Patent FR-2332641-A1 (FR)
Title: Windingless permanent magnet motor - has circumferentially displaced stators with varying airgap and uses build up of energy in magnets
IPC: H02K53/00
Filed: 1975-11-19
Abstract: A windingless motor is dependent on the build up of magnetic energy in permanent magnets. The driving energy may be derived from solar or electrolytic sources. The displacement of the fields required to cause armature rotation is achieved without the use of auxiliary mechanical arrangements. Attraction and repulsion is set up by pole piece heads, field displacement being due to a fixed permanent magnet providing polarisatin of the pole pieces as they pass them. This is achieved by providing an iar gap which opens out from a narrow section to two diametrically opposed gaps increasing symmetrically in size towards the stator pole centres, the stators themselves being displaced circumferentially.

Title: Press bonded timber frame table mat - has tiles set proud in opposed major faces and uses mitred rebate grooved frame
IPC: A47G23/06
Filed: 1975-12-15
Abstract: The tiles (14, 17) are mounted in a square or rectangular mitre joined frame (16) with a plywood sheet (P) in the median major plane. The edges of the sheet are housed in frame member (16) grooves (7), and the tiles are set proud in the resultant opposed major face recesses. The grooves (7) are of a 'T' section to permit the deployment of high pressure with fragile tiles. Initially the tiles may be measured in a template frame, frame members made to suit the smaller tile (14) and the frame assembled with shim sheets (36, 38) and the plywood insert (P). The recess for the larger tile is then scribed (59) and cut and finally the mat assembled in a single pressure bonding operation.

Title: Tongues for railway points - are bolted together before being butt welded to end of tongue (NL280976)
Inventor: WEBER LOTHAR
IPC: E01B7/12
Filed: 1976-01-16
Abstract: The tongue tip has a front block driven over and to which connecting rails are butt welded. The two connecting rails are clamped together for butt welding to the front block on the tongue tip. The clamping is achieved by high-tensile prestressed bolts, or the two connecting rails may be located loosely side by side during butt welding. Only the front block (4) need consist of a drop forging. Prior to butt welding the connecting rails (5, 6) to the block (4), The rails are clamped together by high-tensile prestressed bolts (7, 8), using a filling plate (9) coated with adhesive which fills any residual gaps and ensures the location of rails when they are simultaneously butt welded to the front (4) of the tongue (3).

Title: High speed nut cutting machine blank feed - has plate on oscillating and reciprocating shaft providing stepping movement
IPC: B21K27/04
Filed: 1976-01-23
Abstract: The nut blanks (60) are guided between the edges of flat plates (40) forming a passage (41) along their length. Perpendicular to and opposite each blank are the die sets. Movement between dies is by a plate (21) operating in front of the row of blanks. This plate has recesses (212) along its top edge (211) which provide nests for the blanks. The plate is fixed (20) to levers fitted to a shaft which has an oscillating motion alternately bringing the plate into contact with the blanks and moving it away. It also has a linear reciprocating travel. The combined movement moves the blanks progressively between the stations.

Title: Automatic camera with exposure mode selection - has common setting control for preset speed or aperture
Inventor: SAKURADA NOBUAKI
IPC: G03B7/091
Filed: 1976-02-27
Abstract: The camera is fitted with a single setting control to select either a preset exposure time or aperture. The control comprises a cam plate inside the reqind lever pivot on the top of the camera, with cam provided with sets of resistance tracks monitored by the exposure circuit of the camera. A visible scale reminds the user which mode has been set while the exposure circuit automatically corrects the exposure. A simple electronic logic, with a changeover switch, automatically operated, is used to control the mode of the camera, while flm speed etc. are fed into the circuit by common controls. The single setting control is designed to be fitted to cameras with only one mode, to convert them to the two mode variety.

Title: Gas burner with cover sheet having gas outlets - has lateral and longitudinal boundary edges with cover having radius of curvature less than that of lateral engaging edges (BE270976)
IPC: F23D14/10
Filed: 1976-03-24
Abstract: A gas burner, the body of which has a cover sheet with gas outlet apertures, mounted over the gas outlet by elastic slide mountings such that the gas outlet is bounded of longitudinal and lateral edges, has the burner body (1) in the form of a circular cylinder sector at least in the region of the gas outlet (2). The projecting longitudinal edges (3, 4) lie on the jacket of the cylinder, whilst the lateral edges (5, 6) running between them, have a primary radius of curvature (R1). The cover sheet (7) has bent edges (8, 9) to engage the longitudinal edges (3, 4) and has a radius of curvature (R2) which is smaller than that (R1) of the lateral edges (51), causing the draught forces to be limited by the lateral (5) and longitudinal (3, 4) edges.

Title: Prestressed cable pulling process - uses offset pressure rollers causing cable to undulate between when tilted by adjusting screw (DK 12.12.77)
IPC: B65H51/10
Filed: 1976-04-13
Abstract: The process is for unrolling a long flexible item with the aid of pressure rollers, being particularly for pulling or thrusting a prestressing cable. The rollers (1, 2) are offset in relation to each other, and their distance from the axis of advance of the cable etc. (3) is adjusted so as to cause an undulation of it between them. The amplitude of the undulation determines the amount of grip, by varying the area of the contact surfaces between the cable and the roller grooves. The rollers can be mounted in pairs coupled by parallel and pivoting links, their angle regulating their position in relation to the cable.
