Title: Reflector for direct central measurement of angle and distance - has tiltable, displacement mirror for surveying
Inventor: GUENTHER MARKUS DIPL ING
IPC: G01C15/02
Filed: 1990-08-08
Abstract: A reflector (1) for direct, central measurement of angle and distance in a single measurement process consists of a prism with a housing. A mirror (2) in a housing (4) is mounted vertically above and at a fixed distance from the reflector which is mounted rigidly in a frame (3) to which the housing is attached. The mirror is at 45 deg. to the vertical and can be tilted and displaced with interdependence of these motions.

Inventor: KOEHLER MICHAEL
IPC: H01L35/34
Filed: 1991-01-16
Abstract: Thermoelectric sensors are made as follows: on a substrate (1) a first, thin conductor layer (4), pref. NiCr, is deposited, followed by a thicker contact layer (5), pref. Al, which are etched into the required pattern. Then the top layer (5) is etched back from the edge of the first layer (4) pref. forming sloping flanks. The first thermoelectric layer is deposited in such a way that only the edge of the first (4) contact layer is overlapped, and the layer patterned. The second thermoelectric layer is formed also overlapping only the edge of the thin contact layer, and patterned. Then a passivation layer is deposited, a thermal relief layer and an absorption layer. The first contact layer is pref. etched prior top deposition of the thermoelectric layers. The etch bath compsn. for the etching of Sb-layers is a watery soln. of an oxidation agent with a Redox potential of more than 0.2, pref. 1-20,wt.% of ammonium-peroxodisulphate, and a hydroxydicarbonic acid, pref. 6.1-10wt.% tartaric acid or a deriv. e.g., a salt. The soln. pH is 1-4, pref. 1.2-1.9. Also claimed to etch Sb or Bi layers is a soln. contg. 1-20wt.% of the above oxidant and a hydroxytricarbonic acid, pref. 5-30wt.% citric acid, or a salt or deriv., at a pH of 1-4, pref. 1.1-1.4. To the soln. can also be added 1-2wt.% of a ferric salt. Also claimed is a thermoelectric pile using series-connection of several pairs of the metallic layers. USE/ADVANTAGE - The construction avoids the thin thermoelectric layers having to overlap the high and steep edges of the contact areas as in conventional devices.

Title: Medical infusion pump or injection syringe - operated by osmotic pressure
Inventor: ZERBST EKKEHARD PROF DR MED
IPC: A61M5/145
Filed: 1991-02-27
Abstract: A medical pump and/or injection syringe, for gradual infusion of solns. and/or dissolved medicaments into blood vessels, tissue and/or organs of patients, is claimed. The pump is operated by salination forces produced by two fluids of different concns. located on opposite sides of a partition in the form of semi-permeable tubes or capillaries, the higher concn. fluid being diluted and increased in vol. by osmotic transfer of solvent from the lower concn. fluid. The resulting osmotic pressure is transferred as the operating pressure to the space behind the pump piston to produce a piston drive proportional to the volume and for pressure increase of the higher concn. fluid. ADVANTAGE - The infusion pump and/or syringe has a simple osmotic drive which can be controlled by choice of the fluid concns. and the membrane wall thickness.

Title: Light source system for endoscope with variable colour reproduction - has at least one colour filter transmitting additionally IR of specified wavelength
Inventor: ADACHI RENSUKE
IPC: F21V9/00
Filed: 1991-03-25
Abstract: The system has several colour filters, sequentially brought into the illumination light transmitting optical fibre of the endoscope. At least one colour filter (23R,G,B) is so designed that it is transparent for IR of specific wavelength range in addition of the visible, light. A first IR filter (24I) blocks the IR beams, while a second IR filter (24J) transmits the IR beams in the specified wavelength range, but blocks visible light from the colour filter. The two IR filters are selectively brought into the illumination path by a selector (22). Pref.  the alternative engagement of the IR filters is carried out in synchronism with the colour filter application. USE/ADVANTAGE - Provides facility for normal colour observation and for image processing illumination.

Inventor: RITTER WOLFGANG DR
IPC: A61K47/34
Filed: 1991-04-17
Abstract: A first embodiment of the invention concerns the use of radically reactive crosslinking components based on olefinically unsaturated esters of low hydroxycarboxylic acids and/or their oligomers to modify depot materials, in particular retard systems, containing medical and/or biological valuable substances admixed with a carrier material, for the delayed release of the active substances. The crosslinking agents are present as polymer compounds in the application form of the retard system and may be distributed uniformly or non-uniformly in the retard system or depot material. The invention also concerns retard systems containing medical and/or biological valuable substances and based on oligomer and/or polymer compounds of low hydroxycarboxylic acids as carrier material providing  delayed release of the active substances. The invention is characterized in that these retard systems or depot materials are modified with polymer compounds of olefinically unsaturated esters of low hydroxycarboxylic acids and/or their oligomers.
