Patent FR-2261175-A1 (FR)
Title: Water jet propulsion unit for inflatable craft - casing secured by bolts to rear of hull, sleeves slide over buoyancy tubes
IPC: B63H21/14
Filed: 1974-02-15
Abstract: A propulsion unit for inflatable craft has a housing which locates between the two longitudinal inflatable cylinders forming the sides of the craft, shaped to match the contour of the hull. For additional support, the housing has an integral hollow sleeve each side to slide over the rear parts of the inflatable cylinders which extend beyond the hull. This housing contains a motor driving an impeller which produces a water jet to propel the craft. Water enters a port on the underside and is forced through a tube to be expelled rearwards. The housing includes a battery compartment and a fuel compartment, and a large proportion of empty space inside is foam filled for added buoyancy. The underside carries longitudinal ribs forming a keel.

Title: Asphaltic road making compsn. - including refuse incinerator residues as aggregate
IPC: C08L95/00
Filed: 1975-04-03
Abstract: An asphaltic paving compsn. consists of (by wt.) 5-95% of unfused and unclinkered continuous feed municipal incinerator residue, 0-33/4% lime, 0-90% of mineral aggregate having a max. ave. dia. of 1 1/2 inches, and 5-11% (based on the wt. of the other components) of asphalt. The residue has is not >15% loss on ignition, particle size not is not >2 in., and a ferrous content is not >5%. The compsn. may be made by removing oversize particles and ferrous material from residue to satisfy the above conditions and then blending it with asphalt and other premitted components. The cost of the compsn. is significantly reduced by replacing stone with the residue, while as little as 5 1/2% of asphalt is satisfactory with the latter, whereas 10-12% is necessary with blast furnace slag. The problem of residue disposal is mitigated.

Title: Epicyclic or hypocyclic gear train construction - has toothed belts carried on input and output drums connected by pinions on eccentric
IPC: F16H9/26
Filed: 1975-07-01
Abstract: The epicyclic or hypocyclic reduction gear train is constructed with toothed belts. The body carries a drum inside the periphery of which is fixed a toothed belt. A concentric output shaft carries a similar drum which carries another toothed belt. The drums are adjacent and face each other so that an eccentric shaft carrying freely turning interconnected pinions and driven by the high speed input shaft can connect the two. A counter weight balances the eccentric shaft. In the case of hypocylic gears, it is possible to make the number of teeth on the pinions one less than on the ring gears. This feature enables almost all the teeth to be in mesh and thus increase the torque transmission capability.

Title: Fuel injection plunger pump - has small annular area through which clamping force is exerted on plunger cylinder
IPC: F02M59/02
Filed: 1976-07-13
Abstract: The fuel injection pump has a plunger working in a cylinder in the pump body, with steps in the latter and on the cylinder held against each other.

Title: Magnetic head for fine matrix paper printing - uses tint transfer and has different conductivity sheets varying current proximity
IPC: G03G19/00
Filed: 1977-04-14
Abstract: The magnetic recording device is for printing characters on paper and has a magnetic tape moving past a recording head and a tinting unit which places tinting agent on the magnetised parts of the tape for transfer onto the paper. It is designed for fine matrix printing of small characters where matrix elements must be close together without the usual expense of producing the recording head. The head contains a group of recording zones placed across the tape path containing a thin conducting nickel sheet nearest the tape. A thicker copper sheet on the remote side of the nickel sheet has narrow gaps at the recording zones. Current flowing in the copper sheet is too far from the tape to magnetise it, but at the recording zone cut-outs the current flows close enough to magnetise a correspondingly small part of the tape.
