Title: Spray gun - for coating articles with electrostatically charged plastic powder
Inventor: SCHAAD HANS J
IPC: B05B5/047
Filed: 1972-11-22

IPC: A61B17/34
Filed: 1974-02-07
Abstract: A catheter slides in a first large hollow needle, and has a length of tube with first and second end areas and diameter less than the passage in the needle. A thin needle section at the first end area has a passage in it and, at a distance, a point piercing the tissue wall. The passage in the needle communicates with the length of catheter tube. An oblong stiletto longer than the length of tube, has one of its ends inside the latter and the other outside, and slides coaxially in the tube, being smaller than the passage in the needle section. Means are provided on the stiletto end inside the tube and the thin needle section to enable tube and thin needle to be thrust forward in relation to the large needle after this has been used, in order to insert the thin needle to a predetermined depth during a second stage of penetration. After this the stiletto is removed and material can be injected through the tube and thin needle.

Title: Electron microscope heated shutter holder - has heat conductive element between holder and heat source spaced for beam protection
Inventor: SIEBER PETER DIPL PHYS
IPC: H01J37/09
Filed: 1974-03-29
Abstract: The heatable shutter holder is intended for an electron microscope and is connected via a thermally conductive component with an electrically heatable heat source. This source is arranged at such distance from the electron microscope axis that it does not generate any noticeable interference field for the particle beam. Preferably the heat source is arranged outside the microscope housing. The thermally conductive component may be formed by a flexible copper wire strand, or a heat pipe. This arrangement enables to keep the shutter temperature in operation within 100 to 200 deg.C, thus preventing any contamination or charging of the shutter.
