Title: Igniter for a mine having a pressure plate
Inventor: SCHENDEL DANIEL VAN
IPC: F42C15/285
Filed: 1986-06-27
Abstract: In the igniter of the invention, even after a change from the storage position to the arming position, the means 41 for tensioning the striking pin 40 are relaxed, and furthermore the striking pin is located in the position offset relative to the fuse 31, whilst, under the driving effect of the moveable assembly 30 fixed to the pressure plate 2, the spring is progressively put under tension and simultaneously the striking pin is put into alignment with the fuse. Thus, both in the storage position and in the arming position, there is neither a substantial storage of energy nor an alignment of a pyrotechnic chain in the igniter, the striking energy being provided from outside by the pressure exerted on the plate. There is, moreover, an active safety device by means of a buffer of microballs 52 pushed back by the lower end 38 of the moveable assembly shaped as a piston.

Patent FR-2623739-A1 (FR)
Inventor: BACCINO REGIS
IPC: B23K35/32
Filed: 1987-11-27
Abstract: The process brazes refractory workpieces which have to withstand high temperatures after brazing. It involves (a) brazing the two pieces at a temperature T1 using a brazing alloy fusible at T1 (e.g. a Pd-Ag alloy), having two constituents C1 and C2, one of which, C1 (Pd), can be alloyed with one of the basic refractory metals in the workpieces by forming an alloy fusible at a higher temperature, and the other, C2 (Ag), can be removed by volatilization; and (b) heat treating the pieces under vacuum to remove C2 (Ag) so as to obtain a joint brazed with an alloy having a higher melting point. The constituent C1 (e.g. palladium), when combining with the basic refractory metals (e.g. molybdenum, tantalum or niobium), preferably has a phase diagram with a peritectic point as shown in the figure.

Title: Support device for a telephone line
Inventor: BESSONNET EMILE
IPC: H02G7/05
Filed: 1988-01-05
Abstract: Support device for a cable, especially for a telephone cable, including a body 4 made in two parts 7-8 which are capable of defining between them an elongate continuous longitudinal passage 12, receiving the cable 13, and an element 5 for hooking the body onto a lateral cross-member attached to a carrier pole. According to the invention, the device is characterised in that the two parts 7-8 of the body 4 are capable of being mutually locked by means of a rotor 20 engaged in a bore 14 passing through the two parts once these have been applied against each other, this rotor 20 being equipped with a central hole 24 receiving the hooking element which has a part 25 forming a pivot pin for the body of the support, which part is extended on the outside of the body by a loop 30 for hanging it onto the cross-member and is terminated by a finger 31 suitable for bearing on the body 4, thereby limiting the oscillations of maximum amplitude of the latter about the pin, especially in such a way that the hooking element 5 cannot, in any position, come into contact with the cable 13 housed in the elongate passage 12 of the body.

Title: Hyperfrequency transmission line on substrate - uses ribbons above and below substrate which are connected by metallised holes to form waveguide of constant characteristic impedance
Inventor: DELESTRE XAVIER
IPC: H01P3/00
Filed: 1988-03-11
Abstract: A dielectric substrate carries three ribbons on its top side and three underneath.  The ribboins are parallel to each other and comprise a central conductor as the core and the two others as the ground.  Each ribbon on top is connected to the opposite ribbon underneath by metallised holes evenly distanced along their length. The spacing of the holes longitudinally does not affect the line characteristics provided that they are less than a quarter wavelength apart. The distance between the hole laterally and hence the distance between the ribbons determines the characteristic impedance.  This is also affected by the thickness and relative permitivity of teh substrate.  The ribbon thickness is only of secondary importance if thick metallised ribbon is used. Otherwise it has no effect. ADVANTAGE - Conductors are all in view, structure is symmetrical, and field is confined to interior of substrate.

Title: Water turbine for driving small boat - incorporates system to chop up any vegetation entering it
IPC: F04D7/00
Filed: 1988-03-09
Abstract: The device consists of three sections i.e. an inlet (1), the central section (2) and the discharge (3) which combine to form a water turbine. The inlet housing (5) is bent downwards and contains a set of fixed blades (6).  Through the side wall of this housing protrudes the drive shaft (4) which is contained inside a fixed sleeve (12). The discharge housing also contains a set of fixed blades (8) the centre of which (16) acts as a bearing support for the end of the drive shaft (4).  The centre section (5') contains two sets of impellers (9,10), attached to the drive shaft, and a set of fixed blades (7).  This centre section is removable for maintenance.  The trailing edge of the fixed blades (6) and the leading edge of the impeller (9) are in the form of hardened cutting blades which when they slide past each  other produce a cutting action which chops up any vegetation which may enter the turbine. USE - As a drive for small boats in shallow water, or as a water pump.
