Patent FR-2303018-A1 (FR)
Title: Ampicillin prepn. from natural penicillins - by conversion into 9-anthrylmethyl ester of ampicillins and hydrolysis of the ester
IPC: C07D499/00
Filed: 1974-07-31
Abstract: Prepn. of ampicillin is new by converting the 9-anthryl methyl ester of a natural penicillin e.g. benzylpenicillin, into the 9-anthrylmethyl ester of ampicillin. This ester is hydrolysed with an acid (trichloroacetic acid) or a base (alkylmercaptan Na salt). The 9-anthrylmethyl esters of benzyl penicillin and ampicillin are new. The use of 6-APA is avoided. The ester group protects the beta-lactam ring and is readily removed. Penicillins G or V are converted into their 9-anthrylmethyl esters, then into the iminohalides and iminoethers. The latter react with reactive derivs of phenylglycine to give the 9-anthrylmethyl ester of ampicillin. Hydrolysis gives ampicillin.

Patent FR-2244595-A1 (FR)
Title: Friction welding of metals under water - using plastic sleeves for thermal insulation of parts being welded
IPC: B23K20/12
Filed: 1974-09-23
Abstract: The two parts are located so their end faces are in contact, a relative rotary motion is applied, e.g. by clamping one part and rotating the other, and the two ends are pressed together, the weld being made due to the combination of the frictional heat and the pressure. Prior to welding, a thermally insulating material is wrapped round the peripheries of the parts adjacent the joint. This reduces heat losses due to thermal conduction between the hot metal and the water, and permits welding in deep water, with water-pressures up to 50 kg/cm2.

Title: Simulator for crossbar telephone exchange - uses computer based testing circuits during installation of an exchange
Inventor: BADORREY JOAQUIN CORDERO
IPC: H04M3/32
Filed: 1975-12-29
Abstract: This simulator, which is computer controlled, is intended to be used during the construction of a cross-bar type telephone exchange which may have interconnections for rotary exchanges or telex systems. The multiple units of the simulator such as the multiplexer sender preselector etc., link to the computer and other parts of the exchange.
