Title: Stereoscopic xray analyzer for medical and - material testing
Inventor: REICHMANN MAX DR
IPC: G01N23/04
Filed: 1969-09-10
Abstract: The object to be examine is illuminated from behind with a diffused wide angle beam of X-rays from a source with a wide focal field. It is viewed by a portable binocular type device not rigidly connected to the rest of the equipment and without any intervening image screen. The image in each half of the eyepiece is developed in a so called Roentgen lens which consists of two honeycomb plates with a plain fluorescent plate between them, a front multi-aperture stop covered in material transparent to X-rays but opaque to visible light and a rear plate containing a matrix of small optical lenses thus constituting a multi-channel image converter each channel having a filtered stop, two cells, with an intermediate fluorescent element and a rear lens. To minimize length and increase in field of view, this is followed by the normal set of positive lenses and then by image intensifier and eyepiece.

Patent DE-2004160-A1 (DE)
Title: Hydraulically assisted mechanical extrusion press
Inventor: WASSEN JOHANN
IPC: B21C23/21
Filed: 1970-01-30
Abstract: Mechanical extrusion press for billet piercing and tube extrusion comprises an upper punch and a mandrel both of which are actuated by the cam shaft, but where the action of the punch is reinforced by the pressure exerted by at least one hydraulic cylinder which is effective near the bottom dead centre of the cam movement at the end of the working stroke.

Patent DE-2056318-A1 (DE)
Title: Stabilisation of photographs - on organic photosensitive material, using peroxides or other cpds with reactive oxygen
IPC: G03C1/675
Filed: 1970-11-16
Abstract: Pictures and background areas are stabilised by treatment with a soln. of a stabilising amt. of a substance having a reactive O atom. The photosensitive combination consists of a) an organic halogen cpd. which forms free radicals or ions when exposed with light of suitable wavelength and contains at least one halogen, e.g. Cl, Br and I, bound to C atom which is bound to not more than one H atom; and b) an aromatic cpd. contg.

These photographs can be used as masters in diazo and other reprodn. processes. Treatment prevents darkening in background areas and allows material to be exposed repeatedly with light of any wavelength.

The torch may be mounted for transverse movement across the carriage.
Patent DE-2107222-A1 (DE)
Title: Superimposed high frequency control - for arc welding sets with relay actuated by no load voltage
IPC: B23K9/067
Filed: 1971-02-16
Abstract: A pilot ignition generator producing 3kV at a frequency of 80 MHz is switched on by a relay when the no-load d.c. welding voltage of 70V is present. This assists in starting the arc. When this voltage drops to the working voltage of 12V, relay and generator are cut off. A low-pass filter protects the relay coil against the HF pilot voltage. This produces excellent arc-welded seams in Ti alloys.

Title: Deacidification of esterification prods - by passing drops through alkali soln,for salt-free plasticiser esters
Inventor: CHAJDUKOW GENNADIJ FJODOROWITS
IPC: B29C47/54
Filed: 1971-09-02
Abstract: Esterification prod. is freed from acid by dispersing it in drops in 2-20 wt.% alkali according to the acid used for esterification, and in a layer thick enough to allow diffusion of the acid from the inside to the surface of the drops whilst these are rising in the denser alkali soln., so that neutral salts are formed and pass into the alkali soln. The prod. is obtd. by esterification of monohydric alcohols with carboxylic acids in the absence of catalyst or in the presence of an acid catalyst. After deacidification, it is purified by distn. or treatment with sorbents. This technique can be used in the prodn. of esters used as intermediates in organic syntheses and as plasticisers for polymers.

Patent DE-2361957-A1 (DE)
Title: Gas-heated double-walled cooking vessel with safety cut-out - has thermostat element cutting of gas supply when liquid level drops
Inventor: UNGER ERICH DIPL ING
IPC: A47J27/62
Filed: 1973-12-13
Abstract: The doubled wall cooking vessel is operated by filling the cavity between the two walls with water which is then boiled by a burner until it evaporates and condenses against the inner wall, thereby cooking the food on the other side. To prevent the water from boiling away and the vessel from exploding a thermostat element which actuates a contact in the circuit of the thermoelectric ignition fuse is mounted at the bottom in the liquid level with the gas burner. This safety fuse which is already fitted in this type of vessel to operate if the flame goes out can now also be used for this extra purpose. The thermostat which in the normal way is covered with water only operates when the water has boiled away to leave it exposed.
