Title: Soft ground excavation and construction technique - using hollow rod with retractable blades at bottom
IPC: E02D5/80
Filed: 1975-01-06
Abstract: A cylindrical area of soil is broken up by means of one or more radial blades attached to the bottom of a hollow rod which is rotated, driving the rod to the required depth. Once this is reached, the rod and blades are withdrawn. Whilst the rod is rotating during insertion and/or withdrawal, a grouting agent can be poured down it which passes through a fish tail extension of the rod into the excavated area below the blades. Material to be used in the construction process can be inserted into the cylinder through a smaller tube without the necessity for removing the soil. It is also possible for the rod and blades to be cast into the concrete to form an anchor-brace.

Title: Piston lubrication for pneumatic cylinders - has symmetrical lubrication thrust pads with piston channels
Inventor: SCLINGAND MICHEL
IPC: F15B15/14
Filed: 1975-04-14
Abstract: The lubrication is by cooling, and is for a piston, displaced pneumatically within a cylinder, of reinforced synthetic material. A small pad is formed from the drive medium between the cylinder wall and the piston surface. The pneumatic medium is symmetrically applied on both sides of a sealing element (g), positioned in the central transverse plane of the piston. An independent lubricating pad of the medium is created on either side of the seal, one pad being formed by the thrust of the medium, the other by the counter action, which is applied to the medium during damping of the piston movement at the end of its stroke. Piston and cylinder are connected by a fluid channel system. The piston has two steps (h, h1), one or either side of the seal. The piston steps create independent medium circuits for the formation of the pads.

Title: Fourier transform spectroscope system - uses Michelson interferometer and has mirror on transducer for simultaneous interference pattern recording
Inventor: CHALIER CLAUDE
IPC: G01J3/453
Filed: 1975-07-31
Abstract: Problems of non reproducibility of spectra due to poor stability of a luminous source in an interferometer for Fourier transform spectrometry are overcome to enable simultaneous recording of interferograms of the source only and the source plus sample being investigated. A large area spherical convex mirror (Cc) is mounted in an interferometer and a small spherical concave mirror (Cv) is mounted on a piezo electric element to enable it to be displaced. Construction of the piezo electric element ensures that displacement is proportional to applied voltage with a high degree of precission to give required reproducibility. The sample under investigation is moved into and out of the path of the luminous beam in a time equal to the movement time of the large mirror to produce interference patterns.

Title: Collector and extinguisher for combustible liqs. - esp. sodium in reactor circuits, has vessel cover with retractable shutters
Inventor: COLOME JACQUES
IPC: G21C9/04
Filed: 1975-07-31
Abstract: An arrangement for extinguishing a combustible liq. by insolating it from the atmos., comprises a vessel below for collecting the liquid and a cover above closing it. In the cover a number of drainage channels with inclined sides facilitate the flow of the combustible liq. through openings at the bottom of the channels, which are closed by retractable shutters, yielding under the pressure of the liq. in the drainage channels, and closing automatically when the liq. has flowed in. The cover of the vessel is formed by a number of plates folded slightly, rooflike with the ridge on top, positioned on two levels, adjacent plates being offset vertically to each other, so that their outer edges delimit the openings of the drainage channels. The under face of each upper level cover plate, has along its edges a strip of metal folded and welded with a flange pointing upwards on which a shutter pivots on its corresp. flanged edge. Partic. applicable in connection with the liq. sodium circuits of a rapid neutron reactor, its heat exchanger and the steam raising plant, to prevent the combustion of a sheet of sodium arising from the leak, and the pressures and poisonous vapours arising therefrom. The shape of the vessels can be adapted precisely to the piping installation and separate vessels can be interconnected by means of inverted "U" pipes to recover the whole of any leakage.

Title: Electrically assisted pedal cycle - has magnets along wheel rim working with stator to recharge battery and act as regenerative brake
Inventor: GAFFNEY EDWARD NORMAN
IPC: B62M6/40
Filed: 1976-10-29
Abstract: The electrically-assisted pedal cycle has an electric motor with battery and generator. The latter is constituted by a series of magnets (21) along the rim of one of the wheels (12) and a stator (22, 23) mounted near the rim, whose winding can be connected to the battery via a hand-operated normally open switch and a rectifier.
