Title: Clip for laundry items etc. of plastic - has two hinged, spring-loaded arms locked by pivoting latch
Inventor: NODA TAIZO
IPC: A41F3/02
Filed: 1978-04-26
Abstract: An upper arm, a lower arm and a latch, all moulded in synthetic resin, together with a steel coil spring, form a clip for hanging linen, etc. The upper arm has bearings and supporting details which include a plate extending backwards from the flanges of the moulding. The inner ends of the latch slide across the iner surface of the plate behind the bearing points, whilst the outer end forms a lever and has a slot into which a strap for handing can be inserted. The lower arm has two journals which are sprung into the bearing bores in the flanges of the upper arm, so that the two arms pivot together. Behind the pivoting point in the lower arm there is a semicircular recess for the shaft on which the latch turns in contact with the inner surface of the upper arm, to lock the serrations at the front end of the clip against the pressure of the opening spring. Clip can be mfd. easily and economically. Damage to it during assembly and use is slight. The clamping force, on thick articles, is maintained until the latch is moved intentionally. The clip is small and neat in appearance.

Title: False-twisting device - offers alternate twist to yarn by means of rotary discs with separate frictional areas on their periphery
Inventor: VENOT JEAN
IPC: D02G1/08
Filed: 1978-06-06
Abstract: Alternate twist is conferred on continuously moving yarns using rotary discs mounted on two spindles, and driven in opposite directions to each other, with the shafts of the spindles parallel and the two disc at least partially overlapping. The surfaces of the discs comprise frictional elements on their surfaces, separated by non-frictional surfaces. The yarn (A-B) is led between the two discs into the contact zone of the frictional elements and is pinched between them during the rotation of the discs. Alternate zones of S and Z twist are conferred on the yarns by the rotary discs of the invention, and such treated yarns may then be placed side-by-side to form a self-twisted yarn by de-phasing the twist conferred upon the components.

Title: Chassis de vehicule muni de traverse de torsion
IPC: B62D49/00
Filed: 1978-09-08
Abstract: L'invention concerne un châssis de véhicule muni de traverses de torsion. Le châssis 44 comporte deux longerons 62 reliés entre eux par une traverse avant 70 et par une traverse arrière de torsion 72 dont des éléments sont orientés approximativement parallèlement et d'autres perpendiculairement à la longueur des longerons de façon à donner aux châssis une rigidité pluri-dimensionnelle. La traverse 72 coopère avec les longerons pour former un carter étanche à l'huile servant à loger l'ensemble d'essieu arrière du véhicule. Du fait que la traverse de torsion combine les fonctions de deux des organes des châssis Connus, le châssis est plus léger et a un centre de gravité plus bas que les châssis de la technique antérieure. Application aux tracteurs ou engins de manutention.

Patent FR-2438381-A1 (FR)
Title: Pulse generating transistorised oscillator - provides linear frequency variation with duration controlled by RC circuit
IPC: H03K3/282
Filed: 1978-10-03
Abstract: The oscillator output (B) is rectangular, its duration being largely a function of the value of a coupling capacitor (1) between the emitter and base of the first two transistors (4, 9) and that of a resistance (3) between the collector and base of these two stages. The low level state is governed by the input voltage (A) to the first transistor collector and the value of the series resistor (2) in this line. Zero voltage input to this transistor results in saturation of the final resistance (8) coupled to transistor (10).

Patent FR-2439938-A1 (FR)
Title: Visual display using single low power LV light source - which is coupled to display screen by fibre optics arrangement
IPC: H01L23/538
Filed: 1978-10-25
Abstract: A light display is formed by a screen (1) provided with a matrix of holes in which are received the ends (2) of fibre optic light guides (3). The light guides are combined in a common guide (4) which is connected conveniently to a common light source (5). The ends (2) of the guides can be arranged to provide a desired light display for decoration or public information or the like. Use of more than one light source can provide multicoloured light displays or enable the display to be altered depending on which light sources are activated. The display provides considerable energy saving since the light source can be a low voltage low power source while providing the same light intensity as, for example, neon displays. A neon sign 5m by 1m using 40m of 33 watt tubing consumes 1320 watts. An equivalent light display as described above would use only 250 watts, a saving of about 80%. Finally, a transparent or translucent screen may front the display screen (1).
