Title: Optical registration tape.
Inventor: PUT PAUL LOUIS MARIE
IPC: G11B7/24
Filed: 1996-09-26
Abstract: A method of manufacturing a read-only optical registration medium in the form of a flexible tape, comprising the following steps: (a) providing a flexible substrate (1) in the form of a tape; (b) providing an embossable registration layer (3) on the substrate (1); (c) embossing the registration layer (3) under pressure with the aid of stamper, so as to form a pattern of high and low surfacial regions (5) representing a collection of binary data; (d) providing a protective film (9) over the embossed registration layer (3). This procedure can be used to produce a novel read-only optical registration medium in the form of a flexible tape with a layered structure which successively comprises: a substrate (1); a registration layer (3); a reflective registration surface (7), in which binary data are represented by localised level-variations (5'), and a transparent, optically-smooth protective film (9), in which there is no metallic reflection layer between the substrate (1) and the registration layer (3), and in which the side (1a) of the substrate (1) remote from the registration layer (3) is rougher than the exposed surface (11) of the protective film (9).

Title: A method and apparatus for improving measurement accuracy
Inventor: NITESH PANDEY
IPC: G03F7/20
Filed: 2016-01-20
Abstract: An optical system (10) includes an arrangement for splitting a source beam into a measurement beam and a reference beam. The reference beam is reflected off a reflective element (42) which mounted on a delay line (44). A target (35) scatters the radiation from the measurement beam. The scattered radiation and the reference beam are brought to interfere on a detector (40) by calibrating the delay line (44). The detected interference pattern is Fourier-transformed and filtered to select a region of interest around a side-band of the Fourier-transformed interference pattern in order to remove noise caused by stray radiation that hits the detector.

Title: Nitrification inhibitor protecting agent and application thereof
Inventor: ZHIJIE WU
IPC: C05G3/90
Filed: 2021-12-26
Abstract: Described is a nitrification inhibitor protecting agent and an application thereof, and belongs to the field of fertilizers. The nitrification inhibitor protecting agent includes poly(3- hydroxybutyrate) valerate (PHBV). The present disclosure further provides an application of the nitrification inhibitor protecting agent in a nitrification inhibitor and in a fertilizer. In the present disclosure, the PHBV serves as a protecting agent of a nitrification inhibitor DMPP and can significantly enhance stability of the DMPP, so that an effect of the DMPP for inhibiting nitrification is significantly enhanced. On the basis of taking the PHBV as the nitrification inhibitor protecting agent, addition of an appropriate amount of bentonite can further improve a protective effect of the DMPP and enhance a nitrification inhibition effect of the DMPP. The nitrification inhibitor protecting agent in the present disclosure is applicable to a spraying technology for preparing fertilizers and also applicable to a melting method for preparing fertilizer granules, thereby reducing solvent cost and process difficulty.

Title: Transport and conditioning of heat - by sepg. volatiles from two component mixt. and recombining at heat delivery point, using compressor to upgrade heat to desired temp.
IPC: F24D11/02
Filed: 1978-01-17
Abstract: Heat is transported and conditioned by circulating a two component mixt. Heat available on the feed side is used to separate the mixt. into a single component vapour and a liq. mixt. poor in the first component. The vapour is then condensed by passing through a heat exchanger through which water from a cooling tower is passed, transported through a pipeline to the point where the heat is required, expanded and warmed, e.g. by low temp. heat from water out of a cooling system and is then recondensed whilst giving up heat to the liq. phase. The liq. passes through a heat exchanger where it gives up its heat to the heat sink and is pumped back to the start point. The heat sink consist of a similar two phase system in which the vapour phse is compressed to raise its temp. and the heat is then given up to e.g. a water heater as it is mixed with its liq. phase. The proportion of the volatile component to the liq. component can be varied to suit the conditions under which heat is to be removed and delivered. The sytem is suitable e.g. for utilising waste heat from industry for a district heating scheme. The use of the second stage enables the final temp. of the vapour to be determined as a function of the pressure giving some flexibility of choise of temp.

Patent NL-7905879-A (NL)
Title: Mechanically operated pressure dispenser - has expansible bulb connected with accumulating chamber and dispensing nozzle, and having volume capacity several times greater than chamber
IPC: B05B9/08
Filed: 1979-07-31
Abstract: The mechanically operated dispenser has a rotatable actuator connected with at least one expansible chamber to effect operation of the latter to draw material to be dispensed from a container into the expansible chamber to then pressurise the material. An expansible bulb is connected with the chamber and with a dispensing nozzle, and has a volumetric capacity several times as great as the expansible chamber. Valves are associated with the bulb to control flow into and out of the bulb, whereby the rotatable actuator and expansible chamber are operative to repeatedly draw material from the container, pressurise it and transfer it under pressure into the bulb. The bulb expands as material is added to it, and the elasticity of the bulb acts to exert a substantial pressure on the material in the bulb. Subsequent operation of the dispensing nozzle releases the material from the expanded bulb, and the bulb returns to its normal, at-rest condition.
