Patent DE-2457401-A1 (DE)
Title: Adjustable electron microscope specimen holder - consists of sliding specimen carrier movable along to axes by two actuators
Inventor: UNWIN DONALD JOHN
IPC: H01J37/20
Filed: 1974-12-05
Abstract: The adjustable specimen holder consists of a sliding element carrying the specimen and abutting two actuators, imparting to it a motion along two preset axes. For this axial motion the sliding element is supported by a surface of the microscope frame, against which it is held by spring members, the latter being used by the actuator for one axial direction as transfer elements. This actuator consists of two parallel relatively fixed, elongated parts cooperating with the sliding element which is held between them by the spring members. The two elongated parts are movable along an axis at right angles to their own axes. The two elongated parts serve also as a guide element when the sliding element is to be moved by the second actuator along a second axis parallel to the parts own axes.

Title: Chlorinating and sulphochlorinating alkanes - with part product recycling to improve wetting props of saponified alkane sulphonate
Inventor: SCHLECHT HELMUT DIPL ING DR
IPC: C07C19/10
Filed: 1974-12-14
Abstract: Process for prepn. of Cl atom- and SO2Cl gp. - substd. 5 + C alkanes, by reaction of >=1 mol Cl and 1 mol SO2 for each mol alkane, takes place with recycling of 3-40 (5-20) wt. % of reaction prod. leaving reaction chamber to reactor. Raw materials are charged upwards, at gas layer velocity 2-30 m/sec., for a gas layer dwelling period of 2 - 60 secs. to a reaction chamber the longitudinal axis of which forms an angle of 1.5-30 degrees with the horizontal. Prods. can be saponified to alkali sulphonates. Recycling step reduces quantity of unreacted alkanes and over-chlorinated - or over-sulphochlorinated cpds. and prevents discolouration. Saponified products are excellent wetting agents. Heat-transfer from reaction mixt. to tubular reactor walls is improved. Process is photolytic. All right-sources radiating in visible range can be used, esp. those having high proportion of radiation at wave-length 3000-5000 angstroms.
Patent DE-2461061-A1 (DE)
Title: Respiratory air humidifier for tracheostomy patients - with air warmed to body temp and saturated with moisture
Inventor: SCHULTZE HANS A DIPL ING DR
IPC: A61M16/16
Filed: 1974-12-23
Abstract: The repiratory air humidifier warms the air to body temperature and saturates it with moisture but without leaving water droplets or aerosol particles in the air which can penetrate a long way into the bronchial system and have an undesirable cooling effect. Pref. behind the vaporizing zone is a steam-moisturizing system producing the required vaporizing effect. A pure surface vaporizer is used to humidify the air whilst preventing formation of a particle mist. A high energy sterilizing particle filter is inserted in the apparatus outlet. This removes bacteria and germs which are breathed out.
Patent DE-2503802-A1 (DE)
Title: Sash window scissor suspension - has lengths exceeding those of bottom scissors which are adjustable at optional angle
Inventor: JACOB GERNOT
IPC: E05D15/20
Filed: 1975-01-30
Abstract: The scissor arrangement allows the panel to be lifted-off from the closed position plane, to clear the plane of the stationary half of the window. For sufficient clearance the scissor have to be of considerable length, resulting in high bending moments on the arms of the scissors. To overcome this the ends of the suspension cable are connected to vertically positioned scissor arrangement with arms (8, 11) with the other ends jointed to the side of the frame (62) of the window pane. The scissors are subjected to tensile loads only, with reduced wear on the joints. The arms (8, 11) are considerably longer than those of at the bottom of the window so that the angle can be set as required.
