Title: Ball seating and tube joint for nonreturn valve - ball forms accurate seating, joint obtained by simple compression ring
IPC: F16K15/04
Filed: 1974-02-15
Abstract: The valve body (6) has an axial bore (9). At one end of this is an annular rib (10) providing a flat seating for a "Delrin" (RTM) blank (15). A steel ball (16) is forced against this, deforming it and causing the centre to be cut through by the edge of the rib. A residual deformation gives an accurate seating. On the other side of this rib is a washer (11) which is compressed around the circumference of an inserted tube when a cap is screwed down against the projecting surface of a ring (12) held in place, with axial movement, by a clip (13) in a groove (14).
Patent FR-2236683-A1 (FR)
Title: Trailer for muck- and fodder spreading - with sliding support for load and with spreading drum driven by flexible shaft
IPC: B60P1/00
Filed: 1974-07-11
Abstract: The load is pressed out of the trailer by a moving bulkhead and by floor mounted scraping frames with lateral support arms. The frames prevent the load from being compressed and ensure a steady feed to the spreading drum mounted above the frames at the rear of the trailer. the drum is driven from the tractor PTO by a simple flexible drive which eliminates a complicated mechanical linkage. The bulkhead and scrapers are powered hydraulically. The scrapers are spaced off the floor of the trailer to prevent sticking or freezing, while the trailer sides are wooden or insulated for similar reasons.

Title: Evaporator for liquefied petroleum gas - has electric heating element controlled by level of liq. in boiler
IPC: F17C9/02
Filed: 1977-02-08
Abstract: The evaporator for liquefied petroleum gas consists of a reservoir (10) connected by an electro-magnetic valve (16) to the liquid gas supply line (14). The reservoir contains an electric heating element (12) and two switches (21, 23) controlled by floats (20, 22). When the valve is opened, liquid flows into the reservoir until the level is high enough to actuate the upper switch. This switch closes the valve and energises the heating element. When the liquid level falls to the level of the lower switch the valve is re-opened and the heating element switched off. The valve is spring loaded so that liquid can return from the reservoir (10) to the supply line (14) if the level in the reservoir exceeds the safe level.
