Patent FR-2381906-A1 (FR)
Title: Diesel engine running on water spray - has steam generated by injection of water into cylinders at end of compression stroke
IPC: F01K21/02
Filed: 1977-02-23
Abstract: Distilled water is injected as a fine spray into the cylinders of a diesel engine. The injection takes place at the end of the compression stroke and replaces the injection of petroleum or other fuel. The temp. reached by the air at the end of compression vapourises the water. The resulting steam expands and drives the engine doing useful work. The steam exhausted is condensed and the latent heat recovered is used to preheat the injected water. The condensate returns to the distilled water reservoir. Some of the condensate can be drawn off for use as hot water for domestic or other purposes. In this case fresh cold water is added to make up the volume in the engine circuit.

Title: Firearm aiming system for moving target - has cross-wires driven proportionately to telescope angular velocity with timer stopped after period proportional to range
Inventor: MOIREZ
IPC: F41G3/06
Filed: 1977-03-18
Abstract: The system aims a firearm at a moving target, having a telescope aligned with the firearm axis and slewing on a vertical axis, with cross-wires adjustable for alignment. A cross-wires drive moves them proportionately to the angular velocity of the telescope after measurement of the target distance by the range-finder. A timer controlled by the range-finder stops the drive after a period proportional to the range. This period starts with movement of the cross-wires by the drive. The drive can incorporate a clutch starting the cross-wires movement and also the timer, which in turn controls release of the clutch.
