Title: Preparation of slide mounted blood sample - including exposure to fixing agent to maintain cell morphology
Inventor: BACUS JAMES WILLIAM
IPC: G01N33/483
Filed: 1979-07-05
Abstract: A blood specimen consisting of a monolayer of sepd. blood cells is prepd. on a slide suitable for automated analysis. A sample is spun on the slide about an axis perpendicular to a support for a short time to develop a monolayer. This separates the red blood cells and throws excess cells radially outwards to form an evenly distributed monolayer. This monolayer is subjected to a fixing agent subsequent to the spinning operation and prior to drying. This fixes the natural shapes of the cells before they flatten during drying. The slide is finally dried. The method is used to prepare a blood cell specimen for diagnostic analysis. The cells are fixed during a critical step of their preparation so that their morphology is preserved for later analysis.

Title: Evaporator for heat sensitive solns. - having heated rotor with series of conical shells over which soln. flows
Inventor: PELZER RUDOLF DIPL ING
IPC: B01D3/10
Filed: 1979-07-09
Abstract: Solutions are concentrated in an evaporator with a heated rotor mounted inside a shell to which vacuum can be applied and the vapour produced drawn off. The soln. is fed to the inner edge of the rotor and spreads as a thin film over its surface. The rotor has a series of heated shells or jackets which have a steam supply to them. These have a conical profile so that the liquid runs over their surface due to the centrifugal action. The general profile is zig-zag so that the liquid moves progressively out through the rotor until it is finally thrown onto the shell. Used for concentrating solns. The process allows both a high vapour load for heat sensitive materials and a high vapour load where evaporation is tailored to certain prods. requiring a special temp. load.

Title: Simple switch for magnetisation coil of colour TV tube - has PTC or NTC resistor heating bimetal switching device and held in casing by spring clip
Inventor: JERNEY RUDOLF ING GRAD
IPC: H01C7/02
Filed: 1980-08-06
Abstract: The switch has a PTC or NTC resistor thermally coupled to a switching device via a large-area centre electrode. The resistor is also connected to an outer electrode. The resistor heats the switching device, which then changes its state. The resistor, the switching device and the electrodes are located in a pot-shaped plastic moulded casing (26) having a slot in one wall through which the connection tags (4,5,49) of the centre electrode (7) and the outer electrodes (8,50) project. A spring clip (51) closes the casing and is U-shaped with hooks at the ends of its limbs that locate around inward-sloping ledges at the closed end of the casing. The clip's spine is shaped so as to increase the force with which it acts on the resistor (15) and the switching device (16). The bracket may simultaneously act as one of the two outer electrodes, in which case it has a connection tag. The switching device may be a bimetal strip or a ceramic resistor heated by the first resistor. Variants of the basic switch are described. The advantage lies in the extremely simple components employed and their assembly.

Title: Automatic optical position detection system - uses coaxial scanning and measuring beams to form three=dimensional image
Inventor: SLAVIK JOSEF DR
IPC: G01S17/42
Filed: 1980-11-28
Abstract: The position monitoring system for a selected object uses a modulated optical scanning beam which is automatically deflected to impinge on the object with a partial beam reflected from the latter being detected by a photosensor. The scanning beam and the measuring beam extend approx. coaxially and are deflected in conjunction with one another. The photodetector signal is used to measure the distance of the point on the object from which the measuring beam is reflected, in dependence on the angle of the scanning beam, so that a 3-dimensional image of the object can be built up, from which its position within the room is determined. The system can be used for a fully automatic industrial assembly plant to determine the position of the components.

Patent DE-3046931-A1 (DE)
Inventor: SAGER JOHANN
IPC: H01H33/56
Filed: 1980-12-12
Abstract: A rubber sealing element (3) is firmly fitted, in a gas tight manner, on the drive element (2, 18, 19) and on the housing (1, 10). It thus bounds a space (20), which is completely filled with liquid, opposite the housing interior (4) which contains an increased gas pressure (P). The cover (13) thus needs to have only liquid seals (15, 16) with respect to the housing (1), which seals act as gas seals without any problems. The sealing element (3) can have virtually any desired shape since the liquid in the space (20) can assume any shape and nevertheless prevents friction of the sealing element (3) on the shaft (2) and other walls of the space (20). Freedom from wear is thus possible despite a small structural size. Any liquid emerging from the seals (15, 16) would be visible without having to worry about gas already emerging, since the sealing element (3) can remain temporarily serviceable in the event of oil loss. <IMAGE>

Title: Fine-grained expanded granules and process for their production
Inventor: WUESTEFELD BERND DR
IPC: C04B14/18
Filed: 1981-01-30
Abstract: Perlite having a grain size of preferably 0.1 to 0.6 mm is mixed with a glazing material which, before reaching the expanding temperature of the perlite, forms a film of glassy melt on the individual perlite particles. If the particles are then heated up to the expanding temperature of the perlite while in constant motion, granules having a grain size of less than 3 mm and a strength of the granule particles corresponding to the strength of sand are obtained. These granules are used in particular, preferably on their own, as an aggregate for plastering mortar, with which insulating plasters with a very high insulating value can then be produced. The preferred glazing material used is a suspension of colloidal perlite in a concentrated solution of phosphates or of silicates and borates in water. The colloidal perlite is readily obtained from perlite expanded in a conventional way.
