Title: Colour extn. from waste paper by macerating in aq. liq. - with simultaneous dispersion of gas bubbles in pulp
IPC: D21C5/02
Filed: 1975-08-11
Abstract: The extn. of hydrophobic colour (any type of printing ink) from waste paper comprises macerating the waste paper in an aq. liq. medium to form a pulp and dispersing gas bubbles in the pulp during maceration, so that the colour is conc. at the gas-liq. interface and floats to the surface of the aq. medium due to the buoyancy of the gas bubbles. The process is efficient and simple.

Patent FR-2307302-A1 (FR)
IPC: H01H15/16
Filed: 1976-04-08
Abstract: A switching mechanism for a timepiece comprising a base plate having first and second bores extending therethrough and intersecting, a circuit board having a surface opposite the second bore and having stationary contacts mounted on the surface opposite the second bore, and a contact member disposed within the second bore and dimensioned to slide therein. The contact member has a transverse bore extending therethrough and alignable with the first bore through the base plate, and the contact member has a conductive lower end portion extending from the base plate and terminating at a contact surface for contacting to electrically connect the stationary contacts on the circuit board. A spring biases the contact member downwardly to a lowered position with the contact surface contacting the stationary contacts on the surface board. A timepiece adjusting stem has an end portion dimensioned for insertion into the first bore and into the traverse bore for maintaining the contact member at a raised position with the contact surface thereof raised from the stationary contacts, and the adjusting stem is slideably mounted in a position aligned with the second bore for permitting the adjusting stem to travel in an axial direction thereof between a retracted position with the stem clear of the transverse bore of the contact member and an operative position with the stem inserted into the first bore of the base plate and into the transverse bore of the contact member to maintain the contact member in a raised position. The transverse bore has a tapered converging portion converging in an inward direction of the contact member so that the end portion of the stem bears against the tapered portion as the stem travels from the retracted to the operative position thereby causing the contact member to rise as the tapered portion of the transverse bore climbs the end portion of the stem traveling inwardly of the contact member until the stem extends into the transverse bore to maintain the contact member in a raised position.

Title: Tyre bead envelope presser for assembly drum - has self contained drive economising time and eliminating handwork
Inventor: GUBIN VALERY IVANOVICH
IPC: B29D30/32
Filed: 1976-07-06
Abstract: A tyre bead processing device for a tyre assembly drum includes an arrangement by which the layers for the bead reinforcement are turned over the bead ring. It is supported on the assembly drum shaft and has a drive for the energising of the various motions. The device includes a side cylinder built up from segments held together by an annular spring, and fixed securely to bars assembled in the hollow flange of a hub on the shaft. The hub can be moved axially along the drum shaft so as to extend the segment bars radially. The layers for enveloping the bead ring are turned over by bowed, roughly sickle-shaped levers, the butts of which are each attached at a pivot point on a radially extending bar; the free ends of the levers being secured to a pressing ring enclosing the circumferential segments. The bowed levers for turning over the bead layers and the levers for the radial motion of the segment bars are actuated through levers in slots in the segment bars, by two arrangements of rollers assembled on the hub of the device. Device is applicable to the prodn. of tyres for heavy agricultural machinery such as combines and tractors, etc. The tyres are of multi-layered cord fabric and manual operations are eliminated whilst high quality products are assured. The machine allows the prodn. of bead shoulders of =40 mm, and also it can turn over folds onto the face of the drum =150 mm long.

Patent FR-2332148-A1 (FR)
Title: Pneumatic tyre mounted on a very much narrower wheel - withstands partial or complete under-inflation
IPC: B60B25/02
Filed: 1976-11-18
Abstract: Pneumatic tyre is mounded on a very narrow wheel. The thickness of the tyre rims is at least a third of the width of the wheel. Typically a 155 mm tyre is mounted on a 37 mm wheel rim (ration >4:1). If a tyre of the usual type loses all or most of its inflation pressure, the rims of the tyre are liable to come away from the wheel rims, leaving the tyre uncontrollable. The invention overcomes this by mounting the tyre on so narrow a wheel that there is no room for its rims to come away in this fasion. Also a flat tyre does not run so hot on a 37 mm wheel as on the normal 80 mm.
