Title: Servo controlled micro flow discharge valve - has diaphragm acting against spring on stem connected to conical valve head through metal hinge links
Inventor: LEGRANDGERARD JEAN
IPC: F16K1/32
Filed: 1975-09-19
Abstract: The conical valve head (14) seats on the bore of a bush (13) mounted on the axis of the flow passage (2,4) in the body (1) and is fixed on the end of a lever arm (15). A disc (17) supports the arm at right angles to the flow line and a seal between the two is formed by a thin central cap (22), allowing the arm some small swinging movement. The main supports between arm and disc are formed by two metal hinge links connecting the disc to another (18) fixed to the arm a little further along. Beyond the second disc the arm is extended (8) within the actuator chamber. Servo fluid pressure on a diaphragm mounted in the chamber transmits a lateral force to the end of the arm, the force being resisted by a return spring (32) mounted between the end of the arm and the support disc.

Title: Incremental movement control of plotting table axes - uses controller producing number of pulses proportional to movement required
IPC: G05B19/4103
Filed: 1977-03-16
Abstract: Small elements of incremental movement in two axes of a plotting table are provided in binary form by a controller which produces pulses whose number is proportional to movement to be made. Output of a clock generator (3) is applied via a switch (10) only during displacement time. The clock signal is applied to pulse rate modifying circuit (11) which in turn drives other identical circuits (4, 5) to provide variable frequency signals (Fx, Fy) proportional to incremental movements (DELTA x, DELTA y). Clock output is divided (12) down for a counter (13) which drives a decoder (14) whose output constitutes lines (15) of a programming matrix (16). The columns (17) are connected via gates (18) to binary inputs on the pulse rate modifying circuit (11). This provides movement speed information.
Patent FR-2348792-A1 (FR)
IPC: E01C19/52
Filed: 1977-04-20
Abstract: The boundary is formed by means of kerbstones made of concrete. The kerbstones laid in a row on the roadway surfacing are fastened in the surfacing with nails (26). The nails are present in a row in a kerbstone shoulder (12). The latter has a passage opening for each nail (26), which opening opens in the bottom of a conical recess (24). Cast into the passage opening for every nail is a sleeve (22) which is made e.g. of a plastic. When the nail (26) is driven in by means of a hand hammer, the concrete material is not affected because of the recess (24). The nail is furthermore, as a result of a tight fit in the sleeve, guided by the sleeve during driving into the surfacing. Bending of the nail and crack formation on the shoulder (12) are prevented. The base area (14) of each kerbstone can thus be reduced. The driving in of the nail can take place with a tool which is provided with a conical tip which fits into the recess (24). As a result, the tool is correctly aligned during driving in of the nail and the nail can be guided through a channel in the tool tip or through a shell-shaped recess of a striking pin guided in the channel.

Patent FR-2357742-A1 (FR)
IPC: F02F7/00
Filed: 1977-07-01
Abstract: The oil sump comprises an intermediate frame (4) connectable to the crankcase and a sump body (8). The intermediate frame (4) and sump body (8) each have a flange (12, 15) and are connected by a rubber-elastic cord (19) bearing on these flanges. The flanges (12, 15) overlap. The flange (12) of the intermediate frame (4) has a section (13) inclined towards the assigned frame wall and the flange (15) of the sump body (8) a section (16) inclined towards the assigned sump body wall. Each of these sections (13, 16) merges by way of an arched part into the wall assigned to it. The rubber cord is for the most part vulcanised onto the transitional parts. Due to the improved lateral guiding of the sump body (8) the metallic knocking of the sump body (8) against the intermediate frame (4), which occurs in known designs, can be prevented. In addition, the cord (18) is not exposed to inadmissible shear stresses.
