Title: Bicycle type rehabilitation appts. - has rotary adjusting screw with scale indicating braking roller load
IPC: A63B21/012
Filed: 1975-09-23
Abstract: The rehabilitation equipment is in the form of a bicycle, with a pedal mechanism driving in a wheel, against which a braking roller can be pressed with a variable force using a screw adjustment. The rotary adjusting screw (26) has a graduated scale from a zero position representing no resistance from the braking roller (13). The scale gives a direct reading of the effort to be exerted by the user on the pedals (7) to overcome the roller resistance. The scale can be a round dial fixed on the chassis (1) concentric to the hand adjusting wheel (26), which has a finger moving over the dial.
Patent FR-2286707-A1 (FR)
IPC: B31B1/90
Filed: 1975-10-02
Abstract: A plastic sachet is formed by applying a length of rip tape transversely across a length of plastic film and holding it under tension flat against the film whilst it is secured to the film by e.g. a heated welding bar. The tape is then cut by e.g. a cutter to leave a length of the tape projecting beyond the edge of the film, and the film folded over along a line perpendicular to the rip tape. The superimposed edges of the film are then heat sealed together and the film is cut to form the sachet.

Title: Audio amplifier with automatic level correction - has filter detecting LF signals that exceed set amplitude to reduce level
IPC: H04R3/00
Filed: 1975-11-19
Abstract: An automatic correction stage for sound reproduction systems allows high volume l.f. signals to be reduced using a power amplifier with variable feedback switching. The output of the amplifier is coupled to a low pass filter consistency of a resistance (RI) and capacitance (CI) with a lamp (L) connected in the loudspeaker circuit. The lamp is activated when an l.f. signal is generated that exceeds a predetermined level. A photo resistance (LDR) reacts to the light and reduces the signal level by up to 12dB.

Patent FR-2338549-A1 (FR)
Title: Spacing grid for nuclear reactor combustible assembly - has spring holders, and slots in grid increasing holder flexibility
Inventor: DELAFOSSE JACQUES
IPC: G21C3/356
Filed: 1976-01-14
Abstract: The grids are formed by perpendicular plates fitted together to form cells of square section. The plates have large hollowings sepd. by corrugated bands. The bands project into the cells and act as springs, holding rods of the combustible assembly against other such springs and against bosses in the flat parts of the sheets. Each rod is thus held in two different directions at four points regularly spaced around its periphery and at several points in its length. The cooling fluid circulates around the assembly through the openings, and the bands and bosses absorb vibrations. The invention improves the grid by increasing the flexibility of the springs so that they exert sufficient, but not too much, force in supporting the rods against the bosses and provide for variations in the dia. of the rods and the dimensions of the cells. This is achieved by creating a zone of reduced mechanical resistance in the plates, by making slots in the sheets where they join the bands, so that the plates can be distorted between the slots and the bands. This distortion is added to the bending of the bands. The curve of force exerted by the spring as a function of its bending is as flat as possible. Better equilibration of the support pressures, a greater range of operation, more uniform distribution of mass across the structure, less vibration and less wear of the rods are obtd.

Title: Heat treatment for zirconium base alloy - for structural components of a boiling water nuclear reactor
Inventor: WIL CEDRIC DAVID
IPC: C22F1/18
Filed: 1976-02-25
Abstract: The Zr-base alloy contg. Sn, Fe, Cr and an intermetallic phase as a fine dispersion has a microstructure in which the particles are dispersed in two dimensional order, pref. along the alpha grain boundaries and sub-grain boundary. The alloy has the compsn (approx) 1.5% Sn, 0.2% Fe, 0.1% Cr, 0.1% O, balance Zr and is free of Ni. Resistance against 'pustel' corrosion is improved by heating the body in stages to a temp. at which the alpha phase is at least partly transformed into the beta phase, maintaining the body at that temp. to effect transformation of the alpha-phase into the beta-phase, cooling the body during which the intermetallic phase is pptd. in the form of particles at the alpha grain boundaries. Used for nuclear fuel casings, conduits for receiving nuclear fuel bundles, and spacer grids.

Title: Hydrostatic extrusion cylinder press - has plunger and moulding die with seal rin on chamfered edges of cylinder
Inventor: LARSSON HANS-GUNNAR
IPC: B21C27/00
Filed: 1976-09-22
Abstract: The hydrostatic extrusion press has a receiver cylinder (3) containing a moulding die mounted on a support (7). There is a compression plunger (6) and sealing carrier ring on the end of rods (18).
