Patent FR-2333944-A1 (FR)
Title: Solar energy powered engine - has reciprocating piston with grooves in stem acting as valve element in sleeve
IPC: F04B47/04
Filed: 1975-12-01
Abstract: The engine operates on a refrigerant vapour produced by a solar heater but can also run as a normal steam engine. It has a single acting piston (2) moved in one direction by the vapour and returned by a spring. Vapour from the solar heater is admitted through a normal sliding valve through which it is also discharged back to the heater. The valve is moved by vapour admitted to and released from it through passages in a sleeve projecting below the cylinder. Flow through these is regulated by grooves in a stem projecting below the piston and sliding with a tight fit in the sleeve.
Patent FR-2295770-A1 (FR)
Title: Contacting liqs. with vapours at high velocities - for mass transfer processes e.g. distillation, rectification, absorption
IPC: B01D3/20
Filed: 1975-12-19
Abstract: The contacting device consists of plates for dispersing the liq. into the vapour, having large open cross-sectional areas, and knitted wire mesh pads, for sepg. the liq. from the vapour, which are inclined to the dispersal plates. The dispersal plates and mesh pads are arranged one above the other and connected together by downcomer channels which are parallel to each other and extend over the whole cross-section of the device. The inclined mesh pads are openly connected through their lower edges to the downcomer inlets whilst the downcomers serving one level of pads pass downwards through the ridges in the next lowest level of pads and discharge the liq. onto a lower dispersal plate. High vapour velocities can be employed without excessive press. drops or liq. entrainment, enabling contact columns of smaller cross-sectional areas to be used.

Title: Target boring along inclined vertical axis - using elbow and guides above cutter and below stabiliser
Inventor: DICKY LEONIDE
IPC: E21B4/18
Filed: 1976-11-02
Abstract: Drilling towards a target from an initial vertical shaft along a curved axis is carried out by means of equipment including at the bottom of a train of boring bars, a subterranean motor, and a cutter head. A diversion of the line of boring in a given direction is brought about by means of an elbow joint placed between the subterranean motor and th boring bars. The guiding of the end of the train of boring bars is ensured, independently of the diversion >=1 guiding device. This has a form which brings it into contact with a limited zone of the periphery of the borehole, so as to allow a certain latitude in the direction of the diversion; the device being suitably aligned relatively to the elbow joint. Makes it possible to hold the elbow joint in the position necessary for drilling in the new direction desired. Both the inclination and the azimuth can be corrected easily.

Title: Carbon black pelletisation plant - having rotating mixer with pins on irregular helix protruding from hollow shaft
IPC: B01J2/10
Filed: 1977-07-08
Abstract: Pellets of carbon black are formed in a device with a hollow cylindrical shaft inside a cylindrical shell. Liquid is injected from holes in the shaft and mixing is achieved by pins protruding from it. These are uniformly spread over the surface of the shaft and extend to close proximity to the shell inner surface. The pins are located on an irregular helix which extends along the shaft. The spacing of adjacent pins is controlled by the equation P= (360 degrees/z). t where P is the posn. of individual pins, a is the azimuthal angular posn. between axially neighbouring pins and t is the axial spacing of neighbouring pins. all pins have a constant axial spacing (t) and only the azimuthal posn. is varied along the course of the shaft. The system gives good and rapid mixing after direct injection of pelletising fluid. It produces small uniform carbon pellets and the shaft has short stable, rigid pins.

Title: Leg muscle exercising boot preventing vein inflammation - generates alternating pressure on leg by pump between upper and lower soles
IPC: A43B13/20
Filed: 1977-09-09
Abstract: The boot designed to prevent phlebitis, exerts a permanent load on the leg and generates an alternating pressure to aid operation of the leg muscles. The pressure is generated by a pump between the upper and lower sole of the boot, and actuated as the weight of the body is shifted. The pump can have two chambers (1, 2), being actuated via springs (3) in the heel and toe. The air flows from one chamber through a port (4) into the other, in turn connected by further ports to a closed sleeve (5). There can be stiff bases (7) below heel and toe, so that air flows back and forth between the chambers as body weight is shifted.
