Title: Over cast stitch sewing machine - has table with needle aperture allowing initial stitches to be stitched into fabric to prevent unlocking
IPC: D05B1/20
Filed: 1975-02-24
Abstract: A sewing machine for producing over-casting stitching has a table over which a textile work-piece passes beneath a stitching needle, and the table has an aperture into which the needle passes after the needle has penetrated the work-piece.

Title: Continuous charcoal production - using inclined rotating retort into which air is directed for burning wood gas to carbonize wood
IPC: C10B53/02
Filed: 1975-04-14
Abstract: Charcoal is produced from wood by continuously introducing wood chips into the higher end of a slightly inclined retort, rotating about its longitudinal axis so that the chips form a bed only partially filling the retort and are constantly tumbled and advanced to the lower end of the retort, heating the chips using an external fuel long enough to initiate the production of combustible wood gas, and introducing air tangentially into a peripheral portion of the retort not occupied by the bed, in a direction opposite to that of rotation of the retort, so that the wood gas is entrained in the circulation, mixed with air, and burned to the extent of the available oxygen before the circulating gases reach the bed, where they carbonize the wood chips to produce charcoal which is removed from the lower end of the retort. High grade charcoal can be produced in a continuous process, with little prodn. of smoke or objectionable fumes; after initiation the process is self-sustaining without using external fuel; large quantities of useful heat are produced.
Patent FR-2307914-A1 (FR)
Title: Construction of continuous welded rail track - involves string of two-storey flat wagons carrying overhead gantry crane which avoids construction of temporary track
IPC: E01B29/02
Filed: 1975-04-18
Abstract: Railway construction involves laying sleepers and continuous welded rails onto a new track without the need for first laying an auxiliary track. All of the elements needed for construction are first loaded onto a string of flat wagons with two floors, the lower one being used for the rails arranged lengthwise side-by-side, and the upper one being removable and used for the sleepers which are arranged transversely. Each truck has along the lengthwise edges of the upper floor a rail on which a gantry crane can slide. At the front of the string of wagons is a similar wagon whose upper floor remains empty. Once in position, sleepers are placed on this floor by the gantry crane and are then placed on the track by a second crane. When sufficient sleepers have been laid, two rails are then withdrawn and put in place.

Title: Toothbrush with forked brush end for better cleaning - has bristles set V-shaped forming prism cavity for easier access to back teeth
IPC: A46B9/04
Filed: 1975-10-09
Abstract: The toothbrush comprises a handle which is angled at the front ent where two bristle arms (2, 3) are mounted opposite each other in V-shape so that the bristles (7) attached to the arms produce a prismatic gap (5). This brush allows an effective cleaning of all the teeth, even those at the back and in addition a cleaning of the gums. The brush can be readily manufactured by bifurcating the end of the brush handl and attaching the bristle tufts parallel to each other in the forked ends. Through thermoplastic processing the handle ends can then be turned towards each other so that the tufts are set at the right angle.
