Abstract: A heater control system, particularly for temperature unbalance arising in the currents flowing in three heater elements supplied from a three-phase power supply. The current unbalance may be created as a result of a short-circuit, or may in a temperature control circuit be dependent on changes in the resistance of one heater element having a different temperature coefficient from that of the other elements.

Abstract: A means of injecting tree trunks with preservative fluids comprises using a flexible conduit which is positioned around the trunk covering a slot cut in the trunk. Pumping means pass the fluid under pressure via an inlet and an outlet in the conduit and into the trunk via the slot. The pressure of fluid in the conduit coupled with the flexibility of the conduit effects a seal between the conduit and the slot thereby preventing escape and loss of the fluid.

Abstract: Apparatus for detecting fall of inflation pressure in a pneumatic tire comprising a first coil mounted on the wheel and closeable by means of a pressure responsive switch, and a second coil non-rotatably mounted on the vehicle and having a magnet located at its centre, the second coil being attached to an amplifier and warning device. On fall of tire pressure the switch closes the first coil so that in passing close to the magnet a current flows in the coil creating a magnetic flux. This flux associated with the first coil induces a signal in the second coil which after amplification actuates the warning device.

Abstract: A rim for a pneumatic tire comprises two rim parts. The first rim part consists of a rim flange and associated bead seat and a radially inwardly extending attachment flange portion adjacent the toe of the bead seat. The second rim part consists of a bead retaining flange positioned at one side and a radially inwardly extending attachment flange at the other side with a flat rim base portion positioned therebetween. The two rim parts are secured together with a sealing ring sandwiched between them, the sealing ring extends continuously around the joint between the rim parts and projects radially outwardly in order to engage an adjacent tire bead thereby resisting axially inward movement of the bead from the bead seat.
