Patent FR-2288045-A1 (FR)
Title: Return device for high speed chain conveyor - has flexible guide on pushers movable by cable engaging pusher rollers and fixed rollers
IPC: B61B12/10
Filed: 1974-10-17
Abstract: The incoming and outgoing lengths (1, 2) of conveyor pass round a conical section casing (3) of flexible material. The rigidity of the casing is controlled by two cables (6, 6a) with tensioning springs (9). The cables pass over pulleys (7), or the ends of pushers (4) connected to the casing, these pushers alternating with fixed pushers (5) which also engage the cables. Means are provided for measuring and correcting differences in tension between the two cables. A vibrating device (12) prevents the conveyor from binding against the surface of the casing.
Patent FR-2289359-A1 (FR)
Title: Twin axle for terrain vehicle - with wheels on each axle joined by crank levers and elastic links
IPC: B60G5/01
Filed: 1974-10-29
Abstract: The twin axle unit has the wheels joined to half shafts (5) which are fitted with crank levers near the middle of the vehicle. The ends of the crank levers are joined by a common axle (7) which is linked to the main support axle (4) of the twin axle unit by elastic springs. These tend to hold the cranks in a horizontal setting towards the main axle, with both wheels on each axle at the same height. Displacement of the wheels in a vertical manner is possible with individual crank movement against spring pressure. This provides a simple independent suspension for the terrain vehicle with a compact layout.

Title: Portable indoor bowling game - ball moves along a groove in which the pivotal pins are erected
IPC: A63D1/00
Filed: 1975-01-08
Abstract: The groove is formed of two parallel rails (14 & 15) and the pins (18) are erected in this groove on the trajectory of the ball. At the end of the groove there is a ring (22) to collect the ball and to return it to the start (12). The groove is mounted on supports so that the height of the groove can be modified progressively. The groove is inclined so that the ball travels up the groove towards the pins and the object of the game is to knock over as many pins as possible. The pins are pivotally mounted and limited in their return movement by adjacent stops. The guide rails are typically seamless tubes.

Title: Disc brake with pivotal actuator - has ball joints on two fasteners securing actuator
Inventor: COURBOT PIERRE
IPC: F16D55/2255
Filed: 1975-01-15
Abstract: A motor vehicle disc brake has an hydraulic actuating cylinder (12) operating directly on one brake pad (30) and connected to a frame which operates on the pad on the other side of the disc (28). The cylinder is mounted pivotally by ball and socket fixings each having a spherical head (34) on a shaft (26) which is part of a screw (38, 44) or, in a variant, an integral head and shaft, retained by a nut. The parts may be assembled even if there is some mismatch, for example the ball shaft or screw may be angled slightly to engage the first few threads. Subsequently tightening the nut of screw draws the parts into reasonable alignment with the ball and socket axes parallel to that of the disc. Final rigidity is ensured by interposing a collar (46) between the ball head and the stub axle (42). Seals and covers (58) are fitted to exclude grit and moisture.

Title: Sheet material marking for templates - using graduated raster on sheet applied directly or through plastic layer
IPC: G01B3/14
Filed: 1975-06-13
Abstract: A means of avoiding or reducing the disadvantages of conventional sheet material marking methods is used for sheets intended as templates or actual material to be processed. On at least one surface the sheet has a raster in the form of a rectangular grid. The elements of a raster are squares with sides of one millimetre or an exact multiple of one millimetre, of it maybe graduated in fractions of an inch. At least one line of the raster may have numerical indication relative to a reference point. Various types of marking may be used, including coloured, for which an aluminium sheet is suitable. The method facilitates marking, centre-punching or tracing accurately yet quickly and conveniently.

Title: Briquetting loose materials using explosive energy - in a device having actuating cylinders for briquette removal
Inventor: KONONENKO V G
IPC: B30B1/00
Filed: 1975-06-17
Abstract: A briquetting device which utilizes the impulse energy of detonation includes an explosion chamber provided within a housing having a piston and a finder assembly. The housing is movably mounted on a bed plate adjacent an anvil with a container arranged intermediate of the housing and anvil. A die is positioned intermediate of the anvil and container and integral with the latter. Rods provided within the anvil are connected rigidly to the die to move the die towards the housing after briquetting and so cause pushing out of the briquette by a plunger attached to the piston rod in the housing. Used for briquetting of steel turnings, titanium-base alloy turnings, concentrates and refractories. Briquetting can be performed in a vacuum or inert atmosphere. The device has an increased output since it enables auxiliary operations associated with setting of the device to be carried out simultaneously. The die design permits the briquetting of fine, disperse loose materials.

Title: Antihypertensive, antiulcer prostaglandins
Inventor: EGGLER JAMES FREDERICK
IPC: C07C405/00
Filed: 1976-10-21
Abstract: Optically active tetranorprostaglandins (I) (and optical antipodes, racemates, and non-toxic salts) are new: (where X and M are keto, Q = tetrazol-5-yl; Ar = Ph (opt. substd. by F, Cl, Br, CF3, Ph, or lower alkyl or alkoxy), or alpha- or beta-naphthyl). (I) are much more stable than prostaglandins (e.g. PGE2), and posses highly selective activity profiles, and are longer acting than most naturally occurring PG's. Thus (I) have antiulcer properties (in rats at oral doses of 1 mg), and antihypertensive activity, but other PGE2-type physiological properties are depressed

Title: Liquid filled channels for trapping solar energy - where channels are mounted side by side to form hemispherical array
IPC: F24S23/00
Filed: 1977-03-09
Abstract: Pyramid section channels filled with liquid are used to trap solar radiation on the large face and focus it on the smaller face of the section. Channels are mounted side by side to form a hemispherical array aligned to absorb radiation successively during different periods of the day. The channel walls are of glass, the liquid water or an alcohol. The included angle of the channels is 30 degrees-40 degrees, so that fire may be assembled to provide 180 degrees coverage. The liquid is a simpler, cheaper absorbant than complex multilayer traps.

Title: Die cutters for isolating integral mouldings from rubber sheet - involving spacer to maintain the cutting zone in tension
IPC: B29C67/00
Filed: 1977-06-21
Abstract: The back pressure plate for a die tool for severing individual moulding from an integral support sheet of elastic material (solid rubber) is fitted with a face plate drilled to support the sheet clear of the panel profile and thus ensure that the material in the zone to be cut is in tension during cutting. The boder of the cut zone is more constant than that from processes where the rubber is locally in compression during the cutting stroke and results in an enlarged profile due to elastic recovery after release.
