Title: Precast concrete paving slab - has stepped edge to form top edge cap obviating corner chipping
IPC: E01C11/22
Filed: 1976-02-03
Abstract: The precast concrete paving slabs have a stepped edge to obviate the chipping of the upper surface edges. At least one of the vertical edges of the slab has a right angled stepped projection. The projection may extend over the lower third of the slab edge, and presents an offset lower vertical face. The slabs are installed with a stepped edge a butting a plane vertical edge, thus, forming a gap between the abutting top edge zones. The slabs may, thus, settle and rotate without the upper corners coming into contact and chipping.

Title: Electropneumatic control of braking force for railway vehicles - uses Wheatstone bridge to control differential amplifier comparators and then brake cylinder feed valves
IPC: B60T13/66
Filed: 1976-07-16
Abstract: The electropheunmatic circuit is for the control fo braking force, particularly on railway vehicles and it applies particularly to an electric regulator based on a normal Wheatstone bridge with one resistance representing the brake force and another the pressure. The centre of the brake force resistance is connected to an operational amplifier and of the pressure resistance to the negative of this amplifier. The amplifier output is joined to two comparators in turn connected to amplifiers and these feed coils of electrically operated valves. These valves control the supply of compressed air to the brake cylinders and the control is both sensitive and rapid acting.
Patent FR-2319827-A1 (FR)
IPC: E03C1/10
Filed: 1976-07-26
Abstract: The housing of the anti-siphoning device is composed of a lower housing part (1) with a supply connecting stub (2) and of an upper housing part (6) with a discharge connecting stub (5). A plate (7), clamped in a sealing manner between the housing parts, has a channel (12 to 17) which runs in the form of an S and connects the two connecting stubs to each other. A valve body (4) loaded by its weight and the line pressure normally closes an air inlet (8) to the channel via a valve seat (3). When a subatmospheric pressure prevails in the line, the valve body (4) is raised from its seat (3) and aerates the discharge side of the line. At the same time, it closes the S-shaped channel (12 to 17). This prevents dirty water from being sucked out of the discharge line when a subatmospheric pressure prevails in the supply line. Due to the throughflow direction (from bottom to top), the anti-siphoning device is suitable for the shower connection of mixer units.

Title: Oil filled cable end sleeve - has retaining tube with coaxial armouring elements interrupted by insulating layers to form series connected capacitors
IPC: H02G15/06
Filed: 1977-09-22
Abstract: The capacitive cable end sleeve has a support tube (6) onto which alternate layers of dielectric (5) and conducting foils (4) are wound. The inner foil (4a) is in contact with the tube (6) at line potential, and the outer foil (4b) is in contact with earth, e.g. through the mounting flange (9). The cable is connected to a central tube (2) running the full length of the sleeve. An outer porcelain (7) covers the whole assembly. As the cable is retained in the centre tube (2) any variations in cable oil pressure are contained within the tube and overpressures do not, therefore, cause high loadings on the porcelain. The latter can thus be dimensioned with regard to sleeve oil pressure only. As the terminal end construction is independent of the cable it can be completed and tested in the factory, and is easily assembled on site.
