Title: Quadrphonic sound equipment using dual composite signals - has four loudspeakers receiving dual compositie signals to produce phantom sound sources
Inventor: TOFALVI GYULA DR
IPC: H04S3/00
Filed: 1975-05-07
Abstract: An equipment for quadraphonic transmission of sound uses three or four channels. The equipment has four microphones (1, 2, 3, 4) located at the corners of a diamond shape.

Patent FR-2315824-A1 (FR)
Title: Automatic soldering appts - applies predetermined amt of solder to ceramic chip capacitor contacts without affecting flatness of component side
IPC: B23K3/047
Filed: 1975-06-27
Abstract: Soldering appts. includes a flat support plate made of solder rejecting metal onto which a component with contacts having flat surfaces can be loaded. A retaining mechanism positioned over the support supplies a bias force to the component towards the flat surface leaving the remaining portion of the contact exposed. A predetermined amt. of melted solder is applied to the exposed portion of the contacts whilst a sufficient force is maintained to prevent solder flowing between the flat surface of the contact and the support member. Thus the entire contact is covered with solder except for the flat surface. Used to apply additional solder to pretinned ends of ceramic chip capacitors. One surface of the component remains flat after soldering so that it will not roll off a carrying surface during automatic handling operations. More solder can be applied to the contacts than is possible with conventional solder dip bath techniques. It is not necessary to employ a special layer of solder-repellant material bonded to the component or to treat the lower surface with special solder repellant material which has to be removed later.
Patent FR-2315954-A1 (FR)
Title: Syringe for storing and mixing two medicaments - administrating the reconstituted mixt.
Inventor: VERSCHEURE DANIEL
IPC: A61M5/32
Filed: 1975-07-04
Abstract: The syringe comprises a body forming an internal chambeR, open at the top and fitted with a hollow injection needle. A tubular element is moulded in one piece with the body which has a retaining collar. The mixing component has a lower cylindrical portion which slides into the chamber. The liq., powder or granular prods. are contained in the chambers and are kept apart by the membrane. By exerting press. on the push button, the mixing piston moves downwards and breaks the membrane. This allows the liq. to pass into the chamber so that an injectable soln. is obtd. merely by agitating the assembly. Continuing the downward movement, the lower face of the injection piston with its membrane comes into contact with the free end of the needle and is ruptured. Injection proceeds until the piston butts against the stop element. The new syringe enables two medicaments, such as an active pulverant prod. and is constituting soln., to be stored separately under sterile conditions. They can then be mixed when required and the freshly constituted mixt. administered parentally.
Patent FR-2319487-A1 (FR)
Title: Metal coating of controlled porosity and thickness - applied to metal substrate, esp. for use as human heart valve prosthesis
IPC: A61F2/24
Filed: 1975-07-30
Abstract: The substrate is coated with adhesive on those zones where coating is required, and metal powder is deposited on the adhesive. This is followed by sintering to bond metals and burn off the adhesive, leaving interconnected voids round metal particles. The adhesive is pref. applied by a brush followed by the metal powder, the surplus powder being blown off by a gas so only a single layer of particles is formed. Used esp. for a human heart valve prosthesis, where body tissue can grow into the interconnecting pores. This reduces the possibility of thrombosis occurring in the year after implantation of the prosthesis.

In an example, 25g. (II) was nitrated with a mixt. of 100ml. glacial acetic acid and 100ml. nitric acid (d = 1.52) to give 22.4g. (III) m.pt. 196-197 degrees C. 18g (III) was dissolved in 500ml. methanol and 3g. Raney nickel added. Hydrogenation gave 13.6g. (I), m.pt.
