Patent FR-2255033-A1 (FR)
Title: Variable volume shower cabinet with sliding walls - has reversible wall panels with asymmetric returns at top and bottom
IPC: A47K3/32
Filed: 1973-12-19
Abstract: Shower cabinet of adjustable volume, features wall panels with horizontal returns of the same direction at top and bottom, with one return of double the width of the other inversion or 180 deg. rotation of panels, thus effecting a change in volume of the cabinet. The horizontal returns terminate in further outgoing vertical returns which locate in grooves on the periphery of the cabinet base, thus providing the means of fixation of walls to base, enabling the wall panels to slide to form doors and eliminating the need for curtains etc. The base is also rebated peripherally to obviate water escape and the design enables supply or outlet pipes with pumps etc to be located on either side.

Patent FR-2279016-A1 (FR)
Title: Joint for pressurised pipes - with pipe pushed into junction and serrations or holes for security and sealing
IPC: F16L47/32
Filed: 1974-07-17
Abstract: The joint is for internally pressurised flexible pipes, the pipe (2) being pushed into the junction piece (1) rather than on to it. As a result, the internal pressure tends to increase the friction and seal between the pipe and junction instead of causing separation. Additional security may be achieved by forming matching serrations (10, 11) on the mating faces. Alternatively, holes (14) in the junction piece allow the pressure to force the tube outwards locally and form projections which prevent axial movement. Conventional O ring seals (28) may also be included in the joint. The pipe may be made of natural or synthetic rubber.

Title: Extrusion or injection of thermoplastics - by efficient combination of an extruder and independent pumps
IPC: B29C48/38
Filed: 1974-12-13
Abstract: Combination of an extruder, heated accumulator holding molten resin at a pressure of 10 bar and a manifold supplying melt via one or more gear pumps to an equivalent number of moulding or extrusion dies (L). Separate preparation of a homogenised melt and the continuous or intermittent delivery of the melt to obtain a particular product shape allows the temps. and pressures to be optimised for each purpose. The overall energy consumption may be considerably reduced, e.g. from a 45 metric horsepower extruder producing polyethylene pipe to a 10 metric horsepower plastication extruder plus a 2 metric horsepower pump to produce an equivalent profile. Selected groups of pump-fed units may be fed from one extruder kept running under optimum conditions.

Patent FR-2269699-A1 (FR)
Title: Helical turbulence generator for heat exchanger tubes - is made from helically twisted straight long strip
IPC: F28F13/12
Filed: 1975-04-21
Abstract: The turbulence generator is made by helical twisting of a long narrow thin strip of material, and is fitted into a heat exchanger tube for improving heat transfer as a relatively simple and effective passive turbulence generator. The helix diameter is up to three percent smaller than the inside diameter of the enclosing tube. The ratio of the helix pitch and the diameter of the helix is between two and five. The strip thickness is about one to fifteen percent of the helix diameter. For approximately equal heat transfer performance, this helical strip causes an appreciably lower pressure drop than observed on using different internal fittings. The helix is not centered by additional components in the tube because the flow itself centers it correctly.

The recesses and cores are pref. trapezoidal. The anchoring means pref. consists of a threaded bolt (14) passing through the outer wall and ending in a hook which engages an anchoring pin (13) which projects into a groove (12) in each core.

Title: Fuel changing esp. for pressurised water reactor - parts of fuel element skeleton stored and re used for new element
IPC: G21C3/334
Filed: 1975-09-09
Abstract: A method of fuel supply for a nuclear, esp. pressurised water, reactor, to be carried out inside a containment building, utilises fuel elements constitutes of rods in clusters, without a surrounding casing; the rods are mounted on a fuel element skeleton, of which at least some parts, esp. the head-piece and/or foot-piece can be detached when the element is removed from the reactor and can be re-used for a new element. Pref. the head and foot-pieces are stored inside the reactor building for re-use after removal, other substitute components being used for transporting the elements when outside the building; other substitute components can be used inside the building, e.g. for cooling pond handling which are simpler than the components for handling inside the core. Since the only components to be detached are relatively small and there is no surrounding casing, they can be removed and stored inside the reactor building (which is not practicable with casings) for re-use; thus the operation of re-fitting them to new fuel elements is not in the critical path of fuel changing. The only non-fuel components to be removed from the building are the skeleton with its substitute components.

Title: Ultrasonic detection of blood vessels - uses Doppler effect by emitting continuous ultrasonic waves with given repetition
Inventor: BOURNAT JEAN-PIERRE
IPC: G01S15/52
Filed: 1975-09-15
Abstract: The method of rendering the state of blood vessesl visible by ultrasonic waves using the Doppler effect is carried out by emitting continuous series of ultrasonic waves with a given repetition frequency. The reflected signal is mixed with a reference signal have the same frequency as the ultrasonic waves, to produce a Doppler signal for different propagation times of the ultrasonic waves. The Doppler signal is subjected to detection with a large bandwidth, and the signal corresponding to the preceding series of waves is derived from the signal corresponding to each series of waves emitted. The number of passages of the subtraction signal is determined in the time unit above a given threshold for each propagation time.
