Title: Welding without porosity - by refining the large grains produced with a second weld layer
IPC: B23K9/04
Filed: 1971-05-07
Abstract: Process for welding by addn. of metal in several layers without inducing porosity at the weld-base metal interface. A plate or rod electrode is used with protective powder.

Title: Blow moulding thermoplastics - in machine producing gob, rough and blow moulding at three successive stations
Inventor: BUCHNER NORBERT DR-ING
IPC: B29C49/02
Filed: 1971-10-05
Abstract: Appts. for making blow moulded thermoplastics objects comprises three stages for forming the gob, forming a rough, then blowing this rough to the final shape; in the first stage, each one of a number of male moulds mounted on an intermittently advancing conveying device receives a gob from a mixed extrusion nozzle. In the next stage the female mould is fitted onto the male mould, and the plastics gob is pushed out from the hollow in the male mould by a piston so as to fill the mould void and form a rough; this rough is then transported on the male mould by the intermittently moving conveyor to the final, blowing station where it is blown to the final shape. In a typical arrangement three male moulds are mountd at the periphery of a rotating turntable and pass successively in front of the extrusion nozzle, the female mould station and the blowing mould station. By the overlapping of these operations, the output rate of the machine is increased.

Title: Nuclear magnetism well logging - by establishing free precession of chosen nuclei
Inventor: SLICHTER CHARLES PENCE
IPC: G01V3/32
Filed: 1972-05-30
Abstract: A nuclear magnetism well logging tool simultaneously establishes a strong DC magnetic field, to polarise chosen nuclei, and an AC magnetic field in a direction at right-angles to the earth's field and at a frequency corresponding to the Larmor precession frequency of the chosen nuclei. By terminating the DC field adiabatically over a period less than the thermal relaxation time of the chosen nuclei, the latter are swept into driven resonance in the AC field and when that field is then abruptly terminated the nuclei precess freely about the earth's magnetic field and a characteristic of the free precession is monitored.

IPC: H01L29/82
Filed: 1973-08-13
Abstract: A diode, sensitive to a magnetic field, consisting of a Si substrate with n- and p-injecting electrodes forms a current path in the forward direction when a voltage is applied.
