Patent GB-201316355-D0 (GB)
Title: Cycled preparation method that uses sodium fluoborate as intermediate raw material and produces boron element and simultaneously sodium cryolite
IPC: C01F7/762
Filed: 2012-04-29
Abstract: The disclosure discloses a method for cyclically preparing monomer boron and coproducing sodium cryolite using sodium fluoborate as an intermediate material, which includes the following steps: A) adding hydrofluoric acid to boric acid or boron oxide to enable a reaction to form fluoboric acid; B) adding a sodium carbonate aqueous solution to the fluoboric acid to enable a reaction to form the sodium fluoborate; C) putting the sodium fluoborate into a reactor, adding aluminium to react with the sodium fluoborate to form the monomer boron and sodium cryolite, or, putting the aluminium into the reactor, and adding the sodium fluoborate to react with the aluminium to form the monomer boron and sodium cryolite; D) extracting the sodium cryolite, sending the sodium cryolite to a rotary reaction kettle together with concentrated sulphuric acid to enable a reaction to form hydrogen fluoride gas and aluminium sodium sulphate, collecting the hydrogen fluoride gas and dissolving it into water to obtain the hydrofluoric acid; E) recycling the obtained hydrofluoric acid to Step A to leach the boric acid or boron oxide. The disclosure can recycle the coproduct sodium cryolite, thereby shortening the process of preparing monomer boron, reducing the comprehensive cost of production, improving the production efficiency and reducing environmental pollution.

Title: Process for detection of blood-borne parasites
Inventor: LEVINE ROBERT AARON
IPC: G01N33/48
Filed: 1979-12-01
Granted: 1984-09-27
Abstract: A process for detecting parasites which are found in the blood of a host. A sample of blood is drawn into a capillary tube which contains a generally cylindrical mass having a specific gravity such that it will float in one of the cell layers when the sample is separated by centrifugation. The specific gravity of the mass is selected so as to cause the cylindrical mass to combine with the bore wall of the capillary tube to form a thin annular space in the capillary tube into which the parasites will be crowded, thus increasing the concentration of parasites in a restricted area of the centrifuged blood sample and rendering the parasites highly visible. A stain may be used to differentially color the parasites. One specific parasite which can be detected in this manner quickly and inexpensively is heartworm.

Title: Time switches for central heating systems
Inventor: JACKSON HAROLD ERNEST
IPC: G05D23/19
Filed: 1980-01-22
Granted: 1984-05-10
Abstract: A time switch (100) comprises terminals (110) spaced around a slip ring (108) connected to a voltage source (V). A motor (104) drives a brush (102) to sequentially connect the terminals (110) to the slip ring (108) to energise the terminals in sequence. Each terminal (110) - as shown for one of them designated 112 - is connected via a respective transistor (116) and manually operable switch (124) to a pair of common output conductors or bus-bars (130, 132), whereby for each successive period of time corresponding to each successive terminal (110) being energised the conductors (130, 132) are energised in accordance with the setting of a respective one of the switches. Thus, a desired time-varying pattern of energisation of the conductors (130, 132) to accomplish a control function, e.g. the control of a central heating system to provide different heat outputs at different times of the day, can be set up at will simply by adjusting the various switches (124).

Title: Portable power saw mill
Inventor: ELSEY PAUL
IPC: B27B15/02
Filed: 1981-11-06
Granted: 1986-04-30
Abstract: A portable bandsaw mill, readily made sufficiently light in weight to be carried by two people, having a saw unit supported on rollers, so that the saw unit can be readily guided and the cut controlled and adjusted manually. A ground-supported support frame or unit provides guide tracks spaced apart on opposite sides of a log or other workpiece, on which the saw unit can be rollingly advanced. The ends of the guide tracks are supported in end frames by structure enabling the levels of the guide tracks to be conveniently adjusted for successively lower passes of the saw unit through the log. Guide beam ends are capable of independent adjustment to accommodate differences in level between the four corners of the support unit. A manually advanced rolling saw head of the saw unit includes two bandsaw pulleys, each having a bandsaw blade entrained thereon, one being an idler pulley and the other a drive pulley. The drive pulley, rotatably driven, can be powered by a hydraulic motor, with the actual pressure fluid source separate from the mill. The motor can be readily separable from the saw unit for use in powering other apparatus. The mill can be readily employed for rip sawing logs into boards at any convenient location for example the felling site.

Title: Image display system
Inventor: AMANO TADASHI
IPC: G03B27/73
Filed: 1982-11-04
Granted: 1988-03-31
Abstract: The image display system of this invention is intended for use in the artificial diagnosis of print exposure requirements when making prints from the images on photographic film. In particular, it relates to printing from colour negative film on the basis where a large number of films are sequentially joined together by adhesive tape to form a long continuous roll. The video camera (21) scans the images on the continuous roll of film (20) with the video signal being transmitted through an image processing circuit (23) in which an image reproduction level is set. When the quantity of transmitted light through the detector (22) is controlled so as to be constant, to image frames (F1 to F12) of the negative film, then the reproduction system in the integrating neutral process is completed. Twelve successive images are sequentially memorised in the memory circuit (25) and displayed on the screen (26). If a faulty, blurred or defective image arises then a judgement is made as to whether or not to print that image.

Title: Monopulse detection systems
Inventor: HALFORD GORDON JOHN
IPC: G01S13/44
Filed: 1983-11-09
Granted: 1988-11-17
Abstract: The monopulse system comprises a plane array of detectors responsive to the energy received from a target. A sum channel adds together outputs from all detectors and a difference channel applies a fixed polar phase delay which is linear in the range (0-2), or an integral multiple of it, to the output of each detector in dependence of the angular position of each detector in the plane of the array. The difference channel also adds together the product signals thus formed. The outputs from the two channels are compared to derive the position of the target. Only two channels are thus required, one of which produces a sum beam and the other a difference beam in which the relative amplitudes determine the target's angular off-set and the relative phases determine the direction of this off-set as projected on the plane of the array.

Abstract: A combinatorial circuit component for television sets with an overload protection circuit on the primary side and a secondary-side regulating circuit and starting circuit with final disconnection of the mains section. The protective circuit, which comes into play in the event of anomalies on the primary side, causes a jump in the negative voltage on the secondary side. This is compared with a secondary (standby) voltage, created independently of the combinatorial circuit, in a comparator, which supplies a control voltage to which the secondary protection circuit responds thus interrupting the excitation of the switch in the mains section.
