Patent MX-9707119-A (MX)
Title: Shaped lignocellulosic-based activatedcarbon.
Inventor: MILLER JAIMES R
IPC: C01B32/384
Filed: 1997-09-19
Abstract: Extruded pellets comprising a majority of activated carbon particles and an organic binder provide improved performance when processed through tumbling equipment while the pellets are in their "green" state, i.e., pellets which are fresh off the extruder and contain activated carbon, binder, and water and have not been subjected to any thermal processing (drying). The tumbling action both smoothes the pellets (by closing any cracks and geatly improving appearance) and increases the density of the pellets, e.g., by increasing particle density and reducing voids between the pellets. Improved performance results from an ability to increase the weight of carbon pellets which can be packed into a fixed volume and thereby increase the volumetric working capacity of the bed for adsorbing/desorbing vapors. Another benefit is to greatly reduce the levels of fust associated with the carbon, both the initial dust and the dust of attrition.

Title: Sodium alginate chitosan microcapsule containing polylisine and nisin and preparation method therefor
Inventor: JINYAN GONG
IPC: B01J13/02
Filed: 2020-07-15
Abstract: A sodium alginate chitosan microcapsule containing polylysine and Nisin and a preparation method therefor belong to the field of food engineering technology. The method has steps of: mixing Nisin with sodium alginate, dripping a calcium chloride solution to make into a calcium alginate microcapsule, then adding a mixed solution of polylysine and chitosan for secondary coating, and then coating in a sodium alginate solution again, and liquefying a capsule core with a sodium citrate solution, so as to prepare the sodium alginate chitosan microcapsules containing polylysine and Nisin.

IPC: A01N1/02
Filed: 2023-04-04
Abstract: A stem cell cryopreservation protective agent, which includes, based on the total volume of stem cell cryopreservation protective agent, the following components: glycerol with a volume fraction of 10%-30%‚ 0.6 mol/L-l.5 mol/L of trehalose, and a physiological saline or phosphate buffer serving as the solvent. The stem cell cryopreservation protective agent of the present disclosure can effectively retain the activity and function of stem cells, and has high efﬁciency, no toxicity, and xenoantigens, therefore, resulting in higher biosafety and clinical application possibilities. No polymer or biotoxic substances are employed, that is all the used reagents are non-cytotoxic, and all the used reagents are easy to elute. In addition, no xenogeneic-derived blood products and no xenoantigens are included, which guarantees the low possibility of hypersensitivity reaction. The stem cell cryopreservation protective agent is less costly and easier for operation, therefore, having a high possibility in large dose application and promotion.
Patent NL-6801296-A (NL)
IPC: G01B9/02
Filed: 1968-01-29
Abstract: 1,250,205. Measuring temperature photoelectrically. BALZERS PATENT-UND BETEILIGUNGS A. G. Dec. 16, 1968 [Dec. 21, 1967], No. 59692/68. Heading G1A. Variations in the temperature of a substrate in coating forming apparatus are measured by interferometrically investigating variations in the substrate thickness due to thermal expansion. Visible, ultraviolet or infrared light from a laser 21 passes through a window 12 into a vacuum deposition enclosure 11 and is reflected on to a substrate 17. Light reflected from or transmitted through the faces of the substrate interferes causing variations in intensity of the light received by photo-cell 25 each change from maximum to minimum intensity corresponding to a predetermined change in temperature. The transmitted interference fringes may be detected by a photo-cell 26 and indicated or recorded. The thickness of the layer being deposited may also be determined by detecting the interference of the light reflected from the front and back of the layer. If the angle of incidence of the light is suitably chosen, variations due to temperature changes may be distinguished from superimposed variations due to layer build up by their different amplitudes.

Title: Crystallization plant - with staggered propellor blades, forming a virtual archimedean screw
IPC: B01D9/00
Filed: 1971-03-26
Abstract: The saturated soln. esp. sugar syrup, is fed in at the bottom end of a long sloping cylinder, at an acute angle to the horizontal, within which is a rotating shaft carrying a number of axially staggered overlapping blades which propel the syrup along the axis to the upper end where the crystals and residual liq. are discharged as well as any vapour vented through a separate port. Viewed from the top end of the shaft the blades have the leading edge of one overlapped by the trailing edge of the next and within each section filled by a pair of blades overlapping completely i.e. with 360 degrees total displacement between their centrelines, there is continuous coverage of the circumference. The centrelines of the blades lie on a virtual spiral surface and the blades form an archimedean screw of different pitch to that spiral with tangential gaps between adjacent driving surfaces. Maximum effective crystallisation takes place due to the uniform flow and velocity distribution across the cylinder even at speeds producing a high throughput.

Patent NL-7410462-A (NL)
Title: Impact atomiser for rotor - has holes pand form thin fuel film
IPC: F02M61/02
Filed: 1974-08-05
Abstract: The mouthpiece has two or more atomiser holes so positioned that the jets from them strike each other (41, 42).

Title: Video amplifier for document scanning system in facsimile transmission - has black level adjustment and background compensation for different documents
IPC: H04N1/407
Filed: 1975-11-20
Abstract: Amplifier for a document scanning system, reacting to reflected light pattern of images producing an output representing the data contact of the scanned document. The document is subjected to a line scan, with the beam being switched off during the flyback period. The reflected beam is picked up by a photo detector whose output current is amplified. The black level adjustment circuit is operated during the flyback period and is used to control the output of the current amplifier in such a way as to compensate for the leakage current for the photo sensitive element. The background control circuit reacts to the changes in the output of the amplifier and produce compensation for the background of the scanned documents.

Title: Cleaning fluid injector for oil tanks on ships - has nozzle and feeder rotating at right angles at adjustable speeds (NO 16.2.76)
IPC: B05B3/00
Filed: 1976-01-06
Abstract: A device for cleaning the inner surfaces of oil tanks on ships and similar objects, is provided with a hose which can be inserted for the delivery of a cleaning fluid under press. It has a swivelling head assembled on the open end of the delivery pipe on the axis of which it is free to rotate, and a nozzle unit mounted on the swivelling head, freely rotatable on an axis at right angles to that of the delivery pipe. The nozzle unit has at least one nozzle, the line of ejection of which is offset to the axis of rotation of the unit so that the nozzle unit is revolved by the reactive press. of the jet of fluid delivered. A hydraulic braking device is coupled to the nozzle unit for regulating its speed via a crank mechanism on the nozzle unit shaft. A reciprocating motion of the brake mechanism set up by the crank acts through a friction plate on a pawl mechanism to regulate the rotation of the swilling head whilst the nozzle unit turns at right angles to it. A simple and reliable design. The arrangement of the hydraulic brake ensures that the rotary mechanism of the swilling head can be controlled and at the same time, a selected speed for the rotation of the nozzle can be set. The distribution of the cleaning fluid in various directions is thus optimalised.
