Patent FR-2003142-A1 (FR)
Title: Plastics profile for a window or door frame is bonded
IPC: E06B3/22
Filed: 1969-02-26
Abstract: Plastics profile, especially for a door or window frame is bonded with an internally palced metal profile, e.g. an aluminium profile, with a mainly similar transverse profile, the surfaces of the plastics profile and of the metal profile being at least partly in contact with each other. Plastics profiles for use in door and window frames are normally subject to deformations arising as a result of the action of sunlight, and this prevents a good sealing of the doors or window frames being obtained. The provision of the metal profile within the plastic profile effectively prevents the deformation of the outer plastics profile, by providing good thermal conductivity between the outer and inner surfaces of the profile. The plastics profile pref. consists of PVC.

Title: Bi metallic tubes - with specified properties of inner or outer layers
IPC: C23C6/00
Filed: 1971-08-18
Abstract: Bimetallic or bialloy tubes composed of different layers with different mechanical props. can be centrifugally cast from a wide range of alloys, e.g. Cu, Cu alloys, Cr, Ni, Fe base alloys and alloys contg. Al + Si. Gas or slag protection is used to prevent the formation of oxide films on the solidifying surface of the primary cast layer before casting of the inner layer. This results in good jointing. An adjustable splash cap is also detailed which is used to compensate for the contraction on solidification of the primary layer and prevent material from the secondary layer reaching the outer surface of the tube. Tubes with high strength inner layers and corrosion resistant outer layers, etc., can be thus cast.

Braking is proportional to spring force and causes the road wheels to rotate at the same speed.
Patent FR-2265170-A1 (FR)
Title: Thermal circuit-breaker trip - has freely deflecting bimetal strip operating trip at set deflection
IPC: H01H71/14
Filed: 1974-03-20
Abstract: The bimetal strip (6) in this circuit-breaker deflects on overload and touches a contact (10) that causes it to shunt a trip coil (15). Whilst deflecting, the strip remains in circuit due to flexible connections. The current flow in the strip creates a voltage that operates the trip coil as the contacts touch. Severe overloads cause a direct acting trip (22) to operate the circuit breaker and protect the bimetal strip contacts. A differential magnetic transformer may be used instead of a shunt coil. As the bimetal strip is not linked to the trip mechanism it does not creates the difficulties usually found with low-current circuit-breakers such as poor regulation and uncertain operation.
