Title: Rotary crusher oversize safety device - has piston positioned behind release flap and automatically operated by hydropneumatic circuit
Inventor: RIU HERVE
IPC: B02C13/31
Filed: 1976-02-12
Abstract: A rotary crushing machine has a flap(2a) alongside its rotor (10), to swing about a hinge point (22) at the top, with a piston (26) mounted behind it. The piston housing is connected by a line (28) to a hydro pneumatic accumulator (30) via an electromagnetic valve (36) This is located one side of the pump (31). When an oversize block enters the crushing chamber (19) it pushes the flap down against a spring (46) also behind the flap, and also pushes the piston back. This causes a non return valve (32) in parallel with the pump to close, and pressure rises until a switch (40) is closed to operate a device which in turn operates the valve (36) to isolate the accumulator (30) and to shut down the crusher. The weight of the block swings the flap back fully, falls through, and the spring (40) returns the flap.

Title: Heat exchanger contg. pairs of coaxial tubes and double tube-plates - which minimise perforation effects and maintain good heat transfer
IPC: F28F9/02
Filed: 1976-04-09
Abstract: A shell-and-tube heat exchanger incorporates pairs of coaxial tubes, the adjacent ends of the tubes being fixed in two tubes plates which are near to one another. The outer surface of the inner tube of a pair is in close contact with the inner surface of the outer tube of the pair. The two tube plates are sepd. by a closed space connected to the atmos. by a fluid outlet orifice. Close contact between the tubes is achieved by pumping a liq. at high press. into the inner tube when they are being assembled. The press is 10-120 megapascal, pref. >70 megapascal. Accidental perforation of a tube by e.g. corrosion does not cause communication between the fluids in the shell and in the tube. The close contact between the tubes maintains good heat transfer, equivalent to that in a homogeneous tube. A leak causing fluid to escape to the atmos. would be detected by an indicator, or visually.

Title: Drive for loom with projectiles in closed circuit - ensures acceleration of propulsion discs before weaving elements move
Inventor: MOESSINGER ALBERT
IPC: D03D47/24
Filed: 1977-10-14
Abstract: Loom in which the weft is inserted by >=1 projectile travelling without stopping in a closed circuit one section of which is circular, with, in this section a rotary disk for energising the projectile, is started and stopped according to a new technique. When the loom is stopped, the projectile is immobilised at a point in its closed circuit, before it enters the circular section in which the propulsion disk turns, independently of the stopping of the latter. When the loom is started up, after the propulsion disk has reached its normal speed, the driving shaft of the weaving elements is energised, and simultaneously the projectile is released. Arrangement ensures that when the loom starts up, the propulsion disk has accelerated sufficiently to propel the projectile through the shed and to start the sequence correctly.
