Title: Clip for trim attachment to sheet materials - has inclined surfaces of hook engaging edge of hole in sheet
IPC: F16B21/08
Filed: 1974-01-24
Abstract: The clip body (10) carries the exterior head or cable clip, with a sealing face (10a) attached by a part cylindrical section (30), of height less than the thickness of the supporting sheet (T), to the spring foot (24). This foot has partially conical faces (22, 26) which bear against the interior of the hole when inserted. As the spring arm (23) tries to open, the conical faces cause the sealing face (10a) to be drawn against the support sheet face (Fe). A good sealed joint is therefore always maintained even though the material thickness (e) may vary over a wide range. Control over insertion forces is gained by varying the slope and concavity of the faces (21a, 23a) whilst similar control of extraction forces is given by the slope of faces (22, 26).

Title: Continuous sterilising and cooling appts - for foodstuffs and pharmaceuticals in containers
IPC: A23L3/04
Filed: 1974-02-11
Abstract: The appts. is for prods., such as preserved foodstuffs, various drinks and notably milk, and pharmaceutical prods. all of which can be treated under hydrostatic press. and comprises and endless conveyor, carried over pulleys and passing successively through a column of increasing press., a sterilising column and a decreasing press. column. The total press. in the sterilising column is balanced by the height of the hydrostatic columns whose upper level is maintained constant by water overflowing from the columns, while the lower level is kept constant by a float valve which regulates the admission of compressed air through a hole in the sterilising column. A circulating pump takes water from the base of the sterilising column and delivers it through outlets at the top of this column; on the way it passes through a heater fed with steam. The steam admission is regulated by a float valve and the float chamber is connected with an auxiliary enclosure situated inside the sterilisation column; it receives a small portion of the water circulated by a pump and brought up to the sterilisation temp. by the heater. If the water temp. falls, the level rises and with it the float; this opens the valve to admit more steam so that the temp. of the treatment water will increase. The method of regulation offers precision, simplicity, trouble-free operation and robustness with ease of working and maintenance.

Title: Change-over system for forging dies - on horizontal, hydraulic forging press using multi-die holders
IPC: B21J13/08
Filed: 1974-09-06
Abstract: This change-over system for forging dies held in a multi-die holder is designed for automatic operation, i.e. without stopping the press or manual assistance. The die holder has a keyway in the centre of its base and a key extends beyond the base of the holder in line with it. The set up is designed, so that when the piston is at the end of its return stroke, the die-holder can be changed by being guided in the key-way slot. The die-holder is clamped in position by holding down rails which are spring-loaded through suitable holding down bolts. These are also released by suitably located cylinders which can be operated when the press is at the top of its return stroke. Die-holder is kept in position by suitable wedge shaped recesses into which suitable plungers fit.

An auxiliary shuttle weaves a decorative froup of yarns or rovings into this loop to form a decorative loop and these decorative loops are tied together by elasticated warp yarns. A novel edging tape is produced.
Patent FR-2257089-A1 (FR)
IPC: G01N33/543
Filed: 1975-01-02
Abstract: To determine reactive biological particles on a substrate, the latter is first loaded with a monomolecular layer of specific biological particles in a special pattern. The solution which is suspected of containing the particle which is biologically active towards the first particle and which is to be determined is now added to this substrate. If this particle is present, it becomes linked to the first layer on the substrate to give a bimolecular layer. Subsequently, the same substrate is contacted once more with a solution which becomes biologically linked to the particles to be determined and is radioactively labelled. After the substrate has possibly been washed off it is now possible to determine by known methods the difference in radioactive emanation between the loaded part of the substrate and the uncoated part. The method can also be used to determine immunological activity of specific particles. On addition of such particles to the solution which is to be investigated, the layer formed on the substrate has a radioactivity which is zero or very greatly attenuated depending on the immunological activity of these particles with respect to the particles to be determined.

Patent FR-2280661-A1 (FR)
IPC: C08J9/14
Filed: 1975-07-22
Abstract: Urea-formaldehyde resin solutions are foamed, optionally using additional blowing agents. During the polycondensation reaction of the urea-formaldehyde, which is still of low molecular weight, to give the amino resin, an exothermic, gas-releasing reaction takes place during the foaming process, initiated by the catalytic decomposition of hydrogen peroxide by means of peroxidases. The foams produced in this way have high strength values, as required by the construction industry, and in addition have high densities.

Title: Cable cutter for aero spatial use - has flexible plug in cylinder forming seal between cutter and pyrotechnic charge
Inventor: CABRIERE JEAN
IPC: F42B3/00
Filed: 1975-08-01
Abstract: The cable cutter is intended for aero spacial use and comprises a cylinder (1) with one end closed. The cable (4) passes through this, resting on an anvil (3) and has the cutter blade (5) above. This is sealed by a flexible plug (6), rubber or plastic, fitted on top of the cutter and firmly gripped by the cylinder walls. A hammer (7) and pyrotechnic charge (2) is positioned above this, a space being left above the plug. Firing the charge drives the hammer onto the plug.

Title: Heart rate meter based on heart muscle contractions - uses two injection electrodes and two scanning electrodes
IPC: A61B5/053
Filed: 1975-08-07
Abstract: The heart rate and rhythm meter has four electrodes fitted to the patient being monitored. Two are injection electrodes applying a high frequency current. The other two are scanning electrodes between the first pair, coupled to a detector, filter and shaping channel for the rheographic signal. This channel is coupled to a heart rate counter.
