Title: Trigger mechanism for underwater harpoon gun - has double pivot arm setting trigger when harpoon is inserted
IPC: F41B7/04
Filed: 1974-04-19
Abstract: The trigger mechanism for an underwater harpoon gun includes a double armed pivot lever with a link (10) with rounded ends, which in a vertical position, engages a curved groove (15) in the end of the harpoon (14) to clamp it against a fixed member above. The second arm (6) which pivots on the link, fits into a notch (5) in the upper part of the trigger (1). When the trigger is squeezed, it is pivoted back against a spring (4), releasing the pivot lever so that the second arm is swung up as the force of the ejected harpoon swings the link down, against the force of a spring (11) under the second arm (6). When the next harpoon is inserted, it pushes the link down, and assisted by both springs, the trigger is locked again as before.

Title: Device for stacking sheets cut from webs - takeoff roller feeds conveyor running at slower speed
IPC: B65H29/66
Filed: 1974-11-14
Abstract: Automatic cutting and stacking of labels and similar blanks from a continuous strip of material. The material (2) passes over guides (3, 4) and feeds between a cutter (6) and a back-up cylinder (5), which holds the material by suction. The blanks (12) are detached by another suction cylinder (11) and picked up by a takeoff roller (13) having a surface speed approximately 25% greater than the cutter back-up cylinder. The blanks are fed onto conveyors (14, 15) running at a slower speed than the takeoff roller, which causes the blanks to close up and overlap each other. These are then counted (16) and stacked (17). Waste (7) is removed to one side.

Patent FR-2277257-A1 (FR)
IPC: F04D29/66
Filed: 1975-07-01
Abstract: A fan for moving a gaseous fluid, e.g., air, is described in which the high audible frequency noise resulting from the phenomenon occurring at the trailing edges of the blades, known as vortex shedding, is reduced. This is accomplished by notching an edge of each of the blades so that the pattern of vortices leaving the blade, which causes the noise, is disturbed and a turbulence condition engendered. The turbulence distributes the pressure fluctuations resulting from movement of the blades through the fluid over a relatively broad band of frequencies and reduces the annoying noise frequencies. Various notch configurations are disclosed.

Title: X:ray tomography system with collimated beam - uses two stage collimator with parallel plates and has reference level detector
Inventor: BOSSAERT JEAN
IPC: G01T1/29
Filed: 1975-12-19
Abstract: A transverse axis tomograph employs a detector which embraces all the useful radiation beam transmitted from a primary collimator towards the body under examination. This collimator defines the beam for irradiating the body. A rotating anode (3) of an x-ray tube (1) emits a beam (15) towards a primary collimator (10) comprising two stages (11, 12) formed by parallel plates opaque to x-rays. Openings (13, 14) in the plates determine the beam shape (16) for irradiating the body (0). A two stage (21, 22) secondary collimator (20) receives radiation (26) passing through the body for measurement by a detector (8, 9) comprising a scintillator (8) and photo-multiplier (9). Output from this detector is processed (30) with information from a reference scintillator (5) in the primary collimator.

Patent FR-2316525-A1 (FR)
IPC: F16L33/22
Filed: 1976-07-02
Abstract: A method of securing a flange ferrule to the end of a flexible tube having an exterior diameter slightly smaller than the interior diameter of the ferrule, comprises positioning the flange ferrule over the end of the flexible tube and aligning the flange at the end of the ferrule with the end of the tube, placing a flange clamp bushing which has an outer diameter smaller than the inside diameter of the tube into the tube and aligning a flange of the clamp bushing with the flange of the ferrule and, thereafter, expanding the clamp bushing outwardly into engagement with the wall of the tube. Before the outward expansion of the clamp bushing is effected, the clamp bushing and the ferrule are positioned in a matrix which has a receiving cavity with an outline conforming to the flange ferrule and the tube end and the clamp bushing. After the assembly is held in the matrix, a flaring tool or expander is inserted into the bore of the clamp bushing in order to expand the clamp bushing outwardly into the wall of the tube. A flexible tube fitment, comprises the flange ferrule and the flange clamping bushing which has its flange interengaged over the flange of the ferrule and which is forced into engagement with the wall of the tube. Advantageously, an elastically deformable material or bonding material is inserted between the end of the tube and the flange of the clamp bushing. The clamp bushing may be of a length equal to, less than, or greater than, the outside flange ferrule.

Title: Storing solar heat near ambient temperature - using a large tank and a second circuit to generate power
IPC: F24S10/60
Filed: 1976-07-08
Abstract: Process for capturing and storing thermal energy at a temp. close to the ambient temp. The thermal energy is retained in a fluid contained in a tank which is covered by a floating roof made of light thermal insulating material. The fluid in the tank is drawn out from the tank and fed into depressions on top of the floating roof where it either absorbs or gives back energy before dropping back into the tank. By day the heat energy is absorbed and at night it is given back. The appts. allows the storage of heat at temps. near to the ambient temp. The appts. stores thermal energy in the form of calories, collecting them during the hours of exposure to the sun. Electricity is generated.

Title: Treating effluents contg. fats, polysaccharide(s) and/or protein(s) - to improve their sedimentation rate and filterability by adding specific enzymes to cause degradation
Inventor: CARLSSON CARL-GORAN HERBERT
IPC: C02F11/12
Filed: 1976-07-26
Abstract: The filterability and tendency to settle of slurries of fats, polysaccharides and/or proteins. is increased by adding to the slurry and enzyme which strongly degrades the macromolecular substance(s) present. The enzyme used depends on the effluent's content (e.g. lipases for fats, amylases and/or celluloses for polysaccharide and proteinases for proteins). The addn. of 0.001-5 wt.% pref. 0.1-1 wt.%, (based on dry wt.) gives marked improvement. Biological treatment is at 5-70 degrees C, pref. 20-60 degrees C.
