a method of manufacturing such a tire. The puncture sealant properties of the self-sealing tire are provided by a layer (15) comprised of a blend of a crosslinked polymeric material and an irradiation degraded polymeric material. The method of this disclosure comprises providing a layer (15) of rubber compound with a blend of polymeric materials, one of which degrades upon exposure to irradiation and another which crosslinks either on exposure to irradiation, by chemical reaction at vulcanization temperature, or both, assembling the layer into an unvulcanized tire in situ with the polymeric materials unaltered, vulcanizing the tire without altering the degradable polymeric material and irradiating the tire whereby the degradable polymeric material is degraded to a low viscosity to form a tacky material and the crosslinkable polymeric material is crosslinked to form an elastic matrix for the degraded polymeric material, whereby the layer has puncture sealing properties.

Abstract: The invention provides a basic door message recorder in the form of a microphone (14) and switch (18) fixed adjacent the door of a building to be accessible from outside the door, together with a tape recording device (20) which is rendered operable by operation of the switch to enable a caller to record a message on the tape. Modifications provide for messages from an occupant to be played back to a caller and for the recording of messages selectively for the occupants of a multiple occupation building. A practical arrangement (Figure 6) for the latter purpose employs a processor (72), memory (74) and address register (76) in conjunction with a tape recording device (70), which processing system is used to enable a message recorded for a particular occupant to be distinguished from messages recorded for other occupants. In a modification (Figure 7) of the last mentioned arrangement, the processor (94, 96, 98) is incorporated in an internal telephones system to provide a message recording facility therein.
