Title: Spherical space frame for building - comprises five circles with diameters intersecting points of decagon
Inventor: SAUNIER SERGE
IPC: E04B1/32
Filed: 1981-06-18
Abstract: The spherical or semi-spherical framework for use as a shelter or exhibition, is made out of five identical circles, the dia. of which pass through the points of a decagon on the circumference of an imaginary horizontal circle (C). The planes of the five circles form an angle of 63 deg.26' or 70 deg.48' with one another and with the plane of the horizontal circle. The resulting framework is formed of twelve regular pentagons and of twenty equilateral triangles, the sides of which are the same length as those of the pentagons.

Title: Machine feeding trays to and from machine tool - uses linearly reciprocating slides coupled selectively with trays traversing parallel rails
Inventor: MUNEKATA KENICHI
IPC: B23Q7/14
Filed: 1981-08-07
Abstract: The machine feeds workpieces to and from a machine-tool with a machining table (10), handling trays (P) upon which workpieces are mounted. It uses two pairs of parallel horizontal rails (16) mounted on a substructure (13) by the table (10), the rails locating an input tray and an output tray respectively. The substructure (13) also supports and provides guidance (22) for two slides (24) which move parallel to the rails and can engage the respective trays (P). Also mounted on the substructure is a central motor which drives two transfer arms (56) through oscillating radius arms (52) controlled by selectively actuated clutches. A transfer arm (56) drives each slide (24) and may actuate slide-to-tray couplings (26).

Title: Insulated tipping container for lorry - incorporates reinforcement to prevent deformation to stop formation of thermal bridge
IPC: B60P1/16
Filed: 1981-08-06
Abstract: The tipping insulating container for lorries or trailers comprises a hydraulic ram which pivots the container, allowing the contents to unload under gravity. The container incorporates a reinforcement panel (12) on the front face of the container, which prevents deformation as the ram is actuated and yet does not form a thermal bridge between the interior and exterior of the container. Longitudinal beams (17,18) reinforce either side of the floor (26) and extend from the front face (8), up to the pivotal axis of the container.

Title: Floating mount for seat belt retractor - has toothed track engaged by locking pawl on retractor mount which tilts into engagement if sudden force is experienced
Inventor: PILARSKI REGIS VICTOR
IPC: B60R22/26
Filed: 1981-09-22
Abstract: The seat belt retractor is provided with a mounting which moves with the seat when the seat is shifted forwardly or rearwardly. The retractor (19) is attached to the seat frame by a resilient coupling (16) and is mounted on a sleeve (15) movable on a track (17). As the seat is moved, the retractor and sleeve move and relocate on the track in accord with fore and aft movement and vertical displacement. Ratchet teeth (27) are provided on the track and a spring (35) biases the retractor from lock engagement against the teeth. Under upward stress by the seat belt, the retractor tilts and a pawl (34) on sleeve (15) engages the ratchet teeth and secures the retractor against any further movement.

Title: Non-contact radiation thickness gauge system - employing accurate quadratic interpolation method for calibration
Inventor: TSUJII TATSUO
IPC: G01B15/02
Filed: 1982-02-22
Abstract: Non-contact radiation thickness gauge system, which uses several movable standards of predetermined thickness values, comprises (i) a radiation source, (ii) a radiation detector producing output signals functionally related to the level of radiation received, and (iii) a memory for storing calibration curve-defining parameters for calibration curves corresp. to respective thickness ranges. The calibration points for the curves selected approximate geometric series of thickness values over the entire range and at least three calibration points and the corresp. detector output signals define each curve. A unit is provided for setting a nominal thickness and alloy compensation coefft. for the material to be measured. The output signals from the detector and the setting unit, when the material to be measured is in the radiation path, are processed with a calibration curve stored in the memory to determine the thickness of the material. The system can be used for on-line measurement in rolling mills where rapid automatic adjustment is necessary to achieve continuous and uniform metal strip thickness. The system relies on a highly accurate quadratic interpolation method and allows adjustment for alloy compensation during the measurement mode rather than during calibration.
Patent FR-2523550-A1 (FR)
Title: Push on twist off bottle top - latches onto neck as pins on elastic walls enter grooves in cammed profile
Inventor: LEQUELLEC JACQUES
IPC: B65D41/17
Filed: 1982-03-16
Abstract: The bottle (1) top (2) is of the push-on twist-off type, housing onto the neck of the bottle to take a grip by pins (6) on the inside of a resilient wall engaging behind neck shoulders (5). A radially cammed neck profile ensures that the pins clear the shoulders when the top is rotated whilst a taper (3) provides an axial force easing the top off the neck once released. The neck may be surmounted by a ring (3) with a non-circular external profile and tapering to a reduced width at the top.S The shoulders may be formed by horizontal 'V' section grooves sited in the neck zones with the greater radii, the effective groove depth reducing progressively from mid length to each end. The top may also have an inner wall of which the foot catches the bottom of the ring, these connections also being made in the zones with the greater radii.
Patent FR-2525403-A1 (FR)
Title: Automatic conveyor mechanism for cutting and stripping wire sections - uses system of toothed belts to increase accuracy of wire length drawn and has articulated jaw mechanism to strip insulation
Inventor: LOUSTAU DESIRE
IPC: H01R43/052
Filed: 1982-04-16
Abstract: The mechanism is part of a fully automatic and programmable sequence and runs on a conveyor carousel arrangement. Wire is drawn from a supply reel and passes between a set of toothed belts. A large belt is driven around pulley wheels by a smaller, internal belt whose teeth mesh with those on the inner surface of the first belt. The wire is pressed against the first belt by another belt which moves in the same plane. Loosely mounted rollers form a flexible support for the wire. The wire-stripping work station has an articulated pair of jaws armed with blades which pierce the insulation from opposite sides of the wire. The jaws are driven by a worm gear via an eccentrically mounted pin and disc. The jaw assembly is moved longitudinally along a slide bar by a stepping motor. The separation of the jaws and length of insulation removed from the wire can be varied.

Title: Forming expandable bellows filter - by forming cylindrical tube filter, sealing inside, expanding to deform tube and removing seal
Inventor: BURNEL PHILIPPE
IPC: F16L27/11
Filed: 1982-05-18
Abstract: Method of mfg. an expandable bellows filter comprises (a) selecting a cylindrical filter tube; (b) placing inside the tube an expansible sealed element; (c) submitting the sealed element to internal pressure to expand and deform the tube; (d) forming on the tube, waves perpendicular to the tube axis by deformation against a series of moulds applied during the course of expansion of the sealed element, and closing the moulds together along the length of the tube; (e) removing the pressure and (f) the sealed element. The filter is esp. for filtering high pressure steam at high temp. The method overcomes the prior art problems of forming a wave form on the side of a tube and producing a deformation of a fine metal foil which is highly stretched into a wave form.
