Patent FR-2263269-A1 (FR)
IPC: C08C19/00
Filed: 1975-03-06
Abstract: Polymers are rendered more oxidatively stable by reaction with an antioxidant or stabilizer, generally a vinyl-group- or thiol group-containing antioxidant, in the presence of a free radical which may be produced by a redox system or ultra-violet light. The resulting polymers can be used as such or can be used as additives in other polymers to stabilize the latter.

Title: Glass batch prepn. using alkali(ne earth) oxide precursors - mixed with water using predetermined hydroxyl/other ion ratios
IPC: C03C3/00
Filed: 1975-03-11
Abstract: In the prepn. of starting materials for glass mfr. contg. sources of alkali(ne earth) oxides as hydroxides and carbonates, the alkali carbonate/alkaline earth hydroxide/water/alkali hydroxide/alkaline earth carbonate system is lead by determined reaction of its components and with other ingredients to form a mixt. in a stage of high reactivity, favouring and accelerating fusion. The starting materials are mixed in proportions such that the molar ratio between all the hydroxylions and all the carbonate ions is 4:1-1:1 (2:1), the molar ratio between the water present or added and the hydroxyl ions is 4:1-1:2, and the progress of the desired reactions is influenced by controlled conditions of temp. and pressure. Control of the hydroxyl ion ratios with other components gives closer control of the prod. compsn.

Title: Combined evaporator, expander and heat exchanger - has helical inner chamber and outer heating chamber between concentric tubes
Inventor: CACHARD MAURICE DE
IPC: F25B39/02
Filed: 1975-09-11
Abstract: The refrigeration device or heat pump uses a combined evaporator, expansion chamber and heat exchanger. It has an inner tube (20) with a helical rib (30) around its outside, fed from above with a fluid to be evaporated, such as freon, under pressure. Another tube (34) with fins (36) around its outside forms a helical chamber (38) which communicates with the interior through a set of narrow channels (32). An outer tube (44) forms encloses a space (46) to form a chamber for the fluid to be cooled. The freon passes through the channels (32) and impinges on the inside of the finned tube (34), forming a film (52) on the surface and vaporises, leaving through a top outlet (42). This gives very good heat exchange conditions with the fluid, such as water in the outer chamber (46).

Title: Paper bale binding electrical cutter - melts metal binding locally between double contacting rollers and has sprinklers to protect bales
Inventor: WAENERLUND LARS
IPC: B65B69/00
Filed: 1975-12-23
Abstract: Paper pulp bale binding is fusion released electrically, across pairs of electrodes. Conveyed banded bales traverse a turntable. Current across articulated twin-disc contacts melts the metal binding, obviating manhandling and hand tool cutting of recalcitrant tight binding. Water sprinkling prevents pulp burning and discolouration. A turntable (3) between the conveyors (14,15) receives a tied (6) bale (2). Sideways swinging arms (7,9) carry electrified roller discs (10), pressing on one or both sides of the spike (17) held bale, at two different heights for assured severance. Feed, holding, table rotation and the pressure exerted by the electrodes are automatically controlled.

Title: Soil cultivation process - uses turning over and pulverising involving passage through helical duct defined by rollers or endless belts
IPC: A01B79/00
Filed: 1976-04-23
Abstract: A process for putting land into a cultivatable condition involves the guiding of soil into a helical duct to effect the turning over of its contents, and subsequently the treatment by pulverisers. The helical path may be defined by rollers controlled by bars, or the rollers support endless flexible belts. The pulveriser leaves impurities previously on the surface at the bottom of a furrow so that they are not mixed with the soil being moved. The remainder of the soil is finely worked by the pulveriser (8) so that the furrow is filled. The soil is brought into cultivatable condition in a single pass of the machine.

Title: Hand-loom with modified healds and reeds - to simplify threading up and improve warp tension
IPC: D03D29/00
Filed: 1977-02-03
Abstract: The threading up of warps in hand looms for weaving is simplified by using healds with open heald eyes and open hooks, and reeds with removable dents. The healds may be threaded up by unhooking the heald from the frame and feeding the warp yarn through the sides of the heald eye. The reed frame constitutes two slides connected to uprights to form a frame into which the dents are slotted. The lower slide has a U-shaped profile, with one side divergent from the vertical to allow the disengagement of the dents for the insertion of the warp yarns. The upper slide has a movable part to allow for the lifting of the dents from above, and to provide a vertical block when the dents are mounted into the frame. The time spent threading up the loom is reduced by 60-75% by simplifying threading up and omitting the knotting procedure. The omission of knots improves warp tension.
